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: Evaluate the nutritional status of patients with cardiac disease and concomitant renal dysfunction requiring renal replacement therapy. METHODS: Patients with cardiac disease and renal failure receiving renal replacement therapy, admitted to an intensive care unit, were submitted to nutritional evaluation, by use of anthropometric measurements and laboratory data. RESULTS: We studied 43 patients, mean age 64±15 years, 26 were men. The mean left ventricular ejection fraction was 0.36±0.16. Analysis of anthropometric measurements, based on body mass index disclosed that, 18 patients were normal, 6 were underweight and 19 were overweight or obese. Based on measurement of triceps skinfold thickness, 16 patients were considered normal and 27 had some degree of depletion. Measurements of midarm circumference and midarm muscular circumference showed 41 patients with some degree of depletion. Laboratory data revealed 28 patients with depletion based on albumin levels and 27 with depletion based on lymphocyte count. CONCLUSIONS: Malnutrition is common in critically ill patients with cardiac disease and renal failure receiving renal replacement therapy. Nutritional assessment based on body mass index did not prove to be a good index for diagnosis of nutritional disorders. The nutritional evaluation must be complemented in order to identify malnutrition and introduce early nutritional support.

BACKGROUND AND OBJECTIVES: Use of low molecular weight heparins (LMWH), either prophylactic or therapeutic, is of most importance in several syndromes and diseases in daily clinical practice. Our objective in this clinical trial was to evaluate safety and efficacy of test sodium enoxaparin (ENOX-T) compared to the reference drug (ENOX-R). METHODS: We conducted a prospective, randomized, comparative, unicentric and open-labeled trial including patients with either prophylactic or therapeutic anti-thrombotic indications. A total of 100 patients were enrolled in two branches: prophylactic (n=50) and therapeutic (n=50) and two groups for each branch (group 1: ENOX-R and group 2: ENOX-T). We analyzed clinical and laboratory data in each segment. Anti-factor Xa was measured in three different moments: baseline (1st evaluation); 1st or 2nd day (2nd evaluation) and 5th to 7th day (3rd evaluation). Doppler-sonography of inferior limbs was performed on all patients in prophylactic group on 2nd or 3rd evaluation. RESULTS: The data showed that both branches (prophylactic and therapeutic) were homogenous in regard of sex, age, body mass index (BMI), serum creatinine and APACHE II severity score at admission. Anti-factor Xa results, in both prophylactic and therapeutic branches, showed expected efficacy to both drugs, without any clinical or statistical difference between them. Adverse events incurred in both groups in a similar way, without any clinical or statistical difference between them. In prophylactic branch, Doppler-sonography of inferior limbs added useful information on drugs efficacy. CONCLUSIONS: We conclude that test sodium enoxaparin (ENOX-T) was effective and safe in our patient's cohort and equivalent to reference drug (ENOX-R).
