广东省15例马尔尼菲青霉病临床分析

目的 分析广东省马尔尼菲青霉病的发病情况、临床特征、诊断要点、治疗及预后。方法 对1988-2003年发生于广东的15例马尔尼菲青霉病患者的一般资料、临床表现、体征、实验室检查特点及治疗反应和预后进行分析。结果 15例患者中男10例,女5例;发病者没有一定的职业区别,但并发艾滋病患者多为司机和无业人员。13例伴发有各种免疫缺陷的基础病,如艾滋病、结缔组织病、肾移植等。临床症状多种多样,主要为发热、消瘦、皮疹、呼吸系统症状等。皮损组织切片可见成堆的PAS染色阳性的圆形或腊肠形孢子。15例患者中4例为皮肤限局性感染,11例为系统性感染;9例死亡,5例治愈,1例放弃治疗。分离于不同部位的15株病原菌经形态学、培养的双相性皆证实为马尔尼菲青霉,其中11株经DNA测序也得到进一步证实。结论 广东近年马尔尼菲青霉病患者增多,且伴发艾滋病者增多,应引起重视。

Penicillium marneffei Infection in Guangdong Province China:Clinical Analysis of 15 Cases

Objective To analyze the incidence of the disease, clinical features, diagnostic criteria, therapy and prognosis of Penicilliosis marneffei found in Guangdong province. Methods To analyze patients data, clinical features, laboratory findings, response to therapy, and prognosis of 15 cases Penicilliosis marneffei found in Guangdong province of China. Results The male was predominant compared with the female (ratio 2 to 1) and without occupational preference, but the patients with AIDS as underlying disease were mostly drivers and the unemployed. Thirteen patients were immunocompromised such as AIDS, connective tissue disease, and kidney transplant. Clinical features showed different manifestations, such as high fever, loss of weight, skin lesion, and respiratory system symptoms. Biopsy of the skin lesion showed PAS stain positive yeast-like, or sausage-form spores. Four patients were localized infection of the skin, eleven patients were systemic infection. Nine patients died, five recovered, 1 patient refused to be treated. Fifteen isolates from different anatomic sites of the patients were identified to be Penicillium marneffei by morphology and dimorphism in the culture, and eleven isolates among these 15 isolates were also confirmed by DNA sequence analysis. Conclusion The incidence rate of Penicilliosis marneffei become higher in the recent years and many patients were accompanied with AIDS in Guangdong province. Attention should be paid to the disease.
