Design. Twenty-four patients (23 to 79 years old) with pulmonary tuberculosis and inflammation (pretreatment albumin = 2.96 ± 0.13 g/dL, C-reactive protein [CRP] = 6.71 ± 1.34 μg/dL, and beta-2-microglobulin = 1.68 ± 0.10 μg/L) were evaluated and had BIA over 24 weeks. This evidence concerns the gene B2M and pulmonary tuberculosis.
