Safety of anti-TNF agents during pregnancy and breastfeeding in women with inflammatory bowel disease. Am J Gastroenterol 2013; 108:1426-38. [PMID: 23752881 DOI: 10.1038/ajg.2013.171] [Citation(s) in RCA: 89] [Impact Index Per Article: 8.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2013] [Accepted: 04/30/2013] [Indexed: 02/08/2023]
Abstract
OBJECTIVES Anti-tumor necrosis factor (TNF) drugs are an effective therapeutic option in patients with inflammatory bowel disease (IBD). However, data regarding their safety during pregnancy and breastfeeding are scarce. The aim of this study was to critically review available data on the safety of anti-TNF therapy during pregnancy and breastfeeding in women with IBD. METHODS Bibliographical searches (MEDLINE) up to January 2013. RESULTS The studies included provided data from 462 women with IBD exposed to anti-TNF agents during pregnancy. Although these drugs cross the placenta from the end of the second trimester, they are low-risk in the short term. The use of anti-TNF agents after the second trimester leads to intra-uterine exposure. An increase in infections has recently been observed in infants exposed to immunomodulators plus anti-TNF drugs in utero, thus raising concerns about the consequences for the development of the immune system. Accordingly, it has recently been suggested that anti-TNF drugs should be stopped during the second trimester. Certolizumab is a Fab fragment of an anti-TNF monoclonal antibody, and, therefore, it may not be necessary to stop it during pregnancy. Anti-TNF drugs have been detected in breast milk, although in miniscule amounts. Case reports do not suggest toxicity; however, the effects of exposure on the neonate merit further investigation. CONCLUSIONS Anti-TNF drugs can cross the placenta from the latter part of the second trimester of gestation, although they seem to be safe, at least in the short term. Miniscule amounts of anti-TNF drugs are transferred in breast milk; therefore, a deleterious effect of this exposure on the neonate, although unlikely, cannot be excluded.

Abstract
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.

Abstract
During human pregnancy, the maternal immune system develops and changes, providing protection for the growing placenta and fetus. These protective changes provide mechanisms allowing two genetically different individuals to interact with each other without allograft rejection. In addition to normal pregnancy, some pregnancies may develop under immunologic diseases, during which specific monitoring and medical treatments are essential. The aim of this current review is to provide information regarding the development of human placental function during pregnancy, the immunology of human pregnancy and the role of the placenta in providing the fetal tissue with antibodies (IgG and its subclasses 1-4), which are required for the passive immunization of the newborn. In addition, the available methods for the determination of placental function will be explored. Furthermore, immunologic diseases observed during pregnancy and the possible therapies for these diseases will be assessed.

Abstract
BACKGROUND Tumor necrosis factor (TNF)-α inhibitors are increasingly being used in inflammatory bowel disease (IBD). Because this chronic intestinal disorder often affects women of fertile age, it is essential to assess the effect of biologics on pregnancy outcome. METHODS We performed a systematic review of the English-language literature to investigate if treatment with TNF-α blockers during pregnancy in women with IBD increases the risk of spontaneous abortions, preterm delivery, stillbirth, low birth weight, congenital malformations, or risk of infections in the offspring. Of 552 articles and abstracts reviewed, 58 articles or abstracts with unique content were identified and included in this systematic review. However, most presentations were case reports or case series supplied by a limited number of observational studies. No randomized controlled studies were available. RESULTS TNF-α inhibitors do not seem to affect either outcome of pregnancy in mothers with IBD, or the outcome in the offspring (congenital malformations and immunosuppression). Further, recent data have not identified any increased risk of infections in the first year of life in the offspring of mothers who received biologics, even in combination with immunomodulators (thiopurines). CONCLUSIONS From the present systematic review, no association was found between administration of TNF inhibitors for IBD during pregnancy and adverse pregnancy outcome or congenital abnormalities. Further, no increased relative risk of infections has been reported in the first year of life in offspring of mothers who received biologics. Biologics should be discontinued during pregnancy solely if the IBD is in remission using the same stopping criteria as for patients with IBD in general, as uncontrolled activity of IBD may expose the mother and child to a risk greater than those only potentially coming from the use of TNF-α inhibitors. In such cases, inoculation of the offspring with live vaccines is contraindicated until the biologic agent is no longer detectable in the child's circulation.

