摘要: 目的:探讨皮肤非结核分枝杆菌感染(nontuberculous mycobacteria,NTM)临床特点和诊疗方法,提高对皮肤NTM感染的认识和诊断水平。方法:收集2022年4月至2024年8月西京医院皮肤科门诊皮肤NTM感染疑诊患者57例,统计分析其培养法、抗酸染色和核酸测序检测结果,随访治疗和预后情况。结果:综合病史、临床和实验室检测结果最终诊断皮肤NTM感染34例,男18例(52.94%),女16例(47.06%),发病年龄14~81岁,平均(51.79±15.96)岁,以40岁以上年龄段为主,病期≥6个月患者占比最高72.22%。半数患者发病诱因与外伤有关,其中主要以鱼刺伤为主,多发皮损(22例,64.71%)高于单发皮损(12例,35.29%)。临床表现以斑块为主(15例,44.12%),主要位于手部(20例,58.82%)。核酸测序鉴定阳性率最高为85.29%,其次是抗酸染色70.59%,组织培养阳性率最低29.41%。菌种鉴定结果显示海分枝杆菌感染率最高21例(61.76%)。手术切除2例、中医治疗1例和抗生素治疗31例,28例临床治愈(82.35%),6例好转(17.65%),总有效率100%,复发4例(11.76%)。结论:皮肤NTM感染主要以海分枝杆菌感染为主,好发于中老年,皮损表现复杂多样,临床诊疗应综合考虑。

Abstract: Objective: To explore the clinical characteristics, diagnosis and treatment methods of cutaneous NTM (nontuberculous mycobacteria) infection, and to improve the understanding and diagnostic level of cutaneous NTM infection. Methods: From April 2022 to August 2024, 57 patients with suspected cutaneous NTM infection were collected from the Dermatology Outpatient Department of Xijing Hospital. The results of culture method, acid-fast staining, and nucleic acid sequencing, as well as the treatment and prognosis, were statistically analyzed. Results: Thirty four cases were finally diagnosed with cutaneous NTM infection, including 18 males (52.94%) and 16 females (47.06%). The onset age ranged from 14 to 81 years old, with an average age of (51.79±15.96) years old, mainly in the age group over 40 years old. Patients with disease duration ≥6 months accounted for the highest proportion(72.22%). Half of the patients had trauma-related onset causes, mainly fishbone stabbing. There were 22 cases (64.71%) of multiple skin lesions, which was higher than 12 cases (35.29%) of single skin lesions. The main clinical manifestation was plaques, accounting for 44.12%; the main affected site was the hand, accounting for 58.82%. The positivity rate of nucleic acid sequencing identification was the highest, which was 85.29%, followed by acid-fast staining of 70.59%, and that of tissue culture was the lowest, which was 29.41%. In terms of species identification results, the infection rate of Mycobacterium marinum was the highest, with 21 cases (61.76%). There was 2 case treated by surgical resection, 1 case with traditional Chinese medicine treatment and 31 cases treated with antibiotics. 28 cases (82.35%) were clinically cured, 6 cases (17.65%) improved, the total effective rate was 100%, and 4 cases (11.76%) relapsed. Conclusion: Cutaneous NTM infection is mainly caused by Mycobacterium marinum infection, which is more common in middle-aged and elderly people. The manifestations of skin lesions are complex and diverse, and comprehensive consideration should be given in clinical diagnosis and treatment.
