Inflammatory Bowel Disease in Pregnancy Clinical Care Pathway: A Report From the American Gastroenterological Association IBD Parenthood Project Working Group

Safety of Medications Used to Treat Autoimmune Rheumatic Diseases During Pregnancy and Lactation

ABSTRACT

Autoimmune rheumatic diseases (ARDs) often affect women during their reproductive years, and early studies of pregnancy in these patients reported high rates of adverse outcomes. Continuation or initiation of safe and effective medications in the preconception period is beneficial for maintaining or achieving disease quiescence throughout pregnancy thereby improving both maternal and pregnancy outcomes. The European Alliance of Associations for Rheumatology, the American College of Rheumatology, and the British Society for Rheumatology have published recommendations and guidelines regarding management of ARDs during pregnancy. The American College of Obstetricians and Gynecologists and the American Gastroenterological Association have also provided guidance statements with relevant recommendations. This review provides an overview of available recommendations for medication use in ARD pregnancy, with discussion of safety considerations for maternal and fetal well-being. Medications considered compatible with pregnancy include hydroxychloroquine, sulfasalazine, azathioprine, cyclosporine, tacrolimus, and TNF inhibitors. Methotrexate, mycophenolate, leflunomide, and cyclophosphamide should be avoided before and during pregnancy. Other medications, most of them newer, are largely discouraged for use in pregnancy due to inadequate data or concerns for neonatal immunosuppression, including non-TNF biologics and small molecule therapies. Further investigation is needed regarding effects of non-TNF biologics, biosimilars, and small molecules in pregnancy. Important efforts for the future will include improved methodologies to gather critical safety data, with consideration of inclusion of pregnant women in clinical trials, a complex and controversial issue. Long-term information on outcomes in offspring of treated women is lacking for many of these medications.

Safety and Monitoring of Inflammatory Bowel Disease Advanced Therapies

The recent approval of new medications with novel mechanisms of action and emergence of updated safety information for existing therapies has changed the treatment landscape of inflammatory bowel disease (IBD). These advances led to unique adverse effect profiles and identification of new safety signals, resulting in the evolution of the safety, monitoring, and positioning of IBD therapies. In this updated review, we (1) examine the existing and updated safety data of monoclonal antibodies and small molecules for IBD, with a focus on recently Food and Drug Administration (FDA)-approved therapies, and (2) propose risk stratification and assessment considerations prior to and during IBD treatment.

Validation of the Pharmacokinetic Model for Anti-TNFα Clearance in Infants Exposed to Anti-TNFα During Pregnancy

BACKGROUND AND AIMS

The ECCO guideline recommends postponing live attenuated vaccines in infants exposed to anti-tumour necrosis factor alpha [anti-TNFα] in utero until drug clearance. The aim was to validate the predictive performance of the anti-TNFα clearance model.

METHODS

Newborns and data for anti-TNFα concentrations from the prospective PETIT cohort were included. The anti-TNFα clearance model was used to predict all measured concentrations in the PETIT cohort, based on the measured cord blood concentration and the mean population clearance described in the model. Bayesian maximum a posteriori optimization was used to estimate the use of drug monitoring. Predictive capability and drug monitoring were assessed through mean absolute error [MAE], root mean squared prediction error, and limits of agreement according to Bland and Altman.

RESULTS

Observed drug concentrations after birth were within the 80% prediction interval in 94% of adalimumab samples and 93% of infliximab samples. The anti-TNFα clearance model accurately predicted the concentration at 6 months after birth with an MAE of 0.03 µg/mL [SD 0.03] for adalimumab and 0.11 µg/mL [SD 0.18] for infliximab based on cord blood concentrations. Addition of an additional sample between 1 and 4 months after birth improved the predictive accuracy for infliximab (MAE 0.05 [SD 0.09]) but not for adalimumab. Guidance for use in clinical practice was formulated.

CONCLUSIONS

The validity of the anti-TNFα clearance model is high, and hence can be used to guide clinicians regarding the timing of live vaccines in infants exposed to adalimumab or infliximab in utero.

Ustekinumab in the Treatment of Inflammatory Bowel Diseases: Evolving Paradigms

Inflammatory bowel diseases, comprising Crohn's disease (CD) and ulcerative colitis (UC), are chronic, relapsing, and remitting immune-mediated inflammatory diseases affecting the gastrointestinal tract. Ustekinumab (UST) is a monoclonal antibody that blocks the p40 subunit of the anti-interleukin (IL) 12/23. Pivotal trials (CERTIFI and UNITI-IM for CD, UNIFI for UC) established the efficacy of UST for the induction and maintenance of remission in both CD and UC, with the most favorable results in naïve patients to biologics. In recent years, a wealth of 'real-world' data has emerged supporting positive clinical, endoscopic, and histological outcomes in patients treated with UST, as well as reassuring safety data. More recently, the results of the first head-to-head trials of UST and tumor necrosis factor (TNF) antagonists were reported. Moreover, a number of studies exploring the role of UST in specific clinical settings, such as perianal CD, postoperative complications and recurrence, extraintestinal manifestations, chronic antibiotic-refractory pouchitis, and pregnancy, were reported. This review explores the results reported to date on UST, including those from pivotal trials, real-world data, and emerging studies regarding therapeutic drug monitoring and immunogenicity. The safety profile of UST was also reviewed.

Saudi consensus guidance for the management of inflammatory bowel disease during pregnancy

ABSTRACT

The management of inflammatory bowel disease (IBD) in pregnant women is challenging and must be addressed on a patient-by-patient basis. Optimal patient management requires a multidisciplinary team and clear evidence-based recommendations that cater to this subset of patients. In this article, we provide concise guidelines and clinical care pathway for the management of IBD in pregnant women. Our recommendations were developed by a multidisciplinary working group that includes experts from the Saudi Ministry of Health in collaboration with the Saudi Gastroenterology Association and the Saudi Society of Clinical Pharmacology. All recommendations are based on up-to-date information following an extensive literature review. A total of 23 evidence-based expert opinion recommendations for the management of IBD in pregnant women are herein provided.

