But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio.

Methods: Seventy-two newly diagnosed MM patients entered into our study and all the patients belonged to International Stage System (ISS) 3 in which transplantation patients were excluded or the patients refused receiving transplantation therapy. According to the level of serum creatinine (Scr), the patients were divided into two groups including group 1 (n=42) (Scr 〈2 mg/dL) and group 2 (n=30) (Scr ≥2 mg/dL). All the patients received the therapy of BTD regimen as induction therapy, and the median treatment time was 5 (range, 2-8) cycles. The outcome was analyzed retrospectively. Results: The overall remission (OR) rates were 81.0% (group 1) and 80.0% (group 2). There was no statistical difference between the two groups (P〉0.05). In group 2, 10 patients (33.3%) got renal function reversal, 14 patients (46.7%) got improved renal function and the median time to renal function reversal was 1.4 (range, 0.7-3.0) months. Among 12 patients with hemodialysis at diagnosis, 8 patients got rid of hemodialysis after median 4 cycles of therapy (range, 3-6 cycles). After a median follow-up period of 16 (range, 2-31) months, 5 patients (11.9%) in group 1 died and 9 patients (30.0%) in group 2 died (P=0.056). The 2-year estimate of overall survival was 77.3% in group 1 and 63.8% in group 2, respectively (P=0.188). During a median follow-up time of 13.0 months (range, 2-25 months), 15 patients (35.7%) in group 1 progressed and 13 patients (43.3%) in group 2 progressed (P=0.513). The 2-year estimate of response duration was 50.6% in group 1 and 42.1% in group 2, respectively (P=1). The main toxicities in the two groups included thrombocytopenia, peripheral neuropathy (PN), infection, herpes zoster and so on. The incidence of grade 3 and 4 adverse events was low. Conclusions: BTD regimen may become the front-line therapy for the newly diagnosed MM patients with renal impairment because BTD regimen can improve the prognosis of the patients with renal impairment as good as the patients without renal impairment.展开更多

Methods: Seventy-six EH patients were randomly assigned to the control group and the treated group, the former was given amlodipine, captopril/uropidil and the latter was given in addition Breviscapine intravenously dripped for 2 treatment courses. The indexes of serum creatinine (Cr), blood urea nitrogen (BUN), blood and urinary β 2-microglobulin (β 2-MG), and quantitative determination of 24 hrs urinary protein were evaluated before and after treatment. Results: In the control group, compared with before treatment, the quantitative determination of 24 hrs urinary protein got reduced significantly ( P <0.05), while in the treated group, both urinary β 2-MG and quantitative determination of 24 hrs urinary protein got lowered significantly ( P <0.05 and P <0.01). But after treatment, compared with the control group, urinary β 2-MG and quantitative determination of 24 hrs urinary protein in the treated group were obviously reduced ( P <0.05). Conclusion: Besides lowering blood pressure effectively, Breviscapine could improve the renal function significantly and reduce the urinary micro-albuminuria, hence showing promising effect on renal protection.展开更多

After preliminary grey-scale and color Doppler investigation, each kidney was investigated individually with CEUS, using 1.2-2.4 mL of a sulfur hexafluoride-filled microbubble contrast agent. Image analysis was performed in consensus by two readers who reviewed digital clips of CEUS. We calculated the detection rate of vascular abnormalities in the first group and performed descriptive statistics of imaging findings for the second group.RESULTSIn the first group, CEUS detected renal infarction or cortical ischemia in 18/50 patients (36%; 95%CI: 23.3-50.9) and 1/50 patients (2%; 95%CI: 0.1-12), respectively. The detection rate of infarction was significantly higher (P = 0.0002; McNemar test) compared to color Doppler ultrasonography (10%). No vascular causes of ARF were identified in the remaining 31/50 patients (62%). In the second group, CEUS detected 41 lesions on 39 patients, allowing differentiation between solid lesions (21/41; 51.2%) vs complex cysts (20/41; 48.8%), and properly addressing 15/39 patients to intervention when feasible based on clinical conditions (surgery and cryoablation in 13 and 2 cases, respectively). Cysts were categorized Bosniak II, IIF, III and IV in 8, 5, 4 and 3 cases, respectively. In the remaining two patients, CEUS found 1 pseudolesion and 1 subcapsular hematoma.CONCLUSIONCEUS showed high detection rate of renal perfusion abnormalities in patients with ARF, influencing the management of patients with acute or chronic RFI and renal masses throughout their proper characterization.展开更多

