Non-invasive ventilation as a first-line treatment for acute respiratory failure: "real life" experience in the emergency department

Objective: To describe our experience with non-invasive ventilation (NIV) for patients with acute respiratory failure (ARF) in the emergency department (ED). Methods: A prospective/retrospective, observational study on 190 patients with ARF (mean ±SD age 72.2±12.9 years, mean APACHE II score 18.9±5.9), who received 200 NIV trials in an ED. We analysed the NIV register data (prospectively collected) and medical records (retrospective data abstraction) and evaluated clinical indications for NIV, patient outcomes, and predictive factors for success and death. NIV success was defined as tolerance of the procedure and no need for endotracheal intubation (ETI). Results: Main indications to NIV were cardiogenic pulmonary oedema (CPE) (70 trials), acute exacerbation of COPD (39), both CPE and acute exacerbation of COPD (11), pneumonia (48), decompensation of obesity/hypoventilation (6), other conditions (26). The procedure was successful in 60.5% of trials. Global mortality was 34.5%, similar to the APACHE II predicted mortality of 32%. ETI rates were 6.5% and tracheostomy rates 1%. The improvement of pH within six hours after NIV initiation was predictive of survival in the hypercapnic group. Conclusions: Our results confirm the global efficacy of NIV in an ED setting, and show that, in spite of lower success rate in "real practice" in comparison with RCTs, an intermediate care unit can represent an appropriate and less expensive setting to perform this technique. The low rate of ETI seems to be because of the high number of patients for whom NIV was used as "ceiling" treatment

The <it>ACE</it> gene D/I polymorphism as a modulator of severity of cystic fibrosis

<p>Abstract</p> <p>Background</p> <p>Cystic Fibrosis (CF) is a monogenic disease with complex expression because of the action of genetic and environmental factors. We investigated whether the <it>ACE</it> gene D/I polymorphism is associated with severity of CF.</p> <p>Methods</p> <p>A cross-sectional study was performed, from 2009 to 2011, at University of Campinas – UNICAMP. We analyzed 180 patients for the most frequent mutations in the <it>CFTR</it> gene, presence of the <it>ACE</it> gene D/I polymorphism and clinical characteristics of CF.</p> <p>Results</p> <p>There was an association of the D/D genotype with early initiation of clinical manifestations (OR: 1.519, CI: 1.074 to 2.146), bacterium <it>Burkholderia cepacia</it> colonization (OR: 3.309, CI: 1.476 to 6.256) and Bhalla score (BS) (p = 0.015). The association was observed in subgroups of patients which were defined by their <it>CFTR</it> mutation genotype (all patients; subgroup I: no mutation detected; subgroup II: one <it>CFTR</it> allele identified to mutation class I, II or III; subgroup III: both <it>CFTR</it> alleles identified to mutation class I, II and/or III).</p> <p>Conclusion</p> <p>An association between the D allele in the <it>ACE</it> gene and the severity of CF was found in our study.</p

Long term outcome of acute pancreatitis in Italy: Results of a multicentre study

Background: In Italy, no long-term studies regarding the natural history of acute pancreatitis have been carried out. Aim: To report the results of a follow-up on a large series of patients hospitalised for pancreatitis. Methods: Data of 631 patients admitted to 35 Italian hospitals were retrospectively evaluated 51.7 ± 8.4 months after discharge. Results: The average recovery time after mild or severe pancreatitis was 28.2 and 53.4 days respectively. Fourteen sequelae were not resolved and 9 cases required late surgical intervention. Eighty patients (12.7%) had a second hospital admission. Of the patients with mild biliary pancreatitis, 67.9% underwent a cholecystectomy. The overall incidence of relapse was 12.7%. Mortality was 9.8% and no death was related to pancreatitis. Three patients died from carcinoma of the pancreas. Conclusion: Reported recovery time after an attack of pancreatitis was longer than expected in the mild forms. The treatment of sequelae was delayed beyond one year after discharge. The incidence of relapse of biliary pancreatitis in patients not undergoing a cholecystectomy was low, due to endoscopic treatment. Mortality from pancreatic-related causes is low, but there is an association with malignant pancreatic or ampullary tumours not diagnosed during the acute phase of the illness
