Tofacitinib and Baricitinib in Type 2 Diabetic Patients with Rheumatoid Arthritis.

Background and Objectives: Recently, a randomized controlled trial suggested a potential benefit of baricitinib in patients with diabetes mellitus, preserving ß-cell function. However, the clinical evidence currently available is limited. We aimed to assess the potential impact of tofacitinib and baricitinib on type 2 diabetes mellitus (T2DM) patients with rheumatoid arthritis. Materials and Methods: The candidates for this observational, retrospective, single-center study were selected from a cohort of 120 rheumatoid arthritis patients treated with tofacitinib or baricitinib between September 2017 and September 2023. The eligibility criteria included patients with T2DM who were receiving oral antidiabetic drugs (OADs). The primary outcome was the glycosylated hemoglobin (HbA1c) value after 6 months of a JAK inhibitor treatment. Secondary outcomes included body mass index (BMI) and rheumatoid arthritis disease activity. Differences were evaluated using Fisher's exact test, as well as the Mann-Whitney test or the Wilcoxon test. Results: Thirteen patients were included; 46.2% (6/13) underwent treatment with tofacitinib, while 53.8% (7/13) were treated with baricitinib. At 6 months, baricitinib treatment resulted in a reduction in HbA1c (p = 0.035), with 57.1% (4/7) of patients achieving values <7%, and 28.6% (2/7) of patients requiring a reduction in OAD dosage. Concerning BMI, an increase (p = 0.022) was observed at 6 months following baricitinib administration. All the patients treated with either tofacitinib or baricitinib achieved remission or low disease activity, without requiring statistically significant changes in concomitant rheumatoid arthritis treatment. Conclusions: In T2DM patients with rheumatoid arthritis, baricitinib can improve insulin sensitivity and glucose uptake, enabling the optimization of T2DM management.

Increase of Circulating Monocyte-Platelet Conjugates in Rheumatoid Arthritis Responders to IL-6 Blockage.

Platelets (PLT) bind to a significant percentage of circulating monocytes and this immunomodulatory interaction is increased in several inflammatory and autoimmune conditions. The therapeutic blockage of IL-6 with Tocilizumab (TCZ) alters PLT and the phenotype and function of monocytes in rheumatoid arthritis (RA). However, the relationship between monocyte−PLT conjugates (CD14+PLT+) and clinical and immunological variables and the regulation of this interaction by IL-6 blockage are still unknown. Here, we compared the presence of monocyte−PLT conjugates (CD14+PLT+) and membrane CD162 expression using flow cytometry, and, by ELISA, the markers of PLT activation (sCD62P and sCD40L) in healthy donors (HD) and patients with long-standing RA before TCZ (baseline). We found higher percentages and absolute counts of CD14+PLT+, and higher plasmatic levels of sCD62P and sCD40L but lower CD162 expression on monocytes from RA patients than those from HD. Additionally, the levels of CD14+PLT+ inversely correlated with inflammatory parameters. Interestingly, 95% of patients with lower percentages of CD14+PLT+ and only 63% of patients with higher percentages of CD14+PLT+ achieved a EULAR-defined response at four weeks (p = 0.036). After TCZ, the percentage of CD14+PLT+ increased in 92% of RA patients who achieved 12 w-remission (p < 0.001). Our results suggest that the binding of PLTs has a modulatory effect, accentuated by the increased binding of PLTs to monocytes in response to the therapeutic blockage of IL-6.

The inflammatory role of silent urate crystal deposition in intercritical gout.

