OBJECTIVES
To investigate the proportion and distribution of contrast enhancement (CE) of musculoskeletal structures with MRI of the thorax/abdomen/pelvis in giant cell arteritis (GCA).
METHODS
CE at 34 musculoskeletal sites was rated with a 4-point ordinal scale. Patients were divided into groups with/without glucocorticoid (GC) treatment and with/without symptoms of polymyalgia rheumatica (PMR). Two composite scores were created: an MRI-score, including seven sites and a Limited-MRI-score, including four sites.
RESULTS
Retrospectively, 90 consecutive patients with GCA were included. The population included 54 and 36 patients with and without PMR symptoms, respectively, and 45 (50%) patients were receiving GCs at the time of MRI. CE was found in 90.7% of lumbar spines, 87.5% of the pelvis, 82.2% of shoulder girdles and in 95.6% at any site in patients without GCs. The proportion of patients without and with GCs with at least moderate enhancement was 91.1%/75.6% at ≥ 1-3, 75.6%/51.1% at ≥ 4-6 and 64.4%/28.9% at ≥ 7-9 sites. The mean difference between the proportion of pathological CE in patients with and without GCs was 27.4% for synovial sites and 18.3% for periarticular/musculotendinous sites. Both composite scores captured substantial differences between groups, correlation was very strong between scores.
CONCLUSIONS
MRI shows CE of musculoskeletal structures typical of PMR in most patients with GCA, supporting the concept of "GCA-PMR Spectrum Disease". Changes are more frequent at periarticular/musculotendinous sites and in the presence of PMR symptoms. A clear response to GCs is evident, less so for periarticular/musculotendinous sites.

A 68-year-old female with a past medical history significant for tophaceous gout presented with pain and stiffness in her bilateral shoulders and hip joints for about two weeks after testing positive for COVID-19. Her laboratory results showed an elevated erythrocyte sedimentation rate (ESR) of 74 mm/h and C-reactive protein (CRP) of 25 mg/L. She showed clinical improvement in her symptoms after steroid therapy and was diagnosed with polymyalgia rheumatica (PMR). Despite prompt treatment with steroids, she continued to have persistent joint pain. Also, she developed new bilateral temporal artery tenderness, headaches, blurry vision, and jaw claudication concerning giant cell arteritis (GCA). She was admitted to the hospital for high-dose pulsed IV methylprednisolone and discharged with a steroid taper along with tocilizumab injections. Her symptoms improved rapidly, and she continued to follow up with rheumatology while continuing low-maintenance doses of prednisone. Although the association between PMR and GCA is well-known, the time it takes to reach disease remission, the rate of relapse, and the length of steroid treatment are variable. There are a few COVID-19-associated cases of PMR and GCA; however, the timeline and pathophysiology of this association remain an area for further investigation.

OBJECTIVES
To assess the accuracy of self-reported giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) diagnoses in a large French population-based prospective cohort, and to devise algorithms to improve their accuracy.
METHODS
The E3N-EPIC cohort study (Etude Epidémiologique auprès des femmes de la Mutuelle Générale de l'Education Nationale) includes 98,995 French women born between 1925 and 1950, recruited in 1990 to study risk factors of cancer and chronic diseases. They completed biennially mailed questionnaires to update their health-related information and lifestyle characteristics. In three questionnaires, women could self-report a diagnosis of GCA/PMR. Those women were additionally sent a specific questionnaire, designed to ascertain self-reported diagnoses of GCA/PMR. Four algorithms were then devised to improve their identification. Accuracies of self-reported diagnoses and of each algorithm were calculated by comparing the diagnoses with a blinded medical chart review.
RESULTS
Among 98,995 participants, 1,392 women self-reported GCA/PMR. 830 women sent back the specific questionnaire, and 202 women provided medical charts. After independent review of the 202 medical charts, 87.6 % of the self-reported diagnoses of GCA/PMR were accurate. Using additional data from a specific questionnaire (diagnosis confirmation by a physician, and self-report of >3-month of glucocorticoids), and from a reimbursement database (at least two deliveries of glucocorticoids in less than 3 consecutive months) improved their accuracy (91.8 % to 92.8 %).
CONCLUSION
The accuracy of self-reported diagnosis of GCA/PMR was high in the E3N-cohort but using additional data as a specific GCA/PMR questionnaire and/or corticosteroid reimbursement database further improved this accuracy. With nearly 600 detected cases of GCA/PMR, we will be able to investigate risk factors for GCA/PMR in women.

The combination therapy of atezolizumab, an anti-programmed cell death ligand-1 antibody, plus bevacizumab (Atz/Bev) is widely used to treat patients with advanced hepatocellular carcinoma (HCC). The development of polymyalgia rheumatica (PMR) during immune checkpoint inhibitor therapy for patients with HCC has not been reported to date. Two patients who developed PMR during Atz/Bev therapy for advanced HCC are reported. Both patients developed fever, bilateral symmetrical shoulder pain, morning stiffness, and an elevated C-reactive protein level. Their symptoms improved rapidly with prednisolone (PSL) 15-20 mg/d, and their C-reactive protein levels decreased. In PMR, long-term low-dose PSL should be administered. In the present patients who developed PMR as immune-related adverse events, starting with a small dose of PSL resulted in rapid improvement of symptoms.

