Atopic dermatitis is the most common chronic inflammatory skin disease in children and adolescents. The Korean Academy of Pediatric Allergy and Respiratory Disease published the Atopic Dermatitis Treatment Guideline in 2008, which has been helpful in atopic dermatitis treatment until now. Various reports on the development and effectiveness of new drugs have suggested that there is a need to develop and revise old treatment guidelines. Part 1 aimed to provide evidence-based recommendations for skin care management and topical treatment for atopic dermatitis. Part 2 focuses on systemic treatment, novel therapeutics, and adjuvant therapy. The goal of this guideline is intended to assist front-line doctors treating pediatric and adolescent atopic dermatitis patients make safer, more effective, and more rational decisions regarding systemic treatment, novel therapeutics, and adjuvant therapy by providing evidence-based recommendations with a clear level of evidence and benefit regarding treatment.

Atopic dermatitis (AD) is the most prevalent inflammatory skin condition, with approximately 80% of cases originating in childhood and some emerging in adulthood. In South Korea, the estimated prevalence of AD ranges between 10% and 20% in children and 1% and 3% in adults. Severe/recalcitrant AD manifests as a chronic, relapsing skin disorder, persisting with uncontrolled symptoms even after topical steroid treatment. Corticosteroids and systemic immunosuppression, conventionally the standard care for difficult-to-treat diseases, cause numerous undesirable side effects. When AD persists despite topical steroid application, systemic therapies like cyclosporine or systemic steroids become the second treatment strategy. The desire for targeted treatments, along with an enhanced understanding of AD’s pathophysiology, has spurred novel therapeutic development. Recent advances introduce novel systemic options, such as biological agents and small-molecule therapy, tailored to treat severe or recalcitrant AD. Notably, dupilumab, a monoclonal antibody inhibiting interleukin 4 and 13, marked a transformative breakthrough upon gaining approval from the U.S. Food and Drug Administration (FDA) in 2017, leading to a paradigm shift in the systemic treatment of AD. Furthermore, both dupilumab and Janus kinase inhibitors, including baricitinib, abrocitinib, and tofacitinib, now approved by the Korean FDA, have established their applicability in clinical practice. These innovative therapeutic agents have demonstrated favorable clinical outcomes, effectively addressing moderate to severe AD with fewer side reactions than those associated with previous systemic immunosuppressants. This review summarizes the latest advancements and evidence regarding systemic treatments for AD, including newly approved drugs in Korea.

Noncystic fibrosis bronchiectasis is a chronic respiratory disease that carries high socioeconomic and medical burdens and is caused by diverse respiratory illnesses. To improve clinical outcomes, early recognition, active treatment of exacerbations, and prevention of further exacerbations are essential. However, evidence for the treatment and prevention of acute exacerbation of noncystic fibrosis bronchiectasis, especially in children, is lacking. Therefore, the evidence- and consensus-based guidelines for medical and nonmedical treatment strategies for noncystic fibrosis bronchiectasis in children and adolescents were developed by the Korean Academy of Pediatric Allergy and Respiratory Disease using the methods recommended by the Grading of Recommendations Assessment, Development, and Evaluation working group with evidence published through July 2, 2020. This guideline encompasses evidence-based treatment recommendations as well as expert opinions, addressing crucial aspects of the treatment and management of non-cystic fibrosis bronchiectasis in children. This includes considerations for antibiotics and airway clearance strategies, particularly in areas where evidence may be limited. Large, well-designed, and controlled studies are required to accumulate further evidence of management strategies for noncystic fibrosis bronchiectasis in children and adolescents.
