  • Tackling Dialysis Burden around the World: A Global Challenge

    • Abstract: CKD is a global problem that causes significant burden to the healthcare system and the economy in addition to its impact on morbidity and mortality of patients. Around the world, in both developing and developed economies, the nephrologists and governments face the challenges of the need to provide a quality and cost-effective kidney replacement therapy for CKD patients when their kidneys fail. In December 2019, the 3rd International Congress of Chinese Nephrologists was held in Nanjing, China, and in the meeting, a symposium and roundtable discussion on how to deal with this CKD burden was held with opinion leaders from countries and regions around the world, including Australia, Canada, China, Hong Kong, Singapore, Taiwan, the UK, and the USA. The participants concluded that an integrated approach with early detection of CKD, prompt treatment to slow down progression, promotion of home-based dialysis therapy like peritoneal dialysis and home HD, together with promotion of kidney transplantation, are possible effective ways to combat this ongoing worldwide challenge.

  • Bone Quality in Chronic Kidney Disease Patients: Current Concepts and
           Future Directions – Part II

    • Abstract: Background: Patients with chronic kidney disease (CKD) have an increased risk of osteoporotic fractures, which is due not only to low bone volume and mass but also poor microarchitecture and tissue quality. The pharmacological and nonpharmacological interventions detailed, herein, are potential approaches to improve bone health in CKD patients. Various medications build up bone mass but also affect bone tissue quality. Antiresorptive therapies strikingly reduce bone turnover; however, they can impair bone mineralization and negatively affect the ability to repair bone microdamage and cause an increase in bone brittleness. On the other hand, some osteoporosis therapies may cause a redistribution of bone structure that may improve bone strength without noticeable effect on BMD. This may explain why some drugs can affect fracture risk disproportionately to changes in BMD. Summary: An accurate detection of the underlying bone abnormalities in CKD patients, including bone quantity and quality abnormalities, helps in institution of appropriate management strategies. Here in this part II, we are focusing on advancements in bone therapeutics that are anticipated to improve bone health and decrease mortality in CKD patients. Key Messages: Therapeutic interventions to improve bone health can potentially advance life span. Emphasis should be given to the impact of various therapeutic interventions on bone quality.

  • Bone Quality in CKD Patients: Current Concepts and Future
           Directions – Part I

    • Abstract: Background: There is ample evidence that patients with CKD have an increased risk of osteoporotic fractures. Bone fragility is not only influenced by low bone volume and mass but also by poor microarchitecture and tissue quality. More emphasis has been given to the quantitative rather than qualitative assessment of bone health, both in general population and CKD patients. Although bone mineral density (BMD) is a very useful clinical tool in assessing bone strength, it may underestimate the fracture risk in CKD patients. Serum and urinary bone biomarkers have been found to be reflective of bone activities and predictive of fractures independently of BMD in CKD patients. Bone quality and fracture risk in CKD patients can be better assessed by utilizing new technologies such as trabecular bone score and high-resolution imaging studies. Additionally, invasive assessments such as bone histology and micro-indentation are useful counterparts in the evaluation of bone quality. Summary: A precise diagnosis of the underlying skeletal abnormalities in CKD patients is crucial to prevent further bone loss and fractures. We must consider bone quantity and quality abnormalities for management of CKD patients. Here in this part I, we are focusing on advances in bone quality diagnostics that are expected to help in proper understanding of the bone health in CKD patients. Key Messages: Assessment of bone quality and quantity in CKD patients is essential. Both noninvasive and invasive techniques for the assessment of bone quality are available.

  • Effect of Marital Status on Depression and Mortality among Patients with
           Chronic Kidney Disease from National Health and Nutrition Examination
           Survey 2005–2014

    • Abstract: Background: The relationship between marital status and CKD is rarely studied. We aimed to explore the effect of marital status on the depression and mortality of patients with CKD. Methods: The data sources came from the NHANES database during 2005–2014 and 3,865 participants were included in this study. We used logistic regression models to examine the relationship between marital status and depression of CKD patients. The Cox proportional hazard models were used to evaluate the association between marital status and mortality of CKD patients. Results: In terms of depression in CKD patients, unmarried patients had a worse situation than married patients. Meanwhile, after adjusting the covariables, unmarried patients had increased risk of depression (OR = 1.26, 95% CI: 1.01–1.57) compared with married CKD patients, especially in males (OR = 1.45, 95% CI: 1.02–2.06) and patients with more than college education level (OR = 12.4, 95% CI: 3.75–41.02). There was a significant relationship between marital status and mortality of general CKD patients (HR = 1.36, 95% CI: 1.17–1.58). Moreover, marriage showed a protective effect against death among male patients, patients with school graduate or less and more than college educational level, patients with high income, and patients in different estimated glomerular filtration rate groups. Conclusions: The use of large numbers of participants has revealed the effect of marital status on CKD patients. Unmarried ones had a higher risk of depression than married ones among CKD patients. Meanwhile, the risk of death was higher in unmarried ones than married ones among CKD patients in this study.

