Dermatologic comorbidities of the patients with severe COVID-19: A case-control study.

ABSTRACT

The current studies focus on the association between COVID-19 and certain comorbidities. To the best of our knowledge, the association between severe COVID-19 and dermatologic comorbidities has not been reported yet. In this study, we aimed to describe the dermatologic comorbidities of patients with severe COVID-19 and compare it with the control group. Patients who have died at Usak Training and Research Hospital due to COVID-19 and other diseases in the COVID-19 Intensive Care Units and Internal Medicine Intensive Care Units were recruited into the study. Two groups were compared with each other regarding the most common dermatologic comorbidities. A total of 198 patients including 111 patients with COVID-19 and 87 age and sex-matched patients with other diseases were enrolled in the study. The most common dermatologic comorbidities were pruritus (8.1%), eczema (6.3%), skin infections (3.6%), leukocytoclastic vasculitis (1.8%), and urticaria (0.9%) in the COVID-19 group while they were skin infections (9.2%), eczema (3.4%), pruritus (2.3%), and urticaria (1.1%) in the control group. None of patients in the control group had leukocytoclastic vasculitis. There were no significant differences between COVID-19 and control groups in terms of pruritus, eczema, skin infections, and urticaria (P values were .117, .517, .181, .505, and 1.000, respectively). In conclusion, although it is not statistically significant, it appears that pruritus and leukocytoclastic vasculitis are more common in severe COVID-19 patients. These cytokines-related diseases in the immuno-cutaneous systems may give some clues on the COVID-19 severity. Further studies are required to elucidate the relationship between the immuno-cutaneous system and COVID-19 severity.
