ABSTRACT

OBJECTIVE: To define a semiquantitative classification of finger pulp blood flow (FPBF) and to evaluate whether this classification could be used to assess FPBF in healthy controls and in systemic sclerosis (SSc) patients. METHODS: Thirty controls and 86 SSc patients were consecutively included. A classification of FPBF including 5 grades (from grade 0 [no signal] to 4 [signal detected on the entire finger pulp, including the subepidermal vascular network]) was evaluated. This classification was explored in basal conditions and after hand baths in hot and cold water in controls. Its relevance was also assessed at room temperature in SSc patients. RESULTS: In controls, power Doppler ultrasonography (PDUS) of FPBF was improved after hot challenge (P = 0.024), whereas cold challenge decreased FPBF (P = 0.001). FPBF correlated with the vasodilation status assessed by the resistivity index of radial arteries (Spearman's correlation coefficient = -0.50, P = 0.0049). Grade 0 was more frequent in SSc patients than in controls (22.1% versus 3.3%; P < 0.05). In SSc patients, grade 0 was associated with severity markers of the digital vasculopathy such as digital ulcers (DUs) (current or past) (P < 0.05) or ulnar artery occlusion (P < 0.05). On the other hand, DUs were less frequent in patients with grade 4 (P < 0.05). A pathologic threshold of <2 (grade 0 or 1) was significantly associated with DUs (odds ratio 6.67 [95% confidence interval 2.31-19.21], P < 0.0001). CONCLUSION: PDUS allowed a semiquantitative evaluation of FBPF in SSc patients and controls. Further studies are warranted to validate these results in independent SSc populations and to compare PDUS to existing tools assessing digital blood flow.

ABSTRACT

The performance of a pair of blood culture vials (BACTEC® Plus Aerobic/F, and Anaerobic Lytic/F) were analyzed in 496 osteoarticular specimens (246 synovial fluids and 250 crushed bone samples), obtained in patients during routine diagnostic procedure at the Teaching Hospital of Rennes (France). The positive detection times were recorded for a 14 day-incubation period, and compared between both vials and with agar cultures. For samples from infected patients, the positive detection time was significantly shortened when vials were used compared to agar plates (p < 0.001). Median positive detection time was later with the Anaerobic Lytic/F vials (15.0 h) compared to the Plus Aerobic/F (13.0 h). Positivity rate was similar for Anaerobic Lytic/F vials (80.4%) and Plus Aerobic/F vials (83.2%) (p = 0.25). Some microorganisms were only identified from aerobic vials (15.5%) or from anaerobic vials (12.7%). The use of both atmosphere conditions for optimal positive detection time is therefore critical.

ABSTRACT

To characterize Lyme arthritis, with a focus on management, and outcome. Observational retrospective multicentre study in Western France, of all consecutive cases of Lyme arthritis, documented by Borrelia burgdorferi IgG on ELISA serological testing, confirmed by Western blot, with or without positive Borrelia PCR in synovial fluid, with no alternative diagnosis. We enrolled 52 patients (29 males), with a mean age of 43 ± 19.4 years. Most patients had monoarthritis (n = 43, 82.7%), involving the knee (n = 51, 98.1%), with a median delay between symptoms onset and Lyme arthritis diagnosis of 5 months (interquartile range, 1.5-8). Synovial fluid analysis yielded median white cell count of 16,000/mm3 (9230-40,500), and positive PCR in 16 cases (39%), for B. burgdorferi sensu stricto (n = 5), B. garinii (n = 5), B. afzelii (n = 3), and undetermined (n = 3). All patients received antibiotics, for a median duration of 28 days (21-30), with doxycycline (n = 44, 84.6%), ceftriaxone (n = 6, 11.5%), or amoxicillin (n = 2). Twelve patients (23.1%) also received intra-articular injection of glucocorticoids as first-line treatment. Of 47 patients with follow-up, 35 (74.5%) had complete resolution of Lyme arthritis. Lyme arthritis in Western Europe may be due to B. burgdorferi ss, B. afzelii, or B. garinii. Clinical presentation is similar to Lyme arthritis in North America (i.e. chronic knee monoarthritis), with low sensitivity of synovial fluid PCR (39%).

