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.

We present two patients with Hantaan virus infection, admitted to the Department of Nephrology, Skopje, at the same time, with the same clinical presentation (chills, fever, abdominal pain, hemorrhages, nausea, headache, proteinuria, hematuria, oliguria, acute renal failure) but with different pathohistological findings and different disease courses. In the first case diffuse proliferative glomerulonephritis was found, with a complete recovery of renal function after a month, with a mild proteinuria and erythruria during the second and the third month. In the second case, glomeruli were normal in general, with slight mesangial proliferation found in two out of twenty, but interstitial edema, lymphocyte infiltrations and tubular changes were noted. Complete recovery was not noted after 3 months of follow-up. The patient is now without hemodialysis treatment, with polyuria, in the stable phase of chronic renal failure which is not improving.

Effects of acetate and bicarbonate dialysates on tolerance to dialysis have been examined in 30 patients with chronic renal failure (CRF). Symptomatic homeostatic impairment (nausea, vomiting, headache) and cardiovascular instability (tachycardia, arrhythmia, dyspnea) were less common (p less than 0.05) in bicarbonate dialysis. The cardiovascular symptoms correlated with antihypertensive effects of acetate (p = +0.48). Tolerance to ultrafiltration was better with bicarbonate dialysis. Gas chromatographic measurement of blood acetate concentrations in 7 patients on bicarbonate dialysis showed them to be 1.4 +/- 0.31 mmol/l at the beginning of dialysis treatment and 1.7 +/- 0.24 mmol/l at its end (normal, 1.7 +/- 0.14 mmol/l). Of 26 patients on acetate dialysis, 9 patients showed initial and late acetate concentrations of 1.7 +/- 0.26 and 2.5 +/- 0.23 mmol/l, respectively, while in 17 patients an initial concentration of 4.8 +/- 0.32 mmol/l rose to 9.0 +/- 1.1 mmol/l at the end of the treatment (p less than less than 0.01). Dialysis-induced complications had a higher incidence in the latter group (p less than 0.02). Acetate dialysis was poorly tolerated by 65% of the patients. The intolerance was aggravated by myocardial lesions and slow acetate turnover indicated by blood acetate concentrations above 7-8 mmol/l.

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 pharmacokinetics of quinapril, a novel angiotensin converting enzyme (ACE) inhibitor, and its active metabolite, quinaprilat, were determined following a single 20-mg oral dose of quinapril in six patients with chronic renal failure maintained on continuous ambulatory peritoneal dialysis (CAPD). Overall, quinapril was well tolerated by these CAPD patients, with mild and transient side effects, not unexpected in this clinical setting, which included pruritus, headache, nausea, and cough. Blood pressure reduction was observed in four of six patients, with onset reliably two to four hours after dosing and duration up to 48 hours, associated with quinaprilat concentrations in plasma above 90 ng/mL for at least 33 hours postdose. Two patients experienced significant hypotension, systolic blood pressure below 90 mm Hg, which responded promptly to oral fluid administration and/or reduction in dialysate tonicity. The pharmacokinetic profile of quinapril in these CAPD patients was not significantly different from that previously observed in healthy subjects with normal renal function and in patients with moderate to severe renal dysfunction not yet requiring dialysis (RDND). The apparent elimination half-life of quinapril was approximately one hour, with negligible dialysate excretion. The pharmacokinetic profile of quinaprilat in these CAPD patients was similar to that previously observed in patients with RDND. The elimination half-life of quinaprilat was markedly prolonged when compared to that in healthy subjects and averaged 20 hours, with only a small amount of quinaprilat excreted in dialysate (mean = 2.6% of total dose).(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Effect of lactulose therapy was examined in patients with chronic renal failure (CRF) prior to hemodialysis (HD). Twenty three patients were included in this study. Ten out of the 23 patients were continuously treated with lactulose at a dosage of 18 g/day for eight weeks. However, 12 out of the 23 patients dropped out because of nausea and/or watery diarrhea during the therapy. One patient was transfered to HD one month after the beginning of lactulose therapy. Ratios of guanidinosuccinic acid (GSA) in plasma after eight weeks were significantly lower than those before treatment. Cessation of treatment was significantly related to worsening of the GSA (p less than 0.01). It seems that lactulose therapy could be useful in the treatment of CRF if compliance of the therapy is maintained after reducing some adverse effects.

Twenty consecutive patients with chronic renal failure (CRF) and 20 control patients received subarachnoid anaesthesia with 3 ml of 0.75% bupivacaine plain for surgery in the lower abdomen. Sensory analgesia (onset) developed significantly more rapidly in the CRF patients: maximum segmental level of pin-prick analgesia was reached in an average of 21 min in the CRF patients and in 35 min in the control patients. An observed tendency to acidosis and a possible reduced intrathecal space in the uraemic patients may account for the more rapid blockade. The mean spread of the sensory block in CRF patients (T4) was two segments higher than that in the control patients, but because of marked inter-individual variation this difference cannot be considered clinically important. Three CRF patients and two control patients had insufficient analgesia for surgery. In the CRF patients, both sensory and motor blockades were of shorter duration than in the control patients. The incidence of complaints of nausea and backache was similar in the groups. One control patient had a headache.

Previous intravital staining techniques for parathyroid localisation have met with variable success and complications. Modification of these techniques, employing a more consistent dose, combined with a prolonged infusion time has provided more uniform staining of normal and abnormal parathyroid tissue, other tissues showing little or no colour change. Locally induced oedema, not previously described, was found to be a great asset in the dissection of glands. In 38 of 40 patients (95%), 4 glands were demonstrated and in the remaining 2 cases, only 3 glands appeared to be present. One case alone has required reoperation, due to the presence of a fifth gland. Intra-thyroid and intra-thymic tumours were found easily, as was glandular tissue split accidentally. Apart from slight nausea in one patient, there were no complications attributable to the dye, in the series which included 12 patients with chronic renal failure. Uniformly normal postoperative serum calcium levels indicated the accuracy of the method. The technique is safe, inexpensive and easily reproducible, and would seem to have many advantages over other methods of tumour localisation.
