Ultrasound definition of subacromial chronic "fibro-adhesive" bursitis and its treatment via ultrasound guided hydrodilation: a prospective pilot study. J Ultrasound 2024:10.1007/s40477-024-00894-9. [PMID: 38703325 DOI: 10.1007/s40477-024-00894-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 03/10/2024] [Indexed: 05/06/2024] Open
Abstract
PURPOSE The shoulder pain is one of the main causes that lead the patient to medical evaluation. Today, the ultrasound (US) represents an essential tool in the orthopaedical, rheumatological and rehabilitative setting to address the musculoskeletal causes of pain. Amongst the commonest causes of shoulder complains lay the frequent subacromial chronic bursitis (SACB). In this condition, the thickening of the bursal walls and subsequent fusion of the two synovial sheets leads to the reciprocal loss of bursal walls gliding under the subacromial space and consequently pain. This condition represents a common cause of shoulder pain and may be easily addressed by musculoskeletal sonographers. The purpose of this paper will be to describe the US appearance of SACB and to evaluate the efficacy of US-guided hydrodilation in its treatment. METHODS We included patients with painful shoulder attending our outpatient clinic for shoulder complains with the diagnosis of SACB with a bursal wall > 1.5 mm. A group was treated via US-guided hydrodilation, while the control group was treated via a classical blind approach using triamcinolone acetonide. Both groups underwent the same rehabilitation program following the injections. The shoulder functionality was assessed via qDASH questionnaire at baseline, days 3, 7, 14, 30, 60, and 90. A p <0.05 was considered significant. RESULTS Both groups displayed a significant reduction of pain; nevertheless, in the group treated with US-hydrodilation, there was no need for re-treatment. CONCLUSIONS The US-guided hydrodilation for SACB should be the preferred technique to detach bursal walls and improve patient symptoms, since it requires fewer invasive maneuvers.

How to inject sacroiliac joints with ultrasound guidance: a pictorial essay. J Ultrasound 2024:10.1007/s40477-024-00899-4. [PMID: 38582820 DOI: 10.1007/s40477-024-00899-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Accepted: 03/21/2024] [Indexed: 04/08/2024] Open
Abstract
Active sacroiliitis and sacroiliac joint dysfunction represent a common cause of low back pain in the population and are cause of patients' quality of life reduction and disability worldwide. The use of musculoskeletal ultrasound allows to easily identify the sacroiliac joints and to study every pathological condition affecting its most dorsal part; moreover, musculoskeletal ultrasound allows to guide highly effective injective procedures aimed at improving patients' symptoms and enhance their well-being. This paper aims to briefly explain for the musculoskeletal sonographer the anatomy and biomechanics of the sacroiliac joints, the correct ultrasound scanning method for their visualization and the most appropriate ultrasound guided injection technique to help dealing with the diagnostic and management of sacroiliac joint pain in the everyday scenario.

Subclinical giant cell arteritis increases the risk of relapse in polymyalgia rheumatica. Ann Rheum Dis 2024; 83:335-341. [PMID: 37932008 DOI: 10.1136/ard-2023-224768] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 10/24/2023] [Indexed: 11/08/2023]
Abstract
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.

Efficacy and Safety of Upadacitinib in Rheumatoid Arthritis: Real-Life Experience from a Prospective Longitudinal Multicentric Study. J Clin Med 2024; 13:401. [PMID: 38256535 PMCID: PMC10816893 DOI: 10.3390/jcm13020401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 12/31/2023] [Accepted: 01/06/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND We provide the first prospective longitudinal multicenter experience on Upadacitinib efficacy and safety profile in Rheumatoid Arthritis (RA) in a real-life context, focusing on clinimetric and ultrasonographic (US) data. METHODS RA patients referred to three Italian tertiary Centers who started Upadacitinib were enrolled as per ACR/EULAR classification criteria and prospectively reviewed. The primary aim of this study was to assess changes in clinimetric and ultrasonographic scores through time (at baseline, after 1 month, 3 months, and 6 months from the beginning of the therapy). Secondary aims were to: (i) estimate the impact of biologic lines of treatment and concomitant therapies on response to therapy; (ii) explore changes in laboratory parameters; and (iii) find potential predictive factors associated with response to therapy. RESULTS Seventy-one patients (49 Females and 22 Males) were included. Clinimetric scores, including the Disease Activity Score (DAS28-CRP) and Simplified Clinical Disease Activity Index (SDAI), and US findings (synovial hypertrophy and power Doppler) significantly improved (p = 0.029, p = 0.001, p = 0.001, p = 0.001, respectively). Regression analysis revealed a significant association between the concomitant csDMARDs therapy at baseline and the lack of improvement in synovial hypertrophy [OR -4.824, p = 0.010] as well as with DAS28-CRP [OR -0.690, p = 0.045], whereas the presence of increased ESR or CRP at baseline was able to predict a significant improvement in SDAI [OR 8.481, p = 0.003]. No adverse events, such as deep venous thrombosis, pulmonary embolism, or herpes zoster virus infection, were reported during this study observation. CONCLUSION Our real-life experience confirms the efficacy of Upadacitinib in terms of clinical and ultrasonographic improvement, as well as displaying a good safety profile.

The Role of Major Salivary Gland Ultrasound in the Diagnostic Workup of Sicca Syndrome: A Large Single-Centre Study. Tomography 2024; 10:66-78. [PMID: 38250952 PMCID: PMC10820458 DOI: 10.3390/tomography10010006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 12/28/2023] [Accepted: 01/03/2024] [Indexed: 01/23/2024] Open
Abstract
(1) Objective: To determine the diagnostic accuracy of major salivary gland ultrasonography (SGUS) in primary Sjogren's syndrome (SS), we used the Outcome Measures in Rheumatology Clinical Trials (OMERACT) scoring system on a large single-centre cohort of patients with sicca syndrome. (2) Method: We retrospectively collected the clinical, imaging and serological data of all the patients referred with a suspicion of SS who underwent SGUS and minor salivary glands biopsy. (3) Results: A total of 132 patients were included. The SGUS scores were correlated between the two sides (p < 0.001). The diagnostic cut-off for SS (AUROC: 0.7408) was 6 for the SGUS-global sum (sensitivity: 32.43%; specificity: 96.84%). The cut-off with the highest specificity for SS diagnosis was 7. In the patients with a final diagnosis of SS, the mean SGUS score was significantly higher (p < 0.001) than that of the non-SS patients (3.73 vs. 1.32 for the SGUS-global sum). A significant correlation was demonstrated between the SGUS scores and final SS diagnosis (p < 0.001), biopsy positivity (p < 0.001), ANA positivity (p = 0.016), Ro-SSA positivity (p = 0.01), and gland fibrosis (p = 0.02). (4) Conclusions: SGUS, using the OMERACT scoring system, has moderate sensitivity and high specificity for the diagnosis of SS. The scoring showed a strong and direct correlation with all the clinical hallmarks of SS diagnosis, such as the positivity of a labial salivary gland biopsy, ANA and Ro-SSA statuses, and salivary gland fibrosis. Because of its high specificity, a SGUS-global score > 6 could be therefore employed for the diagnosis of SS in the case of ANA negativity or the unavailability of a biopsy.

Prevalence and characteristics of subclinical giant cell arteritis in polymyalgia rheumatica. Rheumatology (Oxford) 2024; 63:158-164. [PMID: 37129541 DOI: 10.1093/rheumatology/kead189] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 03/28/2023] [Accepted: 04/16/2023] [Indexed: 05/03/2023] Open
Abstract
OBJECTIVE The main objective of this study was to analyse the prevalence and characteristics of subclinical GCA in patients with PMR. METHODS This was a cross-sectional multicentre international study of consecutive patients with newly diagnosed PMR without symptoms or signs suggestive of GCA. All patients underwent US of the temporal superficial, common carotid, subclavian and axillary arteries. Patients with halo signs in at least one examined artery were considered to have subclinical GCA. The clinical, demographic and laboratory characteristics of the PMR group without subclinical vasculitis were compared with subclinical GCA, and the pattern of vessel involvement was compared with that of a classical single-centre GCA cohort. RESULTS We included 346 PMR patients, 267 (77.2%) without subclinical GCA and 79 (22.8%) with subclinical GCA. The PMR patients with subclinical GCA were significantly older, had a longer duration of morning stiffness and more frequently reported hip pain than PMR without subclinical GCA. PMR with subclinical GCA showed a predominant extracranial large vessel pattern of vasculitic involvement compared with classical GCA, where the cranial phenotype predominated. The patients with PMR in the classical GCA group showed a pattern of vessel involvement similar to classical GCA without PMR but different from PMR with subclinical involvement. CONCLUSION More than a fifth of the pure PMR patients had US findings consistent with subclinical GCA. This specific subset of patients showed a predilection for extracranial artery involvement. The optimal screening strategy to assess the presence of vasculitis in PMR remains to be determined.

Tocilizumab Vs Methotrexate in a Cohort of Patients Affected by Active GCA: A Comparative Clinical and Ultrasonographic Study. Biologics 2023; 17:151-160. [PMID: 38059132 PMCID: PMC10697083 DOI: 10.2147/btt.s431818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 10/31/2023] [Indexed: 12/08/2023]
Abstract
Introduction No head-to-head study has assessed the superiority of tocilizumab versus methotrexate in giant cell arteritis (GCA), and few studies have demonstrated its effectiveness in terms of ultrasonographic findings, but without a control group. The primary endpoint was to assess whether tocilizumab was superior to methotrexate in inducing normalization of US findings, whereas the secondary endpoint was to assess the effectiveness of precocious withdrawal of glucocorticoids. Methods We prospectively enrolled all the patients with active GCA at our clinic. The inclusion criteria were clinical diagnosis of GCA; active disease; and clinical, laboratory, and US data, evaluated using the halo count (HC) and OMERACT GCA Ultrasonography Score (OGUS). Evaluations were repeated at 3, 6, and 12 months. Results Twenty patients were treated with Tocilizumab and 9 with Methotrexate. All but three tocilizumab-treated patients achieved remission at six months, whereas at 12 months, all patients were in glucocorticoid-free remission. Up to three of the nine methotrexate patients experienced a lack of efficacy or minor relapses. Tocilizumab-treated patients showed a statistically significant difference between baseline and all follow-ups in terms of OGUS and HC, whereas the difference in the Methotrexate group was significant after 1 year. The mean glucocorticoid dosage significantly decreased in both groups. No severe adverse events or major relapses were reported. Conclusion Our study demonstrates the superiority in terms of rapidity of a tocilizumab-based scheme over a methotrexate-based scheme in inducing clinical and US remission. Precocious withdrawal of glucocorticoids did not increase the risk of relapse.

