  1. Women with Bleeding Disorders Nairobi, Kenya June 25, 2013

  2. Objectives Discuss the types of bleeding disorders affecting women Distinguish sex-linked inheritance from autosomal inheritance Explain carrier versus non-carrier states in women List common bleeding symptoms in women Identify approaches available to treat bleeding in women Examine ways to treat bleeding episodes specific to women

  3. Types of Bleeding Disorders in Women Hemophilia: very rare, more commonly symptomatic carrier Von Willebrand disease Other plasma protein (factor) deficiencies Platelet function defects Fibrinolysis inhibitor deficiencies Hereditary hemorrhagic telangiectasia (HHT) Ehlers-Danlos Additional text example

  4. Carriers of hemophilia For many years, people believed that only men could have symptoms of hemophilia We now know that women who carry the hemophilia gene can experience symptoms. A woman with < 40% factor levels is no different from a man with the same factor levels—she has hemophilia A woman with levels of 40-60% who experiences abnormal bleeding is called a symptomatic carrier

  5. Carrier versus Non-Carrier Can occur on sex chromosomes and autosomes Trait generally not expressed in carriers Level of missing protein in carriers can be quite low; even in the mild range Some carriers may be symptomatic Remember: all daughters born to men with hemophilia are obligate carriers.

  6. Plasma protein deficiencies Sometimes called rare bleeding disorders (RBDs)1 or recessively-inherited coagulation defects (RICDs)2 Differ from hemophilia A & B1,2,3 • Genetics • Epidemiology • Clinical presentation • Diagnostic evaluation • Treatment May lack specific protein concentrate for treatment • 1Bolton-Maggs PHBetal. Haemophilia2004; 10: 593-628. • 2Mannucci PM, Duga S, Peyvandi F. Blood2004; 104: 1243-1252. • 3Munn, James E. Nursing Care of Children and Adolescents with Cancer and Blood Disorders, Fourth Edition, Glenview, IL; Association of Pediatric Hematology Oncology Nurses; 2011: 818-876.

  7. Platelet Disorders GiulioBizzozero discovered function of platelets in 1882 Role of platelets in hemostasis: • Primary hemostatic plug • Secretion of substances to promote • Platelet recruitment • Vessel contraction • Coagulation • Provide optimal surface for coagulation to proceed GiulioBizzozero • Munn, James E. Nursing Care of Children and Adolescents with Cancer and Blood Disorders, Fourth Edition, Glenview, IL; Association of Pediatric Hematology Oncology Nurses; 2011: 818-876.

  8. Platelets Normal: 150-450 X 103 Average life span: 7-10 days 1/3 pooled 2/3 in circulation Megakaryocyte Spleen • Munn, James E. Rare Coagulopathies. In: National Hemophilia Foundation’s Nursing Working Group (ed): Nurses’ Guide to Bleeding Disorders, in print.

  9. Platelet Disorders Defects in any of the functions of platelets can result in bleeding Clinical features: easy bruising, petechiae, mucocutaneous bleeding, menorrhagia, rarely intramuscular bleeding or hemarthrosis Diagnosis: CBC with differential and platelet count, PFA testing, platelet aggregation and secretion studies, electron microscopy Treatment • Antifibrinolytics (IV, oral) • Hormonal suppression (OCPs, IUD) • Platelets • Recombinant activated factor VII • Munn, James E. Rare Coagulopathies. In: National Hemophilia Foundation’s Nursing Working Group (ed): Nurses’ Guide to Bleeding Disorders, in print.

  10. Fibrinolysis Inhibitor Protein Deficiencies Fibrinolysis is the body’s natural response to clot formation Achieved principally through plasmin (enzyme that degrades clots) Natural inhibitors help regulate this process • α2-antiplasmin (α2-AP) • Plasminogen activator inhibitor-1 (PAI-1) Deficiencies in either can result in bleeding Clinical bleeding is usually mucocutaneous Treatment with antifibrinolytics (IV, oral) • Munn, James E. Rare Coagulopathies. In: National Hemophilia Foundation’s Nursing Working Group (ed): Nurses’ Guide to Bleeding Disorders, in print.

