RESUMO
Introduction: Omalizumab, which is a recombinant, humanised anti-immunoglobulin-E antibody, is the only approved drug for antihistamine refractory chronic spontaneous urticaria (CSU). It has been reported that it is an effective and safe drug, but the data about long-term effectiveness are still lacking. Aim: To perform a retrospective analysis of the patients with CSU treated with omalizumab at the dermatology department to assess effectiveness of omalizumab therapy in the single centre in Poland. Material and methods: A two-and-a-half-year retrospective analysis of patients with CSU undergoing the therapy with omalizumab was conducted. Patients' data were analysed for many factors such as age, gender, severity indexes (UAS7, DLQI), duration and effects of the treatment used. Results: Sixty-one patients with CSU have been treated with omalizumab in the drug program. The number of female patients - 42 (68.9%) significantly dominated over the number of male patients - 19 (31.1%). The mean UAS7 during the first course of treatment declined from 33.2 to 2.8, during the second from 30.9 to 1.7 and during the third 32.7 to 2.5. In case of DLQI the mean scores decrease from 18 to 2.1 in the first cycle, from 16.9 to 1.9 in the second and from 18.6 to 1.1 in the third. Conclusions: Our study confirmed that omalizumab is an effective medicine in a long-term treatment which improves a physical as well as psychological condition of the patients with antihistamine-resistant CSU. To our knowledge, it is the first study in Poland that presents omalizumab effectiveness during three courses of treatment.
RESUMO
The growing use of biological drugs in immune-mediated chronic diseases has undoubtedly revolutionized their treatment. Yet, the topic of vaccinations in this group of patients still raises many concerns and implies many therapeutic problems that require discussion and standardization of management. The aim of this literature review is to present current knowledge regarding safety and efficacy of vaccinations in dermatological and rheumatological patients treated with biological drugs and JAK inhibitors. Additionally, this article provides recommendation from experts of the Polish Dermatological Society about proper use of vaccinations during therapy with biologics. Generally, all live attenuated vaccines are contraindicated during immunosuppressive/immunomodulatory therapy. If there is need, they should be administered long enough prior to the therapy or after cessation. Yet, inactivated vaccines mostly can be safely used, but the problem in this case is the effectiveness of the vaccination. Most studies report that the immune response in patients on biologics after administration of different inactivated vaccines is similar to or even better than in the control group. Thus, the importance of vaccination among patients on biologics must be emphasized to reduce omissions and the fear of possible side effects or insufficient post-vaccination response.
