Abstract
Inflammatory Bowel Disease (IBD) presents distinct challenges during pregnancy due to its influence on maternal health and pregnancy outcomes. This literature review aims to dissect the existing scientific evidence on pregnancy in women with IBD and provide evidence-based recommendations for clinical management. A comprehensive search was conducted across scientific databases, selecting clinical studies, systematic reviews, and other pertinent resources. Numerous studies have underscored an increased risk of complications during pregnancy for women with IBD, including preterm birth, low birth weight, neonates small for gestational age, and congenital malformations. Nevertheless, it's evident that proactive disease management before and throughout pregnancy can mitigate these risks. Continuation of IBD treatment during pregnancy and breastfeeding is deemed safe with agents like thiopurines, anti-TNF, vedolizumab, or ustekinumab. However, there's a call for caution when combining treatments due to the heightened risk of severe infections in the first year of life. For small molecules, their use is advised against in both scenarios. Effective disease management, minimizing disease activity, and interdisciplinary care are pivotal in attending to women with IBD. The emphasis is placed on the continual assessment of maternal and infant outcomes and an expressed need for further research to enhance the understanding of the ties between IBD and adverse pregnancy outcomes.

Abstract
In recent years, we have faced an increasing incidence of inflammatory bowel disease (IBD), especially among young people, affecting them during their reproductive years. The paucity of data and reduced knowledge regarding the evolution of the disease during pregnancy and the adverse effects of the therapy on the mother and infant increase voluntary childlessness in this group of patients. Depending on the type of IBD, severity and surgical or medical management, this can negatively affect the pregnancy. C-sections and the risk of low-birth-weight babies are higher in women with IBD, independent of active/inactive disease, while preterm birth, stillbirth and miscarriage are associated with disease activity. In the last period, medicinal therapy has evolved, and new molecules have been developed for better control of the lesions, but the effect on pregnancy and breastfeeding is still controversial. We conducted this review by studying the literature and recent research in order to have a better image of the practical management of IBD during pregnancy.

Sulfasalazine exposure during pregnancy and lactation induces alterations in reproductive behavior in adult female rat offspring. Life Sci 2022; 293:120303. [PMID: 35051419 DOI: 10.1016/j.lfs.2022.120303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 12/23/2021] [Accepted: 01/04/2022] [Indexed: 11/21/2022]
Abstract
AIMS Sulfasalazine (SAS) is the first line drug in the treatment of chronic inflammatory bowel diseases in pregnant women. SAS and its metabolites cross the placenta and can be transferred through the milk. However, the long-term consequences to the reproductive system of offspring from dams exposed to SAS have not yet been studied. Thus, our study investigated the effects of SAS treatment during gestational and lactational periods on maternal care in F0 and reproductive outcomes in F1 females. MAIN METHODS Wistar female rats (n = 10/group) received 300 mg/kg/day of SAS dissolved in carboxymethyl cellulose (CMC), by gavage, from gestational day 0 to lactation day 21 and 3 mg/kg/day of folic acid during gestation. The control group received CMC only. On PND 21, the female pups were selected for reproductive evaluation at different time points: infancy and adulthood. The reproductive parameters evaluated were installation of puberty (vaginal opening and first estrus), estrous cyclicity, reproductive organs weight, histological analysis of the ovary follicles and uterus, analysis of oxidative stress in ovarian tissue, reproductive behavior (sexual and maternal), and fertility. KEY FINDINGS SAS treatment decreased the retrieving behavior in F0 females. The F1 females presented an increase in the lordosis score, frequency of lordosis of magnitude 3, and lipid peroxidation of ovarian tissues in both infancy and adult life. SIGNIFICANCE The SAS effects observed in the current study represent a relevant concern for public health, as they demonstrated that treatment with SAS compromised the maternal motivation of dams and induced reproductive alterations in F1 females.

