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.

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.

ReviewCurrent treatment recommendations and considerations for cryopyrin-associated periodic syndrome.
Cryopyrin-associated periodic syndrome (CAPS) encompasses a spectrum of three phenotypes of increasing severity. The syndrome is due to dominant mutations in NLRP3, which encodes a key component of the innate immunity that regulates the secretion of IL-1β. ⋯ They have acceptable safety profiles but do have some differences. We review three drugs that are currently marketed for CAPS, give additional information for the practical use of these drugs, and provide some recommendations for management.

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.

ReviewIdiopathic recurrent pericarditis as an immune-mediated disease: current insights into pathogenesis and emerging treatment options.
Idiopathic recurrent pericarditis affects 30-50% of patients with a previous attack of pericarditis. The etiopathogenesis is incompletely understood and most cases remain idiopathic with a presumed immune-mediated pathogenesis. The mainstay of therapy is aspirin or a nonsteroidal anti-inflammatory drug plus colchicine and the possible adjunct of a low-to-moderate dose of a corticosteroid in more difficult cases. ⋯ The outcome of idiopathic recurrent pericarditis is good with a negligible risk of developing constrictive pericarditis. Thus, it is important to reassure patients on their prognosis, explaining the nature of the disease and the likely course. Moreover, therapeutic choices should include less toxic agents and favor cheaper drugs whenever possible.
