Survey of children accessing HIV services in a high prevalence setting: time for adolescents to count?

OBJECTIVE: To establish the proportion of adolescents among children infected with human immunodeficiency virus (HIV) in Zimbabwe who receive HIV care and support, and what clinic staff perceives to be the main problems faced by HIV-infected children and adolescents. METHODS: In July 2008, we sent a questionnaire to all 131 facilities providing HIV care in Zimbabwe. In it we requested an age breakdown of the children (aged 0-19 years) registered for care and asked what were the two major problems faced by younger children (0-5 years) and adolescents (10-19 years). FINDINGS: Nationally, 115 (88%) facilities responded. In 98 (75%) that provided complete data, 196 032 patients were registered and 24 958 (13%) of them were children. Of children under HIV care, 33% were aged 0-4 years; 25%, 5-9 years; 25%, 10-14 years; and 17%, 15-19 years. Staff highlighted differences in the problems most commonly faced by younger children and adolescents. For younger children, such problems were malnutrition and lack of appropriate drugs (cited by 46% and 40% of clinics, respectively); for adolescents they concerned psychosocial issues and poor drug adherence (cited by 56% and 36%, respectively). CONCLUSION: Interventions for the large cohort of adolescents who are receiving HIV care in Zimbabwe need to target the psychosocial concerns and poor drug adherence reported by staff as being the main concerns in this age group

Burden of HIV among primary school children and feasibility of primary school-linked HIV testing in Harare, Zimbabwe: a mixed methods study.

Population-based surveys in Southern Africa suggest a substantial burden of undiagnosed HIV-infected long-term survivors of mother-to-child transmission. We conducted an HIV prevalence survey of primary school pupils in Harare, Zimbabwe, and evaluated school-linked HIV counselling and testing (HCT) for pupils, their families and schoolteachers. Population-weighted cluster sampling was used to select six primary schools. Randomly selected class-grade pupils underwent anonymous HIV testing, with concurrent school-linked family HCT offered during the survey. Focus group discussions and interviews were conducted with pupils, parents/guardians, counsellors, and schoolteachers. About 4386 (73%) pupils provided specimens for anonymous HIV testing. Median age was 9 years (IQR 8-11), and 54% were female. HIV prevalence was 2.7% (95% CI: 2.2-3.1) with no difference by gender. HIV infection was significantly associated with orphanhood, stunting, wasting, and being one or more class grades behind in school due to illness (p<0.001). After adjusting for covariates, orphanhood and stunting remained significantly associated with being HIV positive (p<0.001). Uptake of diagnostic HIV testing by pupils was low with only 47/4386 (1%) pupils undergoing HCT. The HIV prevalence among children under 15 years who underwent HIV testing was 6.8%. The main barrier to HIV testing was parents' fear of their children experiencing stigma and of unmasking their own HIV status should the child test HIV positive. Most guardians believed that a child's HIV-positive result should not be disclosed and the child could take HIV treatment without knowing the reason. Increased recognition of the high burden of undiagnosed HIV infection in children is needed. Despite awareness of the benefits of HIV testing, HIV-related stigma still dominates parents/guardians' psychological landscape. There is need for comprehensive information and support for families to engage with HIV testing services

Positive attitudes to pediatric HIV testing: findings from a nationally representative survey from Zimbabwe.

Early HIV testing and diagnosis are paramount for increasing treatment initiation among children, necessary for their survival and improved health. However, uptake of pediatric HIV testing is low in high-prevalence areas. We present data on attitudes towards pediatric testing from a nationally representative survey in Zimbabwe

Malnutrition enteropathy in Zambian and Zimbabwean children with severe acute malnutrition: A multi-arm randomized phase II trial.

