A randomized trial to evaluate effectiveness and cost effectiveness of naturopathic cranberry products as prophylaxis against urinary tract infection in women The Canadian journal of urology. 2002 EBM Reviews - Cochrane Central Register of Controlled Trials
Cranberry prevents bacterial adhesion to the genitourinary system and acidify the bowel ecosystem which promotes probiotics growth
What dose the literature say about probiotics and its role in health?
Studies reviewed and quoted in this presentation, mostly published the year 2000 onward
Probiotics are defined as “live microorganism which, when administered in adequate amounts confer a health benefits on the host”
Probiotic e.g. Lactobacillus Bacteria Bifidobacteria spp
Prebiotics defined as “Non digestible substances that provides a beneficial physiological growth or activity of a limited number of indigenous bacteria”
Lactobacillus as a probiotic for preventing urogenital infections A. Andreu Reviews in Medical Microbiology2004
The main indications for probiotic Lactobacillus use in urogenital tract infections would include recurrent urinary tract infection in healthy pre-menopausal and post-menopausal women, post-infection prophylaxis to re-establish the vaginal flora and prevent future episodes, bacterial vaginosis and recurrent vaginal candidiasis.
Are probiotics useful in controlling gastric colonization by Helicobacter pylori? GOTTELAND Alimentary Pharmacology & Therapeutics. April 2006.
Probiotics do not eradicate H. pylori but maintain lower levels of this pathogen in the stomach; in combination with antibiotics, probiotics may increase eradication rate and/or decrease adverse effects.
Colonic Ecosystem In the Newborn Baby?
Colonic Ecosystem The colon of the fetus is sterile
Colonic Ecosystem • Maternal Vaginal flora • Personnel present at birth • Mothers breast milk, etc. • In 2 days colonic flora up to 10 to power 8 per gram stool
Colonic Ecosystem In the following days selection among the colonic bacteria occurs
Colonic Ecosystem In exclusively breast fed baby 90 – 95% of the colonic bacteria will be Bifidobacteria
Bifidogenic Ingredients • Low protein • High whey protein • Low phosphorus content • Acidic intestinal environment • Growth of acid- tolerant Bifidobacteria
Intestinal flora of breastfed and formula-fed infants Harmsen HJM et al. JPGN 2000
Bifidobacteria counts in intestinal flora (Fish method) Palermo study 2002
Bacteria-Epithelial Cross-Talk Refers to the communication or interaction process between bacteria and the epithelial cells Through this, bacteria can colonize the gut, maintain health or cause disease Possibly due to certain glycoconjugate receptors on the cells Walker WA, 2000
Porbiotic Recent current research and publications are more pro probiotic
A study of oral Bifidobacteria supplement to preterm and newborn babies showed a correlation between lacking Bifidobacteria predominance and sepsis. Z. Geburtsh Neonatology 1999
Administration of Lactobacillus rhamnosus GG to preterm babies for 7 days can influence the incidence of NEC, sepsis and UTI Dani C, et al Biol Neonate 2002
Regular intake of Lactobacillus rhamnosus GG significantly reduced the risk of nosocomial diarrhea among hospitalized infants and toddlers Szajewska H, et al J Pediatr 2001
A placebo- controlled trial of Lactobacillus rhamnosus GG prevents diarrhea in undernourished children in underdeveloped countries Oberhelman RA J Pediatr 1999
ORS enriched with Lactobacillus rhamnosus GG reduces the duration of diarrhea ameliorate the course and help early discharge from hospital Multicenter European Trial J Gastroenterol Nutr. 2000

Early predictors of asthma Jennifer K. et al Allergy and Clinical Immunology 2002
Early development of atopy is a strong predictor of later asthma Jennifer K. Allergy and Clinical Immunology 2002,
Prenatal factors predicting asthma • Parental atopy and asthma • Early or threatened labour, • Restricted growth and • Malposition of the foetus
Prenatal factors predicting asthma Cont. • Gestational age greater than 40 weeks • low levels of IgE at birth • greater than 40 weeks • Malaria parasites in cord blood were strong risk factors for later asthma ??
