There is currently no consensus on its management in the Republic of Ireland. Recent trials have suggested that appropriate active management of metabolic acidosis through oral alkali therapy and modified diet can have a deterring impact on CKD progression. The potential benefits of treatment include preservation of bone health and improvement in muscle function; however,present data is limited. This review highlights the current evidence,available primarily from randomised control trials(RCTs) over the last decade,in managing the metabolic acidosis of CKD and outlines ongoing RCTs that are promising. An economic perspective is also briefly discussed to support decision-making.展开更多

However, to date there are no reports on the long-term hard endpoints (ESRD and death) of anti-HCV therapy [interferon-based therapy (IBT) or new direct-acting antivirals] in CKD patients. Direct-acting antivirals are not available in Taiwan’s singlepayer national health insurance database currently released for research. Therefore, we hypothesized that a retrospective analysis of the long-term outcomes of IBT in CKD patients will serve as a proxy for direct-acting antivirals to increase our understanding of progression to ESRD following HCV infection. AIM To evaluate the long-term outcomes (ESRD and death) of anti-HCV therapy, especially IBT, in HCV-infected patients with stage 1-5 CKD. METHODS We analyzed 93894 Taiwan Residents adults diagnosed with CKD and without HBV infection. Of these, 4.9% were infected with HCV. Of the 4582 HCV-infected CKD patients, 482 (10.5%) received IBT (treated cohort). They were matched 1:4 with 1928 untreated HCV-infected CKD patients (untreated cohort) by propensity scores and year, which further matched 1:2 by propensity scores with 3856 CKD patients without HCV infection (uninfected cohort). All participants were followed until the occurrence of ESRD, death, or the end of 2012. The association between HCV infection, IBT use, and risks of ESRD and death was analyzed using competing risk analysis. RESULTS Taking the uninfected cohort as a reference, the adjusted hazard ratios for ESRD, after adjusting for competing mortality, were 0.34 (0.14-0.84, P = 0.019) and 1.28 (1.03-1.60, P = 0.029) in the treated and untreated cohorts, respectively. The treated cohort had a 29%(0.54-0.92, P = 0.011) decrease in mortality compared to the untreated cohort, in which the mortality was 31%(1.18-1.45, P < 0.001) higher than in the uninfected cohort. The reduced risks of ESRD (0.14, 0.03–0.58, P = 0.007) and death (0.57, 0.41-0.79, P = 0.001) were greatest in HCV-infected CKD patients who received at least 4 mo of IBT, which accounted for 74% of the treated cohort.CONCLUSION Adequate anti-HCV therapy in CKD patients improves long-term renal and patient survival.展开更多

The reference population was all children (〈 18 years old) suffering from CKD and attending the tertiary paediatric nephrology clinic in Brunei Darussalam. Demographic (current age, age of diagnosis, gender, ethnicity), anthropometric (weight and height), diagnosis, laboratory data (serum creatinine and haemoglobin, urinalysis) and blood pressure were extracted from the patients’ clinical case notes and recorded using a data collection form.RESULTS: The study revealed a high national prevalence [736 per million child population (pmcp)] and incidence (91 pcmp) of CKD. If CKD was defned at Stage 1, 2, 3, 4 or 5, the associated prevalence fgures were 736, 132, 83, 50 and 33 pmcp. Glomerulonephritis accounted for 69% of all prevalent cases, followed by congenital abnormalities of kidney and urinary tract (20%) and tubulointerstitial diseases (8%). Minimal change disease being the most common histological diagnosis. The median age of diagnosis was 4.5 years, with congenital disease patients experiencing an earlier onset of diagnosis. A large proportion of patients were below the 5% percentile for height and weight. Non-glomerular diseases, adolescent and female patients were significantly associated with poor growth, but not glomerular filtration rate, age of diagnosis or steroid usage. CONCLUSION: Brunei has a high prevalence of chronic kidney disease in the paediatric population with glome-rulonephritis being the most common disease.展开更多

