DISCUSSION

Dapsone is a sulfone drug that possesses anti-microbial and anti-inflammatory properties and is used in a broad range of indications. In the case of severe disease with previously failed treatment attempts, TNF-alpha inhibitors (adalimumab, infliximab) may be an appropriate treatment option. Since these biologics and dapsone address the main pathophysiology of HS with their TNF-alpha TNF-inhibiting properties, the use of these two agents in conjunction may have a synergistic benefit. Few studies observing the effects of oral dapsone on HS have been published.17,18 The most recent study was completed in 2011 and concluded that out of 24 patients, only 38% reported improvement. The patients who showed improvement had mild to moderate (Hurley Stage I-II) disease. A total of four patients in this study had severe (Hurley Stage III) HS and did not show any improvement. This study indicated that dapsone therapy is possible for patients with HS, particularly with milder cases.17 Another retrospective study followed five patients with HS who received dapsone therapy with improvement being reported in all five patients within 4-12 weeks.18 Overall, these previous studies support our results. However, our study differs from previous studies, with 89.5% of patients having severe (Hurley Stage III) disease.

In this retrospective review, 13/19 (68%) patients treated with dapsone showed improvement, while 6/19 (32%) did not have any change in symptoms (Table 3). Of the 13 patients who responded to treatment, 11 patients had advanced disease (Hurley Stage III; Table 1), suggesting the potential dapsone has as adjunctive therapy for moderate to severe disease (Hurley Stage II-III). The majority of the patients who showed improvement were also on combination therapy, either with immunomodulatory or antibiotic compounds. Of the two patients who were treated with monotherapy, one resulted in clinically significant improvement, and the other had no change. 

This study has several limitations. The effectiveness of dapsone used as monotherapy cannot be determined as the majority of the patients were taking dapsone in combination with other agents. In addition, a quality-of-life survey to assess the overall satisfaction of patients before and after treatment was not performed. The possibility of disease recurrence while patients were either on dapsone or at the cessation of dapsone treatment also was not assessed. Finally, observations were based on a small patient population with no control group.

CONCLUSIONS

Dapsone may be an effective treatment option when used in combination with other therapies for moderate to severe (Hurley Stage II-III) HS. Further studies are required to clarify the effect of dapsone used as a monotherapy, to evaluate which treatment options work best in combination with dapsone, and to assess the possibility of disease recurrence in patients with moderate to severe disease who initially respond to dapsone therapy.
