To date, special attention in the treatment of psoriasis is paid to the comorbid background, since it is known that it can aggravate the course of psoriasis and affect the effectiveness of therapy. The purpose of psoriasis therapy is to achieve clean or almost clean skin, sustainable improvement of psoriatic arthritis, improving the quality of life, all this became possible with the advent of genetically engineered biological drugs. However, in the treatment of genetically engineered biological drugs there are “pain points”: primary inefficiency, “the effect of slipping”, the scheme of transition from one drug to another, the safety of the combined use of GIBP and system-based drugs, interruption of therapy.</span></p><p class="MsoNormal"><strong><span lang="EN-US">Objective.</span></strong><span lang="EN-US"> To study the therapeutic efficacy of ustekinumab in psoriasis patients with forced interruption of treatment, taking into account metabolic disorders.</span></p><p class="MsoNormal"><strong><span lang="EN-US">Materials and methods</span></strong><span lang="EN-US">. 52 patients with a diagnosis of plaque psoriasis receiving ustekinumab for 3 years were under observation, which were divided into 2 groups, depending on body weight and metabolic disorders.</span></p><p class="MsoNormal"><strong><span lang="EN-US">Results.</span></strong><span lang="EN-US"> More than 80 % of patients taking the drug at a dosage of 45 mg, and at a dosage of 90 mg, to week 12 therapy reached PASI 75. By week 24, the proportion of patients in group I who reached PASI 75 was 96.3 %, in group II — 88.0 %.</span></p><p class="MsoNormal"><span lang="EN-US">By week 48 PASI 75 reached 90.4 % patients: in group I — 100 % patients, in group II — 80.0 % patients.</span></p><p class="MsoNormal"><span lang="EN-US">At 76 weeks, patients were interrupted ustekinumab treatment in connection with the purchase of the drug. The duration of treatment interruption ranged 36 weeks. By week 112, 86.5 % patients in both groups had a relapse of psoriasis, which was assessed by the loss of the therapeutic response of PASI 75.</span></p><p class="MsoNormal"><span lang="EN-US">By week 124 (12 weeks after the resumption of therapy) 82.7 % patients reached PASI 75: in group I — 92.6 % patients, in group II — 72.0 % patients.</span></p><p class="MsoNormal"><span lang="EN-US">After 16 weeks (week 128), all patients 100 % achieved PASI 75 IN group I. In group II to week 128 PASI 75 was observed in 80 % patients.</span></p><p class="MsoNormal"><strong><span lang="EN-US">Conclusion</span></strong><span lang="EN-US">. With the resumption of treatment of patients with psoriasis with ustekinumab after a long interruption, there is a rapid and complete restoration of therapeutic effectiveness, however, in patients with psoriasis with metabolic disorders, there is a decrease in efficiency after the resumption of therapy in comparison with patients without abdominal obesity, which can determine the further strategy and tactics of management of such patients.</span></p>psoriasistherapeutic efficacyinterruption of therapyustekinumabпсориазтерапевтическая эффективностьпрерывание терапииустекинумаб[1.
