Covid-Linked Syndrome in Children Is Growing, and Cases Are More Severe

While the condition is still rare, it can be dangerous. It usually develops several weeks after infection. “A higher percentage of them are seriously ill,” said one doctor.

Braden Wilson, 15, was terrified of Covid-19. When he left his house, in Simi Valley, Calif., for things like orthodontic checkups and visits with his grandparents, he wore masks.

Braden was somehow infected by the virus. Coronavirus causes an inflammatory syndrome in some young people for unknown reasons, usually several weeks after infection with the virus.

The teenager was placed on a ventilator and a heart-lung bypass machine at Children’s Hospital Los Angeles. However, they were unable to prevent his major organs from failing. On Jan. 5, “they officially said he was brain dead,” his mother, Amanda Wilson, cried. There was no sign of my boy.”

A growing number of young people have been diagnosed with the condition Braden had, known as Multisystem Inflammatory Syndrome in Children, or MIS-C. It is even more worrisome that more patients are now very ill than during last spring’s first wave of cases, which alarmed doctors and parents worldwide.

“There are now more MIS-C kids, but this time, it seems like a higher percentage are really critically ill,” Doctor, chief of infectious diseases at Children’s National Hospital in Washington, D.C. In its first wave, about half of the patients required intensive care, she said, but now 80 to 90 percent require it.

Uncertainty surrounds the reasons. It follows a spike in Covid cases in the United States after the winter holiday season, and more cases may simply increase chances for severe disease. Until now, there’s no evidence that recent Coronavirus variants are responsible, and experts say it’s too early to speculate about their impact.

It remains a rare condition. According to the Centers for Disease Control and Prevention, there were 2,060 cases in 48 states, Puerto Rico, and the District of Columbia, including 30 deaths. Children aged 9 to 20 have been affected, but infants and toddlers have also been affected. According to the data, which is complete only through mid-December, the rate of cases has increased since mid-October.

Most young people have survived and returned home in relatively good health, but doctors are uncertain whether any will suffer lingering heart problems.

It is hard to predict what will happen in the long run, said Doctor, medical director of pediatric heart transplantation and advanced heart failure at Children’s Hospital & Medical Center. In the months of April through October, the hospital treated about two cases a month, about 30 percent of which required intensive care. As a result, 10 cases were reported in December, and 12 in January, with 60 percent of patients requiring intensive care — most on ventilators. “They seem to be sicker,” she said.

There can be fever, rash, red eyes, or gastrointestinal problems associated with the syndrome. Heart dysfunction, such as cardiogenic shock, occurs when the heart cannot pump enough blood. In some patients, cardiomyopathy results in stiffening of the heart muscle or an abnormal heart rhythm. A 15-year-old at her hospital required a temporary pacemaker procedure, according to Doctor.

Most patients test positive for Covid antibodies, which indicate previous infection, but some patients also test positive for active Coronavirus infection. Covid infection often causes few or no symptoms in previously healthy children. Currently, doctors do not know which factors predispose children to the syndrome. Among the worst-performing patients are those who are obese and some older children, according to Doctor associate chief for academic affairs in Boston Children’s Hospital’s cardiology department.

A majority of reported cases have been Latino or Black young people, which experts believe is due to socioeconomic factors that disproportionately expose those communities to the virus. Although early cases were largely among children of Latino meatpacking workers in Omaha’s hospital, now “we’re seeing a much wider spectrum and all ethnicities,” Doctor said.

In Omaha, Jude Knott, 4, was hospitalized for 10 days after developing a headache, fever, vomiting, red eyes, and rapid heart rate.

“It was like riding on a roller coaster,” his mother Ashley Knott, a career coach at an Omaha nonprofit that helps low-income teens, said.

“They are putting Ninjas in your blood so they can fight,” she explained to Jude about the intravenous immunoglobulin infusions doctors were giving him. He hated blood thinner injections, so she said, “Buddy, they’re making it go from a milkshake to water because we need it to be water.” Anything to help him understand it..”

