ABSTRACT
BACKGROUND: The pathogenesis of angioedema induced by angiotensin-converting enzyme inhibitors is based on the accumulation of bradykinin as a result of angiotensin-converting enzyme blockade. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to the angiotensin-converting enzyme 2 receptor, which may inhibit its production and thereby lead to an increase in bradykinin levels. Thus, SARS-CoV-2 infection may be a likely trigger for the development of angioedema. AIMS: This study aimed to analyze cases of hospitalizations of patients with angioedema associated with the use of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers during the coronavirus disease 2019 (COVID-19) pandemic. MATERIALS AND METHODS: This study retrospectively analyzed medical records of patients admitted to the Vitebsk Regional Clinical Hospital between May 2020 and December 2020 with isolated (without urticaria) angioedema while receiving angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. In all patients, smears from the naso and oropharynx for COVID-19 were analyzed by polymerase chain reaction. RESULT(S): Fifteen inpatients (9 men and 6 women) aged 44-72 years were admitted because of emergent events, of which 53.6% had isolated angioedema. In two cases, a concomitant diagnosis of mild COVID-19 infection was established with predominant symptoms of angioedema, including edema localized in the face, tongue, sublingual area, and soft palate. All patients had favorable disease outcomes. CONCLUSION(S): Patients with angiotensin-converting enzyme inhibitor-induced angioedema may require hospitalization to monitor upper respiratory tract patency. There were cases of a combination of angiotensin-converting enzyme inhibitor-induced angioedema and mild COVID-19. Issues requiring additional research include the effect of SARS- CoV-2 infection on the levels of bradykinin and its metabolites, the triggering role of COVID-19 in the development of angioedema in patients receiving angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, recommendations for the management of patients with angiotensin-converting enzyme inhibitor-induced angioedema, and a positive result for COVID-19.Copyright © 2020 Pharmarus Print Media All rights reserved.
ABSTRACT
Regardless of the COVID-19 pandemic in 2020, discovering a new salivary gland turned into all the rage among the medical fraternity. The significance of the disclosure has been correlated with its clinical relevance in radiotherapy of oropharyngeal carcinoma. However, there are views against this new revelation, owing to the lack of substantial evidence. We have endeavoured to illuminate Tubarial glands with potential shreds of evidence.
