Air pollution might increase the risk for multiple sclerosis (MS), Italian researchers report.
They found that in places with low levels of tiny particles of air pollution called particulate matter, the risk for MS was lower than in areas where those levels were high. In urban areas, the risk was 29% higher than in rural areas.
The severity of COVID-19 illness may be influenced by what researchers call "cytokine storms."
In a new study, investigators assessed 522 COVID-19 patients, aged 5 days to 97 years, who were admitted to two hospitals in Wuhan, China, in December and January. The study also included a "control group" of 40 healthy people.
Compared to the control group, 76% of COVID-19 pat...
Hydroxychloroquine is a key therapy for the autoimmune disease lupus, but interest in it as a potential COVID-19 treatment could make it hard for lupus patients to obtain, experts warn.
Hydroxychloroquine is the only medication known to increase survival in patients with systemic lupus. That's the most common form of lupus, a disease in which the immune system attacks different parts ...
As researchers hunt for ways to treat severe COVID-19 infections, a new trial will ask whether an old arthritis drug can prevent serious complications in the first place.
The medication, called colchicine, is an oral anti-inflammatory that has long been prescribed for gout, a form of arthritis. Its history goes back thousands of years, and the drug was first sourced from the autumn cr...
One of the few bright spots in the COVID-19 pandemic has been the perception that children are mostly spared from its worst effects. But what about kids already at risk of contracting serious infections due to a compromised immune system? Do they have the same protection?
"One group we always worry about when it comes to viral illnesses is immunocompromised children," said Dr. Reggie...
People with asthma and other lung diseases are at increased risk for serious complications from COVID-19, caution experts from the American Lung Association.
"Everyone's health is at risk from COVID-19, and those living with a lung disease or who are immunocompromised may be more vulnerable to the impacts of the virus," said Dr. Albert Rizzo, the association's chief medical officer.
New research suggests that having an underlying health condition might be one of the most significant risk factors for developing a severe case of COVID-19.
Scientists at the U.S. Centers for Disease Control and Prevention took a look at a group of U.S. adult COVID-19 patients and found roughly three-quarters of those who wound up in the hospital had at least one underlying health iss...
Smokers and vapers who get COVID-19 can probably expect a more severe infection, health experts warn.
Many advisories have focused on the risk facing older people, those with chronic conditions such as diabetes, and people with compromised immune systems, such as cancer patients. But doctors also caution that users of electronic cigarettes and tobacco are more in danger from the new ...
As the coronavirus pandemic continues its relentless spread around the world, the greatest worry has been for older people. But experts stress that age is not the sole determinant of risk for severe illness or death.
"The elderly and people with chronic diseases have the highest risk. If you're not sure if you're at a higher risk, talk to your doctor," said Dr. Susan Bleasdale, a spo...
A variant of a common herpes virus may play a role in the development of multiple sclerosis (MS), Swedish researchers say.
They analyzed the blood of about 8,700 MS patients and a control group of more than 7,200 people without MS. They were looking for antibodies against proteins of two variants (A and B) of human herpesvirus 6 (HHV-6), which has been linked with MS.
The latest version of the so-called artificial pancreas system helped people with type 1 diabetes gain even better control of their blood sugar levels than current technology does, a new study reports.
The device combines an insulin pump, a continuous glucose monitor and a computer algorithm. The system measures blood sugar levels and delivers insulin automatically when levels rise. ...
Children diagnosed with type 1 diabetes at an early age have slowed growth in brain areas linked to mild cognitive deficits, new research suggests.
The study compared MRIs of the brain in kids with type 1 diabetes to age-matched children without the condition. Researchers also saw that areas of slower brain growth were associated with higher average blood sugar levels.
The idea behind immunotherapy for peanut allergy is appealing in its simplicity: Ask a patient to eat tiny amounts of peanut every day, and over time their immune system will become desensitized to it.
Unfortunately, this cure might be doing more harm than the allergy itself, a new evidence review suggests.
People who undergo immunotherapy for their peanut allergies wind up with...
Almost one in five multiple sclerosis patients may be misdiagnosed with the autoimmune disease, according to a new study.
Of 241 previously diagnosed multiple sclerosis (MS) patients referred to two major Los Angeles medical centers for treatment, nearly 18% did not actually have the autoimmune disease, the researchers found.
Patients with kidney failure who are on dialysis or have received a transplant have a sharply higher risk of dying from cancer, Australian researchers report.
In fact, compared with people who don't have kidney failure, they have more than double the odds of cancer death. The odds are particularly high among patients aged 20 to 34, for whom the risk is 11 times higher, the researcher...
HPV vaccination rates for younger American adolescents are alarmingly low, researchers say.
"While we have seen gains in HPV vaccination coverage, we are still falling behind at the younger ages," said study lead author Robert Bednarczyk. He'sassistant professor of global health and epidemiology at Emory University in Atlanta.
Human papillomavirus (HPV) is a sexually transmi...
People who take prescription opioid painkillers are at increased risk for pneumonia, especially those with HIV, a new study suggests.
The findings support concerns that prescription opioids can weaken the immune system. Doctors who prescribe opioids need to reduce patients' risk of pneumonia through vaccination and by encouraging them to stop smoking, the researchers said.
More than 10 percent of U.S. adults have a food allergy -- and nearly double that believe they do, a new study estimates.
Researchers found that 19 percent of those surveyed thought they had a food allergy. But when the investigators dug into people's symptoms, they found that only 10.8 percent reported "convincing" signs of a true allergy.
Deaths and complications among pregnant women with lupus have declined in the United States over the past two decades, a new study finds.
Lupus, also called systemic lupus erythematosus (SLE), is a chronic autoimmune disease that causes inflammation in many parts of the body, including the kidneys, skin and joints, as well as the tissue lining the lungs, heart and brain.
