Researchers at the La Jolla Institute for Allergy & Immunology have found that previous influenza infections may provide at least some level of immunity to the H1N1 “swine” flu. “The question we asked was, “Is the swine flu more like the seasonal flu or like a totally new strain of influenza where there would be no immunity?,” said Alessandro Sette, Ph.D., an internationally recognized vaccine expert and director of the La Jolla Institute’s Center for Infectious Disease.
As the number of deaths related to the pandemic H1N1 virus, commonly known as “swine flu,” continues to rise, researchers have been scrambling to decipher its inner workings and explain why the incidence is lower than expected in older adults.

A new study by Mount Sinai researchers has for the first time found that patients with more difficult to treat forms of hepatitis C are half as likely to initiate treatment for the disease, when compared to patients with hepatitis C that is easier to treat. Marital status also affected whether patients chose treatment, as did whether or not they had other diseases. The study is published in the November 1 issue of Journal of Health Care for the Poor and Underserved.

In Bangladesh cholera epidemics occur twice a year. Scientists have tried, without success, to determine the causes – and advance early detection and prevention efforts. Researchers from Tufts University have proposed a link between cholera and fluctuating water levels in the region's three principal rivers – the Ganges, Brahmaputra and Meghna.
In contrast with some common perceptions regarding 2009 influenza A(H1N1) infections, an examination of cases in California indicates that hospitalization and death can occur at all ages, and about 30 percent of hospitalized cases have been severe enough to require treatment in an intensive care unit, according to a study in the November 4 issue of JAMA.
Clinical researchers at Princess Margaret Hospital (PMH) have confirmed that patients with oropharyngeal squamous cell cancer (“tonsil cancer”) harbour a common type of human papilloma virus (HPV16), but also that such cancers are very sensitive to radiation. For some patients, this may mean successful treatment with radiation alone and avoiding the side effects of chemotherapy.
The immune system's T cells are both jury and executioner. How they shift from one role to another has been a mystery. Dana-Farber investigators report that when a T cell’s “receptors” lock onto antigens, parts of the receptors bend and signal the T cell to change from scanning to fighting mode.
MedImmune announced today it will present four abstracts at the 47th Annual Meeting of Infectious Disease Society of America (IDSA) being held here October 29 through November 1, 2009.

Trials find that the risk of male HIV acquisition is increased among men with larger foreskins.
An experimental drug cocktail that includes three prescriptions now widely available offers the best hope in developing a single agent to treat drug-resistant H1N1 swine flu, says a UAB virology researcher. The combo of oseltamivir, amantadine and ribavirin drug works better than currently recommended single or double antiviral therapies used to treat both seasonal and swine flu strains.
Seattle and Ugandan researchers collaborate to study and treat infection-related cancers.
Mayo Clinic researchers have found that a sometimes deadly stomach bug, Clostridium difficile, is on the rise in outpatient settings.

These findings were presented today at the 2009 American College of Gastroenterology (ACG) Annual Meeting in San Diego.
Results of a new study reveal that a seven-day course of LOAD therapy is superior to LAC at eliminating the H. pylori bacterium in patients with gastritis and peptic ulcers.

Tracking and understanding the patterns of H1N1’s spread remains crucial to keeping a big-picture look at the disease. Says UAB’s chief of travel medicine, ‘Back in 1918 and 1919 when we had the great flu epidemic, it took six months or more to spread across the world. The new H1N1 swine flu spread across the world in six weeks.’

An outbreak of bloodstream infections appears to have been caused by the contamination of pre-filled heparin and saline syringes made by a single company, according to a report in the October 12 issue of Archives of Internal Medicine. The subsequent investigation revealed that the company was not in compliance with safety regulations and identified challenges and areas for improvement in medication monitoring systems.
Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified the genetic mechanisms involved in the formation and survival of L-form bacteria. L-form bacteria, which were first discovered in the 1930s, are morphological variants of classical bacteria that lack a cell wall. These bacteria are believed to form in response to cell wall stress from certain antibiotics or the body’s immune attack, and are suspected to be associated with antibiotic-resistant infections.
Viruses such as HIV and influenza take safe harbor in cells, where they cannot be recognized directly by the immune system. The immune response relies on infected cells announcing the presence of the virus by studding their exterior with fragments of the virus lurking within.
Although a wide spectrum of human papillomavirus is seen across the population of India, HPV-16 and HPV-18 are the most common types and a vaccination targeting these types could eliminate 75 percent of the cervical cancers in the region, according to data presented at the American Association for Cancer Research Frontiers in Basic Cancer Research Meeting.
Infectious diseases currently cause about one-third of all human deaths worldwide, more than all forms of cancer combined. Advances in cell biology and microbial genetics have greatly enhanced understanding of the cause and mechanisms of infectious diseases. Researchers from Thomas Jefferson University, the Pasteur Institute in Paris, and Yale University reported in PLoS ONE, a way in which intracellular pathogens exploit the biological attributes of their hosts in order to escape destruction.
Infectious disease experts are awaiting an infinitesimal event of momentous importance: the mutation of the novel H1N1 influenza virus. “The Centers for Disease Control and Prevention and the World Health Organization are constantly monitoring the virus as it spreads,” says John Tudor, Ph.D., a microbiologist and professor of biology at Saint Joseph’s University in Philadelphia, “but there is no way to predict where, when or if mutation will occur.”
Researchers today announced the opening for enrollment of the first ever study using patients’ cells carrying an engineered T cell receptor to treat HIV. The trial may have important implications in the development of new treatments for HIV potentially slowing – or even preventing – the onset of AIDS.
