Systemic lupus erythematosus in childhood

Area of Science:

• Pediatric Rheumatology
• Immunology
• Clinical Medicine

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect various organs.
• Understanding the long-term prognosis of childhood-onset SLE is crucial for patient management and counseling.

Purpose of the Study:

• To retrospectively analyze the clinical and serological features of pediatric SLE patients.
• To evaluate the survival rates and prognostic factors in childhood-onset SLE.
• To compare clinical and serological findings across different age groups (prepubertal, adolescent, adult).

Main Methods:

• Retrospective analysis of clinical and serological data from 42 patients with SLE onset before age 16.
• Calculation of survival rates from both date of onset and date of diagnosis.
• Stratification of survival analysis based on the presence of lupus nephritis.

Main Results:

• The study included 37 females and 5 males, with a mean age of onset of 12.3 years.
• Overall 5-year and 10-year survival rates from diagnosis were 82.6% and 76.1%, respectively.
• Survival rates for patients with lupus nephritis were significantly lower: 59.5% at 5 years and 47.6% at 10 years.
• No major differences in clinical or serological findings were observed between prepubertal, adolescent, and adult SLE.

Conclusions:

• Childhood-onset SLE does not necessarily portend a poor prognosis, with a considerable proportion of patients surviving long-term.
• Lupus nephritis remains a significant predictor of poorer survival in pediatric SLE patients.
• Clinical and serological manifestations of SLE appear consistent across different age groups from childhood through adulthood.
