TL;DR: It is concluded that oral 5-ASA administered in a dosage of 4.8 g per day is effective therapy, at least in the short term, for mildly to moderately active ulcerative colitis.
Abstract: We assessed oral 5-aminosalicylic acid (5-ASA) prepared with a pH-sensitive polymer coating in 87 patients with mildly to moderately active ulcerative colitis in a double-blind, placebo-controlled trial. Patients were randomly assigned to receive 5-ASA at a dosage of either 4.8 or 1.6 g per day or placebo for six weeks. The outcome was monitored by flexible proctosigmoidoscopic examinations and physicians' assessments at three-week intervals and by patients' recordings of daily symptoms. Results showed 24 percent complete and 50 percent partial responses in those receiving 4.8 g of 5-ASA per day as compared with 5 percent complete and 13 percent partial responses in those receiving placebo (P less than 0.0001, rank-sum test). At a dosage of 1.6 g per day, the response was twice as good as with placebo, but the difference did not reach statistical significance (P = 0.51). Age, sex, duration of disease, duration of active symptoms, or extent of disease did not affect the clinical outcome. We conclude that oral 5-ASA administered in a dosage of 4.8 g per day is effective therapy, at least in the short term, for mildly to moderately active ulcerative colitis.

TL;DR: Variability in collagen thickness may be related to disease phase and increases the need to obtain multiple biopsy specimens from the sigmoid colon and rectum and the optimal treatment for collagenous colitis is difficult to determine.
Abstract: Collagenous colitis is an unusual cause of chronic, watery diarrhea. To characterize this disease, we reviewed biopsy specimens and the clinical records of 17 patients (9 women and 8 men) with this diagnosis. Intermittent diarrhea with symptom-free intervals lasting years was found in 7 of the 17 patients. Two patients had incapacitating arthralgias, and nine had a mild weight loss. Collagen deposition beneath the surface epithelium formed a continuous layer in 11 but was discontinuous in 5 of the 16 patients who had undergone rectal or colonic biopsies at our institution. The thickness of the collagen band was variable (maximum, 93 μm). The symptoms of the patients did not correlate with the thickness of the collagen layer. Variability in collagen thickness may be related to disease phase and increases the need to obtain multiple biopsy specimens from the sigmoid colon and rectum. The optimal treatment for collagenous colitis is difficult to determine because three of six patients treated only symptomatically in our study had resolution of their diarrhea.
