Gut dysbiosis may be a potentially modifiable risk factor for HTN. However, the characteristics of gut microbiota in Chinese populations with HTN remain to be determined. Methods: We systematically searched for studies comparing the gut microbial in HTN with healthy controls in databases. The cut-off date was December 30, 2021. Semiquantitative analysis and meta-analysis with standardized mean differences of the alteration in gut microbiota were carried out. Results: A total of 16 studies involving 2,372 patients with HTN and 849 controls were included, covering 16 Chinese provinces or regions. The present study supports that compared to healthy population, the diversity of patients with HTN is significantly compromised, while richness is overall preserved. To be specific, a significant increase of the Firmicutes (F)/Bacteroidetes (B) ratio is considered as a special parameter of gut microbiota in HTN patients. The increased abundance of phylum Firmicutes, genus Megasphaera, Escherichia_Shigella, and Klebsiella while the lower abundance of phylum Bacteroidetes, genus Bifidobacterium, Faecalibacterium, Roseburia, and Ruminococcus may be associated with HTN. The gut microbial metabolism in HTN was more abundant in lipopolysaccharide biosynthesis, membrane transport, and steroid degradation. Conclusions: Variation in gut microbial parameters is likely associated with Chinese patients with HTN. Further investigations should distinguish geographical and ethnic characteristics to develop in-depth knowledge of the underlying mechanisms by which gut dysbiosis contributes to HTN.","PeriodicalId":17810,"journal":{"name":"Kidney and Blood Pressure Research","volume":"20 1","pages":"433 - 447"},"PeriodicalIF":0.0,"publicationDate":"2022-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76030733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: PubMed was searched to identify randomized sham-controlled trials from inception through August 2021. The endpoints were changes in 24-h ambulatory BP or office BP. This meta-analysis was performed by calculating the weighted mean difference (WMD) with 95% confidence interval (CI) using the random-effects model when the I2 index was <50%. A fixed-effects model was used when the I2 index was ≥50%. Results: A total of 1,297 patients were included in 8 randomized, sham-controlled trials in this meta-analysis. Intravascular RDN reduced 24-h ambulatory systolic BP (SBP) −3.02 (WMD, 95% CI: −4.95, −1.10, p < 0.01) and diastolic BP (DBP) −1.66 (WMD, 95% CI: −2.44, −0.88, p < 0.001) mm Hg, respectively. In the studies using first-generation catheters, the WMDs of 24-h ambulatory SBP and DBP changes between intravascular RDN and sham control were −2.67 (95% CI: −5.08, −0.27; p < 0.05; I2 = 0%, p = 0.53) and −0.82 (95% CI: −2.19, 0.56; p > 0.05; I2 = 0%, p = 0.64) mm Hg. In the studies using second-generation catheters, the WMDs of 24-h ambulatory SBP and DBP changes between intravascular RDN and sham control were −3.14 (95% CI: −5.94, −0.33, p < 0.05; I2 = 71%, p = 0.008) and −2.06 (95% CI: −3.02, −1.11, p < 0.001; I2 = 50%, p = 0.09) mm Hg. Intravascular RDN using second-generation catheters reduced office SBP −6.30 (WMD, 95% CI: −7.67, −4.93, p < 0.001; I2 = 43%, p = 0.14) and DBP −3.88 (WMD, 95% CI: −4.44, −3.33, p < 0.001; I2 = 42%, p = 0.14) mm Hg, respectively.

