Priscilla Tsondai recently completed her Master’s in Public Health (Epidemiology) degree at the University of Cape Town. Her thesis was titled: “HIV viral load monitoring in HIV-infected pregnant women established on antiretroviral therapy in Cape Town, South Africa”. The literature review discussed the role of HIV viral load and antiretroviral therapy (ART) on vertical transmission of HIV and compared the existing ART monitoring strategies and management of viremia in resource-limited settings. She described public sector HIV viral load testing patterns (frequency and timing) and HIV viral load levels for pregnant women conceiving on ART, before and during pregnancy. In addition, the analysis assessed factors associated with having a HIV viral load (VL) test performed and being viremic during pregnancy. Defining viremia as a VL >1000 copies/mL, the analysis concluded that 80% of women had VL tests done during pregnancy, and of these approximately 88% had VL <1000 copies/mL For women with a raised VL during pregnancy, under 60% had repeat VL tests performed before delivery; and of those that did, over half were still viremic on the second test.

Priscilla is currently working as a Research Officer and has just begun her PhD at the University of Cape Town. Her PhD will focus on the models of care and the models of transition to adult HIV services for HIV-infected adolescents within Southern Africa.

Eliane is a medical doctor and has recently completed her MSc in Epidemiology (2015) at the London School of Hygiene and Tropical Medicine by distance learning. Her research focus is HIV-related cancer and oncogenic viruses and her MSc thesis examined the incidence rate of invasive cervical cancer (ICC) in a South African cohort of HIV-positive women. In a meta-analysis, she examined the association between HIV and human herpesvirus 8 (HHV-8), the infectious cause of Kaposi sarcoma (KS). This meta-analysis showed that HIV-positive persons were more likely to be seropositive for HHV-8 than HIV-negative persons. Another research project focused on the incidence rate of KS and associated risk factors in HIV-positive children and adults participating in IeDEA-SA. She is also working on multiregional IeDEA projects to estimate and compare ICC and KS incidence rates in HIV-positive persons across different continents.

Victoria completed her MPH (Epidemiology) degree in 2016 at the University of Cape Town. Her thesis was titled “Prevalence and determinants of unplanned pregnancy in HIV-positive and HIV-negative pregnant women in Cape Town, South Africa: a cross-sectional study” She described the importance of preventing unplanned pregnancies among HIV-positive women as one of the crucial tools for the prevention of mother-to-child transmission of HIV (PMTCT) in high burden, resource-limited settings such as South Africa. The study presented key differences between HIV-positive and HIV-negative women regarding pregnancy intentions and family planning practices. Younger age (<24 years old), increasing parity and contraceptive use in the year prior to conception were associated with an increased probability of an unplanned pregnancy. The manuscript was published in BMJ Open (Iyun et al. 2018).

Victoria is currently working on her PhD project at the University of Cape Town. Her PhD is focused on understanding the effect of expanded early infant diagnosis (EID) and early infant antiretroviral therapy (EIART) guidelines and practices, on patient and program-level outcomes among HIV-infected infants and young children in resource-limited settings.

Mmamapudi completed her MPH in 2016, her thesis sought to understand the epidemiology of
diabetes in a high tuberculosis and HIV context Khayelitsha, South Africa. She was also involved in a
study that determined the association between TB and diabetes. (odds ratio 2.4; 95% confidence
interval 1.3–4.3) in a study population with high HIV prevalence (64%) (1). Building on her MPH work, she is currently working on her PhD project that seeks to understand the effect of diabetes, HIV and household overcrowded living conditions on the South African TB epidemic. She will develop an individual-based model to represent TB dynamics in South Africa. The model will be used to: a) understand and explain the observed gender and age differences in TB; b) assess how effective current TB control interventions have been in reducing TB incidence in South Africa up to the current time c) determine the population attributable burden of tuberculosis due to HIV, diabetes, and household overcrowded living conditions; and d) evaluate the potential impact of current TB control interventions that target to reduce HIV, diabetes and household overcrowding in
addition to current TB control interventions.

After completing a Master’s degree in Sociology at Goldsmiths, University of London, Andreas joined the ISPM in 2012, where he completed his PhD in Epidemiology. His PhD project evaluated the effectiveness of Malawi’s “Option B+”. Specifically, the project aims were to identify challenges to program success, and then to plan and carry-out appropriate interventions.
In 2011, the Malawian MoH developed a pragmatic public health approach to improve the low antiretroviral coverage among pregnant women in Malawi and implemented the “Option B+” protocol. Option B+ provides universal lifelong ART for all HIV-infected pregnant and breastfeeding women, regardless of CD4 cell count and/or WHO clinical stage. Following the national implementation of Option B+ the antiretroviral coverage among pregnant women in Malawi increased from 49% in 2011 to 85% in 2014 and numerous other countries have adopted the Option B+ policy.
In November 2016, Andreas was awarded the 2016 annual SSPH+ Award for the best published PhD article resulting from his PhD: “Retention in care during the first 3 years of antiretroviral therapy for women in Malawi’s option B+ programme: an observational cohort study”,

Julie Jesson has joined IeDEA-SA in 2017 as a post-doc fellow to conduct a multiregional analysis on growth among HIV-infected adolescents. She previously completed her PhD with the University of Bordeaux, France, on ‘malnutrition and pediatric HIV infection in West Africa’, in collaboration with IeDEA pWADA (pediatric West African Databases). The main results were that prevalence of malnutrition was high among HIV-infected children, but growth improved after ART initiation in the first 24 months of ART, with the better weight and height gains for those early initiated on ART (before two years of age). However, those who remained malnourished while on long-term ART could be at high risk of death. Also, Ready-to-Use Therapeutic Food was efficient to treat weight deficiency among HIV-infected children. Height deficiency was difficult to reverse and even impaired the recovery for weight deficiency. A greater documentation and awareness of nutritional aspects of pediatric HIV care in resource-limited settings are needed and adapted nutritional interventions focused on HIV-infected children have to be developed. During her post-doc, her focus is now on HIV-adolescents, who represents a specific population in terms of HIV care as well as nutritional needs.
