RESUMO
BACKGROUND: We wanted to investigate the effect of infectious complications on the outcome of patients who received allogeneic hematopoietic stem cell transplantation (HSCT), and we determined the risk factors for predicting infectious complication and the mortality in allogeneic HSCT recipients. METHODS: We enrolled all the patients who underwent allogeneic HSCT at Samsung Medical Center from February 1996 to October 2003. RESULTS: A total of 139 patients were enrolled. A total of 450 infectious episodes were observed in 131 allogeneic recipients (90.8%). Infectious complications occurred in the allogeneic recipients [3.243.00 episodes/patient]. Microbiologically documented infection (MDI), clinically documented infection (CDI), and unknown fever (UF) accounted for 41.6%, 34.0% and 24.4%, respectively, of the total infections. Pneumonia (15.1%) was the most common infection. Among the 187 MDIs, bacterial infection, viral infection and fungal infection accounted for 50.3%, 39.6%, and 7.5%, respectively. Twelve of 24 deaths in the late post-transplantation period were related with infection. The statistically significant risk factors for infection related to mortality, by multivariate analysis, were the underlying disease risk, the duration of neutropenia, the failure of stem cell engraftment, acute GVHD, MDI, UF, the number of infectious episodes, bacteremia, fungemia, pneumonia, genitourinary tract infections, S. aureus, E. coli, Pseudomonas spp., Aspergillus spp., Non-albicans candida and CMV diseases. CONCLUSIONS: The incidence of fungal infections was still low in our institute, even though prophylaxis for fungal infections was not applied, except for gargling with nystatin. In addition, most of them were non-albican Candida and Aspergillus species. Therefore, routine fluconazole prophylaxis may not be needed in our institute.

Pneumonia and meningitis are the most frequent manifestations of pneumococcal infections. Pneumococcal spinal epidural abscesses have been rarely reported. Spinal epidural abscess by Streptococcus pneumoniae has been diagnosed among the patients with diabetes mellitus, alcoholism, corticosteroid therapy, intravenous drug use, chronic renal failure, AIDS, and history of spinal surgery. Recently, we experienced a case of pneumococcal spinal epidural abscess after spinal trauma. A 36-year-old male patient was admitted with back pain, fever, and paraplegia which occurred 5 days after the trauma. Spine MRI revealed spinal epidural abscess at the level from T2 to T9. He was treated with antimicrobial agents and surgical exploration for spinal epidural abscess. Pus culture grew S. pneumoniae which was susceptible to penicillin. Despite early surgical treatment, neurologic sequelae remained. Considering the high mortality and morbidity of pneumococcal spinal epidural abscess, early diagnosis and aggressive treatment including surgical intervention and antibiotics therapy should be implemented immediately.
