RESUMEN

BACKGROUND: Preterm birth is a leading cause of death in children under the age of five. The risk of preterm birth is increased by maternal HIV infection as well as by certain antiretroviral regimens, leading to a disproportionate burden on low- and medium-income settings where HIV is most prevalent. Despite decades of research, the mechanisms underlying spontaneous preterm birth, particularly in resource limited areas with high HIV infection rates, are still poorly understood and accurate prediction and therapeutic intervention remain elusive. OBJECTIVES: Metabolomics was utilized to identify profiles of preterm birth among pregnant women living with HIV on two different antiretroviral therapy (ART) regimens. METHODS: This pilot study comprised 100 mother-infant dyads prior to antiretroviral initiation, on zidovudine monotherapy or on protease inhibitor-based antiretroviral therapy. Pregnancies that resulted in preterm births were matched 1:1 with controls by gestational age at time of sample collection. Maternal plasma and blood spots at 23-35 weeks gestation and infant dried blood spots at birth, were assayed using an untargeted metabolomics method. Linear regression and random forests classification models were used to identify shared and treatment-specific markers of preterm birth. RESULTS: Classification models for preterm birth achieved accuracies of 95.5%, 95.7%, and 80.7% in the untreated, zidovudine monotherapy, and protease inhibitor-based treatment groups, respectively. Urate, methionine sulfone, cortisone, and 17α-hydroxypregnanolone glucuronide were identified as shared markers of preterm birth. Other compounds including hippurate and N-acetyl-1-methylhistidine were found to be significantly altered in a treatment-specific context. CONCLUSION: This study identified previously known as well as novel metabolomic features of preterm birth in pregnant women living with HIV. Validation of these models in a larger, independent cohort is necessary to ascertain whether they can be utilized to predict preterm birth during a stage of gestation that allows for therapeutic intervention or more effective resource allocation.

RESUMEN

ABSTRACT: We conducted an observational study of lymphogranuloma venereum (LGV) biovar Chlamydia trachomatis infection in HIV-infected women in South Africa. The LGV biovar was detected in vaginal specimens of 17 (20%) of 85 women with C. trachomatis infection; 29% were symptomatic. All cases were negative for the LGV biovar after single-dose azithromycin.

RESUMEN

Availability of HIV self-testing may increase HIV testing frequency among men who have sex with men (MSM). It is unclear, however, if self-testing may impact HIV-related sexual behaviors among MSM, including HIV status disclosure and condom use. We conducted a mixed methods analysis of changes in HIV-related behaviors after HIV self-testing introduction, using data from 110 MSM participating in a feasibility and acceptability study of HIV self-testing in Mpumalanga Province, South Africa. We found increased HIV status disclosure from study participants to sexual partners after HIV self-testing introduction, from 61.8% at baseline to 75.5% at 6-month follow-up (p = 0.04), but decreased condom use with female partners (p = 0.03). Qualitative interviews reveal that some participants used test results to inform condom use. Distribution of self-testing kits can improve mutual disclosure, but should be accompanied by information stressing that the tests may not detect early HIV infections or other sexually transmitted infections.

RESUMEN

Provision of high-quality care and ensuring retention of children on antiretroviral therapy (ART) are essential to reduce human immunodeficiency virus (HIV)-associated morbidity and mortality. Virological non-suppression (≥1000 viral copies/ml) is an indication of suboptimal HIV care and support. This retrospective cohort study included ART-naïve children who initiated first-line ART between July 2015 and August 2017 in Johannesburg and rural Mopani district. Of 2739 children started on ART, 29.5% (807/2739) were lost to care at the point of analysis in August 2018. Among retained children, overall virological non-suppression was 30.2% (469/1554). Virological non-suppression was associated with higher loss to care 30.3% (229/755) compared with suppressed children (9.7%, 136/1399, P < 0.001). Receiving treatment in Mopani was associated with virological non-suppression in children under 5 years (adjusted odds ratio (aOR) 1.7 (95% confidence interval (CI) 1.1-2.4), 5-9 years (aOR 1.8 (1.1-3.0)) and 10-14 years (aOR 1.9 (1.2-2.8)). Virological non-suppression was associated with lower CD4 count in children 5-9 years (aOR 2.1 (1.1-4.1)) and 10-14 years (aOR 2.1 (1.2-3.8)). Additional factors included a shorter time on ART (<5 years aOR 1.8-3.7 (1.3-8.2)), and male gender (5-9 years, aOR1.5 (1.01-2.3)), and receiving cotrimoxazole prophylaxis (10-14 years aOR 2.0 (1.2-3.6)). In conclusion, virological non-suppression is a factor of subsequent programme loss in both regions, and factors affecting the quality of care need to be addressed to achieve the third UNAIDS 90 in paediatric HIV.

