SETTING: A metropolitan governmental medical centre, Seoul, Republic of Korea. OBJECTIVE: To elucidate the impact of the nutritional deficit assessed by the Nutritional Risk Score (NRS) on the outcomes of in-patients with pulmonary tuberculosis (PTB). DESIGN: All hospitalised patients with microbiologically confirmed PTB were enrolled. A four-point NRS included low body mass index (<18.5 kg/m2), hypoalbuminaemia (<30.0 g/l), hypocholesterolaemia (<2.33 mmol/l) and severe lymphocytopaenia (<7 × 105 cells/l). The primary outcome was overall in-hospital mortality. The degree of radiographical resolution after anti-tuberculosis treatment was also evaluated. RESULTS: In a total of 156 patients, the male to female ratio was 1.6:1. The overall mortality was 13.5% and tuberculosis- specific fatality was 3.9%. Predisposing factors and high NRS (≥3 points) were independent risk factors for in-hospital death after adjusting for the severity of PTB. High NRS (OR = 16.8, P < 0.001) and predisposing factors (OR = 5.4, P = 0.032) were independent risk factors for 30-day survival. The NRS was not associated with radiographic improvement. CONCLUSION: Regardless of disease severity, the high NRS was a significant negative predictor among in-patients with PTB; this finding should therefore be considered in the management of PTB despite the current era of effective anti-tuberculosis chemotherapy.