Anti-CD20 monoclonal antibody therapy in postpartum women with neurological conditions

OBJECTIVE

Postpartum, patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) have increased risk for disease activity. Anti-CD20 IgG1 monoclonal antibodies (mAb) are increasingly used as disease-modifying therapies (DMTs). Patients may wish to both breastfeed and resume DMT postpartum. This study aimed to determine the transfer of anti-CD20 IgG1 mAbs, ocrelizumab, and rituximab (OCR/RTX), into mature breastmilk and describe maternal and infant outcomes.

METHODS

Fifty-seven cis-women receiving OCR/RTX after 59 pregnancies and their infants were enrolled and followed up to 12M postpartum or 90 days post-infusion. Breastmilk was collected pre-infusion and serially up to 90 days and assayed for mAb concentration. Medical records and patients' questionnaire responses were obtained to assess neurologic, breastfeeding, and infant development outcomes.

RESULTS

The median average concentration of mAb in breastmilk was low (OCR: 0.08 μg/mL, range 0.05-0.4; RTX: 0.03 μg/mL, range 0.005-0.3). Concentration peaked 1-7 days post-infusion in most (77%) and was nearly undetectable after 90 days. Median average relative infant dose was <1% (OCR: 0.1%, range 0.07-0.7; RTX: 0.04%, range 0.005-0.3). Forty-three participants continued to breastfeed post-infusion. At 8-12 months, the proportion of infants' growth between the 3rd and 97th World Health Organization percentiles did not differ for breastfed (36/40) and non-breastfed (14/16, p > 0.05) infants; neither did the proportion with normal development (breastfed: 37/41, non-breastfed: 11/13; p > 0.05). After postpartum infusion, two mothers experienced a clinical relapse.

INTERPRETATION

These confirm minimal transfer of mAb into breastmilk. Anti-CD20 mAb therapy stabilizes MS activity before conception to the postpartum period, and postpartum treatments appears to be safe and well-tolerated for both mother and infant.

Patients Report Infrequent Counseling by Physicians and Inadequate Knowledge about Inflammatory Bowel Disease and Reproductive Health Issues

OBJECTIVE

Inflammatory bowel disease (IBD) reproductive health counseling is associated with higher knowledge, lower voluntary childlessness, greater medication adherence during pregnancy, and improved outcomes of pregnancy. Our aims were to assess counseling and knowledge about IBD and reproductive health in a tertiary care IBD patient population.

STUDY DESIGN

We anonymously surveyed women and men ages 18 to 45 cared for at the Stanford IBD clinic about reproductive health and administered the CCPKnow questionnaire. STATA was used to summarize descriptive statistics and compare categorical variables using Fisher's exact test.

RESULTS

Of the 100 patients (54% women) who completed the survey, only 33% reported prior reproductive health counseling. Both men and women considered not having a child due to IBD (31% women, 15% men) and most (83%) had no prior counseling. A minority of patients had an adequate (≥8/17) CCPKnow score (45% women, 17% men). The majority of women with prior pregnancy had pre-existing IBD (67%), yet many did not seek gastrointestinal (GI) care (38% preconception, 25% during pregnancy) and 33% stopped/changed medications, with 40% not discussing this with a physician. Prior counseling was significantly associated with education level (p = 0.013), biologic use (p = 0.003), and an adequate CCPKnow score (p = 0.01). Overall, 67% of people wanted more information on IBD and reproductive health.

CONCLUSION

In an educated tertiary care cohort, the majority of patients had low CCPKnow scores and rates of IBD reproductive health counseling. Many patients with IBD prior to pregnancy reported no GI care preconception or during pregnancy and stopped/changed medications without consulting a physician. There is an urgent need for proactive counseling by gastroenterologists and obstetricians on IBD and reproductive health.

KEY POINTS

· There is inadequate reproductive health counseling in IBD.. · Many IBD patients do not seek prenatal/perinatal GI care.. · Patients change medications without consultation.. · GIs and OBs should proactively counsel IBD patients..

Pregnancy and medications for inflammatory bowel disease: An updated narrative review

Inflammatory bowel disease (IBD) is often diagnosed during the peak reproductive years of young women. Women with active IBD around conception are at a significantly increased risk of disease relapse during pregnancy, which is associated with poor pregnancy and neonatal outcomes. Given these substantial risks, it is prudent that disease remission should ideally be achieved before conception. Unfortunately, some patients may experience a disease flare-up even if they are in a state of remission before pregnancy. Patients must continue their IBD medications to reduce the risk of disease flare and subsequent poor outcomes during the gestational and postpartum periods. When treating IBD flare-ups during pregnancy, the management is quite similar to the therapeutic approach for non-pregnant patients with IBD, including 5-aminosalicylate, steroids, calcineurin inhibitors (CNIs), and biologic therapies. While the data regarding the safety of CNIs in pregnant women with IBD is limited, the findings in our recent meta-analysis suggest that CNIs may be safer to use in those with IBD than in solid organ transplant recipients. There are several types of biologics and small-molecule therapies currently approved for IBD, and physicians should thoroughly understand their clinical benefits and safety profiles when utilizing these treatments in the context of pregnancy. This review highlights recent studies, including our systematic review and meta-analysis, and discusses the clinical advantages and safety considerations of biologics and small molecules for pregnant women with IBD.

Surgery due to Inflammatory Bowel Disease During Pregnancy: Mothers and Offspring Outcomes From an ECCO Confer Multicentre Case Series [Scar Study]

AIMS

i] To evaluate the evolution of pregnancies and offspring after inflammatory bowel disease [IBD] surgery during pregnancy; and ii] to describe the indications, the surgical techniques, and the frequency of caesarean section concomitant with surgery.

