Efficacy of prednisone combined with mycophenolate mofetil for immunoglobulin A nephropathy with moderate-to-severe renal dysfunction

BACKGROUND Immunoglobulin A nephropathy(IgAN)is a common form of chronic glomer-ulonephritis.Currently,IgAN is one of the main causes of chronic renal failure in China;its prognosis varies greatly between patients,with renal function at the time of diagnosis and prognosis being strongly correlated.Mycophenolate mofetil(MMF)is a drug with a good immunomodulatory effect and is commonly used clinically.However,its effects in IgAN have not yet been clearly demonstrated.Therefore,herein,we retrospectively compared the effectiveness and safety of prednisone alone or combined with MMF for the treatment of primary IgAN with moderate-to-severe renal impairment.METHODS Between January 2011 and December 2020,200 patients with moderate-to-severe IgAN were included in this study,all of whom were admitted to Wuxi People's Hospital affiliated with Nanjing Medical University.All patients underwent a renal puncture biopsy,which revealed primary IgAN with a glomerular filtration rate(GFR)of 30–60 mL/min.The patients were divided into a glucocorticoid therapy group(GTG)and an immunosuppressive therapy group(ITG)according to the different treatment regimens,with 100 patients in each group.Based on general treatments,such as angiotensin-converting enzyme inhibitors/angiotensin receptor blockers,patients in the GTG were administered prednisone 0.5–0.8 mg/(kg·d^(-1))for 4–8 wk,which was reduced by 5 mg every two weeks until the maintenance(30 mg/d)dose was reached and maintained for 12 mo.In the ITG,MMF was administered at 1.0 g/d for 6–12 mo,followed by a maintenance dosage of 0.5 g/d for 12 mo.Age,sex,blood pressure,24-h urinary egg white measurement,serum creatinine(Scr),blood uric acid,blood albumin,blood potassium(K),hemoglobin,GFR,alanine aminotransferase,total cholesterol(T-CHO),fasting blood glucose,and body mass index were recorded.The 24-h urinary protein,Scr,and GFR levels were recorded 3,6,9,and 12 mo after treatment.Follow-up data were also collected.RESULTS No discernible differences existed between the two groups in terms of age,sex,blood pressure,creatinine,24-h urinary protein level,GFR,or other biochemical indicators at the time of enrollment.Both regimens significantly reduced the 24-h urinary protein quantitation and stabilized renal function.Nine months after treatment,the 24-h urinary protein and Scr of the ITG decreased more significantly than those of the GTG.By the 12th month of treatment,the 24-h urinary protein and Scr in both groups continued to decrease compared to those by the 9th month.In addition,the overall response rate in the ITG was significantly higher than that in the GTG.The occurrence of side effects did not vary significantly between the two regimens;however,endpoint events were significantly more common in the GTG than in the ITG.The follow-up time for the GTG was noticeably lower than that for the ITG.CONCLUSION Prednisone combined with MMF was effective for the treatment of IgAN with moderate-to-severe renal dysfunction.

Interplay between metabolic dysfunction-associated fatty liver disease and renal function: An intriguing pediatric perspective

Over recent years,the nomenclature of non-alcoholic fatty liver disease has undergone significant changes.Indeed,in 2020,an expert consensus panel proposed the term“Metabolic(dysfunction)associated fatty liver disease”(MAFLD)to underscore the close association of fatty liver with metabolic abnormalities,thereby highlighting the cardiometabolic risks(such as metabolic syndrome,type 2 diabetes,insulin resistance,and cardiovascular disease)faced by these patients since childhood.More recently,this term has been further replaced with metabolic associated steatotic liver disease.It is worth noting that emerging evidence not only supports a close and independent association of MAFLD with chronic kidney disease in adults but also indicates its interplay with metabolic impairments.However,comparable pediatric data remain limited.Given the progressive and chronic nature of both diseases and their prognostic cardiometabolic implications,this editorial aims to provide a pediatric perspective on the intriguing relationship between MAFLD and renal function in childhood.

