In the United States, approximately 35% of adults with Systemic Lupus Erythematosus (SLE) have clinical evidence of nephritis at the time of diagnosis; with an estimated total of 50–60% developing nephritis during the first 10 years of disease [1–4]. The prevalence of nephritis is significantly higher in African Americans and Hispanics than in Caucasians, and is higher in men than in women. Renal damage is more likely to develop in non-Caucasian groups [2–4]. Overall survival in patients with SLE is approximately 95% at 5 years after diagnosis and 92% at 10 years [5, 6]. The presence of lupus nephritis significantly reduces survival, to approximately 88% at 10 years, with even lower survival in African Americans [5, 6]. The American College of Rheumatology (ACR) last published guidelines for management of systemic lupus erythematosus (SLE) in 1999 [7]. That publication was designed primarily for education of primary care physicians and recommended therapeutic and management approaches for many manifestations of SLE. Recommendations for management of lupus nephritis (LN) consisted of pulse glucocorticoids followed by high dose daily glucocorticoids in addition to an immunosuppressive medication, with cyclophosphamide viewed as the most effective immunosuppressive medication for diffuse proliferative glomerulonephritis. Mycophenolate mofetil was not yet in use for lupus nephritis and was not mentioned. Since that time, many clinical trials of glucocorticoids-plus-immunosuppressive interventions have been published, some of which are high quality prospective trials, and some not only prospective but also randomized. Thus, the ACR determined that a new set of management recommendations was in order. A combination of extensive literature review and the opinions of highly qualified experts, including rheumatologists, nephrologists and pathologists, has been used to reach the recommendations. The management strategies discussed here apply to lupus nephritis in adults, particularly to those receiving care in the United States of America, and include interventions that were available in the United States as of April 2011. While these recommendations were developed using rigorous methodology, guidelines do have inherent limitations in informing individual patient care; hence the selection of the term “recommendations.” While they should not supplant clinical judgment or limit clinical judgment, they do provide expert advice to the practicing physician managing patients with lupus nephritis.

