The treatment of psoriasis with etretinate and acitretin: a follow up of actual use.

The present study is a retrospective search on the actual use of systemic retinoids in the treatment of psoriasis. The design of the study was inclusion of the patients in whom retinoid treatment was initiated from 1981 up to 1989. The analysis was carried out in 1999, after at least 10 years of follow up. In total 94 patients were included, who were treated with etretinate or acitretin, out of a cohort of 2,000 patients with psoriasis at the Nijmegen Department of Dermatology. The majority of the patients were older than 40 years, 31% were suffering from pustular psoriasis, 6% from erythrodermic psoriasis and 17% from psoriasis arthropatica. Most patients had had psoriasis for more than 5 years and in 56% of them retinoids were the first systemic treatment. Continuous treatment for more than one year was recorded in 33% of the patients. During long-term follow up of at least 10 years, 25% of them were included again for acitretin treatment. Therefore, prolonged treatment actually had occurred in approximately half of the patients. In contrast to the common belief, erythrodermic psoriasis proved to be not the typically "low-dose" - and pustular psoriasis was not the typically "high dose" indication. The present study, however, reconfirmed the high efficacy of systemic retinoids in pustular- and erythrodermic psoriasis. It was also reconfirmed that systemic retinoids are not effective in arthropathic psoriasis. The occurrence of side effects largely followed the controlled investigations. At least 10 years' follow up had not revealed serious side effects. In those patients (n = 30) who completed the entire survey in the Nijmegen centre 19 patients were treated with at least one course of photo(chemo)therapy and 9 patients were treated subsequently with methotrexate.