RESUMEN

BACKGROUND: The burden of sexually transmitted infections (STIs) in areas of sub-Saharan Africa with poor access to health care services is not well documented. In remote areas of South Africa, we investigated the prevalence of STIs and approaches to providing STI services through a mobile clinic. METHODS: We recruited 251 adult women visiting a mobile clinic that normally provides general health education and screening services, but not STI care. Clinical and sexual history was obtained and vaginal specimens were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Mycoplasma genitalium infection and for Candida albicans and bacterial vaginosis. RESULTS: Laboratory test was positive for 133 (53%) of 251 women for at least 1 STI: C. trachomatis was observed in 52 (21%) women, N. gonorrhoeae in 39 (16%) women, T. vaginalis in 81 (32%) women and M. genitalium in 21 (8%) women. Eighty-one (32%) women met the criteria for vaginal discharge syndrome, of which 58% (47/81) would have been treated accurately. Among asymptomatic women 84 (49%) of 170 were diagnosed with an STI but untreated under the syndromic approach. We could not identify factors associated with asymptomatic STI infection. CONCLUSIONS: There is a high unmet need for STI care in rural South African settings with poor access to health care services. Provision of STI services in a mobile clinic using the syndromic management approach provides a useful approach, but would have to be enhanced by targeted diagnostics to successfully address the burden of infection.

RESUMEN

We observed a high rate of incident sexually transmitted diseases within 55 days (median) of follow-up (78% retention) among symptomatic men who have sex with men (n = 78) in South Africa (188 per 100 person-years; 95% confidence interval, 1.2-2.7); 16 newly acquired and 10 with persistent positivity. This highlights the need to strengthen prevention efforts, whereas introduction of diagnostics is urgently warranted.

RESUMEN

OBJECTIVES: To determine the unmet need for care and barriers for consulting sexually transmitted infection (STI) services at six primary healthcare (PHC) facilities in rural South Africa. METHODS: Cross-sectional study using three community-based strategies to mobilise adult individuals with STI-associated symptoms to access care. Participants were mobilised through clinic posters and referral by community healthcare workers (CHWs) and traditional leaders after training. Men with male urethritis syndrome and women with vaginal discharge syndrome were mobilised to visit participating PHC facilities on two designated days when an expert team visited the facility. Questionnaires were completed and HIV rapid tests offered. The minimal unmet need for care of individuals with STI-associated symptoms was calculated by dividing the number of cases over the adult catchment population of each PHC facility. RESULTS: We successfully mobilised 177 symptomatic individuals: 134 (76%) women and 43 (24%) men. The estimated minimal unmet need for STI care was 1:364 (95% CI 1:350-1:380) individuals in this region; the rate was higher in village than township facilities, and among women. Mobilisation through clinic posters (57%) and by CHWs (23%) was most successful. Three-quarters of individuals (132/177) reported symptoms that had been present for >30 days; 49% (87/177) had symptoms >6 months. In addition, we identified 14 individuals with untreated HIV infection amounting to a 7% HIV testing yield. Lack of awareness of symptoms (34%), and disappointment in care due to persistent (23%) or recurrent (15%) symptoms after previous treatment, or disappointment with health services in general during previous visit(s) for any reason (10%) was the most common reasons for not consulting health care. CONCLUSIONS: We demonstrate a high unmet need for care of individuals with STI-associated symptoms in rural South Africa that requires urgent attention. A multidisciplinary approach that creates service demand through community awareness and information provision by healthcare workers combined with strengthening the quality of STI services is required to improve reproductive health and prevent complications of untreated STIs in this population.