Malnutrition underlies almost half of all child deaths globally. Severe Acute Malnutrition (SAM) carries unacceptable mortality, particularly if accompanied by infection or medical complications, including enteropathy. We evaluated four interventions for malnutrition enteropathy in a multi-centre phase II multi-arm trial in Zambia and Zimbabwe and completed in 2021. The purpose of this trial was to identify therapies which could be taken forward into phase III trials. Children of either sex were eligible for inclusion if aged 6-59 months and hospitalised with SAM (using WHO definitions: WLZ <-3, and/or MUAC <11.5 cm, and/or bilateral pedal oedema), with written, informed consent from the primary caregiver. We randomised 125 children hospitalised with complicated SAM to 14 days treatment with (i) bovine colostrum (n = 25), (ii) N-acetyl glucosamine (n = 24), (iii) subcutaneous teduglutide (n = 26), (iv) budesonide (n = 25) or (v) standard care only (n = 25). The primary endpoint was a composite of faecal biomarkers (myeloperoxidase, neopterin, α1-antitrypsin). Laboratory assessments, but not treatments, were blinded. Per-protocol analysis used ANCOVA, adjusted for baseline biomarker value, sex, oedema, HIV status, diarrhoea, weight-for-length Z-score, and study site, with pre-specified significance of P < 0.10. Of 143 children screened, 125 were randomised. Teduglutide reduced the primary endpoint of biomarkers of mucosal damage (effect size -0.89 (90% CI: -1.69,-0.10) P = 0.07), while colostrum (-0.58 (-1.4, 0.23) P = 0.24), N-acetyl glucosamine (-0.20 (-1.01, 0.60) P = 0.67), and budesonide (-0.50 (-1.33, 0.33) P = 0.32) had no significant effect. All interventions proved safe. This work suggests that treatment of enteropathy may be beneficial in children with complicated malnutrition. The trial was registered at ClinicalTrials.gov with the identifier NCT03716115

Using Vignettes in Qualitative Research to Explore Barriers and Facilitating Factors to the Uptake of Prevention of Mother-to-Child Transmission Services in Rural Tanzania: A Critical Analysis.

Vignettes are short stories about a hypothetical person, traditionally used within research (quantitative or qualitative) on sensitive topics in the developed world. Studies using vignettes in the developing world are emerging, but with no critical examination of their usefulness in such settings. We describe the development and application of vignettes to a qualitative investigation of barriers to uptake of prevention of mother-to-child transmission (PMTCT) HIV services in rural Tanzania in 2012, and critique the successes and challenges of using the technique in this setting. Participatory Learning and Action (PLA) group activities (3 male; 3 female groups from Kisesa, north-west Tanzania) were used to develop a vignette representing realistic experiences of an HIV-infected pregnant woman in the community. The vignette was discussed during in-depth interviews with 16 HIV-positive women, 3 partners/relatives, and 5 HIV-negative women who had given birth recently. A critical analysis was applied to assess the development, implementation and usefulness of the vignette. The majority of in-depth interviewees understood the concept of the vignette and felt the story was realistic, although the story or questions needed repeating in some cases. In-depth interviewers generally applied the vignette as intended, though occasionally were unsure whether to steer the conversation back to the vignette character when participants segued into personal experiences. Interviewees were occasionally confused by questions and responded with what the character should do rather than would do; also confusing fieldworkers and presenting difficulties for researchers in interpretation. Use of the vignette achieved the main objectives, putting most participants at ease and generating data on barriers to PMTCT service uptake. Participants' responses to the vignette often reflected their own experience (revealed later in the interviews). Participatory group research is an effective method for developing vignettes. A vignette was incorporated into qualitative interview discussion guides and used successfully in rural Africa to draw out barriers to PMTCT service use; vignettes may also be valuable in HIV, health service use and drug adherence research in this setting. Application of this technique can prove challenging for fieldworkers, so thorough training should be provided prior to its use

Profiling the mental health of diabetic patients: a cross-sectional survey of Zimbabwean patients

