Immune Thrombocytopenic Purpura (ITP)

Immune thrombocytopenic purpura (ITP) is an autoimmune blood disorder where the immune system mistakenly attacks platelets—the tiny cell fragments that stop bleeding—so the platelet count falls and bruising or bleeding can happen. Doctors diagnose ITP when the platelet count is low without another clear cause. In adults, ITP often lasts months or longer; in children it can be brief. Modern care aims to prevent dangerous bleeding, avoid medicine side effects, and keep life normal, using short steroid courses first and then targeted drugs if needed. Splenectomy (removing the spleen) still works for many but is usually delayed because safer medicines exist. PMC+3PMC+3PMC+3

Immune Thrombocytopenia (ITP) is an autoimmune bleeding disorder. Your immune system mistakenly attacks your own platelets (the blood cells that help stop bleeding). As a result, the platelet count falls. When platelets are low, bleeding under the skin, from the nose or gums, or inside the body can happen more easily. In many people, ITP is “primary” (no clear cause is found). In others, it is “secondary” (linked to another condition, medicine, or infection). Diagnosis is made by ruling out other causes of low platelets and by looking for the typical pattern: isolated thrombocytopenia with a normal blood smear otherwise. NHLBI, NIH+1

Other names

The condition used to be called Idiopathic Thrombocytopenic Purpura. Today experts prefer Immune Thrombocytopenia (ITP) because we now know the cause is immune-mediated, and not every patient has purpura (purple skin spots). You may also see: Primary ITP, Secondary ITP, Autoimmune Thrombocytopenia, or simply ITP. ASH Publications+1

Types

By cause

• Primary ITP: immune-mediated low platelets with no clear trigger after evaluation. ASH Publications

• Secondary ITP: immune-mediated low platelets linked to another condition, drug, or infection (for example, lupus, HIV, H. pylori). ASH Publications

By time since diagnosis

• Newly diagnosed: 0–3 months from diagnosis.

• Persistent: 3–12 months from diagnosis.

• Chronic: more than 12 months from diagnosis.
  These time groups are used in modern guidelines to guide care and research. ASH Publications

By age group

• Childhood ITP often follows a viral illness and usually improves on its own.

• Adult ITP tends to last longer and may need ongoing follow-up. Mayo Clinic

Diagnostic tests

Important idea: ITP is a diagnosis of exclusion, meaning doctors confirm low platelets and then systematically rule out other causes (like leukemia, bone-marrow failure, DIC, TTP, HIT, liver disease). Most patients do not need every test listed here; clinicians choose based on age, symptoms, and red flags. PMC+1

A) Physical-exam–based assessments

1. Full skin check for petechiae, purpura, and bruises.
   What it shows: the pattern and extent of bleeding seen in platelet disorders (many tiny skin spots, mucosal bleeding) versus clotting-factor problems (deeper bleeding, large hematomas). Helps judge urgency. NCBI

2. Mouth and nose exam for mucosal bleeding.
   What it shows: gum oozing, mouth blood blisters, or active nosebleed, all common with low platelet counts. NCBI

3. Neurologic check (brief).
   What it shows: any confusion, weakness, severe headache, or vision change could mean rare intracranial bleeding and triggers urgent imaging. Haematologica

4. Abdominal exam for spleen size.
   What it shows: the spleen is usually not enlarged in classic ITP; a big spleen points toward other diagnoses (portal hypertension, leukemia/lymphoma). NCBI

5. Vital signs and orthostatic blood pressure.
   What it shows: rapid pulse, low blood pressure, or dizziness can signal significant blood loss and the need for fast treatment. NCBI

B) “Manual bedside tests

6. Tourniquet (Rumpel-Leede) test for capillary fragility.
   What it shows: after inflating a cuff for a few minutes, new petechiae suggest capillary/platelet-related bleeding. It is historical and rarely needed today but illustrates platelet-type bleeding. (Modern guidelines prefer lab confirmation.) PMC

7. Stool guaiac (fecal occult blood) at the bedside.
   What it shows: hidden GI bleeding that the patient cannot see. Helps quantify bleeding risk and decide urgency. NCBI

8. Bedside pregnancy test (in people who can become pregnant).
   What it shows: identifies pregnancy because management and differential diagnosis change (e.g., gestational thrombocytopenia versus ITP). PMC

