چکیده
OBJECTIVE Activation of coagulation and inflammation are parts of the innate host response to infection that may contribute to organ dysfunction and death when control of these systems is compromised. Thus, functional single nucleotide polymorphisms within candidate genes of the inflammation and coagulation cascade are possible factors which may influence severity and/or mortality in acute respiratory distress syndrome. The aim of this study was to investigate whether the factor V Leiden mutation (Arg506Gln) is associated with altered severity and/or mortality in acute respiratory distress syndrome. DESIGN Retrospective cohort, genetic association study. SETTING Tertiary care intensive care unit. PATIENTS Adults (white Germans) with acute respiratory distress syndrome (n = 106). INTERVENTIONS Genotyping for the factor V Leiden mutation. MEASUREMENTS AND MAIN RESULTS Using Kaplan-Meier estimates to compare outcome, 30-day survival was significantly associated with the factor V Leiden mutation (p = .049). Thirty-day survival rates were 100% for Arg/Gln (n = 7) genotypes but only 58% for Arg/Arg (n = 99) genotypes, respectively. CONCLUSION We show for the first time that a heterozygous factor V Leiden genotype is associated with improved 30-day survival in patients with acute respiratory distress syndrome.

Background: Factor V Leiden, Prothrombin gene (G20210A) and MTHFR (C677T) polymorphism are the main biomarkers for evaluation of tendency for venous thromboembolism. We aimed to investigate the frequency of mutations in factor V Leiden, Prothrombin G20210A and MTHFR C677T and identify the genetic status for these mutations in patients with venous thrombosis. Methods: This study was carried out...

Acute Respiratory Distress Syndrome (ARDS) is a clinical syndrome consisting of tachypnea, refractory hypoxemia, and diffuse opacities on chest radiographs after infection or trauma which ultimately leads to respiratory failure. The principles of treatment are based on patient care in ICU, mechanical ventilation and medical treatments. By using lower plateau, less tidal volume, higher positive ...
