Did the first description of patients with polymyalgia rheumatica take place in Scotland or in Denmark?

The first description of polymyalgia rheumatica (PMR) is generally attributed to Dr. Bruce. In an 1888 article entitled Senile rheumatic gout, he described five male patients aged from 60 to 74 years whom he had visited at the Strathpeffer spa in Scotland. In 1945, Dr. Holst and Dr. Johansen reported on five female patients examined over several months at the Medical Department of Roskilde County Hospital in Denmark. These patients suffered from hip, upper arms, and neck pain associated with elevated ESR and constitutional manifestations such as low-grade fever or loss of weight. In the same year, Meulengracht, another Danish physician, reported on two patients with shoulder pain and stiffness associated with fever, weight loss, and an increased erythrocyte sedimentation rate. As in the five patients reported by Dr. Holst and Dr. Johansen, a prolonged recovery time was recorded. On reading and comparing these three accounts, we question whether it is correct to attribute the first description of PMR to Dr. Bruce and put forward shifting this accolade to the three Danish physicians.

Anti-interleukin-6 receptor antibody for the treatment of remitting seronegative symmetrical synovitis with pitting oedema: a new outlook?

We present the case of an elderly man with a small-joint polyarthritis, accompanied by pitting oedema, involving hands and feet, raising clinical suspicion of remitting seronegative symmetrical synovitis with pitting oedema (RS3PE). Treatment with corticosteroids was initiated with significant improvement, but unacceptable iatrogeny ensued, and tapering was not possible without disease flare-up. A trial of tocilizumab allowed disease activity control, slow weaning of corticosteroids and, ultimately, its suspension. RS3PE is a rare rheumatological entity, initially thought to be a variant of rheumatoid arthritis (RA), with shared traits with polymyalgia rheumatica (PMR), and other seronegative spondyloarthropathies, thereby implying a shared pathophysiological background. Elevated levels of interleukin 6 (IL-6) are found in patients with RA, have shown to mirror disease activity in PMR and have also been described in the serum and synovial fluid of patients with RS3PE. Tocilizumab, an anti-IL-6 receptor antibody, shows auspicious results in several other rare rheumatic diseases other than RA.

Concomitant Polymyalgia Rheumatica and Giant Cell Arteritis Associated with Cystic Echinococcosis: A Rare Geriatric Case

INTRODUCTION

Parasitic infections could be an important triggering factor for autoimmune diseases. We present a clinical case of concomitant polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) induced with cystic echinococcosis (CE).

CASE PRESENTATION

A 74-year-old male was admitted with a 2-month history of progressive pain at the shoulders and hip, movement restriction, and constitutional symptoms. As a result of the examinations performed due to rheumatological complaints, PMR and GCA were diagnosed. The cystic appearance, which was incidentally detected in the liver 6 months ago and not examined at that time, was found to be hydatid cyst. Medical treatment was initiated for all three conditions and the patient's symptoms improved significantly.

DISCUSSION

Parasite infections may cause various autoimmune diseases because of molecular mimicry or sustained immune activation. Echinococcus granulosus is a very complex multicellular parasite and highly immunogenic for humans. Some body parts of the parasite, the outer surface and secreted particles, stimulate the host immune system strongly.

CONCLUSION

The first case in the literature of coexistence of PMR and GCA associated with CE. Autoimmune diseases should be evaluated in patients with CE. Furthermore, CE should be considered in patients with autoimmune diseases in the presence of a cyst.

Review of phase 2/3 trials in polymyalgia rheumatica and giant cell arteritis

INTRODUCTION

GCA (giant cell arteritis) and PMR (polymyalgia rheumatica) are two overlapping inflammatory rheumatic conditions that are seen exclusively in older adults, sharing some common features. GCA is a clinical syndrome characterized by inflammation of the medium and large arteries, with both cranial and extracranial symptoms. PMR is a clinical syndrome characterized by stiffness in the neck, shoulder, and pelvic girdle muscles. Both are associated with constitutional symptoms.

AREAS COVERED

In this review, we assess the established and upcoming treatments for GCA and PMR. We review the current treatment landscape, completed trials, and upcoming trials in these conditions, to identify new and promising therapies.

EXPERT OPINION

Early use of glucocorticoids (GC) remains integral to the immediate management of PMR and GCA but being aware of patient co-morbidities that may influence treatment toxicity is paramount. As such GC sparing agents are required in the treatment of PMR. Currently there are limited treatment options available for PMR and GCA, and significant unmet needs remain. Newer mechanisms of action, and hence therapeutic options being studied include CD4 T cell co-stimulation blockade, IL-17 inhibition, IL-12/23 inhibition, GM-CSF inhibition, IL-1β inhibition, TNF-α antagonist and Jak inhibition, among others, which will be discussed in this review.

Subclinical giant cell arteritis increases the risk of relapse in polymyalgia rheumatica

OBJECTIVE

The aim of the present study was to determine the clinical significance of subclinical giant cell arteritis (GCA) in polymyalgia rheumatica (PMR) and ascertain its optimal treatment approach.

METHODS

Patients with PMR who fulfilled the 2012 European Alliance of Associations for Rheumatology/American College of Rheumatology Provisional Classification Criteria for PMR, did not have GCA symptoms and were routinely followed up for 2 years and were stratified into two groups, according to their ultrasound results: isolated PMR and PMR with subclinical GCA. The outcomes (relapses, glucocorticoid use and disease-modifying antirheumatic drug treatments) between groups were compared.

RESULTS

We included 150 patients with PMR (50 with subclinical GCA) with a median (IQR) follow-up of 22 (20-24) months. Overall, 47 patients (31.3 %) had a relapse, 31 (62%) in the subclinical GCA group and 16 (16%) in the isolated PMR group (p<0.001). Among patients with subclinical GCA, no differences were found in the mean (SD) prednisone starting dosage between relapsed and non-relapsed patients (32.4±15.6 vs 35.5±12.1 mg, respectively, p=0.722). Patients with subclinical GCA who relapsed had a faster prednisone dose tapering in the first 3 months compared with the non-relapsed patients, with a mean dose at the third month of 10.0±5.2 versus 15.2±7.9 mg daily (p<0.001). No differences were found between relapsing and non-relapsed patients with subclinical GCA regarding age, sex, C reactive protein and erythrocyte sedimentation rate.

