We report a retrospective series of 100 non-HIV adult patients with miliary tuberculosis (MTB) treated in a tertiary care centre. There were 51 males. Their mean age was 35 years. Predisposing conditions existed in 34. Twelve patients had larger-than-miliary (>2mm) shadows in their chest roentgenograms. Five presented with acute respiratory failure, and early treatment cured four of them. Hyponatraemia occurred in 42/60 patients (70%) for whom values were available. Twelve patients (12%) died of MTB. Temperature ≥39.3°C (p<0.01), hypoalbuminaemia (p<0.01), hyponatraemia (p< 0.001), history of vomiting (p< 0.001) and presence of crepitations on auscultation (p< 0.001) were independent predictors of mortality. Diagnosis of MTB is difficult even in an endemic area, as the clinical symptoms are non-specific and the chest roentgenograms do not always reveal classical miliary changes. A high index of clinical suspicion and diligent efforts in confirming the diagnosis are needed, as early therapy yields good results.