METHODS

Patients operated on due to IBD during pregnancy after 1998 were included. Participating clinicians were asked to review their databases to identify cases. Data on patients' demographics, IBD characteristics, medical treatments, IBD activity, pregnancy outcomes, surgery, delivery, and foetal and maternal outcomes, were recorded.

RESULTS

In all, 44 IBD patients were included, of whom 75% had Crohn's disease; 18% of the surgeries were performed in the first trimester, 55% in the second, and 27% in the third trimester. One patient had complications during surgery, and 27% had postsurgical complications. No patient died. Of deliveries, 70% were carried out by caesarean section. There were 40 newborns alive. There were four miscarriages/stillbirths [one in the first, two in the second, and one in the third trimester]; two occurred during surgery, and another two occurred 2 weeks after surgery; 14% of the surgeries during the second trimester and 64% of those in the third trimester ended up with a simultaneous caesarean section or vaginal delivery. Of the 40 newborns, 61% were premature and 47% had low birth weight; 42% of newborns needed hospitalisation [25% in the intensive care unit].

CONCLUSIONS

IBD surgery during pregnancy remains an extremely serious situation. Therefore, surgical management should be performed in a multidisciplinary team, involving gastroenterologists, colorectal surgeons, obstetricians, and neonatal specialists.

Risk of Postpartum Flare Hospitalizations in Patients with Inflammatory Bowel Disease Persists After Six Months

BACKGROUND

Although patients with IBD are at higher risk for flares during the postpartum period, little is known about the risk factors, timeline, and healthcare-associated costs of a readmission flare.

AIMS

To ascertain the timeline in which patients are hospitalized for postpartum inflammatory bowel disease (IBD) flares, and the associated risk factors.

METHODS

This is a nationwide retrospective cohort study of 7054 patients with IBD who delivered between 2010-2014 obtained from the National Readmissions Database. The presence of IBD was defined using previously validated International Classification of Diseases codes, and univariable and multivariable regression models were performed to assess risk factors associated with a postpartum flare hospitalization over the nine-month observation period.

RESULTS

A total of 353 (5.0%) patients were hospitalized for a postpartum IBD flare, with approximately one-third (30.0%) readmitted after 6 months. On multivariable analysis, having Crohn's disease (aRR 1.47, 95%CI 1.16-1.88), Medicare insurance (aRR 3.30, 95%CI 2.16-5.02), and ≥ 2 comorbidities (aRR 1.34, 95%CI 1.03-1.74) were independently associated with a higher risk of an IBD flare hospitalization. Compared to patients aged 25-29, those 20-24 were at higher risk for an IBD flare readmission (aRR 1.58, 95%CI 1.17-2.13), whereas patients aged 35-39 years were at lower risk (aRR 0.63, 95%CI 0.43-0.92).

CONCLUSIONS

Among patients with IBD, Crohn's disease, Medicare insurance, multiple comorbidities, and younger age were independent risk factors for a postpartum IBD flare hospitalization. As approximately one-third of these readmissions occurred after 6 months, it is imperative to ensure adequate follow-up and treatment for postpartum IBD patients, particularly in the extended postpartum period.

The second decade of anti-TNF-a therapy in clinical practice: new lessons and future directions in the COVID-19 era

Since the late 1990s, tumor necrosis factor alpha (TNF-α) inhibitors (anti-TNFs) have revolutionized the therapy of immune-mediated inflammatory diseases (IMIDs) affecting the gut, joints, skin and eyes. Although the therapeutic armamentarium in IMIDs is being constantly expanded, anti-TNFs remain the cornerstone of their treatment. During the second decade of their application in clinical practice, a large body of additional knowledge has accumulated regarding various aspects of anti-TNF-α therapy, whereas new indications have been added. Recent experimental studies have shown that anti-TNFs exert their beneficial effects not only by restoring aberrant TNF-mediated immune mechanisms, but also by de-activating pathogenic fibroblast-like mesenchymal cells. Real-world data on millions of patients further confirmed the remarkable efficacy of anti-TNFs. It is now clear that anti-TNFs alter the physical course of inflammatory arthritis and inflammatory bowel disease, leading to inhibition of local and systemic bone loss and to a decline in the number of surgeries for disease-related complications, while anti-TNFs improve morbidity and mortality, acting beneficially also on cardiovascular comorbidities. On the other hand, no new safety signals emerged, whereas anti-TNF-α safety in pregnancy and amid the COVID-19 pandemic was confirmed. The use of biosimilars was associated with cost reductions making anti-TNFs more widely available. Moreover, the current implementation of the "treat-to-target" approach and treatment de-escalation strategies of IMIDs were based on anti-TNFs. An intensive search to discover biomarkers to optimize response to anti-TNF-α treatment is currently ongoing. Finally, selective targeting of TNF-α receptors, new forms of anti-TNFs and combinations with other agents, are being tested in clinical trials and will probably expand the spectrum of TNF-α inhibition as a therapeutic strategy for IMIDs.

Maternal Outcomes and Pregnancy-Related Complications Among Hospitalized Women with Inflammatory Bowel Disease: Report from the National Inpatient Sample

BACKGROUND AND AIMS

Previous studies have been inconsistent in reporting the risk of pregnancy-related complications in women with IBD. We aimed to investigate the differences in frequencies of pregnancy-related complications requiring hospitalization in women with IBD compared to women without IBD.

METHODS

We performed a population-based, cross-sectional study using the 2014 USA National Inpatient Sample. Frequencies of ICD-9 codes for pregnancy-related complications in women aged 18-35 years with IBD were compared to women with no IBD controlling for confounders predisposing to pregnancy complications. Adjusted odds ratios were calculated for each outcome.

