Congenital dysphagocytosis is an old medical name for a serious inherited immune system disease that doctors now call chronic granulomatous disease (CGD). In this disease, some white blood cells called phagocytes (mainly neutrophils and monocytes) look normal in number, but they cannot properly “eat and kill” germs, especially some bacteria and fungi. Because of this, the person gets repeated, sometimes life-threatening infections and forms lumps of inflamed tissue called granulomas in many organs.
The word “congenital” means the problem is present from birth and is usually caused by a gene change passed down in families. The word “dys-phagocytosis” means “phagocytosis that does not work properly.” Phagocytosis is the normal process where a white blood cell surrounds, swallows, and destroys germs or dead cells. In congenital dysphagocytosis, this killing step is faulty, so the germs survive inside the cell.
Congenital dysphagocytosis is an older name for a rare inherited immune system disease that today is usually called chronic granulomatous disease (CGD).[1] In this condition, some white blood cells called phagocytes (mainly neutrophils and macrophages) are present in normal numbers, but their “killing machinery” does not work properly. Because the NADPH oxidase enzyme in these cells is faulty, they cannot make enough reactive oxygen to destroy certain bacteria and fungi after they swallow them.[2] As a result, patients have repeated, sometimes severe infections and form firm lumps of inflamed tissue called granulomas in organs such as the skin, lungs, liver, gut and lymph nodes.[3]
Congenital dysphagocytosis is usually diagnosed in childhood, but milder forms can appear in adults.[1] It is often inherited in an X-linked pattern (males affected, females carriers) or autosomal recessive pattern. Modern treatment focuses on three big goals: (1) prevent infections with daily antibiotics and antifungals, (2) boost immune function with medicines like interferon-gamma, and (3) consider curative options such as bone marrow (stem cell) transplant in selected patients.[4] With careful lifelong medical care, many people can live into adulthood with much better quality of life than in the past.[5] [1]
This condition is part of a group called “primary immunodeficiencies,” which are diseases where parts of the immune system are weak because of inherited genetic defects. People with congenital dysphagocytosis can seem healthy between infections, but they are always at high risk for deep infections in the lungs, skin, lymph nodes, liver, bones, and gut. Early diagnosis and expert care are very important to prevent damage and improve life expectancy.
Other names
Congenital dysphagocytosis is rarely used in modern practice, but it appears in older medical literature and in some disease lists as a synonym for chronic granulomatous disease. Different authors and centers have used several names for the same or very similar disorders.
Chronic granulomatous disease (CGD) – This is the most common and current name. It describes the long-lasting disease (“chronic”) in which the body makes many granulomas (small nodules of immune cells) in response to infections it cannot clear.
Fatal granulomatous disease of childhood – This older term was used when many affected children died early from severe infections, before modern antibiotics and bone marrow transplant options existed.
Congenital dysphagocytosis – This historical name stresses that the main problem is a birth-defect of phagocyte function, not their number. It is now mostly seen in older articles and indexing systems.
Chronic septic granulomatosis – This name focuses on repeated “septic” (bacterial) infections that lead to many granulomas in organs like the liver and lungs.
Bridges–Good syndrome / Quie syndrome – These are eponymous names given after researchers who described families with this condition; they are rarely used now but still appear in some references.
Types of congenital dysphagocytosis
Doctors group congenital dysphagocytosis/CGD into types mainly by which gene is affected and how it is inherited. All these genes encode parts of the NADPH oxidase system, the enzyme group that creates the “respiratory burst” needed to kill swallowed germs.
X-linked CGD (CYBB gene defect)
This is the most common type. A mutation in the CYBB gene on the X chromosome affects the gp91^phox subunit of NADPH oxidase. Boys usually get this form, and it tends to be more severe, with earlier and more frequent infections.Autosomal recessive p47^phox deficiency (NCF1 gene)
In this type, both copies of the NCF1 gene are changed. The p47^phox subunit is missing or not working, so the oxidative burst is weak or absent. Disease can be as severe as the X-linked form or sometimes milder, but patients still get serious infections.Autosomal recessive p67^phox deficiency (NCF2 gene)
Here, mutations in NCF2 damage the p67^phox subunit. Neutrophils may reach infection sites but cannot produce enough toxic oxygen products to kill germs, leading to chronic infections and granulomas.Autosomal recessive p22^phox deficiency (CYBA gene)
This rare form involves the CYBA gene, which encodes p22^phox. The whole NADPH oxidase complex becomes unstable. Patients often have early-onset, severe infections similar to the X-linked form.Other rare NADPH oxidase component defects (e.g., NCF4 and related genes)
A few patients have mutations in other helper proteins that regulate or assemble the oxidase complex. These forms are rare, but they show that many pieces are needed for normal phagocyte killing.Clinically defined CGD without identified gene (very rare with modern testing)
In some older series, patients clearly had clinical CGD but no gene studies were available. Today, advanced genetic tests can find variants in most patients, but a small number still remain genetically undefined.
Causes
Here “causes” means the underlying reasons and conditions that lead to congenital dysphagocytosis or make it more likely in a family. All are linked to genes or inheritance, because the disorder is congenital.