  • Hydroxychloroquine Inhibits Cardiac Conduction in Aged Patients with
           Nonmalaria Diseases

    • Abstract: Background: The COVID-19 pandemic has brought increased focus on hydroxychloroquine (HCQ), as doctors, the medical community, and policymakers around the world attempt to understand how the risks of HCQ weigh against unknown benefits. We aim to evaluate the effects of HCQ on cardiac conduction, thus contributing to the global understanding of implications of HCQ use. Methods: We reviewed 717 cases of nonmalaria patients treated with HCQ (302) or without HCQ (415) in our hospital from 2008 to 2019, analyzed the cardiac conduction recorded by electrocardiogram (122 vs. 180) including heart rate (HR), PR, and corrected-QT (QTc) intervals, and explored the relationship of cardiac conduction with age, HCQ dosage, HCQ duration, sex, and primary diseases in HCQ users. Results: The all-cause mortality is similar between HCQ and non-HCQ groups (4.0 vs. 4.3%, p = 0.85). Patients aged 45 years or older, not younger ones, have lower HR (80.1 ± 1.7 vs. 85.7 ± 1.8 bpm, p = 0.03) but longer PR (163 ± 3.4 vs. 146.6 ± 4.2 ms, p = 0.003) and QTc (417.8 ± 3.8 vs. 407.7 ± 2.7 ms, p = 0.03) in HCQ than those in non-HCQ. The age in the HCQ group is positively correlated with PR (R = 0.31, p #x3c; 0.01) and QTc (R = 0.34, p #x3c; 0.01) but not HR. HR, PR, and QTc are not related to HCQ dosage (0.1–0.6 g/day), HCQ duration (0.2–126 months), sex, primary diseases, and repeated exams. Conclusion: Age is the most important risk factor of HCQ on cardiac conduction in nonmalaria patients. Electrocardiogram monitoring is suggested in aged patients due to the effects of HCQ on HR, PR, and QTc.

  • The Role of CXCL12 in Kidney Diseases: A Friend or Foe'

    • Abstract: Background: Chemokines are a family of proteins mainly mediating the homing and migration of various cells. The CXC chemokine CXCL12 is a member of low-weight-molecular chemokines. In the kidney, CXCL12 is pivotal for renal development and exerts a modulatory effect in kidney diseases under different etiologic settings by binding with CXC chemokine receptor 4 (CXCR4) or CXC chemokine receptor 7 (CXCR7). Besides, CXCL12 also exerts homeostasis influence in diverse physical conditions and various pathological situations. Thus, we conclude the complicated relationship between CXCL12 and kidney diseases in this review. Summary: In renal development, CXCL12 contributes a lot to nephrogenesis and the formation of renal vasculature via correlating with CXCR4. CXCL12 also plays an essential role in renal recovery from acute kidney injury. However, the CXCL12/CXCR4 axis plays a dual regulatory role in the initiation and development of diabetic kidney disease as well as chronic allogeneic nephropathy after kidney transplantation through dialectical consideration. Additionally, the CXCL12/CXCR4 link is considered as a new risk factor for lupus nephritis and renal cell carcinoma. Key Messages: Plenty of studies have presented the influence of CXCL12 and the relation with corresponding receptors in diverse biological and pathological statuses. Simultaneously, some drugs and antagonists targeting CXCL12/CXCR4 axis effectively treat various kidney diseases. However, more researches are needed to explore thorough influence and mechanisms, providing more cues for clinical treatments.

  • Penicilliumin B Protects against Cisplatin-Induced Renal Tubular Cell
           Apoptosis through Activation of AMPK-Induced Autophagy and Mitochondrial

    • Abstract: Introduction: Acute kidney injury (AKI) is at a high prevalence in hospitalized patients, especially in those receiving chemotherapy. Cisplatin is the most widely used chemotherapy drug; however, with its side effects that include nephrotoxicity, it also exhibits a risk of inducing AKI. Importantly, recent studies have shown that autophagy plays a protective role in cisplatin-induced AKI. However, therapeutic strategies and candidate drugs for inducing activation of autophagy remain limited. Methods: In the present study, we adopted a novel candidate drug from a deep sea-derived Penicillium strain, penicilliumin B, to testify its protective role in cisplatin-induced renal tubular cell injury. Results: Penicilliumin B exhibited protection against cisplatin-induced apoptosis in cultured renal tubular epithelial cells and in cisplatin-treated mice. Moreover, penicilliumin B maintained normal mitochondrial morphology and inhibited the production of mitochondrial reactive oxygen species. Further studies demonstrated that penicilliumin B enhanced autophagic flux, promoted the activation of multiple autophagy-related proteins, such as mTOR, Beclin-1, ATG5, PINK1, and LC3B, and induced the degradation of p62. Interestingly, we also found penicilliumin B triggered phosphorylation of adenosine 5‘-monophosphate-activated protein kinase (AMPK), which is an upstream inducer of nearly all autophagy pathways and also an activator of mitochondrial biogenesis. These results suggest that AMPK may represent an activated site of penicilliumin B. Consistently, compound C, an AMPK inhibitor, significantly blocked the protective effects of penicilliumin B on mitochondria and apoptotic inhibition. Conclusion: Taken together, our findings indicate that penicilliumin B represents a novel AMPK activator that may provide protection against renal tubular cell apoptosis through activation of AMPK-induced autophagy and mitochondrial biogenesis.