In this study, we aimed to optimize the dosage regimen of dalbavancin in patients with hepatic or renal impairment by Mote Carlo simulation. Pharmacokinetic parameters and microbiological data were collected about dalbavancin. 10,000 patients with renal or hepatic impairment analyzed by Crystal Ball to calculate probability of target attainment (PTA) and cumulative fraction of response (CFR). We found that all bacterial PTA and CFR were more than 90% for dalbavancin in patients with hepatic or renal impairment, except for Enterococcus faecium. There is no need to adjust the dosage regimen of dalbavancin in patients with hepatic or renal impairment.展开更多

An impression of the pulmonary renal syndrome was made and he was managed aggressively with haemodialysis, plasma exchange and pulsing with methyl prednisolone. His condition improved, but the renal functions did not. The vasculitic workup including Extractable Nuclear Antigen (ENA) and Anti-Neutrophil Cytoplasmic Antibody (ANCA) which were sent on admission came out to be negative. As he apparently responded to the initial management protocol, he was subjected to renal biopsy which did not reveal any vasculitis but was consistent for end-stage renal disease. Subsequently he was subjected to lung biopsy which also was not supportive for vasculitis. However, we concluded that the initial pointers for Wegener’s granulomatosis were misleading. The haemoptysis entirely subsided as the congestion improved. He was maintained on Haemodialysis three times per week schedule and discharged to the peripheral health care facility.展开更多

Methods: The 27 cases of multiple myeloma with the onset of renal impair-ment were collected in Department of Nephrology, Wuhan General Hospital of Guangzhou Command, China, from January 2007 to January 2011. All cases were divided into the groups with renal dysfunction (n = 16) and normal renal function (n = 11). The clinic manifestations, treatments and prognosis of all patients were analyzed. Results: Of all the patients in normal renal function group, 5 suffered nephrotic syndrome, 4 had abnormal results of routine urinalysis (hematuria or proteinuria) which were not caused by nephrotic syndrome, and 1 suffered urinary tract infection. Five pathological specimens of renal biopsy revealed that light chain protein, immunoglobulin and complement C3 were deposited mainly in the glomerular base-ment membrane and mesangia, tubular basement membrane and arteriolar walls. Two pathological specimens were proved to be renal amyloidosis. Patients with renal dysfunction had poorer prognosis, severer anemia, higher values of serum lactate dehydrogenase (LDH) and β2-microglobulin (β2-MG), worse responses to chemotherapy. Of 16 patients with renal dysfunc-tion, 14 (87.5%) were stage III, which were significantly higher than that in the group of normal renal function [63.6% (7/11)]. Of 16 cases with renal dysfunction, 9 were treated with blood purification, and 5 of 9 cases were treated with plasma exchange. Conclusion: Multiple myeloma with the onset of renal impairment was easily misdiagnosed. Hemodialysis concomitant with chemotherapy could contribute to recovery of renal function.展开更多

Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid (UA) metabolism. This study was to assess their potential relations to UA metabolism in heart failure. Methods We retrospectively assessed clinical charac- teristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure (n = 553). By clustering of indices, those variables were explored using factor analysis. Results In factor analysis, serum uric acid (SUA) formed part of a principal cluster of renal functional variables which included serum creatinine (SCr) and blood urea nitrogen (BUN). Univariate correlation coefficients between variables of patients with congestive heart failure showed that the strongest correlations for SUA were with BUN (r = 0.48, P 〈 0.001) and SCr (r = 0.47, P 〈 0.001). Conclusions There was an inverse relationship between SUA levels and measures of renal function in patients with congestive heart failure. The strong correlation between SUA and SCr and BUN levels suggests that elevated SUA concentrations reflect an impairment of renal function in heart failure.展开更多