Efficacy and Safety of Niaoduqing Particles for Delaying Moderate-to-severe Renal Dysfunction： A Randomized, Double-blind, Placebo-controlled, Multicenter Clinical Study

Background： Chronic kidney disease （CKD） with moderate-to-severe renal dysfunction usually exhibits an irreversible course, and available treatments for delaying the progression to end-stage renal disease are limited. This study aimed to assess the efficacy and safety of the traditional Chinese medicine, Niaoduqing particles, for delaying renal dysfunction in patients with stage 3b-4 CKD.Methods： The present study was a prospective, randomized, double-blind, placebo-controlled, naulticentcr clinical trial. Frorn May 2013 to December 2013,300 CKD patients with an estimated glomerular filtration rate （eGFR） between 20 and 45 ml ＂rain ~＂ 1.73 m 2, aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces. Patients were randomized in a 1：1 ratio to either a test group, which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks, or a control group, which was administered a placebo using the same methods. The primary endpoints were changes in baseline serum creatinine （Scr） and eGFR after completion of treatment. The primary endpoints were analyzed using Student＇s t-test or Wilcoxon＇s rank-sum test. The present study reported results based on an intention-to-treat （ITT） analysis. Results： A total of 292 participants underwent the ITT analysis. At 24 weeks, the median （interquartile range） change in Scr was 1.1 （-13.0-24.1） and 11.7 （-2.6-42.9） p, mol/L for the test and control groups, respectively （Z = 2.642, P = 0.008）, and the median change in eGFR was -0.2 （-4.3-2.7） and -2.2 （-5.7-0.8） ml.min-1·1.73 m-2, respectively （Z = -2.408, P = 0.016）. There were no significant differences in adverse events between the groups. Conclusions： Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD. This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.

Two novel VPS33B mutations in a patient with arthrogryposis,renal dysfunction and cholestasis syndrome in China's Mainland

Arthrogryposis,renal dysfunction and cholestasis(ARC)syndrome is a rare genetic disorder and has not been described in China.We present a female infant with neonatal intrahepatic cholestasis from a Chinese family with ARC syndrome.All 23 coding exons and flanking introns of the VPS33B gene were amplified and sequenced using peripheral lymphocyte genomic DNA of the patient and her parents.Genetic testing revealed two novel mutations(c.1033delA and c.1567C>T)in the VPS33B gene.The patient is a compound heterozygote and her parents were heterozygous for each of the mutations.

Acute renal dysfunction in patients with alcoholic hepatitis

Acute renal dysfunction is common in patients with alco-holic hepatitis(AH).Its presence leads to higher mortality in these patients.Despite advances in medical care,the outcome has changed little over the past decades.Studies using Pentoxifylline and molecular adsorbent recirculation system have shown encouraging data in small studies.Further larger well designed studies are needed to assess these modalities of treatment for the treatment of AH.

Renal dysfunction in patients with cirrhosis: Where do we stand?

Patients with cirrhosis and renal failure are high-risk patients who can hardly be grouped to form precise instructions for diagnosis and treatment. When it comes to evaluate renal function in patients with cirrhosis,determination of acute kidney injury(AKI),chronic kidney disease(CKD) or AKI on CKD should be made. First it should be excluded the prerenal causes of AKI. All cirrhotic patients should undergo renal ultrasound for measurement of renal resistive index in every stage of liver dysfunction and urine microscopy for differentiation of all causes of AKI. If there is history of dehydration on the ground of normal renal ultrasound and urine microscopy the diuretics should be withdrawn and plasma volume expansion should be tried with albumin. If the patient does not respond,the correct diagnosis is HRS. In case there is recent use of nephrotoxic agents or contrast media and examination shows shock,granular cast in urinary sediment and proteinuria above 0.5 g daily,acute tubular necrosis is the prominent diagnosis. Renal biopsy should be performed when glomerular filtration rate is between 30-60 mL/min and there are signs of parenchymal renal disease. The acute renalfunction is preferable to be assessed with modified AKIN. Patients with AKIN stage 1 and serum creatinine ≥ 1.5 mg/dL should be at close surveillance. Management options include hemodynamic monitoring and management of fluid balance and infections,potentially driving to HRS. Terlipressin is the treatment of choice in case of established HRS,administered until there are signs of improvement,but not more than two weeks. Midodrine is the alternative for therapy continuation or when terlipressin is unavailable. Norepinephrine has shown similar effect with terlipressin in patients being in Intensive Care Unit,but with much lower cost than that of terlipressin. If the patient meets the requirements for transplantation,dialysis and transjugular intrahepatic portosystemic shunt are the bridging therapies to keep the transplant candidate in the best clinical status. The present review clarifies the latest therapeutic modalities and the proposed recommendations and algorithms in order to be applied in clinical practice.

