Interleukin-1 alpha and beta, TNF-alpha and HTTLPR gene variants study on alcohol toxicity and detoxification outcome.

Genetic factors may influence the liability to treatment outcome and medical complications in alcoholism. In the present study we investigated the IL-1A rs1800587, IL-1B rs3087258, TNF-alpha rs1799724 and the HTTLPR variants in a sample of 64 alcohol dependents and 47 relatives versus a set of clinical parameters and outcome measures. Alcohol dependents had a less favorable clinical profile compared to relatives (higher cholesterol, triglycerides, glucose, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, gamma-glutamyltransferase). After detoxification, all clinical indexes improved and hepatic enzyme levels were similar in alcohol dependents and relatives, except for the GGT that remained significantly higher in alcohol dependents. Alcoholic depressive and anxiety scores were significantly reduced after detoxification. IL-1A, IL-1B, TNF-alpha and HTTLPR variants were not associated with any baseline clinical index or change after detoxification. In our sample IL-1A, IL-1B, TNF-alpha and HTTLPR do not appear as liability factors for alcohol toxicity or detoxification outcome, however the small sample size may influence the observed results.

Differences in expression of cardiovascular risk factors among type 2 diabetes mellitus patients of different age.

Atherosclerotic coronary heart disease and other forms of cardiovascular disease (CVD) are the major cause of mortality in type II diabetes (T2DM) as well as a major contributor to morbidity and lifetime costs. The purpose of this article is the identification of the biochemical parameters in plasma, which may serve as predisposition factors to CVD in T2DM patients of different ages. The variability of hyperglycemia, dyslipidemia, and inflammation with age progression was also studied for comparison. Four different diabetic groups allocated on the basis of the subjects' age (Group A: 15-25 years old; Group B: 26-40 years old; Group C: 40-60 years old; Group D: 60-80 years old) and consisting of 10 patients each, in parallel with 10 healthy controls matched for age, sex, and ethnic origin were screened for glucose, insulin, lipid profile (total cholesterol, triglycerides, LDL, and HDL), and inflammatory mediators (CRP, IL-6, and TNF-alpha). Significant differences were observed among the expressions of biochemical markers among different age groups. Hyperglycemia showed no variability with age whereas dyslipidemia correlated positively with age progression, as well as obesity, low physical activity, and family history of heart disease or diabetes. Marked inflammation was prominent only in Groups C and D. This article indicates that different biochemical parameters may be used for the assessment of CVD risk in T2DM patients of variable age.

Interrelationship of hepatic function, thyroid activity and mood status in alcohol-dependent individuals.

BACKGROUND: Alcohol-induced changes in thyroid function may contribute to the development of mood disorders such as depression and anxiety that almost invariably coexist in alcohol-dependent individuals. The aim of the present study was to investigate the severity of liver dysfunction and thyroid activity in correlation with anxiety and depressive-like symptomatology before and after a detoxification period. PATIENTS AND METHODS: In a sample of 100 alcohol-abusing/dependent subjects treated on an in-patient basis according to a standard detoxification protocol, measurements of the serum levels of hepatic enzymes (ASAT, ALAT, gammaGT) and thyroid hormones (T3, T4, TSH) as well as measures of anxiety, depression and global functioning were obtained at baseline and at weekly intervals over the period of 4-5 weeks. RESULTS: After completion of the alcohol detoxification, most measurements returned to normal levels and correlations were observed between the levels of hepatic enzymes and thyroid hormones. Additionally, a significant correlation was obtained between the levels of thyroid hormones and the mood status scales. CONCLUSION: Our results indicated a dysfunction of the hypothalamic-pituitary-thyroid axis in alcohol dependence with possible implications in the diagnosis and treatment of mood disorders associated with alcohol abuse.
