Tuberculosis associated with dialysis was studied at the Renal Unit of the Tokyo Medical and Dental University and Yokosuka Mutual Aid Hospital Kidney Center, in both of which the treatments of chronic renal failure are the same. There are 12 tuberculosis patients out of 367 patients on maintenance hemodialysis from January 1967 to December 1976, an incidence of 3.3%. This was 6-16 times greater than that in the general population of this country according to yearly statistics. The characteristics of dialysis-associated tuberculosis include a high incidence of miliary tuberculosis, especially in aged patients and difficulty in establishing the diagnosis before death. Clinical features which are helpful in the early diagnosis are intermittent high fever of unknown origin, weight loss, anorexia, abnormalities of the central nervous system, erythrocyte sedimentation rate over 100 mm/h, leukocytosis and high value of the C-reactive protein. With the increasing number of dialysis patients, an increase of dialysis-associated tuberculosis is expected and this will be one of the major problems of dialysis patients in future.

In children with chronic renal failure (CRF) anorexia, nausea, and vomiting are common yet poorly understood symptoms. We studied oesophageal and gastric motor function in 12 children (age 7 months-6.8 years) with severe CRF not undergoing dialysis who had persistent anorexia and vomiting. Eight of 12 patients had significant gastro-oesophageal reflux (reflux index 5.2% to 21.9%, mean 11.3%; controls < 5%), 7/10 had altered gastric half emptying times (T1/2) for 5% glucose or milk (glucose meal--controls: 8-14 min, two CRF patients: 18-25 min; milk meal--controls: 48-72 min, five CRF patients 27, 28, 82, 83, and 110 min). Gastric antral electrical control activity was abnormal in 6/11 patients, with different types of gastric dysrhythmias whereas the remainder and controls showed a regular dominant frequency of 0.05 Hz. In 7/9 patients fasting serum gastrin concentration was raised (53 to > 400, mean 168 pmol/l, controls < 40 pmol/l). All CRF patients with anorexia and vomiting had one or more disorder of foregut motility. The nature and variety of the motor disorders and the raised concentrations of circulating gastrin suggest that the normal environment generated by CRF affects the function of the smooth muscle of the foregut.

Since August, 1984 renal replacement therapy with haemodialysis, peritoneal dialysis and renal transplant has been carried out regularly at the renal unit of the Kenyatta National Hospital (KNH). Various nutritional disturbances have been met. Nausea, vomiting and anorexia have been noticed frequently particularly in those on intermittent peritoneal dialysis (IPD). The same problems were experienced in those few patients who were on continuous ambulatory peritoneal dialysis (CAPD). The patients were usually malnourished, the malnutrition being of protein-calorie type. At the start of the programme of renal replacement therapy in 1984, the problems of poor nutrition were worse but are currently improving. At the moment our patients with chronic renal failure (CRF) and end stage renal disease (ESRD) on dialysis are scattered all over the medical and paediatric wards at KNH. This has impeded the smooth surveillance of patients' diets by the few available nutritionists. The review of our performance from 1984-1988 on the nutritional status of patients with CRF and ESRD is an attempt to create a normal dietary cover for patients with the above problems.

Renal failure in itself generates a state of malnutrition, due to three main causes: inadequate ingestion (anorexia, vomiting or diet insufficiencies), the existence of catabolic factors (proteins, acidosis, PTH) and extrarenal depuration (which provokes a lack of amino acids and vitamins). Artificial nutrition constitutes a series of measures that can be adopted to act upon each of the above causes. Adequate ingestion compared to inadequate ingestion can be performed orally (especially in chronic renal failure) by parenteral administration (preferable in acute renal failure) and enteral administration (complementary in both cases). The quantity and quality of adequate nutrients is non-dependent on the method of administration; 500 ml, of water should be administered plus diuresis, plus loss from other tracts; the mineral intake of sodium, potassium and phosphorus should be restricted; in the case of vitamins, these should be administered, especially the B and D complexes; there should be sufficient calories to constitute a hypercaloric diet (from 30-50 kg/day), at least 50% in the form of carbohydrates (hypertonic glucose, if administered intravenously, and dextrinolmaltose or starch if administered through the digestive tract) and at least 40% in the form of lipids (preferably of vegetable origin, rich in non-saturated fatty acids); proteins are the mainstay of nutrition in renal failure; thus, with a normal renal function or in dialysis, a dose of 1 g/kg/day is recommended; in chronic renal failure, 0.5 g/kg/day; in cases of renal failure not on dialysis, 0.3 g/kg/day, supplemented by essential amino acids or cetoacids (the effectiveness of the latter is still in dispute).(ABSTRACT TRUNCATED AT 250 WORDS)

A few of the many reports of experimental chronic renal failure have been summarized. Anorexia and food selection have been studied in experimental uremia and the findings are comparable with those observed in uraemic children. The optimal dietary protein content for growth is close to the minimal requirement for "optimal" growth. Protein excess leads to growth retardation and renal deterioration in uraemic rats, at least with the commonly used dry diets. The increased water requirement may be more critical for growth than the blood urea level or acidosis, although this requires further investigation. Reduction of the dietary protein by 50% and supplementation with essential amino acids (EAA) results in growth similar to that of the 100% protein diet. There is no growth improvement despite low blood urea levels, but the renal parenchymal is preserved. Supplementation with nitrogen-free analogues is more frequently associated with defective growth; the optimal mixture remains to be defined, and to date, when nutrition is identical, nitrogen-free analogues offer no benefit for renal preservation compared with EAA. Sucrose-rich diets have adverse effects on uraemia. These effects are associated with fructose intolerance and with reduced energy storage in the liver. The precise metabolic alteration remains to be defined.