Abstract
Although a great variety of new drugs have been introduced for the therapy of inflammatory bowel diseases so far, a definite cure of the disease is still out of scope. An anti-inflammatory approach to induce remission followed by maintenance therapy with immunosupressants is still the mainstay of therapy. Thiopurines comprising azathioprine and its active metabolite mercaptopurine as well as tioguanine, are widely used in the therapy of chronic active inflammatory bowel disease (IBD). Their steroid sparing potential and efficacy in remission maintenance are out of doubt. Unfortunately, untoward adverse events are frequently observed and may preclude further administration or be life threatening. This review will focus on new aspects of thiopurine therapy in IBD, its efficacy and safety.

Abstract
OBJECTIVES The safety of thiopurines and anti-tumor necrosis factor-α (TNF-α) drugs during pregnancy remains controversial, as the experience with these drugs in this situation is limited. Our aim is to assess the safety of thiopurines and anti-TNF-α drugs for the treatment of inflammatory bowel disease (IBD) during pregnancy. METHODS Retrospective, multicenter study in IBD patients. Pregnancies were classified according to the therapeutic regimens during pregnancy or during the 3 months before the conception: non-exposed group, pregnancies exposed to thiopurines alone (group A), and pregnancies exposed to anti-TNF-α drugs (group B). An unfavorable Global Pregnancy Outcome (GPO) was considered if pregnancy developed with obstetric complications in the mother and in the newborn. RESULTS A total of 187 pregnancies in the group A, 66 pregnancies in the group B, and 318 pregnancies in the non-exposed group were included. The rate of unfavorable GPO was different among the three groups (31.8% in non-exposed group, 21.9% in group A, and 34.8% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). The rate of pregnancy complications was similar among the three groups (27.7% in non-exposed, 20.9% in group A, and 30.3% in group B). The rate of neonatal complications was different among the three groups (23.3% in non-exposed group, 13.9% in group A, and 21.2% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). In the multivariate analysis, the treatment with thiopurines (odds ratio = 0.6; 95% confidence interval = 0.4-0.9, P = 0.02) was the only predictor of favorable GPO, whereas maternal age >35 years at conception was the only predictor of unfavorable GPO. The treatment with anti-TNF-α drugs was not associated with an unfavorable GPO. CONCLUSION The treatment with thiopurines and anti-TNF-α drugs does not seem to increase the risk of complications during pregnancy and does seem to be safe for the newborn.

Abstract
PURPOSE Treatment of ulcerative colitis with drugs during pregnancy potentially may harm the mother and the unborn child. Granulocytapheresis depletes elevated/activated myeloid lineage leucocytes as sources of inflammatory cytokines. We were interested in the safety and efficacy of granulocytapheresis in patients who had ulcerative colitis flare up during pregnancy. METHODS Three pregnant cases with active ulcerative colitis received Adacolumn granulocytapheresis, up to 10 sessions within 3-6 weeks. Case 1: a 33-year-old woman with left-sided colitis and bloody diarrhoea 7-9 times/day showed loss of mucosal vascular patterns, and contact bleeding from the rectum to the sigmoid colon. Case 2: a 36-year-old woman with pancolitis and bloody diarrhoea 6-8 times/day had loss of mucosal vascular patterns and pus from the rectum to the sigmoid colon. Case 3: a 36-year-old woman with pancolitis and diarrhoea 4-5 times/day (first episode) had erosions and pus in the mucosa from the rectum to the transverse colon. RESULTS Colitis flare was in weeks 5, 13 and 22 of pregnancy in cases 1, 2, 3, respectively. The corresponding granulocytapheresis sessions were 5, 7, and 10, reflecting an increasing trend with the pregnancy week. Patients 1 and 2 achieved complete remission, patient 3 achieved clinical remission. CONCLUSION In these three cases with active ulcerative colitis during pregnancy, granulocytapheresis as a non-pharmacologic treatment was effective and safe. In case 3 that did not respond well to the initial granulocytapheresis sessions, a moderate dose of prednisolone enhanced the efficacy of granulocytapheresis and tapering of prednisolone shortly after administration was not associated with relapse.

