Campylobacter fetus subsp. fetus bacteremia in a patient with myelodysplastic syndrome: A case report

Abstract

Campylobacter fetus is an important pathogen of extra intestinal infections in patients with immunodeficiency. A case of Campylobacter fetus subsp. fetus bacteremia in a patient with myelodysplastic syndrome was presented in this study. A 78-year-old woman with myelodysplastic syndrome was admitted to the emergency due to chest pain and dyspnea. A diagnosis of pneumonia was made, and blood, throat, and urine samples were obtained for microbiological tests. Trimethoprim-sulfamethoxazole and piperacillin-tazobactam were empirically initiated. C. fetus subsp. fetus was isolated from blood cultures and clarithromycin was added. The patient responded an overall 21-day antimicrobial treatment. Because repeated blood cultures were negative, and her general condition improved, upon that she was discharged from the hospital. In conclusion, the incidence of C. fetus infections was low, and case reports are rare in current literature in Turkey. The infections can occur with these bacteria should not be overlooked in the clinical laboratory.

Öz

Campylobacter fetus immün yetmezliği olan hastalarda bağırsak dışı enfeksiyonların önemli bir etkenidir. Bu çalışmada miyelodisplastik sendromlu bir hastada C. fetus subsp. fetus’e bağlı bir bakteriyemi olgusu sunuldu. Miyelodisplastik sendrom tanısı olan 78 yaşında kadın hasta, solunum sıkıntısı ve göğüs ağrısı şikayeti ile acile kabul edildi. Hastaya pnömoni tanısı konuldu ve mikrobiyolojik testler için kan, boğaz ve idrar örnekleri alındı. Ampirik olarak trimetoprim-sulfametaksazol ve piperasilin-tazobaktam başlandı. Kan kültürlerinden C. fetus subsp. fetus izole edildi ve tedaviye klaritromisin eklendi. Hasta toplam 21 gün antibiyotik tedavisi aldı. Genel durumu düzelen hasta tekrarlayan kan kültürlerinde üreme olmaması üzerine taburcu edildi.Türkiye’de mevcut literatürde C. fetus enfeksiyonlarının insidansı düşüktür ve olgu raporları nadirdir. Bu bakteri ile oluşabilecek enfeksiyonlar klinik laboratuvarlarda göz ardı edilmemelidir
