Background The acute phase of adult IgA vasculitis (IgAV) is well characterized. Data of even short-term prognosis of adult IgAV is scarce, mostly retrospective and usually limited to patients with significant renal disease.
Objectives Our aim was to examine the short-term prognosis in a cohort of unselected adult IgAV cases.
Methods We analysed medical records of newly diagnosed, histologically proven cases of IgAV at our department of rheumatology between 1 January 2010 and 30 June 2015, that were followed until 31 December 2015.
Results We identified 139 IgAV cases during the observation period. The clinical characteristics at presentation and the initial treatment are shown in Table 1. During the acute phase of the disease 3/139 patients died (2 due to active vasculitis, 1 due to generalized CMV infection and heart failure). Twenty patients were lost to follow-up. The clinical characteristics of the remaining 116 patients who were followed for a median 8.9 (IQR 5.5 – 22.7) months at follow-up are shown in Table 2. During the follow-up new malignancy was diagnosed in 6/116 (5.2%) patients and 8/116 (6.9%) patients died. All deaths were due to causes unrelated to IgAV.
Conclusions Contrary to the experience in children, IgAV in adults does not seem to be a benign disease even in the short-term. Admittedly, it is impossible to conclude whether this is due to the nature of the adult IgAV or because adults have more comorbidities than children.