Abstract
Inflammatory bowel disease (IBD) comprises two main types, namely, Crohn's disease (CD) and ulcerative colitis (UC). The etiology of IBD is not clear, and there is no effective cure so far. Currently available agents for IBD mainly consist of traditional drugs (including aminosalicylates, corticosteroids, and immunosuppressants) and new biological preparations (mainly TNF-α monoclonal antibody). The treatment of IBD evolves with the progress of clinical research and pharmaceutical techniques, such as new dosage forms, different routes of administration, and the application of new biological preparations. This article reviews recent progress in the treatment of IBD.

Abstract
The efficacy of thiopurine treatment in the induction, and especially maintenance, of remission in inflammatory bowel disease is well proven; however, it is associated with side effects in both medium and long-term use. The potential harmful effects may be anticipated and minimised by due diligence prior to commencing these drugs followed by close monitoring of haematological and biochemical parameters once started. Careful clinical examination and history taking are also essential. Affected patients are expected to lead lives that include travel, employment and pregnancy - the implications of continued thiopurine therapy in such patients are discussed.

Abstract
INTRODUCTION The inflammatory bowel diseases (IBD) are chronic, idiopathic, inflammatory conditions of the gastrointestinal tract, that peak in incidence during the reproductive years. Therefore, the safety of IBD medications during pregnancy and lactation is of significant interest to patients. Unfortunately, the current pregnancy labeling used by the United States Food and Drug Association (FDA) is often misinterpreted and may mislead healthcare providers and their patients to believe that risk increases from Category A to B to C to D to X, which in fact, is not the case. In addition, the FDA categories do not always distinguish between risks based on human versus animal data, or between differences in frequency, severity, and type of fetal developmental toxicities. AREAS COVERED This article provides an in-depth review of the available safety data during pregnancy and lactation for the more potent immunosuppressants used to treat IBD: the immunomodulators and biologics. It also includes the authors' expert opinions on the use of these medications during these critical periods. EXPERT OPINION The benefit-to-risk ratio for most immunomodulators and biologics used in the treatment of IBD favors medication continuation during pregnancy. Certain immunomodulators, however, can cause extreme fetal harm and should be used with caution. While human safety data regarding teratogenesis and some data on pregnancy outcomes exist for most IBD medications, long-term follow-up studies of children and young adults exposed to these drugs in utero are lacking. These studies are needed to determine if these drugs are of sufficiently low risk to be considered safe.

Abstract
BACKGROUND AND AIMS Inflammatory bowel disease (IBD) is a chronic disease affecting mainly young people in their reproductive years. IBD therefore has a major impact on patients' family planning decisions. Management of IBD in pregnancy requires a challenging balance between optimal disease control and drug safety considerations. This article aims to provide a framework for clinical decision making in IBD based on review of the literature on pregnancy-related topics. METHODS Medline searches with search terms 'IBD', 'Crohn's disease' or 'ulcerative colitis' in combination with keywords for the topics fertility, pregnancy, congenital abnormalities and drugs names of drugs used for treatment of IBD. RESULTS IBD patients have normal fertility, except for women after ileal pouch-anal anastomosis (IPAA) and men under sulfasalazine treatment. Achieving and maintaining disease remission is a key factor for successful pregnancy outcomes in this population, as active disease at conception carries an increased risk of preterm delivery and low birth weight. Clinicians should discuss the need for drug therapy to maintain remission with their patients in order to ensure therapy compliance. Most IBD drugs are compatible with pregnancy, except for methotrexate and thalidomide. If possible, anti-TNF therapy should be stopped by the end of the second trimester and the choice of delivery route should be discussed with the patient. CONCLUSIONS Disease control prior to conception and throughout pregnancy is the cornerstone of successful pregnancy management in IBD patients.