CONCLUSIONS

Patients with PMR and subclinical GCA had a significantly higher number of relapses during a 2-year follow-up than patients with isolated PMR. Lower starting doses and rapid glucocorticoid tapering in the first 3 months emerged as risk factors for relapse.

Senescent cells in giant cell arteritis display an inflammatory phenotype participating in tissue injury via IL-6-dependent pathways

OBJECTIVES

Age is the strongest risk factor of giant cell arteritis (GCA), implying a possible pathogenetic role of cellular senescence. To address this question, we applied an established senescence specific multimarker algorithm in temporal artery biopsies (TABs) of GCA patients.

METHODS

75(+) TABs from GCA patients, 22(-) TABs from polymyalgia rheumatica (PMR) patients and 10(-) TABs from non-GCA/non-PMR patients were retrospectively retrieved and analysed. Synovial tissue specimens from patients with inflammatory arthritis and aorta tissue were used as disease control samples. Senescent cells and their histological origin were identified with specific cellular markers; IL-6 and MMP-9 were investigated as components of the senescent associated secretory phenotype by triple costaining. GCA or PMR artery culture supernatants were applied to fibroblasts, HUVECs and monocytes with or without IL-6R blocking agent to explore the induction of IL-6-associated cellular senescence.

RESULTS

Senescent cells were present in GCA arteries at higher proportion compared with PMR (9.50% vs 2.66%, respectively, p<0.0001) and were mainly originated from fibroblasts, macrophages and endothelial cells. IL-6 was expressed by senescent fibroblasts, and macrophages while MMP-9 by senescent fibroblasts only. IL-6(+) senescent cells were associated with the extension of vascular inflammation (transmural inflammation vs adventitia limited disease: 10.02% vs 4.37%, respectively, p<0.0001). GCA but not PMR artery culture supernatant could induce IL-6-associated senescence that was partially inhibited by IL-6R blockade.

CONCLUSIONS

Senescent cells with inflammatory phenotype are present in GCA arteries and are associated with the tissue inflammatory bulk, suggesting a potential implication in disease pathogenesis.

Accuracy of self-reported diagnoses of polymyalgia rheumatica and giant cell arteritis in the French prospective E3N- EPIC cohort: A validation study

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.

Humoral SARS-CoV-2 Vaccine Responses in Patients With Giant Cell Arteritis and Polymyalgia Rheumatica: Decay After Primary Vaccination and Effects of the Booster

OBJECTIVE

Vaccination remains essential in preventing morbidity of SARS-CoV-2 infections. We previously showed that >10 mg/day of prednisolone and methotrexate was associated with reduced antibody concentrations after primary vaccination in patients with giant cell arteritis (GCA) and polymyalgia rheumatica (PMR). This follow-up study was undertaken to measure the decay of antibody concentrations and the immunogenicity of SARS-CoV-2 booster vaccination.

METHODS

Patients with GCA/PMR included in the primary vaccination (BNT162b2 [Pfizer-BioNTech] or ChAdOx1 [Oxford/AstraZeneca]) study were asked again to donate blood samples 6 months after primary vaccination (n = 24) and 1 month after booster vaccination (n = 46, BNT162b2 or mRNA1273). Data were compared to those of age-, sex-, and vaccine-matched controls (n = 58 and n = 42, respectively). Multiple linear regression was performed with post-booster antibody concentrations as dependent variable and post-primary vaccination antibodies, prednisolone >10mg/day, and methotrexate use as predicting variables.

RESULTS

Antibody concentrations decreased faster over time in GCA/PMR patients than in controls, which was associated with prednisolone treatment during primary vaccination. Post-booster antibody concentrations were comparable between patients and controls. Antibody concentrations post primary vaccination, but not treatment during booster vaccination, were predictive for antibody concentrations post booster vaccination.

CONCLUSION

These results indicate that the decay of humoral immunity after primary vaccination is associated with prednisolone treatment, whereas the subsequent increase after booster vaccination, was not. Patients with low antibody concentrations following primary vaccination remained at an immunogenic disadvantage after a single booster vaccination. This longitudinal study in GCA/PMR patients stresses the importance of repeated booster vaccination for patients with poor responses to primary vaccination.

Combining immune-checkpoint inhibitors with tocilizumab to treat a lung adenocarcinoma patient with pre-existing polymyalgia rheumatica: A case report

Immune-checkpoint inhibitors (ICIs) have changed the management of advanced cancers. However, patients with pre-existing autoimmune diseases (ADs) have usually been excluded from clinical trials of ICIs due to concerns about exacerbation of AD. Here, we combined ICIs with selective immunosuppressant treatment in a metastatic lung adenocarcinoma patient with active pre-existing polymyalgia rheumatica (PMR). Remarkably, the strategy led to durable response and no exacerbation of PMR. Thus, we provide the first clinical evidence of treating metastatic cancer with ICIs and concomitant use of tocilizumab and hydroxychloroquine for active pre-existing PMR.

Executive summary on the optimization of the multidisciplinary and integrated approach to polymyalgia rheumatica and giant cell arteritis in Madrid region

Polymyalgia rheumatica and giant cell arteritis can be a medical emergency in which a delay in correct diagnosis and therapeutic management can cause serious complications. With the aim of improving the care of patients with these pathologies in the Community of Madrid, a study was designed to identify the causes and possible solutions to address the problems related to the diagnosis of these pathologies. After the analysis, 11 areas of improvement related to four different aspects of the care process were identified: coordination and protocols, equipment, training and awareness of pathologies, and patient experience. Of all the areas identified, it was considered a priority to resolve those related to the generation of protocols for the comprehensive management of the pathologies, which include all the specialties and levels of care involved. Another crucial aspect is the increase in the degree of clinical suspicion of these pathologies.

