Clinical relevance of endoscopic assessment of inflammation in ulcerative colitis: Can endoscopic evaluation predict outcomes?

Table 3 Correlation of endoscopic activity with clinical symptoms

Ref.	Study characteristics	Results
Karoui et al[35]	Prospective observational study.	CRP correlated well with DAI and Rachmilewitz score
2011	101 patients with UC in remission.	Correlation between DAI and Rachmilewitz was not statistically significant
Tunisia	CRP, Disease activity index and Rachmilewitz scores used
Osada et al[36]	Prospective observational study.	Clinical symptoms correlated with left sided disease activity.
2008	54 patients with UC.	CRP and ESR correlated well with right sided inflammation.
Japan	CRP, ESR, Mayo endoscopic subscore, Lichtiger’s clinical activity scores used.
Turner et al[37]	Prospective observational study.	Disease activity was best assessed by Walmsley and PUCAI followed by Partial Mayo score and Rachmilewitz
2009	86 patients with UC. Disease activity was measured using 9 different activity indices
Canada

CRP: C-reactive protein; DAI: Disease activity index; ESR: Erythrocyte sedimentation rate; PUCAI: Paediatric ulcerative colitis activity index; UC: Ulcerative colitis.
