According to existing database, there were a total of 181 patients, 101 of them (55.8%) had available data for review. The female to male ratio was 6.2:1. The mean and median ages of onset were 9.7 +/- 2.8 and 10 +/- 2.2 years, respectively (range 4-14 years).

The most common renal, skin and mucocutaneous, and hematological manifestations were proteinuria, malar rash, and anemia, respectively. Lupus nephritis with WHO class IV was the most common histopathological finding of the initial renal biopsies. The most common neuropsychiatric, gastrointestinal, cardiac, and pulmonary involvements were seizure, hepatomegaly, pericarditis, and pleuritis, respectively. Ninety-two percent of patients reported as having significant ANA positive results using rat liver tissue as a substrate. Sixty-six out of 94 patients (70.2%) had positive test result of Anti-dsDNA.
