Abstract
IntroductionIt is known that the administration of the drug during the oral aspirin challenge (OAC) can cause hypersensitivity symptoms not only from the respiratory system or skin, but also from the cardiovascular system.AimTo assess the occurrence and nature of cardiovascular adverse events during the OAC in patients suspected of hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs).Material and methodsThe study included 52 patients with symptoms of hypersensitivity to aspirin (ASA) or other NSAIDs in the form of skin reactions or respiratory response in anamnesis. Patients were treated with OAC and simultaneously were subject to monitoring of clinical manifestations of hypersensitivity to ASA/NSAIDs, ventilation disorders and cardiovascular functions.ResultsThe most common reaction of the cardiovascular system during OAC was tachycardia or supraventricular and ventricular extrasystoles, regardless of the day of the study and the result of OAC. Supraventricular and ventricular tachycardia was recorded incidentally. Atrial or ventricular fibrillation or flutter was not observed. There was no evidence of any ischemic heart disease. In 2 patients, hypotension was registered, but only 1 of them required typical treatment of anaphylaxis.ConclusionsNo clinically significant cardiac arrhythmias were recorded during OAC. The changes observed in the records of blood pressure and ECG monitoring show that OAC performed in accordance with the current guidelines does not pose a high risk to the patient’s health and life as a result of cardiovascular reactions.
