Show moreObjective: Physical function is one of the Outcome Measures in Rheumatology (OMERACT) core outcome domains for hand osteoarthritis studies. Our aim was to select appropriate instrument(s) to measure this domain, as part of the development of a core outcome measurement set.Methods: Following the OMERACT Filter 2.1 instrument selection process, the (function subscale of) the Australian/Canadian Hand Osteoarthritis Index (AUSCAN), Functional Index for Hand Osteoarthritis (FIHOA) and Michigan Hand Outcomes Questionnaire (MHQ) were assessed for domain match, feasibility, truth and discrimination. Data gathered from available literature, working group and patient surveys, and additional analyses in two hand osteoarthritis cohorts were used to inform a consensus process.Results were summarized in Summary of Measurements Properties tables and reviewed by the OMERACT technical advisory group. Results: MHQ passed the assessment of domain match and feasibility by the working group and patient research partners. For AUSCAN important limitations in feasibility were noted, but domain match was good. FIHOA did not pass the assessment and was not taken through the follow-up assessment. Based on published literature, reliability and construct/longitudinal validity of both MHQ and AUSCAN fulfilled OMERACT standards. While clinical trial discrimination and thresholds of meaning were good for AUSCAN, results for MHQ were ambiguous.Conclusion: MHQ was provisionally endorsed as OMERACT core outcome measure for the core domain physical function. While AUSCAN may have better metric properties than MHQ, it received provisional endorsement as a second measure of function due to important feasibility issues. A research agenda to merit full endorsement was set. (c) 2021 The Author(s). Published by Elsevier Inc. Show less

Show moreBackground: Hand osteoarthritis (HOA) is a highly prevalent rheumatic disease that predominates in females and causes pain and loss of functional capacity. Obesity and metabolic syndrome have been previously suggested to associate with the severity of HOA, but clarity on these associations is yet to be achieved.Objective: Test the association between obesity and other components of the metabolic syndrome and disability in women with hand osteoarthritis (HOA).Design: Individuals from EpiReumaPt epidemiological community-based study (2011-2013) are representative of the Portuguese population. Women with diagnosis of primary HOA were included.Primary outcome: hand functional status, assessed by Cochin questionnaire.Secondary outcomes: hand pain, assessed by visual analogue scale and tender hand joint count (THJ).Explanatory variables: obesity, diabetes mellitus, arterial hypertension and hypercholesterolemia. Possible associations between obesity and the other components of metabolic syndrome with Cochin score, hand pain and THJ were tested in a multivariable linear regression model.Potential confounders considered: age, education level and countrywide distribution.Results: 473 women with primary HOA were included. Forty percent were overweight and 29% obese. Ninety-three (19.8%) participants had diabetes, 261 (55.8%) reported hypertension and 261 (55.9%) hypercholesterolemia. Mean Cochin score was 15.5 +/- 14.8, mean pain VAS was 4.7 +/- 2.6 and mean THJ 1.4 +/- 3. In the multivariable analysis, obesity (beta 4.6 CI 0.7;8.5) and diabetes (beta 4.0 CI 0.4;7.6) were found to significantly associate with HOA functional disability. In addition, diabetes, but not obesity, associated with hand pain. There was no association between obesity or diabetes with THJ.Conclusion: In a Portuguese female population with primary HOA, obesity and diabetes mellitus independently associated with a worse hand functional status. These data add to evidence suggesting a role of metabolic factors in the severity of HOA. Show less

Show moreObjective: To investigate determinants of decrease and increase in joint pain in symptomatic finger osteoarthritis (OA) on magnetic resonance (MR) imaging over 2 years.Design: Eighty-five patients (81.2% women, mean age 59.2 years) with primary hand OA (89.4% fulfilling American College of Rheumatology (ACR) classification criteria) from a rheumatology outpatient clinic received contrast-enhanced MR imaging (1.5T) and physical examination of the right interphalangeal finger joints 2-5 at baseline and at follow-up 2 years later. MR images were scored paired in unknown time order, following the Hand OA MRI scoring system (HOAMRIS). Joint pain upon palpation was assessed by research nurses. Odds ratios (ORs; 95% confidence intervals) were estimated on joint level (n = 680), using generalized estimating equations (GEE) to account for the within patient effects. Additional adjustments were made for change in MR-defined osteophytes, synovitis, and bone marrow lesions (BMLs).Results: Of 116 painful joints at baseline, at follow-up: 76 had less pain, 21 less synovitis, and 13 less BMLs. A decrease in synovitis (OR = 5.9; 1.12-31.0), but not in BMLs (OR = 0.39; 0.10-1.50), was associated with less pain. Of 678 joints without maximum baseline pain, at follow-up: 115 had increased pain, 132 increased synovitis, 96 increased BMLs, and 44 increased osteophytes. Increased synovitis (OR = 1.81; 1.11-2.94), osteophytes (OR = 2.75; 1.59-4.8), but not BMLs (OR = 1.14; 0.81-1.60), was associated with increased pain. Through stratification it became apparent that BMLs were mainly acting as effect modifier of the synovitisepain association.Conclusion: Decrease in MR-defined synovitis is associated with reduced joint pain, identifying synovitis as a possible target for treatment of finger OA.
