    ProblĂ©matique: Comme dans plusieurs pays du Sud, le suivi virologique des patients sous traitement antirĂ©troviral (TARV) en GuinĂ©e est timide voire inexistant dans certaines localitĂ©s. Le but de cette Ă©tude Ă©tait d’évaluer la faisabilitĂ© technique et logistique de l’utilisation des DBS dans les tests de charge virale (CV) et de gĂ©notypage. MĂ©thode: De septembre Ă  octobre 2010, les DBS ont Ă©tĂ© prĂ©parĂ©s Ă  partir de prĂ©lĂšvements sanguins de patients adultes sous TARV. Le dĂ©lai d’envoi des Ă©chantillons au laboratoire de rĂ©fĂ©rence Ă©tait de 30 jours maximum aprĂšs le prĂ©lĂšvement et se faisait Ă  tempĂ©rature ambiante. La CV a Ă©tĂ© quantifiĂ©e et les Ă©chantillons de patients en Ă©chec virologique (CV ≄ 3 log10 copies/mL) ont Ă©tĂ© gĂ©notypĂ©s selon le protocole de l’ANRS. L’algorithme de Stanford version 6.0.8 a Ă©tĂ© utilisĂ© pour l’analyse et l’interprĂ©tation des mutations de rĂ©sistance. RĂ©sultats: Parmi les 136 patients inclus, 129 et 7 Ă©taient respectivement sous premiĂšre et deuxiĂšme ligne de traitement avec une mĂ©diane de suivi de 35 mois [IQR: 6-108]. L’échec virologique a Ă©tĂ© notĂ© chez 33 patients. Parmi eux, 84.8% (n = 28/33) ont bĂ©nĂ©ficiĂ© d’ungĂ©notypage. Le taux de rĂ©sistance global Ă©tait de 14% (n = 19/136). Le CRF02_AG Ă©tait le sous type viral le plus prĂ©valent (82%; n = 23). Conclusion: En plus de montrer la faisabilitĂ© technique et logistique des tests de CV et de gĂ©notypage Ă  partir des DBS, ces rĂ©sultats montrent l’intĂ©rĂȘt de leurs utilisations dans le suivi virologique des patients sous TARV. Cette Ă©tude a permis Ă©galement de documenter l’échec virologique, la rĂ©sistance aux ARV et la diversitĂ© gĂ©nĂ©tique du VIH-1 en GuinĂ©e.

Problem: As in several countries of the South, the virological monitoring of patients undergoing antiretroviral treatment (ARVT) in Guinea is low or non-existent in some locations. The aim ofthis study was to assess the technical and logistical feasibility of the use of (dried blood spots) DBSs in viral load (VL) and genotyping tests. Method: From September 2010 to October 2010, DBS were prepared from blood samples of adult patients under ARVT. The samples had to be sent to the reference laboratory within 30 days after the sample had been done at ambient temperature. The VL was quantified and the samples of patients with virological failure (CV ≄ 3 log10 copies/mL) were genotyped according to the ANRS protocol. The Stanford algorithm, version 6.0.8, was used to analyse and interpret the resistance mutations. Results: Amongst the 136 included patients, 129 and 7 were under first and second line treatment respectively, and monitored for an average of 35 months [IQR: 6-108]. Virological failure was noticed among 33 patients. Among them, 84.8% (n = 28/33) benefited from genotyping. The global resistance rate was 14% (n = 19/136). CRF02_AG was the most prevalent viral subtype (82%; n = 23). Conclusion: In addition to demonstrating the technical and logistic feasibility of VL and genotyping tests from DBSs, these results show the relevance of their use in the virological monitoring of patients under ARVT. Also, this study made it possible to provide informationon virological failure, ARV resistance and the HIV-1 genetic diversity in Guinea