Subclinical giant cell arteritis in polymyalgia rheumatica: Concurrent conditions or a common spectrum of inflammatory diseases?

Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are common conditions in older adults. Their clinical connection has been recognized over time, with many patients experiencing both conditions separately, simultaneously or in temporal sequence to each other. Early GCA detection is essential to prevent vascular damage, but identifying subclinical GCA in PMR patients remains a challenge and routine screening is not standard practice. Subclinical GCA prevalence in newly diagnosed PMR patients ranges from 23 to 29%, depending on the screening method. Vessel wall imaging and temporal artery biopsy can detect subclinical GCA. Epidemiology and trigger factors show similarities between the two conditions, but PMR is more common than GCA. Genetic and pathogenesis studies reveal shared inflammatory mechanisms involving dendritic cells, pro-inflammatory macrophages, and an IL-6 signature. However, the inflammatory infiltrates differ, with extensive T cell infiltrates seen in GCA while PMR shows an incomplete profile of T cell and macrophage-derived cytokines. Glucocorticoid treatment is effective for both conditions, but the steroid requirements vary. PMR overall mortality might be similar to the general population, while GCA patients with aortic inflammatory aneurysms face increased mortality risk. The GCA-PMR association warrants further research. Considering their kinship, recently the term GCA-PMR Spectrum Disease (GPSD) has been proposed.

Ultrasound description and follow up of painful cervical interspinous bursitis in a Polymyalgia Rheumatica patient - a case report

We present a Polymyalgia Rheumatica (PMR) case with active Cervical Interspinous Bursitis (CIB) causing debilitat-ing neck pain as the most intensive symptom of the disease as reported by the patient. CIB was diagnosed and followed by Musculoskeletal Ultrasound (MSUS). MSUS examination of patient's posterior cervical region reviled well demarcated an-/ hypoechoic lesions around and cranially of the spinous processes of the sixth and seventh cervical vertebra. The initial detailed sonographic characteristics of the CIB are described, as well as the evolution of lesions size and extent with the treatment and patient's clinical improvement. To our knowledge this is the rst detailed sonographic description of CIB in PMR.

Association between infection and the onset of giant cell arteritis and polymyalgia rheumatica: a systematic review and 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 Herpes Zoster (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.

Clinical, laboratory and ultrasonographic findings at baseline predict long-term outcome of polymyalgia rheumatica: a multicentric retrospective study : Polymyalgia rheumatica predicted by ultrasonographic findings polymyalgia rheumatica outcome predicted early by ultrasound

To assess the rate of PMR who, during the follow-up, undergo a diagnostic shift as well as to assess which clinical, laboratory and US findings are associated to a diagnostic shift and predict the long-term evolution of PMR. All PMR followed-up for at least 12 months were included. According to the US procedures performed at diagnosis, patients were subdivided into four subgroups. Clinical data from follow-up visits at 12, 24, 48 and 60 months, including a diagnostic shift, the number of relapses and immunosuppressive and steroid treatment, were recorded. A total of 201 patients were included. During the follow-up, up to 60% had a change in diagnosis. Bilateral LHBT was associated with persistence in PMR diagnosis, whereas GH synovitis and RF positivity to a diagnostic shift. Patients undergoing diagnostic shift had a higher frequency of GH synovitis, shoulder PD, higher CRP, WBC, PLT and Hb and longer time to achieve remission, while those maintaining diagnosis had bilateral exudative LHBT and SA-SD bursitis, higher ESR, lower Hb and shorter time to remission. Cluster analysis identified a subgroup of older patients, with lower CRP, WBC, PLT and Hb, lower PD signal or peripheral synovitis who had a higher persistence in PMR diagnosis, suffered from more flares and took more GCs. Most PMR have their diagnosis changed during follow-up. The early use of the US is associated with a lower dosage of GCs. Patients with a definite subset of clinical, laboratory and US findings seem to be more prone to maintain the diagnosis of PMR.

Immune complex-mediated neutrophil activation in patients with polymyalgia rheumatica

OBJECTIVE

Neutrophils are important in host defence. However, neutrophils are also linked to inflammation and organ damage. The purpose of this study was to assess whether markers of neutrophil activation are increased in PMR.

METHODS

Levels of immune complexes (IC), calprotectin and neutrophil extracellular traps (NETs) were measured in plasma of healthy individuals (n = 30) and patients with PMR (n = 60), at flare and upon treatment with glucocorticoids using ELISA. Plasma-mediated neutrophil activation was assessed in presence of an FcγRIIA inhibitory antibody (IV.3).

RESULTS

Plasma levels of calprotectin and NETs were elevated in PMR (P < 0.001). Mechanistically, neutrophil activation was driven by ICs, present in plasma, able to up-regulate neutrophil activation markers CD66b and CD11b (P < 0.0001) in an FcγRIIA-dependent manner (P < 0.01). Of note, circulating levels of IC correlated with plasma induced CD66b and CD11b (r = 0.51, P = 0.004, and r = 0.46, P = 0.01, respectively) and decreased after glucocorticoid therapy. In contrast to NETs, calprotectin significantly decreased after glucocorticoid therapy (P < 0.001) and was higher in PMR without overlapping GCA compared with patients with overlapping disease (P = 0.014). Interestingly, musculoskeletal involvement was associated with elevated levels of calprotectin before initiation of glucocorticoid therapy (P = 0.036).

CONCLUSIONS

Neutrophil activation, including NET formation, is increased in PMR, through IC-mediated engagement of FcγRIIA. Clinically, neutrophil activation is associated with musculoskeletal involvement, with calprotectin, but not NETs, being a biomarker of treatment response in PMR patients. In all, IC-mediated neutrophil activation is a central process in PMR pathogenesis identifying potential novel therapeutic targets (FcγRIIA), as well as soluble markers for disease monitoring (calprotectin).

