1 Clinical use of glucocorticoids Abi Karam Ghada

2 Pathophysiology and management of glucocorticoid induced osteoporosis. Bianchi, Genoa, Italy Biphasic Bone loss : rapid reduction of BMD during the first year (6% to 12%), followed by a slower annual loss of about 3% for as long as glucocorticoids are administered. The relative risk of fracture increases more rapidly (up to 75% within the first 3 months), and fragility fractures often occur before a significant decline in BMD become evident, (corticosteroid use does has an effect on fracture risk independently of the effects on bone density).

3 Pathophysiology: 1.Direct interaction with the bone cells: produce a decrease in osteoblastogenesis and an increase in osteoblasts apoptosis, leading to a continual decrease of synthetic ability and bone formation. Osteoclasts survival is improved by glucocorticoids. an effect on osteocytes has been also described: increased osteocyte apoptosis and decreased canalicular circulation, leading to an alteration of bone quality. 2. GH, muscle mass, sex hormones, intestinal Ca absorbtion: reduced. 3. Genetic variation in GC receptors, polymorphism in Vit D receptors.

4 Treatment of GC induced OP: 1.General measures: Ca, vit D, smoking cessation, physical activity… 2.Bisphosphonates and teriparatide: RCTs showed significant beneficial effects in preserving and/or improving the bone mineral density. Some of these agents also demonstrated to reduce the risk of vertebral fractures. The anti-fracture and long-term efficacy has not been fully clarified mainly due to the small samples studied and to the short-term follow-up of RCTs.

5 DENOSUMAB FOR PATIENTS RECEIVING LONG-TERM GLUCOCORTICOIDS WHO DO NOT HAVE ADEQUATE RESPONSE TO BISPHOSPHONATE TREATMENT: A RANDOMIZED CONTROLLED TRIAL. Hong-Kong Objectives: To evaluate the efficacy of denosumab on BMD in patients receiving long-term glucocorticoids who do not have satisfactory response to bisphosphonate treatment.

6 Methods: The inclusion criteria : (1) adult patients ≥18 years of age; (2) Daily dose of prednisolone ≥2.5mg within 3 months of study entry; (3) Inadequate BMD response or the development of new fracture despite bisphosphonate treatment for ≥2 years. 40 Participants were randomized to receive either: (1) Denosumab (60mg SQ /6 mo) + discontinuation of Bph or (2) Continuation of oral bisphosphonates (control group). Calcium (3g/day of caltrate), vitamin D (rocaltrol 0.25ug/day) and other medications as usual. Baseline and follow-up BMD (femoral neck, femoral trochanter, total hip, lumbar spine and whole body) at 6 and 12 months Markers of bone turnover (serum osteocalcin, serum P1NP, serum CTX, and urine DPD) were also assayed at the same time points. The primary outcome was the BMD change in the lumbar spine at month 12 compared to baseline.

7 Results: At month 12, a significant gain in BMD at the lumbar spine (+3.4±0.9%; p=0.002) and the hip (+1.4 ± 0.6%; p=0.03) observed in denosumab-treated patients. The increase in BMD of the spine and total hip was not statistically significant in the control group of patients. No new fractures occurred in the participants at month 12. Minor upper respiratory tract infection was numerically more commonly reported with denosumab (30% vs 10%) while other adverse events occurred at similar frequency between the two groups. One patient of each group was withdrawn from the study because of non-compliance to treatment. None of the patients withdrew from study because of adverse events.

8 Conclusion: In patients receiving long-term glucocorticoids but not having adequate response to bisphosphonates, denosumab was effective in raising the BMD at the spine and hip after 12 months’ therapy. Denosumab was well tolerated.

