    https://doi.org/10.1111/ajo.13303

    Causes

    • Gestational (70-80%)
    • Primary immune thrombocytopenia (ITP) (1-2%)
    • Secondary ITP, eg due to human immunodeficiency virus (HIV), hepatitis C, systemic lupus erythematosus
    • Congenital
    • Drug-induced
    • Type IIb von Willebrand’s disease (VWD)
    • Antiphospholipid syndrome
    • Splenic sequestration, eg liver disease, portal hypertension
    • Bone marrow disorders
    • Nutritional deficiency, eg vitamin B12/folate
    • Pregnancy-associated microangiopathy
      • Preeclampsia/haemolysis, elevated liver enzymes, low platelets syndrome (HELLP)
      • Thrombotic thrombocytopenic purpura (TTP)
      • Haemolytic uraemic syndrome (HUS)
      • Acute fatty liver of pregnancy
      • Sepsis
      • DIC
      • Spurious/Pseudothrombocytopenia (clumping)


        • Initial investigations (if platelet count <70)

        • Full blood count and reticulocyte count
        • Peripheral blood film
        • Optical platelet count (if available)
        • Coagulation screen
        • Renal and liver function tests
        • Thyroid function tests
        • Direct Coombs test
        • Antiphospholipid antibodies: lupus anticoagulant, anticardiolipin antibodies, beta 2 glycoprotein 1 antibodies
        • Antinuclear antibody (ANA)
        • Hepatitis B/C and human immunodeficiency virus (HIV) serology
        • Helicobacter pylori
        • Vitamin B12/folate
        • Immunoglobulins


          • Management

          • Monthly platelet count in pregnancy, fortnightly if <100 from 36 weeks
          • Withhold aspirin if platelets <50
          • IM injections contraindicated if platelets <50 (Give IV Rhophylac instead of Anti-D)
          • Treatment indications: Platelets <20, Bleeding attributed to low platelets, Platelets <50 and pre-procedure (surgery/CVS)/birth imminent/planning neuraxial anaesthesia with platelets <70


            • Regimens

            • IVIG and prednisone are equally effective first-line treatments
              • Start with 20-25 mg prednisone PO daily
              • 40-50 mg prednisone PO daily for platelets <20 or acute bleeding
              • Response takes 4-28 days
              • Prednisone side effects: GDM exacerbation, hypertension, poor sleep, gastritis, mood disturbance
              • IVIG indicated for life-threatening haemorrhage around delivery
              • 1-2 g/kg as single or divided dose
              • Response 2-7 days
              • Adverse effects: transfusion reaction, headache, aseptic meningitis, thrombosis


                • Labour and birth

                • Platelets <100: MDT approach, Birth in hospital, Induce at term
                • Target platelets >50 for: Vaginal birth, Instrumental, Caesarean, Clexane use
                • Target platelets >70 for allow regional anaesthesia (spinal is less traumatic than epidural)
                • Stress steroids in labour: IV hydrocortisone 50 mg Q6H from established labour to 6 hours after birth. For caesarean, give 100 mg IV hydrocortisone at time of anaesthesia, then 6 hours post-birth
                • Mode of birth: Lack of data to inform instrumental risks. ITP is associated with a small increase in neonatal thrombocytopaenia.