Intra-articular injections of biological disease-modifying anti-rheumatic drugs in inflammatory arthropathies: An up-to-date narrative review. Joint Bone Spine 2023; 90:105598. [PMID: 37271277 DOI: 10.1016/j.jbspin.2023.105598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 04/15/2023] [Accepted: 05/08/2023] [Indexed: 06/06/2023]
Abstract
INTRODUCTION Since the 1990s thebiological disease-modifying anti-rheumatic drugs (bDMARDs) have revolutionized the treatment of chronic dysimmune inflammatory arthropathies such as Rheumatoid Arthritis, Psoriatic Arthritis and Axial Spondylarthritis. Nevertheless, despite a full treatment regimen, mono- and oligoarticular persistence of the synovitis is sometimes observed. The intra-articular (IA) use of bDMARD drugs could resolve the persistent joint inflammation and result in a reduction in the degree of immunosuppression of individuals; moreover, the use of these drugs intra-articularly could be associated with a reduction in the treatment-related costs. METHODS We extensively searched via PubMed and Google Scholar articles using as keywords "etanercept", "infliximab", "adalimumab", "certolizumab", "golimumab", "tocilizumab", "ixekizumab", "secukinumab", "rituximab" each combined with "intra-articular injection". RESULTS We found and evaluated 161 papers, and then we selected 24 that were highly related to the topic of the present work. The articles examined a total of 349 patients, 85 males (M), and 168 females (F), mean age of 44.75±12.09 years old and considered 556 treated joints. Three hundred and forty-one patients were affected by Rheumatoid Arthritis, 198 by Psoriatic Arthritis, 56 by Axial Spondylarthritis, 26 by Juvenile Idiopathic Arthritis, 19 by Undifferentiated Arthritis, 1 by arthritis associated with inflammatory bowel disease and 9 patients by an unspecified inflammatory articular disorder. All patients were treated intra-articularly with a TNFα inhibitor among Adalimumab, Etanercept or Infliximab. Side effects were documented in 9 out of 349 (2.57%) treated patients and all were mild or moderate. In some cases the effectiveness of IA bDMARDs treatment was maintained for several months, however in the few published randomized controlled trials(RCTs) the corticosteroids (GCs) appeared to act better when administered intra-articularly compared to bDMARDs. CONCLUSIONS The IA use of bDMARDs seems to be weakly effective in the management of resistant synovitis and not superior to GCs injections. The treatment's main limit appears to be the poor persistence of the compound in the joint.

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. Intern Emerg Med 2023; 18:1929-1939.

Abstract
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.

Abstract
Objectives The aim of this retrospective study was to evaluate baricitinib retention rate in patients affected by rheumatoid arthritis. Secondary aims were to compare the impact on treatment persistence of monotherapy and other variables such as systemic corticosteroid use, line of treatment, disease duration, sex, biomarkers positivity, and Herpes Zoster virus infection. Materials and methods Patients with Rheumatoid Arthritis undergoing baricitinib were consecutively enrolled. Rheumatoid Arthritis diagnosis was performed with 2010 ACR/EULAR classification criteria. The cohort's demographic, clinical and therapeutical data were retrospectively collected. The whole follow-up duration was 104 weeks. Results Ninety-five patients affected by rheumatoid arthritis and treated with baricitinib were consecutively enrolled. At the end of follow-up, the overall retention rate was 69.3%. No statistically significant difference in retention rate was observed between patients treated with baricitinib in monotherapy or in combination with methotrexate (p = 0.638) while patients undergoing a steroidal treatment showed a significantly reduced treatment retention (p = 0.028). Contrarily, patients treated with baricitinib as a first-line b/tsDMARD showed higher drug retention (p = 0.002) compared to further treatment lines. Steroid employment, steroid dosage and previous treatment with bDMARDs correlated with risk of treatment discontinuation and at univariate analysis (p = 0.028, p < 0.001, and p = 0.002 respectively). Multivariate analysis confirmed significance for higher steroid dosage and previous treatment with bDMARDs (p = 0.002 and p = 0.046). No adverse events such as deep venous thrombosis, pulmonary embolism or tubercular infection/reactivation were reported during the study observation. Conclusion Our data show a good baricitinib retention rate after 12 and 24 months of observation (75.1 and 69.3%, respectively). In our cohort, concomitant treatment with methotrexate did not influence treatment persistence while retention was reduced in patients undergoing a steroidal treatment and/or in multi-failure subjects.

Abstract
Beckground Despite the recent advances in the field of autoinflammatory diseases, most patients with recurrent fever episodes do not have any defined diagnosis. The present study aims at describing a cohort of patients suffering from apparently unexplained recurrent fever, in whom non-radiographic axial spondylarthritis (SpA) represented the unique diagnosis identified after a complete clinical and radiologic assessment. Materials and methods Patients' data were obtained from the international registry on Undifferentiated Systemic AutoInflammatory Diseases (USAIDs) developed by the AutoInflammatory Disease Alliance (AIDA) network. Results A total of 54 patients with recurrent fever episodes were also affected by non-radiographic axial SpA according to the international classification criteria. SpA was diagnosed after the start of fever episodes in all cases; the mean age at the diagnosis of axial SpA was 39.9 ± 14.8 years with a diagnostic delay of 9.3 years. The highest body temperature reached during flares was 42°C, with a mean temperature of 38.8 ± 1.1°C. The most frequent manifestations associated to fever were: arthralgia in 33 (61.1%) cases, myalgia in 24 (44.4%) cases, arthritis in 22 (40.7%) cases, headache in 15 (27.8%) cases, diarrhea in 14 (25.9%) cases, abdominal pain in 13 (24.1%) cases, and skin rash in 12 (22.1%) cases. Twenty-four (44.4%) patients have taken daily or on-demand non-steroidal anti-inflammatory drugs (NSAIDs) and 31 (57.4%) patients have been treated with daily or on demand oral glucocorticoids. Colchicine was used in 28 (51.8%) patients, while other conventional disease modifying anti-rheumatic drugs (cDMARDs) were employed in 28 (51.8%) patients. Forty (74.1%) patients underwent anti-tumor necrosis factor (TNF) agents and 11 (20.4%) were treated with interleukin (IL)-1 inhibitors. The response to TNF inhibitors on recurrent fever episodes appeared more effective than that observed with anti-IL-1 agents; colchicine and other cDMARDs were more useful when combined with biotechnological agents. Conclusion Signs and symptoms referring to axial SpA should be inquired in patients with apparently unexplained recurrent fever episodes. The specific treatment for axial SpA may lead to a remarkable improvement in the severity and/or frequency of fever episodes in patients with unexplained fevers and concomitant axial SpA.

Diagnostic role of minor salivary glands biopsy in Sjögren's syndrome: correlations between histology and autoimmunity in a large, monocentric cohort. Reumatologia 2023; 61:109-115. [PMID: 37223369 PMCID: PMC10201380 DOI: 10.5114/reum/163213] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 04/12/2023] [Indexed: 05/25/2023] Open
Abstract
Introduction Based on ACR/EULAR classification criteria, minor salivary glands biopsy (MSGB) is a useful diagnostic tool for the diagnosis of primary Sjögren's syndrome (SS). The main objective of our study was to evaluate the diagnostic role of MSGB, as well as to highlight correlations between histological findings and autoimmune profiles. Material and methods We retrospectively evaluated histological and autoimmunity data from patients who underwent MSGB in our department in cases of suspected SS, from March 2011 to December 2018. Salivary gland samples were evaluated using Chisholm and Mason (CM) grading and the focus score (FS). Results A total of 1,264 patients (108 males, 1,156 females) were included. The median age was 55.22 ±13.51 years (range: 15-87). In univariate binary logistic regression, CM ≥ 3 and FS ≥ 1 were significantly predicted by antinuclear antibodies (ANA), anti-extractable nuclear antigens (ENA) and anti-Ro/SSA titer as well as anti-La/SSB, anti-Ro/SSA, rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) positivity. In multivariate analysis, CM ≥ 3 and MSGB positivity were significantly associated with ANA titer; FS ≥ 1 was not associated with laboratory findings. A positive biopsy was associated with laboratory findings, as ANA and ENA titers, anti-Ro/SSA, anti-La/SSB, RF and ACPA positivity may discriminate patients with SS-related histological findings. Conclusions Minor salivary glands biopsy is a useful tool to diagnose SS in cases of highly suggestive clinical symptoms but in the absence of a specific autoimmunity.