9 ONE-YEAR EFFECTS OF GLUCOCORTICOIDS ON BONE DENSITY. A META-ANALYSIS IN COHORTS OF PATIENTS ON HIGH AND LOW DOSE THERAPY. Amesterdam Objectives: To investigate GC-induced bone loss in patients with chronic inflammatory diseases (low dose) or transplants (high dose) through a metaanalysis of cohorts. Methods: A search of published studies in PubMed (1995 – 2012), Cochrane databases (1995 – 2012), EMBASE (1995 – 2012), and bibliographic references extending and expanding a previous systematic review on chronic disease up to articles(n=1565pts) CID, 16 articles (n=635) transplant pts. Study selection: Prospective studies were included of patients receiving GC who underwent at least 2 BMD measurements by DEXA over a period of at least 8 months. Only supplementation with calcium and/or Vitamin D3 was allowed. Cohorts studying patients using bisphosphonates or other anti- osteoporotic drugs or diseases associated with influence on bone loss were excluded. Primary outcome was the one-year change in lumbar spine BMD; secondary outcome the change in femoral neck BMD.

10 Results: In the chronic inflammatory diseases group (both starters and chronic users): mean daily dose of GC = 8,8 mg (1.2 – 16.4). Bone loss at the lumbar spine= -1.8% [95%CI: -2.2; -1.3]. Only 39 cohorts (N=1255) also measured femoral neck; in these bone loss was -1.5% [-2.1; -0.9] in the lumbar spine, and -1.3% [-1.8; -0.8] in the femoral neck. In the transplantation group (almost all starters) the mean daily dose of GC was 20.4 mg (7.7 – 52.7). Bone loss at the lumbar spine was -4.9%[-6.6; -3.1]. Only 18 cohorts (N=551) also measured femoral neck; in these bone loss was -4.1% [-6.0; -2.2] in the lumbar spine, and -3 [-4.8; -1.3] in the femoral neck.

11 BMD % change from baseline. The graph depicts individual studies, weighted mean and 95%CI.

12 Conclusions: This meta-analysis provides definitive data on one-year bone loss across a range of diseases and GC doses. It shows GC treatment at the high doses used in transplantation patients leads to considerable bone loss, especially in the lumbar spine. In contrast, bone loss is limited during GC treatment at the lower doses used in chronic inflammatory disease. Existing guidelines should be updated to reflect this data

13 NOVEL GLUCOCORTICOIDS AND GLUCOCORTICOID RECEPTOR LIGANDS: TEACHING OLD DRUGS NEW TRICKS. Charite, Berlin Selective GR agonists (SEGRAs). This approach is based on the suggestion that some GC actions (the so called transrepression effects) are to a greater extent responsible for desirable anti-inflammatory and immuno modulating effects than the other actions (the so called transactivation effects) that are associated with frequently occurring side effects (but also with some immunosuppressive activities). The idea of developing SEGRAs is to use transrepression mediated GC effects almost exclusively thereby inducing potent GC therapeutic activity with reduced side effects. (ongoing study, USA, www. clinicaltrials.gov)

14 Other targeted molecules Targeted delivery of GC using liposomal formulations: ongoing study. Prednisone + dypiridamole combination: not > prednisone alone. Development stopped.

15 Chronotherapeutic prednisone formulation MR/DR prednisone: release 4h after ingestion 2 studies: CAPRA-1: MR prednisone : clinically superior to the conventional immediate release preparation with respect to reducing morning joint stiffness and clinical control of the disease. Same safety profile. CAPRA-2:

16 CAPRA-2: 12-week, double-blind, placebo-controlled trial. MR prednisone 5 mg once daily plus DMARD therapy resulted in higher response rates for ACR20 and ACR50, and a greater median relative reduction from baseline in morning stiffness (22%) at week 12 compared with placebo plus DMARD therapy. Significantly greater reductions in severity of RA and fatigue, as well as a greater improvement in physical function were seen at week 12 with MR prednisone compared with placebo. The incidence of adverse events was similar for MR prednisone and placebo.