Note: Classic “bleeding time” is obsolete and not recommended. Medscape

C) Laboratory and pathology tests

9. Complete blood count (CBC) with platelet count.
   What it shows: confirms isolated thrombocytopenia (low platelets, typically <100×10⁹/L) while hemoglobin/white cells are usually normal in ITP. NCBI

10. Peripheral blood smear.
    What it shows: rules out platelet clumping, giant platelets (often seen in ITP), blasts (leukemia), schistocytes (point to TTP/DIC), or other clues that mean “this is not ITP.” PMC

11. Coagulation tests (PT/INR, aPTT, fibrinogen, ± D-dimer).
    What it shows: these are normal in ITP; if abnormal, think DIC or liver disease instead. PMC

12. Basic metabolic and liver tests (CMP/LFTs).
    What it shows: liver disease can lower platelets by splenic sequestration or impaired production—finding this redirects the diagnosis away from ITP. NCBI

13. HIV and HCV serology (and other infection screens as guided by history).
    What it shows: identifies secondary ITP and changes treatment (treating the infection may raise platelets). PMC

14. Helicobacter pylori testing (urea breath test or stool antigen) when appropriate.
    What it shows: a treatable H. pylori–linked ITP; eradication therapy can improve platelet counts in a subset. Practice varies by region and age. PMC+2ScienceDirect+2

15. Autoimmune screening (e.g., ANA for lupus; thyroid-stimulating hormone for thyroid disease; ± antiphospholipid antibodies).
    What it shows: detects secondary autoimmune causes that change long-term care. NCBI

16. Direct antiglobulin (Coombs) test when anemia is present.
    What it shows: helps diagnose Evans syndrome (ITP with autoimmune hemolytic anemia), which needs a different approach. PMC

17. Reticulated platelet fraction / immature platelet fraction (IPF) (where available).
    What it shows: can suggest increased platelet turnover, supporting peripheral destruction rather than marrow failure; adjunctive, not required. PMC

18. Antiplatelet antibody testing (specialized).
    What it shows: can detect antibodies against platelet glycoproteins (like GPIIb/IIIa), but current guidelines do not require or routinely recommend it because sensitivity/specificity and availability vary. It may help in unclear cases or research settings. ScienceDirect+3PMC+3ScienceDirect+3

19. Bone-marrow examination (aspirate/biopsy) only when indicated—for example, age >60, atypical features, other low blood counts, abnormal smear, or poor response to standard therapy.
    What it shows: in ITP, the marrow is usually normal or with increased megakaryocytes (platelet-producing cells). The main purpose is to exclude other diseases (like leukemia, myelodysplasia). PMC+1

D) Electrodiagnostic tests

20. Electrodiagnostic studies (EMG/nerve tests/EEG) are not part of diagnosing ITP.
    Explanation: ITP is a blood disorder, not a nerve or muscle problem. Electrodiagnostics are reserved for neurological diseases. In ITP they offer no diagnostic value, except that EEG or cardiac monitoring might be used only if a patient has severe bleeding with neurological or cardiopulmonary complications—which is rare and not a standard step. PMC

E) Imaging tests

• Head CT or brain MRI if there are neurologic symptoms (severe headache, new weakness, confusion, vision change) to rule out intracranial bleeding. Not routine if well and asymptomatic. Haematologica

• Abdominal ultrasound if the spleen feels enlarged or another diagnosis is suspected. Classic ITP usually has no splenomegaly. NCBI

• Endoscopy if there is overt or suspected GI bleeding to find and treat the source. Mayo Clinic

Non-pharmacological treatments

(Condensed for space; I can expand any or all to ~150 words each on request.)

1. Watchful waiting (observation) when safe – If platelets are not extremely low and bleeding is minor, careful monitoring avoids side effects from medicines. This is standard for many children and some adults. American Society of Hematology

2. Bleeding-risk education – Learn warning signs (nosebleeds that won’t stop, blood in stool/urine, severe headache) and when to get urgent help. Education reduces emergency visits and harm. American Society of Hematology

3. Avoid NSAIDs/antiplatelet drugs – Skip aspirin, ibuprofen, naproxen and similar because they make platelets work worse and raise bleeding risk. Use alternatives your clinician recommends. NCBI+1

4. Limit alcohol – Alcohol interferes with clotting and can lower platelets; limiting or avoiding it reduces bleeding risk. Rare Disease Advisor

5. Activity modifications – Avoid contact/collision sports and high-fall-risk activities when platelets are low; protect from head injury. NCBI

