Early experience with the treatment of patients with insulin-dependent diabetes and renal failure by chronic hemodialysis indicated a high mortality and increased incidence of medical complications. Since 1972, a marked improvement in survival and reduction in incidence of complications has been attributed to more rigorous control of fluid overload, hypertension, and blood sugar levels by insulin therapy and careful dietary management. A diet has been developed which combines the diet used by dialysis patients with suitable modifications for the insulin-dependent patient with diabetes. The importance of patient education is stressed in an attempt to improve patient compliance.

Forty-eight patients with acute renal failure (ARF) who were referred to the Department of Renal Medicine, Singapore General Hospital for acute dialysis between August 1985 and August 1989 were studied retrospectively to identify risk factors associated with ARF that serve as prognostic indicators. There was no difference in the mean age of survivors and non-survivors (49.5 +/- 17.5 years vs 53.5 +/- 18 years, p greater than 0.05). The overall mortality rate was 52%. ARF as a result of surgical complication had a higher mortality rate in comparison to ARF from medical complications (66% vs 50%, p greater than 0.05). Septicaemia was the most common cause of ARF requiring dialysis. Hepatobiliary sepsis was the most frequent cause of septicaemia. Pre-dialysis serum urea and creatinine levels, and the number of dialysis treatments did not affect the outcome. Poor prognostic indicators included oliguria or anuria, fluid overload and coma. Patients tended to have a worse outcome if they had more than three risk factors taken from the following list:-decreased renal perfusion, assisted ventilation, coma, gastrointestinal dysfunction, recent surgery, sepsis, congestive heart failure, hepatobiliary dysfunction, malignancy, diabetes mellitus, chronic renal insufficiency and poor nutritional status. Early referral of patients with septicaemia due in particular to hepatobiliary infection may improve the prognosis.

This paper synthesizes the pathogenic steps of arterial hypertension in diabetes mellitus: hyperosmolarity due to the hyperglycemia and increased sodic tubular reabsorption accounting for the expansion of the extracellular volume with hypervolemia; abnormalities of the ionic membrane pumps leading to abnormal intracellular calcium distribution, thereby inducing an increased vascular tone; atypical vasomotor reactivity to cathecolamines; modifications of the renin-angiotension-aldosterone system. The pathophysiological derangements by which hypertension could induce nephropathy are examined: the vasodilatation which can be detected from the onset of diabetes, may be a determinant in the transmission of systemic hypertension to the glomerular microcirculation with resulting enhancement of the hydrostatic transglomerular pressure gradient (i.c. the major factor producing glomerular injury), glomerular plasmatic flow and filtration rate. The nephron hyperfiltration increases the movement of plasmatic proteins across the glomerular capillary wall with subsequent mesangial hyperactivity and sclerosis. Antihypertensive treatment in diabetes follows general guidelines and it should be instituted even in the case of microhypertension being facilitated in this setting the appearance of microalbuminuria i.e. the starting point of nephropathy. Even if experimental studies are to favor ACE inhibitors as the first-line drugs for abating glomerular hypertension by mitigation of the direct effect of angiotensin II on the efferent arteriolar tone, clinical observations suggest that, regardless of type of treatment, the normalization of systemic arterial pressure, by reversing glomerular hypertension may be effective in preventing diabetic nephropathy.

The authors present a contemporary picture of the pathogenesis and clinical course of diabetic nephropathy in type I diabetics describing the stages of the disease and the possible evidence for reversibility of the kidney damage with tight metabolic control. During the so-called latency period, which is clinically non-detectable, the predominant functional abnormalities (increase in GFR with sub-clinical glomerular proteinuria) can be corrected by strict control although there is no evidence for the regression of the associated anatomical changes such as the enlarged filtration area. As for the described increase in thickness of the glomerular basement membrane, from experimental data and pancreatic transplants in man, delay in its development and to some extent regression of the glomerular lesions can be expected. The problem of how the renal lesions in experimental diabetes mirror the changes in the human kidney is discussed. During the symptomatic period, with intermittent and subsequently constant proteinuria and progressive decline in renal function, which are observed in only about 30% of type I diabetics, the role of arterial hypertension and its effective control is emphasized. Finally, the renal failure period is indicative of irreversible damage to the kidneys. The progression from its early to its late stages is variable between different patients but each individual patient shows a constant rate of deterioration. The evidence for the efficacy of medical treatment in slowing down its progression is very limited at present but much can be done to improve the quality of life by dietary measures, treatment of fluid overload and hypertension. When the end-stage diabetic kidney disease is reached, with serum creatinine above 8 mg/dl, renal transplantation from a living donor offers a good chance for a relatively acceptable quality of life for years. In conclusion, it is stressed that the morbidity of diabetic nephropathy could eventually be reduced through effective control of the metabolic abnormalities of diabetes with the methods presently available.

We report the occurrence of the adult respiratory distress syndrome (ARDS) in association with uncontrolled diabetes in nine patients. In reviewing the literature we found nine similar cases reported in little over a decade. In most cases no condition known to precipitate ARDS was discovered. The evidence suggests that the severely uncontrolled diabetic state in some way may initiate pathologic events leading to the capillary leak of ARDS. This description of the association of these two entities not commonly recognized as occurring simultaneously has important clinical implications: the entity should be anticipated in uncontrolled diabetic patients who present with acidosis, hypotension, hypothermia, and/or coma. The clinical or radiologic diagnosis of pneumonia or fluid overload should not be made in the uncontrolled diabetic patient in the absence of unequivocal evidence of infection or congestive heart failure. The development of dyspnea, hypoxemia, rales, or infiltrates in the otherwise routine resuscitation of these patients should lead the clinician to suspect the development of ARDS. Prompt invasive monitoring in these cases is indicated to aid in their management and may help to improve survival. We found calculation of the A-a gradient to be useful in patients with uncontrolled diabetes. Although not necessarily predictive, widened gradients were the earliest detectable abnormality found in all patients who developed ARDS.