  • Effect of Peer Mentoring on Quality of Life among CKD Patients: Randomized
           Controlled Trial

    • Abstract: Introduction: CKD is associated with decreased quality of life (QOL). Peer mentoring (PM) leads to improved QOL in various chronic diseases. The effectiveness of PM on QOL of patients with CKD has not been previously studied. We conducted a randomized clinical trial to test the effectiveness of face-to-face (FTF) and online mentoring by trained peers, compared with usual care, on CKD patients’ QOL. Methods: We randomized 155 patients in one of 3 groups: (1) FTF PM (n = 52), (2) online PM (n = 52), and (3) textbook only (n = 51). Peer mentors were patients with CKD, who received formal training through 16 h of instruction. Participants in all 3 groups received a copy of an informational textbook about CKD. Participants assigned to PM received either 6 months of FTF or online PM. The outcomes included time-related changes in domain scores of the Kidney Disease Quality of Life (KDQOL)-36 for each of the groups over the 18-month study period. Results: Compared with baseline, online PM led to improved scores in domains of the KDQOL-36 at 18 months: Effects of Kidney Disease (p = 0.01), Burden of Kidney Disease (p = 0.01), Symptoms and Problems of Kidney Disease (p = 0.006), SF-12 Physical Composite Summary (p = 0.001), and SF-12 Mental Composite Summary (p #x3c; 0.001). There were no statistically significant changes from baseline in domain scores of KDQOL-36 within the FTF PM and textbook-only groups. Conclusions: Among patients with CKD, online PM led to increased scores in domains of the KDQOL-36 at 18 months. The study was limited to English-speaking subjects with computer literacy and internet access.

  • Physical Function and Clinical Outcomes in Hemodialysis Patients: China
           Dialysis Outcomes and Practice Patterns Study

    • Abstract: Background: Hemodialysis (HD) patients usually have impaired physical function compared with the general population. Self-reported physical function is a simple method to implement in daily dialysis care. This study aimed to examine the association of self-reported physical function with clinical outcomes of HD patients. Methods: The Dialysis Outcomes and Practice Patterns Study (DOPPS) is a prospective cohort study. Data on 1,427 HD patients in China DOPPS5 were analyzed. Self-reported physical function was characterized by 2 items of “moderate activities limited level” and “climbing stairs limited level.” Demographic data, comorbidities, hospitalization, and death records were collected from patients’ records. Associations between physical function and outcomes were analyzed using COX regression models. Results: Compared to “limited a lot” in moderate activities, “limited a little” and “not limited at all” groups were associated with lower all-cause mortality after adjusted for covariates (HR: 0.652, 95% CI: 0.435–0.977, and HR: 0.472, 95% CI: 0.241–0.927, respectively). And, not limited in moderate activities was associated with lower risk of hospitalization than the “limited a lot” group after adjusted for covariates (HR: 0.747, 95% CI: 0.570–0.978). Meanwhile, compared to “limited a lot” in climbing stairs, “limited a little” and “not limited at all” groups were associated with lower all-cause mortality (HR: 0.574, 95% CI: 0.380–0.865 and HR: 0.472, 95% CI: 0.293–0.762, respectively) but not hospitalization after fully adjusted. Conclusion: Higher limited levels in self-reported physical function were associated with higher risk of all-cause mortality and hospitalization in HD patients.

  • SIRT1 Alleviates Aldosterone-Induced Podocyte Injury by Suppressing
           Mitochondrial Dysfunction and NLRP3 Inflammasome Activation

    • Abstract: Background: Podocyte injury contributes to progressive glomerulosclerosis. Previously, we demonstrated the important role of the NLR family pyrin domain containing 3 (NLRP3) inflammasome in mediating the podocyte injury induced by aldosterone. Silent mating type information regulation 2 homolog 1 (SIRT1) is an NAD+-dependent deacetylase that is associated with the regulation of cellular inflammation. However, whether the activation of the NLRP3 inflammasome in podocytes is regulated by SIRT1, and the mechanism involved, remains unknown. Methods: In this study, we detected SIRT1 expression in patients with podocyte disease and performed an aldosterone infusion model in podocyte-specific Sirt1 knockout mice. In cultured podocytes, we used plasmids to overexpress SIRT1 and treated the podocyte with aldosterone. Results: SIRT1 was significantly decreased in the glomeruli of patients with podocyte disease. Sirt1-deficient mice showed significant urinary albumin excretion after aldosterone infusion, and the severity of the glomerular injury was significantly greater in podocyte-specific Sirt1 knockout mice than in the wild-type mice. Moreover, podocyte conditional Sirt1 knockout aggravated NLRP3 inflammasome activation and mitochondrial dysfunction (MtD). In vitro, overexpression of SIRT1 inhibited NLRP3 activation, protected against MtD and podocyte injury. Conclusion: Taken together, these findings revealed a novel regulatory mechanism of the NLRP3 inflammasome by SIRT1 by promoting mitochondrial function, which provides some potential targets for the treatment of glomerular diseases.