In patients with chronic disease, sleep disorders are more prevalent, with an additional morbidity and mortality burden. The complex and dynamic relationship between sleep disorders and chronic kidney disease(CKD) remain relatively little investigated. This article presents an overview of sleep disorders in patients with CKD, with emphasis on relevant pathophysiologic underpinnings and clinical presentations. Evidence-based interventions will be discussed, in the context of individual sleep disorders, namely sleep apnea, insomnia, restless leg syndrome and excessive daytime sleepiness. Limitations of the current knowledge as well as future research directions will be highlighted, with a final discussion of different conceptual frameworks of the relationship between sleep disorders and CKD.展开更多

Worldwide CKD is considered as the 16th leading cause of death and affects 8% - 16% of the population. CKD often goes unnoticed and is revealed as an incidental finding. Healthcare providers diagnose the condition as CKD based on persistent abnormal kidney function tests revealing kidney damage markers > 3 months, urine albumin creatinine ratio (UACR) > or equal to 30 mg/g per 24 hours, and GFR < 60 mL/min/1.73m<sup>2</sup>. In this article, we have discussed chronic kidney disease in terms of kidney physiology, chronic kidney disease pathophysiology, etiology, diagnosis, signs and symptoms, and management.展开更多

Usually, thermal therapy requires an infrared dry sauna. However, it is difficult for small clinics to acquire such an expensive and extensive system. The author assessed the efficacy of its substitution with hot water bottles. Moreover, there are no prior studies demonstrating the efficacy of thermal therapy in hemodialysis patients with chronic heart failure. Methods: The author evaluated plasma brain natriuretic peptide (BNP) levels in 98 hemodialysis patients in a clinic. A total of nine patients whose BNP levels were more than 500 pg/mL agreed to be enrolled in this study and received thermal therapy using hot water bottles. Results: Plasma BNP levels, a potential marker for CHF, tended to decrease (891 ± 448 pg/mL to 680 ± 339 pg/mL), but the difference was not significant (P = 0.0845). The oral temperature changed from 36.44℃± 0.45℃ to 37.04℃ ± 0.48℃ (+0.597℃, P < 0.0001). No side effects were experienced during the therapy. Moreover, most patients had an improvement in their symptoms and the ability to perform activities of daily living. Conclusion: Thermal therapy using hot water bottles is very safe and tends to reduce plasma BNP levels in hemodialysis patients with CHF.展开更多

The aim of this study is to evaluate the incidence, prevalence of epidemiological indicators (age, sex), and causes of chronic renal failure in children in Mashhad (one of the big cities of Iran). Methods: This is a cross-sectional study that was conducted on patients’ records over a seven-year period (2008-2014) in Doctor Sheikh Children’s Hospital of Mashhad. The inclusion criteria were all children under 20 years old diagnosed with ESRD, with a GFR less than 15 ml/min/1.73 m2 who were referred to the hospital during the study period. Patients’ information, such as age, gender, onset of dialysis, causes of constructing renal failure, and positive or negative antigen of hepatitis B was extracted from their records. Data were analyzed using SPSS 16 software. Results: A total of 326 patients were studied, of which, 56.4% were male. 45.1% were from 7 to 18 years. 56.4% of patients were on hemodialysis and others were on peritoneal dialysis. The most common cause of chronic renal failure in the study was respectively reflux nephropathy (32.9%), nephrotic syndrome (8.9%), neurogenic bladder (5.5%), stones (2.5%), glomerulopathy (2.1%) and cystinosis (1.5%) and (20.9%) had unknown cause. During the 7-year period of study considering the treatment outcomes, 69.3% of patients needed to continue the dialysis;10.4% underwent transplantation;10.4% unfortunately died despite of treatment and 1.5% were cured. Conclusions: It is hoped that considering the clinical symptoms of children with chronic renal failure and the diagnosis of the cause, we can reduce complications of the disease with a quick diagnosis and treatment, as well as appropriate follow-up.展开更多

This article describes renal replacement therapy (RRT) services in Qatar and their evolution in response to challenges posed by the growth of ESRD with reference to regional and international data. It covers the history of RRT, highlighting significant advances in chronological order, as well as providing an overview of the current status of RRT in the multicultural and socioeconomically diverse society that inhabits Qatar. Finally, it casts a glance into the future, predicting how RRT services will further evolve to address the current limitations.展开更多

