No effect of atypical antipsychotic drugs on weight gain and risk of developing type II diabetes or lipid abnormalities among nursing home elderly patients with Alzheimer's disease.

AIM: Weight gain and the risk of developing alterations in lipid and glucose metabolism are possible side effects of atypical antipsychotic therapy in young and adult patients. The objective of this study was to examine whether elderly patients with Alzheimer's disease (AD) gain weight or develop disturbances in lipid and glucose metabolism while being treated with atypical antipsychotic drugs. METHODS: This retrospective study identified 36 out of 99 patients (mean age: 75.4+/-7.1, 27 female, 9 males) who were taking risperidone (N=9, mean dosage: 1.42+/-0.49 mg/day), olanzapine (N=17: 4.42+/-1.10 mg/day), and quetiapine (N=10: 75+/-27 mg/day) over a 12 months period. Anthropometric parameters, mini nutritional assessment (MNA), total, HDL and LDL cholesterol, triglycerides, glycaemia were assessed at baseline (T0) and 12 (T1) months. RESULTS: Body weight (BMI=23+/-5 vs 23+/-5), MNA score (21+/-4 vs 21+/-4), blood glucose (5.7+/-2 vs 4.9+/-0.9 mmol/L) or total cholesterol (4.9+/-1.1 vs 4.3+/-0.7 mmol/L), HDL cholesterol (1.3+/-0.3 vs 1.1+/-0.3 mmol/L), LDL cholesterol (3.3+/-0.7 vs 3 +/- 0.4 mmol/L), triglycerides (1.1+/-0 vs 1+/-0.3 mmol/L) did not reveal treatment-induced changes in the patients evaluated (T0 vs T1). CONCLUSION: These results suggest that the treatment with low-dose of atypical antipsychotic drugs is not associated with weight gain or increase the risk of developing type II diabetes or abnormalities of lipid metabolism among elderly patients with AD, who were residing in long-term nursing home.

[Food intake and nutritional status in a group of healthy elderly residing in a nursing home]. / Valutazione dello stato di nutrizione e degli intake alimentari in un gruppo di anziani autosufficienti residenti in una residenza sanitaria assistenziale.

BACKGROUND: Aging is accompanied by a variety of economic, psychologic, and social changes that can compromise the nutritional status. Nutrition is an important aspect of healthful behaviour and a major component of general wellbeing of individuals throughout their life cycle. Nutritional intake appears to be an important factor contributing to aging. So, the purpose of this project was to evaluate diet and nutritional status. METHODS: Fifty-one healthy elderly subjects aged 70 years and older (31 F and 20 M), residing in a nursing home have been studied. Nutrient intake was assessed using 24-hour recalls; nutritional status was assessed using anthropometric measurements. The nutrient intakes for individuals were compared with the Italian Recommended Dietary Allowances (RDAs). RESULTS: Mean energy intake was 1,625 kcal; the average percentages of carbohydrate, protein, and fat were 54%, 16%, and 30%, respectively. The mean vitamin and mineral intake for participants met the RDAs except for calcium and selenium intakes. The mean fibre intake was low. The analysis of food products intake indicated that the above mentioned inadequacy in nutrient intake was the result of low consumption of milk and milk products containing calcium and a low consumption of integral foods or fruits containing fibre. CONCLUSIONS: The significance of sound nutrition education and the adverse impact of consumer misinformation about the benefits of these food choices becomes clear with the recognition that nutritional status influences the rate of physiologic and functional declines with age. This approach will require new efforts in consumer education sensitive to the needs and beliefs of older people.

In vitro experiments were performed in order to clarify the influence of phenytoin on human granulocyte and platelet function. Therapeutic anticonvulsant concentrations of the drug significantly reduced the granulocyte aggregation produced by formyl-methionyl-leucyl-phenilalanine; phytoemoaglutinin-induced granulocyte aggregation was unaffected by phenytoin. In the same range of concentrations the drug was able to inhibit ADP-, epinephrine- and collagen-induced platelet aggregation. The possible in vivo implications of these data are discussed.
