AIMS: To characterize the incidence of diabetes-associated complications and assess the safety of sitagliptin in participants with chronic kidney disease (CKD) in the Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS). MATERIALS AND METHODS: For participants with baseline eGFR measurements (n = 14,528), baseline characteristics and safety outcomes were compared for the CKD cohort (eGFR <60 mL/min per 1.73 m(2) ) versus those without CKD. Within the CKD cohort, the same analyses were performed comparing sitagliptin- and placebo-assigned participants...

AIMS: Variability in HbA1c and blood pressure (BP) is associated with the risk of diabetic kidney disease (DKD). No evidence exists on the role of variability in lipids or serum uric acid (UA), or the interplay between the variability of different parameters, on renal outcomes. MATERIALS AND METHODS: Within the AMD Annals database we identified patients with ≥5 measurements of HbA1c, SBP and DBP, total-, HDL- and LDL- cholesterol, triglycerides, and UA. Patients were followed-up for up to 5 years...

AIM: Tenapanor (RDX5791/AZD1722), an inhibitor of gastrointestinal Na(+) /H(+) exchanger NHE3, is being evaluated for the treatment of patients with constipation-predominant irritable bowel syndrome and the treatment of hyperphosphataemia in patients with chronic kidney disease on dialysis. By reducing intestinal H(+) secretion, inhibition of NHE3 by tenapanor could indirectly affect H(+) -coupled transporter activity, leading to drug-drug interactions. We investigated the effect of tenapanor on the activity of the H(+) -coupled peptide transporter PepT1 via assessment of the pharmacokinetics of cefadroxil - a compound transported by PepT1 - in healthy volunteers...

REVIEW
Saurabh Rajpal, Laith Alshawabkeh, Alexander R Opotowsky
PURPOSE OF REVIEW: There is an increasing number of adult patients with congenital heart disease (CHD). While several biomarkers have been validated and integrated into general cardiology clinical practice, these tests are often applied to adults with CHD in the absence of disease-specific validation. Although these patients are often grouped into a single population, there is heterogeneous pathophysiology, variable disease chronicity, extensive multisystem involvement, and a low event rate relative to acquired heart disease...

Osteoporosis and chronic kidney disease (CKD) have both independently important potential impact on bone health. A significant number of patients with CKD stages 3a-5D have been shown to have low bone mineral density (BMD), leading to a strikingly elevated risk of fractures (mainly hip fractures) and higher associated morbidity and mortality. Mechanical properties of bone beyond age and menopausal status are additionally affected by intrinsic uremic factors. Therefore, we review in this article not only general concepts of osteoporosis and related consequences, but also the diagnostic and therapeutic implications of low BMD and bone fractures in CKD, beyond increased vascular calcification...

REVIEW
Matthew R Allen, Mohammad W Aref
PURPOSE OF REVIEW: Bisphosphonates (BPs) have long been the gold-standard anti-remodeling treatment for numerous metabolic bone diseases. Since these drugs are excreted unmetabolized through the kidney, they are not recommended for individuals with compromised kidney function due to concerns of kidney and bone toxicity. The goal of this paper is to summarize the preclinical BP work in models of kidney disease with particular focus on the bone, kidney, and vasculature. RECENT FINDINGS: Summative data exists showing positive effects on bone and vascular calcifications with minimal evidence for bone or kidney toxicity in animal models...

Diabetes duration, diabetic retinopathy (DR), and a diagnostic model have been proposed as clinical parameters favoring the presence of diabetic nephropathy (DN) in biopsied patients with diabetic kidney disease. DN, compared with non-diabetic renal disease, had poorer renal outcomes. We tested whether these clinical parameters favoring DN are associated with poorer renal outcomes in non-biopsied patients. In this study, 1330 patients with type 2 diabetes and chronic kidney disease stages 1-4 were included and divided according to diabetes mellitus (DM) duration >8 years, DR, or a diagnostic model for DN...