24 When to Treat?

25 Why treating UA? Why treating early? Systematic Literature Review Strong evidence that the timing of intervention is associated with the severity of radiological progression

26 Relationship of prolonged symptom duration and DMARD free sustained remission General “the earlier the better” principle Window of Opportunity Early treatment is beneficial at any point in time Specific time frame in which disease is more susceptible no treatment

27

28 What are relevant disease outcomes for UA-patients? Perhaps not: fulfilling classification criteria for RA Not any more: Structural damage Persistence of the disease = Chronic use of medication / DMARDs Functioning

29 Prediction of persistence within early UA (or RA) A model predicting persistence within UA or within RA lacking Validated risk factors for persistence:  ACPA/RF  Symptom duration

69 SIGNATURE OF CIRCULATING MICRORNAS IN OSTEOARTHRITIS C. Beyer et al. Eular 2014, Paris, juin 2014 Etude de phase IV randomisée contre placebo: 22 patients ayant une gonarthrose traités pendant 4 mois par chondroïtine sulfate (CS 800 mg/j) et 27 patients traités par placebo. Seul le paracétamol était autorisé lors de l’étude comme traitement dit de « sauvetage ». La réponse à une stimulation douloureuse par pression rotulienne ou de l’interligne fémoro-tibiale interne était évaluée par IRM cérébrale fonctionnelle Après 4 mois de traitement, cliniquement, la pression rotulienne tendait à être moins douloureuse dans le groupe CS.

Pas d’effet de la CS avec le test de pression de l’interligne articulaire interne, possiblement plus complexe en terme de stimulation douloureuse que la pression rotulienne

70 UPDATED EULAR EVIDENCE-BASED RECOMMENDATIONS FOR THE MANAGEMENT OF GOUT P. Richette et al. Eular 2014, Paris, juin Recevoir des informations sur la physiopathologie de la maladie, l’existence de traitements efficaces, des comorbidités associées, et les principes des traitements des crises et des traitements hypouricémiants (THU) au long cours (FR=9) 2.Recevoir des conseils sur l’hygiène de vie : perte de poids si nécessaire, arrêt de la consommation des alcools (en particulier bières et spiritueux) et des sodas sucrés, éviter des consommations excessives de viandes et de poissons. Des produits peu gras sont conseillés ainsi que des exercices physiques réguliers (FR=9) 3.Avoir un dépistage des comorbidités et des facteurs de risque cardiovasculaire : maladie rénale chronique, insuffisance coronarienne et cardiaque, artériopathie des membres inférieurs, diabète, HTA, dyslipidémie, obésité, tabac. Il s’agit d’une prise en charge globale de la maladie goutteuse (FR=9) 4.Substituer, si possible, un traitement par diurétique de l’anse ou un thiazidique. En cas d’hypertension, préférer un traitement par losartan ou inhibiteur calcique et en cas de dyslipidémie, une statine ou le fénofibrate (FR=9) 5.Le traitement des crises doit être débuté le plus tôt possible dès les premiers signes et les prémices reconnus par le patient. L’éducation pour l’automédication des crises est recommandée. Le choix du traitement dépend des contre-indications, de l’expérience antérieure des patients, du délai de prescription par rapport au début de la crise, et du nombre et du site de l’articulation touchée (FR=9)

71 UPDATED EULAR EVIDENCE-BASED RECOMMENDATIONS FOR THE MANAGEMENT OF GOUT P. Richette et al. Eular 2014, Paris, juin Les traitements recommandés en première intention sont : colchicine (si crise durant moins de 12 heures) avec une dose de charge de 1 mg suivie une heure plus tard de 0.5 mg pour le premier jour ; AINS (associée à un IPP si besoin), corticothérapie orale (30-35 mg/j d’équivalent de prednisone pendant 3 à 5 jours), ou en injection intra-articulaire. Colchicine et AINS ne sont pas indiqués en cas d’insuffisance rénale.

