BACKGROUND
Hyperuricemia is reported to be related to rapid progression of renal function in patients with chronic kidney disease (CKD). Allopurinol, a uric acid lowering agent, protects renal progression. However, it is not widely used in patients with CKD because of its serious adverse event. Febuxostat can be alternatively used for patients who are intolerable to allopurinol. We aimed to determine renoprotective effect and urate-lowering effect between the two drugs.
METHODS
We performed a systematic review and meta-analysis of randomized controlled trials to assess the effects of febuxostat compared to allopurinol in patients with hyperuricemia. MEDLINE, Embase, and Cochrane Library databases were searched to identify research publications.
RESULTS
Four relevant publications were selected from among 3,815 studies. No significant differences were found in the changes in serum creatinine from baseline between the febuxostat and allopurinol groups. Changes in estimated glomerular filtration rate (eGFR) were observed between the two groups at 1 month (mean difference 1.65 mL/min/1.73 m, 95% confidence interval [CI] 0.38, 2.91 mL/min/1.73 m; heterogeneity χ = 1.25, I = 0%, = 0.01); however, the changes in eGFR were not significantly different at 3 months. A significant difference did exist in the changes in albuminuria levels from baseline between the febuxostat and allopurinol groups (mean difference -80.47 mg/gCr, 95% CI -149.29, -11.64 mg/gCr; heterogeneity χ = 0.81, I = 0%, = 0.02). A significant difference was also observed in the changes in serum uric acid from baseline between the febuxostat and allopurinol groups (mean difference -0.92 mg/dL, 95% CI -1.29, -0.56 mg/dL; heterogeneity χ = 6.24, I = 52%, < 0.001).
CONCLUSION
Febuxostat might be more renoprotective than allopurinol.

Review
Protective effect of allopurinol in preventing contrast-induced nephropathy among patients undergoing percutaneous coronary intervention: a systematic review and meta-analysis.
INTRODUCTION
Contrast-induced nephropathy (CIN) is the third most common cause of iatrogenic acute renal failure and is triggered by administration of radiopaque contrast media. Periprocedural hydration is imperative in prevention of CIN, and uric acid has been recognized to have an integral role in development of renal disease. The aim of our study is to understand the efficacy of allopurinol in preventing CIN among patients undergoing percutaneous coronary intervention.
MATERIAL AND METHODS
A literature search was performed on PubMed (Medline), Science Direct and Cochrane Library using a combination of Mesh terms. We limited our search to randomized controlled trials (RCTs) and articles published in the English language. The PRISMA protocol was utilized to conduct this meta-analysis.
RESULTS
Six studies were included in the final analysis. All included studies were clinical trials conducted between 2013 and 2019. A total of 853 patients were included. There was a significant reduction in the risk of CIN among patients who were pretreated with adequate hydration plus allopurinol (100 to 600 mg) compared to hydration only before undergoing percutaneous coronary angiography (RR = 0.39, 95% CI: 0.21-0.73). A sensitivity analysis of studies using 300 mg of allopurinol only reported a significant reduction in CI-AKI compared to hydration alone (RR = 0.26, 95% CI: 0.11-0.57).
CONCLUSIONS
Our study demonstrates that Allopurinol is effective in preventing contrast-induced nephropathy in patients undergoing percutaneous coronary intervention. Larger clinical trials are warranted to better understand this effect.

Meta-Analysis
Serum uric acid levels have been shown to be associated with increased risk of diabetes. However, it remains unclear whether uric acid-lowering therapy (ULT) is associated with improved glycemic status. This study aimed to summarize evidence from randomized controlled trials (RCTs) to investigate whether ULT reduces fasting blood glucose (FBG) and glycated hemoglobin A1c (HbA1c) levels. PubMed, Embase, and the Cochrane Library were searched from inception until April 10, 2019. Moreover, in order to maximize the search for articles on the same topic, the reference lists of included studies, relevant review articles and systematic reviews were reviewed. Parallel RCTs investigating the effect of ULT on FBG or HbA1c levels were considered for inclusion. An English language restriction was applied. Data were screened and extracted independently by two researchers. Meta-analyses were performed using random-effects models to calculate the weighted mean differences (WMDs) and 95% confidence intervals (CIs). Four trials with 314 patients reported the effect of ULT with allopurinol on FBG and 2 trials with 141 patients reported the effect of ULT with allopurinol on HbA1c. Treatment with allopurinol resulted in a significant decrease in FBG (WMD: -0.61 mmol/L, 95% CI: -0.93 to -0.28), but only a trend of reduction in HbA1c (WMD: -0.47%, 95% CI: -1.16 to 0.22). Notably, the subgroup analyses showed that treatment with allopurinol was associated with reduced FBG levels in patients without diabetes (WMD: -0.60 mmol/L, 95% CI: -0.99 to -0.20), but not in patients with diabetes. In addition, the dose of allopurinol treatment ≥200 mg daily resulted in a reduction of FBG levels (WMD: -0.59 mmol/L, 95% CI: -0.95 to -0.23), whereas low-dose allopurinol (<200 mg daily) had no effect on FBG levels. The findings suggest that ULT with allopurinol may be effective at reducing glycemia, but such an improvement does not appear to be observed in patients with diabetes. The findings require confirmation in additional trials with larger sample sizes.

