Summary

The current state of knowledge on ANCA-associated vasculitis (AAV) indicates that it is a group of autoimmune diseases in which small blood vessels in various organs are affected. Disease entities included in this group are granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss syndrome).

These are rare diseases, with an incidence in Europe of approximately 20-25 cases per million people per year. There is a slight predominance among men, and the risk of developing the disease increases with age.

ANCA antibodies play a role in the pathogenesis of the disease, and inflammation within small vessels leads to damage of the vessel walls, resulting either in rupture or occlusion of the vessel lumen. Consequently, vital organs such as the kidneys, lungs, heart, nervous system, upper respiratory tract, gastrointestinal tract, and eyes may be affected.

If the disease is not diagnosed, untreated, or treated improperly, it can lead to irreversible failure of these organs and even death. Despite appropriate treatment, AAV diseases tend to relapse; therefore, therapy consists of two phases: induction therapy and maintenance therapy.

Current EULAR/EDTA guidelines for induction treatment of AAV recommend the use of cyclophosphamide (CYC) or rituximab (RTX) in combination with glucocorticosteroids in cases of severe disease. If remission is achieved after induction therapy, maintenance treatment should be initiated with drugs such as azathioprine, mycophenolate mofetil, methotrexate, or rituximab, combined with a low dose of glucocorticosteroids. Maintenance therapy should last no less than two years.

The study will focus on ophthalmological evaluation of patients diagnosed with ANCA-associated vasculitis. In this disease, all structures of the eye may be involved. The most common ocular manifestations include scleritis, keratitis, proptosis, inflammation of orbital tissues, nasolacrimal duct obstruction, and orbital involvement leading to proptosis, double vision, and restricted eye movement.

Until recently, the disease was often fatal. However, advances in diagnostics and current pharmacological treatment options, combined with appropriately aggressive immunosuppressive therapy, have significantly improved survival, enhanced patients' quality of life, and reduced mortality. Early diagnosis and prompt initiation of appropriate therapy are crucial.
