Esophageal candidiasis is one of the local side effects of inhaled corticosteroid treatment, and it is difficult to prevent this condition. Our previous report indicated that the prevalence of esophageal candidiasis among patients treated with inhaled fluticasone propionate dry powder (FP-dp) reached up to 37% in Japanese patients. Although a reduction in the daily dose of inhaled FP-dp can eliminate this infection, it may lead to asthma not being well-controlled in these patients.
The aim of this study was to estimate whether switching to an equal daily dose of inhaled hydrofluoroalkane-134a beclomethasone dipropionate (HFA-BDP), the oropharyngeal deposition of which is very low, can eliminate the infection without deterioration of asthma.
A total of 10 stable asthmatic patients with esophageal candidiasis, induced by inhaled FP-dp treatment (400 or 800 microg/ day), were enrolled in this study. A second upper GI endoscopy was performed, more than 1 month but less than 3 months after switching to an equal dose of inhaled HFA-BDP with a tube spacer device, Duopacer. The patients' medications were not changed during the study.
Esophageal candidiasis was eliminated in 9 of the 10 patients. The degree of candidiasis reduced in another patient. The forced expiratory volume in 1 sec (FEV1.0) did not worsen during the study.
Switching from FP-dp to HFA-BDP with Duopacer is useful in preventing esophageal candidiasis.
食管念珠菌病是吸入性糖皮质激素治疗的局部副作用之一,且难以预防。我们之前的报告指出,在日本患者中,吸入丙酸氟替卡松干粉(FP-dp)治疗的患者中食管念珠菌病的患病率高达37%。尽管减少吸入FP-dp的每日剂量可消除这种感染,但这可能导致这些患者的哮喘控制不佳。
本研究的目的是评估改用每日剂量相等的吸入性丙酸倍氯米松氢氟烷-134a(HFA-BDP,其口咽部沉积率非常低)是否能消除感染且不使哮喘恶化。
本研究共纳入10例因吸入FP-dp治疗(400或800微克/天)诱发食管念珠菌病的稳定哮喘患者。在改用等量的带储雾罐装置Duopacer的吸入性HFA-BDP后1个多月但不到3个月时,进行了第二次上消化道内镜检查。研究期间患者的用药未改变。
10例患者中有9例食管念珠菌病得以消除。另一例患者的念珠菌病程度减轻。研究期间第1秒用力呼气量(FEV1.0)未恶化。
从FP-dp改用带Duopacer的HFA-BDP对预防食管念珠菌病有效。
