BACKGROUND: Renal fibrosis (RF) is a well-known marker for chronic kidney disease (CKD) progression, including chronic renal injury after renal transplantation. However, invasive biopsy is an available examination for evaluation of RF. Diffusion MRI was once recognized as a promising option for RF. However, it is now controversial for RF evaluation in a unilateral ureteral obstruction (UUO) model. METHODS: To seek an optimal imaging method applicable for RF in UUO model kidneys, we attempted a series of MRI methods, including proton density-weighted imaging, T1-weighted imaging, T2-weighted imaging, T2*-weighted imaging, diffusion-weighted imaging, and diffusion tensor imaging (DTI)...

Patients with chronic kidney disease (CKD) demonstrate complex mineral metabolism derangements and a high prevalence of vitamin D deficiency. However, the optimal method of 25-hydroxyvitamin D (25(OH)D) repletion is unknown, and trials analysing the comparative efficacy of cholecalciferol and ergocalciferol in this population are lacking. We conducted a randomised clinical trial of cholecalciferol 1250μg (50 000 IU) weekly v. ergocalciferol 1250μg (50 000 IU) weekly for 12 weeks in forty-four non-dialysis-dependent patients with stage 3-5 CKD...

Previous studies have shown a higher prevalence of malignancy in patients with diabetes mellitus (DM) and chronic kidney disease (CKD). The purpose of this study was to investigate the prevalence of adenomatous colon polyps (ACP) as they occur in subjects with DM and coexisting CKD. This is a retrospective cohort study of patients with DM (n=565) who had undergone colonoscopy between 2000-2010. The cohort was further bifurcated into those with CKD (n=296) and those with normal renal function (n=269). Presence or absence of ACP was measured in both groups...

OBJECTIVES: Chronic impaired renal function (IRC) constitutes a major risk factor of morbi-mortality during the treatment of an abdominal aortic aneurism (AAA). The inflammatory state due to the AAA could result in a reduction in the muscular mass and an over-estimation of the glomerular filtration rate (GFR) with the usual formulas. The objective of this study was to determine if the formulae used to evaluate the estimated GFR were adapted in patients with AAA. MATERIALS AND METHODS: Between August 2013 and November 2014, we conducted an exploratory study to evaluate the renal function before surgery for AAA in 28 patients...

Thoracic aortic aneurysms rupture and dissection are among the most devastating vascular diseases, being characterized by elevated mortality, despite improvements in diagnostic imaging and surgical techniques.An increased aortic root diameter (ARD) represents the main risk factor for thoracic aortic dissection and rupture and for aortic valve regurgitation.Even though arterial hypertension is commonly regarded as a predisposing condition for the development of thoracic aorta aneurysms, the role of blood pressure (BP) as determinant of aortic root enlargement is still controversial...

BACKGROUND: Patients with chronic kidney disease (CKD) have a high symptoms burden that is related to a poor health-related quality of life (HRQoL) and high costs of care. Validated instruments may be useful for assessing the symptoms and monitoring outcomes in these patients. The Palliative care Outcome Scale-Symptoms Renal (POS-S Renal) is a patient-reported outcome measure for assessing symptoms in CKD stage 4-5. This study is the first cross-cultural adaptation and psychometric analysis of this clinical tool...

Cardiovascular (CV) risk assessment is not easy in chronic kidney disease (CKD) patients. Age, male sex, race, family history of CV disease, smoking status and diabetes should be considered as CV risk factors as the general population. It is also accepted that hypertension (HTN) is associated with the greater risk of CV complications in this population. However, there are some concerns in this issue.First, supporting evidence for specific blood pressure (BP) targets in CKD is scarce. Many observational studies reported a J-shaped association between BP level and CV mortality unlike a linear association in the general population...

Prediction models are often developed in and applied to CKD populations. These models can be used to inform patients and clinicians about the potential risks of disease development or progression. With increasing availability of large datasets from CKD cohorts, there is opportunity to develop better prediction models that will lead to more informed treatment decisions. It is important that prediction modeling be done using appropriate statistical methods to achieve the highest accuracy, while avoiding overfitting and poor calibration...

In the clinic, the pathological types of chronic kidney diseases (CKD) are considered references for choosing treatment protocols. From a statistical viewpoint, a non-invasive method to predict pathological types of CKD is a focus of our work. In the current study, following a frequency analysis of the clinical indices of 588 CKD patients in the department of nephrology, a third-grade class-A hospital, a novel theory is proposed: "bi-directional cumulative probability dichotomy". Further, two models for the prediction and differential diagnosis of CKD pathological type are established...

INTRODUCTION Chronic kidney disease (CKD) is one of the consequences of human immunodeficiency virus-1 (HIV-1) infection. The disease increases the risk of progression to acquired immunodeficiency syndrome and death and complicates antiretroviral therapy. The prevalence of CKD in HIV-1-infected patients is difficult to estimate and depends on the diagnostic criteria for CKD. OBJECTIVES The aim of the study was to evaluate the usefulness of a single measurement of serum asymmetric dimethylarginine (ADMA) levels in the diagnosis of kidney damage in patients infected with HIV-1...

BACKGROUND: Hemodialysis as an efficient therapy for advanced CKD is the most used treatment modality all over the world. Even though primary AVF is widely accepted as a best permanent vascular access in hemodialysis patients, up to 60% of all fistulas fail to mature. The pathogenesis of early fistula failure is not very well understood. Many general and local factors are involved: patient's age, sex, primary renal disease, small vessel's diameter, presence of accessory veins, prior venipunctures, surgical skill, genetics, etc...

OBJECTIVE The authors recently reported that the presence of chronic kidney disease (CKD) and/or extended abdominal aortic calcification was associated with significantly worse clinical outcomes after posterior lumbar interbody fusion. CKD is one of the highest risk factors for systemic atherosclerosis. Therefore, impaired blood flow due to atherosclerosis could exacerbate degeneration of the cervical spine and neural tissue. However, there has been no report of a study evaluating the deleterious effects of CKD and atherosclerosis on the outcomes after decompression surgery for cervical compression myelopathy...
