Summary

POEMS syndrome, a rare disorder, involves elevated vascular endothelial growth factor (VEGF). Ticlopidine significantly reduced VEGF levels in a patient, suggesting its potential as a supportive therapy for this condition.

Area of Science:

  • Hematology
  • Neurology
  • Endocrinology

Background:

  • POEMS syndrome is a rare multisystem disorder characterized by polyneuropathy, organomegaly, endocrinopathy, M-proteins, and skin changes.
  • Elevated levels of vascular endothelial growth factor (VEGF) have been increasingly associated with POEMS syndrome.

Observation:

  • This report details a case of POEMS syndrome presenting with markedly high VEGF titers.
  • Initial treatments including steroids, plasmapheresis, and intravenous immunoglobulin showed minimal efficacy.
  • Several immunosuppressive agents were discontinued due to adverse effects.

Findings:

  • While aspirin administration did not impact VEGF levels, ticlopidine treatment resulted in a significant decrease in VEGF titers.
  • This observation highlights a potential therapeutic role for ticlopidine in managing VEGF levels in POEMS syndrome.

Implications:

  • Ticlopidine emerges as a potential supportive therapy for POEMS syndrome, specifically targeting elevated VEGF.
  • Monitoring VEGF levels before and after ticlopidine administration is recommended for further validation in clinical practice.
