BACKGROUND: Cardiovascular disease (CVD) begins early in children with chronic kidney disease (CKD), and its progression is determined by the presence of single or multiple cardiovascular risk factors (CVRFs). OBJECTIVE: To determine the prevalence of CVRFs in children with CKD and their association with mortality in children on chronic dialysis. METHODS: This comparative cross-sectional study recruited children aged 5 - 18 years with all stages of CKD...

PURPOSE: Serum calcium and phosphorus abnormalities are associated with cardiovascular disorders in general population, but evidence among patients with established coronary heart disease (CHD) is limited and controversial. This study aimed to investigate the associations of baseline serum calcium and phosphorus levels with long-term mortality risk among patients with CHD. METHODS: We conducted a prospective cohort study among 3187 patients with CHD from October 2008 and December 2011 in China...

The term "vitamin D" refers to two chemical compounds - ergosterol, or vitamin D2, and cholecalciferol, or vitamin D3. Active vitamin D3 is correctly regarded as a neurohormone due to its pleiotropic biological activities. Although the relation between vitamin D and calcium-phosphorus metabolism has never been discussed, the knowledge on many other roles vitamin D plays is growing fast. Briefly, vitamin D immunomodulation includes attenuation and stimulation of Th1 and Th2 cell proliferation, respectively. Similarly, vitamin D can induce or inhibit the synthesis, secretion, and release of anti- inflammatory (IL-4 and IL-10) and pro-inflammatory (IL-1, TNF-α, IFN-γ) cytokines, respectively...

BACKGROUND: Vascular calcification is common among patients with chronic kidney disease (CKD), and it is associated with all-cause and cardiovascular disease mortality. Deoxycholic acid, a metabolite of circulating bile acids, is elevated in CKD and induces vascular mineralization and osteogenic differentiation in animal models. STUDY DESIGN: Cohort analysis of clinical trial participants. SETTING & PARTICIPANTS: 112 patients with moderate to severe CKD (estimated glomerular filtration rate, 20-45mL/min/1...

OBJECTIVES: While maintenance of both phosphorus concentration and nutritional status is a major concern in managing haemodialysis patients, the interaction between these parameters is not well understood. The aim of this study was to assess whether or not nutritional index influences the association between phosphorus concentration and all-cause mortality. DESIGN: A cohort study. SETTING: The Dialysis Outcomes and Practice Pattern Study, which included 99 representative dialysis facilities in Japan between 1997 and 2010...

BACKGROUND: Elastase-1 is a proteolytic enzyme secreted by pancreatic acinar cells, and measurements of the concentration this enzyme are used to evaluate pancreatic exocrine function. We aimed to determine whether pancreatic exocrine function declines due to chronic hypercalcemia by measuring fecal elastase levels. METHODS: 75 patients with primary hyperparathyroidism (18 men and 47 women) and 30 healthy subjects (11 men and 19 women) participated in this study...

Multiple pharmacological applications of osthole have been previously recognized, including antioxidant, anti-inflammatory, anti‑platelet and estrogenic effects, and resistance to pain. The present study investigated the protective effects of osthole against inflammation in a rat model of chronic kidney failure (CRF) and the underlying mechanisms. Osthole treatment with significantly reversed CRF‑induced changes in serum creatinine, calcium, phosphorus and blood urea nitrogen levels in CRF rats. Male Sprague‑Dawley rats (age, 8 weeks) received 200 mg/kg 2% adenine suspension to induce CRF in the model group...

We aim to evaluate the disturbances in mineral metabolism, abnormalities in bone mineral density (BMD), and extraskeletal calcification in newly detected, untreated predialysis stage 4 and 5 chronic kidney disease (CKD) patients at a tertiary care hospital in North India. This is cross-sectional observational study. A total of 95 (68 males, 27 females) newly detected patients underwent clinical evaluation, biochemical assessment [serum calcium, phosphorus, alkaline phosphatase (ALP), albumin, creatinine, intact parathyroid hormone (iPTH), 25- hydroxyvitamin D (25(OH)D)], BMD measurement (at spine, hip, and forearm) by dual-energy X-ray absorptiometry (DXA), lateral abdominal radiograph [for abdominal aortic calcification (AAC)], skeletal survey (to look for any abnormality including fractures), and echocardiography [for any cardiac valvular calcification (CVC)]...

