The causative fungi of tinea capitis vary with geography and time. This study was planned to identify the etiologic agents and determine clinicoetiologic correlations of tinea capitis in Lahore, Pakistan.
From clinically suspected cases of tinea capitis, skin scrapings and hair samples were taken and subjected to microscopy and culture.
Of 180 evaluable patients, 95% were children below 12 years of age with equal sex incidence. Noninflammatory lesions were seen in 62.2% of cases. Trichophyton violaceum was the most common etiologic agent responsible for 69.4% of infection, followed by T. tonsurans (16.7%), T. verrucosum (10%), Microsporum audouinii (2.2%), and T. mentagrophytes (1.7%).
T. violaceum is the predominant pathogen causing tinea capitis in children and adults in this part of the world and gives rise to a varied clinical picture. Our findings agree with data from other parts of Pakistan and many countries abroad.
头癣的致病真菌因地域和时间而异。本研究旨在确定巴基斯坦拉合尔头癣的病原体,并确定临床病因学相关性。
从临床疑似头癣病例中采集皮肤刮屑和毛发样本,进行显微镜检查和培养。
在180例可评估患者中,95%为12岁以下儿童,男女发病率相等。62.2%的病例出现非炎症性病变。紫色毛癣菌是最常见的病原体,占感染病例的69.4%,其次是断发毛癣菌(16.7%)、疣状毛癣菌(10%)、奥杜盎小孢子菌(2.2%)和须癣毛癣菌(1.7%)。
在世界这一地区,紫色毛癣菌是导致儿童和成人头癣的主要病原体,并呈现出多样的临床症状。我们的研究结果与巴基斯坦其他地区和许多国外国家的数据一致。
