Introduction:
Treatment of hidradenitis suppurativa (HS) is challenging, and in Hurley stage I, it is based on topical measures. Our aim was to compare the efficacy and safety of topical resorcinol 10% with topical clindamycin 1% and no therapy, in Hurley stage I HS.
Methods:
In this open, prospective, randomized trial, we studied 60 Hurley stage I patients with IHS4 ≤10. Group A was treated with topical resorcinol 10%; group B with clindamycin lotion 1%; and group C received no treatment. Patients were evaluated by total lesion count, the International Hidradenitis Suppurativa Severity Score System (IHS4) and the Dermatology Life Quality Index (DLQI) at baseline, 12 and 24 weeks. Self-reported number of flares and adverse events (AEs) were recorded.
Results:
A significant reduction in the mean total lesion count and DLQI scores were observed in group A, compared to group B at week 12 (p = 0.036, p < 0.001, respectively), and in the mean total lesion count, IHS4, and DLQI scores at week 24 (p = 0.034, p = 0.017, p < 0.001, respectively). Resorcinol 10% was well-tolerated with only mild AEs.
Conclusion:
Resorcinol 10% may represent a useful alternative for the long-term treatment of mild HS, which is superior to topical clindamycin and has a favorable safety profile.
