Antibiotics are recognized as first-line treatments for hidradenitis suppurativa (HS), but the data on their efficacy are limited.
Evaluate the efficacy of oral clindamycin versus that of clindamycin plus rifampicin in patients with HS.
A total of 60 patients with mild-to-moderate-severe HS who were classified according to their International Hidradenitis Suppurativa Severity Score System (IHS4) and Hurley scores, were subdivided into 2 groups of 30 patients each (group A, the members of which received clindamycin plus rifampicin, and group B, the members of which were treated with clindamycin alone) and retrospectively studied. The main objective was to evaluate and compare the clinical and ultrasound responses between the groups after 8 weeks of treatment according to the Hidradenitis Suppurativa Clinical Response measure.
After the treatment, 17 of 30 patients in group A and 19 of 30 in group B met the primary outcome. Both groups showed a similar improvement of IHS4 score, whereas the Dermatology Life Quality Index and pain Visual Analogue Scale scores improved more in group B. In particular, the reductions in nodule and abscess counts were similar between the 2 groups, whereas the number of draining tunnels decreased more in group B. The factors significantly associated with Hidradenitis Suppurativa Clinical Response score were age, body mass index, IHS4 score, and absence of axillary involvement. Disease-free survival was similar between the 2 groups.
The study was not randomized or placebo-controlled.
Clindamycin may be a useful treatment alternative to antibiotic combination regardless of HS clinical stage.Le texte complet de cet article est disponible en PDF.
