Tinea pedis typically presents as a pruritic, erythematous, and scaly eruption on the foot, with symptoms correlated with the severity of infection. Although many clinical studies have assessed the antifungal action of various agents, relatively little attention has been devoted to evaluating if antifungal agents are capable of improving subjective symptoms while treating the infection. A single-center, open-label, observational, proof of concept study was conducted in 21 participants (age range, 16-74 years) to evaluate if sertaconazole nitrate cream 2% used twice daily for 7 days was able to reduce participants' perceived itching while treating the infection. Findings included participants' overall assessment of quality of life (QOL) with the Dermatology Life Quality Index (DLQI) and participants' overall satisfaction with treatment. The pruritus visual analog scale (VAS) was used to assess the subjective symptom of itching. Results indicated the mean total score of changes in perception of QOL was 8.95 at baseline and 3.38 at day 7, a within-group change of -5.57 (P < .0001), and the mean reduction in reported itching from baseline to day 7 was -63.10% (P < .0001). Fifteen of 21 participants (71.4%) were somewhat or very satisfied with the results of their treatment. The implication of these findings is that successful elimination of the inflammatory symptoms of tinea. pedis, such as pruritus, may promote adherence to therapy by directly affecting participants' perception of QOL. Furthermore, early and rapid relief of symptoms, as seen in this study, may encourage patients to continue therapy for the full recommended period of 4 to 6 weeks, thereby reducing the risk for relapse that leads to chronic disease.
足癣通常表现为足部瘙痒、红斑和鳞屑性皮疹,症状与感染严重程度相关。尽管许多临床研究评估了各种药物的抗真菌作用,但相对较少关注评估抗真菌药物在治疗感染时是否能够改善主观症状。一项单中心、开放标签、观察性概念验证研究纳入了21名参与者(年龄范围16 - 74岁),以评估每天两次使用2%的硝酸舍他康唑乳膏,持续7天是否能够在治疗感染的同时减轻参与者的瘙痒感。研究结果包括参与者使用皮肤病生活质量指数(DLQI)对生活质量(QOL)的总体评估以及参与者对治疗的总体满意度。瘙痒视觉模拟量表(VAS)用于评估瘙痒的主观症状。结果显示,QOL感知变化的平均总分在基线时为8.95,第7天时为3.38,组内变化为 -5.57(P < .0001),从基线到第7天报告的瘙痒平均减轻了 -63.10%(P < .0001)。21名参与者中有15名(71.4%)对治疗结果有些或非常满意。这些研究结果表明,成功消除足癣的炎症症状,如瘙痒,可能通过直接影响参与者的生活质量感知来促进治疗依从性。此外,如本研究所示,症状的早期快速缓解可能会鼓励患者在整个推荐的4至6周疗程内持续治疗,从而降低导致慢性病的复发风险。
