Adiponectin levels and the risk of hypertension: a systematic review and meta-analysis.

ABSTRACT: Animal studies and small controlled studies in humans suggest that adiponectin may regulate blood pressure via brain-mediated and endothelium-mediated mechanisms. We performed a systematic review and meta-analysis to evaluate the epidemiological evidence on plasma adiponectin levels and hypertension in free-living adult population. A systematic search of MEDLINE and EMBASE, up to February 2013, identified 43 nonprospective and 5 prospective studies that included 17 598 adults (8220 with hypertension; mean age 19-69 years; and mean body mass index 22-38 kg/m(2)). Two investigators independently extracted data on adiponectin levels by hypertension status and dose-response relationship. We used a random-effects model to compute the weighted mean difference in adiponectin levels between adults with hypertension and normotensive adults and a 2-stage generalized least-square trend methods to compute the odds ratio of hypertension per 1 µg/mL increase in adiponectin. Adults with hypertension had 1.64 µg/mL (95% confidence interval, -2.07, -1.21) lower adiponectin levels than normotensive adults. Every 1 µg/mL increase in adiponectin levels was associated with 6% reduced risk of hypertension (95% confidence interval, 0.92, 0.97). These findings were consistent across study design and characteristics, including age, sex, and body mass index (P>0.05). However, our meta-analysis was limited by unexplained large between-study heterogeneity, a small number of prospective studies, and selective reporting of dose-response data. In conclusion, epidemiological evidence suggests that plasma adiponectin level is a biomarker and possible mediator in the development of adiposity-related hypertension. The question remains as to adiponectin as a potential therapeutic target and its relationship with other adipokines in blood pressure regulation.

Project description:Background: The association between Aldehyde dehydrogenase II (ALDH-2) rs671 polymorphism and essential hypertension (EH) risk or blood pressure (BP) levels remains unclear. Objective: To systematically review the influence of the aldehyde dehydrogenase II rs671 polymorphism on essential hypertension risk and blood pressure levels. Methods: The PubMed, EMbase, Web of Science, Cochrane Library, CNKI and CBM databases were electronically searched to identify case-control or cohort studies published prior to July 2019 that examined the association between the rs671 polymorphism and the risk of essential hypertension or blood pressure levels. A meta-analysis was conducted with Stata 15.1 software. Results: Twenty-two articles were included. Among these articles, 20 incorporated 30 individual studies evaluating the association between the rs671 polymorphism and EH (11,051 hypertensive patients and 15,926 normotensive controls), and 8 incorporated 12 individual studies evaluating the association between the rs671 polymorphism and BP (20,512 subjects). The results of the meta-analysis showed that the mutation of the rs671 polymorphism was associated with a significantly decreased risk of EH in all models: allelic model (OR = 0.80, 95% CI: 0.73-0.87), homozygous model (OR = 0.71, 95% CI: 0.63-0.80), heterozygous model (OR = 0.79, 95% CI: 0.72-0.87), dominant model (OR = 0.79, 95% CI: 0.71-0.87), and recessive model (OR = 0.76, 95% CI: 0.68-0.85). In the stratified analyses, significant associations were found for males, drinkers and population-based studies. Simultaneously, the A carriers had lower SBP (WMD = -1.78, 95% CI: -3.02 to -0.53) and DBP (WMD = -1.09, 95% CI: -1.58 to -0.61) levels than individuals with the GG homozygote. Conclusion: The collective findings of this meta-analysis suggested that the ALDH-2 rs671 polymorphism represented an important genetic marker in the development of hypertension. Considering the overall quality of evidence and the relatively small pooled sample size, more well-conducted high-quality studies are required to verify the above conclusion. Systematic Review Registration Number: PROSPERO (CRD42019129746).