Abstract
Several studies have reported on the association between inflammatory bowel disease (IBD) and adverse pregnancy outcomes, such as preterm birth. The exact mechanisms of action are unclear; however, several pathways and processes are involved in both IBD and pregnancy that may help explain this. In this review, we discuss the immune system's T helper cells and human leukocyte antigens, inflammation, its function, and the role of Toll-like receptors (TLRs), NOD-like receptors (NLRs), and prostaglandins in the inflammatory response. For each of these topics, we consider their involvement in IBD and pregnancy, and we speculate as to how they can lead to preterm birth. Finally, we review briefly corticosteroids, biologic therapies, and immunosuppressants for the treatment of IBD, as well as their safety in use during pregnancy, with special focus on preterm birth.

Abstract
The relapse rate of multiple sclerosis (MS) is typically reduced during late pregnancy but increases in the postpartum period. The reasons for the increased postpartum activity are not entirely clear, but factors such as the abrupt decrease in oestrogen levels immediately after the delivery and the loss of the immunosuppressive state of pregnancy are likely of importance. There is a general view that MS does not affect the course or outcome of pregnancy.

Abstract
Thrombocytopenia is a common finding in pregnancy, occurring in approximately 7-10% of pregnancies. It may be a diagnostic and management problem, and has many causes, some of which are specific to pregnancy. Although most cases of thrombocytopenia in pregnancy are mild, and have no adverse outcome for either mother or baby, occasionally a low platelet count may be part of a more complex disorder with significant morbidity and may be life-threatening. Overall, about 75% of cases are due to gestational thrombocytopenia, 15-20% secondary to hypertensive disorders; 3-4% due to an immune process, and the remaining 1-2% made up of rare constitutional thrombocytopenias, infections and malignancies. In this review, a diagnostic approach to investigating thrombocytopenia in pregnancy is presented, together with antenatal, anaesthetic and peri-natal management issues for mother and baby, followed by a detailed discussion on the specific causes of thrombocytopenia and the management options in each case.

Abstract
A 26 year old woman with ulcerative colitis was treated with regular infliximab (IFX) infusions until gestation week 31, and gave birth to a healthy child at gestation week 37. Maternal IFX trough level was relatively high during the course of pregnancy. In the infant, therapeutic level of IFX was detectable at week 16 after birth, but not at reassessment at week 28. Anti-IFX antibodies were consistently below the detection limit in the patient and in the child. This case illustrates that IFX is transferred through the placenta to the embryo, and may result in therapeutic drug levels in the newborn child despite IFX discontinuation in third trimester 6 weeks prior to delivery. The half life of IFX appeared markedly longer in infants as compared to adults. The safety of IFX beyond the first trimester is unknown, and this case highlights the need for further investigations of maternal transfer of IFX as well as the risks associated with IFX administrations in the second and third trimester.

Abstract
INTRODUCTION Limited data suggest the absence of infliximab in breast milk, thereby implying the safety of this drug during breast-feeding. We aimed to re-evaluate the presence of infliximab in breast milk of nursing IBD patients. METHODS Serum and breast milk were obtained post-partum from 3 breast-feeding patients with Crohn's disease before and after re-initiation of infliximab. ELISA assay was employed to measure infliximab level in maternal serum and in breast milk. The level of infliximab was also measured in breast milk of a control group of 8 nursing healthy mothers. RESULTS Infliximab was undetectable in breast milk prior to the first infusion and was also not measurable in 8 lactating women not exposed to infliximab. Infliximab levels in breast milk rose up to 101ng/ml within 2-3days of the infusion. These levels of infliximab in breast milk were roughly 1/200th of the level in blood. CONCLUSIONS In contrast with prior reports, infliximab can be detected in the breast milk of nursing mothers. The miniscule amounts of infliximab transferred in breast milk are unlikely to result in systemic immune-suppression of the infant. Nonetheless, local effects of this exposure on the neonates' intestine and potential immune sensitization or tolerization towards the drug can not be excluded and merit further investigations.

