Context and objective. DR Congo ranks among high burden countries for tuberculosis. However, the real incidence of the disease is unknown. The study aimed to describe the trends in the estimated incidence of the bacteriologically confirmed pulmonary TB and therapeutic outcomes of patients. Methods. A retrospective analysis of data from TB patients recorded during the period of 2007 to 2017 through all the country. Linear regtression model and z-score helped to assess the year to year variations in notification rate and treatment outcomes. Results. A total of 884,458 patients were enrolled including 820,858 new patients (NP TP+) and 63,600 with a previous TB treatment. The increase reached 28.95% during this decade. The annual average inrease was of 2, 41% +/- 3, and 28 % for NP TP+ and of 5, 7% +/-0.26 for default patients. Treatment outcome assessment included 848,163 patients among them, 789, 716 NP TP+ and 58,447 with a previous TB treatment. The success rate was 88% in the former group, of 70% in those with relapse, 64.3% in patients with failure and 67.8% in the group of ancient defaulters. A total of 70,515 (8.3%) patients remained smear positive. Conclusion. The study shows an increase in the incidence of reported TP+ patients with a treatment outcome reaching the WHO’s expectations. However the high proportion of smear positive patients suggests a high risk of further acquired TB resistance. Contexte et objectifs. La République Démocratique du Congo compte parmi les pays à lourd fardeau pour la tuberculose (TB), l’incidence réelle de la maladie n’est pas formellement connue. La présente étude vise à décrire les tendances de l’incidence notifiée des patients atteints de tuberculose pulmonaire bactériologiquement confirmée (TP+) et leurs issues thérapeutiques. Méthodes. Cette étude documentaire, analyse les données des patients diagnostiqués et traités pour tuberculose de 2007 à 2017 en RDC. L’incidence notifiée des patients TP+, le taux d’accroissement annuel, les issues thérapeutiques ont été recherchés. Les variations du nombre de patients sont exprimées par les proportions. Les tendances sont présentées à travers les courbes de régression linéaire. Les issues thérapeutiques sont comparées à l’aide du z-score avec un seuil significatif de p˂ 0,05. Résultats. Au total 884 458 patients TP+ ont été rapportés, dont 820 858 nouveaux patients (NP TP+) et 63 600 déjà traités. Le taux d’accroissement au cours de cette décade était de 28,95%, soit de 66099 en 2007 à 93767 en 2017 pour les NP TP+. L’augmentation annuelle moyenne était de 2,41% +/- 3,28 pour les NP TP+ et de 5,7% +/- 0,26 par an pour les rechutes. La notification des échecs de traitement initial et repris après abandon de traitement ont une tendance à la baisse. L’évaluation thérapeutique de tous les cas cumulés a concerné 848 163 patients dont 789 716 NP TP+ et 58447 en retraitement. Le succès thérapeutique était de 88,0 % pour les NP TP+ et 70,0 % pour les rechutes, de 64,3 % pour les échecs et de 67,8% pour les repris en traitement après abandon. En somme 70 515 (8,3%) patients ont gardé des expectorations positives. Conclusion. Cette étude montre une tendance à la hausse de notification des cas incidents dont l’issue de traitement répond aux standards de l’OMS. En outre, un nombre des personnes demeurent porteurs de germes persistants précurseurs d’une TB pharmacorésistante acquise.

Context. Atopy is a common feature of asthma, involving near 80% of patients. Allergen sensitization shows environmental and geographical variability worldwide. Objective. To determine the common allergen sensitization profile of adult asthmatics in Kinshasa. Methods. From June 2017 to February 2018, 216 asthmatics aged 18 and over, of both sexes, were consecutively recruited at the University Clinics of Kinshasa and in some parishes and churches around the same town. The socio-demographic variables were registered using a validated questionnaire. The prick-test was performed relaying on five standardized commercial extracts of dog and cat dander, house dust mite (Blomia tropicalis, Bt), molds (Alternaria alternata), and egg yolk. Results. The population, average age of 45.23 (SD=17.56) years, 74% female, was sensitized at least to one allergen (53%) and non -sensitized in 47%. Twenty-five percent were monosensitized and 27% plurisensitized. The sensitization profile was respectively to Blomia tropicalis (72%), cat dander (46%), dog dander (34%), Alternaria alternata (13%) and egg yolk (11%). Conclusion. The present study indicates a plurisentisization feature in many asthmatics in our milieu ; mainly to dust mites and cat dander. Futher investigations involving a larger number of subjects and using broader test batteries are needed to improve diagnostic and therapeutic approaches in our context. Contexte. Environ 80% des asthmatiques sont atopiques. La sensibilisation aux allergènes communs présente certaines variabilités environnementales et géographiques. Objectif. Déterminer le profil de sensibilisation aux allergènes communs des asthmatiques adultes de la ville de Kinshasa. Méthodes. De juin 2017 à février 2018, 216 asthmatiques de 18 ans et plus, des 2 sexes, ont été consécutivement recrutés aux Cliniques Universitaires de Kinshasa et dans certaines paroisses et églises de réveil de la ville de Kinshasa. A l’aide d’un questionnaire validé, les variables sociodémographiques ont été précisées. Le prick-test a été réalisé avec cinq extraits commerciaux standardisés de phanères de chien et chat, l’acarien de poussière de maison (Blomia tropicalis, Bt), les moisissures (Alternaria alternata), et le jaune d’oeuf. Résultats. L’âge moyen de la population était de 45,23 (ET=17,56) ans, 74% de sexe féminin, 47 % non sensibilisés et 53% sensibilisés à au moins un allergène. Vingt-cinq pourcent étaient monosensibilisées et 27% plurisensibilisées. Le profil de sensibilisation était Blomia tropicalis (72%), phanères de chat (46%), phanères de chien (34%), Alternaria alternata (13%) et jaune d’oeuf (11%). Conclusion. Une plurisensibilisation aux allergènes communs chez les asthmatiques dans notre milieu est présente dont le profil dominé par les acariens et les phanères de chats. Des enquêtes futures incluant un plus grand nombre de sujets et recourant à des batteries de tests plus élargies s’imposent en vue d’une définition d’options diagnostiques et thérapeutiques dans notre contexte.

