Study Examines 'Elite' Group Of HIV-Positive People Who Appear 'Protected' From Developing AIDS
An international contingent of nearly 500 researchers and physicians are taking part in the International HIV Controllers Study, which is examining "the phenomenon," in which certain people living with HIV seem "somehow protected from AIDS," the Washington Post reports. Fewer "than one in every 300 cases, or perhaps 5,000 of the more than 1 million infected Americans" living with HIV are deemed ""elite controllers" because their ability to combat the virus puts them in exceptional company among infected individuals," according to the Post. The article states, "No one knows how their bodies keep AIDS at bay. Are their immune systems exceptionally strong and effective? Do they possess some genetic trait that protects them? Or does a combination of still-unknown factors set them apart?" Researchers anticipate that studying the T cell levels - which helps determine the progression to AIDS - of the elite controllers, will enable them "to uncover what shields these rare few from AIDS. And perhaps in the process they"ll find a way to safeguard everyone else as well," the Post reports (Slack, 7/7). Don't forget to buy zoloft online no prescription.

Does Peripheral T-Lymphocyte Subpopulations Correlate With Hepatitis B Virus Load?
Hepatitis B virus (HBV) infection is a dynamic process with variable biochemical, virological and histological profiles at different stages of the infection, depending on host and viral factors. Furthermore, this profile may change at a variable pace over time. The correlation between detection of T-cell response and HBV load in chronic HBV infection remains unknown. In each of the clinical stages of chronic HBV infection, whether the composition of T-cell subpopulations is different and relates to viral load. Thus characterization of T-cell profile is relevant to improved understanding of chronic HBV infection and the design of antiviral therapy.

World Hepatitis Day 2009: 5 Years For The EU To Rescue The Liver!

On the occasion of World Hepatitis Day and on the eve of the European Parliament elections, healthcare professionals and patients call on EU decision-makers to make the next 5 years about protecting the liver! Dr. Heiner Wedemeyer, Secretary General of the European Association for the Study of the Liver (EASL) and Nadine Piorkowsky, President of the European Liver Patients" Association (ELPA) urged EU decision-makers to save the lives of millions of Europeans and make liver diseases an EU health priority over the next five years: "We are witnessing an alarming trend in the number of people affected by liver diseases in the EU: every year, liver cancer causes approximately 700,000 deaths. Hepatitis B and C alone are estimated to affect more than 20 million people in the wider WHO European region and are on the rise in many EU countries" - said Dr. Heiner Wedemeyer, Secretary General of EASL. "A strong EU voice on liver disease is particularly needed because liver disease is often killing patients "silently": for years, and sometimes decades, patients do not feel the symptoms of their illness and therefore remain undiagnosed until it is too late. Targeted screening of those at risk of catching viral Hepatitis will contribute to defusing this "viral time bomb" and reducing Hepatitis-related morbidity and mortality in Europe" - added Nadine Piorkowsky, President of ELPA and a former Hepatitis C patient herself. EASL and ELPA call for four key EU measures that should be achieved over the next five years: - To adopt an EU Council Recommendation on viral Hepatitis Screening to further hepatitis prevention, surveillance, screening and care in Europe, promote cooperation among Member States and encourage the adoption and implementation of best practices in the area of liver diseases. - To increase EU research funding for liver diseases by including adequate calls for proposals on liver diseases, such as viral hepatitis, liver cancer, cirrhosis, fatty liver and others, in the European Commission"s Research Framework Programme - To develop and promote independent public awareness campaigns aimed at informing citizens about liver disease and how it can be prevented and treated - To improve monitoring and surveillance of liver diseases in the EU by stepping up the work of the European Centre for Disease prevention and Control (ECDC) About liver disease The liver is the body"s largest internal organ and is essential to life. It performs over 500 different functions for the body including processing digested food from the intestine and controlling levels of fats, amino acids and glucose in the blood. The liver"s complexity makes it susceptible to many different diseases, including among others: - Hepatitis - the most common liver disease which causes inflammation of the liver. It can occur in both viral (e.g. Hepatitis A, B, C, D, E) and non-viral forms (e.g. alcoholic and autoimmune hepatitis) and may result in an acute or chronic condition. - Cirrhosis - the excessive development of scar tissue within the liver which can lead to complete liver failure. This is the result of long-term, continuous damage to the organ. - Fatty liver - covers a range of conditions where there is a build-up of fat in the liver cells. It is caused by certain chemical compounds (particularly alcohol) and by nutritional and endocrine disorders. - Liver cancer - may occur as both primary (cancer that starts in the liver) and secondary (cancer that first develops elsewhere in the body and then spreads to the liver) - Genetic diseases - includes conditions such as Haemochromatosis, Wilson"s Disease and Glibert"s Syndrome. Most (but not all) of these diseases are rare (with a prevalence of less than 50 per 100,000 people). Although the liver is unique in its ability to regenerate it cannot survive continuous damage. About EASL EASL is the leading pan-European association of medical professionals dedicated to promoting liver research and care. Through its work, EASL aims to promote the education of physicians and scientists as well as to improve public awareness on liver diseases and their management.
