Does patients' opinion of remission in rheumatoid arthritis overlap ultrasound "true" remission? - a pilot study.

AIM: Patients describe rheumatoid arthritis (RA) remission as the absence of any symptoms or return to normality. Residual ultrasound (US) synovitis was frequently described in remission cohorts in previous studies. US tenosynovitis evaluation and scoring seems to better follow clinical remission scores compared with synovitis in RA. Our objective was to verify the presence of US findings suggestive of persistent inflammation in a cohort of patients in remission according to their own opinion. MATERIALS AND METHODS: Forty-three RA patients were prospectively enrolled in this pilot study between 2015-2017 according to their positive answer to the question "Are you feeling free of symptoms, just like before your RA symptomsstarted?". Clinical evaluation of tender and swollen joints was performed in the same day with US evaluation of 24 joints and 26 tendon sites and lab C-reactive protein (CRP) evaluation. DAS28-CRP and SDAI were calculated. RESULTS: A total of 72.9% (35 of 43) of patients were in remission per DAS28 criteria. Except for CRP value, no other variables were significantly different in the 35 of 43. PD scoring in tenosynovitis of the ankle and feet was 100% overlapping remission felt by patients. PD tenosynovitis in both upper and lower limbs was found in less than 10% of patients, and only grade 1 (minimal). CONCLUSION:  A combination of patients' opinion and PDUS evaluation could be a starting point for RA treatment tapering.

Power Doppler ultrasound monitoring of response to anti-tumour necrosis factor alpha treatment in patients with rheumatoid arthritis.

OBJECTIVES: To monitor by power Doppler US (PDUS) the short-term response to anti-TNFα therapy in six target joints of RA patients; to correlate PDUS findings with clinical assessments and laboratory indices of disease activity. METHODS: Consecutive RA patients starting anti-TNFα therapy were included and studied at baseline and 3 months later. Clinical (number of tender joints; number of swollen joints; Visual Analogue Scale; DAS28) and laboratory (ESR and CRP) assessments were performed. All patients were evaluated by PDUS at six target joints (II MCP, wrist, knee bilaterally). The components of synovitis (synovial hypertrophy, joint effusion, and power Doppler) were analysed and graded (0-3 semi-quantitative score). Moreover, by summing the PDUS findings, three different scores were calculated: a single inflammatory lesion score (0-18, for synovial hypertrophy, effusion, power Doppler), a joint score (0-18; at II MCP, wrist and knee joints) and a global score (0-54; sum of all abnormalities). RESULTS: Sixty-eight RA patients were studied. A significant decrease in the joint score in all articular sites (MCP, P = 0.003; knee, P = 0.002; wrist, P = 0.0001) as well as in the scores of the single components of synovitis (P = 0.0001-0.002) and in the global 6-joint score (P = 0.0001) was found. All clinical and laboratory parameters were significantly decreased at follow-up (P = 0.0001-0.001). A moderate significant positive correlation was observed between the global PDUS score and DAS28 (r = 0.38; P = 0.001). CONCLUSION: PDUS is a sensitive-to-change imaging modality for monitoring the short-term response to anti-TNFα treatment in RA patients. The assessment of a limited number of joints makes the evaluation feasible in rheumatology practice as a complementary tool to clinical assessment.

The use of musculoskeletal ultrasound in a rheumatology outpatient clinic.

INTRODUCTION: Musculoskeletal ultrasound (US) represents a valid, reliable and sensitive-to-change tool for the evaluation of patients suffering from rheumatic conditions. This method demonstrates a wide applicability and availability, finding place in the clinical practice in rheumatology outpatient clinic. AIM: To perform an epidemiological evaluation related to the use of US in a university rheumatology outpatient clinic. MATERIAL AND METHODS: During a 3-month period, data concerning consecutive patients attending to the US Unit of Department of Rheumatology, Sapienza University of Rome were registered. We collected the demographic data, the diagnosis, the reason for the US examination, the examined joints, as well as the requesting physicians' specialty. RESULTS: In the period October-December 2013, 572 patients (M/F 137/435; mean age+/-SD 55.2+/-15.8 years) were registered. The US examination was more frequently requested for the following diseases: rheumatoid arthritis (29.5%), osteoarthritis (10.6%), spondyloarthritis (9.1%), and connective tissue diseases (8.9%). In 239 of cases (41.8%), the US evaluation was requested for other indications. The US evaluation was requested slightly more frequently for monitoring (55.7%) compared to diagnosis (44.3%). The requesting physician was a rheumatologist in the majority of the cases (80.6%). The most frequent requested were the hand joints (28.9%) and wrists (23.3%). CONCLUSIONS: US examinations are most frequently used in the evaluation of patients with rheumatoid arthritis and mainly to monitor the disease. The exam is requested mostly by rheumatologists. The hand joints and wrists were the most frequently evaluated.
