Ultrafiltration Versus Intravenous Diuretics for Patients Hospitalized for Acute Decompensated Heart Failure Maria Rosa Costanzo, Maya E. Guglin, Mitchell T. Saltzberg, Mariell L. Jessup, Bradley A. ...Bart, John R. Teerlink, Brian E. Jaski, James C. Fang, Erika D. Feller, Garrie J. Haas, Allen S. Anderson, Michael P. Schollmeyer, Paul A. Sobotka, for the UNLOAD Trial Investigators Among 200 volume-overloaded heart failure patients randomized to ultrafiltration or intravenous diuretics, 48-h weight (5.0 ± 3.1 kg vs. 3.1 ± 3.5 kg; p = 0.001) and net fluid loss (4.6 vs. 3.3 l; p = 0.001) were greater in the ultrafiltration group. Dyspnea scores were similar. At 90 days, the ultrafiltration group had fewer heart failure rehospitalizations per patient (0.22 ± 0.54 vs. 0.46 ± 0.76; p = 0.022) and patients presenting for unscheduled visits (21% vs. 44%; p = 0.009). No serum creatinine differences occurred between groups. Nine deaths occurred in the ultrafiltration group and 11 in the diuretics group.
Abstract Background SERCA2a deficiency is commonly seen in advanced heart failure (HF). This study is designed to investigate safety and biological effects of enzyme replacement using gene transfer ...in patients with advanced HF. Methods and Results A total of 9 patients with advanced HF (New York Heart Association NYHA Class III/IV, ejection fraction EF ≤30%, maximal oxygen uptake VO2 max <16 mL·kg·min, with maximal pharmacological and device therapy) received a single intracoronary infusion of AAV1/SERCA2a in the open-label portion of this ongoing study. Doses administered ranged from 1.4 × 1011 to 3 × 1012 DNase resistant particles per patient. We present 6- to 12-month follow-up data for these patients. AAV1/SERCA2a demonstrated an acceptable safety profile in this advanced HF population. Of the 9 patients treated, several demonstrated improvements from baseline to month 6 across a number of parameters important in HF, including symptomatic (NYHA and Minnesota Living with Heart Failure Questionnaire, 5 patients), functional (6-minute walk test and VO2 max, 4 patients), biomarker (NT-ProBNP, 2 patients), and LV function/remodeling (EF and end-systolic volume, 5 patients). Of note, 2 patients who failed to improve had preexisting anti-AAV1 neutralizing antibodies. Conclusions Quantitative evidence of biological activity across a number of parameters important for assessing HF status could be detected in several patients without preexisting neutralizing antibodies in this open-label study, although the number of patients in each cohort is too small to conduct statistical analyses. These findings support the initiation of the Phase 2 double-blind, placebo-controlled portion of this study.