Mutation in the CYBB gene (X-linked)
A harmful change in the CYBB gene on the X chromosome is the main cause of X-linked congenital dysphagocytosis. This gene encodes gp91^phox, a core NADPH oxidase subunit. When this protein is abnormal, phagocytes cannot mount a normal oxidative burst, so they cannot kill certain bacteria and fungi.Mutation in the NCF1 gene (p47^phox deficiency)
Two faulty copies of NCF1 cause a missing or non-functional p47^phox protein. This adapter molecule helps assemble the killing machinery in the cell membrane. Without it, the enzyme complex does not form correctly, leading to weakened phagocyte killing and recurrent infections.Mutation in the NCF2 gene (p67^phox deficiency)
Mutations in NCF2 disturb the p67^phox subunit, another vital activator of NADPH oxidase. Phagocytes may still engulf germs, but they cannot generate enough reactive oxygen species to damage or kill them, so infections persist.Mutation in the CYBA gene (p22^phox deficiency)
Defects in the CYBA gene lead to p22^phox loss or dysfunction, which destabilizes the whole NADPH oxidase complex. This structural failure stops effective respiratory burst, so phagocytes behave as if “blind and weak” against invading microbes.Other NADPH oxidase complex gene mutations
Some families have changes in less common genes that regulate NADPH oxidase action or location. Even if these genes are less well known, their damage can still cause the same clinical picture of congenital dysphagocytosis, showing that the killing system is multi-step and fragile.X-linked inheritance pattern in carrier mothers
In X-linked disease, mothers usually carry one faulty CYBB gene but are themselves healthy or only mildly affected. Each son has a 50% chance to inherit the faulty X chromosome and develop full disease, making family inheritance a major cause and risk factor.Autosomal recessive inheritance from both parents
For p47^phox, p67^phox, and p22^phox deficiencies, the child must receive one faulty copy from each parent. Parents are typically healthy “carriers.” If both are carriers, there is a 25% chance in each pregnancy that the child will have congenital dysphagocytosis.Consanguinity (parents related by blood)
In communities where marriages between cousins or other close relatives are common, autosomal recessive diseases like CGD are more frequent. This is because both parents may share the same rare gene variant inherited from a common ancestor.De novo (new) mutations
Sometimes a mutation appears for the first time in the affected child and is not present in the parents’ bodies. These new mutations can still cause congenital dysphagocytosis and may explain sporadic cases with no family history.Skewed X-inactivation in carrier females
In rare situations, a female carrier of an X-linked mutation may inactivate more of her normal X chromosomes than usual in blood cells. This “skewing” means many of her neutrophils carry the faulty gene and behave like CGD cells, so she can develop symptoms similar to congenital dysphagocytosis.Genetic mosaicism in parents
Some parents may carry the mutation only in some cells (mosaicism) but appear healthy. They can still pass the gene to children, causing congenital dysphagocytosis. This makes genetic counseling more complex and can lead to more than one affected child.Primary phagocyte functional disorders grouped with CGD
Congenital dysphagocytosis belongs to a group of diseases where phagocytes are present but function poorly, such as defects in chemotaxis or adhesion. These shared mechanisms show that multiple genetic pathways can lead to similar clinical patterns of recurrent infections.Family history of recurrent serious infections in childhood
A strong family pattern of severe infections, abscesses, or early deaths in siblings suggests an inherited immunodeficiency like congenital dysphagocytosis. Such a family history is a key cause clue that pushes doctors to test for CGD.Limited access to early diagnosis and treatment in certain regions
In some areas, genetic testing and specialized immune tests are not easily available. This can lead to under-diagnosis, and families may have multiple affected children before the cause is recognized. The genetic cause is present, but the health system factor delays recognition.Coexisting primary neutrophil number problems
Some patients may have both a functional defect (CGD) and issues with neutrophil numbers, such as certain congenital neutropenias. These overlapping problems can worsen infection risk and complicate the apparent cause of illness.Associated immune dysregulation or auto-inflammation genes
Some rare patients with CGD genes also carry other immune-related variants, which may cause stronger inflammatory responses, unusual granulomas, or autoimmune-like problems. These additional genes can modify how the disease caused by NADPH oxidase defects looks clinically.Environmental exposure uncovering the genetic defect
The genetic mutation is the main cause, but exposure to specific germs such as Staphylococcus aureus or Aspergillus can “unmask” the disorder. In a normal child these germs might be cleared, but in congenital dysphagocytosis they cause severe infection, revealing the underlying defect.Higher risk in males for X-linked forms
Because males have only one X chromosome, any harmful CYBB mutation will cause disease. This sex-linked genetic rule is a cause of the strong male predominance in many CGD cohorts.Worldwide distribution with clusters in certain populations
Congenital dysphagocytosis occurs in many ethnic groups, but certain communities with higher carrier frequencies or more consanguinity show more cases. Population genetics therefore contributes as a background cause for disease clustering.Lack of awareness and delayed recognition in primary care
When health workers are not familiar with primary phagocyte disorders, repeated infections may be treated one by one without searching for an inherited cause. This delay does not create the genetic defect, but it prolongs its unnoticed impact across generations.
Symptoms (15 detailed features)
People with congenital dysphagocytosis can show symptoms from infancy or early childhood, though severity varies from person to person and between different gene types.
Recurrent skin and soft-tissue abscesses
Children may develop painful lumps filled with pus in the skin, muscles, or around the anus. These abscesses are often large, slow to heal, and may keep coming back in the same or different places despite antibiotics.Frequent pneumonia and lung infections
Lung infections are common and may be severe or recurrent. Children can have repeated pneumonia, chronic cough, chest pain, or breathing difficulty, sometimes due to unusual germs that normal immune systems usually control.Lymph node swelling and lymphadenitis
Lymph nodes in the neck, armpits, or groin can swell because they are fighting infections. In congenital dysphagocytosis, these nodes may become very large, tender, and sometimes form abscesses that need drainage.Liver and spleen enlargement (hepatosplenomegaly)
The liver and spleen may enlarge because they are overworked from filtering infected blood and housing granulomas. This can cause a full feeling in the upper abdomen, discomfort, or sometimes low blood counts from hypersplenism.Liver abscesses
Deep infections in the liver are classic in CGD. They can cause fever, pain in the right upper abdomen, and abnormal liver tests. These abscesses often need prolonged antibiotics and sometimes surgery or drainage.Bone infections (osteomyelitis)
Bones can become infected, especially after small injuries or nearby skin infections. Osteomyelitis causes persistent bone pain, limping, or swelling over the affected area and can lead to bone damage if not treated early.Chronic diarrhea and gut granulomas
Some patients have ongoing diarrhea, belly pain, or poor weight gain due to granulomas and inflammation in the intestines. This can mimic inflammatory bowel disease, with similar symptoms such as blood or mucus in the stools.Urinary tract and bladder outlet problems from granulomas
Granulomas can form in the urinary tract and around the bladder outlet, causing difficulty urinating, urinary infections, or blockage symptoms. In boys, the urethra may be narrowed by granulomatous tissue.Recurrent fever without clear source
Children may have repeated high fevers that last for days or weeks. Sometimes the infection site is not obvious at first, and detailed tests are needed to find hidden abscesses or deep organ involvement.Failure to thrive and poor growth
Long-term infections and gut problems can reduce appetite and nutrient absorption. As a result, affected children may gain weight slowly, grow less in height than expected, and look smaller than their peers.Fatigue and reduced energy
Chronic illness, anemia from inflammation, and recurring fevers can leave the child tired and less active. Parents may notice less play, more resting, and difficulty keeping up with normal activities.Mouth ulcers and gum disease
Repeated sores inside the mouth, inflamed gums, and dental infections can occur because the local immune defense is weak. These sores may heal slowly and recur often, making eating painful.Skin infections at minor injury sites
Small cuts, insect bites, or injections can become exaggerated, with spreading redness, pus, and slow healing. This is because the defective phagocytes cannot quickly clear the invading germs at these entry points.Life-threatening sepsis from unusual or severe infections
Without prompt treatment, local infections can spread to the blood and cause sepsis, a dangerous condition with low blood pressure and organ failure. Patients with congenital dysphagocytosis are especially prone to severe sepsis from certain bacteria and fungi.Complications from strong inflammation and granuloma formation
The immune system tries to trap germs it cannot kill by forming granulomas. Over time, these can block hollow organs like the gut or ureters and may cause pain, obstruction, or bleeding, even when no active infection is seen.
