Distal ulcerative colitis refractory to rectal mesalamine: role of transdermal nicotine versus oral mesalamine.
キーワード
概要
BACKGROUND
Distal ulcerative colitis usually responds to treatment with rectal mesalamine, but the management of refractory cases is poorly defined.
OBJECTIVE
To evaluate the possible therapeutic benefit of transdermal nicotine versus oral mesalamine.
METHODS
Thirty patients with left-sided ulcerative colitis unresponsive to treatment with a mesalamine 4 g enema at bedtime were randomly allocated to additional therapy with either transdermal nicotine 15 mg daily or oral mesalamine 800 mg tid for four weeks. Clinical remission was evaluated by Rachmilewitz's activity index and confirmed by sigmoidoscopy.
RESULTS
Remission was observed in 12 of 15 patients receiving additional treatment with nicotine and in five of 15 patients receiving additional treatment with oral mesalamine (P=0.027).
CONCLUSIONS
The addition of transdermal nicotine to treatment with mesalamine enemas is significantly superior to combined therapy with oral and rectal mesalamine in patients with distal ulcerative colitis refractory to rectal mesalamine alone.
