Quality of Life in Cohabitants of Patients with Hidradenitis Suppurativa: A Cross-sectional Study.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease that impairs patients' physical and mental health. However, few studies have considered the consequences of HS on cohabitants. The aims of this study were to explore the impact of HS on the quality of life (QOL) of cohabitants and to assess potentially associated factors. A cross-sectional study was conducted and patients with HS and their cohabitants were invited to participate. Validated questionnaires were used to measure QOL, anxiety and depression, type D personality and sexual dysfunction. The clinical variables of patients and the demographic characteristics of cohabitants were also collected. Twenty-seven patients and 27 cohabitants were included for analysis. Patients and cohabitants presented significant QOL impairment. A direct association was found between the Dermatology Life Quality Index (DLQI) and the Familiar Dermatology Life Quality Index (FDLQI). DLQI scores were associated with the presence of negative affectivity, a trait typical of type D personality, as well as with cohabitants' anxiety. FDLQI scores were associated with cohabitant anxiety and patient depression. Hidradenitis suppurativa damages quality of life in patients and cohabitants. Identifying potential psychological factors could help us to recognize at-risk patients and apply personalized treatments for them and their environment
