Autosomal recessive infantile polycystic kidney disease—most often called ARPKD—is a rare genetic condition. It usually shows up before birth or in the first months of life. Tiny fluid-filled spaces form in the kidney’s collecting ducts, so the kidneys become large and very dense on ultrasound. Most children also develop congenital hepatic fibrosis (scarring in the liver and bile ducts). The single root cause is inheriting two non-working copies of the PKHD1 gene (one from each parent). That gene makes a protein called fibrocystin (polyductin), which helps the kidney and bile ducts form and function correctly; when it fails, the ducts dilate and scar. MedlinePlus+3NCBI+3NIDDK+3
ARPKD is a rare genetic disease that babies can have before or right after birth. It is caused most often by changes (variants) in a gene called PKHD1. The kidneys develop many tiny cysts and become large and stiff. The liver also develops congenital hepatic fibrosis, which can lead to portal hypertension (high pressure in the portal vein), enlarged spleen, and problems like enlarged veins in the esophagus (varices) or infections of the bile ducts (cholangitis). Many babies have trouble breathing at birth because the big kidneys and low amniotic fluid can cause under-developed lungs; many children later develop high blood pressure and chronic kidney disease that can progress to kidney failure. Care is supportive and often includes blood-pressure control, infection care, nutrition, dialysis, and sometimes kidney or combined liver-kidney transplant. Frontiers+3NCBI+3NCBI+3

Types
ARPKD does not have different “causes,” but clinicians often sort cases by age at presentation and by organ problems. These “types” help guide care and expectations:
Perinatal/Neonatal-onset ARPKD
Detected in late pregnancy or at birth. Ultrasound shows bilaterally enlarged, echogenic kidneys; babies may have breathing trouble from lung under-development caused by severe low amniotic fluid (pulmonary hypoplasia). NCBI+2Radiopaedia+2Infant-onset ARPKD
Presents in the first year with large kidneys, high blood pressure, feeding problems, and gradually rising creatinine. NCBIChildhood-onset ARPKD
Kidney function can be variable; liver disease (congenital hepatic fibrosis) and portal hypertension become more obvious (big spleen, enlarged abdominal veins, or variceal bleeding). PubMedLiver-predominant ARPKD
Some children keep better kidney function for years but develop bile-duct abnormalities (Caroli spectrum), jaundice, itching, and portal hypertension. NCBI
Causes
Important note: The fundamental cause is the same in all patients—biallelic pathogenic variants in PKHD1. The items below explain the genetics, the kinds of gene changes, and the biological mechanisms that produce the disease features and their severity.
Biallelic PKHD1 variants
Two harmful variants—one from each parent—are required (autosomal recessive). NCBI+1Loss of fibrocystin (polyductin) function
Fibrocystin helps tubules and bile ducts form; without it, ducts dilate and fail. MedlinePlus+1Missense variants
Single-amino-acid changes can reduce protein activity and often relate to milder or later disease. (Genotype-phenotype patterns are described in GeneReviews.) NCBITruncating (nonsense/frameshift) variants
These usually remove most protein function and are often linked to earlier, more severe disease. NCBICompound heterozygosity
Many children inherit two different faulty variants (one from each parent); the combination shapes severity. NCBISplice-site variants
Changes at intron–exon boundaries disrupt correct RNA processing and lower functional protein. PubMedLarge gene size and multiple transcripts
PKHD1 is huge and complex, which helps explain the many possible disease-causing changes. PubMedPrimary cilium dysfunction (ciliopathy)

Diagnostic tests
A) Physical-exam–based assessments (bedside)
Abdominal inspection and gentle palpation

Non-pharmacological (therapy & other) treatments
Neonatal intensive support (breathing and fluids).
Newborns with ARPKD can have breathing trouble from small lungs and huge kidneys. In the NICU, gentle ventilation, oxygen, and careful fluids help the baby breathe and keep blood pressure and salts stable. Purpose: keep oxygen and circulation safe in the first days of life. Mechanism: ventilators support the lungs while careful fluids prevent overload that can worsen lung function and kidney stress. NCBI+1Regular blood-pressure checks at home and clinic.
High blood pressure (hypertension) starts early and silently damages kidneys, heart, and eyes. Purpose: catch and treat high readings quickly. Mechanism: frequent cuff readings guide salt restriction, medicine timing, and clinic decisions to limit kidney scarring over time. NCBILow-salt eating pattern.
Salt pulls water into the bloodstream and raises pressure. Purpose: help blood-pressure control and reduce swelling. Mechanism: lowering daily sodium reduces fluid retention and the amount of pressure the kidneys and vessels face. (Works together with medicines when needed.) NCBIGrowth-focused nutrition with a pediatric renal dietitian.
Many infants and children with ARPKD struggle to grow. Purpose: protect growth and brain development. Mechanism: tailored calories, protein, and minerals (calcium/phosphate balance) support growth while avoiding excess salt, potassium, or phosphorus that kidneys cannot clear.

