Background: Periampullary neoplasms include carcinomas of the duodenum, ampulla of Vater, distal common bile duct, and pancreas. The aggressive course of these neoplasms is attributable to the delay in diagnosis, as patients have no symptoms until advanced stages of the disease. More than half of patients have distant metastasis at the time of diagnosis. The most frequent sites of metastasis are the liver, lymph nodes, peritoneum, lung, bone, kidney, and, rarely the skin. Case Report: We report the case of a 45-year-old female patient with adenocarcinoma of the ampulla of Vater metastasizing to the right parietal skull with overlying cutaneous involvement 1 year after a Whipple procedure...

BACKGROUND: The clinical consequences of starting chronic peritoneal dialysis (PD) after emergent dialysis via a temporary hemodialysis (HD) catheter has rarely been evaluated within a full spectrum of treated end-stage renal disease (ESRD). We investigated the longer-term outcomes of patients undergoing emergent-start PD in comparison with that of other practices of PD or HD in a prospective cohort of new-onset ESRD. METHODS: This was a 2-year prospective observational study...

AIM: Methylenetetrahydrofolate reductase (MTHFR) is a regulatory enzyme of homocysteine metabolism. The C677T and A1298C polymorphism of the MTHFR gene has been reported to be associated with elevated plasma homocysteine in patients with Diabetic nephropathy. This study aimed to investigate the influence of the C677T and A1298C polymorphisms on the progression chronic kidney disease in diabetic nephropathy of south Indian population. METHODS: We genotyped 145 DN cases and 100 controls for the C677T and A1298C polymorphisms using PCR-RFLP based protocols, and all diabetic nephropathy cases divided into two groups based on CKD stages: 60 DN cases were early stage (CKD1 to CKD3) and 85 DN cases were advanced stage (CKD4 and CKD5)...

BACKGROUND: Chronic kidney disease (CKD) is a condition that involves 10% - 15% of population worldwide, which increases the risk of cardio-vascular diseases (CVD). Chronic kidney disease is one of the main reasons for illness and mortality in the world. Chronic kidney disease is a serious health problem caused by involvement of a large number of patients with kidney injury, especially in industrial countries. Among the main reasons for this are population living longer and the number of diseases in elderly persons, such as diabetes mellitus type 2, hypertension, and cardio-vascular diseases...

Hydrogen sulfide (H2S) is synthesized in nearly all organ systems including the kidney. Recent findings have revealed that H2S functions as a gasotransmitter affecting a wide range of physiologic functions similar to other gasotransmitters nitric oxide (NO) and carbon monoxide (CO). Research on H2S regulation of kidney function is still in early stages. H2S increases glomerular filtration rate (GFR) and inhibits sodium absorption by the tubules. There is burgeoning evidence that H2S generation by kidney cells is reduced in acute and chronic disease states and that H2S donors ameliorate injury...

We report a case of a patient who had the mitochondrial cytopathy complex of neuropathy, ataxia, and retinitis pigmentosa (NARP) syndrome diagnosed at age 11 years with a biopsy-proven kidney involvement that progressed to end-stage renal disease at age 21 years. Mutations of mitochondrial DNA (mtDNA) are maternally inherited and lead to mitochondrial cytopathies with predominant neurologic manifestations: psychomotor retardation, epilepsy, ataxia, neuropathy, and myopathy. Given the ubiquitous nature of mitochondria, cellular dysfunction can also appear in tissues with high metabolic turnover; thus, there can be cardiac, digestive, ophthalmologic, and kidney complications...

Delayed bowel erosion by peritoneal dialysis catheter is rare with fewer than thirty cases having been reported in the literature. This complication is usually encountered when the catheter is kept dormant. Two cases have also been reported with catheters in active use. The risk factors for bowel erosion include immunosuppression, diverticulosis, and amyloidosis. An 80-year-old male with chronic kidney disease Stage 5 due to hypertensive nephrosclerosis underwent chronic ambulatory peritoneal dialysis catheter insertion...