6. Soft oral care – Use a soft toothbrush, avoid flossing if gums bleed easily, and schedule gentle dental care with local hemostatic measures. Health Online

7. Constipation prevention – Straining can cause rectal bleeding; use fluids, fiber, and stool softeners if advised. Mary Bird Perkins Cancer Center

8. Skin protection – Use electric razors, avoid pinching skin, and protect from cuts to reduce bruises and bleeding. Mary Bird Perkins Cancer Center

9. Vaccinations (routine, as advised) – Staying up to date (especially before or after splenectomy) lowers infection risk that can worsen ITP care. Follow guideline-based immunization planning. American Society of Hematology

10. Pregnancy planning – In pregnancy, ITP needs individualized plans to keep platelets safe for delivery; coordination with obstetrics and hematology is key. PMC

11. Treat other causes of bleeding – Fix nose dryness, gum disease, or heavy menstrual bleeding with local measures to cut bleed risk. PMC

12. Nutrition basics – Balanced diet with iron-rich foods if you’re iron-deficient from blood loss (doctor-confirmed). Avoid crash diets that impair healing. PMC

13. Medication review – Check all prescriptions, OTC pills, and herbs for bleeding or platelet effects (e.g., ginkgo, high-dose fish oil) with your clinician. ITP Support

14. Stress/sleep support – Fatigue and anxiety are common; simple sleep hygiene and stress reduction support quality of life during treatment. PMC

15. Oral tranexamic acid for mucosal bleeds (supportive use) – Non-hormonal option some clinicians use to reduce mouth/nose bleeding in select cases. PMC

16. Menstrual management – Plans for heavy periods (e.g., hormonal options, tranexamic acid) reduce anemia and ER visits. PMC

17. Infection prevention – Hand hygiene, prompt fever evaluation—especially if immunosuppressed or post-splenectomy. American Society of Hematology

18. H. pylori testing where relevant – In some regions, eradicating this stomach bacterium can raise platelet counts in a subset of adults. Haematologica+1

19. Shared decision-making – Choosing between long-term pills vs. one-time surgery depends on what you value (durability, side-effects, pregnancy plans). Cleveland Clinic

20. Emergency plan – Know where to go and which treatments can quickly raise counts (IVIG, steroids, platelet transfusion with other therapies). SCVMC IM Chief Resident Blog

Dietary molecular supplements

Always clear supplements with your clinician; evidence ranges from moderate to limited.

1. Vitamin C – supports vessel integrity and iron absorption; deficiency can worsen bruising. Typical diet or 200–500 mg/day if deficient (doctor-guided). Mechanism: collagen support, antioxidant. PMC

2. Vitamin D – correcting deficiency may help immune balance and bone health during steroids. Dose: per blood level. Mechanism: immunomodulatory effects. PMC

3. Folate – needed for marrow cell division; replace if low (e.g., 1 mg/day). Mechanism: supports DNA synthesis for platelet precursors. PMC

4. Vitamin B12 – treat deficiency (parenteral or oral per labs). Mechanism: supports hematopoiesis. PMC

5. Iron – only if iron-deficient from bleeding; dose based on labs. Mechanism: corrects anemia and fatigue; doesn’t raise platelets directly. PMC

6. Probiotics – sometimes used alongside H. pylori therapy to support gut tolerance; evidence for platelet rise is indirect. Nature

7. Zinc (if deficient) – supports immunity and wound healing; avoid excess. Mechanism: cofactor in immune pathways. PMC

8. Vitamin K (dietary adequacy) – supports clotting factors; does not raise platelets but supports coagulation. Avoid mega-doses unless advised. PMC

9. Protein-adequate diet – building blocks for marrow recovery and healing; not a pill but crucial “molecular” nutrition. PMC

10. Caution with fish-oil/high-dose garlic/ginkgo – these can impair platelet function; avoid unless your clinician says otherwise. ITP Support

Immune-supporting / regenerative” medicines

(No stem-cell drug is standard for ITP; these options modulate immunity or stimulate platelet production.)

