ABSTRACT
Clinical features and auto-antibodies profile of 35 Senegalese patients' diagnosed systemic lupus erythematosus (SLE) were analyzed after measurement of antinuclear antibodies (ANA) by IFI, detection of Abs anti-DNA native by ELISA and evaluation of antibodies anti-Sm, anti-RNP, anti-SSA anti-SSB, anti-CCP2, anti-J0, and anti-Scl70 levels by immunodot. Mean age of 33 yrs (18-50 yrs) and sex ratio (F/M) of 16 were found. The most frequent clinical features were rheumatic (88.7%) and cutaneous (79.4%) disorders. ANA and anti-DNAn Abs were detected in 85.7% and 62.5% of the patients respectively. Abs anti-RNP, anti-Sm, anti-SSA, anti-SSB and anti-CCP2 were detected in 30 to 70% of patients. In young patients, the levels of anti-DNAn and anti-Sm Abs were higher than in patients older than 40 yrs (P<0.05). In addition, associations of cutaneous and rheumatic symptoms were characterized by high levels of anti-DNAn, anti-SSA and anti-SSB Abs. Our study shows the interest of a measurement of anti-DNAn, anti-SSA and anti-SSB Abs during the follow of SLE patients particularly in those presenting both rheumatic and cutaneous symptoms.
