Association between Inflammatory Markers and Psychometric Scores in Patients with Hidradenitis Suppurativa.

: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder with a significant impact on the quality of life of affected patients. This study aimed to correlate serum inflammatory markers with specific tools assessing quality of life, emotional well-being, and loneliness, such as the Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS), and the UCLA Loneliness Scale. : A pilot observational study including 37 patients with HS was conducted. Inflammatory serum markers, including C-reactive protein (CRP) and Erythrocyte Sedimentation Rate (ESR), were evaluated at baseline, 3 months, and 6 months later. Psychometric scores were also evaluated at the same study intervals. : DLQI was correlated with ESR at baseline (Spearman's rho = 0.35, = 0.03), indicating that poorer quality of life is associated with changes in this serum marker. Disease activity, as reflected by inflammatory markers, was associated with significant psychological burden. Specifically, a worse DLQI score was associated with higher ESR (estimate β = 0.14, 95% confidence interval [CI]: 0.05-0.22; = 0.001) and higher CRP level (estimate β = 0.25, 95% CI: 0.02-0.48; = 0.02). Similarly, a worse UCLA score was associated with higher ESR (estimate β = 0.11, 95% CI: 0.02-0.20, = 0.01). : Our study results underline the close relation between systemic inflammatory markers and clinical severity together with psychological burden in HS patients, as indicated by the significant association that was revealed between ESR/CRP and poorer psychometric scores. However, further research is warranted to validate these findings.
