ObjectiveTo evaluate the incidence of urinary tract infections due to Trichosporon spp. in an intensive care unit.MethodsThis descriptive observational study was conducted in an intensive care unit between 2007 and 2009. All consecutive patients admitted to the intensive care unit with a confirmed diagnosis were evaluated.ResultsTwenty patients presented with urinary tract infections due to Trichosporon spp. The prevalence was higher among men (65%) and among individuals > 70 years of age (55%). The mortality rate was 20%. The average intensive care unit stay was 19.8 days. The onset of infection was associated with prior use of antibiotics and was more frequent in the fall and winter.ConclusionInfection due to Trichosporon spp. was more common in men and among those > 70 years of age and was associated with the use of an indwelling urinary catheter for more than 20 days and with the use of broadspectrum antibiotics for more than 14 days. In addition, patients with urinary infection due to Trichosporon spp. were most often hospitalized in intensive care units in the fall and winter periods.

“…A partir da década de 1980, constatou-se a emergência de infecções fúngicas nosocomiais causadas principalmente por leveduras do gênero Candida, representando um sério problema de saúde. 1,2 As leveduras do gênero Candida são consideradas os terceiros agentes etiológicos comumente observados em casos de sepses em centros de terapias intensivas. O aumento do número de pacientes imunocomprometidos, principalmente portadores do vírus HIV e a o aumento da resistência aos antifúngicos disponíveis são os principais responsáveis pela elevada prevalência desta infecção.…”

Rev. Virtual Quim. |Vol 7| |No. 6| |2113-2123| 2113 Artigo Síntese, Toxicidade e Atividade da Carboximetilquitosana na Formação de Biofilme por Candida sp. Ribeiro, C. L.; Bukzen, A. L.; Ribeiro, E. L.; Silva, M. R. R.; Signini, R.; Naves, P. L. F.* Rev. Virtual Quim., 2015, 7 (6), 2113-2123. Data de publicação na Web: 3 de outubro de 2015Abstract: Increasing incidence of infections caused by Candida sp. and its resistance to antifungals justify the research of novel compounds with antimicrobial activity. Carboxymethylchitosan is a derivative of chitosan with properties such as biocompatibility, biodegradability and solubility in a wide range of pH and for these reasons is interested in medical and pharmaceutical areas. In this study, carboxymethylchitosan was obtained by carboxymethylation of chitosan and then purified and characterized by analysis of solubility degree, solubility at different pH ranges and infrared spectroscopy. The toxicity of the compound was determined by brine shrimp lethality assay, and its activity was subsequently evaluated in biofilm formation by Candida yeasts. The results showed an initial weight gain, after purification, a loss of the total weight of the polymer, the degree of substitution was influenced by the reaction conditions and the reaction time, the compound was soluble in a wide pH range including groups acid-neutral-base. It was found that the carboxymethylchitosan was non-toxic against Artemia salina in the evaluated concentrations and showed no significant inhibitory activity against biofilm formation by Candida sp. The lack of toxicity increases the prospect of further applications of the compound, for example, as a carrier and a complexing agent with proven antifungal compounds.
