Prevalence and clinical characteristics of itch in epidemic-like scenario of dermatophytoses in India: a cross-sectional study.

BACKGROUND

Itch is an integral part of clinical picture of superficial dermatophytoses which constitute a common and growing problem in India.

OBJECTIVES

The study aimed to evaluate the prevalence, intensity and clinical characteristics of itch in superficial dermatophytosis.

METHODS

The data concerning disease history and clinical type of dermatophytosis were obtained. The presence and various characteristics of itch were documented. Numerical Rating Scale (NRS) was utilized to assess the worst intensity of itch during the last 3 days and during the course of the disease. 4-Item Itch Questionnaire was utilized to assess itch extent, intensity, frequency and associated sleep impairment, while quality of life (QoL) impairment was assessed via Dermatology Life Quality Index.

RESULTS

Ninety-nine patients with direct microscopic confirmation of dermatophytosis were included in the study. In 46.5% of subjects, the coexistence of tinea corporis and tinea cruris was noted, followed by tinea cruris (25.2%) and tinea corporis (13.1%). The majority of patients reported itch in the last 3 days (99%) and complained of itch limited to skin lesions (89.9%). According to NRS, the mean intensity of worst itch in the last 3 days was 6.8 ± 1.8 points. Severe and very severe itch was reported by 74.7% of patients. Itch was an isolated sensation in 34.3% of subjects, while 46.9% reported associated burning sensation. Itch was frequently exacerbated by sweating, hot temperature and wearing tight clothes. Difficulties in falling asleep and sleep awakenings were reported by 34.3% and 54.6% of subjects, respectively. Itch negatively influenced the well-being of patients and its intensity correlated with QoL impairment.

CONCLUSIONS

Itch is an important symptom in superficial dermatophytoses and is associated with negative impact on sleep and carries a significant psychosocial burden. Acknowledging its presence is necessary in a holistic approach to these patients.
