Skimp on Sleep and You Just May Wind Up Sick

Posted 9 Feb 2017 by Drugs.com

THURSDAY, Feb. 9, 2017 – Ever noticed that when you try to "do it all," the one thing you can count on is getting sick? Now, a new study suggests why: if you don't get enough sleep, your immune system seems to suffer. The finding comes from a study of 11 pairs of twin adults. Each pair of twins had significantly different sleeping routines. The researchers found that the twin who regularly slept less also turned out to be the one with the less potent immune system. "This is the first study to show suppressed immune gene expression in chronic sleep deprivation," said study lead author Dr. Nathaniel Watson. He's a professor of neurology at the University of Washington Medicine Sleep Center in Seattle. That, added Watson, could explain why prior research has shown that "if you expose a sleep-deprived person to a rhinovirus they are more likely to get the common cold than a person who has ...

Toxins in Your Fast-Food Packaging?

Posted 1 Feb 2017 by Drugs.com

WEDNESDAY, Feb. 1, 2017 – Many grease-resistant fast-food wrappers and boxes contain potentially harmful chemicals that can leach into food, a new study contends. Testing on more than 400 samples from restaurants nationwide revealed that nearly half of fast-food wrappers and one out of five paperboard food boxes contained detectable levels of fluorine, said lead researcher Laurel Schaider. She's an environmental chemist at the Silent Spring Institute in Newton, Mass. Previous studies have linked some fluorinated chemicals such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) to kidney and testicular cancer, low birth weight, thyroid disease, decreased sperm quality, pregnancy-induced high blood pressure, and immune system problems in children, the study authors said in background notes. Major U.S. manufacturers voluntarily phased out PFOA and PFOS for most uses ... Read more

Immune System Reboots During Sleep

Posted 4 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 4, 2017 – Researchers say they've gained new insight into how the immune system restores itself during sleep. Blood samples were taken from 14 healthy young men, average age 25, when they slept through the night and again when they stayed awake all night. The samples were analyzed for levels of T-cells, which are white blood cells that are the foundation of the immune system. When the participants got a full night's sleep, levels of all types of T-cells fell within three hours of falling asleep. But T-cell levels stayed high when the volunteers stayed awake all night. It's not clear where T-cells went when they left the bloodstream during sleep. But, previous research suggests they may accumulate in lymph nodes, according to the authors of the study published recently in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology. The rapid ... Read more

Nearly 3 Percent of U.S. Adults Have Weakened Immunity: Study

Posted 28 Oct 2016 by Drugs.com

FRIDAY, Oct. 28, 2016 – A new study reports that about 3 percent of people surveyed in the United States have a suppressed, or weakened, immune system. The statistics offer insight into the number of Americans who have immunity-suppressing conditions such as AIDS or take drugs that treat autoimmune disorders by weakening the immune system, the researchers said. The researchers believe these numbers are rising because of medical advances allowing immunosuppressed patients to live longer. Dr. Rafael Harpaz of the U.S. Centers for Disease Control and Prevention led the study. "Tracking immunosuppression over time is particularly important given the hundreds of clinical trials now under way to assess the use of immunosuppressive treatments for prevention or mitigation of common chronic diseases in highly prevalent risk groups," Harpaz and his colleagues wrote. The study authors explained ... Read more

Black Americans May Have Stronger Immune Response to Infections

Posted 21 Oct 2016 by Drugs.com

THURSDAY, Oct. 20, 2016 – Researchers say that based on laboratory studies, the cells of black Americans mount a much stronger immune response to infection than those of European-Americans. That hearty response might have a downside, though. It could play a role in black Americans' higher risk for heart disease, stroke and autoimmune inflammatory diseases, the researchers said. The findings might lead to treatments that reduce chronic health risks for African-Americans, according to the researchers. The strength of the immune response was directly related to the percentage of genes derived from African ancestors, said senior researcher Luis Barreiro. He's an assistant professor at the University of Montreal's Department of Pediatrics and researcher at the Sainte-Justine University Hospital Center in Montreal. "Basically, the more African you have in your genome, the stronger you're ... Read more

Baby's Immune System Might Hint at Autism Risk

Posted 11 May 2016 by Drugs.com

WEDNESDAY, May 11, 2016 – While the origins of autism remain mysterious, new research points to the infant immune system as a potential contributing factor. A team of Swedish and American researchers said levels of certain protein "markers" in newborns' blood seemed to predict which children would go on to develop an autism spectrum disorder. This is "important evidence that the immune system in early life may be a key determinant of later risk of autism spectrum disorders," wrote the team led by Dr. R. M. Gardner of the Karolinska Institute in Stockholm. The researchers examined blood from nearly 900 children who developed some form of autism. The children were born in Sweden between 1998 and 2000. The researchers compared those blood samples to blood from more than 1,100 kids who didn't develop the disorder. While the study can't prove cause-and-effect, babies who went on to develop ...

Gene Therapy May Offer Hope for 'Bubble Boy' Disease

Posted 20 Apr 2016 by Drugs.com

WEDNESDAY, April 20, 2016 – A new gene therapy shows preliminary promise against so-called "Bubble Boy" disease, researchers report. A small, early-stage trial assessed the safety and effectiveness of the gene therapy in five patients with Bubble Boy disease, formally known as severe combined immunodeficiency disease (SCID). Previous bone marrow transplants had failed to correct their immune function. SCID is a severe, inherited disorder that affects males and occurs in 1 in every 50,000 to 100,000 live births. It is caused by a mutation in the IL2RG gene that leaves boys with little or no immune system protection, the researchers said. According to the U.S. National Institute of Allergy and Infectious Diseases, SCID is fatal, often within the first year or two of life, unless infants receive immune-restoring treatments, such as transplants of blood-forming stem cells, gene therapy or ...

Smog Linked to Organ Rejection, Deaths in Lung Transplant Patients

Posted 29 Sep 2015 by Drugs.com

TUESDAY, Sept. 29, 2015 – Living near busy roads with high levels of air pollution raises lung transplant patients' risk of organ rejection and death, but some antibiotics lower that risk, a new study shows. Researchers examined data gathered from more than 5,700 lung transplant patients in 10 European countries between 1987 and 2013. The analysis revealed that patients who lived in areas where air pollution was above maximum levels recommended by the World Health Organization (WHO) were 10 percent more likely to die than those in areas with lower levels of pollution. But this increased risk of death was not seen among patients who took a class of antibiotics called macrolides, which include azithromycin (Zithromax) and clarithromycin (Biaxin), according to the study presented Tuesday at a meeting of the European Respiratory Society in Amsterdam. "Short and long-term exposure to air ... Read more

Immune System Genes May Change With the Seasons: Study

Posted 12 May 2015 by Drugs.com

TUESDAY, May 12, 2015 – When the seasons change, your immune system response may also change, British researchers report. These findings might explain why conditions such as rheumatoid arthritis and heart disease are worse in the winter than in the summer, the new study finds. The researchers from the University of Cambridge analyzed genes from more than 16,000 people worldwide, including those from both the Northern and Southern hemispheres. They found that the activity of nearly one-quarter of the genes differed according to the time of the year. Some are more active in winter and some are more active in summer, the research revealed. Seasons also affect our immune cells, and the composition of our blood and fat, according to the study. Findings were published May 12 in the journal Nature Communications. It's been known that there are seasonal variations in a number of conditions, ... Read more
