The Causal Relationship between Angina Pectoris and Gout Based on Two Sample Mendelian Randomization.

Two-sample Mendelian randomization (MR) was conducted to assess the causal relationship between angina pectoris and gout. Material and Methods. Based on genome-wide association studies, single nucleotide polymorphisms (SNPs) that were closely associated with gout were selected from the UK Biobank-Neale Lab (ukb-a-107) as genetic instrumental variables. Considering that gout is characterized by elevated blood uric acid levels, SNPs related to blood uric acid levels were screened from BioBank Japan (bbj-a-57) as auxiliary gene instrumental variables. SNPs closely associated with angina pectoris onset were screened from the FINN dataset (finn-b-I9_ANGINA) as outcome variables. Two-sample MR was conducted, with inverse variance weighting (IVW) of the random effects model as the primary result, along with the weighted median method (WME) and the MR-Egger regression method. To further confirm the causal relationship between angina and gout incidence, a meta-analysis was conducted on the IVW results of the ukb-a-107 and bbj-a-57. The odds ratios and 95% confidence intervals of the IVW, WME, and MR-Egger results of ukb-a-107 were (OR = 33.72; 95% CI: 2.07∼550.38), (OR = 57.94; 95% CI: 2.75∼1219.82), and (OR = 96.38; 95% CI: 0.6∼15556.93), respectively. The P values of IVW and WME were 0.014 and 0.014 (both <0.05), respectively, indicating that the development of angina pectoris was significantly associated with the incidence of gout. The odds ratios and 95% confidence intervals of the IVW, WME, and MR-Egger about bbj-a-57 were (OR = 1.20; 95% CI: 1.07∼1.34), (OR = 1.19; 95% CI: 1.02∼1.38), and (OR = 1.30; 95% CI; 1.06∼1.60), respectively. The P values of IVW, WME and MR-Egger were 0.001, 0.027 and 0.017 (all <0.05), respectively, indicating a significant correlation between angina and blood uric acid levels. Scatter plots of ukb-a-107 and bbj-a-57 showed that the causal association estimates of the IVW, MR-Egger, and weighted median methods were similar and that the MR results were accurate. Funnel plots and the MR-Egger intercept of ukb-a-107 and bbj-a-57 showed the absence of horizontal pleiotropy. The leave-out sensitivity analysis results of ukb-a-107 and bbj-a-57 are stable. The meta-analysis of IVW results for ukb-a-107 and bbj-a-57 showed (OR = 1.20; 95% CI: 1.07-1.34, P=0.02), confirming that gout characterized by high blood uric acid levels significantly increases the risk of angina attacks. This MR study found a clear causal relationship between angina pectoris and gout, which increases the risk of angina pectoris.

Association between combined exposure to ambient air pollutants, genetic risk, and incident gout risk: A prospective cohort study in the UK Biobank

