RESUMO

Patients with rheumatoid arthritis (RA) have a 1.5-times excess risk of cardiovascular (CV) disease compared to the general population, attributed to chronic inflammation.1,2 In the general population, detectable levels of high-sensitivity cardiac troponin (hs-cTn) are associated with higher risk of major adverse CV events (MACE) and all-cause mortality.3.

RESUMO

BACKGROUND: Coronary microvascular dysfunction as measured by myocardial flow reserve (MFR) is associated with increased cardiovascular risk in rheumatoid arthritis (RA). The objective of this study was to determine the association between reducing inflammation with MFR and other measures of cardiovascular risk. METHODS AND RESULTS: Patients with RA with active disease about to initiate a tumor necrosis factor inhibitor were enrolled (NCT02714881). All subjects underwent a cardiac perfusion positron emission tomography scan to quantify MFR at baseline before tumor necrosis factor inhibitor initiation, and after tumor necrosis factor inhibitor initiation at 24 weeks. MFR <2.5 in the absence of obstructive coronary artery disease was defined as coronary microvascular dysfunction. Blood samples at baseline and 24 weeks were measured for inflammatory markers (eg, high-sensitivity C-reactive protein [hsCRP], interleukin-1b, and high-sensitivity cardiac troponin T [hs-cTnT]). The primary outcome was mean MFR before and after tumor necrosis factor inhibitor initiation, with Δhs-cTnT as the secondary outcome. Secondary and exploratory analyses included the correlation between ΔhsCRP and other inflammatory markers with MFR and hs-cTnT. We studied 66 subjects, 82% of which were women, mean RA duration 7.4 years. The median atherosclerotic cardiovascular disease risk was 2.5%; 47% had coronary microvascular dysfunction and 23% had detectable hs-cTnT. We observed no change in mean MFR before (2.65) and after treatment (2.64, P=0.6) or hs-cTnT. A correlation was observed between a reduction in hsCRP and interleukin-1b with a reduction in hs-cTnT. CONCLUSIONS: In this RA cohort with low prevalence of cardiovascular risk factors, nearly 50% of subjects had coronary microvascular dysfunction at baseline. A reduction in inflammation was not associated with improved MFR. However, a modest reduction in interleukin-1b and no other inflammatory pathways was correlated with a reduction in subclinical myocardial injury.

RESUMO

OBJECTIVE: Switching biologic and targeted synthetic DMARD (b/tsDMARD) medications occurs commonly in RA patients, however data are limited on the reasons for these changes. The objective of the study was to identify and categorize reasons for b/tsDMARD switching and investigate characteristics associated with treatment refractory RA. METHODS: In a multi-hospital RA electronic health record (EHR) cohort, we identified RA patients prescribed ≥1 b/tsDMARD between 2001 and 2017. Consistent with the EULAR "difficult to treat" (D2T) RA definition, we further identified patients who discontinued ≥2 b/tsDMARDs with different mechanisms of action. We performed manual chart review to determine reasons for medication discontinuation. We defined "treatment refractory" RA as not achieving low disease activity (<3 tender or swollen joints on <7.5 mg of daily prednisone equivalent) despite treatment with two different b/tsDMARD mechanisms of action. We compared demographic, lifestyle, and clinical factors between treatment refractory RA and b/tsDMARD initiators not meeting D2T criteria. RESULTS: We identified 6040 RA patients prescribed ≥1 b/tsDMARD including 404 meeting D2T criteria. The most common reasons for medication discontinuation were inadequate response (43.3 %), loss of efficacy (25.8 %), and non-allergic adverse events (13.7 %). Of patients with D2T RA, 15 % had treatment refractory RA. Treatment refractory RA patients were younger at b/tsDMARD initiation (mean 47.2 vs. 55.2 years, p < 0.001), more commonly female (91.8% vs. 76.1 %, p = 0.006), and ever smokers (68.9% vs. 49.9 %, p = 0.005). No RA clinical factors differentiated treatment refractory RA patients from b/tsDMARD initiators. CONCLUSIONS: In a large EHR-based RA cohort, the most common reasons for b/tsDMARD switching were inadequate response, loss of efficacy, and nonallergic adverse events (e.g. infections, leukopenia, psoriasis). Clinical RA factors were insufficient for differentiating b/tsDMARD responders from nonresponders.

