RESUMEN
OBJECTIVES: Plasmapheresis (PLEX) and intravenous immunoglobulin (IVIg) are commonly used to treat autoimmune neuromuscular disorders, including myasthenia gravis, acute inflammatory demyelinating polyradiculoneuropathy, chronic inflammatory demyelinating polyradiculoneuropathy, and other autoimmune neurological disorders. The side effect profiles of these therapies vary, and concern has been raised regarding the safety of PLEX in the elderly population. In this study, we have examined the pattern of PLEX and IVIg use for autoimmune neurological disorders at a single facility and in a national database, focusing on the complications in elderly patients. METHODS: We performed a retrospective chart review of adult patients at our institution receiving PLEX or IVIg for any autoimmune neuromuscular or neuro-immunological disease. Next, we analyzed the National Inpatient Sample database to confirm the trend in IVIg and PLEX use from 2012 to 2018 for a set of neuromuscular and neuro-immunological primary diagnoses. RESULTS: IVIg was overall favored over PLEX. The adverse effects were similar among elderly patients (age ≥65 years) compared with younger patients (<65 years) in our institution, even after adequate matching of patients based on age, sex, and medical history. We examined the National Inpatient Sample dataset and noted increasingly higher frequency of IVIg use, consistent with the findings from our institution or facility. CONCLUSIONS: Both PLEX and IVIg are safe therapeutic choices in adult patients with autoimmune neuromuscular disorders and other neuro-immunological diseases and can be safely administered in the appropriate clinical setting.

IMPORTANCE: Vaccines are a safe and efficacious way to prevent a variety of infectious diseases. Over the course of their existence, vaccines have prevented immeasurable morbidity and mortality in humans. Typical symptoms of systemic immune activation are common after vaccines and may include local soreness, myalgias, nausea, and malaise. In the vast majority of cases, the severity of the infectious disease outweighs the risk of mild adverse reactions to vaccines. Rarely, vaccines may be associated with neurological sequela that ranges in severity from headache to transverse myelitis, acute disseminated encephalomyelitis, and Guillain-Barre syndrome (GBS). Often, a causal link cannot be confirmed, and it remains unclear if disease onset is directly related to a recent vaccination. OBSERVATIONS: This review serves to summarize reported neurologic sequelae of commonly used vaccines. It will also serve to discuss potential pathogenesis. It is important to note that many adverse events or reactions to vaccines are self-reported into databases, and causal proof cannot be obtained. CONCLUSIONS AND RELEVANCE: Recognition of reported adverse effects of vaccines plays an important role in public health and education. Early identification of these symptoms can allow for rapid diagnosis and potential treatment. Vaccines are a safe option for prevention of infectious diseases.