When adequate magnesium supplementation is chronically given, patients with type 2 DM appear to have improved glucose control and may have delayed chronic complications. In addition, magnesium supplementation may slow the progression of chronic kidney disease (CKD) and decrease the risk of contrast-induced nephropathy in patients with type 2 DM. Keeping serum magnesium at 2.0 mEq/L or greater appears to accomplish these benefits for patients with type 2 DM. Periodically measuring serum magnesium and estimated glomerular filtration rate (eGFR) allows a physician to adjust the supplemental magnesium dose to accomplish these therapeutic goals while avoiding hypermagnesemia.展开更多

In addition, the renal function was evaluated in 5 adults receiving renal transplantations using cystatin C.Methods:Serum cystatin C levels were measured by a particle-enhanced nephelometric immunoassay on Dade Behring nephelometer system. Serum and urine creatinine concentrations were determined by use of Jaff’s kinetic assay.Results: The cystatin C concentration at birth was typically double that found in adults, then fell to a constant level after 1 year, a value that was maintained to about 60 years. The studies of cystatin C in the elderly showed that the circulation cystatin C levels rose gradually above 60 years. There was a significant positive correlation between serum cystatin C and creatinine level (r=0.921, P <0.01) in the patients with various renal diseases. Serum cystatin C was inversely and logarithmically correlated with creatinine clearance as shown in the equation lg cystatin C =-0.6061gCCr+1.209(r=-0.887, P <0.01). Serum cystatin C levels rose prior to creatinine concentrations and started to increase over normal range when creatinine clearance remained within normal range. After renal transplantation,cystatin C concentration significantly decreased during the first week(-43% vs -21% for creatinine) in patients without delayed graft function. In some cases of acute renal impairment, the increase in serum cystatin C values was more prominent than that of creatinine.Conclusion:Serum cystatin C is probably more attractive for estimation of renal function than serum creatinine and creatinine clearance especially for detection of the mild reduction of glomerular filtrate rate in patients with various kidney diseases. Serum cystatin C can also be used as an alternative marker of allograft function in adult transplant patients.展开更多

