Serum erythropoietin (EPO) levels were determined by the recombigen EPO RIA kit (DPC) in normal subjects and patients with renal dysfunction, diabetes mellitus, hypothyroidism and a variety of hematological disorders. Mean (+/- SD) serum EPO levels were 18.6 +/- 5.6 mU/ml in 180 normal subjects and no sex difference was obtained. Serum EPO levels in older subjects were slightly greater than those in younger subjects. There was a negative correlation between serum EPO levels and Ht values in anemic patients with normal renal function, whereas serum EPO levels were within the normal range in anemic patients with renal disorders, suggesting that serum EPO levels were relatively low in patients with chronic renal failure. Serum EPO levels were rather increased in patients with diabetes mellitus and hypothyroidism. High serum EPO levels were obtained in patients with a variety of hematological disorders such as acute leukemia, multiple myeloma, myelodysplasia syndrome, aplastic anemia and pure red cell aplasia. In a patient with pure red cell aplasia treated with glucocorticoids, serum EPO levels were lowered before anemia was recovered and reticulocytes were increased. These findings indicate that measurement of serum EPO levels are useful for not only differential diagnosis of anemia but also clinical evaluation of the treatment.

We have used streptozotocin (STZ)-induced diabetes in rats to determine whether this represents a sustained stimulus to the adrenocortical system and whether STZ-diabetic rats are able to mount an acute stress response. Furthermore, we compared pituitary responsiveness to CRF and/or arginine vasopressin, and adrenal responsiveness to ACTH in STZ- vs. vehicle-treated rats. We also compared the efficacy of dexamethasone inhibitory feedback in STZ-diabetic and control rats. Our results show that STZ-treated rats chronically hypersecrete corticosterone (B) as evidenced by their decreased thymus weights, their increased urinary B excretion, and their elevated mean plasma B levels during the light hours of the day. Despite the evidence for sustained hypersecretion of B, STZ-treated rats showed greater and more prolonged ACTH and B responses to the acute stress of histamine injection. However, when tested separately, neither pituitary nor adrenal responsiveness to their secretagogues were increased in STZ-diabetic compared to control rats. Dexamethasone inhibition of stress-induced B secretion was tested using two different paradigms: pentobarbital-anesthetized rats were given iv injections of acid saline, and awake rats were given ip injections of histamine. In both experiments the STZ-treated rats were relatively resistant to glucocorticoid inhibition of stress responses. This finding, taken together with the exaggerated ACTH and B responses to stress, strongly suggests that the facilitatory effects of chronic STZ-diabetes are a consequence of changes in sensitivity of central neural components of the adrenocortical system to stimulatory and/or inhibitory inputs, in conjunction with changes in glucocorticoid feedback sensitivity.

To determine which members of the health care team are viewed by ESRD patients as the most helpful in giving information and deciding on a dialysis modality, we surveyed 42 outpatients after they toured the dialysis facility. The tour included discussions with a social worker, PD and HD nurses, watching a videotape, and receipt of written materials. Nephrologists referred patients for tours. Multiple responses were accepted. Patients felt that social workers (70%) and nurses (71%) gave the most useful information. Fifty per cent of patients thought the nurse, 43% the social worker, 21% the nephrologist, and 21% family or friend most helpful in deciding on PD versus HD. Twenty-three patients chose PD, 16 chose in-center HD. Patients choosing PD were more likely to be white (20/29 versus 3/10, p less than 0.05) and employed (11/23 versus 3/16 choosing HD, p less than 0.10). Patients choosing PD were also better educated but this was not independent of race. No differences in gender, age, or the presence of diabetes were seen among those choosing PD versus HD. Social workers and nurses are more influential than nephrologists in helping patients select a dialysis modality. PD patient recruitment efforts should focus on social workers' and nurses' input.

To evaluate patient survival among geriatric patients by dialytic treatment of choice we assigned all patients aged 65 years and older treated in Michigan to either CAPD at home or center hemodialysis (HD) according to the treatment used on day 120 of ESRD therapy. Michigan Kidney Registry files on all 308 CAPD and 1244 HD patients who started ESRD therapy during 1980-1987 were used for this study. The Cox proportional hazards model revealed a significantly increased relative death rate (RR) for patients with diabetes (RR = 1.91, p less than 0.001) and hypertension (RR 1.4, p less than 0.01) as cause of ESRD when adjusting for age, sex, race, treatment and year of incidence. White patients had a 51% higher relative death rate overall when compared to black patients (p less than 0.001) and specifically among hypertensive (RR = 1.65, p less than 0.001) and diabetic patients (RR = 1.59, p less than 0.001). Those differences were still significant when taking higher rates of withdrawal from dialysis among white patients into account. The relative death rates for CAPD patients was essentially the same as for HD patients overall, however, diabetic CAPD patients appeared to have a higher than diabetic HD patients (RR = 1.58, p = 0.1). This statistically not significant difference may be related to selection of patients with cardiovascular risk into CAPD. There was no trend in mortality over time. By modality on day 120, CAPD has similar outcomes as HD in geriatric non diabetic patients.

We investigated by enzyme electrophoresis after prolonged neuraminidase treatment the activity of "intestinal variant" (alpha 2-globulin mobility) alkaline phosphatase (EC 3.1.3.1; ALP) in the plasma of 189 patients selected for disorders (diabetes mellitus, liver cirrhosis, and chronic renal failure) with a known high frequency of increased plasma intestinal (beta-globulin mobility) ALP activity. The overall frequency of the variant ALP was 23.8%, whereas in the samples showing intestinal ALP it was 45.0%. The variant ALP was not observed in the absence of intestinal ALP, nor in patients of blood group A. Its frequency did not differ significantly between the different patient groups. Quantification of the variant ALP by densitometry was unsatisfactory but the quantity could be estimated by subtracting the intestinal ALP activity measured by electrophoresis from the activity determined by immunoassay with monoclonal antibody that reacts with both the intestinal and the variant forms. This indicated median activity of 12 U/L for the variant, approximately equal to that of the concomitant intestinal ALP. From the effects of papain and bromelain treatments, we suggest that "intestinal variant" represents intestinal ALP with attached membrane-binding domain.