Abstract
OBJECTIVES Rituximab (RTX) is an anti-CD20 chimeric monoclonal antibody recommended as off-label treatment in patients with idiopathic inflammatory myopathies (IIM). The present study aimed to evaluate changes in immunoglobulin (Ig) levels during RTX-treatment and their potential association with infections in a cohort of IIM patients. METHODS Patients evaluated in the Myositis clinic belonging to the Rheumatology Units of Siena, Bari and Palermo University Hospitals, and treated for the first time with RTX were enrolled. Demographic, clinical, laboratory and treatment variables, including previous and concomitant immunosuppressive drugs and glucocorticoid (GC) dosage were analysed before (T0) and after 6 (T1) and 12 (T2) months of RTX treatment. RESULTS Thirty patients (median age, IQR 56 (42-66); 22 female) were selected. During the observational period, low levels of IgG (<700 mg/dl) and IgM (<40 mg/dl) occurred in 10% and 17% of patients, respectively. However, no one showed severe (IgG<400 mg/dl) hypogammaglobulinaemia. IgA concentrations were lower at T1 than T0 (p=0.0218), while IgG concentrations were lower at T2 compared to those at baseline (p=0.0335). IgM concentrations were lower at T1 and T2 than T0 (p<0.0001), as well at T2 than T1 (p=0.0215). Three patients suffered major infections, two others had paucisymptomatic COVID-19, one suffered from mild zoster. GC dosages at T0 were inversely correlated with IgA T0 concentrations (p=0.004, r=- 0.514). No correlation was found between demographic, clinical and treatment variables and Ig serum levels. CONCLUSIONS Hypogammaglobulinaemia following RTX is uncommon in IIM and is not related to any clinical variables, including GC dosage and previous treatments. IgG and IgM monitoring after RTX treatment does not seem useful in stratifying patients who require closer safety monitoring and prevention of infection, due to the lack of association between hypogammaglobulinaemia and the onset of severe infections.

Color Doppler Eye Ultrasonography in giant cell arteritis: differential diagnosis between arteritic and non-arteritic sudden blindness. J Ultrasound 2023; 26:313-320. [PMID: 36550390 PMCID: PMC10063765 DOI: 10.1007/s40477-022-00757-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 11/20/2022] [Indexed: 12/24/2022] Open
Abstract
PURPOSE Temporal (TA) and axillary (AXA) arteries Color Doppler Ultrasonography (CDUS) is the most reliable diagnostic technique for the diagnosis of giant cell arteritis (GCA), displaying high sensitivity and specificity. Nevertheless, CDUS is still poorly performed in the common clinical practice, being employed only by rheumatologists with a relevant expertise in this field. Color Doppler Eye Ultrasound (CDEUS) is a procedure variously employed in ophthalmology and preliminary findings have displayed a possible role also in the diagnostic work-up of GCA. Aim of this study was to assess whether CDEUS may play a role in the differential diagnosis between arteritic and non-arteritic blindness. METHODS We prospectively included all patients evaluated since September 2021 to May 2022 by our Ophthalmology Unit for sudden blindness and referred to our Vasculitis Clinic in the suspicion of GCA. All patients underwent complete ophthalmological evaluation, routine blood tests, AxA and TA CDUS and CDEUS. According to the definite diagnosis, patients were divided in the following subgroups: (A) patients suffering from arteritic central retinal artery occlusion (CRAO), (B) patients suffering from non-arteritic CRAO, (C) patients suffering from arteritic anterior ischemic optic neuropathy (AION), (D) patients suffering from non-arteritic AION. RESULTS During the observational period, we included a total of 25 patients suffering from sudden blindness and referred to Vasculitis Clinic for ruling out GCA. Patients belonging to group A showed no flow or reduced flow within the territory of central retinal artery (CRA), no "spot sign" and positive TA CDUS; on the other hand, patients from group B presented normal TA CDUS, no flow or reduced flow within the territory of CRA and the presence of "spot sign". Conversely, no relevant difference was evidenced at CDEUS in patients with and without arteritic AION. CONCLUSION Our preliminary data displayed a good reliability of CDEUS in distinguishing between arteritic and non-arteritic CRAO, while no difference was assessed between arteritic and non-arteritic AION. Since AION represents the most common presentation of cranial GCA, CDEUS does not seem a reliable procedure in the diagnostic work-up of GCA and should be restricted only to the exclusion of thrombo-embolic occlusions within the territory of central retinal artery.

Peripheral Macrovascular Involvement in Systemic Sclerosis: A Cohort Study by Color and Spectral Doppler Ultrasonography. Life (Basel) 2023; 13:life13020487. [PMID: 36836844 PMCID: PMC9962179 DOI: 10.3390/life13020487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/23/2023] [Accepted: 02/07/2023] [Indexed: 02/12/2023] Open
Abstract
OBJECTIVES Systemic sclerosis (SSc) is a disease characterized by diffuse sclerosis of skin and organs and small vessel vasculopathy. Despite it, large vessels can also be involved with ulnar artery vasculopathy, revealing as a more frequent feature of SSc. The aim of this paper is to assess the macrovascular involvement of SSc patients through an ultrasound (US) evaluation of radial and ulnar arteries. METHODS Radial and ulnar resistance indices (RIs) and peak systolic velocity (PV) (cm/s) together with clinical features of SSc patients were evaluated. Raynaud phenomenon (RP) and healthy control (HC) groups were used for comparison. RESULTS Forty-three SSc patients were evaluated. Twelve patients (28%) had ulnar artery occlusions (UAOs). In nine cases (75%), UAOs were bilateral. A high UAO prevalence (42%) was found in SSc patients with late nailfold-video-capillaroscopy (NVC) pattern (p = 0.0264). Patients with UAOs had digital ulcers (DUs) in 10 cases (83.3%). Radial and ulnar PVs were lower in SSc and RP patients than the HC group. Radial and ulnar RIs were higher in SSc and RP patients than the HC group. A decision tree analysis led to the classification of 70% of SSc patients with an ulnar RI > 0.82 and ulnar PV > 2.8 cm/s. The most influential variables on UAO development were interstitial lung disease (ILD) (p = 0.002) and NVC pattern (p = 0.002). A positive correlation was shown between modified Rodnan skin score (mRSS) and ILD (p = 0.283; r = 0.033), mRSS and DU (r = 0.344; p = 0.012) and DU and ILD (r = 0.303; p = 0.024). Male sex was associated with increased UAO frequency (p = 0.042). CONCLUSIONS UAO is a peculiar feature of severe SSc present in 28% of the cases, particularly associated with the presence of ILD and late NVC pattern. In 75% of the cases, UAOs are bilateral. DUs are very frequent in patients with UAOs (83%). The RI evaluated by US could be useful to distinguish SSc from HC patients. US could be a useful tool for assessing high-risk DU development in patients.

Accuracy of power Doppler ultrasonography in the diagnosis and monitoring of idiopathic inflammatory myopathies. Rheumatology (Oxford) 2023; 62:766-774. [PMID: 35731121 DOI: 10.1093/rheumatology/keac351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 05/19/2022] [Accepted: 06/10/2022] [Indexed: 02/04/2023] Open
Abstract
OBJECTIVES No clear-cut guidelines exist for the use of imaging procedures for the diagnosis of idiopathic inflammatory myopathies (IIM). The aim of the present study was to assess the diagnostic accuracy of power Doppler ultrasonography (PDUS) score in IIM patients compared with a control group and its usefulness during follow-up. METHODS All patients evaluated in the Vasculitis and Myositis Clinic, Rheumatology Unit, University of Siena were prospectively collected. All patients underwent US examination of both thighs in axial and longitudinal scans, which were also performed twice (T1) or three times (T2). RESULTS Forty-five patients with IIM (median [interquartile range] age 55 [45-66] years; 35 female) were enrolled. Receiver operating characteristic curves distinguished patients and controls based on ∑power Doppler (PD), ∑oedema, ∑atrophy and CRP. The best cut-off value for ∑PD was 0.5, ∑oedema 1.5, ∑atrophy 0.5 and CRP 0.22 mg/dl. In a logistic regression analysis, the variables that most influenced diagnosis of IIM were ∑PD and ∑oedema (P = 0.017 and P = 0.013, respectively). ∑Oedema was lower at T1 (P = 0.0108) and T2 (P = 0.0012) than at T0. Likewise, ∑PD was lower at T1 (P = 0.0294) and T2 (P = 0.0420) than at T0. Physician global assessment was lower at T1 (P = 0.0349) and T2 (P = 0.0035) than at baseline. CONCLUSION Our findings show that PDUS is a reliable diagnostic tool in the differential diagnosis between inflammatory and non-inflammatory myopathies. Moreover, PDUS can be employed also during the follow-up of patients with IIM. A reduction in disease activity, measured by physician global assessment, led to a concomitant decrease in both oedema and PD, which was directly correlated with their rate of change. This underlines the close link between clinical assessment and PDUS findings, not only at diagnosis but also during monitoring.

The role of bDMARDs in idiopathic inflammatory myopathies: A systematic literature review. Clin Exp Rheumatol 2023; 22:103264.

Abstract
Idiopathic inflammatory myopathies (IIM) are a group of different conditions typically affecting striate muscle, lung, joints, skin and gastrointestinal tract. Treatment typically relies on glucocorticoids and synthetic immunosuppressants, but the occurrence of refractory, difficult to treat, manifestations, may require more aggressive treatment, borrowed from other autoimmune diseases, including biologic disease modifying drugs (bDMARDs). In this regard, we conducted a systemic literature review in order to depict the current evidence about the use of bDMARDs in IIM. A total of 78 papers, published during the last 21 years, were retrieved. The majority of patients was treated with TNF-α inhibitors, whose effectiveness was assessed particularly in recalcitrant striate muscle, skin and joints involvement. Rituximab, whose evidence is supported by a large number of real-life studies and trials, seems to be an excellent option in case of ILD and anti-synthetase syndrome, while Tocilizumab, despite not meeting primary and secondary endpoints in a recently published clinical trial, proved its effectiveness in rapidly progressing ILD. Similarly, Abatacept, studied in a phase IIb clinical trial with conflicting evidence, was reported to be effective in some case reports of refractory dermatomyositis. Less data exist for anti-IL1 and anti-IL23 agents, which were employed particularly for inclusion body myositis and severe skin disease, respectively. This study provides an organ-focused assessment of bDMARDs in IIM, which display encouraging results in the treatment of refractory subsets of disease.