ABSTRACT

OBJECTIVE: To evaluate the diagnostic performance of ultrasound examination of the salivary glands (US-SG) according to the 2019 Outcome Measures in Rheumatology (OMERACT) US scoring system for Sjögren's syndrome (SS). METHODS: The present work was a retrospective study based on a multicentric cohort with SS/sicca syndrome. The American College of Rheumatology (ACR)/European Alliance of Associations for Rheumatology (EULAR) 2016 classification criteria for SS (a score of ≥4 without ocular staining score), the American-European Consensus Group (AECG) 2002 classification criteria, and clinician experts were considered as reference standards for diagnosis of SS. An OMERACT score of ≥2 according to 2 independent readers defined the diagnosis of SS based on US-SG assessment. Diagnostic performances and interobserver reproducibility of US-SG were assessed. RESULTS: Forty-two patients fulfilling the ACR/EULAR 2016 criteria for SS were compared to 30 control subjects with sicca syndrome. Twenty-five patients were diagnosed as having SS according to US-SG evaluation, and they were more frequently observed in the SS group (52.5%) than in the control group (10.0%) (P < 0.001). US-SG showed an area under the curve (AUC) of 0.751 (95% confidence interval [95% CI] 0.621, 0.882) for the diagnosis of SS (ACR/EULAR 2016 classification). The inclusion of US-SG in the ACR/EULAR 2016 classification improved sensitivity (91.5% versus 89.4%) with limited decrease of specificity (96.0% versus 100%) and with an AUC of 0.975 (95% CI 0.945, 1.00). Similar results were observed when US-SG was included in the AECG 2002 classification criteria. Interobserver reproducibility of a score of ≥2 according to the 2019 OMERACT US scoring system for SS diagnosis was good (κ = 0.73 [95% CI 0.64, 0.81]). Histologic lymphocyte infiltration of the minor salivary glands was associated with the OMERACT grading of US-SG. CONCLUSION: The present study confirms the good specificity of the 2019 OMERACT US classification measures of US-SG for the diagnosis of SS and its feasibility in daily practice.

ABSTRACT

Whipple disease (WD) is a rare infectious systemic disease. Rheumatologists are at the frontline of WD diagnosis due to the early rheumatological manifestations. An early diagnosis is crucial, as usual anti-rheumatic drugs, especially TNF inhibitors, may worsen the disease course. We conducted a retrospective multicentre national study from January 2010 to April 2020 to better characterize the rheumatological features of WD. Classic WD (CWD) was defined by positive periodic acid-Schiff (PAS) staining of a small-bowel biopsy sample, and non-CWD (NCWD) was defined by negative PAS staining of a small-bowel biopsy sample but at least one positive Tropheryma whipplei (TW) polymerase chain reaction (PCR) for a digestive or extradigestive specimen. Sixty-eight patients were enrolled, including 11 CWD patients. Twenty patients (30%) received TNF inhibitors during the WD course, with inefficacy or symptom worsening. More digestive symptoms and systemic biological features were observed in CWD patients than in NCWD patients, but both patient groups had similar outcomes, especially concerning the response to antibiotics and relapse rate. Stool and saliva TW PCR sensitivity were both 100% for CWD and 75% for NCWD and 89% and 60% for small-bowel biopsy sample PCR, respectively. WD encountered in rheumatology units has many presentations, which might result from different pathophysiologies that are dependent on host immunity. Given the heterogeneous presentations and the presence of chronic carriage, multiple TW PCR tests on samples from specific rheumatological sites when possible should be performed, but samples from nonspecific digestive and extradigestive sites also have great value.

