Summary Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are related inflammatory rheumatic conditions affecting adults over the age of 50 years. Both conditions respond to initial glucocorticoid (GC) therapy. However, most patients require 12–36 months of a tapering steroid regime. Adverse events at 2 years are seen in up to 65% of patients with PMR and 86% of patients with GCA with over 50% developing serious events. There is also a high incidence of relapse in both diseases −40% within 2 years for GCA and 50% of patients with PMR at some point having a relapse. Effective steroid-sparing adjuvant therapies are urgently required especially in incomplete, poorly sustained or non-responders to glucocorticoids. In this case series, we found that Leflunomide is efficacious, with 22 out of our 23 patients exhibiting a complete or partial response. It was also steroid sparing and well tolerated. It may be a useful adjunctive agent in difficult-to-treat GCA and PMR. Prospective randomised controlled trials of Leflunomide in both GCA and PMR are now required.

Abstract Giant cell arteritis is the most frequent form of vasculitis characterized by a high risk of vascular thrombosis. Major complications are blindness and other vascular ischemia but bowel ischemic involvement is rare. Treatment is based on long-term steroid therapy with numerous side effects. The efficacy of immunosuppressive drugs like azathioprine methotrexate or anti-tumor necrosis factor antibodies appears to be too low to reduce the use of steroids. Th17 lymphocytes and interleukin-6...

Summary Giant cell arteriitis (GCA) is the most common of the vasculitis syndromes and, being a disease of the elderly, its incidence is increasing with the general ageing of the population. GCA is most feared for its early complications, namely blindness and stroke, resulting from inflammation and subsequent occlusion of ocular and extra cranial arteries, respectively. More recently, however, GCA has been recognised to also affect limb arteries and the aorta with a high prevalence. These newly ...

Scope and purpose GCA is the commonest of all the vasculitides. Visual loss occurs in up to one-fifth of patients, which may be preventable by prompt recognition and treatment [1,2]. The aim of these guidelines is to encourage the prompt diagnosis and management of GCA, with emphasis on the prevention of visual loss. Their scope is to provide evidence-based advice for the assessment and diagnosis of GCA, for initial and further management and for monitoring of disease activity, complications and...

Background Polymyalgia rheumatica (PMR) treatment is based on low-dose glucocorticoids. Glucocorticoid-sparing agents have also been tested. Our objective was to systematically examine the peer-reviewed literature on PMR therapy, particularly the optimal glucocorticoid type, starting doses, and subsequent reduction regimens as well as glucocorticoid-sparing medications. Methods We searched Cochrane Databases and MEDLINE (1957 through December 2008) for English-language articles on PMR treatment ...

Abstract Objective: To summarize the contribution of cytokines to pathogenesis, clinical manifestations and prognosis of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA). Methods: MEDLINE database search for studies published between 1980 and April 2008. Results: PMR and GCA are characterized by a hyperproduction of IL-6. The role of other circulating cytokines in their pathogenesis remains unclear. Cytokine mRNA in the arterial wall of GCA can distinguish different clinical subgroups...

PURPOSE OF THE REVIEW Polymyalgia rheumatica (PMR) is one of the most common inflammatory rheumatologic condition occurring in older adults. It is characterized by proximal pain and stiffness in the shoulders, neck, and/or pelvic girdle in individuals over 50 years of age along with evidence of an intense systemic inflammatory response. Although the above clinical symptoms are very characteristic for the condition, it can be mimicked by other autoimmune, infectious, malignant, and endocrine diso...

Improving understanding of the underlying pathophysiology of giant cell arteritis (GCA) is transforming clinical management by identifying novel avenues for targeted therapies. One key area of concern for both clinicians and patients with GCA is glucocorticoid (GC) morbidity. The first randomised controlled trials of targeted treatment to reduce cumulative GC use in GCA have been published, with tocilizumab, an interleukin (IL)-6 receptor inhibitor, now the first ever licensed treatment for GCA....