文摘Background:Nonalcoholic fatty liver disease(NAFLD)is associated with impaired renal function,and both diseases often occur alongside other metabolic disorders.However,the prevalence and risk factors for impaired renal function in patients with NAFLD remain unclear.The objective of this study was to identify the prevalence and risk factors for renal impairment in NAFLD patients.Methods:All adults aged 18-70 years with ultrasound-diagnosed NAFLD and transient elastography examination from eight Asian centers were enrolled in this prospective study.Liver fibrosis and cirrhosis were assessed by FibroScan-aspartate aminotransferase(FAST),Agile 3+and Agile 4 scores.Impaired renal function and chronic kidney disease(CKD)were defined by an estimated glomerular filtration rate(eGFR)with value of<90 mL/min/1.73 m^(2) and<60 mL/min/1.73 m^(2),respectively,as estimated by the CKD-Epidemiology Collaboration(CKD-EPI)equation.Results:Among 529 included NAFLD patients,the prevalence rates of impaired renal function and CKD were 37.4%and 4.9%,respectively.In multivariate analysis,a moderate-high risk of advanced liver fibrosis and cirrhosis according to Agile 3+and Agile 4 scores were independent risk factors for CKD(P<0.05).Furthermore,increased fasting plasma glucose(FPG)and blood pressure were significantly associated with impaired renal function after controlling for the other components of metabolic syndrome(P<0.05).Compared with patients with normoglycemia,those with prediabetes[FPG≥5.6 mmol/L or hemoglobin A1c(HbA1c)≥5.7%]were more likely to have impaired renal function(P<0.05).Conclusions:Agile 3+and Agile 4 are reliable for identifying NAFLD patients with high risk of CKD.Early glycemic control in the prediabetic stage might have a potential renoprotective role in these patients.
文摘Diabetes mellitus(DM)is defined as a chronic disease of disordered metabolism with an ongoing increase in prevalence and incidence rates.Renal disease in patients with diabetes is associated with increased morbidity and premature mortality,particularly attributed to their very high cardiovascular risk.Since this group of patients frequently lacks specific symptomatology prior to the adverse events,a screening tool for the identification of high-risk patients is necessary.The epicardial adipose tissue(EAT)is a biologically active organ having properties similar to visceral adipose tissue and has been associated with metabolic diseases and coronary artery disease.Superior to conventional cardiovascular risk factors and anthropometric measures,including body mass index and waist circumference,the EAT can early predict the development of coronary artery disease.Assessment of EAT can be performed by twodimensional echocardiography,magnetic resonance imaging or computer tomography.However,its role and significance in patients with DM and nephropathy has not been thoroughly evaluated.The aim of the current editorial is to evaluate all available evidence regarding EAT in patients with DM and renal impairment.Systematic search of the literature revealed that patients with DM and nephropathy have increased EAT measurements,uncontrolled underlying disease,high body mass index and raised cardiovascular risk markers.Acknowledging the practical implications of this test,EAT assessment could serve as a novel and non-invasive biomarker to identify high-risk patients for cardiovascular adverse events.
文摘Dalbavancin is a novel semi-synthetic glycopeptide antibiotic. In this study, we aimed to optimize the dosage regimen of dalbavancin in patients with hepatic or renal impairment by Mote Carlo simulation. Pharmacokinetic parameters and microbiological data were collected about dalbavancin. 10,000 patients with renal or hepatic impairment analyzed by Crystal Ball to calculate probability of target attainment (PTA) and cumulative fraction of response (CFR). We found that all bacterial PTA and CFR were more than 90% for dalbavancin in patients with hepatic or renal impairment, except for Enterococcus faecium. There is no need to adjust the dosage regimen of dalbavancin in patients with hepatic or renal impairment.
文摘We received a 23-year-old male, working in the Army for 18 months, with advanced renal impairment, haemoptysis and hyperkalemia. An impression of the pulmonary renal syndrome was made and he was managed aggressively with haemodialysis, plasma exchange and pulsing with methyl prednisolone. His condition improved, but the renal functions did not. The vasculitic workup including Extractable Nuclear Antigen (ENA) and Anti-Neutrophil Cytoplasmic Antibody (ANCA) which were sent on admission came out to be negative. As he apparently responded to the initial management protocol, he was subjected to renal biopsy which did not reveal any vasculitis but was consistent for end-stage renal disease. Subsequently he was subjected to lung biopsy which also was not supportive for vasculitis. However, we concluded that the initial pointers for Wegener’s granulomatosis were misleading. The haemoptysis entirely subsided as the congestion improved. He was maintained on Haemodialysis three times per week schedule and discharged to the peripheral health care facility.

文摘The structure and function of brain networks have been altered in patients with end-stage renal disease(ESRD).Manifold regularization(MR)only considers the pairing relationship between two brain regions and cannot represent functional interactions or higher-order relationships between multiple brain regions.To solve this issue,we developed a method to construct a dynamic brain functional network(DBFN)based on dynamic hypergraph MR(DHMR)and applied it to the classification of ESRD associated with mild cognitive impairment(ESRDaMCI).The construction of DBFN with Pearson’s correlation(PC)was transformed into an optimization model.Node convolution and hyperedge convolution superposition were adopted to dynamically modify the hypergraph structure,and then got the dynamic hypergraph to form the manifold regular terms of the dynamic hypergraph.The DHMR and L_(1) norm regularization were introduced into the PC-based optimization model to obtain the final DHMR-based DBFN(DDBFN).Experiment results demonstrated the validity of the DDBFN method by comparing the classification results with several related brain functional network construction methods.Our work not only improves better classification performance but also reveals the discriminative regions of ESRDaMCI,providing a reference for clinical research and auxiliary diagnosis of concomitant cognitive impairments.
文摘Objective: The aim of the study was to investigate the clinic manifestation, diagnosis and treatment on multiple myeloma (MM) with the onset of renal impairment. Methods: The 27 cases of multiple myeloma with the onset of renal impair-ment were collected in Department of Nephrology, Wuhan General Hospital of Guangzhou Command, China, from January 2007 to January 2011. All cases were divided into the groups with renal dysfunction (n = 16) and normal renal function (n = 11). The clinic manifestations, treatments and prognosis of all patients were analyzed. Results: Of all the patients in normal renal function group, 5 suffered nephrotic syndrome, 4 had abnormal results of routine urinalysis (hematuria or proteinuria) which were not caused by nephrotic syndrome, and 1 suffered urinary tract infection. Five pathological specimens of renal biopsy revealed that light chain protein, immunoglobulin and complement C3 were deposited mainly in the glomerular base-ment membrane and mesangia, tubular basement membrane and arteriolar walls. Two pathological specimens were proved to be renal amyloidosis. Patients with renal dysfunction had poorer prognosis, severer anemia, higher values of serum lactate dehydrogenase (LDH) and β2-microglobulin (β2-MG), worse responses to chemotherapy. Of 16 patients with renal dysfunc-tion, 14 (87.5%) were stage III, which were significantly higher than that in the group of normal renal function [63.6% (7/11)]. Of 16 cases with renal dysfunction, 9 were treated with blood purification, and 5 of 9 cases were treated with plasma exchange. Conclusion: Multiple myeloma with the onset of renal impairment was easily misdiagnosed. Hemodialysis concomitant with chemotherapy could contribute to recovery of renal function.

