1.  Improvement in Posttraumatic Stress Disorder in Postconflict Rwandan Women 
Journal of Women's Health  2011;20(9):1325-1332.
Abstract
Background
Depression and posttraumatic stress disorder (PTSD) are common in developing and postconflict countries. The purpose of this study is to examine longitudinal changes in PTSD in HIV-infected and uninfected Rwandan women who experienced the 1994 genocide.
Methods
Five hundred thirty-five HIV-positive and 163 HIV-negative Rwandan women in an observational cohort study were followed for 18 months. Data on PTSD symptoms were collected longitudinally by the Harvard Trauma Questionnaire (HTQ) and analyzed in relationship to demographics, HIV status, antiretroviral treatment (ART), and depression. PTSD was defined as a score on the HTQ of ≥2.
Results
There was a continuing reduction in HTQ scores at each follow-up visit. The prevalence of PTSD symptoms changed significantly, with 61% of the cohort having PTSD at baseline vs. 24% after 18 months. Women with higher HTQ score were most likely to have improvement in PTSD symptoms (p<0.0001). Higher rate of baseline depressive symptoms (p<0.0001) was associated with less improvement in PTSD symptoms. HIV infection and ART were not found to be consistently related to PTSD improvement.
Conclusions
HIV care settings can become an important venue for the identification and treatment of psychiatric problems affecting women with HIV in postconflict and developing countries. Providing opportunities for women with PTSD symptoms to share their history of trauma to trained counselors and addressing depression, poverty, and ongoing violence may contribute to reducing symptoms.

2.  Prevalence of Kidney Disease in HIV-Infected and Uninfected Rwandan Women 
PLoS ONE  2011;6(3):e18352.
Background
In the United States, HIV-related kidney disease disproportionately affects individuals of African descent; however, there are few estimates of kidney disease prevalence in Africa. We evaluated the prevalence of kidney disease among HIV-infected and uninfected Rwandan women.
Methods
The Rwandan Women's Interassociation Study and Assessment prospectively enrolled 936 women. Associations with estimated glomerular filtration rate (eGFR)<60 mL/min/1.73 m2 and proteinuria were assessed in separate logistic regression models.
Results
Among 891 non-pregnant women with available data, 2.4% had an eGFR<60 mL/min/1.73 m2 (calculated by the Modification of Diet in Renal Disease equation, MDRD eGFR) and 8.7% had proteinuria ≥1+. The prevalence of decreased eGFR varied markedly depending on the estimating method used, with the highest prevalence by Cockcroft-Gault. Regardless of the method used to estimate GFR, the proportion with decreased eGFR or proteinuria did not differ significantly between HIV-infected and -uninfected women in unadjusted analysis. After adjusting for age and blood pressure, HIV infection was associated with significantly higher odds of decreased MDRD eGFR but not proteinuria.
Conclusion
In a well-characterized cohort of Rwandan women, HIV infection was associated with decreased MDRD eGFR. The prevalence of decreased eGFR among HIV-infected women in our study was lower than that previously reported in African-Americans and in other Central and East African HIV populations, although there was substantial variability depending on the equation used to estimate GFR. Future studies are needed to optimize GFR estimates and to determine the impact of antiretroviral therapy on kidney disease in this population.

3.  Prevalence and Predictors of Posttraumatic Stress Disorder and Depression in HIV-Infected and At-Risk Rwandan Women 
Journal of Women's Health  2009;18(11):1783-1791.
Abstract
Objective
During the 1994 Rwandan genocide, rape was used as a weapon of war to transmit HIV. This study measures trauma experiences of Rwandan women and identifies predictors associated with posttraumatic stress disorder (PTSD) and depressive symptoms.
Methods
The Rwandan Women's Interassociation Study and Assessment (RWISA) is a prospective observational cohort study designed to assess effectiveness and toxicity of antiretroviral therapy in HIV-infected Rwandan women. In 2005, a Rwandan-adapted Harvard Trauma Questionnaire (HTQ) and the Center for Epidemiologic Studies Depression Scale (CES-D) were used to assess genocide trauma events and prevalence of PTSD (HTQ mean >2) and depressive symptoms (CES-D ≥ 16) for 850 women (658 HIV-positive and 192 HIV-negative).
Results
PTSD was common in HIV-positive (58%) and HIV-negative women (66%) (p = 0.05). Women with HIV had a higher prevalence of depressive symptoms than HIV-negative women (81% vs. 65%, p < 0.0001). Independent predictors for increased PTSD were experiencing more genocide-related trauma events and having more depressive symptoms. Independent predictors for increased depressive symptoms were making <$18 a month, HIV infection (and, among HIV-positive women, having lower CD4 cell counts), a history of genocidal rape, and having more PTSD symptoms.
Conclusions
The prevalence of PTSD and depressive symptoms is high in women in the RWISA cohort. Four of five HIV-infected women had depressive symptoms, with highest rates among women with CD4 cell counts <200. In addition to treatment with antiretroviral therapy, economic empowerment and identification and treatment of depression and PTSD may reduce morbidity and mortality among women in postconflict countries.

4.  Arterial Wave Reflection in HIV-Infected and HIV-Uninfected Rwandan Women 
Abstract
To assess differences in arterial wave reflection, a marker of atherosclerosis, in HIV-positive and HIV-negative Rwandan women, applanation tonometry was performed on 276 HIV+ and 67 HIV− participants. Radial artery pressure waveforms were recorded and central aortic waveforms were derived by validated transfer function. Central augmentation index (C-AI), central pulse pressure (C-PP), and peripheral augmentation index (P-AI) were measured. HIV+ participants were younger and had lower diastolic blood pressure (BP) and 41% of the HIV+ women were taking antiretroviral therapy (ART). Mean C-AI and P-AI were significantly lower in HIV-infected than in uninfected participants (20.3 ± 12.0 vs. 25.5 ± 12.1, p = 0.002 and 74.6 ± 18.8 vs. 83.7 ± 20.0, p < 0.001). After age matching, C-AI, C-PP, and P-AI were similar among the groups. On multivariate analysis, age, heart rate, weight, and mean arterial pressure were independently associated with C-AI (R2 = 0.33, p < 0.0001). Among HIV-infected women, current CD4 count did not correlate with C-AI (Rho = −0.01, p = 0.84), C-PP (Rho = 0.09, p = 0.16), or P-AI (Rho = −0.01, p = 0.83). In conclusion, HIV infection was not associated with increased arterial wave reflection in women with little exposure to antiretroviral therapy and without CV risk factors. Whether long-term ART increases measures of arterial stiffness remains unknown.
