Editorial ReviewUtilizing social networks, blogging and YouTube in allergy and immunology practices.
Online social networks are used to connect with friends and family members, and increasingly, to stay up-to-date with the latest news and developments in allergy and immunology. As communication is a central part of healthcare delivery, the utilization of such networking channels in allergy and immunology will continue to grow. ⋯ There is a paucity of information in the literature on how social network interventions affect patient outcomes. The allergy and immunology community should direct future studies towards investigating how the use of social networks and other technology tools and services can improve patient care.

ReviewThe evolution of allergen and non-specific immunotherapy: past achievements, current applications and future outlook.
Recent epidemiological studies estimated that more than 30% of European suffer from allergic rhinitis or conjunctivitis, while up to 20% suffer from asthma and 15% from allergic skin conditions, while for many other regions the prevalence is increasing. Allergen immunotherapy represents the only available treatment that can modify the allergic disease process, and thus is worth considering as a treatment in affected individuals. A beneficial effect of allergen immunotherapy has been shown in both adults and children affected by allergic rhinitis, allergic conjunctivitis, allergic asthma and hymenoptera venom allergy. The present study represents an overview on allergen immunotherapy, focusing on the principal aspects of the use of immunotherapy in the past, its recent clinical applications and future outlook.

ReviewScientific rationale behind the development and approval of biosimilar infliximab (CT-P13) in Europe.
Biosimilars are drugs developed to be highly similar to their originator biologic (or 'reference medicinal product') with no clinically meaningful differences in purity, efficacy or safety. Production of biologics and biosimilars is highly complex and sensitive, with any change in manufacturing process having a potential impact on efficacy and safety. ⋯ The scientific rationale underlying the regulatory comparability exercise for process-changed reference medicinal products and biosimilars is also discussed, as is the issue of 'switchability' from a reference medicinal product to its biosimilar. CT-P13 (Remsima(®), Inflectra(®)), a biosimilar of infliximab, is used as a case study to discuss these issues.

Psoriasis is a chronic inflammatory disease with a multifactorial origin that appears in patients with genetic predisposition and is induced by environmental factors, and characterized by alterations in the innate and adaptive immunity. IL-17A is one of the specific cytokines involved in the pathogenesis of psoriasis and its inhibition is highly effective in the treatment of patients with moderate and severe psoriasis. Secukinumab is a monoclonal antibody that specifically binds to IL-17A and inhibits the interaction to its receptor, and it has demonstrated its efficacy and safety in the treatment of psoriasis. ⋯ This was especially the case for Candida infections, which were more common in the secukinumab group (4.7% with secukinumab 300 mg and 2.3% with secukinumab 150 mg), but all cases were resolved with conventional treatment. Secukinumab is a well-tolerated treatment that has demonstrated efficacy in treating moderate-to-severe plaque psoriasis. Nevertheless, long-term studies are necessary to confirm Phase II and Phase III data.

ReviewThe histiocytosis Erdheim-Chester disease is an inflammatory myeloid neoplasm.
Erdheim-Chester disease (ECD) is a rare, non-Langerhans histiocytosis, characterized by the infiltration of tissues by foamy CD68(+)CD1a(-) histiocytes. (99)Technetium bone scintigraphy revealing almost constant tracer uptake by the long bones is highly suggestive of ECD, and a 'hairy kidney' appearance on abdominal computed tomography scan is observed in about half of all ECD cases. CNS involvement is a strong prognostic factor and independent predictor of death. IFN-α seems to be the best initial treatment for ECD. ⋯ More than 30 patients worldwide harboring this mutation and displaying multisystemic, refractory ECD have been treated with vemurafenib, a BRAF inhibitor, which has proven highly beneficial. Other recurrent mutations of the MAPK and PIK3 pathways (NRAS, PIK3CA) have recently been described. These mutations should lead to a new classification of histiocytic disorders such that Langerhans cell histiocytosis and ECD are classified as inflammatory myeloid neoplasms.
