The objective of the study was to assess the effectiveness of group counseling, using a problem-solving therapy approach, on reducing depressive symptoms and increasing prenatal disclosure rates of HIV status among HIV-positive pregnant women living in Dar es Salaam, Tanzania. A randomized controlled trial was performed comparing a six-week structured nurse-midwife facilitated psychosocial support group with the standard of care. Sixty percent of women in the intervention group were depressed post-intervention, versus 73% in the control group [Relative Risk (RR) = 0.82, 95% confidence interval (CI): 0.67-1.01, p=0.066]. HIV disclosure rates did not differ across the two study arms. However, among those women who disclosed, there was a significantly higher level of overall personal satisfaction with the response to disclosure from family and friends among women in the treatment (88%) compared to the control group (62%; p=0.004). The results indicate reductions in the level of depressive symptoms comparable with major depressive disorder (MDD) for HIV-positive pregnant women participating in a group counseling intervention. Although the psychosocial group counseling did not significantly increase disclosure rates, an improvement in the level of personal satisfaction resulting from disclosure was associated with the intervention. This suggests that the counseling sessions have likely reduced the burden of depression and helped clients better manage partner reactions to disclosure. Public agencies and non-governmental organizations working in Tanzania and similar settings should consider offering structured psychosocial support groups to HIV-positive pregnant women to prevent poor mental health outcomes, promote early childhood development, and potentially impact HIV-related disease outcomes in the long term.

BackgroundCD4+ T-lymphocyte count (CD4 count) is a standard method used to monitor HIV-infected patients during anti-retroviral therapy (ART). The World Health Organization (WHO) has pointed out or recommended that a handheld, point-of-care, reliable, and affordable CD4 count platform is urgently needed in resource-scarce settings.MethodsHIV-infected patient blood samples were tested at the point-of-care using a portable and label-free microchip CD4 count platform that we have developed. A total of 130 HIV-infected patient samples were collected that included 16 de-identified left over blood samples from Brigham and Women's Hospital (BWH), and 114 left over samples from Muhimbili University of Health and Allied Sciences (MUHAS) enrolled in the HIV and AIDS care and treatment centers in the City of Dar es Salaam, Tanzania. The two data groups from BWH and MUHAS were analyzed and compared to the commonly accepted CD4 count reference method (FACSCalibur system).ResultsThe portable, battery operated and microscope-free microchip platform developed in our laboratory (BWH) showed significant correlation in CD4 counts compared with FACSCalibur system both at BWH (r = 0.94, p<0.01) and MUHAS (r = 0.49, p<0.01), which was supported by the Bland-Altman methods comparison analysis. The device rapidly produced CD4 count within 10 minutes using an in-house developed automated cell counting program.ConclusionsWe obtained CD4 counts of HIV-infected patients using a portable platform which is an inexpensive (<$1 material cost) and disposable microchip that uses whole blood sample (<10 µl) without any pre-processing. The system operates without the need for antibody-based fluorescent labeling and expensive fluorescent illumination and microscope setup. This portable CD4 count platform displays agreement with the FACSCalibur results and has the potential to expand access to HIV and AIDS monitoring using fingerprick volume of whole blood and helping people who suffer from HIV and AIDS in resource-limited settings.

To understand patient and clinician attitudes toward Streptococcus pharyngitis and rheumatic heart disease prevention in Tanzania, data from 3 sources were obtained: a survey of 119 clinicians, outpatient rapid test screening, and interviews with 17 rheumatic heart disease patients. Patients do not seek care for sore throat. Clinicians stated that identifying and treating Streptococcus pharyngitis is not prioritized.