OBJECTIFS: Déterminer les besoins non satisfaits en matière de soins et les obstacles à la consultation des services pour IST dans six établissements de soins de santé primaires (SSP) en milieu rural en Afrique du Sud. MÉTHODES: Etude transversale utilisant trois stratégies communautaires pour mobiliser les individus adultes présentant des symptômes associés aux IST afin qu'ils puissent accéder aux soins. Les participants ont été mobilisés à travers des affiches dans les cliniques et sur recommandation des agents de santé communautaires (ASC) et des chefs traditionnels après une formation. Les hommes atteints du syndrome d'urétrite masculin et les femmes atteintes du syndrome de pertes vaginales ont été mobilisés à visiter les établissements de SSP participants, au cours de deux jours choisis lorsqu'une équipe d'experts était présente dans l'établissement. Des questionnaires ont été remplis et des tests de dépistage rapides du VIH ont été proposés. Le besoin minimal non satisfait de soins pour les personnes présentant des symptômes associés aux IST a été calculé en divisant le nombre de cas par la population adulte de la zone de chaque établissement de SSP. RÉSULTATS: Nous avons réussi à mobiliser 177 personnes symptomatiques: 134 (76%) femmes et 43 (24%) hommes. Le besoin minimal non satisfait en matière de soins IST était de 1:364 (IC95%: 1:350 - 1:380) individus dans cette région; le taux était plus élevé dans les villages que dans les installations des bidonvilles et chez les femmes. La mobilisation par le biais d'affiches de cliniques (57%) et par les ASC (23%) a eu le plus de succès. Les trois quarts des personnes (132/177) ont signalé des symptômes présents depuis >30 jours; 49% (87/177) présentaient des symptômes > 6 mois. En outre, nous avons identifié 14 personnes présentant une infection par le VIH, non traitée, ce qui représente un rendement de dépistage du VIH de 7%. Le manque de prise de conscience des symptômes (34%) et la déception avec les soins en raison de symptômes persistants (23%) ou récurrents (15%) après un traitement précédent, ou la déception avec les services de santé en général lors de visites précédentes pour une raison quelconque (10 %) étaient les raisons les plus courantes de ne pas consulter les soins de santé. CONCLUSIONS: Dans les zones rurales d'Afrique du Sud, nous démontrons un besoin élevé de soins non satisfaits pour les personnes présentant des symptômes associés aux IST et nécessitant une attention urgente. Une approche multidisciplinaire qui crée une demande de services par le biais de la sensibilisation de la communauté et de la fourniture d'informations par les agents de santé, associée au renforcement de la qualité des services IST, est nécessaire pour améliorer la santé reproductive et prévenir les complications des IST non traitées dans cette population.

