Cardiovascular complications are of particular clinical relevance because of their morbidity and mortality; however, unclear is why they occur so frequently in patients with ADPKD and whether they are related to the genotypes. Methods: We extracted and retrospectively analyzed clinical data on patients with ADPKD who underwent echocardiography and whose genotype was confirmed by genetic testing between April 2016 and December 2020. We used next-generation sequencing to compare cardiac function, structural data, and the presence of cardiac valvular disease in patients with 1 of 3 genotypes: PKD1, PKD2, and non-PKD1, 2. Results: This retrospective study included 65 patients with ADPKD. Patients were divided into 3 groups: PKD1, n = 32; PKD2, n = 12; and non-PKD1, 2, n = 21. The prevalence of mitral regurgitation (MR) was significantly higher in the PKD1 group than in the PKD2 and non-PKD1, 2 group (46.9% vs. 8.3% vs. 19.0%, respectively; p = 0.02). In contrast, no significant difference was found for other cardiac valve complications. Conclusion: This study found a significantly higher prevalence of MR in patients with the PKD1 genotype than in those with the PKD2 or non-PKD1, 2 genotypes. Physicians may need to perform echocardiography earlier and more frequently in patients with ADPKD and the PKD1 genotype and to control fluid volume and blood pressure more strictly in these patients to prevent future cardiac events.","PeriodicalId":17830,"journal":{"name":"Kidney Diseases","volume":"34 1","pages":"246 - 252"},"PeriodicalIF":3.7,"publicationDate":"2021-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76992277","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}

Most physiological metabolism of the kidney depends on oxygen, so it is very sensitive to oxygen. An increasing pool of evidence suggests that hypoxia is involved in almost all acute and chronic kidney diseases (CKDs). Vascular damage, tubular injury, and fibrosis are the main pathologies associated during hypoxia. Hypoxia-inducible factors (HIFs) are the main mediators during hypoxia, but their functions remain controversial. This article reviewed recent studies and described its mechanisms on renoprotection. Summary: HIF is degraded rapidly during under normal oxygen. But under hypoxia, HIFs accumulate and many target genes are regulated by HIFs. Homeostasis during injury is maintained through these genes. Pretreatment of HIF can protect the kidney from acute hypoxia and can improve repair, but HIF’s role in CKD and in renal tumor is still controversial. Due to its mechanism in kidney disease, many drugs toward HIFs are widely researched, even some of which have been used in clinical or in clinical research. Key Messages: In this review, we described the known physiological mechanisms, target genes, and renal protective roles of HIFs, and we discussed several drugs that are researched due to such renal protective roles.","PeriodicalId":17830,"journal":{"name":"Kidney Diseases","volume":"52 1","pages":"44 - 56"},"PeriodicalIF":3.7,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84312650","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}

{"title":"Longitudinal Follow-Up and Outcomes for Chinese Patients with Stage 1–4 Chronic Kidney Disease","authors":"Jinwei Wang, J. Lv, Kevin He, Fang-Yu Wang, B. Gao, Ming-hui Zhao, Luxia Zhang","doi":"10.1159/000519190","DOIUrl":"https://doi.org/10.1159/000519190","url":null,"abstract":"Introduction: Understanding heterogeneity in the prognosis of chronic kidney disease (CKD) has implications in management of patients. We aimed to evaluate the comparative risk of end-stage kidney disease (ESKD), cardiovascular (CV) events, and death among patients with CKD in China. Methods: In total, 3,700 patients with CKD stage 1–4 were recruited from 39 clinical centers in China between 2011 and 2016. New occurrence of ESKD, CV events, and all-cause mortality was recorded until the end of 2017. The crude incidence rate was calculated for each outcome. Ratios of incidence between different outcomes were generated with 95% confidence interval (CI) estimated by 1,000 times of bootstrapping. Multivariable adjusted Cox regression models accounting for competing risk between the outcomes were used to evaluate the association of risk factors with the outcomes. Results: The population mean age was 50 ± 14 years, with 58.2% male and 60.3% of glomerulonephritis. After a median follow-up of 4.65 years (interquartile range [IQR]: 3.71–5.60 years) for ESKD, 4.76 years (IQR: 3.97–5.76 years) for CV events, and 4.84 years (IQR: 3.97–5.76 years) for death, the incidence rates of the 3 outcomes were 3.1, 1.5, and 0.92/100 patient-years, respectively. The ratio for the incidence of ESKD and CV events was 2.15 (95% CI: 1.87, 2.53) and that for incidence of ESKD and death was 3.41 (95% CI: 2.88, 4.08). Significant differences regarding the ratios were detected through levels of age, history of CV disease, the estimated glomerular filtration rate (eGFR), urine albumin-to-creatinine ratio (uACR), and etiology of CKD. In the Cox regression model adjusting for traditional CV and kidney-specific risk factors, older age was associated with a higher risk of CV events and death but a lower risk of ESKD (hazard ratios [HRs] = 1.45 [95% CI: 1.29, 1.64], 1.48 [95% CI: 1.29, 1.70], and 0.78 [95% CI: 0.73, 0.84] per 10 year increase, respectively). By comparison, reduced eGFR was associated with a higher risk of ESKD and death, rather than CV events (HRs = 3.62 [95% CI: 2.96, 4.43], 1.30 [95% CI: 1.02, 1.66], and 1.22 [95% CI: 0.99, 1.49] per 30.26 mL/min/1.73 m2 increase, respectively). Similar patterns were seen for increased uACR (HRs = 1.42 [95% CI: 1.30, 1.55], 1.17 [95% CI: 1.05, 1.30], and 1.07 [95% CI: 0.99, 1.17] per 1 natural log-transformed value increase, respectively). Conclusion: ESKD was more likely to occur than CV events and death in the population with CKD stage 1–4 in China. Traditional risk factors contributed differently to the comparative risk of the outcomes.","PeriodicalId":17830,"journal":{"name":"Kidney Diseases","volume":"8 1","pages":"72 - 81"},"PeriodicalIF":3.7,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84258159","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 the last decade, a growing number of new therapeutic strategies focused on reversing the immunosuppressive status of tumor microenvironments (TMEs), to reprogram the TME to be normal, and to further activate the antitumor functions of immune cells. Most of the “hot tumors” are encompassed with M2 macrophages promoting tumor growth, and the accumulation of M2 macrophages into tumor islets leads to poor prognosis in a wide variety of tumors. Summary: Therefore, how to uncover more immunosuppressive signals and to reverse the M2 tumor-associated macrophages (TAMs) to M1-type macrophages is essential for reversing the immunosuppressive state. Except for reeducation of TAMs in the cancer immunotherapy, macrophages as central effectors and regulators of the innate immune system have the capacity of phagocytosis and immune modulation in macrophage-based cell therapies. Key Messages: We review the current macrophage-based cell therapies that use genetic engineering to augment macrophage functionalities with antitumor activity for the application of novel genetically engineered immune cell therapeutics. A combination of TAM reeducation and macrophage-based cell strategy may bring us closer to achieving the original goals of curing cancer. In this review, we describe the characteristics, immune status, and tumor immunotherapy strategies of macrophages to provide clues and evidences for future macrophage-based immune cell therapies.","PeriodicalId":17830,"journal":{"name":"Kidney Diseases","volume":"82 1","pages":"26 - 43"},"PeriodicalIF":3.7,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79697240","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}
