title: Hidradenitis suppurativa: A practical review of possible medical treatments based on over 350 hidradenitis patients.
abstract: Hidradenitis suppurativa (HS), a pathological follicular disease, impacts patients' lives profoundly. HS most commonly involves cutaneous intertriginous areas, such as the axilla, inner thighs, groin and buttocks, and pendulous breasts, but can appear on any follicular skin. Protean, HS manifests with variations of abscesses, folliculitis, pyogenic granulomas, scars (oval honeycombed), comedones, tracts, fistulas, and keloids. The pathophysiology might involve both defects of the innate follicular immunity and overreaction to coagulase negative Staphylococcus. Treatment depends on the morphology, extent, severity, and duration. Topical clindamycin and dapsone are often adequate for treating mild HS. For Stage 1 and 2 HS, first line treatment combines rifampin with either oral clindamycin or minocycline. Other HS treatments include: fluoroquinolones with metronidazole and rifampin, oral dapsone, zinc, acitretin, hormone blockers (oral contraceptive pills, spironolactone, finasteride, and dutasteride), and oral prednisone. For severe HS, cyclosporine, adalimumab, or infliximab (used at double psoriatic doses) and intravenous carbapenems or cephalosporins are often required. Isotretinoin, etanercept, isoniazid, lymecycline, sulfasalazine, methotrexate, metformin, colchicine, clarithromycin, IVIG, and thalidomide are less favored treatments. The role of botulinum toxin is uncertain. The most important life style modification is weight loss. De-roofing fluctuant nodules and injection of intralesional corticosteroids ameliorates the disease and perhaps, if done at regular intervals, improves HS more permanently. Surgical excision and CO2 laser ablation are more definitive treatments. The 1064 nm laser for hair removal aids in the treatment of HS. This article centers on medical therapies and will only passingly mention surgical and laser treatments. This article summarizes my treatment experience with over 350 HS patients.
