Autonomic Nervous System Dysfunction in Primary Sjögren's Syndrome

Area of Science:

• Immunology
• Neurology
• Rheumatology

Background:

• Primary Sjögren's syndrome (pSS) is an autoimmune disorder affecting exocrine glands and potentially the nervous system.
• Autonomic nervous system (ANS) dysfunction is frequently observed in pSS patients, contributing to significant symptom burden and fatigue.
• Emerging evidence highlights the interplay between the ANS and immune system via the vagus nerve.

Purpose of the Study:

• To explore the role of ANS dysfunction in Primary Sjögren's syndrome.
• To investigate the potential of vagus nerve stimulation (VNS) as a therapeutic strategy for pSS, especially for fatigue management.

Main Methods:

• Review of existing studies on ANS dysfunction in pSS.
• Analysis of the relationship between the ANS, immune system, and vagus nerve.
• Examination of VNS effects on fatigue in pSS patients.

Main Results:

• ANS dysfunction is prevalent in pSS and correlates with disease features like fatigue.
• Vagus nerve stimulation has demonstrated potential benefits in alleviating fatigue among pSS patients.
• The ANS represents a promising therapeutic target for pSS management.

Conclusions:

• The autonomic nervous system is a potential treatment target for Primary Sjögren's syndrome, particularly for managing fatigue.
• Further research is needed to elucidate the ANS-immune system link in pSS and validate VNS as a therapy.