RMD Open Feb 2024To determine whether antecedent sinusitis is associated with incident rheumatic disease.
OBJECTIVES
To determine whether antecedent sinusitis is associated with incident rheumatic disease.
METHODS
This population-based case-control study included all individuals meeting classification criteria for rheumatic diseases between 1995 and 2014. We matched three controls to each case on age, sex and length of prior electronic health record history. The primary exposure was presence of sinusitis, ascertained by diagnosis codes (positive predictive value 96%). We fit logistic regression models to estimate ORs for incident rheumatic diseases and disease groups, adjusted for confounders.
RESULTS
We identified 1729 incident rheumatic disease cases and 5187 matched controls (mean age 63, 67% women, median 14 years electronic health record history). After adjustment, preceding sinusitis was associated with increased risk of several rheumatic diseases, including antiphospholipid syndrome (OR 7.0, 95% CI 1.8 to 27), Sjögren's disease (OR 2.4, 95% CI 1.1 to 5.3), vasculitis (OR 1.4, 95% CI 1.1 to 1.9) and polymyalgia rheumatica (OR 1.4, 95% CI 1.0 to 2.0). Acute sinusitis was also associated with increased risk of seronegative rheumatoid arthritis (OR 1.8, 95% CI 1.1 to 3.1). Sinusitis was most associated with any rheumatic disease in the 5-10 years before disease onset (OR 1.7, 95% CI 1.3 to 2.3). Individuals with seven or more codes for sinusitis had the highest risk for rheumatic disease (OR 1.7, 95% CI 1.3 to 2.4). In addition, the association between sinusitis and incident rheumatic diseases showed the highest point estimates for never smokers (OR 1.7, 95% CI 1.3 to 2.2).
CONCLUSIONS
Preceding sinusitis is associated with increased incidence of rheumatic diseases, suggesting a possible role for sinus inflammation in their pathogenesis.

Diagnostic value of 18F-fluorodeoxyglucose positron emission tomography and computed tomography for differentiating polymyalgia rheumatica and rheumatoid arthritis: Using classification and regression tree analysis.
OBJECTIVES
Determining which sites were important to differentiate polymyalgia rheumatica (PMR) from rheumatoid arthritis (RA) using 18F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET-CT) is challenging.
METHODS
Patients with PMR or RA who were undergoing PET-CT were recruited at two mutual-aid hospitals in Japan between 2009 and 2018. Classification and regression tree (CART) analyses were performed to identify FDG uptake patterns that differentiated PMR from RA.
RESULTS
We enrolled 35 patients with PMR and 46 patients with RA. Univariate CART analysis showed that FDG uptake in the shoulder joints, spinous processes of the lumbar vertebrae, pubic symphysis, sternoclavicular joints, ischial tuberosities, greater trochanters, and hip joints differentiated PMR from RA. Multivariate CART analysis revealed that FDG uptake by at least one of the ischial tuberosities had the highest diagnostic value for distinguishing PMR from RA (sensitivity, 77.1%; specificity, 82.6%). We performed the same CART analysis to patients who had not undergone treatment (PMR, n = 28; RA, n = 9). Similar results were obtained, and sensitivity and specificity were increased (sensitivity, 89.3%; specificity, 88.8%).
CONCLUSIONS
In PET-CT, FDG uptake by at least one of the ischial tuberosities best discriminates between PMR and RA.

Review
Rheumatologists are increasingly utilizing ultrasound for suspected giant cell arteritis (GCA) or Takayasu arteritis (TAK). This enables direct confirmation of a suspected diagnosis within the examination room without further referrals. Rheumatologists can ask additional questions and explain findings to their patients while performing ultrasound, preferably in fast-track clinics to prevent vision loss. Vascular ultrasound for suspected vasculitis was recently integrated into rheumatology training in Germany. New European Alliance of Associations for Rheumatology recommendations prioritize ultrasound as the first imaging tool for suspected GCA and recommend it as an imaging option for suspected TAK alongside magnetic resonance imaging, positron emission tomography and computed tomography. Ultrasound is integral to the new classification criteria for GCA and TAK. Diagnosis is based on consistent clinical and ultrasound findings. Inconclusive cases require histology or additional imaging tests. Robust evidence establishes high sensitivities and specificities for ultrasound. Reliability is good among experts. Ultrasound reveals a characteristic non-compressible 'halo sign' indicating intima-media thickening (IMT) and, in acute disease, artery wall oedema. Ultrasound can further identify stenoses, occlusions and aneurysms, and IMT can be measured. In suspected GCA, ultrasound should include at least the temporal and axillary arteries bilaterally. Nearly all other arteries are accessible except the descending thoracic aorta. TAK mostly involves the common carotid and subclavian arteries. Ultrasound detects subclinical GCA in over 20% of polymyalgia rheumatica (PMR) patients without GCA symptoms. Patients with silent GCA should be treated as GCA because they experience more relapses and require higher glucocorticoid doses than PMR patients without GCA. Scores based on intima-thickness (IMT) of temporal and axillary arteries aid follow-up of GCA, particularly in trials. The IMT decreases more rapidly in temporal than in axillary arteries. Ascending aorta ultrasound helps monitor patients with extracranial GCA for the development of aneurysms. Experienced sonologists can easily identify pitfalls, which will be addressed in this article.

