Evaluation and Discussion

Transplant Evaluation : None in particular.
Pre- and post-transplant flora balance test changes :
A larger percentage cannot be classified as Other, and the diversity of intestinal flora is low.
The ideal ratio of C-cluster IX to C-cluster XIVab is 1:4 from a mental point of view, but the ratio of XIVab is higher at 1:9.
The detection of Equol-producing bacteria (tissue regeneration), C cluster 11, and XV (inflammatory response) suggests acute inflammation, and the percentage of C cluster XIVab may be high to maintain that immune tolerance state.
Also, I understand that you have had appendicitis.
The appendix is the organ responsible for intestinal immunity (IgA) and affects the bacterial flora balance. Damage to the appendix may result in an inadequate intestinal barrier and cause the preceding inflammation.
Hence, intestinal damage may cause inadequate immune tolerance, which may be the cause of uncontrolled allergic reactions.
Blood test changes : under inspection
POMS2 SCORE CHANGE : under inspection

Transplant General Comments and Discussion :