Nephroprotective activity of Solanum xanthocarpum fruit extract against gentamicin-induced nephrotoxicity and renal dysfunction in experimental rodents

Objective:To evaluate nephroprotective potential of Solarium xanthocarpum(S.xanthocarpum) fruit extract(SXE) against gentamicin(GM) induced nephrotoxicity) and renal dysfunction. Methods:Twenty-four Wistar rats were divided into four groups(n=6).Control rats that received normal saline(i.p.) and 0.5%carboxymethyl cellulose(p.o.) per day lor 8 d.Nephrotoxicity was induced in rats by intraperitoneal administration of GM(100 mg/kg/d for 8 d) and were treated with SXE(200 and 400 mg/kg/d(p.o.) for 8 d).Plasma and urine urea and creatinine,kidney weight,urine output,blood urea nitrogen,renal enzymatic and non-enzymatic antioxidants and lipid peroxidation was evaluated along with histopathological investigation in various experimental groupsof rats.Results:It was observed that the GM treatment induced significant elevation(P【0.001) in plasma and urine urea,creatinine,kidney weight,blood urea nitrogen, renal lipid peroxidation along with significant decrement(P【0.001) in urine output,renal enzymatic and non-enzymatic antioxidants.SXE 200 and 400 mg/kg treatment to GM treated rats recorded significant decrement(up to P【0.001) in plasma and mine urea and creatinine, renal lipid peroxidation along with significanl increment(up to P【0.001) in renal enzymatic and non-enzvmatic antioxidants.Histological obsenatioiis of kidney tissues too correlated with the biochemical obsenatioiis.Conclusions:These finding powerfully supports that S,xanthocarpum fruit extract acts in the kidney as a potent scavenger of free radicals to prevent the toxic effects of GM both in the biochemical and histopathological parameters and thus validates its elhnomedicinal use.

Beta-blocker therapy in elderly patients with renal dysfunction and heart failure

OBJECTIVE To assess the role of beta-blockers(BB)in patients with chronic kidney disease(CKD)aged≥75 years.METHODS AND RESULTS From January 2008 to July 2014,we included 390 consecutive patients≥75 years of age with ejection fraction≤35%and glomerular filtration rate(GFR)≤60 m L/min per 1.73 m^2.We analyzed the relationship between treatment with BB and mortality or cardiovascular events.The mean age of our population was 82.6±4.1 years.Mean ejection fraction was 27.9%±6.5%.GFR was 60-45 m L/min per 1.73 m^2 in 50.3%of patients,45-30 m L/min per 1.73 m^2 in 37.4%,and<30 m L/min per 1.73 m^2 in 12.3%.At the conclusion of follow-up,67.4%of patients were receiving BB.The median follow-up was28.04(IR:19.41-36.67)months.During the study period,211 patients(54.1%)died and 257(65.9%)had a major cardiovascular event(death or hospitalization for heart failure).BB use was significantly associated with a reduced risk of death(HR=0.51,95%CI:0.35-0.74;P<0.001).Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD:stage IIIa(GFR=30-45 m L/min per 1.73 m^2;HR=0.47,95%CI:0.26-0.86,P<0.0001),stage IIIb(GFR 30-45 m L/min per 1.73 m^2;HR=0.55,95%CI:0.26-1.06,P=0.007),and stages IV and V(GFR<30 m L/min per 1.73 m~2;HR=0.29,95%CI:0.11-0.76;P=0.047).CONCLUSIONS The use of BB in elderly patients with HFr EF and renal impairment was associated with a better prognosis.Use of BB should be encouraged when possible.

Global longitudinal strain is superior to ejection fraction for detecting myocardial dysfunction in end-stage renal disease with hyperparathyroidism

BACKGROUND The estimation of left ventricular ejection fraction(LVEF)by 2D echocardiography(2D-ECHO)is the most used tool to assess LV systolic function(LVSF).Global longitudinal strain(GLS)has recently been suggested as a superior method for several evaluations.This study explored the association and prevalence of LV systolic dysfunction(LVSD)by using these methods in patients with end-stage renal disease(ESRD)and severe hyperparathyroidism(SHPTH);both associated with cardiovascular events(CEs).AIM To evaluate the myocardial function in patients with ESRD and SHPTH by using the GLS and LVEF measured through conventional 2D-ECHO.METHODS In 62 patients with ESRD and SHPTH,asymptomatic,and without a history of CEs,LVSF was evaluated by 2D-ECHO,obtaining the EF,by the Simpson biplane method,and GLS by speckle tracking.RESULTS The total patients with ESRD had a preserved LVEF(>50%)but abnormal GLS(<13.55%).Additionally,multivariate analysis showed an independent association of GLS and serum parathyroid hormone(PTH),LV mass index,and hemoglobin.Also,PTH was independently associated with lateral e'wave and tricuspid regurgitation velocity.CONCLUSION In patients with SHPTH linked to ESRD,the use of GLS by 2D-ECHO is a more sensitive tool than LVEF for detecting LVSD.