The incidence and characteristics of giant cell arteritis in Hispanics and the associated outcomes of ischemic ocular events and stroke

Giant cell arteritis (GCA) is a large vessel vasculitis whereby up to half of all patients show ocular involvement, highlighting the importance of treating GCA before it leads to irreversible blindness. Most of the research published for GCA and associated adverse ocular events are based on majority Caucasian populations establishing the current belief that Hispanics have a much lower incident of GCA. We sought to investigate the incidence of GCA in Hispanics and characterize associated ocular events, stroke rates, and comorbid diseases. We conducted a retrospective cohort study of GCA-coded medical records in self-identified Hispanics assessed at the University Medical Center Hospital in El Paso, Texas. From 2000 to 2019, there were 68 new cases of GCA in the Hispanics which represents an average incidence of 0.062% with a 95% confidence interval of [0.05, 0.09] of Hispanics over the age of 50 admitted to University Medical Center hospital. Of the subjects diagnosed with GCA, the majority had ocular involvement such as blurry vision (47.06%), ocular pain (26.47%), and blindness (14.71%). We did not observe a history of stroke had a statistically significant difference associated with GCA with ophthalmic disease compared to GCA without ophthalmic disease. Polymyalgia rheumatica (PMR) was identified in only 2.94% of the Hispanic subjects with GCA. Major conclusions in our study advocate Hispanics with GCA are prevalent and unique in its associations with other comorbid diseases. Unlike non-Hispanic White populations, Hispanic subjects with GCA do not show an association with PMR nor an increased association with stroke.

A case of giant cell arteritis complicated by polymyalgia rheumatica with scalp necrosis and refractory jaw claudication

Scalp necrosis is a rare complication of giant cell arteritis (GCA); however, it is a predictor of severe disease. In this case study, a patient presented with GCA complicated by polymyalgia rheumatica with scalp necrosis. An 86-year-old woman was admitted to the hospital for pulsating headache, scalp pain, jaw claudication, and generalised pain. Bilateral temporal arteries were found to be distended and pulseless, and scalp necrosis was observed in the parietal region. Simultaneous high-resolution contrast-enhanced magnetic resonance imaging (MRI) sequences of the head, shoulder, and hip showed staining around the bilateral shallow temporal arteries, shoulder, and hip joints, which was confirmed as GCA with polymyalgia rheumatica using other examination findings. After treatment with early induction remission therapy, scalp necrosis healed, but jaw claudication persisted. Six months after the start of treatment, scalp necrosis was cured to full hair growth. Despite remission induction therapy combined with tocilizumab, the patient had persistent jaw claudication for several months. At that time, a high-resolution contrast-enhanced MRI re-examination was useful in assessing disease activity. GCA with scalp necrosis may cause prolonged jaw claudication reflecting the progression of ischaemic lesions, whereas the disease activity can be accurately assessed by combining MRI studies.

[A case of giant cell arteritis after prednisolone dose reduction during treatment of polymyalgia rheumatica]

Giant cell arteritis (GCA) is closely associated with polymyalgia rheumatica (PMR). We herein report an 82-year-old woman who developed GCA during PMR treatment. She initially presented with shoulder pain and was diagnosed with PMR based on elevated serum C-reactive protein (CRP) levels and bursitis detected in both shoulders on ultrasonography (US). Treatment was initiated with a daily dose of 15 mg prednisolone (PSL), which led to rapid symptom alleviation, and the dosage was tapered to 1 mg/day. One month later, she developed myalgia extending from the lumbar region to the thigh and tenderness in the left temporal region. However, no abnormalities in the temporal artery were observed on US. Although the PSL dose was increased to 2 mg for relapse of PMR, the symptoms did not improve. One week later, she developed occipital pain with an increased CRP level of 9 mg/dL. She was diagnosed with GCA based on the 1990 ACR Classification Criteria. Fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) detected anomalous accumulations in the bilateral superficial temporal and vertebral arteries, but not in the larger vessels. We therefore diagnosed her with cranial-type GCA. At this time point, we repeated US and found a halo sign in the temporal artery. Although epithelioid and giant cells were not observed in the temporal artery biopsy, vascular inflammatory findings such as disruption of the internal elastic lamina and chronic inflammatory cell infiltration were noted. Symptoms improved immediately and CRP levels decreased after the PSL dose was increased to 30 mg daily. To mitigate the risk of steroid-induced diabetes, tocilizumab was introduced, and gradual tapering of PSL was implemented. In conclusion, we encountered a case of GCA that developed after PSL reduction during the course of PMR. PET/CT confirmed intracranial artery inflammation and facilitated a definitive diagnosis. Although PET/CT cannot be routinely performed for diagnose in Japan, we consider it useful as an adjunctive diagnostic tool.

Polymyalgia Rheumatica

BACKGROUND

Polymyalgia rheumatica (PMR) is among the most common inflammatory rheumatic diseases in older adults. Presumed risk factors include female sex, previous infections, and genetic factors. No epidemiological data on PMR in Germany have been available until now.

METHODS

This review is based on publications retrieved by a selective literature search in PubMed. Moreover, the administrative incidence and prevalence of PMR in the years 2011-2019 was determined from data of the AOK Baden-Württemberg statutory health insurance carrier for insurees aged 40 and older. In addition, we quantified the number of consultations with physicians involved in the diagnosis.

RESULTS

The annual age- and sex-standardized incidence and prevalence of PMR from 2011 to 2019 were 18.6/100 000 persons and 138.8/100 000 persons, respectively. The incidence was higher in women than in men (21.8/100 000 vs. 12.8/100 000 persons per year). 60% of the cases were diagnosed in primary care practices. The treatment of PMR with orally administered glucocorticoids usually results in a treatment response within a few days to weeks. Approximately 43% of patients experience recurrent symptoms within a year, requiring adjustment of the glucocorticoid dose. For older patients with impaired physical ability, additional non-pharmacological treatment with exercise programs plays an important role.

CONCLUSION

PMR usually takes an uncomplicated course under treatment and can be managed in primary care, but these patients are often multimorbid and require frequent follow-up. Along with research on the etiology of the disease, further studies are needed to identify the risk factors for a chronic course and to evaluate the potential effects of non-pharmacological measures.

