Project description:BackgroundSerum uric acid (UA) could exert neuro-protective effects against Alzheimer's disease (AD) via its antioxidant capacities. Many studies investigated serum UA levels in AD patients, but to date, results from these observational studies are conflicting.MethodsWe conducted a meta-analysis to compare serum UA levels between AD patients and healthy controls by the random-effects model. Studies were identified by searching PubMed, ISI Web of Science, EMBASE, and the Cochrane library databases from 1966 through July 2013 using the Medical Subject Headings and keywords without restriction in languages. Only case-control studies were included if they had data on serum UA levels in AD patients and healthy controls. Begg's funnel plot and Egger's regression test were applied to assess the potential publication bias. Sensitivity analyses and meta-regression were conducted to explore possible explanations for heterogeneity.ResultsA total of 11 studies met the inclusion criteria including 2708 participants were abstracted. Serum UA levels were not significantly different in AD patients compared to healthy controls (standardized mean difference (SMD) = -0.50; 95% confidence interval (CI): -1.23 to 0.22). Little evidence of publication bias was observed. Sensitivity analyses showed that the combined SMD was consistent every time omitting any one study, except only one study which greatly influenced the overall results. Meta-regression showed that year of publication, race, sample size, and mean age were not significant sources of heterogeneity.ConclusionOur meta-analysis of case-control studies suggests that serum UA levels do not differ significantly in AD patients, but there may be a trend toward decreased UA in AD after an appropriate interpretation. More well-designed investigations are needed to demonstrate the potential change of serum UA levels in AD patients.

Project description:BackgroundLower serum uric acid (UA) levels have been reported as a risk factor in Parkinson's disease (PD). However, the results have been inconsistent so far.ObjectivesThe aim of the present study was to clarify the potential relationship of uric acid with PD.MethodsComprehensive electronic search in pubmed, web of science, and the Cochrane Library database to find original articles about the association between PD and serum uric acid levels published before Dec 2015. Literature quality assessment was performed with the Newcastle-Ottawa Scale. Random-effects model was used to estimate the standardized mean differences (SMDs) with 95% confidence intervals (CIs). Heterogeneity across studies was assessed using I2 and H2 statistics. Sensitivity analyses to assess the influence of individual studies on the pooled estimate. Publication bias was investigated using funnel plots and Egger's regression test. Analyses were performed by using Review Manager 5.3 and Stata 11.0.ResultsThirteen studies with a total of 4646 participants (2379 PD patients and 2267 controls) were included in this meta-analysis. The current results showed that the serum UA levels in PD patients were significantly lower compared to sex and age-matched healthy controls (SMD: -0.49, 95% CI: [-0.67, -0.30], Z = 5.20, P < 0.001) and these results showed no geographic regional (Asia: SMD = -0.65, 95% CI [-0.84, -0.46], Z = 6.75, p <0.001; Non-Asia: SMD = -0.25, 95% CI [-0.43, -0.07], Z = 2.70, p = 0.007) and sex differences (women: SMD = -0.53, 95% CI [-0.70, -0.35], z = 5.98, p <0.001; men: SMD = -0.66, 95% CI [-0.87, -0.44], z = 6.03, p <0.001). Serum UA levels in middle-late stage PD patients with higher H&Y scales were significantly lower than early stage PD patients with lower H&Y scales (SMD = 0.63, 95% CI [0.36,0.89], z = 4.64, p <0.001).ConclusionsOur study showed that the serum UA levels are significantly lower in PD and the level is further decreased as the disease progresses. Thus it might be a potential biomarker to indicate the risk and progression of PD.

Project description:BackgroundPsoriasis is a chronic immune-mediated inflammatory skin disease associated with increase of some pro-inflammatory mediators. We wanted to investigate whether there is a relationship between psoriasis and visfatin, fetuin-A and pentraxin 3 (PTX3)-pro-inflammatory mediators implicated in the development of insulin resistance (IR), metabolic syndrome, and atherosclerosis.MethodsVisfatin, fetuin-A, and PTX3 concentrations were measured in 45 patients with plaque-type psoriasis and 45 healthy controls using enzyme-linked immunosorbent assay (ELISA).ResultsSerum levels of visfatin, fetuin-A, and PTX3 in patients with psoriasis were found to be higher than in healthy controls (P = 0.002, P = 0.009, P < 0.001, respectively). Psoriasis area and severity index (PASI) score correlated significantly with visfatin and fetuin-A levels (P = 0.011, P = 0.040, respectively). There was a significant positive correlation between visfatin and fetuin-A (P < 0.001). PTX3 levels were correlated positively with homeostasis model assessment (HOMA-IR), insulin, triglyceride (TG), and very low density lipoprotein cholesterol (VLDL; P = 0.009, P = 0.007, P = 0.023, P = 0.024, respectively).ConclusionsIncreased serum visfatin, fetuin-A, and PTX3 levels, and the presence of positive correlation between visfatin, fetuin-A, and PASI score, probably reflect the inflammatory state and IR seen in psoriasis.