Review
BACKGROUND
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disorder in which the two main clinical features are pelvic pain and lower urinary tract symptoms. There are currently many approaches for its management, using both pharmacological and non-pharmacological interventions. The National Institute of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) score is a validated measure commonly used to measure CP/CPPS symptoms. We considered a 25% decrease of NIH-CPSI baseline score or a six-point reduction as MCID.
OBJECTIVES
To assess the effects of pharmacological therapies for chronic prostatitis/chronic pelvic pain syndrome.
SEARCH METHODS
We performed a comprehensive search using CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, trial registries, grey literature and conference proceedings, with no restrictions on the language of publication or publication status. The date of the latest search of all databases was July 2019.
SELECTION CRITERIA
We included randomised controlled trials. Inclusion criteria were men with a diagnosis of CP/CPPS. We included all available pharmacological interventions compared to placebo or in head-to-head comparisons.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed study eligibility, extracted data, and assessed the risks of bias of included studies. We assessed the quality of the evidence (QoE) using the GRADE approach.
MAIN RESULTS
We included 99 unique studies in 9119 men with CP/CPPS, with assessments of 16 types of pharmacological interventions. Unless stated otherwise, our comparisons were based on short-term follow-up (less than 12 months). Most studies did not specify their funding sources; 21 studies reported funding from pharmaceutical companies.1. Alpha blockers: (24 studies, 2061 participants). We are uncertain about the effects of these drugs on prostatitis symptoms when compared to placebo at short-term follow-up (mean difference (MD) in total NIH-CPSI score -5.01, 95% confidence interval (CI) -7.41 to -2.61; 18 studies, 1524 participants, very low QoE) and at long-term follow-up (MD -5.60, 95% CI -10.89 to -0.32; 4 studies, 235 participants, very low QoE). Alpha blockers may be associated with an increased incidence of adverse events, such as dizziness and postural hypotension (risk ratio (RR) 1.60, 95% CI 1.09 to 2.34; 19 studies, 1588 participants; low QoE). Alpha blockers probably result in little to no difference in sexual dysfunction, quality of life and anxiety and depression (moderate to low QoE).2. 5-alpha reductase inhibitors (5-ARI): (2 studies, 177 participants). Finasteride probably reduces prostatitis symptoms compared to placebo (NIH-CPSI score MD -4.60, 95% CI -5.43 to -3.77; 1 study, 64 participants; moderate QoE) and may not be associated with an increased incidence of adverse events (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.3. Antibiotics: (6 studies, 693 participants). Antibiotics (quinolones) may reduce prostatitis symptoms compared to placebo (NIH-CPSI score MD -2.43, 95% CI -4.72 to -0.15; 5 studies, 372 participants; low QoE) and are probably not associated with an increased incidence in adverse events (moderate QoE). Antibiotics probably result in little to no difference in sexual dysfunction and quality of life (moderate QoE). There was no information on anxiety or depression.4. Anti-inflammatories: (7 studies, 585 participants). Anti-inflammatories may reduce prostatitis symptoms compared to placebo (NIH-CPSI scores MD -2.50, 95% CI -3.74 to -1.26; 7 studies, 585 participants; low QoE) and may not be associated with an increased incidence in adverse events (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.5. Phytotherapy: (7 studies, 551 participants). Phytotherapy may reduce prostatitis symptoms compared to placebo (NIH-CPSI scores MD -5.02, 95% CI -6.81 to -3.23; 5 studies, 320 participants; low QoE) and may not be associated with an increased incidence in adverse events (low QoE). Phytotherapy may not improve sexual dysfunction (low QoE). There was no information on quality of life or anxiety and depression.6. Botulinum toxin A (BTA): Intraprostatic BTA injection (1 study, 60 participants) may cause a large reduction in prostatitis symptom (NIH-CPSI scores MD -25.80, 95% CI -30.15 to -21.45), whereas pelvic floor muscle BTA injection (1 study, 29 participants) may not reduce prostatitis symptoms (low QoE). Both comparisons used a placebo injection. These interventions may not be associated with an increased incidence in adverse events (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.7. Allopurinol: (2 studies, 110 participants). Allopurinol may result in little to no difference in prostatitis symptoms and adverse events when compared to placebo (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.8. Traditional Chinese medicine (TCM): (7 studies, 835 participants); TCM may reduce prostatitis symptoms (NIH-CPSI score, MD -3.13, 95% CI -4.99 to -1.28; low QoE) and may not be associated with an increased incidence in adverse events (low QoE). TCM probably does not improve sexual dysfunction (moderate QoE) and may not improve symptoms of anxiety and depression (low QoE). There was no information on quality of life.The most frequent reasons for downgrading the QoE were study limitations, inconsistency and imprecision. We found few trials with active comparators.
AUTHORS' CONCLUSIONS
We found low- to very low-quality evidence that alpha blockers, antibiotics, 5-ARI, anti-inflammatories, phytotherapy, intraprostatic BTA injection, and traditional Chinese medicine may cause a reduction in prostatitis symptoms without an increased incidence of adverse events in the short term, except for alpha blockers which may be associated with an increase in mild adverse events. We found few trials with active comparators and little evidence of the effects of these drugs on sexual dysfunction, quality of life or anxiety and depression. Future clinical trials should include a full report of their methods, including adequate masking, consistent assessment of all patient-important outcomes, including potential treatment-related adverse events, and appropriate sample sizes.

