Antiandrogen therapies have demonstrated some reduction in HS flares. Although recommendations for use in HS is based on limited evidence, one randomized controlled trial compared ethinyl estradiol–norgestrel to ethinyl estradiol and cyproterone acetate. Both therapies resulted in similar efficacy, with 12 of 24 (50%) patients reporting HS symptoms improving or completely resolved.31 In another retrospective study of women treated with antiandrogen therapies, including ethinyl estriol, cyproterone acetate, and spironolactone, 16 of 29 (55%) patients reported improvement.32 In another study, daily doses of 100 to 150 mg of spironolactone resulted in improvement in 17 of 20 (85%) patients, including complete remission in 11 of 20 (55%) patients. Of the 3 patients with severe HS, none had complete clearing of disease burden.33 Patients with polycystic ovary syndrome or HS flares that occur around menstruation are more likely to benefit from treatment with spironolactone.18,32,34
Retinoids frequently have been utilized in the management of HS. In some retrospective studies and other prospective studies with 5 or more patients, isotretinoin monotherapy was utilized for a 4- to 10-month period.18,35-38 In the Alikhan et al18 study, 85 of 207 patients demonstrated improvement of HS symptoms, with more remarkable improvements in milder cases. Isotretinoin for management of patients with HS who have concomitant nodulocystic acne would have two-fold benefits.18
Wound Care
Given the purulent nodular formation in HS, adequate wound care management is vital. There is an abundance of HS wound care management strategies utilized by clinicians and patients. When selecting the appropriate dressing, consideration for the type of HS wound, cost, ease of application, patient comfort, absorbency, and odor management is important.3 However, living arrangements for military SMs can create difficulties applying and maintaining HS dressings, especially if deployed or in a field setting. Active-duty SMs often find themselves in austere living conditions in the field, aboard ships, or in other scenarios where they may or may not have running water or showers. Maintaining adequate hygiene may be difficult, and additional education about how to keep wounds clean must be imparted. Ideal dressings for HS should be highly absorbent, comfortable when applied to the anatomic locations of the HS lesions, and easily self-applied. Ideally, dressings would have atraumatic adhesion and antimicrobial properties.3 Cost-effective dressing options that have good absorption capability include sanitary napkins, adult briefs, infant diapers, and gauze.3 These dressings help to wick moisture, thus protecting the wound from maceration, which is a common patient concern. Although gauze dressings are easier to obtain, they are not as absorbent. Abdominal pads can be utilized, but they are moderately absorbent, bulky, and more challenging to obtain over-the-counter. Hydrofiber and calcium alginate dressings with silver are not accessible to the common consumer and are more expensive than the aforementioned dressings, but they do have some antimicrobial activity. Silver-impregnated foam dressings are moldable to intertriginous areas, easy to self-apply, and have moderate-heavy absorption abilities.
Final Thoughts
Hidradenitis suppurativa poses cumbersome and uncomfortable symptoms for all patients and may pose additional hardships for military SMs or those with physically demanding occupations who work in austere environments. Severe HS can restrict a military SM from certain duty stations, positions, or deployments. Early identification of HS can help reduce HS flares, disfigurement, and placement on limited duty status, therefore rendering the SM more able to engage in his/her operational responsibilities. Hidradenitis suppurativa should be discussed with the patient, with the goal to prevent flares for SMs that will be in the field, placed in austere environments, or be deployed. Use of immunosuppressants in active-duty SMs may affect their deployability, duty assignment, and retention.
For a military SM with HS, all aspects of prevention and treatment need to be balanced with his/her ability to remain deployable and complete his/her daily duties. Military SMs are not guaranteed the ideal scenario for treatment and prevention of HS. Unsanitary environments and occlusive uniforms undoubtedly contribute to disease process and make treatment more challenging. If a military SM is in a field setting or deployed, frequent daily dressing changes should still be attempted.