Project description:The magnitude of the effect of fetuin-A and fetuin-B on non-alcoholic fatty liver disease (NAFLD) remains undefined. Therefore, the aim of this study was to synthesize previous findings to obtain a reliable estimation of this relationship. This study was registered in PROSPERO with the number CRD42019126314. Studies published not later than March 2019, examining the relationship between fetuin-A, fetuin-B, and NAFLD, were identified by a systematic search in the electronic databases of the Web of Science, PubMed, Embase, and Cochrane Library. Pooled estimates of standardized mean difference (SMD), calculated using the random-effects model in a meta-analysis, were applied to estimate the strength of the association between fetuin-A, fetuin-B, and NAFLD. Thirty publications were identified and analyzed based on specified inclusion criteria. Collectively, they consisted of 3800 NAFLD participants and 3614 controls. Compared with the controls, significant higher values of the fetuin-A (SMD = 0.83, 95% CI: 0.59 to 1.07, Z = 6.82, p < 0.001) and fetuin-B (SMD = 0.18, 95% CI: 0.02 to 0.33, Z = 2.27, p = 0.023) were observed in NAFLD patients. Meanwhile, in the subgroup analysis, the effect value of fetuin-A in the NASH group was significantly higher than that in the NAFL group (p = 0.036). The findings of this study suggest that elevated fetuin-A and fetuin-B may independently indicate the occurrence of NAFLD. Nevertheless, further research is needed to confirm these results.

Project description:Background and objectivesVascular calcifications predict cardiovascular disease, the major cause of death in renal transplant recipients (RTRs). We studied the determinants of fetuin-A, a potent circulating calcification inhibitor encoded by the AHSG gene, and tested its association with vascular calcifications and long-term survival and cardiovascular events (CVEs) in RTRs.Design, setting, participants, & measurementsTwo hundred seventy-seven prevalent RTRs from a single center were included. CVEs and deaths were prospectively recorded during a 5-year follow-up.ResultsIndependent determinants of lower serum fetuin-A levels were lower plasma cholesterol, the AHSG rs4918 G allele, and history of smoking. Low serum fetuin-A level was a determinant of aortic calcifications (assessed using spiral CT). Low fetuin-A levels (≤0.47 g/L, first quintile) were independently associated with CVEs and deaths (hazard ratio=1.83; 95% confidence interval, 1.07 to 3.04). The association was confirmed for all-cause mortality, and the major adverse cardiovascular endpoints were analyzed separately. Patients with low fetuin-A and high high-sensitivity C-reactive protein (>4.36 mg/L, fourth quintile) levels had a 3.5-fold increased risk of all-cause mortality and CVEs. In the presence of inflammation, CVE-free survival was influenced by common variants in the AHSG gene.ConclusionsThese data show that low fetuin-A levels are independently associated with aortic calcifications and a higher risk of CVEs and mortality. They support fetuin-A as a circulating biomarker able to identify RTRs at risk for vascular calcifications and CVEs.

Project description:IntroductionWilson's disease may lead to cirrhosis, but timely medical treatment could slow down its progression. Clinical markers helping early diagnosis are essential. Decreased fetuin-A concentration has been reported in cirrhosis of different etiologies. The aim of this study was to investigate whether decreased serum fetuin-A concentration could identify patients with Wilson's disease who developed cirrhosis.Materials and methodsIn this cross-sectional study we determined the serum fetuin-A concentration of 50 patients with Wilson's disease. We analyzed the data of patients with liver involvement, comparing cirrhotic and non-cirrhotic patients.ResultsAmong patients with liver involvement those with cirrhosis had significantly lower fetuin-A and albumin level, white blood cell and platelet count. Fetuin-A negatively correlated with disease duration, bilirubin level, positively with total protein and albumin concentration, but not with copper and ceruloplasmin concentrations or markers of systemic inflammation. In multivariate analysis with fetuin-A and the Nazer score or its parameters only fetuin-A was a significant determinant of having cirrhosis. In receiver operator curve analysis among patients with liver involvement the fetuin-A level of 523 μg/ml was associated with cirrhosis with 82% sensitivity and 87% specificity. The presence of the H1069Q mutation was not associated with alteration in fetuin-A concentration.ConclusionsThe serum concentration of fetuin-A is a sensitive marker of liver cirrhosis in Wilson's disease, independently of the H1069Q mutation, ceruloplasmin concentration or systemic inflammation.

