Abstract
INTRODUCTION: HIV infection is known to cause coagulation abnormalities by various mechanism, especially during its late course. AIM: The objective of this study was to analyse platelet count, prothrombin time and activated partial thromboplastin time among HIV infected patients and to analyse these parameters with respect to their CD4 count and ART status. MATERIALS AND METHODS: A case control study was conducted with 120 HIV infected patients and 40 normal individuals. The blood samples were collected after obtaining consent from the subjects. The blood samples were processed for platelet count, prothrombin time and activated partial thromboplastin time and CD4 count. The results were tabulated and analysed with statistical package. RESULTS: The platelet count was significantly decreased in HIV infected patients compared to controls. Though HIV patients with CD4 count less than 200cells/mm(3) showed a decreased platelet count compared to those with CD4 count greater than 200cells/mm(3), it was not statistically significant. Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) was significantly prolonged in HIV patients, but only aPTT showed significant inverse correlation with CD4 count. None of the parameters showed statistical significance on comparing HIV patients on ART with those not on ART. CONCLUSION: Basic coagulation tests like platelet count, PT and especially aPTT can be used as prospective screening test to assess severity in HIV patients in resource limited settings where CD4 count is not available.
