Risk of Adverse Pregnancy Outcomes for Women with IBD in an Expert IBD Antenatal Clinic

Background: Patients with inflammatory bowel disease (IBD) are at increased risk of adverse outcomes from pregnancy. It is unclear whether IBD indications account for the higher rate of Caesarean section (CS) in IBD patients. Methods: A retrospective cohort study of 179 IBD patients cared for in a dedicated combined IBD antenatal clinic and 31,528 non-IBD patients was performed. The outcomes were method of delivery, preterm birth, birthweight, admission to neonatal intensive care unit (NICU), and stillbirth. We analysed the associations between disease activity, medication with method of delivery, and neonatal outcomes. Results: Delivery by CS was more common in IBD patients (RR 1.45, CI 1.16−1.81, p = 0.0021); emergency CS delivery was equally likely (RR 1.26, CI 0.78−2.07, p = 0.3). Forty percent of elective CS were performed for IBD indications. Stillbirth was five-fold higher in IBD patients (RR 5.14, CI 1.92−13.75, p < 0.001). Preterm delivery, low birthweight, and admission to NICU were not more common in patients with IBD, and IBD medications did not increase these risks. Active disease during pregnancy was not associated with adverse outcomes. Conclusions: Delivery by CS was more frequent in the IBD cohort, and most elective CSs were obstetrically indicated. A dedicated IBD antenatal clinic providing closer monitoring and early detection of potential issues may help improve outcomes.

T helper cell immunity in pregnancy and influence on autoimmune disease progression

Pregnancy presents the maternal immune system with a unique immunological challenge since it has to defend against pathogens while tolerating paternal allo-antigens expressed by fetal tissues. T helper (Th) cells play a central role in modulating immune responses and recent advances have defined distinct contributions of various Th cell subsets throughout each phase of human pregnancy, while dysregulation in Th responses show association with multiple obstetrical complications. In addition to localized decidual mechanisms, modulation of Th cell immunity during gestation is mediated largely by oscillations in sex hormone concentrations. Aberrant Th cell responses also underlie several autoimmune disorders while pregnancy-induced changes in the balance of Th cell immunity has been shown to exert favorable outcomes in the progression Th1 and Th17 driven autoimmune conditions only to be followed by post-partal exacerbations in disease.

The Influence of Disease Activity on Pregnancy Outcomes in Women With Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis

BACKGROUND AND AIMS

Robust evidence regarding the impact of disease activity on pregnancy outcomes in women with inflammatory bowel disease [IBD] is crucial for both clinicians and patients in preparing a birth plan. We sought to perform a systematic review and meta-analysis to assess the pooled influences of disease activity on pregnancy outcomes in women with IBD.

METHODS

We searched MEDLINE, EMBASE and the COCHRANE library to identify articles comparing pregnancy outcomes between active and inactive IBD at the time of conception or during pregnancy. A meta-analysis was performed using a random-effects model to pool estimates and report odds ratios [ORs].

RESULTS

A total of 28 studies were identified as eligible for the meta-analysis. In women with active IBD, the pooled ORs for low birth weight [LBW], preterm birth, small for gestational age [SGA], spontaneous abortion and stillbirths were respectively 3.81 (95% confidence interval [CI] 1.81-8.02), 2.42 [95% CI 1.74-3.35], 1.48 [95% CI 1.19-1.85], 1.87 [95% CI 1.17-3.0] and 2.27 [95% CI 1.03-5.04] compared to women with inactive IBD. In the subgroup analysis based on disease type, women with active ulcerative colitis had an increased risk of LBW, preterm birth and spontaneous abortion. Women with active Crohn's disease had a higher risk of preterm birth, SGA and spontaneous abortion.

CONCLUSIONS

Active IBD during the periconception period and pregnancy is associated with an increased risk of adverse pregnancy outcomes. Our data suggest that pregnancy should be planned when the disease is quiescent, and continuous disease control is important even during pregnancy.

