IgA Vasculitis is a leukocytoclastic vasculitis involving small vessels with depositions of immune complexes containing IgA. IgA Vasculitis is a predominantly pediatric vasculitis. There is limited data for the prognosis of adult IgA Vasculitis, with also no damage assessment. In this study, we aimed to evaluate the clinical characteristics, treatment, outcome and damage of patients with adult IgA Vasculitis.
We assembled a retrospective cohort of patients with adult IgA Vasculitis from tertiary Rheumatology Centers in Turkey. The demographics, clinical characteristics, treatment and outcomes of patients were abstracted from medical records. Birmingham Vasculitis Activity Score (BVAS), prognostic Five Factor Score (FFS) and vasculitis damage index (VDI) were calculated.
The study included 103 (male/ female: 67/36) patients with adult IgA Vasculitis. The mean age was 42.6±17 years. Infection history within 6 weeks before presentation was present in 40 (38.8%) patients (32 upper respiratory tract, 3 urinary tract, 2 gastrointestinal, 3 others). Cutaneous manifestations and arthritis/arthralgia were the most common clinical manifestations (Table 1). Ninety-two (89.3%) patients were treated with oral glucocorticoids (GC). Pulse GC treatment was also given to 29 (28.1%) patients. As additional immunosuppressive agents, azathiopirine was given to 36 (34.9%) and pulse cyclophosphamide to 13 (12.6%) patients. Fifty-nine patients (58.2%) had follow-up of mean 35.6 months. Eleven (18.6%) patients relapsed during follow-up. While 5 relapses were major, six of them were minor relapses. At the last visit, disease status was evaluated as active or treatment failure by the treating physician in 7 (11.8 %) patients. The rate of chronic renal failure was 8.3 %(n=5). Mortality was 1.6% (n=1) during follow-up, due to pneumonia. The mean VDI score was 0.3 in the last visit. Twelve (20.3%) patients had at least one damage item at the end of follow-up period.
Our results showed that approximately one fifth of patients with adult IgA Vasculitis had relapses during follow-up and had at least one damage item at the end of follow-up, Although, 31% of patients had FFS≥1, the mortality rate was observed to be very low in the present study.
