El consumo de probiótico Lactobacillus plantarum CECT 7315/7316 mejora el estado de salud general en personas de edad avanzada
Fundamentos: Con la edad avanzada se producen cambios en la microflora intestinal que pueden afectar al estado de salud general. En este trabajo analizamos el efecto de Lactobacillus plantarum CECT 7315/7316 sobre la regulación del tránsito intestinal y el estado nutricional. Métodos: Hemos realizado un estudio clínico dobleciego, controlado por placebo y aleatorizado. Hemos evaluado la evolución de la frecuencia de defecación semanal y los niveles en sangre de proteínas totales, albúmina,colesterol y proteína C-reactiva. Resultados: Lactobacillus plantarum CECT 7315/7316 ayuda a regular el tránsito intestinal y mejora el estado nutricional en personas mayores. Conclusiones: El consumo de productos funcionales que contengan L. plantarum CECT 7315/7316 mejora la calidad de vida de personas de la tercera edad
Effect of the Degree of Polymerization of Fructans on Ex Vivo Fermented Human Gut Microbiome
Prebiotic supplements are used to promote gastrointestinal health by stimulating beneficial bacteria. The aim of this study was to compare the potential prebiotic effects of fructans with increasing degrees of polymerization, namely fructooligosaccharides (FOS) and inulins with a low and high polymerization degree (LPDI and HPDI, respectively), using an ex vivo fermentation system to simulate the colonic environment. The system was inoculated with pooled feces from three healthy donors with the same baseline enterotype. Changes in microbiota composition were measured by 16S metagenomic sequencing after 2, 7, and 14 days of fermentation, and acid production was measured throughout the experiment. Alpha-diversity decreased upon inoculation of the ex vivo fermentation under all treatments. Composition changed significantly across both treatments and time (ANOSIM p < 0.005 for both factors). HPDI and LPDI seemed to be similar to each other regarding composition and acidification activity, but different from the control and FOS. FOS differed from the control in terms of composition but not acidification. HDPI restored alpha-diversity on day 14 as compared to the control (Bonferroni p < 0.05). In conclusion, the prebiotic activity of fructans appears to depend on the degree of polymerization, with LPDI and especially HPDI having a greater effect than FOS
Lactobacillus plantarum CECT7315 and CECT7316 stimulate immunoglobulin production after influenza vaccination in elderly Lactobacillus plantarum CECT7315 y CECT7316 estimula la producción de inmunoglobulinas tras la vacunación contra la influenza en ancianos
Objective: The effectiveness of influenza vaccination in preventing illness is lower in the elderly; this is why the ability of Lactobacillus plantarum CECT 7315/7316 to stimulate the response to influenza vaccination in elderly was evaluated. Research methods and procedures: A randomized, double-blind, placebo-controlled human trial including 60 institutionalized volunteers aged 65-85 years was performed. All the volunteers were vaccinated with a trivalent influenza vaccine (A/Wisconsin/67/2005 NYMC X-161B (H3N2), A/Solomon Islands/3/2006 (H1N1) and B/Malaysia/2506/2004) for the Spanish vaccine campaign 2006/2007. The consumption of the probiotic began between three and four months after the vaccination. Volunteers were randomly assigned to one of three following groups: group A (receiving 5*10(9) cfu/day of L. plantarum CECT 7315/7316 in 20 g powdered skim milk), group B (receiving 5*10(8) cfu/day of L. plantarum CECT 7315/7316 in 20 g powdered skim milk) and group C or placebo (20 g powered skim milk). The participants consumed the probiotic during 3 months. Results: The consumption of L. plantarum CECT 7315/7316 during 3 months after influenza vaccination increased the levels of influenza-specific IgA and IgG antibodies. Moreover, a trend towards an increase in influenza-specific IgM antibodies was also observed. Conclusion: L. plantarum CECT7315/7316 has an immunostimulating effect and could be used to improve the response to influenza vaccination in elderly.Introducción y objetivos: La efectividad de la vacunación contra la influenza es menor en ancianos por lo que en este trabajo se evalúa la habilidad de las cepas de Lactobacillus plantarum CECT 7315/7316 para estimular la respuesta a la vacuna contra la influenza en ancianos. Métodos: 60 ancianos institucionalizados (65-85 años) participaron en un diseño aleatorizado, doble ciego controlado por placebo. Los voluntarios fueron vacunados con una vacuna trivalente contra influenza (A/Wisconsin/67/2005 NYMC X-161B (H3N2), A/Solomon Islands/3/2006 (H1N1) and B/Malaysia/2506/2004) durante la campaña española de vacunación 2006/2007. El consumo del probiótico empezó entre tres y cuatro meses después de la vacunación. Los voluntarios fueron distribuidos aleatoriamente en tres grupos: grupo A (recibieron 5*10(9) ufc/día de L. plantarum CECT 7315/7316 en 20 g de leche desnatada en polvo), grupo B (recibieron 5*10(8) ufc/día de L. plantarum CECT 7315/7316 en 20 g de leche desnatada en polvo) y grupo C o placebo (recibieron 20 g de leche desnatada en polvo). Los participantes consumieron el probiótico durante 3 meses. Resultados: El consumo de L. plantarum CECT 7315/7316 durante tres meses después de la vacunación contra influenza incrementó los niveles de anticuerpos IgA y IgG específicos contra la influenza. Además, se observó una tendencia hacia un incremento en los niveles de anticuerpos IgM específicos contra la influenza. Conclusiones: Las cepas de L. plantarum CECT 7315/7316 tienen un efecto inmunoestimulador y podrían utilizarse para mejorar la respuesta a la vacuna contra la influenza en ancianos