OBJECTIVE: To study subclinical inflammation in intercritical gout patients and its relation to the estimated size of monosodium urate crystal deposition and cardiovascular risk factors. METHODS: We performed a secretome analysis and the quantification of cytokine and adipokine plasma levels [IL-1ß, IL-18, IL-6, soluble IL-6 receptor (sIL-6R), TNF-α, C-X-C motif chemokine 5, RANTES (Regulated upon Activation, Normal T Cell Expressed and Presumably Secreted), leptin, resistin and adiponectin] to analyse subclinical inflammation in intercritical gout patients. Since it is currently not feasible to determinate the whole body deposit of monosodium urate crystals, we created an indirect clinical classification to estimate it. Then we compared cytokine levels in controls and gout patients and in patients with different crystal deposition sizes. We also studied the association between cytokine-levels and the number of cardiovascular risk factors. RESULTS: Ninety consecutive patients attending a crystal arthritis unit were studied. IL-18, sIL-6R, RANTES, leptin and adiponectin were higher in intercritical gout patients than in controls. An association was observed between IL-18, sIL6-R and RANTES levels and the size of crystal deposition. IL-18, sIL6-R, RANTES and leptin were higher in patients with no cardiovascular risk factors compared with controls with no risk factors. CONCLUSION: Our results showed that the levels of some pro-inflammatory cytokines and metabolic proteins are elevated in intercritical gout patients. The levels of certain cytokines were related to the estimated size of the monosodium urate crystal deposition and to the number of cardiovascular risk factors. These cytokine changes may help to explain the increase in cardiovascular events in gout patients.

Metabolomics profiling predicts outcome of tocilizumab in rheumatoid arthritis: an exploratory study.

INTRODUCTION: To study metabolic signatures can be used to identify predictive biomarkers for a patient's therapeutic response. OBJECTIVES: We hypothesized that the characterization of a patients' metabolic profile, utilizing one-dimensional nuclear magnetic resonance (1H-NMR), may predict a response to tocilizumab in patients with rheumatoid arthritis (RA). METHODS: 40 active RA patients meeting the 2010 ACR/EULAR classification criteria initiating treatment with tocilizumab were recruited. Clinical outcomes were determined at baseline, and after six and twelve months of treatment. EULAR response criteria at 6 and 12 months to categorize patients as responders and non-responders. Blood was collected at baseline and after six months of tocilizumab therapy. 1H-NMR was used to acquire a spectra of plasma samples. Chenomx NMR suite 8.5 was used for metabolite identification and quantification. SPSS v.27 and MetaboAnalyst 4.0 were used for statistical and pathway analysis. RESULTS: Isobutyrate, 3-hydroxybutyrate, lysine, phenylalanine, sn-glycero-3-phosphocholine, tryptophan and tyrosine were significantly elevated in responders at the baseline. OPLS-DA at baseline partially discriminated between RA responders and non-responders. A multivariate diagnostic model showed that concentrations of 3-hydroxybutyrate and phenylalanine improved the ability to specifically predict responders classifying 77.1% of the patients correctly. At 6 months, levels of methylamine, sn-glycero-3-phosphocholine and tryptophan tended to still be low in non-responders. CONCLUSION: The relationship between plasma metabolic profiles and the clinical response to tocilizumab suggests that 1H-NMR may be a promising tool for RA therapy optimization. More studies are needed to determine if metabolic profiling can predict the response to biological therapies in RA patients.

Interactions between rheumatoid arthritis antibodies are associated with the response to anti-tumor necrosis factor therapy.

BACKGROUND: Blocking of the Tumor Necrosis Factor (TNF) activity is a successful therapeutic approach for 50-60% of rheumatoid arthritis (RA) patients. However, there are yet no biomarkers to stratify patients for anti-TNF therapy. Rheumatoid factor (RF) and anti-cyclic-citrullinated antibodies (anti-CCP) have been evaluated as biomarkers of response but the results have shown limited consistency. Anti-carbamylated protein (anti-CarP) and anti-peptidylarginine deiminase type 4 (anti-PAD4) antibodies have been much less studied. Despite being linked to common immune processes, the interaction between these markers has not been evaluated yet. Our aim was to analyze the interaction between these four antibodies in relation to the response to anti-TNF therapy. METHODS: For this objective, a prospective cohort of n = 80 RA patients starting anti-TNF therapy was recruited. Serum determinations at baseline were performed for RF, anti-CCP, anti-CarP and anti-PAD4 antibodies using enzyme-linked immunosorbent assays (ELISA). The clinical response to anti-TNF therapy was determined at week 12 using the change in DAS28 score. Association was performed using multivariate linear regression adjusting for baseline DAS28, sex and age. RESULTS: The interaction between pairs of antibodies was tested by the addition of an interaction term. We found two highly significant antibody interactions associated with treatment response: anti-CarP with anti-PAD4 (p = 0.0062), and anti-CCP with RF (p = 0.00068). The latter antibody interaction was replicated in an independent retrospective cohort of RA patients (n = 199, p = 0.04). CONCLUSIONS: The results of this study suggest that antibody interaction effects are important factors in the response to anti-TNF therapy in RA.

