A genetic analysis of COVID-19 patients suggests that blood type might influence whether someone develops severe disease.Scientists who compared the genes of thousands of patients in Europe found that those who had Type A blood were more likely to have severe disease while those with Type O were less likely.Wednesday’s report in the New England Journal of Medicine does not prove a blood type connection, but it does confirm a previous report from China of such a link.“Most of us discounted it because it was a very crude study,” Dr. Parameswar Hari, a blood specialist at the Medical College of Wisconsin, said of the report from China. With the new work, “now I believe it,” he said. “It could be very important.”Other scientists urged caution.The evidence of a role for blood type is “tentative ... it isn’t enough of a signal to be sure,” said Dr. Eric Topol, head of the Scripps Research Translational Institute in San Diego.The study, involving scientists in Italy, Spain, Denmark, Germany and other countries, compared about 2,000 patients with severe COVID-19 to several thousand other people who were healthy or who had only mild or no symptoms. Researchers tied variations in six genes to the likelihood of severe disease, including some that could have a role in how vulnerable people are to the virus. They also tied blood groups to possible risk.Most genetic studies like this are much larger, so it would be important to see if other scientists can look at other groups of patients to see if they find the same links, Topol said.Many researchers have been hunting for clues as to why some people infected with the coronavirus get very ill and others, less so. Being older or male seems to increase risk, and scientists have been looking at genes as another possible “host factor” that influences disease severity.There are four main blood types — A, B, AB and O — and “it’s determined by proteins on the surface of your red blood cells,” said Dr. Mary Horowitz, scientific chief at the Center for International Blood and Marrow Transplant Research.People with Type O are better able to recognize certain proteins as foreign, and that may extend to proteins on virus surfaces, Hari explained.During the SARS outbreak, which was caused by a genetic cousin of the coronavirus causing the current pandemic, “it was noted that people with O blood type were less likely to get severe disease,” he said.Blood type also has been tied to susceptibility to some other infectious diseases, including cholera, recurrent urinary tract infections from E. coli, and a bug called H. pylori that can cause ulcers and stomach cancer, said Dr. David Valle, director of the Institute of Genetic Medicine at Johns Hopkins University.Bottom line: “It’s a provocative study. It’s in my view well worth publishing and getting out there,” but it needs verification in more patients, Valle said.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

A Colorado family is reaching out to the public for help in treating their 15-year-old son’s rare and debilitating skin condition.For seven years, Jaiden Rogers has suffered from stiff skin syndrome, a disease that causes the skin to harden.“When they said it was stiff skin syndrome – I was like oh good it’s only that,” said Natalie, Jaiden’s mother. “But the doctor said, ‘oh no I don’t think you understand.’ They said his skin would turn to stone. Within a month, he was in a wheelchair. It spread so fast. Within just a few months, he was starting to get it everywhere.”The condition has caused his skin to gradually tighten and harden, spreading from his legs to his hips and then to his stomach and neck.It started as a growth behind his knee. Jaiden has since lost mobility. The syndrome is a painful one as the skin thickens, limiting joint mobility. The syndrome is sparked by a mutation change, and an exact treatment is unknown.With no cure for the disease, Rogers and his family are now banking on an experimental procedure to save his life.“Doctors in Ireland are working with doctors in London. This is very expensive,” Natalie said. “The whole treatment is .5 million, because they actually have to make something for him, because he is the only child. It’s our only hope, and we are running out of time.”Natalie says her son is “turning to stone,” leaving him unable to walk and sometimes giving him trouble breathing. He sees six doctors and takes chemotherapy drugs to slow the disease’s progression.Jaiden is being treated at Children's Hospital in Aurora, Colorado. He may be the only one in the world being treated for what has been tabbed stiff skin syndrome. Altogether, there have only been a few dozen documented cases of the disease.Today, Jaiden remains confined to a wheelchair and takes chemotherapy to slow the progression. However, the condition has since spread to his stomach, chest, and neck, making it difficult for him to breathe.The family has started a GoFundMe page to raise money for the experimental treatment. The fund’s .5 million goal includes 5,000 for a medical flight to Europe. 2142

A Georgia high school teacher is under investigation after he was filmed telling a student he "might" shoot the kid in the head.Paul Hagan, a white physics teacher at Rockdale Career Academy, was filmed ranting against an unidentified black student, according to Atlanta's WSB-TV."Don't smile at me, man," Hagan is heard telling the student. "That's how people like you get shot."In the video, which WSB shared on Facebook, Hagan goes on to say, "I gotta bet by the time you're 21 somebody's gonna put a bullet right through your head. OK? And it might be me the one who does it."The video was apparently shot by another student.Officials at Rockdale Career Academy are investigating the incident. It's unclear if Hagan will face disciplinary action.Clint Davis is a reporter for the Scripps National Desk. Follow him on Twitter @MrClintDavis.