The LA Dialysis and Transplant Registry was initiated in 1991, with the aim of collecting data on renal replacement therapy(RRT) from the 20 LA-affiliated countries. Since then, the Registry has revealed a trend of increasing prevalence and incidence of end-stage kidney disease on RRT, which is ongoing and is correlated with gross national income, life expectancy at birth, and percentage of population that is older than 65 years. In addition, the rate of kidney transplantation has increased yearly, with > 70% being performed from deceased donors. According to the numbers reported for 2013, the rates of prevalence, incidence and transplantation were(in patients per million population) 669, 149 and 19.4, respectively. Hemodialysis was the treatment of choice(90%), and 43% of the patients undergoing this treatment was located in Brazil; in contrast, peritoneal dialysis prevailed in Costa Rica, El Salvador and Guatemala. To date, the Registry remains the only source of RRT data available to healthcare authorities in many LA countries. It not only serves to promote knowledge regarding epidemiology of end-stage renal disease and the related RRT but also for training of nephrologists and renal researchers, to improve understanding and clinical application of dialysis and transplantation services. In LA, accessibility to RRT is still limited and it remains necessary to develop effective programs that will reduce risk factors, promote early diagnosis and treatment of chronic kidney disease, and strengthen transplantation programs.展开更多

The detrimental effect of elevated low-density lipoprotein (LDL) cholesterol and/or decreased HDL cholesterol on cardiovascular disease risk had been well established from previous studies.1 Recently, emerging evidences suggest that dyslipidemia may also be an important contributor to morbidity and mortality of chronic kidney disease (CKD), which has received more and more attention as the prevalence of CKD increases.展开更多

文摘BACKGROUND Hepatitis C virus (HCV) infection is a documented risk factor for chronic kidney disease (CKD) and progression to end-stage renal disease (ESRD). However, to date there are no reports on the long-term hard endpoints (ESRD and death) of anti-HCV therapy [interferon-based therapy (IBT) or new direct-acting antivirals] in CKD patients. Direct-acting antivirals are not available in Taiwan’s singlepayer national health insurance database currently released for research. Therefore, we hypothesized that a retrospective analysis of the long-term outcomes of IBT in CKD patients will serve as a proxy for direct-acting antivirals to increase our understanding of progression to ESRD following HCV infection. AIM To evaluate the long-term outcomes (ESRD and death) of anti-HCV therapy, especially IBT, in HCV-infected patients with stage 1-5 CKD. METHODS We analyzed 93894 Taiwan Residents adults diagnosed with CKD and without HBV infection. Of these, 4.9% were infected with HCV. Of the 4582 HCV-infected CKD patients, 482 (10.5%) received IBT (treated cohort). They were matched 1:4 with 1928 untreated HCV-infected CKD patients (untreated cohort) by propensity scores and year, which further matched 1:2 by propensity scores with 3856 CKD patients without HCV infection (uninfected cohort). All participants were followed until the occurrence of ESRD, death, or the end of 2012. The association between HCV infection, IBT use, and risks of ESRD and death was analyzed using competing risk analysis. RESULTS Taking the uninfected cohort as a reference, the adjusted hazard ratios for ESRD, after adjusting for competing mortality, were 0.34 (0.14-0.84, P = 0.019) and 1.28 (1.03-1.60, P = 0.029) in the treated and untreated cohorts, respectively. The treated cohort had a 29%(0.54-0.92, P = 0.011) decrease in mortality compared to the untreated cohort, in which the mortality was 31%(1.18-1.45, P < 0.001) higher than in the uninfected cohort. The reduced risks of ESRD (0.14, 0.03–0.58, P = 0.007) and death (0.57, 0.41-0.79, P = 0.001) were greatest in HCV-infected CKD patients who received at least 4 mo of IBT, which accounted for 74% of the treated cohort.CONCLUSION Adequate anti-HCV therapy in CKD patients improves long-term renal and patient survival.