In response to a request for proposal from the American College of Rheumatology (ACR), our group was charged with developing non-pharmacologic and pharmacologic guidelines for treatments in gout that are safe and effective, i.e., with acceptable risk-benefit ratio. These guidelines for the management and anti-inflammatory prophylaxis of acute attacks of gouty arthritis complements our manuscript on guidelines to treat hyperuricemia in patients with evidence of gout (or gouty arthritis) (1). Gout is the most common cause of inflammatory arthritis in adults in the USA. Clinical manifestations in joints and bursa are superimposed on top of local deposition of monosodium urate crystals. Acute gout characteristically presents as self-limited, attack of synovitis (also called “gout flares”). Acute gout attacks account for a major component of the reported decreased health-related quality of life in patients with gout (2, 3). Acute gout attacks can be debilitating and are associated with decreased work productivity (4, 5). Urate lowering therapy (ULT) is a cornerstone in the management of gout, and, when effective in lowering serum urate (SUA), is associated with decreased risk of acute gouty attacks (6). However, during the initial phase of ULT, there is an early increase in acute gout attacks, which has been hypothesized due to remodeling of articular urate crystal deposits as a result of rapid and substantial lowering of ambient urate concentrations (7). Acute gout attacks attributable to the initiation of ULT may contribute to non-adherence in long-term gout treatment, as reported in recent studies (8). In order to systematically evaluate a broad spectrum of acute gouty arthritis, we generated multifaceted case scenarios to elucidate decision making based primarily on clinical and laboratory test-based data that can be obtained in a gout patient by both non-specialist and specialist health care providers in an office practice setting. This effort was not intended to create a novel classification system of gout, or new gout diagnostic criteria, as such endeavors are beyond the scope of this work. Prior gout recommendations and guidelines, at the independent (i.e, non pharmaceutical industry-sponsored) national or multinational rheumatology society level, have been published by EULAR (9, 10), the Dutch College of General Practitioners (11), and the British Society for Rheumatology (BSR)(12). The ACR requested new guidelines, in view of the increasing prevalence of gout (13), the clinical complexity of management of gouty arthritis imposed by co-morbidities common in gout patients (14), and increasing numbers of treatment options via clinical development of agents(15–17). The ACR charged us to develop these guidelines to be useful for both rheumatologists and other health care providers on an international level. As such, this process and resultant recommendations, involved a diverse and international panel of experts. In this manuscript, we concentrate on 2 of the 4 gout domains that the ACR requested for evaluation of pharmacologic and non-pharmacologic management approaches: (i) analgesic and anti-inflammatory management of acute attacks of gouty arthritis, and (ii) pharmacologic anti-inflammatory prophylaxis of acute attacks of gouty arthritis. Part I of the guidelines focused on systematic non-pharmacologic measures (patient education, diet and lifestyle choices, identification and management of co-morbidities) that impact on hyperuricemia, and made recommendations on pharmacologic ULT in a broad range of case scenarios of patients with disease activity manifested by acute and chronic forms of gouty arthritis, including chronic tophaceous gouty arthropathy(1). Each individual and specific statement is designated as a “recommendation”, in order to reflect the non-prescriptive nature of decision making for the hypothetical clinical scenarios. So that the voting panel could focus on gout treatment decisions, a number of key assumptions were made, as described in Part I of the guidelines (1). Importantly, each proposed recommendation assumed that correct diagnoses of gout and acute gouty arthritis attacks had been made for the voting scenario in question. For treatment purposes, it was also assumed that treating clinicians were competent, and considered underlying medical comorbidities (including diabetes, gastrointestinal disease, hypertension, and hepatic, cardiac, and renal disease), and potential drug toxicities and drug-drug interactions, when making both treatment choicesand dosing decisions on chosen pharmacologic interventions. The RAND/UCLA methodology used here emphasizes level of evidence, safety, and quality of therapy, and excludes analyses of societal cost of health care. As such, the ACR gout guidelines are designed to reflect best practice, supported either by level of evidence or consensus-based decision-making. These guidelines cannot substitute for individualized, direct assessment of the patient, coupled with clinical decision making by a competent health care practitioner. The motivation, financial circumstances, and preferences of the gout patient also need to be considered in clinical practice, and it is incumbent on the treating clinician to weigh the issues not addressed by this methodology, such as treatment costs, when making management decisions. Last, the guidelines for gout management presented herein were not designed to determine eligibility for health care cost coverage by third party payers.

OBJECTIVE Women with systemic lupus erythematosus (SLE) have an increased risk of atherosclerosis. Identification of at-risk patients and the etiology underlying atherosclerosis in SLE remain elusive. The antioxidant capacity of normal high-density lipoproteins (HDLs) is lost during inflammation, and these dysfunctional HDLs might predispose individuals to atherosclerosis. The aim of this study was to determine whether dysfunctional proinflammatory HDL (piHDL) is associated with subclinical atherosclerosis in SLE. METHODS Carotid artery ultrasound was performed in 276 women with SLE to identify carotid plaques and measure intima-media thickness (IMT). The antioxidant function of HDL was measured as the change in oxidation of low-density lipoprotein after the addition of HDL cholesterol. Two antiinflammatory HDL components, paraoxonase 1 and apolipoprotein A-I, were also measured. RESULTS Among the SLE patients, 48.2% were determined to have piHDL on carotid ultrasound, while 86.7% of patients with plaque had piHDL compared with 40.7% of those without plaque (P<0.001). Patients with piHDL also had a higher IMT (P<0.001). After multivariate analysis, the only factors found to be significantly associated with plaque were the presence of piHDL (odds ratio [OR] 16.1, P<0.001), older age (OR 1.2, P<0.001), hypertension (OR 3.0, P=0.04), dyslipidemia (OR 3.4, P=0.04), and mixed racial background (OR 8.3, P=0.04). Factors associated with IMT measurements in the highest quartile were the presence of piHDL (OR 2.5, P=0.02), older age (OR 1.1, P<0.001), a higher body mass index (OR 1.07, P=0.04), a cumulative lifetime prednisone dose>or=20 gm (OR 2.9, P=0.04), and African American race (OR 8.3, P=0.001). CONCLUSION Dysfunctional piHDL greatly increases the risk of developing subclinical atherosclerosis in SLE. The presence of piHDL was associated with an increased prevalence of carotid plaque and with a higher IMT. Therefore, determination of piHDL may help identify patients at risk for atherosclerosis.

