Dinghao Zhuo, Xiang Li, Feng Guan
Glycosphingolipids (GSLs), which consist of a hydrophobic ceramide backbone and a hydrophilic carbohydrate residue, are an important type of glycolipid expressed in surface membranes of all animal cells. GSLs play essential roles in maintenance of plasma membrane stability, in regulation of numerous cellular processes (including adhesion, proliferation, apoptosis, and recognition), and in modulation of signal transduction pathways. GSLs have traditionally been classified as ganglio-series, lacto-series, or globo-series on the basis of their diverse types of oligosaccharide chains...

BACKGROUND: The importance of a serum creatinine increase, traditionally considered worsening renal function (WRF), during admission for acute heart failure has been recently debated, with data suggesting an interaction between congestion and creatinine changes. METHODS AND RESULTS: In post hoc analyses, we analyzed the association of WRF with length of hospital stay, 30-day death or cardiovascular/renal readmission and 90-day mortality in the PROTECT study (Placebo-Controlled Randomized Study of the Selective A1 Adenosine Receptor Antagonist Rolofylline for Patients Hospitalized With Acute Decompensated Heart Failure and Volume Overload to Assess Treatment Effect on Congestion and Renal Function)...

Chronic kidney disease is characterized by prolonged decline in renal function, excessive accumulation of ECM, and progressive tissue fibrosis. Transglutaminase (TG) is a crosslinking enzyme that catalyzes the formation of covalent bonds between glutamine and lysine residues, and is involved in the induction of renal fibrosis via the stabilization of ECM and the activation of TGF-β1. Despite the accumulating evidences indicating that TG2 is a key enzyme in fibrosis, genetic knockout of TG2 reduced by only 50% the elevated protein crosslinking and fibrous protein in renal fibrosis model, whereas treatment with TG inhibitor almost completely reduced these levels...

BACKGROUND: Diabetes is among the strongest predictors of outcome after coronary artery stenting and the incidence of negative outcomes is still high in this specific group. Data of long-term outcomes comparing diabetic patients with non-diabetic patients treated with bioresorbable scaffolds are still incomplete. This work evaluates the long-term outcomes after implantation of a coronary bioresorbable scaffold (BRS) in diabetic patients compared to non-diabetics. METHODS: Patients who received at least one Absorb BRS in the time of May 2012 to December 2014 were enrolled into this single-center registry...

While many patients have substantial residual kidney function (RKF) when initiating hemodialysis (HD), most patients with end stage renal disease in the United States are initiated on 3-times per week conventional HD regimen, with little regard to RKF or patient preference. RKF is associated with many benefits including survival, volume control, solute clearance, and reduced inflammation. Several strategies have been recommended to preserve RKF after HD initiation, including an incremental approach to HD initiation...

INTRODUCTION: Various innovations for preventing complications and improving a patient's quality of life have been implemented for peritoneal dialysis (PD), which was established in Japan approximately 35 years ago and introduced at our hospital in 1999. Herein, we investigate the outcomes of patients undergoing PD to identify approaches for improving their long-term prognosis. METHODS: This retrospective study included 114 patients who underwent PD between September 1999 and August 2017 and included various parameters such as patient survival rate, technical survival rate, cause (s) of PD withdrawal, incidence of peritonitis, dialysis duration, and change in residual renal function (RRF)...

In recent years, metabolomics using high-performance liquid chromatography (UPLC) has been used to study the metabolic profiles in plasma, urine, stool and tissue in animal model of chronic kidney disease (CKD). In the previous work, we found that traditional Chinese medicine (TCM) "Kidney Flaccidity Compound" (KFC) based on "kidney flaccidity theory" can improve renal function and quality of life of patients with kidney disease. This study aimed to investigate the metabolic profiles in peripheral blood of hemodialysis patients administrated by KFC for 1...

Objective: To investigate the clinical effect of "3+1" bladder function restoration combined with holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH) with acontractile detrusor (ACD). METHODS: We treated 35 BPH patients with ACD by HoLEP followed by "3+1" bladder function restoration, that is, a 3-phase bladder function training plus simultaneous 1-drug medication after surgery. We recorded and analyzed the detrusor pressure, post-void residual urine volume (PVR), maximum urinary flow rate (Qmax), International Prognostic Scoring System (IPSS) scores, quality of life (QoL), voluntary micturition, satisfaction with the bladder function, hydronephrosis, ureterectasia, renal function, and urinary tract infection of the patients before and after treatment...

Species differences in renal drug transporters continue to plague drug development with animal models failing to adequately predict renal drug toxicity. For example, adefovir, a renally excreted antiviral drug, failed clinical studies for HIV due to pronounced nephrontoxicity in humans. In this study, we demonstrated that there are large species differences in the kinetics of interactions of a key class of antiviral drugs, acyclic nucleoside phosphonates (ANPs), with OAT1 (SLC22A6) and identified a key amino acid residue responsible for these differences...