文摘AIM: To determine epidemiology of Bruneian paediatric chronic kidney disease (CKD) patients and factors that affect growth and progression of disease.METHODS: A cross-sectional study conducted on all children below 18 years old who were diagnosed with CKD over a ten year period (2004 to 2013). The reference population was all children (〈 18 years old) suffering from CKD and attending the tertiary paediatric nephrology clinic in Brunei Darussalam. Demographic (current age, age of diagnosis, gender, ethnicity), anthropometric (weight and height), diagnosis, laboratory data (serum creatinine and haemoglobin, urinalysis) and blood pressure were extracted from the patients’ clinical case notes and recorded using a data collection form.RESULTS: The study revealed a high national prevalence [736 per million child population (pmcp)] and incidence (91 pcmp) of CKD. If CKD was defned at Stage 1, 2, 3, 4 or 5, the associated prevalence fgures were 736, 132, 83, 50 and 33 pmcp. Glomerulonephritis accounted for 69% of all prevalent cases, followed by congenital abnormalities of kidney and urinary tract (20%) and tubulointerstitial diseases (8%). Minimal change disease being the most common histological diagnosis. The median age of diagnosis was 4.5 years, with congenital disease patients experiencing an earlier onset of diagnosis. A large proportion of patients were below the 5% percentile for height and weight. Non-glomerular diseases, adolescent and female patients were significantly associated with poor growth, but not glomerular filtration rate, age of diagnosis or steroid usage. CONCLUSION: Brunei has a high prevalence of chronic kidney disease in the paediatric population with glome-rulonephritis being the most common disease.

文摘The relationship between nonalcoholic fatty liver disease(NAFLD)and chronic kidney disease(CKD)has gained considerable scientific interest in adults over the past few years.However,this association has recently emerged in children.Several published studies have suggested a role for NAFLD as a risk factor for CKD from the earliest age,with a potential influence of the major NAFLD risk polymorphisms,resulting in an increased risk of both cardiovascular and metabolic diseases.In view of the progressive course and increased cardiometabolic risk closely related to NAFLD and CKD,we focused on the link between these diseases in childhood.
文摘In 2002,the National Kidney Foundation Kidney Disease Outcomes Quality Initiative(NKF KDOQI)instituted new guidelines that established a novel chronic kidney disease(CKD)staging paradigm.This set of guidelines,since updated,is now very widely accepted around the world.Nevertheless,the authoritative United States Preventative Task Force had in August 2012acknowledged that we know surprisingly little about whether screening adults with no signs or symptoms of CKD improve health outcomes and that we deserve better information on CKD.More recently,the American Society of Nephrology and the American College of Physicians,two very well respected United States professional physician organizations were strongly at odds coming out with exactly opposite recommendations regarding the need or otherwise for"CKD screening"among the asymptomatic population.In this review,we revisit the various angles and perspectives of these conflicting arguments,raise unanswered questionsregarding the validity and veracity of the NKF KDOQI CKD staging model,and raise even more questions about the soundness of its evidence-base.We show clinical evidence,from a Mayo Clinic Health System Renal Unit in Northwestern Wisconsin,United States,of the pitfalls of the current CKD staging model,show the inexactitude and unpredictable vagaries of current CKD prediction models and call for a more cautious and guarded application of CKD staging paradigms in clinical practice.The impacts of acute kidney injury on CKD initiation and CKD propagation and progression,the effects of such phenomenon as the syndrome of late onset renal failure from angiotensin blockade and the syndrome of rapid onset end stage renal disease on CKD initiation,CKD propagation and CKD progression to end stage renal disease all demand further study and analysis.Yet more research on CKD staging,CKD prognostication and CKD predictions are warranted.Finally and most importantly,cognizant of the very serious limitations and drawbacks of the NKF K/DOQI CKD staging model,the need to individualize CKD care,both in terms of patient care and prognostication,cannot be overemphasized.
