Abstract

嗅覚障害の治療としてステロイド薬の点鼻療法が一般的に行われているが, 治療が長期にわたる症例も多くその副作用が懸念される. ステロイド薬点鼻療法長期連用に関してその安全性を有用性と比較して検討した報告はない. そこで今回は当科嗅覚味覚外来で同療法を施行した患者を対象にこの比較検討を施行した.<BR>0.1%リン酸ベタメタゾンナトリウム液 (リンデロン液®) の点鼻療法を施行した62例中42例 (68%) に点鼻開始後1~2カ月で血清ACTHまたはコルチゾール値の低下が出現したが, 異常な理学的所見や自覚的症状は認められなかった. 点鼻療法を中止した8例は全例1カ月後にそれらの値が正常範囲内に回復した. 一方, 同療法を継続した34例中4例で開始後2~5カ月で自覚的な顔面腫脹感, 顔面の濃毛化というステロイド薬のminor side effectが出現したが, 中止後1カ月ですべての症状が消失した. 同療法のみを3カ月以上継続した23例の治療効果は, 自覚的嗅覚障害度, 基準嗅力検査上ともに統計学的に有意な改善がみられ, 日本鼻科学会嗅覚検査検討委員会制定の嗅覚改善評価法でも78%例で何らかの改善判定が得られた.<BR>ステロイド薬点鼻療法の長期連用は軽度で可逆的な副作用を生じ得る. 一方, 嗅覚障害の治療効果は高い. よって同療法は有用な嗅覚障害の治療法であり, 臨床的必要性に応じて十分な注意の下に長期連用することは可能と考えられる.

Intranasal topical steroids are commonly used for the treatment of olfactory dysfunction. Although the side effects are considered to be minimal, these have not been studied in detail. We examined the side effects of intranasal topical treatment with steroids in patients with olfactory dysfunction. We treated 62 patients with intranasal topical application of 0.1% betamethasone sodium phosphate (Rinderone<SUP>_??_</SUP>) administered to the olfactory clefts. After treatment for 1 or 2 months. serum ACTH or cortisol was reduced in 42 (68% of total) patients, however, no clinical symptoms associated with steroid side effects were observed. The treatment was discontinued in 8 of these patients, who elected to withdraw from the treatment. In these patients, the serum ACTH or cortisol returned to normal a month after stopping the treatment. In the remaining 34 patients, the topical treatment was continued and in only 4 of these patients, minor steroid-as-sociated side effects such as the sensation of facial swelling and facial hair thickening, appeared 2-5 months after beginning the treatment. These side effects disappeared within a month after stopping the treatment. Regarding the therapeutic efficacy, in 18 (78%) of the 23 patients who continued treatment for an average period of 5 months, steroid treatment significantly improved their olfactory dysfunction. In conclusion, although it is important to consider the potential side effects of long-term intranasal topical treatment with steroids for olfactory dysfunction, this treatment is a highly effective method against olfactory dysfunction with minimal side effects.
