Genetic variants in ERAP1 and ERAP2 associated with immune ‐mediated diseases influence protein expression and isoform profile
ConclusionsIn accordance with studies demonstrating that polymorphisms that increase aminopeptidase activity predispose to immune disease, the elevated risk also attributed to increased expression of ERAP1 and ERAP2 supports the therapeutic notion of aminopeptidase inhibition to treat AS and other ERAP associated conditions.This article is protected by copyright.

Validation of a definition for flare in patients with established gout
ConclusionsThe definition requiring the presence of ≥ 3 out of 4 patient‐reported criteria is now validated to be sensitive, specific, and accurate for gout flares (attacks) using an independent, large international sample. The availability of a validated gout flare definition will improve the ascertainment of an important clinical outcome in studies of gout.This article is protected by copyright. All rights reserved.

Dermatological Addendum to the 2012 International Chapel Hill Consensus Conference Nomenclature of Vasculitides
ConclusionsStandardized names and definitions are a prerequisite for developing validated classification and diagnostic criteria for cutaneous vasculitis. Accurate identification of specifically defined variants of systemic and skin‐limited vasculitides requires knowledgeable integration of clinical, laboratory and pathology data. The proposed nomenclature for vasculitides affecting the skin provides a standard framework for both clinicians and investigators.This article is protected by copyright. All rights reserved.
