Aspects concerning patient adherence to anti‑TNFα therapy in psoriasis: A decade of clinical experience

Abstract

Non-adherence to psoriasis treatment has an important impact in controlling chronic disease evolution and the occurrence of systemic comorbidities. Biologic therapy represents a revolutionary treatment, many of the undesirable psychological and socio-economical consequences of conventional topical or systemic therapies being avoided. Nevertheless, the discontinuation of biological therapy may occur due to facts related to the patient, to the lack of good communication between the patient and the physician or to the adverse or paradoxical reactions. We studied the non-adherence reasons to anti-TNFalpha agents (Infliximab, Adalimumab, Etanercept) used for treating 84 cases with moderate-severe psoriasis. The results of our study over the past 10 years showed a 76.2% adherence rate, lowest in patients treated with Etanercept (70.9%). Relative to the anti-TNF agent used, the highest adherence rate was recorded in Adalimumab (80.8%), followed by Infliximab (76.5%) and Etanercept (70.9%). We have noticed differences between the rates of adhesion to therapy with different anti-TNFalpha agents, but with no statistical significance. The main adverse effects that occurred during anti-TNFalpha therapy were: local reaction to the drug, mild infectious events, allergic reactions, cardiotoxicity, alopecia areata, pancreatitis, eosinophilia, thrombocytopenia. Anti-TNF therapy was discontinued in one case of endocarditis, one case with tuberculous laryngitis and another one with polydiscitis (Adalimumab), a case of colon cancer and one of pregnancy (Etanercept) and one paradoxical reaction (Infliximab).