  11. Other bleeding Disorders Hereditary hemorrhagic telangiectasia (HHT) (Osler-Weber-Rendu Syndrome) • AVMs present in mucosal membranes and may involve other organs • Bleeding can be mild or severe • Treatment is symptomatic 1Dupuis-Girod S, Bailly S, PlauchuH. J ThrombHaemost 2010; 8: 1447–1456.

  12. Other bleeding Disorders Ehlers-Danlos Syndrome (EDS) • Connective tissue (collagen) defect • Clinical features • Joint hypermobility • Skin hyperelasticity • Hypertrophic scarring • Bruising, spontaneous joint subluxations, poor wound healing • Treatment is geared toward prevention or is symptomatic2 • 2Faber P, Craig WL, Duncan JL, Holliday K. ActaAnaesthesiolScand 2007; 9: 1277-1279. • 3Munn, James E. Rare Coagulopathies. In: National Hemophilia Foundation’s Nursing Working Group (ed): Nurses’ Guide to Bleeding Disorders, in print.

  13. Inheritance of Bleeding Disorders Sex-linked: hemophilia, Wiskott-Aldrich Syndrome (platelet disorder) Autosomal: VWD, other factor deficiencies, most platelet disorders, fibrinolysis inhibitor deficiencies, HHT, Ehlers-Danlos • Dominant • Recessive • Heterozygous • Homozygous

  14. Common Bleeding Symptoms in Women with Bleeding Disorders Mucocutaneous bleeding Petechiae Easy bruising Bleeding after trauma or surgery (including dental procedures) Menorrhagia Post-partum hemorrhage Rarely, intramuscular bleeding or hemarthrosis

  15. Treatment for Bleeding • Avoid IM injections if possible • Avoid ASA and ASA-containing products • Prepare for surgeries/deliveries in advance • No invasive procedures without consultation of HTC team

  16. Menorrhagia Excessive uterine bleeding occurring at the expected intervals of the menstrual periods. The bleeding from the uterus starts on schedule but is heavier than usual and may last longer than usual. Menorrhagia may be a sign of an underlying disorder, such as hormone imbalance, endometriosis, uterine fibroids or, rarely, cancer of the uterus. “MedicineNet.com” – We bring doctors’ knowledge to you. http://www.medterms.com/script/main/art.asp?articlekey=4353

  17. Menorrhagia Common symptom of women with bleeding disorders1 Obstetricians/gynecologists may not associate menorrhagia with an inherited bleeding disorder2 May result in unnecessary surgery if not treated appropriately Remember: the index patient identified by Erik von Willebrand in his discovery of a new bleeding disorder was a young girl who eventually died of hemorrhage in her 4th menstrual cycle3 1NHF “For You and Your Doctor” pamphlet (2001). 2Dilley, A., et al (2001) “Obst. And Gyn: 97 (4), 630-636. April. 3von Willebrand, E. (1926)

  18. Treatment of Menorrhagia DDAVP Antifibrinolytics Oral contraceptive pills Factor replacement/Blood products IUDs Surgical interventions

  19. Treatment of Excessive Menorrhagia • OCP “Formula” to stop recalcitrant menorrhagia Lo-ovral: • 1 pill QID x 2 days • 1 pill TID x 3 days • 1 pill BID x 4 days • Resume suppression therapy, usually 1-2 pills per day • Use of anti-emetics, analgesics a must

  20. Obstetrical/Post-partum Bleeding Treatment For the mother: Previous bleeding history and response to therapy usually best indicator of OB/post-partum bleeding/treatment Consider treatment at delivery and again at days 5-7 Factor concentrates to raise factor levels to >30% DDAVP – give immediately after delivery or at delivery of baby’s head NSVD is fine; consider cesarean for known carriers

  21. Obstetrical/Post-partum Bleeding For the baby: • Avoid suction or forceps delivery and fetal scalp monitoring • Take cord blood samples to avoid venipuncture bleeding • Consider cranial ultrasound in boys suspected to have hemophilia prior to discharge from hospital • Pediatrician should be available

  22. Summary Women may have a variety of bleeding disorders that require specialized care Inheritance patterns are different for different bleeding disorders Carriers may be symptomatic and require treatment for bleeding Menorrhagia is one of the most common bleeding manifestations in women Treatments are available Special care must be taken with pregnancy and delivery
