Filter by:Bone disorder is a significant problem in chronic kidney disease (CKD), becoming almost universal in stage 5 CKD patients. Besides the healthcare costs, bone disorder is associated with life-threatening complications, including fractures and cardiovascular (CV) events. Kidney transplantation provides circa 68% decrease in mortality and improves co-morbidity. Still, bone disease persists after transplantation. The investigators hypothesize that bone-derived hormones can induce CV events in kidney transplanted patients. Therefore, early evaluation of the bone health is recommended, and prevention of its complications is required. Bone biopsy, an invasive and expensive method, is the gold standard for bone disorders diagnosis. Therefore, non-invasive predictors for bone disease are necessary. Classical biochemical markers of bone formation and resorption have shown a low sensitivity and low specificity. New markers, as fibroblast growth factor 23 (FGF23), and its cofactor klotho, and sclerostin are promising new markers for predicting CKD-associated bone and CV disease after transplantation. This study assesses the phenotype of bone disease after transplantation (given by bone histology) and its correlation with serum FGF23, klotho and sclerostin, in order to evaluate its performance predicting CKD-associated bone and CV disease.
Central venous catheters (CVCs) are used for vascular access by approximately 56% of our 380 hemodialysis (HD) patients at the Capital Health Renal Program. The major complication of these catheters includes thrombosis and infection. Catheter locking solutions such as recombinant tissue plasminogen activator (rt-PA), Alteplase (Cathflo®) are used to treat and prevent clotting of the catheter during HD treatments and during the interdialytic period. Evidence to guide the use of rt-PA is limited. This quality assurance project will compare the effectiveness and cost of an intensive versus a standard catheter dysfunction protocol for rt-PA in HD patients.
Food intake has a deep influence on gut microbiota composition and function, both in health and in disease status. In chronic kidney disease (CKD), a microbiota dysbiosis status is observed. Moreover, many toxic uremic molecules are microbial-derived and their accumulation promotes, in turn, disease progression. Investigators' hypothesis foresees a beneficial effect of nutritional treatments, able to restore gut microbiota balance, to lower microbial-derived uremic toxins and to improve clinical conditions in CKD patients. Mediterranean Diet (MD) is supposed to have beneficial effect on microbiota composition, while low-protein diet supplemented with ketoacids (KD) is used in CKD patients for the improvement of clinical conditions, but its effects on gut microbiota are currently unknown. Investigators' project aim is to verify the effects of MD and KD on: microbiota and metabolome composition, microbial-derived uremic toxins level and clinical conditions in a cohort of CKD patients.
Kidney disease is a common problem after heart transplantation. It may be caused by anti-rejection medications such as cyclosporine or tacrolimus. However, the reason why some people develop kidney problems after a heart transplant, but other people do not, is not fully known. This study plans to learn more about the relationship between a person's genetic make-up (DNA; deoxyribonucleic acid) and the risk of kidney problems after a heart transplant. The long-term goal of this research is to identify genetic variations that may help predict the development of kidney problems after heart transplantation.
This study will investigate whether inspiratory muscle training in patients with end stage renal failure can improve strength and function.
The purpose of this study is to determine whether the use of a very low protein diet is effective in delaying the start of chronic dialysis treatment in patients affected by chronic kidney disease (CKD).
