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.
The gluten-free diet craze is both reassuring and upsetting to people with celiac disease who are allergic to the nutrient, a small study suggests.
People with celiac disease say they're happy to have more food choices at stores and restaurants. But some with celiac sense a growing stigma as other people voluntarily go gluten-free. And many patients fear people see them as "high-main...
It's not always easy -- even for doctors -- to tell if someone has type 1 or type 2 diabetes when they're diagnosed as an adult.
And a new study finds mistakes are common.
That's what happened to British Prime Minister Theresa May when she was diagnosed with type 2 diabetes in 2012. She was in her 50s at the time. Despite having all of the symptoms common to type 1 diabetes...
Though psoriasis is not contagious, many Americans shun people with the skin condition, new research indicates.
The study included a cross-section of about 400 Americans who viewed images of people with visible psoriasis. Large numbers wrongly thought psoriasis was contagious or only affects the skin, and about one-third said they wouldn't want to invite people with the condition into...
A baby's immune system kicks into high gear immediately after birth, a new study finds.
Changes in a newborn's immune system have been difficult to assess because doing so has relied on samples taken from the umbilical cord immediately after birth. In this study, researchers used a new immune cell analysis technique to follow 100 premature and full-term babies for their first few week...
Organ transplant recipients are at increased risk for skin cancer and need to protect themselves, a dermatologist warns.
"Individuals who receive organ transplants need to take immunosuppressive medications for the rest of their lives, and this makes it more difficult for their bodies to fight disease, including skin cancer," said Dr. Christina Lee Chung. She is former director of th...