Diagnostic tests
Diagnosis of congenital dysphagocytosis/CGD requires a mix of clinical judgment and special tests that show phagocyte killing defects and identify the underlying gene change.
Physical exam tests
1. Full general physical examination
The doctor carefully checks the child’s overall appearance, weight, height, temperature, and vital signs. They look for scars from old infections, current skin lesions, swollen lymph nodes, and signs of liver or spleen enlargement. The pattern of repeated or unusual infections on exam raises suspicion for a primary phagocyte disorder.
2. Abdominal examination for hepatosplenomegaly and tenderness
By gently feeling the abdomen, the doctor can detect an enlarged liver or spleen and areas of pain that may suggest abscesses or bowel involvement. In congenital dysphagocytosis, hepato-splenomegaly and localized tenderness are common clues to chronic deep infections or granulomas.
3. Respiratory system examination
Listening to the chest with a stethoscope and observing breathing helps detect crackles, reduced air entry, or wheezes that indicate pneumonia, lung abscess, or chronic lung damage. Repeated abnormal chest findings in a young patient prompt investigation for underlying immune defects.
4. Skin and mucosal examination
The clinician inspects the skin, mouth, and perineal area for abscesses, slow-healing wounds, ulcers, or scarring. A history and physical picture of recurrent and severe skin infections in a child strongly suggests looking for congenital dysphagocytosis or related phagocyte disorders.
Manual tests (bedside clinical assessments)
5. Detailed infection and family history taking
A careful “manual” step is the structured interview about the child’s infections, hospital stays, antibiotics used, and family members with similar conditions or early deaths. This history can reveal patterns typical for CGD, such as frequent deep abscesses and infections with specific organisms.
6. Growth chart plotting and nutritional assessment
The doctor manually plots height and weight on standard growth charts to see if the child is falling behind normal curves. Poor growth with a long history of infections and gut symptoms is a practical clue to chronic immunodeficiency like congenital dysphagocytosis.
7. Clinical scoring or checklists for primary immunodeficiency suspicion
Some centers use simple checklists (for example, “ten warning signs of primary immunodeficiency”) to manually score how likely an inherited immune problem is. High scores in children with recurrent severe infections push clinicians to order specific tests for phagocyte function.
Lab and pathological tests
8. Complete blood count (CBC) with differential
A CBC counts white blood cells, red cells, and platelets, and shows the neutrophil percentage. In congenital dysphagocytosis, neutrophil numbers may be normal or slightly altered, but the key is that they function poorly. Still, CBC helps rule out other conditions like severe neutropenia or pancytopenia.
9. Inflammatory markers (ESR and C-reactive protein)
Tests like erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are often high in active infections or inflammation. In CGD, these markers can show ongoing inflammation from hidden infections or granulomas, guiding the search for the source.
10. Blood and pus cultures for bacteria and fungi
Samples from blood or abscesses are sent to the lab to grow and identify germs. In congenital dysphagocytosis, cultures may show specific organisms known to cause problems in CGD, such as certain Staphylococcus species or Aspergillus. This pattern supports the suspected diagnosis.
11. Nitroblue tetrazolium (NBT) test
The classic NBT test measures whether neutrophils can produce superoxide radicals by changing a dye from colorless to blue. In CGD, neutrophils fail to turn the dye blue, showing that the oxidative burst is absent or severely reduced. This was a standard test before flow cytometry became common.
12. Dihydrorhodamine (DHR) flow cytometry test
The DHR test is now the preferred lab test in many centers. Neutrophils are stimulated and exposed to DHR dye, which fluoresces when oxidized. In congenital dysphagocytosis, the fluorescence signal is low or absent, clearly showing defective respiratory burst and even helping separate X-linked from autosomal forms.
13. Genetic testing panels for CGD genes
Modern DNA tests can directly sequence genes such as CYBB, NCF1, NCF2, and CYBA to find the exact mutation. Identifying the gene change confirms the diagnosis, allows carrier testing in the family, and helps in planning treatments like bone marrow transplant.
14. Bone marrow examination (aspirate and biopsy) when needed
If blood counts are abnormal or another bone marrow disease is suspected, doctors may take a small sample of bone marrow. In pure congenital dysphagocytosis, cell production may be normal, but the test helps rule out other conditions and can show chronic inflammation patterns.
15. Pathology of granulomas from biopsy
If a granuloma or mass is biopsied, the pathologist can see clusters of immune cells and signs of chronic inflammation, often without dead germs inside because they are difficult to clear. While not specific, granuloma pathology in the context of recurring infections supports the diagnosis.
Electrodiagnostic / electronic monitoring tests
16. Pulse oximetry for oxygen saturation
A small electronic sensor on the finger or toe measures blood oxygen levels. In congenital dysphagocytosis, this bedside test is important during pneumonia or sepsis to see how serious lung or systemic infection is and whether extra oxygen or intensive care is needed.
17. Lung function tests with electronic spirometry (when age-appropriate)
Older children may blow into an electronic spirometer to assess lung capacity and airflow. Repeated lung infections in congenital dysphagocytosis can cause chronic damage, and spirometry helps monitor long-term respiratory health and guide rehabilitation.
Imaging tests
18. Chest X-ray
A basic X-ray picture of the chest can show pneumonia, lung abscesses, scarring, or enlarged lymph nodes. In a child with recurrent or unusual lung shadows, a chest X-ray is often the first imaging step that raises suspicion for an underlying immunodeficiency.
19. Ultrasound of abdomen and other organs
Ultrasound uses sound waves to view organs like the liver, spleen, kidneys, and lymph nodes. It is painless and radiation-free. In congenital dysphagocytosis, ultrasound can reveal liver abscesses, enlarged organs, or granuloma masses that may not be obvious on physical exam.