A clinical trial, to evaluate the effects of a Chinese herbal drug, Rheum E and angiotensin converting enzyme inhibitor, Captopril on chronic renal failure (CRF), was conducted. Thirty cases with initial serum creatinine (Scr) levels of 344.8 +/- 114.0 mumol/L were allocated randomly to 3 groups: Rheum E treated group, Captopril treated group and Rheum E + Captopril group. A control group of 12 cases were on dietary therapy alone. During the 6-22 months of treatment, all the patients were kept on low-protein (0.6g/kg/d), and low-phosphorus (10mg/kg/d) diet. The results showed that the progression rate of renal failure, calculated by regression analysis of 1/Scr vs time, was found to be retarded after treatment with the increased regression coefficient (b value). Scr levels and blood urea nitrogen were kept stable or fell slightly. Albumin rose during the follow-up period (P less than 0.05) in the treated patients, being more marked in both Rheum E and Rheum E + Captopril groups. Uremic symptoms of nausea, anorexia improved in most of the treated patients. It is concluded that long-term low-dose Rheum E taken orally is beneficial to CRF. Its effect is better than that of Captopril. The regime of Rheum E and Captopril is a preferable choice in the long-term treatment for preventing progression of CRF.

The main objectives of medical and nutritional management of patients with chronic renal failure are to slow down the progression of renal disease and to prevent secondary complications due to hypertension, uremic metabolic disturbances, and bone disease. The importance of nutritional measures for this purpose is increasingly recognized. In the setting of vitamin D and calcium deficiency secondary hyperparathyroidism and retention of phosphate result in renal osteodystrophy. An increase in dietary calcium and avoidance of foods rich in phosphate are important. In some patients supplementation of vitamin D3 may be necessary while calcium homeostasis is monitored during follow up. The dietary protein content can influence the severity of the uremic state. Normal or increased consumption of protein may accelerate the progression of renal disease due to the accumulation of nitrogenous products. In addition, uremia itself may cause loss of appetite and thus accumulation of endogenous nitrogen compounds as a result of protein catabolism. Protein restriction under such circumstances may cause malnutrition and an associated increase in morbidity and mortality. Thus, dietary management must consist of individually designed restriction of total protein intake with ingestion of high value protein. This allows balanced nitrogen metabolism with a reduction in circulating uremic toxins.

We recently demonstrated elevated plasma amino acid concentrations and abnormal responses to amino acid supplementation (e.g., elevated methionine and phenylalanine) in children with chronic renal failure (CRF). We also recently developed an improved model of CRF in which animals manifest abnormal tissue amino acid levels, marked anorexia and growth failure. The objective of the current study was to determine the etiology of elevations of sulfur amino acids in animals with chronic renal failure. Chronic renal failure, defined as creatinine clearance less than 30% of control values, was induced in male rats in a two-stage surgical procedure. Four groups were studied over 2, 4 and 6 wk: control (non-operated) control (sham-operated), pair-fed (sham-operated and pair-fed with uremics) and CRF. Animals with CRF were anorexic and growth-retarded. Although plasma sulfur amino acid levels tended to be lower in the uremic animals than in controls, hepatic tissue concentrations were higher. Methionine adenosyltransferase was higher, but cystathione synthase and cystathionase activities were not significantly different in rats with CRF compared to pair-fed controls. We conclude that uremia, not malnutrition, affected sulfur amino acid metabolism and that with CRF, a normal adaptive response to elevated methionine levels was occurring, sufficient to normalize sulfur amino acid pool size. Alternative causes of elevated sulfur amino acids must be sought.

A 49-year-old man with an 11 year history of NIDDM presented hypercalcemic and with acute on chronic renal failure. His only symptoms were mild anorexia and nausea. Four years previously he had been diagnosed as having lipoid pneumonia, with classical histological findings. On this admission, serum parathyroid hormone was suppressed and 1,25 dihydroxyvitamin D levels elevated. The cause of his hypercalcemia presumably was ectopic 1 hydroxylation of 25 hydroxyvitamin D in the chronic granulomata in his lungs. It should be emphasised that any chronic granulomatous disease, and not just sarcoidosis, may be a cause of hypercalcemia.

A 48-year-old man was admitted for treatment of Cushing's syndrome due to right adrenal adenoma, associated with chronic renal failure (CRF) with a blood urea nitrogen level of 64.2 and serum creatinine level of 3.9 mg/dl. After removal of the adrenal adenoma, the CRF deteriorated with progressive symptoms of anorexia, vomiting and hypertension, and the patient was placed on hemodialysis. Prior to adrenalectomy, the 17 OHCS and 17 KGS in the urine were not so high. However, the urinary 17 KS was high with an elevated 11-oxy fraction. In comparison with 2 patients suffering from adrenal Cushing's syndrome with normal renal function, there were no large accumulated quantities of glucuronic conjugated and unconjugated metabolites in the plasma of the CRF Cushing's syndrome, with confirmation ascribable to the radioimmunoassayable cross-reactivity of the cortisol antiserum used in the radioimmunoassay kit. In the Cushing's syndrome with CRF, almost all the cortisol, which was hypersecreted from the adenoma, was presumed to be converted to the 11-oxy fraction of 17 KS, possibly by activation of hepatic enzymes.
