MICROBIOTA UMANO : LA COMPOSIZIONE DELLA FLORA BATTERICA
DETERMINA LA NOSTRA SALUTE .HUMAN MICROBIOTA : GUT MICROBIOTA COMPOSITION
CORRELATES WITH DIET AND HEALTH IN THE ELDERLY
The human
body is colonized by a vast number of microbes, collectively referred to as the
human microbiota.
Il microbiota umano è l'insieme di microorganismi
simbiontici che si trovano nel tubo digerente dell'uomo.
Definito un “super-organismo”, il microbiota è composto da
un numero di batteri pari a 6 volte il totale delle cellule che compongono
l’intero corpo umano e da almeno quattro milioni di tipi di batteri diversi.
I principali batteri che popolano l’apparato sono i
Bifidobatteri, i Lattobacilli e gli Eubacterium, ma ve ne sono di numerose
altre specie e svolgono funzioni essenziali.
• Favoriscono la biodisponibilità di alcuni nutrienti, e la
metabolizzazione delle calorie;
• sintetizzano diverse vitamine;
• regolano l’espressione del sistema immunitario nella
mucosa intestinale;
• sostengono la peristalsi intestinale
• proteggono la mucosa intestinale – e dunque l’intero
organismo – dalle aggressioni di microrganismi patogeni, prevenendo così la
comparsa di molte infezioni.
In particolare, la soluzione consigliata dalla Nutraceutica
Fisiologica di Regolazione, vanto della più avanzata ricerca scientifica
italiana sui protocolli di origine biologica, si basa sui principi
sintetizzabili nella formula cosiddetta delle “3 Erre”:
1. Ripulire,
2. Riparare
3. Ripopolare.
All’Università Cattolica – Policlinico A. Gemelli di Roma
sono attive sperimentazioni cliniche su alcuni pazienti con diabete
insulino-resistente in fase precoce e con colite ulcerosa ai quali è stata
sostituita la flora batterica intestinale (microbiota).
Il trapianto di microbiota è stato dimostrato essere sicuro
ed efficace per i pazienti con infezioni ricorrenti da Clostridium difficile.
Il Policlinico Gemelli è attualmente l’unico centro in Italia ed uno dei pochi
centri al mondo a praticare di routine questa terapia “La flora batterica
interagisce con le cellule immunitarie che popolano il nostro intestino –
spiega il professor Antonio Gasbarrini, Direttore dell’Unità Operativa
Complessa di Medicina Interna e Gastroenterologia preso il Policlinico A.
Gemelli e presidente del congresso EAGEN – modulando l’attività di geni chiave
per il corretto funzionamento del sistema immunitario”. Non si esclude che, con
il trapianto di microbiota, si possa porre rimedio anche a malattie gravi e
complesse come la sclerosi multipla, misteriose come l’autismo che non a caso
risulta spessissimo associato a numerosi problemi gastrointestinali.

Gut
microbiota composition correlates with diet and health in the elderly
Alterations
in intestinal microbiota composition are associated with several chronic
conditions, including obesity and inflammatory diseases. The microbiota of
older people displays greater inter-individual variation than that of younger
adults. Here we show that the faecal microbiota composition from 178 elderly
subjects formed groups, correlating with residence location in the community,
day-hospital, rehabilitation or in long-term residential care. However,
clustering of subjects by diet separated them by the same residence location
and microbiota groupings. The separation of microbiota composition significantly
correlated with measures of frailty, co-morbidity, nutritional status, markers
of inflammation and with metabolites in faecal water. The individual microbiota
of people in long-stay care was significantly less diverse than that of
community dwellers. Loss of community-associated microbiota correlated with
increased frailty. Collectively, the data support a relationship between diet,
microbiota and health status, and indicate a role for diet-driven microbiota
alterations in varying rates of health decline upon ageing. Marcus J. Claesson

In
particular, the solution recommended by Nutraceutical Physiological Regulating,
boast of the most advanced scientific research Italian protocols of biological
origin, is based on the principles summarized in the formula of the so-called
"3 R":
1 Clean Up,
(ripulisci)
2. Repair
(ripara)
3. Peopling
(ripopola)
Catholic
University - Policlinico A. Gemelli in Rome are active clinical trials on
patients with insulin-resistant diabetes at an early stage and with ulcerative
colitis who have been replaced with the intestinal flora (microbiota).
The
microbiota transplantation has been shown to be safe and effective for patients
with recurrent infections from Clostridium difficile.
The
Policlinico Gemelli is currently the only center in Italy and one of the few
centers in the world to practice this routine therapy
"The bacterial
flora interacts with immune cells that populate our gut - says Professor
Antonio Gasbarrini, Complex Director of the Unit of Internal Medicine and
Gastroenterology at the Policlinico A. Gemelli and Congress president Eagen -
modulating the activity of key genes for the proper functioning of the immune
system. "
It is
possible that, with the microbiota transplantation, can be remedied even in
serious and complex diseases such as multiple sclerosis, mysterious as autism
which not coincidentally is often associated with several gastrointestinal
problems.
