ABSTRACT
INTRODUCTION: SARS-CoV-2 pandemic is especially compromising for patients with autoimmune diseases with or without immunomodulatory treatment. This study aimed to investigate the longitudinal changes in the health care of patients with immune-mediated neuropathies during the COVID-19 pandemic. METHODS: We performed a longitudinal study using questionnaires in a prospective cohort of patients with immune-mediated neuropathies at two timepoints of the pandemic: May-July 2021 and May-July 2022. RESULTS: The cohort consisted of 73 patients (55 male), mean age 62 years, 68 patients with CIDP, 5 with other immune neuropathies. In 2021, 19.2% of the patients reported a reduced number of physician-patient-contacts, while 13.7% reported this in 2022. Nevertheless, the overall health-care situation worsened from 2021 to 2022: 15.1% reported reduced overall healthcare in 2021, 26.0% in 2022. In 2021, 29.4% of patients reported absence of physio-/occupational therapy, while 34.4% reported this in 2022. Switching immunomodulatory treatment and stretching of treatment intervals occurred more often in 2022 (38.4%) than in 2021 (27.4%). 12 COVID-19-infections occurred overall, with typical only mild symptoms. The rate of fully vaccinated patients was 61.6% and 98.6% in May-July 2021 and 2022, respectively. Only minor side-effects after vaccination were reported. CONCLUSION: Despite mitigation of COVID-19 restrictions from 2021 to 2022, the health-care situation of patients worsened in this time. Reasons could be the international shortage of immunoglobulins during the pandemic and reduced physio/ergotherapy due to lingering regulatory restrictions. Vaccination rate was high in our cohort of patients compared to the general German population and CIDP did not seem to be a risk factor for severe SARS-CoV-2 infections.