Inflammatory bowel disease and pregnancy: fertility, complications and treatment

Inflammatory bowel disease (IBD) is commonly diagnosed and treated in the young population. Therefore, it is common that women anticipating or undergoing pregnancy will have to cope with the additional burden of their IBD. Pregnancy in an IBD patient also presents challenges for the practitioner, in that the usual diagnostic and therapeutic armamentarium of potential tests and therapies is disrupted. This review covers the implications of IBD for fertility, pregnancy and offspring, and discusses the management of IBD in pregnancy.

[IBD and pregnancy: From conception to birth]

Inflammatory Bowel Diseases (IBD) are chronic conditions affecting young people in their reproductive age. Patient misinformation can be responsible for a self-imposed infertility as well as a suboptimal observance during pregnancy. The aim of this work was to review the influence of IBD and pregnancy on one another at each gestational stage and according to current literature. IBD activity is a major influential factor. In case of a well-controlled IBD, fertility won't be affected and pregnancy will take place without increase risk of complications. With the exception of thalidomide and methotrexate, most of treatments used in IBD are compatible with pregnancy and breastfeeding. Each flare should be optimally managed. Vaginal delivery is a safe option except for patients with active anoperineal lesions. Cesarean section should be systematically discuss in patient with ileal pouch-anal anastomosis.

New-onset ulcerative colitis in pregnancy associated to toxic megacolon and sudden fetal decompensation: Case report and literature review

Ulcerative colitis (UC) is a chronic inflammatory disease rarely arising during gestation. Because the available information is based on case reports or small retrospective studies, diagnosis may be difficult and treatment is still controversial. A case of toxic megacolon developing in late pregnancy associated to a sudden fetal decompensation is described. Diagnostic and clinical topics of acute UC onset in pregnancy are debated.A primipara, 34 years old, 33/0 weeks of gestation, was admitted with a diagnosis of preterm labor, associated to acute bloody diarrhea (up to 10 daily motions) and cramping abdominal pain. A diagnosis of new-onset early-stage UC was made by sigmoidoscopy. An intensive care regimen including hydrocortisone, antibiotics and parenteral nutrition was immediately started. Magnetic resonance imaging of maternal abdomen, fostered by the worsening patient conditions, evidenced dilatation of the entire colon and a severely hampered of fetal muscular tone.Toxic megacolon complicated by superimposed Clostridium difficile infection was associated to a sudden fetal decompensation diagnosed by chance during maternal abdominal magnetic resonance imaging. An emergency cesarean section was mandatory. According to a senior surgeon's decision, total colectomy was not immediately performed following cesarean section with reference to the absence of colonic perforation. We obtained a good short-term maternal outcome and an uncomplicated neonatal course. Counseling of those patients must be focused on timely and multidisciplinary intervention in order to improve the course of maternal disease and to prevent fetal distress.

[Cesarean section and perineal protection: CNGOF Perineal Prevention and Protection in Obstetrics Guidelines]

OBJECTIVE

The endpoint was to assess the interest of planned cesarean section in primary and secondary obstetrical perineal prevention.

METHODS

This is a review of the literature about the impact of the mode of delivery in urinary incontinence (UI), anal incontinence (AI), pelvic organ prolapse (POP), sexual disorders de novo or prior to delivery and history of obstetric anal sphincter injuries (OASI).

RESULTS

The studies about UI, AI and sexual disorders report a potential protective impact of cesarean section but with a possible selection bias and an inadequate comparability of the groups. Randomized trials do not report any protective effect of planned cesarean section for these 3 disorders. The literature about POP reports a higher risk for the women who delivered vaginally but still with a possible selection bias et there is no randomized trial for this outcome. About the secondary prevention of OASI, there is no evidence in the literature for a benefit of a systematic planned cesarean section for all women. For symptomatic women, the mode of delivery has to be discussed individually. In secondary prevention of UI, AI, POP and sexual disorders, there is no evidence in the literature for a benefit of planned cesarean section even if there is a history of surgical procedure for the disorder.

CONCLUSION

Planned cesarean section is not recommended in order to prevent primary or secondary obstetrical perineal disorders except for symptomatic OASI for whom an individual discussion about the mode of delivery is recommended.

Long-Term Disease Course and Pregnancy Outcomes in Women with Inflammatory Bowel Disease: An Indian Cohort Study

BACKGROUND

The literature on interaction between pregnancy and inflammatory bowel disease (IBD) is inconsistent, and there are no reports on this aspect from Asia. This study evaluated the impact both IBD and pregnancy have on each other in a large cohort of Indian patients.

