S3 - Guidelines on the treatment of psoriasis vulgaris (English version). Update.

Psoriasis vulgaris is a common and often chronic inflammatory skin disease. The incidence of psoriasis in Western industrialized countries ranges from 1.5% to 2%. Patients afflicted with severe psoriasis vulgaris may experience a significant reduction in quality of life. Despite the large variety of treatment options available, surveys have shown that patients still do not received optimal treatments. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologi sche Gesellschaft (DDG) and the Berufsverband Deutscher Dermatologen (BVDD) have initiated a project to develop evidence-based guidelines for the management of psoriasis. They were first published in 2006 and updated in 2011. The Guidelines focus on induction therapy in cases of mild, moderate and severe plaque-type psoriasis in adults including systemic therapy, UV therapy and topical therapies. The therapeutic recommendations were developed based on the results of a systematic literature search and were finalized during a consensus meeting using structured consensus methods (nominal group process).

Evidence-based (S3) guideline for the treatment of psoriasis vulgaris - Update: "Therapeutic options" and "Efalizumab".

In February 2009, the European Medicines Agency's (EMEA) Committee for Medicinal Products for Human Use (CHMP) had recommended the suspension of efalizumab's (Raptiva) marketing authorization, because its benefits in the treatment of psoriasis were modest, while there was a risk of serious side effects in patients receiving the medicine, including the occurrence of progressive multifocal leukoencephalopathy (PML). The guideline group has changed the guideline accordingly.

Evidence-based (S3) guidelines for the treatment of psoriasis vulgaris.

Psoriasis vulgaris is a common and often chronic inflammatory skin disease. The incidence of psoriasis in Western industrialized countries ranges from 1 to 2%. Patients afflicted with severe psoriasis vulgaris may experience a significant reduction in quality of life. Despite the large variety of treatment options available, patient surveys have revealed lack of satisfaction with the efficacy of available treatments and a high rate of non-compliance. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologische Gesellschaft (DDG) and the Berufsverband Deutscher Dermatologen (BVDD) initiated a project to develop evidence-based guidelines for the management of psoriasis. These resulting Guidelines focus on induction therapy in cases of mild, moderate, and severe plaquetype psoriasis in adults. The Guidelines include evidence-based evaluation of the efficacy of all currently available therapeutic options in Germany. In addition, they offer detailed information on how best to administer the various treatments and give information on contraindications, adverse drug reactions, and drug interactions as well as estimates of practicability and cost. The Guidelines were developed following the recommendations of the Arbeitsgemeinschaft wissenschaftlicher medizinischer Fachgesellschaften (AWMF). The therapeutic recommendations were developed by an expert group and finalized during interdisciplinary consensus conferences.

Psoriasis is a chronic immune-mediated skin disease with highly variable patterns of presentation, both between patients and in individuals over time. Its course can be influenced by various triggers. Since there is no cure for psoriasis, patients with moderate-to-severe plaque-type psoriasis often require lifelong therapy to control their disease. Traditional approaches such as cyclosporine or methotrexate are problematic for long-term use because of organ toxicity, other side effects, drug interactions and a loss of efficacy over time. Efalizumab is a recombinant monoclonal IgG1-antibody, approved in Germany for the management of moderate-to-severe plaque-type psoriasis. Its efficacy and safety have been demonstrated in clinical trials with thousands of patients,especially with regard to long-term therapy. Therefore, a change of paradigm from the traditional therapy of inflammatory episodes to continuous control of psoriasis seems possible. This supplement deals with practical aspects of using efalizumab in the outpatient setting.