RESUMEN

BACKGROUND: As the number of HIV-infected women initiating lifelong antiretroviral therapy (ART) during pregnancy increases globally, concerns have emerged regarding low levels of retention in HIV services and suboptimal adherence to ART during the postpartum period. We examined the impact of integrating postpartum ART for HIV+ mothers alongside infant follow-up within maternal and child health (MCH) services in Cape Town, South Africa. METHODS AND FINDINGS: We conducted a randomised trial among HIV+ postpartum women aged ≥18 years who initiated ART during pregnancy in the local antenatal care clinic and were breastfeeding when screened before 6 weeks postpartum. We compared an integrated postnatal service among mothers and their infants (the MCH-ART intervention) to the local standard of care (control)-immediate postnatal referral of HIV+ women on ART to general adult ART services and their infants to separate routine infant follow-up. Evaluation data were collected through medical records and trial measurement visits scheduled and located separately from healthcare services involved in either arm. The primary trial outcome was a composite endpoint of women's retention in ART care and viral suppression (VS) (viral load < 50 copies/ml) at 12 months postpartum; secondary outcomes included duration of any and exclusive breastfeeding, mother-to-child HIV transmission, and infant mortality. Between 5 June 2013 and 10 December 2014, a total of 471 mother-infant pairs were enrolled and randomised (mean age, 28.6 years; 18% nulliparous; 57% newly diagnosed with HIV in pregnancy; median duration of ART use at randomisation, 18 weeks). Among 411 women (87%) with primary endpoint data available, 77% of women (n = 155) randomised to the MCH-ART intervention achieved the primary composite outcome of retention in ART services with VS at 12 months postpartum, compared to 56% of women (n = 117) randomised to the control arm (absolute risk difference, 0.21; 95% CI: 0.12-0.30; p < 0.001). The findings for improved retention in care and VS among women in the MCH-ART intervention arm were consistent across subgroups of participants according to demographic and clinical characteristics. The median durations of any breastfeeding and exclusive breastfeeding were longer in women randomised to the intervention versus control arm (6.9 versus 3.0 months, p = 0.006, and 3.0 versus 1.4 months, p < 0.001, respectively). For the infants, overall HIV-free survival through 12 months of age was 97%: mother-to-child HIV transmission was 1.2% overall (n = 4 and n = 1 transmissions in the intervention and control arms, respectively), and infant mortality was 1.9% (n = 6 and n = 3 deaths in the intervention and control arms, respectively), and these outcomes were similar by trial arm. Interpretation of these findings should be qualified by the location of this study in a single urban area as well as the self-reported nature of breastfeeding outcomes. CONCLUSIONS: In this study, we found that integrating ART services into the MCH platform during the postnatal period was a simple and effective intervention, and this should be considered for improving maternal and child outcomes in the context of HIV. TRIAL REGISTRATION: ClinicalTrials.gov NCT01933477.

RESUMEN

BACKGROUND: Sexual behaviors in human immunodeficiency virus (HIV)-infected pregnant women in South Africa are not well understood. METHODS: Human immunodeficiency virus-infected pregnant women were recruited into a prospective cohort at first antenatal care visit. Sociodemographic information and self-collected vulvovaginal swab samples were collected from participants. Vulvovaginal swab samples were tested for Chlamydia trachomatis, Neisseria gonorrhoea, and Trichomonas vaginalis using GeneXpert. We investigated sexual behaviors, alcohol use, factors associated with condomless sex during pregnancy, and prevalent sexually transmitted infection (STI) among our cohort. We report descriptive, univariate and multivariable logistic regression results of sexual behaviors and alcohol use, factors associated with condomless sex at last sex, and having any STI during pregnancy adjusting for a priori confounders. RESULTS: We recruited and enrolled 430 HIV-infected pregnant women. Median age was 30 years; median gestational age was 20 weeks. Eighty-nine percent of women reported sex during pregnancy. At last sex, 68% reported condomless sex; 18% reported having more than 1 sex partner in the past 12 months. Adjusting for age, income and relationship status, condom use at last sex was associated with prior knowledge of HIV status (adjusted odds ratio [aOR], 2.46; 95% confidence interval [CI], 1.54-3.92) and being in a concordant HIV-positive (aOR, 3.17; 95% CI, 1.84-5.50), or serodiscordant relationship (aOR, 6.50; 95% CI, 3.59-11.80). The prevalence of any STI was 41% (95% CI, 36%-45%). Adjusting for mothers' age and employment, odds of having an STI increased if the woman reported alcohol use during pregnancy (aOR, 1.96; 95% CI, 1.06-3.64) or if the father of the child was a non-cohabiting or casual partner (aOR, 1.42; 95% CI, 0.97-2.03). CONCLUSIONS: Almost all HIV-infected pregnant women were sexually active during pregnancy and most women reported condomless sex at last sex. Condom use was associated with knowledge of serostatus and/or partner's serostatus before first antenatal care visit. Factors associated with having STIs included: alcohol use during pregnancy and father of child being a non-cohabiting partner.

RESUMEN

OBJECTIVE: To evaluate how electronic data management systems affect data use practices in antiretroviral therapy (ART) programs within local health districts, and individual health facilities. METHODS: We used a data quality audit to establish a baseline of the quality of data in the electronic register alongside in-depth interviews with health workers and managers, to understand perceptions of data quality, data use by facility staff and challenges affecting data use. RESULTS: The findings provide a four-level continuum of data use that can be applied to other settings and recommendations for optimising facility-level data use. CONCLUSION: By defining four levels of data use our findings suggest the potential to encourage a structured process of moving from passive data use, to more active and engaged data use, where data could be used to anticipate patient behaviour and link that behaviour to differentiated care plans.