METHODS

In total, 514 females with ulcerative colitis (UC) or Crohn's disease (CD) aged between 18 and 45 years attending IBD clinic, at our institute, from July 2004 to July 2013 were screened, and patients with data on pregnancy status were included (n = 406). Pregnancies were categorized as either before, after or coinciding with disease onset. Long-term disease course was ascertained from prospectively maintained records. Pregnancy and fetal outcomes were recorded from antenatal records or individual interviews.

RESULTS

Of 406 patients (UC: 336, CD: 70), 310 became pregnant (UC: 256, CD: 54), with a total of 597 pregnancies (UC: 524, CD: 73). More UC patients with pregnancies were in long-term remission than non-pregnant patients (56.7 vs. 43.4 %, p = 0.04). Long-term remission was less frequent in UC patients in whom pregnancy coincided with disease onset than patients with pregnancies before and after/pregnancy after the disease onset (41.4 vs. 62.5 %, p = 0.023). Pregnancies after the disease onset were associated with more cesarean sections and adverse fetal outcomes than pregnancies before disease onset in both UC and CD patients.

CONCLUSIONS

Long-term disease course in UC patients was better in pregnant as compared to non-pregnant patients. Among pregnant UC patients, disease course was worst when pregnancy coincided with disease onset. Pregnancy and fetal outcomes were worse in pregnancy after disease onset than pregnancy before disease onset.

Defining the Most Appropriate Delivery Mode in Women with Inflammatory Bowel Disease: A Systematic Review

INTRODUCTION

High cesarean section (CS) rates are observed in patients with inflammatory bowel disease (IBD), but limited data are available to support this decision. We conducted a comprehensive review to evaluate the most appropriate mode of delivery in women with IBD according to disease phenotype and activity, as well as surgical history.

MATERIALS AND METHODS

We searched MEDLINE (source PubMed) and international conference abstracts, and included all studies that evaluated digestive outcome after delivery in patients with IBD.

RESULTS

A total of 41 articles or abstracts were screened, and 18 studies were considered in this review, with sample sizes ranging from 4 to 229 patients and follow-up ranging from 2 months to 7.7 years. Pooled CS rates in patients without Perianal Crohn's disease (PCD), healed PCD or active PCD, were 27%, 43%, and 46%, respectively. Regarding the median rate of new PCD (3.0% [IQR, 1.5-11.5] versus 6.5% [0-19.7]) or PCD recurrence (13.5% [3.2-32.7] versus 45% [0-58]), no increase was observed in patients with vaginal delivery compared to CS, but for patients with an active disease, worsening of symptoms was noted in two-thirds of cases. Episiotomy, perianal tears, and instrumental delivery did not influence the incidence of PCD. In patients with ileal pouch anal anastomosis, uncomplicated vaginal delivery seemed to moderately influence pouch function, with no significant difference in terms of overall continence, daytime, or night-time stool frequency, or incontinence. However, these parameters seemed negatively impacted by a complicated vaginal delivery.

CONCLUSIONS

New long-term data from well-designed studies are needed, but our review suggests that systematic CS in patients suffering from IBD should probably be limited to women at risk of perineal tears and obstetric injuries, with an active PCD, or with ileal pouch anal anastomosis.

Managing inflammatory bowel disease in pregnancy: current perspectives

Inflammatory bowel disease (IBD) affects many women of childbearing age. The course of IBD is closely related to pregnancy outcomes with poorly controlled IBD increasing the risk of prematurity, low weight for gestation, and fetal loss. As such, women with IBD face complex decision making weighing the risks of active disease versus those of medical treatments. This review summarizes the current evidence regarding the safety and efficacy of IBD treatments during pregnancy and lactation aiming to provide up-to-date guidance for clinicians. Over 50% of women have poor IBD- and pregnancy-related knowledge, which is associated with views contrary to medical evidence and voluntary childlessness. This review highlights the effects of poor patient knowledge and critically evaluates interventions for improving patient knowledge and outcomes.

