Chronic granulomatous disease (CGD) presenting as quotidian fever
Pediatric Rheumatology volume 6, Article number: P203 (2008)
Quotidian fever of unknown origin involves a broad differential diagnosis and challenges therapeutic decision making. We identified CGD in a five year old Turkish boy with systemic inflammation mimicking systemic onset JIA (SOJIA).
The patient presented with 7 days of spiking fever not responding to oral antibiotics, arthralgias and a maculous rash. Laboratory results showed leukocytosis, thrombocytosis, CrP of 240 mg/l, ESR 100 mm. The symptoms persisted under intravenous antibiotic treatment. Focus work-up gave no evidence of an infectious origin, malignancy, IBD, vasculitis, connective tissue disease or periodic fever syndrome. Due to suspicion of incomplete SOJIA a steroid pulse was given. Disease activity responded promptly, consequently methotrexate was added.
After steroid reduction fever and arthralgias recurred and inflammation increased. Physical and radiological examinations and echocardiography were normal. Another steroid pulse was successful and Ciclosporine was added. Again systemic inflammation appeared with decreasing steroids. Thorax x-ray showed interstitial infiltrates. CT identified a ground-glass pattern, a circular pleural lesion and a small hypodense hepatic lesion. Those two abscesses led us to perform granulocyte function tests: Dihydrorhodamine-testing showed absent NADPH-oxidase activity. Aspergillus fumigatus was cultivated following pulmonary lavage.
The child responded well to antibiotic and anti-fungal treatment. Stem cell transplantation is being discussed as a curative treatment.
SOJIA as one cause of systemic inflammation is an exclusion disorder. The incidental finding of abscesses in our case led to CGD. This emphasizes the need for repeated diagnostic approaches in patients with unexplained fever attacks.
