Persistent Legionnaire's disease in an adult with hairy cell leukemia successfully treated with prolonged levofloxacin therapy
Abstract
Legionnaire's disease (LD) manifests most commonly as an atypical community acquired pneumonia (CAP) with systemic extrapulmonary manifestations. Disorders associated with impaired cell mediated immunity (CMI) are particularly predisposed to LD. Hairy cell leukemia (HCL) is a rare B-cell lymphoproliferative leukemia associated with decreased CMI. LD has only rarely been reported in HCL. We present a most interesting case of persistent LD in a elderly male with HCL who required prolonged antibiotic therapy.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
