Acute kidney injury (AKI) is a multifactorial entity that occurs in a variety of clinical settings. Although AKI is not a usual reason for intensive care unit (ICU) admission, it often complicates critically ill patients' clinical course requiring renal replacement therapy progressing sometimes to end-stage renal disease and increasing mortality. The causes of AKI in the group of ICU patients are further complicated from damaged metabolic state, systemic inflammation, sepsis, and hemodynamic dysregulations, leading to an imbalance that generates oxidative stress response...

Protein-bound uremic toxins, indoxyl sulfate and p-cresol sulfate, increase oxidative stress and adversely affect chronic kidney disease progression and cardiovascular complications. In this study, we examined whether mitochondria are the target of indoxyl sulfate and p-cresol sulfate intoxication in vivo and in vitro. The kidneys of 10-week-old male B-6 mice with ½-nephrectomy treated with indoxyl sulfate and p-cresol sulfate were used for the animal study. Cultured human renal tubular cells were used for the in vitro study...

The metabolism of a typical Western diet generates 50-100 mEq of acid (H+) per day, which must be excreted in the urine for the systemic acid-base to remain in balance. The 2 major mechanisms that are responsible for the renal elimination of daily acid under normal conditions are ammonium (NH4+) excretion and titratable acidity. In the presence of systemic acidosis, ammonium excretion is intensified and becomes the crucial mechanism for the elimination of acid. The impairment in NH4+ excretion is therefore associated with reduced acid excretion, which causes excess accumulation of acid in the body and consequently results in metabolic acidosis...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited cause of end-stage renal failure. Understanding the molecular and cellular pathogenesis of ADPKD could help to identify new targets for treatment. The classic cellular cystic phenotype includes changes in proliferation, apoptosis, fluid secretion, extracellular matrix and cilia function. Hoever, recent research, suggests that the cellular cystic phenotype could be broader and that changes, such as altered metabolism, autophagy, inflammation, oxidative stress and epigenetic modification, could play important roles in the processes of cyst initiation, cyst growth or disease progression...

PURPOSE OF REVIEW: This article reviewed very recent papers (2016) discussing or bringing clinical evidences of the possible common pathways leading to diabetic foot syndrome (DFS) and increased mortality rates. RECENT FINDINGS: Diabetic patients with diabetic foot syndrome have a mortality rate greater than twofold when compared with non-ulcerated diabetics. In addition, the 5-year mortality rate following amputation is estimated at 39-68%, a life expectancy comparable to aggressive types of cancer or advanced congestive heart failure...

Diabetic kidney disease (DKD) is the leading cause of ESRD; however, early intervention can greatly prevent the progression of DKD; thus, sensitive biomarkers for DKD are still required. This study was aimed at the identification of potential biomarkers and revelation of underlying pathways in DKD patients by non-targeted metabolomics. Gas chromatography-mass spectrometry was used to analyze urine obtained from the control and type 2 diabetes mellitus (T2DM) and DKD patients, and the renal histological changes in DKD patients were assessed...

Diabetic kidney disease (DKD) is a chronic renal microvascular complication associated with abnormal glucose metabolism, which is an important cause of end stage renal disease. Diabetes can damage the kidney through many ways, including renal vascular, glomerular, tubular, and renal interstitial damages. Therefore, a comprehensive treatment process must be taken for the treatment of DKD, and the selection of appropriate drugs has important significance in the treatment of DKD. Berberine has significant curative effect in the treatment of DKD, and the mechanism is related to the reduction of blood sugar, improvement of renal hemodynamics abnormality, regulation of blood lipid profile and the attenuation of systemic and local inflammation...

Diabetic nephropathy (DN) is a common cause of chronic kidney disease and end-stage renal disease, which can be triggered by oxidative stress. In this study, we investigated the renoprotective effect of the ethyl acetate extract of Salvia miltiorrhiza (EASM) on DN and examined the underlying molecular mechanism. We observed that EASM treatment attenuated metabolic abnormalities associated with hyperglycemic conditions in the experimental DN model. In streptozotocin (STZ)-induced mice, EASM treatment reduced albuminuria, improved renal function and alleviated the pathological alterations within the glomerulus...

Life expectancy in patients with all stages of chronic kidney disease (CKD) falls far short of that in the general population. Cardiovascular disease is the leading cause of mortality in pediatric patients with CKD. In contrast to the intimal atherosclerotic lesions that characterize cardiovascular disease in the general population, vascular endothelial dysfunction, medial arterial calcification, and cardiac dysfunction contribute to cardiovascular pathological conditions in CKD. The pathogenesis of these lesions, the origins of which can be identified in the absence of traditional cardiovascular risk factors, is incompletely understood...