文摘Chronic Kidney Disease (CKD) is ongoing damage of the kidneys, which affects their ability to filter the blood the way they should. Worldwide CKD is considered as the 16th leading cause of death and affects 8% - 16% of the population. CKD often goes unnoticed and is revealed as an incidental finding. Healthcare providers diagnose the condition as CKD based on persistent abnormal kidney function tests revealing kidney damage markers > 3 months, urine albumin creatinine ratio (UACR) > or equal to 30 mg/g per 24 hours, and GFR < 60 mL/min/1.73m<sup>2</sup>. In this article, we have discussed chronic kidney disease in terms of kidney physiology, chronic kidney disease pathophysiology, etiology, diagnosis, signs and symptoms, and management.
文摘Chronic kidney disease(CKD)and hypertension(HTN)are closely associated with an overlapping and intermingled cause and effect relationship.Decline in renal functions are usually associated with a rise in blood pressure(BP),and prolonged elevations in BP hasten the progression of kidney function decline.Regulation of HTN by normalizing the BP in an individual,thereby slowing the progression of kidney disease and reducing the risk of cardiovascular disease,can be effectively achieved by the anti-hypertensive use of calcium channel blockers(CCBs).Use of dihydropyridine CCBs such as amlodipine(ALM)in patients with CKD is an attractive option not only for controlling BP but also for safely improving patient outcomes.Vast clinical experiences with its use as monotherapy and/or in combination with other anti-hypertensives in varied conditions have demonstrated its superior qualities in effectively managing HTN in patients with CKD with minimal adverse effects.In comparison to other counterparts,ALM displays robust reduction in risk of cardiovascular endpoints,particularly stroke,and in patients with renal impairment.ALM with its longer half-life displays effective BP control over 24-h,thereby reducing the progression of endstage-renal disease.In conclusion,compared to other classes of CCBs,ALM is an attractive choice for effectively managing HTN in CKD patients and improving the overall quality of life.
文摘In the last decades,a significant increase in the incidence of diabetic kidney disease(DKD)was observed concomitant with rising diabetes mellitus(DM)incidence.Kidney disease associated with DM in children and adolescents is represented by persistent albuminuria,arterial hypertension,progressive decline in estimated glomerular filtration rate to end-stage renal disease and increased cardiovascular and all-cause morbidity and mortality of these conditions.In medical practice,the common and still the“gold standard”marker for prediction and detection of diabetic kidney involvement in pediatric diabetes is represented by microalbuminuria screening even if it has low specificity to detect early stages of DKD.There are some known limitations in albuminuria value as a predictor biomarker for DKD,as not all diabetic children with microalbuminuria or macroalbuminuria will develop end-stage renal disease.As tubular damage occurs before the glomerular injury,tubular biomarkers are superior to the glomerular ones.Therefore,they may serve for early detection of DKD in both type 1 DM and type 2 DM.Conventional and new biomarkers to identify diabetic children and adolescents at risk of renal complications at an early stage as well as renoprotective strategies are necessary to delay the progression of kidney disease to end-stage kidney disease.New biomarkers and therapeutic strategies are discussed as timely diagnosis and therapy are critical in the pediatric diabetic population.
文摘Kidney disease after non-kidney solid organ transplantation(NKSOT)is a common post-transplant complication associated with deleterious outcomes.Kidney disease,both acute kidney injury and chronic kidney disease(CKD)alike,emanates from multifactorial,summative pre-,peri-and post-transplant events.Several factors leading to kidney disease are shared amongst solid organ transplantation in addition to distinct mechanisms unique to individual transplant types.The aim of this review is to summarize the current literature describing kidney disease in NKSOT.We conducted a narrative review of pertinent studies on the subject,limiting our search to full text studies in the English language.Kidney disease after NKSOT is prevalent,particularly in intestinal and lung transplantation.Management strategies in the peri-operative and post-transplant periods including proteinuria management,calcineurin-inhibitor minimization/sparing approaches,and nephrology referral can counteract CKD progression and/or aid in subsequent kidney after solid organ transplantation.Kidney disease after NKSOT is an important consideration in organ allocation practices,ethics of transplantation.Kidney disease after SOT is an incipient condition demanding further inquiry.While some truths have been revealed about this chronic disease,as we have aimed to describe in this review,continued multidisciplinary efforts are needed more than ever to combat this threat to patient and allograft survival.
