POEMS syndrome: clinical update

Area of Science:

• Neurology
• Oncology
• Immunology

Background:

• POEMS syndrome is a rare paraneoplastic syndrome linked to plasma cell disorders.
• It presents with polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes.
• The neurological hallmark is a subacute, disabling demyelinating neuropathy.

Purpose of the Study:

• To review the clinical features of POEMS syndrome.
• To discuss differential diagnoses for POEMS syndrome.
• To outline current treatment options for POEMS syndrome.

Main Methods:

• Literature review of clinical features, diagnosis, and treatment of POEMS syndrome.
• Analysis of the role of vascular endothelial growth factor (VEGF) in POEMS syndrome.
• Discussion of current understanding of POEMS syndrome pathogenesis.

Main Results:

• POEMS syndrome diagnosis requires a specific neuropathy and other systemic features.
• Elevated VEGF levels are useful for diagnosis and monitoring treatment response.
• Despite high VEGF, treatments targeting it have yielded disappointing results.

Conclusions:

• POEMS syndrome is a complex disorder with diverse clinical manifestations.
• VEGF plays a role but does not solely drive the disease, suggesting other mechanisms are involved.
• Further research into pathogenesis and novel therapeutic targets is warranted.