A Novel Ultrasonographic Anthropometric-Independent Measurement of Median Nerve Swelling in Carpal Tunnel Syndrome: The "Nerve/Tendon Ratio" (NTR). Diagnostics (Basel) 2022; 12:diagnostics12112621. [PMID: 36359465 PMCID: PMC9689936 DOI: 10.3390/diagnostics12112621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 10/18/2022] [Accepted: 10/25/2022] [Indexed: 11/30/2022] Open
Abstract
Background: There is little consensus on ultrasound (US) normative values of cross-sectional area of median nerve (MN-CSA) in carpal tunnel syndrome (CTS) because of its dependency on anthropometric parameters. We aim to propose a novel anthropometric-independent US parameter: MN-CSA/flexor radialis carpi CSA (FCR-CSA) ratio (“Nerve Tendon Ratio”, NTR), in the diagnosis of clinically and electrodiagnostic (EDS)-defined CTS. Methods: 74 wrists of 49 patients with clinically defined CTS underwent EDS (scored by the 1−5 Padua Scale of electrophysiological severity, PS) and US of carpal tunnel with measurement of MN-CSA (at the carpal tunnel inlet), FCR-CSA (over scaphoid tubercle) and its ratio (NTR, expressed as a percentage). US normality values and intra-operator agreement were assessed in 33 healthy volunteers. Results: In controls, the mean MN-CSA was 5.81 mm2, NTR 64.2%. In 74 clinical CTS, the mean MN-CSA was 12.1 mm2, NTR 117%. In severe CTS (PS > 3), the mean MN-CSA was 15.9 mm2, NTR 148%. In CTS, both MN-CSA and NTR correlated with sensitive conduction velocity (SCV) (p < 0.001), distal motor latency (DML) (p < 0.001) and PS (p < 0.001), with a slight superiority of NTR vs. MN-CSA when controlled for height, wrist circumference and weight. In CTS filtered for anthropometric extremes, only NTR maintained a correlation with SCV (p = 0.023), DML (p = 0.016) and PS (p = 0.009). Diagnostic cut-offs were obtained with a binomial regression analysis. In those patients with a clinical diagnosis of CTS, the cut-off of MN-CSA (AUROC: 0.983) was 8 mm2 (9 mm2 with highest positive predictive value, PPV), while for NTR (AUROC: 0.987), the cut-off was 83% (100% with highest PPV). In patients with EDS findings of severe CTS (PS > 3), the MN-CSA (AUROC: 0.876) cut-off was 12.3 mm2 (15.3 mm2 with highest PPV), while for NTR (AUROC: 0.858) it was 116.2% (146.0% with highest PPV). Conclusions: NTR can be simply and quickly calculated, and it can be used in anthropometric extremes.

Abstract
BackgroundPolymyalgia rheumatica (PMR) can be associated with giant cell arteritis (GCA), even in the absence of clinical suspicions of vasculitis. In addition, some studies have shown an association of PMR with the predominantly large vessel involvement.ObjectivesThe objective of our study was to assess the presence of subclinical GCA in patients with PMR and to compare its pattern of vascular involvement to patients with classical GCA.MethodsEight rheumatology European centers participated in the study. Cohort A represented consecutive newly diagnosed patients with PMR who fulfilled the 2012 EULAR/ACR Provisional Classification Criteria for Polymyalgia Rheumatica2 and had no symptoms or signs suggestive of GCA. Ultrasound (US) examination of four vessel territories (i.e. temporal, carotid, subclavian and axillary arteries) was performed bilaterally. Cohort B included all consecutive patients with the diagnosis of GCA evaluated on the fast-track clinic of one of the hospitals (HULP). The halo sign was considered as positive US finding for GCA3. In addition, intima-media thickness of arteries was measured, with a cut-off ≥0.34 mm for temporal arteries (TA) frontal and parietal, 0.42mm for common TA, and ≥1 mm for common carotid, axillary and subclavian arteries for positive result. The clinical characteristics of PMR patients were recorded and the frequency of subclinical GCA determined.ResultsCohort A included 41 PMR patients with subclinical GCA. Cohort B was formed by 97 GCA. The characteristics of the patients are shown in the Table 1. Figure 1 shows the different subtypes of vessel involvement in patients with PMR and subclinical GCA and in patients of the fast-track clinic with the diagnosis of GCA in a single hospital.Figure 1.Subtypes of vessel affectation in Subclinical GCA in PMR and in classical GCATable 1.Clinical characteristics of patients of Cohort A (Subclinical GCA in PMR n = 41/216) and B (GCA in the fast-track clinic n = 97)Cohort A (n = 41)Cohort B (n = 97)Sex female (%)17 (41.5%)53 (54.6%)Age (years) mean ± SD74±6.779 ± 12CRP mg/L49.6±49.146 ± 81.6Polymyalgia rheumatica41 (100%)47 (48.5%)Constitutional symptoms19 (35.18%)35 (36.1%)Subclinical PMR has a predilection for affectation of large vessels, followed by isolated cranial pattern (ie. Isolated temporal artery involvement) and by the mixed (cranial and extra-cranial) form. On the contrary, in classical GCA an isolated cranial involvement represents the more common pattern, followed by the mixed and finally isolated large vessel involvement.ConclusionSubclinical GCA in PMR shows a principal isolated extra-cranial involvement and with clearly different pattern than classical GCA.AcknowledgementsTo the GCA/PMR study groupDisclosure of InterestsNone declared

Abstract
BackgroundANCA-associated vasculitis (AAV) are small vessel vasculitis which may variously affect upper and lower respiratory tract. Patients with microscopic polyangiitis (MPA) and, less commonly, granulomatosis with polyangiitis (GPA), especially those who are ANCA-MPO-positive, may suffer from interstitial lung disease (ILD), which is associated with high morbidity and mortality as it is often underdiagnosed and responds poorly to conventional treatmentsObjectivesIn this study, we aimed to assess whether Krebs von den Lungen-6 (KL-6), a marker of fibrotic ILD, may be useful for distinguishing AAV patients with ILD from those without ILD, and whether its changes over time are correlated with disease activity.MethodsWe enrolled all consecutive patients evaluated in the period December 2020 - November 2021. Inclusion criteria were a diagnosis of GPA or MPA, active disease, and eligibility for Rituximab treatment according to EULAR recommendations. All patients underwent concomitant rheumatological and pneumological evaluation, lung function tests, routine blood tests, autoimmunity evaluation and KL-6 assay. Current and previous treatments, Birmingham vasculitis score (BVAS) and vasculitis damage index were also recorded.ResultsA total of 13 patients (Table 1) were enrolled. One was excluded due to a concomitant diagnosis of lung cancer. Higher serum KL-6 were in AAV-ILD compared with those without ILD (972.8±398.5 vs 305.4±93.9, p=0.0040). Area under the Receiver Operating Characteristics curve showed 100% of the diagnostic performance of KL-6 for identifying the ILD involvement (accuracy 91.7%) and the best cutoff value of 368 U/mL (Sensitivity 100% and specificity 87.5%). The decision-tree model showed a 33% improvement in class purity using a cut-off value of 513 U/mL to distinguish AAV patients with and without ILD (Figure 1). Stratifying AAV patients as MPA and GPA with and without ILD considering T0 and T1 KL-6, the model obtained an improvement of 40% for classifying GPA non-ILD with a T0 serum KL-6 cut-off value of 513 U/mL and a T1 KL-6 cut-off of 301 U/mL. A direct correlation was found between serum T0 KL-6 and T0 BVAS (r=0.578, p=0.044).Table 1.Patients’ featuresSex/ageDiagnosisLength of disease * (months)Organs involvedType of lung involvementT0 KL6 levelsT0 BVAST0 VDIT1 KL6 levelsT1 BVAST1 VDIF/83MPA28Lung, kidney, PNSILD, alveolar hemorrhage6258732507M/48GPA1Lung, kidney, nose, eyeNodules35218027920F/55GPA252Lung, skinNodules40115360233F/38MPA1Skin-34760---F/74MPA180Kidney, PNS-36811541405M/77MPA8Lung, kidney, PNS, skinILD, alveolar hemorrhage982241---F/49GPA60Nose, eye-1226211602M/60MPA40Skin, PNS-20591---F/39GPA4Nose-31063---M/71GPA24Lung, eye, jointsNodules, ILD152893---F/64MPA24LungILD7564-10030-F/59GPA72LungNodules3384--0-Figure 1.ROC curve and decision tree modelConclusionOur multicentre study demonstrated KL-6 as a reliable, non-invasive and easy-to-perform marker of ILD in AAV patients and its helpfulness for disease activity assessment.

