Therefore, this cohort study aimed to investigate the prognostic value of ambulatory blood pressure (ABP) in patients with CKD and to determine the optimal range for ABP. In total, 1051 hospitalized patients with CKD were enrolled. The prognosis of patients with CKD was evaluated in terms of all-cause death, cardiovascular death, cardiovascular events, and renal events. Our results showed that systolic blood pressure (SBP) had a higher predictive value than diastolic blood pressure in the multivariate-adjusted models. Additionally, nighttime SBP was found to be the best predictor of prognosis in patients with CKD. Furthermore, when dividing the nighttime SBP into quartiles (quartile 1: <110 mmHg, quartile 2: 110-124 mmHg, quartile 3:124-139 mmHg, and quartile 4: ≥139 mmHg). Nighttime SBP ≥ 124 mmHg had an impact on prognosis in patients with CKD, nighttime SBP 124-139 mmHg: total mortality (hazard ratio [HR], 3.017 [95% confidence interval (CI): 1.367-6.660]), cardiovascular death (HR, 2.570 [95% CI, 1.744-6.151]), all cardiovascular events (HR, 2.401 [95% CI, 1.288-4.475]), and 110-124 mmHg had an impact on the renal prognosis (HR, 1.975 [95% CI, 1.311-2.976]). Therefore, nighttime SBP is an independent risk factor for CKD and a significant predictor of prognosis in patients with CKD. Furthermore, the prognosis of patients with CKD improved when the nighttime SBP was maintained below 124 mmHg; however, maintaining it below 110 mmHg can further lower the incidence of renal disease.</p>","PeriodicalId":13029,"journal":{"name":"Hypertension Research","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Piezo2 is a mechanosensitive cation channel and plays a major role in various biological and pathophysiological phenomena. We previously reported Piezo2 expression in mouse and rat kidneys and its alteration by dehydration and hypertension. To elucidate the alteration of Piezo2 expression and its consequences in a mouse model of diabetic kidney disease, we used high salt-fed male KK-A^y mice, an accelerated genetic model of diabetic kidney disease. KK-A^y mice exhibited marked obesity, hyperglycemia, elevated blood pressure, higher creatinine clearance, and overt albuminuria. Histopathological analysis revealed glomerular hypertrophy, mesangial expansion, macrophage infiltration, tubular vacuolization, and interstitial fibrosis. The mRNA and protein expression analyses revealed (1) increased fibronectin protein expression in the glomerular areas, (2) upregulated Piezo2 expression in the glomerular mesangial cells and interstitial region, (3) increased Piezo2 and the fibronectin-coding gene Fn1 mRNA, and (4) a strong correlation of Piezo2 expression with that of Fn1 in the kidneys of diabetic kidney disease mice. Piezo2 upregulation and fibronectin accumulation were alleviated by an angiotensin II receptor blocker. In accordance with these in vivo results, in vitro study demonstrated that Piezo2 overexpression increased fibronectin production in HEK293T cells. In conclusion, we demonstrated that Piezo2 expression was upregulated in glomerular mesangial cells in a mouse model of diabetic kidney disease. Our results suggest that Piezo2 contributes to the progression of diabetic kidney disease by mediating glomerular fibronectin production, leading to glomerulosclerosis. Hyperfiltration is crucial in the pathogenesis of diabetic kidney disease. We showed that Piezo2 expression is upregulated in mesangial cells of diabetic kidney disease mice with glomerular fibronectin accumulation. Piezo2 overexpression increased fibronectin production in HEK293T cells.

Two different sGC agonists, sGC stimulators and activators, can increase its enzymatic activity in reduced and oxidized/apo forms, respectively. With some sGC agonists being already in clinical use, drugs in this category are expected to become new therapeutic agents for various conditions, including hypertension.

Coefficient of variation (CoV) of pulse transit time-based BP was considered as very short-term BPV. The primary outcome was a composite of heart failure hospitalization or cardiac death.

Therefore, the present study investigated whether the association between daily salt intake and blood pressure among community-dwelling older adults, including the very old people, based on their physical frailty status. This cross-sectional study used data from the SONIC study, a cohort study on older adults, collected between 2010 and 2012. Daily salt intake was estimated from the brief self-administered diet history questionnaire. Participants were stratified by groups based on the use of antihypertensive medication and their physical frailty status. There were 1975 participants with an average age of 76.5 ± 6.5 years and 53.1% were female. No association was observed between daily salt intake and blood pressure among participants with physical frailty regardless of the use of antihypertensive medication. In contrast, an association was noted between daily salt intake and systolic blood pressure among the robust without antihypertensive medication group (β = 0.08, p = 0.038), and the odds ratios for systolic blood pressure ≥140 mmHg were significantly higher in the third and fourth quartiles of daily salt intake than in the first quartile (odds ratios = 1.78 and 1.71, respectively). The present results suggest that the physical frailty status needs to be considered when providing salt reduction guidance to older adults for blood pressure control, in order to prevent progression of frailty and maintain quality of life.

Reduced albumin uptake and increased internalization of endocytic receptor megalin in PTEC were found in both the clipped and contralateral kidneys of 2K-1C rats. Renal denervation (DNx) or hydralazine treatment restored these parameters. Moreover, DNx, but not hydralazine, reduced serum creatinine and recovered podocyte numbers in the contralateral kidney of 2K-1C rats. Thus, our data suggest that renal nerves and high arterial pressure contribute to decreased albumin reabsorption by cellular redistribution of megalin in PTEC, while renal nerves remarkably drive glomerular dysfunction in renovascular hypertension, independently of their effect on blood pressure.