ABSTRACT

BACKGROUND: Calcific tendinitis of the rotator cuff is a frequent cause of shoulder pain. Ultrasound-guided percutaneous lavage (UGPL) is an effective treatment, but factors associated with good clinical and radiological outcomes still need to be identified. PURPOSE: To study the clinical, procedural, and radiological characteristics associated with improved shoulder function and the disappearance of calcification on radiograph after UGPL. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: This is a post hoc analysis of the CALCECHO trial, a double-blinded randomized controlled trial conducted on 132 patients. The trial assessed the effect of corticosteroid injections after UGPL, and patients were randomly assigned to receive either corticosteroid or saline solution in the subacromial bursa. We analyzed all patients included in the randomized controlled trial as 1 cohort. We collected the patients' clinical, procedural, and radiological characteristics at baseline and during follow-up (3, 6, and 12 months). Univariable analysis, followed by multivariable stepwise regression through forward elimination, was performed to identify the factors associated with clinical success (Disabilities of the Arm, Shoulder and Hand [DASH] score <15) or the disappearance of calcification. RESULTS: Good clinical outcomes at 3 months were associated with steroid injections after the procedure (odd ratio [OR], 3.143; 95% CI, 1.105-8.94). At 6 months, good clinical evolution was associated with a lower DASH score at 3 months (OR, 0.92; 95% CI, 0.890-0.956) and calcium extraction (OR, 10.7; 95% CI, 1.791-63.927). A lower DASH at 6 months was also associated with a long-term favorable outcome at 12 months (OR, 0.939; 95% CI, 0.912-0.966). Disappearance of calcification at 3 and 12 months occurred more frequently in patients in whom communication was created between the calcification and the subacromial bursa during the procedure (OR, 2.728 [95% CI, 1.194-6.234] at 3 months; OR, 9.835 [95% CI, 1.977-48.931] at 12 months). Importantly, an association between calcification resorption and good clinical outcome was found at each time point. CONCLUSION: Assessing patients at 3 months seems to be an essential part of their management strategy. Calcium extraction and creating a communication between the calcific deposits and subacromial bursa are procedural characteristics associated with good clinical and radiological evolution.

ABSTRACT

OBJECTIVES: The aim of this study was to show the usefulness of a mid-infrared fibre evanescent wave spectroscopy point of care device in the identification of septic arthritis patients in a multicentre cohort, and to apply this technology to clinical practice among physicians. METHODS: SF samples from 402 patients enrolled in a multicentre cohort were frozen for analysis by mid-infrared fibre evanescent wave spectroscopy. The calibration cohort was divided into two groups of patients (septic arthritis and non-septic arthritis) and relevant spectral variables were used for logistic regression model. Model performances were tested on an independent set of 86 freshly obtained SF samples from patients enrolled in a single-centre acute arthritis cohort and spectroscopic analyses performed at the patient's bedside. RESULTS: The model set-up, using frozen-thawed SFs, provided good performances, with area under the curve 0.95, sensitivity 0.90, specificity 0.90, positive predictive value 0.41 and negative predictive value 0.99. Performances obtained in the validation cohort were area under the curve 0.90, sensitivity 0.92, specificity 0.81, positive predictive value 0.46 and negative predictive value 0.98. The septic arthritis probability has been translated into a risk score from 0 to 4 according to septic risk. For a risk score of 0, the probability of identifying a septic patient is very low (negative predictive value of 1), whereas a risk score of 4 indicates very high risk of septic arthritis (positive predictive value of 1). CONCLUSION: Mid-infrared fibre evanescent wave spectroscopy could distinguish septic from non-septic synovial arthritis fluids with good performances, and showed particular usefulness in ruling out septic arthritis. Our data supports the possibility of technology transfer. TRIAL REGISTRATION: ClinicalTrials.gov, http://clinicaltrials.gov, NCT02860871.

ABSTRACT

OBJECTIVE: To establish a new predictive score for the diagnosis of septic arthritis (SA) according to different synovial fluid (SF) variables. METHODS: First, we analysed the different clinical, biological and SF variables associated with the diagnosis of SA (according to the Newman's criteria) in a monocentric cohort of acute arthritis (<30 days) (n = 233) (SYNOLACTATE cohort). A new score predictive of SA (RESAS) was created using the independent discriminant variables after multivariate analysis. A value was attributed to each variable of the score according to the weighting based on their likelihood ratio for the diagnosis of SA. RESAS performance was then tested on the first cohort (internal validation) and then checked on a second independent cohort (n = 70) (external validation). RESULTS: After multivariate analysis, four independent variables of the SF were included for RESAS: (i) purulent SF or white blood cells count ≥70 000/mm3; (ii) absence/presence of crystals; (iii) lactate; and (iv) glucose synovial level. RESAS ranged between -4 and +13 points. The performance of RESAS to predicted SA was excellent with area under the curve (AUC)=0.928 (0.877-0.980) in internal validation and AUC=0.986 (0.962-1.00) in external validation. For a RESAS threshold ≥+4, SA was diagnosed with Se=56.0% (0.371-0.733), Sp=98.1% (0.952-0.993), LR+=29.1 (10.4-81.6) in the first cohort and with Se=91.7% (0.646-0.985), Sp=98.3% (0.909-0.997), LR+=53.2 (7.56-373) in the second cohort. CONCLUSION: RESAS is a new composite score of four SF variables with excellent performance to predicted SA in acute arthritis population.

