Treatment of primary erythema nodosum when prior systemic therapies have not resolved recalcitrant pretibial nodules

In a subset of patients with primary erythema nodosum, recurrent or recalcitrant erythematous nodules on the pretibial area persist despite a full course of standard systemic management. When the goals of that earlier treatment line have not been achieved, a defined escalation pathway applies.

The preceding line of therapy may have included agents such as:

  • Dapsone
  • Hydroxychloroquine
  • Minocycline or tetracycline
  • Erythromycin
  • Prednisone (for severe disease)
  • Intralesional triamcinolone acetonide (for recalcitrant nodules)
The stated goal of that line — resolution of recurrent or recalcitrant erythematous nodules on the pretibial area — was not reached. This protocol addresses the next step.
Next-line treatment direction

This protocol involves biologic therapy from the TNF-α inhibitor class. The specific agents, sequencing, and complete dosing algorithm are contained in the full structured regimen.

Tumor necrosis factor-α inhibitors such as etanercept, adalimumab, and infliximab have been used in patients with recalcitrant disease.