RESUMO

BACKGROUND: Many patients with rheumatoid arthritis (RA) require a trial of multiple biologic disease-modifying anti-rheumatic drugs (bDMARDs) to control their disease. With the availability of several bDMARD options, the history of bDMARDs may provide an alternative approach to understanding subphenotypes of RA. The objective of this study was to determine whether there exist distinct clusters of RA patients based on bDMARD prescription history to subphenotype RA. METHODS: We studied patients from a validated electronic health record-based RA cohort with data from January 1, 2008, through July 31, 2019; all subjects prescribed ≥ 1 bDMARD or targeted synthetic (ts) DMARD were included. To determine whether subjects had similar b/tsDMARD sequences, the sequences were considered as a Markov chain over the state-space of 5 classes of b/tsDMARDs. The maximum likelihood estimator (MLE)-based approach was used to estimate the Markov chain parameters to determine the clusters. The EHR data of study subjects were further linked with a registry containing prospectively collected data for RA disease activity, i.e., clinical disease activity index (CDAI). As a proof of concept, we tested whether the clusters derived from b/tsDMARD sequences correlated with clinical measures, specifically differing trajectories of CDAI. RESULTS: We studied 2172 RA subjects, mean age 52 years, RA duration 3.4 years, and 62% seropositive. We observed 550 unique b/tsDMARD sequences and identified 4 main clusters: (1) TNFi persisters (65.7%), (2) TNFi and abatacept therapy (8.0%), (3) on rituximab or multiple b/tsDMARDs (12.7%), (4) prescribed multiple therapies with tocilizumab predominant (13.6%). Compared to the other groups, TNFi persisters had the most favorable trajectory of CDAI over time. CONCLUSION: We observed that RA subjects can be clustered based on the sequence of b/tsDMARD prescriptions over time and that the clusters were correlated with differing trajectories of disease activity over time. This study highlights an alternative approach to consider subphenotyping of patients with RA for studies aimed at understanding treatment response.

RESUMO

T cell-derived pro-inflammatory cytokines are a major driver of rheumatoid arthritis (RA) pathogenesis. Although these cytokines have traditionally been attributed to CD4 T cells, we have found that CD8 T cells are notably abundant in synovium and make more interferon (IFN)-γ and nearly as much tumor necrosis factor (TNF) as their CD4 T cell counterparts. Furthermore, using unbiased high-dimensional single-cell RNA-seq and flow cytometric data, we found that the vast majority of synovial tissue and synovial fluid CD8 T cells belong to an effector CD8 T cell population characterized by high expression of granzyme K (GzmK) and low expression of granzyme B (GzmB) and perforin. Functional experiments demonstrate that these GzmK+ GzmB+ CD8 T cells are major cytokine producers with low cytotoxic potential. Using T cell receptor repertoire data, we found that CD8 GzmK+ GzmB+ T cells are clonally expanded in synovial tissues and maintain their granzyme expression and overall cell state in blood, suggesting that they are enriched in tissue but also circulate. Using GzmK and GzmB signatures, we found that GzmK-expressing CD8 T cells were also the major CD8 T cell population in the gut, kidney, and coronavirus disease 2019 (COVID-19) bronchoalveolar lavage fluid, suggesting that they form a core population of tissue-associated T cells across diseases and human tissues. We term this population tissue-enriched expressing GzmK or TteK CD8 cells. Armed to produce cytokines in response to both antigen-dependent and antigen-independent stimuli, CD8 TteK cells have the potential to drive inflammation.

RESUMO

OBJECTIVE: Systemic rheumatic conditions affect reproductive-aged patients and often require potentially teratogenic medications. We assessed the feasibility and impact of a standardized pregnancy intention screening question (One Key Question [OKQ]) in a large academic rheumatology practice. METHODS: This 6-month pilot quality improvement initiative prompted rheumatologists to ask female patients aged 18 to 49 years about their pregnancy intentions using OKQ. We administered surveys to assess rheumatologists' barriers to and comfort with reproductive health issues. We performed chart reviews to assess uptake and impact on documentation, comparing charts with OKQ documented with 100 randomly selected charts eligible for pregnancy intention screening but without OKQ documented. RESULTS: When we compared 32 of 43 preimplementation responses with 29 of 41 postimplementation responses, the proportion of rheumatologists who reported they were very comfortable with assessing their patients' reproductive goals increased (31%-38%) and the proportion reporting obstetrics and gynecology (OB/GYN) referral challenges as barriers to discussing reproductive goals decreased (41%-21%). During the implementation period, 83 of 957 (9%) eligible patients had OKQ documented in their chart. Female providers were more likely to screen than male providers (odds ratio 2.42, 95% confidence interval 1.21-4.85). Screened patients were more likely to have their contraceptive method documented (P < 0.001) and more likely to have been referred to OB/GYN for follow-up (P = 0.003) compared with patients who were not screened with OKQ. CONCLUSION: Although uptake was low, this tool improved provider comfort with assessing reproductive goals, the quality of documentation, and the likelihood of OB/GYN referral. Future studies should examine whether automated medical record alerts to prompt screening increase uptake.

