Abstract

Shewanella putrefaciens is a common cause of skin and soft tissue infections but is rarely seen as a cause of pneumonia. Here we report a case of S. putrefaciens pneumonia complicated by bacteremia in a patient with cardiogenic pulmonary oedema. A 66-year-old woman was admitted to the emergency department with complaints of dyspnoea and fever. The patient was orotracheally intubated and a chest computed tomography showedshowed bilateral diffuse central and peripheral ground-glass opacities and a bilateral pleural effusion 20 mm wide. Cardiogenic pulmonary oedema was considered in the patient due to her chronic ischaemic heart disease and bilateral 2+ pretibial oedema. However, pneumonia associated with pulmonary oedema was considered in a patient with high fever, neutrophilic leucocytosis and a C-reactive protein of 18 mg/L. Moxifloxacin 1x400 mg intravenously was started empirically. Gram-negative bacilli grown in blood culture were identified as S. putrefaciens. Antimicrobial susceptibility testing demonstrated no resistance. The patient was discharged with complete recovery after 14 days of antibiotherapy.

Özet

Shewanella putrefaciens deri ve yumuşak doku enfeksiyonlarına daha sık neden olurken nadiren pnömoni etkeni olarak görülür. Burada kardiyojenik akciğer ödemi tablosu ile acil servise getirilen ve bakteriyemi komplikasyonu gelişmiş olan bir S. putrefaciens pnömonisi sunulmaktadır. 66 yaşında kadın hasta, acil servise nefes darlığı ve ateş şikayetleri ile başvurmuştur. Orotrakeal entübe edilen hastanın akciğer tomografisinde bilateral diffüz santral ve periferal buzlu cam dansitesinde infiltrasyon alanları ve her iki tarafta en geniş yeri 20 mm plevral effüzyon görüldü. Kronik iskemik kalp hastalığı olan ve bilateral 2+ pretibial ödemi olan hastada kardiyojenik akciğer ödemi düşünüldü. Ancak ateş yüksekliği ve nötrofilik lökositozu olan ve C-reaktif proteini 18 mg/L olan hastada akciğer ödemine eşlik eden bir pnömoni düşünüldü. Hastaya ampirik olarak intravenöz moksifloksasin 1x400 mg başlandı. Kan kültüründe üreyen Gram negatif basil S. putrefaciens olarak tanımlandı. Antibiyotik duyarlılık testinde herhangi bir direnç saptanmadı. Hasta antibiyoterapisi 14 güne tamamlanarak tam şifa ile taburcu edildi.
