We have retrospectively compared the effectiveness of five different regimens for inducing and maintaining clinical remission in 206 patients with idiopathic proctitis (n = 115) and proctosigmoiditis (n = 91). The five therapeutic regimens were: corticosteroid enemas, 5-aminosalicylic acid (5-ASA) enemas, oral 5-ASA (sulfasalazine or mesalamine), corticosteroid enemas plus oral 5-ASA, or 5-ASA enemas plus oral 5-ASA. Clinical remission was achieved within 28 days of therapy in 47%, and eventually in 94% of these patients. No significant differences in efficacy were found among the five regimens. Most patients ultimately experienced a recurrence of symptoms, but the duration of remission was significantly longer with maintenance oral sulfasalazine or mesalamine (17.2 months) than with no therapy (11.8 months), P less than 0.01. We conclude that several regimens are equally effective in inducing remission of proctitis and proctosigmoiditis, although prolonged therapy may be needed to accomplish this goal. Maintenance oral 5-ASA significantly prolongs symptomatic remission in proctitis and proctosigmoiditis.
