    Abstract:
    The chronic skin disease psoriasis frequently requires long-term systemic treatment with agents that suppresses the immune system with little specificity, which can lead to systemic side effects. Today, using recombinant techniques, it is possible to produce modified proteins, the so-called biologicals, that target specific molecules in the inflammatory process. For the biologicals etanercept, infliximab, adalimumab, efalizumab and alefacept, the clinical efficacy expressed in the rates of partial remission (75% reduction in skin lesions) in patients with plaque psoriasis range from 12 to 88%, compared with 22 to 87% for existing systemic therapies for psoriasis. The side effects of biologicals are usually mild to moderate, but can sometimes be severe. The biologicals should be prescribed with caution, given that they have been on the market for a relatively short period, and because all forms of immune suppression carry an increased risk of oncologic degeneration. The guideline of the Dutch Society of Dermatology and Venereology states that the use of a biological may be considered when a patient cannot tolerate or is unresponsive to conventional systemic therapy, or has an increased risk of adverse events. Biologicals increase the number of options for treatment-resistant plaque psoriasis, which allows therapy to be tailored to the individual patient.