STUDY OBJECTIVES Disturbances of sleep are hypothesized to contribute to pain. However, experimental data are limited to healthy pain-free individuals. This study evaluated the effect of sleep loss during part of the night on daytime mood symptoms and pain perceptions in patients with rheumatoid arthritis in comparison with control subjects. DESIGN A between-groups laboratory study with assessment of mood symptoms and pain perception before and after partial night sleep deprivation (PSD; awake 23:00 hr to 03:00 hr). SETTING General clinical research center. PARTICIPANTS Patients with rheumatoid arthritis (n = 27) and volunteer comparison control subjects (n = 27). MEASUREMENTS Subjective reports of sleep, mood symptoms and pain, polysomnographic assessment of sleep continuity, and subjective and objective assessment of rheumatoid arthritis-specific joint pain. RESULTS PSD induced differential increases in self-reported fatigue (P < 0.09), depression (P < 0.04), anxiety (P < 0.04), and pain (P < 0.01) in patients with rheumatoid arthritis compared with responses in control subjects, in whom differential increases of self-reported pain were independent of changes in mood symptoms, subjective sleep quality, and objective measures of sleep fragmentation. In the patients with rheumatoid arthritis, PSD also induced increases in disease-specific activity as indexed by self-reported pain severity (P < 0.01) and number of painful joints (P < 0.02) as well as clinician-rated joint counts (P < 0.03). CONCLUSION This study provides the first evidence of an exaggerated increase in symptoms of mood and pain in patients with rheumatoid arthritis after sleep loss, along with an activation of rheumatoid arthritis-related joint pain. Given the reciprocal relationship between sleep disturbances and pain, clinical management of pain in patients with rheumatoid arthritis should include an increased focus on the prevention and treatment of sleep disturbance in this clinical population.

Objectives Reverse cholesterol transport (RCT) is a major antiatherogenic function of high density lipoprotein (HDL). In the current work, the authors evaluated whether the RCT capacity of HDL from rheumatoid arthritis (RA) patients is impaired when compared to healthy controls. Methods HDL was isolated from 40 patients with RA and 40 age and sex matched healthy controls. Assays of cholesterol efflux, HDLs antioxidant function and paraoxanase-1 (PON-1) activity were performed as described previously. Plasma myeloperoxidase (MPO) activity was assessed by a commercially available assay. Results Mean cholesterol efflux capacity of HDL was not significantly different between RA patients (40.2%±11.1%) and controls (39.5%±8.9%); p=0.75. However, HDL from RA patients with high disease activity measured by a disease activity score using 28 joint count (DAS28>5.1), had significantly decreased ability to promote cholesterol efflux compared to HDL from patients with very low disease activity/clinical remission (DAS28<2.6). Significant correlations were noted between cholesterol efflux and the DAS28 (r=−0.39, p=0.01) and erythrocyte sedimentation rate, (r=−0.41, p=0.0009). Higher plasma MPO activity was associated with worse HDL function (r=0.41/p=0.009 (antioxidant capacity); r=0.35, p=0.03 (efflux)). HDLs ability to promote cholesterol efflux was modestly but significantly correlated with its antioxidant function (r=−0.34, p=0.03). Conclusions The cholesterol efflux capacity of HDL is impaired in RA patients with high disease activity and is correlated with systemic inflammation and HDLs antioxidant capacity. Attenuation of HDL function, independent of HDL cholesterol levels, may suggest a mechanism by which active RA contributes to increased cardiovascular (CV) risk.

