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 [F]-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.

Annals of the Rheumatic Diseases Jan 2024To develop treat-to-target (T2T) recommendations in giant cell arteritis (GCA) and polymyalgia rheumatica (PMR).
OBJECTIVES
To develop treat-to-target (T2T) recommendations in giant cell arteritis (GCA) and polymyalgia rheumatica (PMR).
METHODS
A systematic literature review was conducted to retrieve data on treatment targets and outcomes in GCA/PMR as well as to identify the evidence for the effectiveness of a T2T-based management approach in these diseases. Based on evidence and expert opinion, the task force (29 participants from 10 countries consisting of physicians, a healthcare professional and a patient) developed recommendations, with consensus obtained through voting. The final level of agreement was provided anonymously.
RESULTS
Five overarching principles and six-specific recommendations were formulated. Management of GCA and PMR should be based on shared decisions between patient and physician recognising the need for urgent treatment of GCA to avoid ischaemic complications, and it should aim at maximising health-related quality of life in both diseases. The treatment targets are achievement and maintenance of remission, as well as prevention of tissue ischaemia and vascular damage. Comorbidities need to be considered when assessing disease activity and selecting treatment.
CONCLUSION
These are the first T2T recommendations for GCA and PMR. Treatment targets, as well as strategies to assess, achieve and maintain these targets have been defined. The research agenda highlights the gaps in evidence and the need for future research.

Meta-Analysis Review
BACKGROUND
Several chronic inflammatory disorders, such as rheumatoid arthritis and systemic lupus erythematosus, have been linked to an increased risk of cerebrovascular accident (CVA), but the data on polymyalgia rheumatica (PMR) remains unclear.
MATERIALS AND METHODS
We conducted a systematic review and meta-analysis of observational studies that reported odds ratio, relative risk, hazard ratio, or standardized incidence ratio comparing the risk of CVA in patients with PMR versus non-PMR controls. Pooled risk ratio and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method of DerSimonian and Laird.
RESULTS
Three retrospective cohort studies and one cross-sectional study were identified and included in the data analysis. We found a significantly elevated CVA risk in patients with PMR, with the pooled risk ratio of 1.87 (95% CI, 1.43-2.43). The statistical heterogeneity was high, with an I2 of 91%.
CONCLUSIONS
Our study demonstrated a statistically significantly increased CVA risk among patients with PMR.

Review
Polymyalgia rheumatica (PMR) is the commonest inflammatory rheumatic disease affecting older people. The current mainstay of treatment is long-term oral glucocorticoid therapy. Management of these patients in clinical practice is often complicated by the presence of comorbidity. Comorbidity might be due to shared risk factors such as age, sex, or genetic background; to the presence of the disease itself; or to adverse effects of glucocorticoid therapy. Cardiovascular disease, osteoporosis/fracture, metabolic and ocular comorbidity are of particular interest to clinicians because of their relationship to glucocorticoid therapy and the relevance to clinical treatment decisions regarding glucocorticoid tapering. Patients at high risk of exacerbation of comorbidity by glucocorticoid therapy may be considered for adjunctive steroid-sparing therapies and thus may need specialist management. From a public health perspective, with the ageing population the prevalence of PMR is predicted to increase; accurate data on comorbidity will be needed for planning and delivery of healthcare services.

Review
BACKGROUND
Giant cell arteritis (GCA; sometimes referred to as temporal arteritis) and polymyalgia rheumatica (PMR) are common and interrelated inflammatory conditions that almost exclusively affect adults older than 50 years. There is a need for updated information on the epidemiology of these diseases.
OBJECTIVE
This systematic literature review (SLR) aims to summarize current evidence regarding the global incidence and prevalence of GCA and PMR.
METHODOLOGY
A systematic search of PubMed and Google Scholar databases from their inception dates to July 30, 2019 for relevant publications was performed. Studies that reported incidence and/or prevalence estimates for GCA and/or PMR were identified. When there were multiple studies of the same population, the most recent estimates were used. Details on source populations and case validation were systematically reviewed. Results were tabulated per region in the world.
RESULTS
Screening by 2 authors resulted in 2643 abstracts, of which 77 articles met the inclusion criteria. There were more studies on GCA compared to PMR, and more on incidence than on prevalence. Wide variations were found in study design and populations studied. Studies that included a thorough case validation tended to give lower estimates, in particular for PMR. The highest incidence per 100 000 aged ≥50 years of GCA was observed in studies from Scandinavia and the UK (14.6 to 43.6), and in Minnesota, USA (19.8 per 100 000). Corresponding estimates for Southern Europe were lower (1.1 to 11.1). Limited evidence indicates that GCA and PMR is less common in non-Caucasian populations. Prevalence estimates for PMR were ≥ 3 times higher than that of GCA in Caucasians.
CONCLUSION
This SLR provides up to date estimates of the occurrence of GCA and PMR in different populations around the world. The incidence of GCA is higher in populations of Northern European ancestry. Data on the epidemiology of PMR are more limited, with greater variation in incidence and prevalence estimates.

