Background
Antineutrophil cytoplasmic antibody-associated vasculitis is dominated by inflammatory occlusion of small vessels, causing tissue ischemia in various organs. This disorder has rarely been associated with vasculopathy, such as antiphospholipid syndrome.
Case presentation
We report a case of a 48-year-old Persian male presenting with distal digital gangrene along with inflammatory arthralgia. High titers of anti-proteinase 3 and antiphospholipid antibodies (anticardiolipin antibody) were detected in laboratory evaluation. Therefore, a diagnosis of antineutrophil cytoplasmic antibody-associated vasculitis and antiphospholipid syndrome was made and treated with anticoagulant along with monthly pulses of cyclophosphamide and a daily dose of 1 mg/kg prednisolone.
Conclusion
Our case, along with other reports, illustrates that these two entities can coexist. Therefore, monitoring antiphospholipid antibodies in patients with antineutrophil cytoplasmic antibody-associated vasculitis with or without clinical evidence of any thrombosis and ruling out thrombosis in cases that do not respond to proper treatment of vasculitis may be relevant to prevent irreversible or fatal organ damage.