Phenotypic and Functional Consequences of PLT Binding to Monocytes and Its Association with Clinical Features in SLE.

Platelets (PLTs) can modulate the immune system through the release of soluble mediators or through interaction with immune cells. Monocytes are the main immune cells that bind with PLTs, and this interaction is increased in several inflammatory and autoimmune conditions, including systemic lupus erythematosus (SLE). Our aim was to characterize the phenotypic and functional consequences of PLT binding to monocytes in healthy donors (HD) and in SLE and to relate it to the pathogenesis of SLE. We analyzed the phenotypic and functional features of monocytes with non-activated and activated bound PLTs by flow cytometry. We observed that monocytes with bound PLTs and especially those with activated PLTs have an up-regulated HLA-DR, CD86, CD54, CD16 and CD64 expression. Monocytes with bound PLTs also have an increased capacity for phagocytosis, though not for efferocytosis. In addition, monocytes with bound PLTs have increased IL-10, but not TNF-α, secretion. The altered phenotypic and functional features are comparable in SLE and HD monocytes and in bound PLTs. However, the percentages of monocytes with bound PLTs are significantly higher in SLE patients and are associated with undetectable levels of anti-dsDNA antibodies and hematuria, and with normal C3 and albumin/creatinine levels. Our results suggest that PLTs have a modulatory influence on monocytes and that this effect may be highlighted by an increased binding of PLTs to monocytes in autoimmune conditions.

A treat-to-target approach for gout confers renoprotective effect in patients with chronic kidney disease stage 3.

The aim of this study was to assess changes in the estimated glomerular filtration rate (eGFR) in gouty patients with chronic kidney disease (CKD) using a "treat-to-target" (T2T) approach in gout. This multicenter observational retrospective study included patients diagnosed with gout and CKD stage 3 taking xanthine oxidase inhibitors (XOIs) (allopurinol or febuxostat) for at least 12 months. All patients were treated using a T2T strategy according to national gout guidelines to achieve the target levels of serum uric acid (sUA; < 5-6 mg/dl) within 6 months of the first visit. The primary outcome was to assess changes in eGFR. The effects of independent variables were analyzed over eGFR in a linear mixed-effects (LME) model. Fifty patients with gout and CKD stage 3 treated with XOIs with a T2T strategy for 12 months were included. Eighty-two percent of the patients achieved the sUA target during the study period. The improvement seen in eGFR was higher during the first 6 months, showing a median increase of 7.54 ml/min/m2 (SE = 1.25) and trending towards stability over 12 months. For every 1 mg/dl of decrease in sUA, an improvement of 1.5 ml/min/m2 in eGFR was observed (coefficient ± SE: - 1.58 ± 0.26) (p < 0.001) with no differences between type and dosage of XOIs treatment, colchicine administration, age, sex, and smoking status. A reduction in sUA levels using a T2T approach with XOIs at an optimal dose is possible and could help conserve and improve renal function in gouty patients with CKD stage 3.

Genetic variation at the glycosaminoglycan metabolism pathway contributes to the risk of psoriatic arthritis but not psoriasis.