RESUMEN

BACKGROUND: South Africa has implemented a community health programme delivered by community health workers (CHWs) to strengthen primary healthcare services. Provision of community Human Immunodeficiency Virus (HIV) services constitutes an important component of this programme. To support effectiveness, we assessed fidelity of HIV programme implementation by CHWs from the community's perspective in a rural South African setting. METHODS: A cross-sectional study was conducted targeting 900 randomly selected households in twelve wards of two sub-districts (Greater Giyani and Greater Letaba) of Mopani District (Limpopo Province, South Africa). Questionnaires were administered to the traditionally most appropriate adult member of the household. Included were questions related to the four standard components to measure implementation fidelity against local guidelines: coverage, frequency, duration and content of HIV programme implementation. RESULTS: Participants were enrolled at 534 households; in most other cases there was nobody or no adult member at home (n = 291). Reported coverage of 55% (141/253) and a frequency of 47% (66/140) were higher in Greater Giyani as compared to Greater Letaba (44%; 122/278 and 29%; 33/112, respectively, p = 0.007 for both comparisons). Coverage was not associated with the distance from the participant's household to the facility (p = 0.93). Duration of programme delivery was reported to be high, where all CHW visits (253/253; 100%) were conducted within the last 6 months and the content delivered was adequate (242/253; 96%). Individuals reporting a CHW visit were more likely to know their HIV status than those not visited (OR = 2.0; 95% CI 1.06-3.8; p = 0.032). Among those visited by the CHW discussion of HIV was associated with knowing the HIV status (OR = 2.2; 95% CI 1.02-4.6; p = 0.044); in particular for women (OR = 2.9; 95% CI 1.5-5.4; p = 0.001). CONCLUSIONS: This study demonstrates promising HIV programme implementation fidelity by CHWs in rural South Africa. Programme coverage and frequency should be improved whilst maintaining the good levels of duration and content. Resource investment, strengthening of operational structure, and research to identify other facilitators of programme implementation are warranted to improve programme effectiveness and impact.

RESUMEN

Background: The numbers of human immunodeficiency virus (HIV)-infected women initiating antiretroviral therapy (ART) in pregnancy are increasing rapidly with global policy changes. There are widespread concerns about ART adherence during pregnancy and postpartum but few data on viral suppression (VS) over time in these populations. Methods: We followed a cohort of 523 women in Cape Town, South Africa, initiating ART in pregnancy (once-daily tenofovir 300 mg, emtricitabine 200 mg, and efavirenz 600 mg) and achieving VS (<50 copies/mL). Participants provided specimens through 12 months postpartum for batched viral load (VL) testing separate from routine care. Analyses described the incidence of major (>1000 copies/mL) and minor (50-1000 copies/mL) viremic episodes (VEs) and factors associated with major VEs. Results: In the cohort (median age, 28 years; median pre-ART VL, 3.99 copies/mL; 3% previously defaulted ART; 24% with previous exposure to short-course antiretrovirals), the median time of follow-up from VS was 322 days. Overall, 70% maintained VS throughout follow-up, 8% experienced minor VEs only, and at least 1 major VE was documented in 22% of women. In women with VEs, peak viremia (median, 3.79 log10 copies/mL) was linearly related to pre-ART VL. The incidence of major VEs after initial VS was independently associated with younger age, ART initiation during the third trimester, previous defaulting on ART, and postpartum follow-up. Conclusions: Viremia appears to occur frequently, particularly postpartum, among HIV-infected women after initial VS in this setting. More intensive VL monitoring is warranted in this population; the immediate causes and long-term implications of VE require investigation.

RESUMEN

We detected Chlamydia trachomatis biovar L2 in vaginal swab specimens of 7 women with vaginal discharge in South Africa. Whole-genome sequencing directly from clinical specimens identified a closely related cluster of strains. The clinical role of this infection in the context of syndromic management should be clarified.