ER stress has emerged as a signaling platform underlying the pathogenesis of various kidney diseases. Thus, there is an urgent need to develop ER stress biomarkers in the incipient stages of ER stress-mediated kidney disease, when a kidney biopsy is not yet clinically indicated, for early therapeutic intervention. Cysteine-rich with EGF-like domains 2 (CRELD2) is a newly identified protein that is induced and secreted under ER stress. For the first time to our knowledge, we demonstrate that CRELD2 can serve as a sensitive urinary biomarker for detecting ER stress in podocytes or renal tubular cells in murine models of podocyte ER stress-induced nephrotic syndrome and tunicamycin- or ischemia-reperfusion-induced acute kidney injury (AKI), respectively...

BACKGROUND: Intravesical Bacilli Calmette-Guerin (IVBCG) therapy for non-muscle invasive bladder cancer (NMIBC) has long been in use successfully. Albeit rarely, we still face with its safety concerns more than 25 years on since its approval by US Food and Drug Agency in 1990. Local and systemic infection following intravesical BCG is widely reported as compared to immune mediated local or systemic hypersensitivity reactions involving kidneys; acute kidney injury (AKI) and other renal manifestations are well reported but not of chronic kidney disease (CKD)...

The association between DM and left ventricular diastolic dysfunction, assessed using the ratio of peak early transmitral filling wave velocity (E) to early diastolic velocity of mitral annulus (Ea), with cardiovascular (CV) outcomes in patients with chronic kidney disease (CKD) remains uncertain. This study included 356 CKD stage 3-5 patients underwent echocardiography. All patients were classified into four groups based on the presence of DM and E/Ea ≤ or > 9. CV events included CV death, hospitalization for heart failure, unstable angina or nonfatal myocardial infarction, sustained ventricular arrhythmia, transient ischemic attack, and stroke...

Background: Association between poor control of glycemia and the onset of microvascular complications in type 2 diabetes mellitus (T2DM) patients is a hard issue. However, it seems that the impact of pharmacological treatment is important only in early stages of diabetic nephropathy. We sought to examine whether intensive glycemic control is associated with improvement of clinical Chronic Kidney Disease (CKD) outcomes compared to standard glycemic control. Methods: Meta-analysis of published and unpublished randomized controlled trials (RCT) and post-hoc analysis of RCTs comparing anti-diabetic drugs and/or insulin (intensive control) vs...

A major impediment in the success of cell therapy for neurodegenerative diseases is the poor survival of grafted cells in the in vivo milieu, predominantly due to accumulated reactive oxygen species, thus prompting the search for suitable alternatives. Accumulating evidence suggests that the therapeutic potential of transplanted cells is partially attributed to the secretome released by them into the extracellular milieu. Studies that investigated the neuroprotective potential of the secretome attributes to the mere presence of growth factors without addressing other underlying cellular/molecular changes that occur upon post-secretome intervention like re-establishing the host cell's free radical scavenging machineries...

BACKGROUND: Diabetic kidney disease (DKD) is the leading cause of end-stage renal disease in the Western world. Early and accurate identification of DKD offers the best chance of slowing the progression of kidney disease. An important method for evaluating risk of progressive DKD is abnormal albumin excretion rate (AER). Due to the high variability in AER, most guidelines recommend the use of more than or equal to two out of three AER measurements within a 3- to 6-month period to categorise AER...

Diabetic nephropathy (DN) also named diabetic kidney disease (DN) is one of the leading causes of mortality in people with diabetes. The aim of this review is to update the medical literature, the theories behind its early natural history, the pathways of its pathogenesis, its diagnosis and treatment. Poor glycemic control, hyperlipidemia, smoking, oxidative stress, accumulation of advanced glycated end products, environmental, genetic and epigenetic factors play an important role in the pathophysiological development of DN...

To evaluate RNA oxidation in the early stage of diabetic nephropathy, we applied an accurate method based on isotope dilution high-performance liquid chromatography-triple quadruple mass spectrometry to analyze the oxidatively generated guanine nucleosides in renal tissue and urine from db/db mice of different ages. We further investigated the relationship between these oxidative stress markers, microalbumin excretion, and histological changes. We found that the levels of 8-oxo-7,8-dihydroguanosine (8-oxoGuo) and 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) were increased in the urine and renal tissue of db/db mice and db/db mice with early symptoms of diabetic nephropathy suffered from more extensive oxidative damage than lean littermate control db/m mice...
