Takayasu-Onishi arteritis (T.O.) is similar to Hutchison-Horton arteritis (H.H.) on histological, clinical, laboratory, and pathogenetic grounds. Both probably depend on immunitary dysreactivity, their different clinical expression being attributable to differences in the district involved and the age of the subject. Both are preceded or accompanied by rheumatism. An interesting relation can be made out between temporal arteritis and "rheumatic polymyalgia" or, more aptly, "rhizomelic polymyalgia" (Ballabio, 1975). The latter (of rheumatic origin) may accompany arteritis - Hamrin, indeed, has suggested their unification in the description "arteritic polymyalgia". It is uncertain whether vasculopathy in the course of collagen disease, rheumatic arteritis, and polyarteritis nodosa can be identified with T.O., even though a common immunological basis can be made out. The difference between T.O. and thromboangiitis obliterans, on the other hand, is quite clear at the present time.

Temporal arteritis (also known as Horton's or giant cell arteritis) is a panarteritis of the large and medium-calibre cranial vessels. An account is given of its epidemiological, clinical and anatomopathological aspects and its involvement of the locomotor apparatus (Horton's rheumatism). Reference is also made to the close relationship between temporal arteritis and pulseless disease. Some workers are of the opinion that they share the same aetiology, and that their clinical expression in different areas is dictated by age and constitutional factors.

Polymyalgia rheumatica (PMR) is a common disorder in the elderly population. The diagnosis is based upon recognition of a clinical syndrome, consisting of pain and stiffness in the shoulder and pelvic girdle, muscle tenderness of the upper and lower limbs and nonspecific somatic complaints. In addition, in most cases the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) concentration are highly elevated. Although PMR and giant cell arteritis (GCA) are commonly regarded as two clinical variations of the same disease, their clinical picture is quite different. Whilst in PMR the musculoskeletal symptoms predominate, the major features of GCA are arterial inflammation and its consequences, which suggests clinical and pathological discrepancies between the two syndromes and important differences with respect to morbidity and mortality. The prognosis of correctly diagnosed PMR is excellent. It is well known that corticosteroid therapy in PMR usually leads to rapid and dramatic improvement of patients' complaints and returns them to previous functional status. However, prolonged corticosteroid treatment, sometimes for several years, may be necessary to maintain clinical improvement. Despite all the knowledge about the beneficial effects of corticosteroid treatment, data concerning the optimal dosage regimen are lacking. Long-term corticosteroid use can be associated with various adverse events, of which induction of osteoporosis, diabetes mellitus and infection among the worst. A Corticosteroid Side Effect Questionnaire has been shown to dose-dependently detect adverse effects perceived by patients. The European League Against Rheumatism (EULAR) response criteria for PMR comprise a core set of markers for monitoring therapeutic responses in PMR, namely ESR or CRP, the visual analogue scale of patient's pain and physician's global assessment, as well as morning stiffness and the ability to elevate the upper limbs. The PMR-disease activity score has been developed on the basis of EULAR response criteria as a means of expressing disease activity as an absolute number. A score <7 indicates low disease activity, scores 7-17 suggest medium activity, and a score >17 is indicative of high disease activity. The PMR-disease activity score has been proven to be highly correlated with patient's global assessment, patient satisfaction and ESR. It provides an easily applicable and valid tool for disease activity monitoring in patients with PMR. Improved knowledge of disease activity processes, exact monitoring of disease activity and treatment responses, and increased risk-estimation of treatment schedules should ultimately improve the care of patients with PMR.

Giant cell arteritis is the most common systemic vasculitis and affects large and medium-sized vessels. Glucocorticoids are the current standard in the therapy of giant cell arteritis. To reduce the glucocorticoid dose the European League Against Rheumatism (EULAR) suggests the addition of disease-modifying antirheumatic drugs. Of these, methotrexate represents the best investigated drug; possible alternatives include azathioprine, tumor necrosis factor-alpha inhibitors and cyclophosphamide.

Vasculitis is still being classified according the criteria of the American College of Rheumatology and the Chapel Hill Consensus Conference Definitions. Diagnostic criteria are currently being established. The classification criteria are based on the size of the inflamed blood vessel (e.g. large vessel vasculitis with inflammation of the aorta and its branches), clinical symptoms and findings (such as cephalalgia in giant cell arteritis) and histological findings. In recent years a definition of disease stages and activity has been established and a number of controlled trials have been carried out in order to provide evidence-based stage and activity adapted therapy regimens. Recommendations for the management of vasculitis have been published in 2009 by EULAR (European League Against Rheumatism). This article gives a review of the classification of vasculitis and summarizes the current European guidelines on management.

Polymyalgia rheumatica is a chronic, inflammatory disorder of unknown cause that affects people over age 50 years. Classic symptoms include pain and long-term morning stiffness of the neck, shoulders, hips, upper arms, and thighs. Although markers of inflammation are often raised, no specific laboratory test exists for the disorder and the diagnosis is based on clinical assessment. Provisional classification criteria were published in April, 2012, by a collaborative initiative of the European League Against Rheumatism and the American College of Rheumatology. Several other disorders can mimic polymyalgia rheumatica. In particular, clinical manifestations can be difficult to differentiate from other forms of inflammatory arthritis such as spondyloarthritis and rheumatoid arthritis. Imaging studies such as ultrasonography and MRI typically show a predominantly periarticular inflammatory process. A subset of patients has an associated inflammatory vasculopathy affecting large arteries (giant cell arteritis). The standard treatment is low-dose glucocorticoids, which provide symptomatic relief for most patients. However, disease relapses are common, and treatment with glucocorticoids is associated with substantial morbidity. Improved understanding of disease pathogenesis might allow for more targeted immunotherapy.

