Active clinical trials for "Renal Insufficiency"

Arterial hypertension causes adverse effects on the entire cardiovascular system, with effects centrally such as diastolic dysfunction and structural changes of the left ventricle and, peripherally such as endothelial dysfunction and increased thickness of the vessels. Co-existing diseases, such as diabetes mellitus, renal dysfunction, sleep apnea, etc. further aggravate the prognosis of these patients. In addition the rate of patients aged > 65 years suffering from un-diagnosed or diagnosed arterial hypertension was 78% for women and 64% for male patients. This population consists from elderly or very elderly patients (over 65 and 80 years respectively) who exhibit more comorbidities and probably less compliance with antihypertensive therapy. Finally, at every age the disease and its effects can affect the quality of life of patients. The main purpose of this study is to investigate the efficacy of antihypertensive therapy (irbesartan alone or in combination with amplodipine and carvedilol) on the cardiovascular system (diastolic left ventricular function, the function of the endothelium (FMD) and the thickness of the common carotid artery). The secondary objective of the study is to monitor the quality of life (Quality of Life - QoL) of patients. Additionally the investigators will seek the correlation of results with co-morbidities, compliance, and patient age.

The aim of this post-marketing observational study is to obtain further data on the long term use, safety and efficacy of Zemplar as it is prescribed in the normal clinical setting and according to the approved Summary of Product Characteristics for the treatment of secondary hyperparathyroidism in hemodialysis patients in Greece.

Critically ill patients in the intensive care unit often receive continuous hemodialysis to treat their kidney failure. Ertapenem is an antibiotic often used in these patients. Continuous dialysis may remove ertapenem, putting patients at risk for inappropriate treatment of their infection. This study will determine how much ertapenem is removed by continuous hemodialysis.

Investigate, through a randomized, open, parallel and comparative, non-inferiority of heparin sodium produced by laboratory Hipolabor compared to heparin manufactured by APP in patients on hemodialysis due to renal failure, through the control of hemostasis, verified by formation of clot (fibrin) in the hemodialysis system and pharmacodynamic parameters (TTPA and Anti-Xa) during the use of heparin

The are 2 principal goals in this study: To measure plasma copeptin levels in healthy subjects and to correlate them with plasma AVP concentrations and urine osmolalities in iso-, hypo-, and hyperosmolar states. To measure plasma copeptin concentrations in patients with chronic renal failure under the same conditions described above, in order to characterize the impact of renal function on circulating copeptin levels in correlation to plasma AVP and urine osmolality.

The influence of hemodialysis on oxidative stress, endothelial activation, inflammation and on the redox state of lymphocytes should be clarified as well as the putative relationships between all these parameters.

Low molecular weight heparins (LMWH) have been shown to be at least as efficient and safe as unfractioned heparin (UFH) in prophylaxis and treatment of venous thromboembolic events and in therapy of acute cardiovascular diseases. LMWH are widely used as safe replacement of oral anticoagulation with vitamin K antagonists (VKA). Due to their pharmacokinetic characteristics, LMWH tend to accumulate in patients with impaired renal function. Official guidelines recommend therefore to use LMWH controlled by Anti-Xa levels or to use UFH instead of LMWH to provide full therapeutic anticoagulation therapy in patients with severe renal insufficiency. Although dosage recommendations have been proposed for enoxaparin in patients with renal impairment based on several studies, these data cannot be applied to other LMWH directly due to different pharmacokinetic properties of each drug. The present study aims to clarify the pharmacokinetics of dalteparin in patients with renal insufficiency, especially addressing the question of accumulation after multiple doses and including patients with severe renal insufficiency and derive a safe and suitable concept for using dalteparin in patients with impaired renal function.

The purpose of this study is to determine whether sodium bicarbonate is effective in the prevention of sodium-induced nephropathy

The aim of the study is to describe the current clinical management of young children with urinary tract infections in Dutch primary care and also to describe the possibilities for improvement and potential cost-efficiency of improved care in the light of preventing renal failure.

Patients presented with unexplained elevated serum creatinine including vast varieties of acute or chronic kidney disease. Renal biopsy may include acute and chronic interstitial nephritis, glomerulosclerosis and tubular atrophy, acute tubular necrosis, rapidly progressive glomerulonephritis, granulomatous glomerulonephritis, monoclonal gammopathy, myeloma kidney or thrombotic microangiopathy . Renal biopsy definitely still plays the most vital and irreplaceable role in the investigations of cases with unexplained renal impairment. Despite a vastly variable biopsy results between patients, renal biopsy has helped in determining the best treatment and prognosis for the patients.
