We measured circulating concentrations of endothelin, a recently discovered vasoconstrictor peptide produced by vascular endothelial cells, in healthy subjects and in patients with abnormal vascular reactivity. Endothelin concentrations were determined by radio-immunoassay after extraction of plasma using Sep-Pak C-18 cartridges in healthy subjects (n = 20), in patients with diabetes mellitus type I (n = 10), in patients with mild to moderate essential hypertension (n = 12) and in non-dialyzed patients with stable chronic renal failure (n = 12). Plasma concentrations were similar in healthy controls, in diabetics and in hypertensive patients averaging 5.0 +/- 0.6 pg/ml, 4.7 +/- 0.2 pg/ml and 6.5 +/- 1.0 pg/ml, respectively. In contrast, plasma concentrations of endothelin were markedly elevated in patients with chronic renal failure averaging 16.6 +/- 2.9 pg/ml (p less than 0.005). No correlations were observed between serum creatinine concentrations ranging from 124 to 850 mumol/l or blood pressure and plasma concentrations of endothelin. Bicycle ergometric exercise in six healthy subjects and an acute modest i.v. saline load of 1,000 ml of 0.45% NaCl administered within 60 min in six patients with mild essential hypertension did not affect plasma concentrations of endothelin. Thus, it is unlikely that vascular synthesis of endothelin is related to acute physiological changes in systemic hemodynamics or to the circulatory and renal responses to acute extracellular fluid volume (ECFV) expansion. A potential role of endothelin, however, in the control of regional blood flow cannot be excluded. Elevated plasma concentrations of endothelin observed in patients with chronic renal failure require further investigations.

Peritoneal function is the major determinant of the efficiency of peritoneal dialysis. To understand whether diabetes affects the peritoneal function, we performed the peritoneal clearance study in 9 diabetic and 16 nondiabetic patients with end stage renal disease. The ultrafiltration volume tended to be lower in diabetics after infusion of 1.5% Dianeal, although there were no statistically significant differences between them. The same results were obtained after infusion of 4.25% Dianeal. The glucose uptake after infusion of both 1.5% and 4.25% Dianeal was not significantly different between the two groups. The dialysate/plasma(D/P) concentration ratio was also not significantly different between the two groups, however the D/P ratio for BUN and uric acid was slightly higher in the diabetic group. The peritoneal clearance of smaller molecules such as BUN, creatinine, uric acid and phosphate also tended to be higher in diabetics after infusion of 1.5% Dianeal for 4 hours. The peritoneal clearance became higher when more hyperosmotic dialysate were used in both diabetics and nondiabetics. The above results indicated that diabetic patients with end stage renal disease might have a normal peritoneal function compared to nondiabetics.

1. To assess the risk of end-stage renal disease (ESRD) associated with the regular use of three classes of non-narcotic analgesics, we performed a case-control study of 340 patients with ESRD on a haemodialysis maintenance program and 673 hospital controls. 2. The overall odds ratio estimate for non-narcotic analgesics taken at least every other day for 30 days or longer before the first symptom of renal disease was 2.89 (95% CI, 1.78 to 4.68). 3. The risk increased in relation to the use duration. 4. The previous regular consumption of combinations containing phenacetin was strongly associated with ESRD (odds ratio, 19.05; 95% CI, 2.31 to 157.4). The odds ratio for previous regular consumption of salicylates was 2.54 (95% CI, 1.24 to 5.20) and for pyrazolones 2.16 (95% CI, 0.87 to 5.32). 5. An analysis for possible confounding by a history of repeated headaches, arthritis, kidney stones, hypertension, and diabetes did not alter the results. 6. The odds ratio estimates for different pathological subgroups of ESRD patients in relation to previous use of any non-narcotic analgesic were glomerulonephritis. 10.57 (95% CI, 1.25 to 89.0), interstitial nephritis, 3.33 (95% CI, 1.21 to 9.17), cystic kidney disease, 0.71 (95% CI, 0.25 to 1.97), and unknown, 5.15 (95% CI, 2.29-11.57). 7. The results of this study suggest that the regular consumption of analgesics should be routinely considered as a risk factor for any non-congenital cause of chronic renal failure. They also suggest that the risk of ESRD associated with the regular consumption of phenacetin is much higher than the risk associated with other non-narcotic analgesics.