Perianal Crohn's disease results in fewer pregnancies but is not exacerbated by vaginal delivery

BACKGROUND

Despite a high prevalence of Crohn's disease in women of childbearing age, disease-related factors that may impact fertility and perianal Crohn's disease after delivery remain unclear.

METHODS

Self-administered questionnaires related to childbirth were completed by women with Crohn's disease referred to a single gastroenterology unit. A survival analysis was performed for statistical purposes.

RESULTS

A total of 184 patients were assessed, including 63 nulliparous women. The cumulative probabilities of having a child were 30%, 51% and 72% at the ages of 25, 30 and 35 years, respectively. Women with colonic disease, prior abdominal surgery and perianal disease were less likely to experience childbirth. After a median follow-up of 165 weeks post-delivery, the cumulative probabilities of fistulizing perianal Crohn's disease occurrence were 8%, 12% and 21% at 1, 2 and 5 years following childbirth, respectively. Contrary to a prior history of perianal Crohn's disease and colonic location, mode of delivery was not associated with perianal fistula. An episiotomy in the group of women with prior anal lesions did not result in a higher rate of fistula recurrence.

CONCLUSION

Perianal Crohn's disease is associated with fewer pregnancies, however perianal fistulas were less affected by obstetric events than their own natural history.

Emergency surgery for intestinal obstruction revealing ileal Crohn's disease (CD) during pregnancy

Few data are available regarding emergency surgery for Crohn's disease (CD) during pregnancy. A 22-year -old woman, at 26 weeks of pregnancy, was admitted for premature labour, intestinal obstruction and systemic inflammation. Biology and ultrasonography were not helpful; imaging was completed with a CT scan, which confirmed the mechanical ileal obstruction. The intestinal obstruction worsened and led to emergency surgery. An inflammatory stenosis of the terminal ileum with two fistulas was found. An ileal resection and ileostomy were performed. The pathological analysis of the resected specimen confirmed CD. The postoperative course was uneventful. The delivery of a baby with normal weight and status occurred at term (40 weeks of amenorrhoea). There have been only 10 case reports of intestinal complications revealing CD during pregnancy. The delay in diagnosis and adequate treatment led to significant maternal and fetal morbidity and mortality. This case suggests that intestinal surgery for CD is feasible during pregnancy and may be associated with a favourable outcome for the baby as well as for the mother.

The second European evidenced-based consensus on reproduction and pregnancy in inflammatory bowel disease

Trying to conceive and being pregnant is an emotional period for those involved. In the majority of patients suffering from inflammatory bowel disease, maintenance therapy is required during pregnancy to control the disease, and disease control might necessitate introduction of new drugs during a vulnerable period. In this updated consensus on the reproduction and pregnancy in inflammatory bowel disease reproductive issues including fertility, the safety of drugs during pregnancy and lactation are discussed.

Magnetic resonance enterography in pregnant women with Crohn's disease: case series and literature review

BACKGROUND

Evaluation of pregnant women with known or suspected Crohn's disease (CD) remains a challenge. Magnetic Resonance Enterography (MRE) is a promising diagnostic tool in these patients; however, the clinical data on MRE utilization in pregnancy is scarce. The aim of the study was to describe the experience with MRE in pregnant CD patients in a tertiary referral center.

METHODS

We retrospectively reviewed MRE studies performed in pregnant women with known or suspected CD that were performed between January 2007 and November 2012. Imaging findings, clinical management and outcome were extracted from patient's file and electronic records. Image quality was evaluated.

RESULTS

Ten studies of 9 patients were included. MRE protocol was modified to maximize maternal and fetal safety, and intravenous gadolinium was not used. In 7 patients, CD diagnosis was previously established; six were admitted with clinical symptoms consistent with CD exacerbation, and an additional patient with a recurrent groin abscess without apparent luminal symptoms. In all seven patients, imaging features consistent with active CD were detected; new penetrating complications were detected in 4 patients. Two patients underwent MRE for suspected CD which was not comforted by study results. The clinical management was significantly impacted by MRE results in all positive cases. The image quality of the fast MRE sequences obtained without gadolinium was satisfactory and allowed meaningful interpretation.

CONCLUSION

MRE with an adapted protocol for pregnancy is a reliable imaging modality to manage in pregnant women with known or suspected CD.