Poor appetite or reflux can limit intake. Purpose: deliver enough calories safely. Mechanism: tubes bypass the need for perfect oral intake and allow continuous or overnight feeds to meet goals without stressing the child. NCBIVaccination on time (plus liver-disease-focused vaccines).
Children with chronic kidney and liver disease are vulnerable to infections. Purpose: prevent severe infections (RSV, flu, pneumococcus, hepatitis A/B where appropriate). Mechanism: immune priming reduces the chance of hospitalizations that can worsen kidney/liver function. NCBIInfection-prevention hygiene and early fever plans.
Portal hypertension and bile-duct changes increase cholangitis risk; urinary tract infections can also occur. Purpose: catch infections early. Mechanism: hand hygiene, prompt urine tests for fever, and rapid evaluation for belly pain/fever aim to stop sepsis or bile-duct infection quickly. FrontiersPhysical therapy and gentle activity.
Fatigue, big bellies, and anemia can reduce activity. Purpose: maintain strength and mobility. Mechanism: graded activity improves muscle function, appetite, and mood without over-straining the heart or kidneys. NCBIMonitoring for portal-hypertension complications.
Liver fibrosis can lead to varices and spleen enlargement. Purpose: prevent bleeding. Mechanism: scheduled specialist visits and endoscopic screening allow early banding of varices if needed. MedscapeEndoscopic variceal band ligation (procedure).
If large esophageal varices are present, a gastroenterologist can tie them off. Purpose: prevent or stop GI bleeding. Mechanism: rubber bands strangulate the varix so it scars shut, lowering bleeding risk. FrontiersAnemia management plan (non-drug parts).
Anemia is common in CKD. Purpose: improve energy and growth. Mechanism: dietitian-guided iron intake, minimizing frequent blood draws, and treating infections reduce non-drug causes of anemia; medications are added if needed (see drug section). NCBIDental and oral-health care.
Bleeding risk (varices), anemia, and future transplant plans make oral health important. Purpose: lower bacteremia/heart and liver risks. Mechanism: proactive cleanings and cavity control reduce systemic infection load. NCBIGentle fluid-management guidance.
Some ARPKD patients need careful hydration; others need limits if swelling or heart strain occurs. Purpose: avoid dehydration (worsens kidneys) and fluid overload (worsens lungs/BP). Mechanism: day-to-day targets adapted to labs, BP, and swelling. NCBISchool and psychosocial support.
Chronic disease affects learning and family stress. Purpose: keep life as normal as possible. Mechanism: Individualized Education Plans, support groups, and counseling lower anxiety and improve adherence and outcomes. pkdcure.orgGenetic counseling for the family.
Parents are usually healthy carriers; each pregnancy has a 25% chance of ARPKD. Purpose: give clear family-planning facts. Mechanism: pedigree review, carrier testing, and discussion of prenatal imaging/testing aid informed decisions. NCBIPrenatal monitoring (for future pregnancies).
Ultrasound may show enlarged echogenic kidneys and low amniotic fluid. Purpose: plan delivery and newborn care. Mechanism: serial imaging and maternal-fetal care prepare teams for respiratory and renal support at birth. NCBICKD-mineral bone disorder counseling.
Abnormal calcium/phosphate balance harms bones. Purpose: protect bones and growth plates. Mechanism: diet changes and timing of binders/vitamin D (if prescribed) plus lab checks keep minerals in range. NCBIPeritoneal dialysis (PD) education before it is needed.
Many children with ARPKD eventually need renal replacement therapy. Purpose: smooth, prepared transition. Mechanism: early teaching on PD catheter care, nightly cycler use, and infection signs reduces complications when dialysis starts. NCBIHemodialysis (HD) pathway planning.
Some centers choose HD instead of PD. Purpose: ensure safe access and schedules. Mechanism: timely vascular access planning and dry-weight setting avoid fluid overload and support growth while waiting for transplant. NCBITransplant evaluation (kidney or combined liver-kidney).
Transplant is often the best long-term option when kidneys fail; some children need both organs due to severe liver disease. Purpose: restore kidney function and control portal-hypertension complications when medical/endoscopic care is not enough. Mechanism: surgery replaces the failing organ(s) and removes the cystic kidney bulk if needed. NCBI+1