OBJECTIVE: Psoriatic arthritis (PsA) is a chronic inflammatory arthritis affecting up to 30% of patients with psoriasis (Ps). To date, most of the known risk loci for PsA are shared with Ps, and identifying disease-specific variation has proven very challenging. The objective of the present study was to identify genetic variation specific for PsA. METHODS: We performed a genome-wide association study in a cohort of 835 patients with PsA and 1558 controls from Spain. Genetic association was tested at the single marker level and at the pathway level. Meta-analysis was performed with a case-control cohort of 2847 individuals from North America. To confirm the specificity of the genetic associations with PsA, we tested the associated variation using a purely cutaneous psoriasis cohort (PsC, n=614) and a rheumatoid arthritis cohort (RA, n=1191). Using network and drug-repurposing analyses, we further investigated the potential of the PsA-specific associations to guide the development of new drugs in PsA. RESULTS: We identified a new PsA risk single-nucleotide polymorphism at B3GNT2 locus (p=1.10e-08). At the pathway level, we found 14 genetic pathways significantly associated with PsA (pFDR<0.05). From these, the glycosaminoglycan (GAG) metabolism pathway was confirmed to be disease-specific after comparing the PsA cohort with the cohorts of patients with PsC and RA. Finally, we identified candidate drug targets in the GAG metabolism pathway as well as new PsA indications for approved drugs. CONCLUSION: These findings provide insights into the biological mechanisms that are specific for PsA and could contribute to develop more effective therapies.

Binding of Platelets to Lymphocytes: A Potential Anti-Inflammatory Therapy in Rheumatoid Arthritis.

Soluble factors released from platelets can modulate the immune response of leukocytes. We and others have recently found that T lymphocytes with bound platelets have reduced proliferation and IFN-γ and IL-17 production. Thus, we speculate that if we induce the binding of platelets to lymphocytes, we will be able to regulate the inflammatory response. When we cocultured platelets with lymphocytes at different ratios, we were able to increase the percentage of lymphocytes with bound platelets. The coculture of platelets with lymphocytes in the presence of stimulation decreased the production of IFN-γ and TNF-α, T cell proliferation, and the expression of CD25, PD-L1, and SLAM. However, this coculture increased CD39 expression. All of these effects were dependent on the dose of platelets and operated indistinctly with platelets from different healthy donors. When platelets were cocultured in the same compartment with lymphocytes, we observed less IFN-γ and TNF-α production and T lymphocyte proliferation than in cultures with platelets separated from lymphocytes by a 0.4-µm pore size filter. The binding of platelets to lymphocytes was blocked with anti-P-selectin Abs, and when this occurred we observed higher IFN-γ and TNF-α production than in nonblocked conditions. The cocultures of platelets with synovial fluid cells from rheumatoid arthritis patients reduced inflammatory cytokine production and increased IL-10 production. These results suggest that platelet binding to lymphocytes effectively regulates T lymphocyte function. This mechanism could be easily applied to reduce inflammatory responses.

Measuring inflammation in rheumatoid arthritis with a new clinical and ultrasound index: development and initial validation.

With the aim to develop and validate a clinical + ultrasound (US) inflammation score in rheumatoid arthritis (RA) for use in clinical practice, a mixed-method study was conducted. The theoretical development of the index was achieved with qualitative methodology (discussion group and Delphi survey). Subsequently, a cross-sectional study was carried out to analyse issues related to scoring and validation of the new index. RA patients underwent clinical [28 swollen and tender joints count, patient and physician global assessment (PhGA), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP)], and US assessments [synovitis or tenosynovitis by grey-scale (GS) and power Doppler (PD) of 42 structures]. An index was created based on statistical models and expert interaction. Construct validity was tested by correlation with DAS28, SDAI, CDAI, and PhGA. Reliability was evaluated in a subgroup of patients with the intraclass correlation coefficient (ICC). US assessment, CRP, and swollen joints were the items that passed the prioritization phase (Delphi study). For the cross-sectional study, 281 patients were randomly divided into design (n = 141) and validation samples (n = 140). The combination of US sites chosen (7 bilaterally) detected the maximum proportion of synovitis and PD present. Three scoring methods were tested: semiquantitative (0-3 GS + 0-3 PD), dichotomous (0/1 GS + 0/1 PD), and qualitative (0/1 based on algorithm). All showed strong correlation with activity measures (ρ ≥ 0.60), and reliability (ICC 0.89-0.93). The index with best parameters of validity, feasibility, and reliability was the qualitative. The final index chosen was the sum of swollen joint count, US qualitative score, and CRP. The UltraSound Activity score is a valid and reliable measure of inflammation in RA equal to the sum of 28 SJC, a simplified (0/1) US assessment of 11 structures and CRP. It is necessary further investigation to demonstrate additional value over existing indices.

