Three hundred fifteen (315) elderly (> or = 60 years) patients with clinical renal diseases were evaluated for the evidence of glomerular diseases between November 1998 to June 2002. Glomerular diseases (GN) were observed in 20.6% (65/315) of the elderly patients. The age of the patients (male 56; female 9) ranged between 60-90 (mean 64.17 +/- 3.83) years. The clinical presentation of GN included: nephrotic syndrome 40 (61.5%), acute nephritic syndrome 19 (29.2%), rapidly progressive GN 4 (6.15%) and asymptomatic urinary abnormality 2 (3.0%). Overall, primary and secondary glomerular disease were seen in 47 (72.3%) and 18 (27.6%) elderly patients respectively. Idiopathic membranous nephropathy was the most common GN responsible for nephrotic syndrome in 11 (27.5%) of elderly patients. Diabetic Nephropathy related to type 2 diabetes mellitus was the second common cause 9 (22.5%) of nephrotic syndrome. Amyloidosis was noted in 6 (15%) patients. Nephrotic syndrome was related to leprosy in one patient. Amyloidosis occurred in association with multiple myeloma in 5 and carcinoma colon in 1 patient. Thus, primary and secondary GN were responsible for nephrotic syndrome in 60% and 40% of cases respectively. Endocapillary proliferative GN of post infectious etiology was the most prevalent (82.6%) form of acute GN in our elderly patients. Hypertension occurred in 78.2% of cases and edema in 69.5%. Pulmonary congestion (52.2%) and ARF (73.9%) were the dominant presenting feature of acute GN and 39% of patients required dialytic support. Glomerular crescents were seen in 4 (17.4%) patients with acute glomerulonephritis. Pauci-immune crescentic GN which is the commonest type of acute GN in the elderly in western countries was not observed in this study. Renal biopsy revealed mesangiocapillary GN (1) and mesangioproliferative GN (1) in two patients with asymptomatic urinary abnormalities. Thus, overall spectrum of glomerular disease in the Indian elderly population is similar to that of developed countries except in two ways: (1) post infectious endocapillary proliferative-GN was the commonest type of acute GN (2) rarity or absence of pauci-immune crescentic glomerulonephritis.

Thirty-three patients with type 2 diabetes mellitus (16 men, 17 women) were divided into 3 groups based on urinary excretion of albumin (U-Alb)--group A: U-Alb < 30 mg/d; group B: 30 mg/d < or = U-Alb < or = 300 mg/d; and group C: 300 mg/d < U-Alb. Serum creatinine levels were lower than 2.0 mg/dL in all the subjects. There was no difference in age, sex, therapy, body weight, body mass index (BMI), lean body mass (LBM), or hemoglobin A(1c) (HbA(1c)) levels among the 3 groups. Resting metabolic rate (RMR) (kJ/h/m(2)) and adjusted RMR for lean body mass (kJ/h/m(2)) were significantly increased in group C compared with groups A and B. Hb concentrations, serum albumin levels, and creatinine clearance were much lower in group C than in groups A and B (P < .001). There were no difference in serum urea nitrogen, total cholesterol, cholinesterase and free thyroxine, or plasma insulin-like growth factor I (IGF-I) levels among the 3 groups. Linear regression analysis revealed an inverse correlation between RMR and serum albumin levels, correlation between RMR and U-Alb, and inverse correlation between RMR and Hb concentrations, respectively, in these patients. In conclusion, RMR in diabetic patients correlated directly with U-Alb and inversely with serum albumin and Hb concentration. These findings suggest that RMR is related with urinary albumin loss and anemia in patients with type 2 diabetes mellitus accompanied by diabetic nephropathy.