Abstract
It has long been known that pregnancy and childbirth have a profound effect on the disease activity of rheumatic diseases. For clinicians, the management of patients with RA wishing to become pregnant involves the challenge of keeping disease activity under control and adequately adapting drug therapy during pregnancy and post-partum. This article aims to summarize the current evidence on the evolution of RA disease activity during and after pregnancy and the use of anti-rheumatic drugs around this period. Of recent interest is the potential use of anti-TNF compounds in the preconception period and during pregnancy. Accumulating experience with anti-TNF therapy in other immune-mediated inflammatory diseases, such as Crohn's disease, provides useful insights for the use of TNF blockade in pregnant women with RA, or RA patients wishing to become pregnant.

Abstract
Anti-tumor necrosis factor (TNF) therapy to treat inflammatory bowel disease has been available for more than a decade. Although extensive data on the outcome of anti-TNF therapy from individual clinical trials and patient cohorts are available, integrated guidance on the best use of such therapy to achieve optimal clinical outcomes when managing patients with luminal Crohn's disease is lacking. This review combines published data to establish practical strategies for anti-TNF therapy with respect to effective and safe timing of introduction, use of concurrent immunosuppressive therapy, dose escalation, managing relapse, changing drugs, pregnancy and breast feeding, and stopping drug treatment.

Abstract
We describe a woman treated with cyclosporine after renal transplantation who commenced breastfeeding of her newborn infant. The child had no apparent clinical adverse effects to cyclosporine. To confirm the safety of breastfeeding and guide the patient and her clinician, cyclosporine concentrations in maternal blood, breast milk, and infant blood were measured. Maternal cyclosporine concentration (1-hour postdose) was 49 μg/L, and the breast milk cyclosporine concentration (2-hour postdose) was 46 μg/L. Infant cyclosporine blood concentration shortly after breastfeeding was undetectable (<10 μg/L). Analysis revealed that the estimated infant exposure to cyclosporine via breast milk was minimal and provided reassurance to continue breastfeeding in this case.

Abstract
Anti-TNFα treatments have modified the medical care, the course and the quality of life of the patients with autoimmune rheumatic, cutaneous or bowel inflammatory diseases. On the other hand, these treatments may have potential severe side effects during pregnancy (congenital malformations, fetal infections). Actually, many pregnancies have been reported during anti-TNFα exposures, with good maternal and neonatal outcomes. The introduction or the discontinuation of these treatments will always have to be discussed with the specialist of the chronic disease and, ideally, during a preconceptional counselling. In gynecology, anti-TNFα drugs may offer a new safe and effective approach to treating patients with recurrent miscarriages or unexplained or failed in vitro fertilization cycles. On the other hand, these treatments significantly increase the risk for serious infections or viral reactivations and may promote gynaecological malignancies. An adapted gynaecological survey is necessary.

