January 6, 2022 – Multisystem inflammatory syndrome in children (MIS-C) is more common than previously thought. This childhood disease occurs 2 to six weeks after infection with COVID-19.
For every 100 COVID-19 hospitalizations, there have been 17 MIS-C hospitalizations, a brand new study The disease is rare but causes dangerous multiple organ failure and sometimes requires intensive care. According to the CDC, there have been a minimum of 9,333 cases and 76 deaths nationwide from MIS-C.
The researchers said their findings were so at odds with previous MIS-C studies that they potentially made the old studies “misleading.”
The evaluation, published Thursday by JAMA Network Open, was based on improved data from hospital billing systems. Previous analyses by MIS-C were limited to voluntarily reported cases, which is probably going the explanation for the underreporting.
The study reported a mortality rate of 5.8% in essentially the most severe cases (with 6 to eight organs). The authors of a Accompanying editorial staff According to the study, the mortality rate is low given the far-reaching effects, reflecting “the rapid reversibility of MIS-C” through treatment.
Differences in MIS-C cases were also found based on the race and ethnicity of the kids. Black patients were more prone to have severe cases involving more organs in comparison with white patients.
The study included 4,107 MIS-C cases and used 2021 data for patients under 21 years of age. The average age was 9 years.
The results point the best way for further research, the editorial authors suggested.
Among the questions that must be answered is why black children with MIS-C usually tend to have a bigger variety of affected organ systems.
“Attempts should be made to identify patient biological or socioeconomic factors that can be specifically treated or prevented,” they wrote.
The CDC says Symptoms of MIS-C are persistent fever and greater than one among the next symptoms:
- Stomach pain
- Bloodshot eyes
- Diarrhea
- Dizziness or lightheadedness (signs of low blood pressure)
