RESUMO

OBJECTIVES: Macrolide resistance in Mycoplasma genitalium is emerging globally. There is paucity of data from sub-Saharan Africa where syndromic management is used to treat sexually transmitted infections (STIs). We conducted a molecular epidemiological study to determine the prevalence of azithromycin resistance and epidemic diversity of M. genitalium infections in South Africa. METHODS: We analysed 90 M. genitalium-positive specimens that had been collected consecutively from men and women (50% symptomatic) from geographically diverse communities across the northern part of South Africa between 2015 and 2019. Melting curve analysis followed by targeted sequencing of the 23S rRNA gene was performed to detect azithromycin resistance. Molecular typing was done through single nucleotide polymorphism (SNP) analysis of the MG191 gene and short tandem repeats (STR) assessment of the MG309 gene. An overview of all published M. genitalium sequence types was generated and novel sequence types identified in this study were allocated numbers accordingly. RESULTS: Azithromycin resistance was detected in 1/90 M. genitalium-positive specimens (1.1%; 95% CI 0% to 3.3%) as conferred by A2071G mutation; this strain also harboured a C234T mutation in the parC gene with wild type gyrA gene. SNP typing and STR assessment was successful in 38/90 specimens (42%) and showed a genetically diverse epidemic, without geographic clustering, with eight novel sequence types identified. CONCLUSION: This is the first study that determines resistance in M. genitalium infection since introduction of azithromycin in the syndromic management regimen for STIs in South Africa in 2015. Despite a well-established epidemic, azithromycin-resistant M. genitalium infection is still uncommon in the public healthcare sector. However, it has the potential to undermine the effectiveness of syndromic management. Introduction of molecular diagnostics and continuous surveillance are warranted for early detection emergence of resistance.

RESUMO

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.

RESUMO

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.

RESUMO

The FRESHAIR4Life study aims to reduce the non-communicable disease (NCD) burden by implementing preventive interventions targeting adolescents' exposure to tobacco use and air pollution (AP) worldwide. This paper presents the FRESHAIR4Life methodology and initial rapid review results. The rapid review, using various databases and PubMed, aimed to guide decision-making on risk factor focus, target areas, and populations. It showed variable NCD mortality rates related to tobacco use and AP across the participating countries, with tobacco as the main risk factor in the Kyrgyz Republic, Greece, and Romania, and AP prevailing in Pakistan and Uganda. Adolescent exposure levels, sources, and correlates varied. The study will continue with an in-depth situational analysis to guide the selection, adaptation, and integration of evidence-based interventions into the FRESHAIR4Life prevention package. This package will be implemented, evaluated, assessed for cost-effectiveness, and iteratively refined. The research places a strong emphasis on co-creation, capacity building, and comprehensive communication and dissemination.

RESUMO

2·6 billion people rely on solid fuels for cooking or heating. Accelerating access to cleaner solutions is crucial to reduce the negative effects of solid fuel use. Despite abundant evidence on how to implement these solutions, previous attempts have been disappointing. An overview of the evidence is missing and the translation of the evidence into practice is poor. We conducted an umbrella review using eight databases to: consolidate evidence on the factors that influence the implementation of improved solid fuel cookstoves and clean fuels in low-income and middle-income countries; weigh the level of confidence in existing evidence; and develop two practical implementation strategy tools. We identified 31 relevant reviews (13 systematic reviews and 18 narrative reviews) that covered over 479 primary studies. We found 15 implementation factors supported by the highest level of evidence. Regarding improved solid fuel cookstoves, these factors included: cost; knowledge and beliefs about the innovation; and compatibility. For clean fuels these factors included: cost; knowledge and beliefs about the innovation; and external policy and incentives. The factors were synthesised into the Cleaner Cookstove Implementation Tool and the Clean Fuel Implementation Tool. These tools can be used to optimise the implementation of cleaner cooking solutions, thereby improving health, environmental, climate, and gender equity outcomes.

RESUMO

This study from South Africa highlights the importance of rectal Trichomonas vaginalis infection as a sexually transmitted infection among men who have sex with men (MSM). We report seven MSM presenting with rectal T. vaginalis infection. Two men presented with symptoms of proctitis; 5/7 had urethral coinfection with T. vaginalis. Rectal T. vaginalis infection should be considered in MSM in areas where genital infection is endemic.