Background/aim: Blood pressure (BP) variability is more closely associated with adverse outcomes than ‘usual’ BP in the general population. Residual renal function (RRF) and left ventricular hypertrophy (LVH) are thought to be predictors of poor outcome in dialysis patients. However, only a few studies have focused on BP variation and its link to RRF, LVH, and outcome in peritoneal dialysis (PD) patients. Therefore, we aimed to explore the effect of visit-to-visit BP variability on RRF and LVH in continuous ambulatory PD (CAPD) patients...

BACKGROUND AND AIMS: There is increasing awareness that the intestinal microbiome plays an important role in human health. We investigated its role in the burden of carotid atherosclerosis, measured by ultrasound as total plaque area. METHODS: Multiple regression with traditional risk factors was used to identify three phenotypes among 316/3056 patients attending vascular prevention clinics. Residual score (RES; i.e. the distance off the regression line, similar to standard deviation) was used to identify the 5% of patients with much less plaque than predicted by their risk factors (Protected, RES <-2), the 90% with about as much plaque as predicted (Explained, RES -2 to 2), and the 5% with much more plaque than predicted (Unexplained RES >2)...

Direct oral anticoagulants (DOAC) possess high bioavailability, and their anticoagulant effect is more predictable than that of vitamin K antagonists, hence they do not require routine dose adjustment based on laboratory testing. However, there are circumstances when laboratory testing may be useful, including patients who need to undergo surgery or invasive procedures. Most guidelines state that patients on DOAC may safely undergo surgery/invasive procedures by stopping anticoagulation for a few days before intervention without testing if renal function is within normal limits...

Background: Both dialysis dose and residual kidney function (RKF) contribute to solute clearance and are associated with outcomes in hemodialysis patients. We hypothesized that the association between dialysis dose and mortality is attenuated with greater RKF. Methods: Among 32 251 incident hemodialysis patients in a large US dialysis organization (2007-11), we examined the interaction between single-pool Kt/V (spKt/V) and renal urea clearance (rCLurea) levels in survival analyses using multivariable Cox proportional hazards regression model...

Cryptophthalmos (CO, MIM: 123570) is rare congenital anomalies of eyelid formation, which can occur alone or in combination with multiple congenital anomalies as part of Fraser syndrome (FS) or Manitoba Oculotrichoanal (MOTA) syndrome. Causal mutations have been identified for these syndromes but not in the isolated cases. Here, we described two patients from two unrelated Chinese families: one with unilateral isolated CO, while the other with unilateral CO and renal agenesis. A novel homozygous mutation (c...

BACKGROUND: In end-stage renal disease patients treated with peritoneal dialysis (PD), the osmotic conductance to glucose (OCG) represents the intrinsic ability of the membrane to transport water in response to a crystalloid osmotic gradient. A progressive loss of OCG in long-term PD patients indicates the development of fibrosis in the peritoneal interstitium, and helps identify patients at risk for encapsulating peritoneal sclerosis. The double mini-peritoneal equilibration test (PET) has been proposed as a simple method to assess OCG using the difference in initial ultrafiltration rates generated by 2 successive dwells using 1...

Patients with diabetic nephropathy develop nephrotic syndrome, and may show limited response to conventional therapy. They often require earlier initiation of renal replacement therapy because they become refractory to diuretics, and experience excessive fluid retention. We aimed to investigate the efficacy of tolvaptan, an oral arginine vasopressin type 2 receptor antagonist, in a case series of 14 severe diabetic renal failure patients who were severely refractory to maximal doses of furosemide and had excessive fluid retention despite preserved cardiac function and residual renal function...

The share of peritoneal dialysis (PD) in the spectrum of chronic dialysis has decreased in France over the last ten years. Despite various facilities offered by the health authorities, PD remains confidential in many private units and some public hospitals. The enthusiasm present at the beginning of this technology, forty years ago, is declining, despite a real improvement in new developments, a real increase in patient survival, today at least similar to that on hemodialysis. Then, the aim of this review is first to give a summary of the principles and practice of patient and staff education and to describe the role of the medical contribution in decision-making...

The majority of incidental haemodialysis patients are systematically treated at the rate of three sessions per week, regardless of their level of residual kidney function. Incremental haemodialysis is a therapeutic strategy adapted to the residual kidney function level of each patient, to offer patients only the "dialysis dose" needed to supplement their residual kidney function, while ensuring that they achieve the objective of total clearance (renal+per-HD) recommended (weekly Standard Kt/V urea>2...
