Abstract

Introduction: Hidradenitis suppurativa (HS) is a chronic, debilitating condition that is underrecognized and poorly managed in South Africa. Hence, this study aimed to determine the prevalence of HS in KwaZulu-Natal, South Africa.

Methods: This multicenter, explorative, cross-sectional, and descriptive study was conducted on 500 persons accompanied by patients in a tertiary and private hospital in Ethekwini, KZN, South Africa, from 6th February to 16th March 2023. After obtaining consent, they were screened by a physician for HS on a validated questionnaire comprising questions for the presence of recurrent painful deep-seated boils in the axillae, breasts, groins, or perineum. Screened positive and selected (10%) negative persons were re-examined by a dermatologist. Relevant data on demographics, smoking, and body mass index (BMI) were also collected.

Results: From 500 participants, 9 were confirmed as HS and the point prevalence was 1.8%. The HS group comprised 8 females and 1 male, with a median interquartile range age of 36 years (IQR 29-42) and BMI of 27.3 kg/m2 (IQR 26.8-29.9). Four HS patients were of African ethnic origin (44.4%), and 5 were of Asian ethnic origin (55.6%). The majority of HS cases were graded as Hurley stage I (7/9 cases) and 2 were Hurley stage III. The sensitivity from the HS questionnaire was 100% and the specificity was 80%. The positive predictive value was 0.4 while the negative predictive value was 1.0.

Conclusion: The prevalence of HS in KwaZulu-Natal South Africa is 1.8%, with those of African and Indian ethnicity being more predisposed.

南非夸祖鲁-纳塔尔省德班地区化脓性汗腺炎的流行情况。

简介：化脓性汗腺炎（HS）是一种慢性衰弱性疾病，在南非未得到充分认识和管理不善。因此，本研究旨在确定南非夸祖鲁-纳塔尔省HS的患病率。方法：这项多中心、探索性、横断面和描述性研究于2023年2月6日至3月16日在南非KZN的一家三级和私立医院对500名患者进行了研究。在获得同意后，由医生通过一份有效的问卷对他们进行HS筛查，问卷包括腋窝、乳房、腹股沟或会阴是否存在复发性疼痛的深层疖子。筛选阳性和选择（10%）阴性的人由皮肤科医生重新检查。还收集了人口统计学、吸烟和身体质量指数（BMI）的相关数据。结果：500名参与者中，HS确诊9例，点患病率为1.8%。HS组包括8名女性和1名男性，年龄中位数为36岁（IQR 29-42）， BMI为27.3 kg/m2 （IQR 26.8-29.9）。其中非洲裔4例（44.4%），亚裔5例（55.6%）。大多数HS病例为Hurley I期（7/9），2例为Hurley III期。HS问卷的敏感性为100%，特异性为80%。阳性预测值为0.4，阴性预测值为1.0。结论：南非夸祖鲁-纳塔尔省HS患病率为1.8%，非洲裔和印度裔人群易患HS。