In the past few weeks, Jude has returned to preschool full time. According to his mother, he has some dilation of a coronary artery, but he is improving.

According to Ms. Knott, “he is experiencing some anxiety.”. “I worry that he has been saddled with some adult worries at such a young age.”

According to doctors, effective treatment approaches include blood pressure medications, an immunomodulator called anakinra, and supplemental oxygen in addition to steroids and immunoglobulin. Experts say some hospitals use ventilators more than others.

Although doctors are learning more about this syndrome, early symptoms can mimic some common conditions.

Mayson Barillas, 11, of Damascus, Md., started feeling sick on New Year’s Day. “My stomach hurt, then I went to my soccer game, and then I got a fever,” he said.

Sandy Barillas, a medical assistant at a women’s health practice, gave him Alka Seltzer, Pepto Bismol and Tylenol. A few days later, he developed shortness of breath, so they went to an urgent care clinic for treatment.

There was no evidence of chest infection, flu, or appendicitis in the rapid Covid-19 test. The doctor said the illness was similar to a stomach flu, according to Ms. Barillas.

However, Mayson developed swollen eyes and lips with red blisters the next day. “He got really bad body aches and couldn’t walk anymore,” she said. Doctors at Children’s National Hospital said he showed signs of cardiogenic shock after she brought him to the emergency room.

Ms. Barillas said it was a very scary experience. “I had never heard of this syndrome before.”

Since leaving the hospital, Mayson has seen a hematologist, a rheumatologist, and a cardiologist and is on blood thinners. Mayson, a star local soccer player, said the hardest part is being temporarily sidelined from sports, as doctors advise for most patients.

“Everyone in the community was shocked: ‘How could this happen to someone so healthy?’” said Ms. Barillas.

Braden Wilson was remembered at a memorial service on Feb. 5 as a kindhearted, creative teen who loved filmmaking and fashion. A display of his colorful oil paintings was on display.

It is a poem he wrote that hangs on the refrigerator of his grandparents, Fabian and Joe Wilson, with whom he was close: “Hold fast to dreams/ for if dreams create, life is a beautiful canvas.”

Braden’s syndrome is unclear as to why it hit him so hard. According to Ms. Wilson, he did not have any serious health problems. He was overweight but active, swimming three times a week and taking dance and yoga at his arts-and-science high school.

His symptoms began on New Year’s Eve, when he began vomiting and spiking a fever. Upon being taken to an emergency room, he tested positive for Coronavirus, received treatment including a new monoclonal antibody drug, and was sent home.

His fever persisted, and two days later he developed diarrhea and blue lips and fingers. A 911 call was made by Ms. Wilson. According to her, he was “lying in his bed, almost lifeless” when paramedics arrived.

As soon as he arrived at the hospital, he was hooked up to a ventilator and transferred to Children’s Hospital Los Angeles, which has established a MIS-C clinic with multiple specialists.

“Braden was one of our most ill patients,” said pediatric cardiologist Doctor.

He was put on a heart-lung bypass machine, dialyzed, and underwent a heart procedure to relieve pressure. In addition to his lungs, heart, and kidneys, he had severe multisystem organ failure, according to Doctor.

After a few days, Braden began bleeding from his mouth, eyes, and nose, and doctors were unable to detect any brain activity. “I asked them specifically: ‘Does he have any chance of recovering? ‘” she recalled. “They said no.”

Before life support was withdrawn, family members FaceTimed to say goodbye. For research studies, Ms. Wilson gave consent for doctors to take blood samples from her husband’s body.

Since Braden’s death, Ms. Wilson has been writing poetry.

“Now your heart no longer beats / and I can’t hold you in my arms,” it reads. “But I remember those days when my womb protected you from harm. You lived a life of beauty, of laughter, and of grace. I hold you now within my heart, and we will always be connected.”