Project description:BACKGROUND:Metabolic syndrome is a common extrapulmonary comorbidity in patients with chronic obstructive pulmonary disease (COPD). However, the reported relationship of COPD with dyslipidemia, an important component of metabolic syndrome, is ambiguous. The aim of this meta-analysis is to investigate the association between COPD and the serum levels of high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), total cholesterol (TC), and triglyceride (TG). METHODS:The PubMed and Embase databases were searched to find potential studies using the search terms of ("dyslipidemia" or "HDL" or "LDL" or "cholesterol" or "triglyceride") and COPD. We also performed subgroup analysis enrolling patients who were not receiving treatment for dyslipidemia. Mean differences (MD) with 95% confidence intervals (CI) were estimated with random effects models. RESULTS:A total of 11 studies comprising 615 cases and 471 controls were included in the study. No significant differences were found in the HDL (MD = -2.55, 95% CI [-6.03, 0.93], P = 0.15), LDL (MD = -2.25, 95% CI [-13.36, 8.86], P = 0.69), TC (MD = -2.69, 95% CI [-13.30, 7.92], P = 0.62), and TG (MD = 6.90, 95% CI [-2.81, 16.60], P = 0.16) levels of the 2 groups. However, subgroup analysis enrolling patients who were not receiving treatment for dyslipidemia showed that TG levels were higher in patients with stable COPD than in healthy individuals (MD = 16.35, 95% CI [5.90, 26.80], P = 0.002). CONCLUSIONS:Excluding the impact of hypolipidemic treatment on serum lipid profile, TG levels were higher in patients with COPD than in healthy individuals. This meta-analysis suggested that physicians should screen COPD patients for elevated TG levels to reduce the risk of cardiovascular morbidity and mortality.

Project description:BackgroundWe aim to conduct a comprehensive meta-analysis encompassing all studies to assess the efficacy of Vascepa in patients with diabetes mellitus (DM) in preventing or treating existing coronary artery disease (CAD).MethodsDigital databases were queried. Odds ratios (OR) were calculated for the following outcomes: composite outcome, all-cause mortality, and cardiovascular mortality.ResultsA total of 4 randomized control trials (33,092 patients; Vascepa n = 16586; Placebo n = 16506) were included in our analysis. The overall mean age was 64.3 years old (Vascepa = 64.3 years; Placebo = 64.3 years). The sample was 61.5% male (Vascepa = 60.8%; Placebo = 62.1%). In patients with DM, Vascepa was found to have no significant effect on the primary composite outcome (OR 0.97, 95%CI 0.91-1.04, p > 0.05), all-cause mortality (OR 0.96, 95%CI 0.90-1.03, p > 0.05), and cardiovascular mortality (OR 0.90, 95%CI 0.74-1.10, p > 0.05). Subgroup analysis by Vascepa type and treatment type was similarly non-significant.ConclusionOur study concluded that Vascepa did not affect cardiovascular outcomes in patients with DM.

Project description:Background and aimsPrevious studies reported that serum resistin levels were remarkably changed in patients with nonalcoholic fatty liver disease (NAFLD) but the conclusions were inconsistent. The aim of this study was to investigate accurate serum resistin levels in adult patients with NAFLD.MethodsA complete literature research was conducted in the PubMed, Embase, and Cochrane Library databases, and all the available studies up to 7 May 2020 were reviewed. The pooled standardized mean difference (SMD) values were calculated to investigate the serum resistin levels in patients with NAFLD and healthy controls.ResultsA total of 28 studies were included to investigate the serum resistin levels in patients with NAFLD. Patients with NAFLD had higher serum resistin levels than controls (SMD=0.522, 95% confidence interval [CI]: 0.004-1.040, I 2=95.9%). Patients with nonalcoholic steatohepatitis (NASH) had lower serum resistin levels than the healthy controls (SMD=-0.44, 95% CI: -0.83-0.55, I 2=74.5%). In addition, no significant difference of serum resistin levels was observed between patients with NAFL and healthy controls (SMD=-0.34, 95% CI: -0.91-0.23, I 2=79.6%) and between patients with NAFL and NASH (SMD=0.15, 95% CI: -0.06-0.36, I 2=0.00%). Furthermore, subgroup and sensitivity analyses suggested that heterogeneity did not affect the results of meta-analysis.ConclusionsThis meta-analysis investigated the serum resistin levels in adult patients with NAFLD comprehensively. Patients with NAFLD had higher serum resistin levels and patients with NASH had lower serum resistin levels than healthy controls. Serum resistin could serve as a potential biomarker to predict the development risk of NAFLD.

Project description:BackgroundConflicting results have been reported from studies evaluating serum uric acid (SUA) levels as an independent risk factor for cardiovascular mortality in patients with chronic kidney disease (CKD).MethodsWe systematically searched MEDLINE, Web of Science, and bibliographies of retrieved articles to identify studies reporting on the association between SUA levels and cardiovascular mortality in patients with CKD. Random-effects models were used to calculate the pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI).ResultsWe included 11 studies with an overall sample of 27,081 patients with CKD in this meta-analysis. By meta-analysis, restricted to 7 studies (n = 11,050), patients with the highest SUA were associated with an increased risk of cardiovascular mortality (HR 1.47, 95% CI 1.11-1.96) compared with patients with the lowest SUA. There was no indication of publication bias or significant heterogeneity (I2 = 40.4%; P = 0.109). Meta-analysis of 10 studies (n = 26,660) indicated that every 1 mg/dl increase in SUA levels increased a 12% risk in cardiovascular mortality (HR 1.12, 95% CI 1.02-1.24), with significant heterogeneity (I2 = 79.2%, P < 0.001).ConclusionsHigher SUA levels are associated with significantly increased risk of cardiovascular mortality in patients with CKD. More designed studies, especially randomized controlled trials, should be conducted to determine whether high SUA levels is a potentially modifiable risk factor for cardiovascular mortality in patients with CKD.