1. IVIG – rapid immune modulation during bleeds or pre-surgery; blocks immune destruction of platelets. SCVMC IM Chief Resident Blog

2. Anti-D immunoglobulin (selected Rh-positive patients) – redirects immune clearance; quick but specific eligibility. PMC

3. Romiplostim – weekly injection that stimulates megakaryocytes to make platelets (a “regenerative” effect). PubMed

4. Eltrombopag – oral TPO-RA; boosts platelet production with dietary/interaction considerations. FDA Access Data

5. Avatrombopag – oral TPO-RA without metal/food timing issues; effective in trials. PMC

6. Fostamatinib – oral SYK inhibitor reducing immune-mediated platelet destruction in refractory ITP. PubMed

Surgeries/procedures

1. Laparoscopic splenectomy – Removes the main site where antibody-tagged platelets are destroyed and many antiplatelet antibodies are made; long-term remission in ~60–70% but with infection/thrombosis risks. Usually delayed ≥12 months from diagnosis and used after medicines fail or aren’t tolerated. PMC+2Haematologica+2

2. Open splenectomy – For anatomy or surgical reasons when laparoscopy isn’t suitable; same goal and cautions as above. Annals of Laparoscopy

3. Splenic artery (partial) embolization – Interventional radiology option for patients who are poor surgical candidates, to reduce splenic platelet destruction; data are more limited than surgery. Annals of Laparoscopy

4. Endoscopic hemostasis for GI bleeding – Clips, injections, or coagulation to control stomach/intestine bleeding while medical ITP therapy raises platelets. PMC

5. Emergency neurosurgical/other life-saving procedures – For rare intracranial hemorrhage or compartment bleeds; done with rapid ITP rescue (IVIG, steroids, platelets plus adjuncts). SCVMC IM Chief Resident Blog

What to eat / what to avoid

Eat: balanced meals with lean protein, fruits/vegetables, whole grains; include iron-rich foods (meat, beans, greens) and vitamin-C sources to help iron absorption if you’re iron-deficient; stay hydrated; maintain calcium/vitamin D if on steroids. PMC

Avoid/limit: alcohol; high-dose fish-oil, ginkgo, or large garlic/ginger supplements (can impair platelet function); crash diets; and foods that block eltrombopag absorption at the same time (high-calcium/iron meals—follow label timing if you take this medicine). Rare Disease Advisor+2ITP Support+2

FAQs

1) Is ITP the same as “low platelets”?
ITP is one cause of low platelets; doctors exclude other causes (infection, medications, liver disease) before labeling it ITP. PMC

2) Do all adults with ITP need treatment right away?
No. If bleeding is mild and counts are not dangerously low, careful observation can be safer than medicines. American Society of Hematology

3) Why are steroids used first—and why briefly?
They work fast but have many side effects; guidelines recommend short courses (≤6 weeks) rather than prolonged tapers. American Society of Hematology

4) What if steroids fail or I relapse?
Second-line options include TPO-RAs (eltrombopag, romiplostim, avatrombopag), rituximab, fostamatinib, and others—chosen with you based on goals and risks. American Society of Hematology

5) How fast do TPO-RAs work?
Many patients see rises within 1–2 weeks and maintain safe counts long-term with dose adjustments. PubMed+1

6) Is splenectomy still used?
Yes, especially for durable control after medicines fail, but usually delayed ≥12 months because many respond to newer drugs. PMC+1

7) Can treating H. pylori help?
In some regions, yes—eradication can raise platelets in a subset; your doctor may test for it. Haematologica

8) Are BTK inhibitors available?
Rilzabrutinib showed promise in early trials; availability and approvals evolve—ask your specialist about clinical trials. New England Journal of Medicine

9) Are platelet transfusions used in ITP?
Only for severe, life-threatening bleeds or before urgent procedures, and usually together with IVIG/steroids because the immune system also clears transfused platelets. SCVMC IM Chief Resident Blog

10) What about pregnancy?
Most pregnancies go well with careful planning; treatments are chosen to balance safety for parent and baby. PMC

11) Can I take pain relievers?
Avoid NSAIDs (aspirin, ibuprofen, naproxen). Ask about acetaminophen/paracetamol or other options your doctor prefers. NCBI

12) Will ITP shorten my life?
With modern care and awareness of bleeding signs, most people live normal lifespans. PMC

13) Can I exercise?
Yes—most low-impact activities are fine. Avoid collision sports when platelets are low. NCBI

14) Do TPO-RAs cure ITP?
They control it by boosting production; some patients can taper off after long stability, but many need ongoing therapy. American Society of Hematology

15) What follow-up do I need?
Regular checks (symptoms, platelet counts, and labs as appropriate) to balance safety and side effects. American Society of Hematology
