ANCA-associated vasculitis: the focus is on eosinophilic granulomatosis with polyangiitis (eosinophilic vasculitis of Charge-Strauss)

Eosinophilic granulomatosis with polyangiitis (Charge-Strauss syndrome) is an eosinophilic granulomatous disease characterized by small caliber vascular lesions and is autoimmune in nature. Patients with this syndrome experience weight loss, fever, arthralgias, and myalgias. The disease most often begins with respiratory tract involvement, including infectious allergic rhinitis, bronchial asthma, symmetric eosinophilic pulmonary infiltrates, and eosinophilic pneumonia. In older individuals, the syndrome manifests with multiple mononeuritis, asymmetric polyneuropathy, anemia, and muscle weakness. This scientific review presents the main aspects of the prevalence, mechanisms of development, spectrum of clinical manifestations, diagnosis and differential diagnosis of eosinophilic granulomatosis with polyangiitis.
