In the era of biotherapies and the arrival of biosimilars in sub-Saharan Africa, the objective of this study was to describe plasma IL-6 variations in RA patients at Cité Verte District Hospital (Cameroon). Material and Methods: Descriptive and analytical cross-sectional study from December 1, 2021 to May 31, 2022. We included patients over 18 years old suffering from RA (ACR/EULAR 2010). Patients with an infection were not included. The data collected were age, sex, smoking status, family history, disease duration, disease activity by DAS28, CRP, rheumatoid factor, and plasma level of IL-6. Bone erosion was sought on radiography and ultrasound. Result: We included 31 patients, 25 of whom were women (80.6%). The mean age was 47.27 ± 17.97 years. Disease activity was predominantly moderate (32.3%) and severe (32.3%). Mean IL-6 level was 15.29 ± 2.36 pg/ml (extremes: 11.26 pg/ml and 20.15 pg/ml). IL-6 levels were higher in patients with a history of smoking. Similarly, IL-6 levels were higher in patients with mildly active RA in remission than in moderately and severely active RA. Mean IL-6 levels were significantly higher in patients with erosive RA (16.3 pg/ml VS 14.6 pg/ml). Conclusion: IL-6 levels were significantly elevated in men, weaned smokers and patients with bone erosions.展开更多

Patients and Methods: Retrospective descriptive study over eight years (January 2005 to December 2012) of patients seen for CRD in rheumatology hospitalization at the CHU de Cocody in Abidjan, Côte d’Ivoire. Results: Of 3147 hospitalized patients, 92 had CRD, a frequency of 2.9%. The mean age of patients was 43.50 ± 15.6 years (extremes: 10 to 79 years). The sex ratio was 0.08 (7 men and 85 women). The socio-economic level was low in 44 patients (47.8%), medium in 44 patients (47.8%), and high in 4 patients (4.4%). The reasons for consultation were polyarthritis (64.1%), polyarthralgia (30.4%), and oligoarthritis (5.4%). The mean duration of symptomatology was 19 months (range: 3 to 20 years). The mean length of hospital stay was 14.2 ± 7.7 days (range: 2 to 36 days). The CRD observed were: rheumatoid arthritis (59.8%), systemic lupus erythematosus (23.9%), mixed connective tissue disease (6.5%), undifferentiated connective tissue disease (3.3%), polymyositis (3.3%), systemic scleroderma (2.2%), and systemic vasculitis (1%). Conclusion: CRD is not uncommon in rheumatology hospitals in Abidjan. Diagnostic delays are long, and rheumatoid arthritis and systemic lupus erythematosus are the most frequently encountered conditions.展开更多

It is frequently accompanied by general signs and cardio-vascular, rheumatologic, and digestive complications. Its management is essentially based on the use of corticosteroids and immunosuppressants. The outcome of the treatment, even if rapid, does not always avoid functional complications. This disease is probably under-diagnosed in Africa. Objective: The objective of this study was to report a case of Cogan syndrome in sub-Saharan Africa. Case report: A 78 year old black African female patient presented with arthritis of the left knee without fever. The examination also revealed a bilateral deafness of rapidly progressive onset. The patient was known to be diabetic and hypertensive, and was regularly monitored. The biology revealed an inflammatory syndrome and an inflammatory joint puncture fluid. Pure tone audiometry confirmed a 77% hearing loss. The ophthalmological examination revealed stromal oedema and hypertensive retinopathy of Kendall stage III. The rheumatological evolution was good under methylprednisolone and methotrexate, but the deafness persisted. The occurrence of a fever on day 12 of treatment required further investigations (blood culture, PCR-Covid 19 test, cytobacteriological examination of sputum, thoracic CT). The evolution was unfavourable with the death of the patient. Conclusion: Cogan’s disease is a rare inflammatory disease. Its diagnosis and management are multidisciplinary. The treatment can be disappointing.展开更多