BackgroundLimited research has been conducted on the association between long-term exposure to air pollutants and the incidence of gout. ObjectivesThis study aims to assess the individual and combined effects of prolonged exposure to five air pollutants (NO2, NOx, PM10, PMcoarse and PM2.522NO2, nitrogen dioxide; NOx, nitrogen oxides; PM10, particulate matter with diameters ≤ 10 µm; PMcoarse, particulate matter with diameters between 2.5 and 10 µm;PM2.5, particulate matter with diameters ≤ 2.5 µm.) on the incidence of gout among 458,884 initially gout-free participants enrolled in the UK Biobank. MethodsEmploying a land use regression model, we utilized an estimation method to ascertain the annual concentrations of the five air pollutants. Subsequently, we devised a weighted air pollution score to facilitate a comprehensive evaluation of exposure. The Cox proportional hazards model was utilized to investigate the association between ambient air pollution and gout risk. Interaction and stratification analyses were conducted to evaluate age, sex, BMI, and genetic predisposition as potential effect modifiers in the air pollution-gout relationship. Furthermore, mediation analyses were conducted to explore the potential involvement of biomarkers in mediating the association between air pollution and gout. ResultsOver a median follow-up time of 12.0 years, 7,927 cases of gout were diagnosed. Significant associations were observed between the risk of gout and a per IQR increase in NO2 (HR33HR, hazard ratio.: 1.05, 95 % CI44CI, confidence interval.: 1.02–1.08, p = 0.003), NOx (HR: 1.04, 95 % CI: 1.01–1.06, p = 0.003), and PM2.5 (HR: 1.03, 95 % CI: 1.00–1.06, p = 0.030). Per IQR increase in the air pollution score was associated with an elevated risk of gout (p = 0.005). Stratified analysis revealed a significant correlation between the air pollution score and gout risk in participants ≥60 years (HR: 1.05, 95 % CI: 1.02–1.09, p = 0.005), but not in those <60 years (p = 0.793), indicating a significant interaction effect with age (p-interaction=0.009). Mediation analyses identified five serum biomarkers (SUA:15.87 %, VITD: 5.04 %, LDLD: 3.34 %, GGT: 1.90 %, AST: 1.56 %55UA, urate; HDL, high-density lipoprotein; VITD, vitamin D; LDLD, low density lipoprotein direct; GGT, gamma glutamyltransferase; AST, aspartate aminotransferase.) with potential mediation effects on this association. ConclusionsLong-term exposure to air pollutants, particularly among the elderly population, is associated with an increased risk of gout. The underlying mechanisms of these associations may involve the participation of five serum biomarkers.

Changes in Serum Urate Levels after Bariatric Surgery in Patients with Obesity: An Observational Study

BackgroundObesity is a risk factor for hyperuricemia and gout, while weight reduction can reduce urate levels. The aim of this study was to examine the effect of bariatric surgery on longitudinal serum urate levels.MethodsWe performed a retrospective observational study of 283 patients who had undergone bariatric surgery [237 (83.7%) gastric bypass, 34 (12.0%) sleeve gastrectomy and 12 (4.2%) gastric banding] and were followed up for 2 years. The results shown represent mean (standard deviation).ResultsBariatric surgery was associated with significant reduction in serum urate from baseline level of 0.343 (0.086) mmol/L to 0.296 (0.076) mmol/L (p < 0.001) at 12 months and 0.286 (0.073) mmol/L (p < 0.001) at 24 months, including in men and women, and in patients with or without diabetes. Patients with elevated urate levels at baseline, who comprised 27.2% of the total cohort, achieved reduction in levels by 4 months.ConclusionBariatric surgery leads to significant reduction in serum urate levels at 12 and 24 months. This could reduce incidence of gout and need for prophylactic medication(s).Graphical

The clinical benefits of sodium-glucose cotransporter type 2 inhibitors in people with gout.

Gout is the most common form of inflammatory arthritis worldwide and is characterized by painful recurrent flares of inflammatory arthritis that are associated with a transiently increased risk of adverse cardiovascular events. Furthermore, gout is associated with multiple cardiometabolic-renal comorbidities such as type 2 diabetes, chronic kidney disease and cardiovascular disease. These comorbidities, potentially combined with gout flare-related inflammation, contribute to persistent premature mortality in gout, independently of serum urate concentrations and traditional cardiovascular risk factors. Although better implementation of standard gout care could improve gout outcomes, deliberate efforts to address the cardiovascular risk in patients with gout are likely to berequired to reduce mortality. Sodium-glucose cotransporter type 2 (SGLT2) inhibitors are approved for multiple indications owing to their ability to lower the risk of all-cause and cardiovascular death, hospitalizations for heart failure and chronic kidney disease progression, making them an attractive treatment option for gout. These medications have also been shown to lower serum urate concentrations, the causal culprit in gout risk, and are associated with a reduced risk of incident and recurrent gout, potentially owing to their purported anti-inflammatory effects. Thus, SGLT2 inhibition could simultaneously address both the symptoms of gout and its comorbidities.

Pathophysiology and Treatment of Gout Arthritis; including Gout Arthritis of Hip Joint: A Literature Review.