Management of inflammatory bowel disease in pregnancy

The management of inflammatory bowel disease (IBD) in women who are pregnant or contemplating pregnancy requires special considerations. Although many of the medications in IBD treatment are generally low risk, this is not the case for all agents, and substitution of medications or adjustments in dosage or dose timing may be needed. Furthermore, while women with IBD who have not had prior pelvic surgery are as likely to conceive as non-IBD counterparts, there is evidence to suggest that pregnancy outcomes may be worse in women with IBD, particularly if they have active disease during conception or pregnancy. Therefore, a thoughtful discussion between the patient and her healthcare team is critical to ensure awareness of the possible risks of pregnancy to the mother and her infant and how these risks can be minimized with a coordinated effort in counseling, monitoring and medication adherence.

[Obstetrical and gynecological relevance of inflammatory bowel disease]

INTRODUCTION

Inflammatory bowel disease may show a life long persistence, while female fertility is time-limited.

AIM

The aim of the authors was to obtain more knowledge about the obstetrical-gynecological aspects of this disorder.

METHODS

The authors evaluated 100 patients with inflammatory bowel disease and 100 healthy women with a self-composed questionnaire.

RESULTS

Menarche occurred significantly earlier in patients than in controls (p = 0,03). Either the activity of the disease, or the therapy itself may initiate irregularities in the menstrual cycle. Patients used contraceptives less frequently than controls (p = 0,002), and the time from family-planning to conception was longer in patients. Symptoms of bowel disease during pregnancy were not as severe as before and after pregnancy (p<0,001). Excess weight had a beneficial effect on symptoms during pregnancy (p = 0,042) and on the frequency of complications. Preterm birth and low birth weight were more frequent in newborns of patients (p = 0,019).

CONCLUSION

Pregnancy has positive effect on the symptoms of inflammatory bowel disease in case gestation occurs in a stable period of the inflammatory bowel disease.

Pregnancy related issues in inflammatory bowel disease: evidence base and patients' perspective

Inflammatory bowel disease (IBD) affects women of childbearing age and can influence fertility, pregnancy and decisions regarding breastfeeding. Women with IBD need to consider the possible course of disease during pregnancy, the benefits and risks associated with medications required for disease management during pregnancy and breastfeeding and the effects of mode of delivery on their disease. When indicated, aminosalicylates and thiopurines can be safely used during pregnancy. Infliximab and Adalimumab are considered probably safe during the first two trimesters. During the third trimester the placenta can be crossed and caution should be applied. Methotrexate is associated with severe teratogenicity due to its folate antagonism and is strictly contraindicated. Women with IBD tend to deliver earlier than healthy women, but can have a vaginal delivery in most cases. Caesarean sections are generally recommended for women with active perianal disease or after ileo-anal pouch surgery.While the impact of disease activity and medication has been addressed in several studies, there are minimal studies evaluating patients' perspective on these issues. Women's attitudes may influence their decision to have children and can positively or negatively influence the chance of conceiving, and their beliefs regarding therapies may impact on the course of their disease during pregnancy and/or breastfeeding. This review article outlines the impact of IBD and its treatment on pregnancy, and examines the available data on patients' views on this subject.

[Inflammatory bowel diseases: gynecological and obstetrical considerations]

Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis, are invalidating inflammatory affections, which evolve by relapse interrupted with clinical remission. Crohn's disease commonly affects young women in their reproductive years with a peak of incidence between 20 and 30. Infertility and sexual dysfunction are equivalent to that of the general population while they are increasing in patients with active IBD or after colorectal surgery. IBD are well controlled by medical treatments and the frequency of relapse during the pregnancy is similar to that of the non-pregnant IBD patients. The data concerning the risk of congenital malformations in IBD are contradictory. The risk of preterm delivery and low birth weight is significantly increased and correlated to the disease activity. When a medical treatment insures a quiescent disease before the pregnancy, it is advisable to continue it during the pregnancy because the benefits of controlled disease outweigh the risks of medication. IBD, possible perianal lesions and colorectal surgical interventions influence the mode of delivery, but the indication of caesarean section should primarily be governed by obstetric necessity. Preconceptional counseling seems desirable because of the risks during pregnancy, according to the disease activity, the surgical histories and the therapeutic agents.