文摘Introduction: The use of repeated thermal therapy for improving the symptoms of chronic heart failure (CHF) has been recently demonstrated. Usually, thermal therapy requires an infrared dry sauna. However, it is difficult for small clinics to acquire such an expensive and extensive system. The author assessed the efficacy of its substitution with hot water bottles. Moreover, there are no prior studies demonstrating the efficacy of thermal therapy in hemodialysis patients with chronic heart failure. Methods: The author evaluated plasma brain natriuretic peptide (BNP) levels in 98 hemodialysis patients in a clinic. A total of nine patients whose BNP levels were more than 500 pg/mL agreed to be enrolled in this study and received thermal therapy using hot water bottles. Results: Plasma BNP levels, a potential marker for CHF, tended to decrease (891 ± 448 pg/mL to 680 ± 339 pg/mL), but the difference was not significant (P = 0.0845). The oral temperature changed from 36.44℃± 0.45℃ to 37.04℃ ± 0.48℃ (+0.597℃, P < 0.0001). No side effects were experienced during the therapy. Moreover, most patients had an improvement in their symptoms and the ability to perform activities of daily living. Conclusion: Thermal therapy using hot water bottles is very safe and tends to reduce plasma BNP levels in hemodialysis patients with CHF.
文摘Background: An irreversible renal function impairment is called chronic renal failure (CRF) which finally leads to the “end-stage renal disease” (ESRD) and requires renal replacement therapies. The aim of this study is to evaluate the incidence, prevalence of epidemiological indicators (age, sex), and causes of chronic renal failure in children in Mashhad (one of the big cities of Iran). Methods: This is a cross-sectional study that was conducted on patients’ records over a seven-year period (2008-2014) in Doctor Sheikh Children’s Hospital of Mashhad. The inclusion criteria were all children under 20 years old diagnosed with ESRD, with a GFR less than 15 ml/min/1.73 m2 who were referred to the hospital during the study period. Patients’ information, such as age, gender, onset of dialysis, causes of constructing renal failure, and positive or negative antigen of hepatitis B was extracted from their records. Data were analyzed using SPSS 16 software. Results: A total of 326 patients were studied, of which, 56.4% were male. 45.1% were from 7 to 18 years. 56.4% of patients were on hemodialysis and others were on peritoneal dialysis. The most common cause of chronic renal failure in the study was respectively reflux nephropathy (32.9%), nephrotic syndrome (8.9%), neurogenic bladder (5.5%), stones (2.5%), glomerulopathy (2.1%) and cystinosis (1.5%) and (20.9%) had unknown cause. During the 7-year period of study considering the treatment outcomes, 69.3% of patients needed to continue the dialysis;10.4% underwent transplantation;10.4% unfortunately died despite of treatment and 1.5% were cured. Conclusions: It is hoped that considering the clinical symptoms of children with chronic renal failure and the diagnosis of the cause, we can reduce complications of the disease with a quick diagnosis and treatment, as well as appropriate follow-up.
文摘The economic development of Qatar alongside the resultant lifestyle changes in the last few decades has contributed to increasing rates of obesity, diabetes mellitus and hypertension with consequent increased incidence and prevalence of chronic kidney disease and end-stage-renal-disease (ESRD). This article describes renal replacement therapy (RRT) services in Qatar and their evolution in response to challenges posed by the growth of ESRD with reference to regional and international data. It covers the history of RRT, highlighting significant advances in chronological order, as well as providing an overview of the current status of RRT in the multicultural and socioeconomically diverse society that inhabits Qatar. Finally, it casts a glance into the future, predicting how RRT services will further evolve to address the current limitations.