Abstract
Introduction: The peak age of diagnosis of inflammatory bowel disease (IBD) occurs during childbearing years, therefore management of IBD during pregnancy is a frequent occurrence. Maintenance of disease remission is crucial to optimize pregnancy outcomes, and potential maternal or fetal toxicity from medications must be balanced against the risks of untreated IBD.Areas covered: This review summarizes the literature on safety and use of medications for IBD during pregnancy and lactation.Expert opinion: 5-aminosalicylates, corticosteroids and thiopurines are safe for use during pregnancy, while methotrexate and tofacitinib should only be used with extreme caution. Anti-TNF agents (except certolizumab), vedolizumab, ustekinumab and tofacitinib readily traverse the placenta via active transport, therefore theoretically may affect fetal development. Certolizumab only undergoes passive transfer across the placenta, thus has markedly lower cord blood levels making it likely the safest biologic agent for infants. There is reasonable evidence to support the safety of anti-TNF monotherapy and combination therapy during pregnancy and lactation. Vedolizumab and ustekinumab are also thought to be safe in pregnancy and lactation, while tofacitinib is generally avoided due to teratogenic effects in animal studies.

Abstract
Chronic rheumatic diseases often occur in women of reproductive age, and the effect rheumatic disease has on pregnancy varies depending on the condition. Medical management of rheumatic diseases during pregnancy may prevent joint or organ damage and minimize the adverse effects of the disease itself on pregnancy outcomes. Each patient requires individual assessment to control disease activity while minimizing or avoiding medications with potential maternal or fetal toxicity. An open discussion with shared decision making between patients, obstetricians, rheumatologists, and pharmacists is imperative to create an individualized treatment plan that meets patients' goals. This article will review the current literature for use of disease modifying antirheumatic drugs and biologics during pregnancy and lactation, providing health care professionals with the most up-to-date information available.

Abstract
BACKGROUND Most anti-tumour necrosis factor (anti-TNF) agents are transferred across the placenta and may increase paediatric susceptibility to infections. AIMS To assess the risk of paediatric infections after maternal anti-TNF treatment. METHODS Population-based cohort study in Denmark, Finland and Sweden 2006-2013 in which 1027 children born to women with rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis or inflammatory bowel disease, treated with anti-TNF, and 9346 children to women with non-biologic systemic treatment, were compared to 1 617 886 children of the general population. Children were followed for 3 years. RESULTS Adjusted by maternal age, parity, smoking, body mass index, country and calendar year, the incidence rate ratios with 95% confidence interval (CI) for hospital admissions for infection in the first year were 1.43 (1.23-1.67) for anti-TNF and 1.14 (1.07-1.21) for non-biologic systemic treatment, and 1.29 (1.11-1.50) and 1.09 (1.02-1.15), respectively, when additionally adjusting for adverse birth outcomes. There was a slight increase in antibiotic prescriptions in the second year for anti-TNF, 1.19 (1.11-1.29), and for non-biologic systemic treatment, 1.10 (1.07-1.13). There was no difference among anti-TNF agents, treatment in the third trimester, or between mono/combination therapy with non-biologic systemic treatment. CONCLUSIONS Both anti-TNF and non-biologic systemic treatment were associated with an increased risk of paediatric infections. However, reassuringly, the increased risks were present regardless of treatment in the third trimester, or with combination treatment, and were not persistent during the first 3 years of life. Our findings may indicate a true risk, but could also be due to unadjusted confounding by disease severity and healthcare-seeking behaviour. This may in turn shift the risk-benefit equation towards continuation of treatment even in the third trimester.

Abstract
OBJECTIVES The main objective of this study was to determine whether the DNA methylation profile of children born to mothers with rheumatoid arthritis (RA) is different from that of children born to mothers from the general population. In addition, we aimed to determine whether any differences in methylation are associated with maternal RA disease activity or medication use during pregnancy. METHODS For this study, genome-wide DNA methylation was measured at cytosine-phosphate-guanine (CpG) sites, using the Infinium Illumina HumanMethylation 450K BeadChip, in 80 blood samples from children (mean age=6.8 years) born to mothers with RA. As controls, blood samples from 354 children (mean age=6.0 years) from the population-based Generation R Study were used. Linear mixed models were performed to investigate differential methylation between the groups, corrected for relevant confounders. RESULTS A total of 147 CpGs were differentially methylated between blood samples of children born to mothers with RA and the control blood samples. The five most significantly associated CpGs were cg06642177, cg08867893, cg06778273, cg07786668 and cg20116574. The differences in methylation were not associated with maternal RA disease activity or medication use during pregnancy. CONCLUSIONS DNA methylation at 147 CpGs differed between children born to mothers with RA and children born to mothers from the general population. It remains unknown whether the identified associations are causal, and if so whether they are caused by the disease or treatment. More research, including replication of these results, is necessary in order to strengthen the relevance of our findings for the later-life health of children born to mothers with RA.