79 1. PATHOGENIC MECHANISMS IN GIANT-CELL ARTERITIS

80 SP0002 Giant cell arteritis: new perspectives PATHOGENIC MECHANISMS IN GIANT-CELL ARTERITIS M.C. Cid, on behalf of Vasculitis Research Unit. Systemic Autoimmune Diseases, Hospital Clinic, University of Barcelona, IDIBAPS, Barcelona, Spain

81 Giant-cell arteritis (GCA) is a chronic inflammatory disease of large vessels. The epidemiology of GCA suggests that a genetic background plays a role in its pathogenesis. Several polymorphisms have been associated with increased susceptibility to GCA, but the strongest association has been found with MHC class II variants, supporting the concept that GCA is an antigen-driven disease

82 Activated dendritic cells are present in lesions and considered to play an important role in T-cell activation. GCA is characterized by a marked Th1- mediated immuneresponse with strong expression of IFNγ. Th17 immune response also contributes to GCA and patients with prominent IL-17 expression respond better to glucocorticoid treatment.

83 Amplification cascades following initial events are crucial in the development and maintenance of GCA lesions. IFNγ is a potent activator of macrophages which produce pro-inflammatory cytokines IL-1, TNFα and IL-6, among others. Tissue expression and serum concentrations of TNFα and IL-6 are associated with persistent/relapsing disease. Chemokines and adhesion molecules are also expressed in lesions and amplify inflammatory loops. Angiogenic factors promote neovascularization, providing new entries for infiltrating leukocytes.

84 Currently, GCA treatment relies on glucocorticoids which induce a dramatic improvement of symptoms but are unable to achieve sustained remission in % of patients. The association between increased expression of TNFα and persistent disease activity led to the performance of clinical trials blocking TNF with various agents which, unfortunately, have not been able to maintain remission, probably due to redundancy in cytokine pathways.

85 Currently, blocking IL-6 receptor with tocilizumab or interfering with CD28-mediated T-cell co-stimulation with abatacept, are being tested in multi-centre clinical trials. IL-6 is a multifunctional cytokine involved not only in inducing the acute phase response and related symptoms but also in maintaining the activation of the Th17 pathway.

86 Growth factors produced by activated macrophages or by injured vascular smooth muscle cells induce myofibroblast differentiation, migration and production of matrix proteins, leading to intimal hyperplasia and vessel occlusion, source of the ischemic complications in GCA. PDGFs, TGFβ and endothelin-1, may contribute to myofibroblast activation. Their expression in lesions is not down-regulated by glucocorticoids suggesting that mechanisms of vessel occlusion may require a specific approach.

90 Ultrasonography in diagnosis

91 AB0476 THE DIAGNOSTIC VALUE OF ULTRASONOGRAPHY-DERIVED EDEMA OF THE TEMPORAL ARTERY WALL (DARK HALO SIGN) IN GIANT CELL ARTERITIS: A SECOND META-ANALYSIS A. Arida, M. Kyprianou, M. Kanakis, P. Sfikakis First Department of Propaedeutic and Internal Medicine, Laikon Hospital, Athens University Medical School, Athens, Greece

92 Objectives: Ultrasonography of temporal arteries is used by many in the diagnostic approach of patients with suspected giant cell arteritis (GCA) in clinical practice. A meta-analysis of primary studies available through April 2004 concluded that ultrasonography could indeed be helpful in diagnosing GCA (Ann Intern Med 2005;142: ). We specifically re-examined the diagnostic value of the ultrasonography-derived halo sign.

93 Conclusion: Temporal artery edema demonstrated as dark halo sign should be always looked for in ultrasonography when GCA is suspected. Providing that currently accepted technical quality criteria are fulfilled, halo sign’s sensitivity and specificity seem comparable to those of established autoantibody measurements used in the classification criteria of rheumatoid arthritis and systemic lupus erythematosus. Validation of revised GCA classification criteria which will include the halo sign may be warranted.

94 3. Monitoring response of therapy by imaging

95 AB0454 GIANT CELL ARTERITIS MONITORING WITH COLOUR DOPPLER ULTRASONOGRAPHY C. Castillo, E. De Miguel, E. Martin-Mola Rheumatology, Hospital Universitario La Paz, Madrid, Spain

96 Background: Erythrocyte sedimentation rate (ESR) is, in addition to medical progress, the most common tool used to monitor patients with giant cell arthritis (GCA). However, there are patients diagnosed with GCA with normal or low ESR. Other conditions, such as infections or anemia, may increased the ESR. Objectives: To assess disease activity in patients with GCA with colour Doppler ultrasonography (CDUS) when compared to ESR.

