چکیده
TO THE EDITOR—We appreciate the letter by Fabio and Carrabba [1] regarding our article evaluating the performance of the Pneumonia Severity Index (PSI) and CURB-65 (confusion, urea, respiratory rate, blood pressure, age ≥65) scoring systems in predicting 30-day mortality in patients with healthcare-associated pneumonia (HCAP) compared to those with community-acquired pneumonia (CAP) [2]. They evaluated the discriminatory powers of the recently proposed scoring systems, A-DROP (age, dehydration, respiratory failure, orientation disturbance, and low blood pressure) [3] and SOAR (systolic blood pressure, oxygenation, age, and respiratory rate) [4], which were developed to identify the high-mortality-risk patients with CAP, for 30-day mortality in patients with HCAP. In addition, they evaluated the influence of the age variable on the performance of PSI score in predicting 30day mortality in patients with HCAP using the modified PSI excluding the age variable [5]. We also tested these scoring systems retrospectively using our study population. As a result, the estimated areas under the curve (AUC) of A-DROP and SOAR were 0.682 (95% confidence interval [CI], .612–.752) and 0.618 (95% CI, .544–.693), respectively, which were not statistically different from 0.679 (95% CI, .619–.739) of the PSI class in patients with HCAP (P = .922 and P = .067, Hanley-McNeil test). The discriminatory power of modified PSI score

Introduction The inflammasome complex and the inflammatory pathway have been implicated in the pathogenesis of familial Mediterranean fever (FMF), and recently ASC (apoptosis-associated speck-like protein containing a CARD) mRNA expression was found to be up-regulated in patients carrying MEFV mutations independent of the mutation type. Gene-expression profiling has the capacity to reveal trans...
