End-stage renal failure (ESRF) in diabetic patients, mostly type 2, has become the most frequent cause of renal replacement therapy in western Europe. The majority of patients with type 2 diabetes and renal failure suffer from diabetic glomerulosclerosis, but nondiabetic renal disease and atypical presentations, e.g. as irreversible acute renal failure or ischaemic nephropathy, play an increasingly important role. Known risk factors for the onset of diabetic nephropathy include (1) genetic predisposition (indicated by a history of hypertension and cardiovascular events in first-degree relatives), (2) quality of glycaemic control, (3) level of blood pressure, and (4) smoking. At the time when type 2 diabetes is diagnosed, an abnormal blood pressure profile is found in approximately 80%. In patients with established diabetic nephropathy, hypertension is the most important factor which promotes progression, and this is susceptible to intervention. Although less data are available for type 2 diabetes (compared with type 1 diabetes), ACE inhibitors appear to be the antihypertensive agent of first choice, but monotherapy is rarely sufficient to achieve the blood pressure goal. Although, at least in principle, diabetic nephropathy is a preventable condition, currently only a minority of type 2 diabetic patients in western Europe receives adequate medical treatment to prevent onset or progression of diabetic nephropathy. Consequently, novel approaches to patient management and interdisciplinary interaction are necessary to fulfil the postulate of the St Vincent declaration concerning prevention of diabetic complications.

A 38-year-old otherwise healthy man presented with hepatic failure (aspartate aminotransferase of 7212 U/L, alanine aminotransferase of 6629 U/L, total and direct bilirubin of 10.7 mg/dL) and acute renal failure (creatinine of 11.6 mg/dL and blood urea nitrogen of 42 mg/dL), which required hemodialysis when the creatinine increased to 21 mg/dL, with a blood urea nitrogen of 115 mg/dL, and the patient became oliguric. On admission, this patient also had a lipase of 1833 U/L, amylase of 211 U/L, glucose of 210 mg/dL, and reactive IgM antibody for acute hepatitis A. The hepatitis and acute renal failure resolved in 3 months, but this patient continues to have type II diabetes mellitus 7 years after the hepatitis A infection. This case illustrates that hepatitis A infection may be severe with liver failure, acute renal failure, and permanent diabetes mellitus as sequale of this infection.

Metformin is an oral hypoglycemic agent belonging to the class of biguanides that are commonly used in the treatment of type II diabetes mellitus. Lactic acidosis is a rare but severe adverse reaction that occurs primarily in patients with contraindications such as renal failure. The case of a 71-year-old woman with type II diabetes, in whom severe metformin-associated lactic acidosis was precipitated by acute renal failure in the absence of pre-existing chronic renal failure or other absolute contraindications to biguanide use, is presented. Aggressive correction of the acidosis and prolonged dialysis resulted in a favourable outcome despite severe acidosis. The present case report shows that metformin-associated lactic acidosis can occur in patients without pre-existing renal insufficiency. Metformin should be temporarily stopped when acute renal failure occurs or is anticipated.

Low birth weight due to premature birth or to intrauterine growth retardation adversely affects normal renal development. In the period immediately after birth, the short-term renal-related consequences of low birth weight are an increased risk of acute renal failure as well as transient imbalance of fluid and electrolyte homeostasis. Epidemiological studies show that low birth weight adults are at risk of developing chronic renal disease. There are thought to be several causes for this phenomenon. Adult low birth weight subjects have an increased incidence of hypertension and type 2 diabetes, both of which are well-established risk factors for chronic renal injury. Moreover, interference with normal kidney development, as seen in low birth weight babies, results in a lower than normal number of nephrons, which might also play a role in the renal disturbances.

Drugs that inhibit the renin-angiotensin system (RAS) are of proven benefit in the treatment of hypertension, congestive heart failure, or acute myocardial infarction. In the last decade, several clinical trials have shown that RAS inhibitors also offer significant renoprotection in both diabetic and non-diabetic nephropathy. However, patients with advanced renal insufficiency did not take part in these trials because of the risk of acute renal failure (ARF) and hyperkalemia, and, for the same reason, most physicians do not offer these drugs to patients with impaired renal function. Recently, a post-hoc analysis of the Ramipril Efficacy In Nephropathy (REIN) study which included patients with severe renal insufficiency, showed that RAS inhibition slows glomerular filtration rate (GFR) decline over time and progression to end-stage renal disease (ESRD) in a safe way in patients quite close to ESRD (basal GFR, 10 to 30 ml/min/1.73m2). These beneficial effects have also been shown in the Reduction of Endpoints in NIDDM with the All Antagonist Losartan (RENAAL) study, in patients with type 2 diabetes mellitus, clinical proteinuria, and renal insufficiency, where RAS inhibition therapy significantly reduced the risk of ESRD once doubling of baseline serum creatinine levels had been achieved as compared to non-RAS anti-hypertensive treatment. Thus, these data suggest that RAS inhibition therapy should be given to all patients with proteinuric chronic nephropathy, independently of the level of renal function.

Metformin belongs to a class of drugs known as the biguanides that are widely used in the treatment of type 2 diabetes mellitus. Its association with lactic acidosis is well established, although rare. Metformin-associated lactic acidosis is recognized as a potentially lethal condition that can occur in patients with contraindications to the drug, such as renal dysfunction, liver diseases, alcoholism, and cardiopulmonary diseases. In these cases, the plasma concentration of metformin is not necessarily abnormally high. We describe a 75-year-old diabetic woman with acute renal failure and life-threatening lactic acidosis due to metformin intoxication. Clinical manifestations included vomiting, diarrhea, hypothermia, hypotension and transitory blindness. Her initial renal function was recovered after hemodialysis and she was discharged 3 months after admission.

