High Levels of Autoantibodies Against Catalase and Superoxide Dismutase in Nasopharyngeal Carcinoma

Introduction:Autoantibodies against the antioxidant enzymes have been described in Epstein-Barr virus-associated diseases. Here, we hypothesize that Epstein-Barr virus (EBV), which is associated with nasopharyngeal carcinoma (NPC), induces anticatalase and/or antisuperoxide dismutase autoantibodies that inhibit catalase and/or superoxide dismutase activities and thereby contribute to the oxidative stress status described in this…

Extensive workup for alternate etiologies was negative and while serologies specific for SS were unremarkable, the diagnosis was eventually suggested by excisional biopsy. This case highlights the difficulty in…
