RESUMEN
Objective: Pregnancy may influence the course of inflammatory rheumatic diseases and, conversely, rheumatic and musculoskeletal diseases (RMDs) can affect the outcome of pregnancy. This study aimed to retrospectively analyse the outcome of pregnancy and disease in women with RMDs.Method: Subjects were patients with high-risk pregnancy and connective tissue diseases (CTDs) or inflammatory joint diseases (IJDs) managed at a specialized rheumatology outpatient clinic from 2007 to 2014. Data from conception to 6 months postpartum were collected from medical records and a questionnaire, and analysed regarding clinical symptoms, medications, pregnancy complications, birth outcomes, and infant development. Generalized estimating equations were used to compare the groups (CTD vs IJD).Results: The eligible 66 pregnancies in 57 RMD patients were divided into two groups by RMD type: CTD (n = 48) or IJD (n = 18). The live birth rate was 97% overall. Pregnancy complications (excluding two twin pregnancies) were incurred in 39.1%: miscarriage (n = 2), premature delivery (n = 12), small-for-gestational-age infants (n = 5), and/or pregnancy-related diseases (n = 14). Three children born to women with CTDs had affected development (autism spectrum disorder, congenital heart disease, bronchopulmonary dysplasia). CTD infants had a significantly lower mean gestational age (in weeks) (p = 0.042), weight (p = 0.009), and length (p = 0.016) at birth than IJD infants.Conclusion: Although the live birth rate was high, complications occurred in 39.1% of pregnancies in this cohort. Therefore, interdisciplinary management of pregnant women with RMDs at specialized clinics is strongly recommended.

We report the case of a 73-year-old female patient with malignant melanoma who developed rapidly progressive dermatosclerosis of the arms and legs as well as myalgia and flexion contractures during treatment with the immune checkpoint inhibitor nivolumab. The diagnosis of a myofasciitis was confirmed by imaging and biopsy. Following consultation with the treating dermato-oncologists nivolumab treatment was paused and treatment with methotrexate and prednisolone was initiated. Immune checkpoint inhibitors can induce a variety of immune-mediated side effects and can also imitate symptoms of rheumatological diseases. The occurrence of myofasciitis under immune checkpoint inhibition has been reported in the literature only in a few cases. Further oncological and rheumatological treatment management should be carried out in close interdisciplinary coordination.

Psoriatic arthritis (PsA) is a heterogeneous multifactorial disease with musculoskeletal involvement, which can be manifested as monoarthritis, oligoarthritis or polyarthritis and in some patients can also affect the axial skeleton. The most frequent indications of inflammation are bone marrow edema and enthesitis. The early and differential diagnosis of PsA is a clinical challenge, particularly as a differential diagnosis from other inflammatory or degenerative diseases of joints. Inflammatory joint and tendon alterations in the region of the extremities and the spine can be visualized with high sensitivity by the use of magnetic resonance imaging (MRI), musculoskeletal sonography (US) and fluorescence optical imaging (FOI). The use of MRI has a prognostic value with respect to the further radiographic course of the disease, particularly in the initial stages of the disease. Structural damage can be specifically and also partially demonstrated 3dimensionally in peripheral joints and the spine by the use of computed tomography (CT) and conventional Xray imaging. High-resolution peripheral quantitative CT (HR-pQCT) in particular, can visualize pathophysiological processes and the morphological consequences even in early stages of the disease. The values of conventional Xray diagnostics, CT, MRI, musculoskeletal US and alternative imaging procedures are presented with respect to the diagnostics and prognosis of the progression of patients with PsA.

A 46-year-old female patient with a known HIV-2-infection suffered from adult onset Still's disease, which was initially complicated by a macrophage activation syndrome (MAS). The required glucocorticoid treatment induced a psychosis and the patient developed an aversion to glucocorticoids. After failure of treatment with anakinra, an alternative option with the JAK-inhibitor tofacitinib was introduced because of the short half-life and to reduce glucocorticoid exposure. A switch to tofacitinib was only successful after an overlapping treatment with anakinra and tofacitinib for 3 weeks. The patient is currently being treated with monotherapy with tofacitinib as well as NSAID on demand, is in stable remission and can continue working as normal.

