[Peripheral nerve involvement in rheumatic diseases].

Area of Science:

• Neurology
• Rheumatology

Background:

• Peripheral neuropathies are an under-diagnosed complication of rheumatic diseases.
• These neuropathies can range from mild to severe, significantly impacting patient quality of life.

Purpose of the Study:

• To emphasize the importance of precise diagnosis and etiological classification for successful treatment and prognosis of peripheral neuropathies in rheumatic diseases.

Main Methods:

• Detailed patient history and physical examination form the basis of diagnosis.
• Electrophysiological studies are mandatory for suspected peripheral neuropathy.
• Nerve or nerve-muscle biopsies are reserved for specific cases.

Main Results:

• Therapeutic approaches for these neuropathies often lack robust evidence.
• Treatment commonly involves immunosuppressive therapies for the underlying rheumatic disease (e.g., glucocorticoids, cyclophosphamide, IVIg).
• Symptomatic pain management utilizes medications like gabapentin, pregabalin, duloxetine, venlafaxine, and TCAs.

Conclusions:

• Accurate diagnosis and classification are vital for managing peripheral neuropathies in rheumatic diseases.
• Treatment strategies combine addressing the underlying condition with symptomatic pain relief.
• Further evidence is needed to optimize therapeutic approaches.