There is an excess incidence of ESRD treatment among non-White North Americans that is not completely explained by the racial prevalences of the underlying diseases, including hypertension, which can potentially cause renal disease. The racial difference is particularly striking for presumed nephrosclerosis from hypertension and for nephropathy from Type II diabetes, but is not yet substantiated for ESRD attributed to polycystic kidney disease or Type I diabetes. The existing data are insufficient to support the notion that poorer blood pressure control alone is responsible for the racial differences in incident ESRD. Black race (and possibly Mexican or Native American heritage) may be a specific risk factor for ESRD, independent of hypertension and its treatment.

We report here a case of penile gangrene in a patient with diabetic nephropathy treated by continuous ambulatory peritoneal dialysis (CAPD). The patient demonstrated severe systemic arteriosclerosis. The main cause of the gangrene was considered to be circulatory insufficiency induced by severe arteriosclerosis. Several predisposing factors including chronic renal failure, long-term diabetes mellitus and CAPD-related metabolic changes such as abnormalities of lipid metabolism also appeared to have contributed to the arteriosclerotic changes. The prognosis in cases of this type is thought to be extremely poor.

1. Graft survival rates increased about 3-5 percentage points for patients with all primary diseases in 1989-1990. 2. Patients with different diseases had 1-year graft survival rates that varied from 73% for noninsulin-dependent diabetes (NIDDM) to 83% for IgA nephropathy (IgAN). Five-year graft survival varied from 40% for NIDDM to 66% for IgAN. 3. Our findings in Clinical Transplants 1990 that IgAN patients have a high graft survival was confirmed and 1-year graft survival improved by 5% in the last 2 years. 4. There was a 20 percentage point increase in full-time work status of patients after transplantation; 68% of patients with polycystic kidney disease (PKD) and chronic glomerulonephritis (CGN) had full-time work status after 3 years whereas patients with diabetes mellitus (DM) and atheronephrosclerosis (NS) had about 50%. 5. Good early graft function (urine output during the first 24 hours posttransplant, no dialysis within the first-week posttransplant, and no rejection episodes before discharge), predicted good 1-year graft survival for patients with different diseases but patients with NS and DM had a poorer graft survival beyond the first year posttransplant. Patients who had poor early function had 20% lower graft survival than those who had good function. However, in patients with IgAN, no urine at day 1 still resulted in graft survival comparable to those that produced urine. 6. More patients with DM were transplanted within 1 year after going into ESRD than those with other diseases. Conversely, 46% of those with NS did not get transplanted until more than 2 years after developing ESRD. 7. Only 77% of NS patients had functioning grafts at discharge compared to DM (84%), PKD (81%), IgAN (81%), and CGN (80%). 8. Black patients had a statistically significant higher incidence of anuria on the first day compared with Whites. They also had a higher incidence of dialysis and rejection during the first hospitalization. This was true for CGN, DM, PKD, and NS patients. Following excellent early function, Black CGN and DM patients had a higher incidence of rejection than White CGN and DM patients.

Until recently Type 1 diabetes has been characterized by a considerable degree of mortality, mainly associated with the development of diabetic nephropathy. Diabetic nephropathy is characterized by persistent proteinuria, decreasing glomerular filtration rate (GFR), increasing blood pressure, and morphological changes. Proteinuria represents a late stage in a prolonged process, which begins at the onset of Type 1 diabetes, when urinary albumin excretion is at the lower end of its normal range (less than 10 mg 24-h-1). However, in those patients who will later develop persistent proteinuria, urinary albumin excretion increases exponentially at about 20% per year. These patients also tend to have rising blood pressure and falling GFR, higher rates of proliferative retinopathy and coronary heart disease, and elevated levels of cardiovascular risk factors. As intervention is possible in all these areas, identification of such patients is required and especially as the imposition of strict metabolic control may postpone or arrest progression to overt nephropathy. Where patients deteriorate despite such control the institution of early antihypertensive therapy and the effective management of end stage renal disease will bring further improvements in the prognosis of diabetic nephropathy.

We report cases of angina pectoris or minimal acute myocardial infarction accompanied by pulmonary edema, which were retrospectively studied with regard to their clinical characteristics, prognosis and treatment. Sixteen patients, 5 males and 11 females with a mean age of 72.6 years, admitted to the Cardiovascular Center of Sendai between January 1986 and June 1989, were studied. Ten had previous myocardial infarction. Hypertension, chronic renal failure and diabetes mellitus were found in 10, 7 and 7 patients, respectively. Electrocardiograms during cardiac ischemic attacks showed ST elevation in 8 and ST depression in the other 8 patients. Coronary arteriography which was performed in 6 patients revealed three-vessel disease in 5, and two-vessel disease in one. Mechanical ventilation was indicative of 7, and intraaortic balloon counterpulsation in 2 patients. Coronary artery bypass graft surgery was performed for 3 patients. All patients recovered from pulmonary edema and were discharged. During the mean 15-month-follow-up period, 8 patients died. The causes of death were sudden cardiac death in 3, acute myocardial infarction in one, congestive heart failure in one, post-surgical death in one, and non-cardiac death in 2.
