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.

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.

Meta-Analysis Review
Several chronic inflammatory disorders, such as rheumatoid arthritis and systemic lupus erythematosus, are associated with an increased risk of coronary artery disease (CAD) as a result of accelerated atherosclerosis. However, the data on CAD risk of polymyalgia rheumatica (PMR), one of the most common chronic inflammatory disorders in older adults, remain unclear due to limited number of epidemiological studies. To further investigate this possible association, this systematic review and meta-analysis of observational studies was performed to compare the risk of CAD in patients with PMR versus subjects without it. Published studies indexed in MEDLINE and EMBASE were searched from inception to April 2016 using the terms "polymyalgia rheumatica" combined with the terms for CAD. The inclusion criteria were: (1) observational studies published as original studies to evaluate the risk of CAD among patients with PMR; (2) published odds ratios, relative risk or hazard ratio or standardized incidence ratio with 95 % confidence intervals (CI) in the studies; and (3) subjects without PMR were used as comparators in cohort studies and cross-sectional studies, while subjects without CAD were used as comparators in case-control studies. Point estimates and standard errors were extracted from individual studies and were combined by the generic inverse variance method of DerSimonian and Laird. Four studies with 34,569 patients with PMR were identified and included in this meta-analysis. The pooled risk ratio of CAD in patients with PMR was 1.72 (95 % CI 1.21-2.45). The statistical heterogeneity of this meta-analysis was high with an I of 97 %.

Review
BACKGROUND
Three checkpoint inhibitor drugs have been approved by the US Food and Drug Administration for use in specific types of cancers. While the results are promising, severe immunotherapy-related adverse events (irAEs) have been reported.
OBJECTIVES
To conduct a systematic review of case reports describing the occurrence of irAEs in patients with cancer following checkpoint blockade therapy, primarily to identify potentially unrecognized or unusual clinical findings and toxicity.
DATA SOURCES
We searched Medline, EMBASE, Web of Science, PubMed ePubs, and Cochrane CENTRAL with no restriction through August 2015.
STUDY SELECTION
Studies reporting cases of cancer develop irAEs following treatment with anti CTLA-4 (ipilimumab) or anti PD-1 (nivolumab or pembrolizumab) antibodies were included.
DATA EXTRACTION
We extracted data on patient characteristics, irAEs characteristics, how irAEs were managed, and their outcomes.
DATA SYNTHESIS
191 publications met inclusion criteria, reporting on 251 cases. Most patients had metastatic melanoma (95.6%), and the majority were treated with ipilimumab (93.2%). Autoimmune colitis, hepatitis, endocrinopathies, and cutaneous irAEs were the most frequently reported irAEs in ipilimumab treated patients. A broad spectrum of toxicities were reported for almost every body system. Moreover, well-defined diseases such as sarcoidosis, polyarthritis, polymyalgia rheumatica/arteritis, lupus, celiac disease, dermatomyositis, and Vogt-Koyanagi-like syndrome were reported. The most frequent irAEs reported with anti-PD1 agents were dermatitis for pembrolizumab, and thyroid disease and pneumonitis for nivolumab. Complete resolution of adverse events occurred in most cases. However, persistent irAEs and death were reported, mainly in patients treated with ipilimumab.
LIMITATIONS
Our study is limited by information available in the original reports.
CONCLUSIONS
Evidence from case reports shows that cancer patients develop irAEs following checkpoint blockade therapy, and can occasionally develop clearly defined autoimmune systemic diseases. While discontinuation of therapy and/or treatment can result in resolution of irAEs, long-term sequelae and death have been reported.

