COVID vaccination reduces the danger of type 2 diabetes after infection

February 14, 2023 – Vaccination appears to scale back the increased risk of developing type 2 diabetes after a COVID infection, in accordance with a study. new study Published in JAMA network opened.

Early within the pandemic, individuals who had recovered from COVID infection were more more likely to develop diseases similar to diabetes for the primary time. This study confirmed those observations and located that the upper risk endured throughout the pandemic, whilst latest variants emerged.

“Our findings confirm that the risk of developing type 2 diabetes after COVID-19 infection was not just an early observation, but indeed a real risk that unfortunately persists throughout the omicron era,” said lead creator Alan Kwan, MD, a cardiologist on the Smidt Heart Institute at Cedars-Sinai, in an announcement.

Kwan notes that the trend is concerning because most individuals within the U.S. have already been infected with COVID or shall be infected with COVID sooner or later. At the identical time, he and his co-authors found that the danger of developing diabetes was higher in unvaccinated people than in vaccinated people, suggesting that vaccination reduces the danger.

“This research study helps us understand and better prepare for the post-COVID period of cardiovascular risk,” he says.

Kwan and colleagues analyzed medical records of nearly 24,000 adult patients who had a minimum of one confirmed COVID infection and were treated at Cedars-Sinai Health System in Los Angeles between March 2020 and June 2022. They looked for brand new cardiometabolic diagnoses (diabetes, hypertension and high lipid levels similar to cholesterol) reported before or after a patient's first COVID infection.

The research team estimated the probability of one among these cases occurring 90 days after infection in comparison with 90 days before infection.

To account for disruptions in healthcare utilization in the course of the pandemic, they compared their results to the likelihood of one other latest diagnosis unrelated to the COVID visit, similar to a urinary tract infection or acid reflux disease. They also considered aspects similar to age, gender, timing of infection (before or after the emergence of the omicron variant of COVID-19), and whether the patient had received the COVID vaccine.

Overall, rates of new-onset diabetes, hypertension, and high lipids were higher within the 90 days after COVID infection than before. Diabetes had the best probability of being diagnosed after infection, followed by hypertension.

Further analyses showed that the danger of developing latest type 2 diabetes after a COVID infection remained elevated.

The combined risk – for each vaccinated and unvaccinated patients – was 2.1%, with 70% occurring after COVID infection and 30% occurring before COVID exposure.

In unvaccinated patients, the danger was 2.7%, with 74% developing the disease after COVID infection in comparison with 26% before contact with COVID.

In vaccinated patients, the danger was 1%, with 51% occurring after COVID infection in comparison with 49% before COVID contact.

“These results suggest that COVID-19 vaccination prior to infection may have a protective effect against diabetes risk,” says Kwan. “Although further studies are needed to confirm this hypothesis, we remain firmly convinced that COVID-19 vaccination remains an important tool for protection against COVID-19 and the still-unclear risks people may face in the post-infection period.”

The research team found no differences in increased risk based on age, gender, or timing of infection (before or after Omicron). However, some questions remain about other aspects, similar to the severity of COVID infection, the newest variants, and the variety of vaccine doses.

Further research can be needed to grasp how COVID affects the body and diabetes risk, the authors indicate. Persistent inflammation, a trademark of COVID infection, can result in insulin resistance, metabolic disorders, and the event of hypertension or diabetes. Due to damaged blood vessels and organs, these latest developments also increase the danger of heart attacks and strokes.

“Although we don't yet know for sure, the trends and patterns we see in the data suggest that in certain situations, COVID-19 infection could act as a disease accelerator, increasing the risk of a diagnosis that people would otherwise have received later in life,” said lead creator Susan Cheng, MD, professor of cardiology and director of the Division of Cardiovascular Population Sciences on the Smidt Heart Institute, in an announcement.

“It could be that a person who is already at risk for diabetes after a COVID-19 infection will not be diagnosed with diabetes at age 65, but rather develop diabetes at age 45 or 55,” she says.
