ABSTRACT: 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.