Polymyalgia rheumatica (PMR) is a common inflammatory condition that often affects people over the age of 50 years. Characteristic symptoms are shoulder and hip girdle pain and prolonged morning stiffness. Markers of inflammation are often elevated. Clinicians are often faced with the challenge of distinguishing PMR from other conditions, particularly rheumatoid arthritis and spondyloarthropathy that can mimic symptoms of PMR in older people. Additionally, there is an association between PMR and giant cell arteritis, a common large-vessel vasculitis which also affects people over the age of 50 years. Imaging of the large vessels in asymptomatic patients with PMR often reveals findings of subclinical vasculitis. Presently, there are no tests that are specific for the diagnosis of PMR and clinicians rely on a combination of history, physical examination, laboratory tests and imaging studies to make a diagnosis. A recent undertaking by the European League Against Rheumatism/American College of Rheumatology has led to the publication of provisional classification criteria of PMR. Ultrasonography, which is being increasingly used by rheumatologists, can greatly aid in the diagnosis of PMR and often shows changes of synovitis and tenosynovitis. Treatment consists of low doses of glucocorticoids which are associated with morbidity. Evaluation of newer biologic therapies targeting inflammatory cytokines is underway. Despite treatment, relapses are common.

Polymyalgia rheumatica (PMR) is a chronic inflammatory disorder of unknown cause characterised by the subacute onset of shoulder and pelvic girdle pain, and early morning stiffness in men and women over the age of 50 years. Due to the lack of a gold standard investigation, diagnosis is based on a clinical construct and laboratory evidence of inflammation. Heterogeneity in the clinical presentation and disease course of PMR has long been recognised. Aside from the evolution of alternative diagnoses, such as late-onset rheumatoid arthritis, concomitant giant cell arteritis is also recognised in 16-21% of cases. In 2012, revised classification criteria were released by the European League Against Rheumatism and American College of Rheumatology in order to identify a more homogeneous population upon which future studies could be based. In this article, we aim to provide an updated perspective on the pathogenesis and diagnosis of PMR, with particular focus on imaging modalities, such as ultrasound and whole body positron emission tomography/computed tomography, which have advanced our current understanding of this disease. Future treatment directions, based on recognition of the key cytokines involved in PMR, will also be explored.

Polymyalgia rheumatica is an inflammatory musculoskeletal disorder of people aged 50 years or over, characterised by pain, aching and morning stiffness in the shoulder girdle and often hip girdle and neck. Marked systemic inflammation and rapid response to corticosteroid therapy are characteristic features. Giant cell arteritis is a well-known association of polymyalgia rheumatica. Recent clinical evidence and scientific results in the field have provided new challenges for rheumatologists. Besides the aspecific - although characteristic - proximal syndrome, less well recognizable and more variable distal musculoskeletal manifestations were observed. Magnetic resonance and ultrasound studies showed mild, remitting and non-erosive synovitis, with dominating inflammation of the extraarticular synovial structures. As no pathognostic sign is known, the diagnosis of polymyalgia rheumatica is based on its differential diagnosis, differentiation from the polymyalgia mimics; particularly from elderly onset inflammatory arthritides, such as elderly onset rheumatoid arthritis and late onset seronegative spondylarthritis. In 2012 the international polymyalgia rheumatica work group under the guidance of the American College of Rheumatology and European League Against Rheumatism elaborated new classification criteria, the scoring algorythm of which is based on clinical symptoms, with ultrasonography increasing the specificity. Corticosteroids remain the cornerstone of the therapy of polymyalgia rheumatica. No effective steroid-sparing drug has been found to date. Corticosteroids are generally needed for 1-1.5 years, though some patients have a chronic-relapsing course and require corticosteroids for several years. Well known corticosteroid-related side effects (diabetes, hypertension, hyperlipidaemia and osteoporosis) cause significant morbidity and economic burden on the society. Novel therapeautic approaches are on trial. Early recognition of the disease, early start of corticosteroids and a well-defined course, prevention and management of side effects are everyday tasks for rheumatologists and family doctors. Knowledge of polymyalgia rheumatica is essential for all medical specialties.

To develop evidence-based recommendations for the use of imaging modalities in primary large vessel vasculitis (LVV) including giant cell arteritis (GCA) and Takayasu arteritis (TAK). European League Against Rheumatism (EULAR) standardised operating procedures were followed. A systematic literature review was conducted to retrieve data on the role of imaging modalities including ultrasound, MRI, CT and [18F]-fluorodeoxyglucose positron emission tomography (PET) in LVV. Based on evidence and expert opinion, the task force consisting of 20 physicians, healthcare professionals and patients from 10 EULAR countries developed recommendations, with consensus obtained through voting. The final level of agreement was voted anonymously. A total of 12 recommendations have been formulated. The task force recommends an early imaging test in patients with suspected LVV, with ultrasound and MRI being the first choices in GCA and TAK, respectively. CT or PET may be used alternatively. In case the diagnosis is still in question after clinical examination and imaging, additional investigations including temporal artery biopsy and/or additional imaging are required. In patients with a suspected flare, imaging might help to better assess disease activity. The frequency and choice of imaging modalities for long-term monitoring of structural damage remains an individual decision; close monitoring for aortic aneurysms should be conducted in patients at risk for this complication. All imaging should be performed by a trained specialist using appropriate operational procedures and settings. These are the first EULAR recommendations providing up-to-date guidance for the role of imaging in the diagnosis and monitoring of patients with (suspected) LVV.
