Filter by:The aim of the study was to compare the renoprotective effect of a long acting calcium antagonist (nisoldipine) with an angiotensin converting enzyme inhibitor (lisinopril)in type 1 diabetic patients with diabetic kidney disease. In total, 51 patients were randomised to treatment with one of these drugs for 4 years. Changes in kidney function, blood pressure and urinary excretion of albumin were measured every 6 months
The Family Investigation of Nephropathy and Diabetes (FIND)Study is a multi-center consortium. The charge of the consortium is to acquire sets of families with well-characterized diabetic nephropathy, establish a secure master FIND database, and perform a genome scan to identify chromosomal regions linked with diabetic nephropathy.
Protocol Title: Randomized open label study comparing the metabolic control of first Kidney Transplant recipients with Type 2 Diabetes Mellitus (DM) receiving either Prograf or Neoral as part of a ATG induction, prednisone free and blood monitored Cellcept immunosuppressive regimen. PURPOSE This is a single center medical research study to analyze post-transplant kidney recipients with pre-existing type 2 diabetes managed according to the recommended American Diabetes Association (ADA) guidelines. Prograf (Tac) and Neoral (CSA) are the two main medications to prevent rejection after transplantation. However, they may contribute to poorer diabetes control. The purpose of the study is to compare the effects of Prograf and Neoral on the control of Diabetes after kidney transplantation. In addition, all participants in this study will receive Thymoglobulin (anti-lymphocyte globulin) at the time of transplantation instead of long term prednisone (steroids).
Few studies have reported the effect of alpha1-adrenergic antagonists on 24-h blood pressure and regulation of sympathetic nervous activity in hypertensive patients with diabetic nephropathy. Using ambulatory blood pressure monitoring devices equipped with spectral analysis of heart rate variability, we assess the effects of doxazosin on blood pressure in diabetic nephropathy patients and compare the results with those in patients with essential hypertension, patients with diabetes mellitus and patients with chronic nephropathy.
Current research indicates that TTP488 may be a viable agent for the treatment of diabetic nephropathy. The purpose of this study is to determine the safety and efficacy of a six-month regimen of daily orally-administered TTP488 to patients with diabetic nephropathy.
Patients with type 2 diabetes have a long duration of disease for the development of complications. Among all complications, microangiopathic complications are major causes of mortality and morbidity in diabetic patients. In Asia, patients with type 2 diabetes are particularly susceptible to the development of kidney disease. Patients with diabetic kidney disease have more adverse metabolic profiles and increased risk of having other complications such as blindness, stroke, heart attack and nerve damage than those without. Despite receiving the best of care, the combined event rate of death, cardiovascular disease and end stage kidney disease in diabetic patients with renal impairment remained as high as 10% per year. Cilostazol reduces platelet aggregation and prevents formation of blood clots. Furthermore, cilostazol treatment has been shown to reduce serum triglyceride concentrations and increase HDL-cholesterol levels. In this randomized placebo-controlled, double-blinded study, the investigators hypothesize that Cilostazol may reduce the rate of decline in renal function in Chinese patients with type 2 diabetes and mild to moderate renal impairment. Sixty patients will be randomised to receive either Cilostazol 100 mg twice daily or placebo for 12 months. The effect of Cilostazol on the progression of diabetic nephropathy, as defined by rates of decline in glomerular filtration rate, serum creatinine and urinary albumin excretion rate will be measured. The results will provide additional insight on the management of diabetic kidney disease which is prevalent among Chinese diabetic patients in Hong Kong.
Study for the effectiveness of intensive therapy aiming at the remission of diabetic nephropathy
The angiotensin converting enzyme inhibitor drugs are now standard therapy for patients with diabetic nephropathy. The hypothesis of this study is that adding a diuretic agent (furosemide) will decrease the urine protein, which is a sign of disease, more than an angiotensin converting enzyme inhibitor alone.
Background The relationship between long-term heavy lead exposure and chronic interstitial nephropathy is well recognized in the previous literatures. Several epidemiological studies have demonstrated a positive association between blood lead levels and the age related decreases of renal function in the general population and suggested that environmental low-level lead exposure may accelerate the progression of renal function in the healthy persons. In addition, previous our works suggest environmental lead exposure may correlate to progressive renal insufficiency and lead chelation therapy or repeated lead chelation may improve and slow the progressive renal insufficiency in non-diabetic patients with chronic renal diseases. However, Diabetes mellitus is increasing in prevalence worldwide and is currently estimated to affect more than 6.5 percent of the population of the United States. In addition, diabetes is the most common cause of end-stage renal disease in many countries, accounting for about 40 percent of cases. It is still unknown that the relationship between long-term environmental lead exposure and the progressive renal insufficiency in patients with type II diabetes and diabetic nephropathy. Methods Ninety patints with type II diabetes and diabetic nephropathy (serum creatinine levels between 1.5 mg per deciliter and 3.9 mg per deciliter) who have a normal body lead burden and no history of exposure to lead or other metals will be observed for 24 months. Then, about 50 subjects with high normal body lead burdens (at least 80 μg but less than 600 μg) will be randomly assigned to the study and control groups. For three months, the 25 patients in the study group will receive lead-chelation therapy with calcium disodium EDTA weekly until the body lead burden fallsl below 50 μg, and the 25 control group receive weekly placebo. During the ensuing 12 months, the renal function will be regularly followed up every 3 months and EDTA mobilization tests will be assessed every 6 months. If body lead burden of the study group patients increase more than 60μg, the chelation therapy will be performed again until their body burden are less than 60 μg. The primary end point is an increase in the serum creatinine level to 2 times the base-line value during the observation period. A secondary end point is the change in renal function during the follow up period.
This randomized study will test a behavioral intervention, based on social cognitive theory (SCT), to improve regimen adherence in three different groups of people with type 2 diabetes; (1) those with well controlled blood glucoses and no concurrent chronic renal insufficiency, (2) those with less well-controlled glucoses and no chronic renal insufficiency, and (3) those with chronic renal insufficiency regardless of glucose control. The primary aims of this study are to: (1)determine whether the intervention improves behavioral adherence to the diabetes self-management regimen including dietary adherence, physical activity, and capillary glucose self-monitoring; (2)determine whether the intervention improves clinical outcomes; (3) explore the extent to which self-efficacy is a mediator of adherence,(4) explore the extent to which the effectiveness of the intervention varies with respect to glycemic control and nephrovascular complications at baseline, and (5)explore the impact of a variety of covariates on the effectiveness of the intervention. Hypothesis #1 is that intervention group participants will perform better than attention control group participants on various measures of adherence to the diabetes management regimen. Primary adherence variables will be dietary intake, and physical activity. Hypothesis #2 is that intervention group participants will have lower HbA1c levels than attention control group participants.
