Focusing on new directions of viral hepatitis care and research

The editors of Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute, are pleased to announce the publication of this year\'s highly anticipated special 13th issue. Published each May, the 13th issue is devoted to a particular gastroenterological topic of broad interest; this year\'s topic is viral hepatitis. In conjunction with editor-in-chief M. Bishr Omary, MD, PhD, this issue was developed by Gastroenterology\'s experts in viral hepatitis: Senior Associate Editor Anna S. Lok, MD, AGAF, and Associate Editor Jean-Michel Pawlotsky, MD, PhD. Their expertise guided the contributing authors - an outstanding group of thoughtful expert international leaders. \"Our goals in this special issue of Gastroenterology are to give readers an up-to-date insight into the tremendous progress made over the past few years in viral hepatitis research and care, and to guide them through complex challenges and expected future developments,\" said the editors. In this year\'s issue, classic review articles are interspersed with insightful commentaries that address critical unresolved issues and fundamental questions for the future. The content is organized into four sections, mainly related to hepatitis B virus and hepatitis C virus (HCV) infections: epidemiology and pathophysiology; diagnostic and prognostic tools; therapy and prevention; and hepatitis E virus, a neglected virus that was recently found to be clinically important in industrialized countries. No other field in hepatology and gastroenterology has grown more rapidly than viral hepatitis in the past 15 years, thanks to the considerable interest of the scientific community for diseases that involve more than 500 million patients worldwide; active support for research from governments in the U.S., Europe, Japan and Australia; and major drug industry investment for what promises to be an incredibly rewarding market for antiviral drugs. This issue not only contains classical review articles dealing with important areas for which major advances have occurred recently, but editorial-like commentaries exploring critical unresolved issues and fundamental questions for the future. The commentaries, reviews and their distinguished authors are as follows: Commentaries \"Is Hepatitis C Virus Carcinogenic?\" by Stanley M. Lemon and David R. McGivern \"HCV Infection and Metabolic Syndrome: Which Is the Chicken and Which Is the Egg?\" by Francesco Negro \"Genetic Factors and Hepatitis C Virus Infection\" by Alexander J.