Abstract
The frequency of diagnosis of inflammatory bowel disease (IBD) has increased in younger populations. For this reason, pregnancy in patients with IBD is a topic of interest, warranting additional focus on disease management during this period. The main objective of this article is to summarize the latest findings and guidelines on the management of potential problems from pregnancy to the breastfeeding stage. Fertility is decreased in patients with active IBD. Disease remission prior to conception will likely decrease the rate of pregnancy-related complications. Most of the drugs used for IBD treatment are safe during both pregnancy and breastfeeding. Two exceptions are methotrexate and thalidomide, which are contraindicated in pregnancy. Anti-tumor necrosis factor agents are not advised during the third trimester as they exhibit increased transplacental transmission and potentially cause immunosuppression in the fetus. Radiological and endoscopic examinations and surgical interventions should be performed only when absolutely necessary. Surgery increases the fetal mortality rate. The delivery method should be determined with consideration of the disease site and presence of progression or flare up. Treatment planning should be a collaborative effort among the gastroenterologist, obstetrician, colorectal surgeon and patient.

Abstract
Inflammatory bowel disease (IBD) usually affects women during their reproductive years and many concerns arise among these young patients. Pre-pregnancy consultation with a multi-disciplinary team is very important. The team should make patients aware of the critical importance of ensuring that conception occurs during a period of disease remission. Conception during an IBD flare-up results in disease activity or even exacerbates disease in two-thirds of women. Exacerbation of the disease is associated with increased frequency of maternal and fetal complications. Drug therapy constitutes a considerable source of patient anxiety but most drugs used for treating IBD are considered safe. Therefore, continuing pharmacological therapy during pregnancy is necessary to maintain disease control. Optimization of pre-conception nutritional status and smoking cessation are also emphasized. The general guideline for most patients, except for active perianal disease patients, is to aim for vaginal delivery in the absence of obstetric contraindications. Consistent, ongoing follow-up, as detailed in this review, should allay the anxieties and fears surrounding continuing immunosuppressive drugs during pregnancy, allowing each patient to attain the optimal conditions for achieving her goal of holding a healthy baby.

Abstract
Rheumatoid arthritis (RA), a chronic autoimmune inflammatory disease of synovial joints, can lead to chronic pain and structural joint damage, as well as other organ involvement, especially if not adequately controlled. Because it can affect women in their reproductive years, care of pregnant women with RA requires a delicate balance of maintaining disease control while limiting potential toxicity to the fetus and neonate. While most women experience a substantial improvement in disease activity during pregnancy, for some women their RA remains active. It can even manifest itself for the first time during pregnancy or early in the post-partum period. Optimizing disease control prior to conception is key, but utilizing disease-modifying treatments effectively and safely throughout pregnancy and lactation requires open dialogue and shared decision making. This review provides evidence-based recommendations for use of disease-modifying antirheumatic drugs (DMARDs) and biologic response modifiers to guide rheumatologists in their care of pregnant and lactating women with RA and serves as a guide to counsel male patients with RA on family planning decisions.

Abstract
IBD often affects patients during their peak reproductive years. Several drugs are available for the treatment of IBD and new drugs are continuously in the pipeline. As long-term administration of medications is often necessary, the safety of drug therapy during pregnancy and breast-feeding needs to be considered in daily clinical practice. The aim of this Review is to summarize the latest information concerning the safety of medications used to treat IBD during pregnancy and lactation, as well as their effect on fertility. Although only thalidomide and methotrexate are absolutely contraindicated during pregnancy and breast-feeding, alternatives to ciprofloxacin, natalizumab and sodium phosphate should also be considered for pregnant women. Breast-feeding is also discouraged while on treatment with ciclosporin, metronidazole and ciprofloxacin. However, therapy with 5-aminosalicylic acid preparations, glucocorticoids, thiopurines and TNF inhibitors are acceptable during pregnancy and lactation. Pregnant women who have symptomatic IBD or who require therapy should have the opportunity to discuss any associated risks to their pregnancy and infant with the appropriate consultants. By ensuring that the patient and her family are informed, the clinical outcome might be optimized.