Recent data suggest that almost half of the elders have CKD. It is now clear that CKD is accompanied, in the early stages, by cognitive impairment, together with depression and subtle abnormalities in motor control (such as gait and balance alterations). Summary: Several data suggest a link between brain dopamine and kidney diseases. Metabolic syndrome and diabetes can affect dopamine neuron survival (leading to Parkinson’s disease). Several uremic toxins in CKD (uric acid, indoxyl sulfate) and trace elements accumulating in CKD (aluminum, manganese) can also modify the dopaminergic system. Hormones produced by the kidney such as vitamin D are neuroprotective for dopamine neurons. Dopaminergic drugs are useful for the treatment of a common sleep disorder in CKD, the restless legs syndrome. However, experiments on animal models of CKD show conflicting results regarding a modification of dopamine neurons. Key Messages: Several observations suggest a limited relevance of the dopaminergic system in CKD-related cognitive impairment. However, a common sleep disturbance in CKD, the restless legs syndrome, improves with dopaminergic drugs. Therefore, it remains to be established the role of the dopamine system in subtle motor dysfunction observed in CKD, such as tremors, gait alterations, and central sleep apnea.","PeriodicalId":17810,"journal":{"name":"Kidney and Blood Pressure Research","volume":"25 1","pages":"493 - 505"},"PeriodicalIF":0.0,"publicationDate":"2022-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84649360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lang","doi":"10.1159/000524050","DOIUrl":"https://doi.org/10.1159/000524050","url":null,"abstract":"Background/Aims: Vasopressin is a powerful stimulator of vascular calcification, augmenting osteogenic signaling in vascular smooth muscle cells (VSMCs) including upregulation of transcription factors such as core-binding factor α-1 (CBFA1), msh homeobox 2 (MSX2), and SRY-Box 9 (SOX9), as well as of tissue-nonspecific alkaline phosphatase (ALPL). Vasopressin-induced osteogenic signaling and calcification require the serum- and glucocorticoid-inducible kinase 1 (SGK1). Known effects of SGK1 include upregulation of Na+/H+ exchanger 1 (NHE1). NHE1 further participates in the regulation of reactive oxygen species (ROS). NHE1 has been shown to participate in the orchestration of bone mineralization. The present study, thus, explored whether vasopressin modifies NHE1 expression and ROS generation, as well as whether pharmacological inhibition of NHE1 disrupts vasopressin-induced osteogenic signaling and calcification in VSMCs. Methods: Human aortic smooth muscle cells (HAoSMCs) were treated with vasopressin in the absence or presence of SGK1 silencing, SGK1 inhibitor GSK-650394, and NHE1 blocker cariporide. Transcript levels were determined by using quantitative real-time polymerase chain reaction, protein abundance by Western blotting, ROS generation with 2′,7′-dichlorofluorescein diacetate fluorescence, and ALP activity and calcium content by using colorimetric assays. Results: Vasopressin significantly enhanced the NHE1 transcript and protein levels in HAoSMCs, effects significantly blunted by SGK1 inhibition with GSK-650394 or SGK1 silencing. Vasopressin increased ROS accumulation, an effect significantly blocked by the NHE1 inhibitor cariporide. Vasopressin further significantly increased osteogenic markers CBFA1, MSX2, SOX9, and ALPL transcript levels, as well as ALP activity and calcium content in HAoSMCs, all effects significantly blunted by SGK1 silencing or in the presence of GSK-650394 or cariporide. Conclusion: Vasopressin stimulates NHE1 expression and ROS generation, an effect dependent on SGK1 and required for vasopressin-induced stimulation of osteogenic signaling and calcification of VSMCs.","PeriodicalId":17810,"journal":{"name":"Kidney and Blood Pressure Research","volume":"1 1","pages":"399 - 409"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82689714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite investigations, the molecular mechanisms behind FSGS development remain to be more clarified. By a comprehensive analysis of an FSGS-related array set, the aim of this study was to unravel the top pathways and molecules involved in the pathogenesis of this disorder. Methods: FSGS-related microarray dataset (GSE129973) from the Gene Expression Omnibus database was quality checked, analyzed, and its differentially expressed genes (DEGs) (log2 fold change > 1) were used for the construction of a protein-protein interaction (PPI) network (STRING). The degree of centrality was considered to select the hub molecules in the network. The weighted gene co-expression network analysis (WGCNA) was utilized to construct co-expression modules. Hub molecules were selected based on module membership and gene significance values in the disease’s most correlated module. After spotting the key molecules considering both strategies, their expression pattern was checked in other FSGS microarray datasets. Gene ontology and Reactome pathway enrichment analyses were performed on the DEGs of the related module. Results: After quality checking, normalization, and analysis of the dataset, 5,296 significant DEGs, including 2,469 upregulated and 2,827 downregulated DEGs were identified. The WGCNA algorithm clustered the DEGs into nine independent co-expression modules. The disease most correlated module (black module) was recognized and considered for further enrichment analysis. The immune system, cell cycle, and vesicle-mediated transports were among the top enriched terms for the identified module’s DEGs. The immune system, cell cycle, and vesicle-mediated transports were among the top enriched terms for the black module’s DEGs. The key molecules (BMP-2 and COL4A1) were identified as common hub molecules extracted from the two methods of PPI and the co-expressed networks. The two identified key molecules were validated in other FSGS datasets, where a similar pattern of expression was observed for both the genes. Conclusions: Two hub molecules (BMP-2 and COL4A) and some pathways (vesicle-mediated transport) were recognized as potential players in the pathogenesis of FSGS.","PeriodicalId":17810,"journal":{"name":"Kidney and Blood Pressure Research","volume":"2 1","pages":"410 - 422"},"PeriodicalIF":0.0,"publicationDate":"2022-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73883755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Quantitative real-time polymerase chain reaction and Western blotting were used to detect the levels of genes and proteins. In vitro assays, including colony formation, 5-ethynyl-2′-deoxyuridine, flow cytometry, transwell assays, and in vivo tumor formation, were conducted to investigate the effects of circ_0037866 on RCC tumorigenesis. Dual-luciferase reporter assay, RNA pull-down, and RNA immunoprecipitation assay were used to confirm the interaction between miR-384 and circ_0037866 or Chromobox 5 (CBX5). Results: Circ_0037866 is a stable circRNA and was found to be increased in RCC tissues and cells. Functionally, circ_0037866 silencing suppressed RCC cell survival, invasion, and migration in vitro, and impeded RCC cell tumorigenesis in the subcutaneous xenograft model. Mechanistically, circ_0037866 could function as a sponge for miR-384 to elevate the expression of its target CBX5. Furthermore, a series of rescue experiments showed that miR-384 inhibition reversed the anticancer effects of circ_0037866 knockdown on RCC cells; besides that, miR-384 restoration suppressed RCC cell growth and mobility, which were attenuated by CBX5 overexpression.

