Clinical trial of levocarnitine on patients with continuous blood purification
Objective To evaluate the clinical effect of levocarnitine in the treatment of continuous blood purification and its effect on matrix metalloproteinase-2(MMP-2),interleukin-18(IL-18)and heart function.Methods 118 patients with continuous blood purification were randomly divided into the control group(n=59)and treatment group group(n=59).Two groups were treated with hemodialysis treatment.Control group was given folic acid,vitamin B and alpha keto acid,treatment group intravenous given levocarnitine injection 20mg/kg+0.9%NaCl 20mL on the basis of control group.A cycle of treatment was 28 days,and treated for 3 cycles.Serum levels of MMP-2 and IL-18,heart function,clinical effect and adverse drug reaction were compared between the two groups.Results After treatment,the total effective rate in control group was 84.74%,lower than 94.92%in treatment group(P<0.05).After treatment,serum MMP-2,IL-18,left atrial diameter(LAD),left ventricular end diastolic diameter(LVDd),left ventricular posterior wall thickness(LVPWT),ventricular septal thickness(IVST),left ventricular volume index(LVMI)in two groups were lower than pre-treatment(P<0.05),and the indexes in treatment group were more lower than control group(P<0.05).The E/A and left ventricular ejection fraction(LVEF)in two groups were all increased after treatment,and those in treatment group were higher than control group,the differences were significant(P<0.05).There was no significant in the incidence rate of adverse drug reactions between two groups.Conclusion Levocarnitine in the treatment of continuous blood purification was effective,and significantly reduce the serum MMP-2,IL-18 level and improve the heart function.
