鉤虫症に発現したメニエル氏症候群

　1．緒言

　鉤虫症の顕著な症状としては貧血，消化器障碍及び神経症状が挙げられている。この神経症状のうち眩暈，耳鳴，難聴は可成り主要な発現頻度を占め，その他の症状もメニエル氏病の場合に呈する症状と共通した点が少くないようである。而るに鉤虫症の場合に発現する斯かるメニエル氏症候群とも云うべきものについての詳細な報告は未だ無いようである。メニエル氏症候を呈する患者にその原因を探究し適確な治療を行うべきである事は言を俟たないが，その原因を探究する事は困難な場合が多く徒らに種々の対症療法を試みているのが現状であり治療効果の不良な所以も此処にあるように考えられる。私は最近メニエル氏症候群を呈して外来を訪れた患者に鉤虫の寄生を認め駆虫に依つて症状を好転せしめ得た2例を経験したので此処に報告し御参考に供する次第である。

TANAKA notes his observations on sympto-ms of Menierre's syndrome found in patients who were hosts to infestation of ancylostoma as follows: 1) Of the two patients observed both showed classical symptoms of Menierre's syndrome wi-th hearing impairement and vertigo besides the inherent anemia. After effective deworming was established the hearing improved with re-covery from vertigo though anemia was not completelly overcome.

2) In one case the condition found may be considered as that of an allergy because of the decrease in the amount of calcium in the blood and spinal fluid, defficient state of vitamin B1 and eosinophilia. But, due to presence of vago-tony in the picture it might be termed as an atypical form rather than a true allergy.

3) Menierre's syndromes that may be mani-fested concurrently with infestations of intesti-nal parasite may be considered as an affection closely related to allergy the result of toxic products emanated by the parasites acting as allergens. Consequently the author maintains that vertigo is the result of labyrinthine edema as proposed by Wittmack, the end result of allergic manifestation.
