    Alcohol Use and HIV Disease Progression in an Antiretroviral Naïve Cohort
    (Journal of acquired immune deficiency syndromes, 2018) Hahn, Judith A.; Cheng, Debbie M.; Emenyonu, Nneka I.; Lloyd-Travaglini, Christine; Fatch, Robin; Shade, Starley B.; Ngabirano, Christine; Adong, Julian; Bryant, Kendall; Muyindike, Winnie R.; Samet, Jeffrey H.
    Alcohol use has been shown to accelerate disease progression in experimental studies of simian immunodeficiency virus in macaques, but the results in observational studies of HIV have been conflicting. We conducted a prospective cohort study of the impact of unhealthy alcohol use on CD4 cell count among HIV-infected persons in southwestern Uganda not yet eligible for antiretroviral treatment (ART). Unhealthy alcohol consumption was 3-month Alcohol Use Disorders Identification Test – Consumption (AUDIT-C) positive (≥3 for women, ≥4 for men) and/or phosphatidylethanol (PEth - an alcohol biomarker) ≥50 ng/ml, modeled as a time-dependent variable in a linear mixed effects model of CD4 count.

    Under-reporting of alcohol use by HIV-infected patients could adversely impact clinical care. This study examined factors associated with under-reporting of alcohol consumption by patients who denied alcohol use in clinical and research settings using an alcohol biomarker. We enrolled ARTnaïve, HIV-infected adults at Mbarara Hospital HIV clinic in Uganda. We conducted baseline interviews on alcohol use, demographics, Spirituality and Religiosity Index (SRI), health and functional status; and tested for breath alcohol content and collected blood for phosphatidylethanol (PEth), a sensitive and specific biomarker of alcohol use. We determined PEth status among participants who denied alcohol consumption to clinic counselors (Group 1, n = 104), and those who denied alcohol use on their research interview (Group 2, n = 198). A positive PEth was defined as ≥8 ng/ml. Multiple logistic regression models were used to examine whether testing PEth-positive varied by demographics, literacy, spirituality, socially desirable reporting and physical health status. Results showed that, among the 104 participants in Group 1, 28.8% were PEth-positive. The odds of being PEth-positive were higher for those reporting prior unhealthy drinking (adjusted odds ratio (AOR): 4.7, 95% confidence interval (CI): 1.8, 12.5). No other factors were statistically significant. Among the 198 participants in Group 2, 13.1% were PEth-positive. The odds of being PEth-positive were higher for those reporting past unhealthy drinking (AOR: 4.6, 95% CI: 1.8, 12.2), the Catholics (AOR: 3.8, 95% CI: 1.3, 11.0) compared to Protestants and lower for the literate participants (AOR: 0.3, 95% CI: 0.1, 0.8). We concluded that under-reporting of alcohol use to HIV clinic staff was substantial, but it was lower in a research setting that conducted testing for breath alcohol and PEth. A report of past unhealthy drinking may highlight current alcohol use among deniers. Strategies to improve alcohol self-report are needed within HIV care settings in Uganda.

    The relationship between spirituality/religiousness and unhealthy alcohol use among HIV-infected adults in southwestern Uganda
    (AIDS and Behavior, 2018) Adong, Julian; Lindan, Christina; Fatch, Robin; Emenyonu, Nneka I.; Muyindike, Winnie R.; Ngabirano, Christine; Winter, Michael R.; Lloyd-Travaglini, Christine; Samet, Jeffrey H.; Cheng, Debbie M.; Hahn, Judith A.
    HIV and alcohol use are two serious and co-existing problems in sub-Saharan Africa. We examined the relationship between spirituality and/or religiousness (SR) and unhealthy alcohol use among treatment-naïve HIV-infected adults attending the HIV clinic in Mbarara, Uganda. Unhealthy alcohol was defined as having either an Alcohol Use Disorders Identification Test – Consumption score of ≥4 for men or ≥3 for women, or having a phosphatidylethanol level of ≥50ng/ml based on analysis of dried blood-spot specimens. Of the 447 participants, 67.8% were female; the median age was 32 years (interquartile range [IQR]: 27–40). About half reported being Protestant (49.2%), 35.1 % Catholic, and 9.2% Muslim. The median SR score was high (103 [IQR: 89–107]); 43.3% drank at unhealthy levels. Higher SR scores were associated with lower odds of unhealthy drinking (adjusted odds ratio [aOR]: 0.83 per standard deviation [SD] increase; 95% confidence interval [CI] 0.66–1.03). The “religious behavior” SR sub-scale was significantly associated with unhealthy alcohol use (aOR: 0.72 per SD increase; 95% CI 0.58–0.88). Religious institutions, which facilitate expression of religious behavior, may be helpful in promoting and maintaining lower levels of alcohol use.
