RESUMO
The coronavirus vaccine was developed to help overcome the COVID-19 crisis. This study aimed to identify the cutaneous side effects secondary to Pfizer-BioNTech and Oxford-AstraZeneca COVID-19 vaccines in the general population of Saudi Arabia and to list the risk factors for the development of cutaneous side effects. This cross-sectional study was conducted in 2021, self-administered surveys were distributed electronically through social media, and telephonic interviews were conducted with a sample size of 1000 participants. Data analysis was performed using Statistical Package for the Social Sciences. A total of 1021 patients (229 male and 722 female) aged 12 years or older were included. While 833 participants were medically free, 188 had chronic illnesses. While 802 participants were not taking any medications, 219 were taking medications regularly. Oxford-Astra Zeneca and Pfizer BioNTech vaccines were administered to 319 and 702 participants, respectively. One-hundred and twenty-five participants previously had COVID-19 infection and 407 were exposed to a PCR positive case of COVID. Six hundred and fifty-nine patients (64.5%) reported experiencing injection site reactions: 606 (59.4%) had injection site pain, 168 (16.5%) had injection site swelling, and 107 (10.5%) had injection site redness. Only 51 patients (5%) experienced cutaneous side effects after injection. A significant association was found between chronic illnesses and cutaneous side effects post-vaccine (9% vs. 4.1%; p value = 0.005). Patients on medications showed a higher rate of symptoms (8.2% vs. 4.1%; p value = 0.005). Age, gender, vaccine types, and history of COVID-19 infection were not significantly associated with cutaneous side effects post-vaccine.

BACKGROUND: The introduction of biological treatments has revolutionized the management of moderate-to-severe psoriasis. Multiple clinical trials have established the efficacy of biological agents in the treatment of moderate-to-severe psoriasis. Nevertheless, there are no clear indications for optimal monitoring intervals during treatment. OBJECTIVES: Collect and analyze laboratory evaluation data from patients receiving biological therapy to provide a better understanding of the need for laboratory investigations before and during treatment with biological agents, and to analyze adverse events and other factors. DESIGN: Retrospective cohort SETTINGS: Tertiary care center in Riyadh, Saudi Arabia. PATIENTS AND METHODS: Data were collected from the electronic medical records of patients attending the dermatology, rheumatology, and gastroenterology clinics from June 2014 to June 2019. The laboratory parameters of patients who have received one of the TNF-alpha inhibitors (adalimumab, etanercept, or infliximab) were collected starting at baseline and up to at least one year from treatment initiation. MAIN OUTCOME MEASURES: The time points at which patients developed significantly abnormal laboratory results during treatment with one of the TNF-alpha inhibitors. SAMPLE SIZE: 250 patients RESULTS: Most patients were treated with adalimumab (38.4%); a similar proportion (38%) with infliximab, whereas only 23.6% were treated with etanercept. The majority of the significant abnormal laboratory results occurred at baseline, 3-6 and 9-12 months. Most abnormalities were among patients using infliximab, followed by etanercept, and then adalimumab. The median number of laboratory abnormalities for dermatology patients was significantly lower than that for gastroenterology patients (P<.001), and for rheumatology patients (P=.002). CONCLUSIONS: Because dermatology patients showed a lower median number of laboratory abnormalities than patients treated by other specialties in our study, we believe that dermatology patients require less frequent laboratory monitoring. Therefore, we recommend laboratory evaluation at baseline, after 3-6 months, 1 year from the beginning of treatment, and annually thereafter for patients using TNF-alpha inhibitor agents. However, more frequent testing might be warranted according to patient comorbidities, concomitant medications, and physician judgment. LIMITATIONS: Single center and retrospective design. CONFLICT OF INTEREST: None.