ABSTRACT

OBJECTIVE: To evaluate the diagnostic performance of the synovial lactate, glucose and lactate/glucose ratio assay for the diagnosis of septic arthritis. METHODS: In this monocentric cross-sectional study, synovial fluids were prospectively obtained from patients with acute joint effusion (<30 days) on native joint. Septic arthritis was defined using Newman's criteria. To evaluate diagnostic performance, Receiver Operating Characteristic (ROC) curves with Area under the curve (AUC), Sensitivities (Se), Specificities (Sp), LR+ their 95% confidence intervals were calculated. Synovial fluid cultures with gram staining, crystal analyses, synovial fluid white blood cell counts (WBC), lactate and glucose assays were performed. RESULTS: A total of 233 synovial fluids were included. 25 patients had septic arthritis and 208 had non-septic arthritis (104 crystal-induced arthritis, 15 RA, 8 SpA, 6 reactive arthritis, and 75 acute arthritis of undifferentiated origin). Synovial lactate/glucose ratio performed higher than the synovial lactate or glucose assay separately (AUC: 0.859 [0.772-0.945]). Best synovial lactate/glucose ratio threshold to differentiate septic arthritis from non-septic arthritis was 5 Se 52% [0.34-0.7], Sp 98.1% [0.95-0.99], LR+ 27.0[9.50-76.00]). CONCLUSION: The diagnostic performance of synovial lactate/glucose allows septic arthritis to be effectively and very quickly distinguished from other types of arthritis.

ABSTRACT

OBJECTIVE: Steroid injections are common after an ultrasound-guided puncture and lavage (UGPL) of calcific tendonitis of the rotator cuff. However, steroids may prevent calcification resorption and negatively affect tendon healing. Our study was designed to determine whether saline solution was non-inferior to steroids in the prevention of acute pain reactions in the week following UGPL. METHODS: This was a randomised, double-blinded, controlled non-inferiority trial with 12-month follow-up. We included 132 patients (66 in each group) with symptomatic calcification measuring more than 5 mm. Patients received 1 mL of saline or steroid (methylprednisolone 40 mg) in the subacromial bursa at the end of UGPL. Primary outcome was the maximal pain during the week following the procedure with a prespecified non-inferiority margin of 10 mm (0-100 visual analogue scale). Secondary outcomes included pain at rest and during activity, function (disabilities of the arm, shoulder and hand score) and radiological evolution of the calcification over the 12-month follow-up. RESULTS: The estimated mean difference in the first week's maximal pain between these two groups was 11.76 (95% CI 3.78 to 19.75). Steroids significantly improved VAS pain at rest and during activities, as well as function at 7 days and 6 weeks. They did not change the rate of calcification resorption, which occurred in 83% and 74% of patients at 12 months in the saline and steroid groups. CONCLUSION: Non-inferiority of saline when compared with steroids could not be established. However, steroid injection improved pain in the 6 weeks following the procedure, and function in the 3 months after, with no significant effect on calcification resorption.

ABSTRACT

To assess the diagnostic value of ultrasound-guided (US-guided) synovial biopsy in routine clinical practice in cases of acute and chronic arthritis. A retrospective, single-center study of US-guided synovial biopsies between 2003 and 2013. The clinical, laboratory, radiographic, synovial fluid, and histological and bacteriological results of synovial biopsies were analyzed. Arthritis was classified according to disease duration < 6 weeks (AA) or ≥ 6 weeks (CA). Synovial biopsy success rate was defined by the rate of capsular and/or synovial tissue analyzed. The diagnostic efficiency was defined by synovial biopsy success rate multiplied by the clinical utility (validation of a diagnostic hypothesis leading to a specific therapy). One hundred seventy-six US-guided synovial biopsies (51 AA and 125 CA) were analyzed. Synovial biopsy success rate was 82.4%. The diagnostic efficiency was 19.9%. Among the acute arthritis cases, 11 were septic. Only three patients had a positive biopsy culture while the synovial fluid puncture was of insufficient quantity to allow bacteriological analysis. The perivascular infiltration of neutrophils (PMN) had a sensitivity of 81.8%, a specificity of 84.2%, and a positive likelihood ratio of 5.2 for the septic arthritis diagnosis. Among the chronic arthritis cases, no case of pyogenic septic arthritis was found. No histological lesions, examined separately, were specific to a type of chronic inflammatory joint disease. US-guided synovial biopsies remain relevant for the diagnosis of septic arthritis, in cases of acute arthritis when joint aspiration is not possible.

