Granulomatosis With Polyangiitis : Disease Understanding

GPA Overview

Granulomatosis With Polyangiitis (GPA, formerly known as Wegener’s granulomatosis) is an autoimmune small-vessel vasculitis that is highly associated with anti-neutrophil cytoplasmic antibodies (ANCA). According to the Chapel Hill criteria (2012), GPA is defined as necrotizing granulomatous inflammation usually involving the upper and lower respiratory tract, and necrotizing vasculitis affecting predominantly small-to-medium vessels (e.g., capillaries, venules, arterioles, arteries, and veins).

The disease was initially described by Klinger in 1931 as a variant of polyarteritis nodosa and was defined for the first time as a separated syndrome by Friedrich Wegener. Godman and Churg (1954) introduced the term ‘Wegener’s granulomatosis’ and further delineated the clinical and pathological features.

Two phenotypes are distinguished in GPA that are localized and systemic with the possible transition during disease. Typically, patients initially suffer from a limited form that may consist of constitutional symptoms and localized manifestations, such as chronic sinusitis, rhinitis, otitis media, ocular conditions, and/or skin lesions. More serious manifestations may arise in later stages, including pulmonary complications and glomerulonephritis, although the skin, eyes, and heart may also be involved. Classically, the acronym ELK is used to describe the clinical involvement of the ear, nose, and throat (ENT), lungs, and kidneys.

The etiology of GPA is linked to environmental and infectious triggers inciting disease onset in genetically predisposed individuals. Anti-neutrophil cytoplasmic antibodies are pathogenic and play an important role in the pathogenesis of this disease. Pathological processes involved include aberrant epigenetic expression of proteinase-3 on the cell membrane of neutrophils and the formation of antibodies against proteinase-3 (PR3-ANCA). The binding of PR3-ANCA to PR3 activates neutrophils, and there is a release of neutrophilic inflammatory mediators, the formation of neutrophil extracellular traps that lead to complement activation and damage to endothelial cells of small blood vessels.

Diagnosis of GPA is achieved through clinical assessment, serological tests for anti-neutrophil cytoplasmic antibodies (ANCA), and histological analysis. Biopsy, imaging, and laboratory tests are involved. Symptoms of microscopic polyangiitis (MPA), eosinophilic Granulomatosis With Polyangiitis (EGPA), Goodpasture syndrome (GPS), polyarteritis nodosa (PAN), lymphomatous granulomatosis (LyG), and systemic rheumatological disorders can be similar to those of GPA for which differential diagnosis is useful.

The treatment of GPA involves Induction therapy as the first phase, which aims to quickly put the disease into remission and lasts about 3–6 months according to the clinical response, and maintenance therapy as the second phase that lasts 12–24 months to consolidate the remission and limit the risk of relapse. The standard therapy for GPA is a combination of glucocorticoids and cyclophosphamide/ rituximab. Adjuvant therapy and plasma exchange are also involved.

The early diagnosis and specific treatment of GPA are important but difficult to achieve because of the multiplicity of presenting symptoms and unclear histological features. Talking about the pathogenesis of GPA, it has undergone many advances and progressed over the years. Hopefully, this will be translated into the development of new and better therapies for patients.