文摘In 2015, 634387 million people(9% of the world's population) resided in Latin America(LA), with half of those populating Brazil and Mexico. The LA Dialysis and Transplant Registry was initiated in 1991, with the aim of collecting data on renal replacement therapy(RRT) from the 20 LA-affiliated countries. Since then, the Registry has revealed a trend of increasing prevalence and incidence of end-stage kidney disease on RRT, which is ongoing and is correlated with gross national income, life expectancy at birth, and percentage of population that is older than 65 years. In addition, the rate of kidney transplantation has increased yearly, with > 70% being performed from deceased donors. According to the numbers reported for 2013, the rates of prevalence, incidence and transplantation were(in patients per million population) 669, 149 and 19.4, respectively. Hemodialysis was the treatment of choice(90%), and 43% of the patients undergoing this treatment was located in Brazil; in contrast, peritoneal dialysis prevailed in Costa Rica, El Salvador and Guatemala. To date, the Registry remains the only source of RRT data available to healthcare authorities in many LA countries. It not only serves to promote knowledge regarding epidemiology of end-stage renal disease and the related RRT but also for training of nephrologists and renal researchers, to improve understanding and clinical application of dialysis and transplantation services. In LA, accessibility to RRT is still limited and it remains necessary to develop effective programs that will reduce risk factors, promote early diagnosis and treatment of chronic kidney disease, and strengthen transplantation programs.

文摘Acute kidney injury(AKI),characterized by acute renal dysfunction,is an increasingly common clinical problem and an important risk factor in the subsequent development of chronic kidney disease(CKD).Regardless of the initial insults,the progression of CKD after AKI involves multiple types of cells,including renal resident cells and immune cells such as macrophages.Recently,the involvements of macrophages in AKI-to-CKD transition have garnered significant attention.Furthermore,substantial progress has also been made in elucidating the pathophysiological functions of macrophages from the acute kidney to repair or fibrosis.In this review,we highlight current knowledge regarding the roles and mechanisms of macrophage activation and phenotypic polarization,and transdifferentiation in the development of AKI-to-CKD transition.In addition,the potential of macrophage-based therapy for preventing AKI-to-CKD transition is also discussed.
文摘Background:Renin-angiotensin system inhibitor and calcium channel blocker (CCB) are widely used in controlling blood pressure (BP) in patients with chronic kidney disease (CKD).We carried out a meta-analysis to compare the renoprotective effect of the combination of angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) and CCB (i.e.,ACEI/ARB + CCB) with ACEI/ ARB monotherapy in patients with hypertension and CKD.Methods:Publications were identified from PubMed,Embase,Medline,and Cochrane databases.Only randomized controlled trials (RCTs) of BP lowering treatment for patients with hypertension and CKD were considered.The outcomes of end-stage renal disease (ESRD),cardiovascular events,BP,urinary protein measures,estimated glomerular filtration rate (GFR),and adverse events were extracted.Results:Based on seven RCTs with 628 patients,ACEI/ARB + CCB did not show additional benefit for the incidence of ESRD (risk ratio [RR] =0.84;95% confidence interval [CI]:0.52-1.33) and cardiovascular events (RR =0.58;95% CI:0.21-1.63) significantly,compared with ACEI/ARB monotherapy.There were no significant differences in change from baseline to the end points in diastolic BP (weighted mean difference [WMD] =-1.28 mmHg;95% CI:-3.18 to-0.62),proteinuria (standard mean difference =-0.55;95% CI:-1.41 to-0.30),GFR (WMD =-0.32 ml/min;95% CI:-1.53 to-0.89),and occurrence of adverse events (RR =1.05;95% CI:0.72-1.53).However,ACEI/ARB + CCB showed a greater reduction in systolic BP (WMD =-4.46 mmHg;95% CI:-6.95 to-1.97),compared with ACEI/ARB monotherapy.Conclusion:ACEI/ARB + CCB had no additional renoprotective benefit beyond than what could be achieved with ACEI/ARB monotherapy.