97 We studied 42 patients with GCA, 16 female and 26 male. The mean age was years (SD ±7.5 years, range: years). Complete resolution of ultrasound signs of GCA took weeks on average. Baseline ESR was 66.96mm/h on average (SD 27.18mm/h). The mean drop in ESR after complete GCA ultrasound signs disappearance, was 22.10mm/h (SD 17.71mm/h) with a significant decrease compare to the baseline ESR (p<0,0001).

98 The mean ESR of the group without halo was 22.10mm/h (n=28), in the group with 1 branch involved (n=20) the mean ESR was 26.85mm/h, in the group with 2 branches involved (n=27) it was 50.96mm/h, in the group with 3 branches involved (n=14) it was 34mm/h, and finally, in the group with 4 branches with halo sign (n=27) the mean ESR was 52.59mm/h. Differences between groups were statistically significant when compared to the ESR (p<0.001).

99 Conclusion: CDUS can objectively assess the edema in the vessels of patients with GCA, and have concurrent validity when compared to the ESR. In addition, it is an useful tool to monitor patients with normal ESR and to avoid bias of concomitant diseases.

100 SP0003 THE ROLE OF IMAGING MODALITIES IN THE DIAGNOSIS AND FOLLOWUP OF GIANT CELL ARTERITIS N. Pipitone. Rheumatology, Reggio Emilia, Italy Imaging studies have proved useful to detect inflammatory changes in the temporal arteries, and are invaluable in demonstrating inflammation in large arteries, which are not easily accessible to biopsy. Color-Doppler sonography (CDS), magnetic resonance (MR) angiography (MRA) and contrast-enhanced computerized tomography (CT) angiography (CTA) can visualize both the arterial wall and the lumen. All these techniques can aid in diagnosing early arteritis by demonstrating inflammation of the arterial wall even before vascular complications such as stenoses and aneurysms develop.

101 Precocious inflammatory signs of arteritis include vessel wall thickening and transmural edema, which shows as a hypoechoic “halo” surrounding the lumen of an inflamed artery on CDS and as contrast enhancement on MRA and CTA. CDS is particularly suited to investigate the superficial arteries (including the temporal arteries), while CT and MR are able to depict well deep, large vessels such as the thoracic and abdominal aorta, which can hardly or not be visualized by CDS. Alternatively, large-vessel inflammation can be assessed by 18F-Fluorodeoxyglucose positron emission tomography (PET)

102 However, PET cannot demonstrate changes in the temporal or renal arteries. Moreover, PET is unable to delineate the anatomical details of the arterial wall, and is thus not helpful in detecting stenoses or aneurysms. For monitoring purposes, CDS, MRI/MRA, and CT/CTA are helpful in that they can demonstrate both arterial wall and lumen changes. PET can also be used to monitor the extent and intensity of vascular inflammation in large vessels.

103 AB0565 CAN COLOR DOPPLER ULTRASOUND BE USED TO MONITOR TREATMENT RESPONSE IN LARGE VESSEL GIANT CELL ARTERITIS? A. Diamantopoulos, G. Haugeberg, G. Myklebust, on behalf of SONOVAS Study Group. Rheumatology, Hospital of Southern Norway Trust, Kristiansand S, Norway

104 Background: On ultrasound examinations large vessel vasculitis (LVV) has been reported to be present in up to 37% of giant cell arteritis (GCA) patients. In these patients, the axillary arteries are reported to be affected as high as 98% Color Doppler ultrasound (CDUS) yields a high sensitivity and specificity to diagnose GCA. Objectives: The aim of this study was to examine if CDUS of the axillary arteries could be used to monitor treatment response in LVV-GCA.

105 Conclusions: CDUS of the axillary arteries seems to be a useful tool to monitor treatment response in LVV-GCA. Thus, CDUS of the large vessels has the potential to be used for the assessment of disease activity in LVV-GCA patients. These promising results have to be confirmed in larger cohorts of patients.