Review
IMPORTANCE
Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are related inflammatory disorders occurring in persons aged 50 years and older. Diagnostic and therapeutic approaches are heterogeneous in clinical practice.
OBJECTIVE
To summarize current evidence regarding optimal methods for diagnosing and treating PMR and GCA.
EVIDENCE REVIEW
MEDLINE, EMBASE, and Cochrane databases were searched from their inception dates to March 30, 2016. Screening by 2 authors resulted in 6626 abstracts, of which 50 articles met the inclusion criteria. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool or American College of Cardiology Foundation/American Heart Association methodology.
FINDINGS
Twenty randomized clinical trials for therapy (n = 1016 participants) and 30 imaging studies for diagnosis and/or assessing response to therapy (n = 2080 participants) were included. The diagnosis of PMR is based on clinical features such as new-onset bilateral shoulder pain, including subdeltoid bursitis, muscle or joint stiffness, and functional impairment. Headache and visual disturbances including loss of vision are characteristic of GCA. Constitutional symptoms and elevated inflammatory markers (>90%) are common in both diseases. Ultrasound imaging enables detection of bilateral subdeltoid bursitis in 69% of PMR patients. In GCA, temporal artery biopsy remains the standard for definitive diagnosis. Ultrasound and magnetic resonance imaging (MRI) of large vessels revealing inflammation-induced wall thickening support the diagnosis of GCA (specificity 78%-100% for ultrasound and 73%-97% for MRI). Glucocorticoids remain the primary treatment, but the optimal initial dose and tapering treatment regimens are unknown. According to consensus-based recommendations, initial therapy for PMR is prednisone, 12.5 to 25 mg/day or equivalent, and 40 to 60 mg/day for GCA, followed by individualized tapering regimens in both diseases. Adjunctive methotrexate may reduce cumulative glucocorticoid dosage by 20% to 44% and relapses by 36% to 54% in both PMR and GCA. Use of tocilizumab as additional treatment with prednisone showed a 2- to 4-fold increase in remission rates of GCA in a randomized clinical trial (N = 30).
CONCLUSIONS AND RELEVANCE
Diagnosis of PMR/GCA is made by clinical features and elevated inflammatory markers. In PMR, ultrasound imaging may improve diagnostic accuracy. In GCA, temporal artery biopsy may not be required in patients with typical disease features accompanied by characteristic ultrasound or MRI findings. Consensus-based recommendations suggest glucocorticoids as the most effective therapy for PMR/GCA. Methotrexate may be added to glucocorticoids in patients at risk for relapse and in those with glucocorticoid-related adverse effects or need for prolonged glucocorticoid therapy.

Review
Patient-reported outcomes (PROs) are being increasingly recognized as important measures by rheumatologists. The objective of this review was to evaluate the frequency of use of PROs in studies of patients with polymyalgia rheumatica (PMR). A systematic literature search was performed in PubMed (up to April 2015) to identify any type of clinical studies reporting any type of PROs in patients with PMR. Articles were excluded if they did not include adults with PMR or did not report any PROs. Characteristics of each study such as study design, follow-up, treatment assessed if any, number of patients, mean age, gender, and a description of PROs used were collected to perform a descriptive analysis. From 118 initial studies captured, 28 articles met the predefined criteria, and 20 were finally included in this review. Ten studies (50 %) were randomized clinical trials (RCTs), and 8 (40 %) were cohorts. The most frequently reported domains were: pain (90 %), being the most frequent tool using a visual analogue scale; morning stiffness in minutes (85 %); and function (25 %), evaluated through the Health Assessment Questionnaire. Other domains such as patient global assessment, fatigue, quality of life, and anxiety and depression were infrequently reported. A larger proportion of PROs were included in cohorts in comparison with RCT. Pain and morning stiffness are the most frequently reported PROs. Other domains that may appear relevant for patients are infrequently reported, especially function.

The Journal of Rheumatology Dec 2015To identify the instruments used to assess polymyalgia rheumatica (PMR) in published studies. (Review)
Review
OBJECTIVE
To identify the instruments used to assess polymyalgia rheumatica (PMR) in published studies.
METHODS
A systematic literature review of clinical trials and longitudinal observational studies related to PMR, published from 1970 to 2014, was carried out. All outcome and assessment instruments were extracted and categorized according to core areas and domains, as defined by the OMERACT (Outcome Measures in Rheumatology) Filter 2.0.
RESULTS
Thirty-five articles (3221 patients) were included: 12 randomized controlled trials (RCT); 3 nonrandomized trials; and 20 observational studies. More than 20 domains were identified, measured by 29 different instruments. The most frequently used measures were pain, morning stiffness, patient global assessment and physician global assessment, erythrocyte sedimentation rate, and C-reactive protein. The definition of outcomes varied considerably between studies.
CONCLUSION
The outcome measures and instruments used in PMR are numerous and diversely defined. The establishment of a core set of validated and standardized outcome measurements is needed.

