An open-label randomized controlled trial was performed to examine the efficacy of exclusive enteral nutrition as adjunctive treatment to intravenous corticosteroids in individuals with acute severe ulcerative colitis.
In patients suffering from acute
severe ulcerative colitis, the exclusive enteral nutrition for seven days may
augment corticosteroid responsiveness.
An
open-label randomized controlled trial was performed to examine the efficacy of
exclusive enteral nutrition as
adjunctive treatment to intravenous corticosteroids in individuals with acute
severe ulcerative colitis.
In
total, 62 participants (mean age 35.3 ± 12.1 years) were randomized either to
an exclusive enteral nutrition group (subjects received a semi-elemental
formula for seven days along with the standard of care, n=32) or standard of
care group (n=30). Corticosteroid failure, defined by the requirement for
salvage medical treatment or colectomy was the major endpoint. Utilizing 16s
ribosomal RNA sequencing, the fecal microbial analysis was carried out on day 1
and day 7 in some individuals.
In comparison with the standard of care group, the corticosteroid failure was found to be reduced in the exclusive enteral nutrition group, without any vital difference in colectomy rate. Subjects treated with exclusive enteral nutrition were found to have a shorter hospital stay, elevated albumin level at 7th day, a greater decline in serum C-reactive protein and fecal calprotectin levels, and a decreased composite outcome of colectomy/hospitalization at six months in comparison with the standard of care group, as shown below:
In comparison with the standard of
care group, the individuals receiving exclusive enteral nutrition displayed an
elevated abundance of Erysipelotrichaceae on the 7th day, with decreased
Bifidobacterium and Veillonellaceae.
The exclusive enteral nutrition for
seven days may augment corticosteroid responsiveness and is therefore advantageous
to manage acute severe ulcerative colitis patients.