106 3. Ultrasonography and temporal artery biopsy

107 OP0056 CAN WE REPLACE TEMPORAL ARTERY BIOPSY WITH CRANIAL ULTRASOUND FOR THE DIAGNOSIS OF GIANT CELL ARTERITIS? A RETROSPECTIVE COHORT STUDY OF THE DIAGNOSTIC UTILITY OF ULTRASOUND IN ROUTINE CLINICAL PRACTICE A. Croft, N. Thompson, M. Duddy, F. Khattak, S. Mollan, P. Jobanputra. Queen Elizabeth Hospital, Birmingham, United Kingdom

108 Background: Temporal artery biopsy (TAB) has historically been considered the “gold standard” diagnostic test for Giant Cell Arteritis Objectives: The aim of this study was to evaluate the diagnostic utility of cranial duplex ultrasound (CDUS) in patients with a suspected diagnosis of GCA in routine clinical practice.

109 Results: A total of 87 patients underwent CDUS for suspected GCA. 36 patients (41%) had a confirmed clinical diagnosis at 3-month follow-up. When compared to clinical diagnosis at 3 months, the sensitivity of CDUS was 81%, specificity 98%, positive likelihood ratio 41, negative likelihood ratio 0.2, positive predictive value of 97% and negative predictive value of 88%. In contrast, when compared to clinical diagnosis at 3 months, TAB had a sensitivity of 53%, specificity 100%, positive likelihood ratio 2.3, negative likelihood ratio 0.2, positive predictive value of 100% and negative predictive value of 47%.

110 Conclusions: CDUS had a greater sensitivity than TAB and a comparable specificity to diagnose GCA. The CDUS result was the strongest predictor for a diagnosis of GCA at 3 months, whereas ACR criteria when used alone were insufficiently specific to accurately predict or exclude the diagnosis of GCA at 3 months. In contrast, the high positive and negative predictive value of CDUS over TAB indicates that TAB may be unnecessary particularly where clinical suspicion of GCA is high or quite low.

Dasgupta Rheumatology,Southend University Hospital, Westcliff-on-Sea, United Kingdom; Rheumatology, Medical University Graz, Graz, Austria

112 Background: Temporal artery ultrasound (TAUS) is increasingly used in the diagnosis of giant cell arteritis (GCA). Vessel wall edema (Halo) is suggestive of GCA. Objectives: To investigate whether the extent & severity of temporal and axillary artery edema (Halo Score, HS) or the number of affected arterial branches is associated with clinical and laboratory characteristics and TAB findings in newly diagnosed GCA.

113 Conclusions: The diagnostic sensitivity and specificity of CDS-TA for diagnosing GCA is comparable, if not superior to TAB. In case of characteristic sonographic changes, CDS-TA may obviate the need for TAB.

Hoˇcevar, Ž. Rotar, M. Tomšiˇc. Department of Rheumatology, University Medical Centre Ljubljana, Ljubljana, Slovenia Objectives: To evaluate the diagnostic value of CDS-TA in suspected GCA cases in daily clinical practice.

115 Background: Temporal artery ultrasound (TAUS) is increasingly used in the diagnosis of giant cell arteritis (GCA). Vessel wall edema (Halo) is suggestive of GCA. Objectives: To investigate whether the extent & severity of temporal and axillary artery edema (Halo Score, HS) or the number of affected arterial branches is associated with clinical and laboratory characteristics and TAB findings in newly diagnosed GCA.

116 Conclusions: Our findings support vascular ultrasound as a useful non-invasive investigation in GCA. Halo findings were associated with demographic, clinical and laboratory features in GCA. Halo score was able to predict positive TAB findings. A high HS may replace the need for diagnostic TAB in some cases.

