Effect of Hemodialysis on Upper Airways Collapsibility in Patients With Chronic Kidney Disease
Renal InsufficiencyChronicIntroduction: Currently, chronic kidney disease (CKD) is one of the most serious public health problems, becoming a global epidemic. It is also known that the amount of displacement of overnight rostral fluid, from the lower limbs, is related to increased neck circumference and severity of obstructive sleep apnea (OSA) in patients with end-stage renal disease. Method / Design: A clinical trial study aiming to assess the degree of collapsibility of the upper airway in patients with CKD undergoing hemodialysis has been proposed. The test of the negative expiratory pressure and nocturnal polysomnography will be performed before and after the hemodialysis session. Discussion: The incidence of CKD has increased, due to the increased number of cases of diabetes mellitus and hypertension. Our hypothesis is that the weight gain due to volume overload, observed in the interdialytic period, will exert a negative influence on the degree of collapsibility of the upper airways predispose to OSA in CKD patients.
Pharmacokinetic Comparison Of All FK-506 Formulations

Dexmedetomidine and Renal Transplants
Renal FailureInvestigators aim to retrospectively research patients undergoing renal transplants that received dexmedetomidine perioperatively to see if dexmedetomidine use protects renal function. Investigators hope to elucidate any association between renal transplant patients and perioperative dexmedetomidine administration, these include (but are not limited to) UOP, Cr/GFR, morbidity, mortality, in hospital complications and failure rate. Investigators will research both living and cadaveric renal transplants.
Study on Colonic Fermentation in Chronic Kidney Disease Patients
Renal InsufficiencyChronicChronic kidney disease is associated with the accumulation of various metabolites, i.e., uremic retention solutes. Evidence is mounting that the colonic microbiome contributes substantially to these uremic retention solutes. Indoxyl sulfate and p-cresyl sulfate are among the most extensively studied gut microbial metabolites, and are associated with cardiovascular disease, chronic kidney disease progression and overall mortality. Indirect findings suggest that chronic kidney disease influences the colonic microbial metabolism with higher p-cresyl sulfate urinary excretion rates at more advanced renal disease. Therefore, this study aims to elucidate the influence of renal dysfunction on microbial metabolism and to test the hypothesis that chronic kidney disease patients carry a different fecal metabolite profile.

Study of the Bioaccumulation of Tinzaparin in Renally Impaired Patients When Given at Prophylactic...
Renal InsufficiencyChronic2 moreThe purpose of this study is to assess if accumulation of anti-Xa activity occurs after repeated daily administration of prophylactic doses of tinzaparin in patients with severe chronic kidney disease (CKD) requiring thromboprophylaxis for non-surgical conditions. It is anticipated that tinzaparin used at a fixed dose for thromboprophylaxis in severe CKD patients (eGFR ≤ 30 ml/min /1.73 m2) at risk for venous thromboembolism (VTE) will not bioaccumulate at a significant level, meaning an increase of ≥ 20% of the anti-Xa mean level between day 2 or 3 and day 5.
Carnitine, Aclycarnitine, Myocardial Function, and CRRT
Acute Renal FailureCarnitine is essential for the transport of fatty acids into the mitochondria and energy production in different muscles, including the myocardium. It is also needed to protect myocyte cell membranes from oxidative damage by removing excess acyl carnitine groups. Patients receiving chronic intermittent hemodialysis (HD) are known to be at increased risk for carnitine deficiency as a result of its removal during the dialysis procedure, lack of endogenous synthesis by the kidney, and inadequate dietary intake. The carnitine status of children undergoing continuous renal replacement therapy (CRRT) has not been studied. Children undergoing CRRT in the intensive care unit (ICU) setting may be at increased risk for carnitine deficiency due to its continuous removal, lack of carnitine production by the kidney, and absence of carnitine intake (as majority of these children can not eat and there is no carnitine added to total parenteral nutrition (TPN). Carnitine deficiency may increase the risk of cardiac dysfunction in critically ill children. This is the first study to examine carnitine status in children undergoing CRRT. Standard echo as well as more sensitive speckle tracking echo will be used to evaluate the effect of carnitine deficiency on myocardial function.
Observational Study to Evaluate the Time to Achieving the Maintenance Dose of Zemplar® (Paricalcitol...
Kidney FailureChronicThis observational study will evaluate the clinical benefit of Zemplar (paricalcitol injection) in daily routine practice in end-stage renal disease patients with severe over-reactivity of parathyroid glands. Participants will be followed for 6 months. Data will be collected from participants initiated on Zemplar therapy according to standard of care. The time to achieving the maintenance dose of Zemplar (paricalcitol injection), the proportion of participants achieving target parathyroid hormone levels, and prevalence of elevated serum calcium and phosphate levels will be evaluated.