Rheumatic diseases are among the most common chronic inflammatory disorders. Besides severe pain and progressive destruction of the joints, rheumatoid arthritis (RA), spondyloarthritides (SpA) and psoriatic arthritis (PsA) impair working ability, reduce quality of life and if treated insufficiently may enhance mortality. With the introduction of biologics to treat these diseases, the demand for biomarkers of early diagnosis and therapeutic stratification has been growing continuously. The main goal of the consortium ArthroMark is to identify new biomarkers and to apply modern imaging technologies for diagnosis, follow-up assessment and stratification of patients with RA, SpA and PsA. With the development of new biomarkers for these diseases, the ArthroMark project contributes to research in chronic diseases of the musculoskeletal system. The cooperation between different national centers will utilize site-specific resources, such as biobanks and clinical studies for sharing and gainful networking of individual core areas in biomarker analysis. Joint data management and harmonization of data assessment as well as best practice characterization of patients with new imaging technologies will optimize quality of marker validation.

BACKGROUND: In rheumatoid arthritis (RA), hand synovitis appears especially in wrist, metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. In hand osteoarthritis (OA), potential inflammatory changes are mainly present in PIP and distal interphalangeal (DIP) joints. Joint inflammation can be visualised by fluorescence optical imaging (FOI) and musculoskeletal ultrasound (US). OBJECTIVE: Comparison of the amount and distribution of inflammatory signs in wrist and finger joints of the clinically dominant hand in patients with OA and RA by FOI and gray-scale (GSUS) and power Doppler US (PDUS). METHODS: FOI and GSUS/PDUS were performed in 1.170 joints (wrists, MCP, PIP, DIP) in 90 patients (67 RA, 23 OA). Joint inflammation was graded by a semiquantitative score (0-3) for each imaging method. RESULTS: GSUS/PDUS showed wrist and MCP joints mostly affected in RA. DIP joints were graded higher in OA. In FOI, RA and OA featured inflammatory changes in the respective joint groups depending on the phase of fluorescence dye flooding. CONCLUSIONS: US and FOI detected inflammation in both RA and OA highlighting the inflammatory component in the course of OA. The different inflammatory patterns and various shapes of fluorescence enhancement in FOI may offer opportunities to distinguish and determine the inflammatory status in both diseases.

Sonographic examination of joints has become a decisive component in rheumatological diagnostics and is now indispensible in the clinical routine. The exceptional representation of acute inflammatory soft tissue processes, very early recognition of bony destruction and the ubiquitous availability of the method have been major contributors to this success. In recent years there have been new developments in technology and in examination methods. The substantial importance of sonography for early detection of arthritis, differential diagnostics, therapy monitoring and estimation of prognosis is underlined by the continuously increasing number of international publications. Several scoring systems have been developed for small and large joints and have been proven not only under study conditions but also in practice. Subclinical inflammatory processes which are held responsible for the so-called silent progression can be detected using sonography.

This review presents an overview of the range of imaging modalities used in the diagnostic evaluation of patients with psoriatic arthritis (PsA). Conventional radiography is used to detect structural changes of the joints and tendon attachments. These changes occur late in the course of PsA hence conventional radiography contributes little to the early detection of PsA; however, the detection of periosteal proliferations on radiographs allows a relatively specific diagnosis of PsA. Skeletal scintigraphy and computed tomography are rarely used in PsA. Arthrosonography (ultrasound of the joints) is gaining increasing importance in the early identification of inflammatory soft tissue signs of PsA in the peripheral joints. Sonography enables early detection of synovitis and tenosynovitis as well as superficial erosions and also inflammatory processes of the tendon attachments. Magnetic resonance imaging (MRI) is indispensable for identifying possible involvement of the axial skeleton. Moreover, it allows good visualization of periostitis and arthritis. High resolution microcomputed tomography is an interesting novel diagnostic tool which allows highly sensitive evaluation of the bone structure and can detect very tiny bone lesions where typical signs of PsA are omega-shaped erosions and small corona-like spikes. Another interesting new diagnostic technique is fluorescence optical imaging (FOI) with the Xiralite system which is highly sensitive for detecting inflammatory processes of the hands.