RESULTS

A total of 6705 women with IBD and a pregnancy complication were discharged from the hospital in 2014. In multivariate analyses, there was no statistically significant difference between women with and without IBD for: spontaneous abortion, post-abortion complications, ectopic pregnancy, hemorrhage, severe preeclampsia, eclampsia, early labor, polyhydramnios, hyperemesis, missed abortion, mental disorder during pregnancy, and forceps delivery. Women with IBD had significant lower odds for prolonged pregnancy, gestational diabetes, fetal distress, umbilical cord complications, obstetric trauma, mild preeclampsia, and hypertension. There was, however, higher odds for infectious and parasitic complications (OR 1.74, 95% CI 1.42-2.14, p < 0.0001), UTIs (OR 1.65, 95% CI 1.07-2.60, p = 0.02), and anemia (OR 5.26, 95% CI 4.01-6.90, p < 0.0001).

CONCLUSIONS

In this large population-based analysis, women with IBD had higher odds for certain infections such as UTIs and anemia during pregnancy when compared to women with no IBD. For other pregnancy-related complications, women with IBD had the same or lower odds than women with no IBD. These data are important to share with women with IBD considering pregnancy.

Methotrexate in inflammatory bowel disease: A primer for gastroenterologists

Methotrexate is an antineoplastic agent that is also used at lower doses for anti-inflammatory properties. Along with thiopurines (azathioprine and 6-mercaptopurine), it has historically been an important part of pharmacological treatment for patients with inflammatory bowel disease. Despite an increase in therapeutic options, these immunomodulators continue to play important roles in the management of inflammatory bowel disease, used either as a monotherapy in mild to moderate cases or in combination with monoclonal antibodies to prevent immunogenicity and maintain efficacy. In light of data linking the use of thiopurines with the risk of malignancies, methotrexate has regained attention as a potential alternative. In this article, we review data on the pharmacology, safety, and efficacy of methotrexate and discuss options for the positioning of methotrexate alone, or in combination, in therapeutic algorithms for Crohn's disease and ulcerative colitis.

Core indicators of an evaluation and guidance system for quality of care in inflammatory bowel disease centers: A critical review

The mission of the IBD Quality Care Evaluation Center (IBDQCC) is to establish indicators of quality of care (QoC), certify IBD units to generate a network of IBD quality care, and eventually improve the national level of IBD healthcare. The final list of 28 core and 13 secondary IBD QoC indicators suitable for the healthcare system in China were selected using a Delphi consensus methodology. Units that met all core indicators were qualified as "regional"; units that met all core indicators together with more than 50% of the secondary indicators received a rating of "excellence." Using the selected QoC core indicators for certifying IBD units, a network of IBD quality care units covering the majority of IBD patients in China was established.

The Patterns of Use of Medications for Inflammatory Bowel Disease During Pregnancy in the US and Sweden Are Changing

BACKGROUND

Population-level data spanning different countries describing oral and parenteral treatment in pregnant women with inflammatory bowel disease (IBD) are scarce. We studied treatment with sulfasalazine/5-aminosalicylates, corticosteroids, thiopurines/immunomodulators, and tumor necrosis factor (TNF)-inhibitors in the United States (Optum Clinformatics Data Mart and the Medicaid Analytics Extract [MAX]) and in the Swedish national health registers.

METHODS

We identified 2975 pregnant women in Optum (2004-2013), 3219 women in MAX (2001-2013), and 1713 women in Sweden (2006-2015) with a recorded diagnosis of IBD. We assessed patterns of use for each drug class according to filled prescriptions, assessing frequency of treatment continuation in those that were treated in the prepregnancy period.

RESULTS

The proportion of women with Crohn's disease and ulcerative colitis on any treatment during pregnancy was 56.1% and 56.3% in Optum, 47.5% and 49.3% in MAX, and 61.3% and 64.7% in Sweden, respectively, and remained stable over time. Sulfasalazine/5-aminosalicylates was the most commonly used treatment in Crohn's disease, ranging from 25.1% in MAX to 31.8% in Optum, and in ulcerative colitis, ranging from 34.9% in MAX to 53.6% in Sweden. From 2006 to 2012, the TNF-inhibitor use increased from 5.0% to 15.5% in Optum, from 3.6% to 8.5% in MAX, and from 0.7% to 8.3% in Sweden. Continuing TNF-inhibitor treatment throughout pregnancy was more common in Optum (55.8%) and in MAX (43.0%) than in Sweden (11.8%).

CONCLUSIONS

In this population-based study from 2 countries, the proportion of women with IBD treatment in pregnancy remained relatively constant. TNF-inhibitor use increased substantially in both countries.

Delivery Outcomes of Pregnant Patients With Inflammatory Bowel Diseases Compared With the General Population and With Women With Other Autoimmune Diseases at a Tertiary Care Center

BACKGROUND

Variable data have suggested that pregnant women with inflammatory bowel diseases (IBD) are more likely to have cesarean deliveries and adverse pregnancy outcomes than the general population. The aim of this study was to describe the rates of cesarean delivery and adverse pregnancy outcomes among patients with IBD as compared with patients with other autoimmune diseases and with the general population.

METHODS

Pregnant patients with IBD, those with non-IBD autoimmune diseases, and control patients were identified. Baseline demographics, disease characteristics, medication use, and delivery outcomes were recorded in a retrospective manner. The primary outcome was overall rate of cesarean delivery; secondary outcomes included rates of planned and unplanned cesarean delivery, delivery complications, preterm delivery, and fetal complications.

RESULTS

Ninety-three women with IBD were age-matched to 376 control patients; 38 women with other autoimmune diseases were also identified. Women with IBD had higher rates of cesarean delivery (47%) when compared with control patients (31%; P < 0.0001) but not when compared with women with other autoimmune diseases. There were high rates of planned cesarean deliveries for IBD-related factors in the IBD cohort. Women with IBD did not have increased rates of adverse delivery or fetal outcomes.

CONCLUSIONS

Women with IBD have higher rates of cesarean delivery than the general population and rates similar to those of women with other autoimmune diseases. Planned cesarean delivery plays an important role in maintaining continuity and sphincter control in select situations, but a diagnosis of IBD does not mandate cesarean delivery.