Joint Bone Spine Apr 2024To develop recommendations for the routine management of patients with polymyalgia rheumatica (PMR).
OBJECTIVE
To develop recommendations for the routine management of patients with polymyalgia rheumatica (PMR).
METHODS
Following standard procedures, a systematic review of the literature by five supervised junior rheumatologists, based on the questions selected by the steering committee (5 senior rheumatologists), was used as the basis for working meetings, followed by a one-day plenary meeting with the working group (15 members), leading to the development of the wording and determination of the strength of the recommendations and the level of agreement of the experts.
RESULTS
Five general principles and 19 recommendations were drawn up. Three recommendations relate to diagnosis and the use of imaging, and five to the assessment of the disease, its activity and comorbidities. Non-pharmacological therapies are the subject of one recommendation. Three recommendations concern initial treatment based on general corticosteroid therapy, five concern the reduction of corticosteroid therapy and follow-up, and two concern corticosteroid dependence and steroid-sparing treatments (anti-IL-6).
CONCLUSION
These recommendations take account of current data on PMR, with the aim of reducing exposure to corticosteroid therapy and its side effects in a fragile population. They are intended to be practical, to help practitioners in the day-to-day management of patients with PMR.

Giant cell arteritis (GCA) is a chronic vasculitis of large- and medium-sized vessels. The most frequent symptoms are temporal headaches, scalp tenderness, jaw claudication and polymyalgia rheumatica in 35% of patients. Atypical presentation with dry cough is very rare and could be isolated making the diagnosis difficult. Initial imaging including PET-CT could be helpful. Literature review yielded 13 case reports with available data and one case series which focused on cough and which were all be included in this study. Most of the cases included males (n = 8), with mostly isolated cough or associated to fever and weight loss. Angio-CT of aortic wall was mostly normal, whereas FDG PET-CT showed in all available cases abnormal arterial thoracic uptake. Temporal artery biopsy was almost suggestive of GCA in all available cases. Cough was steroid responsive usually within few days in all cases without any need of combined therapy. Giant cell arteritis is the most common large-vessel vasculitis over the age of 50 in western countries. Isolated dry cough is extremely rare and encountered in less than 5% of cases.

Zeitschrift Fur Rheumatologie Feb 2024This study aimed to update the prevalence estimates of inflammatory rheumatic diseases (IRD) in Germany.
OBJECTIVE
This study aimed to update the prevalence estimates of inflammatory rheumatic diseases (IRD) in Germany.
METHODS
A systematic literature search in PubMed and Web of Science (last search 08 November 2022) identified original articles (regional and nationwide surveys and claims data analyses for arthritides, connective tissue diseases, and vasculitides) on prevalences for the period 2014-2022. Data sources, collection period, case definition, and risk of bias are reported. Prevalences were estimated from available national data, with consideration of international data.
RESULTS
Screening by two authors yielded 263 hits, of which 18 claims data analyses and 2 surveys met the inclusion criteria. Prevalences ranged from 0.42 to 1.85% (rheumatoid arthritis), 0.32-0.5% (ankylosing spondylitis), 0.11-0.32% (psoriatic arthritis), 0.037-0.14% (systemic lupus erythematosus), 0.07-0.77% (Sjögren's disease/sicca syndrome), 0.14-0.15% (polymyalgia rheumatica, ≥ 40 years), 0.04-0.05% (giant cell arteritis, ≥ 50 years), and 0.015-0.026% (ANCA-associated vasculitis). The risk of bias was moderate in 13 and high in 7 studies. Based on the results, we estimate the prevalence of IRD in Germany to be 2.2-3.0%, which corresponds to approximately 1.5-2.1 million affected individuals. The prevalence of juvenile idiopathic arthritis was reported to be around 0.10% (0.07-0.10%) of 0-18-year-olds, corresponding to about 14,000 children and adolescents in Germany.
CONCLUSION
This systematic review shows an increase in the prevalence of IRD in Germany, which is almost exclusively based on claims data analyses. In the absence of multistage population studies, the available data are, overall, uncertain sources for prevalence estimates, with a moderate to high risk of bias.
