The safety of anti-interleukins monoclonal antibodies for the treatment of psoriasis.

: Psoriasis is a chronic inflammatory disease and affects about 10% of the world's population. Psoriasis is associated with a number of comorbidities. Biologic therapies for the treatment of moderate-severe plaque psoriasis include tumor necrosis factor α inhibitors (TNFi), and newer molecules targeting IL-12 and 23, blocking p40 subunit, or targeting subunit p19 of IL-23 and other molecules blocking IL-17A, or directed against the IL-17 receptor. : Anti-interleukin drugs show great improvement in disease control and on the other hand are not affected by important adverse reactions of older compounds. Approach to chronic disease affected patients, in particular, and to patients with multiple comorbidities is revolutionized by novel molecules that are safer and more manageable. : A recent work suggests that pro-fibrogenic cytokines, IL-17, might be important player of liver damage and even in regulation of obesity, diabetes, and non-alcoholic fatty liver disease (NAFLD) pathogenesis. Choosing to interfere with IL-23/Il-17 axis, definitely, is like acting against psoriatic march and in a parallel way against its comorbidities.