Shared decision making in pregnancy in inflammatory bowel disease: design of a patient orientated decision aid

Background

Research has indicated a lack of disease-specific reproductive knowledge among patients with Inflammatory Bowel Disease (IBD) and this has been associated with increased “voluntary childlessness”. Furthermore, a lack of knowledge may contribute to inappropriate medication changes during or after pregnancy. Decision aids have been shown to support decision making in pregnancy as well as in multiple other chronic diseases. A published decision aid for pregnancy in IBD has not been identified, despite the benefit of pre-conception counselling and patient desire for a decision support tool. This study aimed to develop and test the feasibility of a decision aid encompassing reproductive decisions in the setting of IBD.

Methods

The International Patient Decision Aid Standards were implemented in the development of the Pregnancy in IBD Decision Aid (PIDA). A multi-disciplinary steering committee was formed. Patient and clinician focus groups were conducted to explore themes of importance in the reproductive decision-making processes in IBD. A PIDA prototype was designed; patient interviews were conducted to obtain further insight into patient perspectives and to test the prototype for feasibility.

Results

Issues considered of importance to patients and clinicians encountering decisions regarding pregnancy in the setting of IBD included fertility, conception timing, inheritance, medications, infant health, impact of surgery, contraception, nutrition and breastfeeding. Emphasis was placed on the provision of preconception counselling early in the disease course. Decisions relating to conception and medications were chosen as the current focus of PIDA, however content inclusion was broad to support use across preconception, pregnancy and post-partum phases. Favourable and constructive user feedback was received.

Conclusions

The novel development of a decision aid for use in pregnancy and IBD was supported by initial user testing.

Pregnancy and neonatal outcomes in women with immune mediated inflammatory diseases exposed to anti-tumor necrosis factor-α during pregnancy: A systemic review and meta-analysis

BACKGROUND

Anti-TNFα is increasingly used as treatment for immune mediated inflammatory diseases (IMID), such as inflammatory bowel disease (IBD), rheumatoid arthritis (RA) and psoriasis (PS). However, the impact of anti-TNFα during pregnancy on mother and newborn is under debate. This requires a sound knowledge of the effects of this treatment on pregnancy and neonatal outcomes.

OBJECTIVES

To assess pregnancy and neonatal outcomes after anti-TNFα therapy during pregnancy in women with IMID, specifically IBD, RA and PS.

METHODS

We performed a systematic review and meta-analysis of 39 studies assessing pregnancy and neonatal outcomes of women with IMID exposed to anti-TNFα agents during pregnancy. We used a random-effects model to determine pooled outcome measures.

RESULTS

An increased risk of preterm births (OR 1.45, 95% CI = 1.16 to 1.82, p = 0.001) and infections in newborns (OR 1.12, 95% CI = 1.00 to 1.27, p = 0.05)) was seen for women in the combined group of IMID exposed to anti-TNFα compared to diseased controls. Specifically for IBD patients exposed to anti-TNFα, the risk was increased for preterm birth (OR 1.66, 95% CI = 1.14 to 2.42, p = 0.009), and low birth weight (OR 1.49, 95% CI = 1.01 to 2.20, p = 0.047) compared to diseased controls. Combined data from studies of women with RA and PS, showed no increased risk for adverse pregnancy outcome after exposure to anti-TNFα. Most children of mothers with IMID received vaccination according to national vaccination schemes and only minor adverse events were reported.

CONCLUSION

Exposure to anti-TNFα agents during pregnancy is associated with increased risk of preterm birth and infections in newborns of women with IMID compared to diseased controls. The risk of preterm birth and low birth weight was increased in women with IBD specifically. The increased risk of infections in newborns underlines the importance of vaccination, which seems to be safe in children exposed to anti-TNFα. Delay of vaccination is therefore unnecessary in these children. These data may aid in balancing the continuing anti-TNFα therapy versus the risk of adverse pregnancy outcomes.

The safety of drugs for inflammatory bowel disease during pregnancy and breastfeeding: the DUMBO registry study protocol of GETECCU

BACKGROUND

Active disease during conception and pregnancy in women with inflammatory bowel disease (IBD) increases the risk of pregnancy complications and adverse neonatal outcomes. The use of IBD treatments during pregnancy should be weighed against their adverse effects on the neonate, but longer-term safety data and data on serious infection rates and malignancies postnatally are lacking, particularly for newer drugs, such as tofacitinib, vedolizumab and ustekinumab.

METHODS

This ongoing, prospective registry study being conducted at 70 centres in Spain is enrolling pregnant women who are ⩾18 years, are at any point in pregnancy up to the end of the second trimester and have a diagnosis of Crohn's disease, ulcerative colitis or unclassified IBD. Patients will receive treatment decided independently by their IBD specialist. Each incident gestation will be followed up through pregnancy and the first 4 years postnatally. Three cohorts will be compared: biologicals exposed, immunomodulatory exposed and non-exposed. The primary endpoint is the risk of severe infection in newborns postnatally up to 4 years of age; other endpoints include serious adverse events (SAEs) such as pregnancy and delivery complications, neonatal SAEs, development [Ages and Stages Questionnaire-3 (ASQ3)], and malignancy incidence, up to 4 years of age. IBD specialists will collect maternal data (baseline/end of each trimester/1 month post-delivery), neonatal birth data, and the SAE and ASQ3 data in children exposed during pregnancy, reported every 3 months by the mother. Statistical analysis will include summary statistics for quantitative variables, comparisons of qualitative variables with significance set at p < 0.025 and a binary logistic regression model to determine the risk factors for severe infections.

RESULTS

Enrolment began in September 2019 and study completion is expected in September 2028.

CONCLUSIONS

This prospective, controlled study will provide evidence on the long-term safety profile in children after intrauterine and lactation exposure to biological and immunomodulatory IBD treatments, including data on postnatal severe infections, development and malignancies.

