Atopic dermatitis (AD) is a common inflammatory skin disorder which presents with recurrent eczematous lesions and itching. Its pathophysiology is complex and multifactorial. Alterations in cell-mediated immune responses, barrier dysfunction, environmental aspects and IgE-mediated hypersensitivity are all involved. This review aims to provide the clinician with an update on the impact that Th2 inflammation can have on growth and osteoimmunology. The potential adverse or protective effects brought on by the many therapies administered in this condition are also considered. Moreover, through this analysis, we aim to show how, by inhibiting the IL-4 and IL-13 signaling pathways—fundamental in the T helper 2 (Th2) immune axis and in AD pathogenesis—dupilumab may exert a protective role on growth and osteoimmunology in moderate-to-severe AD, particularly in young patients. This focus is essential for the correct, safe management of patients with Th2 inflammation.
