Prosthetic valve endocarditis caused by Acinetobacter lwoffi: a case report and review.

Author information

Department of Internal Medicine, Patras University Hospital, Patras, Greece.


We are reporting a case of recurrent prosthetic-valve endocarditis (PVE) caused by an unusual pathogen. The patient suffered 2 consecutive relapses of Acinetobacter lwoffi bacteremia, although he had completed a full course of treatment with antibiotics to which the microorganism was susceptible. He was finally successfully operated with replacement of the infected aortic valve. Acinetobacter spp are relatively low-grade but potentially virulent pathogens, and endocarditis caused by these species can be fulminant, accompanied by septic complications, and fatal. Although some patients with relapsed PVE may respond to a second course of antibiotics and medical treatment rather than early valve replacement is suggested in A lwoffi PVE, combined antibiotic treatment and early surgical intervention may be considered as the first option in these patients. There are only a few cases of Acinetobacter endocarditis in the literature, and it is the first case reported in Greece to our knowledge.
