RESUMO
PURPOSE: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. METHODS: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65â¯years,65 to 80â¯years,andâ¯≥â¯80â¯years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. RESULTS: A total of 3120 patients with IE (1327â¯<â¯65â¯years;1291 65-80â¯years;502â¯≥â¯80â¯years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80â¯years who underwent surgery were significantly lower compared with other age groups (14.3%,65â¯years; 20.5%,65-79â¯years; 31.3%,≥80â¯years). In-hospital mortality was lower in the <65-year group (20.3%,<65â¯years;30.1%,65-79â¯years;34.7%,≥80â¯years;pâ¯<â¯0.001) as well as 1-year mortality (3.2%, <65â¯years; 5.5%, 65-80â¯years;7.6%,≥80â¯years; pâ¯=â¯0.003).Independent predictors of mortality were ageâ¯≥â¯80â¯years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32-3.34), CCIâ¯≥â¯3 (HR:1.62; 95% CI:1.39-1.88),and non-performed surgery (HR:1.64;95% CI:11.16-1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65â¯years(pâ¯<â¯0.001) for both in-hospital and 1-year mortality. CONCLUSION: There were no differences in the clinical presentation of IE between the groups. Ageâ¯≥â¯80â¯years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group.

INTRODUCTION: Two tests for the detection of antibodies to Candida albicans germ tubes in patients with invasive candidiasis were compared: a new commercially available test (Candida albicans IFA IgG) and the indirect immunofluorescence test generally used for this purpose. METHODS: With the use of two indirect immunofluorescence tests, retrospective study was done on 172 sera from 51 patients classified into two groups: Group I included 123 serum samples from 32 patients with invasive candidiasis, and Group II, the control, included 49 serum samples from 19 patients with no evidence of Candida infection. RESULTS: In Group I, 84% of patients presented anti-germ tube antibody titers >or= 1:160 by the Candida albicans IFA IgG test and 78.1% of patients were positive by the generally used test. There was a high correlation between the two tests (R2 =0.9512 by patients; R2 = 0.8986 by sera). When a titer value of >or= 1:160 was used as cutoff, the Candida albicans IFA IgG test showed a sensitivity of 84.4% and a specificity of 94.7%, whereas the traditional test showed a sensitivity of 78.1% and a specificity of 100%. CONCLUSIONS: The commercially available Candida albicans IFA IgG test is similar to the test generally used for the detection of antibodies to C. albicans germ tubes and provides faster and easier diagnosis of invasive candidiasis in the clinical microbiology laboratory.
