Of the many information obtainable from the urine of diabetic patients, urinary C-peptide (CPR), albumin and anti-diuretic hormone (ADH) were representatively described using my clinical and experimental data. C-peptide excretion in 24h collection of urine is a good estimate of insulin secretion from the pancreas and thus low in IDDM patients and even in NIDDM patients at a later stage, but high in pathological conditions including Graves' disease, obesity, liver cirrhosis and Cushing's syndrome. Urinary albumin excretion in small amounts (microalbuminuria) is usually observed in diabetic patients who have been under a poor control state of diabetic hyperglycemia for over 5 years and provides a good tool for monitoring early diabetic nephropathy. The grade of microalbuminuria (30-300 mg/day) is positively correlated with the HbA1 level in diabetic patients, showing that microalbuminuria is reversible along with an improvement of diabetic control at least in an early phase of diabetic nephropathy. As the albumin level measured in a spot urine sample correlates well with the value in the 24h collection of urine, the albumin measurement is conveniently feasible with a spot urine sample at every patient's visit. The amount of ADH excreted in urine is 7-10% of that secreted from the posterior pituitary. The excretion of ADH in a day was in the urine of diabetic patients positively correlated with HbA1, urinary osmolarity and concentration of sodium in urine, although the pathological meaning of the observed ADH hypersecretion in the development of diabetic complications is currently unknown.

We have investigated the influence of variation of the concentrations of serum albumin and immunoglobulins on serum fructosamine concentration in 33 patients with nephrotic syndrome, and 18 patients with cirrhosis of the liver. Protein alterations were evident in these patients and they were compared with 109 normal subjects, 43 patients with type II diabetes mellitus and nine diabetic patients with nephrotic syndrome. The mean serum fructosamine concentration in diabetic patients (2.76 +/- 0.53 mmol/L) was significantly increased (P less than 0.001) by comparison with normal subjects (1.93 +/- 0.20 mmol/L) and the other patients studied. Patients with diabetic nephropathy had higher (P less than 0.01) serum fructosamine concentrations (2.23 +/- 0.54 mmol/L) than non-diabetic patients with the nephrotic syndrome (1.57 +/- 0.37 mmol/L) but remained with the normal range. Positive correlations were observed between fructosamine and immunoglobulins G and M in nephrotic and cirrhotic patients. Serum immunoglobulin A was also directly correlated with serum fructosamine in patients with cirrhosis of the liver. An inverse correlation between albumin and fructosamine in serum of patients with cirrhosis of the liver was also noted. We conclude that the fructosamine assay is not useful in the assessment of glycemic control in patients with cirrhosis of the liver, nephrotic syndrome or in any other clinical situation in which protein metabolism is altered.

A patient with cirrhosis and coexistent hyporeninemic hypoaldosteronism secondary to diabetic nephropathy rapidly formed ascites despite marked reductions in plasma aldosterone concentration and urinary aldosterone excretion. To my knowledge, this association has not been previously reported. This case supports the concept that hyperaldosteronism is not a necessary component of the salt retention of advanced liver disease. Furthermore, it suggests that certain renal disorders should be considered in cases of cirrhosis and ascites with decreased plasma renin activity.

The present study evaluated end-stage renal disease (ESRD) patient survival in Lombardy, Italy, and the United States (U.S.) using data from two registries, the Lombardy Dialysis and Transplant Registry (RLDT) and the U.S. Renal Data System (USRDS), respectively. For this purpose, 4,196 white patients (2,900 from the USRDS Case Mix Severity Study and all 1296 from RLDT) who started renal replacement therapy in 1986 and 1987 were studied. Compared to Lombardy patients, those in the USA were significantly older (mean age 59.9 +/- 16.4 vs. 55.9 +/- 14.7 years), had a lower proportion of males (53.7 vs. 62.1%), a greater proportion with diabetic nephropathy (29.9 vs. 9.7%) and a significantly greater proportion of patients with the recorded comorbid conditions (heart disease, peripheral vascular disease, cirrhosis, cachexia, malignancy). U.S. patients were less frequently treated with peritoneal dialysis (PD) by day 30 of ESRD (21.2 vs. 30.7). Survival was compared in the Cox proportional hazard regression model, using age, sex, comorbid conditions and early modality of treatment as explanatory covariates. Overall, 48% of the 4196 patients died during the 48 to 72 months follow-up to 12/31/91. Per 100 patient-years the gross death rate for USRDS patients was 28.7 compared to 13.0 of RLDT patients. The unadjusted death relative risk for RLDT was 0.439, that is, 56% lower death rate compared to USRDS patients. Age, sex, diabetic status, each of the recorded comorbid conditions and treatment modality were significantly related to survival and included in the model. The Cox cumulative survival adjusted for all these explanatory covariates survival was for U.S. patients 84.4% at one year, 67.0% at two years and 33.4% at five years, and for RLDT patients 88.3% at one year, 75.9% at two years and 45.9% at five years. The relative mortality risk (RR) for the patients treated in Lombardy adjusted for all the reported covariates was 29% lower than for US patients (RR = 0.71; P < 0.0001). This comparative risk varied significantly by age (P < 0.0001) and was 65 percent lower for Lombardy compared to U.S. patients in the age range 25 to 44 years (RR = 0.35) and about 20% lower for patients over age 65 years (RR = 0.80). This relative risk was mainly related to hemodialysis and was not statistically significant for PD patients. The observed lower mortality risk in Lombardy was less pronounced when adjusted for demographic and comorbid covariates, but was still large and therefore suggests the need for further studies regarding treatment related factors and unmeasured patient factors, particularly in hemodialysis patients.

