Background: Systemic lupus erythematosus (SLE) is a complex autoimmune disease that occurs worldwide in both children and adults, with different disease manifestations, activity and severity between them. Objectives: To analyse the difference in disease onset patterns and activity in Egyptian children and adults with SLE. Methods: A retrospective cohort study conducted on 298 Egyptian SLE patients, 215 adults (a-SLE) (>18 years) and 83 children (j-SLE) (<= 18 years). Disease onset, clinical manifestations and laboratory investigations were recorded. The systemic lupus erythematosus disease activity index (SLEDAI) was used to assess disease onset activity; renal biopsy was performed for all cases affected with renal symptoms. Results: A total of 215 a-SLE (F/M: 14.4/1), mean age 29.65 +/- 10.235 years, and 83 j-SLE (F/M: 5.4/1), mean age at diagnosis 12.63 +/- 3.112 years. The most frequent initial a-SLE symptoms were constitutional (88.8%), mucocutaneous (71.2%), haematological (64.2%), articular (62.3%), renal (43.7%), vascular (15.3%), serositis (14.4%) and finally central nervous system (11.6%). There were no significant differences between a-SLE and j-SLE with regard to constitutional, mucocutaneous, renal, vascular and serositis manifestations, which were 92.8%, 74.7%, 53%, 16.9% and 10.8%, respectively, but the j-SLE haematological (88%) and central nervous system (30.1%) manifestations were significantly higher than a-SLE and articular manifestations were significantly lower in j-SLE (14.5%) than a-SLE. Antinuclear antibodies were positive for 95.3% of a-SLE and 97.6% of j-SLE. Anti-dsDNA was positive for 84.7% a-SLE and was significantly higher in j-SLE (92.8%). The SLEDAI score was 12.23 +/- 4.966 in a-SLE and was significantly higher in j-SLE (27.13 +/- 19.968). International Society of Nephrology lupus nephritis classes III and IV (42.4%) were the commonest findings in a-SLE; however, classes I and III (57.9%) were the commonest in j-SLE. Conclusions: SLE had a wide variety of clinical and immunological manifestations, with some similarity and differences between a-SLE and j-SLE; juvenile onset lupus had a higher SLEDAI with more aggressive initial manifestations than a-SLE.