Planning effective strategies of nutritional care for individuals with diabetic renal failure requires consideration of nutritional, social and medical factors. Typically, the diet is limited in protein, sodium, fluid potassium, and phosphorus content. Poor diabetes control in renal failure has been associated with fluid overload; elevated serum triglyceride levels; hyperkalemic episodes; and impaired protein synthesis. A diabetic meal plan, modified to meet the required nutrient restrictions, is, therefore, routinely developed for each individual. Serial monitoring of nutritional indexes in each patient enables early detection of nutritional wasting and is useful in evaluating the effectiveness of corrective dietary measures.

In this report, we present 2 cases of severe congestive heart failure and mild renal insufficiency in patients who underwent continuous ambulatory peritoneal dialysis (CAPD) after stabilization using the extracorporeal ultrafiltration method (ECUM). Long-term good control of congestive heart failure was achieved following the institution of CAPD. Case 1, a 58-year-old woman with rheumatic arthritis and diabetes mellitus had anteroseptal myocardial infarction at the age of 52. And case 2, a 68-year-old man, who underwent coronary artery bypass surgery at the age of 66 and had extensive anterior infarction after the operation. They were admitted to the hospital with dyspnea due to congestive heart failure. In both cases, systolic cardiac function was severely impaired and mild renal insufficiency was present at the time of hospitalization. After admission, symptomatic relief was not obtained by conventional therapies and symptoms of congestive heart failure worsened until the patients suffered from severe respiratory distress even at rest. ECUM was then instituted to remove excess fluid and clinical improvement was achieved. After the initiation of ECUM, responsiveness to diuretics was not restored, and the procedure was necessary every day or every other day for the prevention of symptoms due to fluid overload. About 20 days after the initiation of ECUM, CAPD was begun for the long-term control of congestive heart failure and renal failure, and for the purpose of hospital discharge. Good control of heart failure was achieved after the initiation of CAPD.(ABSTRACT TRUNCATED AT 250 WORDS)

The usefulness of plasma atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), C-type natriuretic peptide (CNP), and cyclic guanosine 3',5'- monophosphate (cGMP) as markers of fluid overload was examined in hemodialysis (HD) patients without diabetes mellitus. Plasma concentrations of ANP, BNP, CNP, and cGMP all decreased significantly during HD. Before HD, there was a strong correlation between plasma concentrations of ANP and those of BNP, and plasma concentrations of cGMP correlated significantly with those of all three natriuretic peptides. The cardiothoracic ratio also correlated significantly with plasma concentrations of ANP and those of BNP before HD. Systolic blood pressure correlated significantly only with plasma concentrations of CNP, both before and after HD. Changes in body weight during HD correlated only with those in plasma ANP; there was thus no correlation between changes in body weight and those in plasma CNP. In conclusion, only plasma ANP is a useful marker of the proper volume and dry weight of HD patients. Furthermore, CNP may participate in cardiovascular regulation in HD patients in a manner different from those of ANP and BNP.

The aetiology, biochemistry, clinical features and complications of histologically confirmed hepatic cirrhosis in 45 patients (26 females, 19 males) seen at the University Hospital of the West Indies, Jamaica, between 1984 and 1994 are presented. The age range was 1 to 72 years (mean 48 years). Abdominal swelling and weight loss were the commonest symptoms, occurring in 51% and 47% of patients, respectively. Jaundice was a presenting feature in 44%. Hepatomegaly was present in 71% of patients and splenomegaly in 33%. The aetiological factors were: alcohol (36%), bush tea (18%), chronic active hepatitis (11%), drugs (7%), and haemochromatosis (2%). Hepatitis B surface antigen was detected in 2 of 20 patients tested. 24% of the patients also had diabetes mellitus., 29% were anaemic, 29% were thrombocytopenic, 4% were leukopenic, and the prothrombin time was prolonged in 22%. The albumin/globulin ratio was reversed in 71% of the patients. The alkaline phosphatase was elevated in 56%, the aspartate aminotransferase was increased in 58% and the gamma glutamyl transpeptidase in 56%. 56% of the patients had macronodular cirrhosis; the liver showed a micronodular pattern in 18%; 7% had biliary cirrhosis; 7% chronic active hepatitis with cirrhosis; and 13% showed a mixed macro-micronodular pattern. Ascites and fluid overload developed in 44% of the patients. Hepatic encephalopathy occurred in 18% and upper gastrointestinal bleeding in 18%.

Chronic renal insufficiency ultimately culminating in end-stage renal disease requiring dialysis or transplantation is a major health problem in the United States. The first task confronting the physician caring for a patient with renal disease is to decide whether the renal insufficiency is acute or chronic. The initial differential diagnostic approach to chronic renal insufficiency consists of determining whether the patient has glomerular disease or interstitial or vascular disease on the basis of a careful history taking, urinalysis, and measurement of 24-hour protein excretion. Further refinement of diagnostic considerations often requires serologic studies, renal biopsy, or imaging the urinary tract with ultrasonography or computed tomography. Management considerations begin with the identification and correction of any acute reversible causes of renal insufficiency in patients with chronic renal disease. Recent studies have shown that effective antihypertensive therapy, especially with angiotensin-converting enzyme inhibitors, restriction of dietary protein, and excellent glycemic control in patients with diabetes, can retard the progression of chronic renal disease. Once these therapeutic strategies are in place, it is important to anticipate and treat the multiple manifestations of chronic progressive renal insufficiency: fluid overload, hyperkalemia, metabolic acidosis, abnormalities of calcium, phosphorus, and vitamin D metabolism, and anemia.
