In 37 patients with chronic renal failure (CRF) serum amylase was higher than in 33 normal subjects (483 U/L ± SD 185 versus 267 ± SD 66 U/L, p < 0.05); while the percentage of pancreatic isoenzymes was within normal limits in 34 patients and only slightly increased in 3. Seventeen of the patients were on conservative treatment, 10 on hemodialysis and 10 on continuous ambulatory peritoneal dialysis; no significant differences in serum amylase levels were detected between these subgroups. No correlation was found between serum BUN or creatinine and serum amylase but a positive correlation was found between these enzyme levels and duration of CRF (p < 0.05) in the patients on conservative treatment.

The Mean

1. Erythrocyte choline transport has been studied in nine patients on maintenance haemodialysis for chronic renal failure, six patients on continuous ambulatory peritoneal dialysis, 31 patients with renal transplants and in nine normal control subjects. 2. The mean maximum rate of choline influx (Vmax., measured at an extracellular choline concentration of 250 μmol/l) was 66.7 (sd 14.1) μmol h−1 l−1 cells in patients on haemodialysis, 87.8 (sd 18.5) μmol h−1 l−1 cells in patients on continuous ambulatory peritoneal dialysis and 30.5 (sd 4.9) μmol h−1 l−1 cells in control subjects. The increase in choline flux in patients on haemodialysis and patients on continuous ambulatory peritoneal dialysis compared with control subjects was highly significant (P < 0.001). 3. Renal transplant patients showed variable values for the Vmax. of choline influx (range 17.7-71.7 μmol h−1 l−1 cells). The values showed a signifcant negative correlation with creatinine clearance and this correlation correctly extrapolated to the maximum choline flux in normal subjects and in patients on dialysis. 4. The kinetics of choline transport have been studied in erythrocytes of patients on haemodialysis and control subjects in ‘zero-trans’ conditions after depletion of intracellular choline. The mean Vmax. in these conditions was 38.4 (sd 4.6) μmol h−1 l−1 cells in patients on haemodialysis compared with 14.2 (sd 3.7) μmol h−1 l−1 cells in control subjects. The mean Km under ‘zero-trans’ conditions was 19.4 (sd 2.4) μmol/l in patients on haemodialysis and 7.4 (sd 1.4) μmol/l in control subjects. These differences were significant (P < 0.001).

Lipoprotein Composition

AbstractStudies were carried out in 183 non-dialyzed, 123 hemodialysis, 81 continuous ambulatory peritoneal dialysis and 35 post-transplant patients and in 103 healthy subjects as a reference group. Lipids and apolipoprotein (apo)AI and apoB were determined using Roche kits. An anti-apoB antibody was used to separate apoB-containing apoCIII and apoE-triglyceride-rich lipoprotein (TRL) in the non-high-density lipoprotein (non-HDL) fraction from apoCIIInonB and apoEnonB in the HDL fraction in four groups of patients with chronic renal failure (CRF) and healthy subjects. Multivariate linear regression analysis was used to investigate the relationship between triglyceride (TG) or HDL-cholesterol (HDL-C) concentrations and lipoproteins. Dyslipidemia varied according to the degree of renal insufficiency, the type of dialysis and therapy regime in CRF patients. Lipoprotein disturbances were manifested by increased TG, non-HDL-C and TRL concentrations, and decreased HDL-C and apoAI concentrations, whereas post-renal transplant patients showed normalization of lipid and lipoprotein profiles, except for TG levels and total apoCIII and apoCIIInonB. The present study indicates that CRF patients have disturbed lipoprotein composition, and that hypertriglyceridemia and low HDL-C concentrations in these patients are multifactorial, being secondary to disturbed lipoproteins. The method using anti-apoB antibodies to separate apoB-containing lipoproteins in the non-HDL fraction from non-apoB-containing lipoproteins in HDL can be used in the diagnosis and treatment of patients with progression of renal failure or atherosclerosis. The variability of TG and HDL-C concentrations depends on the variability of TRL and cholesterol-rich lipoprotein concentrations, but the decreases in TG and increases in HDL-C concentrations are caused by apoAI concentration variability. These relationships, however, need to be confirmed in further studies.

Introduction:Most of patients with chronic renal failure are affected by normochromic, normocytic anemia caused by different etiological factors. Anemia causes a series of symptoms in chronic renal failure, which can hardly be recognized from the uremic signs. Anemia adds to morbidity and mortality rates in patients affected by advanced chronic renal failure. Blood count partially improves during the first months after starting the chronic renal replacement therapy, in correlation with the quality of depuration program, with extension of erythrocyte lifetime and with hemoconcentration due to reduction of plasma volume. Recent trials found that higher residual renal function (RRF) significantly reduced co-morbidity, the rate and duration of hospitalization and risk of treatment failure. Objective: The aim of the study was to follow blood count parameters in 32 patients on chronic continuous ambulatory peritoneal dialysis (CAPD) during the first six months of treatment, to evaluate the influence of demographic and clinical factors on blood count and RRF, and to examine the correlation between RRF and blood count parameters. Method: A total of 32 patients affected by end-stage renal disease of different major cause during the first six months of CADP treatment were studied. RRF and blood count were evaluated as well as their relationship during the follow-up. Results: Blood count significantly improved in our patients during the first six months of CAPD treatment even if Hb and HTC failed to reach normal values. Iron serum level slightly decreased because of more abundant erythropoiesis and iron utilization during the first six months of treatment. RRF slightly decreased. After six months of CAPD treatment, the patients with higher RRF had significantly higher Hb, HTC and erythrocyte number and a lot of positive correlations between RRF and anemia markers were observed. Conclusion: After 6-month follow-up period, the patients with higher RRF had significantly higher blood count parameters, and several positive correlations between RRF and blood count markers were confirmed.

Major Complication

This study describes our experience with continuous ambulatory peritoneal dialysis (CAPD) over a four year period, during which 88 patients were offered CAPD. It compares and contrasts the response to CAPD among four racial groups in Natal viz asiatics, blacks, coloureds and whites. Peritonitis -the major complication, occurred with an overall incidence of one episode every 4.41 patient months. CAPD remains a useful alternative therapy in developing countries where a high percentage of patients with chronic renal failure would be denied a chronic renal failure program because of lack of expertise in hemodialysis and/or renal transplantation, or limited financial resources. Continuous ambulatory peritoneal dialysis (CAPD) was first described by Moncrief and Popovich (1) and, since its modification by Oreopoulos and his group (2), this technique has gained world wide usage. South Africa, like many developing countries has a high incidence of end-stage renal disease (ESRD) but because of lack of resources and economical problems, few patients with ESRD can be treated by dialysis or renal transplantation. CAPD affords a relatively simple and inexpensive form of therapy for these patients. At the present time about 200 patients are on CAPD in South Africa. Natal, the smallest of four provinces in South Africa, has a population of about five million, the majority being blacks. The minority groups include whites, asiatics and coloureds. There is only one chronic dialysis centre in Natal; situated in Durban, it serves the entire province including parts of the Transkei. This paper describes a four-year experience with CAPD in this mixed population and discusses problems unique to this situation.