Chronic kidney disease (CKD) is a progressive condition marked by protracted kidney damage which over time can lead to end stage renal disease (ESRD). CKD can be categorized into different stages based on the extent of renal damage and degree of renal dysfunction with ESRD requiring renal replacement therapy considered the final stage. It is important to note that CKD in all of its forms is associated with accelerated atherosclerosis, cardiovascular (CV) disease and poor CV outcomes. While a number of factors contribute to the high risk of CV mortality in this patient population, dyslipidemia is considered to be a key player in the pathogenesis of CV disease in CKD...

Pseudoxanthoma elasticum (PXE) is an inherited metabolic disease with autosomal recessive inheritance caused by mutations in the ABCC6 gene. Since the first description of the disease in 1896, alleging a disease involving the elastic fibers, the concept evolved with the further discoveries of the pivotal role of ectopic mineralization that is preponderant in the elastin-rich tissues of the skin, eyes and blood vessel walls. After discovery of the causative gene of the disease in 2000, the function of the ABCC6 protein remains elusive...

Aluminum (Al) is one of the most extended metals in the Earth's crust. Its abundance, together with the widespread use by humans, makes Al-related toxicity particularly relevant for human health.Despite some factors influence individual bioavailability to this metal after oral, dermal, or inhalation exposures, humans are considered to be protected against Al toxicity because of its low absorption and efficient renal excretion. However, several factors can modify Al absorption and distribution through the body, which may in turn progressively contribute to the development of silent chronic exposures that may lately trigger undesirable consequences to health...

Oxalate, a non-essential end product of metabolism, causes hyperoxaluria and eventually calcium oxalate (CaOx) stone disease. Kidney cells exposed to oxalate stress results in generation of reactive oxygen species (ROS) and progression of stone formation. Perturbations in endoplasmic reticulum (ER) result in accumulation of misfolded proteins and Ca(2+) ions homeostasis imbalance and serve as a common pathway for various diseases, including kidney disorders. ER stress induces up-regulation of pro-survival protein glucose-regulated protein 78 (GRP78) and pro-apoptotic signaling protein C/EBP homologous protein (CHOP)...

Acute hypokalemic paralysis is a rare and potentially fatal condition, with few related causes, one of which highlights distal renal tubular acidosis (dRTA). Distal renal tubular acidosis is a rare complication of several autoimmune diseases such as systemic lupus erythematosus, Sjögren's syndrome, and Hashimoto thyroiditis. We report a case of a lupic patient who presented rapidly progressive quadriparesis in the context of active renal disease. Research revealed severe refractory hypokalemia, metabolic acidosis, and alkaline urine suggestive of dRTA...

Neurological manifestations related to electrolyte disorders, drug toxicity, and uremia are common in chronic kidney disease (CKD). Seizures and coma are frequent complications of acute renal insufficiency (uremia), whereas peripheral neuropathy and encephalopathy, observed in progressive uremia, are terminal events. Failure to excrete metabolic products causes their accumulation and can lead to severe intoxication. Clinically, the signs and symptoms of uremia can vary widely, depending on the biological characteristics of the patient, the specific type of renal disease, and the time of the uremic intoxication...

Chronic diabetes is associated with metabolic and haemodynamic stresses which can facilitate modifications to DNA, proteins and lipids, induce cellular dysfunction and damage, and stimulate inflammatory and fibrotic responses which lead to various types of renal injury. Approximately 30-40% of patients with diabetes develop nephropathy and this renal injury normally progresses in about a third of patients. Due to the growing incidence of diabetes, diabetic nephropathy is now the main cause of end-stage renal disease (ESRD) worldwide...

In DM2, there is increased expression of the proximal glucose transporter SGLT2. The increased glucose reabsorption from the urine to the proximal tubule and subsequently to the bloodstream, has three direct effects on the prognosis of patients with DM2: a) it increases the daily glucose load by raising the renal threshold for glucose, thus augmenting requirements for oral antidiabetics and insulin. This progressive increase occurs throughout the course of the disease and in parallel with the increase in renal mass (renal hypertrophy); b) because of the greater glucose reabsorption, glycosuria is lower than the level corresponding to glycaemia, decreasing the stimulus on the tubuloglomerular feedback system of the distal nephron...

BACKGROUND: Retinopathy of prematurity (ROP) still represents one of the leading causes of visual impairment in childhood. Systemic propranolol has proven to be effective in reducing ROP progression in preterm newborns, although safety was not sufficiently guaranteed. On the contrary, topical treatment with propranolol eye micro-drops at a concentration of 0.1% had an optimal safety profile in preterm newborns with ROP, but was not sufficiently effective in reducing the disease progression if administered at an advanced stage (during stage 2)...

Renal transplantation is the best treatment for patients with end-stage renal disease. Over the last decades, the introduction of new immunosuppressive agents resulted into the reduction of the incidence of acute rejection and early graft loss. Despite this progress, there has been little improvement in the average life of the transplant. The main reasons of late failure are patient's death due to several complications (e.g. cancer, infectious or metabolic), and progressive deterioration of renal function caused by immunological and non-immunological factors...
