Major infections in a cohort of 120 patients with juvenile-onset systemic lupus erythematosus.

Abstract In order to describe the incidence and characteristics of major infections in juvenile-onset systemic lupus erythematosus (jSLE), we studied a cohort of 120 patients (51% Hispanic and 28% African American, 49% with renal involvement and 12% with neuropsychiatric manifestations).