20. CT or MRI scans for detailed imaging
Computed tomography (CT) or magnetic resonance imaging (MRI) give detailed pictures of organs and tissues. These scans are used to define the size and location of abscesses, granulomas, lung damage, or bowel complications, and to plan surgery or drainage if needed. In children with CGD, such imaging is vital for safe and targeted treatment of deep infections.
Non-Pharmacological Treatments
1. Infection-prevention education
Education is the base of treatment. The healthcare team teaches the family what CGD is, which germs are most dangerous, and which everyday places are risky, such as farm soil, compost, construction dust and stagnant water.[1] They learn to spot early signs of infection (fever, cough, abdominal pain, skin redness) and to seek help quickly. The purpose is to reduce exposure and make sure infections are treated early. This works because when patients and caregivers understand the disease, they can change habits and call the doctor long before illness becomes severe.[2] [1]
2. Strict personal hygiene routines
Regular hand-washing with soap, showering, nail care and careful shaving help remove germs from the skin surface before they enter the body.[1] Patients are often advised to avoid sharing razors, towels or toothbrushes. The purpose is to lower the number of bacteria on the skin and in the mouth. Mechanistically, fewer germs on the skin and mucosa means fewer chances for cuts, scrapes or minor mouth sores to become serious infections, which is especially important when phagocytes cannot kill bacteria well.[2] [2]
3. Environmental control at home
Families are encouraged to keep the house dry, clean and well-ventilated, use mold-resistant paint in damp areas, fix leaks quickly and avoid indoor plants with damp soil.[1] HEPA air filters may be used in some homes. The purpose is to reduce exposure to mold spores and environmental fungi that are very dangerous for CGD. This helps because lower mold and dust levels reduce the chance that inhaled organisms like Aspergillus will settle in the lungs and cause life-threatening infections.[2] [3]
4. Safe food and water practices
Non-drug care includes avoiding raw or undercooked meat, raw eggs, unpasteurized milk, unwashed fruits and vegetables, and untreated water.[1] Food is cooked thoroughly and leftovers stored safely. The purpose is to prevent gastrointestinal infections from bacteria like Salmonella or Campylobacter. Mechanistically, proper cooking kills many pathogens before they enter the body, which is crucial when the gut immune defenses are weaker because of faulty phagocyte killing.[2] [4]
5. Vaccination planning (with specialist guidance)
Patients with congenital dysphagocytosis usually receive standard inactivated vaccines (such as influenza and pneumococcal vaccines), but live vaccines may be avoided or timed carefully depending on local guidelines.[1] The purpose is to prevent severe infections that vaccines can safely block. The mechanism is the same as for other people: vaccines “train” the immune system to recognize germs quickly. Even though phagocytes are abnormal, antibody and T-cell responses can still give important protection.[2] [5]
6. Regular dental and oral care
Frequent dental check-ups, daily brushing and flossing, and quick treatment of cavities and gum disease help prevent oral infections.[1] The purpose is to stop small mouth problems from becoming deep infections that can spread to the blood or lungs. Good oral hygiene reduces bacterial load in the mouth, so phagocytes have fewer germs to fight, lowering the risk of abscesses or sinus infections in CGD.[2] [6]
7. Skin protection and wound care
Patients are advised to avoid barefoot walking outdoors, to wear gloves in the kitchen or garden (if gardening is allowed at all), and to immediately wash and cover cuts.[1] The purpose is to stop bacteria from entering through tiny skin breaks. Cleansing, topical antiseptics and sterile dressings lower bacterial counts around the wound, so even weak phagocytes can keep the infection under control and reduce abscess formation.[2] [7]
8. Avoidance or modification of high-risk activities
Activities like gardening, mowing, raking leaves, building demolition and cave visits bring heavy exposure to soil, dust and bird or bat droppings.[1] Many specialists advise avoiding these, or using strong masks and protective clothing. The purpose is to reduce inhalation of dangerous fungi such as Aspergillus and Histoplasma. Mechanistically, fewer spores inhaled means fewer chances for deep lung infections that phagocytes in CGD cannot clear.[2] [8]
9. Tailored physical activity and rehabilitation
Gentle regular exercise keeps muscles and lungs strong, improves circulation and supports mental health.[1] The purpose is to maintain stamina so the body can better handle infections and recover from hospital stays. Exercise improves lung expansion and mucus clearance, helping to move bacteria and mucus out of the airways and decreasing the chance of pneumonia becoming severe.[2] [9]
10. Nutritional counseling and adequate calories
A dietitian often helps plan a nutrient-dense diet with enough protein, calories, vitamins and minerals.[1] Children with CGD may have poor appetite during repeated illness or gut inflammation. The purpose is to support growth, wound healing and immune cell function. Good nutrition supplies amino acids, vitamins and trace elements needed for antibody production and cell repair, which partly compensates for weak phagocyte killing.[2] [10]
11. Psychological support and coping skills
Living with a chronic, infection-prone disease is stressful for patients and families. Counseling, support groups and school-based support can help.[1] The purpose is to reduce anxiety, depression and treatment fatigue. Better mental health improves treatment adherence, sleep and self-care behaviors, which indirectly lowers infection risk and improves long-term outcomes.[2] [11]
12. Family genetic counseling
Because congenital dysphagocytosis/CGD is inherited, families are often offered genetic counseling and carrier testing.[1] The purpose is to explain recurrence risks, plan future pregnancies and identify relatives who may have mild, unrecognized disease. Mechanistically, early identification of affected family members allows earlier monitoring and infection prevention, which can be life-saving.[2] [12]
13. Home infection-control routines
Cleaning frequently touched surfaces, careful food storage and sometimes using separate towels or utensils during active infections are simple home measures.[1] The purpose is to cut down on household transmission of respiratory and gastrointestinal germs. Lower exposure at home means fewer infections overall, which is key when each infection can become severe or form granulomas.[2] [13]
14. School and workplace adjustments
Children and adults with CGD may need flexible school attendance, online learning options during outbreaks, or work roles that avoid dusty, dirty or crowded environments.[1] The purpose is to keep education and employment on track while still protecting health. Mechanistically, reducing time in high-exposure environments lowers infection risk but still supports social and cognitive development.[2] [14]
15. Travel planning and emergency plans