Accumulating evidence suggests that hyperuricemia is a pathological factor in the development and progression of chronic kidney disease. However, the potential benefit afforded by the control of uric acid (UA) is controversial. Individual studies show discrepant results, and most existing meta-analysis, especially those including the larger number of studies, lack a placebo or control group as they aim to compare efficacy between drugs. On these grounds, we performed a me-ta-analysis restricted to studies including the action of any anti-gout therapies referenced to a control or placebo arm. This approach allows for a clearer association between UA reduction and renal effect. Of the twenty-nine papers included, most used allopurinol and febuxostat and, therefore, solid conclusions could only be obtained for these drugs. Both were very effective in reducing UA, but only allopurinol was able to significantly improve glomerular filtration rate (GFR), although not in a dose-dependent manner. These results raised doubts as to whether it is the hypouricemic effect of anti-gout drugs, or a pleiotropic effect, what provides protection of kidney function. Accordingly, in a correlation study that we next performed between UA reduction and GFR improvement, no association was found, which suggests that additional mechanisms may be involved. Of note, most trials show large inter-individual response variability, probably because they included patients with heterogeneous phenotypes and pathological characteristics, including different stages of CKD and comorbidities. This highlights the need to sub classify the effect of UA-lowering therapies according to the pathological scenario, in order to identify those CKD patients that may benefit most from them.

OBJECTIVES
Hospital admissions for gout flares have increased dramatically in recent years, despite widely available, effective medications for the treatment and prevention of flares. We conducted a systematic review to evaluate the effectiveness and implementation of interventions in patients hospitalized for gout flares.
METHODS
A search was conducted in MEDLINE, Embase and the Cochrane library, from database inception to 8 April 2021, using the terms 'gout' and 'hospital' and their synonyms. Studies were included if they evaluated the effectiveness and/or implementation of interventions during hospital admissions or emergency department attendances for gout flares. Risk of bias assessments were performed for included studies.
RESULTS
Nineteen articles were included. Most studies were small, retrospective analyses performed in single centres, with concerns for bias. Eleven studies (including five randomized controlled trials) reported improved patient outcomes following pharmacological interventions with known efficacy in gout, including allopurinol, prednisolone, NSAIDs and anakinra. Eight studies reported improved outcomes associated with non-pharmacological interventions: inpatient rheumatology consultation and a hospital gout management protocol. No studies to date have prospectively evaluated strategies designed to prevent re-admissions of patients hospitalized for gout flares.
CONCLUSION
There is an urgent need for high-quality, prospective studies of strategies for improving uptake of urate-lowering therapies in hospitalized patients, incorporating prophylaxis against flares and treat-to-target optimization of serum urate levels. Such studies are essential if the epidemic of hospital admissions from this treatable condition is to be countered.

