Incidence of intradialytic hypertension in hemodialysis patients in Beheira governorate and effect of high flux versus low flux dialysis on it

Abstract

Abstract Background Intradialytic hypertension (IDH) is a common complication of hemodialysis (HD) that is under-recognized and its significance is underappreciated. No standard definition of IDH exists. As a unifying criteria for the diagnosis of IDH has not been proposed, the focus of this review will be on systolic blood pressure (SBP) rise = 10 mmHg at = 4 over six consecutive sessions. IDH is estimated at 5–15% of HD patients. IDH has been associated with poor clinical outcomes in HD patients including increased hospitalizations, higher ambulatory blood pressure (BP), cardiovascular morbidity, and mortality. Aim of the Work To detect the incidence of IDH in HD patients in Beheira governorate and to compare the effect of high flux versus low flux dialysis on it. Patients and Methods This study was conducted on 200 patients on maintenance HD from different HD units in Beheira governorate. The patients were divided into two groups: Group 1: 100 patients on HD with high flux dialyzers and Group 2: 100 patients on HD with low flux dialyzers. Results: Incidence of IDH in HD patients in Beheira governorate was 23.5% at the start, 21% after one month and 13% after three months duration. Results of our study demonstrated that there were no significant differences between both groups as regards effect of high-flux vs low-flux dialysis on IDH after one month and at the end of the study (P > 0.05), but there was a significant decrease in number of IDH patients after one month duration and after three months in both high-flux and low-flux dialysis patients. In our study, there was significant improvement in the form of reductions in all of pre-dialysis BUN, post-dialysis BUN, serum creatinine levels and serum IPTH levels at the end of the study in high flux group compared to low flux group. Finally, our results showed significant improvement in serum hemoglobin levels in high flux group by the end of the study in contrast to the low flux group. Conclusion No significant difference in the effect of high flux versus low flux dialysis on IDH, but there was significant improvement in all of pre-dialysis BUN, post-dialysis BUN, serum creatinine levels and serum IPTH levels by the end of the study in the high flux group compared to the low flux group.
