Curcumin in Combination With Mesalamine Induces Remission in Patients With Mild-to-Moderate Ulcerative Colitis in a Randomized Controlled Trial

A systematic prospective comparison of noninvasive disease activity indices in ulcerative colitis.

First multicenter study of modified release phosphatidylcholine "LT-02" in ulcerative colitis: a randomized, placebo-controlled trial in mesalazine-refractory courses.

Background Chronic pain (CP) is a common symptom in patients with inflammatory bowel disease. This study aimed to examine its prevalence, severity, clinical associations, and impact on psychological well-being and to identify patient factors that independently predict the presence of severe/disabling pain. Methods One hundred and twenty consecutive patients with inflammatory bowel disease attending a hospital-based clinic provided information through questionnaires on quality of life, mood disturbance, and functional gut symptoms. Those who had CP (pain occurring every day for 3 months within the past 6 months) provided additional information on the pain's intensity and associated disability and management and coping strategies. Results Forty-six patients (38%) had CP, most commonly in the abdomen (91%), and they had higher disease activity, reduced quality of life, and more depression and anxiety and took more paracetamol and opiates than those without. These indices were worse in the subgroup of 23 with moderate-severe pain/disability. Criteria for irritable bowel syndrome were met in 70% of those with pain irrespective of its severity. Multivariate analysis identified 4 independent associations with moderate-severe pain/disability: active disease (odds ratio, 49 [95% confidence intervals, 1.6-1455]), catastrophizing tendency (35 [3-228]), medication belief score (0.05 [0.005-0.55], and depression score (1.80 [1.02-3.17]). Conclusions CP has major effects on quality of life and functional and social outcomes. Active disease and maladaptive coping strategies and negative attitudes and beliefs toward symptoms are independently associated with more severe pain. Management strategies should move the focus away from analgesic dependence toward psychosocial intervention and nonpharmacologic therapy.

Chronic pain in inflammatory bowel disease: characteristics and associations of a hospital-based cohort.

Background:

Subjective physician assessment is the cornerstone of routine ulcerative colitis (UC) management. Endoscopic and histologic assessment of UC provides objective measures of inflammatory disease activity. The level of agreement between physician impression of UC activity and endoscopic disease activity has not been evaluated. The aim was to assess the level of agreement between physician's clinical impression of UC disease activity and endoscopic and histologic findings of inflammation.



Methods:

Using the Medical Archival Retrieval System at the University of Pittsburgh Medical Center, we reviewed clinical information on all UC patients between 1995 and 2008 who had clinic visits recorded prior to colonoscopy. Clinical UC disease activity was defined by the physician's clinical impression and the endoscopic and histologic activity by colonoscopy with biopsy. The level of agreement between colonoscopy assessment of UC with histologic and clinical assessment was determined by sensitivity, specificity, positive and negative predictive values, and the kappa coefficient.



Results:

There were 369 UC patients who had a clinic visit proximate to a colonoscopy. The mean age of patients was 46 ± 16 years (50% female). The performance of clinical impression in recognizing disease activity, as determined by endoscopy, was relatively poor: sensitivity = 56.0%, predictive value negative = 56.8%, kappa coefficient = 0.35. In contrast, the performance of histological evaluation in recognizing disease activity was markedly better: sensitivity = 93.5%, predictive value negative = 89.1%, kappa coefficient = 0.70.



Conclusions:

The physician's clinical impression of UC activity shows poor agreement with endoscopy and histology, with over one-third of patients with chronic inflammation underrecognized by clinical impression. The consequences of underestimated UC activity by clinical assessment may include undertreatment of active disease and uncontrolled chronic inflammation. (Inflamm Bowel Dis 2011;)

Physician assessment of ulcerative colitis activity correlates poorly with endoscopic disease activity.

Summary

Background

Ulcerative colitis disease activity indices have not been formally validated.



Aim

To analise quantitatively the psychometric and performance validity of two non-endoscopic indices for ulcerative colitis, the Simple Clinical Colitis Activity Index and the Seo Index.



Methods

In 66 patients with ulcerative colitis, the measurement of disease activity was repeated with the two non-endoscopic indices, St Mark's Index, and the Inflammatory Bowel Disease Questionnaire. Psychometric validity was evaluated by measuring the content, construct, criterion-convergent and criterion-predictive validity on a 0–1 scale. Performance validity was evaluated by measuring the reproducibility and responsiveness on a 0–1 scale.



Results

The Simple Clinical Colitis Activity Index had good to excellent psychometric and performance validity, while the Seo Index had moderate to excellent psychometric validity and moderate to good performance validity. The Simple Clinical Colitis Activity Index had weaknesses in content validity and in responsiveness. The Seo Index had weaknesses in content validity, construct validity and responsiveness.



Conclusions

These two non-endoscopic indices for ulcerative colitis have good psychometric and performance validity, and are now the most rigorously validated disease activity indices for ulcerative colitis. The Simple Clinical Colitis Activity Index appears to have better overall validity. Quantitative evaluation identifies weaknesses in disease activity indices, and can lead to better disease activity indices for ulcerative colitis.
