Introduction:
Only a few cases of K. kristinae infection have been reported in the literature. Patients with short bowel syndrome have an increased risk of opportunistic infections due to decreased bowel immunity and the long-term central venous catheter placement. We report a rare case of K. kristinae infection associated with SBS requiring long-term central venous access port placement.
Presentation of case:
A 70-year-old woman presented with fever of approximately 39 °C to our hospital for examination. She has undergone total hysterectomy and radiation therapy for cervical cancer 36 years ago. Five years ago, she developed multiple small bowel perforations, and a jejunostomy was constructed at the oral end of the perforation and approximately 110 cm from the ligament of Treitz because of the difficulty in dissecting the adhesion. She developed short bowel syndrome, and the central venous port was constructed four years ago due to poor enteral nutrition. K. kristinae was detected in the central venous catheter tip and in two blood cultures. We administered intravenous vancomycin. After seven days of antibiotic treatment, both fever and inflammatory reaction improved, and the blood culture was negative. After 16 days of antibiotic treatment, we performed central venous port construction on the side opposite to the previous site.
Conclusion:
Patients with short bowel syndrome have an increased risk of K. kristinae infections due to decreased bowel immunity and the long-term central venous port, and therefore, these patients should be followed up carefully.
