Disease Probiotic Strain Comments
Prevention of antibiotic associated diarrhea (AAD) S. boulardi [37,38] Number needed to treat (NNT) is 10.2 to prevent one case of AAD.
Lactobacillus rhamnosus GG (LGG) [39-41] Effective on adults and children in RCT’s.
Prevention of Clostridium difficile Infection (CDI) S. boulardii, LGG, or both [52] Study results are not statistically significant.
Prevention of recurrence after first CDI S. boulardii [53] Reduction of recurrence of CDI by half.
Helicobacter pylori eradication Lactobacillus rhamnosus GG (LGG), S. boulardii, L acidophilus [55] Moderate evidence for improving eradication but good evidence of reduction in side effects leading to improved compliance.
Ulcerative Colitis E coli Nissle 1917 [68] Promising role in maintenance of remission.
  VSL#3 [70] Role in induction and maintenance of remission of UC.
Crohn’s Disease Lactobacillus rhamnosus GG (LGG) [71,72], Lactobacillus johnsonii LA1[73] No role in induction or prolonging of remission of CD.
Irritable Bowel Syndrome Bifidobacterium infantis 35624 [80], VSL#3 [81] Significant improvements in IBS symptoms.
Acute Pancreatitis Lactobacillus plantarum 299 [88] But PROPATRIA trial showed an increased incidence of infection, MODS and bowel ischemia.
Necrotizing Enterocolitis (NEC) Bifidusbacterium spp and
Lactobacillus acidophilus [148]
Prophylactic probiotics reduced NEC and mortality. Increased infection is noted among VLBW (<750 g).
Multi-Organ Dysfunction Syndrome (MODS) VSL#3 [118] Increased systemic IgA and IgG concentrations are noted but MODS scores were not significantly affected by probiotic treatment.
Allergy and Immune Response Lactobacillus rhamnosus GG (LGG) [125-127] Alone when given to mothers during pregnancy did decrease the risk of atopic dermatitis but similar results were not seen when given with other probiotic strains.
Ventilator Associated Pneumonia (VAP) Lactobacillus rhamnosus GG (LGG) [142] Number needed to treat (NNT) is 5 to prevent one case of VAP.
