Diabetic nephropathy (DN) is a renal disease which develops as a consequence of diabetes mellitus. Microalbuminuria is the earliest clinical sign of DN. There are no specific diagnostic biomarkers for type 2 diabetics with nephropathy other than microalbuminuria and macroalbuminuria. However, microalbuminuria does not constitute a sole independent indicator for type 2 diabetics with nephropathy, and thus, another screening method, such as a biomarker assay, is required in order to diagnose it more correctly. Therefore, we have utilized two-dimensional electrophoresis (2-DE) to identify human serum protein markers for the more specific and accurate prediction of progressive nephropathy in type 2 diabetes patients, via comparisons of the serum proteome in three experimental groups: type 2 diabetes patients without microalbuminuria (DM, n = 30), with microalbuminuria (MA, n = 29), and with chronic renal failure (CRF, n = 31). As a result, proteins which were differentially expressed with statistical significance (p < 0.05) in MA and CRF groups as compared to those in DM group were selected and identified by ESI-Q-TOF MS/MS. Among these identified proteins, two proteins which might be useful as diagnostic biomarkers of type 2 diabetics with nephropathy were verified by Western blotting: extracellular glutathione peroxidase (eGPx) and apolipoprotein (ApoE) were found to exhibit a progressive reduction in MA and CRF groups. Notably, eGPx was further verified by ELISA using DM (n = 100) and MA (n = 96) patient samples. Collectively, our results show that the two proteins identified in this study may constitute potential biomarkers for the diagnosis of type 2 diabetics with nephropathy.

This is a cross sectional hospital based study carried out at Om Hospital and Research Center Kathmandu, Nepal. In the study, 200 diabetic patients attending the hospital were taken as the subjects and we evaluated the urinary albumin excretion and other biochemical parameters (such as creatinine, total cholesterol, HDL cholesterol, LDL cholesterol), blood pressure and body mass index (BMI). Among these 200 patients with type 2 diabetes mellitus (DM), 52.0% were having high blood pressure. The proteinuria was present in 23.0% of the overall subjects but when it is categorized in hypertensive and non-hypertensive group, 30.7% of the diabetic patients with hypertension were having proteinuria. It has been found that males were having higher prevalence ofproteinuria (53.8%) than female (17.6%). There was significant difference in systolic blood pressure, diastolic blood pressure in nephropathy and without nephropathy group. Thus the nephropathy or the incidence of proteinuria was associated with obesity, high diastolic blood pressure and male sex. These data suggest that control of diabetes; hypertension should decrease the risk for proteinuria thus decreasing end stage renal disease (ESRD) and mortality from ESRD.

Albuminuria reduction could be renoprotective in hypertensive patients with diabetic nephropathy. However, the current use of renin-angiotensin-system intervention is targeted to BP only. Therefore, this study investigated the adequacy of this approach in 1428 patients with hypertension and diabetic nephropathy from the placebo-controlled Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) study. Investigated were the extent of discordance in treatment effects on systolic BP (SBP) and albuminuria and its association with renal outcome in a multivariate Cox model. Among patients with a reduced SBP during treatment, a lack of albuminuria reduction was observed in 37, 26, and 51% (total, losartan, and placebo, respectively) at month 6. SBP or albuminuria reduction was associated with a lower risk for ESRD, whereas combined SBP and albuminuria reduction was associated with the lowest risk for events. Across all categories of SBP change, a progressively lower ESRD hazard ratio was observed with a larger albuminuria reduction. A lower residual level of albuminuria was also associated with lower ESRD risk. In conclusion, changes in albuminuria are not concordant in a substantial proportion of patients when titrated for BP. Meanwhile, the ESRD risk showed a clear dependence on albuminuria reduction. The ESRD risk also showed dependence on the residual level of albuminuria, even in patients who reached the current SBP target. Antihypertensive treatment that is aimed at improving renal outcomes in patients with diabetic nephropathy may therefore require a dual strategy, targeting both SBP and albuminuria reduction.

The objective of the present study was to determine the frequency of lupus anticoagulant (LA), in patients with terminal chronic renal failure (TCRF), and its association with thrombotic events. Sixty three patients were separated into two groups: Group A, consisted of 32 patients under treatment with hemodialysis, and Group B was formed of 31 patients who were treated in a conservative manner. Presence of LA was found in 4 patients from Group A and none from Group B. Seven thrombotic events were registered, all in patients from Group A, and three of the episodes happened in 2 patients with LA, showing a statistically significant difference with LA negative patients from the same Group A (p < 0.001). Three of the LA positive patients suffered from type 2 diabetes and all of them had been under dialysis for less obtained by than 6 months. Vascular access was catheterization which means that 57.1% of patients with this type of procedure were positive for LA. The present results show a strong relationship between the presence of LA and thrombotic episodes in patients with TCRF, under hemodialysis with the use of catheter, instead of a permanent vascular access. Due to the fact that prolonged use of catheters for hemodialysis has been related to positive LA, it is advisable to screen patients under dialysis for the presence of this antibody, and to promote the prompt availability of a permanent vascular access, in order to prevent complications, such as thrombosis.

Diabetic nephropathy is the leading cause of chronic renal failure (CRF) in Europe. About fifty percent of diabetic subjects develop microalbuminuria, which progresses towards established diabetic nephropathy in one third of patients. The treatment of type 2 diabetes in a patient with CRF is a challenge for the general practitioner, because of the accumulation of drugs and/or specific metabolites. Sulfonylureas are associated with an increased risk of hypoglycaemia. Biguanides may exceptionally cause life-threatening lactic acidosis. Glitazones have an interesting profile since they decrease microalbuminuria and blood pressure. However, their safety is not well defined in the context of CRF In the case of severe CRF, only insulin and repaglinide can be recommended.