Inflammatory bowel disease in pregnancy

Crohn’s disease and ulcerative colitis affect women in their child-bearing years. Family planning has come to be a common discussion between the gastroenterologist and the inflammatory bowel disease (IBD) patient. Disease control prior to desired conception and throughout pregnancy is the most important thing to keep in mind when caring for the IBD patient. Continued medical management during pregnancy is crucial in optimizing outcomes. Studies indicate that quiescent disease prior to conception infer the best pregnancy outcomes, similar to those in the general population. Active disease prior to and during pregnancy, can lead to complications such as pre-term labor, low birth weight, and small for gestational age infants. Although there are no definitive long term effects of pregnancy on IBD, there are some limited studies that suggest that it may alter the disease course. Understanding the literature and its limitations is important in the modern era of IBD care. Educating the patient and taking a team approach with the obstetrician will help achieve successful outcomes for mother and baby.

Inflammatory bowel disease in pregnancy

Crohn disease and ulcerative colitis commonly affect women in their childbearing years. Fortunately, advances in the field of inflammatory bowel disease have made successful pregnancy outcomes a reality for many women. These advances have led to family planning as a common discussion between gastroenterologists and inflammatory bowel disease patients. Common discussion topics are fertility, conception, medication safety, pregnancy, delivery, and breastfeeding although there are limited available data. Education and patient awareness have become vital factors in successful pregnancy outcomes.

Inflammatory bowel disease and pregnancy: an update

Women with inflammatory bowel disease have similar rates of conception to the general population unless they have had pelvic surgery. Once pregnant, regardless of disease activity, they have an increased risk of adverse pregnancy outcome and should be followed as high-risk obstetric patients. Most medications are compatible with pregnancy and lactation, as described in this article. Ideally, women should discuss their plans for pregnancy with their physician prior to conception so that risks and benefits can be reviewed, medications adjusted and healthcare maintenance updated. Once pregnant, a multidisciplinary team of gastroenterologists, obstetricians and pediatricians should help to ensure the best care for the mother and child.

Inflammatory bowel disease and pregnancy: report of two cases treated with infliximab and a review of the literature

Inflammatory bowel disease is relatively frequent in women of childbearing age. Disease management requires greater attention during this clinical condition because of potential risk of maternal-fetal complications. Infliximab has been shown to be safe during pregnancy and lactation, but reports in the literature are scarce. We report two cases of refractory Crohn's disease treated with infliximab with good results, in women. Both patients became pregnant during maintenance regimen and treatment was continued. The literature regarding pregnant patients with inflammatory bowel disease was reviewed.

Inflammatory bowel diseases and management considerations: fertility and pregnancy

Young women with inflammatory bowel disease (IBD) pose a unique set of challenges. These women and their treating physicians must make difficult choices in matters regarding conception, pregnancy, and breastfeeding. This review highlights recent evidence and management issues that arise when taking care of women with IBD in terms of fertility, outcomes, and medication safety in pregnancy and breastfeeding. Ultimately, treatment must be individualized for each patient based on the available evidence and the woman's preferences.

Management of the pregnant IBD patient

Women with inflammatory bowel disease (IBD) and the physicians who care for them must make difficult decisions on issues of conception, pregnancy, and breastfeeding with very limited and often contradictory information. This review provides the most current information on the inheritance of IBD, fertility, pregnancy outcomes, the management of disease during pregnancy, and the safety of medications in pregnancy and breastfeeding. We would like to emphasize that the information presented here must be individualized to the specific situation of each patient, their acceptance of risk, and their degree of disease severity.

Incidental Findings During Routine Antepartum Obstetrical Sonography

The standard for performing an antepartum obstetrical sonogram primarily involves the examination of the fetus; however, both the American Institute of Ultrasound in Medicine (AIUM) and American College of Radiology (ACR) guidelines suggest the evaluation of maternal structures as well. The authors present 35 incidental findings that were discovered on routine antepartum obstetrical sonography. These include abdominal wall, gastrointestinal, reproductive, urinary, and vascular anomalies in the maternal structures. A review of the literature demonstrates that many of these findings have clinical significance, which highlights the wisdom of the AIUM and ACR guidelines, and it also stresses the importance of seeking and reporting them.

