The course of inflammatory bowel disease during pregnancy and postpartum: a prospective European ECCO-EpiCom Study of 209 pregnant women.

BACKGROUND: The impact of pregnancy on the course of IBD is still controversial. AIM: To investigate the impact of pregnancy on IBD and to search for factors with potential impact on remission. METHODS: Pregnant IBD women from 12 European countries were enrolled between January 2003 and December 2006 and compared at conception (1:1) with nonpregnant IBD women. Data on disease course were prospectively collected at each trimester during pregnancy and in the postpartum (6 months) using a standardised questionnaire. RESULTS: A total of 209 pregnant IBD women were included: 92 with Crohn's disease (CD; median age 31 years, range 17-40) and 117 with ulcerative colitis (UC; median age 32 years, range 19-42). No statistically significant difference in disease course during pregnancy and postpartum was observed between pregnant and nonpregnant CD women. Longer disease duration in CD and immunosuppressive therapy were found to be risk factors for activity during pregnancy. Pregnant UC women were more likely than nonpregnant UC women to relapse both during pregnancy (RR 2.19; 95% CI: 1.25-3.97, 0.004) and postpartum (RR 6.22; 95% CI: 2.05-79.3, P = 0.0004). During pregnancy, relapse was mainly observed in the first (RR 8.80; 95% CI 2.05-79.3, P < 0.0004) and the second trimester (RR 2.84, 95% CI 1.2-7.45, P = 0.0098). CONCLUSIONS: Pregnant women with Crohn's disease had a similar disease course both during pregnancy and after delivery as the nonpregnant women. In contrast, pregnant women with ulcerative colitis were at higher risk of relapse during pregnancy and in the postpartum than nonpregnant ulcerative colitis women.

A comparative study of faecal occult blood kits in a colorectal cancer screening program in a cohort of healthy construction workers.

BACKGROUND: The incidence of colorectal cancer (CRC) has been increasing. We evaluated uptake rates and outcomes of faecal immunochemical test (FIT) and Guaiac test (gFOBT) kits as part of a two-step CRC screening. METHODS: A 3-year CRC screening program for a defined population of construction workers was conducted. Those satisfying the inclusion criteria were provided with gFOBT or FIT kits. Individuals testing positive were invited for a colonoscopy. RESULTS: A total of 909 faecal testing kits were distributed. Age range was 53-60 years. Compliance rate was higher for FIT (58.3%) as compared to gFOBT (46.7%) (p = 0.0006). FIT detected adenomatous polyps and CRC in 37.5 and 25%, respectively, whereas; gFOBT detected 23.5 and 18%. Colonoscopies were normal in 53 and 25% tested positive by gFOBT and FIT, respectively (p = 0.016). CONCLUSION: The FIT was more cost-effective when compared with gFOBT with higher return rate, sensitivity and specificity.

Favorable effect of immunomodulator therapy on bone mineral density in multiple sclerosis.

BACKGROUND: Osteoporosis is a complication of multiple sclerosis (MS), especially if corticosteroid therapy is given. Little is known about the effect on bone of immunomodulatory therapy (IMT) for MS. AIM: We sought to evaluate bone mass in patients with MS on IMT. METHODS: We measured bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA) in 37 patients with MS who received IMT. Different IMTs were administered: interferon beta-1a in 70%, interferon beta-1b in 27% and Glatiramer in 3%. High-dose pulse corticosteroid therapy (intravenous methylprednisolone 500 mg) was given to 81% ranging from 1 to 17 courses. RESULTS: Both mean BMD Z-score at spine of 0.53 (CI, 0.15-0.92; P = 0.0084) and mean BMD Z-score at femur of 0.72 (CI, 0.42-1.01; P < 0.0001) were significantly greater than zero. CONCLUSIONS: IMT may have a favorable effect on bone in patients with MS even in the presence of pulse steroid therapy.

How much heparin do we really need to go on pump? A rethink of current practices.

OBJECTIVES: Patients undergoing myocardial revascularisation using extracorporeal circulation require heparin anticoagulation. We aimed to evaluate the effect of reducing heparin dosage on target activated clotting time (ACT) and postoperative blood loss. METHODS: In a prospective randomised trial, 195 patients undergoing isolated primary CABG were randomised into four groups A, B, C, and D receiving an initial heparin dosage of 100, 200, 250 and 300 iu/kg, respectively. Extra incremental heparin (50 iu/kg) was added if required to achieve a target ACT of 480 s before initiating cardiopulmonary bypass. Postoperative blood loss was measured from the time of heparin reversal to drain removal 24h later. RESULTS: Target ACT was achieved in 0, 63, 68.3 and 82.4% of patients in groups A, B, C and D, respectively, after the initial dose of heparin. In group B, of those not achieving target act a single increment of heparin was sufficient to achieve target ACT in further 18.6%. The mean ACT after the initial dose in groups B, C and D was 482.9, 519 and 588 s, respectively (P<0.05). Postoperative blood loss in millilitre per kilogram was directly proportional to preoperative heparin dose. CONCLUSIONS: Patients receiving lower dose of heparin has lower postoperative blood loss. Of those achieving the target ACT, group B was significantly the closest to the target ACT. A starting dose of 200 iu/kg of heparin and if necessary one 50 iu/kg increment achieved target ACT in 81.5% of patients. The added benefit of significant drop in postoperative blood loss is evident.
