Superfície ocular e hepatite C

Abstract: RESUMOObjetivos: Avaliar os resultados dos testes utilizados para o diagnóstico de olho seco em portadores do vírus da hepatite C, e verificar se há relação entre a duração conhecida da doença e a intensidade das alterações da superfície ocular. Métodos: Foram avaliados 25 pacientes portadores do vírus da hepatite C não tratados e 29 indivíduos com testes sorológicos negativos para hepatite C. Nos dois grupos, foi realizada a mesma sequência de exames: biomicroscopia, teste de cristalização da lágrima, tempo d… Show more

“…Recently, 2 studies conducted in Brazil also emphasized the predominance of ocular surface alterations. Gomes et al detected ocular surface disease in at least 1 eye in 88% of infected patients, exhibiting alterations in assessment parameters such as rose bengal staining (a vital dye that evaluates live epithelial cells without tear film protection) and the BUT test, in addition to observing altered stoichiometry (a test that evaluates corneal sensitivity) and less sensory perception in the eyes of infected patients (43) . In a study of 138 infected patients versus controls, Zeni et al found altered BUT and Schirmer test results and observed higher mean tonometry values in the infected group (44) .…”

“…The pathogenesis of dry eye in patients with HCV in fection involves the destruction of glandular cells, possibly by antigenic reactions to immunocomplexes produced by viral antigens and specific antibodies or by the direct action of the virus (32,42) . Other possibilities suggest that lymphocytic infiltration of the lacrimal gland (45,46) or modification of corneal sensitivity occurs due to sensory alterations in the trigeminal nerve, reducing tear production (43) .…”

“…Ocular manifestations such as retinopathy, scleritis and keratitis have been well documented (35) . Cacoub et al evaluating a group of 312 HCV patients found xerostomia and/or xeroftalmia symptoms in 10% (36) which makes the ocular surface one of the most important sites of manifestations in HCV infected patients (37) . Both entities, Sjögren syndrome and HCV, are characterized by B-cell hyperactivity although related to different etiologies, autoimmune and infectious respectively.…”
