A Combination of Hemodialysis with Hemoperfusion Helped to Reduce the Cardiovascular-Related Mortality Rate after a 3-Year Follow-Up: A Pilot Study in Vietnam

AIMS: Moderate to severe hyperparathyroidism (parathyroid hormone [PTH] concentrations ≥600 pg/mL) may increase the risk of cardiovascular problems and bone disease. We assume that a combination of hemodialysis with hemoperfusion may reduce the cardiovascular-related mortality rate in maintenance hemodialysis. SUBJECTS AND METHODS: From 625 maintenance hemodialysis patients, 93 people met with our inclusion criteria. Based on the level of serum PTH, the patients were divided into 2 groups: 46 patients who underwent a combination of hemodialysis and hemoperfusion (HD + HP group) for consecutive 3 years and 47 patients who used hemodialysis only (HD group). RESULTS: During 3 years of follow-up, the ratio of mortality was 4.3% in the HD + HP group which was significantly lower than in the HD group (17%), p = 0.049. Based on Kaplan-Meier analysis of cardiovascular-related mortality, patients in the HD group (red line) exhibited a significantly higher death rate compared to the HD + HP group (violet line) (log-rank test, p = 0.049). CONCLUSION: We demonstrated that a combination of hemodialysis and hemoperfusion for 3 years helped to reduce the cardiovascular-related mortality rate.