Abstract
BackgroundNo clear-cut guidelines exist about the use of imaging procedures for the diagnosis of idiopathic inflammatory myopathies (IIM). Similarly, conflicting, and scanty data exist about Power Doppler Ultrasonography (PDUS) in this subset of patients. In this regard, we recently proposed (1) a 0-3 grey scale (GS) and Power Doppler (PD) score in a cohort of patients affected by IIM, evidencing a positive, statistically significant, correlation for PD and oedema and disease activity.ObjectivesThe aim of this study was to assess the diagnostic accuracy of our score in IIM patients compared to a control group.MethodsWe prospectively collected, since July 2020 to December 2021, all patients evaluated in Vasculitis and Myositis clinic, Rheumatology Unit, University of Siena, with a recent diagnosis of IIM, as well as patients with a previous, definite diagnosis of IIM and evaluated during follow-up or referred from other centres for a second opinion. As control group, we collected all patients affected by amyopathic dermatomyositis (DM) or who underwent myositis immunoblot or muscle biopsy for proximal limbs weakness but eventually received a diagnosis other than IIM. All patients underwent US examination of both thighs in axial and longitudinal scans.ResultsForty-five IIM patients (11 anti-synthetase syndrome, 20 DM, 12 PM, 2 scleromyositis) and twenty-six controls were included. During the observational period, 7, 8, 1 and 1 patients underwent PDUS twice, three, four and five times, respectivelyAssessing area under the receiver operating characteristic (AUROC) curve analysis, IIM patients and control group were distinguished according to PD sum, Oedema sum, atrophy sum and CRP values (Figure 1a). The best cut-off value for PD sum values was 0.5 (70.2% SE and 83.3% SP), for Oedema sum 1.5 (74.5% SE and 79.2% SP), atrophy sum 0.5 (63.4% SE and 65.4% SP) and CRP was 0.22 mg/dL (61.5% SE and 75% SP).Figure 1.Stratifying IIM population into two groups according to disease activity (PhGA≥2), AUROC curve analysis allow to distinguish these groups according to PD and oedema sum and CRP values (Figure 1b) and the best cut-off values was 1.5 (69.6% SE and 76.9% SP), 2.5 (52.2% SE and 92.3% SP) and 0.55 mg/dL (66.7% SE and 88.9% SP), respectively.Testing the IIM group versus control as dependent variable by logistic regression, with PD sum, oedema sum, atrophy sum, CRP, CPK and myoglobin as independent variables, the AUROC was 0.976. From the probability associated with the Chi-square tests, the Type II analysis showed the variable that most influences the IIM diagnosis was PD sum and oedema sum (p=0.017 and p=0.013, respectively) (Figure 1c).ConclusionGS and PDUS have proven an overall good diagnostic accuracy in distinguishing between IIM and myositis mimicker. In particular, even low values of PD (sum 1.5) display a good sensitivity and specificity and, together with oedema, elevated CRP values and myositis-specific and associated antibodies, may be considered a reliable tool for a definite diagnosis of IIM.References[1]Conticini E, Falsetti P, Al Khayyat SG et al.

Abstract
BackgroundDeregulated neutrophil extracellular traps (NET) formation is implicated in various diseases, including ANCA-associated vasculitis and pulmonary fibrosis (PF). Lung involvement is frequent in AAV, and interstitial lung diseases (ILD) are strongly related to MPO-ANCA positivity and mainly reported in microscopic polyangiitis. The association between AAV and ILD is a strong indicator of poor prognosis and limited survival. Neutrophils, ANCA and NET interplay in PF development in AAV.ObjectivesThis study aimed to review the literature concerning the implications of NET in lung fibrogenesis focused specifically on AAV associated with ILD, and the potential of NET as a theranostic marker.MethodsThrough scoping review methodology, we used a descriptive thematic analysis to understand the pathogenic role of NETs in patients with AAV and pulmonary fibrosis and their further role as a theranostic marker of this disease.ResultsQuality assessment of articles was evaluated through SANRA methodology (Table 1). The implications of NET in the pathogenesis of AAV and ILD (Figure 1), as well as an association between these two diseases, have been identified, but the underlying pathophysiological mechanisms are still unknown. Pharmacological or genetic inhibition of NET release reduces disease severity in multiple inflammatory disease models, indicating that NETs are potential therapeutic targets. In this regard, despite the lack of clinical data, we may hypothesize that an optimal management of AAV-ILD patients would require not only B-cells targeted therapy, but also NETs inhibition.Table 1.SANRA Score for quality assessmentN°.AuthorsJustification of the article’s importance for the readershipStatement of concrete aims or formulation of questionsDescription of the literature searchReferencingScientific ReasoningAppropriate presentation of dataTotal score1Pandolfi L et al. 202122012292Radermecker C et al. 202012022183Zhang S et al. 201921022184Skopelja-Gardner S et al. 201911012275Khawaja AA et al. 202022012186Chrysanthopoulou A et al. 201421022187Kraaij T et al. 201821021288Tang S et al. 201521012179Yoshida M et al. 2016120121710Nakazawa D et al. 2014210222911Hattanda F et al. 2019220121812Schreiber A et al. 2017220112813van Dam LS et al. 2019220111714Roitsch S et al. 2018120122815Takeuchi H et al. 20172202221016Su B et al. 2021210122817Söderberg D et al. 2015210121718Surmiak M et al. 20161201228Figure 1.The role of NET in interstitial lung disease associated with ANCA-associated vasculitisConclusionPreliminary findings seem to display a lack of efficacy of traditional immunosuppressants, such as Rituximab, in this subset of patients, while to date no patients suffering from a definite ILD was enrolled in clinical trials. Further insights would be provided by their employment, as a combination treatment, in the common clinical practice. Although we can imagine that inhibition of NETs in patients with AAV-ILD could reduce severity and mortality, we still lack a scientific basis that could improve our understanding of the disease from a molecular point of view.Disclosure of InterestsNone declared

Abstract
BackgroundPolymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are closely related diseases. PMR occurs in approximately 50 % of patients with GCA1; however the prevalence of subclinical GCA in PMR has not yet been widely studied.ObjectivesThe aim of our multicenter, prospective study was to determine the prevalence of subclinical GCA in newly diagnosed PMR, using vascular ultrasound (US) as a diagnostic tool.MethodsEight European centers participated in the study. The studied cohort represented consecutive newly diagnosed patients with PMR who fulfilled 2012 EULAR/ACR Provisional Classification Criteria for Polymyalgia Rheumatica2 without symptoms or signs suggestive for GCA. All patients underwent ultrasound (US) of both hips and shoulders, as well as of four bilateral arterial territories (i.e. temporal, common carotid, subclavian and axillary arteries). Patients with positive halo signs were considered to have subclinical GCA 3. An intima-media thickness ≥0.34 mm for frontal and parietal TA, 0.42mm for common TA, and ≥1 mm for common carotid, axillary and subclavian arteries for positive result. Clinical demographic and laboratory characteristics of the PMR pure group were compared with the PMR/GCA patient group.ResultsA total of 258 patients were included, 137 (53.1%) females with a mean age of 73±8.4 years. Table 1 shows the main differences in PMR patients with and without subclinical GCA. The only statistical significant difference between the two groups was the higher prevalence of morning stiffness > 40 minutes in the pure PMR group (p<0.05). A halo sign was found on at least one of the examined arteries in 56/258 patients (21.7%).The different subtypes of vessel involvement were available in 216 cases. Data compatible with the diagnosis of GCA was found in 41 cases (19%): 10 (24.3%) had only temporal artery involvement (“cranial” GCA), 27 (65.8%) had an extra-cranial artery involvement and 4 (9.8%) a mixed form with both cranial and extra-cranial artery involvement (Figure 1).Table 1.Clinical and demographic characteristicsFigure 1.Subtypes of subclinical GCA in PMR in 216 patients with cranial and extra-cranial examinationConclusionOne fifth of PMR patients without symptoms or signs of GCA have ultrasound findings consistent with the diagnosis of GCA. Subclinical GCA in PMR shows a predilection for extra-cranial artery involvement.References[1]Buttgereit F et al. JAMA. 2016;315:2442-58.[2]Dasgupta B et al.

Abstract
OBJECTIVES To investigate peripheral enthesitis with power Doppler ultrasound (PDUS) in patients presenting low back pain (LBP) and metabolic syndrome (MetS) in comparison with patients with only LBP, to correlate US scores with clinical-anthropometric characteristics, and to define any relationship between enthesitis and concurrent diffuse idiopathic hyperostosis syndrome (DISH). METHODS Sixty outpatients with LBP and MetS, evaluated with multi-site entheseal PDUS, scoring inflammatory and structural damage changes, were retrospectively analyzed. A group of 60 subjects with LBP, without MetS and evaluated with the same protocol, was analyzed as the control group. RESULTS Patients showed overweight (BMI 29.8) and low-grade inflammatory state (C-reactive protein [CRP] 0.58mg/dL, erythrosedimentation rate [ESR] 20.2mm/h). Enthesitis was demonstrated in 52 (86%) patients (17.6% entheses), and in 8 controls (13.3%) (p<.00001). PD signals (15% of patients) were associated with entheseal pain (p=.0138). US scores correlated with body mass index (BMI), pain, type 2 diabetes. In 28 (46%) patients a concurrent DISH was diagnosed, correlating with older age (p<.0001), CRP (p=.0428), ESR (p=.0069) and PDUS scores (p=.0312 inflammatory, p=.0071 structural). MetS had a strong association (OR 4.375, p=.0007) with concurrent DISH. CONCLUSIONS Diffuse peripheral enthesitis is very common in MetS. Almost half of MetS patients can have a concurrent diagnosis of DISH; they are older, with higher inflammation, and higher PDUS enthesitis scores.

Inflammatory muscle involvement in systemic vasculitis: A systematic review. Autoimmun Rev 2021; 21:103029.

Abstract
Vasculitis are severe systemic autoimmune diseases which may involve different organs and systems. Conversely, muscles do not represent an organ commonly involved by systemic vasculitis and myositis is not include among any classification or diagnostic criterion of vasculitis. In this regard, we aimed to review the literature in order to report all the available evidence concerning the inflammatory involvement of muscle in patients affected by systemic vasculitis. We collected a total of 108 papers, for a sum of 395 patients affected by muscle vasculitis. Most of them suffered from medium and small vessels vasculitis (mainly polyarteritis nodosa and ANCA-associated vasculitis) or from vasculitis secondary to rheumatoid arthritis. Conversely, muscle involvement in case of large vessel vasculitis occurred seldom, while only few papers reported such occurrence in Kawasaki or Behçet's disease. Histological findings may differ, but the most common ones displayed a necrotizing vasculitis of perimysium vessels, while granulomatous vasculitis was assessed only in case of ANCA-associated vasculitis patients. Creatine kinase were usually within normal range, seldom elevated, while imaging findings were generally undistinguishable from the ones found in idiopathic inflammatory myopathies: magnetic resonance imaging displays signal hyperintensity in T2 and STIR scans, while few data exist for positron emission tomography. The presentation of the disease may be fearsome and severe, sometimes life-threatening, but an overall good response to conventional immunosuppressants and/or glucocorticoids has been reported.

