Respiratory muscle weakness in peripheral neuropathies.

Area of Science:

• Neurology
• Pulmonology
• Clinical Medicine

Background:

• Peripheral neuropathies typically spare diaphragmatic function and respiratory capacity.
• Respiratory compromise is a significant concern in Guillain-Barré syndrome (GBS).
• Limited diaphragmatic weakness occurs in chronic inflammatory demyelinating polyneuropathy and multifocal motor neuropathy.

Purpose of the Study:

• To review respiratory involvement in peripheral neuropathies.
• To highlight the management of respiratory compromise in Guillain-Barré syndrome.
• To discuss the applicability of GBS management protocols to other peripheral neuropathies.

Main Methods:

• Literature review focusing on respiratory complications in peripheral neuropathies.
• Analysis of Guillain-Barré syndrome management strategies.
• Discussion of specific neuropathies like Charcot-Marie-Tooth disease subtypes.

Main Results:

• Diaphragmatic weakness is uncommon in most peripheral neuropathies, except for specific Charcot-Marie-Tooth (CMT) subtypes (CMT2C, CMT4B1).
• Electrophysiologic findings correlate with respiratory compromise primarily through phrenic nerve response amplitudes.
• Standardized respiratory management approaches developed for GBS are applicable to other peripheral neuropathies.

Conclusions:

• Frequent respiratory function assessment is crucial for patients with peripheral neuropathies.
• Established mechanical ventilation criteria for GBS can be adapted for other neuropathies.
• Proactive respiratory management is essential for patients with peripheral neuropathies and respiratory compromise.