OBJECTIVES: This study aimed at evaluating the effect of genicular nerve block (GNB) in juvenile idiopathic arthritis (JIA) patients with persistent unilateral knee arthritis on pain, inflammatory parameters, function, and range of motion. METHODS: A total of 104 JIA patients were diagnosed according to the International League Against Rheumatism (ILAR) criteria with persistent unilateral knee arthritis. They were allocated randomly into 2 groups: group 1 treated with GNB, while group 2 was treated with intra-articular triamcinolone (TA) only. Visual analogue scale (VAS) on pain, sonography of large joints in rheumatology (SOLAR) scoring system, and Lysholm scores were assessed at 0-, 2-, and 12-week intervals. Swelling and tenderness were clinically evaluated semi-quantitatively (0-3) at the same time intervals. RESULTS: VAS pain, tenderness, swelling, and SOLAR grey scale (GS) and power Doppler (PD) scores were significantly reduced after 2 weeks in both groups (p < 0.05). This was greater in the GNB group regarding VAS and tenderness, while SOLAR and swelling were stronger reduced in TA group. After 12 weeks, all outcome measures showed lower values in the GNB group compared to TA, and this was significant regarding VAS pain. Moreover, Lysholm functional score was significantly increased in both groups at both intervals; and higher values were seen in the TA group compared to GNB after 2 weeks. CONCLUSION: GNB was able to control pain and improve function and inflammation of the knee joint in JIA patients. Though steroid attained better results after 2 weeks, GNB achieved an equivalent longer-term improvement after 12 weeks. TRIAL REGISTRATION IDENTIFYING NUMBER: NCT04687930. Key Points ⢠Persistent knee arthritis treatment in JIA is always challenging. ⢠GNB was approved for treatment of pain in knee osteoarthritis. ⢠GNB in the present study succeeded to control active knee arthritis and this effect was comparable to intra-articular steroid injection.

BACKGROUND: There is no international consensus on an optimal ultrasound score for monitoring of rheumatoid arthritis (RA) on patient-level yet. Our aim was to reassess the US7 score for the identification of the most frequently pathologic and responsive joint/tendon regions, to optimize it and contribute to an international consensus. Furthermore, we aimed to evaluate the impact of disease duration on the performance of the score. METHODS: RA patients were assessed at baseline and after 3 and 6 months of starting/changing DMARD therapy by the US7 score in greyscale (GS) and power Doppler (PD). The frequency of pathologic joint/tendon regions and their responsiveness to therapy were analyzed by Friedman test and Cochrane-Q test respectively, including the comparison of palmar vs. dorsal regions (chi-square test). The responsiveness of different reduced scores and the amount of information retained from the original US7 score were assessed by standardized response means (SRM)/linear regression. Analyses were also performed separately for early and established RA. RESULTS: A total of 435 patients (N = 138 early RA) were included (56.5 (SD 13.1) years old, 8.2 (9.1) years disease duration, 80% female). The dorsal wrist, palmar MCP2, extensor digitorum communis (EDC) and carpi ulnaris (ECU) tendons were most frequently affected by GS/PD synovitis/tenosynovitis (wrist: 45%/43%; MCP2: 35%/28%; EDC: 30%/11% and ECU: 25%/11%) and significantly changed within 6 months of therapy (all p ≤0.003 by GS/PD). The dorsal vs. palmar side of the wrist by GS/PD (p < 0.001) and the palmar side of the finger joints by PD (p < 0.001) were more frequently pathologic. The reduced US7 score (GS/PD: palmar MCP2, dorsal wrist, EDC and ECU, only PD: dorsal MCP2) showed therapy response (SRM 0.433) after 6 months and retained 76% of the full US7 score's information. No major differences between the groups of early and established RA could be detected. CONCLUSIONS: The wrist, MCP2, EDC, and ECU tendons were most frequently pathologic and responsive to therapy in both early and established RA and should therefore be included in a comprehensive score for monitoring RA patients on patient-level.

