Abstract
Summery and conclusion
Chronic kidney disease is a chronic illness with high incidence rate which has a direct and indirect effect on all body organs.
Patients on maintenance haemodialysis should be followed up with regular investigations to assessed serum calcium, serum phosphorous level and nutritional status.
Pulse pressure is the difference between systolic and diastolic blood pressure, and the change in blood pressure seen during a contraction of the heart.
The study population included 75 patients undergoing maintenance haemodialysis during 2010 at Bab elsherea University Hospital at Cairo.
The aim of the work is to study the relation between pulse pressures, nutritional status and serum calcium, phosphorus level in patient with end stage renal disease on maintenance haemodialysis.
In this work we found that:-
- The increasing of Serum Calcium is associated with increase in pulse pressure with non-significant value.
-The increasing of Serum phosphorus is associated with decrease in pulse pressure with non-significant value.
-The increasing of Serum Calcium × Serum phosphorus value is associated with increase in pulse pressure with non-significant value.
- The correlation between pulse pressure and serum calcium was found to be positively correlated with no significance (p< 0.05, r= 0.232).
- The correlation between pulse pressure and serum phosphorus was found to be positively correlated with no significance relation was observed (p< 0.05, r= 0.057).
- The correlation between pulse pressure and serum calcium × serum phosphorus was found to be positively correlated with no significance (p< 0.05, r= 0.187).
- The decreasing in nutritional parameters is associated with increasing in the pulse pressure with significant value in both of (TSF, BMI, and Serum albumin) and non-significant value In (MAC).
-The correlation between pulse pressure and serum albumin was found to be negatively correlated with significance relation was observed (p< 0.05, r=- 0.427).
- The correlation between pulse pressure and body mass index was found to be negatively correlated with significance (p< 0.05, r= -0.553).
- The correlation between pulse pressure and mean arm circumference was found to be negatively correlated with significance (p< 0.05, r= -0.268).
- The correlation between pulse pressure and triceps skin fold was found to be negatively correlated with significance (p< 0.05, r= -0.547).
- The correlation between pulse pressure and blood hemoglobin was found to be negatively correlated with no significance relation was observed (p< 0.05, r= -0.109).
So that the improvement of the nutritional stat and the proper control of serum calcium and phosphorous level may be lead to decrease cardiovascular events in ESRD under maintenance haemodialysis and decrease morbidity and mortality rate in these category of patients.
More research is needed before the interrelationship between malnutrition, inflammation, calcium and phosphorus serum level, pulse pressure; endothelial dysfunction, vascular calcification and heart disease in patients with ESRD can be established.