Two novel mutations in the VPS33B gene in a Chinese patient with arthrogryposis,renal dysfunction and cholestasis syndrome 1:A case report

BACKGROUND The VPS33B(OMIM:608552)gene is located on chromosome 15q26.1.We found a female infant with autosomal recessive arthrogryposis,renal dysfunction and cholestasis syndrome 1(ARCS1)caused by mutation in VPS33B.The child was diagnosed with ARCS1(OMIM:208085)after the whole exome sequencing revealed two heterozygous mutations(c.96+1G>C,c.242delT)in the VPS33B gene.CASE SUMMARY We report a Chinese female infant with neonatal cholestasis disorder,who was eventually diagnosed with ARCS1 by genetic analysis.Genetic testing revealed two new mutations(c.96+1G>C and c.242delT)in VPS33B,which is the causal gene.The patient was compound heterozygous,and her parents were both heterozygous.CONCLUSION This study extends the mutational spectrum of the VPS33B gene to provide a molecular basis for the etiological diagnosis of ARCS1 and for genetic counseling of the family.

Urine immune profiling by measurement of multiple cytokine/chemokine mRNA levels in renal allograft dysfunction

Background: An accurate diagnosis of cause of acute renal graft dysfunction is crucial for the optimal management of transplant recipients. Currently available tests are either insensitive or nonspecific, or are invasive, such as allograft biopsy. During last decade, attempts have been made in search of non invasive markers for the evaluation of cause of graft dysfunction. We studied a set of genes expressed on cytotoxic T Lymphocytes and those related to functioning of regulatory or helper T cells. Methods: We obtained 108 urine samples from 108 renal allograft recipients at the time of graft biopsy done for the evaluation of cause of graft dysfunction. RNA was extracted from urinary cells and messenger RNA (mRNA) encoding perforin, granzyme B (GB), FoxP3, CD3?, CXCR3, TGF-?, CTLA4, PI-9, IL-10, TNF?, T-bet and 18SrRNA measured with the use of quantitative real time polymerase chain reaction (RT-PCR). The levels of expression of genes were correlated with the biopsy findings and the results compared among different groups. Renal allograft biopsies at this institution are performed when there is unexplained rise in serum creatinine of >20% from the baseline value and reported according to Banff classification. SPSS v10.0 used for analy-sis.Results: The mRNA copy numbers of GB, Perforin, FoxP3, CD3, CXCR3, TGF-?, CTL A4, PI9, IL-10, TNF?, and T-bet were log transformed and mean (± SD) levels studied. The expression of all studied genes were compared between ‘nonspecific biopsy findings’ and other specific diagnoses. GB, Perforin, FoxP3, TGF-?, CD3?, CTLA4 CXCR3 and T-bet were higher in acute cellular rejection (ACR), whereas, TGF-? was also found higher in infection, and PI-9 in chronic allograft nephropathy (CAN) and borderline rejection group. Conclusion: Measurement of mRNA levels for genes like GB, Perforin, FoxP3, TGF-β, CD3?, CTLA4, CXCR3 and T-bet in urine samples offers a non invasive means of diag-nosing cause of graft dysfunction.

