Renal involvement determines the prognosis of systemic lupus erythematosus (SLE). The aims of this study were to assess the clinical, laboratory and therapeutic aspects of lupus nephritis (LN) in Senegal in order to improve its management. We included all patients presenting with SLE followed-up in the Internal Medicine and Dermatology Clinics of the Aristide Le Dantec University Teaching Hospital of Dakar, from January 1993 to December 2002. Patients with SLE without evidence of LN (defined by proteinuria more than 0.5 g/24 hours and/or hematuria) were excluded. A total of 74 patients with a diagnosis of SLE were studied, 42 of whom (56.75%) had features of LN. Their mean age was 29.6 years and male-female ratio was 0.13. The nephrotic syndrome was seen in 45.23% of the cases and renal insufficiency in 37.71%. Renal biopsy was performed in 52.38% of the cases, which showed predominantly WHO classes IV and V lesions. The main treatment modality employed was corticoste-roids, while immunosuppressive drugs in addition were used in 35.71% of the patients. The short-term prognosis was favorable but in the middle-term, many patients were lost to follow-up. We conclude that early diagnosis by systematic urine screening, good patient information, percutaneous renal biopsy and use of appropriate immunosuppressive therapy will help improving the prognosis of LN in Senegal.
