Interleukin-1 Blockade in Acute Decompensated Heart Failure: A Randomized, Double-Blinded, Placebo-Controlled Pilot Study.


ABSTRACT: Heart failure is an inflammatory disease. Patients with acute decompensated heart failure (ADHF) exhibit significant inflammatory activity on admission. We hypothesized that Interleukin-1 blockade, with anakinra (Kineret, Swedish Orphan Biovitrum), would quench the acute inflammatory response in patients with ADHF.We randomized 30 patients with ADHF, reduced left ventricular ejection fraction (<40%), and elevated C reactive protein (CRP) levels (?5 mg/L) to either anakinra 100 mg twice daily for 3 days followed by once daily for 11 days or matching placebo, in a 1:1 double blinded fashion. We measured daily CRP plasma levels using a high-sensitivity assay during hospitalization and then again at 14 days and evaluated the area-under-the-curve and interval changes (delta).Treatment with anakinra was well tolerated. At 72 hours, anakinra reduced CRP by 61% versus baseline, compared with a 6% reduction among patients receiving placebo (P = 0.004 anakinra vs. placebo).Interleukin-1 blockade with anakinra reduces the systemic inflammatory response in patients with ADHF. Further studies are warranted to determine whether this anti-inflammatory effect translates into improved clinical outcomes.

<h4>Background</h4>Heart failure is an inflammatory disease. Patients with acute decompensated heart failure (ADHF) exhibit significant inflammatory activity on admission. We hypothesized that Interleukin-1 blockade, with anakinra (Kineret, Swedish Orphan Biovitrum), would quench the acute inflammatory response in patients with ADHF.<h4>Methods</h4>We randomized 30 patients with ADHF, reduced left ventricular ejection fraction (<40%), and elevated C reactive protein (CRP) levels (≥5 mg/L) to eit  ...[more]
