title: Reduction in pain scores and improvement in depressive symptoms in patients with hidradenitis suppurativa treated with adalimumab in a phase 2, randomized, placebo-controlled trial.
abstract: BACKGROUND
  Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory skin disease with frequent comorbidities of painand depression. Adalimumab treatment for 16 weeks improved HS lesions significantly versus placebo (NCT00918255).
  
  
  OBJECTIVE
  The relationship between pain and depressive symptoms and the effects of adalimumab on each was examined in this post hoc analysis.
  
  
  METHODS
  Patients with moderate to severe HS (N=154) were randomized 1:1:1 to adalimumab 40 mg weekly (ew), adalimumab 40 mg every other week (eow), or placebo. Skin pain was assessed using a visual analog scale (VAS; 0-100 mm). Depressive symptoms were assessed using the 9-item Patient Health Questionnaire (PHQ-9; score ≥10 indicative of depression).
  
  
  RESULTS
  At baseline, overall mean±SD pain VAS was 54.3±26.5 mm and 41.8% of patients had PHQ-9 scores ≥10. At baseline, VAS pain scores (mean±SD) were significantly higher (P&lt;0.001) for patients with PHQ-9 scores ≥10 (63.9±23.3) versus &lt;10 (47.4±26.7). At Week 16, clinically relevant pain reduction was observed for ew-treated patients with baseline PHQ-9 score ≥10 (ew, 45.8%; eow, 29.4%; placebo, 23.8%) and &lt;10 (ew, 50.0%; eow, 37.9%; placebo, 29.6%), but did not reach statistical significance. In patients with high baseline pain (≥median VAS score), adalimumab ew significantly decreased depressivesymptoms versus placebo (PHQ-9 scores, -34.03% vs +2.26%; P&lt;0.01).
  
  
  CONCLUSIONS
  Patients with moderate to severe HS had a high degree of pain and depressive symptoms at baseline. Adalimumabtherapy was associated with decreased pain and depressive symptoms compared to baseline.
