Maintaining remission in a patient with vasculitis.

Area of Science:

• Rheumatology
• Immunology
• Internal Medicine

Background:

• A 40-year-old male diagnosed with Wegener's granulomatosis (WG) presented with multi-system involvement including skin, ENT, pulmonary hemorrhage, and renal disease.
• Initial remission was achieved with plasma exchange, prednisolone, and cyclophosphamide, but the patient experienced relapses despite maintenance therapy with azathioprine and mycophenolate mofetil.

Observation:

• The patient exhibited refractory WG despite multiple treatment regimens, including cyclophosphamide, azathioprine, and mycophenolate mofetil.
• Disease progression involved eyes, upper and lower respiratory tracts, and kidneys, necessitating comprehensive investigations.
• Intercurrent infections complicated management, requiring aggressive antibiotic treatment alongside immunosuppressants.

Findings:

• Deoxyspergualin and oral steroids controlled disease activity, but relapses occurred upon discontinuation.
• Pulsed intravenous cyclophosphamide was used for breakthrough relapses.
• Rituximab ultimately achieved remission in this refractory WG case.

Implications:

• This case underscores the challenges in managing refractory Wegener's granulomatosis.
• Rituximab offers a promising therapeutic option for patients with treatment-resistant WG.
• Multidisciplinary care and vigilant monitoring are crucial for optimizing outcomes in complex vasculitis cases.