Biologics and pregnancy: a clinician's guide to the management of IBD in pregnant women

Introduction: Women with inflammatory bowel disease (IBD) endorse a tremendous amount of concern about medication exposure during pregnancy and their effects on the fetus. Medical providers caring for this patient population should be well informed and feel comfortable counseling their patients for the best pregnancy outcome possible.Areas covered: It is of particular importance to understand the implications of use of biologics in preconception, pregnancy, and postpartum timeframes. Herein, we aim to inform the clinician about the impact of uncontrolled inflammation during pregnancy, the mechanisms of biologic transport through the placenta, the effects of biologics in maternal and neonatal outcomes, and additional postpartum considerations such as breastfeeding and vaccination safety.Expert opinion: The groundwork already set by previous research in terms of safety of biologic therapy during pregnancy has been reassuring. With the advent of more mechanisms of action but similar protein structure, i.e. they are IgG1 antibodies; the authors anticipate the recommendation of continuation of therapy throughout pregnancy will be sustained.

Safety of New Biologics (Vedolizumab and Ustekinumab) and Small Molecules (Tofacitinib) During Pregnancy: A Review

Two new biological drugs (vedolizumab and ustekinumab) and one small molecule (tofacitinib) have been recently approved for the treatment of inflammatory bowel disease. Therefore, we must be familiar with the safety of these "new" drugs during pregnancy and breastfeeding. In the present article, we critically review available data on the safety of new biologics (vedolizumab and ustekinumab) and small molecules (tofacitinib) during pregnancy and breastfeeding, with special focus on women with inflammatory bowel disease. Bibliographical searches (MEDLINE) up to April 2020 were performed. The timing and mechanisms of placental transfer of vedolizumab and ustekinumab are expected to be similar to anti-TNF agents. Animal studies show no evidence of adverse effects on pre- or post-natal development after administration of vedolizumab and ustekinumab. Just a few studies including patients treated with vedolizumab or ustekinumab during pregnancy have been published, reporting uneventful pregnancies in most cases. The clinical programme of both drugs and post-marketing studies showed no new safety concerns. Due to the expected safety of vedolizumab and ustekinumab during pregnancy, it may be recommended to plan the final pregnancy dose approximately 8 or 12 weeks, respectively, before the estimated date of delivery. Live vaccines should be avoided for up to a year in children exposed in utero to vedolizumab or ustekinumab unless drug elimination has been documented. Miniscule amounts of vedolizumab and ustekinumab are transferred to breast milk, so breastfeeding is probably safe. There is no evidence of adverse effect of vedolizumab or ustekinumab paternal exposure. Regarding tofacitinib, it is reasonable to assume that this molecule crosses the placenta from the beginning of pregnancy. In animal studies, tofacitinib was feticidal and teratogenic in rats and rabbits, although at exposures many times greater than the standard human dose. Reported outcomes of pregnancy cases identified from tofacitinib randomised controlled trials, post-approval and non-interventional studies, and spontaneous adverse-event reporting appear similar to those observed in the general population. Nevertheless, at present, the use of tofacitinib during pregnancy should be avoided. Although no human studies have reported outcomes of breastfeeding with small molecules such as tofacitinib, this drug is present in lactating rat milk so, at present, breastfeeding should be avoided. Pregnancy among patients with paternal exposure to tofacitinib appears to be safe. In summary, we can conclude that new biologic agents (vedolizumab and ustekinumab) and small molecules (tofacitinib) should be used during pregnancy only if the benefits to the mother outweigh the risks to the mother and unborn child.

Inflammatory Bowel Disease Nurse-Practical Messages

Background and Objectives: Patients affected by inflammatory bowel diseases (IBDs) are complex patients with various problems from a clinical and psychological point of view. This complexity must be addressed by a multidisciplinary team, and an inflammatory bowel disease nurse can be the ideal professional figure to create a link between doctor and patient. The objective of this comprehensive review is to describe the figure of inflammatory bowel disease nurses and the various benefits that their introduction into a multidisciplinary team can bring, as well as a focus on how to become an inflammatory bowel disease nurse. Materials and Methods: A search on the PubMed database was performed by associating the terms "IBD" or "inflammatory bowel disease" with the Boolean term AND to the various issues addressed: "life impact", "communication", "fistulas", "ostomy", "diet", "incontinence", "sexuality", "parenthood", "fatigue", "pain management", and "follow up appointments". Regarding the analysis of the benefits that the IBD nurse brings, the terms "IBD", "inflammatory bowel diseases", "Crohn's disease", and "ulcerative colitis" were used, associating them with the terms "benefit", "costs", "team", and "patients". Finally, regarding the focus on how to become an IBD nurse, an IBD nurse was interviewed. Results: An IBD nurse is a valuable nursing figure within the multidisciplinary team that takes care of patients with IBD because this nurse performs important functions from both a clinical assistance point of view (management of fistulas, ostomies, infusion of biological drugs) and an information and therapeutic education point of view (communication with patients, direct contact with patients by telephone or email). Furthermore, this nurse performs the "filter" function between doctor and patient, saving time for doctors that will be used for more outpatient visits. Conclusions: The introduction of an inflammatory bowel disease nurse is therefore recommended for multidisciplinary organizations dealing with the clinical course of patients suffering from IBD.

Factors Associated with Inflammatory Bowel Disease Flare During Pregnancy Among Women with Preconception Remission

BACKGROUND

The factors associated with inflammatory bowel diseases (IBD) relapse throughout gestation in those with preconception remission remain unknown.

AIMS

We aimed to investigate disease and pregnancy course among IBD women with quiescent disease at conception.

METHODS

Women with IBD attending a multidisciplinary clinic for preconception, antenatal and postnatal treatment were prospectively recruited during 2011-2018.

