RESUMO
BACKGROUND: Surgical site infection (SSI) after kidney transplantation can severely compromise graft function and prolong hospital stay. Organ/space SSI (osSSI) is a severe type of SSI associated with a significantly higher mortality rate. AIMS AND OBJECTIVES: This study aims to provide new strategies of managing (osSSI) after kidney transplant and other high-risk wound infections. METHOD: This is a single-center, retrospective study that analyzed the treatment outcomes of 4 patients who developed osSSI after kidney transplant at Shuang-Ho Hospital. The management strategy included real-time fluorescence imaging with MolecuLight, negative-pressure wound therapy (NPWT) with Si-Mesh, and incisional NPWT (iNPWT). RESULT: The average length of hospital stay was 18 days (range, 12-23 days). During hospitalization, all patients obtained high-quality debridement under real-time fluorescence image confirmation. The average duration of NPWT was 11.8 days (range, 7-17 days) and iNPWT was 7 days. All transplanted kidneys were preserved with normal function after 6 months of follow-up. CONCLUSIONS: Our strategies with real-time fluorescence imaging provide a novel and effective method that can be used in adjunct with the standard of care for managing osSSI after kidney transplantation. More studies are warranted to validate the efficacy of our approach.

BACKGROUND: Proteus mirabilis is the second most common pathogen that causes urinary tract infections after Escherichia coli. In rare cases, it is associated with vertebral osteomyelitis. The underlying mechanism of this relationship may be related to the retrograde dissemination of bacteria through the paravertebral venous plexus. CASE PRESENTATION: We report a case of an 80-year-old Taiwanese woman who had recurrent episodes of fever and chronic back pain for 1 year. All blood cultures were positive for P. mirabilis. Inflammation scans and magnetic resonance imaging revealed a previously undetected vertebral lesion between the seventh and eighth thoracic vertebra. She responded well to treatment with antibiotics, reporting considerable relief of back pain and no fever recurrence at the 4-month follow-up. CONCLUSIONS: Chronic back pain is a common but often dismissed symptom among the older population; osteomyelitis should be considered in patients with recurrent fever or neurological symptoms. Old age, chronic renal failure, and diabetes mellitus are possible predisposing factors for osteomyelitis. Our findings suggest that long-term treatment with antibiotics is effective for osteomyelitis caused by P. mirabilis,, although surgery is required for abscess formation or serious vertebral destruction.
