    The effect of standard dose multivitamin supplementation on disease progression in HIV-infected adults initiating HAART: a randomized double blind placebo-controlled trial in Uganda
    (BioMed Central, 2015) Guwatudde, David; Wang, Molin; Ezeamama, Amara E.; Bagenda, Danstan; Kyeyune, Rachel; Wamani, Henry; Manabe, Yukari C.; Fawzi, Wafaie
    Background: Efficacy trials investigating the effect of multivitamin (MV) supplementations among patients on Highly Active Antiretroviral Therapy (HAART) have so far been inconclusive. We conducted a randomized, double blind, placebo controlled trial to determine the effect of one recommended daily allowance (RDA) of MV supplementation on disease progression in patients initiating HAART. Methods: Eligible subjects were randomized to receive placebo or MV supplementation including vitamins B-complex, C and E. Participants were followed for up to 18 months. Primary endpoints were: change in CD4 cell count, weight and quality of life (QoL). Secondary endpoints were: i) development of a new or recurrent HIV disease progression event, including all-cause mortality; ii) switching from first- to second-line antiretroviral therapy (ART); and iii) occurrence of an adverse event. Intent-to-treat analysis, using linear regression mixed effects models were used to compare changes over time in the primary endpoints between the study arms. Kaplan-Meier time-to-event analysis and the log-rank test was used to compare HIV disease progression events and all-cause mortality. Results: Four hundred participants were randomized, 200 onto MV and 200 onto placebo. By month 18, the average change in CD4 cell count in the MV arm was 141 cells/uL compared to 147 cells/uL in the placebo arm, a mean difference of −6 · 17 [95 % CI −29 · 3, 16 · 9]. The average change in weight in the MV arm was 3 · 9 kg compared to 3 · 3 kg in the placebo arm, a mean difference of 0 · 54 [95 % CI −0 · 40, 1 · 48]; whereas average change in QoL scores in the MV arm was 6 · 8 compared to 8 · 8 in the placebo arm, a mean difference of −2.16 [95 % CI −4 · 59,0 · 27]. No significant differences were observed in these primary endpoints, or in occurrence of adverse events between the trial arms. Conclusions: One RDA of MV supplementation was safe but did not have an effect on indicators of disease progression among HIV infected adults initiating HAART. Trial registration Clinical trials NCT01228578, registered on 15th October 2010.

    Depressive and Anxiety Symptoms Predict Sustained Quality of Life Deficits in HIV-Positive Ugandan Adults Despite Antiretroviral Therapy
    (Ovid Technologies (Wolters Kluwer Health), 2016) Ezeamama, Amara E; Woolfork, Makhabele N; Guwatudde, David; Bagenda, Danstan; Manabe, Yukari C; Fawzi, Wafaie; Smith Fawzi, Mary C
    The impact of psychosocial status at onset of antiretroviral therapy on changes in quality of life (QOL) and subjectively rated health (SRH) among adults on highly active antiretroviral therapy (HAART) in resource-limited settings is poorly understood. Therefore, we evaluate the association between stigma, anxiety, depression, and social support and change in QOL and SRH in HIV-infected Ugandan adults during an 18-month period.Psychosocial indicators were assessed at enrollment using structured questionnaires. QOL and SRH measures were assessed at months 0, 6, 12, and 18 using the Medical Outcomes Survey-HIV. Linear mixed models determined risk estimated differences in QOL and SRH in relation to quartiles of each psychosocial status indicator. Repeated measures generalized estimating equations modeling was implemented to assess differences in likelihood of improved versus nonimproved SRH during follow-up.QOL scores and SRH improved significantly for all participants over 18 months (P < 0.0001). The gain in QOL increased dose-dependently as baseline depressive symptoms (timedepression P < 0.001) and anxiety levels (timeanxiety P < 0.001) declined. Lower social support was associated with worse QOL at baseline (P = 0.0005) but QOL improvement during follow-up was not dependent on baseline level of social support (timesocial support P = 0.8943) or number of stigmatizing experiences (timestigma P = 0.8662). Psychosocial determinants did not predict changes in SRH in this study.High levels of depression and anxiety symptoms at HAART initiation predicts lower gains in QOL for HIV-positive patients for as long as 18 months. Long-term QOL improvements in HIV-infected adults may be enhanced by implementation of psychosocial interventions to reduce depression and anxiety in HIV-infected adults.
