Objective. To determine the changes in liver function tests after long-term risperidone treatment in a child and adolescent population. Methods. Weight, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transpeptidase, alkaline phosphatase and serum bilirubin of the patients were assessed in pre-treatment period, and at the sixth and 12th months of treatment. One hundred children and adolescents (aged between 3 and 18 years) were enrolled to the study. Results. Liver enzyme and bilirubin levels are higher than normal in 21.0% of the patients without clinical symptoms. No cases of hepatic failure or jaundice were s . . .een. Only in an 8-year-old boy were there ALT level increases up to three-fold and AST level increases up to two-fold. After discontinuation of the risperidone treatment, enzyme levels were normalized in this patient. Alkaline phosphatase, alanine and aspartate aminotransferases were the most frequently increased enzymes. Conclusion. In this study, after long-term risperidone treatment of children and adolescents there was no evidence of clinically significant increases of liver enzymes and bilirubin levels. These results indicate that risperidone treatment may rarely cause serious liver enzyme increases, and may commonly cause clinically insignificant changes in liver function tests Daha fazlası Daha az

Objectives: Atypical antipsychotics (AAPs) have been reported to cause metabolic dysregulation that can cause AAPs-related weight gain. The purpose of this study was to assess triglyceride, cholesterol, and weight changes among risperidone-treated children and youths. Methods: Eighty-one subjects treated with risperidone for any psychiatric disturbances were included in the study. Fasting total low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglyceride (TG) levels were measured at the baseline and at the sixth month of treatment. Results: TG, TC and LDL-C level . . .s increased over time and reached statistical significance but there has been no change in HDL-C levels. Seven subjects (8.64%) crossed the threshold into clinically significant hypertriglyceridemia, four subjects (4.94%) crossed the threshold into clinically significant hypercholesterolemia, defined as going over the 95th percentile of published age normed plasma TG and TC levels, respectively. There was a positive correlation between TG and TC elevations and weight gain. There was no significant association with age, gender, diagnoses, risperidone dose and changes of serum TG, TC or LDL-C levels. Conclusion: The present study identified significant associations between lipid dysregulation and risperidone treatment. Since there is little research available on long-term lipid profile follow-up with atypical antipsychotics treatment in children and youths, controlled studies in larger samples should be carried out to reveal the relationship between risperidone use and plasma lipid parameters in the pediatric population. © 2011 Elsevier GmbH.

Objective: Revealing of unknown adverse effects of atypical antipsychotics on pediatric population may take a long period of time. The purpose of this prospective study is to document changes in the liver function tests (LFTs) associated with risperidone usage in a group of children and adolescents. Method: Study subjects consist of 120 youths with ages ranging from 3-17 years. For this study, patients' baseline and follow-up weight and hepatobiliary function tests including alanine aminotransferases(ALT) and aspartat aminotransferases (AST), gamma gluatamyl transerase (GGT), alkaline phosphatase (ALP) and serum bilirubin levels wer . . .e measured before and after the treatment period of one month. Results: Only one male patient's ALT levels increased up to three-fold and AST levels increased up to two-fold of the basal levels. First month mean levels of liver enzymes and billuribin of the patients were significantly higher than the baseline. Sixty-three patients (52.5%) showed an asymptomatic increase in the liver enzymes and/or billuribin levels of the first month of this study. Weight gain was observed in 58 patients (57.4%). There was no significant association between changes in weight and liver enzymes and billuribin levels. Conclusion: We found clinically non significant liver function test abnormalities mostly in the form of ALP elevation in 52.5% and marked liver enzymes elevation in 0.8% of risperidone-treated subjects. However use of concomitant medications and variations in age are the limitations of this study. These findings suggest that risperidone treatment in the short term may lead to liver function changes in children and adolescents. © 2008 Elsevier Inc. All rights reserved Daha fazlası Daha az

Objective: Atypical antipsychotics (AAPs) have been reported to cause metabolic dysregulation that may result in AAPs-related weight gain. The purpose of this study was to assess triglyceride, cholesterol and weight changes among risperidone-treated child and youths. Methods: Eighty subjects treated with risperidone for any psychiatric disturbances were included in the study. Fasting total low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol, (HDL-C), total cholesterol (TC), and triglyceride (TG) levels were measured at baseline and at 12 months of treatment. Results: There was no significant difference . . .between baseline mean levels of TG, TC, HDL-C and LDL-C and twelfth months mean levels of TG, TC, HDL-C and LDL-C (respectively p=0.341, p=0.135, p=0.414, p=0.411, p=0.707). Comparison of baseline and 12 months data with respect to the age groups were presented in table 2. There was no significant association with age, gender, risperidone dose and changes of serum T G, TC, LDL-C or HDL-C levels. Conclusion: In conclusion, this study did not identify significant associations between dyslipidemia and one year risperidone treatment in children and adolescents. Because little long-term lipid profile follow-up is available with atypical antipsychotics treatment in youths, controlled studies in larger samples should be carried out to reveal the frequency and the risk factors of dyslipidemia Daha fazlası Daha az

Objective: Atypical antipsychotic drugs commonly cause asymptomatic increase in the liver enzymes and serum bilirubin levels. However they rarely may induce a serious hepatic toxicity. In this article we aimed to evaluate the effect of atypical antipsychotic drugs namely olanzapine, risperidone and quetiapine on the hepatic enzymes and serum bilirubin levels in psychiatric patients. Method: Chart reviews of 312 patient followed-up at Psychiatry Department of Zonguldak Karaelmas University Hospital were examined in detail. The patients whose baseline and follow-up liver function tests including alanine aminotransfeaminotransferase (A . . .LT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphotase (ALP) and serum bilirubin that were measured before and within the treatment period of first and sixth months were enrolled. Forty eight males and 62 females whose ages ranging from 12 to 65 years were eligible for this study (no pregnant case was present). Results: The repartition according to treatment is as follows: olanzapine (n = 33), risperidone (n = 29), and quetiapine (n = 48). Two of the 110 patients (1.8%) presented with increased AST levels of up to 4 fold and ALT of thrice the basal level and needed to stop treatment (AST increase in one female with olanzapine 20 mg/day; ALT increase in one male with olanzapine 30 mg/day). Thirty of the 110 patients (27.2%) showed asymptomatic increases in ALT, AST, GGT and serum bilirubin levels in the first month of the study. After 6 months of the treatment, abnormalities in the liver function tests were observed in 25 patients (22.7%). Conclusion: These results were in accordance with previous studies that asymptomatic increase of liver enzymes are common but significant liver enzyme elevations are rare during atypical antipsychotic treatment. We suggest that obtaining baseline liver enzyme tests before atypical antipsychotic therapy and monitoring regularly specifically in patients with risk factors for liver damage during therapy. © 2007 Elsevier Inc.