Relapses of inflammatory bowel disease during pregnancy: in-hospital management and birth outcomes

BACKGROUND

There are few studies that describe the medical treatment and colitis response rates among patients with a severe relapse of inflammatory bowel disease (IBD) during pregnancy, and few studies of the effect of such a relapse on birth outcomes in these patients.

OBJECTIVES

To describe the treatment and response rates of severe colitis in pregnancy, and to assess the effects of a severe relapse of colitis during pregnancy on birth outcomes.

METHODS

We performed a case control study of pregnant patients with IBD hospitalized for a disease relapse at two large treatment centers between 1989 and 2001. Details of management of disease relapse and maternal and fetal outcomes were recorded.

RESULTS

Eighteen patients (11 ulcerative colitis, 6 Crohn's disease, 1 indeterminate colitis), mean age 28.6 yr (range 19-38) formed the study group; 41 age-matched pregnant IBD patients without disease relapse formed the control group. Study patients were hospitalized at a mean of 15.9-wk gestation (range 8-35) for a mean of 10.4 days (range 3-31). All 18 patients received IV hydrocortisone (mean dose 199 mg/day) and 7 patients (39%) either continued taking or were commenced on immunomodulators: IV cyclosporine (5 patients) and azathioprine/6-MP (3 patients). Fifteen patients (83%) had a clinical response to these medical treatments, 3 patients required colectomy. There were significant differences between study and control groups in gestation period (35.0 wk vs 38.7 wk, respectively, P= 0.0001) and birth weight (2,001 g vs 3,018 g, respectively, P < 0.0001).

CONCLUSIONS

Treatment with IV hydrocortisone and IV cyclosporine appears effective at inducing remission of colitis but their use must continue to be confined to severely ill patients being treated at specialized centers. Severe relapses of colitis during pregnancy increase the risk of preterm birth and low birth weight.

Surgical treatment of inflammatory bowel diseases and pregnancy

Ulcerative colitis (UC) and Crohn's disease (CD) affect women of reproductive age. Surgical intervention is often required. Therefore, the implications of disease treatment and pregnancy need to be understood. The standard surgery for UC is proctocolectomy, followed by ileal pouch anal anastomosis (IPAA). This review summarises the literature describing the effects of IPAA on gynaecologic and sexual health, fertility, pregnancy, labour and delivery. The emerging role of laparoscopic IPAA and the limited role of ileo-rectal anastomosis (IRA) are discussed. The experience with emergency surgery in pregnant women with ulcerative colitis is also presented. The literature explores two key issues of pregnancy in CD: the possible effect of pregnancy decreasing resection rates, and the optimal mode of delivery, especially in the setting of perianal CD. These two issues together with the available literature describing stoma function during pregnancy and the foetal outcome after surgical therapy are presented.

Review article: Reproduction in the patient with inflammatory bowel disease

BACKGROUND

Inflammatory bowel disease (IBD) affects mainly the young population. The effect of IBD and its treatment on fertility and pregnancy is therefore an important clinical consideration.

AIM

To review the best management of IBD in the reproductive and pregnant population.

METHODS

A MEDLINE and an EMBASE search were performed using mainly the search phrases 'pregnancy AND IBD,''sulphasalazine AND male fertility,''abdominal surgery AND female fertility,''AZA AND placenta' and 'infliximab AND pregnancy.' No language or date restrictions were placed. References of review articles were examined.

RESULTS

Overall male and female fertility are not affected by IBD. Sulphasalzine reduces male fertility. No other drugs used in IBD affect significantly fertility in humans. The risk of pregnancy-related complications and the disease behaviour during pregnancy depends mainly on disease activity at time of conception. Proactive treatment for maintenance of disease remission during gestation is recommended. Except for methotrexate, drugs used in IBD appear safe in pregnancy. Breast feeding should be encouraged.

CONCLUSION

The management of IBD in the young and pregnant population remains controversial because the literature comes mostly from retrospective studies. Further studies particularly large prospective trials are needed to guide clinicians in decision making.
