Clinical Characteristics of Pruritus and Pain in Patients with Hidradenitis Suppurativa.

A growing body of research has indicated that pruritus is an important feature of hidradenitis suppurativa (HS). This study evaluated pruritus and pain among 103 patients with HS. Pruritus and pain intensity were assessed with a visual analogue scale, numerical rating scale and 4-item Itch Questionnaire. Dermatology Life Quality Index (DLQI) was implemented to assess quality of life (QoL) issues. Various clinical features and factors influencing pruritus were also examined. Pruritus and pain during the last week were reported among 41.7% and 77.5% of patients, respectively. The presence of pruritus did not have an impact on DLQI, nor did it show interaction with the pain in this regard. The presence of pain was a crucial contributor, even more relevant than disease severity. None-theless, intensity of pruritus correlated positively with DLQI. The most troublesome symptom of HS was pain, followed by exudation, pruritus, appearance and smell, consecutively. Pruritus of mild-to-moderate intensity is a common HS-associated symptom that adversely affects patients' QoL.
