Doctors Detail Kawasaki-Like Disease in Adult COVID-19 Patients

(Reuters Health) - During the COVID-19 pandemic, an inflammatory condition similar to Kawasaki disease has been reported in children and adolescents, and now two groups of New York doctors each describe a case, one in a 36-year-old woman and one in a 45-year-old man.

"We're still learning how COVID-19 is affecting children and adults. The better we understand the myriad of ways that COVID-19 can affect the body, the better we can tailor the treatment," said Dr. Joshua Scheers-Masters of the Maimonides Medical Center in New York City, a member of the team that treated the woman.

"This Kawasaki-like condition appears to be a delayed effect of the virus rather than immediate," he told Reuters Health by phone. "The treatment for this is different than the treatment for the direct effects of the virus, so doctors need to keep their eyes wide open in the context of this pandemic."

Kawasaki disease itself causes swelling across various systems in the body, including the skin, lymph nodes and blood vessels. Symptoms include a high fever and rash that develops into severe inflammation, and if untreated, can lead to fatal heart and brain issues. The condition typically affects children under age 5 and resolves within a few weeks after treatment.

The Multisystem Inflammatory Syndrome in Children (MIS-C) phenomenon that appears to be secondary to COVID-19 infection in children isn't exactly Kawasaki disease, but it looks similar, Dr. Scheers-Masters and colleagues note in the American Journal of Emergency Medicine.

In their report, Dr. Scheers-Masters and colleagues discuss the case of a 36-year-old woman who arrived at the emergency department with a rapid heartbeat and low blood pressure after a week of fever, abdominal pain, vomiting and diarrhea. She also showed symptoms suggestive of Kawasaki, such as pink eye, cracked lips, swollen hands and feet, redness on the palms of her hands, a large rash and swollen lymph nodes. Lab tests showed low sodium levels, high liver values and irregular blood tests. Scans also showed inflammation in the lungs, gallbladder and colon.

The patient was treated for Kawasaki Disease Shock Syndrome with aspirin, steroids and intravenous immunoglobulin to reduce inflammation and antibody issues. Within a day, her vital signs leveled out, and her lab tests shifted back to normal within six days. She also tested positive for COVID-19 antibodies, indicating a prior infection. The doctors gave her a prescription for prednisone to take at home.

And on July 10 in The Lancet, doctors at New York University reported on a 45-year-old man whose clinical presentation and course shared "a striking resemblance" to MIS-C. The patient improved after treatment with anticoagulation, intravenous immunoglobulin, and tocilizumab.

"We emphasize the importance of multidisciplinary care and recognition of the possibility of this syndrome across specialties, as provision of care for our patient necessitated coordinated efforts between specialists in emergency medicine, internal medicine, infectious diseases, cardiology, rheumatology, dermatology, and ophthalmology," wrote Dr. Alisa Fernia and colleagues.

"Pediatricians are well aware of Kawasaki disease and its clinical signs. However, internists in general have not seen this symptom complex and so many not recognize it," said Dr. Jane Burns, director of the Kawasaki Disease Research Center at the University of California, San Diego.

Typically, the disease is seen in young children because the triggers for Kawasaki disease are widespread and create a response early in life, Dr. Burns said. For some adults, though, it seems the body's immune response to COVID-19 can provoke a similar immune response.

Dr. Burns wasn't involved with the current case report, but said she is reviewing several others involving both children and adults for medical journals.

"I suspect there are more of these cases out there that are being missed," she told Reuters Health by email. "The heart may be a target of inflammation and needs to be imaged, so it is important to recognize this newly emerging syndrome."
