Endogenous Nitric Oxide

Nitric oxide exerts multiple effects on renal function. It remains unclear whether endogenous nitric oxide production is increased or decreased in patients with chronic renal failure. To evaluate endogenous nitric oxide production in these patients we studied exhaled nitric oxide output by an ozone chemiluminescence method and plasma NO2-/NO3- levels by the Griess method in 40 patients with end-stage chronic renal failure who underwent regular continuous ambulatory peritoneal dialysis (n = 30) or haemodialysis (n = 10), and in 28 healthy subjects. Patients with chronic renal failure had a higher exhaled nitric oxide concentration [39±3 versus 19±1 parts per billion, (mean±S.E.M.), P< 0.0001], a greater nitric oxide output (177±11 versus 96±7 ;nl·min-1·m-2, P< 0.001) and a higher plasma NO2-/NO3- concentration (96±14 versus 33±4 ;μmol, P< 0.01) than controls. These values did not differ between patients on haemodialysis and those on continuous ambulatory peritoneal dialysis. Patients with chronic renal failure had significantly higher plasma concentrations of both interleukin-1β and interferon-γ than controls. The exhaled nitric oxide output did not correlate with plasma NO2-/NO3- or with peritoneal dialysate NO2-/NO3-, but plasma NO2-/NO3- correlated with dialysate NO2-/NO3- in patients who underwent continuous ambulatory peritoneal dialysis (r = 0.77, P< 0.01). Haemodialysis for 4 ;h acutely decreased plasma NO2-/NO3- (92±17 versus 50±8 ;μmol, P< 0.05) and cGMP concentration (16.5±4.3 versus 5.1±1.7 ;pmol/ml, P< 0.01), but did not decrease exhaled nitric oxide output. The increase in exhaled nitric oxide with the simultaneous increase in circulating cytokines suggests that nitric oxide synthase seems to be induced significantly in patients with chronic renal failure. Increased endogenous nitric oxide production may have a pathophysiological role in patients with uraemia.

Introduction: Nitric oxide (NO) plays an important role in a wide range of physiologic and pathophysiological processes. A major mediator of endothelial function, NO regulates vasodilatory and antithrombotic actions in the vasculature and plays a role in reproductive functions, bronchodilation, bone formation, memory, insulin sensitivity, and gastrointestinal relaxation. Impaired NO bioactivity is strongly associated with endothelial dysfunction. NO, an L-arginine derivative, also exerts a variety of renal and extrarenal physiological and pathophysiological effects. It seems that NO synthetic pathway could have a key role in mediating the complex hemodynamic and hemostatic disorders associated to the progression of renal disease. It remains unclear whether endogenous NO production is increased or decreased in patients with chronic renal failure. The objective of this study was to present the effect of different dialysis treatment on NO serum concentration in patients with chronic renal failure.Patients and Methods: To evaluate endogenous NO production in these patients we studied plasma NO2 and NO3 levels (determined with the Griess method) in patients who underwent regular continuous ambulatory peritoneal dialysis or repeated haemodialysis and in healthy subjects. The study included 51 patients suffering from chronic renal failure and 30 healthy subjects.Results: Our results show that patients with chronic renal failure had a significantly higher NO serum concentration than controls. These values did not differ between patients on haemodialysis and those on continuous ambulatory peritoneal dialysis. NO serum concentration did not differ between female and male independently of the patient’s treatment.Discussion and Conclusion: From obtained results we can concluded that uremia is associated with excessive systemic NO release independently of the patient’s treatment. Alter (increase) NO synthesis may help to explain some pathological changes seen in uraemia such as bleeding tendency, a well-known complication of uremia and hemodialysis hypotension.

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.