Melioidosis, a severe, often fatal disease caused by infection with Pseudomonas pseudomallei, has been thought to be a rare endemic disease relatively limited to the areas 20 degrees on either side of the equator. However, an increasing number of people travelling to these areas are reportedly suffering from this disease. It is timely to review this disease for doctors who are unfamiliar with this disease. P. pseudomallei, first discovered by Whitmore and Krishnaswami in 1912, is a gram-negative aerobic rod, motile due to polar flagella, isolated from soil and natural waters in endemic areas, and presumably transmitted to human beings through skin abrasion, ingestion and inhalation. Associated underlying conditions must be searched for, such as diabetes mellitus and chronic renal failure. Clinical classification ranges from disseminated septicemic melioidosis, the most serious form, to subclinical melioidosis, the least serious form. Disseminated septicemic type is associated with high fever, multiple organ lesions with septic shock and high fatality rate within a few days after symptoms develop. This type of infection requires prompt institution of antimicrobial therapy as well as surgical intervention such as drainage. Antimicrobial agents should be carefully selected according to the susceptibility results of the isolates. During the suspected stage, ceftazidime is a drug of choice. Subclinical melioidosis associated with positive serologic test alone should be closely followed up against the potential reactivation of dormant infection with P. pseudomallei. We must certainly be aware of melioidosis and diagnose melioidosis as early as possible by completing the initial routine diagnostic procedures to febrile patients.

Renal transplantation is an accepted treatment for patients with end stage renal disease from insulin-dependent diabetes mellitus. Acute lumbosacral plexopathy developed following renal transplantation in 4 female patients with insulin-dependent diabetes mellitus between January 1, 1981 and June 30, 1988. In all 4 patients the internal iliac artery was used for revascularization of the renal allograft with ligation of the anterior and posterior divisions. Within 24 hours of surgery they complained of ipsilateral buttock pain, numbness in the leg and weakness below the knee. This complication has not been observed in nondiabetic patients at our institution, nor in diabetic patients when the internal iliac artery was not used. However, lumbosacral plexopathy occurred in 4 of 27 (14.8%) female patients with insulin-dependent diabetes mellitus when the internal iliac artery was used (p less than 0.001). Age, duration of insulin-dependent diabetes mellitus, hypertension, cigarette smoking history and kidney donor were not significant predictors of this complication. This unusual and newly recognized complication appears to result from ischemia of the lumbosacral plexus following ligation of the internal iliac artery in patients with severe small vessel disease.

End-stage renal disease is a devastating complication of essential hypertension and type II diabetes mellitus, conditions that commonly occur together. We and others have previously suggested that the outcome of both conditions may be influenced by more aggressive treatment. We examined a large general medicine outpatient population; 72% were black and 41% were diabetic (95% type II). Decreased renal function, defined as a serum creatinine greater than or equal to mg/dL, developed in 18.1%. A multivariable logistic regression analysis identified glucose control, systolic blood pressure level, and male gender as indicators of decreased renal function. These data suggested that both glucose and blood pressure control may decrease the frequency of impaired renal function. However, when these variables were controlled, blacks still had almost twice the risk for renal dysfunction of whites. The data draw attention to, and elucidate the exceptionally high incidence of renal dysfunction in hypertensive blacks with or without diabetes. Further, they may explain the inordinate numbers of blacks with hypertension requiring dialysis. Prospective trials to test the efficacy of blood pressure and glucose control on the course of renal disease in hypertensive and/or type II diabetic patients are warranted.