RESUMO

Macrophages regulate protective immune responses to infectious microbes, but aberrant macrophage activation frequently drives pathological inflammation. To identify regulators of vigorous macrophage activation, we analyzed RNA-seq data from synovial macrophages and identified SLAMF7 as a receptor associated with a superactivated macrophage state in rheumatoid arthritis. We implicated IFN-γ as a key regulator of SLAMF7 expression and engaging SLAMF7 drove a strong wave of inflammatory cytokine expression. Induction of TNF-α after SLAMF7 engagement amplified inflammation through an autocrine signaling loop. We observed SLAMF7-induced gene programs not only in macrophages from rheumatoid arthritis patients but also in gut macrophages from patients with active Crohn's disease and in lung macrophages from patients with severe COVID-19. This suggests a central role for SLAMF7 in macrophage superactivation with broad implications in human disease pathology.

RESUMO

OBJECTIVE: Patients with rheumatoid arthritis (RA) are 1.5 times more likely to develop cardiovascular disease (CVD) attributed to chronic inflammation. A decrease in inflammation in patients with RA is associated with increased low-density lipoprotein (LDL) cholesterol. This study was undertaken to prospectively evaluate the changes in lipid levels among RA patients experiencing changes in inflammation and determine the association with concomitant temporal patterns in markers of myocardial injury. METHODS: A total of 196 patients were evaluated in a longitudinal RA cohort, with blood samples and high-sensitivity C-reactive protein (hsCRP) levels measured annually. Patients were stratified based on whether they experienced either a significant increase in inflammation (an increase in hsCRP of ≥10 mg/liter between any 2 time points 1 year apart; designated the increased inflammation cohort [n = 103]) or decrease in inflammation (a decrease in hsCRP of ≥10 mg/liter between any 2 time points 1 year apart; designated the decreased inflammation cohort [n = 93]). Routine and advanced lipids, markers of inflammation (interleukin-6, hsCRP, soluble tumor necrosis factor receptor II), and markers of subclinical myocardial injury (high-sensitivity cardiac troponin T [hs-cTnT], N-terminal pro-brain natriuretic peptide) were measured. RESULTS: Among the patients in the increased inflammation cohort, the mean age was 59 years, 81% were women, and the mean RA disease duration was 17.9 years. The average increase in hsCRP levels was 36 mg/liter, and this increase was associated with significant reductions in LDL cholesterol, triglycerides, total cholesterol, apolipoprotein (Apo B), and Apo A-I levels. In the increased inflammation cohort at baseline, 45.6% of patients (47 of 103) had detectable circulating hs-cTnT, which further increased during inflammation (P = 0.02). In the decreased inflammation cohort, hs-cTnT levels remained stable despite a reduction in inflammation over follow-up. In both cohorts, hs-cTnT levels were associated with the overall estimated risk of CVD. CONCLUSION: Among RA patients who experienced an increase in inflammation, a significant decrease in routinely measured lipids, including LDL cholesterol, and an increase in markers of subclinical myocardial injury were observed. These findings highlight the divergence in biomarkers of CVD risk and suggest a role in future studies examining the benefit of including hs-cTnT for CVD risk stratification in RA.

