Is predialysis plasma BNP level associated with nutritional markers in chronic hemodialysis patients?
p-value: p=0.03
In chronic hemodialysis patients, elevated plasma BNP levels are associated with malnutrition markers rather than inflammation, potentially reflecting fluid overload difficulties in malnourished patients.
Chazot et al. (2009) conducted a cross-sectional in Chronic hemodialysis (n=51). Malnutrition vs. Patients not meeting malnutrition criteria was evaluated on Predialysis plasma BNP level (p=0.03). Malnutrition in hemodialysis patients was associated with significantly higher plasma BNP levels compared to patients without malnutrition (400 ± 405 vs. 202 ± 166 ng/l, p=0.03).
