[Frequency of hematological and immunological manifestations of lupus in Dakar].
BACKGROUND
The systemic erythematosus lupus (SEL) or lupic disease is a systemic auto-immun pathology characterized primarily by the presence of antibodies directed against native antibodies anti-DNA. The discovery circumstances of diagnosis are variable and polymorphic. The hematologic signs and the immunological disorders constitute the diagnosis criteria of the lupic disease.


METHODS
It is a multicentric and retrospective study undertaken study from January 1, 1997 to September 30, 2006. Patients were followed up in the Internal Medicine of Dakar. We have studied the hematological and immunological aspects of the SEL and have evaluated the prevalence of lupic disease.


RESULTS
142 patients with lupic disease were included with 125 women and 17 men; the ratio--sex was 0.13. The mean age was 34 years with extremes of 6 and 72 years. Our patients had hematological and immunological manifestations in 32.4% and 76.8% of the cases. The immunological tests showed the presence of antinuclear antibodies in 97.9% of the cases, native antibody anti-DNA in 45.7% of the cases, the anti-ECT in 8.95% (with the anti-RNP in 78.3 % of the cases, anti-Sm in 56.5% and of anti-SSA in 87% of the cases). Antibodies anti-DNAand anti-ECT were associated the hematologic demonstrations respectively in 92% and 95% of the cases (p 0.08).


CONCLUSIONS
The hematologic and immunoligical signs of lupus disease are frequent and constitute diagnostic criteria of the disease.
