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 ␣ (TNF␣) 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 TNF␣ inhibitors (41%), or TNF␣ 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 (⌬ ‫؍‬ 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.

The data support the hypothesis that anti-TNF therapy may exert beneficial effects on bone metabolism in RA patients.

Vertebral fractures due to osteoporosis are a common but frequently unrecognized complication in established ankylosing spondylitis (AS). It is known that inflammatory activity in rheumatic diseases (i.e., proinflammatory cytokines) itself plays a possible role in the pathophysiology of bone loss. The aim of this study was to analyze whether inflammatory activity and an alteration of the vitamin D metabolism play a substantial role in the loss of bone mass in AS. In this cross-sectional study, 58 patients with established AS and an age- and sex-matched control group were examined. The vitamin D status was investigated, as was, in parallel, the relationship to disease activity (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]), markers of bone metabolism (parathyroid hormone [PTH], 1.25 vitamin D3, 25 vitamin D3), calcium, bone alkaline phosphatase (bone-AP), urine cross-links, and plasma tumor necrosis factor alpha (TNFalpha). Bone mineral density was measured by quantitative computed tomography (QCT) of the lumbar spine. Osteoporosis was diagnosed in early as well as in progressive stages of AS (23/58=39.6%). Furthermore, serum levels of 1.25 vitamin D3 and PTH were negatively correlated with disease activity and TNFalpha. The excretion of cross-links showed a positive correlation with disease activity and TNFalpha, and 1.25 vitamin D3 and PTH were positively correlated with bone-AP. TNFalpha also positively correlated with disease activity. AS patients with osteoporosis showed significantly increased CRP, ESR, cross-links and PTH and a significantly decreased 1.25 D3. Osteoporosis is frequent in AS and high disease activity is associated with an alteration in vitamin D metabolites and increased levels of bone resorption in active AS. Our findings propose a close association of BMD, bone metabolism and inflammatory activity, possibly related to vitamin D inflammation interactions.

PurposeTo determine the sensitivity to change of the US7 score among RA patients under various therapies and to analyze the effect of each therapeutic option over 1 year. To estimate predictors for development of destructive bone changes.MethodsMusculoskeletal ultrasound (US7 score), DAS28, CRP and ESR were performed in 432 RA patients at baseline and after 3, 6 and 12 months. The cohort was divided into four sub-groups: first-line DMARDs (Group 1; 27.3%), therapy switch: DMARDs to second DMARDs (Group 2; 25.0%), first-line biologic after DMARDs therapy (Group 3; 35.4%) and therapy change from biologic to second biologic (Group 4; 12.3%).ResultsThe US7 synovitis and tenosynovitis sum scores in grey-scale (GSUS) and power Doppler ultrasound (PDUS) as well as ESR, CRP decreased significantly (p<0.05) after 12 months in group 1 to 3. Group 1+2 also illustrated a significant change of DAS28 after 1 year (p<0.001). Only in Group 4, the US7 erosion sum score decreased significantly from 4.3 to 3.6 (p=0.008) after 1 year. Predictors capable of forecasting US erosions after one year were: higher score of US7 synovitis (p<0.001), of US7 erosions in GSUS (p<0.001), as well as of DAS28 (p<0.001) at baseline.ConclusionsThe comparable developments of the US7 score with clinical and laboratory data illustrates its potential to reflect therapeutic response. Therefore, the novel US7 score is sensitive to change. Patients who switched from one biologic to another exhibited a significant decline in erosions after 12 months, while the erosions scores in the other groups were stable.

A combined "one-stop-shopping" MRI approach for PE and DVT was routinely feasible and detected 17% more cases of thromboembolism compared with separate examinations. MRI may be considered a second-line technique to avoid contraindications to CT but also a primary comprehensive technique for diagnosing thromboembolism.