Abstract
Aim The aims of the study were to perform an ultrasound assessment of the dorsal portion of the scapholunate interosseous ligament and scapholunate joint space in patients with wrist complaints in a rheumatologic setting, to describe ultrasound abnormalities about scapholunate interosseous ligament region, and to correlate them with clinical data, presence of dorsal ganglion cysts and diagnoses of rheumatic diseases. Material and methods Seventy-four consecutive patients with wrist pain and/or swelling were evaluated by routine power Doppler ultrasound. Forty normal wrists were studied to confirm the normality values of the scapholunate joint. Results The mean width of the normal scapholunate joint was 2.49 mm (±0.49 SD), with a coefficient of variation on repeated measurements of 3.662%. The best predictors of scapholunate interosseous ligament degeneration were: older age (p <0.0001), male gender (p = 0.0049), and radiocarpal effusion (p = 0.0156). The presence of osteophytosis and calcifications of the scapholunate joint were higher (p <0.001) in rheumatic patients. Scapholunate calcifications showed a sensitivity of 98.2% and a specificity of 61.1% for calcium pyrophosphate deposition disease. Dorsal ganglion cysts were more frequent in younger subjects (p <0.0012) without rheumatic conditions (p <0.0001) or midcarpal synovitis (p <0.0001). Larger cysts often exhibited power Doppler signal (p <0.0001). The best predictors of scapholunate dissociation were: male gender (p = 0.0002), presence of midcarpal synovitis (p <0.0137), and higher grade of scapholunate interosseous ligament degeneration (p <0.0001). Scapholunate widening was greater (p = 0.0419) in calcium pyrophosphate deposition disease or rheumatoid arthritis than in other rheumatic conditions. Conclusions Ultrasound findings of scapholunate interosseous ligament degeneration and calcification, scapholunate space enlargement, and dorsal ganglion cysts should be considered in ultrasound reporting, since they add useful information about the diagnosis of associated rheumatic conditions.

Abstract
Background:Together with autoimmune-inflammation and fibrosis, microvasculopathy is a hallmark of SSc. However, also macrovascular changes may occur including peripheral proliferative vasculopathy. Whether this changes may represent a specific SSc marker with a predictive value remains a matter of debate.[1,2,3]Objectives:To study peripheral macrovascular involvement by color doppler ultrasound (CDUS) with spectral wave analysis (SWA) in a cohort of 40 SSc patients as compared to healthy controls. To further analyze any differences among the SSc population.Methods:Forty SSc patients and 36 healthy controls were examined by CDUS with SWA of both hands. Macrovascular involvement was assessed by measuring the resistivity index (RI) of distal ulnar and radial arteries. Examinations were performed with an Esaote MyLab Twice machine equipped with a linear 10-22 MHz probe. Ultrasound examination was carried out by two independent rheumatologists blinded to clinical conditions of the patients. Statistical analysis was performed by using MaxStat software.Results:The RI index resulted increased in the SSc cohort as compared with healthy controls (left ulnar RI 0.977 vs 0.715; right ulnar RI 0.996 vs 0.699; left radial RI 0.988 vs 0.706; right radial RI 0.999 vs 0.688; p<0.001). SSc patients with an increased RI in one artery were more probable to have an increased RI in the other vessels too (r 2 = 0.35; p<0.01). In addition, 8 out of 40 SSc patients presented left ulnar artery occlusion (UAO) and 7 out of 40 SSc patients presented right UAO, of which 6 presented bilateral UAO. Awaiting to enlarge the cohort for further analysis, descriptive data regarding increased RI at CDUS/SWA and clinical features, including years from onset of the disease, subtype of SSc, mRSS, history of digital ulcers, interstitial lung disease and PAH are described in Table 1.Conclusion:Peripheral macrovascular involvement was observed in SSc patients as compared with healthy controls. Further studies will determine whether this feature may have specificity for diagnosis/prognosis in SSc.References:[1]Lescoat A, Yelnik CM, Coiffier G et al.

Abstract
Background:No clear-cut guidelines exist about the use of diagnostic procedures for idiopathic inflammatory myopathies (IIM) and only scanty and conflicting data report the use of ultrasound (US).Objectives:We aimed to assess if grey-scale (GS) and Power Doppler (PD) US, graded with a 0-3-points-scale, may be a reliable tool in a cohort of patients affected by IIM.Methods:We prospectively collected, since July to October 2020, all patients referred to Vasculitis and Myositis clinic, Rheumatology Unit, University of Siena, for suspected IIM, as well as patients with a previous, definite diagnosis of IIM and evaluated during follow-up or referred from other centers for a second opinion. All patients underwent US examination of both thighs in axial and longitudinal scans. Edema and atrophy, both assessed in GS, and PD, were graded with a 0-3-points-scale. Spearman test was used to identify the correlations between US and clinical and serological variables.Results:A total of 18 patients was included. Four of them were evaluated twice, at baseline and within 3 months of therapy. Muscle edema was found to be directly correlated with physician global assessment (PhGA), serum myoglobin and PD and negatively with disease duration. PD score was positively correlated to PhGA and negatively to disease duration. Muscle atrophy directly correlated with Myositis Damage Index and patients’ age. The single-thigh sub-analysis evidenced a direct correlation between PD score and Manual Muscle Test.Conclusion:In our cohort, we found that edema and PD are strictly related to early, active myositis, suggesting that an inflamed muscle should appear swollen, thickened and with Doppler signal. Conversely, muscle atrophy reflects the age of the patient and the overall severity of the disease. Such findings shed a new, promising, light in the role of US in diagnosis and monitoring of IIMs.Table 1.Siena Myositis Ultrasound Grading Scale (SMUGS).Grey-scale edemaGrey-scale atrophyPower Doppler0Normal muscle echotexture with hyperechoic septa and hypoechoic muscle fibers, conserved thickness.Normal muscle echotexture, with hyperechoic septa and hypoechoic muscle fibers, conserved thickness.No PD signal.1Focal hypoechoic areas, where septa are less evident.

Abstract
Background:Sacroiliac joints (SIJs) involvement is a characteristic feature of Spondylarthritis (SpA). Magnetic resonance imaging (MRI) has been included in the new Assessment of SpA International Society (ASAS) criteria for the classification of non-radiographic axial SpA. Power Doppler ultrasound (PDUS) and spectral Doppler US have been used in few works, also from our group, to evaluate the inflammatory activity of the SIJs, in comparison with MRI, with different results.Objectives:We aimed to evaluate the value of PDUS with spectral wave analysis (SWA) in the assessment of suspected active sacroiliitis (SI). PDUS of SIJs was used as a screening tool alongside the routine PDUS assessment of peripheral joints.Methods:143 patients (114 females and 29 males, mean age 46,2 years, mean BMI 25.9) with new onset of inflammatory back pain (IBP), were included. Peripheral symptoms were allowed. Every patient underwent a PDUS examination of SIJs as previously reported. The sonographer was blinded to the clinical data. An Esaote Twice US machine, with convex 1-8 MHz and linear 6-18 MHz probes, was used, with standardized parameters. PD signals detected in the SIJs, were scored with a 3-points scale: 0= absence of signals, 1= isolate vessels, 2= more than one vessel. The signals were also classified as intra-articular (vascularity from deep joint and inter-osseous ligament) or peri-articular (vascularity along posterior sacroiliac ligament). SWA was applied to the same vessels calculating the Resistive Index (RI) (Figure 1). A PDUS diagnosis of active SI was made with a grade 1 of vascularity and RI<0,60, or grade 2 of vascularity and RI<0,70. PDUS multi-site examination of peripheral joints and entheses was also performed; entheseal involvement was scored with Belgrade Ultrasound Enthesitis Score (BUSES) and as global enthesitic charge (GEC). Every patient underwent MRI of SIJs within 2 weeks, and before to start pharmacologic treatment. The non-parametric Spearman rank test and univariate linear regression analysis was applied using InStat GraphPad statistical package.Results:A time of 5-8 minutes was sufficient to set and to complete PDUS/SWA examination on both SJJs. All patients considered this examination quick, not painful and substantially comfortable. PD signals were detected in 124 patients (mean RI 0,56). Bone marrow edema (BME) lesions (active SI on MRI) were detected in 94 patients. A final diagnosis of SpA was made in 103 patients (81 females, 22 males). Among SpA patients 24 had psoriasis, 3 inflammatory bowel disease, 3 uveitis, 5 were B27+, and they had mean BUSES of 4,1 and GEC of 1,2. The mean SIJs PDUS score was 1,3 in SpA and 0,52 in not-SpA patients. The mean SIJs RI was 0,53 in SpA and 0,68 in not-SpA patients. A significant correlation was demonstrated between MRI and PDUS diagnosis of SI (r=0,6486, p<0,0001), between MRI diagnosis and PD grading (r=0,4937, p<0,0001). The split analysis of peculiar parameters of imaging between the two methods also showed significant correlation: periarticular vascularity showed correlation with post-contrast MRI evidence of posterior capsulitis and enthesitis (p=0,001), as SIJs BME correlated with intra-articular PD signals (p<0,001). RI from SWA analysis was inversely correlated with MRI diagnosis of active SI (p<0.0001). SIJs PD demonstrated a significant correlation with SIJs pain (p<0,001), but not with inflammatory reactants, GEC, peripheral synovitis, and a weak correlation with BUSES (p=0,038).Conclusion:SIJs PDUS/SWA may be an optional method for preliminary screening of active SI, as a feasible, cheap and an accurate diagnostic tool, compared with MRI as a gold standard for nr-Axial SpA. PD US in SI. Right SI joint with a PD signal within inter-osseous ligament (curved arrow), where spectral PD analysis shows a RI of 0,62.

