The establishment and monitoring of dry weight in patients with advanced chronic kidney disease undergoing hemodialysis remains one of the greatest daily challenges in their clinical management. It has been demonstrated that physical examination alone is insufficient to provide an accurate assessment of volemic status and, therefore, to detect volume overload.
We conducted a prospective, observational, single-center study including 12 patients (11 males and 1 female; mean age 72 years), with a follow-up period of 2 months. The primary objective was to correlate pulmonary and venous ultrasound findings with standard markers of congestion, such as physical examination and bioimpedance, as well as with serum levels of NT-ProBNP (N-terminal prohormone of brain natriuretic peptide) and Ca125 (Ovarian cancer-related tumor marker).
During the follow-up period, survival was 100% after implementation of the intervention. At baseline, lung ultrasound showed a mean of 7 B-lines pre-dialysis and 2 post-dialysis. VExUS score (Venous Excess Ultrasoung Grading System) averaged 1 pre-dialysis and 0.08 post-dialysis. Mean NT-ProBNP values decreased from 14,180 pg/ml pre-dialysis to 5,721 pg/ml post-dialysis. Mean Ca125 levels were 17 U/ml at baseline and 22 U/ml post-dialysis. Patients with higher bioimpedance-measured overhydration also presented with a greater number of pre-dialysis B-lines and higher VExUS scores.
The combined use of lung and venous ultrasound emerges as a valuable tool to provide a comprehensive and objective assessment of volemic status in hemodialysis patients. It also allows for characterization of congestion phenotypes and for dynamic monitoring of therapeutic interventions throughout dialysis sessions.
Post-dialysis NT-ProBNP levels, following adequate ultrafiltration, may have diagnostic and follow-up value when compared with values measured during episodes of acute heart failure or clinical congestion, particularly of intravascular origin. In conclusion, in maintenance hemodialysis patients, a lung ultrasound– and venous ultrasound–guided strategy safely reduced congestion and was free of adverse effects.