Gout is triggered by the accumulation of uric acid in the body, leading to hyperuricemia. Genetic, metabolic, and environmental factors can influence this condition. Excessive uric acid buildup results in the formation of monosodium urate (MSU) crystals, which precipitate in specific areas of the body, including the joints, where they can cause symptoms of gout. While the acute and chronic symptoms of gout have been well-documented, diagnosis of gout affecting the hip joint poses significant challenges. The global incidence of gout, the most prevalent form of inflammatory arthritis, is on the rise. Evaluation of the clinical signs, laboratory results, and imaging results is generally required for diagnosis of gout in cases where MSU crystals have not been detected. Hyperuricemia is considered a primary cause of arthritis symptoms, and comprehensive guidelines for treatment are available. Therefore, the choice of medication is straightforward, and moderate effectiveness of treatment has been demonstrated. Gout is a chronic disease, requiring lifelong uric acid-lowering medications, thus application of a treatment strategy based on the target blood uric acid concentration is necessary. Consequently, cases of gout will likely be observed more frequently by hip surgeons in clinical scenarios in the future. The objective of this review is to provide an overview of the pathophysiology of gout and subsequently examine recent advances in diagnostic methods and therapeutic agents based on an understanding of its underlying mechanisms. In addition, literature on gout-related issues affecting the hip joint, providing a useful reference for hip surgeons is examined.

Trends in healthcare utilization by patients with gout: A cross-sectional study using Health Insurance Review and Assessment Service data.

This study aimed to analyze the distribution of gout patients and the utilization of healthcare services in South Korea to provide valuable recommendations to clinicians and policymakers. A cross-sectional study was conducted. Claims data from the Health Insurance Review and Assessment Service spanning 2010 to 2019 were utilized, and a sample of 69,680 patients was included in the study. The incidence of gout was observed to be high in male patients over the age of 40, with most patients receiving outpatient care for gout management. Nonsteroidal anti-inflammatory drugs and urate-lowering agents were the most frequently prescribed medications, with prescriptions for colchicine and febuxostat increasing among urate-lowering agents. Musculoskeletal disorders were found to be the most common comorbidities among gout patients. Although the total costs of gout management increased, there was no significant increase in cost per patient. This study provides insights into the current state of healthcare utilization for gout patients in South Korea and trends in the disease burden and use of medications. The findings have crucial implications for clinicians and policymakers involved in decision-making regarding the management and treatment of gout.

Unclosing Premature Mortality Gap Among Patients With Gout in the US General Population, Independent of Serum Urate and Atherosclerotic Cardiovascular Risk Factors.

Gout flares are followed by transient major cardiovascular (CV) risk, implicating the role of inflammation; the aim of this study was to determine whether premature mortality rates in patients with gout and CV risk are independent of serum urate (SU) and atherosclerotic CV disease (ASCVD) risk factors. Using serial US nationwide prospective cohorts, we evaluated the independent association of prevalent gout with all-cause and CV mortality, adjusting for SU, ASCVD risk factors, comorbidities, medications, and kidney function and compared mortality rates between the early (1988-1994 baseline) and late cohorts (2007-2016 baseline). We replicated late cohort findings among patients with gout in a nationwide UK cohort (2006-2010 baseline). Adjusted hazard ratios (HRs) for mortality rates in patients with prevalent gout were similar in early and late US cohorts (1.20 [1.03-1.40] and 1.19 [1.04-1.37], respectively); HRs with further adjustment for SU were 1.19 (1.02-1.38) and 1.19 (1.03-1.37), respectively. Adjusted HR among patients with gout from the UK late cohort was 1.61 (1.47-1.75); these associations were larger among women (P = 0.04) and prominent among Black individuals. Adjusted HR for CV mortality rates in the late US cohort was 1.39 (1.09-1.78); those for circulatory, CV, and coronary heart disease deaths among UK patients with incident gout were 1.48 (1.24-1.76), 1.49 (1.20-1.85), and 1.59 (1.26-1.99), respectively. Patients with gout experience a persistent mortality gap in all-cause and CV deaths, even adjusting for SU and ASCVD risk factors, supporting a role for gout-specific pathways (eg, flare inflammation). These findings suggest gaps in current care, particularly in women and possibly among Black patients.

