BACKGROUND AND OBJECTIVES: Infection with the non-Candida yeast species Trichosporon have been recognized with increasing frequency over the last two decades. Invasive disease due to trichosporonosis has been reported from neutropenic patients with cancer and the mortality is high. Recently, others groups of patients have become susceptible to this rare fungi. We report the emerging of infection with pathogenic Trichosporon asahii in severely ill heart failure patients in a tertiary cardiological intensive care unit (CICU). We describe our data, and report a fatal case of disseminated trichosporonosis in a patient with heart failure. We also review literature pertaining to T. asahii infections. CASE REPORT: An 85 year-old woman with a history of hypertension, heart failure (ejection fraction (EJ): 30%) and pulmonary embolism was admitted to a medical cardiological ICU after cardiac arrest (ventricular fibrillation) resuscitated during a routine consultation. There were no neurological sequelae and the echocardiogram revels no changes, neither the cardiac biomarkers. Ventricular fibrillation was considered secondary to heart failure. The patient had extubation failure and difficult weaning needing long term mechanical ventilation even after tracheostomy. Her hospital course was complicated by acute renal failure and recurrent respiratory, urinary and systemic bacterial infections, which responded to broad-spectrum antibiotics. After a temporary improvement she developed urinary infection and subsequent septic shock. Cultures of urine and blood specimens grew T. asahii. Treatment with liposome amphotericin B (5 mg/kg/day) was started. Despite receiving vancomycin and imipenem, the clinical condition of the patient deteriorates. Blood taken for culture on the seventh day of amphotericin B therapy were negative but urine specimen still grew T. asahii. On the eighteenth day of antifungal therapy, the patient died with multiorgan failure. CONCLUSIONS: The increasing of severely ill patients, and the use of broad spectrum antibiotics, has predisposed the emerging of invasive infections by rare and new opportunistic fungal pathogens. Severe infection related to T. asahii, until recently restricted to neutropenic patients with cancer, has been frequently identified in heart failure patients with advanced age. The mortality is high. These data highlights the importance of considering this group of patients as a risk group for T. asahii infection.

OBJECTIVE: Infection is one of the main complications of dialysis procedures to correct renal injury, with a significant impact on morbidity mortality in chronic and critically acute dialysis patients. The objective of this work was to review literature on infection in patients submitted to hemodyalisis. METHODS: A survey of publications from 1990 to March 2008 was carried out in the database COCHRANE, PubMed/MEDLINE, Latin-American and Caribbean literature on Health Sciences and Nursing database. In Health Science (DECS) and Medical Subject Headings Section (MeSH) from |PubMed/MEDLINE the following descriptors were used: infection; cross infection; bacteremia; renal dialysis; renal failure;acute renal failure; hemofiltation; hemodiafiltration; renal replacement therapy. RESULTS: Thirty three articles were selected. Most publications were American, from 2001 to 2005 and mainly about vascular access-related infection. Studies diverged on the definition of infection and nomenclature, hindering comparisons. Fiver articles covered different infection topographies, 16 studied vascular access-related infections in the different types of vascular accesses, nine specifically focused on temporary central catheters for hemodialysis and only three studied infections in intensive care unit patients. Temporary central catheters for hemodialysis were identified as the principal risk factor. CONCLUSION: There is a need for studies about infection incidence in critically ill, submitted to dialysis with temporary catheters, due to acute renal injury to define a causal relationship and risk factors to orient adequate prevention and control measures.
