Alpha-2-Plasmin Inhibitor (α2-Antiplasmin) Deficiency

Alpha-2-plasmin inhibitor deficiency (also written as α2-antiplasmin deficiency) is a rare bleeding disorder. In healthy blood, clots form to stop bleeding and then slowly dissolve when healing is complete. A protein called α2-antiplasmin (made from the SERPINF2 gene) is the body’s main “brake” on plasmin, the enzyme that dissolves clots (fibrinolysis). If α2-antiplasmin is missing or weak, plasmin is too active. Clots dissolve too fast. Bleeding may start again after it first seems to stop, especially after injury or surgery. This is why people with this deficiency often have delayed or prolonged bleeding even when routine clotting tests are normal. The condition can be inherited (congenital, usually autosomal recessive) or acquired later in life. PMC+2NCBI+2

Alpha-2-plasmin inhibitor (often called α2-antiplasmin or A2AP) is a natural protein in your blood. Its job is to protect a fresh clot so it can stop bleeding. It does this by blocking plasmin, the enzyme that cuts fibrin and dissolves clots. If your body has too little A2AP, or it does not work well, clots break down too fast. That means you can bleed more and bleed longer, especially after injuries, dental work, surgery, or childbirth. Doctors call this problem alpha-2-plasmin inhibitor deficiency. It is rare. The inherited (congenital) form is usually autosomal recessive and is caused by changes in a gene named SERPINF2. Heterozygous people (one changed copy) may have mild or no symptoms; people with two changed copies can have more bleeding, sometimes starting in childhood (for example, prolonged umbilical stump bleeding). Wikipedia+2NCBI+2

Another names

Doctors and labs may use several names that mean the same thing:

• Alpha-2-antiplasmin deficiency

• Alpha-2-plasmin inhibitor deficiency

• Plasmin inhibitor deficiency

• SERPINF2 deficiency

• A2AP deficiency

These terms all point to the same problem—too little working α2-antiplasmin and too much fibrinolysis. Wikipedia+1

When a clot forms, factor XIII “locks” the clot together and cross-links α2-antiplasmin onto the fibrin mesh, so the clot resists early breakdown. If α2-antiplasmin is absent, defective, or not properly cross-linked, plasmin can chew through the clot too quickly. This shows up as re-bleeding after an apparently stable clot (“delayed bleeding”). In severe, complete congenital deficiency, bleeding can resemble hemophilia; people with one working gene copy may have mild or no symptoms. PMC+1

Types

1. By cause

• Congenital (inherited): due to disease-causing variants in the SERPINF2 gene; most often autosomal recessive. NCBI+1

• Acquired: α2-antiplasmin becomes low or is consumed/loses function because of another condition or medication (examples below in “Causes”). rarecoagulationdisorders.org

2. By what’s wrong with the protein

• Quantitative deficiency (Type I): not enough α2-antiplasmin is made (low activity and low antigen).

• Qualitative deficiency (Type II): a normal amount is present, but it doesn’t work well (activity low, antigen normal), sometimes because it cannot be cross-linked well to fibrin. ASH Publications

3. By severity

• Complete/severe deficiency: very low activity, often with early-life or postsurgical bleeding.

• Partial/heterozygous deficiency: activity about half-normal; many people are asymptomatic or bleed only with significant challenges (major dental work, surgery, childbirth). ASH Publications

Causes

Congenital (genetic) causes

1. Pathogenic variants in SERPINF2 lead to little or no functional α2-antiplasmin (autosomal recessive). NCBI

2. Missense variants producing a dysfunctional protein (qualitative defect). PreventionGenetics

3. Frameshift/nonsense variants that truncate the protein (quantitative defect). PreventionGenetics

4. Variants affecting the cross-linking site (cannot attach to fibrin efficiently), creating a functional loss at the clot surface. ScienceDirect

Diagnostic tests

A) Physical-exam–based assessments (what a clinician looks for)

1. Skin and soft-tissue check for large bruises or deep, tender swellings that suggest muscle/soft-tissue bleeds; in α2-antiplasmin deficiency, bruising can be prominent after small bumps. rarecoagulationdisorders.org

2. Joint exam for warmth, swelling, or limited movement after injury, suggesting a post-traumatic joint bleed (less often spontaneous than in hemophilia). rarecoagulationdisorders.org