Immunity-booster / regenerative / stem-cell drugs
There are no FDA-approved “immunity-booster,” regenerative, or stem-cell drugs for ARPKD. Using such products outside a clinical trial can be unsafe and misleading. What we do have are evidence-based ways to lower infection risk and protect organs:
Vaccines (routine schedule; product labels per vaccine) – reduce severe infections in children with chronic disease.
RSV monoclonal antibodies (nirsevimab or palivizumab) in eligible infants – passive immunity for the RSV season. FDA Access Data+1
Nutrition correction (iron, vitamin D, zinc if deficient) – supports normal immune function; not “boosters.” NCBI
Prompt, guideline-based antibiotics for cholangitis/UTI – treats infection fast to prevent sepsis. Frontiers
Anemia treatment with ESAs when indicated – improves oxygen delivery and resilience. FDA Access Data
Transplantation (kidney ± liver) when criteria are met – restores organ function; this is the proven “regenerative” step available today. NCBI
Surgeries / procedures
Peritoneal dialysis catheter placement.
A soft tube is placed in the belly for home dialysis when kidneys can’t keep up. Why: gentle fluid removal and toxin control in infants/children. NCBIHemodialysis vascular access (catheter/fistula).
Creates a reliable access to filter blood outside the body. Why: provides life-saving dialysis when PD is not suitable. NCBIEndoscopic variceal band ligation.
A scope places tiny rubber bands on swollen veins in the esophagus. Why: prevent or stop dangerous GI bleeding due to portal hypertension. FrontiersKidney transplant.
A healthy kidney from a donor is placed to replace kidney function. Why: best long-term option after kidney failure; improves growth and quality of life. NCBICombined liver–kidney transplant (selected cases).
Both organs are transplanted when liver disease with portal-hypertension complications cannot be controlled and kidney failure is present. Why: treats both organ problems at once. Frontiers
Prevention tips
You cannot prevent the gene change, but you can reduce complications with early diagnosis and regular specialist care. NCBI
Keep blood pressure in target with home checks, low-salt eating, and medicines as prescribed. NCBI
Follow a renal diet plan to protect growth and reduce swelling and mineral problems. NCBI
Vaccinate on time and ask about RSV prophylaxis if eligible. FDA Access Data
Have a fever plan: know when to get urine/blood tests quickly. Frontiers
Avoid NSAIDs unless a clinician says they’re safe for your child; use safer pain options. NCBI
Keep all nephrology and hepatology appointments, including ultrasound/endoscopy schedules. NCBI
Protect teeth and gums to reduce infection risk before any transplant. NCBI
Plan ahead for dialysis or transplant so access and evaluations aren’t rushed. NCBI
Use genetic counseling for family planning. NCBI
When to see a doctor urgently
New or worsening breathing trouble, severe tummy swelling, or very high blood pressure readings.
Fever, chills, right-upper-belly pain, or jaundice, which can signal cholangitis.
Bloody vomit or black stools, which can signal variceal bleeding.
Very little urine, swelling of legs/face, severe headaches, or seizures with sky-high BP.
These signs need same-day medical care. Frontiers+1
What to eat
Eat more of:
Fresh fruits and vegetables suited to the child’s potassium limits (dietitian will guide).
High-calorie, nutrient-dense foods (nut butters, fortified formulas) to support growth.
Adequate protein for age/CKD stage (nephrology dietitian sets targets).
Whole-grain carbs for steady energy when phosphorus/potassium allowances permit.
Healthy fats (olive oil, canola; omega-3s if approved).
Avoid/limit:
- High-salt foods (packaged snacks, instant noodles, fast food).
- Excess potassium foods (bananas, potatoes, certain juices) if labs run high.
- Excess phosphorus (dark colas, processed cheeses) if phosphorus is high.
- Herbal “kidney cleanses”—often unsafe in CKD.
- NSAIDs without approval (ibuprofen/naproxen), which can reduce kidney blood flow. NCBI
Frequently asked questions
Is ARPKD the same as ADPKD?
No. ADPKD is usually adult-onset and dominant; ARPKD is recessive and often shows up in babies/children with liver fibrosis. NCBIWill every child with ARPKD need dialysis or transplant?
Many do over time, but the age and speed vary widely. Close blood-pressure control and infection prevention help. NCBICan medicines stop cysts from growing in ARPKD?
There is no approved cyst-stopping drug for ARPKD today; care targets complications. (Tolvaptan is an adult ADPKD drug, not approved for ARPKD.) UpToDateWhy is blood pressure such a big deal?
High BP accelerates kidney damage and harms the heart and eyes; controlling it slows decline. NCBIWhy is the liver involved?
ARPKD includes congenital hepatic fibrosis, which raises portal vein pressure and can cause varices and infections. PMC+1How are bile-duct infections treated?
With urgent IV antibiotics and sometimes drainage or endoscopy; delays are dangerous. FrontiersWhat is the role of ursodiol?
It can help bile flow in some cholestatic diseases, but it’s not ARPKD-specific and is used off-label based on the child’s situation. FDA Access DataCan my child play sports?
Often yes, with adjustments and blood-pressure control. Avoid contact sports if the spleen is very enlarged (bleeding risk). NCBIWill my other children have ARPKD?
Each pregnancy has a 25% chance if both parents are carriers; healthy siblings can be carriers. Genetic counseling helps. NCBIIs a combined liver–kidney transplant common?
It’s done in selected children with severe liver disease plus kidney failure when other measures aren’t enough. FrontiersDo we need a special dentist?
A dentist comfortable with children who have chronic conditions is ideal; oral infections can be serious. NCBIWhy avoid NSAIDs?
They can reduce kidney blood flow and worsen function, especially in CKD. Use alternatives approved by the care team. NCBICan ARPKD be seen on prenatal ultrasound?
Often yes—enlarged, echogenic kidneys and low amniotic fluid can be clues. NCBIWill growth be normal?
Growth can be challenging but improves with good nutrition, BP control, anemia treatment, and transplant when needed. NCBIWhere can we read reliable summaries?
GeneReviews (clinician-level), NORD, and national kidney-liver centers provide trusted information. NCBI+