Long-term exposure to ambient air pollution and incident gout: A prospective cohort study in the UK Biobank

Gout is a chronic disorder characterized by the accumulation of uric acid in the body, leading to recurrent episodes of joint inflammation and pain. There remains a lack of studies investigating the association between long-term exposure to ambient air pollution and the incidence of gout. We conducted this prospective cohort study involving participants aged 38–70 from the UK Biobank who were enrolled in 2006–2010 and followed until 2023. Baseline residential concentrations of fine particulate matter (PM2.5), inhalable particulate matter (PM10), nitrogen dioxide (NO2) and nitrogen oxides (NOx) were predicted using land-use regression models. Cox proportional hazards models were employed to examine the relationship between air pollution and incident gout events. A total of 443,587 individuals were included in the analyses and a total of 6589 incident gout cases were identified over a follow-up of 6,130,439 person-years. There were significant associations between higher levels of air pollution and an increased incidence risk of gout. Higher risk of incident gout was associated with each interquartile range increase in concentrations of PM2.5 (hazard ratio:1.05, 95% confidence intervals: 1.02–1.09), PM10 (1.04, 1.00–1.07), NO2 (1.08, 1.05–1.12) and NOx (1.04, 1.02–1.07). The magnitude of associations was larger at higher concentrations. The association was more prominent among older adults, smokers, and individuals with lower and moderate physical activity. This prospective cohort study provides novel and compelling evidence of increased risk of incident gout associated with long-term air pollution exposures.

Secular trend of gout incidence in the UK: an age-period-cohort analysis

ObjectivesThe incidence of gout in the UK appears to have declined since 2013; however, whether such a trend occurred across participants born in different years (ie, birth cohort) is unknown....

The Impact of Different Intensities of Physical Activity on Serum Urate and Gout: A Mendelian Randomization Study.

Physical activity is a potential protective factor against gout, but the role of exercise intensity in this context remains unclear. To overcome the limitations of observational studies in causal inference, this study employed a two-sample Mendelian randomization approach to explore the impact of different genetically proxied/predicted intensities of physical activity on serum urate concentration and the incidence of gout. Our data related to physical activity, serum urate, and gout were obtained from the UK Biobank, the Global Urate Genetics Consortium (GUGC), and the FinnGen dataset, respectively. Walking was included as representative of typical low-intensity physical activity in the analysis, and the other two types were moderate and vigorous physical activities. The estimation methods we used included the inverse-variance-weighted (IVW) method, MR-Egger regression, weighted-median method, simple-mode method, and weighted-mode method. Sensitivity analyses involved Rucker's framework, Cochran's Q test, funnel plots, MR-PRESSO outlier correction, and leave-one-out analysis. We found suggestive evidence from the inverse-variance-weighted method that moderate physical activity was a potential factor in reducing the incidence of gout (OR = 0.628, p = 0.034), and this association became more substantial in our subsequent sensitivity analysis (OR = 0.555, p = 0.006). However, we observed no distinctive effects of physical activity on serum urate concentration. In conclusion, our study supports some findings from observational studies and emphasizes the preventive role of moderate physical activity against gout. Given the limitations of the existing datasets, we call for future reexamination and expansion of our findings using new GWAS data.

Relieving urinary tract obstructions may increase the risk of gouty arthritis in patients with hyperuricemia and postrenal obstructions.