Eighty patients with type I diabetes and end stage renal disease were prospectively evaluated for coronary artery disease with dipyridamole-thallium-201 scintigraphy and quantitative coronary angiography. Forty patients received dipyridamole orally, and 40 received it intravenously. The prevalence of coronary artery disease was 53%. There were no significant differences in the accuracy of the two dipyridamole tests (sensitivity = 85%, specificity = 85%, accuracy = 85% for the oral group; sensitivity = 86%, specificity = 72%, accuracy = 79% for the intravenous group). Combining the 80 patients into a single group gave a sensitivity of 86%, a specificity of 79%, and an accuracy of 83% for the detection of coronary disease. Although the accuracy of this test in this patient population was similar to that previously reported for other groups, the prevalence of disease was high and resulted in a low predictive value of a negative test (83%).

Fructosamine is thought to be an alternative diabetic long term parameter to HbAlc. A possible advantage of fructosamine is the shorter half life of this parameter. Therefore changes in the metabolic control of diabetes can be evaluated faster. However, daily variations of protein concentrations limit the clinical usefulness of fructosamine, especially in patients on hemodialysis, where we see variations in total protein- and albumin concentration during dialysis. Due to these limitations we studied the clinical usefulness of a new fructosamine assay in 38 patients with chronic renal failure. Fructosamine values, total protein, albumin, blood glucose and creatinine were measured before and after three hours hemodialysis treatment as well as glycosylated hemoglobin. Before dialysis HbA1c correlated with HbA1c after dialysis (r = 0.99), which documents the usefulness of glycosylated hemoglobin in patients on hemodialysis. Fructosamine before dialysis shows a correlation with fructosamine values after dialysis of r = 0.77. After correction with total protein the correlation was r = 0.95, also after correction with albumin. Fructosamine values before and after dialysis correlated excellently (r = 0.95). Fructosamine values before and after dialysis can only be compared after correction with total protein or with albumin.

We report on a 32-year-old female patient with chronic diabetes mellitus, type I, and chronic renal failure, who developed the typical clinical picture of hyperkeratosis follicularis et parafollicularis in cuteum penetrans (Kyrle's disease) within one year. Histological examination revealed a defective epidermal differentiation with hyper- and parakeratosis as well as premature keratinization as early as in the epidermal basal cell layer. Studies on lectin binding showed that the glycosylation process was impaired in both the epidermis and the basement membrane zone of the lesional skin. In addition, electron microscopic investigation revealed diabetic microangiopathy of the dermal vessels as well as marked ultrastructural alterations of the dermo-epidermal basal lamina. These findings confirm the association of diabetes mellitus with Kyrle's disease previously described; they make us suggest that Kyrle's disease might be characterized by a defective differentiation of the epidermis and the dermo-epidermal junction--due to some alteration of the underlying glycosylation processes--rather than by a local disorder of keratinization. Regarding the clinical manifestation of the disease, both diabetes mellitus and chronic renal failure may play a part as precipitating factors.

Autonomic nerve dysfunction in patients with chronic renal failure has of late become an issue to be investigated. R-R intervals in resting electrocardiograms were measured to evaluate activities of the cardiac parasympathetic nerve system. A total of 140 patients with chronic renal failure were studied to be compared with 20 normal controls (cont.) and 39 with diabetes mellitus (DM). Of these patients 15 were subjected to conservative treatment (CRF), while 125 patients were undergoing hemodialysis due to chronic renal failure-100 of them derived from chronic glomerulonephritis (HD) and 25 from diabetes mellitus (DM.HD). The variation coefficient of the R-R interval (CVRR) was measured after the subject patients had rested for over 15 minutes before a dialysis session. The mean CVRR were 2.15 +/- 1.25% in CRF group, 2.36 +/- 1.37% in HD and 1.37 +/- 0.99% in DM.HD. These values were significantly lower than in control group (4.70 +/- 2.64%). On the other hand, the value in DM.HD group, as shown above, was significantly lower than in HD. In CRF group the CVRR values lowered as residual renal functions decreased. No significant correlations between CVRR S and the duration of hemodialysis treatment were noted among the groups. In HD group the CVRR S were significantly lower in patients with hypotensive tendency during hemodialysis than in those who enjoyed good control of blood pressure. These results suggest that the measurement of CVRR S can be of help in evaluating autonomic nerve dysfunction in patients with chronic renal failure.
