PReS-FINAL-2304: Systemic lupus erythematosus in childhood: experience of single center (data of last ten years)

Results Of the 90 subjects, 79 were female and 11 were male. Mean age at the onset of disease was 10.2 ± 2.9 years (range 3.1-16 years), and mean age at the time of diagnosis was 11.6 ± 3 years (range 3,8-16 years). Twenty two (24.4%) of the subjects had been followed up initially with a different diagnosis. Eighty (88.8%) of the patients had malar rash, 32 (35.6%) had oral ulcer, 55 (61.1%) had a non-deforming polyarthritis, 12 (13.3%) had serositis (7 pericarditis and 5 pleuritis). None of the patients developed avascular necrosis. Thirty eight (42.2%) of the patients had renal involvement. Of the patients with renal involvement, 5 progressed to end stage renal disease requiring hemodialysis. These 5 patients were those who were noncompliant with their periodic controls. Seventeen (18.8%) patients had neurologic involvement. None of the patients developed any irreversible neurologic sequela. At the onset of diagnosis, 88 (97.7%) of the patients had ANA positivity. Twelve (13.3%) of the patients had a family history of autoimmune disease. Ten patients developed secondary antiphospholipid syndrome during follow up. All of the patients were given corticosteroid treatment at varying doses. Patients with renal involvement were given cyclophosphamide therapy. Azathioprine and mycophenolate mofetil were used in 62 and 19 patients, respectively. The mean durations of follow up were 62 months (range 12-120 months). Three patients died during the follow up period (due to sepsis, antiphospholipid syndrome, eosaphageal varices hemorrhage). Patients who were over 20 years of age were transferred to adult rheumatology department.
