Core Tip

Core Tip: Previously, we demonstrated that the first wave of coronavirus disease 2019 (COVID-19) pandemic caused exacerbation in ulcerative colitis (UC) patients. Impact of the successive waves of the pandemic is of interest. We adopted the identical group of patients who were included in our previous study indicating the impact of the first wave in 2020. Disease activity of UC patients, aggravated by the stress of the first wave of COVID-19 in 2020, recovered significantly in 2021 and remained stable in 2022, despite persistence of the pandemic.
