吸入ステロイドの副作用の一つとして,口腔・食道カンジダ症の報告がある.点鼻ステロイド長期投与により出現した「嚥下による口腔・食道通過時に不快感」の症状を呈した症例に口腔・食道カンジダ症を発見した.そして点鼻ステロイドを中止したことにより著明に改善した症例を経験したので報告する.症例は69歳女性.嚥下時上胸部に通過障害の違和感を主訴にて来院した.数年前より通年性アレルギー性鼻炎と診断され, 2年前より点鼻用BDPを毎日睡眠前に点鼻していたことを内視鏡検査後の問診でわかった.患者は睡眠中の鼻閉鼻汁の強い症状が, BDP点鼻により改善することで,使用し続けていた.経過:上部消化管内視鏡検査により下咽頭炎及び食道カンジダ症「吸入ステロイドによる食道カンジダ症の分類」のhigh grade(Grade III)を認めた.治療対策として,点鼻BDPを中止し抗真菌剤は使用せずに,毎日うがい・鼻洗を実施, 2週間後に主訴が改善, 1ヵ月半後の内視鏡再検査にてmild grade(Grade I)に改善していた.睡眠前の吸入ステロイド使用と同様に,睡眠前の点鼻も経鼻腔的に食道にステロイドが嚥下され滞留し, 1年以上長期に点鼻ステロイドを使用した結果,食道カンジダ症が発症したと思われた.
In general, steroid is mainly used as anti-inflammatory action in case of allergic diseases. As one of the side effects of inhalation steroid, a report is given below regarding buccal capsule/esophageal candidiasis. The patient came to the hospital with the chief complaint regarding passage dysphagia in the time of deglutition; pharyngitis and esophageal candidiasis were found by endoscopy of upper gastrointestinal tract.The interview after the endoscopy revealed that the patient, a 69-year-old female was diagnosed as chronic perennial allergic rhinitis a few years ago, and had been inhaling rhinenchysis Beclometasone dipropionate (BDP) before sleep every day for the past two years because using this collunarium seemed to mitigate the nasal obstruction and mucus during sleep. The patient did not report this fact before the endocsopy because she did not associate it with her subjective symptom. In this case, it was assumed that nebulized rhinenchysis BDP was accidentally swallowed to the pharynx and esophagus during sleep. As a treatment, rhinenchysis BDP was canceled and instead Azunol mouth washing (gargling/nasal douche) was used. No antifungal agent was used. In two weeks, the patient reported some improvement, and this was confirmed by reexamination of the upper gastrointestinal tract using endoscope in one month and a half. Pharyngitis was improved, and in the didital endoscopic assessment of esophageal candidiasis complincating inhaled steroid therapy the esophageal candidiasis became Grade I (mild grade). As for the later progress, the patient did not report any subjective symptoms such as nasal obstruction and dysphagia. In addition, the inflammation caused by candidiasis and found in the early examination was improved. The patient in this case was under treatment for thrombosis in the vein of lower extremity, but no complications such as diabetes mellitus or immune deficiency syndrome were observed. Discussion: Esophageal candidiasis by chronic administration of inhalation of steroid before sleep for asthmatic patients has been reported. However, there has not been a report of esophageal candidiasis by chronic administration of rhinenchysis steroid before sleep for patients with allergic rhinitis. Similarly, in the case of the use of steroid in the form of collunarium before sleep, steroid stayed in the esophagus via the transendothelial nasal cavity, and that seemed to cause, in the long run, to develop esophageal candidiasis. Conclusions: One of the implications of the above case is that collunarium can go down, even when it is nebulized in the nasal cavity, to the esophagus via the nasal cavity to buccal capsule. This suggests the necessity for preventative measures in the case of chronic administration of steroid as follows. A. Blowing of the nose just after the use of collunarium B. Daily rinsing (gargling and nasal douche)