Abstract
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.

Abstract
Pregnancy can create a challenge for physicians caring for women with rheumatic diseases. For many women with rheumatoid arthritis (RA), pregnancy can provide a reprieve from long-term joint pain and inflammation, but others will not experience remission and will continue to need medication. Systemic lupus erythematosus (SLE) may remain quiet in some women, but in others may become more aggressive during pregnancy, putting both mother and foetus at risk. Women with limited scleroderma can do remarkably well, but scleroderma renal crises can be difficult to manage. A third of pregnancies in women with antiphospholipid syndrome (APS) may be refractory to our best therapy. In general, active inflammation from rheumatic diseases poses a stronger threat to the well-being of both mother and foetus than many immunosuppressant medications. Therefore, continued immunosuppression with the least risky medications will allow for the most optimal pregnancy outcomes.

Abstract
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.

Abstract
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.

Abstract
Additional research is needed to establish the safety of biologic agents in pregnancy and lactation. The practitioner should convey information regarding the natural history of rheumatoid arthritis during pregnancy and safety issues related to pharmacotherapies to every woman of childbearing age with RA, well before conception and pregnancy, to ensure optimal outcomes.

Abstract
BACKGROUND Crohn's disease (CD) is associated with increased risk of adverse birth outcomes. However, existing studies have not taken into account the impact of drug treatment. We examined the impact of drug treatment on birth outcomes--low birth weight (LBW), preterm birth, LBW at term, and congenital abnormalities (CAs)--among CD women. METHODS A nationwide Danish cohort study of 900 children born to CD women between 1996 and 2004, based on the National Registry of Patients, the Birth Registry, and the nationwide prescription database. Pregnancies were classified according to receipt of prescriptions for CD medication: no drugs (reference group), 5-aminosalicylic acid (5-ASA)/sulfasalazine, steroids, and azathioprine (AZA)/6-mercaptopurine (6-MP). We used logistic regression analyses to estimate the relative risk of birth outcomes with 95% confidence intervals. We used a proxy measure for disease activity. RESULTS Preterm births were more prevalent among steroid- and AZA/6-MP-exposed women (12.3% and 25%, respectively) compared with the reference group (6.5%). CAs were more prevalent among AZA/6-MP-exposed compared with reference group (15.4%vs 5.7%). Among steroid exposed, the risk of preterm birth was 1.4 (95% CI 0.6-3.3). Among AZA/6-MP exposed, the risk of preterm birth and CAs was 4.2 (95% CI 1.4-12.5) and 2.9 (95% CI 0.9-8.9), respectively. CONCLUSIONS The relative risk of adverse birth outcomes among CD women varied by type of drugs prescribed during pregnancy. The risk of preterm birth and CAs was greater when AZA/6-MP was prescribed, even after adjusting for confounders. However, further information is needed to determine whether the associations are causal.

Abstract
OBJECTIVE To review the toxicity issues of commonly used antirheumatic drugs in pregnancy and lactation. METHODS A review of the medical literature using Medline database via Ovid was performed to identify the toxicities of antirheumatic drugs in pregnancy and lactation. RESULTS Many rheumatologic diseases in women often first present during the childbearing years. In most cases, antirheumatic therapy is required for their disease control. Glucocorticoids may be used during pregnancy; however, first-trimester use should be avoided if possible and breastfeeding should occur 4 hours after the last dosing. Nonsteroidal antiinflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors should be discontinued 6 to 8 weeks before delivery. NSAIDs are compatible with lactation, although there is potential risk of jaundice and kernicterus. There is insufficient data on COX-2 inhibitors and lactation. Hydroxychloroquine and sulfasalazine may be continued throughout pregnancy and lactation. Methotrexate and leflunomide are contraindicated during pregnancy and lactation. Cyclophosphamide and mycophenolate mofetil should be avoided during pregnancy and lactation. Azathioprine and cyclosporine A could be used with caution during pregnancy if felt there is a need to suppress disease activity. They are not compatible with breastfeeding. There are insufficient data regarding tumor necrosis factor-antagonists, anakinra, and rituximab in relation to pregnancy and lactation. Male patients should be made aware of the effects methotrexate, leflunomide, sulfasalazine, and cyclophosphamide may have on their fertility. CONCLUSIONS Health care providers should discuss the risks and benefits of antirheumatic therapy during conception, pregnancy, and lactation with their patients. Better maternal and fetal outcomes can be expected if the pregnancy is planned, the rheumatic disease is stable, and if appropriate medication adjustments can be made ahead of time.

