    Lean Tissue Mass Wasting is Associated With Increased Risk of Mortality Among Women With Pulmonary Tuberculosis in Urban Uganda
    (Elsevier Inc., 2012) Mupere, Ezekiel; Malone, Lashaunda; Zalwango, Sarah; Chiunda, Allan; Okwera, Alphonse; Parraga, Isabel; Stein, Catherine M.; Tisch, Daniel J.; Mugerwa, Roy; Boom, W. Henry; Mayanja, Harriet; Whalen, Christopher C.
    OBJECTIVES: We assessed the impact of wasting on survival in patients with tuberculosis by using a precise height-normalized lean tissue mass index (LMI) estimated by bioelectrical impedance analysis and body mass index (BMI). METHODS: In a retrospective cohort study, 747 adult pulmonary patients with tuberculosis who were screened for HIV and nutritional status were followed for survival. RESULTS: Of 747 patients, 310 had baseline wasting by BMI (kg/m2) and 103 by LMI (kg/m2). Total deaths were 105. Among men with reduced BMI, risk of death was 70% greater (hazard ratio [HR] 1.7, 95% confidence interval [95% CI] 1.03–2.81) than in men with normal BMI. Survival did not differ by LMI among men (HR 1.1; 95% CI 0.5–2.9). In women, both the BMI and LMI were associated with survival. Among women with reduced BMI, risk of death was 80% greater (HR 1.8; 95% CI 0.9–3.5) than in women with normal BMI; risk of death was 5-fold greater (HR 5.0; 95% CI 1.6–15.9) for women with low LMI compared with women with normal LMI. CONCLUSIONS: Wasting assessed by reduced BMI is associated with an increased risk for death among both men and women whereas reduced LMI is among women with tuberculosis.

    Quality of life and social support among patients receiving antiretroviral therapy in Western Uganda
    (Informa UK Limited, 2009-03) Bajunirwe, Francis; Tisch, Daniel J.; King, Charles H.; Arts, Eric J.; Debanne, Sara M.; Sethi, Ajay K.
    Quality of life (QOL) among patients with HIV/AIDS has been shown to improve once treatment with antiretroviral therapy (ART) has been initiated. We conducted a cross-sectional study in Western Uganda to examine the factors associated with QOL among patients who had received ART for the duration of at least six months. We interviewed 330 patients attending the HIV/AIDS clinic at two government-supported hospitals in Western Uganda. We measured QOL using a culturally adapted version of the Medical Outcomes Study (MOS-HIV) tool and calculated the physical health summary (PHS) and mental health summary (MHS) scores. In addition, data were collected on sociodemographic factors, three-day self-reported adherence, social support, sexual behavior, CD4 count and viral load. Informational social support was significantly positively correlated with PHS (p=0.001) and MHS (p=0.002). Affectionate support was also significantly positively correlated to PHS (p=0.05) and MHS (p=0.03) but tangible support was not (PHS p value=0.85 and MHS p value=0.31). In the univariate analysis, older age, rural dwelling, alcohol use, CD4 count less than 200, and ART duration of less than one year were significantly associated with lower PHS scores. Lower PHS scores were also associated with sexual inactivity. In multivariate analysis, higher scores on informational social support and CD4≥200 were associated with higher PHS score and past or recent alcohol consumption was associated with lower scores on MHS. Optimizing ART to restore CD4 count and provision of informational and affectionate social support but not tangible support, to HIV/AIDS patients may improve their QOL.