RESUMEN

BACKGROUND: Men who have sex with men (MSM) are a key population, particularly vulnerable to sexually transmitted infections (STIs) and HIV, but there are limited data on health programs targeting MSM in Africa. This study aims to describe the utilization of nongovernmental organization-supported sexual health services for MSM at 2 public sector health facilities in Johannesburg, South Africa. METHODS: We retrospectively analyzed routine data over the period of January 2014 to June 2016. We report on service utilization for STI syndromes, HIV testing, and the antiretroviral therapy (ART) program. RESULTS: Some 5796 men visited the facilities. Seven thousand one hundred eighty-eight STI episodes were managed, 68.2% (4903 episodes) of which were classified as male urethritis and 9.8% (704 episodes) as genital ulcers. Positivity yield for first-time HIV tests was 38.0% (205 positive test results) in MSM, compared with 14.1% (471 positive test results) in other men. At the end of the study, there were 1090 clients on ART, and 2-year retention was 82% (95% confidence interval, 78%-85%). There was no difference in retention between MSM and other men (P = 0.49). CONCLUSIONS: This study is the first to show that sexual health services targeting MSM in Africa have managed to attract MSM and other men in need of STI and HIV care. The observed high HIV testing yield among MSM illustrates the relevance of MSM-focused services in the South African public health sector, and the good retention on ART demonstrates that high-quality care can be provided to MSM in our setting.

RESUMEN

BACKGROUND: The involvement of Global Health Initiatives (GHIs) in delivering health services in low and middle income countries (LMICs) depends on effective collaborative working at scales from the local to the international, and a single GHI is effectively constructed of multiple collaborations. Research is needed focusing on how collaboration functions in GHIs at the level of health service management. Here, collaboration between local implementing agencies and departments of health involves distinct power dynamics and tensions. Using qualitative data from an evaluation of a health partnership in South Africa, this article examines how organisational power dynamics affected the operation of the partnership across five dimensions of collaboration: governance, administration, organisational autonomy, mutuality, and norms of trust and reciprocity. RESULTS: Managing the tension between the power to provide resources held by the implementing agency and the local Departments' of Health power to access the populations in need of these resources proved critical to ensuring that the collaboration achieved its aims and shaped the way that each domain of collaboration functioned in the partnership. CONCLUSIONS: These findings suggest that it is important for public health practitioners to critically examine the ways in which collaboration functions across the scales in which they work and to pay particular attention to how local power dynamics between partner organisations affect programme implementation.

RESUMEN

Rural South African men who have sex with men (MSM) are likely to be underserved in terms of access to relevant healthcare and HIV prevention services. While research in urban and peri-urban MSM populations has identified a range of factors affecting HIV risk in South African MSM, very little research is available that examines HIV risk and prevention in rural MSM populations. This exploratory study begins to address this lack by assessing perceptions of HIV risk among MSM in rural Limpopo province. Using thematic analysis of interview and discussion data, two overarching global themes that encapsulated participants' understandings of HIV risk and the HIV risk environment in their communities were developed. In the first theme, "community experience and the rural social environment", factors affecting HIV risk within the broad risk environment were discussed. These included perceptions of traditional value systems and communities as homophobic; jealousy and competition between MSM; and the role of social media as a means of meeting other MSM. The second global theme, "HIV/AIDS knowledge, risk and experience", focused on factors more immediately affecting HIV transmission risk. These included: high levels of knowledge of heterosexual HIV risk, but limited knowledge of MSM-specific risk; inconsistent condom and lubricant use; difficulties in negotiating condom and lubricant use due to uneven power dynamics in relationships; competition for sexual partners; multiple concurrent sexual partnerships; and transactional sex. These exploratory results suggest that rural South African MSM, like their urban and peri-urban counterparts, are at high risk of contracting HIV, and that there is a need for more in-depth research into the interactions between the rural context and the specific HIV risk knowledge and behaviours that affect HIV risk in this population.

RESUMEN

We report a case of progressive, cephalosporin-susceptible, Neisseria gonorrhoeae conjunctivitis despite successful treatment of male urethritis syndrome. We hypothesize that conjunctival infection progressed due to insufficient penetration of cefixime and azithromycin and point out that extragenital infection and male urethritis may not be cured simultaneously in settings where the syndromic approach is used.

