Effects of HIV, antiretroviral therapy and prebiotics on the active fraction of the gut microbiota

2018

In a recent blinded randomized study, we found that in HIV-infected individuals a short supplementation with prebiotics (scGOS/lcFOS/glutamine) ameliorates dysbiosis of total gut bacteria, particularly among viremic untreated patients. Our study goal was to determine the fraction of the microbiota that becomes active during the intervention and that could provide additional functional information.A total of six healthy individuals, and 16 HIV-infected patients comprising viremic untreated patients (n = 5) and antiretroviral therapy-treated patients that are further divided into immunological responders (n = 7) and immunological nonresponders (n = 4) completed the 6-week course of prebiotic …

Paediatric research in Spain: Challenges and priorities. INVEST-AEP Platform

2018

Research is the cornerstone of medical progress. Paediatric research has its own nuances and represents an additional challenge due to the intrinsic characteristics of the paediatric population compared with adults. Despite the tremendous importance of childhood health and its impact during adulthood, society is still not convinced about the importance of conducting research in paediatrics. This also applies to paediatricians themselves, who think about research as a discipline that does not directly involve them.The Spanish Academy of Paediatrics has developed a specific research platform- INVEST-AEP- to try to help and answer the challenges associated with paediatric research in the socie…

Paediatric research in Spain: Challenges and priorities. INVEST-AEP Platform

2018

La investigación clínica es la piedra angular para el desarrollo de la Medicina, y, en el ámbito de la Pediatría, supone un reto adicional debido a las peculiaridades que diferencian a los niños de los adultos. A pesar del enorme impacto de la salud infantil en el resto de la vida, nuestra sociedad aún no está suficientemente concienciada sobre la importancia de la investigación pediátrica, que, en general, se encuentra también muy alejada del día a día de quienes nos dedicamos a esta profesión. Desde la Asociación Española de Pediatría (AEP) se ha creado una plataforma específica de investigación —INVEST-AEP— para dar respuesta específica a los retos de la investigación en el seno de nuest…

Effects of Immunonutrition in Advanced Human Immunodeficiency Virus Disease: A Randomized Placebo-controlled Clinical Trial (Promaltia Study)

2018

[Background]: While nutritional interventions with prebiotics and probiotics seem to exert immunological effects, their clinical implications in human immunodeficiency virus (HIV)–infected subjects initiating antiretroviral therapy (ART) at advanced HIV disease remain unclear.

Gut Bacteria Metabolism Impacts Immune Recovery in HIV-infected Individuals.

2016

While changes in gut microbial populations have been described in human immuno-deficiency virus (HIV)-infected patients undergoing antiretroviral therapy (ART), the mechanisms underlying the contributions of gut bacteria and their molecular agents (metabolites and proteins) to immune recovery remain unexplored. To study this, we examined the active fraction of the gut microbiome, through examining protein synthesis and accumulation of metabolites inside gut bacteria and in the bloodstream, in 8 healthy controls and 29 HIV-infected individuals (6 being longitudinally studied). We found that HIV infection is associated to dramatic changes in the active set of gut bacteria simultaneously alter…

HIV infection results in metabolic alterations in the gut microbiota different from those induced by other diseases.

2016

Imbalances in gut bacteria have been associated with multiple diseases. However, whether there are disease-specific changes in gut microbial metabolism remains unknown. Here, we demonstrate that human immunodeficiency virus (HIV) infection (n=33) changes, at quantifiable levels, the metabolism of gut bacteria. These changes are different than those observed in patients with the auto-immune disease systemic lupus erythaematosus (n=18), and Clostridium difficile-associated diarrhoea (n=6). Using healthy controls as a baseline (n=16), we demonstrate that a trend in the nature and directionality of the metabolic changes exists according to the type of the disease. The impact on the gut microbia…
