Increased autophagy accelerates colchicine-induced muscle toxicity.

OBJECTIVE

Celiac disease (CD) is an autoimmune disorder, characterized by increased susceptibility to bacterial and viral infections. Therefore, the CD patients could be exposed to an increased risk of contracting SARS-CoV-2, a virus for which the WHO declared a pandemic status in March 2020. This study aims to investigate the incidence of SARS-CoV-2 infection in CD patients, to assess the impact of CD on the risk of contracting this virus.

PATIENTS AND

METHODS

This retrospective multicentric cohort study evaluated 542 celiac patients, who answered a questionnaire concerning both the underlying disease (adherence to the gluten-free diet, residual symptoms) and the possible SARS-CoV-2 infection (swab outcome, presence and characteristics of symptoms and type of treatment received), referring to the period between 20th January 2020 and 27th October 2020.

RESULTS

Five patients (0.92%) tested positive; of these, 2 were asymptomatic and 3 developed symptoms of COVID-19. The incidence of SARS-CoV-2 infection in CD patients was not significantly different from the general population. The ratio of positive/diagnostic swabs tends to be higher in CD patients than in the general population (IR: 0.15; 0.06; p=0.06), whereas the number of subjects who performed the swab in this group is significantly lower (IR: 0.06; 0.15; p<0.001).

CONCLUSIONS

Although CD patients are more susceptible to infections, the incidence of SARS-CoV-2 infection in our sample was not significantly different from the general population. However, the positive/diagnostic swabs ratio seems to be higher, probably also due to the lower number of patients tested.
