Central centrifugal cicatricial alopecia (CCCA) is a type of scarring hair loss primarily seen in African-American women. The risk factors that affect the severity of disease remain unclear.
This study was designed to elucidate risk factors that may be associated with severity of CCCA.
A cross-sectional survey study was conducted. Women with biopsy-confirmed CCCA responded to a questionnaire and were grouped according to a photographic scale of central scalp alopecia. The severity of disease was considered: grade 1 and 2 disease was interpreted as early-stage CCCA, and grade 3-5 disease was interpreted as advanced-stage CCCA. Data from the questionnaire were compared with levels of severity to determine the strength of associations with severity of disease.
A total of 38 women with biopsy-confirmed CCCA were recruited to participate in this study. Early-stage CCCA was seen in 22 subjects (57.9%), and advanced-stage CCCA was noted in 16 subjects (42.1%). The average duration of hair loss was 5.7 years in early-stage disease and 10.1 years in advanced-stage disease. There was a positive correlation between duration of hair loss and degree of hair loss (Spearman's correlation 0.471, P = 0.003).
This study reports on data sourced from patients with biopsy-confirmed CCCA and examines the relationships between various factors and severity of CCCA. The findings demonstrate that duration of hair loss is positively associated with severity of disease and that androgen-related conditions are prevalent in those affected with CCCA.
中心离心性瘢痕性秃发(CCCA)是一种主要见于非裔美国女性的瘢痕性脱发。影响疾病严重程度的危险因素尚不清楚。
本研究旨在阐明可能与CCCA严重程度相关的危险因素。
进行了一项横断面调查研究。经活检确诊为CCCA的女性回答了一份问卷,并根据头皮中央脱发的照片分级进行分组。疾病严重程度分为:1级和2级疾病被解释为早期CCCA,3 - 5级疾病被解释为晚期CCCA。将问卷数据与严重程度水平进行比较,以确定与疾病严重程度的关联强度。
共招募了38名经活检确诊为CCCA的女性参与本研究。22名受试者(57.9%)为早期CCCA,16名受试者(42.1%)为晚期CCCA。早期疾病的平均脱发持续时间为5.7年,晚期疾病为10.1年。脱发持续时间与脱发程度呈正相关(Spearman相关系数为0.471,P = 0.003)。
本研究报告了来自经活检确诊为CCCA患者的数据,并研究了各种因素与CCCA严重程度之间的关系。研究结果表明,脱发持续时间与疾病严重程度呈正相关,且雄激素相关疾病在CCCA患者中普遍存在。
