Liver Function Profile Anomalies in HIV Seropositive Tuberculosis.

BACKGROUND The Human Immunodeficiency Virus (HIV) and the Tuberculosis (TB) co infection are contributory to each other in causing a progressive decline in the cell mediated immunity and a damage to the hepatobiliary system. The aim of our study was to estimate the extent of liver damage which was caused by these infections before the start of the therapy with hepatotoxic drugs like Antiretroviral Therapy (ART) and Antitubercular Drugs (ATD). METHODS One hundred and ninty three confirmed HIV positive cases were enrolled in this study. The cases were divided into 2 groups; Group 1-100 subjects with TB and Group 2-93 subjects without TB.80 age and sex matched controls were also included (Group 0). Some parameters of the serum Liver Function Test (LFT) were estimated biochemically by using an auto analyzer (ERBA XL600,Transasia). RESULTS The serum total bilirubin, Alanine Transaminase (ALT), Aspartate Transaminase (AST) and the Alkaline Phosphatase (ALK-P) levels were significantly higher in the cases as compared to those in the controls, more so in the cases with the associated TB co infection, except the AST levels. The Group 1subjects had lower serum total protein and albumin levels and altered albumin/globulin ratios as compared to the controls. A statistically significant difference was absent in the serum total protein levels between the Group 2 cases and the Group 0 controls. No significant differences were observed when the values for serum total protein, albumin and globulin and the albumin: globulin ratios among the two case groups (1 and 2) were compared. CONCLUSION The results have shown the importance of estimating some LFT parameters, prior to the start of ATD and ART in these cases. Hence, a mandatory performance of LFT is recommended, as it is simple and cost effective.
