Multi drug therapy effects on routine laboratory parameters in Leprosy patients

Background: Multi Drug Therapy approved by WHO is the best treatment option for Leprosy. There is a significant decline of mortality and morbidity after the introduction of multi drug therapy. But the adverse effects causing changes in clinical and laboratory parameters to multi drug therapy are the main limiting obstacle for the treatment course completion. Objective: The aim of this study is to find out the effects on routine laboratory parameters including hematological and biochemical changes before, during and after the treatment of multi drug therapy in leprosy. Methodology: A descriptive cohort hospital based study on 85 multi drug therapy treated leprosy patients using standard laboratory tools for routine investigations for 18 months. Results: During the one year multidrug treatment period, most of the routine laboratory parameters showed mild to moderate change from normal level during the first 3 months with gradual recovery in the following months. Complete blood count assessment revealed mild decline in Hb, PCV, MCH, MCHC, and moderate decline in WBC and Platelet count. A mild increase in liver function tests (Bilirubin, AST, ALT, Alkaline phosphatase) and renal function tests (S.Creatinine, b. Urea) was observed. A moderate decline in S. Sodium with mild increase in S. Potassium was found on investigating S. Electrolytes. Patients were fully recovered from all hemato-biochemical adverse effects after 6 months of completion of the multi drug therapy. Conclusion: Despite of mild to moderate hematological and biochemical adverse reactions with multi drug therapy, recovery was excellent after 6 months of completion of therapy