Before travel, patients discuss routes, vaccines, needed medications and nearby hospitals with their medical team.[1] An emergency letter explaining their diagnosis and usual antibiotics is very helpful. The purpose is to prevent delays if they become sick away from home. This works because early, appropriate antibiotics are critical to stop infections from progressing in CGD.[2] [15]
16. Regular specialist follow-up
Routine visits with an immunologist or hematologist allow monitoring of growth, liver and lung health, inflammatory bowel disease and drug side effects.[1] The purpose is to catch complications such as strictures, abscesses or hypertension early. Mechanistically, early imaging, lab tests and stool tests guide interventions before organs are seriously damaged.[2] [16]
17. Early treatment pathways for fever
Many centers give families a “fever plan” that tells them exactly when to call, when to go to hospital and sometimes to start a backup oral antibiotic if instructed.[1] The purpose is to shorten the time between first fever and effective treatment. Fast action is important because bacterial and fungal infections can spread quickly in CGD when phagocyte killing is weak.[2] [17]
18. Multidisciplinary team care
Non-drug care includes coordination between immunologists, infectious-disease doctors, surgeons, gastroenterologists, psychologists, nurses and dietitians.[1] The purpose is to manage the whole person, not only infections. A team approach improves consistency, avoids conflicting advice and ensures that granulomas, colitis, lung issues and psychosocial problems are all addressed in a balanced way.[2] [18]
19. Education on medication adherence
Teaching patients why they must take prophylactic antibiotics and antifungals every day, even when they feel well, is vital.[1] The purpose is to keep drug levels steady in the body to prevent infections. Steady levels of these medicines act like a constant “protective shield,” which is especially important because their phagocytes cannot quickly catch up if an infection begins.[2] [19]
20. Shared decision-making about curative options
Families are counseled about hematopoietic stem cell transplantation (HSCT) and, in research settings, gene therapy.[1] The purpose is to weigh the benefits of a possible cure against the serious risks of transplant. Mechanistically, transplant replaces defective bone-marrow stem cells with healthy donor cells so new phagocytes have a normal oxidative burst and can kill bacteria and fungi effectively.[2] [20]
Drug Treatments
Important: All doses below are examples only. Real doses and schedules must be chosen by a specialist, especially in children. Never change or start medicines without your doctor. [1]
1. Trimethoprim–sulfamethoxazole (TMP-SMX / Bactrim)
TMP-SMX is a combination antibiotic from the sulfonamide class, usually taken once or twice daily for long-term bacterial prophylaxis.[1] A common prophylactic dose is around 5 mg/kg/day of the trimethoprim part, up to about one double-strength tablet daily in adults, adjusted by the doctor.[2] Its main purpose is to prevent bacterial infections from organisms such as Staphylococcus aureus and some Gram-negative bacteria, which are common in CGD.[3] It works by blocking bacterial folate synthesis at two steps, which slows DNA production and stops bacteria growing.[4] Possible side effects include rash, sun sensitivity, low blood counts, high potassium and rare serious skin reactions.[5] [1]
2. Itraconazole (Sporanox)
Itraconazole is a triazole antifungal drug taken once or twice daily, often as a solution or capsule, to prevent fungal infections in CGD.[1] Dosing depends on weight, liver function and blood levels, and is carefully monitored by specialists. The purpose is to cut down dangerous fungal infections such as invasive Aspergillus.[2] Itraconazole inhibits fungal cytochrome P450 enzymes that make ergosterol, a key cell-membrane component, so the fungi cannot grow properly.[3] Side effects include liver enzyme rise, heart failure risk in some patients, drug–drug interactions and stomach upset.[4] [2]
3. Posaconazole (Noxafil)
Posaconazole is a newer triazole antifungal used in some centers as prophylaxis or treatment for resistant fungal disease.[1] It may be given as oral suspension, delayed-release tablets or IV infusion, with dosing based on age and weight.[2] The purpose is similar to itraconazole: prevent or treat invasive mold infections in high-risk CGD patients.[3] Posaconazole blocks ergosterol synthesis in fungal cell membranes, but has activity against some fungi that may be less sensitive to older azoles.[4] Side effects can include liver test abnormalities, nausea, headache and interactions with other drugs that use liver enzymes.[5] [3]
4. Voriconazole
Voriconazole is another triazole antifungal often used to treat active, serious Aspergillus infections in CGD rather than routine prophylaxis.[1] It can be given orally or by IV, with doses adjusted using blood levels, liver tests and age. The purpose is to treat life-threatening fungal pneumonia or deep tissue infections. Mechanistically, it also blocks fungal ergosterol synthesis, but its spectrum covers many mold species.[2] Side effects include liver toxicity, visual disturbances, skin photosensitivity and drug interactions, so it must be used under close supervision.[3] [4]
5. Amphotericin B
Amphotericin B is a powerful IV antifungal from the polyene class, reserved for severe, difficult fungal infections in CGD.[1] Different formulations (conventional and liposomal) have different dosing and side-effect profiles. The purpose is to quickly control life-threatening infections, often at the start of therapy before switching to an oral azole.[2] Amphotericin B binds to ergosterol in fungal cell membranes, making pores that cause cell leakage and death.[3] Side effects can be serious: kidney damage, low potassium and magnesium, fever and chills during infusion, so it is used in hospital with careful monitoring.[4] [5]
6. Piperacillin–tazobactam
This IV combination of a broad-spectrum penicillin (piperacillin) and a β-lactamase inhibitor (tazobactam) is often used for severe bacterial infections like liver or lung abscesses.[1] It is usually given every 6–8 hours in hospital, with doses adjusted for kidney function. The purpose is to cover a wide range of Gram-positive and Gram-negative bacteria while cultures are pending.[2] Piperacillin blocks bacterial cell-wall synthesis, while tazobactam protects it from breakdown by bacterial enzymes.[3] Side effects include allergic reactions, diarrhea and changes in kidney function or blood counts.[4] [6]
7. Ceftriaxone
Ceftriaxone is a third-generation cephalosporin antibiotic given once or twice daily by IV or IM injection.[1] In CGD it may be used for serious infections such as sepsis or pneumonia, often combined with other drugs depending on local patterns. Its purpose is to treat many Gram-negative and some Gram-positive bacteria.[2] It works by interfering with bacterial cell-wall synthesis. Side effects can include allergic reactions, diarrhea, gallbladder sludge and rarely changes in blood counts.[3] [7]
8. Vancomycin
