The treatment was found to be non-inferior to surgery in relation to initial response rates, but with significantly better cosmetic outcomes.
Researchers reviewed 35 patients taking glucocorticoids for chronic skin diseases. The study found that only 20% were taking bisphosphonates, a medication proven to prevent glucocorticoid-induced osteoporosis. The authors recommend prescribing bisphosphonates concomitantly with corticosteroid therapy in certain cases.
