Nutritional therapy for ulcerative colitis (UC) is controversial.
Studies are usually designed to investigate total parenteral
(TPN) or total enteral nutrition (TEN), and before these can be
compared it is necessary to differentiate between the different
therapeutic aims. The aims of artificial nutritional support in
patients with UC are the readjustment of the nutritional status,
possible remission of disease activity, and decrease in the
incidence of surgical intervention or postoperative complication.
Owing to the heterogeneity of the results published so far, it is
still difficult to compare studies. Nevertheless, they indicate
that the extent and severity of the colitis and the patient
selection are of paramount importance in the implementation of
nutritional therapy. Positive effects of TPN reported from
non-controlled studies were not confirmed by controlled trials.
Moreover, TPN was no more effective than an oral diet. Regarding
remission rates or operative interventions needed, TPN had more
side effects than and no defined advantages over TEN. TEN seems
to be useful for certain patients. In some patients with UC, it
seems to be accompanied by fewer postoperative complications.
However, a definitive conclusion on the effects of TEN or TPN is
not yet possible. In this context, certain fatty acids may have
an important role in the treatment of UC. In prospective,
randomized and controlled studies omega-3 fatty acids were found
to be therapeutically useful. A reduction of the steroid doses
needed is particularly important. Another therapeutic approach in
distal UC is seen in the rectal administration of short chain
fatty acids.