Hepatitis C viral infection occurs relatively low in Korea compared to hepatitis B. However, it progresses into chronic hepatitis and cirrhosis more frequently than HBV. It may be associated with cryoglobulinemia and glomerulonephritis, both in native and transplanted kidneys. We report three cases of membrano-proliferative glomerulonephritis type I in anti-HCV positive, but cryoglobulin-negative patients, presenting massive proteinuria, two in native kidneys and one in an allograft. HCV-RNA was positive in sera of two patients. Two were cirrhotic and ALT was mildly elevated in two. In addition to the characteristic membranoproliferative feature, two native kidneys overlapped with features of diabetic nephropathy. Immunofluorescence demonstrated mainly IgM and C3 deposits along the peripheral capillary walls. Subendothelial electron dense deposits were present in the glomeruli of all three cases with subepithelial and intramembranous deposits in two. HCV-RNA was associated not only with a greater amount of immune deposits but also with subepithelial and intramembranous deposits, indicating the role of active infection.

Organ transplantation and subsequent therapeutic agents may induce or worsen preexisting diabetes mellitus. We report the case of a diabetic patient whose insulin needs disappeared after liver transplantation. Non insulin-dependent diabetes mellitus was diagnosed when she was 47, and was treated by hypoglycemic drugs and then insulin. Chronic post-hepatitis C cirrhosis was diagnosed at the age of 55 and required liver transplantation 2 years later. During the postoperative course, the insulin doses required to maintain normal glucose levels progressively decreased, and insulin became completely unnecessary by the 29(th) postoperative day. After insulin was stopped, glucose levels remained within normal ranges for the 5-year-long follow-up, despite the worsening of a preexisting diabetic nephropathy and the occurrence of a diabetic retinopathy. This case highlights the fact that liver transplantation may eliminate insulin needs in a diabetic patient but also shows that degenerative complications may occur despite apparent remission of diabetes.

SR121463 is a selective, orally active, non-peptide antagonist of vasopressin (AVP) V(2) receptors with powerful aquaretic properties in various animal species and humans. SR121463 belongs to a new class of drugs, called aquaretics, which are capable of inducing free-water excretion without affecting electrolyte balance. SR121463 displays high affinity for animal and human V(2) receptors and exhibits a remarkably selective V(2) receptor profile. SR121463 and [(3)H]SR121463 are used, therefore, as selective probes for characterization and labeling of V(2) receptors. In various functional studies in vitro, SR121463 behaves as a potent antagonist. It inhibits AVP-stimulated human renal adenylyl cyclase and dDAVP (1-desamino, 8-D arginine-vasopressin)-induced relaxation of rat aorta. SR121463 also behaves as an inverse agonist in cells expressing a constitutively activated human V(2) receptor mutant. In vitro, SR121463 rescued misfolded V(2) AVP receptor mutants by increasing cell surface expression and restoring V(2) function. In normally hydrated conscious rats, dogs and monkeys, SR121463, by either i.v. or p.o. administration, induced a dose-dependent aquaresis with no major changes in urinary Na+ and K+ excretion (unlike classical diuretics). In cirrhotic rats with ascites and impaired renal function, a 10-day treatment with SR121463 totally corrected hyponatremia and restored normal urine excretion. In a model of diabetic nephropathy in rats, SR121463 strongly reduced albumin excretion. SR121463 was also effective at extrarenal V(2) (or V(2)-like) receptors involved in vascular relaxation or clotting factor release in vitro and in vivo. In the rabbit model of ocular hypertension, SR121463 by either single or repeated instillation, decreased intraocular pressure. After acute and chronic administration to rats, dogs or healthy human volunteers, SR121463 was well absorbed and well tolerated. In all species studied the drug produced pronounced aquaresis without any agonist effect. Thus, SR121463 is a potent, orally active and selective antagonist at V(2) receptors with powerful aquaretic properties. It is a useful tool for further exploration of function of renal or extrarenal V(2) receptors. Pure V(2) receptor antagonists are likely to be therapeutically useful in several water-retaining diseases such as hyponatremia, Syndrome of Inappropriate Antidiuretic Hormone secretion (SIADH), congestive heart failure, liver cirrhosis, and other disorders possibly mediated by V(2) receptors (e.g., glaucoma).