117 AB0597 FDG PET-CT VERSUS TEMPORAL ARTERY BIOPSY IN PATIENTS PRESENTING WITH GCA/PMR: A RETROSPECTIVE CROSS-SECTIONAL STUDY S.A. Just, R.A. Gildberg-Mortensen, R.A. Andreasen, N. Lomborg, M.B. Morillon, I.M.J. Hansen. Department of Medicine, Svendborg Hospital, Odense University Hospital (OUH), Svendborg, Denmark

118 Background: Giant Cell Arteritis (GCA) is a large vessel vasculitis, which can occur concomitant with Polymyalgia Rheumatica (PMR). Both diseases may also be seen as isolated disease entities. The two conditions are treated differently, and therefore correct diagnosis is essential. Positron-emission tomography (PET) is receiving increasing attention in the diagnostics of both GCA and PMR.

119 In GCA FDG uptake is often seen in the large vessels of the thorax and neck – hereafter called vasculitis pattern. In isolated Polymyalgia Rheumatica (PMR) uptake can be seen in the ischial tuberosities, the greater trochanters, and the lumbar spinous processes – hereafter called PMR pattern. Temporal artery biopsy is part of the diagnostic workup when GCA is suspected, confirming the diagnosis if characteristic vasculitis histology is found.

120 Objectives: To describe the sensitivity and specificity of vascular FDG uptake on PET-CT compared to temporal artery biopsy result, in suspected GCA and/or PMR.

121 Results: Information about 118 patients was retrieved. 83 of these had been diagnosed with isolated PMR, and 36 with GCA with or without PMR. 32 patients had undergone both FDG PET-CT scan and temporal artery biopsy at presentation (19 PMR and 13 GCA). PET-CT FDG uptake pattern: PET-CT FDG vasculitis uptake had a sensitivity of 78% (7/9) and a specificity of 78% (18/23). The positive and negative predictive value was 58% (7/12) and 90% (18/20), respectively.

122 Conclusions: This study shows that FDG PET- CT, as a measure of vascular involvement in suspected GCA and/or PMR, should be used with caution.

123 4. Management of resistant to treat PMR/GCA

124 SP0060 HOW TO MANAGE RESISTANT POLYMYALGIA RHEUMATICA/GIANT-CELL ARTERITIS C. Cid Systemic Autoimmune Diseases, HOSPITAL CLINIC. UNIVERSITY OF BARCELONA. IDIBAPS, Barcelona, Spain Abstract: Resistant giant-cell arteritis (GCA) may include a variety of clinical situations that may need to be differently and specifically addressed.

125 GCA symptoms or some complications may not completely respond to standard therapy during the induction of remission period or may recur during follow-up. In some instances, incomplete initial response may be due to misdiagnosis, particularly when diagnosis exclusively relies on clinical grounds. GCA may be mimicked by a variety of diseases including amyloidosis and other systemic vasculitides. Even biopsy-proven GCA may be sometimes equivocal and vascular or inflammatory diseases such as thromboangiitis obliterans or other systemic vasculitis may involve the temporal arteries.

126 Approximately 50% of patients with GCA follow a relapsing course when corticosteroids are tapered and may cumulate disease or treatment -related morbidity. For patients with relapsing disease, there are not definitely demonstrated options with clear efficacy. Among common immunosuppressive agents, only methotrexate has shown a modest corticosteroid –sparing effect in a meta-analysis of 3 randomized controlled trials. Insufficient understanding of the pathogenesis of the disease and the mechanisms involved in the persistence of inflammatory activity prevents the identification of suitable therapeutic targets.

127 Immunopathologic studies have shown that increased expression of TNFalpha in lesions and elevated circulating concentrations of TNFalpha are associated with disease persistence. However, blocking TNF alpha with infliximab has not demonstrated benefit over placebo in maintaining corticosteroid-induced remission in a randomized controlled trial. A few studies suggest that IFN gamma and IL2p40 expression may be associated with disease persistence, and these potential targets deserve further investigation. Other immunosuppressive or biologic agents have been tested in insufficiently powered studies (etanercept, azathioprine), in retrospective series, or in isolated case reports or small series.

130 Background: More than one million herpes zoster (HZ) cases occur in the United States every year. Currently, the live zoster vaccine is recommended for healthy older patients age ≥60 years. Whether the absolute risk for younger patients who have autoimmune or inflammatory conditions might be high enough to warrant vaccination of younger patients with these diseases is unclear. Objectives: To evaluate the overall and age-stratified absolute incidence of HZ infections associated with different autoimmune and inflammatory diseases compared to the general population currently recommended for vaccination by the CDC.

