Frequency & comparison of Thrombocytopenia in patients Suffering from P. Vivax and P. Falciparum (A study at Diagnostic Research Center in KPK).
Ophthalmol Update Jan ;16(1):528-32.

Background: Malaria is a life threatening infectious disease and in severe cases is associated with calamitous complications. It is usually manifested with abnormalities in various hematological indices with anemia and thrombocytopenia being the most frequent ones. The present study throws light on the frequency of thrombocytopenia in patients suffering from P.Vivax and P. Falciparum malaria and provides comparison with the available literature worldwide. Methodology: The study was carried out as cross-sectional study at OK Diagnostic Lab & Research Center in Peshawar from October 2013 to October 2016. Result: All malaria parasite (MP) positive cases reported during the study period were included making a total of 136 MP positive cases. Platelets counts in all these patients were analyzed according to WHO criteria. Thrombocytopenia was defined as platelet count of < 150 � 103 /cmm. Among 136 MP positive patients, 74 (55.4%) had associated thrombocytopenia on peripheral blood smear. Conclusion: Thrombocytopenia was associated with P. vivax infection in 71.4 % cases in contrast to P. falciparum infection, where as 26 % cases had associated thrombocytopenia (p = 0.01).
