Résumé
Falciparum malaria is responsible for 1-3 million deaths annually worldwide. Liver involvement is common and may manifest as raised serum bilirubin, hepatomegaly and elevated liver enzymes. Unconjugated hyperbilirubinemia is usually seen leading to increased mortality. Alanine aminotransferase [SGPT] is a marker of liver damage. The present study was conducted on Plasmodium falciparum malarial patients to observe the correlation between liver enzymes and bilirubin. To observe the correlation coefficient of bilirubin with liver enzymes [SGPT, SGOT and Alkaline Phosphatase] in patients of falciparum malaria. A Descriptive study. Department of Biochemistry, Basic Medical Sciences Institute, JPMC, Karachi from August 2005 to July 2006. Total 81 patients of different ages and both sexes suffering from acute malaria, were selected by convenient sampling. Nine patients, infected by Hepatitis B and C infections were excluded from the study. Among remaining 72 cases, 48 [70%] were suffering from infection by Plasmodium falciparum and 24 [30%] from infection by Plasmodium vivax infection. The Falciparum infected patients were equally divided into two groups on the basis of duration of illness. Group I having 1- 7days illness and Group II having duration of 8-20 days. Patients suffering from plasmodium vivax infection and illness of 1 - 20 days were placed in Group III. In the group I, SGPT and Alkaline phosphatase showed a statistically significant positive correlation r=0.50 and r=0.054, respectively with bilirubin [P<0.05]. In group II, the SGPT showed a statistically excellent positive correlation [r=0.88; P<0.01], while the SGOT and Alkaline phosphatase also showed a statistically significant positive correlation. In group III both aminotransferases and Alkaline phosphatase showed a statistically significant positive correlation r=0.82, 0.63 and 0.69 respectively. Positive correlation of liver enzymes and bilirubin shows that liver function tests should be performed along with early diagnosis of Plasmodium falciparum malarial infections in order to prevent complications and to reduce mortality
