Renin-angiotensin system inhibitors are important to the management of these conditions; however, their efficacy for advanced CKD remains uncertain.Summary: Angiotensin receptor-neprilysin inhibitors (ARNIs) have superior efficacy for heart failure (HF) management, as evidenced by landmark trials such as the PARADIGM-HF and PARAGON-HF, thus leading to its endorsement by various guidelines. Although direct evidence supporting the renal-protective effects of ARNI is lacking, post hoc analyses have suggested its potential to mitigate the decline of the estimated glomerular filtration rate and renal events, particularly in patients with HF with a relatively preserved ejection fraction. Mechanistically, ARNI augments the glomerular filtration rate by dilating glomerular arterioles, relaxing mesangial cells, and improving renal medullary blood flow, thereby mitigating interstitial fibrosis progression. ARNI also effectively addresses nondipper hypertension, particularly in salt-sensitive individuals, thereby reducing the cardiovascular risk.Key messages: Uncertainties regarding the efficacy and safety of ARNI for advanced renal failure (estimated glomerular filtration rate <30 mL/min) exist. Excessive hypotension associated with ARNI use may exacerbate the renal function decline, especially in older patients with comorbid HF with a reduced ejection fraction. Hence, vigilant blood pressure monitoring is essential to optimizing the renal benefits of ARNI and minimizing adverse effects. Evidence supporting the renal benefits of ARNI continues to evolve; therefore, ARNI could mitigate renal dysfunction in select patient populations. Further research should be performed to clarify the efficacy of ARNI for advanced renal failure and refine its therapeutic application for patients with concurrent HF and renal dysfunction.","PeriodicalId":17813,"journal":{"name":"Kidney & blood pressure research","volume":" ","pages":"916-932"},"PeriodicalIF":2.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142468941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 4 patients, next-generation sequencing using a nephrocalcinosis-nephrolithiasis panel was performed to determine the nature of the underlying disease. In addition, longitudinal analysis of renal function was performed in all patients.Results: Seven patients revealed carbonate apatite as the sole constituent of renal calculi. One patient showed a mixed composition of dicalcium phosphate dihydrate/carbonate apatite at first analysis yet in subsequent episodes also had calculi composed of pure carbonate apatite. Further molecular analysis displayed distal renal tubular acidosis in 2 of 4 patients who consented to sequencing. No known genetic defect could be found in the other two cases. In line with prior reports, decline of renal function was dependent on underlying disease. Distal renal tubular acidosis revealed a progressive course of renal failure, whereas other causes showed stable renal function in long term analysis.Conclusion: Nephrocalcinosis with nephrolithiasis is a rare condition with heterogeneous aetiology.

This uniform finding is similar to subcutaneous calcifications of various origins and might propose a general principle of tissue calcification.

Each day, urine was collected in 4 intervals (7:00-13:00 h, 13:00-19:00 h, 19:00-23:00 h, and 23:00-07:00 h). Plasma aldosterone was measured at 6:30 h, 12:30 h, and 18:30 h. Sodium intakes were estimated by various formulas using 3 timed urines of day 5-7.Results: During a 200-mmol daily sodium intake, sodium intake estimates based on three repeated timed urine samples and the Toft equation differed 10 [IQR: 3-14], 8 [6-19], 36 [16-49], and 20 [10-43] mmol from the actual intake for intervals 7:00-13:00 h, 13:00-19:00 h, 19:00-23:00 h, 23:00-7:00 h, respectively.