Efficacy and safety of febuxostat for treating hyperuricemia in patients with chronic kidney disease and in renal transplant recipients: A systematic review and meta-analysis.
Febuxostat is potent and well-tolerated in the management of chronic gout. However, its clinical efficacy and safety in the treatment of hyperuricemia in patients with chronic kidney disease (CKD) and in renal transplant recipients have remained to be fully determined. The MEDLINE, EMBASE and Cochrane Library databases were searched for relevant articles. Data were extracted and pooled results were estimated from the standard mean difference (SMD) with 95% confidence intervals (95% CIs). The quality of the studies included was assessed, and their publication bias was examined. Four prospective randomized controlled trials and two retrospective observational studies were included in the systematic review and meta-analysis. Febuxostat administration significantly reduced the serum uric acid concentration in patients with CKD and in renal transplant recipients when compared with allopurinol or placebo in the short-term (1 month: SMD, -2.24; 95% CI, -3.59 to -0.89; P-value of SMD=0.001; I, 92.4%; 3 months: SMD, -1.20; 95% CI, -2.04 to -0.36; P-value of SMD=0.005; I, 88.9%; 6 months: SMD, -1.49; 95% CI, -2.68 to -0.30; P-value of SMD=0.014; I, 92.9%). Furthermore, the increase in the estimated glomerular filtration rate in the febuxostat group was significantly higher than that in the control group (SMD, 0.30; 95% CI, 0.031 to 0.58; P-value of SMD=0.029; I, 0.0%). No significant difference in the changes in serum creatinine (Scr), low-density lipoprotein (LDL) and high-density lipoprotein (HDL) was identified between the two groups (Scr: SMD, -0.17; 95% CI, -0.97 to 0.63; P-value of SMD=0.67; I, 79.2%; LDL: SMD, -0.21; 95% CI, -0.49 to 0.07; P-value of SMD=0.13; I, 34.1%; HDL: SMD, -0.05; 95% CI, -0.70 to 0.61; P-value of SMD=0.89; I, 69.2%). In conclusion, febuxostat is a potent and well-tolerated agent for the short-term management of hyperuricemia in patients with CKD and in renal transplant recipients. However, these data should be interpreted with caution due to the varied design of the studies included in the present meta-analysis.

Mayo Clinic Proceedings. Innovations,... Aug 2020To investigate the association between using febuxostat and cardiovascular events.
OBJECTIVE
To investigate the association between using febuxostat and cardiovascular events.
METHODS
Systematic search of randomized controlled trials was performed using PubMed/MEDLINE, Cochrane review, and EMBASE databases through April 17, 2019. Meta-analysis was performed using random effect model and estimates were reported as risk difference (RD) with 95% CIs. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. The main outcomes of interest were cardiovascular mortality and all-cause mortality.
RESULTS
A total of 15 randomized controlled trials (16,070 participants) were included. The mean ± SD age was 58.1±11.7 years. At the median follow-up of 6.4 months, use of febuxostat was not associated with statistically significant risk of cardiovascular mortality (RD, 0.12%; 95% CI, -0.25% to 0.49%; =48%; low certainty evidence), all-cause mortality (RD, 0.20%; 95% CI, -0.28% to 0.68%; =60%; very low certainty evidence), major adverse cardiovascular events (RD, 0.40%; 95% CI, -0.34% to 1.13%; =26%; low certainty evidence), myocardial infarction (RD, -0.06%; 95% CI, -0.29% to 0.17%; =0%; moderate certainty evidence), stroke (RD, 0.10%; 95% CI, -0.15% to 0.35%; =0%; moderate certainty evidence), or new-onset hypertension (RD, 1.58%; 95% CI, -0.63% to 3.78%; =58%; very low certainty evidence). These findings were consistent in patients with existing cardiovascular disease.
CONCLUSION
This meta-analysis suggested that use of febuxostat was not associated with higher risk of mortality or adverse cardiovascular outcomes in patients with gout and hyperuricemia. The results were limited by low to moderate certainty of evidence.