To evaluate the effect of relieving urinary tract obstructions (RUO) on the risk of gouty arthritis in patients with postrenal obstructions and hyperuricemia. We retrospectively analyzed the clinical data of 130 patients with urinary tract obstructions at Rongcheng People's Hospital from 2018 to 2021. Patients were divided into groups A (n = 62) and B (n = 68) according to the treatment method. Patients in group A underwent conservative treatments, such as drugs, extracorporeal shock wave lithotripsy (ESWL), and hemodialysis. Patients in Group B underwent catheterization, cystostomy, nephrostomy, or double J ureteral catheterization for rapid RUO. The ages of groups A and B were 58.40 ± 17.69 and 59.63 ± 16.12 years, respectively (P = .42). Before treatment, the serum uric acid values were 572.05 ± 106.93 and 567.79 ± 97.21 µmol/L, respectively (P = .94); serum creatinine values were 226.66 ± 269.67 and 280.15 ± 200.75 µmol/L, respectively (P = .88); and urine volumes were 913.23 ± 481.92 and 886.18 ± 552.72 mL/24 h, respectively (P = .08). No significant differences in the general data were identified between the two groups (P > .05). The effects of the two treatments on the incidence of gout in patients with hyperuricemia complicated by postrenal obstruction were compared based on changes in uric acid level, creatinine level, and urine volume within 1 week after treatment. Multivariate logistic regression analysis was used to analyze clinical factors that increased the incidence of gout after RUO. The gout incidence rates in group A before and after treatment were 8.1% (5/62) and 6.5% (4/62), respectively (P > .99). The gout incidence rates in group B before and after treatment were 4.4% (3/68) and 19.1% (10/68), respectively (P = .01). Group B had a statistically significant increase in the gout incidence rate after RUO (P < .05). Multivariate logistic regression analysis showed that having an age > 60 years, urine volume ≤400 mL/24 h, and creatinine level > 186 µmol/L before treatment were risk factors for gout in patients with hyperuricemia after RUO. Relieving urinary tract obstruction increases the risk of gouty arthritis in patients with hyperuricemia and acute postrenal obstruction. Age, urine volume, and creatinine levels before treatment are risk factors for gout in patients with hyperuricemia after RUO.

Lower plasma linoleic acids as a risk factor for gout: an integrated analysis of population-based cohort and genetic data.

Background: Gout is a nutrition-related, highly prevalent inflammatory arthritis with undesirable effects on the quality of life. The relationships between circulating fatty acids (FAs) and gout remain poorly understood. Method: We included 268 174 participants with plasma FAs measured using nuclear magnetic resonance at the baseline (2006-2010) from the UK Biobank, of which 15 194 participants had repeated measures of FAs between 2012 and 2013. Cox proportional hazards models were used to assess the association of the baseline and longitudinal changes in relative levels of plasma FAs (% total FAs) with incident gout. Mendelian randomization (MR) analyses were conducted to assess the potential causality of the examined association. Results: Over a median follow-up of 12.8 years, 5160 incident cases of gout occurred. Baseline polyunsaturated fatty acids (PUFAs), n-6 PUFAs, and linoleic acids (LAs) were inversely associated with incident gout (all P-trend values < 0.0001). Baseline monounsaturated fatty acids (MUFAs), n-3 PUFAs, and docosahexaenoic acids (DHAs) were positively associated with incident gout (all P-trend values < 0.0001). Longitudinal increments of n-6 PUFAs and LAs were associated with a lower risk of subsequent gout, whereas an increment of n-3 PUFAs was associated with a higher risk. In two-sample MR analyses, genetically determined higher levels of PUFAs, n-6 PUFAs, and LAs were associated with a decreased risk of gout (all P values < 0.05). Conclusions: Our findings consistently indicate a causal relationship of elevated levels of n-6 PUFAs, especially LAs, with a reduced risk of gout.