Abstract
OBJECTIVE Limited population-based data on inflammatory bowel disease (IBD) and pregnancy outcomes exist. The purpose of this study is to determine the association between maternal IBD status and adverse pregnancy outcomes. METHODS Using computerized birth records of infants born to mothers with Crohn's disease (CD) or ulcerative colitis (UC) and mothers without diagnoses of IBD (no-IBD) in Washington State, we performed a cross-sectional retrospective study to determine gestational age, birth weight, and congenital malformations. RESULTS Preterm delivery was seen in 15.2% of CD births, 10.4% of UC births, and 7.2% of no-IBD births. Low birth weight was found in 16.8% of CD births, 7.6% of UC births, and 5.3% of no-IBD births. Smallness for gestational age was present in 15.2% of CD births, 10.5% of UC births, and 6.9% of no-IBD births. Only CD births were at significantly increased risk of preterm delivery (p < 0.0025), low birth weight (p < 0.001), and smallness for gestational age (p < 0.001). Congenital malformations were more commonly recorded in UC births than in controls (7.9% vs 1.7%, p < 0.001), whereas 3.4% of CD births had malformations recorded. Using multivariable logistic regression, CD births were more likely to be preterm (odds ratio [OR] = 2.3, 95% CI = 1.4-3.8) and have low birth weights (OR = 3.6, CI = 2.2-5.9) and smallness for gestational age (OR = 2.3, CI = 1.3-3.9). UC births were more likely to have congenital malformations reported (OR = 3.8, CI = 1.5-9.8). CONCLUSIONS Maternal IBD is associated with increased odds of preterm delivery, low birth weight, smallness for gestational age (CD), and reporting of congenital malformations (UC).

Abstract
BACKGROUND We studied the human teratogenic risk of sulfasalazine because this drug interferes with folate metabolism. METHODS Case control study within the Hungarian Case Control Surveillance of Congenital Abnormalities, 1980-1996; based on 22 865 new-born infants or foetuses with congenital abnormalities, and 38 151 babies without any detected congenital abnormalities (control group). RESULTS Seventeen pregnant women (0.07%) were treated with sulfasalazine in the case group, and 26 (0.07%) in the control group. The overall adjusted adds ratio of congenital abnormalities after sulfasalazine treatment was odds ratio = 1.2 (95% confidence interval: 0.6-2.1). None of the analyses indicated any significant increased prevalence of selected congenital abnormalities among the exposed compared with the not exposed. CONCLUSIONS We found no significant increased prevalence of selected congenital abnormalities in the children of women treated with sulfasalazine during pregnancy. However, the amount of information is limited and additional data are needed to rule out a teratogenic effect.