The purpose of this study was to characterize the ureteral calculi patients with hydronephrosis-caused CysC changes in renal function. Methods: To better reflect the changes of renal function, we constructed models of ureteral obstruction in rats to mimic the hydronephrosis caused by human ureteral calculi. Moreover, our study included 200 patients diagnosed with ureteral calculi in our hospital between June 2017 and 2018. We compared the estimated glomerular filtration rate using different equations based on CysC and/or serum creatinine (SCr). Results: We found that the expression of CysC and SCr increased with the prolonged obstruction time by enzyme linked immunosorbent assay. Moreover, quantitative real-time polymerase chain reaction, Western blot and immunohistochemistry further demonstrated that the expression of CysC increases with the degree of hydronephrosis. Among 200 patients with ureteral calculi, 40 (20.0%) had no hydronephrosis, 110 (55.0%) had mild hydronephrosis, 32 (16.0%) had moderate hydronephrosis and 18 (9.0%) had severe hydronephrosis. As the degree of hydronephrosis increased, the expression of neutrophil percentage, CysC, blood urea nitrogen, SCr and serum uric acid also increased. Multivariate analyses demonstrated that only CysC was an independent risk factor for hydronephrosis (p = 0.003). In addition, CysC and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) CysC equation showed the highest veracity in renal function estimation of patients with hydronephrosis caused by ureteral calculus. Conclusion: For patients with hydronephrosis caused by ureteral calculi, CysC better reflects the changes in renal function, and the CKD-EPI CysC equation has the highest accuracy.","PeriodicalId":17810,"journal":{"name":"Kidney and Blood Pressure Research","volume":"64 1","pages":"109 - 121"},"PeriodicalIF":0.0,"publicationDate":"2019-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73401039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tölle, K.

Arterial stiffness (AS) – usually expressed with pulse wave velocity (PWV) – is an established independent predictor of cardiovascular risk beyond the traditional risk factors. Higher PWV values are frequently observed in patients with ESRD. Due to the intrinsic physiologic relationship between PWV and prevailing arterial pressure, PWV can change without relevant changes in the arterial wall structure, and thus an individual pressure-independent expression of PWV is essential. Methods: The study is a single-center observational study. Repeated measurements of blood pressure (BP) and pulse wave analysis were performed during each dialysis session of 1 week. Aortic PWV was then adjusted to 120 mm Hg central systolic BP (PWV120) based on individually determined relationship. PWV120 values were compared between single sessions. Calculation of the PWV120 was performed retrospectively. Results: Fifty-four subjects were included, 61.1% of whom were male. The median age was 75.5 years, and median dialysis vintage was 33.1 months. Mean systolic/diastolic BP was 121.4/70.5 mm Hg, and the median heart rate was 64.6 beats/min. Mean PWV was 10.9 m/s, and mean PWV120 was 11.3 m/s. PWV120 did not change across single dialysis session during 1 week, while systolic, diastolic BP, PWV, and ultrafiltration volume differed significantly. Discussion/Conclusions: Our data suggest that true AS does not change in the short-term course in dialysis patients. The observed changes in PWV are rather associated with BP change due to intrinsic pressure dependence. Our analytical approach represents a novel method for this purpose, which is easy in performance and also applicable for large interventional trials and clinical practice.","PeriodicalId":17810,"journal":{"name":"Kidney and Blood Pressure Research","volume":"6 1","pages":"51 - 60"},"PeriodicalIF":0.0,"publicationDate":"2019-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90522389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