3. Mouth and nose inspection for mucosal oozing (gums, nose), a common site for fibrinolytic bleeding. rarecoagulationdisorders.org

4. Surgical-site and wound checks for delayed oozing hours after closure, a classic clue in hyperfibrinolysis. PMC

5. General bleeding history captured systematically (for example with the ISTH Bleeding Assessment Tool) to quantify how “bleedy” daily life has been and decide on lab testing. JTH Journal+1

B) “Manual” or bedside assessments (simple, low-tech checks)

6. Careful post-venipuncture observation (does a small needle site ooze longer than expected?), which can hint at fibrinolytic bleeding and prompt targeted tests. PMC

7. Compression/gauze pressure test on a minor cut—persistent oozing after firm pressure is another practical clue (supportive, not diagnostic on its own). PMC

8. Structured bleeding questionnaire (ISTH-BAT or self-BAT) completed in clinic; high scores support a true bleeding tendency and justify specialized testing. PubMed+1

9. Medication review “challenge”—documenting whether NSAIDs or other drugs worsen bleeding, since mucosal oozing often increases with these agents. rarecoagulationdisorders.org

10. Family mapping/pedigree when congenital disease is suspected (autosomal recessive patterns; consanguinity may be a clue). National Organization for Rare Disorders

Note: These bedside checks do not prove the diagnosis. They signal when to order the specialized labs below.

C) Laboratory and pathological tests (the core of diagnosis)

11. Routine coagulation tests—PT/INR, aPTT, platelet count are often normal, which helps shift attention to fibrinolysis rather than clotting factor or platelet disorders. PubMed

12. α2-antiplasmin activity assay (functional)—the key test; low activity confirms deficiency (severity helps predict symptoms). Some centers also measure antigen (protein amount) to tell quantitative from qualitative defects. rarecoagulationdisorders.org

13. Euglobulin clot lysis time (ECLT/ELT)—a global fibrinolysis test often shortened when inhibitors like α2-antiplasmin are low. Many labs now replace it with newer assays. practical-haemostasis.com

14. Global fibrinolysis capacity (GFC)—an instrumented assay that quantifies how fast plasma lyses a standardized clot; useful where available. PMC

15. D-dimer and fibrin degradation products (FDPs)—may be elevated because clots break down excessively; supportive rather than specific. ARUP Consult

16. Plasmin–antiplasmin complex levels—can be high when plasmin activity is excessive; supports a fibrinolytic disorder. PubMed

17. Plasmin generation assays—research/advanced tests showing increased plasmin generation in severe deficiency. ScienceDirect

18. Factor XIII activity and cross-linking studies (including classic 5M urea clot-solubility test): mainly to exclude FXIII deficiency, which also causes unstable clots; lack of α2-antiplasmin cross-linking can exaggerate lysis. PMC+1

19. Genetic testing of SERPINF2—confirms congenital cases, helps family counseling. PreventionGenetics

20. Rule-out tests for “look-alikes” in the fibrinolysis pathway: PAI-1 deficiency (excess tPA activity), plasminogen disorders, VWD/platelet function if symptoms suggest mixed mechanisms. These help place α2-antiplasmin deficiency in context. ARUP Consult

D) Electrodiagnostic / device-based hemostasis tests (showing hyperfibrinolysis in real time)

21. Thromboelastography (TEG)—a viscoelastic test on whole blood. The LY30 value (percent clot lysis 30 minutes after peak strength) rises with hyperfibrinolysis; values ≥3% are commonly considered clinically significant in trauma literature. PMC+1

22. Rotational thromboelastometry (ROTEM)—similar concept; maximum lysis (ML) and APTEM/EXTEM comparisons help confirm pathologic fibrinolysis. TTUHSC

E) Imaging tests (to locate and size bleeds)

23. Ultrasound—helps find soft-tissue hematomas and joint effusions after injury. Useful at bedside, no radiation. rarecoagulationdisorders.org

24. MRI—best detail for muscle bleeds, deep soft-tissue collections, and joint damage from repeated hemarthrosis. rarecoagulationdisorders.org

25. CT of head/chest/abdomen/pelvis—used when internal bleeding is suspected (for example, after major trauma or surgery). PMC

26. Endoscopy—if there are signs of gastrointestinal bleeding, endoscopy helps find the source and treat it. PMC

Drug treatments

Important safety note: doses below are typical references and must be individualized by your clinician, especially in kidney disease, pregnancy, children, or if you take other medicines that affect clotting.