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in patients with end-stage renal disease. Chronic kidney disease (CKD)-associated cardiovascular mortality is more prevalent in those with diastolic heart failure and is an early predictor, while increased left ventricular mass (LVM) is a strong independent risk factor. Hypovitaminosis D is extensively being studied as a nontraditional risk factor for CVD. The aim of the present study is to look at the association of Vitamin D and other parameters of mineral bone disorder (MBD) with diastolic dysfunction and LVM in nondiabetic young adult patients with CKD...

The use of antidiabetic drugs is expected to substantially increase since diabetes mellitus incidence rises. Currently used antidiabetic drugs have a positive safety profile, but they are associated with certain acid-base and electrolyte abnormalities. The aim of the review is to present the current data regarding the antidiabetic drugs-associated acid-base and electrolyte abnormalities. Areas covered: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been linked with the scarce, but serious, complication of euglycemic diabetic ketoacidosis, as well as with an increase in serum potassium, magnesium and phosphorus levels...

Hypophosphatasia (HPP) is a rare inborn error of metabolism due to a loss-of-function mutation in the gene for tissue nonspecific isoenzyme of alkaline phosphatase (ALP) that results in low levels of ALP. The clinical presentation of HPP is variable and in adults can easily be misdiagnosed as other forms of osteomalacia. We present a case of a 53-year-old Caucasian female who was evaluated for recurrent metatarsal fractures. She reported her first metatarsal fracture at age 21, and since then had at least 8 more metatarsal fractures over her lifetime, most without injury other than weight bearing...

By using an experimental model of dexamethasone-induced osteoporosis we investigated the effects of different therapeutic schemes combining sodium alendronate (SA) and simvastatin on bone mineral and protein composition, microstructural and mechanical remodeling. Wistar rats were randomized into eight groups: G1: non-osteoporotic; G2: osteoporotic; G3, G4, and G5: osteoporotic+SA (0.2, 0.4, and 0.8 mg/kg, respectively); G6, G7, and G8: osteoporotic+SA (0.2, 0.4, and 0.8 mg/kg, respectively)+simvastatin (0.4, 0...

OBJECTIVE: To evaluate the outcome of bone metabolism and bone mineral density (BMD) in haemodialysis patients after parathyroidectomy (PTX). METHODS: A total of 31 haemodialysis patients with secondary hyperparathyroidism (SHPT) were treated with PTX. BMD of lumbar spine (LS) and femoral neck (FN) was determined by dual energy X-ray absorptiometry. RESULTS: Parathyroidectomy ledds to significant decrease of serum β-crosslaps (β-CTX), osteocalcin (OC) and procollagen type I amino-terminal propeptide (PINP) while serum sclerostin (SOST) increased after surgery...

Vitamin D has immunomodulating properties. The nuclear receptor for vitamin D is expressed in several immune cells, which convert 25-hydroxyvitamin D (25OHD) to the active form 1,25 hydroxyvitamin D [1,25(OH)2 D]. Under conditions of infection, 1,25(OH)2 D promotes production of cathelicidin (an antimicrobial peptide) in monocytes and activated macrophages. In vitro studies have shown the ability of cathelicidin to inhibit replication of human immunodeficiency virus (HIV-1) in T CD4 lymphocytes and macrophages...

BACKGROUND: The cardiorenal syndrome (CRS) is a major health problem in our aging population. The term was introduced to cover disorders of the kidneys and heart, whereby dysfunction of one organ may induce dysfunction of the other. As the natural history of the CRS is mostly slow, hence difficult to explore in clinical trials, adequate animal models combining cardiovascular and renal disease are required. Therefore, we developed and characterized a usable model for CRS type 4, i.e. chronic kidney disease (CKD) causing cardiac dysfunction...
