ABSTRACT
INTRODUCTION: This study aims to collect data on the vaccination status of Myasthenia Gravis (MG) patients, assess the coverage of vaccines, and examine MG exacerbations.
METHODS: We conducted a retrospectively observational study including patients diagnosed with MG between 2015 and 2023 with antibodies against acetylcholine receptors.
RESULTS: Eighty-nine patients were analysed. Forty-one (46.1%) were women. The median age at onset was 68 years. The median follow-up was 3.9 years. Sixteen (17.9%) patients had early-onset MG and 32 (36.0%) had ocular MG. Fifty-four (60.7%) patients received pneumococcal vaccines. Seventy-five (84.3%) patients received one dose of the seasonal influenza vaccine. Ten patients (76.9%) received hepatitis A virus (HAV) vaccination, and 33 (64.7%) received four doses of the hepatitis B virus (HBV) vaccine. One and six patients were classified as non-responders for HAV and HBV vaccines, respectively. Two patients were vaccinated with the live attenuated varicella-zoster virus vaccine. No differences were found between vaccination in early versus late-onset MG. No MG exacerbations were observed following vaccination.
DISCUSSION: It is mandatory to establish recommendations for vaccination to ensure timely and appropriate immunisation.