Underestimation of chronic renal dysfunction after liver transplantation: ICEBERG study

AIM: To compare prevalence of chronic renal dysfunction(CRD) according to serum creatinine(sCr) vs estimated glomerular filtration rate(e GFR) among maintenance liver transplant patients.METHODS: The ICEBERG study was an observational, retrospective, cross-sectional, and multicenter study. Consecutive adult patients(aged 18 years or older) with liver transplantation(LT) performed at least two years previously were recruited. Multi-organ transplant recipients were excluded. Chronic renal dysfunction was defined according to sCr based criteria in routine clinical practice(≥ 2 mg/d L) and eGFR using MDRD-4 equation(< 60 m L/min per 1.73 m2). Agreement between sCr definition and e GFR assessment was evaluated using the Kappa index. Cox regression analysis was applied to identify predictive factors for developing CRD after LT.RESULTS: A total of 402 patients were analyzed(71.6% males). Mean ± SD age at transplant was 52.4 ± 9.8 years. Alcoholic cirrhosis without hepatocellular carcinoma was the most common reason for LT(32.8%). Mean time since LT was 6.9 ± 3.9 years. Based on sCr assessment, 35.3% of patients(95%CI: 30.6-40.0) had CRD; 50.2%(95%CI: 45.3-55.1) according to e GFR. In 32.2% of cases, sCr assessment had underestimated CRD. Multivariate analysis showed the following factors associated with developing CRD: eGFR < 60 m L/min per 1.73 m2 at three months post-transplant [hazard ratio(HR) = 4.76; 95%CI: 2.78-8.33; P < 0.0001]; calcineurin inhibitor use(HR = 2.31; 95%CI: 1.05-5.07; P = 0.0371); male gender(HR = 1.98; 95%CI: 1.09-3.60; P = 0.0260); and ≥ 10 years post-transplantation(HR = 1.95; 95%CI: 1.08-3.54; P = 0.0279).CONCLUSION: Seven years after LT, CRD affected half our patients, which was underestimated by s Cr. An e GFR < 60 m L/min per 1.73 m2 three months post-LT was predictive of subsequent CRD.

Gender Difference of Cadmium- induced Renal Tubular Dysfunction for Inhabitants in Toyama,Japan

Objective The aim of the present study mas to compare the gender difference for cadmium-induced renal tubular dysfunction between the male and female inhabitants. Methods Urinary β2-microglobulin was measured in 299 male (94%) and 342 female (92%) inhabitants aged 54-72 years,and the development of renal tubular dysfunction for 11 years was studied in the 62 married couples from them. Results A significantly higher cumulative incidence was found in both men and women in cadmium-polluted area,showing 68. 4% in men and 64. 8% in women compared to 15. 3% in men and 5. 9% in women in the reference areas. Relative risk of renal tubular dysfunction in females (11. 0) was higher than males (4. 5). The ratios of urinary β2-microglobulin and glucose were higher in women than those in men in both the cadmium-polluted areas and the reference areas. Conclusion Although almost identical incidences were detected between men and women, the changes in excretion of β2-microglobulin and glucose was greater in women than those in men. These findings suggest that renal tubular dysfunction might be more progressive in women than that in men.

A 30% incidence of renal cysts with varying sizes and densities in biomedical research swine is not associated with renal dysfunction

Background:Renal cystic disease arising from various etiologies results in fluid-filled cavities within the kidneys.Moreover,preexisting renal dysfunction has been shown to exacerbate multiple pathologies.While swine bred for biomedical research are often clinically inspected for illness/parasites,more advanced diagnostics may aid in uncovering underlying renal abnormalities.Methods:Computed tomography was performed in 54 female prepubertal Yorkshire swine to characterize renal cysts;urine and blood chemistry,and histology of cysts were also performed.Results:Digital reconstruction of right and left kidneys demonstrated that roughly one-third of the animals(17/54;31%)had one or more renal cyst.Circulating biomarkers of renal function were not different between animals that had cysts and those that did not.Alternatively,urinary glucose(P=.03)was higher and sodium(P=.07)tended to be lower in animals with cysts compared to animals without,with no differences in protein(P=.14)or potassium(P=.20).Aspiration of cystic fluid was feasible in two animals,which revealed that the cystic fluid urea nitrogen(97.6±28.7 vs 911.3±468.2 mg/dL),potassium(29.8±14.4 vs 148.2±24.85 mmol/L),uric acid(2.55±1.35 vs 11.4±5.65 mg/dL),and creatinine(60.34±17.26 vs 268.99±95.79 mg/dL)were much lower than in the urine.Histology demonstrated a cyst that markedly compresses the adjacent cortex and is lined by a single layer of flattened epithelium,bounded by fibrous connective tissue which extends into the parenchyma.There is tubular atrophy and loss in these areas.Conclusion:This study provides valuable insight for future studies focusing on kidney function in swine bred for biomedical research.

