Summary

Cutaneous vasculitis is a rare adverse reaction to granulocyte colony-stimulating factor (G-CSF). This condition typically occurs in patients with chronic benign neutropenias and can be managed by adjusting G-CSF dosage or using topical steroids.

Area of Science:

  • Hematology
  • Dermatology
  • Pharmacology

Background:

  • Cutaneous vasculitis has been anecdotally reported in patients receiving granulocyte colony-stimulating factor (G-CSF).
  • Further investigation is warranted to understand the prevalence and characteristics of this adverse drug reaction.

Purpose of the Study:

  • To determine the prevalence of cutaneous vasculitis in patients undergoing G-CSF therapy.
  • To establish a causal relationship between G-CSF and cutaneous vasculitis.
  • To explore potential pathomechanisms underlying this adverse event.

Main Methods:

  • Comprehensive literature review.
  • Analysis of case data from the G-CSF manufacturer's safety database.
  • Global assessment of drug causality for adverse reactions.

Main Results:

  • Eighteen cases of cutaneous vasculitis were identified, with only three previously published.
  • Leukocytoclastic vasculitis was confirmed via skin biopsy in 12 patients.
  • While rare in neutropenia associated with malignancy, vasculitis occurred in 6% of patients with chronic benign neutropenias, correlating with increased absolute neutrophil count (ANC).

Conclusions:

  • Cutaneous vasculitis is an adverse reaction to G-CSF with low morbidity.
  • Management involves dose reduction or discontinuation of G-CSF and topical steroid treatment.
  • Recurrence was prevented by maintaining ANC below 800/mm³.
