Sputnik-V vaccine-induced panniculitis as a local reactions.

Here, a case of Sputnik-V vaccine-induced panniculitis was reported. The patient developed erythema, induration, and local tenderness at the injection site after 13 days of the injection. Ultra-sonography imaging showed inflammation in subcutaneous layers including fat tissue compatible with panniculitis. She received ibuprofen and warm compress, and all symptoms resolved.

Evaluation of the prophylactic effect of hydroxychloroquine on people in close-contact with patients with COVID-19.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has caused significant mortality worldwide. The disease attacks the lung tissue and may lead to acute respiratory distress syndrome. An in vitro study showed that hydroxychloroquine (HCQ) has a prophylactic effect against COVID-19 due to its anti-inflammatory effects. The present study aimed to evaluate the prophylactic effect of HCQ on individuals in close contact with patients with COVID-19. METHOD: In this quasi-trial study, we prescribed HCQ for 7 days to all people who had close contact with a patient with COVID-19. All contacts underwent a nasal swab in two steps, and those positive for COVID-19 were excluded from the study. After 14 days of follow-up, the clinical and laboratory manifestations of COVID-19 were evaluated. RESULTS: A total of 113 participants completed the study. The HCQ group comprised 51 (45.13%) contacts, and 62 (54.86%) contacts were allocated to the control group. According to the results of clinical examination and real-time polymerase chain reaction test, 8 (12.90%) contacts in the control group were reported to have contracted COVID-19. In the HCQ group, 7 (13.72%) contacts were confirmed to have contracted COVID-19. There was no relationship between HCQ use and age, sex, underlying disorders, and laboratory data (all p > 0.05). In terms of HCQ side effects, five participants experienced gastrointestinal and cutaneous side effects that subsided on discontinuation of HCQ. CONCLUSION: The current study showed that HCQ had no prophylactic effect with regard to COVID-19 prevention.

Evaluating the elimination status of medications used for COVID-19 during hemoperfusion and therapeutic plasma exchange: A review.

Since late 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, better known as COVID-19) has rapidly spread worldwide. The primary pathophysiology by which COVID-19 leads to severe lung damage is cytokine releasing syndrome (CRS), which can cause death. Therefore, removing cytokines via therapeutic plasma exchange or hemoperfusion could be a therapeutic approach to treat CRS. However, hemoperfusion or therapeutic plasma exchange could alter the effectiveness of concomitant medications. Thus, concomitant medication doses might need to be adjusted to prevent their elimination via therapeutic plasma exchange or hemoperfusion, thus ensuring that these medications remain effective. This narrative review investigates the elimination status of current medications used to manage COVID-19 during hemoperfusion and therapeutic plasma exchange, with a focus on their pharmacokinetic profiles.
