Abstract
Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are two closely related diseases in people aged 50 years and older, which are more frequently observed in Western countries. Despite being common entities, concern still exists about the epidemiology, pathogenesis, and diagnosis of both entities. New imaging techniques, such as 18 fluorodeoxyglucose-positron emission tomography, have proved to be useful in detecting large-vessel involvement in GCA. Corticosteroids are the cornerstone of the therapy in GCA and PMR. Relapses are frequent in these conditions. Unlike methotrexate and tumor necrosis factor-α antagonists, anti-interleukin-6 receptor therapy appears to be useful in patients with GCA and PMR who are refractory to corticosteroids. This review summarizes recent studies on GCA and PMR.

Ann Rheum Dis. 2013;72:1882–6. PTPN22 R620W functional variant has been implicated in the susceptibility to several autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus. The present study also confirms its implication in GCA. These findings indicate that PTPN22 may represent a common pathway for different autoimmune diseases.

[Epub ahead of print] Interesting study that indicates that color duplex US of the temporal artery does not improve the sensitive of TAB to make a diagnosis of GCA. The results, rather than reducing the potential usefulness of color duplex US for the diagnosis of GCA, highlight the relevance of an adequate clinical examination to proceed to TAB when GCA is suspected.

In this exhaustive review the authors assessed the qualitative and quantitative methods used for the assessment of vasculitis by 18-FDG-PET. They concluded that the qualitative methods may be more specific than semiquantitative ones, but they have lower sensitivity.

[Epub ahead of print] The clinical spectrum of patients with large vessel involvement in the setting of GCA is different from that found in patients presenting with typical cranial manifestations of GCA. Patients with large vessel involvement have less frequency of severe visual complication but they experience more relapses and have higher corticosteroid requirements than those presenting with classic cranial manifestations.
