Two patients with IgA nephropathy and a patient with Henoch-Schönlein purpura nephritis each associated with anterior uveitis are described. As anterior uveitis accompanying IgA nephropathy improved, renal manifestations were relieved. The patient with Henoch-Schönlein purpura nephritis suffered from not only anterior uveitis but also keratitis. It is suggested that immune mechanisms which induce IgA nephropathy may play a role in the development of anterior uveitis and keratitis.
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.
