Active clinical trials for "Renal Insufficiency"

It is generally assumed that renal blood flow is symmetric in the absence of renal artery stenosis. The importance of studying the function of both kidneys separately is because it cannot be assumed that they are functionally equal.The aim of the present study is to evaluate whether this is really in patients with essential hypertension and/or moderate kidneys loss.

The purpose of this observational study is to better understand the natural history/natural course of uremic pruritus (UP) - itching associated with chronic kidney disease(CKD). During the lifetime of a CKD dialysis patient, UP tends to be a prolonged, frequent, and an intense itch that is known to impair the patient's quality of life (QoL), including sleep and mood. The study will follow hemodialysis (HD) patients longitudinally to characterize their pruritus over time. The study will quantify and characterize UP and assess change over time; collect data on conditions that may be affected by UP such as sleep, mood, socialization and overall quality of life; collect data on use of medications, particularly anti-pruritic treatments, sleep aids, and medications for depression and anxiety; and collect data on medical resource use, particularly hospitalizations for treatment of skin and other infections over the duration of the study.

We previously reported early measurement of urinary MDA might be a useful marker for the prediction of CDDP-induced renal damage in rat. The purpose of this clinical study is to test whether the changes of human urinary excretion of MDA, and can be used as early biomarker for the prediction of development of CDDP-induced ARF.

The purpose of this study is to evaluate the urinary excretion and renal metabolism of vitamins, in particular vitamin B12 and folate, in relation to various renal conditions involving loss of renal function and/or proteinuria.

The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.

Assessment of meropenem plasma concentration in critically ill patients who require CRRT (continuous renal replacement therapy). A standard dose of meropenem is administered, i.e. 1 gram every 8 hours.

The purpose of this study is to determine whether urinary connective tissue growth factor (uCTGF) can predict the onset of fibrosis in transplanted kidneys.

The location of the catheter tip in radiographic planes 1 and 2, is a protection factor for the mechanical performance of peritoneal Dialysis. Instead radiographic planes 3 and 4 are risk factors.

Acute renal failure (ARF) is a frequent complication in the postoperative cardiac surgery, and is a major risk factor for mortality in this context. The right ventricular dysfunction post cardiopulmonary bypass (CPB) is also a common complication, close to 100% if one takes into account the transient dysfunction. A recent study showed that right ventricular dysfunction and the IRA seemed related, rather on the slope of venous congestion. We wish to study this phenomenon more specifically in particular to offer reliable diagnostic markers of venous congestion.

This study is designed for volume assessment in pediatrics during major surgery using non-invasive tools as ultrasonography without the need of invasive techniques avoiding its complications and as a guide for fluid therapy needed for maintaining adequate hemodynamics