Glucocorticoids Are Not Associated with Bone Mineral Density in Patients with Polymyalgia Rheumatica, Giant Cell Arteritis and Other Vasculitides—Cross-Sectional Baseline Analysis of the Prospective Rh-GIOP Cohort

Background: Glucocorticoids (GCs) can cause osteoporosis (OP). Prior observational research on bone density and the effects of GCs in polymyalgia rheumatica (PMR) and vasculitides is scarce and inconclusive. Methods: Rh-GIOP is a prospective cohort study of bone health in patients with inflammatory rheumatic diseases. In this cross-sectional baseline analysis, we focused on patients with PMR and different forms of vasculitides. Multivariable linear regression was used to model the effect of current and cumulative GC intake on the minimum T-score at any site (mTs; at either lumbar spine or hip), with comprehensive adjustment for confounders. In separate models, GCs were modelled both as continuous and categorical predictors. Sensitivity analyses, stratifying by measurement site and disease, were conducted. Results: A total of 198 patients, with a mean age of 67.7 ± 11.4 years and a mean disease duration of 5.3 ± 6.3 years, were included. Most patients suffered from PMR (36%), giant cell arteritis (26%) or granulomatosis with polyangiitis (17%). Women comprised 66.7% of the patients, and 87.4% were currently taking GCs. The mean CRP was 13.2 ± 26.1 mg/L. OP diagnosed by dual energy X-ray absorptiometry (DXA) (T-score ≤ −2.5) was present in 19.7% of the patients. While 88% were taking vitamin D supplements, calcium supplementation (4%) and treatment with anti-resorptive agents (17%) were relatively infrequent. Only 7% had a vitamin D deficit. Neither current (β(continuous model) = −0.01, 97.5% CI –0.02 to 0.01; p(all models) ≥ 0.49) nor cumulative (β(continuous model) = 0.01, 97.5% CI −0.04 to 0.07; p(all models) ≥ 0.35) GC doses were associated with mTs in any model. CRP was not associated with mTs in any model (p(all models) ≥ 0.56), and no interaction between CRP and GC intake was observed (p for interaction(all models) ≥ 0.32). Across all analyses, lower body mass index (p(all models) ≤ 0.01), history of vertebral fractures (p(all models) ≤ 0.02) and proton-pump inhibitor intake (p(all models) ≤ 0.04) were associated with bone loss. Sensitivity analyses with femoral neck and lumbar spine T-scores as dependent variables led to similar results as the analysis that excluded patients with PMR. Conclusions: In this cohort of PMR and vasculitides, we found a similar prevalence of OP by DXA to the overall elderly German population. Vitamin D supplementation was very common, and vitamin D insufficiency was less frequent than expected in Germans. There was no association between current or cumulative GC intake, CRP and impaired bone density. Proton-pump inhibitors seem to be a major, but somewhat neglected, risk factor for OP and should be given more attention. Our findings require confirmation from longitudinal analyses of the Rh-GIOP and other cohorts.

Risk of Adrenal Insufficiency in Patients with Polymyalgia Rheumatica Versus Patients with Rheumatoid Arthritis: A Cross-Sectional Study

OBJECTIVE

To determine whether patients with polymyalgia rheumatica (PMR) are more susceptible to glucocorticoid-induced adrenal insufficiency, one of the barriers to glucocorticoid tapering strategies, compared to patients with rheumatoid arthritis (RA).

METHODS

This cross-sectional study included PMR and RA patients who underwent adrenocorticotropic hormone (ACTH) tests to assess adrenal function. The eligibility criteria were as follows: previous use of prednisolone (PSL) ≥ 5 mg/day, use of PSL for 6 consecutive months before ACTH test, and current use of PSL at 5 mg/day or less. The association between disease type (PMR vs. RA) and insufficient adrenal response was assessed using logistic regression models.

RESULTS

Twenty-six of 34 (76.5%) patients with PMR and 13 of 37 (35.1%) patients with RA had insufficient adrenal response. Compared to patients with RA, patients with PMR were more likely to have insufficient adrenal response, even after adjusting for age, sex, and PSL dose (adjusted odds ratio, 6.75; 95% confidence interval, 1.78-25.60).

CONCLUSION

Patients with PMR have a higher risk of glucocorticoid-induced adrenal insufficiency than patients with RA. Assessing the adrenal function in patients with PMR will contribute to establishing a more appropriate glucocorticoid reduction strategy.

Giant cell arteritis characterised by sore throat

Giant cell arteritis is a devastating condition that can lead to permanent vision loss. Early diagnosis is vital to initiate corticosteroid treatment before irreversible visual symptoms develop. This case study examines an 81-year-old woman with a history of polymyalgia rheumatica who initially presented with sore throat and headache. She was ultimately diagnosed with giant cell arteritis. However, her diagnosis was delayed by multiple emergency and outpatient providers who failed to evaluate her for giant cell arteritis. Her story reflects the importance of assessing polymyalgia rheumatica patients for giant cell arteritis even when presenting with more unusual symptoms, such as sore throat.

Fracture Risk and Its Prevention Patterns in Korean Patients with Polymyalgia Rheumatica: a Retrospective Cohort Study

BACKGROUND

To evaluate the incidence of fractures and fracture risk factors in Korean patients with polymyalgia rheumatica (PMR).

METHODS

All PMR patients who visited a rheumatology clinic at a tertiary referral hospital between March 2005 and March 2018 were retrospectively assessed. We estimated bone mineral density (BMD) screening rate within 6 months of the first visit and classified the patients according to the performance and results of BMD screening. Incidence rates (IRs) of fractures were calculated in each group and risk factors for fractures were identified using Poisson regression analysis.

