Preventive Effect of Probiotics on Oral Mucositis Induced by Cancer Treatment: A Systematic Review and Meta-Analysis
International journal of molecular sciences (2022) · Meta analysis · n=708
Three trials using Lactobacilli-based probiotics reported that the incidence of oral mucositis in the probiotic group was significantly low (risk ratio [RR] = 0.84, 95% confidence interval [CI] = 0.77−0.93, p = 0.0004).

Probiotics may prevent CDAD: NNTB 65 (95% CI 48 to 97)
The points come from one dose-comparison trial, BENDIP (PMID 18473286): 165 people with diabetic polyneuropathy randomised to 300 mg, 600 mg or placebo for 6 weeks, 133 in the ITT analysis. The Neuropathy Symptom Score differed between groups in the per-protocol analysis (p=0.033) but only narrowly missed significance by intention to treat (p=0.055), and the Total Symptom Score did not differ. Improvement was more pronounced at 600 mg, and both doses were well tolerated. No higher dose was compared, so no optimal dose can be given. The minimum effective dose comes from a separate 3-week trial of 400 mg a day in 40 inpatients, where the neuropathy score and pain improved against placebo (PMID 15726875). At 300 mg a day for 24 months, a trial in 67 people with type 1 diabetes found no effect on peripheral nerve function (PMID 22446172).
AI-estimated from published studies. Interpret as directional guidance.
Probiotics has a higher evidence score (9/10 vs 5.5/10) and wins in 2 of 3 categories.
For inflammation-related symptoms, Probiotics has a higher relevance score (80 vs 15).
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
