Multiple Sclerosis and Autoimmune Comorbidities

Area of Science:

• Neurology
• Immunology
• Chronic Disease Management

Background:

• Multiple sclerosis (MS) is a heterogeneous neuroinflammatory and neurodegenerative condition.
• Multisystem comorbidities, particularly autoimmune diseases, are common in people with MS (PwMS).
• These comorbidities can significantly influence MS pathogenesis, diagnosis, disease activity, and patient prognosis.

Purpose of the Study:

• To review the incidence and prevalence of autoimmune diseases in PwMS.
• To explore the effects of autoimmune comorbidities on the clinical and neuroradiological course of MS.
• To analyze the impact of autoimmune conditions on treatment choices for MS.

Main Methods:

• Systematic literature review of existing studies.
• Analysis of data on autoimmune disease prevalence in MS populations.
• Evaluation of studies examining the clinical and radiological outcomes in PwMS with autoimmune comorbidities.

Main Results:

• Data on the precise incidence and prevalence of specific autoimmune diseases in PwMS is variable.
• Autoimmune comorbidities are associated with altered MS disease activity, progression, and brain atrophy.
• The presence of autoimmune conditions can necessitate modifications in MS treatment strategies.

Conclusions:

• Autoimmune comorbidities represent a critical factor influencing the multifaceted nature of MS.
• Understanding these associations is vital for personalized treatment and improved management of PwMS.
• Further investigation is warranted to fully elucidate the mechanisms and clinical implications of autoimmune comorbidities in MS.
