Fever following Covid-19 vaccination in subjects with Brugada syndrome: Incidence and management.

BACKGROUND: Fever is a potential side effect of the Covid-19 vaccination. Patients with Brugada syndrome (BrS) have an increased risk of life-threatening arrhythmias when experiencing fever. Prompt treatment with antipyretic drugs is suggested in these patients. AIM OF THE STUDY: To evaluate the incidence and management of fever within 48 h from Covid-19 vaccination among BrS patients. METHODS: One hundred sixty-three consecutive patients were enrolled in a prospective registry involving five European hospitals with a dedicated inherited disease ambulatory. RESULTS: The mean age was 50 ± 14 years and 121 (75%) patients were male. Prevalence of Brugada electrocardiogram (ECG) pattern type-1, -2, and -3 was 32%, 44%, and 24%, respectively. Twenty-eight (17%) patients had an implantable cardioverter-defibrillator (ICD). Fever occurred in 32 (19%) BrS patients after 16 ± 10 h from vaccination, with a peak of body temperature of 37.9° ± 0.5°. Patients with fever were younger (39 ± 13 vs. 48 ± 13 years, p = .04). No additional differences in terms of sex and cardiovascular risk factors were found between patients with fever and not. Twenty-seven (84%) out of 32 patients experienced mild fever and five (16%) moderate fever. Pharmacological treatment with antipyretic drugs was required in 18 (56%) out of 32 patients and was associated with the resolution of symptoms. No patient required hospital admission and no arrhythmic episode was recorded in patients with ICD within 48 h after vaccination. No induced type 1 BrS ECG pattern and new ECG features were found among patients with moderate fever. CONCLUSION: Fever is a common side effect in BrS patients after the Covid-19 vaccination. Careful evaluation of body temperature and prompt treatment with antipyretic drugs may be needed.

Incidence and management of adverse events among COVID-19 vaccination receipts with Brugada syndrome. Results from a multicentre-prospective European registry

Aims Patients with Brugada syndrome have an increased risk of life-threatening arrhythmias when experience fever. Therefore, a prompt treatment of non-steroidal anti-inflammatory drugs (NSAI) is suggested in these patients. COVID-19 vaccination can be associated with fever in about 20% of patients. The aim of the study is to evaluate the incidence and management of adverse events within 48 h from COVID-19 vaccination among Brugada patients. Methods and results Eighty patients were enrolled from a prospective registry involving four European hospitals with a dedicated inherited disease ambulatory. Cardiological follow-up was performed within one month from vaccination. Mean age was 47 ± 17 years, 80% (num = 63) were male. Prevalence of Brugada types 1, 2, and 3 was as follows: 25% type 1, 39% type 2, and 24% type 3. Twenty-six percent of patients had an implantable cardioverter defibrillator (ICD). Within in 48 h from vaccination, 35% (num = 28) of patients experienced joint paint, 19% (num = 15) fever and 4% (num = 3) chest pain. In 8 out of 15 fever episodes body temperature was ≥38 degrees and treated with NSAI drugs. No patients had syncope or fatigue episodes and no arrhythmic episodes were recorded in patients with ICD. Conclusions About 20% of patients experienced fever after Covid-19 vaccination but no patient experienced life-threatening arrhythmias. Careful evaluation of body temperature and administration of NSAI in case of temperature higher than 38 is suggested.
