Adjuvant triamcinolone acetonide injections in oro-pharyngeal pemphigus vulgaris

Background High-potency topical and perilesional/intralesional corticosteroids are becoming increasingly useful as adjuvant to treat autoimmune blistering diseases. Objective We sought to evaluate the role of perilesional/intralesional triamcinolone acetonide (PITA) injections in reducing the time for first complete clinical remission and the total amount of systemic corticosteroids in oro-pharyngeal pemphigus vulgaris (OPV) patients, and also the compliance of PITA injections, in terms of satisfaction, pain and discomfort. Methods Thirty-five OPV patients were treated with conventional immunosuppressive therapy (CIST) and received high potency topical corticosteroids (clobetasol and/or methylprednisolone) and/or PITA injections. Patients were grouped as follows: (i) a group of 16 patients was treated with PITA injections and (ii) a group of 19 patients without PITA injections. Results Sixteen patients treated with PITA injections and 19 without PITA injections reached complete clinical remission within 126.6 days (SD: 41; 95% CI: 104.7-148.8) and 153.2 days (SD: 97.4; 95% CI: 106.2-200.1) (P = 0.4) respectively. The total amount of corticosteroids in patients treated with PITA and without PITA was 4894 mg (SD: 2832; 95% CI: 3385-6403) and 5312 mg (SD: 4009; 95% CI: 3380-7245) (P = 0.4) respectively. Patients treated with PITA reported a satisfaction score significantly higher than pain (P = 0.0007) and discomfort score (P = 0.0006). Conclusion Perilesional/intralesional triamcinolone acetonide injections seems to represent a helpful clinical tool to successfully join CIST, in terms of shortening the time of complete clinical remission, reducing the total amount of corticosteroids and obtaining an acceptable compliance. © 2010 European Academy of Dermatology and Venereology.