OBJECTIVE Pulmonary arterial hypertension (PAH) affects up to 15% of patients with connective tissue diseases (CTDs). Previous recommendations developed as part of larger efforts in PAH did not include detailed recommendations for patients with CTD-associated PAH. Therefore, we sought to develop recommendations for screening and early detection of CTD-associated PAH. METHODS We performed a systematic review of the literature on the screening and diagnosis of PAH in CTD. Using the RAND/University of California, Los Angeles consensus methodology, we developed case scenarios followed by 2 stages of voting. First, international experts from a variety of specialties voted anonymously on the appropriateness of each case scenario. The experts then met face-to-face to discuss and resolve discrepant votes to arrive at consensus recommendations. RESULTS The key recommendation stated that all patients with systemic sclerosis (SSc) should be screened for PAH. In addition, patients with mixed connective tissue disease or other CTDs with scleroderma features (scleroderma spectrum disorders) should be screened for PAH. It was recommended that screening pulmonary function tests (PFTs) with single-breath diffusing capacity for carbon monoxide, transthoracic echocardiogram, and measurement of N-terminal pro-brain natriuretic peptide (NT-proBNP) be performed in all patients with SSc and scleroderma spectrum disorders. In patients with SSc and scleroderma spectrum disorders, transthoracic echocardiogram and PFTs should be performed annually. The full screening panel (transthoracic echocardiogram, PFTs, and measurement of NT-proBNP) should be performed as soon as any new signs or symptoms are present. CONCLUSION We provide consensus-based, evidence-driven recommendations for screening and early detection of CTD-associated PAH. It is our hope that these recommendations will lead to earlier detection of CTD-associated PAH and ultimately improve patient outcomes.

An increased frequency of atherosclerosis (ATH) in systemic lupus erythematosus (SLE) is well‐documented but not fully explained by the presence of traditional cardiac risk factors. Several nontraditional biomarkers, including proinflammatory high‐density lipoprotein (piHDL) and leptin, have been individually associated with subclinical ATH in SLE. The aim of this study was to examine whether these and other biomarkers can be combined into a risk profile, the Predictors of Risk for Elevated Flares, Damage Progression, and Increased Cardiovascular Disease in Patients with SLE (PREDICTS), that could be used to better predict future progression of ATH.

OBJECTIVE Acute gout is traditionally treated with NSAIDs, corticosteroids, and colchicine; however, subjects have multiple comorbidities that limit the use of some conventional therapies. We systematically reviewed the published data on the pharmacologic and non-pharmacologic agents used for the treatment of acute gouty arthritis. METHODS A systematic search was performed using PubMed and Cochrane database through May 2013. We included only randomized controlled trials (RCTs) that included NSAIDs, corticosteroids, colchicine, adrenocorticotropic hormone (ACTH), interleukin-1 (IL-1) inhibitors, topical ice, or herbal supplements. RESULTS Thirty articles were selected for systematic review. The results show that NSAIDs and COX-2 inhibitors are effective agents for the treatment of acute gout attacks. Systemic corticosteroids have similar efficacy to therapeutic doses of NSAIDs, with studies supporting oral and intramuscular use. ACTH is suggested to be efficacious in acute gout. Oral colchicine demonstrated to be effective, with low-dose colchicine demonstrating a comparable tolerability profile as placebo and a significantly lower side effect profile to high-dose colchicine. The IL-1β inhibitory antibody, canakinumab, was effective for the treatment of acute attacks in subjects refractory to and in those with contraindications to NSAIDs and/or colchicine. However, rilonacept was demonstrated to be not as effective, and there are no RCTs for the use of anakinra. CONCLUSION NSAIDs, COX-2 selective inhibitors, corticosteroids, colchicine, ACTH, and canakinumab have evidence to suggest efficacy in treatment of acute gout.