Impact of comorbid renal dysfunction in patients with hepatocellular carcinoma on long-term outcomes after curative resection

BACKGROUND Hepatocellular carcinoma(HCC)is one of the most common malignancies worldwide.However,the number of patients with chronic kidney disease(CKD)is on the rise because of the increase in lifestyle-related diseases.AIM To establish a tailored management strategy for HCC patients,we evaluated the impact of comorbid renal dysfunction(RD),as stratified by using the estimated glomerular filtration rate(EGFR),and assessed the oncologic validity of hepatectomy for HCC patients with RD.METHODS We enrolled 800 HCC patients who underwent hepatectomy between 1997 and 2015 at our university hospital.We categorized patients into two(RD,EGFR<60 mL/min/1.73 m^(2);non-RD,EGFR≥60 mL/min/1.73 m^(2))and three groups(severe CKD,EGFR<30 mL/min/1.73 m^(2);mild CKD,30≤EGFR<60 mL/min/1.73 m2;control,EGFR≥60 mL/min/1.73 m^(2))according to renal function as defined by the EGFR.Overall survival(OS)and recurrence-free survival(RFS)were compared among these groups with the log-rank test,and we also analyzed survival by using a propensity score matching(PSM)model to exclude the influence of patient characteristics.The mean postoperative observation period was 64.7±53.0 mo.RESULTS The RD patients were significantly older and had lower serum total bilirubin,aspartate aminotransferase,and aspartate aminotransferase levels than the non-RD patients(P<0.0001,P<0.001,P<0.05,and P<0.01,respectively).No patient received maintenance hemodialysis after surgery.Although the overall postoperative complication rates were similar between the RD and non-RD patients,the proportions of postoperative bleeding and surgical site infection were significantly higher in the RD patients(5.5%vs 1.8%;P<0.05,3.9%vs 1.8%;P<0.05,respectively),and postoperative bleeding was the highest in the severe CKD group(P<0.05).Regardless of the degree of comorbid RD,OS and RFS were comparable,even after PSM between the RD and non-RD groups to exclude the influence of patient characteristics,liver function,and other causes of death.CONCLUSION Comorbid mild RD had a negligible impact on the prognosis of HCC patients who underwent curative hepatectomy with appropriate perioperative management,and close attention to severe CKD is necessary to prevent postoperative bleeding and surgical site infection.

A Comparative Retrospective Analysis of Mortality, Renal Dysfunction, and Incidence of Bleeding in Patients Receiving Hydroxyethyl Starch 130/0.4 (HES 130/0.4) or Albumin

Background: In June 2013, the FDA issued a Black Box Warning on synthetic colloids resulting from data indicating an increased risk of mortality, renal injury, and excess bleeding incidence in septic patients admitted to the Intensive Care Unit (ICU), and patients undergoing coronary artery bypass graft (CABG) surgery. The purpose of this study was to compare the incidence of mortality, incidence/severity of renal injury and bleeding in septic ICU patients, and patients undergoing CABG surgery who have received hydroxyethyl starch 130/0.4 or albumin. Methods: This was a retrospective, single center, cohort study conducted at a 433 bed tertiary care hospital in Lexington, Kentucky. Computer generated lists provided patients who received hydroxyethyl starch 130/0.4 or albumin during inpatient stay as either a sepsis patient in the ICU or post coronary artery bypass graft patient. All cause mortality was the primary endpoint and secondary endpoints included overall renal dysfunction, incidence of bleeding, and overall length of stay. Results: A total of 89 patients were evaluated that received albumin or hydroxyethyl starch 130/0.4 alone with either septic ICU or CABG diagnosis codes. There was no significant difference in all cause mortality (p = 0.64). Overall renal dysfunction showed no statistically significance between the two groups (p = 0.66). There was no statistically significant difference between the albumin or HES 130/0.4 arms with respect to bleeding (TIMI Minimal p = 0.57, TIMI Minor p = 0.69, TIMI Major p = 0.35). Patient who received albumin had a statistically significant longer hospital overall length of stay (p = 0.003). Conclusion: There was no difference between HES 130/0.4 and albumin in mortality, renal dysfunction, and bleeding in septic ICU and CABG patients. Patients receiving albumin had an increased overall length of stay. These findings suggest that hydroxyethyl starch 130/0.4 may be safe in the studied patient populations;however, further investigation into specific HES agents should be conducted.

