Cure of H. pylori infection is associated with reversal of iron dependence and recovery from iron deficiency anemia.

Short-term stress does not trigger exacerbation in ulcerative colitis, but long-term perceived stress increases the risk of exacerbation over a period of months to years.

SUMMARY Background: Some evidence indicates that short‐chain fatty acid (SCFA) enemas are effective in the treatment of distal ulcerative colitis. Methods: In a randomized, double‐blind, placebo‐controlled study, we tested the efficacy of a 6‐week course of topical SCFA (100 mL, twice daily enemas of sodium acetate 80 mmol/L, sodium propionate 30 mmol/L and sodium butyrate 40 mmol/L) in 40 patients with mild to moderate distal colitis. Clinical, endoscopic and histological data were collected at the beginning and end of the study. Results: Fourteen patients on SCFA improved (overall score 11.3 ± 2.0 vs. 7.4 ± 3.5) as compared to five in the placebo group (overall score 10.0 ± 1.9 vs. 8.9 ± 2.5). In the SCFA‐treated group all parameters significantly improved except the number of bowel motions, whereas no significant changes were recorded in the control group. A statistically significant difference between the two treatment regimens, however, was observed only for intestinal bleeding (P < 0.05), urgency (P < 0.02) and the patient self‐evaluation score (P < 0.05). This was probably due to the random inclusion of more patients with moderate disease into the SCFA‐treated group, thus causing pre‐trial differences between the two groups. Conclusion: the present study confirms that irrigation with SCFA enemas is effective in distal colitis, and may represent an alternative therapeutic tool in the treatment of the disease.

SICUS is an accurate method for the detection of small intestinal complications in CD. Noninvasive SICUS is valuable as a primary investigative method for evaluating and planning proper treatment in patients with severe CD of the small bowel.

A screening for celiac disease should be carried out in adult patients with iron deficiency anemia. Recovery from anemia occurs between 6 and 12 months on a gluten-free diet alone as a consequence of normalization of histological alterations of the intestinal mucosa.
