Objective: To determine the role of the IL8 rs4073 polymorphism in predicting the risk of central nervous system (CNS) toxicity in patients receiving standard pharmacological treatment for multidrug-resistant tuberculosis (MDR-TB)., Methods: A cohort of 85 consenting MDR-TB patients receiving treatment with second-line antituberculosis drugs had their blood samples amplified for the IL8 (rs4073) gene and genotyped. All patients were clinically screened for evidence of treatment toxicity and categorized accordingly. Crude and adjusted associations were assessed., Results: The chief complaints fell into the following categories: CNS toxicity; gastrointestinal toxicity; skin toxicity; and eye and ear toxicities. Symptoms of gastrointestinal toxicity were reported by 59% of the patients, and symptoms of CNS toxicity were reported by 42.7%. With regard to the genotypes of IL8 (rs4073), the following were identified: AA, in 64 of the study participants; AT, in 7; and TT, in 11. A significant association was found between the dominant model of inheritance and CNS toxicity for the crude model (p = 0.024; OR = 3.57; 95% CI, 1.18-10.76) and the adjusted model (p = 0.031; OR = 3.92; 95% CI, 1.13-13.58). The AT+TT genotype of IL8 (rs4073) showed a 3.92 times increased risk of CNS toxicity when compared with the AA genotype., Conclusions: The AT+TT genotype has a tendency to be associated with an increased risk of adverse clinical features during MDR-TB treatment.

It was observed that liver enzymes are elevated in dengue fever. In this study our aims were to determine the changes in serum transaminases in dengue fever, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) and to find out the relation of transaminase level changes with the disease severity. This cross sectional, prospective hospital based observational study was carried out in the department of Gastrointestinal Hepatobiliary and Pancreatic diseases and Internal Medicine department of BIRDEM Hospital, Dhaka. Patients are classified into 3 groups depending on clinical & laboratory findings: Group 1 dengue fever (DF), Group 2 dengue hemorrhagic fever & Group 3 dengue shock syndrome. A total of 240 cases were taken in this study who fulfilled the selection criteria. Out of whom 125 male and 115 female patients. DF was 157(65.4%) & DHF was 83(34.6%). Aminotransferases [aspartate aminotransferase (AST) and alanine aminotransferase (ALT)] were significantly raised in DHF cases compared to those of classical dengue fever (AST 84.5±42.4 in DF vs. 507±106.8 IU/L in DHF and ALT 59.9±31.3 in DF vs. 234±30.6 IU/L in DHF). The rise of AST is far greater than ALT in both DF and DHF. Dengue fever is usually associated with mild to moderate elevations of aminotransferase levels. The increase in aminotransferases, mainly AST has been associated with disease severity and serves as an early indicator of dengue infection.
