A Prospective Observational Study to Evaluate the Factors Affecting the Dermatology Life Quality Index in Patients With Hidradenitis Suppurativa

Background: Hidradenitis suppurativa (HS) is a chronic, relapsing inflammatory skin disease that significantly affects the quality of life of patients. Multiple factors affect the disease's course and severity. HS is a debilitating disease and often recalcitrant to treatment, resulting in a deterioration of quality of life; hence, there is a need to evaluate the factors affecting the quality of life in patients with HS. Objectives: The objective of the study was to evaluate the various demographic and disease-related factors that affect the quality of life of patients with HS. Materials and methods: This is a prospectively scored questionnaire-based observational study. Data from 30 patients with HS were analyzed for the association of disease-related factors like Hurley’s staging, site, duration, past history, and comorbidities with the Dermatology Life Quality Index (DLQI). Results: A statistically significant relationship was found between DLQI and Hurley staging (p=0.000). The most common sites involved were the axilla and inguinal regions. Among the sites involved, the neck (p=0.002), abdomen (p=0.002), back (p=0.002), thighs (p=0.042), and gluteal (p=0.000) regions have a statistically significant association with DLQI. Prior histories of rheumatoid arthritis, scarring, surgery, lymphadenitis, and pilonidal sinus showed a statistically significant association with DLQI. Conclusion: The disease severity significantly hampers the quality of life of patients with HS. The disease site and presence of other comorbidities also influence the outcome. Our study will help healthcare providers better understand and fulfill the needs of patients suffering from HS.