A 59-year-old woman with chronic renal failure due to type 2 diabetes mellitus (DM) is presented. Her father and a brother had a history of brain tumor. Her blood urea nitrogen and serum creatinine levels were 102 mg/dl and 4.5 mg/dl, respectively. Her serum Ca(2+) and Pi were within the normal range (9.4 mg/dl and 5.4 mg/dl, respectively). Her intact parathyroid hormone (PTH) level was 1 730 000 pg/ml. A (99m)Tc-methoxy-isobutylisonitrile scintigraphy showed high uptake in three parathyroid glands. A magnetic resonance image showed microadenoma in the pituitary gland. The serum gastrin level was high. Genetic examination revealed a mutation of the MEN1 gene (894-9 G --> A). From these findings, she was diagnosed with multiple endocrine neoplasia (MEN) type 1. Subsequently, a parathyroidectomy was performed successfully, a parathyroid gland was transplanted to her right forearm, and her serum Ca(2+) level was controlled at 8.5-9.0 mg/dl. It is very important to identify MEN1 if an end-stage renal disease (ESRD) patient has hyperparathyroidism with multigland involvement. Examination of the MEN1 gene may be valuable to make an accurate diagnosis and choose the appropriate therapy in some ESRD patients with hyperparathyroidism.

To examine a possible association between lipoprotein(a) [Lp(a)] levels and diabetic retinopathy in patients with type 2 diabetes mellitus. 100 type 2 diabetic patients were assessed with the following parameters: age, body mass index, duration of diabetes, blood pressure, fasting plasma glucose, total cholesterol, HDL-cholesterol, triglycerides, blood urea nitrogen, creatinine, Lp(a), and albumin excretion rate (AER). Retinopathy was classified as normal retina (NR), non-proliferative diabetic retinopathy (NPDR), and proliferative diabetic retinopathy (PDR) by an ophthalmologist. The PDR group had higher cholesterol (t=-2.24, p<0.05) and creatinine (z=-2.547, p<0.05) levels than the NPDR group. The PDR group had a higher value of AER (z=-2.439, p<0.01) than the NR group. The possibility of developing diabetic retinopathy after 10 years of diabetes was found to be 6.5 fold high (OR; 6.57, 95% CI 1.74-24.79; p<0.05). The Lp(a) levels were similar in the patients with retinopathy and those without retinopathy. In the study, there was no evidence for a relationship between the serum Lp(a) levels and diabetic retinopathy in type 2 diabetic patients.

Patients with gout are at a high risk for drug-induced complications associated with the use of nonsteroidal anti-inflammatory drugs due to the baseline renal and hepatic abnormalities, metabolic disturbances, and concomitant diseases, such as arterial hypertension or type 2 diabetes mellitus. In this connection, it is expedient to use safer selective cycloxygenase-2 (COG-2) inhibitors. However, there are only single reports dealing with studies of the effectiveness and safety of selective COG-2 inhibitors in gout. The study was undertaken to evaluate the effectiveness and safety of the selective COG-2 inhibitor nimesulide (nimesile) in acute gouty arthritis (GA). Twenty male patients (whose mean age was 51.1 +/- 8.4 years) with PA were examined. Seven patients were found to have monoarthritis of 1 metatarsophalangeal joint, oligoarthritis was present in 9 patients and 4 patients had polyarthritis. The history of arthritis was as long as 6 days in 16 patients and 21-30 days in 4. Nimesulide was given in a dose of 200 mg/day for at least 14 days. The time course of changes in the objective and subjective symptoms of arthritis was studied. The tolerability of the drug was evaluated by its effect on renal (the levels of creatinine and urea, creatinine clearance) and hepatic (alanine transferase (ALT), aspartate transferase (AST), gamma-glutamyltranspeptidase (gamma-GTP)) functions, and blood pressure (BP) [24-hour BP monitoring (24-h BPM) before and after treatment. There were clear positive changes in the major parameters of arthritis: the swelling index was 4.5 +/- 2.7 and 0.5 +/- 0.5 scores before and after treatment, respectively; hyperemia, 3.5 +/- 2.5 and 0.1 +/- 0. 1 scores; articular index, 3.6 +/- 2.0 and 0.7 +/- 0.6 scores; pain (visual analogue scale) when resting, 53.8 +/- 17.6 and 4.7 +/- 4.6 scores, and that when moving, 68.3 +/- 16.0 and 9.0 +/- 8.8 mm, respectively. Negative changes in the levels of creatinine and uric acid and a reduction in creatinine clearance were not observed. There were no increases in the levels of ACT, ALT, gamma-GTP. 24-h BPM did not reveal any significant changes in the mean 24-hour, mean diurnal and nocturnal variables of BP. The 24-hour BP profile became better in some patients. Thus, nimesulide is an effective and safe drug for the treatment of PA.