RESULTS

Overall, 298 women with IBD with quiescent disease at the time of conception constituted the study cohort. Of these, 112 (37.6%) women experienced disease flare during pregnancy. The risk of disease relapse was higher in those with ulcerative colitis (UC) as compared to those with Crohn's disease (CD) (48.1% vs. 31.8%, P = 0.005). The proportion of women with prior IBD-related gastrointestinal surgery was lower in those who experienced disease flare up (13.4% vs. 26.3%, P = 0.009). The use of biologic therapy at the time of conception was associated with lower rates of disease relapse (25.0% vs. 43.9%, P = 0.001). In multivariate analysis, use of conventional medications or no treatment (aOR [95% CI]: 2.0 (1.12, 3.57), P = 0.02) and lack of prior history of IBD-related surgery (aOR [95% CI]: 3.13 (1.37, 7.14), P = 0.007) were independently positively associated with disease relapse. Rates of hospitalization during pregnancy (21.4% vs. 2.2%, P < 0.001) and preterm delivery (22.3% vs. 9.1%, P = 0.002) were higher, and birthweight was lower (median 2987 vs. 3153 grams, P = 0.05) in those with disease flare as compared to those who maintained remission.

CONCLUSION

Prior IBD-related surgery and biologic therapy were found as independent protective factors against relapse during pregnancy among women with quiescent disease at conception.

Women's Health and Ulcerative Colitis

Although ulcerative colitis affects males and females at similar rates, certain sex-specific differences influence the disease-related risks and experiences of females with ulcerative colitis. This article reviews topics that affect females with ulcerative colitis, including the impact of disease on the menstrual cycle, fertility, child bearing, sexual health, and recommendations for health care maintenance.

Implications of COVID-19 for inflammatory bowel disease: Opportunities and challenges amidst the pandemic

Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic various measures have been taken to mitigate the effects of the global health crisis in this unprecedented time. According to the World Health Organization, more than 5 million people have been infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and with more than 300000 deaths attributed to COVID-19 worldwide. There is emerging evidence that SARS-CoV-2 utilizes angiotensin-converting enzyme 2 receptors to enter human cells which are found in abundance in the alveoli and intestines. In addition, the infection is noted to be more severe in patients with co-morbid conditions, those who are malnourished, immunosuppressed and immunocompromised. Inflammatory bowel disease (IBD) which includes ulcerative colitis and Crohn’s disease is chronic remitting and relapsing disorders with intestinal and extraintestinal manifestation. IBD patients are often malnourished and on immunosuppressive medications and there is a hypothetical concern that IBD patients are at substantial risk of COVID-19 infection. The management of IBD patients is often complex and poses unique challenges for gastroenterologists during the pandemic. The purpose of this review article is to summarize the growing level of evidence and understanding of the management of IBD during the COVID-19 pandemic, in the light of international and national gastroenterology society guidelines. We performed a thorough literature search on IBD, SARS-CoV-2 and COVID-19 on PubMed, EMBASE, OVID Medline and Google Scholar and pertaining literature was critically examined and summarized. Per national and international society guidelines and recommendations, IBD is not a risk factor for SARS-CoV-2 infection. IBD patients should continue with their medications and they should follow universal precautions i.e. masks, hand and respiratory hygiene and avoidance of health care facilities and public toilets as general population. Among IBD patients older age, having active disease, and co-morbid conditions are risk factors for a severe SARS-CoV-2 infection. Furthermore, elective endoscopic and surgical procedures can be delayed or deferred until discussing the risks and benefits with patients.

Clinical utility of fecal calprotectin in monitoring disease activity and predicting relapse in pregnant patients with inflammatory bowel diseases

OBJECTIVES

Inflammatory bowel diseases (IBDs) are commonly diagnosed in reproductive-aged women and can substantially affect pregnancy outcomes. Non-invasive monitoring of IBD during the prenatal course is particularly challenging as traditional laboratory biomarkers are often affected by pregnancy-related physiologic changes. We aimed to evaluate the role of fecal calprotectin (FC) in monitoring disease activity and predicting relapse among IBD women throughout gestation.

METHODS

Women with IBD attending a multidisciplinary clinic for the preconception, antenatal and postnatal treatment were prospectively recruited during 2014-2018. FC levels were determined with an enzyme-linked immunoassay.

RESULTS

A total of 265 FC (preconception, n = 41; 1st trimester, n = 48; 2nd trimester, n = 84; 3rd trimester, n = 76; postpartum, n = 16) measurements were obtained in 157 pregnancies. Higher FC concentrations were found in all time points in those with active disease than those in remission as assessed by either physician global assessment or disease clinical scores. FC levels were significantly correlated with physician global assessment and disease activity indices in all 5 periods of investigation. Excluding those with disease flare at the time of conception, disease relapse was encountered during the prenatal course in 40 (31.5%) of the remaining 127 pregnancies. FC levels were significantly higher in those who experienced a disease flare later in the course of gestation as compared to those who maintained clinical remission (median 341 vs. 224 μg/g, P = 0.04).

CONCLUSION

FC appears to be a reliable marker of ongoing disease activity throughout the prenatal course as well as a predictor of imminent disease flare among IBD pregnant patients.

Relationship between nutrition and reproduction

BACKGROUND

Recently, the relationship between nutrition and reproduction is being studied. In particular, when older women receive reproductive treatment, egg aging causes greater problems than organic factors.

METHODS

This study investigated the relationship between nutrition and reproduction with a focus on factors that cause aging, including oxidation, glycation, and chronic inflammation. A large volume of data concerning each nutrient's relationship with reproductive medicine was collected from a number of observational studies.

MAIN FINDINGS

The results showed that refined carbohydrates should be avoided and care should be taken to achieve proper intake of omega-3 fatty acids. Folic acid and vitamin D were also effective. For men, antioxidant measures are especially effective. The effects of antioxidants are related to insulin resistance, which causes chronic inflammation.

CONCLUSION

Recent research has shown that rather than meal content, meal intervals are more important for improving insulin resistance. Future research should examine lifestyle-related nutrition factors and their relationships to reproductive treatment.