Association of Platelet Binding to Lymphocytes with B Cell Abnormalities and Clinical Manifestations in Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease associated with the polyclonal activation of B lymphocytes and the production of autoantibodies that cause immune complex-related inflammation. Immunological factors derived from platelets modulate B cell function in SLE disease. However, platelets do not only modify the immune system by soluble factors. The binding of platelets to lymphocytes can modulate immune response. Thus, we speculate that the binding of platelets to lymphocytes in SLE patients may play a role in abnormal B lymphocyte response and the pathogenesis of SLE. We observed that levels of lymphocytes with bound platelets were higher in SLE patients than in healthy donors (HD). In SLE patients, the percentage of B lymphocytes with bound platelets positively correlated with plasmatic levels of IgG, IgA, IL-10, and soluble CD40L and negatively correlated with IgM levels, though not in HD. Preswitched memory B lymphocytes were the subpopulation with more bound platelets. Lymphocytes with bound platelets from both HD and SLE patients had major levels of CD86 and BAFFR and a greater production of IL-10 than lymphocytes without bound platelets. However, only B lymphocytes with bound platelets from SLE patients had increased levels of IgG and IgA on their surface. SLE patients with a suggestive renal manifestation had the highest levels of B and T lymphocytes with bound platelets. These results suggest that the binding of platelets to lymphocytes plays a role in SLE disease and that controlling this binding may be a promising therapeutic approach.

Impact of ultrasonography on treatment decision in rheumatoid arthritis: the IMPULSAR study.

Ultrasonography (US) has shown to be more sensitive than physical examination for diagnosis and assessment of rheumatoid arthritis (RA). It is also a useful approach for accurate monitoring and intensive treatment adjustment. However, there is limited information concerning the impact of US on therapeutic decision-making in routine daily practice. A single-center cross-sectional study in routine daily practice was conducted to determine the percentage of patients with rheumatoid arthritis (RA) in which treatment decision was modified on the basis of results of musculoskeletal ultrasonography. All consecutive patients with RA visited for the control of their disease between September and November 2014 were included. Patients were visited by their attending rheumatologist, who made a therapeutic decision according to the results of physical examination and laboratory tests. Thereafter, a musculoskeletal ultrasound (US) was performed by an independent expert sonographer. According to US findings, a change in therapeutic decision was considered, and categorized as 'negative' (maintenance of the therapeutic attitude) or 'positive' (intensification or reduction of treatment). A total of 78 patients (83% women, mean age 63.3 years) were included. In 29 patients [32%, 95% confidence interval (CI) 26.5-48.9], a change in the therapeutic decision was made, which included intensification of treatment in 18 (62.1%) and reduction of treatment in 11 (37.9%). Change of treatment was more frequent in patients with intermediate disease activity (low and moderate) than in those in clinical remission or with high activity (41.4 vs. 25%), in men than in women (53.8 vs. 33.8%), and in the presence than in the absence of bone erosions (43.6 vs. 21.7%), although differences were not statistically significant. We conclude that in patients with RA, joint US is a relevant complementary tool for treatment decisions in daily practice, particularly in patients with intermediate disease activity.

New medications in development for the treatment of hyperuricemia of gout.

