Acute gout attacks and the long-term complications of gout are associated with the deposition of monosodium urate (MSU) monohydrate crystals in the joints and soft tissues, causing acute and chronic inflammation. The aim of long-term treatment is to reduce the serum urate (sUA) level to 6 mg/dl (< or =360 micromol/l), below the saturation point of MSU, so that new crystals cannot form and existing crystals are dissolved. Serial joint aspiration studies confirmed the disappearance of crystals with effective urate-lowering therapy. There is good evidence that achieving sUA <6 mg/dl (360 micromol/l) results in freedom from acute gout attacks, and shrinkage and eventual disappearance of tophi. Gout patients must be informed about their diagnosis and educated about gout management including the importance of compliance with long-term treatment. Patients starting urate-lowering therapy need to understand the importance of prophylactic therapy with colchicine or NSAIDs to reduce the risk of 'mobilization flares' in the first few months. In the long term, reduction in the sUA below the target level will result in gout being effectively cured.

    • "[28] Lifestyle modification is also recommended for gout management—in particular, weight control, regular exercise and a reduction in the consumption of red meat, alcohol and high fructose corn syrup, which can elevate sUA levels via metabolism .[26] [29] [30] While beneficial for general health, these lifestyle measures have relatively modest effects on sUA burden and gout symptoms, and few patients reach management targets by these measures alone.[3] [24] Despite the availability of management guidelines, there is continuing evidence that gout is not being managed effectively in a substantial proportion of patients.

    ABSTRACT: Objectives: Gout is a chronic, extremely painful disease that is potentially curable when treated effectively. Unfortunately approximately one-half of patients with gout are inadequately controlled. Methods: We surveyed 315 primary care physicians in the United States and Europe to investigate current practice in the real world, as distinct from recommendations in guidelines. Results: Our survey on 1657 patients found that regular testing of serum uric acid, in conformity with the guidelines, was conducted by approximately 50% of physicians. Advice to patients on diet and lifestyle was less well implemented, and identification of overweight/obese patients was inconsistent. Conclusion: Improvements in practice by physicians would include comprehensive assessment of the patient, adoption of regular monitoring during treatment, and the provision of patient education on adherence and lifestyle.

    • "The prevalence of gout has increased over the past few decades to 3.9% of US adults (8.3 million individuals) [1], which is further complicated by a high level of cardiovascular, metabolic, and renal comorbidities [2]. The pathogenesis of gout is well understood; high levels of circulating serum uric acid (SUA) lead to the acute and chronic manifestations of gout via the deposition of monosodium urate crystals in the joints and the soft tissues [3]. Reducing SUA levels effectively " cures " the disease [4], and guidelines including the American College of Rheumatology [5] and the European League Against Rheumatism [6] recommend lowering SUA levels to target levels (o 6 mg/dL or o 5 mg/dL), as well as reducing recurrent attacks, destructive arthropathy, renal disease, and comorbidity.

    ABSTRACT: Gout is a painful and disabling joint disease that constitutes the most common inflammatory arthritis in the US. To clarify the economic impact of gout, we systematically reviewed the literature on the direct and indirect costs associated with this disease. We conducted a literature search of MEDLINE, EMBASE, International Pharmaceutical Abstracts, NHS Economic Evaluation, and CINAHL databases to identify studies of gout and economics. We systematically reviewed published studies that met our inclusion criteria and extracted and summarized all relevant economic parameters. Reported costs were inflation-adjusted to 2013 US dollars (USD). A total of 15 studies met all eligibility criteria. Three controlled studies reported all-cause total direct costs based on specific populations (i.e., $4733, $16,925, and $18,362 per capita among employed, elderly, and treatment-refractory gout populations, respectively, and $2562, $10,590, and $7188 among corresponding non-gout patients). Two additional studies, although uncontrolled, allowed for estimation of total all-cause direct costs in unselected gout populations ($11,080 and $13,170). Gout-related costs ranged from $172 to $6179, depending on population characteristics. Six studies reported positive associations of direct costs with SUA level, gout attack frequency, or presence of tophi. Four studies reported on indirect costs, which were estimated to be as high as $4341 USD. The available data suggest that gout patients incur substantially greater direct and indirect costs as compared with gout-free individuals among elderly and treatment-refractory gouty patients, whereas the costs are considerably less among younger, employed gouty patients. Further, direct costs increased with worsening disease characteristics. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Introduction. Febuxostat, a novel xanthine oxidase inhibitor for the treatment of symptomatic hyperuricemia, showed superiority over allopurinol in the reduction of serum uric acid levels in pivotal studies. Whether this holds true the FORTE (febuxostat in the oral urate lowering treatment: effectiveness and safety) study was conducted to evaluate treatment with febuxostat under daily practice conditions. Materials/Methods. The multicentre, open-label, and prospective observational study was conducted in 1,690 German medical practices from 9/2010 to 5/2011. Safety and efficacy data were assessed at baseline and week 4. Results. Data from 5,592 gout patients (72.6% male, mean age 63.7 years) were collected. Under urate lowering treatment with febuxostat mean serum uric acid levels decreased significantly from 8.9 ± 1.9 mg/dL (534.0 ± 114.6 μmol/L) at baseline to 6.2 ± 2.5 mg/dL (372.0 ± 150.0 μmol/L) at week 4. 67% which reached the mean uric acid target (6.1 ± 1.0 mg/dL [366.0 ± 59.4 μmol/L]). Only 43.1% of patients received concomitant flare prophylaxis. A total of 178 adverse events (mostly gout flares) were reported in 152 patients (2.6%). Conclusion. Febuxostat lowers serum uric acid levels effectively in routine clinical practice. Overall, treatment with febuxostat in both available dosages (80 mg/120 mg) was safe and well tolerated.
