Covid-19 would increase the risk of developing type 1 diabetes

Although we know the pathophysiology of type 1 diabetes and its autoimmune nature relatively well, research has great difficulty in identifying the causes that determine this disease. The viral hypothesis has often been raised with virus infections such as herpes. Recently, a new cohort study was presented at an academic conference in Sweden by Norwegian researchers. Using national health registries, they studied the risk of developing type 1 diabetes in youth under the age of 18 positive for Covid-19 between March 2020 and March 2022. In addition to the end of the study, follow-up ended when the adolescent reached the majority of age or unfortunately died as a result of the infection.

Previous data

a report of Central Disease Center, in the United States, suggested in early 2022 that after SARS-CoV-2 infection, children were 2.5 times more likely to be diagnosed with diabetes. However, the studies leading to this observation take into account the two types of diabetes and do not take into account crucial confounding factors such as general health, medication use, ethnicity, diagnosis ofobesity or social determinants. Therefore, it was difficult to reach a firm conclusion based on these figures.

The Norwegian study: a risk still low but 60% higher

Comparing children and adolescents who received a positive diagnosis of Covid-19 (424,354) and those who did not receive such a diagnosis or tested negative (775,646), the researchers suggest that there is an increased risk of type 1 diabetes of 60%. which increases from 0.08% to 0.13% after a positive diagnosis of Covid-19 in young people under 18 years of age. Important confounding factors were taken into account in the statistical analysis of the study, which makes the results more robust. On the other hand, it is not known whether the severity of symptoms or…
