Objective: To estimate serum vitamin A in pulmonary tuberculosis (PTB) patients at the start and end of anti-tuberculosis treatment.
Design: Serum vitamin A was estimated in 47 PTB patients (pre and post treatment), 46 healthy household contacts and 30 healthy ‘normals'.
Results: Mean serum vitamin A in patients at the start of treatment was 21.2 m g/dl, which was significantly lower than in household contacts (42.2 m g/dl) and healthy ‘normals' (48.1 m g/dl). The vitamin A levels in patients increased following treatment.
Conclusion : The low vitamin A levels observed in patients returned to normal at the end of anti-tuberculosis treatment without vitamin A supplementation.
