Introduction: *Work attributed to Department of Pediatric Orthopaedics, Chacha Nehru Bal Chikitsalaya, Geeta Colony, Delhi-110031(India)This study tested the hypothesis whether the lymphocyte/monocyte ratio (L/M ratio) altered significantly during treatment of paediatric osteoarticular tuberculosis (OATB) for it to be a useful monitor of the response to therapy.
Material And Methods: Thirty immunocompetent paediatric patients with OATB treated with 6 months of uninterrupted multidrug anti-tubercular treatment with resultant clinical and radiological healing of the lesion were included. Haemoglobin, total leucocyte, monocyte and lymphocyte count, and erythrocyte sedimentation rate (ESR) were collected at 0, 2 and 6 months, and were analysed.
