A noteworthy number of NMSC were diagnosed in this Mediterranean population of patients exposed to high-dose UV treatment. A thorough risk-benefit evaluation should always be done before UV treatment and patients should be carefully monitored for skin cancer during and after treatment discontinuation.
Our study supports the role of TNF-alpha polymorphisms in predicting the response to anti-TNF-alpha agents. In particular, we found that the presence of -238G>A and -308G>A polymorphisms is associated with poor response to a 3-month therapy with etanercept. However, our data have yet to be validated in larger cohorts.
Our study showed that tacrolimus 0.1% ointment may be an efficacious and safe therapeutic opportunity in the treatment of nail psoriasis. Our data should be confirmed by a double-blind study with a larger sample of patients.
Although the heterogeneity of the therapeutic response to TNF-α blockers seems to be mainly due to genetic factors, several studies showed that a range of factors may influence it. The aim of our study was to investigate the impact of patients' demographic and clinical characteristics on primary response to an anti-TNF-α therapy in psoriatic patients. We retrospectively examined the relationship between various clinical and demographic features and response to treatment with etanercept, adalimumab, and infliximab, evaluated as PASI75 and average PASI improvement at weeks 12, 16, and 14, respectively. We analyzed data obtained from 199 patients. A better response to the treatment was significantly associated with male gender (OR = 2.59), coexistence of psoriatic arthritis (OR = 1.97), and PASI ≤15 at baseline (OR = 0.91). The present study supports that some clinical factors may be potential predictors of response to anti-TNF-α agents in psoriatic patients.
Background Psoriasis is an inflammatory chronic skin disease, characterized by redness (erythema), thickness and scaling of the skin, and by remittance/relapse phases of variable length. 1-3 It affects men and women in similar proportions, while the onset age is variable-though the disease most frequently occurs in young-adults. 4 The typical cutaneous manifestations of psoriasis and its chronic course significantly interfere with the affected
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
