58% of IBD biologic patients with positive covid19 serology had no symptoms

An interesting one, they checked blood serology for IBD patients on biologics to check for exposure to covid19 (presence of Antibodies against covid19). 58 percent who had been exposed had zero symptoms.

Asymptomatic Severe Acute Respiratory Syndrome Coronavirus 2 Infection in Patients With Inflammatory Bowel Disease Under Biologic Treatment

"More than half (58%) of patients with positive SARS-CoV-2 serology results were completely asymptomatic during LD, and the others reported only mild symptoms. All biologic treatments were safely administered, even at high doses for the induction of remission. In this cohort, immunosuppressive treatment did not affect SARS-CoV-2 infection outcome.

Preliminary data suggest that immunosuppression is not an additional risk factor for the development of severe forms of SARS-CoV-2 infection, because it was also shown for the previous coronaviruses pandemics, SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome).4"

Seems our outcomes (all IBD patients regardless of meds) is better overall. We also have a lower mortality rate, even after adjusting for age (as IBD patients tend to be young). We're not invincible, there are mortalities and hospitizations. But I generally feel better than I did initially in March.

With only a 19 patient sample size, this could easily just be a fluke and mean nothing. Will be interesting to see larger, more significant studies.

Haha, that's a fun tool! The way it varies with country shows all the biases, namely it depends on the rate at which a country performs covid tests and uploads the ibd patients data onto the website
