Successful pregnancy in an end-stage renal disease patient on peritoneal dialysis.

Among women with chronic kidney disease, successful pregnancy with a surviving infant is rather rare. Although these pregnancies carry higher risk, with the possibility of adverse maternal and fetal outcomes, they can be managed with close monitoring and intense renal replacement therapy. Given the hemodynamic advantages of peritoneal dialysis over hemodialysis in pregnancy, peritoneal dialysis therapy is thought to be a favorable renal replacement option in pregnant patients with chronic kidney disease.

The effects of iron on FGF23-mediated Ca-P metabolism in CKD patients.

Background: Fibroblast growth factor 23 (FGF23) is an important counterregulatory hormone for phosphate homeostasis. Since it has been reported that iron administration induces hypophosphatemic osteomalacia by triggering FGF23 synthesis, we hypothesized that iron administration might lead to a further increase in FGF23, resulting in alterations to Ca-P metabolism in a stage 5 CKD population.

Methods: This cross-sectional study was performed in a single center, and involved 73 hemodialysis patients (47.

Protective effect of beta-glucan on contrast induced-nephropathy and a comparison of beta-glucan with nebivolol and N-acetylcysteine in rats.

Background: It has been shown that beta-glucan (BG), which has antioxidant and immunomodulatory effects, attenuats renal ischemia-reperfusion injury. We aimed to investigate whether BG might have a preventive role against the development of contrast-induced nephropathy and to compare its effect with nebivolol (Nb) and N-acetylcysteine (NAC).

Methods: Thirty-six Wistar albino female rats were randomly divided into six groups (n = 6 each): control, contrast media (CM), BG, BG + CM, Nb + CM, and NAC + CM.

Association of the angiotensinogen M235T and APO E gene polymorphisms in Turkish type 2 diabetic patients with and without nephropathy.

Background: Diabetic nephropathy (DN) is a leading cause of diabetes-related morbidity and mortality. The aim of this study was to evaluate the relationship of AGT M235T and apoprotein E (APO E) gene polymorphism with DN in Turkish patients of Type 2 diabetes, and to compare genotype and allele distributions among DN patients, non-DN patients, and healthy controls.

Methods: AGT M235T and APO E genotype and allele analysis were performed in 111 DN patients, 108 non-DN patients, 106 healthy control subjects for APO E genotype, and 100 for AGT M235T genotype polymorphism.

A case of an accelerated uremic neuropathy.

We present a 62-year-old man, with a prior history of diabetes mellitus, atherosclerotic heart disease, and chronic renal failure requiring peritoneal dialysis, who developed accelerated uremic sensorimotor polyneuropathy. Our patient significantly improved after effective hemodialysis. Although renal transplantation is a curable therapy for uremic neuropathy, effective dialysis is still an important treatment for the group of patients who cannot undergo renal transplantation.

Effects of everolimus on cytokines, oxidative stress, and renal histology in ischemia-reperfusion injury of the kidney.

Background: To evaluate the effects of everolimus on renal ischemia-reperfusion injury (IRI).

Methods: Wistar albino rats were divided into control, ischemia-reperfusion (IR), and ischemia-reperfusion/everolimus (IR/eve) groups. Everolimus was administered for seven consecutive days to the IR/eve group prior to injury.

The relationship of visfatin levels to inflammatory cytokines and left ventricular hypertrophy in hemodialysis and continuous ambulatory peritoneal dialysis patients.

Visfatin was recently defined as an adipocytokine; however, the pathophysiological role of visfatin is not completely understood. A few studies suggest that visfatin may be a new proinflammatory adipocytokine. The aim of the present study was to compare serum visfatin levels between hemodialysis and continuous ambulatory peritoneal dialysis (CAPD) patients and evaluate the relationship between visfatin levels to IL-6, TNF-alpha, and left ventricular hypertrophy.

The relationship among asymmetric dimethylarginine (ADMA) levels, residual renal function, and left ventricular hypertrophy in continuous ambulatory peritoneal dialysis patients.

Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of endothelial-based nitric oxide synthase. Its level is increased by end stage renal disease. However, most studies showing an increase in ADMA in dialysis patients have focused on hemodialysis.

TGF-beta1 gene polymorphisms and peritoneal equilibration test results in CAPD patients.

Transforming growth factor-beta1 (TGF-beta1) stimulates the expression of collagen mRNA in cultured human peritoneal mesangial cells, which may predispose them to developing peritoneal fibrosis. Polymorphisms in the signal sequence genetically may be responsible for increased TGF-beta1 production (i.e.

Procalcitonin and conventional markers of inflammation in peritoneal dialysis patients and peritonitis.

Objectives: To determine the significance of a newly described marker of inflammation procalcitonin (PCT), and to investigate its relationship to conventional markers of inflammation, such as C-reactive protein (CRP), fibrinogen, and erythrocyte sedimentation rate (ESR), in patients on peritoneal dialysis (PD) and with peritonitis.

Design: A prospective, observational clinical study.

Setting: The Nephrology Division of a University-affiliated teaching hospital.

Morphologic evidence of subclinical atherosclerosis obtained by carotid ultrasonography in patients with Behcet's disease.

Subclinical atherosclerosis can be demonstrated by measuring the intima-media thickness (IMT) of the carotid arteries by high-resolution B-mode ultrasonography (US). Endothelial injury appears a key event in the atherogenesis. Endothelial cell activation and/or injury are the characteristic features of Behçet's disease (BD).

Angiotensinogen and plasminogen activator inhibitor-1 gene polymorphism in relation to renovascular disease.

The present study was designed to evaluate angiotensinogen (AGT) M235T and plasminogen activator inhibitor-1 (PAI-1) (4G/5G) polymorphisims in relation to the occurrence of atherosclerotic renal artery stenosis (ARAS) and recurrent stenosis. In this study, 30 patients were enrolled after angiographic demonstration of ARAS; 100 healthy subjects for AGT polymorphism and 80 healthy subjects for PAI-1 polymorphism were considered the control group. The patients were followed for a mean 46.

Association between neopterin and carotid intima-media thickness in hemodialysis patients.

Background: Atherosclerotic lesions are heavily infiltrated by macrophages. Neopterin can be used as a marker of the activity of macrophages. Serum neopterin levels were elevated in non-renal patients with atherosclerosis.

Intravenous iron therapy as a possible risk factor for atherosclerosis in end-stage renal disease.

Atherosclerosis is a disease of the arterial wall, with increasing wall thickness representing an early event in the progression of the disease. It has been suggested that iron overload, as assessed by increased serum ferritin concentration, may be a risk factor for atherosclerosis. The aim of this study was to investigate the relationship between the influence of intravenous (IV) iron therapy and ferritin levels and carotid intima media thickness (C-IMT) in dialysis patients.

Elevated cardiac troponin T in hemodialysis patients receiving more intravenous iron sucrose.

Elevated cardiac troponin T (cTnT) has been associated with shorter survival in hemodialysis patients. Moreover, intravenous (IV) iron treatment has been held responsible for oxidative stress and accelerated atherosclerosis in these patients. In the present study, we investigated the relationship between cTnT concentration, IV iron treatment, and parameters of iron status.

The use of granulocyte colony-stimulating factor in a neutropenic renal transplant recipient.

Leukopenia occurring after kidney transplantation is a very dangerous condition. It may increase the risk of severe infections which might lead to septicemia or may result in graft loss because the dose of immunosuppressants must be reduced, so it must be diagnosed and treated as soon as possible. The use of recombinant granulocyte colony-stimulating factor (G-CSF) in renal transplant recipients is a new therapeutic approach.
