Update on the Management of Pediatric Psoriasis: An Italian Consensus.

INTRODUCTION: Psoriasis affects children with a considerable burden in early life. Treating pediatric psoriasis is challenging also because of the lack of updated specific guidelines. With the recent approval of several biologics for pediatric psoriasis and the ongoing COVID-19 pandemic, the management of young psoriatic patients is facing major changes. A revision of treatment recommendations is therefore needed. METHODS: In September 2021, a board of six Italian dermatologists convened to update treatment recommendations. The board issued evidence- and consensus-based statements covering relevant areas of pediatric psoriasis, namely: assessment of psoriasis severity, management of children with psoriasis, and treatment of pediatric psoriasis. To reach consensus, the statements were submitted to a panel of 24 experts in a Delphi process performed entirely via videoconference. A treatment algorithm was produced. RESULTS: There was full consensus that psoriasis severity is determined by the extension/severity of skin lesions, site of lesions, and impact on patient quality of life. Agreement was reached on the need for a multidisciplinary approach to pediatric psoriasis and the importance of patient/parents education. The relevance of vaccinations, including COVID-19 vaccination, for psoriatic children was acknowledged by all participants. Management issues that initially failed to reach consensus included the screening for psoriasis comorbidities and early treatment with biologics to prevent them and the use of telemedicine to facilitate patient follow-up. There was full consensus that topical corticosteroids are the first choice for the treatment of mild pediatric psoriasis, while phototherapy and systemic therapy are used in children with moderate-severe psoriasis. According to the proposed treatment algorithm, biologics are the first line of systemic therapy. CONCLUSIONS: Targeted systemic therapies are changing the treatment of moderate-severe pediatric psoriasis, while topical corticosteroids continue to be the first choice for mild disease. Children-centered research is needed to further improve the treatment of pediatric psoriasis.

Predictive factors of lack of response to adalimumab among bio-naive patients suffering from moderate-to severe psoriasis: analysis of a multicenter data collection in Italy.

INTRODUCTION: Efficacy of anti-TNF-a agents seems inferior to IL-17 and IL-23 inhibitors. Nevertheless, after biosimilars approval, anti TNF-a agents are recommended as first-line for psoriatic patients, for economic reasons. METHODS: Predictive factors of response or non-response to adalimumab in bionaive patients who started adalimumab (originator or biosimilar) over 12 years in 9 dermatologic centers in Italy. Effectiveness was assessed with Psoriasis Area and Severity Index (PASI75 and PASI90) at weeks 12, 24 and 48. Multiple logistic regressions were used for variables predicting clinical response; Kaplan-Meier survival curves and Cox regression for drug survival. RESULTS: The drug survival analysis showed reduced hazard ratio of overall discontinuation with male gender and scalp localization. In contrast, baseline PASI and genital psoriasis were significantly associated with increased risk of overall discontinuation. Predictive factors of non-response seemed elevated in patients with baseline PASI, older age groups, previously treated patients with phototherapy, females or patients with palmo-plantar while scalp psoriasis, previous cyclosporine and acitretin appeared as a positive predictive factor. CONCLUSIONS: This real-life analysis might be useful for clinicians in case of bio-naive patients with moderate-to-severe psoriasis and various comorbidities.

Novel combination for the treatment of acne differentiated based on gender: a new step towards personalized treatment.

BACKGROUND: The aim of this study is to evaluate efficacy and tolerability of a complete skin care line consisting of an oral supplement in two distinct formulations for males and females, and a topical cream device in the treatment of mild and moderate acne. Oral supplements contain biotin, probiotic, vitamin E, zinc, nicotinamide; in the formulation for males beta sitosterol and Boswellia serrata were added, the oral supplement for females contains myo-inositol and folic acid. The topical cream device is represented by the association between active plant agents (verbascoside, Ocimum gratissimum) and keratolytic molecules (salicylic acid, gluconolactone, complex alpha-hydroxy acids). METHODS: An equal number of male and female patients with mild to moderate acne were enrolled in a double-blinded clinical trial. Efficacy and tolerability evaluations were performed at week 4 (T1) and week 12 (T2) by Global acne Grading System (GAGs). RESULTS: Most of patients had satisfactory therapeutic response, in terms of GAGs reduction. All the four groups presented a statistically significant improvement of the mean GAGs at T2 but those assuming the oral supplement improved more, as expected. CONCLUSIONS: Our data suggest that this association can be considered a new effective option for mild and moderate acne. This therapeutic line differs from others in the gender matched oral treatment.