Vancomycin is an IV glycopeptide antibiotic that targets Gram-positive bacteria like MRSA.[1] It is used when resistant staphylococcal or streptococcal infections are suspected in CGD. Dosing depends on body weight and kidney function, and blood levels are often checked. The purpose is to reliably cover serious Gram-positive infections such as sepsis or osteomyelitis.[2] Vancomycin blocks cell-wall building in bacteria. Side effects include kidney toxicity, hearing problems at high levels and “red man” flushing if infused too fast.[3] [8]
9. Meropenem
Meropenem is a broad-spectrum carbapenem antibiotic used IV for very severe or resistant bacterial infections.[1] In CGD, it may be chosen for abdominal sepsis or when other antibiotics fail. The purpose is to provide powerful coverage while cultures guide narrower choices.[2] Meropenem inhibits bacterial cell-wall synthesis and resists many β-lactamases. Side effects include diarrhea, allergic reactions and, rarely, seizures at very high doses.[3] [9]
10. Linezolid
Linezolid is an oxazolidinone antibiotic that treats resistant Gram-positive bacteria, including MRSA and some enterococci.[1] It can be given orally or IV, with typical dosing every 12 hours short-term. The purpose in CGD is to manage difficult soft-tissue or bone infections caused by resistant organisms.[2] It works by blocking bacterial protein synthesis at the ribosome. Side effects with longer use include low platelets, anemia, neuropathy and interactions with some antidepressants.[3] [10]
11. Ciprofloxacin or levofloxacin
These fluoroquinolone antibiotics are sometimes used orally or IV for specific Gram-negative infections.[1] They are dosed once or twice daily depending on the drug and kidney function. The purpose is targeted treatment of bacteria like Pseudomonas when indicated by cultures. They work by blocking bacterial DNA gyrase and topoisomerase, stopping DNA replication.[2] Side effects can include tendon problems, nerve pain, mood changes and QT-interval prolongation, so they are used carefully, especially in children.[3] [11]
12. Interferon gamma-1b (Actimmune)
Interferon gamma-1b is a manufactured version of a natural immune signaling protein.[1] It is the only drug with a specific FDA indication to reduce the frequency and severity of serious infections in CGD.[2] It is given as a subcutaneous injection, often three times per week, at a dose based on body surface area. The purpose is to boost phagocyte function and reduce serious infections over time.[3] Its mechanism is complex but includes increasing nitric-oxide production and improving the ability of phagocytes to kill bacteria and fungi.[4] Common side effects are flu-like symptoms (fever, chills, fatigue), injection-site redness and mild liver enzyme changes.[5] [12]
13. Corticosteroids (for inflammatory complications)
Prednisone or similar steroids are sometimes used short-term during severe inflammatory complications, such as obstructing granulomas or CGD colitis, always in combination with good infection coverage.[1] Doses and tapers vary widely. The purpose is to reduce harmful inflammation, swelling and pain that can damage organs or block bowel or urinary flow.[2] Steroids reduce activity of many immune cells and inflammatory mediators. Side effects include weight gain, mood changes, high blood sugar, bone thinning and higher infection risk, so they are used carefully.[3] [13]
14. Mesalamine or budesonide (for CGD colitis)
Some patients develop inflammatory bowel disease that looks similar to Crohn’s disease.[1] Oral or topical gut-targeted drugs like mesalamine or budesonide may be used, often alongside antibiotics. The purpose is to reduce gut inflammation, pain and diarrhea.[2] Mesalamine acts locally on bowel mucosa to reduce inflammatory mediators; budesonide is a steroid with strong first-pass liver metabolism, giving more local than systemic effect.[3] Side effects can include headache, nausea or mild steroid effects.[4] [14]
15. Intravenous immunoglobulin (IVIG)
IVIG is a concentrated antibody solution from healthy donors, given by IV over several hours.[1] It is used in some CGD patients with recurrent infections or associated antibody problems. The purpose is to provide broad antibody support and modulate immune responses.[2] IVIG works by supplying ready-made antibodies and altering immune cell signaling. Side effects include headache, infusion reactions and rarely kidney problems or blood clots.[3] [15]
16. Filgrastim (G-CSF)
Filgrastim is a granulocyte colony-stimulating factor that can increase neutrophil numbers.[1] It may be used short-term during severe infections or before procedures in selected patients. The purpose is to raise neutrophil counts so more phagocytes are available to fight infection, even though their killing function is still abnormal.[2] It acts on bone marrow stem cells to speed neutrophil production and release.[3] Side effects include bone pain, spleen enlargement and, rarely, splenic rupture.[4] [16]
17. Caspofungin or other echinocandins
Echinocandin antifungals (like caspofungin) are used IV for serious Candida or Aspergillus infections.[1] In CGD they may be combined with azoles or amphotericin for difficult cases. The purpose is to provide another mechanism against fungi, especially when azole resistance or intolerance occurs.[2] They work by blocking fungal cell-wall β-glucan synthesis. Side effects include liver enzyme elevations, fever and infusion reactions.[3] [17]
18. Metronidazole
Metronidazole is an antibiotic effective against anaerobic bacteria and some parasites, sometimes used in CGD colitis or abdominal infections.[1] It is taken orally or IV several times a day, according to weight. The purpose is to target gut bacteria that thrive without oxygen.[2] It damages microbial DNA inside susceptible organisms. Side effects can include metallic taste, nausea and peripheral neuropathy with long use; alcohol must be avoided during therapy.[3] [18]
19. Topical antiseptic agents (e.g., chlorhexidine)
While not “systemic drugs,” topical antiseptics are used on skin and wounds to lower bacterial load.[1] The purpose is to reduce minor skin infections and protect surgical or biopsy sites. They work by disrupting bacterial cell membranes and proteins at the local surface, which is helpful when deeper immunity is weak.[2] Side effects are usually mild skin irritation or allergy.[3] [19]
20. Acetaminophen and supportive medicines
Simple medicines like acetaminophen (paracetamol) are used to control fever and pain, making it easier for patients to rest and drink fluids.[1] The purpose is comfort and improved ability to continue antibiotics and daily life. Acetaminophen works mainly in the brain to reduce pain and fever signals. Side effects are rare at correct doses, but overdose can harm the liver, so maximum daily doses must never be exceeded.[2] [20]
Dietary Molecular Supplements
Evidence for supplements in congenital dysphagocytosis/CGD is limited. They do not replace standard medicines. Always discuss with the treating specialist before starting any supplement. [1]
Vitamin D – Supports bone health and modulates immune responses; many patients with chronic illness have low levels.[1] Typical doses range from 400–1,000 IU/day in children and 800–2,000 IU/day or more in adults under medical guidance. It helps regulate T-cells and innate immunity and may slightly improve resistance to respiratory infections.[2] [1]