1. Tranexamic acid (TXA) — Antifibrinolytic
   Dose & time: Dental/surgical protocols in congenital A2AP deficiency often use 7.5–10 mg/kg orally every 6 hours, starting 3 hours before procedure and continuing ~7 days; other bleeding indications commonly use 1–1.5 g orally 3–4 times daily for 3–4 days, per general TXA guidance. Purpose: prevent and treat mucosal/surgical bleeding. Mechanism: blocks plasminogen activation and plasmin binding to fibrin. Side effects: nausea, rare visual changes, very rare thrombosis; adjust in renal impairment. PubMed+1

2. Epsilon-aminocaproic acid (EACA; aminocaproic acid) — Antifibrinolytic
   Dose & time: 50–100 mg/kg per dose every 6 hours (max 30 g/day) used in bleeding disorders with hyperfibrinolysis. Purpose: alternative to TXA, useful for oral/nasal/urinary tract bleeding. Mechanism: lysine analog that blocks plasmin activity. Side effects: nausea, muscle cramps; caution in kidney disease. rarecoagulationdisorders.org

3. Fresh frozen plasma (FFP) — Blood product replacement of A2AP
   Dose & time: Peri-operative or for major bleeds; dosing individualized (e.g., 10–15 mL/kg) in consultation with hematology. Purpose: supplies exogenous α2-antiplasmin (and other inhibitors) when your level is very low. Mechanism: direct replacement; stabilizes clots. Side effects: transfusion reactions, TRALI, volume overload. Herald Open Access

4. Topical TXA (mouthwash/soaked swab) — Local antifibrinolytic
   Dose & time: As prescribed (common: 5% solution held in mouth several minutes, repeated per plan). Purpose: control oral bleeds. Mechanism: local plasmin blockade. Side effects: minimal, avoid swallowing large amounts. PubMed

5. Fibrin sealant (fibrin glue) — Topical hemostat
   Dose & time: Applied by surgeon to the wound. Purpose: adds fibrin to strengthen clots in dental, ENT, surgical fields. Mechanism: mimics last step of coagulation; resists lysis when combined with TXA. Side effects: rare allergy.

6. Hormonal therapies for heavy menstrual bleeding (e.g., levonorgestrel IUD, combined oral contraceptives)
   Dose & time: Standard gynecology regimens. Purpose: reduce menstrual blood loss. Mechanism: thins endometrium, reduces bleeding surface. Side effects: vary by agent (nausea, spotting, breast tenderness).

7. Tranexamic acid for menses
   Dose & time: Common non-specific menorrhagia regimen: 1–1.3 g orally three times daily for up to 5 days during menses (per heavy menstrual bleeding data). Purpose: reduce menstrual blood loss. Mechanism: antifibrinolysis of endometrium. Side effects: as above. PMC

8. Desmopressin (DDAVP) — Selective use
   Note: Not a core therapy for A2AP deficiency because it raises vWF/FVIII, not A2AP, but may help some mucosal bleeds when combined with antifibrinolytics in selected cases. Side effects: hyponatremia; use with caution.

9. Recombinant factor VIIa (rFVIIa) — Rescue measure
   Use: Rare, off-label for uncontrolled life-threatening bleeding when standard measures fail, under specialist guidance. Risk: thrombosis.

10. Antifibrinolytic infusion protocols (peri-operative TXA IV)
    Dose & time: Common surgical regimens use 15 mg/kg IV bolus before incision, then 5 mg/kg/h infusion until end of surgery (general TXA data). Purpose: cover high-risk procedures. Mechanism: continuous antifibrinolysis. Side effects: as TXA. BioMed Central

11. Aprotinin (topical or restricted systemic use)
    Use: Potent serine-protease inhibitor; systemic use is tightly restricted; topical use in the OR may be considered. Mechanism: inhibits plasmin. Risks: kidney issues, thrombosis; specialist decision only.

12. Antifibrinolytic-soaked nasal packs
    Dose: TXA solution as per ENT protocol. Purpose/mechanism: local plasmin block in epistaxis.

