Co-infection by human immunodeficiency virus and hepatitis B and C viruses is quite common because they share similar routes of transmission. The introduction of highly active antiretroviral therapy has significantly improved the life expectancy of HIV-infected patients in the last few years. However, chronic viral hepatitis represents an emerging cause of morbidity and mortality in this population, either as a result of end-stage liver disease or as a consequence of hepatotoxicity induced by antiretroviral drugs. The main goal of the Consensus Conference was to establish specific recommendations for the management of chronic viral hepatitis B and C in HIV-infected patients. The role of orthotopic liver transplantation for co-infected individuals with end-stage liver disease was also assessed. 相似文献
The Authors for the Live Organ Donor Consensus Group
JAMA. 2000;284:2919-2926.
Objective To recommend practice guidelines for transplantphysicians, primary care providers, health care planners, andall those who are concerned about the well-being of the liveorgan donor.
Participants An executive group representing the NationalKidney Foundation, and the American Societies of Transplantation,Transplant Surgeons, and Nephrology formed a steering committeeof 12 members to evaluate current practices of living donortransplantation of the kidney, pancreas, liver, intestine, andlung. The steering committee subsequently assembled more than100 representatives of the transplant community (physicians,nurses, ethicists, psychologists, lawyers, scientists, socialworkers, transplant recipients, and living donors) at a nationalconference held June 1-2, 2000, in Kansas City, Mo.
Consensus Process Attendees participated in 7 assignedwork groups. Three were organ specific (lung, liver, and kidney)and 4 were focused on social and ethical concerns (informedconsent, donor source, psychosocial issues, and live organ donorregistry). Work groups' deliberations were structured by a seriesof questions developed by the steering committee. Each workgroup presented its deliberations to an open plenary sessionof all attendees. This information was stored and shaped intoa statement circulated electronically to all attendees for theircomments, and finally approved by the steering committee forpublication. The term consensus is not meant to convey universalagreement of the participants. The statement identifies issuesof controversy; however, the wording of the entire statementis a consensus by approval of all attendees.
Conclusion The person who gives consent to be a live organdonor should be competent, willing to donate, free from coercion,medically and psychosocially suitable, fully informed of therisks and benefits as a donor, and fully informed of the risks,benefits, and alternative treatment available to the recipient.The benefits to both donor and recipient must outweigh the risksassociated with the donation and transplantation of the livingdonor organ.
The Brazilian Consensus on Gastroesophageal Reflux Disease considers gastroesophageal reflux disease to be a chronic disorder related to the retrograde flow of gastroduodenal contents into the esophagus and/or adjacent organs, resulting in a variable spectrum of symptoms, with or without tissue damage. Considering the limitations of classifications currently in use, a new classification is proposed that combines three criteria-clinical, endoscopic, and pH-metric-providing a comprehensive and more complete characterization of the disease. The diagnosis begins with the presence of heartburn, acid regurgitation, and alarm manifestations (dysphagia, odynophagia, weight loss, GI bleeding, nausea and/or vomiting, and family history of cancer). Also, atypical esophageal, pulmonary, otorhinolaryngological, and oral symptoms may occur. Endoscopy is the first approach, particularly in patients over 40 yr of age and in those with alarm symptoms. Other exams are considered in particular cases, such as contrast radiological examination, scyntigraphy, manometry, and prolonged pH measurement. The clinical treatment encompasses behavioral modifications in lifestyle and pharmacological measures. Proton pump inhibitors in manufacturers' recommended doses are indicated, with doubling of the dose in more severe cases of esophagitis. The minimum time of administration is 6 wk. Patients who do not respond to medical treatment, including those with atypical manifestations, should be considered for surgical treatment. Of the complications of gastroesophageal reflux disease, Barrett's esophagus presents a potential development of adenocarcinoma; biopsies should be performed, independent of Barrett's esophagus extent or location. In this regard the designation "short Barrett's" is not important in terms of management and prognosis. 相似文献
Sputum induction (SI) is the gold standard approach to the non-invasive study of airway inflammation. The differential count of inflammatory cells for SI allows patients with asthma to be classified according to inflammatory phenotypes and predicted therapeutic responses. Since SI involves the generation of aerosols, there is a need to establish a protocol to ensure biosafety in clinical practice during the current COVID-19 pandemic. The multidisciplinary consensus on SI described in this article was developed by 22 experts in SI from different Spanish hospitals who drew on available scientific evidence in achieving consensuated opinions, compiled by means of an electronic survey. We hope that these unified criteria and recommendations will guide health professionals in implementing SI sampling and processing procedures as safely as possible during the COVID-19 pandemic. 相似文献