Vitamin C – An antioxidant that helps protect cells from oxidative damage and supports collagen formation and wound healing.[1] Often taken in doses like 100–500 mg/day, adjusted to avoid stomach upset. It participates in many enzymatic reactions and may support barrier function in skin and mucosa, which indirectly helps block infection entry.[2] [2]
Zinc – An essential trace element important for immune cell development and enzyme function.[1] Typical supplemental doses might be 5–20 mg/day, but total intake should not exceed recommended upper limits without medical supervision. Zinc affects T-cell and B-cell function and skin healing, which may help reduce infection risk and improve wound repair.[2] [3]
Selenium – Another trace mineral that supports antioxidant defenses (via glutathione peroxidase) and thyroid function.[1] Supplement doses are usually around 50–100 micrograms/day. Adequate selenium helps limit oxidative stress and can modulate immune responses, which may be useful in chronic inflammatory states.[2] [4]
Omega-3 fatty acids (fish oil) – Omega-3s like EPA and DHA have anti-inflammatory effects.[1] Typical doses might be 250–1,000 mg/day of combined EPA/DHA. They work by shifting the balance of lipid mediators from pro-inflammatory to more resolving types, which can help calm chronic inflammation in vessels and gut while maintaining host defense.[2] [5]
Probiotics (with care) – Certain probiotic strains may support gut barrier function and reduce antibiotic-associated diarrhea.[1] Doses and strains vary widely. They act by competing with harmful bacteria, producing short-chain fatty acids and interacting with gut immune cells. In CGD, probiotics must be chosen carefully because rare bloodstream infections from probiotic organisms have been reported in immunocompromised patients, so specialist advice is essential.[2] [6]
Folate and vitamin B12 – These B-vitamins are needed for red blood cell production and DNA synthesis.[1] Supplementation is guided by blood levels, often a standard multivitamin dose. Adequate folate/B12 supports bone-marrow health, which is important when neutrophil turnover may be high during infections.[2] [7]
Iron (only if deficient) – Iron is crucial for hemoglobin and many enzymes, but supplementing iron can feed some bacteria, so it is used only when clear deficiency is proven.[1] Dose and form are chosen by the doctor. Correcting iron deficiency improves energy and oxygen delivery to tissues, but must be balanced against any infection risk.[2] [8]
N-acetylcysteine (NAC) – NAC is an antioxidant precursor of glutathione and a mucolytic.[1] It may be used to thin airway secretions and support antioxidant defenses at doses such as 600 mg/day or more in adults, under supervision. It helps break disulfide bonds in mucus, making it easier to cough up, and boosts glutathione levels, which may protect cells from oxidative stress.[2] [9]
Curcumin (turmeric extract) – Curcumin has anti-inflammatory and antioxidant actions.[1] Supplements often provide 250–1,000 mg/day with absorption enhancers like piperine, but data in CGD are limited. It reduces activity of NF-κB and other inflammatory pathways, which may help with chronic inflammation such as colitis, but must not replace standard medical therapy.[2] [10]
Immunity-Boosting, Regenerative and Stem Cell–Related Therapies
Interferon gamma-1b – Already described above, this is the main immune-boosting drug specifically approved to reduce serious infections in CGD.[1] It improves phagocyte function and has long-term safety data when used with careful monitoring.[2] [1]
Granulocyte colony-stimulating factor (G-CSF, filgrastim) – Used to raise neutrophil numbers in selected situations, such as severe infections or surgery.[1] By stimulating bone-marrow stem cells to make more neutrophils, it temporarily increases the number of phagocytes available, even though each cell’s oxidative burst is still imperfect.[2] [2]
Granulocyte–macrophage colony-stimulating factor (GM-CSF) – GM-CSF (sargramostim) can enhance function of several myeloid cells.[1] In some experimental or rescue situations it is used to support host defense. It acts on progenitor cells and mature phagocytes, boosting their numbers and activity, but evidence in CGD is more limited than for G-CSF.[2] [3]
Hematopoietic stem cell transplantation (HSCT) – HSCT is not a pill but a major procedure using donor stem cells from bone marrow, peripheral blood or cord blood.[1] After conditioning chemotherapy, donor cells are infused and travel to the marrow, where they can form new immune cells with a normal NADPH oxidase system. HSCT can be curative but carries significant risks, including graft-versus-host disease and infections, so it is carefully weighed by experts.[2] [4]
Gene-therapy using autologous stem cells (research setting)
In experimental studies, a patient’s own stem cells are collected, corrected with a viral vector or gene-editing method, and then returned after conditioning therapy.[1] The goal is to give the patient new phagocytes that can perform normal oxidative bursts without needing a donor.[2] Early trials in CGD have shown promising results but are still being refined and are not yet standard care everywhere.[3] [5]Granulocyte transfusions
In selected life-threatening infections that do not respond to drugs, some centers use donor granulocyte transfusions as a temporary immune boost.[1] Transfused neutrophils can provide short-term killing capacity while antibiotics and antifungals act. However, repeated transfusions can cause immune reactions and complicate later HSCT, so they are reserved for special situations.[2] [6]
Surgeries and Procedures
Abscess drainage – Deep abscesses in liver, lung or soft tissue often need surgical or radiologic drainage.[1] Removing pus lowers the number of germs and relieves pressure, allowing antibiotics to work better and protecting surrounding organs.[2]
Bowel surgery for strictures or obstruction – Chronic granulomas in the gut can cause narrowing or blockage.[1] Surgeons may perform resection of a short segment or a stricture-plasty to open the blockage. The procedure is done to relieve obstruction, pain and malnutrition when medical therapy is not enough.[2]
Lung surgery (segment or lobectomy) – Very damaged localized lung segments from repeated infections may sometimes be removed.[1] The aim is to remove a persistent infection focus or cavity that does not respond to medicines, improving breathing and preventing ongoing seeding of bacteria.[2]
Surgical management of urinary or biliary obstruction – Granulomas can narrow urinary tract or bile ducts.[1] Procedures such as stenting, dilation or limited resection relieve obstruction, protect kidneys or liver and improve symptoms.[2]
Central venous catheter placement and removal – Many CGD patients need long IV antibiotic courses through central lines.[1] Insertion is done in a sterile way, and infected or blocked catheters are removed. Proper line care prevents bloodstream infections and ensures reliable access for life-saving treatments.[2]
Prevention Tips
Take prophylactic antibiotics and antifungals exactly as prescribed, every day.[1]
Follow strict hand-washing and daily hygiene routines.[2]
