Hematogenous pleural infection caused by Achromobacter xylosoxidans in a patient undergoing maintenance hemodialysis.

A 78-year-old Japanese man, undergoing maintenance hemodialysis for 20 years and having received coronary artery bypass grafting two months before, was hospitalized because of fever with subclinical left-sided pleurisy. Achromobacter xylosoxidans strains exhibiting identical genomic patterns on a macrorestriction analysis were isolated from the blood and the pleural effusion obtained on admission. Physical and radiological examinations did not reveal any lesions in either chest wall or lung adjacent to the effusion, indicating that the organism in the effusion had entered the pleural space via the bloodstream. Immunocompromising conditions due to undergoing maintenance hemodialysis and the presence of the antecedently accumulated pleural effusion may have been associated with the development of hematogenous dissemination. The patient fully recovered only with antibiotic therapy. To our knowledge, the present report is the first describing a case of hematogenous pleural infection caused by A. xylosoxidans.
