Abstract

Background

Isolated pulmonary valve infective endocarditis caused by Candida is rare in chronic hemodialysis patients. The 2009 Infectious Diseases Society of America guidelines suggest the combined use of surgery and antibiotics to treat candidiasis; however, successful nonsurgical treatment of Candida endocarditis has been reported.

Case presentation

A 63-year-old woman with end-stage kidney disease was admitted to our hospital after experiencing disorientation for 5 days. The patient was permanently bedridden because of depression, and denied active intravenous drug use. She received maintenance hemodialysis through a tunneled-cuffed catheter. An initial blood culture grew Candida guilliermondii without other bacteria. Subsequent blood cultures and tip culture of tunneled-cuffed catheter also grew C. guilliermondii, even after caspofungin replaced fluconazole. A 1.2-cm mobile mass was observed on the pulmonary valve. Surgical intervention was suggested, but the family of the patient declined because of her multiple comorbidities. The patient was discharged with a prescription of fluconazole, but she died soon after.

Conclusion

Our patient is the first case with isolated pulmonary valve endocarditis caused by C. guilliermondii in patients with uremia. Hematologic disorders, in addition to long-term central venous catheter use, prolonged antibiotic intravenous injection, and congenital cardiac anomaly, predispose to the condition. The diagnosis “isolated” pulmonary IE is difficult, and combing surgery with antifungal antibiotics is the appropriate therapeutic management for Candida related pulmonary IE.