文摘BACKGROUND Townes–Brocks syndrome(TBS)is a rare autosomal dominant syndrome that is characterized by a triad of imperforate anus,dysplastic ears,and thumb malformations.Heterozygous variants of SALL1 are responsible for this syndrome.Renal structural abnormalities and functional impairments are often reported in TBS patients.CASE SUMMARY We report a case of TBS in a Chinese family.The index patients showed obvious renal atrophy and renal failure.TBS was suggested after a physical examination and pedigree analysis.Whole exome sequencing revealed a heterozygous variant of SALL1.The variant(NM_001127892 c.1289_c.1290 insC)led to a read-frame shift of the encoded protein,which was confirmed by Sanger sequencing.The variant cosegregated with the phenotype among affected members.CONCLUSION A novel variant in SALL1 gene may be the molecular pathogenic basis of this disorder.
文摘Background Hyperuricemia is frequently present in patients with heart failure. Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid (UA) metabolism. This study was to assess their potential relations to UA metabolism in heart failure. Methods We retrospectively assessed clinical charac- teristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure (n = 553). By clustering of indices, those variables were explored using factor analysis. Results In factor analysis, serum uric acid (SUA) formed part of a principal cluster of renal functional variables which included serum creatinine (SCr) and blood urea nitrogen (BUN). Univariate correlation coefficients between variables of patients with congestive heart failure showed that the strongest correlations for SUA were with BUN (r = 0.48, P 〈 0.001) and SCr (r = 0.47, P 〈 0.001). Conclusions There was an inverse relationship between SUA levels and measures of renal function in patients with congestive heart failure. The strong correlation between SUA and SCr and BUN levels suggests that elevated SUA concentrations reflect an impairment of renal function in heart failure.

