Safety Assessment of Liver Injury with Quetiapine Fumarate XR Management in Very Heavy Drinking Alcohol-Dependent Patients.

ABSTRACT: BACKGROUND:Studies have reported liver injury as a consequence of antipsychotic treatment. Very heavy alcohol drinking (ten or more drinks/day for men and eight for women) also causes liver injury. This study aims to evaluate liver injury with quetiapine extended release (XR) in very heavy drinking alcohol-dependent (AD) patients. METHODS:Two hundred and eighteen AD patients, 18-65 years of age, received 12 weeks of quetiapine XR or placebo treatment in a dose-escalated manner reaching the full dose of 400 mg/day during week 4. Blood chemistry and hematology were assessed at baseline (W0), post-titration at the end of week 3 (W4), week 8 (W8), and end of week 12 (W13). Patients were further grouped as GR.1 (no liver injury, ALT ?40) and GR.2 (pre-existing liver injury, ALT >40) within each treatment. Drinking history, fasting blood glucose concentration (FBG), and lipid panel were used as covariates in the analyses. RESULTS:Liver injury and total drinks and average drinking measures from the Timeline follow-back questionnaire (TLFB) were highly associated. No significant exacerbation in liver injury was observed in patients treated with quetiapine XR in GR.2. Liver injury as determined by elevated alanine aminotransaminase (ALT) was reported in a few patients in GR.1 who received quetiapine XR; however, the occurrence was low, and the level of liver injury was not significant. FBG and lipid measures showed some elevation, but did not show any significant association with liver injury. CONCLUSION:Quetiapine XR did not show any significant exacerbation of liver injury in very heavy drinking alcohol-dependent patients with pre-existing liver injury. Frequency and severity of new liver injury cases in quetiapine XR-treated patients without any pre-existing liver injury was also low. Study findings support medical management of AD patients with heavy drinking profile using quetiapine XR formulation.

Project description:OBJECTIVES:To evaluate the efficacy and tolerability of once-daily extended release quetiapine fumarate (quetiapine XR) monotherapy in patients with major depressive disorder (MDD). PATIENTS AND METHODS:This was a 10-week (8-week active treatment/2-week post-treatment) randomized, double-blind, placebo- and active-controlled study (D1448C00004). Patients received quetiapine XR 150 mg/day, escitalopram 10 mg/day, or placebo; patients with an inadequate response (<20% improvement in Montgomery-Åsberg Depression Rating Scale [MADRS] total score) at week two received double-dose treatment. The primary end point was week eight change from randomization in MADRS total score. Secondary end points included MADRS response (?50% improvement) and remission (score ?8); Hamilton Rating Scale for Depression total and item 1; Hamilton Rating Scale for Anxiety total, psychic, and somatic; Clinical Global Impressions - Severity of Illness total; Pittsburgh Sleep Quality Index (PSQI) global; and Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form percentage maximum total scores. Tolerability was assessed throughout. RESULTS:A total of 471 patients was randomized. No significant improvements in MADRS total score were observed at week eight (last observation carried forward) with either active treatment (quetiapine XR, -17.21 [P=0.174]; escitalopram, -16.73 [P=0.346]) versus placebo (-15.61). There were no significant differences in secondary end points versus placebo, with the exception of week-eight change in PSQI global score (quetiapine XR, -4.96 [P<0.01] versus placebo, -3.37). Mixed-model repeated-measures analysis of observed-case data suggested that the primary analysis may not be robust. Most commonly reported adverse events included dry mouth, somnolence, and dizziness for quetiapine XR, and headache and nausea for escitalopram. CONCLUSION:In this study, neither quetiapine XR (150/300 mg/day) nor escitalopram (10/20 mg/day) showed significant separation from placebo. Both compounds have been shown previously to be effective in the treatment of MDD; possible reasons for this failed study are discussed. Quetiapine XR was generally well tolerated, with a profile similar to that reported previously.

Project description:BackgroundHeavy alcohol consumption frequently causes liver inflammation/injury, and certain fatty acids (FAs) may be involved in this liver pathology. In this study, we evaluated the association of heavy drinking and the changes in the FA levels involved in the ω-6 (pro-inflammatory) and ω-3 (anti-inflammatory) state in alcohol-dependent (AD) patients who had no clinical manifestations of liver injury. We aimed to identify sex-based differences in patients with mild or no biochemical evidence of liver injury induced by heavy drinking.MethodsA total of 114 heavy drinking AD female and male patients aged 21 to 65 years without clinical manifestations of liver injury, who were admitted to an alcohol dependence treatment program, were grouped by the alanine aminotransferase (ALT) levels: ≤40 IU/l, as no liver injury (GR.1), and >40 IU/l, as mild liver injury (GR.2). Patients were actively drinking until the day of admission. Comprehensive metabolic panel, comprehensive FA panel, and drinking history data were evaluated.ResultsElevated ALT and aspartate aminotransferase (AST) showed close association with markers of heavy alcohol intake. In the patients with mild biochemical liver injury (GR.2), females showed significantly higher AST level than males. Significant association of AST and total drinks in past 90 days (TD90) in females, and AST and heavy drinking days in past 90 days (HDD90) in males was observed. The ω-6:ω-3 ratio showed a significant pro-inflammatory response only in females with mild liver injury (GR.2) when adjusted by drinking history marker, TD90. Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were increased in males with liver injury, while females did not show any comparable rise in EPA; and DHA levels were lower.ConclusionsMeasures of heavy drinking, TD90 and HDD90, predicted changes in liver injury. Changes in the ω-3 and ω-6 FA levels and the ω-6:ω-3 ratio showed a pro-inflammatory shift in patients with biochemical liver injury with a significant effect in females. Changes in FAs involved in the inflammatory state may represent one mechanism for liver inflammation/injury in response to heavy alcohol drinking.

Project description:BackgroundMost physiological studies interested in alcohol-dependence examined ethanol as a pharmacological agent rather than a nutrient. We conducted two studies, which assessed the metabolic and endocrine factors involved in the regulation of alcohol and nutrient intake in alcohol-dependent (AD) subjects. We also examined the potential role of a disruption in energy balance in alcohol-dependence.Methods and resultsIn Study-1, quantitative dietetic interviews of eating and drinking habits were conducted with 97 AD subjects. The population was split around a median alcohol intake value of 12.5 kcal/kg/day. The results showed that the "low alcohol" drinking AD subjects had high Body Mass Index (BMI) and Fat Mass (FM) and alcohol intake was compensated for by a decrease in non-alcoholic intakes. "High alcohol" drinking AD subjects, on the other hand, had low BMI and FM and the total caloric intakes were largely above norms. In Study-2, 24 AD inpatients were submitted to dietetic interviews, calorimetry and blood samplings for the measurement of biomarkers of the regulation of metabolism and satiety, on day 2, 5 and 16 of abstinence. These patients were compared with 20 controls matched for age and gender. We observed in AD patients an increase in cortisol, leptin and PYY plasma levels and a decrease in ghrelin, which might explain the observed decrease in non-alcoholic intakes. However, alcoholic and non-alcoholic intakes correlated positively with basal metabolism and negatively with leptin and leptin/BMI.ConclusionFor individuals consuming below 12.5 kcal/kg/day of alcohol, alcohol intake is compensated for by a decrease in non-alcoholic nutrient intakes, probably due to changes in metabolic and satiety factors. For individuals consuming above 12.5 kcal/kg/day of alcohol, alcohol accelerates metabolism and decreases fat mass and leptin levels, and the total caloric intake largely exceeds norms. A dual model for regulation of energy intake in AD subjects is proposed.
