Abstract

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.
