Valproate, weight gain and carbohydrate craving: a gender study.

PURPOSE: To compare the incidence and magnitude of weight gain associated with valproic acid (VPA) monotherapy in male and female epilepsy patients and to determine possible gender-specific differences in frequency of carbohydrate craving, body-composition, glucose homeostasis and lipid metabolism. METHODS: Epilepsy patients on VPA monotherapy were consecutively recruited at the outpatient clinic of the Department of Neurology, Innsbruck Medical University. Weight gain during VPA-therapy, frequency of carbohydrate craving and physical exercise, sociopsychological problems and family history for diabetes were obtained from all patients. Clinical data also comprised body-impedance analysis, body mass index and waist-to-hip ratio. Morning fasting blood samples were drawn to determine serum leptin, glucose and lipid concentrations, as well as insulin, C-reactive protein and TNF-alpha. RESULTS: One hundred and six patients (55 women) were enrolled in the study. Significant weight gain was seen during VPA-therapy in both genders (each p<0.001) with women experiencing increment of weight more frequently and more pronounced than did men. Analyses of patients who gained weight during VPA-therapy revealed significantly higher serum leptin concentrations in women than in men (p<0.001). Women also revealed significantly higher high-density lipoprotein-cholesterol and lower triglyceride concentrations than men (p=0.004 and 0.014, respectively). Frequency of carbohydrate craving was 25.8% in women and 14.3% in men. More women tried to lose or control weight through diet than did men (22.6% versus 7.1%). Moreover, weight gain as a sociopsychological problem was more numorous in women than in men. CONCLUSION: Women are more prone to gain weight during VPA therapy though higher frequency of diet and sociopsychological burden than men, which might possibly be related to leptin-resitance and a higher frequency of carbohydrate craving.

Alterations of glucose metabolism during treatment with clozapine or amisulpride: results from a prospective 16-week study.

Although second-generation antipsychotics have notable benefits as compared to typical antipsychotics, their use has been associated with metabolic disturbances, such as alterations of glucose homeostasis. It is still being debated whether this is a class effect of second-generation antipsychotics. We conducted a prospective, open study comparing body weight, parameters of insulin resistance in schizophrenia patients treated with either clozapine (n = 10) or amisuLpride ( n = 12). All parameters were assessed monthly over a period of 12 to 16 weeks. Body mass index (BMI), fasting serum insulin levels and the Homeostasis Model Assessment (HOMA) index for insulin resistance increased significantly in patients treated with clozapine. None of these parameters increased significantly in patients treated with amisulpride. This study indicates that treatment with clozapine appears to have a higher risk to lead to metabolic disturbances than amisupride.

Early changes of plasma lipids during treatment with atypical antipsychotics.

Metabolic side effects have been found earlier during treatment with second-generation antipsychotics. Among those disturbances serum lipids are less investigated. We conducted a prospective, open study in schizophrenia patients in order to compare body weight and serum lipids during treatment with amisulpride, ziprasidone, clozapine or olanzapine over a period of 4 weeks. Body mass index, total cholesterol and triglycerides increased in patients treated with clozapine and olanzapine whereas high-density lipoprotein cholesterol decreased in those patients. In patients treated with amisulpride or ziprasidone, we found a decrease in body mass index and total cholesterol whereas high-density lipoprotein cholesterol increased. Our results indicate that treatment with ziprasidone and amisulpride is more favourable than treatment with clozapine and olanzapine with respect to the risk to induce weight gain and hyperlipidaemia. These results are important with regard to the increased risk for cardiovascular complications in patients with schizophrenia.

Insulin glargine in combination with oral antidiabetic drugs as a cost-equivalent alternative to conventional insulin therapy in type 2 diabetes mellitus.

BACKGROUND AND RATIONALE: Recent data suggest that insulin glargine might be a cost-effective alternative to conventional insulin therapy in patients with type 2 diabetes mellitus (T2DM). The aim of this observational study was to evaluate the treatment costs of insulin glargine in combination with oral antidiabetic drugs (OADs) compared with conventional insulin therapy in T2DM in everyday clinical practice. PATIENTS AND METHODS: Data were obtained from a cohort of 678 patients with T2DM not adequately controlled by OADs alone (HbA1c mean 9.1 +/- 1.7%). Patients received either insulin glargine in addition to oral therapy or were switched to conventional insulin therapy. Treatment and dosing decisions were made at the physician's discretion, reflecting everyday practice. Patients were followed for 2-4 months. Primary outcome parameters were total treatment costs and clinical efficacy. RESULTS: The two therapeutic regimens were equally effective in decreasing HbA1c to 7.8% (p < 10(-9)). Patients in the insulin glargine plus OAD group controlled their blood glucose level at endpoint with a median of 60 test strips per month and those in the conventional insulin therapy group with a median of 80 strips per month (p = 0.000000739). Total daily costs of insulin, needles, glycemic control and OAD treatment per patient were similar in the two treatment groups (insulin glargine group 1.91 Euro vs conventional group 1.99 Euro). CONCLUSION: The two treatment regimens were equally effective in improving glycemic control. These results were achieved with significantly lower insulin doses and fewer blood glucose test strips in the insulin glargine group, which therefore led to cost equivalence when compared with conventional insulin therapy.

Valproate therapy and nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease was defined recently as another symptom of insulin resistance. Continuous therapy with valproate can result in increased body weight and insulin resistance, but no data are yet available on a possible relationship between valproate and nonalcoholic fatty liver disease. We here demonstrate in abdominal ultrasound investigations that characteristics of fatty liver disease were present in 61% of valproate-treated patients as compared with 23% receiving carbamazepine therapy.

[Pathogenesis of obesity].

During the last years various studies have been able to offer an insight into the regulation of appetite, satiety and energy balance, as well as adipocyte differentiation and the role of adipose tissue as an endocrine organ. These mechanisms add new aspects to the pathogenesis of obesity, but also to the development of weight-reducing medications. Life-style factors, including reduced physical exercise and a high calorie intake, are responsible for the increase in obesity in industrialized countries. As a result of twin and adoption studies, the genetic influence on the development of obesity is estimated to be 30-70%. As regards the common form of obesity, more than 70 gene loci have been described as possible candidate genes. These comprise genes involved in central nervous regulation systems, including leptin, the leptinreceptor, POMC, MCR-4, as well as energy expenditure and adipocyte differentiation such as beta-adrenergic receptors, UCPs, and the nuclear receptor PPARy. The common form of obesity seems to be mainly due to an interaction between genetic disposition and environmental factors.

[Mitochondrial function--role in insulin resistance and lipid metabolism].

Risk factors for the development of type 2 diabetes mellitus, including weight gain, lack of physical exercise and increasing age, are associated with an impaired mitochondrial function. Clinical studies could demonstrate a reduced mitochondrial activity in non-diabetic but insulin-resistant offsprings of type 2 diabetics. A key enzyme in the regulation of cellular energy supply and thus also in glucose and lipid metabolism is AMP-activated proteinkinase (AMPK). Pharmacological substances, which stimulate AMPK-activity ameliorate insulin resistance induced by free fatty acids. Various therapeutical interventions for the improvement of insulin sensitivity, including weight loss, physical exercise, as well as metformin and glitazones, increase AMPK activity.
