Background: Febuxostat has been reported to have a stronger effect on hyperuricemia than allopurinol. Methods and Results: Cardiac surgery patients with hyperuricemia (n=141) were randomized to a febuxostat group or an allopurinol group. The study was single-blind, so the treatment was not known by the investigators. The primary endpoint was serum uric acid (UA) level. Secondary endpoints included serum creatinine, urinary albumin, cystatin-C, oxidized low-density lipoprotein (LDL), eicosapentaenoic acid/arachidonic acid ratio, total cholesterol, triglycerides, LDL, high-density lipoprotein, high-sensitivity C-reactive protein, blood pressure, heart rate, pulse wave velocity (PWV), ejection fraction, left ventricular mass index (LVMI), and adverse reactions. UA level was significantly lower in the febuxostat group than the allopurinol group from 1 month of treatment onward. Serum creatinine, urinary albumin, cystatin-C and oxidized LDL were also significantly lower in the febuxostat group. There were no significant changes in systolic blood pressure, PWV, and LVMI in the allopurinol group, but these parameters all had a significant decrease in the febuxostat group. Conclusions: Febuxostat was effective for high-risk cardiac surgery patients with hyperuricemia because it reduced UA more markedly than allopurinol. Febuxostat also had a renoprotective effect, inhibited oxidative stress, showed anti-atherogenic activity, reduced blood pressure, and decreased PWV and LVMI.  (Circ J 2013; 77: 2043–2049)

Purpose: Recently, guidelines recommended the use of direct oral anticoagulants (DOACs) for the management of non-valvular atrial fibrillation (NVAF). Postoperative atrial fibrillation (POAF) is the most common post-surgical complication of cardiac surgery, but the efficacy and safety of DOAC for POAF have rarely been investigated. We conducted a prospective observational study to investigate the efficacy and safety of DOAC administered immediately after POAF.Materials and Methods: In all, 135 patients that experienced POAF after cardiac surgery were treated with a DOAC. Primary endpoints were either bleeding or thromboembolic events. Secondary endpoints included changes in hemoglobin (Hb), prothrombin time (PT), activated partial thromboplastin time (APTT), serum creatinine (sCr), estimated glomerular filtration rate (eGFR), and pleural/pericardial effusion.Results: Patients were treated with apixaban (n = 31), edoxaban (n = 87), and rivaroxaban (n = 17). Major bleeding (p = 0.011) and gastrointestinal (GI) bleeding (p = 0.047) were significantly more frequent in the rivaroxaban group. Stroke was observed in one rivaroxaban group patient and none in the other two groups.Conclusion: DOAC as anticoagulation therapy for the early intervention of POAF following cardiac surgery is associated with a low incidence of major bleeding; a favorable safety profile and excellent efficacy were demonstrated for DOAC. Furthermore, our results indicate that the safety and efficacy of apixaban and edoxaban are better than rivaroxaban.

Background: The TROFEO trial demonstrated that febuxostat causes greater and more rapid reduction of serum uric acid (s-UA) than topiroxostat. We compared these drugs in patients with chronic kidney disease (CKD) by sub-analysis of the TROFEO trial.Methods: This sub-analysis targeted patients with an estimated glomerular filtration rate (eGFR) ≤60 mL/min/1.73 m2. The primary endpoint was the s-UA level. Secondary endpoints included creatinine, eGFR, urinary albumin, cystatin-C, oxidized low-density lipoprotein (Ox-LDL), eicosapentaenoic acid/arachidonic acid ratio, lipid biomarkers, high-sensitivity C-reactive protein, and B-type natriuretic peptide (BNP).Results: There was no significant difference of s-UA between the two groups either before or after treatment. However, s-UA did not exceed 6.0 mg/dL in febuxostat group during the study period, but it exceeded this level in seven patients from topiroxostat group, with the number being significantly higher in topiroxostat group. Serum creatinine (s-Cr) and eGFR were significantly better after 6 months of febuxostat treatment compared with topiroxostat Cystatin-C was significantly lower after 6 months of febuxostat treatment compared with topiroxostat. The Ox-LDL was significantly lower after 3 and 6 months of febuxostat treatment compared with topiroxostat.Conclusion: Febuxostat had stronger renoprotective and antioxidant effects than topiroxostat in patients with hyperuricemia and CKD.

Background The aim of the present study was to evaluate the efficacy of α-human atrial natriuretic peptide (hANP) in cardiac surgery under cardiopulmonary bypass (CPB). Methods and Results A prospective randomized study was conducted with 150 patients who underwent scheduled coronary artery bypass grafting to compare a group of patients receiving 0.02 μg · kg-1 · min-1 of hANP from the initiation of CPB with a group not receiving hANP. Hemodynamics, levels of atrial and brain natriuretic peptides (BNP), angiotensin-II and aldosterone, renin activity, and left ventricular (LV) function were examined. The hANP group showed significantly lower renin activity and lower levels of angiotensin-II and aldosterone during the early postoperative period, compared with the non-hANP group. The incidence of postoperative ventricular arrhythmia and the postoperative peak level of creatine kinase-MB were significantly lower in the hANP group. BNP at 1 month after surgery and measures of LV function were also significantly lower in the hANP group. Conclusions Low-dose continuous infusion of hANP during cardiac surgery not only had a compensatory effect for the imperfections of CPB during the early postoperative period but also an inhibitory effect on postoperative LV remodeling and a reduction in ischemia/reperfusion injury. hANP should be part of the postoperative care for cardiac surgery.
