TI  - [A CASE OF ANAPHYLAXIS CAUSED BY LANDLOCKED AYU FISH, KOAYU FISH, FROM LAKE 
      BIWA].

AB  - A 28-year-old man was transferred to our emergency room for dyspnea and wheals on 
      the entire body. He had eaten landlocked ayu fish (Plecoglossus altivelis) the 
      so-called "koayu fish", from Lake Biwa, and had immediately experienced a 
      stomachache. Wheals and dyspnea developed one hour later and were successfully 
      treated with intravenous corticosteroids. The patient was examined for koayu fish 
      and related allergens by skin prick and allergen-specific immunoglobulin E (IgE) 
      (ImmunoCAP((R))) tests. Positive skin prick results were obtained for Lake Biwa 
      koayu fish (raw and heated) as well as for standard skin test allergens (prepared 
      by Torii pharmaceuticals) including shrimp, crab, and squid. Negative prick test 
      results were observed for regular ayu fish and other fish such as horse mackerel, 
      sardine, salmon, mackerel, codfish, and tuna. Allergen-specific IgE tests 
      (ImmunoCAP ((R))) showed positivity for shrimp, crab, ticks, moths, and mosquitoes, 
      while ImmunoCAP((R)) tests were negative for the allergen components rGad c 1 
      (pollackparvalbumin) and rPen a 1 (shrimp tropomyosin). Moreover, enzyme-linked 
      immunosorbent assay (ELISA) tests were negative for mackerel parvalbumin and 
      collagen. We considered this case to be of anaphylaxis caused by koayu fish from 
      Lake Biwa and speculated that a novel koayu-specific antigen might have been the 
      cause of the condition.
