We report the first case of young woman with the p phenotype and anti-PP1P(k) antibody in the Malaysian population who was identified during a blood grouping and antibody screening procedure after her first miscarriage. Further family screening detected two other siblings who possessed the same rare phenotype and antibody. Because of difficulties in finding compatible units in the local population, the patient and her two siblings were advised to become regular blood donor. Their blood was frozen for future use. After she had two recurrent miscarriages, her third pregnancy was successfully managed using oral dydrogesterone, which was started from 10 weeks into the pregnancy. Her pregnancy was uneventful and she gave birth to a healthy term neonate.
Plateletpheresis is a method used to remove platelet from the body either from random volunteer donors, patient's family members or HLA matched donors. A cross sectional study was carried out on 59 plateletpheresis donors aged between 18 and 55 years at National Blood Center (NBC), Kuala Lumpur. We compared the blood parameters before and after plateletpheresis and we found that the platelet count, FVIII, fibrinogen and thrombophilia markers anti-thrombin (AT), protein C and protein S were significantly reduced (p<0.05) with prolonged PT and APTT. There were significant changes in blood coagulation parameters but it is within acceptable range.
