Apolipoprotein E in Southern Italy: protective effect of epsilon 2 allele in early- and late-onset sporadic Alzheimer's disease.

Apolipoprotein E (apoE) polymorphism was evaluated in 81 sporadic late onset Alzheimer's disease (LOAD) patients, 28 sporadic early-onset Alzheimer's disease (EOAD) and 92 sex- and age-matched healthy controls from Apulia, Southern Italy. ApoE genotypes were determined by the polymerase chain reaction-restriction fragment length polymorphism method. The frequency of apoE epsilon 4 allele was significantly higher in EOAD patients than in the control group, but not in LOAD patients. Furthermore, EOAD patients carrying epsilon 4 allele had lower age at onset of AD symptoms (about 4. 5 years). In the whole sample, epsilon 4 was associated to AD by an odds ratio of 2.14, while it increased up to 6.55 in < 65 years old subjects. Finally, in both < 65 and > or = 65 subgroups of subjects, epsilon 2 played a protective role against the development of AD. It is concluded that the geographic decreasing trend of epsilon 4 allele and the age at onset may influence the association of apoE polymorphism with sporadic AD in a Southern Italian sample.

[Age-related cognitive decline: evaluation and prevention strategy].

The age-related decline of cognitive functions generally refers to a mild deterioration in memory performance, executive functions, and speed of cognitive processing. The terms "age-related cognitive decline" (ARCD) and "aging-associated cognitive decline" have been proposed recently to indicate an objective decline in cognitive functioning associated to the ageing process but within normal limits given the person's age. Whether ARCD is expression of a normal ageing process or represents a distinct clinical entity or, eventually, is a continuum with dementia is, at present, difficult to establish. The causes of ARCD are unknown, but some studies have suggested that it may be prevented. Avoidance of cardiovascular and other chronic diseases, high educational level, and maintenance of vision and hearing have been identified as protective factors from ARCD. On the contrary, hypertension, effects of altered metabolism of steroid hormones, smoking, low-complexity occupation, higher density of persons/bedroom in home, and low level of physical activity have been identified as risk factors for ARCD. Recent findings suggest a possible role of diet in the ARCD. In fact, in an elderly population of Southern Italy with a typical Mediterranean diet, high monounsaturated fatty acids energy intake appeared to be associated with a high protection against cognitive decline. Dietary antioxidants, specific macronutrients, estrogens, and anti-inflammatory drugs, may act synergistically with other protective factors, opening new therapeutic interventions for cognitive decline.

Decreased frequency of apolipoprotein E epsilon4 allele from Northern to Southern Europe in Alzheimer's disease patients and centenarians.

Apolipoprotein E (apoE) polymorphism was studied in 79 sporadic late onset Alzheimer's disease (LOAD) patients, 125 unrelated caregivers or volunteers (19-80 years), and 67 centenarians from Apulia, Southern Italy. The frequency of apoE epsilon2 allele was higher in centenarians than in LOAD patients, while epsilon4 was lower. In middle-aged adults, the epsilon4 allele frequency was higher than in centenarians. The epsilon4 allele frequency was lower in healthy adults than in LOAD patients, while epsilon2 was higher. Compared with the allele frequencies of Northern and Central European countries, a geographic trend for epsilon3 and epsilon4 alleles in LOAD and middle-aged adults was observed. The frequency of epsilon3 increased from Northern to Southern Europe, while epsilon4 decreased significantly. In centenarians, epsilon2 showed a North-South increasing pattern, while epsilon4 was in opposite trend.

High monounsaturated fatty acids intake protects against age-related cognitive decline.

OBJECTIVE: To study the relationships between dietary macronutrient intakes and age-related changes in cognitive functions. METHODS: We investigated these associations in the prevalence survey (1992 through 1993) of the Italian Longitudinal Study on Aging (ILSA). The population-based sample of 5,632 subjects of the ILSA, age 65 to 84 years, was identified from the electoral rolls of eight Italian municipalities. In this study, standardized test batteries assessing global cognitive functions (Mini-Mental State Examination [MMSE]), selective attention (Digit Cancellation Test [DCT]), and episodic memory (Babcock Story Recall Test), and a semi-quantitative food frequency questionnaire evaluating macronutrient energy intakes, were performed on 278 nondemented elderly subjects from the randomized cohort of Casamassima, Bari (n = 704). RESULTS: There was an inverse relationship between monounsaturated fatty acids (MUFAs) energy intake and cognitive decline (MMSE < 24). The effect of education on the odds of having a MMSE score <24 decreased exponentially with the increase of MUFA intakes (over 2,400 kJ; odds ratio, 0.69). Moreover, a significant inverse association was observed between MUFA intakes and DCT score (odds ratio, 0.99). No association was found between nutritional variables and episodic memory. CONCLUSIONS: In an elderly population of Southern Italy with a typical Mediterranean diet, high MUFA intakes appeared to be protective against age-related cognitive decline. Prospective clinical trials are needed to evaluate the impact of specific dietary macronutrient intakes on the age-related changes of cognitive functions.

Increased bile acid excretion and reduction of serum cholesterol after crenotherapy with salt-rich mineral water.

The effect of a spring mineral water from Montecatini (Italy) on bile acid excretion, and lipid and apolipoprotein serum levels was evaluated. The study was conducted in subjects with serum total cholesterol (TC) level > 240 mg/dL and LDL cholesterol (LDL-C) > 170 mg/dL, over a 9-week period, with 3 weeks of dietary stabilization, 3 weeks of active treatment, and 3 weeks of tap-water treatment as a control period. Serum lipids and apolipoproteins, total and fractionated bile acid excretion, gallbladder motility, and safety parameters were evaluated. Active treatment with mineral water significantly reduced serum TC by 7.5%, LDL-C by 12.5%, TC/HDL-cholesterol ratio by 6.3%, and apolipoprotein B by 6.3%; total fecal bile acid excretion was increased by 98.9%, and gallbladder volume was reduced by 40%. The reduction in serum and LDL-cholesterol levels observed during the active treatment period ran parallel to the increased excretion of bile acids in the stools. We suggest that salt-rich spring water treatment reduces serum and LDL-cholesterol levels in subjects with mild hypercholesterolemia through a mechanism of increased excretion of fecal bile acid sterols.