Abstract
The safety of drug therapy for inflammatory bowel disease during pregnancy is an important clinical concern. Current available information is largely derived from animal studies and clinical experience among patients with inflammatory bowel disease and autoimmune disorders and organ transplant recipients. However, these data are confounded by various factors including difficulty projecting the results of animal studies to humans, methodological deficiencies of some studies, insufficient experience with certain agents, difficulty distinguishing the fetal effects of underlying disease from drug therapy and a need to consider the impact of background rates of adverse fetal outcomes which apply to all pregnancies. In inflammatory bowel disease, the effects of active inflammation on the fetus are believed to be more harmful than those of drug treatment, and therapy is often justified to induce or maintain remission during pregnancy. The choice of appropriate treatment is determined by the severity of the disease and the potential for drug toxicity. No causal relationship has been established between exposure to sulfasalazine or other 5-aminosalicylic acid drugs and the development of congenital malformations. These drugs may be used with relative safety during pregnancy and lactation. Considerable experience with corticosteroids have shown them to pose very small risk to the developing fetus. Current evidence indicates that maternal use of azathioprine is not associated with an increased risk of congenital malformations, though impaired fetal immunity, growth retardation or prematurity is occasionally observed. Preliminary evidence derived from patients with inflammatory bowel disease show no significant fetal toxicity following first trimester exposure to mercaptopurine, though its elective use in pregnancy is controversial. Cyclosporin is not teratogenic, but may be associated with growth retardation and prematurity. Pregnancy should be avoided in women treated with methotrexate because of its known abortifacient effects and risk of causing typical malformations. Although treatment with metronidazole or ciprofloxacin for short durations appear to be devoid of adverse fetal reactions, the effect of prolonged exposure as required in Crohn's disease remains unknown.

Abstract
BACKGROUND Little information is available about the safety of high doses of mesalazine during pregnancy. AIM To study the fate of pregnancy and foetal outcome in women taking 1-4 g/day of mesalazine microgranules for inflammatory bowel disease. PATIENTS AND METHODS Case reports were collected from the Pharmacovigilance Department of Ferring SA, France, from a survey conducted in three gastroenterology units, and from a teratology information service. The evolution of pregnancy and foetal outcome were assessed by questionnaire. RESULTS The study covered a total of 123 pregnancies (126 foetuses). Ninety-six women took mesalazine during the first trimester, 85 during the second and 83 during the third. The mean daily dose was 2.1+/-0.8 g; 86 women received <3 g/day (low-dose group), 37 women received > or =3 g/day (high-dose group). The following abnormalities were observed in the low-dose and high-dose groups, respectively: ectopic pregnancy (1/0), spontaneous abortions (1/1), foetal death (0/1), premature deliveries (3/5, P < 0.05), congenital malformations (3/1) and one case of lethal oxalosis. Abnormalities were not considered to be related to mesalazine. CONCLUSIONS The use of oral mesalazine microgranules during pregnancy is safe at doses < or =2 g/day, and probably also at a dose of 3 g/day.

Abstract
The management of inflammatory bowel disease during pregnancy is a particular challenge because adequate disease control before and during gestation is essential for both maternal and foetal health. As a practical problem this situation arises frequently, because a quarter of patients conceive after the diagnosis of their disease. Many of the clinical, biochemical, radiological and endoscopic investigations that are used to monitor and assess disease activity are difficult to use and interpret during pregnancy. Furthermore, patients and clinicians often have concerns about the safety of medical and surgical treatments for the foetus. This review is designed for the practising clinician, to guide the management of patients with inflammatory bowel disease before and during pregnancy. The literature is at times conflicting and data on some issues are scanty, therefore recommendations are based on the balance of evidence including, if necessary, extrapolation from other conditions.

Abstract
Few studies have been performed regarding clinical, radiological and prognostic features of females with spondyloarthropathies other than ankylosing spondylitis (AS). In AS, clinical manifestations appear similar in men and women, whereas radiological features appear more frequent and severe in males. However, no consistent differences in outcome and mortality between men and women have been disclosed. Although fetal outcome is not compromised in women with spondyloarthropathy (SpA), the interaction of pregnancy and SpA has been studied in detail only in AS. Spinal disease is unchanged while peripheral arthritis and uveitis are suppressed during childbearing. Due to possible maternal and fetal side-effects, NSAIDs must be discontinued during the last 8 weeks of pregnancy, but during lactation several NSAIDs can be used. Treatment with sulphasalazine is compatible with pregnancy and lactation. Children of AS patients exhibit a slightly increased risk of developing SpA later in life.

