Effects of malaria parasitaemia on some haemostatic parameters among pregnant women of African descent in Specialist Hospital Sokoto, Nigeria.

ABSTRACT

BACKGROUND: Malaria in pregnancy is a major contributor to adverse maternal and prenatal outcome. In hyper endemic areas like ours, it is a common cause of anaemia in pregnancy and is aggravated by poor socioeconomic circumstance. This study evaluated the prothrombin time and activated partial thromboplastin time of malaria parasitized pregnant women. METHOD: A total of 90 pregnant women participated in the study, 60 of which were malaria positive and 30 of which were malaria negative. Participants were recruited from the antenatal Clinic of Specialist Hospital Sokoto, Nigeria. A structured interviewer-administered questionnaire was used to obtain some socio-demographic characteristics of subjects. Blood samples were collected in ethylene diamine tetra acetic acid and examined for malaria parasite and platelet count while citrated samples were used for the determination of some haemostatic parameters (prothrombin time and activated partial thromboplastin time). Data generated was analyzed using SPSS 25.0 statistical package. A p-value ⩽ 0.05 was considered significant in all statistical comparisons. RESULT: There was a statistically significant decrease (p= 0.000) in the platelet counts of the parasitized subjects compared to the non-parasitized controls. We observed a significant prolongation on both the prothrombin time and activated partial thromboplastin time among the parasitized subjects compared to the non-parasitized controls (p= 0.000). CONCLUSION: This study has shown that malaria in pregnancy causes a significant decrease in the platelet count and prolongation in the prothrombin (PT) and the activated partial thromboplastin time (APTT). There is need for the malaria and haemostatic parameters to be assayed routinely on pregnant women particularly those presenting to antenatal clinic with febrile illness.
