Randomized Controlled Trial
Efficacy and safety of ixekizumab in a phase III, randomized, double-blind, placebo-controlled study in paediatric patients with moderate-to-severe plaque psoriasis (IXORA-PEDS).
Plaque psoriasis affects children and adults, but treatment options for paediatric psoriasis are limited. ⋯ IXE was superior to placebo in the treatment of moderate-to-severe paediatric psoriasis, and the safety profile was generally consistent with that observed in adults. What is already known about this topic? Paediatric psoriasis affects approximately 1% of children and can negatively impact health-related quality of life. Treatment options for paediatric psoriasis are typically limited to off-label treatments and approved systemic biologics. Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for moderate-to-severe plaque psoriasis in adults and was recently approved by the US Food and Drug Administration for moderate-to-severe paediatric psoriasis. What does this study add? Ixekizumab resulted in rapid and statistically significant improvements over placebo in skin involvement, itch and health-related quality of life, which persisted through 48 weeks of treatment in paediatric patients with moderate-to-severe plaque psoriasis. The safety profile of ixekizumab was generally consistent with that seen in adults. Ixekizumab may be an additional potential therapeutic option and an additional class of biologic therapy (interleukin-17A antagonist) for the treatment of moderate-to-severe paediatric psoriasis.

Randomized Controlled Trial
Baricitinib in patients with moderate-to-severe atopic dermatitis and inadequate response to topical corticosteroids: results from two randomized monotherapy phase III trials.
Baricitinib, an oral selective Janus kinase 1 and 2 inhibitor, effectively reduced atopic dermatitis (AD) severity in a phase II study with concomitant topical corticosteroids. ⋯ Baricitinib improved clinical signs and symptoms in patients with moderate-to-severe AD within 16 weeks of treatment and induced rapid reduction of itch. The safety profile remained consistent with prior findings from baricitinib clinical development in AD, with no new safety concerns.

Acne vulgaris is a common skin condition affecting approximately 95% of adolescents to some extent. First-line treatments are topical preparations but nonadherence is common. A substantial proportion of patients take long courses of oral antibiotics, associated with antibiotic resistance. ⋯ People with acne need support to manage their condition effectively, particularly a better understanding of different topicals, how to use them and how to avoid side-effects. Unrealistic expectations about the onset of action of treatments appears to be a common cause of frustration and nonadherence. Directing people towards accessible evidence-based information is crucial. What's already known about this topic? There is a common perception that acne is a short-term condition that will resolve without treatment. Previous research has shown that nonadherence to topical treatments is common and that oral antibiotics are the most commonly prescribed treatment for acne in the U.K. Further research is needed to understand how young people perceive acne treatments and the implications of this for treatment adherence and self-management. What does this study add? People often said they had tried all available topical preparations for acne, but seemed confused between cosmetic and pharmaceutical treatments. People seemed unsure how to use topical treatments 'properly' or how to avoid side-effects. This was rarely discussed with health professionals. People's perception of acne as a short-term condition appeared to influence their expectations around onset of action of treatment and their views about its effectiveness and necessity. What are the clinical implications of the work? The perception of acne as a short-term condition has implications for self-management and motivation to seek and adhere to treatments. Providing advice about onset of action of treatments and how to prevent side-effects is crucial, including directing people towards accessible, written, evidence-based information. People's confusion about the different topical treatments available may be alleviated by such information, or by encouraging photos or other recordings of treatments tried and for how long.