    l’objectif de cette Ă©tude Ă©tait d’évaluer les difficultĂ©s liĂ©es au diagnostic mammographique des affections mammaires au Chu Yalgado ouĂ©draogo de ouagadougou. il s’est agi d’une Ă©tude transversale descriptive menĂ©e du 1er janvier 2007 au 30 juin 2010 et qui a concernĂ© 213 dossiers de patients ayant consultĂ© pour une affection mammaire. nous avons recensĂ© 213 patients dont les dossiers mĂ©dicaux ont Ă©tĂ© retrouvĂ©s avec 95,4 % de femmes et 4,6 % d’hommes soit un sexe ratio de 0,05. la moyenne d’ñge des patients Ă©tait de 41,5 ans et la tranche d’ñge de 43 Ă  52 ans Ă©tait la plus reprĂ©sentĂ©e. la mammographie a pu ĂȘtre rĂ©alisĂ©e seulement par 44 patients soit 20,66 % du fait principalement du coĂ»t exorbitant de l’examen pour les populations majoritairement dĂ©munies, de la faible disponibilitĂ© de cette modalité  d’exploration et de sa faible prescription. les comptes rendus d’examen Ă©taient disponibles chez 27 patients (soit 61,3 %). des anomalies ont Ă©tĂ© retrouvĂ©es chez 73.1 % de ces patients, beaucoup plus chez les femmes (95 %) que chez les hommes (5 %). les lĂ©sions bĂ©nignes Ă©taient l’apanage des tranches d’ñge de 13 Ă  22 ans (68 %) et celles suspectes de malignitĂ© celui des  patients plus ĂągĂ©s, de 43 Ă  52 ans (91 %). les principales lĂ©sions Ă©taient reprĂ©sentĂ©es par les opacitĂ©s (46,1 %) et les  microcalcifications associĂ©es aux opacitĂ©s (11.5 %). on notait une prĂ©dominance des lĂ©sions de type aCR 2 (22,2 %). la  mammographie est l’examen de premiĂšre intention dans le bilan sĂ©nologique mais elle reste relativement peu utilisĂ©e dans notre contexte.Mots-clĂ©s : affections mammaires, diagnostic, mammographie, Burkina Faso. Mammographic screening and diagnostic difficulties of breast diseases at Yalgado Ouedraogo teaching hospital (Chu-Yo) of OuagadougouThe aim of our study was to evaluate difficulties related to  mammographic diagnosis of breast diseases at Yalgado ouedraogo Teaching hospital of ouagadougou (Chu-Yo). This was a   descriptive cross-sectional study conducted from january 1st, 2007 to june 30th, 2010, enrolling 213 folders of patients who had consulted for a breast condition. we identified 213 patients whose medical folders were found, 95.4% were female and 4.6% male with a sex ratio of 0.05. Mean age of patients was 41.5 years and the age group 43-52 years was the most represented.  Mammography could only be performed by 44 patients (20.66%) mainly due to expensive cost of the exam for the majority poor populations as well as limited availability of this imaging  modality and its low request. Mammogram reports were available for 27 patients (61.3%). anomalies were detected in 73.1% of these patients, much more in women (95%) than in men (5%). Benign lesions were confined in 13 to 22 age group (68%) and those suspected for malignancy to older patients aged between 43 and 52 (91%). Main mammographic findings were opacities (46.1%) and microcalcifications associated with opacities   (11.5%). There was a predominance of BiRadS 2 lesions (22.2%). Mammography is the first-line imaging modality in breast diseases screening but it is relatively under-used in our context.Keywords: breast conditions, diagnosis, mammography, Burkina Faso

    Despite the global interest and the unprecedented number of scientific studies triggered by the COVID-19 pandemic, few data are available from developing and low-income countries. In these regions, communities live under the threat of various transmissible diseases aside from COVID-19, including malaria. This study aims to determine the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroreactivity of antibodies from COVID-19 and pre-COVID-19 samples of individuals in Mali (West Africa). Blood samples from COVID-19 patients (n = 266) at Bamako Dermatology Hospital (HDB) and pre-COVID-19 donors (n = 283) from a previous malaria survey conducted in Dangassa village were tested by ELISA to assess IgG antibodies specific to the full-length spike (S) protein, the receptor-binding domain (RBD), and the receptor-binding motif (RBM <sub>436-507</sub> ). Study participants were categorized by age, gender, treatment duration for COVID-19, and comorbidities. In addition, the cross-seroreactivity of samples from pre-COVID-19, malaria-positive patients against the three antigens was assessed. Recognition of the SARS-CoV-2 proteins by sera from COVID-19 patients was 80.5% for S, 71.1% for RBD, and 31.9% for RBM (p < 0.001). While antibody responses to S and RBD tended to be age-dependent, responses to RBM were not. Responses were not gender-dependent for any of the antigens. Higher antibody levels to S, RBD, and RBM at hospital entry were associated with shorter treatment durations, particularly for RBD (p < 0.01). In contrast, higher body weights negatively influenced the anti-S antibody response, and asthma and diabetes weakened the anti-RBM antibody responses. Although lower, a significant cross-reactive antibody response to S (21.9%), RBD (6.7%), and RBM (8.8%) was detected in the pre-COVID-19 and malaria samples. Cross-reactive antibody responses to RBM were mostly associated (p < 0.01) with the absence of current Plasmodium falciparum infection, warranting further study