MG53 (also known as TRIM72) is a cardiac and skeletal muscle-specific TRIM-family protein that exhibits multiple biological functions. First, MG53 participates in plasma membrane repair of the heart, skeletal muscle and other tissues. Second, MG53 is essentially involved in the cardioprotection of cardiac ischemic, pre-conditioning and post-conditioning, by activating the PI3K-Akt-GSK3β and ERK1/2 survival signaling pathways. Moreover, systemic delivery of recombinant MG53 protein ameliorates the impact of a range of injury insults on heart, skeletal muscle, lung, kidney, skin and brain...

BACKGROUND: Angioplasty on the radial artery have been performed with good success rates in patients with critical hand ischemia. We sought to assess the feasibility and safety of radial angioplasty on complex radial access in patients undergoing coronary angiography. METHODS/MATERIAL: A prospective series of procedures with complex radial/ulnar access to which radial-ulnar angioplasty (RU-A) was performed. We set goals of efficacy and safety that included the success rate of the procedure (need for ¨Crossover femoral¨) and the existence of radial pulse at one month...

BACKGROUND: Calciphylaxis is a serious complication in patients with chronic kidney disease associated mineral and bone disorder. It can occur in conditions with low and high bone turnover. So far, there are no definite diagnostic and therapeutic guidelines which may prevent the devastating outcome in many calciphylaxis patients. We report a case which clearly illustrates that knowledge of the underlying bone disorder is essential for a directed treatment. Based on this experience we discuss a systematic diagnostic and therapeutic approach in patients with calciphylaxis...

Background: Chronic kidney disease (CKD) is a risk factor for adverse drug events. The clinical significance of discordance between renal prescribing references is unknown. Aim: We determined the prevalence of potentially inappropriate prescribing (PIP) in CKD, measured agreement between two prescribing references, and assessed potential for harm consequent to PIP. Design: Single-centre observational study. Methods: A random sample of hospitalised patients with CKD were grouped according to baseline CKD stage (3, 4, or 5)...

Although cardiovascular disease is a major health burden for patients with chronic kidney disease, most cardiovascular outcome trials have excluded patients with advanced chronic kidney disease. Moreover, the major cardiovascular outcome trials that have been conducted in patients with end-stage renal disease have not demonstrated a treatment benefit. Thus, clinicians have limited evidence to guide the management of cardiovascular disease in patients with chronic kidney disease, particularly those on dialysis...

Kidney allograft failure due to chronic injury/rejection remains the main cause of graft loss in renal transplant recipients (RTR). Here, we investigated whether specific biomarkers of extracellular matrix (ECM) turnover are associated with allograft function and chronic kidney disease (CKD) stage in RTR. Seventy-eight patients who attended the University Medical Center Groningen for a routine check-up after kidney transplantation were enrolled in the study. Plasma and/or 24h-urine samples were collected and specific matrix-metalloproteinase-generated neo-epitope fragments of collagens were measured by enzyme-linked immunosorbent assay...

BACKGROUND: Transurethral intracorporeal lithotripsy is the modality of choice for the endoscopic disintegration of large, long-standing, radiolucent or high-density stones. Despite several advantages and proven benefits of contact ureterolithotripsy/ureterolithoextraction (CULT), the application of irrigation carries significant risks of untoward perioperative events including retrograde stone migration and postoperative pyelonephritis. METHODS: We describe a new technique - endoscopic intracorporeal lithotripsy in the gas (СО2) medium...

The current management of Chronic Kidney Disease-Mineral Bone Disorder (CKD-MBD) relies largely on clinical judgement and assessment of biochemical parameters including serum calcium, phosphate and intact parathyroid hormone concentrations. In the past two decades, there has been a leap in the understanding of the pathophysiology of CKD-MBD, leading to the discovery of novel biomarkers. The potential utility of these markers in this clinical setting is an area of intense investigation. In the absence of any guidelines aiding the clinician's understanding and application of these markers, we summarise the current available literature surrounding fibroblast growth factor-23, α-Klotho, sclerostin and serum calcification propensity testing and their respective assays in the context of CKD-MBD management...
