  ABSTRACT: Systemic-onset JRA is characterized by spiking fevers lasting more than two weeks, typically occurring once, twice each day, with temperature returning to the normal or below normal. There are no specific diagnostic tests for systemic JRA. High level of serum ferritin is the most important, no specific, diagnostic finding associated.
