Kidney transplantation and kidney donation do not affect short-term blood pressure variability.

What is the context? Previous studies have shown that both office and ambulatory BP levels are significantly reduced after kidney transplantation in KTRs.On the other hand, existing evidence suggests that kidney donors' BP levels do not change significantly after kidney donation.Existing studies on BPV in KTRs are limited. The available data for living kidney donors are even fewer.What is new? This is the first study assessing short-term BPV levels in ΚTRs undergoing living donor kidney transplantation, and their respective donors in short-term and mid-term follow-up. The main findings were:All 24-h, daytime and night-time BPV indexes did not change significantly from baseline to 3- and 12-month evaluation after kidney transplantation in the KTRs.No significant changes for the 24-h, daytime and night-time BPV were observed in their respective kidney donors at the same follow-up periods.What is the impact?High BPV, which seems to remain unaltered after kidney transplantation, may be one of the many factors involved in the high cardiovascular risk observed in KTRs.Unchanged BPV levels further supports the evidence suggesting no higher risks of arrhythmias, cardiovascular events or death after living kidney donation.