RMD Open 2015To review the evidence for accuracy of imaging for diagnosis of polymyalgia rheumatica (PMR).
OBJECTIVES
To review the evidence for accuracy of imaging for diagnosis of polymyalgia rheumatica (PMR).
METHODS
Searches included MEDLINE, EMBASE and PubMed. Evaluations of diagnostic accuracy of imaging tests for PMR were eligible, excluding reports with <10 PMR cases. Two authors independently extracted study data and three authors assessed methodological quality using modified QUADAS-2 criteria.
RESULTS
26 studies of 2370 patients were evaluated: 10 ultrasound scanning studies; 6 MRI studies; 1 USS and MRI study; 7 18-fluorodeoxyglucose-positron emission tomography (PET) studies; 1 plain radiography and 1 technetium scintigraphy study. In four ultrasound studies, subacromial-subdeltoid bursitis had sensitivity 80% (95% CI 55% to 93%) and specificity 68% (95% CI 60% to 75%), whereas bilateral subacromial-subdeltoid bursitis had sensitivity 66% (95% CI 43% to 87%) and specificity 89% (95% CI 66% to 97%). Sensitivity for ultrasound detection of trochanteric bursitis ranged from 21% to 100%. In four ultrasound studies reporting both subacromial-subdeltoid bursitis and glenohumeral synovitis, detection of subacromial-subdeltoid bursitis was more accurate than that of glenohumeral synovitis (p=0.004). MRI and PET/CT revealed additional areas of inflammation in the spine and pelvis, including focal areas between the vertebrae and anterior to the hip joint, but the number of controls with inflammatory disease was inadequate for precise specificity estimates.
CONCLUSIONS
Subacromial-subdeltoid bursitis appears to be the most helpful ultrasound feature for PMR diagnosis, but interpretation is limited by study heterogeneity and methodological issues, including variability in blinding and potential bias due to case-control study designs. Recent MRI and PET/CT case-control studies, with blinded readers, yielded promising data requiring validation within a diagnostic cohort study.

Review
Current evidence for therapeutic interventions and prognostic factors in polymyalgia rheumatica: a systematic literature review informing the 2015 European League Against Rheumatism/American College of Rheumatology recommendations for the management of polymyalgia rheumatica.
To summarise evidence on therapeutic interventions and prognostic factors in polymyalgia rheumatica (PMR). A systematic literature review was conducted using Ovid Medline, Embase, PubMed, CINAHL, Web of Science and the Cochrane Library (1970 through April 2014). Quality of evidence (QoE) of identified studies was appraised by Grading of Recommendations Assessment, Development and Evaluation (GRADE) (interventions) and the Quality In Prognosis Studies (QUIPS) methodologies (prognostic factors). Out of 10 931 titles identified, 52 articles were finally selected. A single study indicated that an initial prednisone dose of 20 mg/day is associated with a lower short-term relapse rate than 10 mg/day but at the cost of a higher rate of adverse events. Another study suggested a comparable efficacy of intramuscular methylprednisolone and oral glucocorticoids (GCs) with lower cumulative GC doses and less weight gain in the former group. Moderate to high QoE (1-2 studies) indicated a benefit of methotrexate in remission rates and cumulative GC doses in early PMR. Anti-tumour necrosis factor α agents are ineffective for PMR treatment. Among prognostic factors, female sex, high erythrocyte sedimentation rate (ESR) and peripheral arthritis were associated in some studies with a higher relapse risk. Women and patients with high ESR also appeared to have a longer duration of treatment. Several studies of varying quality, however, failed to prove these associations. In PMR, evidence for initial GC doses and subsequent tapering regimens is limited. Intramuscular methylprednisolone and methotrexate may be effective GC sparing agents. Female sex, high ESR and peripheral arthritis at disease outset are potential risk factors for a worse prognosis.

Meta-Analysis Review
BACKGROUND
Gait analysis is increasingly being used to characterise dysfunction of the lower limb and foot in people with inflammatory arthritis (IA). The aim of the systematic review was to evaluate the spatiotemporal, foot and ankle kinematic, kinetic, peak plantar pressure and muscle activity parameters between patients with inflammatory arthritis and healthy controls.
METHODS
An electronic literature search was performed on Medline, CINAHL, SportsDiscus and The Cochrane Library. Methodological quality was assessed using a modified Quality Index. Effect sizes with 95% confidence intervals (CI) were calculated as the standardised mean difference (SMD). Meta-analysis was conducted if studies were homogenous.
RESULTS
Thirty six studies with quality ranging from high to low met the inclusion criteria. The majority of studies reported gait parameters in Rheumatoid arthritis (RA). The gait pattern in RA was characterised by decreased walking speed (SMD 95% CI -1.57, -2.25 to -0.89), decreased cadence (SMD -0.97, -1.49 to -0.45), decreased stride length (SMD -1.66, -1.84 to -1.49), decreased ankle power (SMD -1.36, -1.70 to -1.02), increased double limb support time (SMD 1.03, 0.84 to 1.22), and peak plantar pressures at the forefoot (SMD 1.11, 0.76 to 1.45). Walking velocity was reduced in psoriatic arthritis and gout with no differences in ankylosing spondylitis. No studies have been conducted in polymyalgia rheumatica, systemic sclerosis or systemic lupus erythematosus.
CONCLUSIONS
The review identified the majority of studies reporting gait adaptations in RA, but limited evidence relating to other IA conditions. Poor data reporting, small sample sizes and heterogeneity across IA conditions limit the interpretation of the findings. Future studies may consider a standardised analytical approach to gait analysis that will provide clinicians and researchers with objective evidence of foot function in people with IA.
