Acute kidney injury in acute Q fever.

Coxiella burnetii infection is not known to involve directly the kidneys. Kidney injury associated with Q fever usually manifests in the setting of chronic infection or endocarditis with development of immune complex deposition. Acute kidney injury (AKI) in the context of acute Q fever infection may be more pathologically heterogeneous. We describe two cases of severe AKI secondary to acute Q fever infection, each with marked differences in pathological characteristics, and clinical course.
