目的探讨江门地区老年甲真菌病的致病真菌分布与临床类型的特点。方法对107例具有甲真菌病学典型临床表现并经病甲屑镜检阳性的老年患者进行真菌培养,对靶病甲进行临床形态学分型,填写调查问卷调查易感因素。结果121例靶病甲培养的病原菌分别为皮肤癣菌71.07%、酵母菌25.62%、霉菌3.31%;临床类型为全甲毁损型48.76%、远端侧位甲下型24.79%、近端甲下型19.01%、白色浅表型7.44%;107例问卷调查示糖尿病患者15例(14.02%)。结论江门地区老年甲真菌病致病菌主要为皮肤癣菌,临床类型以全甲毁损型为主,红色毛癣菌为其优势菌;糖尿病为其主要易感因素。
Objective To investigate the distribution of pathogenic fungi and the clinical characteristics of onychomycosis in Jiangmen area. Methods A total of 107 cases with typical clinical manifestations of onychomycosis were enrolled in this study. Fungal culture was performed in elder patients with candidal candidiasis. Clinical morphological typing was performed on the target disease and questionnaires were used to investigate susceptibility factors. Results The 121 pathogens of target pathogen A were dermatophytes 71.07%, yeast 25.62%, and molds 3.31% respectively. The clinical type was 48.76% of the total thymoid lesion and 24.79% of the distal inferior hypothyroidism, 19.01% of cases and 7.44% of white superficial cases. Among 107 cases, 15 cases (14.02%) were diabetic patients. Conclusion The main pathogens of onychomycosis in Jiangmen area are dermatophytes. The clinical types are mainly full-size ones and Trichophyton rubrum is the predominant bacteria. Diabetes mellitus is the major predisposing factor.