RESUMO

OBJECTIVE: Lifestyle factors, such as inactivity and obesity, contribute to cognitive decline in the general population, but little is known about how these factors may affect individuals with a chronic inflammatory condition such as rheumatoid arthritis (RA). We studied the clinical and functional risk factors related to a worsening of perceived cognitive function in patients with RA. METHODS: We collected clinical and functional questionnaire data over 10 years in a prospective RA cohort including yearly self-reported memory, concentration, and word-finding difficulties graded from "never" to "often." Generalized estimating equation models examined the role of exercise (defined as those meeting the Department of Health and Human Services physical activity guidelines of 75 minutes of vigorous or 150 minutes of moderate aerobic activity per week), body mass index (BMI), sleep, depression (Mental Health Index-Depression), Disease Activity Score (DAS)28-c-reactive protein (CRP)3 score, disease-modifying antirheumatic drug, and corticosteroid use from the previous year as predictors of cognitive complaints that progressed to "often" compared with the previous year (the first year (T i ) progressed to "often" 1 year later (T i+1)). RESULTS: Of 1219 RA subjects, 127 (10.4%) described either poor memory, concentration, or word-finding difficulties as affecting them "often" at study entry. RA patients (n = 1092, mean age = 56.5 years, 82% female, 58% college educated) were less likely to report word-finding difficulties, poor memory, and concentration as "often" if they were physically active (p = 0.0001, P = 0.01, P < 0.0001, respectively). Female RA patients developed more concentration complaints compared with males (P = 0.03); patients taking an anti-tumor necrosis factor therapy were less likely to complain of poor memory (P = 0.01). Sleep, BMI, fatigue, depression, DAS28-CRP3, methotrexate, and corticosteroid use were not independently associated with a worsening of any cognitive complaints. CONCLUSION: RA patients who are physically active are less likely to report cognitive difficulties. Our study suggests potential modifiable risk factors for the prevention of cognitive dysfunction in RA.

RESUMO

OBJECTIVE: We aimed to investigate the musculoskeletal and pulmonary outcomes of patients with osseous sarcoidosis. METHODS: We identified 24 patients with osseous sarcoidosis and at least one year of follow-up after diagnosis (baseline). We collected outcome data at 1-year follow-up and last follow-up. We defined a composite outcome measure; worsening considered as worsening in any of the following 4 components compared to baseline: 1) osseous sarcoidosis symptoms, 2) musculoskeletal imaging of affected bone, 3) chest imaging, or 4) pulmonary function testing (PFT). RESULTS: A minority of patients had a worsening composite outcome at 1-year (9/24, 38%) and last follow-up (5/24, 21%). When only considering musculoskeletal symptoms and imaging, only 25% (6/24) and 13% (3/24) of patients worsened compared to baseline at 1-year and last follow-up, respectively. Patients with a worsening composite overall outcome tended to be older at baseline than those without the outcome for both 1-year (54.3 years vs. 47.5 years, p=0.11) and last follow-up (55.0 years vs. 48.7 years; p=0.23), although these differences were non-significant. Treatment was not associated with worsening composite overall outcome at 1-year follow-up (p=0.40), but was significantly associated with decreased risk for worsening at last follow-up (p=0.05). CONCLUSIONS: In this retrospective cohort study of osseous sarcoidosis, most patients had a favorable outcome according to symptoms, musculoskeletal/chest imaging, and PFTs, even though only a minority were treated with glucocorticoids or DMARDs. These results suggest that the natural history of osseous sarcoidosis is often benign, although some patients experience clinical progression.

RESUMO

High-dimensional single-cell analyses have improved the ability to resolve complex mixtures of cells from human disease samples; however, identifying disease-associated cell types or cell states in patient samples remains challenging because of technical and interindividual variation. Here, we present mixed-effects modeling of associations of single cells (MASC), a reverse single-cell association strategy for testing whether case-control status influences the membership of single cells in any of multiple cellular subsets while accounting for technical confounders and biological variation. Applying MASC to mass cytometry analyses of CD4+ T cells from the blood of rheumatoid arthritis (RA) patients and controls revealed a significantly expanded population of CD4+ T cells, identified as CD27- HLA-DR+ effector memory cells, in RA patients (odds ratio, 1.7; P = 1.1 × 10-3). The frequency of CD27- HLA-DR+ cells was similarly elevated in blood samples from a second RA patient cohort, and CD27- HLA-DR+ cell frequency decreased in RA patients who responded to immunosuppressive therapy. Mass cytometry and flow cytometry analyses indicated that CD27- HLA-DR+ cells were associated with RA (meta-analysis P = 2.3 × 10-4). Compared to peripheral blood, synovial fluid and synovial tissue samples from RA patients contained about fivefold higher frequencies of CD27- HLA-DR+ cells, which comprised ~10% of synovial CD4+ T cells. CD27- HLA-DR+ cells expressed a distinctive effector memory transcriptomic program with T helper 1 (TH1)- and cytotoxicity-associated features and produced abundant interferon-γ (IFN-γ) and granzyme A protein upon stimulation. We propose that MASC is a broadly applicable method to identify disease-associated cell populations in high-dimensional single-cell data.

