Evaluation of the alopecia areata patients on tofacitinib treatment during the COVID-19 pandemic.

Tofacitinib is a Janus Kinase 3 inhibitor that is used in the treatment of alopecia areata. We recommended our alopecia areata patients to discontinue their tofacitinib treatment during the COVID-19 pandemic for an average of 80 days. We aimed to evaluate the drug use and the SARS-CoV-2 infection status of alopecia areata patients; and the relationships of recurrence to age, gender, treatment duration, and tofacitinib discontinuation. One-hundred and ninety-one (61.4%) patients were off the drug and 120 (38.6%) were on therapy during the pandemic. The relationship between drug discontinuation due to the COVID-19 pandemic and recurrence was statistically significant (P < .001). Statistically significant relationships of age (P = .013) and treatment duration (P < .001) to recurrence were also found. The change in the SALT score differed between the patients on therapy and off therapy during the pandemic (P < .001). A significant negative correlation was found between the change in the SALT score and treatment duration: the spearman correlation test P = .018. We concluded that the patients may continue to the tofacitinib therapy during the rest of the COVID-19 pandemic if the benefit outweighed the risk.

The impact of COVID-19 in patients with psoriasis: A multicenter study in Istanbul.

There is widespread concern about treatment of psoriasis in COVID-19 pandemic. We aimed to evaluate the epidemiological data, clinical characteristics, treatment features of the psoriasis patients during the pandemic period. We conducted a study in dermatology clinics of seven different tertiary centers. All adult psoriasis patients who were followed up between 11 March 2020 and 28 June 2020, were phone called or questioned in their visit to their follow-up clinics. A semistructured questionnaire was applied and patients' demographics and disease characteristics were recorded. Of 1322 patients, 52.4% were male, and 47.6% were female. According to the questionnaire responses, 964 (72.9%) of these patients could not communicate with their physician during this period, remained 358 (27.1%) patients contacted the physician by phone, email, or hospital visit. From the patients diagnosed as probable/confirmed COVID-19, 14 were female, and 9 were male. Nine of 23 (39.1%) patients were using biologic treatment. There was no statistically significant difference in terms of hospitalization from COVID-19 between the patients using biologics (n = 9) and those who did not (n = 14) (P = 1.00). No mortality was observed among them. Obesity, smoking, age, and accompanying psoriatic arthritis were not among the risk factors affecting the frequency of COVID-19. We only encountered an increased risk in diabetic patients. Also, an exacerbation of psoriasis was observed with the infection. No difference was found in patients with psoriasis in terms of COVID-19 infection in patients who use biologics and those who don't.

Can rituximab be used in the treatment of pemphigus vulgaris during the COVID-19 pandemic?

Rituximab is a monoclonal antibody that targets CD20, a B-lymphocyte antigen; that leads to a decline in the B-cell counts for at least a year. The patients who have received rituximab treatment in the previous 5 years with the diagnosis of pemphigus group of diseases at Cerrahpasa Medical Faculty were questioned for COVID-19 infection. A total of 48 patients were included in this study; only one male patient had COVID-19 infection which had a mild course. There is no significant difference in the total number of lymphocytes between patients who have received rituximab within the previous 5 years or last year. The number of lymphocytes is independent of the number of courses of rituximab treatment received. Therefore, we suggest that all pemphigus patients who have received rituximab treatment within the previous 5 years should be careful of the preventive measures against the COVID-19 infection irrespective of the number of treatment courses or the number of years which has passed since the treatment. The disease course was mild in the only infected patient. Thus, rituximab may be used in the treatment of pemphigus vulgaris during the COVID-19 pandemic if its use is necessary.

Cutaneous manifestations in hospitalized patients diagnosed as COVID-19.

Cutaneous manifestations of COVID-19 disease have not yet been fully described. To describe cutaneous manifestations of COVID-19 disease in hospitalized patients. We examined the cutaneous manifestations of 210 hospitalized patients. Cutaneous findings were observed during COVID-19 infection in 52 of the patients. Lesions may be classified as erythematous scaly rash (32.7%), maculopapular rash (23%), urticarial lesions (13.5%), petechial purpuric rash (7.7%), necrosis (7.7%), enanthema and apthous stomatitis (5.8%), vesicular rash (5.8%), pernio (1.9%), and pruritus (1.9%). Cutaneous manifestations were observed statistically significantly more in certain age groups: patients of 55 to 64 and 65 to 74 years of age complained of more cutaneous manifestations than the other age groups. As for gender, there was no significant difference between male and female patients in terms of cutaneus findings. The relationship between comorbidity and dermatological finding status was statistically significant. The relationship increases linearly according to the comorbidities. According to the statistical results, the patients who were hospitalized in the intensive care unit had a higher risk of having cutaneous findings due to COVID-19 infection. With this study, we may highlight the importance of overlooked dermatological findings in patients that are hospitalized.

Inpatient dermatology consultations during COVID 19 pandemic in a tertiary referral center.

Since the COVID-19 infection first appeared in December 2019, patient profile of outpatient and inpatient clinics has changed. Various cutaneous findings associated with COVID-19 have been reported in the literature. The main objective of this study was to describe and analyze the profile of the consultations requested from dermatology department during the COVID pandemic. Retrospective, cohort study. In this study, we observed the dermatology consultations of the hospitalized patients over a period of 2 months, corresponding to the peak of COVID outbreak in a tertiary care hospital in Turkey. We reviewed the inpatient dermatology consult database retrospectively. Both pediatric and adult dermatology inpatient consultations were evaluated. A total of 166 inpatient dermatology consultations were requested from dermatology department during March-May, 2020. The mean age of the patients was 53.12 (1-89) years. Almost 32.5% (n = 54) of dermatology consultations were requested from the COVID wards and the COVID intensive care unit. The second most common consultations were requested from internal medicine departments (n = 46, 27.7%). The most common indications for the consultations were cutaneous infections (36%), followed by inflammatory disorders (32%), and urticaria (11%). Dermatology consultations have an essential role on the management of hospitalized patients, especially at that pandemic time. Careful dermatological examination improves diagnostic accuracy in skin disorders and skin manifestations of COVID-19 infection that provides an early diagnosis and treatment, helps to improve the quality of the patient care and management.