PURPOSE: To evaluate wrist and finger joints in patients with rheumatoid arthritis (RA) by grayscale, power Doppler (PD) and contrast-enhanced musculoskeletal ultrasonography (US) and to compare these findings with MRI, clinical (DAS28) and laboratory (ESR; CRP) data. MATERIALS AND METHODS: US was performed at baseline (t0) and after three, six and twelve (t12) months before and after a change of medical treatment. MRI was carried out at t0 and t12 and used as the reference method. Contrast-enhanced US was used to assess one clinically most affected joint region. Different semiquantitative synovitis scores were calculated by grayscale and PD US. RESULTS: Contrast-enhanced US results evaluated by enhancement, slope and semi-quantitative assessment significantly correlated to each other, to grayscale US, CRP, as well as to MRI with the highest correlation coefficients for the used contrast-enhanced US modes (r = 0.56, r = 0.55, r = 0.57; each p < 0.05). Sum scores evaluated by grayscale US showed that synovial inflammation in finger joints was detected significantly more frequently in the palmar aspect than on the dorsal side (p = 0.001). Using power Doppler US, the wrists were significantly more inflamed from dorsal than on the palmar side (p = 0.0004). Significant longitudinal correlations between grayscale and power Doppler US scores were detected. CONCLUSION: Grayscale, power Doppler and contrast-enhanced US are accurate tools for the detection and follow-up of synovitis in RA wrist and finger joints, with contrast-enhanced US being most sensitive compared to MRI. All imaging methods reflected a good response to TNFα blocking therapy.

BACKGROUND: Digital ulcers (DU) present a challenging complication in systemic sclerosis (SSc). The aim of this study was to combine clinical characteristics and imaging methods to a composite score for the prediction of DU in SSc patients. METHODS: Seventy-nine SSc patients received clinical examination, their patient history was taken and nailfold capillaroscopy (NC), colour Doppler ultrasonography (CDUS) and fluorescence optical imaging (FOI) of the hands were performed at baseline. Newly developed DU over a period of approximately 12 months were registered. We used criteria with area under the curve (AUC) of at least 0.6 in regard to the development of these new DU to create the score (CIP-DUS, clinical features, imaging, patient history-digital ulcer score). RESULTS: Twenty-nine percent of all SSc patients developed new DU during follow-up (48.1% diffuse, 18.4% limited SSc). Based on the cross-validated (cv) AUC, a weight (cvAUC > 0.6 and ≤ 0.65: 1; cvAUC > 0.65 and ≤ 0.7: 2; cvAUC > 0.7: 3) was assigned to each selected parameter. The performance of the final CIP-DUS was assessed with and without the CDUS/FOI component. For the scleroderma patterns in NC, three points were appointed to late, two to active and one point to early capillaroscopy pattern according to Cutolo et al. The CIP-DUS including the CDUS and FOI parameters resulted in a good diagnostic performance (AUC after cross-validation: 0.83, 95%CI 0.74 to 0.92) and was well calibrated (chi-square = 12.3, p = 0.58). The cut-off associated with the maximum of sensitivity and specificity was estimated at ≥ 10 points resulting in a sensitivity of 100% and specificity of 74% for new DU during follow-up. Excluding CDUS and FOI parameters leads to a non-statistically significant lower performance (AUC after cross-validation: 0.81, 95%CI 0.72 to 0.91). However, including CDUS and FOI resulted in a better classification of patients in respect to the outcome new DU in follow-up due to significantly better reclassification performance (NRI = 62.1, p = 0.001) and discrimination improvement (IDI = 9.7, p = 0.01). CONCLUSION: A new score was introduced with the aim to predict digital ulcers. If applied correctly and with the new imaging techniques proposed, all patients at risk of digital ulcers throughout 12 months could be identified.

OBJECTIVES: To investigate the frequency of subclinical skin inflammation in both hands by fluorescence optical imaging (FOI) in patients with psoriasis/psoriatic arthritis (Pso/PsA) vs. rheumatoid arthritis (RA) and healthy individuals, and to correlate these findings with cardiovascular (CV) risk factors. PATIENTS AND METHODS: The FOI scans were analyzed retrospectively to detect clinically invisible skin enhancement (0-3 scale) in both hands without relationship to underlying joints or blood vessels. We further characterized the FOI patterns and sorted the scans into groups based on the assumed diagnosis (Pso/PsA, RA, and healthy controls), which was compared with the physician's diagnosis. Furthermore, the associations between CV risk factors and imaging findings were investigated by regression analyses. RESULTS: We included FOI scans of patients with Pso/PsA (n = 80), RA (n = 78), and healthy controls (n = 25). Subclinical skin enhancement on the back of their hands was more common in Pso/PsA (72.5%) than in RA patients (20.5%) and healthy individuals (28.0%) (p < 0.001). Based on the FOI pattern, the majority of patients with Pso/PsA (72.5%), RA (76.9%), and healthy controls (68.0%) were classified correctly using the physician-based diagnosis as reference (overall agreement of 74%, kappa = 0.57). No CV risk factors except body weight (kg) were associated with subclinical skin enhancement (OR 1.04, 95% CI 1.02-1.06; p < 0.001). CONCLUSION: Subclinical subdermal skin inflammation was common in Pso/PsA patients using FOI. Based on the FOI pattern, most patients with Pso/PsA and were classified with the correct diagnosis. We demonstrated an important influence of the body weight on our FOI results. FOI may be a helpful novel tool to study microcirculation in rheumatic diseases with skin involvement.