RESULTS

A total of 95 PMR patients with median (interquartile range) age of 64.0 (56.0-72.0) years were included. Baseline BMD was assessed in only 55.8% of these patients (n = 53); 24 patients with osteoporosis, 20 with osteopenia, and 9 with normal BMD. During 433.1 person-years (PYs) of observation, 17 fractures occurred in 12 patients (IR, 3.93 [95% confidence interval (CI), 2.46-6.26]/100 PYs); 8.32 (95% CI, 4.09-16.90)/100 PYs in the osteopenia group, 3.40 (95% CI, 1.30-8.90)/100 PYs in the osteoporosis group, and 3.37 (95% CI, 1.53-7.39)/100 PYs in the no BMD test group. Risk factors for fractures were female sex, advanced age (≥ 65 years), longer follow-up duration, initial glucocorticoid dose ≥ 10 mg/day, and higher cumulative glucocorticoid dose over the first 6 months.

CONCLUSION

The incidence rate of fractures in Korean patients with PMR was 3.93/100 PYs. Female sex, advanced age, longer follow-up duration, and increased glucocorticoid dose are risk factors for osteoporotic fracture.

Premature atrial contractions with multiple patterns of aberrant conduction followed by torsade de pointes in a patient with polymyalgia rheumatica: A case report

RATIONALE

Recent studies have shown that QT interval prolongation is associated with disease severity and predicts mortality in systemic inflammatory diseases, particularly rheumatoid arthritis. Systemic pro-inflammatory cytokines released from synovial tissues in rheumatoid arthritis, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, could have direct effects on cardiac electrophysiology, particularly changes in the expression and function of potassium and calcium channels, resulting in QT interval prolongation on surface electrocardiogram (ECG) and an increased predisposition to develop lethal ventricular arrhythmias. However, reports on torsade de pointes (TdP) due to acquired long QT syndrome in patients with polymyalgia rheumatica (PMR) are limited.

PATIENT CONCERNS

An 85-year-old Japanese woman with active PMR developed first syncope.

DIAGNOSIS

Frequent premature atrial contractions (PACs) with multiple patterns of aberrant conduction, QT interval prolongation, and morphological T-U wave variability followed by TdP were documented. PACs were the first beat of TdP.

INTERVENTIONS

Amiodarone, together with magnesium and potassium, was intravenously administered. However, TdP resulted in a ventricular arrhythmic storm, for which sedation with mechanical ventilatory support, temporary overdrive cardiac pacing, and intravenous landiolol administration in addition to multiple direct current shocks were effective.

OUTCOMES

Approximately 2 years later, the patient was treated with amiodarone, propranolol, and prednisolone. She did not undergo implantable cardioverter-defibrillator implantation and was quite well, with no recurrence of ventricular tachyarrhythmia.

LESSONS

IL-6 hyperproduction in inflamed tissues has been widely confirmed in PMR. Frequent PACs with various patterns of aberrant conduction, QT interval prolongation, and morphological T-U wave variability followed by TdP, for which IL-6-mediated enhancement of L-type Ca2+ current and inhibition of the rapid component of the delayed rectifier K+ current are the most likely mechanisms, were documented in an elderly Japanese woman with PMR. ECG may be recorded once in patients with active PMR even when these patients do not complain of palpitation or syncope. If QT interval prolongation or arrhythmia, including even PACs, is observed, follow-up ECG may be warranted, particularly for patients with some risk factors for QT prolongation that could lead to TdP, such as advanced age, female sex, hypopotassemia, and polypharmacy.

The Spectrum of Pericardial Involvement in Giant Cell Arteritis and Polymyalgia Rheumatica: A Systematic Review of Literature

BACKGROUND

Giant cell arteritis (GCA) is a systemic vasculitis that commonly co-occurs with polymyalgia rheumatica (PMR) in elderly patients. Pericardial disease is an unusual manifestation of these inflammatory conditions, which has been reported only in case reports and small observational studies. However, no extensive research has been performed to study the demographics and clinical history of GCA or PMR patients with concomitant pericardial features. As a result, the medical evidence to help guide the physicians when evaluating such individuals is limited.

OBJECTIVE

To perform a systematic review of the medical literature in order to summarize the epidemiological and clinicopathological aspects of this unique association.

METHODS

We conducted an extensive search of PubMed, Cochrane Library, Ovid, Google Scholar, and gray literature to identify all the cases of GCA and PMR with pericardial involvement. The demographics, clinical features, and outcomes of the final cohort were reviewed and analyzed.

RESULTS

The analysis comprised 52 clinical cases (51 identified from 46 articles and 1 from the residents' clinic). These included 44 patients with GCA and 8 with PMR. The mean age at presentation was 69.5 years, with only 46% of patients older than 70 years. The most common abnormality was pericardial effusion (85%), and in 37%, the pericardial event was the initial disease manifestation. Although a significant proportion of the patients were symptomatic (69%), the classic cranial symptoms were present in only 40%. Overall, the outcome was good even in the presence of large-vessel disease, which is usually a poor prognostic factor in classic GCA. On group analysis, patients with PMR were more likely to develop cardiac tamponade (37.5%; odds ratio, 25.8; confidence interval, 2.2-297.5; p = 0.01), whereas those with GCA were more likely to have large-vessel vasculitis (43%; odds ratio, 5.18; confidence interval, 0.58-252.1; p = 0.04).

CONCLUSIONS

This study illustrates that patients with pericardial involvement represent a clinical phenotype of GCA (and possibly PMR), which is quite different from the cranial or large-vessel forms. These patients have a better prognosis likely due to younger age and presence of more overt symptoms resulting in early diagnosis.

Clinical outcomes of hospitalised patients with COVID-19 and chronic inflammatory and autoimmune rheumatic diseases: a multicentric matched cohort study

OBJECTIVES

The impact of inflammatory rheumatic diseases on COVID-19 severity is poorly known. Here, we compare the outcomes of a cohort of patients with rheumatic diseases with a matched control cohort to identify potential risk factors for severe illness.