Transfer of monoclonal antibodies into breastmilk in neurologic and non-neurologic diseases

OBJECTIVE

To review currently available data on the transfer of monoclonal antibodies (mAbs) in the breastmilk of women receiving treatment for neurologic and non-neurologic diseases.

METHODS

We systematically searched the medical literature for studies referring to 19 selected mAb therapies frequently used in neurologic conditions and "breastmilk," "breast milk," "breastfeeding," or "lactation." From an initial list of 288 unique references, 29 distinct full-text studies met the eligibility criteria. One additional study was added after the literature search based on expert knowledge of an additional article. These 30 studies were reviewed. These assessed the presence of our selected mAbs in human breastmilk in samples collected from a total of 155 individual women.

RESULTS

Drug concentrations were typically low in breastmilk and tended to peak within 48 hours, although maximum levels could occur up to 14 days from infusion. Most studies did not evaluate the breastmilk to maternal serum drug concentration ratio, but in those evaluating this, the highest ratio was 1:20 for infliximab. Relative infant dose, a metric comparing the infant with maternal drug dose (<10% is generally considered safe), was evaluated for certolizumab (<1%), rituximab (<1%), and natalizumab (maximum of 5.3%; cumulative effects of monthly dosing are anticipated). Importantly, a total of 368 infants were followed for ≥6 months after exposure to breastmilk of mothers treated with mAbs; none experienced reported developmental delay or serious infections.

CONCLUSIONS

The current data are reassuring for low mAb drug transfer to breastmilk, but further studies are needed, including of longer-term effects on infant immunity and childhood development.

Management of Plaque Psoriasis With Biologic Therapies in Women of Child-Bearing Potential Consensus Paper

BACKGROUND

Plaque psoriasis (PsO) is a chronic inflammatory disease that often presents at peak reproductive age in women of child-bearing potential (WOCBP). With the emergence of biologic therapies to treat PsO, guidance on disease management in WOCBP is needed to inform treatment decisions before, during, and after pregnancy.

OBJECTIVES

To develop a practical, up-to-date consensus document, based on available evidence and expert opinion where evidence was lacking, in order to guide both Canadian and international clinicians treating PsO in WOCBP.

METHODS

A panel of 9 Canadian dermatologists with extensive clinical experience managing PsO reviewed the relevant literature from the past 25 years in 3 key domains: overview of PsO in WOCBP and clinical considerations, treatment considerations, and postpartum considerations. The structured literature search focused on WOCBP treated with TNF-alpha inhibitors (adalimumab, certolizumab, etanercept, golimumab, infliximab), IL-23 inhibitors (guselkumab, risankizumab, tildrakizumab), IL-12/23 inhibitors (ustekinumab), and IL-17 inhibitors (brodalumab, ixekizumab, secukinumab). This literature review, along with clinical expertise and opinion, was used to develop concise and clinically relevant consensus statements to guide practical management of PsO in WOCBP. Experts voted on the statements using a modified Delphi process and prespecified agreement cut-off of 75%.

RESULTS AND IMPLICATIONS

After review, discussion, and voting on 19 draft consensus statements at an in-person meeting and remotely, 12 consensus statements were approved by the expert panel. The statements presented here will guide healthcare providers in practical disease management using biologic therapies for the treatment of PsO in WOCBP.

Disease flare at prior pregnancy and disease activity at conception are important determinants of disease relapse at subsequent pregnancy in women with inflammatory bowel diseases

PURPOSE

Disease flare throughout gestation are not uncommon among women with inflammatory bowel diseases (IBD), and can substantially affect pregnancy outcomes. We aimed to evaluate the effect of prior pregnancy outcome on the risk of disease flare at subsequent pregnancy in women with IBD.

METHODS

Women with IBD attending a multidisciplinary clinic for the preconception, antenatal and postnatal treatment were prospectively recruited during 2011-2018.

RESULTS

Overall, 476 IBD women were followed during the study period. Of them, 69 (14.5%) had two pregnancies throughout follow-up period and constituted the study cohort. Among these 69 women, 48 (69.6%) had Crohn's disease and 21 (30.4%) ulcerative colitis. The median interpregnancy interval was 20 [11-32] months. Overall, 34 (49.3%) women experienced disease flare at the subsequent pregnancy. In multivariate analysis, active disease at conception (odds ratio [95% CI]: 25.65 (3.05, 25.52), P < 0.001) and history of disease flare at the previous pregnancy (odds ratio [95% CI]: 4.21 (1.10, 16.58), P < 0.001) were the only independent predictors of disease relapse in current gestation. Rates of hospitalization during pregnancy (14.7% vs. 0, P = 0.02) and preterm delivery (32.4% vs. 5.7%, P = 0.006) were higher, and neonatal birth weight was lower (median 3039 vs. 3300 g, P = 0.03), in those with disease flare as compared to those with maintained remission.

CONCLUSION

History of disease relapse at previous gestation and periconception disease activity were found as important predictors of disease flare among IBD women. These data would facilitate adequate counseling and informed management decisions among reproductive-aged IBD women and their treating physicians.

Navigating monoclonal antibody use in breastfeeding women: Do no harm or do little good?

Many neurologic diseases disproportionately affect women, particularly during their reproductive years. For many of these diseases, monoclonal antibodies (mAbs) are becoming widely available as a treatment option, for example, in migraine, multiple sclerosis, and myasthenia gravis. Yet, despite how common pregnancy is (latest estimates suggest that 86% of US women ages 40-44 have given birth), there is a paucity of research on the safety of prescription medications, including mAbs, during the peripartum period. In this article, we focus on the safety of mAbs during breastfeeding. We summarize how pregnancy affects the trajectory of these diseases and explore the benefit derived from mAb therapies. We posit that as neurologists, we are uniquely poised to lead the study of peripartum safety for the mAbs now on the market and provide a framework for their future study.
