Objectives To estimate the prevalence of oral mucosal diseases and dental caries among HIV-infected children receiving antiretroviral treatment (ART) in West Africa, and to identify factors associated with the prevalence of oral mucosal lesions. Methods Multi-center cross-sectional survey in 5 pediatric HIV clinics in Côte d’Ivoire, Mali and Sénégal. A standardized examination was performed by trained dentists on a random sample of HIV-infected children aged 5 to 15 years receiving ART. The prevalence of oral and dental lesions and mean number of decayed, missing/extracted and filled teeth (DMFdefT) in temporary and permanent dentition were estimated with their 95% confidence interval (95%CI). We used logistic regression to explore the association between children’s characteristics and the prevalence of oral mucosal lesions, expressed as prevalence odds ratio (POR). Results The median age of the 420 children (47% females) enrolled was 10.4 years (interquartile range [IQR]=8.3–12.6). The median duration on ART was 4.6 years (IQR=2.6–6.2); 84 (20.0%) had CD4 count<350 cells/mm3. 35 children (8.3%; 95%CI: [6.1–11.1]) exhibited 42 oral mucosal lesions (24 were candidiasis); 86.0% (95%CI=82.6–89.3) of children had DMFdefT≥1. The presence of oral mucosal lesions was independently associated with CD4 count<350 cells/mm3 (POR=2.96, 95% CI=1.06–4.36) and poor oral hygiene (POR=2.69, 95%CI=1.07–6.76). Conclusions Oral mucosal lesions still occur in HIV-infected African children despite ART, but rarely. However, dental caries were common and severe in this population, reflecting the need to include oral health in the comprehensive care of HIV.

Although preventable, the burden of dental disease was high in children from families affected by HIV in West Africa and was associated with HIV infection and immunosuppression.

BackgroundWorldwide, female sex workers (FSW) represent a vulnerable population for oral diseases due to many risk factors including HIV infection and drug abuse. In sub-Saharan Africa, little is known about the burden of oral diseases and their determinants in vulnerable populations. The aim of the study was to estimate the prevalence and associated factors of oral diseases among FSW.MethodsA cross sectional study was conducted among FSW who attended a dedicated non-profit clinic in Abidjan, Côte d’Ivoire from June to August 2013. Data about the presence of dental caries, periodontitis and oral-mucosal lesions were collected by a dentist during an oral examination. Behavioural information related to oral hygiene habits as well as tobacco and alcohol consumption were collected through a standardized questionnaire. Information related to HIV infection including HIV diagnosis, last known CD4 count and antiretroviral therapy were documented through a medical chart review. Logistic regression models were used to identify factors associated with oral diseases.ResultsA total of 249 FSW with a median age of 29 years, [Inter Quartile Range (IQR) = 23–36] and a median duration of sex work of 24 months [IQR 9–60]) were included. Current tobacco use and hazardous alcohol use were reported in 21.7 % and 19.7 % of FSW, respectively. The estimated prevalence of HIV infection was 33.7 % [95 % confidence interval (CI); 27.8 – 39.6]) and 82.1 % of HIV-infected FSW were on antiretroviral therapy . The prevalence of dental caries, periodontitis and oral-mucosal lesions were 62.3 % [95 % CI 55.5 – 67.5], 14.5 % [95 % CI 10.2 – 18.9] and 8.2 % [95 % CI 4.8 – 11.5], respectively. In multivariate analysis, periodontitis, oral-mucosal lesions and HIV infection were associated with odds ratio of 2.6 [95 % CI, 1.2–5.8]) and 50.0 [95 % CI; 6.4–384.6].ConclusionsThis study showed a high prevalence of oral diseases among FSW in Abidjan. HIV infection was common and significantly associated with periodontal diseases and oral-mucosal lesions. There is a need to integrate regular screening and treatment of oral lesions into the medical follow-up of FSW along with strategies for HIV prevention.Electronic supplementary materialThe online version of this article (doi:10.1186/s12903-015-0129-0) contains supplementary material, which is available to authorized users.

The impact of antiretroviral therapy in HIV-infected children has raised novel challenging questions in the field of oral health warranting future research.