Meta-Analysis
BACKGROUND
Hyperuricemia and gout have become public health concerns; many important guidelines have recommended xanthine oxidase inhibitors (XOIs) as the first-line urate-lowering therapies (ULTs) to treat chronic gout with hyperuricemia. However, whether treating hyperuricemia and gout with ULTs modifies cardiovascular risks remains controversial. The aim of this study was to assess the incident risk of cardiovascular (CV) events (CVE) in hyperuricemia population, assess the cardiovascular benefit-risk of ULTs in hyperuricemia patients with or without gout in diverse cardiovascular risk sub-groups, and specify the safety of different ULTs.
METHODS
We searched PubMed, Embase, the Cochrane Library, Wanfang, Chongqing VIP (CQVIP, en.cqvip.com), and China National Knowledge Infrastructure Database for prospective cohort studies and randomized controlled trials (RCTs) in English and Chinese. Potential medications included XOIs, and uricosurics. RCTs were divided into sub-groups analysis based on blinding status and patients' history of CV diseases. Risk ratios (RRs) were calculated and were reported with corresponding 95% confidence intervals (CIs) by fixed-effects or random-effects model.
RESULTS
Seven prospective cohort studies and 17 RCT studies were included. The risks of both major adverse cardiovascular events (MACE) (RR = 1.72, 95% CI 1.28-2.33) and CVE (RR = 1.35, 95% CI 1.12-1.62) were higher in the hyperuricemia population than non-hyperuricemia one. In seven RCT studies where XOIs were compared with no-treatment or placebo, the results of five low CV risk studies showed that XOIs lowered the risks of both MACE (RR = 0.35, 95% CI 0.20-0.62) and CVE (RR = 0.61, 95% CI 0.44-0.85); whereas two high CV risk studies showed that XOIs lowered the risk of CVE (RR = 0.69, 95% CI 0.54-0.88) rather than MACE (RR = 0.62, 95% CI 0.29-1.35). In nine RCT studies where the cardiovascular safety between febuxostat and allopurinol were compared, no statistical difference was found in the risk of MACE or CVE.
CONCLUSIONS
The hyperuricemia population does have a higher incidence of CVE, and the results suggested that XOIs might reduce the incidence of MACE and total CVE. In addition, from the perspective of cardiovascular safety, febuxostat equaled allopurinol in our meta-analysis.

Annals of Internal Medicine Jan 2017Gout is a common type of inflammatory arthritis in patients seen by primary care physicians. (Review)
Review
BACKGROUND
Gout is a common type of inflammatory arthritis in patients seen by primary care physicians.
PURPOSE
To review evidence about treatment of acute gout attacks, management of hyperuricemia to prevent attacks, and discontinuation of medications for chronic gout in adults.
DATA SOURCES
Multiple electronic databases from January 2010 to March 2016, reference mining, and pharmaceutical manufacturers.
STUDY SELECTION
Studies of drugs approved by the U.S. Food and Drug Administration and commonly prescribed by primary care physicians, randomized trials for effectiveness, and trials and observational studies for adverse events.
DATA EXTRACTION
Data extraction was performed by one reviewer and checked by a second reviewer. Study quality was assessed by 2 independent reviewers. Strength-of-evidence assessment was done by group discussion.
DATA SYNTHESIS
High-strength evidence from 28 trials (only 3 of which were placebo-controlled) shows that colchicine, nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroids reduce pain in patients with acute gout. Moderate-strength evidence suggests that low-dose colchicine is as effective as high-dose colchicine and causes fewer gastrointestinal adverse events. Moderate-strength evidence suggests that urate-lowering therapy (allopurinol or febuxostat) reduces long-term risk for acute gout attacks after 1 year or more. High-strength evidence shows that prophylaxis with daily colchicine or NSAIDs reduces the risk for acute gout attacks by at least half in patients starting urate-lowering therapy, and moderate-strength evidence indicates that duration of prophylaxis should be longer than 8 weeks. Although lower urate levels reduce risk for recurrent acute attacks, treatment to a specific target level has not been tested.
LIMITATION
Few studies of acute gout treatments, no placebo-controlled trials of management of hyperuricemia lasting longer than 6 months, and few studies in primary care populations.
CONCLUSION
Colchicine, NSAIDs, and corticosteroids relieve pain in adults with acute gout. Urate-lowering therapy decreases serum urate levels and reduces risk for acute gout attacks.