ABSTRACT

OBJECTIVES: The aims of this study in SLE population were (1) to describe ultrasonography (US) joint abnormalities, (2) to estimate the reliability of clinical swollen joint count (C-SJC) and SLEDAI (C-SLEDAI) versus US-SJC and US-SLEDAI scores, (3) to highlight specific patterns of lupus patients with Power Doppler (PD) abnormalities. METHOD: For this cross-sectional multicenter study, 151 consecutive adult SLE patients were recruited. Evaluation included a clinical standardized joint assessment, B-mode and PD US of 40 joints and 26 tendons blinded for clinical examination. Reliability and agreement between clinical and B-mode US were calculated using the intraclass correlation coefficients (ICC [95% Confidence Interval]). RESULTS: We found a very high frequency of subclinical US abnormalities in asymptomatic patients: 85% of patients without joint symptoms had at least 1 US abnormality. Among them 46 patients (87%) had a history of joint involvement. The most frequent abnormalities were joint effusmaions (108 patients), synovial hypertrophy (SH, 109 patients) and synovitis (61 patients). Joint or tendon PD signal (grade>1) was found in 44% of patients (67/151). Synovitis were mainly located especially on MCPs and wrists. Even if reliability between clinical and grey-scale US SJC assessments was poor, reliability between clinical and US SLEDAI was good. Comparison between SLE patients with and without PD signal did not show any specific SLE pattern. CONCLUSION: US may be useful to assess joint involvement in SLE patients but did not significantly change SLEDAI score.

ABSTRACT

BACKGROUND: Bilateral ankle arthritis is a classic diagnostic criterion for Löfgren syndrome. The objective of this study was to use ultrasonography to characterize the articular and periarticular involvement of the ankles in patients with Löfgren syndrome. METHODS: Multicenter descriptive cohort study of patients with Löfgren syndrome who underwent ultrasonography of the ankles. We collected clinical data, imaging study findings, blood test results, and joint fluid properties in patients who underwent joint aspiration. RESULTS: Findings from ultrasonography of the ankles in 40 patients were analyzed. The most common B-mode abnormality was subcutaneous edema (26/40), followed by tenosynovitis (22/40), with no differences in frequency across compartments. Joint involvement manifested as synovitis in 7 patients and effusion in 10 patients. Synovitis with increased vascularity by power Doppler was found in 3 patients. No statistically significant associations were found linking synovitis or tenosynovitis to clinical features (age and gender), laboratory tests, or imaging study findings. CONCLUSION: Contrary to the classical view, our results indicate that ankle involvement in Löfgren syndrome is more often abarticular than articular. The inclusion of bilateral ankle arthritis among the diagnostic criteria for Löfgren syndrome deserves reappraisal.

ABSTRACT

INTRODUCTION: Structural damage progression is a major outcome in rheumatoid arthritis (RA). Its evaluation and follow-up in trials should involve radiographic scoring by 1 or 2 readers (reference assessment), which is challenging in large longitudinal cohorts with multiple assessments. OBJECTIVES: To compare the reproducibility of multireader and reference assessment to improve the feasibility of detecting radiographic progression in a large cohort of patients with early arthritis (ESPOIR). METHODS: We used 3 sessions to train 12 rheumatologists in radiographic scoring by the van der Heijde-modified Sharp score (SHS). Multireader scoring was based on 10 trained-reader assessments, each reader scoring a random sample of 1/5 of all available radiographs (for double scoring for each X-ray set) for patients included in the ESPOIR cohort with complete radiographic data at M0 and M60. Reference scoring was performed by 2 experienced readers. Scoring was performed blindly to clinical data, with radiographs in chronological order. We compared multireader and reference assessments by intraclass correlation coefficients (ICCs) for SHS and significant radiographic progression (SRP). RESULTS: The intrareader and inter-reader reproducibility for trained assessors increased during the training sessions (ICC 0.79 to 0.94 and 0.76 to 0.92), respectively. For the 524 patients included, agreement between multireader and reference assessment of SHS progression between M0 and M60 and SRP assessment were almost perfect, ICC (0.88 (95% CI 0.82 to 0.93)) and (0.99 (95% CI 0.99 to 0.99)), respectively. CONCLUSIONS: Multireader assessment of radiographic structural damage progression is comparable to reference assessment and could be used to improve the feasibility of radiographic scoring in large longitudinal cohort with numerous X-ray evaluations.