Two pathological patterns of acute poststaphylococcal glomerulonephritis are well defined and include (1) an acute proliferative and exudative glomerulonephritis closely resembling classical acute poststreptococcal glomerulonephritis in patients with Staphylococcus aureus infection and (2) a membranoproliferative glomerulonephritis in patients with Staphylococcus epidermidis infection secondary to ventriculovascular shunts. In this study, we report a novel immunopathologic phenotype of immunoglobulin (Ig) A-dominant acute poststaphylococcal glomerulonephritis occurring in patients with underlying diabetic nephropathy. Five patients with type 2 diabetes presented with acute renal failure occurring after culture-positive staphylococcal infection. Renal biopsy disclosed an atypical pattern of acute endocapillary proliferative and exudative glomerulonephritis with intense deposits of IgA as the sole or dominant immunoglobulin, mimicking IgA nephropathy. The deposits were predominantly mesangial in distribution with few subepithelial humps. All five cases occurred superimposed on well-established diabetic nephropathy. Outcome was poor with irreversible renal failure in four of five (80%) cases. The possible pathophysiological basis of this atypical form of acute poststaphylococcal glomerulonephritis in diabetic patients is explored. Proper recognition of this entity is needed to avoid an erroneous diagnosis of IgA nephropathy, with corresponding therapeutic and prognostic implications.

Lactic acidosis is a serious clinical situation associated with a high case fatality rate. Lactic acidosis is particularly found in conditions with an insufficient supply of oxigen in the tissue. Other causes for lactic acidosis can be hepatic or renal insufficiency. For the therapy of overweight patients with type 2 diabetes metformin is the first choice if diet and physical training have been ineffective. Metformin, however, has the potential to increase serumlactate. Therefore its ability to cause lactic acidosis is controversely discussed. We present a 64-year-old female patient with metformin-associated lactic acidosis. She had several pre-existing risk factors to develop a lactic acidosis. On her referral to the hospital she suffered from acute renal failure which is considered to be a contraindication for the use of metformin.

Patients with diabetes mellitus are at increased risk for repeat interventions and mortality after coronary angioplasty and stenting. The efficacy of sirolimus-eluting stents (SESs) to improve the outcomes of these patients is a focus of interest. In the first 1,407 patients treated with SESs at our institution, 492 were diabetic (insulin dependent diabetes mellitus [IDDM], n = 160 and non-insulin-dependent DM [NIDDM], n = 332). The in-hospital and 1- and 6-month clinical outcomes were compared with those of 915 patients without DM (non-DM). The baseline characteristics were similar, except for more women, obesity, previous myocardial infarction, coronary artery bypass grafting, and renal insufficiency in the DM group (p <0.001). Compared with non-DM patients, DM patients had higher in-hospital (p <0.05) and 1-month mortality (p = 0.02). IDDM patients had more in-hospital renal failure (p = 0.04) and Q-wave myocardial infarctions (1.6% vs 0%, p = 0.04) compared with NIDDM patients, and higher mortality (3.1% vs 0.8%, p = 0.04) and subacute stent thromboses (2.3% vs 0.5%, p = 0.07) than non-DM patients at 30 days. At 6 months, DM patients had a higher incidence of Q-wave myocardial infarction, target lesion revascularization-major adverse cardiac events, and composite of death and Q-wave myocardial infarction than non-DM patients (6.0% vs 2.7%, p = 0.01). Late outcomes between the IDDM and NIDDM groups were similar. Multivariate analysis showed diabetes and acute renal failure as independent predictors of target lesion revascularization-major adverse cardiac events. In conclusion, our data showed that, despite a reduction in repeat revascularization, coronary intervention with SESs in diabetic patients is limited by higher mortality at 1 month and a higher incidence of Q-wave myocardial infarction and target lesion revascularization-major adverse cardiac events at 6 months compared with non-DM patients. Careful surveillance is required in IDDM patients undergoing SES implantation.

In most Western countries, diabetic nephropathy (DN) has become the single most common condition found in patients with end-stage renal disease (ESRD). This is to some extent due to better survival of diabetic patients with renal failure, but mostly due to the dramatic increase in the prevalence of type 2 diabetes. The majority of type 2 diabetic patients with renal failure suffer from nodular glomerulosclerosis (Kimmelstiel-Wilson); but ischemic nephropathy, irreversible acute renal failure (mostly acute on chronic) and diabetes co-existing with primary renal diseases are common as well. Classical DN evolves in a sequence of stages. After a period of glomerular hyperfiltration, increased urinary albumin excretion [microalbuminuria (MA)] i.e. 30-300 mg/day or 20 - 200 microg/minute indicates the onset of overt DN. Risk factors for development of DN are positive family history, hyperglycemia in the mother during pregnancy, high blood pressure, obesity and insulin resistance. Poor glycemic control (HbAlc) and elevated systolic blood pressure (> 135 mm Hg) interact in enhancing the risk of DN. Proteinuria and smoking are major promoters of progression. The risk of onset of microalbuminuria can be reduced by lowering of blood pressure and specifically by blockade of the renin angiotensin system (RAS). In patients with established DN, the target systolic blood pressure should be <130 mm Hg and RAS blockade is obligatory. Treating all cardiovascular risk factors is a high priority. Antihypertensive management is rendered difficult by extreme volume sensitivity, pronounced activation of the RAS and autonomic neuropathy. Cardiac events are excessively frequent, glycemic control becomes difficult and autonomic diabetic neuropathy with gastroparesis and diabetic foot are additional problems. Hemodialysis or continuous ambulatory peritoneal dialysis should be started relatively early. In the absence of contraindications, transplantation (renal transplantation, combined kidney/pancreas transplantation or pancreas after kidney transplantation) is the treatment of choice.
