Panorama of Autoimmune and Autoinflammatory Diseases in Internal Medicine at the University Hospital Center (UHC) of the Point G

Introduction: Panorama studies of autoimmune and auto-inflammatory diseases are still very little carried out in Africa and particularly in Mali. The objective of this descriptive study with retrospective collection was to describe the epidemiological and clinical profile of all autoimmune and auto-inflammatory diseases in the department of internal medicine at the University Hospital Center of the Point G. Methods: This was a descriptive study with a retrospective survey of the records of patients hospitalized for autoimmune and auto-inflammatory diseases in the department of internal medicine at the CHU of Point G for a study period of 15 years from January 1, 2005 to December 31, 2019. We included in the study all patients hospitalized for autoimmune and auto-inflammatory diseases. Results: During the study period (January 31, 2005 to December 31, 2019), 6383 patients were hospitalized in internal medicine at the University Hospital Center of the Point G, of which 317 patients presented with autoimmune and/or auto-inflammatory disease with an average annual hospital recruitment rate of 21 ± 7.87 cases per year. The female sex accounted for 64.98% with a sex ratio of 0.54. The mean age of patients was 35.27 ± 16.27 years and the extreme ages were 07 and 79 years. Out of the 317 medical records included according to our inclusion criteria, there were 07 cases of association between autoimmune disease and autoinflammatory disease, i.e. 14 cases of autoimmune and autoinflammatory diseases. A total of 331 autoimmune diseases and/or auto-inflammatory diseases were collected, i.e. a frequency of 5.19%, including 291 cases of autoimmune diseases (221 cases of organ-specific autoimmune diseases and 70 cases of systemic autoimmune diseases) and 40 cases of autoinflammatory diseases (no case of monogenic forms, 08 cases of “systemic” polygenic forms and 32 cases of “organ-specific” polygenic forms). Organ-specific autoimmune diseases were dominated by type 1 diabetes (141 cases), Graves’ disease (48 cases) and systemic autoimmune diseases by systemic lupus erythematosus (43 cases), rheumatoid arthritis (16 cases). Among the auto-inflammatory diseases, the “systemic” polygenic forms were dominated by Horton’s disease (02 cases) and the “organ-specific” polygenic forms by gout (16 cases), ulcerative colitis (08 cases). Conclusion: It appears from our study that autoimmune and autoinflammatory diseases are characterized in internal medicine by their frequent occurrence in women and preferably between 25 and 44 years of age with very disparate distribution. We also observed a predominance of organ-specific autoimmune diseases over systemic ones, and “organ-specific” polygenic autoinflammatory diseases over “systemic” ones.

Pericarditis in Cardiology at a Regional Hospital

Introduction: Pericarditis is an inflammation of the pericardium with or without pericardial fluid effusion. Its prevalence is difficult to determine given the many forms that are not symptomatic. In Africa, its prevalence was 6.3% in Gabon in 2020 and 7.2% in Mali in 2022. In Europe, an Italian study estimates the incidence of acute pericarditis at 27.7 cases per 100,000 people per year. In another study conducted in Finland over a period of 9 years, the incidence of pericarditis requiring hospitalisation was 3.32 cases per 100,000 people per year. The aim of our study was to describe the clinical and paraclinical characteristics of pericarditis observed in the cardiology department of the regional hospital in Mali. Methodology: This was a single centre cross-sectional study from 30 January 2018 to 30 June 2020 in the cardiology department of the Ségou regional hospital. All consenting patients, regardless of age or sex hospitalised in the department for pericarditis confirmed on cardiac ultrasound were included. Data were collected using an individual patient follow-up form recording sociodemographic, clinical, biological, electrocardiographic and echocardiographic data, as well as the course of the disease. Results: Out of 879 patients hospitalized, the hospital frequency was 7.28%. Females predominated, with a sex ratio of 0.42. More than half the patients were aged 45 or younger (59.4%). The mean age of patients was 41.8 ± 18.1 years. Cardiovascular risk factors were dominated by hypertension and smoking (46.9% and 12.5% respectively). The reasons for consultation were dyspnoea (84.3%), chest pain (54.7%), cough (71.9%) and fever (34.4%). Physical signs included muffled heart sounds (76.6%), tachycardia (70.3%), pericardial friction (17.2%) and signs of peripheral stasis in 53.1% of cases. We observed elevated C-reactive protein (CRP) in 57.8% of cases, hypercreatininaemia in 37.5% and positive HIV serology in 3.1%. The major radiographic signs were cardiomegaly in 82.8% and pleural effusion in 37.5%. On electrocardiogram (ECG), 51.6% of patients had a repolarisation disorder and sinus tachycardia;34.4% had QRS microvoltage. Echocardiography revealed tamponade in 1.6% and pericardial effusion in 100%. The effusion was very large in 17.3% of cases. The pericardial fluid was citrine yellow in 18.8%, serosanguineous in 9.4% and haemorrhagic in 7.8%. The aetiology of the pericarditis was idiopathic in 42.1% and secondary to HIV in 3.1%. Transudative fluid was observed in 16.5% of cases. The outcome was generally favourable, with 92.2% of cases cured, but 1.6% with persistent effusion, 3.1% with recurrence, and 3.1% with mortality.
