P064 Henoch-Schonlein Purpura: experience of a general pediatric center

Background Henoch-Schonlein purpura (HSP) is the most classic dysimmune vasculitis in children, related to an abnormal response of an immature immune system following an external antigen attack. Digestive involvement in HSP conditions the immediate vital prognosis and severe renal failure conditions the long-term functional prognosis. The Objective is to identify the epidemiological, clinical, disease course and therapeutic particularities of patients with HSP with a review of the literature. Material and method The authors reported the results of a retrospective study of cases of patients with HSP hospitalized and treated in the 02 pediatric departments of the wilaya of Annaba in Algeria (Clinique Sainte Thérèse, Annaba hospital university center and EHS El Bouni) over a period of 02 years. Information was obtained from hospital records. Results 24 cases of HSP were identified with a sex ratio of 1.4 (14 boys and 10 girls) and a hospital incidence of 1.66%. The average age was 6.6 years. Half of patients was hospitalized during the autumn-winter period, 67% of whom had an ENT infection before their hospitalizations. 17% of cases have personal history of HSP (the oldest was 5 years ago and the most recent 10 days before hospitalization). 7 patients underwent surgeries prior to hospitalization. Skin lesions were found in all patients. Joint, digestive and renal involvement were recorded in 50%, 80% and 25% respectively. Gastrointestinal bleeding has been observed in one patient. Only 1 patient with renal impairment progressed to chronic renal failure and only 1 patient had confirmed hypertension. A rare association with viral hepatitis A has been noted in one patient. Conclusion HSP remains a benign condition, easy to recognize clinically. Its immediate prognosis depends on the digestive complications and its long-term on nephropathy which may expose to the risk of chronic renal failure.
