POPULATION:
Adult kidney transplant recipients with stable graft function (n= 247). INTERVENTION:Targeted haemoglobin of 11 to 12 g/dL with the use of erythropoietin-stimulating agents (ESA) (group 1, n= 183) COMPARISON:Targeted haemoglobin of 13 to 15 g/dL with ESA (group 2, n= 64) OUTCOME:Patients underwent monthly clinical and laboratory evaluations of kidney graft function. Quality of life and echocardiography were assessed at study start and at 12 months. In group 2, there were comparable post-transplant complications, but better graft function at 6 months and better cardiac indexes at 1 year of the study. At 12 months, quality of life had improved after full correction of post-transplant anaemia in the renal transplant recipients who received erythropoietin-stimulating agents.
OBJECTIVES:
Posttransplant anemia might be associated with cardiovascular morbidity and increased mortality. To our knowledge, the debate on anemia correction has neither been revisited nor decided definitively. We aimed to assess the effects of full correction of posttransplant anemia on the cardiovascular system and quality of life among renal transplant recipients with stable graft function who were using erythropoietin-stimulating agents. MATERIALS AND METHODS:We enrolled 247 kidney recipients with stable graft function to be assessed for anemia. Eligible patients were randomized to achieve targeted hemoglobin of 11 to 12 g/dL (group 1, n = 183) or of 13 to 15 g/dL (group 2, n = 64) with the use of erythropoietin-stimulating agents. Patients underwent monthly clinical and laboratory evaluations of kidney graft function. Quality of life and echocardiography were assessed at study start and at 12 months. RESULTS:The 2 groups were comparable regarding pretransplant characteristics. In group 2, we observed comparable posttransplant complications (P > .05) but better graft function at 6 months and better cardiac indexes at 1 year of the study (P < .05). At 12 months, quality of life had improved after full correction of posttransplant anemia in the renal transplant recipients who received erythropoietinstimulating agents. CONCLUSIONS:Full correction of posttransplant anemia in renal transplant recipients was associated with improved quality of life and cardiac indexes without an effect on cardiovascular comorbidity. |

POPULATION:
Patients undergoing liposculpture and/or abdominoplasty (n= 427). INTERVENTION:Presurgical and postsurgical tranexamic acid (TXA), (study group, n= 219). COMPARISON:Presurgical TXA (control group, n= 208). OUTCOME:Median postoperative haemoglobin levels at 24 hours were similar in both groups (study 11.3 g/dL versus control 11.1 g/dL). At 72 hours, postoperative haemoglobin was higher in the study group versus control (10.8 versus 10.0 g/dL). The incidence of transfusions at 72 hours was 1.8% in the study group and 8.6% in the control group, for a risk ratio of 0.21; 95% confidence interval [0.07, 0.61]. There were no adverse or thromboembolic events.
BACKGROUND:
Tranexamic acid (TXA) is used to reduce bleeding in body contouring procedures; however, there are no studies that show the effectiveness of TXA when it is also used in the immediate postoperative period. METHODS:A controlled, randomized, parallel, and open-label clinical trial was carried out in adult patients undergoing liposculpture and/or abdominoplasty. A control group administering presurgical TXA and a study group with presurgical and postsurgical TXA were formed. The decrease in hemoglobin and the incidence of blood transfusions between both groups were compared as well as the possible adverse effects of TXA. RESULTS:Four hundred twenty-seven subjects were included, 208 (48.7%) in the control group and 219 (51.3%) in the study group. The median age was 34 years (interquartile range 28-42). Median postoperative hemoglobin levels at 24 hours were similar in both groups (study 11.3 g/dL versus control 11.1 g/dL, P = 0.07); however, at 72 hours, postoperative hemoglobin was higher in the study group versus control (10.8 versus 10.0 g/dL, P ≤ 0.001). The incidence of transfusions at 72 hours was 1.8% in the study group and 8.6% in the control group, for a risk ratio of 0.21 (95% confidence interval 0.07-0.61). There were no adverse or thromboembolic events. CONCLUSION:TXA proved to be more effective in reducing intra- and postsurgical bleeding and the need for transfusions, when used preoperatively and continued for 48 hours after surgery, than when used only preoperatively, without reporting adverse or thromboembolic effects. |