PURPOSE OF REVIEW: To update recent developments in medications targeting hyperuricemia, but not including medications recently labelled in the European Union and the United States. RECENT FINDINGS: A new xanthine oxidase inhibitor, Topiloric (Fujiyakuhin Co., Ltd. Japan) Uriadec (Sanwa Kagaku Kenkyusho Co., Ltd. Japan), has been developed and labelled in Japan. An inhibitor of purine nucleoside phosphorylase, Ulodesine, is in development in combination with allopurinol. The rest of the medications in the pipeline for hyperuricemia are targeting renal transporters of uric acid, mainly URAT1 and OAT4, acting as uricosuric agents. Most of them, such as lesinurad and arhalofenate, are being tested in trials in combination with allopurinol and febuxostat. The most potent RDEA3170 is being tested in monotherapy, but also associated with febuxostat. Recently, medications showing dual activity, inhibiting both xanthine oxidoreductase and URAT1, have been communicated or started exploratory clinical trials. There is no report of medications targeting other transporters such as Glut9 or ABCG2. SUMMARY: There are a number of medications in the pipeline targeting hyperuricemia, mostly uricosurics in combination with xanthine oxidase inhibitors, but some targeting both xanthine oxidoreductase and URAT1. Increasing the number of available medications will ensure proper control of hyperuricemia to target serum urate levels in the near future for most, if not all, patients with hyperuricemia.

A deletion at ADAMTS9-MAGI1 locus is associated with psoriatic arthritis risk.

OBJECTIVE: Copy number variants (CNVs) have been associated with the risk to develop multiple autoimmune diseases. Our objective was to identify CNVs associated with the risk to develop psoriatic arthritis (PsA) using a genome-wide analysis approach. METHODS: A total of 835 patients with PsA and 1498 healthy controls were genotyped for CNVs using the Illumina HumanHap610 BeadChip genotyping platform. Genomic CNVs were characterised using CNstream analysis software and analysed for association using the χ(2) test. The most significant genomic CNV associations with PsA risk were independently tested in a validation sample of 1133 patients with PsA and 1831 healthy controls. In order to test for the specificity of the variants with PsA aetiology, we also analysed the association to a cohort of 822 patients with purely cutaneous psoriasis (PsC). RESULTS: A total of 165 common CNVs were identified in the genome-wide analysis. We found a highly significant association of an intergenic deletion between ADAMTS9 and MAGI1 genes on chromosome 3p14.1 (p=0.00014). Using the independent patient and control cohort, we validated the association between ADAMTS9-MAGI1 deletion and PsA risk (p=0.032). Using next-generation sequencing, we characterised the 26 kb associated deletion. Finally, analysing the PsC cohort we found a lower frequency of the deletion compared with the PsA cohort (p=0.0088) and a similar frequency to that of healthy controls (p>0.3). CONCLUSIONS: The present genome-wide scan for CNVs associated with PsA risk has identified a new deletion associated with disease risk and which is also differential from PsC risk.

Rituximab-induced interleukin-15 reduction associated with clinical improvement in rheumatoid arthritis.