METHODS

In this comparative cohort study, we identified hospital PCR+COVID-19 rheumatic patients with chronic inflammatory arthritis (IA) or connective tissue diseases (CTDs). Non-rheumatic controls were randomly sampled 1:1 and matched by age, sex and PCR date. The main outcome was severe COVID-19, defined as death, invasive ventilation, intensive care unit admission or serious complications. We assessed the association between the outcome and the potential prognostic variables, adjusted by COVID-19 treatment, using logistic regression.

RESULTS

The cohorts were composed of 456 rheumatic and non-rheumatic patients, in equal numbers. Mean age was 63 (IQR 53-78) years and male sex 41% in both cohorts. Rheumatic diseases were IA (60%) and CTD (40%). Most patients (74%) had been hospitalised, and the risk of severe COVID-19 was 31.6% in the rheumatic and 28.1% in the non-rheumatic cohort. Ageing, male sex and previous comorbidity (obesity, diabetes, hypertension, cardiovascular or lung disease) increased the risk in the rheumatic cohort by bivariate analysis. In logistic regression analysis, independent factors associated with severe COVID-19 were increased age (OR 4.83; 95% CI 2.78 to 8.36), male sex (1.93; CI 1.21 to 3.07) and having a CTD (OR 1.82; CI 1.00 to 3.30).

CONCLUSION

In hospitalised patients with chronic inflammatory rheumatic diseases, having a CTD but not IA nor previous immunosuppressive therapies was associated with severe COVID-19.

The association of pain and stiffness with fatigue in incident polymyalgia rheumatica: baseline results from the polymyalgia rheumatica cohort study

We aimed to examine the association between pain, stiffness and fatigue in newly diagnosed polymyalgia rheumatica (PMR) patients using baseline data from a prospective cohort study. Fatigue is a known, but often ignored symptom of PMR. Newly diagnosed PMR patients were recruited from general practice and mailed a baseline questionnaire. This included a numerical rating scale for pain and stiffness severity, manikins identifying locations of pain and stiffness and the FACIT-Fatigue questionnaire. A total of 652 PMR patients responded (88.5%). The mean age of responders was 72.6 years (SD 9.0) and the majority were female (62.0%). Manikin data demonstrated that bilateral shoulder and hip pain and stiffness were common. The mean fatigue score (FACIT) was 33.9 (SD 12.4). Adjusted regression analysis demonstrated that a higher number of pain sites (23-44 sites) and higher pain and stiffness severity were associated with greater levels of fatigue. In newly diagnosed PMR patients, fatigue was associated with PMR symptom severity.

Additional Costs of Polymyalgia Rheumatica With Giant Cell Arteritis

OBJECTIVE

To assess and compare direct costs between patients with giant cell arteritis (GCA) that is associated or not associated with polymyalgia rheumatic (PMR), and to identify the additional cost drivers due to PMR.

METHODS

A population-based, retrospective cohort study using the French National Health Insurance System Database was conducted. Cost analysis was performed from the French health insurance perspective and direct medical and nonmedical costs were taken into account (based on 2014 costs [€]). Costs were analyzed according to different components and divided into 6-month periods to assess care consumption. Longitudinal multivariate analyses, using generalized estimating equations, were used to adjust the effect of PMR on the mean cost over time.

RESULTS

Analyses were performed on 100 incident patients with GCA, 54 of whom had PMR. The cumulative additional cost due to PMR was €8,801 for 3 years, and €10,532 for 5 years. The significant additional costs occurred especially during the second and third years of follow-up, amounting to €1,769 between 12 and 18 months (P = 0.02), €1,924 between 18 and 24 months (P = 0.17), €1,458 between 24 and 30 months (P = 0.08), and €1,307 between 30 and 36 months (P = 0.07). The most important cost drivers were inpatient stays, paramedic procedures, and medications. Multivariate analyses showed a significant effect of PMR on mean cost during the first 3 years of follow-up (relative risk 1.76 [95% confidence interval 1.03-2.99], P = 0.038).

CONCLUSION

To our knowledge, this study is the first to accurately assess the cost of PMR care in patients with GCA and to highlight that PMR is largely responsible for the high cost of GCA.

[A Case of Essential Thrombocythemia with a JAK2V617F Mutation andPolymyalgia Rheumatica]

A patient with polymyalgia rheumatica(PMR)had increasing thrombocytosis. CRP levels, the ESR, and serum interleukin (IL)-6 levels were slightly elevated, and the patient tested negative for RF and anti CCP antibodies. Muscle pain was ameliorated with the administration of corticosteroids. Genetic analysis of the peripheral white blood cells demonstrated the presence of a JAK2V617F mutation. The muscle pain experienced by the patient was considered to be due to essential thrombocythemia( ET)of myeloproliferative neoplasms(MPNs)along with an inflammatory reaction. Unfortunately, the patient died suddenly because of cerebral infarction.

Polymyalgia rheumatica development in a patient under PI3K inhibitor therapy for chronic lymphocytic leukaemia

We report a patient with chronic lymphocytic leukaemia (CLL) who was treated with idelalisib, a PI3Kδ inhibitor with rituximab. After 20 weeks of treatment, the patient developed classical signs and symptoms of polymyalgia rheumatica (PMR) in association with an elevated C reactive protein of 74 mg/L. After 2 weeks of prednisolone 15 mg daily symptoms had resolved and acute phase markers normalised. To our knowledge, this is the first report of PMR developing as a complication of PI3Kδ inhibitor treatment of CLL.

Polymyalgia rheumatica and giant cell arteritis-three challenges-consequences of the vasculitis process, osteoporosis, and malignancy: A prospective cohort study protocol

INTRODUCTION

Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are common inflammatory conditions. The diagnosis of PMR/GCA poses many challenges since there are no specific diagnostic tests. Recent literature emphasizes the ability of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) to assess global disease activity in inflammatory diseases. 18F-FDG PET/CT may lead to the diagnosis at an earlier stage than conventional imaging and may also assess response to therapy. With respect to the management of PMR/GCA, there are 3 significant areas of concern as follows: vasculitis process/vascular stiffness, malignancy, and osteoporosis.