Abstract
BACKGROUND Neither conceptions and pregnancy outcomes nor the safety of medications for childbearing inflammatory bowel disease (IBD) patients has been investigated in Asia. The aim of this study is to analyse conception and pregnancy outcomes of Japanese female IBD patients. METHODS We conducted a retrospective cohort study of pregnant IBD patients at 6 institutions. The incidences of abortion, Caesarean delivery, low birth weight (LBW) (<2500g), and congenital malformation were analysed in these patients. Risk factors associated with adverse outcomes in IBD patients were also assessed. RESULTS A total of 325 patients experienced 534 conceptions. Among these, 303 conceptions (57%) were observed during/after disease onset. Although conceptions and pregnancy outcomes after disease onset were comparable to the observed levels prior to disease onset in UC patients, the incidences of spontaneous abortion (OR 5.3; 95%CI 1.1-25.0) and Caesarean delivery (OR 4.8; 95%CI 1.5-15.0) were significantly higher in Crohn's disease (CD) patients whose conceptions occurred after disease onset compared to CD patients whose conceptions occurred before disease onset. The incidences of spontaneous abortion, LBW, and Caesarean delivery were higher in CD patients who had a history of surgery for perianal lesions than in those who did not have perianal lesions or who had ulcerative colitis (UC). In the IBD patients studied after disease onset, independent risk factors for spontaneous abortions included a history of previous treatment for sterility (OR 2.9; 95%CI 1.2-7.0). Independent risk factors for Caesarean operation (OR 4.1, 95% CI: 1.7-10.1) and LBW (OR 3.5, 95% CI: 1.3-9.1) included a history of bowel resection for the treatment of IBD. Congenital malformation was not associated with the factors of type of disease, smoking, and previous surgery. CONCLUSION In Japanese UC patients, conception and pregnancy outcomes after disease onset were comparable to the outcomes observed prior to disease onset, whereas CD appeared to be associated with adverse outcomes. Caesarean operation and LBW were more frequently observed in CD patients who had a history of surgery for perianal lesions and bowel resection.

Abstract
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.

Abstract
BACKGROUND Typically, inflammatory bowel disease (IBD) patients are in their reproductive years, raising questions about safely using antitumour necrosis factor antibodies like infliximab (IFX) during pregnancy. IgG antibodies naturally cross the placenta, especially during the last trimester. To prevent foetal intra-uterine exposure, stopping IFX treatment at gestational week 30 is recommended. However, whether this limits intra-uterine and early postnatal IFX exposure is unestablished. AIM To determine the intra-uterine exposure to IFX following maternal treatment with IFX. METHODS Four pregnant IBD patients intentionally continued IFX during pregnancy. IFX levels were assessed in newborns' cord blood and the mothers' peripheral blood at delivery. The children's development during the first 3-6 months, infections, vaccine reactions and antibody responses to vaccinations against Haemophilus influenzae type b and Pneumococcus were assessed. RESULTS The patients stopped IFX therapy at gestational week 21, 26, 26 and 30, respectively. In three infants, therapeutic IFX levels were present in cord blood at levels of 5.5-13.7 μg/mL and were two- to three-fold higher than in the peripheral blood of their mothers. During the 3- to 6-month follow-up, the children developed normally without signs of infections or allergic reactions, and had normal antibody titres after routine childhood vaccinations. CONCLUSION The use of IFX until gestational week 30 leads to foetal intra-uterine exposure to IFX at levels that exceed those in the mothers' peripheral blood. Although no short-term complications were detected, the high IFX levels observed in newborns raise concerns about unknown effects of IFX on the developing immune system.

Abstract
Behçet's disease is a multisystemic disease of unknown origin characterized by a recurrent bipolar aphtosis (oral and genital) associated with vascular, digestive or articular symptoms. Gynecologists can be faced to this disease at any time of the life of their patients, including during the pregnancy. Given that the first demonstrations of the disease can be genital, they are in the front line to evoke this diagnosis. They thus have to know the main characteristics of the disease to make the diagnosis and to organize a multidisciplinary management. During pregnancy, the treatment of the disease is to be adapted to avoid teratogenic drugs, and adapt the doses of the treatment.

Abstract
In the last 10 years, anti-tumor necrosis factor (TNF)-α therapy has become a cornerstone in the management of autoimmune diseases. Clinical trial data have consistently found that infliximab, adalimumab, and recently certolizumab pegol offer therapeutic benefits to patients with inflammatory bowel diseases (Crohn's disease and ulcerative colitis). Recent understanding on how these monoclonal antibodies evoke changes at the physiological and molecular levels have provided insights into disease pathogenesis and helped to identify new targets for future drug therapy. With increased experience in the use of these anti-TNF-α antibodies the long-term safety data, use in pregnancy have become available. This article provides an overview of the current knowledge regarding anti-TNF-α therapies for clinicians caring for patients with Crohn's disease and ulcerative colitis.
