Introduction: The basis of the development of the anti-interleukin-5 monoclonal antibody mepolizumab was the acknowledgment of the crucial importance of this cytokine in promoting eosinophils production, activation, and survival, which is associated with the eosinophilic asthma phenotype, as well as with other disorders characterized by high levels of eosinophils. Areas covered: All the available literature on the outcomes treatment with mepolizumab in eosinophilic disorders are reviewed, including asthma, chronic rhinosinusitis, esophagitis, granulomatosis with polyangiitis, eosinophilic chronic obstructive pulmonary disease, hypereosinophilic syndrome, and allergic bronchopulmonary aspergillosis. ⋯ Among other eosinophilic disorders, controlled trials are available for chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, hypereosinophilic syndrome, eosinophilic granulomatosis with polyangiitis, and eosinophilic chronic obstructive pulmonary disease. Allergic bronchopulmonary aspergillosis, as well as other minor eosinophilic disorders, are backed only by case reports and are waiting controlled trials to verify the therapeutic role of mepolizumab.

ReviewTreatment of systemic necrotizing vasculitides: recent advances and important clinical considerations.
Introduction: Primary systemic necrotizing vasculitides (SNVs) include polyarteritis nodosa, Kawasaki disease, ANCA-associated vasculitides, IgA vasculitis, and cryoglobulinemic vasculitis. All are rare but potentially severe, life-threatening conditions. Evidence-based treatments are well established, but continue to evolve and management requires some expertise. ⋯ Results from ongoing and future trials for vasculitis will likely impact these treatment approaches. Entirely avoiding GC may become possible, perhaps even the next gold standard, if medications such as avacopan are confirmed to be safe and effective. New combination strategies, more individualized for each patient, may also prove to be more effective, faster.
