The diagnosis of RA is delayed in Senegal, and the disease is highly active at diagnosis, although 44 patients have no erosions, and extra-articular manifestations are rare.
The risk of venous thromboembolism was frequent in hospitalized patients in Senegal but only a few received the recommended prophylaxis. There is a need to implement a programme to improve venous thromboembolism awareness and prophylaxis.
Authors report a 37-year-old Senegalese woman with no known history of nephropathy who was admitted for fever related to malaria, severe acute renal failure requiring dialysis with nephrotic syndrome. Biological examinations and bone marrow aspiration showed hemophagocytic syndrome. A kidney biopsy found a 'collapsing glomerulopathy' (CG). A protracted course of steroids yielded a complete, unexpected remission of the nephrotic syndrome and renal function was normal at 18 months.
Several studies have suggested that rheumatoid arthritis (RA) is uncommon in rural sub-Saharan Africa. The aim of this study is to determine the potential differences between patients with RA living in rural areas and those living in urban areas. We performed a cross-sectional study from June 2006 to May 2009. We included all patients with RA (1987 ACR criteria) seen at the Rheumatology Unit of the Le Dantec Teaching Hospital, Dakar, Senegal. We compared the main socio-demographic and clinical characteristics of patients living in rural areas to those living in urban areas. We included 180 patients in our study, of whom, 143 (79.4 %) lived in urban areas and 37 (20.6 %) in rural areas. The median age was 44 years [range 34-55] in patients from rural areas vs. 41 years [range 30-53] in patients from urban areas, without any statistical significance (p = 0.24). Patients under the age of 60 mostly lived in urban areas (p = 0.03). The extra-articular manifestations were significantly more frequent in patients living in rural areas (p = 0.02). There was no statistical significance when comparing the delay in diagnosis, number of swollen joints, disease activity, hand deformities, and concentration of autoantibodies (RF and ACPA) in both populations. The percentage of patients seen from the rural areas of Senegal is low (20.6 %) compared to those seen from the urban areas. The number of extra-articular manifestations is the main difference between patients living in rural and urban areas. The role played by environmental factors seems important. Further incidence studies are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
