CIDP and hemopathies, an underestimated association

Area of Science:

• Neurology
• Hematology
• Pathology

Background:

• Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated disorder.
• CIDP can be associated with systemic conditions, including hemopathies (blood disorders).
• Neurological complications may arise in patients with hemopathies.

Purpose of the Study:

• To describe clinical, electrophysiological, and pathological data of patients with concurrent CIDP and hemopathy.
• To highlight the importance of considering CIDP in patients with peripheral neuropathy and hemopathy.
• To emphasize the treatable nature of CIDP and potential for positive clinical response.

Main Methods:

• Retrospective analysis of 21 patients with CIDP and hemopathy.
• Inclusion of patients meeting EAN/PNS electrodiagnostic criteria for CIDP (2021).
• Nerve biopsy performed for pathological confirmation in all patients.

Main Results:

• All patients fulfilled diagnostic criteria for CIDP.
• Pathological nerve biopsy findings were consistent with CIDP.
• No evidence of direct hematological complication affecting the peripheral nervous system was found.

Conclusions:

• CIDP should be considered in patients presenting with peripheral neuropathy and hemopathy, especially malignant types.
• Nerve biopsy confirmation is valuable in diagnosing CIDP in this context.
• Multidisciplinary collaboration (neurology, hematology, oncology) is crucial for optimal patient management.