131 Table 1. Age, gender standardized incidence rate for herpes zoster per 1000 pys Cohorts All Male Female SLE IBD RA Psa AS Gout Diabetes Healthy The age-specific rate of HZ for RA, IBD and SLE patients age ≥40 was greater than the corresponding rate in healthy individuals age ≥60.

132 Conclusions: SLE, IBD and RA are associated with an increased incidence rate of HZ infection compared to healthy older people. Based upon comparable absolute risk to healthy individuals age ≥60, SLE, IBD and RA patients age ≥40 might reasonably be considered as appropriate candidates for vaccination for HZ.

192 THE DEGREE OF ACTIVITY MEASURED WITH THE EULAR-SS DISEASE ACTIVITY INDEX (ESSDAI) STRONGLY CORRELATED WITH DEATH IN PATIENTS WITH PRIMARY SJOGREN SYNDROME (GEAS-SS REGISTRY) To analyse the association between the new (ESSDAI) and death in a large cohort with primary Sjogren syndrome (pSS) The degree of activity measured in the majority of domains of the ESSDAI strongly correlated with mortality. – Activity of constitutional and lymphadenopathy domains (closely related to lymphoma) correlated with death – Extraglandular sites of involvement (in which high doses of corticosteroids and immunosuppressive agents are used) correlated principally with death caused by infection.

193 EFFICACY OF RITUXIMAB IN SYSTEMIC MANIFESTATIONS OF PRIMARY SJOGREN’S SYNDROME O. Logvinenko et al Russian Federation 24 patients with systemic lesions. (+/- BAFF) MONO 9 RTX COMBINATION 14 CYCLO+RTX. At month 3 after RTX therapy, a clinical complete and partial response was observed in 71.4% (15/21) and 19% (4/21) cases, respectively. A complete/ partial immunologic response was presented in 52.6% (10/19)/26.3% (5/19)patients. At month 6 clinical and immunologic relapse was noted in 25% (5/20) and 35.3% (6/17) cases, respectively. There was decrease median ESSDAI score from 8 (7-10) at baseline to 3 (2-4) at month 3 and to 3 (2-5) at month 6 (p<0.001). NO changes in sicci syndrome.

194 PATTERNS OF INFLAMMATION AND DYSFUNCTION OF THE SALIVARY GLANDS IN PATIENTS NEWLY DIAGNOSED WITH SJOGREN’S SYNDROME Objectives: – To estimate the frequency of various patterns of inflammation and dysfunction of the salivary. – To compare clinical and serological features of pSS patients stratified into four different subgroups on the basis of the degree of lymphocytic infiltration detected in MSGB and on the variation of the salivary flow rate.

209 FIRST EULAR Imaging Recommendations for SpA The first choice for diagnosing sacroiliitis should be conventional radiography of the sacroiliac joint. MRI (magnetic resonance imaging) is an alternative in selected cases. To detect peripheral enthesitis as well as peripheral arthritis, tenosynovitis, or bursitis in these cases, either ultrasound or MRI is appropriate. To assess and monitor disease activity, MRI of the sacroiliac joint is recommended. To monitor long-term for structural damage and especially new bone formation, conventional radiology of the sacroiliac joint and/or spine is acceptable and appropriate. 209ZIADE 2014 SP0143

210 FIRST EULAR Imaging Recommendations for SpA To assess suspected spinal fracture, conventional radiology is recommended as the initial method. To assess for osteoporosis in cases of axial SpA without radiographic evidence of syndesmophytes in the lumbar spine, dual emission x-ray absorptiometry of the hip and spine is in order. To detect syndesmophytes (and predict development of new syndesmophytes), initial conventional radiographs of the lumbar and cervical spine are "recommended" but MRI of vertebral corner inflammatory lesions "may also be used.” 210ZIADE 2014 SP0143
