A new machine learning approach for predicting the response to anemia treatment in a large cohort of End Stage Renal Disease patients undergoing dial…
2015
Chronic Kidney Disease (CKD) anemia is one of the main common comorbidities in patients undergoing End Stage Renal Disease (ESRD). Iron supplement and especially Erythropoiesis Stimulating Agents (ESA) have become the treatment of choice for that anemia. However, it is very complicated to find an adequate treatment for every patient in each particular situation since dosage guidelines are based on average behaviors, and thus, they do not take into account the particular response to those drugs by different patients, although that response may vary enormously from one patient to another and even for the same patient in different stages of the anemia. This work proposes an advance with respec…
Incidence, risk factors, and prognosis of gastrointestinal hemorrhage complicating acute renal failure.
2001
Incidence, risk factors, and prognosis of gastrointestinal hemorrhage complicating acute renal failure. Background Few prospective data are currently available on acute gastrointestinal hemorrhage (AGIH) as a complication of acute renal failure (ARF). The aim of the present study was to define incidence, sources, risk factors, and outcome of AGIH in patients with ARF. Methods We performed a prospective study on an inception cohort of 514 patients admitted for ARF to a nephrology intermediate care unit. Data on clinical risk factors for bleeding, frequency of occurrence of AGIH, length of hospital stay, and in-hospital mortality were collected. Independent predictors of AGIH were identified.…
Management of Kidney Transplantation in a Factor VII-Deficient Patient: Case Report
2012
Transplantation in patients with congenital bleeding disorders is a challenge requiring an integrated approach of various specialists. Renal transplantation, the most frequent type of solid organ transplantation, is rarely performed in individuals with congenital hemorrhagic disorders. We performed a renal transplantation in a 53-year-old man with end-stage renal disease and congenital coagulation factor VII deficiency, a rare bleeding disorder with a peculiar clinical picture requiring replacement therapy in surgical interventions. Perioperative bleeding was successfully prevented by administration of recombinant activated factor VII. Treatment schedule, administration rate, and long-term …
Chronic renal failure: leukocyte rheology and polymorphonuclear cytosolic Ca2+ concentration.
2000
In a group of subjects with chronic renal failure (CRF), we evaluated the leukocyte rheological activity, expressed as the filtration rate, the polymorphonuclear (PMN) membrane fluidity and the PMN cytosolic Ca2+ content. Using the St. George's Filtrometer, we determined the filtration rate of unfractionated, mononuclear and PMN leukocytes. Using the fluorescent probe 1.4-(trimethylamino)-phenyl-4-phenyl-hexatriene (TMA-DPH), we examined the PMN membrane fluidity and, using the Fura 2-AM, the PMN cytosolic Ca2+ content. From the results obtained, it is evident that only the initial relative flow rate of unfractionated leukocytes was significantly reduced in subjects with CRF, while the filt…
Impact of end-stage renal disease care in planned dialysis start and type of renal replacement therapy--a Spanish multicentre experience.
2006
Background. Timely referral, preparation and initiation of dialysis remain problematic issues. The purpose of this study is to analyse the effect of chronic renal disease care and education on the mode of dialysis start (planned vs non-planned) and on the modality of renal replacement therapy (RRT). Methods. A total of 1504 patients from 35 hospitals started RRT in 2003. Out-patient, scheduled initiation of dialysis with a permanent vascular or peritoneal access was considered planned. Results. About 46% of the patients started non-planned dialysis. Of all the patients, 75% had 3 months of nephrological follow-up, but nearly half were never educated on dialysis options. Haemodialysis (HD) o…
Elastase, myeloperoxidase, nitric oxide metabolites and oxidative status in subjects with clinical stable chronic renal failure on conservative treat…
2009
We evaluated, in a group of 41 CRF undialyzed subjects (29 men and 12 women, mean age 64.1 +/- 11.3 years), some parameters that reflect leukocyte activation (elastase, myeloperoxidase - MPO), plasma NO metabolites (NO(x)) and the oxidative status (lipid peroxidation expressed as thiobarbituric acid-reactive substances (TBARS) and total antioxidant status (TAS). Elastase was determined, on plasma separated from fasting venous blood, as elastase/alpha1-proteinase inhibitor complex. MPO was evaluated employing the Myeloperoxidase ELISA kit. The NO production was evaluated by a micromethod. The oxidation of polyunsaturated fatty acids was evaluated in plasma by detection of the thiobarbituric …
Assessment of cerebral microbleeds by susceptibility-weighted imaging at 3T in patients with end-stage organ failure
2018
Purpose: Cerebral microbleeds (CMBs) are small rounded lesions representing cerebral hemosiderin deposits surrounded by macrophages that results from previous microhemorrhages. The aim of this study was to review the distribution of cerebral microbleeds in patients with end-stage organ failure and their association with specific end-stage organ failure risk factors. Materials and methods: Between August 2015 and June 2017, we evaluated 15 patients, 9 males, and 6 females, (mean age 65.5 years). Patients population was subdivided into three groups according to the organ failure: (a) chronic kidney failure (n = 8), (b) restrictive cardiomyopathy undergoing heart transplantation (n = 1), and (…
Accumulation of hydroxyethyl starch (HES) in the liver of patients with renal failure and portal hypertension
1986
Summary Hydroxyethyl starch (HES) has gained wide clinical acceptance as a colloidal plasma substitute. We were able to study the liver biopsies of two patients with renal failure who developed ascites after repeated infusions of HES. All types of liver cells displayed massive accumulation of HES with the morphologic resemblance to a storage disease. These changes could be distinguished clearly from the lesions of a hereditary disorder by light and electron microscopy. Although it is difficult to establish a causative role for HES in the development of ascites on the bases of morphological changes alone, one should be cautious about giving HES to patients with renal failure until exact data…
Xerostomia, thirst, sodium gradient and inter-dialytic weight gain in hemodialysis diabetic vs. non-diabetic patients
2017
Background In hemodialysis (HD) patients, xerostomia and hyposalivation may intensify sensations of thirst, and contribute to the intake of fluids and excessive inter-dialytic weight gain (IWG). Since IWG is regarded to be higher in diabetic patients than in non-diabetics HD enhancing their mortality, it is crucial to define plausible underlying causes. Therefore, the study investigates factors contributing to the increased IWG in diabetic HD patients. Material and Methods The study included 97 HD patients (38 diabetics) receiving hemodialysis. All participants completed surveys comprising the Dialysis Thirst Inventory (DTI) and Xerostomia Inventory. Unstimulated whole saliva flow rate (USW…
Inappropriately high left ventricular mass: Marker of very high cardiovascular risk in patients with chronic kidney disease
2012
There is increasing knowledge of the burden of cardiovascular (CV) diseases affecting patients with chronic kidney disease (CKD). CV diseases are the main cause of death in the CKD population, and the majority of patients with CKD die before ever reaching the end-stage renal disease; in fact, for patients with CKD, the risk of a fatal CV event is much higher than the risk to develop end-stage renal disease. Although patients with CKD manifest a high prevalence of traditional CV risk factors, this does not fully account for the burden of CV diseases in CKD.
