Round 1

Reviewer 1 Report

This review provides a comprehensive overview about the different options of prevention and treatment of bacterial translocation in leaky-gut syndrome (LGS).

Minor comments:

  • a lot of typos/spelling errors (e.g. "is showed"....) are in text, please correct by native speaker
  • give full meaning of all abbreviations when first mentioned
  • provide a complete list of abbreviations
  • explain throughout the manuscript and abstract: "outside the gastrointestinal tract", "outside GI", and "bacterial translocation", i.e. you also mean that bacteria and other pathogens transfer "into the body/into the system"
  • state which time period is spanned by your literature search 
  • line 56: "preventing BT ...therapeutic opportunity" = paradox
  • Figure 1: describe in figure legend what is drawn, and label arrows and molecules in the picture; present in clear colours or grey scale (e.g. commensals and pathogens should be better distinguished)
  • line 79: give short results sentence: how many papers were found, how many included, how long was search time frame
  • line 113. "mucin-degrading species" - is this a positive or negative effect?
  • line 115: IPEC-J2 cells: define/describe
  • line 126: discuss whether BT-association with different diseases like CD, UC.....is the reason or the result; so is BT the reason for the diseases, or is the disease first and BT thereafter (might be different for CD vs. abdominal surgery)
  • lines 151-155: role of microbiota/bacteria unclear, just IL-10-deficiency discussed
  • line 193: define resistin-like
  • line 233: what are the control groups in this paper?
  • figure 2: label arrows, describe drawing in figure legend; typo: pentoxifyllin
  • Table 1: give English names for plant sources in addition to botanical names
  • line 570: describe the mode of action of pentoxifyllin
  • Table 2: sort clearly / provide lines between paragraphs / percentages
  • Tabel 2: describe "child-pugh"
  • line 696: should be PPI
  • line 707: rephrase to "...translocation of bacteria or endotoxin in LGS is associated with GI diseases."
  • line 729: what is meant by increased zonulin? increased plasma levels of zonulin and endotoxin?
  • please give a short summary sentence below all your individual paragraphs (i.e. after diet, probiotics, supplements...) which conclusions can be drawn or what research is missing
  • line 739: summing up all evidence, can we really conclude on treatment of LGS, or is it rather prevention?

Reviewer 2 Report

The review article “Preventing bacterial translocation in patients with leaky gut syndrome: nutrition and pharmacological treatment options” is interesting and written well. The manuscript covers a different aspect of dietary intake on gastrointestinal bacterial translocation. The manuscript looks sound and broadly discussed.