The Cohen diabetic rat is an experimental model reminiscent of human type 2 diabetes. The aim of this study was to characterize the development of end-organ damage in this model. Cohen diabetic sensitive (CDs) and Cohen diabetic resistant (CDr) rats were fed regular diet or a diabetogenic diet. Glucose tolerance, renal function, and renal and retinal histology were studied at set intervals. CDs fed diabetogenic diet were the only strain that expressed the diabetic metabolic phenotype. In this strain, urinary protein excretion did not increase with the development of diabetes, but plasma urea and creatinine levels increased and creatinine clearance decreased. Light microscopy revealed in CDs enlarged glomeruli with increased mesangial matrix and thickening of the glomerular capillary wall; electron microscopy demonstrated thickened basement membrane and mesangial abundance. There was increased staining for type IV collagen in glomeruli and interstitium of CDs. The retinas of diabetic CDs demonstrated pathology consistent with nonproliferative diabetic retinopathy. The histological findings in the kidneys, the absence of proteinuria, the impairment in glomerular filtration, and the development of retinopathy in CDs are consistent with diabetes-associated nephropathy that is similar to a nonalbuminuric type of nephropathy associated with type 2 diabetes in humans.

Fifty type 2 diabetes patients (25 of them being hypertensive) who had no cardiac symptoms had their left ventricular function assessed. There were 24 female and 26 male diabetes patients evaluated, along with a control group of 50 healthy subjects. The patients and controls underwent full clinical evaluation, which included physical examination, blood biochemistry (urea and electrolyte; creatinine, creatinine clearance; fasting blood and two-hour postprandial glucose levels, lipid profile), electrocardiograph, chest radiograph, and echocardiograph. The hypertensive diabetes patients had higher cholesterol levels, and 50% had levels >5.0 mmol/L. Sixteen patients had cataracts, 14 had background retinopathy, 12 had peripheral neuropathy, and 7 had peripheral vascular disease. The subjects had significantly lower ejection fraction than controls, and fractional shortening showed a similar pattern. Eight patients had ejection fraction <50% compared to none of the controls. Sixty-six percent of the subjects and 30% of the controls had diastolic dysfunction (reverse E/A ratio, prolonged deceleration time, and lower deceleration rate), respectively, but the diabetes patients did not show any difference. Diastolic dysfunction correlated significantly with age, fasting blood glucose, and two-hour postprandial glucose. The subjects had higher left ventricular mass (LVM) than controls. The LVM correlated significantly positively with diastolic blood pressure, systolic blood pressure, and pulse pressure. Subclinical diabetic cardiomyopathy exists in our patients; in addition, other risk factors for cardiomyopathy and coronary artery disease exist, including hypertension, hypercholesterolemia, and obesity.

