Acute respiratory failure revealing adult-onset Still's disease. Diagnostic value of low glycosylated ferritin level

Abstract

The authors report three cases of adult-onset Still's disease with severe hypoxemic pulmonary involvement, mimicking severe pulmonary sepsis. Clinicians must be aware of this rare form of such disease. Low (<20%) glycosylated ferritin level in the presence of unexplained prolonged fever with leukocytosis can help in the diagnosis. © Clinical Rheumatology 2006.