RESUMO

OBJECTIVE: Current validated cardiovascular (CV) risk estimates were developed in populations with relatively stable levels of inflammation, whereas patients with rheumatoid arthritis (RA) routinely experience significant changes in inflammation. This study was undertaken to test whether changes in inflammation affect estimated CV risk as measured using validated population-based risk calculators. METHODS: Participants in a prospective RA cohort who experienced a decrease or an increase of ≥10 mg/liter in the C-reactive protein (CRP) level at 2 consecutive time points 1 year apart (CRP decrease group and CRP increase group, respectively) were included in this study. We estimated 10-year CV risk using the following calculators: Framingham Risk Score, 2013 American College of Cardiology/American Heart Association Atherosclerotic Cardiovascular Disease Risk Score, Reynolds Risk Score (RRS), and QRISK2. Of these calculators, only the RRS includes a variable addressing the CRP level. Paired t-tests were performed to compare risk scores at baseline and 1-year follow-up. We calculated the correlations between the changes in risk scores and changes in pro-B-type natriuretic peptide (pro BNP), a surrogate marker of CV risk. RESULTS: One hundred eighty RA patients were included in the study (mean age 57.8 years, 84% female, 80% seropositive). Of the calculators studied, only the RRS was sensitive to changes in inflammation; an increase in inflammation was associated with increased estimated CV risk (P < 0.0001), and only the RRS was correlated with changes in proBNP (r = 0.17, P = 0.03). CONCLUSION: Our data showed no significant change in CV risk estimated using validated general population CV risk calculators except for the RRS. These findings suggest that CV risk may be modulated by changes in inflammation in RA, which is not typically considered when using existing CV risk calculators.

RESUMO

CD4+ T cells are central mediators of autoimmune pathology; however, defining their key effector functions in specific autoimmune diseases remains challenging. Pathogenic CD4+ T cells within affected tissues may be identified by expression of markers of recent activation. Here we use mass cytometry to analyse activated T cells in joint tissue from patients with rheumatoid arthritis, a chronic immune-mediated arthritis that affects up to 1% of the population. This approach revealed a markedly expanded population of PD-1hiCXCR5-CD4+ T cells in synovium of patients with rheumatoid arthritis. However, these cells are not exhausted, despite high PD-1 expression. Rather, using multidimensional cytometry, transcriptomics, and functional assays, we define a population of PD-1hiCXCR5- 'peripheral helper' T (TPH) cells that express factors enabling B-cell help, including IL-21, CXCL13, ICOS, and MAF. Like PD-1hiCXCR5+ T follicular helper cells, TPH cells induce plasma cell differentiation in vitro through IL-21 secretion and SLAMF5 interaction (refs 3, 4). However, global transcriptomics highlight differences between TPH cells and T follicular helper cells, including altered expression of BCL6 and BLIMP1 and unique expression of chemokine receptors that direct migration to inflamed sites, such as CCR2, CX3CR1, and CCR5, in TPH cells. TPH cells appear to be uniquely poised to promote B-cell responses and antibody production within pathologically inflamed non-lymphoid tissues.