The aetiology of Liddle syndrome is missense or frameshift mutations in the SCNN1A, SCNN1B, or SCNN1G genes, which encode for the epithelial sodium channel subunits. Among these, mutations in the SCNN1A gene are very rare.Case presentation: A Liddle syndrome case caused by a SCNN1A mutation was reported from China. A 59-year-old proband had a 21-year history of chronic hypertension. His blood pressure was poorly controlled with various antihypertensive drugs, and hypokalaemia was found 8 years ago with no definite cause. At this visit, the patient presented with excessive renal potassium excretion and decreased renin activity in the postural stimulation test; however, his aldosterone level was normal. Subsequent genetic testing identified a missense mutation in SCNN1A (c.1475G>A), which encodes for a protein with an altered amino acid at position 492 (p.Arg492Gln). The pedigree investigation found that the older brother and son of the proband also have the same mutation. The patient's serum potassium returned to normal, and blood pressure control was significantly improved after being treated with triamterene.Conclusion: A middle-aged patient with Liddle syndrome was diagnosed. A new point mutation in the SCNN1A gene was detected in this patient, and the pathogenicity of this mutation was predicted using AlphaFold software, expanding the genetic mutation spectrum of Liddle syndrome. Genetic testing should be improved to exclude monogenic hypertension in patients with hypertension complicated with hypokalaemia.","PeriodicalId":17813,"journal":{"name":"Kidney & blood pressure research","volume":" ","pages":"831-838"},"PeriodicalIF":2.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142140388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weighted Gene Co-Expression Network Analysis (WGCNA) was performed to identify co-expression modules related to the second dose of COVID-19 mRNA vaccination and IgAN. Differentially expressed genes (DEGs) were screened, and a transcription factor (TF)-miRNA regulatory network and protein-drug interaction were constructed for the shared genes.Results: WGCNA identified one module associated with the second dose of COVID-19 mRNA vaccine and four modules associated with IgAN. Gene ontology (GO) analyses revealed enrichment of cell cycle-related processes for the COVID-19 mRNA vaccine hub genes and immune effector processes for the IgAN hub genes. We identified 74 DEGs for the second dose of COVID-19 mRNA vaccine and 574 DEGs for IgAN. Intersection analysis with COVID-19 vaccine-related genes led to the identification of two shared genes, TOP2A and CEP55. The TF-miRNA network analysis showed that hsa-miR-144 and ATF1 might regulate the shared hub genes.Conclusions: This study provides insights into the common pathogenesis of COVID-19 mRNA vaccination and IgAN.

We sought to characterize the association between abnormal cholesterol profiles and cardiovascular morbidity and mortality in this unique population.Methods: This retrospective cohort study was conducted at a single center and included all adult KTR, transplanted between January 2005 and April 2014. The primary outcome was major adverse cardiovascular events (MACE) while the secondary outcome was the composite outcome of MACE and all-cause mortality. Exposure to abnormal cholesterol levels was calculated using a time-weighted average calculation. MACE and mortality risk were analyzed using a multivariate time-varying Cox model.Results: The final cohort comprised 737 KTR, with a median follow-up of 2,920 days.

High LDL-C levels and MACE risk were correlated by multivariate analysis (HR 1.008 per mg/dL, 95% CI: 1.001-1.016), while low HDL-C levels were not significantly associated with MACE (HR 0.992 per mg/dL, 95% CI: 0.976-1.009).

Slope parameters and the areas under the curve of characteristic sections of pulse waves as well as the power spectrum of the pulse waves and their first and second derivatives were computed. Furthermore, the amplitude of volumetric change (AMP) was assessed. Duplex sonography served as a reference method.Results: In the comprehensive set of novel pulse wave parameters significant inter-arm differences were demonstrated and a significant delay of the systolic maximum at the fistula arm in comparison to the non-fistula arm (204 ± 3.4 vs. 162 ± 5.3 ms, p < 0.001) was proven. Unexpectedly, pulse wave velocity apparently did not differ between both arms (7.85 vs. 8.05 m/s at the fistula/non-fistula side, p = 0.942). The inter-arm differences of the slope parameters were more pronounced in forearm than in upper arm fistulas. Finally, we showed that the inter-arm difference of AMP correlated with volume flow (r = 0.326 with p = 0.017).Conclusion: Pulse waves as assessed by oscillometric pulse wave analysis have distinct features at fistula and non-fistula arms. This is due to enhanced arteriovenous flow, i.e. in both the brachial artery and the fistula vein. The analysis of those alterations has the potential to assess fistula function.","PeriodicalId":17813,"journal":{"name":"Kidney & blood pressure research","volume":" ","pages":"667-675"},"PeriodicalIF":2.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141457801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