Context and objective. Cardiometabolic risk factors profile of flight and cabin crew has never been previously assessed in low-resource settings such as sub-Saharan African countries. The present study aimed to evaluate the prevalence of hypertension, its determinants, and associated cardiometabolic risk factors among flight and cabin crew. Methods. A total of 379 aircrew members, 112 women (29.6%) and 88 Caucasians (23.2%) of whom 237 flight crew (62.5%) including 175 pilots (46.2%) and 142cabin crew (35.5%) underwent a medical examination for either initial or renewal medical certificate Class I or II as per the ICAO and the CAA/DRC recommendations including blood chemistry, ECG, and echocardiogram. Results. Much more prevalent (p

Context. Little is known about therapeutic successes in MDR-TB patients under regimens containing second-line molecules. The present study aimed to assess therapeutic outcomes in patients under therapeutic regimens applied in DR Congo. Methods. This historical cohort study has included confirmed MDR-TB patients who received treatment between 2007 and 2017 in 218 TB centers in DR Congo. Treatment outcome and survival at 36 months were analyzed using Zscore and chi square test. Kaplan-Meier method was performed to describe survival and Log Rank test helped in comparing curve based on the therapeutical regimen. Factors associated with therapeutic success and mortality predictors were assessed using multivariate logistic regression and Cox regression analysis, respectively. Results. The therapeutic success in the study group (n=1,724) was 72% (range 68-74%) for all regimen combined. The average death rate was 12.8% although the group of patients receiving Cyclosérine and Ofloxacine was the most affected (16%). The death rate was significantly higher in patients living in urban areas (15.2% versus 14.9%, p = 0.013) and also among MDR-TB/HIV co-infected patients (28.4% vs 15.7%, p

Objectives To examine family planning outcomes among women living in military camps in Kinshasa, Democratic Republic of the Congo, and compare these outcomes with a representative sample of non-military women in Kinshasa. Participants Women of reproductive ages, 15–49 years. We compare two populations: women living in military camps and the general (non-military) population in Kinshasa. Study design For sampling, we used a two-stage cluster sampling design, where we first randomly selected enumeration areas (EA), and then randomly selected women within each EA (separately for each of the two populations). We administered a survey on contraceptive use and family planning to all participating women. We use bivariate and multivariate analysis to compare these populations for a range of family planning outcomes. Results We find many statistically significant differences between women in military camps and general female population of Kinshasa. Although they do not have more children, women in military camps are less likely to be using contraception (all methods OR 0.24, 95% CI 0.11 to 0.53; modern methods OR 0.25, 95% CI 0.08 to 0.79; traditional methods OR 0.41, 95% CI 0.24 to 0.71) and less knowledgeable about many family planning methods (less likely to have heard of implants (OR 0.23, 95% CI 0.11 to 0.48), injectables (OR 0.19, 95% CI 0.08 to 0.44), condoms (OR 0.23, 95% CI 0.12 to 0.47), withdrawal (OR 0.05, 95% CI 0.02 to 0.17) and rhythm (OR 0.12, 95% CI 0.03 to 0.44) methods), while at the same time they are more likely to want to limit their births (OR 5.17, 95% CI 2.52 to 10.62), and less likely to have obtained their preferred family planning method (OR 0.14, 95% CI 0.03 to 0.64). Conclusions Women in military camps in Kinshasa appear to be an important and underserved population with regard to family planning. Our results suggest that women in military camps have limited access to modern family planning methods.