Objective: Fluorescence Optical Imaging (FOI) demonstrates indocyanine green (ICG)-enhanced microcirculation in wrist and finger joints, as a sign of inflammation. We wanted to assess the reliability of three FOI scoring methods from Berlin, Stockholm, and Copenhagen, to assess the validity of FOI with MRI as reference and to compare enhancement in hand joints in erosive hand osteoarthritis (OA) vs. rheumatoid arthritis (RA). Design: Five readers scored all finger and wrist joints of 26 patients with erosive hand OA and RA on semi-quantitative 0-3 scales using three different FOI scoring methods. To evaluate inter-reader reliability, we calculated the intraclass correlation coefficients (ICC) for sum scores and prevalence and bias adjusted kappa values for ordinal scales (Pabak-OS) on joint level. Enhancement in joint groups in erosive hand OA vs. RA was compared using Mann-Whitney test. Sensitivities and specificities of FOI was calculated with MRI as reference for hand OA patients only. Results: We found moderate to good inter-reader reliability for all FOI scoring methods (Pabak-OS: 0.50-0.78, ICC: 0.43-0.85) and different patterns of enhancement in erosive hand OA vs. RA with significantly more FOI enhancement in DIP joints in erosive hand OA across all methods. With MRI as reference the different FOI scoring methods reached similar sensitivities (63-65%) and specificities (76-91%). Conclusion: FOI enhancement can be measured reliably in erosive hand OA and RA using three different scoring methods. More DIP enhancement in erosive hand OA patients and good agreement with MRI support the diagnostic performance of FOI.
RESUMEN
OBJECTIVE: Systemic sclerosis (SSc) can lead to ischemic complications such as digital ulcers (DUs). The aim of the study was to find predictors of DUs by clinical and new imaging methods. PATIENTS AND METHODS: All 79 SSc patients included in the study received a clinical, colour Doppler ultrasound (CDUS), fluorescence optical imaging (FOI) and capillaroscopy examination at baseline, and their capacity to predict new DU development was analysed in 76 patients at 12 months follow-up. RESULTS: Twenty-two of 76 patients (28.9%) developed new ulcers during follow-up (diffuse SSc 48.1%; limited SSc 18.4%). Receiver operating characteristic (ROC) curve analysis revealed an area under the curve of 0.7576 for DU development, with a specificity of 87% and a sensitivity of 54.6% (p = 0.0003, OR = 8.1 [95%CI 2.5-25.6]) at a cut-off of ≥ 21 points (ACR/EULAR classification criteria for SSc). Capillaroscopy and CDUS had high sensitivity (100% and 95.5%) but low specificity (28.9% and 22.2%) for ulcer occurrence when used alone, but better specificity (46.3%) when combined (OR = 18.1 [95%CI 2.3-144.4]; p = 0.0004). Using FOI, fingers with pathologic staining had a higher risk for new ulcer development in the same finger (p = 0.0153). General future DU (i.e. DU also in other fingers) was associated with a missing FOI signal in the right digit III at baseline (p = 0.048). CONCLUSION: New imaging modalities can predict digital ulcer development in SSc patients with high sensitivity for capillaroscopy and CDUS and enhanced specificity when combined. A missing signal of FOI in the right digit III at baseline was associated with general future DU.