13. Uterotonic agents post-partum (e.g., oxytocin) in obstetric plans
    Purpose: reduce uterine bleeding from atony; combined with TXA as per obstetric guidelines.

14. Iron therapy (oral or IV, if anemic)
    Purpose: correct anemia due to recurrent bleeding; improves energy and healing.

15. Vitamin C (adjunct)
    Purpose: supports collagen and wound healing; not a substitute for antifibrinolytics.

16. Antifibrinolytic prophylaxis around dental/ENT procedures
    Purpose: prevent delayed bleeding; regimen individualized. PubMed

17. Peri-operative FFP + TXA bundle (case-based)
    Use: Selected major surgeries in severe deficiency may use FFP plus IV TXA per hematology plan. Herald Open Access

18. Antifibrinolytic therapy for bone/muscle bleeds
    Purpose: shorten bleeding and pain; plus immobilization.

19. Avoidance of fibrinolytic drugs (tPA)
    Purpose: prevent catastrophic bleeding in known deficiency. Mechanism: remove trigger of hyperfibrinolysis. rarecoagulationdisorders.org

20. Treat the cause in acquired deficiency
    Examples: manage liver disease, control DIC, treat nephrotic syndrome. Purpose: restore A2AP balance. rarecoagulationdisorders.org

Why so much focus on TXA/EACA? Because antifibrinolytic therapy is the cornerstone in A2AP deficiency—it directly counters the mechanism of bleeding (excess plasmin activity). PubMed

Dietary “molecular” supplements

These do not replace antifibrinolytic therapy. Discuss all supplements with your clinician.

1. Elemental iron (if iron-deficient): typical adult oral 40–65 mg elemental iron 1–2×/day; function: rebuild hemoglobin; mechanism: supplies iron for red cells.

2. Vitamin C 100–500 mg/day: function: collagen synthesis; mechanism: co-factor for wound healing.

3. Folate 400–800 mcg/day (diet or supplement if low): function: red cell production.

4. Vitamin B12 (if deficient): function: red cell maturation.

5. Vitamin D (per lab): function: immune and musculoskeletal health; indirect benefits.

6. Protein-rich nutrition (lean meats, legumes, dairy): function: provides amino acids for healing.

7. Zinc (short course if deficient): function: epithelial repair.

8. Copper (dietary sufficiency): function: connective tissue enzymes.

9. Omega-3 in food, not high-dose pills: moderate intake via fish; avoid high-dose capsules which may increase bleeding tendency.

10. Hydration & fiber: supports recovery and avoids straining after procedures.

Regenerative / stem-cell drugs

There are no approved immune-booster, regenerative, or stem-cell drugs that treat alpha-2-plasmin inhibitor deficiency. Using such products for this condition would be unsupported and potentially unsafe, so I can’t recommend them. The evidence-based approach is antifibrinolytics (TXA/EACA), FFP for severe cases or procedures, and careful local hemostasis. If you ever see a clinic or website claiming stem-cell or “immunity” cures for A2AP deficiency, please discuss it with a hematologist first. PubMed+1

Procedures/surgeries

1. Dental extraction with antifibrinolytic plan: Removal of a tooth using local hemostasis plus TXA before/after. Why: necessary dental care with safe bleeding control. PubMed

2. Nasal cautery/packing for recurrent epistaxis: Seals fragile vessels; often paired with topical TXA. Why: stop repeated nosebleeds.

3. Surgical evacuation of intramedullary hematoma (long bone): Orthopedic procedure; sometimes combined with TXA and fibrin glue at the site. Why: relieve pain and pressure, prevent damage. rarecoagulationdisorders.org

4. Gynecologic procedures for refractory heavy menses (e.g., endometrial ablation or, rarely, hysterectomy): Why: control bleeding when medical measures fail.

5. Interventional radiology embolization for a focal arterial source: Why: shut down a persistent bleeding vessel when other methods fail.