Setting Drug resistance threatens tuberculosis (TB) control, particularly among HIV-infected persons. Objective We surveyed antiretroviral therapy (ART) programs from lower-income countries on prevention and management of drug-resistant TB. Design We used online questionnaires to collect program-level data in 47 ART programs in Southern Africa (14), East Africa (8), West Africa (7), Central Africa (5), Latin America (7) and Asia-Pacific (6 programs) in 2012. Patient-level data were collected on 1,002 adult TB patients seen at 40 of the participating ART programs. Results Phenotypic drug susceptibility testing was available at 36 (77%) ART programs, but only used for 22% of all TB patients. Molecular drug resistance testing was available at 33 (70%) programs and used for 23% of all TB patients. Twenty ART programs (43%) provided directly observed therapy (DOT) during the whole treatment, 16 (34%) during intensive phase only and 11 (23%) did not follow DOT. Fourteen (30%) ART programs reported no access to second-line TB regimens; 18 (38%) reported TB drug shortages. Conclusions Capacity to diagnose and treat drug-resistant TB was limited across ART programs in lower income countries. DOT was not always implemented and drug supply was regularly interrupted, which may contribute to the global emergence of drug resistance.

IntroductionLes établissements de santé (ES) possèdent-ils les ressources de base pour la prise en charge des cas de paludisme? L’objectif de notre étude était d’analyser la Capacité Opérationnelle (CO) des ES de première ligne de la Côte d’Ivoire dans la prise en charge du paludisme.MéthodesLa méthodologie SARA a été utilisée pour réaliser une étude transversale descriptive du 10 au 30 juillet 2016. La CO pour la prise en charge du paludisme a exprimé la disponibilité moyenne de 9 éléments traceurs répartis en 3 domaines: (i) personnel et directives; (ii) capacité de diagnostic; (iii) médicaments et produits. Cette CO a été évaluée par le calcul d’un indice puis comparé entre les ES selon l’instance gestionnaire et la zone géographique à l’aide du test du Chi2 pour un risque de première espèce α fixé à 0,05.RésultatsParmi les 818 ES, 651(79,6%) étaient du secteur public et 487(59,5%) situés en zone rurale. La CO des ES de première ligne était de 74,5%. Cette CO était plus élevée dans le public (81,3%) que dans le privé (48,8%) (p < 10-3) ainsi qu’en zone rurale (82,7%) par rapport à la zone urbaine (62,9%) (p < 10-3).ConclusionLes ES de première ligne de la Côte d’Ivoire disposaient en 2016 des ressources de base pour une prise en charge des cas de paludisme. Il est nécessaire de mettre l’accent sur le renforcement du système de santé dans son ensemble en plus de la prévention.

Introduction several adverse pregnancy outcomes have been reported in gestations with associated hypothyroidism. The prevalence of hypothyroidism has not been frequently reported in Black Africans. This study sorts to report the prevalence and associated factors of hypothyroidism in Black African pregnant women. Methods this was a hospital-based cross-sectional study, including all pregnant women attending the gynecologic unit of Bouget General Hospital Abidjan. Serum thyroid-stimulating hormone and T4 were obtained from all participants and analyzed using a fluorescent Immunochemistry assay. Data were analyzed using R version 4.05. Univariable and multivariable logistic regression was used to assess factors associated with hypothyroidism and statistical significance considered as p < 0.05. Results overall there were 693 participants, mean age of 28.1(SD 6.4) years with an average gestational age of 24.1 (SD 8) weeks, and a majority of study participants were in the second trimester of gestation. The prevalence of hypothyroidism was 12.1% (n = 84) (10.8% subclinical hypothyroidism and 1.3% clinical hypothyroidism) whereas 1.9% (n = 13) had hyperthyroidism. In addition, patients with reported type 1 diabetes mellitus had an increased risk of hypothyroidism (aOR: 12.6, 95% CI 1.9-100.8; p ≤ 0.01). Conclusion this study revealed a high prevalence of hypothyroidism, though mostly in the subclinical form. Further research is warranted to confirm these findings which may have implications on early screening of hypothyroidism in black African women.
