Key result
Haemodialysis is linked to a ~63% rise in CGRP, correlating with lower systolic blood pressure.
Why the study?
Does haemodialysis increase plasma CGRP levels and correlate with blood pressure changes in dialysis patients?
Observational (n=12)
No
Does haemodialysis increase plasma CGRP levels and correlate with blood pressure changes in dialysis patients?
Absolute Event Rate: 114.5% vs 70.3%
Plasma levels of CGRP increase during haemodialysis and are negatively correlated with systolic blood pressure, suggesting a potential mechanism for dialysis-induced vasodilatation and hypotension.
No takes yet. Share an insight, caveat, or question.
CGRP rise may underlie intradialytic hypotension; hypothesis-generating for causality and targeted interventions in larger cohorts.
Odar‐Cederlöf et al. (1989) conducted an observational in Patients undergoing haemodialysis (n=12). Sequential ultrafiltration and haemodialysis vs. Baseline (start of treatment) was evaluated on Plasma levels of CGRP. Haemodialysis increased plasma CGRP levels from 70.3 pmol/L at baseline to 114.5 pmol/L, and these changes were strongly negatively correlated with changes in systolic blood pressure.