The annual statistical survey conducted at the end of 2000 by the Japanese Society for Dialysis Therapy collected responses from 3358 (99.94%) of 3360 institutions. Japan's total dialysis patient population at the end of the year 2000, as identified by this survey, was 206,134, an increase of 8921 (4.5%) over 1999. This translates to 1624.1 patients per million population. The annual crude mortality rate was 9.4% for the period starting at the end of the year 1999 and ending at the end of the year 2000. The mean patient age at the initiation of dialysis treatment was 63.8 (+/- 13.9; +/- SD) years; the mean age of the overall dialysis patient population was 61.2 years (+/- 13.3). Both these mean ages, which had been increasing since 1983, again continued to increase. Among the primary diagnosis, the prevalence of diabetic nephropathy had continued to increase again since 1999, to 36.6%, whereas that of chronic glomerulonephritis had continued to decline, down to 32.5%, during the same one-year period since the 1999 survey. The 2000 years-end survey incorporated the following additional variables for the first time: usage of oral antihypertensives, pre- and post-dialysis systolic and diastolic blood pressures, serum HDL cholesterol level, types and dosage of oral Vitamin D analogs administered, dosage of oral calcium carbonate administered, history of intervention for peripheral vascular disease (bypass surgery, synthetic graft replacement, stenting), history of coronary artery bypass grafting (CABG), history of percutaneous transluminal coronary angioplasty (PTCA), whether stenting had been previously performed for the treatment of ischemic heart disease, number of cigarettes smoked, the type of vascular access used at the initiation of dialysis, and the year and month the vascular access was created. The survey results indicate that 60.9% of the total dialysis patient population was using oral antihypertensives. The patients' mean serum HDL cholesterol level was 47.65 +/- 18.47 mg/dL, showing positive correlation with serum albumin level and reverse correlation with body mass index. 1.6% of all dialysis patients had previously undergone amputation, and 0.7% had a history of bypass surgery for peripheral vascular disorder. 4.5% of hemodialysis patients had a history of cardiac infarction, 1.6% had previously undergone CABG, and 2.8%, PTCA. At the time the survey was conducted, 2.0% of all dialysis patients were undergoing oral Vitamin D analog pulse therapy, and 6% were undergoing intravenous Vitamin D analog pulse therapy. A history of amputation, myocardial infarction, cerebral infarction, and cerebral bleeding were identified as high-risk factors of vital prognosis. Additionally, high mortality risk was associated with the following: glutamic-pyruvic transaminase levels exceeding 20 IU/L; positive HCV antibody status; comorbid conditions such as hepatic cell carcinoma and liver cirrhosis; platelet counts below 100,000/mL or equal to or greater than 200,000/mL; C-reactive protein levels of 0.2 mg/dL and higher, leukocyte counts of less than 3000/mL or equal to or greater than 8000/mL; and body mass index of below 22 kg/m2, as well as total serum cholesterol levels of below 160 mg/dL or equal to or greater than 260 mg/dL.

Although most cellular glutathione (GSH) is in the cytoplasm, a distinctly regulated pool is present in mitochondria. Inasmuch as GSH synthesis is primarily restricted to the cytoplasm, the mitochondrial pool must derive from transport of cytoplasmic GSH across the mitochondrial inner membrane. Early studies in liver mitochondria primarily focused on the relationship between GSH status and membrane permeability and energetics. Because GSH is an anion at physiological pH, this suggested that some of the organic anion carriers present in the inner membrane could function in GSH transport. Indeed, studies by Lash and colleagues in isolated mitochondria from rat kidney showed that most of the transport (>80%) in that tissue could be accounted for by function of the dicarboxylate carrier (DIC, Slc25a10) and the oxoglutarate carrier (OGC, Slc25a11), which mediate electroneutral exchange of dicarboxylates for inorganic phosphate and 2-oxoglutarate for other dicarboxylates, respectively. The identity and function of specific carrier proteins in other tissues is less certain, although the OGC is expressed in heart, liver, and brain and the DIC is expressed in liver and kidney. An additional carrier that transports 2-oxoglutarate, the oxodicarboxylate or oxoadipate carrier (ODC; Slc25a21), has been described in rat and human liver and its expression has a wide tissue distribution, although its potential function in GSH transport has not been investigated. Overexpression of the cDNA for the DIC and OGC in a renal proximal tubule-derived cell line, NRK-52E cells, showed that enhanced carrier expression and activity protects against oxidative stress and chemically induced apoptosis. This has implications for development of novel therapeutic approaches for treatment of human diseases and pathological states. Several conditions, such as alcoholic liver disease, cirrhosis or other chronic biliary obstructive diseases, and diabetic nephropathy, are associated with depletion or oxidation of the mitochondrial GSH pool in liver or kidney.

A 64-year-old man was admitted because of abdominal fullness, edema and anorexia. He had come to our hospital for treatment of liver cirrhosis and diabetic nephropathy for 1 year. We started diuretics and human albumin intravenous administration. Although the edema disappeared and abdominal fullness improved a little, blood urea nitrogen (BUN) and serum creatinine became elevated, hepatic function deteriorated and he lost his appetite. We consequently started continuous ambulatory peritoneal dialysis (CAPD) in order to control ascites and uremia. Abdominal fullness, appetite and BUN and serum creatinine improved without hepatic function deterioration. It might be important to start CAPD to control ascites although serum creatinine levels might be slightly elevated.
