Impact of point-of-care birth test-and-treat on clinical outcomes among infants with HIV: A cluster randomized trial in Mozambique and Tanzania.

Background: We assessed the impact of point-of-care (PoC) test-and-treat at birth on clinical outcomes and viral suppression among HIV-positive infants in Mozambique and Tanzania.

Methods: This cluster-randomized trial allocated health facilities to intervention, providing PoC-testing and antiretroviral treatment (ART) at birth and week 4-8, or control, starting these at week 4-8. The primary outcome was proportions of clinical events (mortality, morbidity, retention, virological failure, toxicity) among HIV-positive infants at month-18.

Step towards elimination of Wuchereria bancrofti in Southwest Tanzania 10 years after mass drug administration with Albendazole and Ivermectin.

Background: Lymphatic filariasis is a mosquito transmitted parasitic infection in tropical regions. Annual mass treatment with ivermectin and albendazole is used for transmission control of Wuchereria bancrofti, the infective agent of lymphatic filariasis in many African countries, including Tanzania.

Methodology: In a general population study in Southwest Tanzania, individuals were tested for circulating filarial antigen, an indicator of W.

HPV Type Distribution in HIV Positive and Negative Women With or Without Cervical Dysplasia or Cancer in East Africa.

Background: Women living with HIV in sub-Saharan Africa are at increased risk to develop cervical cancer (CC), which is caused by persistent infection with 13 oncogenic human papilloma viruses (HR-HPVs). It is important to accurately identify and target HIV-positive women at highest risk to develop CC for early therapeutic intervention.

Methods: A total of 2,134 HIV+ and HIV- women from South-West Tanzania were prospectively screened for cervical cancer and precancerous lesions.

Depletion and activation of mucosal CD4 T cells in HIV infected women with HPV-associated lesions of the cervix uteri.

Background: The burden of HPV-associated premalignant and malignant cervical lesions remains high in HIV+ women even under ART treatment. In order to identify possible underlying pathophysiologic mechanisms, we studied activation and HIV co-receptor expression in cervical T-cell populations in relation to HIV, HPV and cervical lesion status.

Methods: Cervical cytobrush (n = 468: 253 HIV- and 215 HIV+; 71% on ART) and blood (in a subset of 39 women) was collected from women in Mbeya, Tanzania.
