Chronic hand eczema is frequent among patients with hand eczema accessing dermatology centres. Many patients were severe and refractory to standard therapy. The appropriate identification of hand eczema is the first step in implementing effective and efficient treatments.

Human serum paraoxonase-1 (PON-1) is a critical antioxidant defense system against lipid oxidation. Decreased PON-1 activity has been associated with systemic oxidative stress in several disease states. We conducted a systematic review and meta-analysis of plasma/serum concentrations of PON-1 paraoxonase and arylesterase activity in psoriasis, a chronic immune-mediated and inflammatory skin disease. The electronic databases PubMed, Web of Science, and Scopus were searched from inception to November 2021. In total, 14 studies in 691 psoriatic patients and 724 healthy controls were included in the meta-analysis. Serum paraoxonase activity was significantly lower in psoriatic patients (SMD = − 2.30, 95% CI − 3.17 to − 1.42; p < 0.001); however, no significant between-group differences were observed in serum arylesterase activity (SMD = − 0.34, 95% CI − 0.11 to 0.80; p = 0.14). The pooled SMD values were not substantially altered in sensitivity analysis. There was no publication bias. In conclusion, our meta-analysis has shown that serum paraoxonase, but not arylesterase, activity is significantly lower in psoriasis, suggesting an impaired antioxidant defense in these patients.

Health care spending in Italy is high and continues to increase; assessing the long-term health and economic outcomes of new therapies is essential. Atopic dermatitis (AD) is a chronic, pruritic, immune-mediated inflammatory dermatosis, a clinical condition that significantly affects patients’ quality of life at a high cost and requires continuous care. This retrospective study aimed to assess the direct cost and adverse drug reactions (ADRs) of Dupilumab and patients’ clinical outcomes. All AD patients treated with Dupilumab at the Sassari University Hospital, Italy, between January 2019 and December 2021 were included. Eczema Area Severity Index, Dermatology Life Quality Index, and Itch Numeric Rating Scale scores were measured. ADRs and drug expenses were analyzed. A statistically significant posttreatment improvement was observed for all the indices measured: EASI ( P < 0.0001 ), DLQI ( P < 0.0001 ), NRS ( P < 0.0001 ). The total expenditure for Dupilumab, in the observed period, amounted to € 589.748,66 for 1358 doses, and a positive correlation was shown between annual expenditure and delta percentage of variation pre- and posttreatment for the clinical parameters evaluated.