Avoid gardening, compost, farm work, construction dust and caves unless your specialist says it is safe and good protective gear is used.[3]
Keep vaccinations up to date, following the plan from your immunology team.[4]
Maintain regular dental visits and treat mouth problems early.[5]
Store and cook food safely; avoid raw meats, raw eggs and unpasteurized products.[6]
Have a clear “fever plan” and seek urgent care for fever, breathing problems, severe pain or sudden illness.[7]
Attend all specialist check-ups and monitoring tests.[8]
Plan travel with your team and carry a medical summary and emergency contacts.[9]
Protect mental health with support, counseling and open communication in the family.[10]
When to See Doctors
People with congenital dysphagocytosis/CGD should contact a doctor immediately (often the emergency department) if they have fever, chills, new cough, trouble breathing, chest pain, severe abdominal pain, painful urination, blood in stool, rapid swelling, very painful skin lumps, or sudden change in general condition.[1] Even “small” infections can become serious quickly, so waiting at home is risky. They should also call their specialist if they miss doses of prophylactic medicines, notice yellow eyes, dark urine, new severe headaches, vision changes or strong side effects from drugs.[2] Regularly scheduled visits with the immunology team are important even when they feel well, to adjust medicines and screen for complications.[3] [1]
What to Eat and What to Avoid
Eat: well-cooked lean meats, poultry and fish to provide protein for healing and immune cells.[1]
Eat: a variety of cooked vegetables and peeled fruits for vitamins, but wash and cook them properly.[2]
Eat: whole grains, beans and lentils that are well cooked to give fiber and energy.[3]
Eat: yogurt or fermented dairy products that are pasteurized, if allowed by your doctor, to support gut health.[4]
Eat: small, frequent meals and drink plenty of safe, treated water to maintain hydration and nutrition during illness.[5]
Avoid: raw or undercooked meat, fish, shellfish and eggs, because they may carry harmful bacteria.[6]
Avoid: unpasteurized milk, cheeses and juices, which can contain dangerous germs.[7]
Avoid: foods from street stalls or buffets that may have stayed at room temperature for long periods.[8]
Avoid: high-dose “immune-boosting” herbal mixtures without medical advice, as they may interact with antifungal or other drugs.[9]
Avoid: drinking untreated well water or surface water; always use boiled or safely filtered water.[10]
Frequently Asked Questions
1. Is congenital dysphagocytosis the same as chronic granulomatous disease?
Yes. Congenital dysphagocytosis is an older name used in early reports for what is now called chronic granulomatous disease (CGD), a phagocyte bactericidal dysfunction with recurrent infections and granuloma formation.[1] [1]
2. Can this disease be cured?
Some patients can be functionally cured with hematopoietic stem cell transplantation, and gene-therapy trials are very promising, but these treatments carry serious risks and are not suitable for everyone.[2] Many people instead use lifelong prophylactic medicines and careful lifestyle changes to control the disease.[3] [2]
3. Why are antibiotics needed even when I feel well?
Daily prophylactic antibiotics such as TMP-SMX act like a shield, keeping bacterial counts low so serious infections are less likely to start.[1] Because phagocytes in CGD have trouble killing bacteria, waiting until symptoms appear can be dangerous.[2] [3]
4. Do antifungal medicines have to be taken for life?
Many guidelines recommend long-term antifungal prophylaxis, especially in high-risk patients, but exact duration is individualized.[1] Your doctor balances infection risk, side effects and new clinical data at each visit.[2] [4]
5. Is interferon gamma-1b safe for children?
Interferon gamma-1b has been studied in children with CGD and is approved to reduce serious infections, with flu-like symptoms as the most common side effect.[1] Long-term studies show it can lower infection rates when used correctly and monitored regularly.[2] [5]
6. Does having CGD mean I will always be sick?
No. Many people with CGD lead relatively active lives, attend school and work and have families.[1] However, they need careful prevention, quick treatment of infections and regular specialist follow-up. Good care has greatly improved survival compared with older reports.[2] [6]
7. Can I play sports?
Light to moderate sports are often encouraged, as long as they are safe and not in high-risk environments like muddy fields or dusty barns.[1] Your care team can help choose activities that protect you from injury and infection while keeping you strong and happy.[2] [7]
8. Are pets allowed?
Some experts prefer that CGD patients avoid pets, especially reptiles, rodents and young animals that may carry more germs, but rules vary.[1] If families keep pets, strict hygiene and vet check-ups are important. Your specialist can give personalized advice.[2] [8]
9. Will my children also have this disease?
Risk depends on whether the mutation is X-linked or autosomal recessive, and whether you are a carrier.[1] Genetic counseling and testing help estimate the chance that future children will have CGD or be carriers and allow early diagnosis.[2] [9]
10. Is it safe to travel abroad?
Travel can be possible with careful planning: vaccines, extra medicines, insurance and knowing nearby hospitals.[1] High-risk destinations with poor hygiene or limited medical care may be discouraged. Always plan trips with your care team.[2] [10]
11. What happens if I miss a dose of my prophylactic medicine?
If you forget a dose, usually you take it when you remember unless it is almost time for the next dose, but your own doctor’s instructions should be followed.[1] Repeated missed doses weaken the protective barrier and increase infection risk, so talk to your team if you struggle with adherence.[2] [11]
12. Can diet alone control congenital dysphagocytosis?
No. A healthy diet supports general health and healing, but it cannot correct the underlying phagocyte defect.[1] Lifelong medical treatment and infection-prevention strategies remain essential, and supplements should only be used as an add-on to, not a replacement for, standard care.[2] [12]
13. Are live vaccines always forbidden?
Not always, but they must be considered very carefully by immunology and infectious-disease specialists.[1] Some live vaccines may be avoided, delayed or replaced depending on local policies and your overall immune status. Never receive live vaccines without discussing them with your specialist.[2] [13]
14. How is congenital dysphagocytosis diagnosed?
Diagnosis usually includes blood tests of neutrophil function (such as dihydrorhodamine [DHR] flow cytometry) and genetic testing to identify the mutation.[1] A history of recurrent, unusual infections and granulomas also raises suspicion.[2] [14]
15. What is the most important thing families can do?
The single most important thing is to build a strong partnership with an experienced immunology team, follow prophylactic regimens exactly and act quickly for any signs of infection.[1] Combined with good hygiene, nutrition and emotional support, this gives children and adults with congenital dysphagocytosis the best chance for a long, active life.[2] [15]