Abstract
BACKGROUND & AIMS Mesalamine is a first-line drug in the treatment of inflammatory bowel disease. Information regarding human pregnancy experience with mesalamine has been scarce and uncontrolled despite its frequent use in women of childbearing age. The aim of this study was to examine the fetal safety of mesalamine. METHODS The Motherisk Program prospectively enrolled and followed up 165 women exposed to mesalamine during pregnancy, 146 of whom had first trimester exposure. Pregnancy outcome was compared with that of a matched control group, who were counseled for nonteratogenic exposure. RESULTS There was no increase in major malformations (1 of 127 [0.8%] for mesalamine vs. 5 of 131 [3.8%] for nonteratogenic controls; P = 0.23). There was an increase in the rate of preterm deliveries (13.0% for mesalamine vs. 4.7% for nonteratogenic controls; P = 0.02), a decrease in the mean maternal weight gain during pregnancy (13.1 +/- 6.3 kg for mesalamine vs. 15.6 +/- 6.0 kg for nonteratogenic controls; P = 0.0002), and a decrease in the mean birth weight (3253 +/- 546 g for mesalamine vs. 3461 +/- 542 g for nonteratogenic controls; P = 0.0005). There were no significant differences in the maternal obstetric history, rates of live births, miscarriages, pregnancy terminations, ectopic pregnancies, delivery method, or fetal distress between the groups. CONCLUSIONS This study suggests that mesalamine does not represent a major teratogenic risk in humans when used in the recommended doses.

Abstract
Four patients with Crohn's disease were treated with an elemental diet during pregnancy. Two had active disease and two also had symptoms of small intestinal obstruction. All went into a clinical remission within a few days of starting treatment. Treatment periods varied from two to four weeks, and were followed by elemental diet as a supplement to normal food in two patients. At term, all delivered a healthy infant. These patients indicate that elemental diet is a safe form of treatment for Crohn's disease during pregnancy and may be considered as an alternative to conventional drug treatments which carry a theoretical risk of teratogenesis.

Abstract
The natural inclination of patients with rheumatic diseases wishing to become pregnant or to breast feed will be to take as few medications as possible. The guidelines outlined above can be used to balance the risk of drug effect on the fetus or neonate with the risk of inducing a flare in disease activity by stopping the drug. Although there are situations where no information on drug behaviour during pregnancy or lactation exists, some guidelines can be developed from a knowledge of the drug's inherent metabolism. In the majority of the rheumatic diseases, disease activity can be reduced to a minimum using the smallest possible dose of drugs known to be safe in pregnancy and lactation, thus providing minimum risk to mother, fetus and neonate.

Abstract
The onset of pregnancy appears to result in the amelioration of rheumatoid disease activity. This is most likely to be related to the change in hormonal, and thus immunological, status of the mother. Spontaneous abortion appears to be increased in mothers with rheumatoid disease. Whether this is due to disease status or to drug therapy is not entirely clear for all cases, but there is a suggestion that it could be the disease state. If at all possible, drugs should be avoided during pregnancy but simple anti-inflammatory drugs in low dosage probably do not produce any major problems. Immunosuppressant drugs should be avoided at all times except when the mother's health is at serious risk. The continued use of disease remitting agents throughout pregnancy is probably not necessary and there is still sufficient question as to whether these drugs could be potentially toxic to the infant.

Abstract
Using the number of calls to the Canadian Motherisk Program as an indicator of the drugs and chemicals frequently of concern to mothers during pregnancy, the risks to the fetus of exposure to these compounds have been reviewed. The drugs which were of concern, and have been proven to be teratogenic, included alcohol, alkylating and antimetabolite agents, stilboestrol, disulfiram, heparin, lithium carbonate, phenytoin, tretinoin (retinoic acid), troxidone and valproic acid. For other compounds studied, there was either no data in the literature or no clear evidence of teratogenicity. The combination of doxylamine and pyridoxine, for example, has been associated with limb reduction defects in isolated case reports: cohort and case-control studies have failed to show a higher-than-baseline risk of malformations. In some cases of exposure to compounds with no known teratogenic potential, other adverse effects to the fetus are possible, and these effects are discussed in detail. In conclusion, when advising a pregnant woman about the potential teratogenic effect of a particular drug or chemical exposure, the health professional should also discuss other factors such as age, obstetric and medical history and the history of other exposures (including alcohol and smoking). In every pregnancy there is a 1 to 5% risk of mayor malformations, and even if the exposure does not appear to increase the teratogenic risk, such a risk still exists.

