Hematological parameters of human immunodeficiency virus positive pregnant women on antiretroviral therapy in Aminu Kano Teaching Hospital Kano, North Western Nigeria.

CONTEXT: Human immunodeficiency virus (HIV) scourge continues to affect young women within the reproductive age group and pregnancy is a recognized indication for the use antiretroviral (ARV) drugs among HIV-positive women. AIMS: The aim is to determine the combined effect of pregnancy, HIV and ARV drugs on the hematological parameters of the pregnant women. SETTINGS AND DESIGN: This was a comparative cross-sectional study conducted among 70 each of HIV-positive and negative pregnant women. SUBJECTS AND METHODS: Bio-demographic and clinical data were extracted from the client folder and 4 ml of blood sample was obtained from each participant. Full blood count was generated using Swelab automatic hematology analyzer while reticulocyte count and erythrocyte sedimentation rate (ESR) were conducted manually. STATISTICAL ANALYSIS USED: Data analysis was performed using SPSS version software 16 while P < 0.05 was considered statistically significant. RESULTS: Pregnant women with HIV had statistically significant lower hematocrit and white blood cell (WBC) and higher ESR than pregnant women without HIV (P < 0.000). There was no statistically significant difference between the two groups in terms of platelet and reticulocyte (P > 0.05). However, among HIV positive pregnant women, those with CD4 count < 350/mu L had statistically significant lower WBC and lymphocyte count than those with CD4 count >= 350/mu L (P < 0.05), whereas, those on zidovudine (AZT)-containing treatment had statistically significant lower hematocrit and higher mean cell volume than those on non-AZT-containing treatment (P < 0.05), but there was no statistically significant difference in any of the hematological parameters (P > 0.050) between women on first- and second-line ARV regimens. CONCLUSIONS: There is a significant difference in terms of hematological parameters between HIV-positive and HIV-negative pregnant women in this environment.