Awareness of gout disease among adult population in Jazan, Saudi Arabia

Background: Gout is the most prevalent type of inflammatory arthritis, significantly impacting individuals\&amp;apos; quality of life. In the majority of cases, the first metatarsophalangeal joint experiences severe pain, edema, redness, and heat. In recent years, the incidence of gout has considerably increased. This study aimed at assessing the awareness of gout disease among adult population in Jazan, Saudi Arabia. Method: This cross-sectional study was conducted among adults in Jazan, Saudi Arabia, from February to March 2023. Data were collected through an electronic questionnaire, including inquiries about socio-demographic characteristics and awareness of gout disease. SPSS version 27 was used for data analysis, and chi-square tests were employed to assess factors associated with gout awareness. Results: There were 896 participants, with the majority (53.6%) being females. Most participants (48.7%) had a normal body mass index. Only 4% of the participants had gout. We found that 27.1% of participants had poor, 43.9% had moderate, and 29.1% had excellent gout awareness. There was a significant correlation between participants\&amp;apos; awareness scores and their education level, presence of gout disease, family history of gout, and the source of information about gout. Conclusion: Gout stands out as the most common inflammatory arthritis, imposing a significant financial and health burden globally. In the Jazan region, the general population exhibited an inadequate level of awareness about gout. To enhance awareness of this crucial topic and minimize complications, campaigns, media, social media, and conferences are needed to educate Saudis about gout. These initiatives should focus on gout risk factors, symptoms, and genetic predisposition

Sacroiliitis in gout: Difficulties of diagnosis

Gout is the most common chronic autoinflammatory disease, the development of which is associated with persistent hyperuricemia caused by both environmental and genetic factors, which leads to the deposition of sodium monourate crystals in various tissues and organs of the human body. Gout is more common in men than in women of childbearing age, due to the uricosuric effect of estrogen, however, after menopause, the incidence of gout in women increases significantly. At the onset of the disease, the first metatarsophalangeal joint, ankle and knee joints are most often involved in the pathological process. However, there are isolated reports in the literature about a rare gout lesion of the axial skeleton, for example, the sacroiliac joint, in which the nature of the pain syndrome, magnetic resonance imaging, and X-ray picture can mimic spondyloarthritis. The article presents a rare case of damage to the axial skeleton in a 57-year-old patient with gout, manifested by acute inflammatory back pain and arthritis of the lower extremities.

Epidemiology of gout - Global burden of disease research from 1990 to 2019 and future trend predictions.

Understanding the global burden of gout in the past and future can provide important references for optimizing prevention and control strategies in healthcare systems. This study aimed to report variations in the global disease burden and risk factors of gout in 204 countries and territories from 1990 to 2019. We conducted a retrospective analysis of gout based on the latest Global Burden of Disease (GBD) 2019 database. We collected data on the prevalence, incidence, and disability-adjusted life years (DALYs) of gout from 1990 to 2019. The data were then stratified by age, sex, and economic development level. Decomposition analysis, frontier analysis, and prediction models were used to analyze the changes and influencing factors influencing each indicator. Globally, there were 53,871,846.4 [95% uncertainty interval (UI): 43,383,204.6-66,342,327.3] prevalent cases, 92,228,86.8 (95% UI: 7419,132.1-11,521,165) incident cases, and 1673,973.4 (95% UI: 1,068,061.1-2,393,469.2) cases of DALYs of gout in 2019, more than double those in 1990. Moreover, the pace of increase in the age-standardized prevalence rate (ASPR), age-standardized incidence rate (ASIR), and age-standardized DALY rate (ASDR) accelerated during 1990-2019, with estimated annual percentage changes (EAPC) of 0.94 [95% confidence interval (CI): 0.85-1.03], 0.77 (95% CI: 0.69-0.84), and 0.93 (95% CI: 0.84-1.02), respectively, especially among men. The disease burden of gout has increased in all the other 20 GBD regions in the past 30 years, except Western Sub-Saharan Africa. The highest risk of high body mass index (BMI) and kidney dysfunction was in high-income countries such as North America and East Asia. The global prevalence rate, incidence rate, and DALYs rate of gout in 2030 will reach 599.86, 102.96 per 100,000 population, and 20.26 per 100,000 population, respectively, roughly the same as in 2019. With the development of society, the disease burden of gout will become increasingly severe. It is very important to study the accurate epidemiological data on gout for clinical diagnosis and treatment and health policy.