There are various etiologies for hypoglycemia in patients with chronic renal failure, and its pathogenesis is complex. Concomitant use of medications is the most common cause. We report a rare case of an 82-year-old woman with type 2 diabetes mellitus in end-stage renal disease undergoing maintenance hemodialysis, who experienced recurrent symptomatic hypoglycemia during treatment with propoxyphene for pain relief. Hypoglycemia occurred simultaneously with elevated levels of serum immunoreactive insulin and C-peptide. After discontinuing propoxyphene, hypoglycemia mitigated and the level of insulin returned to normal range. Our case reminds us that propoxyphene-induced hypoglycemia should not be ignored, especially in hemodialysis patients with cold sweats, agitation and depressed consciousness.

The incidence and prevalence of end-stage renal disease (ESRD) is increasing. Diabetic nephropathy has increased in absolute numbers and as a proportion of patients with ESRD. This is almost totally accounted for by the explosive outbreak of Type 2 diabetes mellitus (DM). The world is in the midst of an epidemic of Type 2 DM and hence this trend is likely to continue for some more time. The contribution of glomerulonephritis as a proportion of patients with chronic renal failure (CRF) has declined due to increase in other causes such as diabetes. The annual incidence of IgA nephropathy, which is also a very common cause of renal insufficiency, has not changed. The incidence of focal segmental glomerulosclerosis is increasing while that of membranoproliferative glomerulonephritis is decreasing. Peak incidence of ESRD due to hypertension has shifted to a higher age-group. The proportion of renovascular disease as a cause of ESRD is also increasing. Human immunodeficiency virus associated nephropathy is the third leading cause of ESRD in African-Americans aged 20-64 years. Other diseases such as analgesic nephropathy and lead nephropathy are slowly disappearing. The significance of elevated body lead in patients with varying degrees of renal insufficiency requires further evaluation. The incidence of CRF is significantly higher in the elderly and hence there is a "graying" of CRF population. Census projections show that this trend will continue into the foreseeable future. The incidence and prevalence of ESRD vary between different populations, countries and within countries. The reason for the variations requires further study.

Diabetic nephropathy is the leading cause of ESRD in the United States. Why the pathogenic mechanisms lead to nephropathy in certain patients with type 1 and 2 diabetes and spare others is unclear, but it is clear that hyperglycemia and glomerular hyperfiltration are important factors. In patients with syndromes of extreme insulin resistance, proteinuric forms of renal disease are common, but it is surprising to find that the renal pathology usually is not diabetic nephropathy. For instance, in the lipodystrophy syndromes, membranoproliferative glomerulonephritis type 1 and type 2, focal segmental glomerulosclerosis, and also diabetic nephropathy are seen. In the syndromes of autoantibodies to the insulin receptor, the various forms of lupus glomerulonephritis are seen. Even in patients with type 2 diabetes, the renal pathology may not be diabetic nephropathy. Therefore, in patients with syndromic forms of insulin resistance and type 2 diabetes, renal biopsy has an important role in defining the pathology that leads to proteinuric nephropathy and in formulating a therapeutic approach. It is the purpose of this article to review these unusual aspects of proteinuric nephropathy in patients with diabetes.

Diabetic nephropathy is the most important cause of ESRD. The aim of this study was to develop a risk score from risk predictors for ESRD, with and without death, in the Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) study and to compare ability of the ESRD risk score and its components to predict ESRD. The risk score was developed from coefficients of independent risk factors from multivariate analysis of baseline variables and equals (1.96 x log [urinary albumin:creatinine ratio]) - (0.78 serum albumin [g/dl]) + (1.28 x serum creatinine [mg/dl]) - (0.11 x hemoglobin [g/dl]). It was robust with respect to severity of nephropathy, gender, race, and treatment group. The risk score for ESRD or death was comparable. The four risk predictors for progression of kidney disease were independent of therapy. For combined treatment groups, the hazard ratio between the fourth and first quartiles of the ESRD risk score was 49.0, as compared with the corresponding hazard ratios for each component: 14.7 for urinary albumin:creatinine ratio, 9.2 for serum creatinine, 5.5 for hemoglobin, and 10.2 for serum albumin. The RENAAL risk scores for ESRD with or without death emphasize the importance of identification of level of albuminuria, serum albumin, serum creatinine, and hemoglobin to predict development of ESRD in patients with type 2 diabetes and nephropathy. Although albuminuria is a strong risk factor for ESRD, the contribution of serum albumin, serum creatinine, and hemoglobin level further enhances prediction of ESRD. Future trials with a similar patient population and outcomes measures should consider adjusting analyses for baseline risk factors.

Renal impairment is frequent in aged diabetic patients, notably with type 2 diabetes. It results from a multifactorial pathogeny, particularly the combined actions of hyperglycaemia, arterial hypertension and ageing. Diabetic nephropathy (DN) is associated with an increased cardiovascular mortality. DN often leads to end stage renal failure (ESRF) which causes specific problems of decision and practical organization of extra-renal epuration in diabetic and aged patients. In the absence of renal biopsy, clinical signs are often insufficient to assess the diabetic origin of a nephropathy in an elderly diabetic patient. Prevention of DN is principally based on tight glycaemic and blood pressure control. The progression of renal lesions can be retarded by strict blood pressure control, notably by blocking of the renin-angiotensin system, if well tolerated in aged patients. It is absolutely necessary to avoid the worsening of renal lesions by potentially nephrotoxic products, notably non steroidal anti-inflammatory drugs (NSAIDs) and iodinated contrast media. At the stage of renal failure, it is important to adapt the antidiabetic treatment, and in the majority of the cases, to switch to insulin when glomerular filtration rate (GFR) is below 30 ml/mn/1.73 m2.
