Candida esophagitis: species distribution and risk factors for infection Esofagite por Candida: distribuição da espécie e fatores de risco para a infecção
Although Candida albicans is the main cause of fungal esophagitis, other species such as C. tropicalis, C. krusei and C. stellatoidea have also been implicated. Several studies have identified risk factors for C. albicans esophagitis. However, data for non-C. albicans species is still sparse. The aim of this study was to determine the etiology of Candida esophagitis in our medical centre over an 18-month period. Additionally, we aimed to investigate predisposing conditions for esophageal candidosis caused by different Candida species. A total of 21,248 upper gastroscopies were performed in Santa Casa Complexo Hospitalar between January 2005 and July 2006. The prevalence of Candida esophagitis was 0.74% (n = 158). C. albicans caused the vast majority of infections (96.2%), followed by C. tropicalis (2.5%), C. lusitaniae (0.6%) and C. glabrata (0.6%). There were 81 women (51.3%) and 77 men (48.7%). No case of mixed infection occurred. Concomitant oral candidosis was documented for 10.8% (n = 17). Most of cases (55.1%) involved outpatients. Around one fifth of patients in our cohort had no identifiable risk factors for esophageal candidosis (20.8%). Since nearly all infections were caused by C. albicans we were not able to determine risk factors for esophagitis caused by other Candida species.<br>Embora Candida albicans seja a principal causa de esofagite fúngica, outras espécies como C. tropicalis, C. krusei e C. stellatoidea também têm sido implicadas. O objetivo desse estudo foi descrever espécies causadoras de esofagite fúngica em nosso centro durante um perÃodo de 18 meses, além de comparar condições predisponentes para candidose esofágica causadas por diferentes espécies de Candida. De janeiro de 2005 a julho de 2006, 21.248 endoscopias digestivas altas foram realizadas no Complexo Hospitalar Santa Casa (Porto Alegre, Brasil). A prevalência de esofagite por Candida foi de 0,74% (n = 158). C. albicans foi a causadora da maioria das infecções (96,2%), seguida por C. tropicalis (2,5%), C. lusitaniae (0,6%) e C. glabrata (0,6%). Candidose oral concomitante foi documentada em 10,8% (n = 17). Cerca de 21% dos pacientes não teve qualquer fator de risco identificável para candidose esofágica. Em função do pequeno número de pacientes infectados por espécies não-Candida albicans, não foi possÃvel determinarmos fatores de risco para estas infecções

Cardiovascular events associated with rofecoxib : final analysis of the APPROVe trial
Background: Selective inhibition of cyclo-oxygenase-2 has been associated with an increased risk of cardiovascular events in several clinical trials. The Adenomatous Polyp Prevention on Vioxx (APPROVe) study assessed the effect of 3-year treatment with a cyclo-oxygenase-2 inhibitor, rofecoxib (25 mg), on recurrence of neoplastic polyps of the large bowel. We report the cardiovascular outcomes of a long-term follow-up of participants in the trial. Methods: The APPROVe study is a multicentre, randomised, placebo-controlled, double-blind trial. 2587 patients with a history of colorectal adenomas were recruited at 108 centres worldwide during 2000 and 2001. Participants were followed for adverse events while on treatment and during the following 14 days. However, after early termination of treatment because of cardiovascular toxicity, we attempted to follow up all randomised patients for at least 1 year after stopping study treatment. External committees blindly assessed potential serious cardiovascular events. The focus of the analysis was the combined incidence of non-fatal myocardial infarction, non-fatal stroke, and death from cardiovascular, haemorrhagic, and unknown causes (Antiplatelet Trialists' Collaboration [APTC] combined endpoint). We used Cox proportional hazards regression to calculate endpoint hazard ratios. The study is registered with ClinicalTrials.gov, number NCT0282386. Findings: We obtained extended post-treatment cardiovascular follow-up data from 84% of participants, and extended mortality follow-up from 95%. In total, 59 individuals had an APTC endpoint in the rofecoxib group and 34 in the placebo group (hazard ratio 1.79, 95% CI 1.17-2.73; p=0.006). In the first year after cessation of treatment, there was a non-significant increase in the risks of APTC endpoints. The APTC hazard ratio did not substantially change over time. Interpretation: Use of rofecoxib is associated with increased rates of APTC events. Study data are compatible with an early increase in risk that persists for one year after stopping treatment