For any procedure, a peri-operative plan (antifibrinolytic + possible FFP) is essential in moderate–severe deficiency. Herald Open Access

Prevention tips

1. Carry a bleeding-disorder ID and a treatment card.

2. Tell every dentist/doctor before any procedure; ask for an A2AP-aware bleed plan.

3. Avoid intramuscular injections when alternatives exist.

4. Avoid high-dose NSAIDs (e.g., ibuprofen, naproxen) unless your doctor advises—can increase bleeding.

5. Do not take fish-oil, ginkgo, garlic, or high-dose vitamin E supplements without medical advice.

6. Use a soft toothbrush and gentle flossing; schedule dental cleanings with hemostasis in mind.

7. Manage nose dryness (saline gel/humidifier) to prevent nosebleeds.

8. Plan ahead for surgeries, childbirth, and dental work—loop in hematology early.

9. Treat underlying causes if acquired deficiency (liver, kidney, DIC). rarecoagulationdisorders.org

10. Keep iron-rich, balanced nutrition and stay hydrated.

When to see a doctor

• Bleeding that lasts longer than 20–30 minutes despite pressure.

• Delayed bleeding hours after dental work or surgery.

• Large bruises, deep muscle pain/swelling, or suspected bone pain after minor trauma.

• Heavy periods soaking through pad/tampon every hour for several hours, dizziness, or fatigue.

• Any head injury, black stools, coughing/vomiting blood, or blood in urine.

• Before any planned procedure, new prescription, or pregnancy planning.

What to eat and what to avoid

1. Eat: iron-rich foods (lean red meat, liver in moderation, beans, spinach, lentils).

2. Eat: vitamin-C foods with iron (citrus, guava, bell pepper) to absorb iron better.

3. Eat: protein with every meal (eggs, dairy, fish, legumes) to support healing.

4. Eat: whole grains, fruits, and vegetables for overall health.

5. Drink: plenty of water; dehydration can worsen headaches and fatigue.

6. Limit/avoid: alcohol excess—it can harm the liver (which makes A2AP).

7. Avoid: high-dose fish-oil, ginkgo, garlic, ginger, and vitamin E supplements unless your clinician approves.

8. Use caution: NSAIDs; ask your doctor for safer pain choices (e.g., acetaminophen if appropriate).

9. Avoid fad “blood-thinning” diets; they don’t treat this condition.

10. If anemic: add iron-rich foods and ask about iron supplements.

FAQs

1. Is α2-antiplasmin deficiency the same as hemophilia?
   No. Hemophilia is a problem making a clot; A2AP deficiency is a problem keeping the clot (it dissolves too fast).

2. What gene is involved?
   SERPINF2; inherited deficiency is usually autosomal recessive. Wikipedia

3. Can routine PT/aPTT tests find it?
   Often no—they may be normal. Special tests for fibrinolysis and A2AP activity/antigen are needed. PubMed+1

4. What is the first-line treatment for bleeds?
   Antifibrinolytics such as tranexamic acid or aminocaproic acid; for severe cases or surgery, FFP may be added. PMC+2rarecoagulationdisorders.org+2

5. Why do dental bleeds come back later?
   Because clots at moist mucosal sites can lyse early without A2AP; topical or oral TXA helps prevent this. PubMed

6. Can I get thrombolytic drugs (tPA) if I have a heart attack or stroke?
   This needs urgent specialist decision; tPA increases fibrinolysis and could cause severe bleeding in A2AP deficiency. Your medical alert ID is important. rarecoagulationdisorders.org

7. Is there a cure?
   No specific cure today. Management is preventive and supportive (antifibrinolytics, procedure planning). Gene therapy is not established for this condition.

8. Do I need genetic testing?
   It can confirm inherited disease and help with family counseling, especially if you plan children. Mayo Clinic Laboratories

9. What about pregnancy and childbirth?
   Plan early with obstetrics and hematology; antifibrinolytics and careful delivery planning lower risk.

10. Can children be affected?
    Yes; severe forms often show in childhood, including prolonged umbilical bleeding. NCBI

11. Are heterozygous carriers symptomatic?
    Many are mild or asymptomatic, but some bleed with surgery/dental work or as they age. rarecoagulationdisorders.org

12. What if my deficiency is acquired?
    Treat the underlying cause (liver, DIC, nephrotic syndrome) in addition to antifibrinolytics. rarecoagulationdisorders.org

13. Is aprotinin used?
    Occasionally in the OR or topically; systemic use is restricted and specialist-only due to risks.

14. Do vitamins fix the deficiency?
    No. Vitamins can support healing and anemia, but they do not replace A2AP or antifibrinolytics.

15. Who should coordinate my care?
    A hematologist, ideally at a Hemophilia Treatment Center, working with your dentists, surgeons, and primary doctor.
