Effectiveness and safety of intravenous immunoglobulin for peripheral neuropathy in EGPA patients: a retrospective study
摘要
Eosinophilic granulomatosis with polyangiitis (EGPA) is a chronic inflammatory disease belonging to the spectrum of small-vessel vasculitis associated with the presence of anti-neutrophil cytoplasmic antibodies (ANCAs), also characterized by eosinophilic infiltration of target organs. Peripheral neuropathy (PN) affects about 2/3 of the patients as a presenting symptom and typically represents a vasculitic involvement. A few studies have addressed the role of intravenous immunoglobulin (IVIg) for the treatment of PN in EGPA. This monocentric retrospective study aims at assessing the effectiveness and safety of IVIg in patients with PN as the main acute manifestation at EGPA onset. The treatment with IVIg appears to be effective in inducing sustained remission, reducing the risk of relapses and improving the long-term disability due to its effects on PN.
