Pediatric lupus in Asia.
Of all patients with systemic lupus erythematosus (SLE), 15-20% are diagnosed during childhood, with disease onset prior to the age of 16 years. Because disease expression in SLE is influenced by environment factors and differs between racial and ethnic groups. The aims of this review were to describe prevalence, clinical manifestations, common infectious complications, and outcome of pediatric-onset SLE in Asia. The prevalence of pediatric-onset SLE was 6.3-19.3 per 100,000 in Asia. The ratio of female to male was 4.7-6.2. The mean age at diagnosis of pediatric-onset SLE was 8.6-13.5 years. The most common clinical features of pediatric-onset SLE in Asia were cutaneous rashes, arthritis, hematological involvement and nephritis. The occurrence of nephritis varies from 29% to 81%. The most common histopathology of lupus nephritis was diffuse proliferative glomerulonephritis (WHO Class-IV) which occurred in 39.4-54% of case of lupus nephritis. Pediatric-onset SLE patients with infections have poor outcomes than uninfected patients. Gram-negative bacilli are the most common microorganisms responsible for bacteremia in Asian patients with SLE. Recurrent major infections predict poorer disease outcome and associated organ damage in pediatric-onset SLE. Improving the survival of SLE patients was reported in Asia in recent decades. The survival was 92% at the age of 5 years, 86% at 10 years and 79% at 15 years in children with SLE in Taiwan in 2008.
