(LP299v) is a probiotic strain which influences on the intestinal bacterial flora. This is why, it has been introduced into clinical practice for the prevention and treatment of diarrheal disorders and alleviation of their symptoms in patients during antibiotic therapy. However, the use of probiotics in the prophylaxis of infections (CDI) in these patients is problematic.

Arterial stiffness but not endothelial dysfunction is associated with multidrug antihypertensive therapy and nondipper blood pressure pattern in kidney transplant recipients.

Vascular injury related to chronic kidney disease results in increased arterial stiffness and endothelial dysfunction which may affect arterial blood pressure (BP) and influence patient and graft survival in kidney transplant recipients (KTRs).This cross-sectional study aims to elucidate the relationship between the above-mentioned measures of vascular damage and effectiveness of antihypertensive treatment in KTR.One hundred forty-five KTRs 7.

Plasma marinobufagenin immunoreactivity in patients with chronic kidney disease: a case control study.

Experimental data have shown increased plasma levels of marinobufagenin in kidney failure. In this case-controlled retrospective analysis, we evaluated plasma marinobufagenin immunoreactivity in hemodialysis patients compared with subjects with normal kidney function. Sixty-eight adult hemodialysis patients with chronic kidney disease (34 females and 34 males) as well as 68 age-, gender-, and blood pressure-matched subjects without chronic kidney disease were enrolled.

Type 1 diabetic patients have better endothelial function after simultaneous pancreas-kidney transplantation than after kidney transplantation with continued insulin therapy.

The purpose of this study was to analyse the influence of simultaneous pancreas-kidney or kidney transplantation on endothelial function and systemic inflammation in type 1 diabetic patients with end-stage renal disease. In 39 simultaneous pancreas-kidney, 39 type 1 diabetic kidney and 52 non-diabetic kidney recipients, flow-mediated dilatation was measured. Additionally, blood glycated haemoglobin, serum creatinine and lipids, plasma nitrites [Formula: see text] and nitrates, asymmetric dimethylarginine, soluble vascular cell adhesion molecule-1, intercellular adhesion molecule-1, and E-selectin, high-sensitivity C-reactive protein, tumour necrosis factor-α, interleukin 1β and interleukin 6 concentrations were assessed.

Analysis of Clostridium difficile infections in patients hospitalized at the nephrological ward in Poland.

Background: Few studies have evaluated the incidence and risk factors of Clostridium difficile infection (CDI) in the adult Polish population, in particular in solid organ recipients hospitalized at the nephrological ward.

Aim: The aim of this study was to analyze Clostridium difficile infections (CDI) among patients hospitalized in the Department of Nephrology, Transplantation and Internal Medicine, Medical University of Silesia in Katowice.

Material/methods: Thirty-seven patients with Clostridium difficile infection diagnosed between October 2011 and November 2013 (26 months), identified among a total of 3728 patients hospitalized in this department during this period, were included in this retrospective, single-center study.

The Effect of Lactobacillus plantarum 299v on the Incidence of Clostridium difficile Infection in High Risk Patients Treated with Antibiotics.

Background: Lactobacillus plantarum 299v (LP299v) has been used in order to reduce gastrointestinal symptoms during antibiotic exposure. However, it remains controversial whether or not probiotics are effective in the prevention of Clostridium difficile infections (CDI) among patients receiving antibiotics. The aim of this study was to analyze the CDI among patients receiving antibiotics and hospitalized in the period before and after starting routine use of LP299v as a prevention of this infection.

Serum copeptin level predicts a rapid decrease of overhydration after kidney transplantation.

Background: The assessment of proper hydration status in hemodialysis patients is difficult. None of currently available markers or measures is clinically relevant. Recently, human pre-pro-vasopressin (1-164) split product [copeptin (CPP)] - a new surrogate marker of hydration status - was introduced.

The association of long-functioning hemodialysis vascular access with prevalence of left ventricular hypertrophy in kidney transplant recipients.

Left ventricular hypertrophy (LVH) is frequently observed in chronic dialysis patients and is also highly prevalent in kidney transplant recipients. This study evaluates the impact of long-functioning hemodialysis vascular access on LVH in single center cohort of kidney transplant recipients. 162 patients at 8.

Calcification of coronary arteries and abdominal aorta in relation to traditional and novel risk factors of atherosclerosis in hemodialysis patients.

Background: Process of accelerated atherosclerosis specific for uremia increases cardiovascular risk in patients with chronic kidney disease (CKD) and may be influenced by the different structure of arteries. The study assesses the influence of traditional and novel risk factors on calcification of coronary arteries (CAC) and abdominal aorta (AAC) in hemodialysis patients (HD).

Methods: CAC and AAC were assessed by CT in 104 prevalent adult HD and 14 apparently healthy subjects with normal kidney function (control group).

The lipid story in chronic kidney disease: a long story with a happy end?

Cardiovascular (CV) morbidity and mortality increase with the severity of kidney disease, reaching 30 times higher mortality rates in dialysis patients compared with the general population. Although dyslipidemia is a well-established CV risk factor in the general population, the relationship between lipid disorders and CV risk in patients with chronic kidney disease (CKD) is less clear. Despite the clear evidence that statins reduce the risk of atherosclerotic events and death from cardiac causes in individuals without CKD, the use of statins in patients with kidney disease is significantly less frequent.

[Gene polymorphisms of renin-angiotensin-aldosterone system components and the progression of chronic kidney diseases].

Unlabelled: The renin-angiotensin-aldosterone system (RAAS) plays an important role in the pathogenesis of hypertension as well as cardiovascular diseases and chronic kidney diseases. Among the most frequently studied RAAS gene polymorphisms are the angiotensin-converting enzyme insertion/deletion (I/D), angiotensinogen M235T and angiotensin II receptor type 1 A1166C polymorphisms. A significant correlation was found between the I/D polymorphism and cardiovascular morbidity and mortality rates.

[The influence of selected cytokine gene polymorphisms on the occurrence of acute and chronic rejection and on kidney graft survival].

Genetically determined interindividual differences in the production of mediators of immune response may influence the outcomes of kidney transplantation. Of the cytokine gene polymorphisms that determine the level of gene expression, TNF-a -08G/A, IFN-g +874T/A and microsatellite (CA)n, TGF-b1 +869T/C and +915G/C, IL-6 -174G/C, and IL-10 -592C/A, -819C/T, and -1082G/A seem to have the strongest impact on graft survival. Increased risk of acute rejection (AR) was demonstrated for high-producing genotypes of pro-inflammatory cytokines such as TNF-a and IFN-g, while the association with polymorphisms of TGF-b1 and IL-10 remains unclear.
