Visual Representation | AIRD Rates Rise Post-COVID-19

United States: The concerns regarding COVID-19 have been increasing across the world. Recently, research has concluded that rates regarding autoimmune inflammatory rheumatic disease (AIRD), such as rheumatoid arthritis and systemic lupus erythematosus, have increased in South Korea and Japan. Following this research, the local health authorities of the United States have raised concerns as the levels of COVID-19 are high across the nation.

What does the new study reveal?

According to the stats shared by MD, Ph.D. of Kyung Kee University in Seoul – Dong Keon Yon, among the patients of COVID-19, AIRD rates were 25 percent higher in South Korea and 79 percent in Japan. Along with this, Absolute rates after COVID were 1.15 percent and 3.87 percent in Korea and Japan, respectively.

Vaccination and reduced development of AIRD!

As per the reports by researchers in the Annals of Internal Medicine, vaccination against the SARS-CoV-2 virus contributes to reduced chances of developing AIRD.

The rise in risk wasn’t just because COVID-19 patients were in touch with majority of healthcare facilities, leading to more observation. The researchers made sure to compare COVID-19 patients with those treated for the flu. The chances of AIRD (acute incident respiratory disease) were noticeably higher in the COVID groups – 30 percent more in the Korean data and 14 percent more in Japan, the newly conducted study revealed.

Other studies backing the facts concluded by recent research!

According to the reports, other studies have also found that the risk of rheumatologic disease rates increases following COVID-19 infection, according to MedPage Today.

But those studies didn’t consider the possibility of biased information gathering, as Yon and colleagues did. Another drawback of the previously conducted studies was they didn’t explore how vaccinations might affect the outcomes.

However, the latest study emphasized that the new analysis used a case-control design. In the Korean national data, there were around 394,000 people with confirmed COVID-19 infections. Yon and colleagues picked about 177,000 for comparison; each was matched with four uninfected (neither COVID nor influenza) individuals from the general population, making a total of 676,000 controls.

The comparison between COVID-19 and flu patients involved 95,000 people in each group. The matching considered various health-related and sociodemographic factors at the beginning. In the Japanese cohorts, there were 961,000 COVID-19 patients compared with 1.6 million uninfected people; for COVID versus influenza, the group sizes were 115,000 and 110,000, respectively.

According to the reports MedPage Today, vaccination status also played a crucial role in determining the data reported by the study. In addition to this, the severity of the infection was also established through measures such as admission to intensive care and extracorporeal membrane oxygenation.

To collect the data, Yon and colleagues worked in two categories to identify AIRD cases. Reportedly, the categories are inflammatory arthritis, comprising rheumatoid and psoriatic arthritis and spondyloarthritis, and connective tissue diseases, which include lupus, Sjögren’s syndrome, systemic sclerosis, polymyalgia rheumatica, mixed connective tissue disease, dermatomyositis, polymyositis, polyarteritis nodosa, and vasculitis.