RESUMO

OBJECTIVE: Previous cross-sectional studies have shown that rheumatoid arthritis (RA) patients with fibromyalgia (FM) have higher disease activity, greater medical costs, and worse quality of life compared to RA patients without FM. We determined the impact of FM on 2-year changes in the functional status of RA patients in a prospective study. METHODS: Subjects included participants in the Brigham Rheumatoid Arthritis Sequential Study who were enrolled in a substudy of the effects of pain in RA. Subjects completed questionnaires, including the Multi-Dimensional Health Assessment Questionnaire (MDHAQ) and Polysymptomatic Distress (PSD) scale, semiannually, and underwent physical examination and laboratory tests yearly. RESULTS: Of the 156 included RA subjects, 16.7% had FM, while 83.3% did not. In a multivariable linear regression model adjusted for age, sex, race, baseline MDHAQ score, disease duration, rheumatoid factor/cyclic citrullinated peptide antibody seropositivity, disease activity, and psychological distress, RA patients with FM had a 0.14 greater 2-year increase in MDHAQ score than RA patients without FM (P = 0.021). In secondary analyses examining the association between continuous PSD scale score and change in MDHAQ, higher PSD scale scores were significantly associated with greater 2-year increases in MDHAQ score (ß coefficient 0.013, P = 0.011). CONCLUSION: Both the presence of FM and increasing number of FM symptoms predicted worsening of functional status among individuals with RA. Among individuals with RA and FM, the magnitude of the difference in changes in MDHAQ was 4- to 7-fold higher than typical changes in MDHAQ score among individuals with established RA.

RESUMO

BACKGROUND: Incomplete medication reconciliation has been identified as a source of adverse drug events and a threat to patient safety. How best to measure and improve rates of medication reconciliation in ambulatory care remains unknown. METHODS: An institutional collaborative improvement effort to develop and implement medication reconciliation processes was designed and facilitated across all 148 Brigham and Women's Hospital (Boston) ambulatory specialty practices: 63 underwent a more rigorous approach, a modified approach was undertaken in another 71 specialty practices, and a less intensive approach took place in the 14 primary care practices. The level of intervention varied on the basis of preexisting improvement infrastructure and practice prescription rates. Two electronically measured metrics were created to evaluate ambulatory visits to a provider in which there was a medication change: (1) Measure 1: the percentage of active medications prescribed by that provider that were reconciled; and (2) Measure 2: how often all the medications prescribed by that provider were reconciled. After the collaborative was completed, performance data were routinely shared with frontline staff and hospital leadership, and medication reconciliation rates became part of an institutional financial incentive program. RESULTS: For Measure 1, specialty practices improved from 71% to 90% (September 2012-August 2014; 24-month period). Primary care practice performance improved from 62% to 91% (December 2012-August 2014; 20-month period). For Measure 2, overall performance across all ambulatory practices increased from 81% to 90% during the first 12 months of the financial incentive program (October 2013- September 2014). CONCLUSION: A collaborative model of process improvement paired with financial incentives can successfully increase rates of ambulatory medication reconciliation.

RESUMO

Background. Influenza and pneumococcal vaccinations are recommended for elderly and high-risk patients; however, rates of adherence are low. We sought to implement influenza and pneumococcal vaccine initiatives in 4 different ambulatory specialty practices, using 3 unique approaches. Methods. Four specialties with high-risk patient populations were selected for intervention: allergy (asthma), infectious disease (ID) (human immunodeficiency virus), pulmonary (chronic lung disease), and rheumatology (immunocompromised). Allergy and ID focused on influenza vaccination, and pulmonary and rheumatology focused on pneumococcal vaccination. We used 3 strategies for quality improvement: physician reminders, patient letters, and a nurse-driven model. Physicians were provided their performance data on a monthly basis and presented trended data on a quarterly basis at staff meetings. Results. All 4 specialties developed processes for improving vaccination rates with all showing some increase. Higher rates were achieved with pneumococcal vaccine than influenza. Pneumococcal vaccine rates showed steady improvement from year to year while influenza vaccine rates remained relatively constant. Allergy's influenza rate was 59% in 2011 and 64% in the 2014 flu season. Infectious disease influenza rates moved from 74% in the 2011 flu season to 86% for the 2014 season. Pneumococcal vaccine in pulmonary patients' rate was 52% at the start of intervention in February 2009 and 79% as of January 2015. Rheumatology rates rose from 50% in February 2009 to 87% in January 2015. Conclusions. Integrated routine workflow and performance data sharing can effectively engage specialists and staff in vaccine adherence improvement. Influenza vaccination may require other approaches to achieve the rates seen with pneumococcal vaccine.

