The aim of the present study was to investigate Demodex species infestation in patients with ear itching. The relationship between the severity of ear itching and Demodex spp. positivity has not been previously reported in the literature, and we believe that our study will make a significant contribution to the understanding of the etiology of ear itching.
Fifty patients with itching ears and 54 healthy control patients were asked to use a visual analogue scale (VAS) to rate the itch, the itching period, and the medication used for the itching. All samples were evaluated for Demodex spp. under a light microscope.
There was no statistically significant difference between the groups in terms of numbers of Demodex spp. (p=0.154), and there was no statistically significant difference between the groups in terms of Demodex spp. positivity (p=0.054). Despite the lack of statistically significant differences, Demodex spp. infestations were more common in the affected group than in the control group. A positive and strongly significant relationship was observed between the number of Demodex spp. and severity of ear itch in the patient group based on VAS scores (p=0.0001; r=0.724).
We found that an increased number of Demodex spp. was strongly related to increased severity of ear itching.
本研究旨在调查耳部瘙痒患者的蠕形螨感染情况。耳部瘙痒严重程度与蠕形螨属阳性之间的关系此前尚未见文献报道，我们相信我们的研究将为理解耳部瘙痒的病因做出重大贡献。
50例耳部瘙痒患者和54例健康对照者被要求使用视觉模拟量表（VAS）对瘙痒程度、瘙痒持续时间以及用于止痒的药物进行评分。所有样本均在光学显微镜下评估蠕形螨属情况。
两组在蠕形螨属数量方面无统计学显著差异（p = 0.154），在蠕形螨属阳性方面两组也无统计学显著差异（p = 0.054）。尽管缺乏统计学显著差异，但蠕形螨属感染在患病组比对照组更常见。基于VAS评分，在患者组中观察到蠕形螨属数量与耳部瘙痒严重程度之间存在正相关且具有高度显著性（p = 0.0001；r = 0.724）。
我们发现蠕形螨属数量增加与耳部瘙痒严重程度增加密切相关。