Abstract
Background:Baricitinib, an oral Janus kinase (JAK) 1-2 inhibitor, is currently used among biologic DMARDs (bDMARDs) after the failure of methotrexate (MTX) in rheumatoid arthritis (RA). Power Doppler ultrasound (PDUS) is a promising, non-invasive imaging method to assess synovitis in RA: results from numerous studies suggest that it provides additional information to clinical and conventional radiographic examinations.Objectives:The main objective of our study was to evaluate short-term efficacy of Baricitinib in reducing synovitis, using the composite semi quantitative scale (0–3 grades) PDUS synovitis score, developed by the Outcome Measures in Rheumatology– European League Against Rheumatism (OMERACT– EULAR)-Ultrasound Task Force. Moreover both synovial hyperplasia and intrasynovial power Doppler (PD) signal were also scored as single components/parameters on 0-3 scales. Secondary objective was to assess the concordance between patient reported outcomes (PROs), markers of inflammation, physical examination and US.Methods:We enrolled 30 patients fulfilling 2010 ACR and EULAR criteria for RA. All patients had failed at least one anti-TNF. Each patient was prescribed Baricitinib 4 mg/daily at T0, in addition to MTX and/or oral steroids at a dosage ≤ 7, 5 mg/day of Prednisone or equivalent, at T’. All patients were evaluated at baseline (T0) and then after one month (T1), 3 months (T2) and 6 months (T3) of treatment. Swollen and tender joints (out of 28)were evaluated and recorded, as well as patient (PGA) and physician global assessment (PhGA) and pain, expressed in a visual analog scale (VAS). Disease activity was evaluated at each visit using DAS28 (Disease activity score 28), CDAI (Clinical disease activity index)and SDAI(Simplified disease activity index), accompanied by a complete blood count, Erythrocyte sedimentation rate (ESR) and C- reactive protein (CRP) collection. Statistical analysis was performed using GraphPad version 9.0.0. PDUS examination, was carried out by two rheumatologists (PF and CB) blinded to clinical conditions of the patients, using an Esaote Mylab Twice (Genoa, Italy), equipped with a high-frequency (6-18 MHz) linear probe. With standardised Doppler parameters (pulse repetition frequency between 500-750 Hz; Doppler frequency between 7–11.1 MHz). PDUS was performed at each visit bilaterally for 22 joint sites [MCPs 1–5, proximal interphalangeal joints (PIPs) 1–5, wrist, elbow, glenohumeral, knee, tibiotalar, talonavicular and calcaneocuboidal and metatarsophalangeal joints (MTPs) 1–5] for a total of 44 joints for each patient.Results:we observed a reduction of VAS pain (T0 vs, T6<0,0001) PDUS composite score (T0 vs. T6 p<0,0001), Power Doppler (T0 vs. T6 p<0,0001) synovial hyperplasia (T0 vs. T6 p=0,0002), CRP (T0 vs. T6 p<0,0001) and ESR (T0 vs. T6 p <0,0001) was observed in our patients. Accordingly, DAS-28, CDAI and SDAI displayed a significant reduction too (DAS-28: T0 vs. T6 p< 0, 0001; CDAI: T0 vs. T6 p< <0, 0001; SDAI: T0 vs. T6 p= 0, 0003).Conclusion:We investigated the efficacy of Baricitinib in real life, evaluating both from a clinimetric and ultrasound point of view. Baricitinib, demonstrated a significant parallel and fast improvement in VAS, PDUS and CRP was found at follow up assessment as early as one month of therapy. In conclusion, these results demonstrated the short term efficacy of Baricitinib 4mg for up to 6 months and providing a prompt improvement of PROs within the first weeks of treatment.Figure 1.The difference between the means of PD and of the VAS pain over time (T0, T1, T3 and T6).

Abstract
OBJECTIVES No clear-cut guidelines exist about the use of diagnostic procedures for idiopathic inflammatory myopathies (IIM) and only scanty and conflicting data report the use of ultrasound (US). In this regard, we aimed to assess if grey-scale (GS) and Power Doppler (PD) US, graded with a 0-3-points-scale, may be a reliable tool in a cohort of patients affected by IIM. METHODS All patients underwent US examination of both thighs in axial and longitudinal scans. Edema and atrophy, both assessed in GS, and PD, were graded with a 0-3-points-scale. Spearman test was used to identify the correlations between US and clinical and serological variables. RESULTS A total of 20 patients was included. Six and 2 of them were evaluated twice and 3 times, respectively. Muscle edema was found to be directly correlated with physician global assessment (PhGA), serum myoglobin and PD and negatively with disease duration. PD score was positively correlated to PhGA and negatively to disease duration. Muscle atrophy directly correlated with Myositis Damage Index, disease duration and patients' age. The single-thigh sub-analysis evidenced a direct correlation between PD score and Manual Muscle Test. CONCLUSIONS In our cohort, we found that edema and PD are strictly related to early, active myositis, suggesting that an inflamed muscle should appear swollen, thickened and with Doppler signal. Conversely, muscle atrophy reflects the age of the patient and the overall severity of the disease. Such findings shed a new, promising, light in the role of US in diagnosis and monitoring of IIMs.

Abstract
OBJECTIVES The objectives of this study were to study with Power Doppler US (PDUS) the SI joints (SIJs) of patients with suspected active sacroiliitis, to describe SIJ flows with spectral wave analysis (SWA) on Doppler US, and to correlate US data with both clinical characteristics and presence of SIJ bone marrow oedema (BME) in subsequent MRI. METHODS A total of 42 patients (32 females and 10 males, mean age 46.8 years) with recent onset of inflammatory back pain (IBP) were included. Every patient underwent US examination with a convex 1-8 MHz probe [scoring PDUS signals with a three-point scale and describing flows in SWA calculating the mean Resistive Index (RI)] and subsequent MRI of the SIJs. RESULTS PDUS signals were detected in 34 patients and 62 SIJs. In 29 patients and 56 SIJs, MRI revealed BME. A definite diagnosis of SpA was made in 32 patients. PDUS signals were more frequent (P < 0.0001) in patients with a final diagnosis of SpA, yielding a higher PDUS score (P = 0.0304). PDUS grading correlated with both BME grading (r = 0.740, P = 0.0001) and AS DAS (ASDAS) (r = 0.6257, P = 0.0004), but not with inflammatory reactants nor anthropometric data. Mean RI were, respectively, 0.60 and 0.73 (P < 0.0001) in patients with or without diagnosis of active sacroiliitis. The most inclusive RI cut-off resulted <0.70 [positive predictive value (PPV) 94%, accuracy 90%, P = 0.0001]. The best Likelihood Ratio (5.471) for RI to detect pathologic cases was obtained with a cut-off of <0.60 (PPV 96%). CONCLUSIONS PDUS and SWA of SIJs demonstrate good diagnostic accuracy for active sacroiliitis compared with MRI.

Diffuse Peripheral Enthesitis in Metabolic Syndrome: A Retrospective Clinical and Power Doppler Ultrasound Study. REUMATOLOGIA CLINICA 2021; 18:S1699-258X(21)00032-2. [PMID: 33640321 DOI: 10.1016/j.reuma.2020.12.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 12/23/2020] [Accepted: 12/30/2020] [Indexed: 12/13/2022]
Abstract
OBJECTIVES To investigate peripheral enthesitis with power Doppler ultrasound (PDUS) in patients presenting low back pain (LBP) and metabolic syndrome (MetS) in comparison with patients with only LBP, to correlate US scores with clinical-anthropometric characteristics, and to define any relationship between enthesitis and concurrent diffuse idiopathic hyperostosis syndrome (DISH). METHODS Sixty outpatients with LBP and MetS, evaluated with multi-site entheseal PDUS, scoring inflammatory and structural damage changes, were retrospectively analyzed. A group of 60 subjects with LBP, without MetS and evaluated with the same protocol, was analyzed as the control group. RESULTS Patients showed overweight (BMI 29.8) and low-grade inflammatory state (C-reactive protein [CRP] 0.58mg/dL, erythrosedimentation rate [ESR] 20.2mm/h). Enthesitis was demonstrated in 52 (86%) patients (17.6% entheses), and in 8 controls (13.3%) (p<.00001). PD signals (15% of patients) were associated with entheseal pain (p=.0138). US scores correlated with body mass index (BMI), pain, type 2 diabetes. In 28 (46%) patients a concurrent DISH was diagnosed, correlating with older age (p<.0001), CRP (p=.0428), ESR (p=.0069) and PDUS scores (p=.0312 inflammatory, p=.0071 structural). MetS had a strong association (OR 4.375, p=.0007) with concurrent DISH. CONCLUSIONS Diffuse peripheral enthesitis is very common in MetS. Almost half of MetS patients can have a concurrent diagnosis of DISH; they are older, with higher inflammation, and higher PDUS enthesitis scores.

Abstract
Polyarteritis nodosa (PAN) is a medium vessels vasculitis variously involving different organs and systems, sometimes with an aggressive course, leading to death or disability in a significant number of cases. First-line treatment usually relies on steroids and classical immunosuppressants, but a growing number of case reports and small case series shows the potential role of biologic drugs, mostly anti-tumor necrosis factor (TNF)-α agents, in inducing and maintaining remission in patients affected by PAN. Similarly, the recently described autoinflammatory disease named deficit of adenosine deaminase 2 (DADA2), considered by several experts as a more precocious and aggressive variant of PAN, seems to respond to a prompt treatment with TNF-α inhibitors. The aim of this review is to collect all existing evidences about the use of biologic drugs in PAN and DADA2. Fifty-one articles published during the last 15 years were retrieved, including 58 and 76 patients affected by PAN and DADA2, respectively, and treated with biologic drugs. The majority of subjects was treated with TNF-α inhibitors, whose effectiveness was reported in the treatment of such difficult-to-manage diseases, particularly in DADA2. Among the other biologic drugs, Tocilizumab was successfully employed in some subjects affected by PAN who did not respond to TNF-α inhibitors, while Rituximab did not give substantial benefits neither in PAN nor in DADA2. Only few data exist about the role of Janus-kinase inhibitors and anti-IL1 agents. This study provides the first comprehensive assessment of biologic agents in both PAN and DADA2, with encouraging results especially in the context of TNF-α inhibitors. Nevertheless, due to the lack of prospective, randomized, case control studies, further efforts should be made in order to fully elucidate the role of these drugs in such rare and life-threatening conditions.

