To the Editors,
Yersinia enterocolitica is a gram-negative bacillus of the Enterobacteriacea family. Spread of infection from source to humans may occur via contaminated water or food or directly from a blood transfusion. Resulting infection can range from gastroenteritis to septicemia, including metastatic infection [1].
An 85-year-old man with history of end-stage renal disease (with a tuneled catheter as vascular access), prostate cancer, and diabetes mellitus, was referred to the emergency department (ED) after a hemodialysis session due to hemoglobin (Hb) value 6.7 g/dL. He did a unit of red blood concentration (RBC) and was discharged. A few hours later he was malaise and febrile, but went to the ED only five days later. At admission, he was febrile (39.6°C) and hypotensive (94–47 mmHg). Laboratory results identified Hb 7.6 g/dL; leukocytes 13,200/ul, neutrophils 86.6%, C-reactive protein (CRP) 28 mg/dL, normal urinary sediment, and no alteration on chest X-ray. As the patient did not have any apparent source of infection, it was assumed a catheter-related infection. It was removed and initiated vancomycin and gentamicin.
On the fifth day of antibiotic, Y. enterocolitica was identified at the catheter and on peripheral blood cultures. We interrupted vancomycin and started ciprofloxacin according to the antibiotic sensitivity test.
The case was reported to the blood service, this is performed whenever there is a suspected complication. The RBC donor was called and the study showed the presence of high titters (200) of anti-Yersinia antibodies from the same isolate strain measured by indirect immunofluorescence. The patient completed 21 days of antibiotic therapy with good clinical evolution. It is a case of post-transfusional bacterial sepsis that had a favorable outcome, unlike most cases described in the literature. Due to its psychotropic action, Y. enterocolitica is not inhibited by the storage temperatures off blood (2–6°C) [2]. Bacterial multiplication is supported both for glucose and adenine of the anticoagulant preparative and additive solution and by the hemoglobin and iron resulting from cell lysis over the shelf life [3].
Systematic screening of blood donations for the presence of blood-borne viruses has resulted in an important decrease of viral infections [4], and bacterial sepsis has become the most frequent infectious complication of transfusion in developed countries [5].
Yersinia enterocolitica is associated with ~46% of documented cases of clinical sepsis from a contaminated RBC; nevertheless, this is an infrequent event. The screening of Yersinia infection in red blood cell units is the only way to avoid the blood donor transmission. Unfortunately it is too expensive, thus not cost effective, so it is up to the clinician to avoid transfusions and decrease the risk.
