Sensory neuronopathy and autoimmune diseases.

Area of Science:

• Neurology
• Immunology
• Peripheral Nervous System Disorders

Background:

• Sensory neuronopathies (SNs) are characterized by the degeneration of dorsal root ganglia and their projections.
• Multifocal sensory symptoms and ataxia are hallmark clinical features of SNs.
• Immune-mediated damage is a primary cause of SNs, often preceding systemic autoimmune diseases.

Purpose of the Study:

• To review clinical, neurophysiological, and therapeutic data on autoimmune disease-related SNs.
• To highlight the importance of recognizing SNs in clinical practice due to their association with systemic autoimmunity.

Main Methods:

• Systematic review of existing literature.
• Analysis of clinical presentations, neurophysiological findings, and treatment outcomes.
• Focus on SNs associated with Sjögren's syndrome, autoimmune hepatitis, and celiac disease.

Main Results:

• Immune-mediated damage is a significant factor in the pathogenesis of SNs.
• SNs can serve as an early indicator of underlying systemic autoimmune conditions.
• Specific data on autoimmune-related SNs in Sjögren's syndrome, autoimmune hepatitis, and celiac disease were compiled.

Conclusions:

• Autoimmune processes are central to the development of many sensory neuronopathies.
• Early identification of SNs is vital for diagnosing and managing associated systemic autoimmune diseases.
• Further research into the clinical, neurophysiological, and therapeutic aspects of autoimmune SNs is warranted.
