RESUMO
Introduction : La pandémie de covid-19 a eu un impact sur les systèmes de santé, entravant la prise en charge optimale des maladies chroniques. L'objectif de notre étude était d'évaluer son impact sur le suivi des pathologies systémiques. Patients - Méthodes : Nous avons mené une enquête transversale multicentrique dans les services de Médecine Interne, de Rhumatologie et de Néphrologie à Dakar. Les patients étaient inclus en accord avec les critères de consensus internationaux. L'enquête a porté sur les dossiers concernant 13 questions et a été complétée par un entretien téléphonique avec 38 questions potentielles. Les réponses étaient collectées grâce à une application Web puis exportées et analysées avec le logiciel SPSS 26.0. Résultats : Du 1er Août au 31 Octobre 2021, 131 patients ont été inclus avec un âge moyen de 41,5 ans (+/-12,4) et un sex-ratio de 0,08. Les pathologies inflammatoires étaient dominées par la polyarthrite rhumatoïde (47,3%) et le lupus systémique (22,9%). Les patients ont rapporté avoir raté un ou plusieurs rendez-vous de suivi dans 45% des cas. Les motifs étaient dominés par une difficulté d'obtenir un rendez-vous de suivi (18,6%) et la peur de fréquenter les hôpitaux (16,9%). Une rupture médicamenteuse a été notée dans 33,6% des cas et concernait notamment l'hydroxychloroquine (40,9%) ou le méthotrexate (47,7%) avec comme raison principale les ruptures de stock en pharmacie et les difficultés économiques. Une poussée de la maladie systémique a été rapportée dans 31% des cas corrélée à la rupture médicamenteuse. Onze (11) patients ont présenté une infection confirmée à SARS CoV-2. Conclusion : La pandémie de covid-19 a eu un impact non négligeable sur le suivi des patients atteints de maladies inflammatoires systémiques. Elle a mis en exergue l'intérêt de la réorganisation de la prise en charge de ces patients en période de crise sanitaire, l'éducation thérapeutique des patients et le recours à la télémédecine pour assurer la continuité des soins.
Introduction: The covid-19 pandemic has had an impact on health systems, compromising the optimal management of chronic diseases such as systemic autoimmune and autoinflammatory diseases. The aim of our study was to assess its impact on the follow-up of systemic diseases in Dakar. Patients - Methods: We conducted a multicentre cross-sectional survey in the departments of Internal Medicine, Rheumatology and Nephrology in Dakar. Patients were included in accordance with international consensus criteria. The survey was based on records of 13 questions and was completed by a telephone interview with 38 potential questions. Responses were collected using a web-based application and then exported and analyzed using SPSS 26.0 software. Results: From 1 August to 31 October, 131 patients were included with a mean age of 41.5 years (+/-12.4) and a sex-ratio of 0.08. Inflammatory diseases were dominated by rheumatoid arthritis (47.3%) and systemic lupus erythematosus (22.9%). Patients reported missing one or more follow-up appointments in 45% of the cases. The reasons were dominated by difficulty in obtaining a follow-up appointment (18.6%) and fear of attending hospitals (16.9%). A drug shortage was also reported in 33.6% of the cases and concerned in particular hydroxychloroquine (40.9%) or methotrexate (47.7%), with the main reason being stock shortages in pharmacies and economic difficulties. A flare-up of the systemic disease was reported in 31% of the cases correlated with the drug rupture. Only 11 patients had a confirmed SARS CoV-2 infection. Conclusion: The covid-19 pandemic has had a significant impact on the follow-up of patients with systemic inflammatory diseases. It highlighted the interest of reorganizing the follow-up of these patients during a health crisis, the patient education and the use of telemedicine to ensure continuity of care

Doenças Autoimunes , COVID-19RESUMO
Using culturomics methods, three strains were isolated, identified and characterized following the taxonogenomics concept. Clostridium cagae strain Marseille-P4344T (=CSURP4344), Clostridium rectalis strain Marseille-P4200T (=CSURP4200) and Hathewaya massiliensis strain Marseille-P3545T (=CSURP3545) were isolated from human stool samples. The phylogenetic reconstruction, phenotypic criteria and genomic analyses were carried out and demonstrated that these three bacteria are different from previously known bacterial species with standing in nomenclature and were classified as new members of the Clostridiaceae family.
RESUMO
Massilistercora timonensis gen. nov., sp. nov. strain Marseille-P3756T is a new species of the phylum Firmicutes; it was isolated from the human gut microbiota and has a genome of 2 769 591 bp (51.2% G + C). The closest species based on 16S rRNA sequence was Merdimonas faecis strain BR31 with 95.2 % sequence similarity. Considering phenotypic features and comparative genome studies, we proposed the strain Marseille-P3756T as the type strain of Massilistercora timonensis sp. nov., a new species within the genus Massilistercora.

RESUMO
BACKGROUND: The association of macrophage activation syndrome and primary Sjögren's syndrome has been rarely reported in the literature. We report the first observation of this association in Africa, south of the Sahara, and we discuss the diagnosis and therapeutic challenge. CASE PRESENTATION: A 26-year-old Mauritanian and Berber woman was followed for primary Sjögren's syndrome. After a voluntary cessation of her usual background treatment, she was admitted to our department for an outbreak of her illness. A clinical examination revealed anemic syndrome, peripheral polyarthritis, coughing rales at both pulmonary bases, and fever at 39.5 °C. On biologic examination, there was bicytopenia with anemia at 5.70 g/dl, lymphopenia at 796/mm3, a biological inflammatory syndrome with a sedimentation rate at 137 mm in the first hour, C-reactive protein at 97 mg/l, hyperferritinemia at 1778 mg/l (9 normal value), and hypergammaglobulinemia at 20.7 g/l of polyclonal appearance. The triglycerides were 1.95 g/l (1.4 normal value) and the lactate dehydrogenase level was 491 IU/l (1.5 normal value). Cytological examination of a medullary puncture revealed an image of hemophagocytosis. An infectious screening was negative. Thoracic computed tomography showed non-specific interstitial lung disease. A diagnosis of macrophage activation syndrome complicating primary Sjögren's syndrome was selected with a probability of 97.2%, according to H-Score. The evolution was favorable under a treatment including etoposide (VP-16). CONCLUSION: Macrophage activation syndrome is a rare entity, rarely reported during primary Sjögren's syndrome. Its spontaneous evolution is invariably fatal. There is no consensus on therapeutic treatment. Etoposide is a therapeutic option especially in forms refractory to corticosteroid therapy.

Xanthomonas massiliensis strain SN6T is a Gram-negative bacterium which is aerobic, motile and nonsporulating. This new species isolated from human faeces exhibited the characteristic traits of members of this genus, such as yellow pigmentation and viscosity.

RESUMO
The taxonogenomic approach, including the culturomics techniques, is now currently used to isolate and characterize new bacteria. These approaches notably allowed us to discover six new species of the Actinomyces genus: Actinomyces ihuae strain SD1, Actinomyces bouchesdurhonensis strain Marseille-P2825, Actinomyces urinae strain Marseille-P2225, Actinomyces marseillensis strain Marseille-P2818, Actinomyces mediterranea strain Marseille-P3257 and Actinomyces oralis strain Marseille-P3109. Each is the type strain of the corresponding bacterial species. 16S ribosomal RNA gene sequence comparison was used to classify these strains among the Actinomyces genus. These strains are all Gram positive, rod shaped and facultative aerobic. We describe the main characteristics of each bacterium and present their complete genome sequence and annotation.