The Evolving Landscape of Gout in the Female: A Narrative Review

Gout is at least three times more prevalent in males than in females. However, concurrent with rising total gout prevalence, complex factors, including comorbidities, diet, lifestyle, and aging, have promoted higher gout prevalence in females. This narrative review focuses on summarizing recent developments in the landscape of gout in females and the mechanisms involved. New knowledge on sex hormone effects on both urate-excreting and urate-reabsorbing transporters and higher hypertension and chronic kidney disease prevalence in females compared to males may help explain why gout incidence rises robustly after menopause in females, to approach that in males. Racial and ethnic factors, risk profiles based on heritable genetic polymorphisms of urate transporters, diet, body mass index, and lifestyle factors differ according to sex. In addition, sex differences in clinical phenotypes, outcomes of gout, and non-gout illnesses include more frequent comorbidities, more pain and disability during gout flares, different perceptions of disease burden, and more frequent severe cutaneous hypersensitivity reaction to allopurinol in females. Collectively, such findings support the potential clinical benefits of tailoring gout and hyperuricemia treatment according to sex.

Hypertension is called the silent killer because many people do not realize that they have hypertension, the incidence of gout continues to increase with age. This activity aims to provide education and measurement (screening) for blood pressure and uric acid for all educational and educational staff as well as the community around the campus of the Indonesian Christian University, Maluku, totaling 122 people. The method used is point of care testing (POCT) using a blood pressure measurement device (tensimeter) and uric acid through blood tests. The results obtained were that the majority of respondents had a blood pressure category of pre hypertension and above, namely pre hypertension at 33.6%, grade 1 hypertension at 17.2% and grade 2 hypertension at 6.6%, while for uric acid levels the majority of respondents had the category the maximum is 6 – 7.9 mg/dl and above with details of the percentage of uric acid levels of 6 – 7.9 mg/dl amounting to 35.2%, 8 – 9.9 mg/dl amounting to 15.2% and ≥ 10 mg/dl dl of 9.8%. In conclusion, prevention efforts need to be carried out through implementing a healthy diet, good physical activity and controlling genetic factors

Effectiveness and safety of different doses of febuxostat compared with allopurinol in the treatment of hyperuricemia: a meta-analysis of randomized controlled trials

BackgroundThe prevalence of hyperuricemia has increased steadily with the continuous improvement of living standards. Some studies have reported the clinical effectiveness and safety of different doses of febuxostat in comparison with allopurinol in hyperuricemia treatment, but the sample sizes of the studies have been small, and the results have been inconsistent. We designed this meta-analysis to evaluate the effectiveness and safety of different doses of febuxostat compared with allopurinol in the treatment of hyperuricemia.MethodsThe Cochrane Library, Embase, PubMed, Web of Science and ClinicalTrials.gov databases were searched to identify randomized controlled trials (RCTs) comparing the use of febuxostat and allopurinol for the treatment of hyperuricemia. The effectiveness and safety of different doses of febuxostat and allopurinol in treating hyperuricemia were assessed using meta-analysis.ResultsA total of 11 randomized controlled trials were included in the meta-analysis. The results of the meta-analysis showed that the percentage of patients achieving serum uric acid levels of 6.0 mg/dL or less was higher among patients taking febuxostat (80 mg/d) than among patients taking allopurinol (200–300 mg/d) [RR = 1.79, 95% CI (1.55, 2.08), P < 0.00001]. However, there was no statistically significant difference in the percentage of patients achieving serum uric acid levels of 6.0 mg/dL or less between febuxostat (40 mg/d) and allopurinol (200–300 mg/d) [RR = 1.10, 95% CI (0.93, 1.31), P = 0.25]. There was also no statistically significant difference in the incidence of gout between the febuxostat (40 mg/d) and allopurinol (200–300 mg/d) [RR = 0.97, 95% CI (0.64, 1.49), P = 0.91] or between the febuxostat (80 mg/d) and allopurinol (200–300 mg/d) [RR = 1.13, 95% CI (0.81, 1.58), P = 0.48].No significant difference in the incidence of major adverse reactions as observed between the febuxostat (40 mg/d) and allopurinol (200–300 mg/d) [RR = 1.16; 95% CI (0.43, 3.16), P = 0.77] or between the febuxostat (80 mg/d) and allopurinol (200–300 mg/d) [RR = 1.06; 95% CI (0.79, 1.42), P = 0.70]. The incidence of adverse cardiovascular events did not differ significantly between the febuxostat (40 mg/d) and allopurinol (200–300 mg/d) [RR = 1.30; 95% CI (0.57, 2.95), P = 0.53] or between the febuxostat (80 mg/d) and allopurinol (200–300 mg/d) [RR = 1.79; 95% CI (0.74, 4.32), P = 0.20].ConclusionsFebuxostat (80 mg/d) was associated with a higher percentage of patients achieving serum uric acid levels of 6.0 mg/dL or less than allopurinol (200–300 mg/d), however, febuxostat (80 mg/d) did not exhibit better efficacy in reducing the incidence of gout. More attention should be devoted to the adverse reactions caused by an increase in febuxostat doses.

