ABSTRACT

OBJECTIVE: To determine the efficacy of various antioxidant vitamins and a major dietary source of antioxidants (fruits) we performed a randomized controlled trial. METHODS: 175 successive patients with coronary heart disease (CHD) presenting to our centre were recruited and using a Latin-square design divided into five groups of 35 each. The groups were matched for age, lifestyle and dietary variables, clinical diagnosis and drug treatment status. None of the patients was on lipid-lowering drugs. Supplemental vitamins were stopped for one month before study began and American Heart Association Step II dietary advice was given to all. At baseline, total cholesterol, triglycerides, HDL and LDL cholesterol and lipid peroxide measured as thiobarbaturic acid reactive substances (TBARS) were determined. Group I received placebo capsules; Group II vitamin E 400 units/day; Group III vitamin C 1,000 mg; Group IV vitamin A 25,000 IU; Group V received 400 gm of fruit daily. Lipids and lipid peroxide levels were determined at 30 days follow-up. RESULTS: Response rate in various groups varied form 86% to 91%. No significant changes in total, HDL, LDL cholesterol and triglyceride levels were seen in Groups I, II, III and IV (paired t-test p > 0.05). In Group V there was a significant decrease in total cholesterol (-7.8 +/- 11.1%), and LDL cholesterol (-11.2 +/- 25.4%) and increase in HDL cholesterol (+12.9 +/- 20.1%) (paired t-test p < 0.01). Lipid peroxide levels decreased significantly in all the treatment groups (p < 0.01). This decrease was the highest in Group II (vitamin E; -36.4 +/- 17.7%) as compared to Group III (vitamin C -19.8 -/+ 10.8%); Group IV (vitamin A -5.4 +/- 17%) and Group V (fruits -13.1 +/- 12.0%). CONCLUSIONS: All the antioxidant vitamins and fruits significantly decrease lipid peroxide levels and oxidant load in CHD patients. However, fruits are the best choice as they also favourably modify the lipid profile.

ABSTRACT

Introducción. El sabor salado del suero oral (SO) puede limitar su uso. Objetivo: conocer la preferencia por varios sabores de frutas del SO: manzana, limón, naranja, piña o lima-limón y evaluar su eficacia para rehidratar niños con diarrea. Material y métodos. Cincuenta madres escogieron libremente el sabor. Posteriormente se distribuyeron al azar en 2 grupos, 230 niños deshidratados por diarrea, rehidratados con SO de sabor salado (SO) o con SO con sabor a diferentes frutas (SOF).Resultados. La preferencia de sabor fue: manzana 68 por ciento, limón 14 por ciento, piña 8 por ciento, naranja 8 por ciento, sin sabor 2 por ciento y lima-limón 0 por ciento. En el grupo SO y SOF fueron semejantes: la edad de los niños (10.5 ñ 8.2 y 11.1 ñ 7.2 meses), el porcentaje de deshidratación (3.9 ñ 2.6 y 4.2 ñ 2.4) y de sexo masculino (62 y 54 por ciento), respectivamente; al igual que la evolución con el tratamiento: ingesta de 21.8 ñ 5.6 y 20.9 ñ 5.1 mL/kg/hora, tiempo de hidratación 5.1 ñ 2.7 y 4.9 ñ 2.3 horas; gasto fecal 10.5 ñ 8.2 y 9.3 ñ 8.2 g/kg/hora, proporción de pacientes con vómitos 28 y 34 por ciento, respectivamente. Con el sabor naranja se observó la mayor proporción de vómitos (53 por ciento). En el grupo SO se observaron 15 fracasos (13 por ciento), 14 por gasto fecal alto y 1 por vómito persistente; en el grupo SOF, hubieron 13 fracasos (11.3 por ciento) 12 por gasto fecal alto y 1 por vómito persistente, aunque finalmente todos se hidrataron mediante el uso de atole de arroz o de gastroclisis. Conclusión. El SOF es igualmente aceptado, efectivo y seguro que el SO, en niños deshidratados por diarrea. El sabor preferido fue el de manzana y el que se asoció con más vómitos, el de naranja.