文摘Dyslipidemia, including hypercholesterolemia, hypertriglyceridemia, and low high-densitylipoprotein (HDL) cholesterinemia, is a key risk factor to atherosclerosis. The detrimental effect of elevated low-density lipoprotein (LDL) cholesterol and/or decreased HDL cholesterol on cardiovascular disease risk had been well established from previous studies.1 Recently, emerging evidences suggest that dyslipidemia may also be an important contributor to morbidity and mortality of chronic kidney disease (CKD), which has received more and more attention as the prevalence of CKD increases.
文摘Growth retardation is a significant complication observed in pediatric renal transplant recipients,originating from a multifactorial etiology.Factors contributing to growth impairment encompass pre-transplant conditions such as primary kidney disease,malnutrition,quality of care,growth deficits at the time of transplantation,dialysis adequacy,and the use of recombinant human growth hormone.Additionally,elements related to the renal transplant itself,such as living donors,corticosteroid usage,and graft functioning,further compound the challenge.Although renal transplantation is the preferred renal replacement therapy,its impact on achieving final height and normal growth in children remains uncertain.The consequences of growth delay extend beyond the physi-ological realm,negatively influencing the quality of life and social conditions of pediatric renal transplant recipients,and ultimately affecting their educational and employment outcomes.Despite advancements in graft survival rates,growth retardation remains a formidable clinical concern among children undergoing renal transplantation.Major risk factors for delayed final adult height include young age at transplantation,pre-existing short stature,and the use of specific immunosuppressive drugs,particularly steroids.Effective management of growth retardation necessitates early intervention,commencing even before transplantation.Strategies involving the administration of recombinant growth hormone both pre-and post-transplant,along with protocols aimed at minimizing steroid usage,are important for achieving catch-up growth.This review provides a comprehensive outline of the multifaceted nature of growth retardation in pediatric renal transplant recipients,emphasizing the importance of early and targeted interventions to mitigate its impact on the long-term well-being of these children from birth to adolescence.INTRODUCTION Children with chronic kidney disease(CKD)endure frequent hospitalizations and ongoing treatment,which significantly affect their quality of life.One of the most noticeable effects of CKD in children is poor growth,with stunted height being a common sign of chronic malnutrition.Growth assessment involves regularly measuring weight and height/length and comparing these against z-score charts,along with other anthropometric indicators like head circumference and mid-upper arm circumference.Data from the North American Pediatric Renal Trials and Collaborative Studies(NAPRTCS)registry shows that over 35%of children enrolled had stunted growth at the time of admission,with growth impairment being more severe in younger children(58%in those aged under 1 year,compared to 22%in those aged over 12 years).Additionally,the same data revealed that growth impairment worsens as the severity of the disease increases.Although recent advances in science have enabled better outcomes for children with CKD,in resource-limited settings,numerous children are still deprived of achieving optimal growth owing to the disease and its related factors.Stunting is a key indicator of chronic growth impairment in children.A study by Wong et al[1]in the United States Renal Data System found that each SD decrease in height among children with stage V CKD is linked to a 14%increase in the risk of death[1].Similarly,research by Furth et al[2]using data from the NAPRTCS indicated that children with a height standard deviation score(SDS)of-2.5 face a relative hazard of death of 2.07.Stunting also correlates with increased hospitalizations.A study in the United States followed 1112 pediatric patients with end-stage renal disease from 1990 to 1995.It showed that children with severe or moderate growth failure had higher hospitalization rates compared to those with normal growth.Specifically,the relative risk for hospitalization was 1.14(95%CI:1.1-1.2)for those with moderate growth failure and 1.24(95%CI:1.2-1.3)for those with severe growth failure,even after adjusting for age,sex,race,cause,and duration of end-stage renal disease,and treatment type[2](dialysis or transplant).The growth of a child significantly affects his/her psychological and overall well-being as an adult.Short children are often embarrassed by peers,and it has been observed that height influences employment status,with unemployment being more prevalent among stunted individuals.Further,marital opportunities can be fewer among stunted individuals[3].Hence,all measures to achieve adequate growth should be attempted in children with CKD,regardless of whether they undergo transplantation.