METHODS AND ANALYSIS

All patients with suspected PMR/GCR referred to the Rheumatology section of Medicine Department at Svendborg Hospital, Denmark. The 4 separate studies in the current protocol focus on: the association of clinical picture of PMR/GCA with PET findings; the validity of 18F-FDG PET/CT scan for diagnosis of PMR/GCA compared with temporal artery biopsy; the prevalence of newly diagnosed malignancies in patients with PMR/GCA, or PMR-like syndrome, with the focus on diagnostic accuracy of 18F-FDG PET/CT scan compared with conventional workup (ie, chest X-ray/abdominal ultrasound); and the impact of disease process, and also steroid treatment on bone mineral density, body composition, and vasculitis/vascular stiffness in PMR/GCA patients.

ETHICS AND DISSEMINATION

The study has been approved by the Regional Ethics Committee of the Region of Southern Denmark (identification number: S-20160098) and Danish Data Protection Agency (J.nr 16/40522). Results of the study will be disseminated via publications in peer-reviewed journals, and presentation at national and international conferences.

Polymyalgia Rheumatica and Giant Cell Arteritis: A Systematic 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.

Non-infectious aortitis: a report of 32 cases from a single tertiary centre in a 4-year period and literature review

OBJECTIVES

Non-infectious aortitis often presents with non-specific symptoms leading to inappropriate diagnostic delay. We intend to describe the clinical spectrum and outcome of patients with aortitis diagnosed at a single centre.

METHODS

We reviewed the clinical charts of patients diagnosed with non-infectious aortitis between January 2010 and December 2013 at the Rheumatology Division from a 1.000-bed tertiary teaching hospital from Northern Spain. The diagnosis of aortitis was usually based on FDG-PET-CT scan, and also occasionally on CT or MRI angiography or helical CT-scan.

RESULTS

During the period of assessment 32 patients (22 women and 10 men; mean age 68 years [range, 45-87]) were diagnosed with aortitis. The median interval from the onset of symptoms to the diagnosis was 21 months. FDG-PET CT scan was the most common tool used for the diagnosis of aortitis. The underlying conditions were the following: giant cell arteritis (n=13 cases); isolated polymyalgia rheumatica (PMR) (n=11); Sjögren's syndrome (n=2), Takayasu arteritis (n= 1); sarcoidosis (n=1), ulcerative colitis (n=1), psoriatic arthritis (n=1), and large-vessel vasculitis that also involved the aorta (n=2). The most common clinical manifestations at diagnosis were: PMR features, often with atypical clinical presentation (n=23 patients, 72%); diffuse lower limb pain (n=16 patients, 50%); constitutional symptoms (n=12 patients, 37%), inflammatory low back pain (n=9 patients, 28%) and fever (n=7 patients, 22%). Acute phase reactants were increased in most cases (median erythrocyte sedimentation rate 46 mm/1st hour, and a median serum C-reactive protein 1.5 mg/dL).

CONCLUSIONS

Aortitis is not an uncommon condition. The diagnosis is often delayed. Atypical PMR features, unexplained low back or limb pain, constitutional symptoms along with increased acute phase reactants should be considered 'red flags' to suspect the presence of aortitis.

[Thoracic endovascular aneurysm repair combined with debranching and chimney methods in a high risk patient; report of a case]

We report a case of a 77-year-old man with a thoracic aortic aneurysm, combined with chronic myelomonocytic leukemia, polymyalgia rheumatica, and atial fibrillation. Open surgery was considered as high risk because he was severely ill. Instead, partial debranching and stent graft( TEVAR) were performed by chimney method. He had no major complication after surgery, and was discharged on foot on the 15th postoperative day. In high risk cases of thoracic aortic aneurysm, TEVAR with debranching and chimney methods is effective.

Clinical practice. Giant-cell arteritis and polymyalgia rheumatica

A 79-year-old woman presents with new-onset pain in her neck and both shoulders. She takes 7.5 mg of prednisone per day for giant-cell arteritis. Occipital tenderness and diplopia developed 11 months before presentation. At that time, her erythrocyte sedimentation rate was elevated, at 78 mm per hour, and a temporal-artery biopsy revealed granulomatous arteritis. The diplopia resolved after 6 days of treatment with 60 mg of prednisone daily. Neither headache nor visual symptoms developed when the glucocorticoids were tapered. How should this patient’s care be managed?

[Polymyalgia rheumatica and aortic involvement]

Polymyalgia rheumatica (PMR) is an inflammatory disorder that affects people over 50 years of age, characterized by pain and stiffness in the neck and shoulder and pelvic girdles. PMR may occur as an isolated condition or concomitantly with giant cell arteritis. Similar to other inflammatory rheumatic disorders, PMR is associated with an increased cardiovascular risk due to inflammatory changes in large arterial vessels, which result in an increased chance of developing aneurysms and dissections. International guidelines do not provide specific indications about the management of PMR patients with aortic wall inflammation. In this review, we propose a diagnostic pathway for the management of PMR patients with aortic involvement based on literature data and personal experience.

[Peripheral arthritis in polymyalgia rheumatica]

Polymyalgia rheumatica is characterized by aching and stiffness of the shoulder, the pelvic girdles and the neck. Peripheral joint involvement is less recognized by the medical community as a sign of the disease. In this article we present two patients whose disease was manifested by peripheral symptoms. The frequency, manifestations and the pathogenesis of the disorder are discussed and the importance of recognition of these symptoms and signs of the disease is stressed.

Large-vessel involvement in giant cell arteritis and polymyalgia rheumatica

Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are closely related disorders that affect people of middle age and older, and frequently occur together. With the widespread use of newer vascular imaging modalities, large-vessel involvement (LVI) has increasingly been recognised in patients with GCA and less often in those with PMR. LVI in GCA can result in complications such as aortic aneurysm and dissection, aortic arch syndrome, and limb arteries stenosis, while vascular complications in PMR are exceedingly rare. It is still controversial which patients should be investigated for LVI, and how LVI should be diagnosed, monitored and managed. In this review, we will try to address six important issues regarding LVI in GCA and PMR.
