Towards a reassessment of certain contraindications to the use of drugs in autoimmune myasthenia gravis
American researchers have investigated the possible complications associated with the use of several classes of antibiotics known to be harmful to myasthenia gravis patients: data from patients followed between 2002 and 2022 in Cleveland (USA) and taking ciprofloxacin, levofloxacin (both fluoroquinolones) or azithromycin, were analysed retrospectively. The main endpoint was the occurrence of decompensation of … [Read more]