Meta-Analysis
OBJECTIVE
We aimed to analyse the association between infections and the subsequent risk of giant cell arteritis (GCA) and/or polymyalgia rheumatica (PMR) by a systematic review and a meta-analysis of observational studies.
METHODS
Two databases (Medline and Embase) were systematically reviewed. Epidemiological studies studying the association between any prior infection and the onset of GCA/PMR were eligible. Risk of bias was assessed using the Newcastle-Ottawa quality assessment scale. Outcomes and pooled statistics were reported as OR and their 95% CI.
RESULTS
Eleven studies (10 case-control studies and one cohort study) were analysed, seven of them were included in the meta-analysis. Eight were at low risk of bias. A positive and significant association was found between prior overall infections and prior (HZ) infections with pooled OR (95% CI) of 1.27 (1.18 to 1.37) and 1.20 (1.08 to 1.21), respectively. When analysed separately, hospital-treated and community-treated infections, were still significantly associated with the risk of GCA, but only when infections occurring within the year prior to diagnosis were considered (pooled OR (95% CI) 1.92 (1.67 to 2.21); 1.67 (1.54 to 1.82), respectively). This association was no longer found when infections occurring within the year prior to diagnosis were excluded.
CONCLUSION
Our study showed a positive association between the risk of GCA and prior overall infections (occurring in the year before), and prior HZ infections. Infections might be the reflect of an altered immunity of GCA patients or trigger the disease. However, reverse causation cannot be excluded.CRD42023404089.

Meta-Analysis Review
PURPOSE
Polymyalgia rheumatica (PMR) can be difficult to diagnose. Whole-body [18F]FDG-PET/CT allows for a comprehensive evaluation of all relevant articular and extra-articular structures affected by PMR. We aimed to summarize current evidence on the diagnostic value of [18F]FDG-PET/CT for a diagnosis of PMR.
METHODS
PubMed/MEDLINE and the Cochrane Library database were searched from inception through May 31, 2020. Studies containing patients with PMR who underwent [18F]FDG-PET/CT were included. Screening and full-text review were performed by 3 investigators and data extraction by 2 investigators. Risk of bias was examined with the QUADAS-2 tool. Diagnostic test meta-analysis was performed with a bivariate model.
RESULTS
Twenty studies were included in the systematic review, of which 9 studies (n = 636 patients) were eligible for meta-analysis. [18F]FDG positivity at the following sites was associated with a diagnosis of PMR: interspinous bursae (positive likelihood ratio (LR+) 4.00; 95% CI 1.84-8.71), hips (LR+ 2.91; 95% CI 2.09-4.05), ischial tuberosities (LR+ 2.86; 95% CI 1.91-4.28), shoulders (LR+ 2.57; 95% CI 1.24-5.32) and sternoclavicular joints (LR+ 2.31; 95% CI 1.33-4.02). Negative likelihood ratios (LR-) for these sites, as well as the greater trochanters, were all less than 0.50. Composite [18F]FDG-PET/CT scores, as reported in 3 studies, provided a pooled LR+ of 3.91 (95% CI 2.42-6.32) and LR- of 0.19 (95% CI 0.10-0.36). Moderate to high heterogeneity was observed across the studies, mainly due to differences in patient selection, scanning procedures and/or interpretation criteria.
CONCLUSION
Significant [18F]FDG uptake at a combination of anatomic sites is informative for a diagnosis of PMR. [18F]FDG-PET/CT might be an important diagnostic tool in patients with suspected PMR. This study also highlights the need for adherence to published procedural recommendations and standardized interpretation criteria for the use of [18F]FDG-PET/CT in PMR.

