110 individuals with stage 4-5 Chronic Kidney Disease (CKD) will be randomized to 1-year of blinded Evolocumab or placebo. Subjects will undergo evaluation of circulating lipids at baseline and end of study. A substudy including 50 subjects will assess myocardial rest and stress positron emission tomography (PET) at baseline and at 1-year.

Rationale: The humoral and cellular immune response after two mRNA vaccinations is severely attenuated in kidney transplant patients compared to controls, especially when their immunosuppressive regimen contains mycophenolate mofetil (MMF) / mycophenolic acid (MPA). A repeated dose strategy is therefore required to improve the efficacy of vaccination. Objective: To investigate the immunogenicity of third or fourth dose SARS-CoV-2 vaccination strategies in kidney transplant patients. Study design: Prospective, multicentre, open-label randomized clinical trial Study population: Patients with a functioning kidney transplant who did not seroconvert after two or three doses of a mRNA vaccine (either mRNA-1273 (Moderna) or BNT162b2 (Pfizer) or any combination of both) Procedures: Based on their immunosuppressive treatment, patients can participate in one of the following strata: stratum A: patients receiving triple immunosuppressive therapy, consisting of a calcineurin inhibitor, MMF/MPA, and steroids In stratum A, patients will be randomized to one of two equally sized groups. Patients will receive a third or fourth vaccination of the mRNA-1273 vaccine (100 μg, i.m), with either continuation of MMF/MPA (A1) or discontinuation of MMF/MPA during one week before and one week after the third or fourth dose, respectively (A2). stratum B: patients receiving any combination of immunosuppressive drugs. In stratum B, patients will be randomized to one of three equally sized groups. Patients will receive another dose (100 μg, i.m) of the mRNA-1273 vaccine (B1), or two single doses of mRNA-1273 into the left and the right upper arm (2 x 100 μg, i.m; B2), or the Ad26.COV2.S vaccine (Janssen, 5x1010 viral particles, i.m; B3). Main study parameters/endpoints: The primary endpoint is the proportion of patients with an anti-S1 antibody concentration higher than 10 BAU/mL established at 28 days after the third or fourth vaccine administration. Within each stratum different vaccination strategies will be compared. Secondary endpoints include: concentration of anti-S1 antibodies in serum at 28 days after the 3rd or 4th vaccine administration concentration of virus-neutralizing antibodies in serum SARS-CoV-2 specific T cell responses safety in terms of incidence of acute rejection and solicited local and systemic adverse events (AEs) after vaccination. antibody (IgG and IgA) responses in nasal mucosal fluid

The objective of this study was to evaluate the role of curcuminoids in the prevention of CI-AKI in CKD patients.The result of the study was prophylactic administration with curcuminoids in addition to standard treatment reduce the incidence of CI-AKI CKD patients undergoing elective CAG.

In this study, Vigileo is used to guide hydration adjustment, and SCr is used to estimate renal function. The aim of the study is to investigate the preventive effect of adequate hydration guided by Vigileo on contrast induced nephropathy in patients with acute myocardial infarction who undergo PCI.

This is a Phase 1b, single-center, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effect of RBT-9 in healthy volunteers and in subjects with Stage 3-4 CKD.

Current study will render insight in to the role of renal hypoxia in the diabetic kidney and is able to associate its finding with measurements of renal perfusion and glomerular filtration rate. Moreover, this research will focus on the effects of sodium-glucose cotransporter 2 inhibition on renal tissue oxygenation and oxygen consumption as well as a change in intrarenal hemodynamics and perfusion, and a shift of fuel metabolites. Elucidation the mechanisms underlying the effects of SGLT2 inhibition will advance our knowledge and contribute to their optimal clinical utilization in the treatment of chronic kidney disease in diabetes and possibly beyond.

Secondary hyperparathyroidism (sHPT) is common in patients with chronic kidney disease (CKD), including those who are undergoing long-term haemodialysis treatment. sHPT is characterized by persistently elevated levels of parathyroid hormone (PTH) and major disturbances in phosphorus and calcium metabolism. When glomerular filtration rate (GFR) falls, the phosphorus clearance decreases significantly, leading to phosphorus retention. The resulting hyperphosphatemia is thought to be one of the principal causes of secondary hyperparathyroidism which is a very early complication of patients with CKD. Its diagnosis and treatment is crucial in the management of such patients.The treatment of the sHPT of CKD's patient includes dietary phosphate restriction, the use of phosphate binders, correction of hypocalcaemia, the use of vitamin D and its derivatives. The calcimimetic agent cinacalcet hydrochloride may be also used in combination with vitamin D. While the majority of patients can be controlled in this way, medical therapy is not always successful in achieving adequate control of secondary hyperparathyroidism. Oral medications (calcimimetics, recently developed phosphate binders, and active vitamin D derivatives amount to very high monthly costs, and have efficacy limitations as well as side-effects. HIFU may become a valuable alternative treatment that help control secondary hyperparathyroidism in selected patients presenting with enlarged parathyroid gland(s) visible at ultrasonography,. The aim of this study is to evaluate the efficacy and safety of HIFU treatment in chronic haemodialysis patients with secondary hyperparathyroidism presenting with enlarged parathyroid gland(s) which are visible at ultrasonography and for whom medical therapy has been unsuccessful.

This study will be an open-label, single-treatment, single-dose, parallel group study to evaluate the pharmacokinetics (PK) of droxidopa in subjects with mild, moderate, and severe renal dysfunction and End Stage Renal Disease (ESRD) after a single dose compared to matched healthy subjects with normal renal function. A total of 48 male or female subjects, 16 subjects with normal renal function (eGFR greater than 90 mL/min/1.73m²) and eight each (8) with mild (60 less than eGFR less than 89 mL/min/1.73m²), moderate (30 less than eGFR less than 59 mL/min/1.73m²), or severe (15 less than eGFR less than 29 mL/min/1.73m²) renal impairment or ESRD (eGFR < 15 mL/min/1.73m² and requiring hemodialysis) will be selected according to the inclusion and exclusion criteria. The medical and laboratory examinations will take place within 28 days before dosing. A single dose of 600 mg of droxidopa as an investigational drug will be administered with 240 mL of water after an overnight fast (minimum 10 hours). Blood samples for the measurement of plasma concentrations of droxidopa and metabolites including but not limited to 3-OM-DOPS, NE, vanillic acid, and protocatechuic acid will be collected before and 0, .5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 24, 30, 36 hours after dosing for healthy volunteers and subjects with mild, moderate, and severe renal impairment and those with ESRD. For the latter, samples will be collected on both a non-hemodialysis and a hemodialysis visit. During dialysis, samples of dialysate, from the arterial and venous sides of the dialyzer will be collected at 30-minute intervals during the dialysis period. In addition, the entire dialysate will be collected, its volume recorded, and a sample retained for the measurement of droxidopa and metabolites including but not limited to 3-OM-DOPS, NE, vanillic acid, and protocatechuic acid concentrations. Urine samples for the measurement of urinary excretion of droxidopa and metabolites including but not limited to 3-OM-DOPS, NE, vanillic acid, and protocatechuic acid will be collected before and over the following intervals after dosing: 0 2, 2-4, 4-6, 6-8, 8-12, 12-24, and 24-36 hours for healthy volunteers and subjects with mild, moderate, and severe renal impairment. A post-study visit with physical examination and laboratory tests will take place within seven (7) days after the last PK blood sampling.
