Eosinophilic granulomatosis with polyangiitis (Churg-Strauss) induced by immune checkpoint inhibitors

Abstract: Figure 1 Timeline showing the relationship between serum eosinophil count and treatment with immune checkpoint inhibitors (double arrow: nivolumab 1 mg/kg and ipilimumab 3 mg/kg infusions; single arrow: nivolumab 3 mg/kg infusion).

“…Increased AEC, serum IL-6, Il-10 and IgE levels were associated with corticosteroid-refractory adverse events and with grade 3 or greater cutaneous AEs, but the direct accountability of eosinophils was not assessed in these exceptional cases. 24 Even if some severe cutaneous AEs like drug reaction with eosinophilia and systemic symptoms (DRESS) require high-dose corticosteroids, 25,26 multiple recent reports of Eo-irAEs like eosinophilic fasciitis [27][28][29][30] or eosinophilic granulomatosis with polyangiitis 31 suggest that topical or low-dose oral corticosteroids, with or without CSsparing treatments, can give excellent results. Taking account these data, and given that in our work (i) Eo-ir and Eo-irAEs accounted for half of all ICI discontinuations and (ii) no deaths were directly attributable to eosinophil-organ damage, we suggest that the initiation of corticosteroids and the maintenance of the ICI might be an effective therapeutic strategy in patients with moderate-to-severe eosinophilia and whose cancer is under control.…”

“…Various forms of vasculitis affecting large vessels have been reported, and the corresponding diagnoses include GCA [33,56,57] or periaortitis [58]. Additionally, medium or small vessels can be affected, with cases of granulomatosis with polyangiitis (GPA) [59,60], eosinophilic granulomatosis with polyangiitis (EGPA) [61] and cryoglobulinemic vasculitis [62] having been reported. Cutaneous granulomatous [63,64] and leukocytoclastic vasculitides [65] have also been described.…”

“…Tyrosine kinase inhibitors (TKIs) such as axitinib, pazopanib, sorafenib, regorafenib, and sunitinib, as well as interferons, sirolimus, bisphosphonates (pamidronate and zoledronic acid) can induce FSGS. Cytotoxic T-lymphocyte-associated antigen (CTLA)-4 inhibitors such as ipilimumab, can induce MCD or lupus-like glomerular nephritis [26,27]. Other kidney manifestations in patients receiving checkpoint inhibitors (CPIs) are lupus nephropathy, pauci-immune glomerular nephritis, immunoglobulin A (IgA) nephropathy, as well as nephrotic syndrome with FSGS, MCD, and membrane nephropathy [28].…”