Review
OBJECTIVE
To systematically identify and appraise the existing literature on the association between polymyalgia rheumatica (PMR) and vascular disease.
METHODS
The Medline, Embase, CINAHL, and Cochrane databases were searched from inception to September 2010. Search criteria included observational studies containing patients with isolated PMR reporting on a vascular outcome. Data were extracted and articles were assessed for quality.
RESULTS
The database search identified 545 articles. Eight articles reporting on 7 unique studies were included in the final review. Four studies reported on vascular mortality and 3 studies reported on other vascular outcomes. Four of the studies reported statistically significant positive associations between PMR and vascular disease and 3 studies reported no statistically significant results. The heterogeneity of the results was investigated; the strongest explanatory variable was that 2 of 3 studies that reported nonsignificant results were prospective, whereas all of those studies reporting significant results were retrospective.
CONCLUSION
There is some evidence to suggest that, like other inflammatory rheumatic disorders, PMR may be linked to an increased risk of vascular disease. Further studies are required to quantify the level of risk to determine whether patients with PMR should be actively screened for cardiovascular disease and its risk factors.

Meta-Analysis
OBJECTIVES
To determine the prevalence and predictors of subclinical giant cell arteritis (GCA) in patients with newly diagnosed polymyalgia rheumatica (PMR).
METHODS
PubMed, Embase, and Web of Science Core Collection were systematically searched (date of last search July 14, 2021) for any published information on any consecutively recruited cohort reporting the prevalence of GCA in steroid-naïve patients with PMR without cranial or ischemic symptoms. We combined prevalences across populations in a random-effect meta-analysis. Potential predictors of subclinical GCA were identified by mixed-effect logistic regression using individual patient data (IPD) from cohorts screened with PET/(CT).
RESULTS
We included 13 cohorts with 566 patients from studies published between 1965 to 2020. Subclinical GCA was diagnosed by temporal artery biopsy in three studies, ultrasound in three studies, and PET/(CT) in seven studies. The pooled prevalence of subclinical GCA across all studies was 23% (95% CI 14%-36%, I=84%) for any screening method and 29% in the studies using PET/(CT) (95% CI 13%-53%, I=85%) (n=266 patients). For seven cohorts we obtained IPD for 243 patients screened with PET/(CT). Inflammatory back pain (OR 2.73, 1.32-5.64), absence of lower limb pain (OR 2.35, 1.05-5.26), female sex (OR 2.31, 1.17-4.58), temperature >37° (OR 1.83, 0.90-3.71), weight loss (OR 1.83, 0.96-3.51), thrombocyte count (OR 1.51, 1.05-2.18), and haemoglobin level (OR 0.80, 0.64-1.00) were most strongly associated with subclinical GCA in the univariable analysis but not C-reactive protein (OR 1.00, 1.00-1.01) or erythrocyte sedimentation rate (OR 1.01, 1.00-1.02). A prediction model calculated from these variables had an area under the curve of 0.66 (95% CI 0.55-0.75).
CONCLUSION
More than a quarter of patients with PMR may have subclinical GCA. The prediction model from the most extensive IPD set has only modest diagnostic accuracy. Hence, a paradigm shift in the assessment of PMR patients in favour of implementing imaging studies should be discussed.

Meta-Analysis Review
INTRODUCTION
Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) can be concurrent diseases. We aimed to estimate the point-prevalence of concurrent GCA and PMR. Additionally, an incidence rate (IR) of GCA presenting after PMR diagnosis in patients was estimated.
METHODS
Two authors performed a systematic literature search, data extraction and risk of bias assessment independently. Studies assessing cohorts of patients presenting with both GCA and PMR were included. The outcomes were point-prevalence of concurrent GCA and PMR and IR for development of GCA after PMR diagnosis. A meta-analysis was performed to calculate a pooled prevalence of concurrent PMR and GCA.
RESULTS
We identified 29 studies investigating concurrent GCA and PMR. Only two studies applied imaging systematically to diagnose GCA and none to diagnose PMR. GCA presenting after PMR diagnosis was assessed in 12 studies but imaging was not applied systematically. The point-prevalence of concurrent GCA present at PMR diagnosis ranged from 6%-66%. The pooled estimate of the point-prevalence from the meta-analysis was 22%. The point-prevalence of PMR present at GCA diagnosis ranged from 16%-65%. The pooled estimate of the point-prevalence from the meta-analysis was 42%. The IR ranged between 2-78 cases of GCA presenting after PMR per 1000 person-years.
CONCLUSION
This review and meta-analysis support that concurrent GCA and PMR is frequently present at the time of diagnosis. Additionally, we present the current evidence of GCA presenting in patients after PMR diagnosis. These results emphasize the need for studies applying imaging modalities to diagnose GCA.