The investigation of the relationship between renal dysfunction and coronary heart disease

Objectives To evaluate the relationship of renal dysfunction,coronary heart disease and percutaneous coronary intervention(PCI).Methods(l)The subjects:There were 376 patients who come from department of cardiology of our hospital in this study undergoing coronary angiography.The patients were divided into two groups? according to coronary angiography:coronary artery disease(group A,n =263),in which 141 patients with renal dysfunction(group A1) and 122 patients with normal renal function(group A2):patients with other kinds of cardiovascular disease but normal coronary angiography(group B.n=113).Before the coronary angiography, all patients were measured the serum creatinine, microalbuminuria,fasting blood-glucose,triglycerides,total cholesterol,high density lipoprotein,low density lipoprotein, blood pressure in fasting 12 hours.(2)The diagnostic criteria for renal dysfunction:male serum creatinine】115 umol/L and/or microalbuminuria】30 mg,female】107 umol/L and/ or】30 mg.Results(1)The differences of renal function indexes in the group A and B:The mean level of microalbuminuria and serum creatinine was higher significantly in group A than that of the group B(43.48±38.93 vs.11.23±7.07 and 101.52±37.22 vs.80.62±17.4 respectively.Conclusions The coronary heart disease patients with renal dysfunction had more severe coronary artery stenosis,The renal dysfunction is a strong and independent risk factors for the coronary heart disease and beeds more revascularization therapy.

Serum cystatin C levels are negatively correlated with post-stroke cognitive dysfunction

Stroke is the leading cause of death and long-term disability worldwide,and cognitive impairment and dementia are major complications of ischemic stroke.Cystatin C (CysC) has been found to be a neuroprotective factor in animal studies.However,the relationship between CysC levels and cognitive dysfunction in previous studies has revealed different results.This prospective observational study investigated the correlation between serum CysC levels and post-stroke cognitive dysfunction at 3 months.Data from 638 patients were obtained from the China Antihypertensive Trial in Acute Ischemic Stroke (CATIS).Cognitive dysfunction was assessed using the Mini-Mental State Examination (MMSE) at 3 months after stroke.According to the MMSE score,308 patients (52.9%) had post-stroke cognitive dysfunction.After adjusting for potential confounding factors,the odds ratio (95% CI) of post-stroke cognitive dysfunction for the highest quartile of serum CysC levels was 0.54 (0.30–0.98),compared with the lowest quartile.The correlation between serum CysC and cognitive dysfunction was modified by renal function status.We observed a negative linear dose-response correlation between CysC and cognitive dysfunction in patients with normal renal function (Plinearity = 0.044),but not in those with abnormal renal function.Elevated serum CysC levels were correlated with a low risk of 3-month cognitive dysfunction in patients with acute ischemic stroke,especially in those with normal renal function.The current results suggest that CysC is a protective factor for post-stroke cognitive dysfunction,and could be used to treat post-stroke cognitive dysfunction.The CATIS study was approved by the Institutional Review Boards at Soochow University from China (approval No.2012-02) on December 30,2012,and was registered at ClinicalTrials.gov (identifier No.NCT01840072) on April 25,2013.

Lower urinary tract dysfunction in pediatrics progress to kidney disease in adolescents:Toward precision medicine in treatment

Newborn infants who had neurogenic bladder dysfunction(NBD)have a normal upper urinary tract at birth.Most of them will develop deterioration of renal function and chronic kidney disease if they do not receive proper management.Children with NBD can develop renal damage at adolescence or earlier,which is due to high detrusor pressures resulted from poor compliance of the bladder,detrusor overactivity against a closed sphincter or detrusor sphincter dyssynergia.To preserve renal function and prevent deterioration of the kidneys,NBD must be treated immediately after being diagnosed.Over the last few years there was great progress in the treatment of children with the NBD.We searched PubMed and the Cochrane Library for peer-reviewed articles published in any language up to March 10,2021,using the search term“neurogenic bladder children.”Our search excluded diagnosis,pathophysiology,surgical treatment of spinal cord injury and spina bifida.The research identified the effectiveness of treatment regimens targeting prevention of chronic kidney disease and the indications of kidney transplantation.The results of the research showed that NBD in children should be diagnosed early in life,and the child should receive the proper management.The literature search concluded that the management of NBD in children would be personalized for every case and could be changed according to response to treatment,side effects,child compliance,availability of treatment modality and costs of treatment.The objectives of the study are to present the different options of management of NBD in children and the selection of the proper method in a personalized manner.