The objectives of this study are to evaluate a new semi-quantitative (0-5) musculoskeletal ultrasound (US) erosion score in patients with rheumatoid arthritis (RA) and to prove its usefulness in the detection of disease activity and success of therapy. Thirty-eight patients with RA (mean disease duration 10.1 ± 11.9 years) were enrolled. Start or change of therapy (DMARD/biologics) was an inclusion criterion. DAS28, laboratory (ESR and CRP) and US data were evaluated before new therapy initiation and after 1, 3, 6 and 12 months. Thirteen joints of the clinically more affected hand and forefoot (wrist and MCP, PIP, MTP joints 2-5) were analyzed for synovitis in grayscale (GS) and power Doppler (PD) US, tenosynovitis/paratenonitis in GS/PDUS (wrist, MCP level) and for erosions. Erosions were analyzed by a new semi-quantitative score (grade 0, no erosion; grade 1, <1 mm, grade 2, 1 to <2 mm; grade 3, 2 to ≤3 mm; grade 4, >3 mm; grade 5, multiple bone erosions). After 12 months, DAS28 decreased from 4.5 to 3.4 (p < 0.001), the synovitis score in GSUS from 26.3 to 12.8 (p = 0.001) and the synovitis score in PDUS from 10.6 to 4.1 (p < 0.001). The erosion score decreased from 21.5 to 18.1 (p = 0.046). There were longitudinal significant correlations between the new erosion score and both the DAS28 (r = 0.368; p = 0.025) and the synovitis score in PDUS (r = 0.365; p = 0.026) over a 1-year follow-up period. The new erosion score might be a useful tool for the evaluation of erosive changes by US in RA patients. In the course of DMARD and biologic therapy, it was responsive under 1-year follow-up examination.

OBJECTIVE: To assess the value of gray-scale (GS) and power Doppler (PD) ultrasound (US) in detecting inflammatory/destructive changes and for prediction of necessity of re-therapy with rituximab (RTX) in patients with rheumatoid arthritis (RA) over 1 year of followup. METHODS: GSUS and PDUS were performed to assess synovitis, tenosynovitis, and erosions on the clinically dominant hand and forefoot of 20 patients with RA before and after therapy with RTX. US parameters were compared with clinical (Disease Activity Score in 28 joints, tender/swollen joint counts, and patients' visual analog scale of disease activity) and laboratory parameters (C-reactive protein level and erythrocyte sedimentation rate). Results were compared for patients with and without re-therapy with RTX. RESULTS: Significant decreases in clinical and laboratory parameters were observed after 6 and 12 months. US synovitis scores significantly decreased after 6 and 12 months (P < 0.05 for each). Regarding patients who received re-therapy between 6 and 9 months after the start of therapy (n = 9), a fair therapy response was still detectable before re-therapy. In these patients, PD-positive synovitis was the only parameter that increased up to the 6-month examination. All patients negative for rheumatoid factor and anti-cyclic citrullinated peptide (n = 4) were in the group of patients receiving a second course of treatment. Seropositive patients showed a better response to treatment with less need for re-therapy. CONCLUSION: Response to therapy was measurable by clinical and laboratory parameters as well as by US. Since PDUS was able to detect the onset of disease activity before worsening of clinical symptoms occurred, PDUS is most helpful in evaluating disease activity and making earlier therapy decisions.

