Abstract
PURPOSE OF REVIEW: The non-specific presentation of acute Q fever makes it difficult to diagnose in children, but untreated Q fever can result in chronic infections that have severe complications. RECENT FINDINGS: Pediatric Q fever cases continue to be infrequently reported in the literature, and primarily document cases of persistent infections with Coxiella burnetii. Standardized treatment protocols for chronic Q fever in children still do not exist. Doxycycline and hydroxychloroquine are the treatment combination most utilized by healthcare providers to treat Q fever endocarditis or osteomyelitis in children, but a variety of other antibiotic combinations have been reported with varying results. The use of adjunctive therapies, such as such as interferon gamma, has produced mixed outcomes. SUMMARY: The true impact of Coxiella burnetii on the health of children remains unknown; long-term longitudinal follow-up of children with acute or chronic Q fever has not been reported. Both the acute and chronic forms of Q fever are underreported and underdiagnosed. Healthcare providers should consider Q fever in pediatric patients with culture-negative endocarditis or osteomyelitis.
