Ankylosing Spondylitis (AS) is the prototype of the axial form of spondyloarthritis. Despite extensive studies, complex mechanisms related to abnormal cellular and molecular processes in AS are not completely understood.Among proinflammatory mediators such as proinflammatory cytokines, chemokines, which lead to inflammation, matrix metalloproteinases (MMPs)
Granulomatosis with polyangiitis (GPA) is a type of small-sized blood vessel vasculitis that predominantly affects the upper airways, lungs and kidneys and associates with the presence of anti-neutrophil cytoplasmic antibodies (ANCA). Nevertheless, any organ of the body can be affected by GPA, including the eye. Occasionally, ocular involvement can be the initial manifestation, thus representing an essential clue for the physician in the early diagnosis of the disease.
We present the case of a 53-year-old woman in whom recurrent episcleritis was the first sign of a multisystem disease. All further investigations led to the final diagnosis of GPA. The remission induction therapy chosen by the rheumatologist consisted of intravenous cyclophosphamide (CP) and methylprednisolone pulse-therapy, followed by oral glucocorticoids (GC). Based on the favorable clinical and paraclinical evolution, induction therapy was replaced by remission maintenance therapy. Azathioprine (AZA) was initiated and oral GC were continued, with dose tapering. Complete remission of episcleritis was observed.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