We recently reported that in subjects with untreated type 2 diabetes mellitus, a 5-week diet of 20:30:50 carbohydrate-protein-fat ratio resulted in a dramatic decrease in 24-hour integrated glucose and total glycohemoglobin compared with a control diet of 55:15:30. Body weight, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and serum ketones were unchanged; insulin and nonesterified fatty acids were decreased. We now present data on other hormones and metabolites considered to be affected by dietary macronutrient changes. The test diet resulted in an elevated fasting plasma total insulin-like growth factor 1, but not growth hormone. Urinary aldosterone was unchanged; free cortisol was increased, although not statistically. Urinary pH and calcium were unchanged. Blood pressure, creatinine clearance, serum vitamin B12, folate, homocysteine, thyroid hormones, and uric acid were unchanged. Serum creatinine was modestly increased. Plasma alpha-amino nitrogen and urea nitrogen were increased. Urea production rate was increased such that a new steady state was present. The calculated urea production rate accounted for 87% of protein ingested on the control diet, but only 67% on the test diet, suggesting net nitrogen retention on the latter. The lack of negative effects, improved glucose control, and a positive nitrogen balance suggest beneficial effects for subjects with type 2 diabetes mellitus at risk for loss of lean body mass.

We report on a patient whose type 2 diabetes mellitus resolved during IFN-alpha therapy for hepatitis C virus (HCV). A 40-year-old man was diagnosed with type II diabetes in year 2000. His body mass index (BMI) was 30.8 kg/m and glycosylated haemoglobin (HbA1c) was 10.7%. He was treated with metformin. Later, his glycaemic control deteriorated despite additional dietary and lifestyle advice and the addition of glibenclamide. He was started on subcutaneous insulin in 2002 with the continuation of metformin. In 2003 he was diagnosed with chronic hepatitis caused by HCV. In September 2003 he was started on IFN-alpha and ribavirin. After 24 weeks of treatment his HCV polymerase chain reaction remained positive and treatment was stopped as per guidelines. At the commencement of antiviral therapy, HbA1c was 7.7%. In April 2004 his BMI of 29.38 kg/m had reduced and he then stopped insulin therapy because of repeated hypoglycaemia. After stopping insulin his HbA1c was 4.7%. Fasting plasma glucose of 6.2 mmol/l and anti-glutamic acid decarboxylase antibodies were negative. Urea and creatinine levels were normal. Most of the earlier literature describes diabetes developing in the course of IFN-alpha therapy for a variety of diseases. More recent research has described a relationship between hepatitis C infection and the development of diabetes and insulin resistance. Responders to IFN-alpha treatment manifest an improvement in insulin sensitivity compared with non-responders after the completion of IFN-alpha therapy. Our case shows the resolution of pre-existing diabetes in a patient with chronic HCV infection, which did not respond to IFN-alpha therapy. Whether this occurred as a direct result of IFN-alpha on insulin sensitivity or indirectly as a result of weight loss because the therapy for HCV precipitated additional lifestyle changes in the patient is as yet unclear.

Ghrelin is a novel gut-brain peptide, which exerts somatotropic, orexigenic, and adipogenic effects. Genetic variants of ghrelin have been associated with both obesity and insulin metabolism. In this study, we determined a role of preproghrelin Leu72Met polymorphism on type 2 diabetes mellitus and its relationship to variables studied. Genotypes were assessed by polymerase chain reaction. Frequencies of the Leu72Met polymorphism were found to be 35.4% in the type 2 diabetic patients and 32.5% in the normal controls. The Leu72Met polymorphism was not associated with hypertension, macroangiopathy, retinopathy, serum cholesterol, triglyceride, blood urea nitrogen, HbA(1c), lipoprotein (a), fasting insulin, or 24-hour urinary protein levels in the type 2 diabetic group. However, the Leu72Met polymorphism was clearly associated with serum creatinine levels in the diabetic group, as the Met72 carriers exhibited lower serum creatinine levels than the Met72 noncarriers. Our data indicate that the preproghrelin Leu72Met polymorphism is not associated with type 2 diabetes mellitus. However, the Leu72Met polymorphism is associated with serum creatinine levels. These data suggest that Met72 carrier status may be a predictable marker for diabetic nephropathy or renal impairment in type 2 diabetes mellitus.