RESUMO

BACKGROUND: Potent anti-inflammatory rheumatoid arthritis (RA) treatments are associated with reduced cardiovascular risk as well as increases in low-density lipoprotein (LDL) cholesterol. This apparent paradox may be explained by favorable changes in other lipid measurements. The objective of this study was to determine the longitudinal association between changes in inflammation with advanced lipoprotein measurements and high-density lipoprotein (HDL) cholesterol efflux capacity. METHODS AND RESULTS: We conducted this study in a longitudinal RA cohort from a large academic center, including subjects with high-sensitivity C-reactive protein (hs-CRP) reduction ≥10 mg/L at 2 time points 1 year apart. Subjects receiving statins during the study period or preceding 6 months were excluded. We compared total cholesterol, LDL cholesterol, HDL cholesterol, apolipoprotein B, and apolipoprotein A1 levels and HDL cholesterol efflux capacity at baseline and 1-year follow-up by using the paired t test. We also assessed the correlations between reductions in hs-CRP with percentage change in lipid parameters. We studied 90 RA subjects (mean age 57 years, 89% female), all of whom were receiving disease-modifying antirheumatic drugs. We observed a 7.2% increase in LDL cholesterol levels (P=0.02) and improvement in efflux capacity by 5.7% (P=0.002) between baseline and follow-up, with a median hs-CRP reduction of 23.5 mg/L. We observed significant correlations between reductions in hs-CRP with increases in apolipoprotein A1 (r=0.27, P=0.01) and HDL cholesterol efflux capacity (r=0.24, P=0.02). CONCLUSION: Among RA subjects experiencing reductions in hs-CRP, we observed increased LDL cholesterol levels and concomitant improvements in HDL cholesterol efflux capacity. These findings provide further insight into lipid modulation and the beneficial effect of reduction in inflammation on lipids in vivo.

RESUMO

OBJECTIVE: Osseous sarcoidosis has been infrequently reported. We aimed to characterize the distribution of lesions, clinical presentation, treatment, and outcomes for osseous sarcoidosis. METHODS: Cases of osseous sarcoidosis were identified by directed inquiry to clinicians and electronic query. Cases were defined as having pathologic evidence of non-caseating granulomas on bone biopsy or evidence of osseous lesions on imaging attributable to sarcoidosis in patients with known sarcoidosis. Detailed characteristics were obtained by medical record review. RESULTS: We identified a total of 20 cases of osseous sarcoidosis. Osseous lesions were detected by imaging during the initial sarcoidosis presentation in 60% of cases. In those who had a prior diagnosis of sarcoidosis, the median duration of sarcoidosis before detection of osseous involvement was 4.3 years. Symptoms were present in 50% of cases. All cases had more than one bone involved. The axial skeleton was involved in the majority of cases (90%), primarily the pelvis and the lumbar spine. Most cases required no treatment (55%); a minority of cases (45%) were treated, most often with prednisone, methotrexate, or hydroxychloroquine. Two cases required multiple immunosuppressants, including tumor necrosis factor inhibitors, for refractory symptomatic osseous sarcoidosis. Treated cases were younger than those who were untreated. At last follow-up, most cases (85%) were asymptomatic from osseous lesions. CONCLUSIONS: In this case series of osseous sarcoidosis from a single center, most patients had multiple bones affected and had other systemic manifestations of sarcoidosis. A minority required treatment for relief of symptoms, and most cases were asymptomatic at last follow-up.

RESUMO

OBJECTIVE: Documentation of quality measures (QMs) in rheumatoid arthritis (RA) is used as a surrogate for measure of quality of care, but the association of this documentation with radiographic outcomes is uncertain. We examined documentation of RA QMs, for disease activity and functional status and the association with radiographic outcomes. METHODS: Data were analyzed for 438 RA patients in a longitudinal cohort with complete data on van der Heijde-modified Total Sharp Score (TSS). All rheumatologist (N = 18) notes in the electronic medical record during a 24-month period were reviewed for RA QMs. Any mention of disease activity categorized as low, moderate, or high was considered documentation of the QM for disease activity. Functional status QM documentation included any mention of the impact of RA on function. Change in TSS was quantified with progression defined as ≥1 unit per year. We compared percent of visits with an RA QM documented and mean change in TSS. RESULTS: The mean age in the cohort was 56.9 years, disease duration was 10.8 years, baseline DAS28 score was 3.8 (±1.6), 67.7% were seropositive, and 33.9% used a biologic DMARD. Radiographic progression was observed in 28.5%. Disease activity was documented for 29.0% of patient visits and functional status in 74.7%; neither had any significant relationship to mean TSS change (both P > 0.10). CONCLUSION: The documentation of RA QMs was infrequent and not associated with radiographic outcomes over 24 months.
