Severity of human immunodeficiency virus infection is associated with decreased phase angle, fat mass and body cell mass in adults with pulmonary tuberculosis infection in Uganda
S. Shah et al., Severity of human immunodeficiency virus infection is associated with decreased phase angle, fat mass and body cell mass in adults with pulmonary tuberculosis infection in Uganda, J NUTR, 131(11), 2001, pp. 2843-2847
Although coinfection with tuberculosis and human immunodeficiency virus (HI
V) is emerging as a major problem in many developing countries, nutritional
status has not been well characterized in adults with tuberculosis and HIV
infection. We compared nutritional status between 261 HIV-positive and 278
HIV-negative adults with pulmonary tuberculosis in Kampala, Uganda, using
anthropometry and bioelectrical impedance analysis. Among 163 HIV-positive
and 199 HIV-negative men, intracellular water-to-extracellular water (ICW:E
CW) ratio was 1.48 +/- 0.26 and 1.59 +/- 0.48 (P = 0.006) and phase angle w
as 5.42 +/- 1.05 and 5.76 +/- 1.30 (P = 0.009), respectively. Among 98 HIV-
positive and 79 HIV-negative women, ICW:ECW was 1.19 +/- 0.16 and 1.23 +/-
0.15 (P = 0.11) and phase angle was 5.35 +/- 1.27 and 5.43 +/- 0.93 (P = 0.
61), respectively. There were no significant differences in BMI, body cell
mass, fat mass or fat-free mass between HIV-positive and HIV-negative adult
s. Among HIV-positive subjects, BMI, ICW:ECW, body cell mass, fat mass and
phase angle were significantly lower among those with CD4(+) lymphocytes le
ss than or equal to 200 cells/muL compared with those who had > 200 cells/m
uL. In sub-Saharan Africa, coinfection with pulmonary tuberculosis and HIV
is associated with smaller body cell mass and intracellular water, but not
fat-free mass, and by large differences in ICW:ECW and phase angle alpha.