文摘Anti-B cell maturation antigen(BCMA)chimeric antigen receptor(CAR)T-cell therapyis effective and well-tolerated for refractory or relapsed multiple myeloma(RRMM).The purposcof the present study was to analyze efficacy in RRMM patients with renal impairment treated byanti-BCMA CAR-T cell therapy.A total of 59 RRMM patients were selected,and divided intoimpaired renal function(lRF)group[basclinc cstimated giomerular filtration rate(eSFR)<90 m/min/1.73 m^2(n=18)]and normal renal function(NRF)group(baseline eGFR≥90 mL/min/1.73 m,n=41).For patients with IRF,eGFR at the 6th month post-CAR-T cells infusion was significantlyhigher than the baseline(P<0.05).The multivariate analysis showed that light chain type and beta-2 micro-globulin(bcta-2M)were associated factors with the decrease of serum creatinine.Medianprogression-free survival(PFS)in the NRF group and IRF group was 266 days and 181 daysrespectively.Overall survival(OS)in the NRF group and lRF group was 877 days and 238 daysrespectively.There was no significant difference in the objective response rate(ORR)between thelRF group and the NRF group.It is suggested that CAR-T cells therapy could improve the renalfunction during the treatment of RRMM.The renal function could be more significantly improvedin RRMM patients with light chain type than with other types.
文摘Glucagon-like peptide-1(GLP-1)receptor agonists result in greater improvements in glycemic control than placebo and promote weight loss with minimal hypoglycemia in patients with type 2 diabetes mellitus.A number of case reports show an association of GLP-1receptor agonists,mainly exenatide,with the development of acute kidney injury.The present review aims to present the available data regarding the effects of GLP-1 receptor agonists on renal function,their use in subjects with chronic renal failure and their possible association with acute kidney injury.Based on the current evidence,exenatide is eliminated by renal mechanisms and should not be given in patients with severe renal impairment or end stage renal disease.Liraglutide is not eliminated by renal or hepatic mechanisms,but it should be used with caution since there are only limited data in patients with renal or hepatic impairment.There is evidence from animal studies that GLP-1 receptor agonists exert protective role in diabetic nephropathy with mechanisms that seem to be independent of their glucose-lowering effect.Additionally,there is evidence that GLP-1 receptor agonists influence water and electrolyte balance.These effects may represent new ways to improve or even prevent diabetic nephropathy.

文摘Diabetes mellitus(DM) is a chronic metabolic disorder characterized by a combination of hyperglycemia, reduced insulin sensitivity, and/or relative impairment of insulin secretion[1]. Renal damage, which is a major microvascular complication of DM and a progressive kidney disease, has been considered the most common cause of end-stage renal disease[2]. Renal fibrosis is a common outcome of progressive renal damage.
文摘Magnesium deficiency is common in patients with type 2 diabetes mellitus (type 2 DM). When adequate magnesium supplementation is chronically given, patients with type 2 DM appear to have improved glucose control and may have delayed chronic complications. In addition, magnesium supplementation may slow the progression of chronic kidney disease (CKD) and decrease the risk of contrast-induced nephropathy in patients with type 2 DM. Keeping serum magnesium at 2.0 mEq/L or greater appears to accomplish these benefits for patients with type 2 DM. Periodically measuring serum magnesium and estimated glomerular filtration rate (eGFR) allows a physician to adjust the supplemental magnesium dose to accomplish these therapeutic goals while avoiding hypermagnesemia.
文摘Objective:To investigate the clinical usefulness in terms of estimation for glomerular filtration rate(GFR), we determined the serum cystatin C levels in 72 healthy adults , 63 children, and 109 patients with various renal diseases, and compared the serum cystatin C concentrations with serum creatinine levels. In addition, the renal function was evaluated in 5 adults receiving renal transplantations using cystatin C.Methods:Serum cystatin C levels were measured by a particle-enhanced nephelometric immunoassay on Dade Behring nephelometer system. Serum and urine creatinine concentrations were determined by use of Jaff’s kinetic assay.Results: The cystatin C concentration at birth was typically double that found in adults, then fell to a constant level after 1 year, a value that was maintained to about 60 years. The studies of cystatin C in the elderly showed that the circulation cystatin C levels rose gradually above 60 years. There was a significant positive correlation between serum cystatin C and creatinine level (r=0.921, P <0.01) in the patients with various renal diseases. Serum cystatin C was inversely and logarithmically correlated with creatinine clearance as shown in the equation lg cystatin C =-0.6061gCCr+1.209(r=-0.887, P <0.01). Serum cystatin C levels rose prior to creatinine concentrations and started to increase over normal range when creatinine clearance remained within normal range. After renal transplantation,cystatin C concentration significantly decreased during the first week(-43% vs -21% for creatinine) in patients without delayed graft function. In some cases of acute renal impairment, the increase in serum cystatin C values was more prominent than that of creatinine.Conclusion:Serum cystatin C is probably more attractive for estimation of renal function than serum creatinine and creatinine clearance especially for detection of the mild reduction of glomerular filtrate rate in patients with various kidney diseases. Serum cystatin C can also be used as an alternative marker of allograft function in adult transplant patients.
