Advances in treating cancer, heart disease and other major health conditions in recent decades have extended life spans for millions of people. However, chronic kidney disease is an outlier, with cases accelerating at a faster pace than all other noninfectious diseases, according to a study from Washington University School of Medicine in St. Louis and […]
Scientists hoping to develop better treatments for kidney disease have turned their attention to growing clusters of kidney cells in the lab. One day, so-called organoids – grown from human stem cells – may help repair damaged kidneys in people or be used to test drugs developed to fight kidney disease. But new research from […]
Patients with acute myeloid leukemia (AML), an aggressive cancer of the blood, often are treated with stem cell transplantation, in which a compatible donor’s blood-forming cells are transplanted into a patient. The donor’s immune cells then attack and kill the leukemia cells. But even if this treatment initially is successful, many patients experience a recurrence […]
While studying viruses best known for infecting the brain, researchers at Washington University School of Medicine in St. Louis stumbled upon clues to a conundrum involving a completely different part of the anatomy: the bowel, and why some people possibly develop digestive problems seemingly out of the blue. The researchers found that viruses such as […]
A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells, according to new research at Washington University School of Medicine in St. Louis.

The findings raise the possibility that reducing pollution may lead to a […]
Some 50 to 80 percent of cancer patients taking powerful chemotherapy drugs develop diarrhea, which can be severe and in some cases life-threatening. Their problems occur when contractions in the smooth muscle lining the gastrointestinal (GI) tract go haywire as food is digested. The same issues can occur in people with irritable bowel syndrome and […]
When Kim Morey was a young girl, a mysterious illness affected her family, striking relatives one by one at around the age of 40, she recalled. “My dad’s grandmother had it, and then his mother and her sisters,” Morey said. “Then my dad’s cousin. And soon after that, my dad started showing symptoms.” For years, […]
Scientists have zeroed in on a culprit that spurs damaging inflammation in the heart following a heart attack. The guilty party is a type of immune cell that tries to heal the injured heart but instead triggers inflammation that leads to even more damage. Further, the researchers have found that an already approved drug effectively […]
Most people with the deadly brain cancer glioblastoma die less than 18 months after diagnosis. But a multicenter clinical trial of a personalized vaccine that targets the aggressive cancer has indicated improved survival rates for such patients. The study appears May 29 in the Journal of Translational Medicine. The phase three clinical trial included 331 […]

Two new studies of patients with difficult-to-control asthma show that the eczema drug dupilumab alleviates asthma symptoms and improves patients’ ability to breathe better than standard therapies. Dupilumab, an injectable anti-inflammatory drug, was approved in 2017 by the Food and Drug Administration as a treatment for eczema, a chronic skin disease.
A new study shows that a kind of E. coli most associated with “travelers’ diarrhea” and children in underdeveloped areas of the world causes more severe disease in people with blood type A. The bacteria release a protein that latches onto intestinal cells in people with blood type A, but not blood type O or B, according […]
Chikungunya virus is a growing threat to the United States and other regions of the world as the mosquito that carries the virus expands its reach. Telltale symptoms of chikungunya infection are fever and joint pain that last about a week. But in up to half of patients, the virus can cause a debilitating form […]
Visceral fat differs from subcutaneous fat in that it releases fatty acids and inflammatory substances directly into the liver rather than into the general circulation. Some experts believe this may play a direct role in causing the diseases linked to abdominal obesity. But not everyone agrees. Samuel Klein, who heads the Center for Human Nutrition […]
For some people, particularly those who are elderly, even a light touch of the skin or contact with clothing can lead to unbearable itching. What’s worse, anti-itch treatments, including hydrocortisone, don’t provide much relief for this type of itching. Now, researchers at Washington University School of Medicine in St Louis have discovered, in mice, why […]
An investigational drug in clinical trials for rheumatoid arthritis prevents a common, life-threatening side effect of stem cell transplants, new research from Washington University School of Medicine in St. Louis shows.

The very rare animals that reproduce asexually — only about one in 1,000 of all living vertebrate species — are thought to be at an evolutionary disadvantage compared with their sexually reproduced counterparts. But that theory doesn’t hold true regarding the Amazon molly, an all-female fish species that has thrived for millennia in the fresh […]
The current influenza outbreak – the worst across the United States in nearly a decade – is worrisome but still far less dire than a pandemic flu, which could kill millions. Such pandemics are exceedingly difficult to predict, but new research at Washington University School of Medicine in St. Louis offers details about flu viruses […]
A new anti-cancer strategy wields light as a precision weapon. Unlike traditional light therapy — which is limited to the skin and areas accessible with an endoscope — this technique can target and attack cancer cells that have spread deep inside the body, according to researchers at Washington University School of Medicine in St. Louis. […]
Respiratory infections peak during the winter months, and most people recover within a few weeks. But for those with a rare genetic lung disease, the sniffling, coughing and congestion never end. The tiny hairlike structures called cilia that normally sweep mucus through the airways don’t work properly in people with what’s known as primary ciliary […]
More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain’s ability to repair damaged neurons and […]