Abstract
Background:Polymyalgia rheumatica (PMR) is the most common inflammatory disorder of elderly; an association with environmental triggers and deregulated immune response has been described.Objectives:The aim of this study was to investigate the presence of environmental triggers before the onset of PMR and its association to a particular subset of disease.Methods:The database of 58 consecutive PMR patients recruited from a single rheumatology secondary care setting was retrospectively analyzed to investigate the frequency of environmental triggers and correlations with clinical characteristics. Patients underwent multidistrict ultrasound examination of both proximal and distal sites. Laboratory tests were repeated after one month from first visit, when steroids were started, and about every three months during follow-up (for at least 24 months)Results:Fifteen PMR patients (26%) described a connection with environmental agents: six PMR patients reported a vaccination, 3 an upper respiratory tract infection and 1 pneumonia before the onset of disease. Five patients reported seasonal influenza as trigger of PMR. The model of multivariate linear regression which better predicted a shorter time to normalize inflammatory reactants (R squared 27,46%, p=0,0042) comprised the presence of an environmental trigger and a higher CRP. A linear regression analysis confirmed an inverse correlation between CRP at onset ant time to normalize inflammatory reactant (r= -0,3031, p=0,0208). A significant correlation was demonstrated between presence of environmental trigger and shorter time to normalize inflammation (r=-0,5215, p<0,0001), lesser frequency of gleno-humeral synovitis on US (r=-0,3774, p=0,0038).Conclusion:Our work describes a correlation between environmental triggers in PMR and higher CRP at diagnosis and faster response to therapy. We may suppose that these patients belong to a more specific subtype of PMR, in whom external stimuli, such as vaccinations or infections, may lead to a deregulated response within the context of an impaired immune and endocrine system. We recommend a systematic research of previous infections or vaccination in recent onset PMRDisclosure of Interests:None declared

Abstract
Background:Metabolic syndrome (MS) is a clinical condition characterized by central obesity and additional factors such dyslipidemia, hypertension, raised fasting plasma. Scanty observations describe the association of MS with musculoskeletal conditions, such as enthesopathies and diffuse idiopathic hyperostosis syndrome (DISH). Musculoskeletal ultrasound (US) has been applied to the study of entheses, but the real prevalence and characteristics of entheseal involvement in MS has yet to be clarified.Objectives:The aim of our work was to study the US-defined entheseal changes in MS, to correlates the US enthesitis scores to clinical characteristics, and to define a relation between MS-related enthesitis and the presence of concurrent DISHMethods:Sixty consecutive outpatients (24 males, 36 females, mean age 60 years), all fullfilling International Diabetes Foundation (IDF) criteria for MS, were also evaluated with multi-site bilateral US entheseal examination. Each patient underwent power Doppler (PD) US examination of twelve entheseal sites, using Esaote MyLab Twice with 6–18 MHz transducer. Enthesitis was defined on the basis of OMERACT’s filter. Inflammatory and structural changes were scored as a whole when present (score 1) or absent (score 0). The sum of entheses with inflammatory and structural damage was defined as “global inflammatory score” (GIs) and “global structural damage score” (GSDs) for each patient. The Leeds Enthesitis Index (LEI) was also applied, and a spinal radiography was obtained for each patient to research concurrent signs of DISH satisfying Resnick and Niwayama criteria.Results:Patients showed moderate overweight (mean BMI 29) and a diagnosis of type 2 diabetes was present in 24 (40%). A low-grade inflammatory state was demonstrated in MS (mean CRP 0,58 md/dL, mean ESR 21,9 mm/h). A high prevalence of US-defined enthesitis was noted in 52 patients (86%) and 127/720 entheses (17,6%). PD signals, were reported in 11 patients (18%) and 11/720 entheses (1,52%), and they were associated to clinical symptoms expressed as LEI (p=0,0138). Erosions, although rare (0.3% of entheses), were more frequent in males (p= 0.001). Moreover, in 57 patients (95%) and 217 entheses (30%) structural damages were found. A correlation was found between GIs and GSDs and both BMI (p=0.0233 and p=0.0068 respectively), LEI (p=0.03 and p=0.0099 respectively), and type 2 diabetes (p=0.0248 and p=0.0156 respectively). In 28 patients (46%) a concurrent diagnosis of DISH was made. In multivariate regression analysis the best predictors for DISH were higher levels of CRP (p=0,038) and older age (p<0,0001). DISH correlated with older age (p<0,0001), CRP and ESR (p= 0,0428 p=0,0069 respectively) and US global scores for enthesitis (p=0,0312 for GIs, p=0,0071 for GSDs).Conclusion:This is the first study where diffuse enthesitis and entheseal structural damage are demonstrated with high prevalences in MS, comparable or also higher than those reported for SpA-related enthesitis. Our data, obtained using the most recent OMERACT’s definition for US-detected enthesitis (proposed for SpA), also suggest a low specificity of this definition, in consideration of the high prevalence of MS-associated enthesitis. Moreover PD was associated to entheseal pain expressed as LEI. Both GIs and GSDs showed a correlation with overweight and type 2 diabetes. As secondary result, this study demonstrated that almost half of patients with MS could have a concurrent diagnosis of DISH. Patients with DISH were older, with higher levels of inflammation, and higher scores of US-defined enthesitis. Our results suggest that MS and DISH could be strictly related; diffuse enthesitis with a low-grade inflammatory state should be regarded as potential factor of progression from MS towards a conclamed DISH.Disclosure of Interests:None declared

Abstract
Background:SIJ involvement is a characteristic feature of Spondylarthritis (SpA). Magnetic Resonance imaging (MRI) has been included in the new Assessment of SpA International Society (ASAS) criteria for the classification of Axial SpA. Gray scale US, Color Doppler ultrasound (CDUS), contrast-enhanced CDUS, and spectral Doppler (SD) US has been used in few works to evaluate the inflammatory activity of the SIJ with not conclusive results. Power Doppler ultrasound (PDUS) was not yet applied to the study of SIJ with active SI.Objectives:The aim of this work was to study with PDUS and SD US the SIJ of patients with suspected active SI, to describe inflammatory flows with spectral wave analysis (SWA) in duplex Doppler US, and to correlate US data with clinical characteristics and the presence of bone marrow edema (BME) in MRI.Methods:22 patients (18 females and 4 males, mean age 35 years) with new onset of inflammatory back pain (IBP), were included. Every patient underwent an US examination in prone position. The sonographers were blinded to the clinical data of the patient. A Esaote Twice US machine, equipped with a convex multifrequency 1-8 MHz probe, was used, with standardized parameters: 1-5 MHz for gray scale, 1.9-2.3 MHz frequency for Doppler with Pulse Repetition Frequency (PRF) of 1.0 KHz and a color gain just under the artifact limit. SIJ was located as the hypoechoic triangle delimited between the sacrum and iliac bone, and the posterior SI ligament as the upper margin. The first sacral foramen was always localized to avoid measurement of the normal pre-sacral arteries. The PDUS was applied, and if any signals were detected in the SIJ, they were scored with a 3-points scale: 0= absence of signals, 1= isolate vessels, 2= more than one vessel. The signals were also classified as intra-articular or peri-articular. The same vessels were also evaluated using quantitative SD calculating the Resistive Index (RI=peak of systolic flow- end diastolic flow/peak systolic flow), ranging between 0 and 1. Every patient underwent MRI of SIJ within the same week, before treatment. A statistical analysis was performed, estimating the sensitivity and specificity against the gold standard (presence of BME in the same SIJ according to ASAS criteria). The Spearman rank not-parametric test was applied to correlate the presence and grading of BME with PDUS grading and RI. A regression analysis was applied between PDUS results and clinical characteristics.Results:In 14/22 SIJ MRI revealed BME. In 13 of them, PDUS confirmed abnormal hypervascularisation in the intrarticular portion of SI, and in 3 in the periarticular site too. Two SIJ showed hypervascularisation at PD with no BME in MRI. A significant correlation was demonstrated between positivity and grading of PD and presence of BME in MRI (p=0.0005). SD analysis demonstrated low Resistance Index (RI) values in 14 SIJ (mean 0.57). An inverse correlation was demonstrated between RI and grading of BME in MRI (r= -0,6229, p= 0,044). The diagnostic accuracy of SD for detection of active SI varied on the basis of RI cut-off value. The best values of sensitivity (62,5%) and specificity (61,5%) were obtained with a RI cut-off values of 0.60. A multiple regression model demonstrated a significant relationship between PDUS signals and ASDAS (p=0.0382), but not with inflammatory reactants.Conclusion:PDUS and SD US of SIJ can be useful as first imaging assessment in suspected active SI, demonstrating a good diagnostic accuracy compared with MRI. Intra-articular low RI values (<0.60) on SD indicate active SI with good accuracy. Moreover, PDUS signals into the SIJ correlate with clinical symptoms but not with inflammation reactants.Figure 1.Doppler US in SI.Right SIJ with a Doppler signal along the posterior SIJ ligament, and another Doppler signal into the joint, where SD analysis gave a RI of 0,62.Disclosure of Interests:None declared