Objective. The main objective of this study was to evaluate the 7-joint ultrasound (US7) score by detailed joint region analysis of an arthritis patient cohort. Methods. The US7 score examines the clinically most affected wrist, MCP and PIP II, III, MTP II, and V joints for synovitis, tenosynovitis/paratenonitis, and erosions. Forty-five patients with rheumatoid arthritis (RA) (84.4%) and spondyloarthritis with polyarticular peripheral arthritis (PsA 13.3%; AS 2.2%) with a median disease duration of 6.5 yrs (range 7.5 mths-47.6 yrs) were included and examined at baseline and 3, 6, and 12 months after starting or changing therapy (DMARD/biologic). In this study, detailed US7 score joint region analysis was firstly performed. Results. The joint region analysis performed at baseline disclosed synovitis in 95.6% of affected wrists in the dorsal aspect by greyscale (GS) US where Grade 2 (moderate) was most often (48.9%) detected. Palmar wrist regions presented Grade 1 (minor) capsule elevation in 40% and Grade 2 (moderate synovitis) in 37.8%. Tenosynovitis of the extensor carpi ulnaris (ECU) tendon was found in 40%, with PD activity in 6.6%. Most of the erosions in MCP II were detected in the radial (68.9%), followed by the dorsal (48.9%) and palmar (44.4%) aspects. In MTP V, erosions were seen in 75.6% from lateral. Conclusions. Synovitis in GSUS was more often detected in the wrist in the dorsal than in the palmar aspect. ECU tendon involvement was frequent. Most erosions were found in the lateral scan of MTP V and the medial (radial) scan of MCP II.
RESUMEN
OBJECTIVE: To assess the inter- and intraobserver reliability of 26 rheumatologists when performing the 7-joint ultrasound score (US7). METHODS: Six patients with rheumatoid arthritis were examined by 26 sonographers in 12 rater groups who performed the US7 score. The US7 score includes the clinically dominant wrist, the second and third metacarpophalangeal (MCP) and proximal interphalangeal joints, and the second and fifth metatarsophalangeal (MTP) joints, which were evaluated for synovitis, tenosynovitis/paratenonitis, and erosions from the dorsal side and palmar/plantar aspects by gray-scale and power Doppler (PD) ultrasound. Additional lateral scans were performed at the MCP2 and MTP5 joints. All of the groups repeated the examination in 4 patients in order to calculate the intraobserver reliability. The results of one group that included 2 expert sonographers were considered as the reference standard. Kappa values, median agreement rates (interobserver), and P values (intraobserver evaluation) were calculated. RESULTS: The median overall kappa value for detecting synovitis was 0.51, for tenosynovitis/paratenonitis was 0.57, and for erosions was 0.45. In detail, the best interobserver results were found for the detection of erosions in the MTP2 joint from the plantar aspect (κ = 1; median agreement rate 89.4%) and for PD signal detection in the palmar wrist region (κ = 0.79; median agreement rate 78.8%). Good agreement was found for detecting erosions in the MCP2 joint from the radial side (κ = 0.67; median agreement rate 77.3%). CONCLUSION: The inter- and intraobserver reliability of the US7 score shows moderate to substantial kappa values and good agreements. Therefore, this ultrasound score has the potential to be an important imaging tool, including multicenter analysis to assess structural changes.

OBJECTIVE: To introduce a new standardized ultrasound score based on 7 joints of the clinically dominant hand and foot (German US7 score) implemented in daily rheumatologic practice. METHODS: The ultrasound score included the following joints of the clinically dominant hand and foot: wrist, second and third metacarpophalangeal and proximal interphalangeal, and second and fifth metatarsophalangeal joints. Synovitis and synovial/tenosynovial vascularity were scored semiquantitatively (grade 0-3) by gray-scale (GS) and power Doppler (PD) ultrasound. Tenosynovitis and erosions were scored for presence. The scoring range was 0-27 for GS synovitis, 0-39 for PD synovitis, 0-7 for GS tenosynovitis, 0-21 for PD tenosynovitis, and 0-14 for erosions. Patients with arthritis were examined at baseline and after the start or change of disease-modifying antirheumatic drug (DMARD) and/or tumor necrosis factor alpha (TNFalpha) inhibitor therapy 3 and 6 months later. C-reactive protein level, erythrocyte sedimentation rate, rheumatoid factor, anti-cyclic citrullinated peptide, Disease Activity Score in 28 joints (DAS28), and radiographs of the hands and feet were performed. RESULTS: One hundred twenty patients (76% women) with rheumatoid arthritis (91%) and psoriatic arthritis (9%) were enrolled. In 52 cases (43%), erosions were seen in radiography at baseline. Patients received DMARDs (41%), DMARDs plus TNFalpha inhibitors (41%), or TNFalpha inhibitor monotherapy (18%). At baseline, the mean DAS28 was 5.0 and the synovitis scores were 8.1 in GS ultrasound and 3.3 in PD ultrasound. After 6 months of therapy, the DAS28 significantly decreased to 3.6 (Delta = 1.4), and the GS and PD ultrasound scores significantly decreased to 5.5 (-32%) and 2.0 (-39%), respectively. CONCLUSION: The German US7 score is a viable tool for examining patients with arthritis in daily rheumatologic practice because it significantly reflects therapeutic response.