RESUMEN

OBJECTIVES: To describe the spectrum of ocular complications of herpes zoster ophthalmicus (HZO) in rural South Africa. METHODS: Patients presenting with visual complaints and active or healed HZO at the ophthalmology outpatient department of three hospitals in rural South Africa were included in this study. Demographic and clinical data were collected, and HIV status was determined for all participants. RESULTS: Forty-eight patients were included, and 81% were HIV infected. Poor vision was reported by 94% of patients, painful eye by 79% and photophobia by 63%. A diverse spectrum of ocular complications was observed with corneal inflammation and opacification in 77% followed by anterior uveitis in 65%. The majority (65%) presented with late-stage ocular complications associated with irreversible loss of vision whereas early-stage complications, such as punctate epithelial keratitis and anterior uveitis, were less common. Blindness of the affected eye was observed in 68% of patients with late-stage complications. There was a considerable delay between onset of symptoms and first presentation to the ophthalmology outpatient department (median time 35 days; range 1-2500 days), and longer delay was associated with late-stage ocular complications (P = 0.02). CONCLUSIONS: HZO patients present with relatively late-stage ocular complications, and blindness among these patients is common. The delayed presentation to the ophthalmology outpatient department of hospitals in our rural setting is of concern, and efforts to improve ocular outcomes of HZO are urgently needed.

RESUMEN

OBJECTIVE: To evaluate the performance of three different guidelines for the management of vaginal discharge syndrome (VDS) for women living in a rural setting in South Africa. METHODS: We conducted a secondary analysis of data from a cross-sectional study in Mopani District, South Africa. The 2015 and 2008 guidelines of the South African Department of Health (DoH) and the most recent WHO guidelines were evaluated for adequate treatment of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Trichomonas vaginalis infection. RESULTS: Of the 489 women included in this analysis, 35% presented with VDS according to the DoH and 30% per WHO definition of VDS. Fifty-six per cent of the women with VDS would be treated adequately for these STI when using the 2015 DoH guideline, whereas 76% (P = 0.01) and 64% (P = 0.35) would receive adequate treatment with the 2008 DoH and WHO guidelines, respectively. Of the symptomatic women who tested negative for all four STI, STI treatment would have been indicated for 36% as per 2015 DoH guideline vs. 69% (P < 0.001) per 2008 DoH and 67% (P < 0.001) per WHO guidelines. CONCLUSION: A considerable proportion of symptomatic women infected with these common curable STI would receive adequate treatment when using a syndromic management approach, and significant differences exist between the three guidelines. Many symptomatic women without these STI receive broad-spectrum antibiotics, so new approaches are needed to improve syndromic STI control.

RESUMEN

BACKGROUND: Sexual behaviour is a core determinant of the HIV and sexually transmitted infection (STI) epidemics in women living in rural South Africa. Knowledge of sexual behaviour in these areas is limited, but constitutes essential information for a combination prevention approach of behavioural change and biomedical interventions. METHODS: This descriptive study was conducted in rural Mopani District, South Africa, as part of a larger study on STI. Women of reproductive age (18-49 years) who reported sexual activity were included regardless of the reason for visiting the facility. Questionnaires were administered to 570 women. We report sexual behaviour by age group, ethnic group and self-reported HIV status. RESULTS: Young women (<25 years) were more likely to visit bars, practice fellatio, have concurrent sexual partners and report a circumcised partner than older women (>34 years); there was no difference for condom use during last sex act (36 % overall). Sotho women were more likely to report concurrent sexual partners whereas Shangaan women reported more frequent intravaginal cleansing and vaginal scarring practice in our analysis. HIV-infected women were older, had a higher number of lifetime sexual partners, reported more frequent condom use during the last sex act and were more likely to have a known HIV-infected partner than women without HIV infection; hormonal contraceptive use, fellatio, and a circumcised partner were less often reported. CONCLUSIONS: This study provides insight into women's sexual behaviour in a rural South African region. There are important differences in sexual behaviour by age group and ethnicity and HIV status; these should be taken into account when designing tailor-made prevention packages.
