“…Tetracyclines or in severe non-responding cases clindamycin and rifampicin (also effective against intracellular Staphylococcus aureus), often combined with local administration of glucocorticoids, are able to halt the disease in many patients, but not all, by their effects against Staphylococcus aureus and probably also by their anti-inflammatory effects [8,9]. Other therapeutic options include oral corticosteroids, topical antiseptic substances, tacrolimus, isotretinoin, dapsone, and, recently, tumor necrosis factor (TNF) blocking agents (adalimumab and infliximab) [3,6,7]. However, there are still patients in whom these therapeutic options are either not all applicable or not sufficiently efficacious, so that the disease remains active and causes considerable discomfort with pruritus or trichodynia.…”