Rituximab therapy alters all aspects of B-cell participation in the disturbed immune response of rheumatoid arthritis patients. To determine the impact of B-cell depletion on other immune compartments, we analysed levels of soluble and surface interleukin-15 (IL-15) along with the frequency of IL-15-related subsets after rituximab treatment. We then studied the correlation of observed changes with clinical activity. Heparinized blood samples from 33 rheumatoid arthritis patients were collected on days 0, 30, 90 and 180 after each of three rituximab cycles. Serum cytokine levels were determined by ELISA. Interleukin-15 trans-presentation was analysed by cytometry. Flow cytometry with monoclonal antibodies was performed to analyse circulating cell subsets. Interleukin-15 was detected in the serum of 25 patients before initiating the treatment. Rituximab then progressively reduced serum IL-15 (138 ± 21 pg/ml at baseline, 48 ± 18 pg/ml after third cycle, P = 0·03) along with IL-17 (1197 ± 203 pg/ml at baseline, 623 ± 213 pg/ml after third cycle, P = 0·03) and tended to increase the frequency of circulating regulatory T cells (3·1 ± 1 cells/µl at baseline, 7·7 ± 2 cells/µl after third cycle). Rituximab also significantly decreased IL-15 trans-presentation on surface monocytes of patients negative for IL-15 serum (mean fluorescence intensity: 4·82 ± 1·30 at baseline, 1·42 ± 0·69 after third cycle P = 0·05). Reduction of serum IL-15 was associated with decrease in CD8(+)  CD45RO(+) /RA(+) ratio (1·17 ± 0·21 at baseline, 0·36 ± 0·06 at third cycle, P = 0·02). DAS28, erythrocyte sedimentation rate and C-reactive protein correlated significantly with CD8(+)  CD45RO(+) /RA(+) ratio (R = 0·323, R = 0·357, R = 0·369 respectively, P < 0·001). Our results suggest that sustained clinical improvement after rituximab treatment is associated with IL-15/memory T-cell-related mechanisms beyond circulating B cells.

The burden of disease in Spain: results from the global burden of disease study 2010.

BACKGROUND: We herein evaluate the Spanish population's trends in health burden by comparing results of two Global Burden of Diseases, Injuries, and Risk Factors Studies (the GBD studies) performed 20 years apart. METHODS: Data is part of the GBD study for 1990 and 2010. We present results for mortality, years of life lost (YLLs), years lived with disability, and disability-adjusted life years (DALYs) for the Spanish population. Uncertainty intervals for all measures have been estimated. RESULTS: Non-communicable diseases accounted for 3,703,400 (95% CI 3,648,270-3,766,720) (91.3%) of 4,057,400 total deaths, in the Spanish population. Cardiovascular and circulatory diseases were the main cause of mortality among non-communicable diseases (34.7% of total deaths), followed by neoplasms (27.1% of total deaths). Neoplasms, cardiovascular and circulatory diseases, and chronic respiratory diseases were the top three leading causes for YLLs. The most important causes of DALYs in 2010 were neoplasms, cardiovascular and circulatory diseases, musculoskeletal disorders, and mental and behavioral disorders. CONCLUSIONS: Mortality and disability in Spain have become even more linked to non-communicable diseases over the last years, following the worldwide trends. Cardiovascular and circulatory diseases, neoplasms, mental and behavioral disorders, and neurological disorders are the leading causes of mortality and disability. Specific focus is needed from health care providers and policy makers to develop health promotion and health education programs directed towards non-communicable disorders.

Concerns of patients with gout are incompletely captured by OMERACT-endorsed domains of measurement for chronic gout studies.

BACKGROUND: Appropriate evaluation of disease or treatment outcomes requires a good understanding of the aspects of the disease and its consequences that actually matter to patients. The OMERACT process has identified several domains of outcome measurement for chronic gout, but patient involvement has only been briefly described. OBJECTIVES: To make the results of patient involvement more explicit, the current study reports on an exercise carried out in the early part of the OMERACT domain identification process. METHODS: Patients with gout were asked to identify areas of life affected by gout. These areas were rated (0-10) and ranked for importance by a second group of patients with gout recruited from both primary care and a rheumatology clinic. RESULTS: Thirty-one patients with gout performed the initial generation of areas of importance. These areas were combined to form 14 items, which were ranked and scored by 107 patients. Four areas were ranked first to third most important by at least 20% of participants. These were pain (median rating, 10), loss of joint motion (median rating, 9), work loss (median rating, 7), and joint inflammation/swelling (median rating, 8). Three additional areas were ranked highly by at least 10% of patients: difficulty with wearing shoes, having to undertake a restrictive diet, and sleep. CONCLUSIONS: These data largely confirmed the relevance of the gout OMERACT domains while identifying additional issues for patients that require further investigation.