Cohort study investigating gout flares and management in UK general practice

BackgroundGout is the most common inflammatory arthritis and is almost exclusively managed in primary care, however the course and severity of the condition is variable and poorly characterised. This research aims improve understanding about the frequency of, and factors associated with, gout flares in the UK and characterise the factors associated with the initiation of ULT.MethodsUsing the Clinical Practice Research Database, patients with a coded incident gout diagnosis without a prior prescription for urate-lowering therapy (ULT) were identified. Gout flares post diagnosis and ULT initiation were identified through prescribing and coded data. Patient characteristics, co-morbidities and co-prescribing were co-variants. Factors associated with gout flares and ULT initiation were analysed using cox-proportional hazard model and logistic regression.ResultsFifty-one thousand seven hundred eighty-four patients were identified: 18,605 (35.9%, 95%CI 35.5–36.3%) had experienced ≥ 1 recurrent flare, 17.4% (95%CI 17.1–17.8%) within 12 months of diagnosis. Male sex, black ethnicity, higher BMI, heart failure, CKD, CVD and diuretic use were associated with flares, with the highest HR seen with high serum urate levels (≥ 540 µmol/L HR 4.63, 95%CI 4.03–5.31). ULT initiation was associated with similar variables, although higher alcohol intake and older age were associated with lower odds of ULT initiation but were not associated with flares. ULT was initiated in 27.7% (95%CI 27.3–28.0%): 5.7% (95%CI 5.5–5.9%) within 12 months of diagnosis. ULT initiation rates were higher in patients with recurrent flares.ConclusionApproximately one in six people with incident gout had a second flare within 12 months. Factors associated with flare recurrence and ULT initiation were similar, but ULT initiation occurred later after diagnosis than previously thought.

There are still many elderly people who do not know about healthy eating patterns, whether it is the type of food, and the amount of food so that many people get sick because of wrong eating patterns. One of them is gout. Correlation research design with cross sectional approach and sampling method with probability sample technique. The population is 60 elderly. With a sample of some of the elderly as many as 52 elderly. The instrument in this study used a questionnaire. Analysis using Spearman test. The results of this study were obtained who have eating patterns in the category of sometimes as many as 29 respondents (55.8%). And those who have an eating pattern in the rare category are 23 respondents (44.2%). Meanwhile, in the incidence of gout, almost all respondents had high uric acid incidence as many as 40 respondents (76.9%). And normal as many as 11 (21.2%). And low as much as 1 (1.9%). The results of the statistical test of the spearman rho test with a correlation coefficient of p = 0.004 (p = 0.004 &lt; = 0.005). It can be concluded that the variable diet has a significant relationship with the incidence of gout and there is a relationship between diet and the incidence of gout in the elderly. Elderly with an unhealthy diet have high uric acid levels (Lk: &gt; 7.0 Pr : &gt; 6.0), while the elderly with a healthy diet have normal uric acid levels (Lk: 3.5-7.0 Pr: 2.6-6.0). Most elderly have unhealthy eating patterns, and it is found that most elderly have high uric acid levels.
