Abstract

BACKGROUND:

Tuberculosis causes inflammation and muscle wasting. We investigated how attenuation of inflammation relates to repletion of body composition during treatment in an underserved population.

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.

RESULTS:

Weight increased by 3.02 ± 0.81 kg (5.5%; P = 0.007) at week 4 and by 8.59 ± 0.97 kg (15.6%; P < 0.0001) at week 24. Repletion of body mass was primarily fat, which increased by 2.09 ± 0.52 kg at week 4 and 5.05 ± 0.56 kg at week 24 (P = 0.004 and P < 0.0001 versus baseline). Fat-free mass (FFM), body cell mass (BCM), and phase angle did not increase until study week 8. Albumin rose to 3.65 ± 0.14 g/dL by week 4 (P < 0.001) and slowly increased thereafter. CRP levels declined by ∼50% at each interval visit.

CONCLUSIONS:

During the initial treatment, acute phase reactants returned towards normal. The predominant accrual of fat mass probably reflects ongoing, low levels of inflammation.
