Refractory rheumatoid vasculitis.

Area of Science:

• Rheumatology
• Immunology
• Neurology

Background:

• Systemic rheumatoid vasculitis (SRV) is a rare but severe complication of long-standing rheumatoid arthritis with high disease activity.
• It commonly presents as cutaneous vasculitis or mononeuritis multiplex, but can involve any organ system, leading to high mortality.

Observation:

• A young male with 15 years of rheumatoid arthritis, refractory to standard and anti-TNF therapies, developed SRV.
• The condition manifested as mononeuritis multiplex, progressing to gangrene of extremities despite cyclophosphamide treatment.
• Further complications included critical care neuromyopathy, central nervous system vasculitis, and testicular involvement, unresponsive to IV immunoglobulin and rituximab.

Findings:

• This case demonstrates a rare, chronic, and protracted presentation of SRV.
• The vasculitis involved the skin, peripheral nerves, central nervous system, and testes.
• The patient's condition was refractory to multiple recommended immunosuppressive and biologic therapies.

Implications:

• This case underscores the potential for severe, multi-organ SRV even with aggressive treatment.
• It highlights the challenges in managing treatment-refractory SRV and the need for exploring alternative therapeutic strategies.
• Understanding rare presentations of SRV is crucial for improving patient outcomes and managing this life-threatening condition.