Abstract
Serum concentrations of sulphasalazine and sulphapyridine were measured during the first week of life in 15 children whose mothers had been on sulphasalazine during pregnancy. The serum concentrations of sulphapyridine and sulphasalazine were similar in the children and their mothers at delivery. The elimination rate of the drugs in the newborn children was slow but the concentrations were not so high that a bilirubin displacing effect could be expected. In eight mothers who were breast-feeding and taking sulphasalazine, analyses were done of mothers' serum, breast-milk and serum from their children. The results showed that the amount of sulphasalazine and sulphapyridine transferred to the child via the breast-milk is negligible with regard to the risk of kernicterus. It is concluded that a woman in need of sulphasalazine treatment can continue the medication throughout pregnancy and lactation without risk of development of kernicterus in her child. Only term infants without haemolytic disease were included in the study. Thus our conclusion is not necessarily valid for the prematurely born child or the child with haemolytic disease.

Abstract
There is accumulating clinical evidence that 5-aminosalicylic acid (5-ASA) represents the therapeutic moiety of sulphasalazine in the treatment of inflammatory bowel disease. For more than 4 decades, the active metabolite, 5-ASA, has been administered in the form of the 'prodrug' sulphasalazine; however, in contrast to sulphasalazine, the pharmacokinetics of 5-ASA were unknown until recently. Sulphasalazine itself is poorly absorbed (3 to 12%) and its elimination half-life of about 5 to 10 hours is probably affected by the absorption process. The major part of sulphasalazine is split by bacterial azo-reduction in the colon into 5-ASA and sulphapyridine, the latter accounting for most of the adverse effects of sulphasalazine. The effective cleavage of sulphasalazine depends on an intact colon and transit time. It is markedly reduced in patients taking antibiotics and after removal of the large bowel. The formed sulphapyridine is almost completely absorbed and eliminated by hydroxylation, glucuronidation and polymorphic acetylation. Depending on the genetic phenotype, the elimination half-life and apparent oral clearance of sulphapyridine are approximately 14 hours and 40 ml/min (slow acetylators) or 6 hours and 150 ml/min (fast acetylators), respectively. Of the 5-ASA released from its 'vehicle' sulphapyridine in the colon, at least 25% is absorbed and after acetylation is subsequently excreted in the urine. At least 50% is eliminated in the faeces. Recently, 5-ASA has also been administered directly in the form of enemas, suppositories and oral slow-release preparations. While the elimination half-life of 5-ASA is short (0.5 to 1.5 h), its major acetylated metabolite (which may be active) exhibits a half-life of 5 to 10 hours. During therapy with sulphasalazine or 5-ASA, steady-state plasma concentrations of 5-ASA are relatively low (less than or equal to 2 micrograms/ml); thus its mode of action appears to be topically rather than systemically. Another approach to deliver the active 5-ASA to the gastrointestinal tract is accomplished with novel 'prodrugs' of 5-ASA, in which the carrier molecule sulphapyridine is replaced by 5-ASA itself (azodisalicylate) or other compounds.

Abstract
Twelve pregnant patients with ulcerative colitis or Crohn's disease who were being treated with sulphasalazine (SASP) were studied together with their newborn, full-term babies. An earlier study had shown almost identical concentrations of SASP and its metabolic sulphapyridine (SP) in maternal and cord serum. As controls, blood samples were collected from 25 healthy women and their newborn infants. Sera from mothers and infants were analysed for the vacant amount of high-affinity bilirubin binding site on albumin (reserve albumin) by the MADDS method. The mean reserve albumin concentration of the SASP-treated mothers was 9% lower than that of the controls, which is probably insignificant. No difference was observed in the corresponding two groups of infants. In vitro studies showed that neither SASP nor SP in therapeutic plasma concentrations had a significant bilirubin-displacing capacity. It seems that SASP preferentially is bound to other sites on albumin than to the high-affinity binding site for bilirubin. The risk of kernicterus in the full-term newborn does not seem to be increased by treatment of the mother with sulphasalazine.