Objective The burden of diabetes mellitus has exponentially increased in low resource settings. Patients with diabetes are more likely to exhibit poor mental health which negatively affects treatment outcomes. However, patients with high levels of social support (SS) are likely to report optimal mental health. We sought to determine how SS affects the report of psychiatric morbidity and health-related quality of life (HRQoL) in 108 diabetic patients in Harare, Zimbabwe. Results The average age of participants was 54.1 (SD 18.6) years. Most of the participants were; females (69.4%), married (51.9%), and were of low level of income (43.5%). 37.1% of the participants exhibited signs of psychiatric morbidity [mean Shona Symptoms Questionnaire score—6.7 (SD 3.2)]. Further, patients also reported lower HRQoL [mean EQ-5D-VAS score—64.1 (SD 15.3)] and high levels of SS [mean Multidimensional Scale of Perceived Social Support score—43.7 (SD 11.5)]. Patients who received greater amount of SS had optimal mental health. Being female, unmarried, lower education attainment, having more comorbid conditions, being diagnosed with type 2 diabetes and having been diagnosed of diabetes for a longer duration were associated with poorer mental health. It is important to develop context-specific interventions to improve diabetic patients’ mental health

Association of genital shedding of herpes simplex virus type 2 and HIV-1 among sex workers in rural Zimbabwe.

INTRODUCTION: Herpes simplex virus type 2 (HSV-2) facilitates sexual acquisition of HIV-1 but data on transmission are less clear. In this study the interaction between genital shedding of HIV-1 and HSV-2 was explored among Zimbabwean sex workers. METHODS: Women (n = 214) were interviewed about genital symptoms. Blood samples were analysed for HIV-1 and HSV-2 antibodies, HIV-1 plasma viral load (PVL) and CD4 lymphocyte count and genital swabs for detection of HIV-1 and HSV-2 genital shedding, Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis, and a cervico-vaginal lavage (CVL) for quantitative measurement of HIV-1 shedding. Shedding analyses were undertaken on women co-infected with HSV-2 and HIV-1. RESULTS: A total of 124 women were co-infected with HIV-1 and HSV-2; 58 were infected with HSV-2 alone. Most HIV-1-infected women were co-infected with HSV-2 (95.4%). Genital HIV-1 shedding was detected in 84.3% of co-infected women and was associated with low CD4 cell count and high PVL but not with reported symptoms of genital herpes or genital shedding of HSV-2. There was no difference in HIV-1 shedding among women shedding HSV-2 (79.3%) and women not shedding HSV-2 (83.2%) (P = 0.64). The adjusted odds ratio for HIV-1 shedding between HSV-2 shedders and non-shedders was 0.8 [95% confidence interval (CI), 0.2-3.3]. HIV-1 PVL(log10) and CVL viral load(log10) were correlated (r = 0.38; 95%CI, 0.2-0.5). After adjusting for PVL, genital symptoms and age, HSV-2 shedding had no effect on CVL viral load (P = 0.13). CONCLUSION: Rate and quantity of HIV-1 genital shedding do not appear to be altered by presence of HSV-2 genital shedding

Associations between adolescent experiences of violence in Malawi and gender-based attitudes, internalizing, and externalizing behaviors

Little is known about adolescent exposure to and factors associated with violence in Malawi. The aim of this research was to describe the prevalence of exposure to violence among adolescents in Malawi, and test the hypotheses that such exposures are associated with genderbased violent attitudes, and with internalizing and externalizing problems. In 2014, 561 primary school pupils were interviewed (50% girls), and logistic regression analysis was performed on gender-stratified data, adjusting for sociodemographic differences. Both girls and boys had witnessed domestic violence (28.5% and 29.6%), experienced emotional abuse at home (23.1% and 22.9%), physical abuse at home (28.1% and 30.4%), physical abuse at school (42.4% and 36.4%), and been bullied (33.8% and 39.6%). Among girls, internalized violent attitudes towards women were associated with emotional abuse at home (OR 2.1) and physical abuse at school (OR 1.7). Condoning rape was associated with physical abuse at school (OR 1.9). Bullying perpetration was associated with emotional abuse at home (OR 4.5). Depression was associated with emotional abuse at home (OR 3.8) and physical abuse at school (OR 2.4). Among boys, violent attitudes towards women and condoning rape were not associated with violence exposure. Bullying perpetration was associated with having been a victim of bullying (OR 2.9) and physical abuse at school (OR 2.7). Depression was associated with emotional abuse at home (OR 2.9), domestic violence (OR 2.4) and physical abuse at school (OR 2.5). These findings can inform programs designed to reduce violence victimization among Malawian girls, both in homes and schools
