Pregnancy and breastfeeding in inflammatory bowel disease

Inflammatory bowel disease (IBD) is frequent in women during their peak reproductive years. Accordingly, a significant number of questions and uncertainties arise from this population regarding the risk of transmission of IBD to the offspring, the impact of the disease and therapies on the fertility, the role of the disease on the course of the pregnancy and the mode of delivery, the impact of the therapy on the pregnancy and fetal development as well as breastfeeding. The safety of medical therapy during pregnancy and lactation is a major concern for both pregnant women and their partners as well as for physicians. As a general rule, it can be stated that the benefit of continuing medical therapy in IBD during pregnancy outweighs the potential risks in the vast majority of instances. This article will review recent developments on this topic consistent with the European Crohn's and Colitis Organization guidelines.

Retrospective comparison of maternal vs. HPA-matched donor platelets for treatment of fetal alloimmune thrombocytopenia

In fetal alloimmune thrombocytopenia (FAIT), transplacental maternal antibodies cause destruction of fetal platelets. FAIT is similar to fetal Rhesus haemolytic disease, but half of the affected fetuses are born to primiparous women. In 10-20% of cases, prenatal and perinatal intracranial haemorrhages are reported. Different therapeutic approaches have been described, including maternally administered high-dose intravenous immunoglobulin (high dose IVIG) without or with steroids or intrauterine transfusion (IUT) of compatible platelets. For the latter, the use of plasma-free maternal and donor platelets has been described, but a comparison of these two sources of platelets has not been reported.

Reduced muscle mass and bone size in pediatric patients with inflammatory bowel disease

BACKGROUND: Decreased bone mineral density has been reported in children with inflammatory bowel disease (IBD). We used peripheral quantitative computed tomography (pQCT) to assess bone mineralization, geometry, and muscle cross-sectional area (CSA) in pediatric IBD. METHODS: In a cross-sectional study, pQCT of the forearm was applied in 143 IBD patients (mean age 13.9 +/- 3.5 years); 29% were newly diagnosed, 98 had Crohn's disease, and 45 had ulcerative colitis. Auxological data, cumulative glucocorticoid dose, disease activity indices, laboratory markers for inflammation, and bone metabolism were related to the results of pQCT. RESULTS: Patients were compromised in height (-0.82 +/- 1.1 SD), weight (-0.77 +/- 1.0 SD), muscle mass (-1.12 +/- 1.0 SD), and total bone cross-sectional area (-0.79 +/- 1.0 SD) compared to age- and sex-matched healthy controls (z-scores). In newly diagnosed patients, the ratio of bone mineral mass per muscle CSA was higher than in those with longer disease duration (1.00 versus 0.30, P = 0.007). Serum albumin level and disease activity correlated with muscle mass, accounting for 41.0% of variability in muscle mass (P < 0.01). The trabecular bone mineral density z-score was on average at the lower normal level (-0.40 +/- 1.3 SD, P < 0.05). CONCLUSIONS: Reduced bone geometry was explained only in part by reduced height. Bone disease in children with IBD seems to be secondary to muscle wasting, which is already present at diagnosis. With longer disease duration, bone adapts to the lower muscle CSA. Serum albumin concentration is a good marker for muscle wasting and abnormal bone development.

Mechanical bowel preparation and antimicrobial prophylaxis in elective colorectal surgery in Switzerland--a survey

The aim of this study was to assess the use of mechanical bowel preparation (MBP) and antimicrobial prophylaxis in elective colorectal surgery in Switzerland.

Avoidance and inhibition do not predict nonrespondent bias among patients with inflammatory bowel disease

It has been suggested that participant withdrawal from studies can bias estimates. However, this is only possible when withdrawers and nonwithdrawers differ in an important way. We tested the hypothesis that withdrawers are more likely than nonwithdrawers to be avoidant and negatively affected.

[The effect of stress-relieving interventions on inflammatory bowel disease: quality assessment of 10 therapeutic studies]

Patient comments and empirical studies suggest an influence of stress on inflammatory bowel diseases (IBD). We performed a quality assessment of previous studies on the effect of stress reduction on IBD in order to formulate recommendations for future studies and to evaluate their potential for improvement.

Appropriateness of therapy for fistulizing Crohn's disease: findings from a national inflammatory bowel disease cohort

About 30-50% of patients with Crohn's disease (CD) develop fistulae, implying significant disease burden and complicated clinical management.

Feasibility of small bowel flow rate measurement with MRI

To evaluate whether it is feasible to measure the segmental flux of small bowel content using MR phase-contrast (PC) pulse sequences.
