Infertile patients with inflammatory bowel disease have comparable in vitro fertilization clinical outcomes to the general infertile population

[Position statement of the Spanish Society of Primary Care Physicians (SEMERGEN) and Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) on the management of inflammatory bowel disease in Primary Care]

Primary Care is the first point of contact for most patients after the onset of symptoms of inflammatory bowel disease (IBD). Establishing an initial diagnostic process based on compatible symptoms and agreed criteria and referral pathways, depending on the degree of suspicion and the patient's situation, can reduce diagnostic delays. Once the patient is referred to the Digestive specialist and the diagnosis of IBD is established, a treatment and follow-up plan is structured. The management of the patient must be shared with the participation of the family practitioners in the diagnosis and treatment of concomitant or intercurrent pathologies, the recognition of flare-ups or complications (of IBD or treatments), education tasks or adherence control. With the purpose of developing a comprehensive guide on the management of IBD aimed at Primary Care doctors, we have developed this positioning document collaboratively between the Spanish Society of Primary Care Physicians (SEMERGEN) and the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU).

Reasons for reduced reproduction after colectomy in women with ulcerative colitis

OBJECTIVES

Colectomy and subsequent bowel reconstruction in women with ulcerative colitis (UC) is associated with decreased fertility, this survey aims to investigate possible reasons for this.

MATERIAL AND METHODS

Women with UC aged 18-44 years at colectomy 2000-2020 were identified and data were retrieved from the Swedish inflammatory bowel disease register (SWIBREG). Additional information was obtained using a study-specific questionnaire.

RESULTS

The survey was completed by 214 (72.8%) out of 294 eligible women. Mean age at disease onset was 22.9 years (standard deviation 0.5). No reconstruction was made in 67 (31.3%) women, whereof 24 (35.8%) had a completion proctectomy. Reconstruction was performed with ileorectal anastomosis (IRA) in 66 (30.8%) women and ileal pouch anal anastomosis (IPAA) in 81 (37.9%). Included women had on average 1.67 children (95% confidence interval 1.53-1.81) at the end of follow-up. The desire to have children was negatively affected by disease onset (59.4%), colectomy (44.9%) and reconstruction (36.7%). Altogether, 39.4% estimated that they had fewer children and 9.5% restrained completely from having children because of the disease. Difficulties to conceive were reported by 36.5% including 18.9% who expressed that they could not conceive at all. Difficulties to conceive was more common after reconstruction with IPAA (Odds Ratio [OR] 5.54) than IRA (OR 2.57).

CONCLUSIONS

A majority of women with UC and colectomy expressed that the disease affected their desire to have children, more often limiting the number of children than completely refraining. For childless patients, difficulties to conceive was more common than voluntary childlessness.

Navigating Reproductive Care in Patients With Inflammatory Bowel Disease: A Comprehensive Review

Inflammatory bowel disease [IBD] is often diagnosed in patients during their reproductive years. It is crucial that both healthcare providers and patients are adequately informed to avoid misguided decisions regarding family planning. One of the most important aspects during conception and pregnancy is to maintain disease remission, as disease activity is associated with adverse pregnancy outcomes. Apart from methotrexate, most conventional drugs used in IBD are considered low risk during conception and pregnancy. For newer agents, evidence is still limited. If needed, surgery must not be postponed and should ideally be performed in specialized centres. In most patients, delivery should be vaginal except for patients with complex perianal disease, with an ileoanal pouch anastomosis, or if there is an obstetric contraindication. In children exposed to biological treatments during pregnancy, the risk of infections appears to be low, and psychomotor development is probably not affected. Regarding immunizations, the standard vaccination schedule for inactivated vaccines should be followed for children exposed to biologics in utero. In the case of live vaccines, such as rotavirus, decisions should be individualized and take into consideration the risk-benefit ratio, particularly in developing countries. In this review, we provide a comprehensive and updated overview of aspects related to fertility, pregnancy, breastfeeding, and the impact on the care of children born to mothers with IBD. Both the available evidence and areas of uncertainty are discussed, with the goal of assisting healthcare professionals caring for IBD patients during this important stage of their lives.

Factors associated with decreased ovarian reserve in Crohn's disease: A systematic review and meta-analysis

INTRODUCTION

It is still unclear whether Crohn's disease (CD) might be associated with diminished ovarian reserve (OvR) and factors influencing anti-Mullerian hormone (AMH) levels in CD are poorly known.

MATERIAL AND METHODS

We conducted a comprehensive literature search of multiple electronic databases from inception to June 2022 to identify all studies reporting AMH levels or factors associated with diminished OvR in patients with CD.

RESULTS

Of the 48 studies identified in our search, eight (including 418 patients with CD) were finally included. The mean difference (95% confidence interval [CI]) in the AMH level between pooled CD patients and controls was -0.56 (-1.14 to 0.03) (p = 0.06). A history of CD-related surgery was not associated with a lower OvR (odds ratio, OR [95% CI] 1.34, [0.66-2.7]; p = 0.4). While disease activity and perianal disease seems associated with a low OvR, disease location (L2 vs. L1, OR [95% CI] = 95% CI [0.47-7.4]; p = 0.4) and L3 vs. L1 (OR [95% CI] = 1.44 [0.67-3.12]; p = 0.3), CD medication, and disease behavior were not.

CONCLUSIONS

Our systematic review and meta-analysis did not identify a significantly low OvR in patients with CD. Contrary to CD-related surgery risk factor, active disease was associated lower AMH levels.

Inflammatory Bowel Disease and Reproductive Health: A Focus on Pregnancy Planning and Outcomes

Reproductive counseling is crucial for women's health, especially for those with inflammatory bowel disease (IBD), which often affects younger patients during their childbearing years. Patients with IBD need special considerations when planning for pregnancy. Preconception counseling is important as it helps patients make informed decisions about pregnancy and allows for optimal management of IBD before, during, and after pregnancy. In this review, we aim to provide guidance for managing and treating patients with IBD throughout the preconception, pregnancy, and postpartum period.

Updates on the management of inflammatory bowel disease from periconception to pregnancy and lactation

Inflammatory bowel disease (IBD) affects reproductive planning due to psychological effects and mechanical problems related to surgery. Children of people with IBD have an increased risk of about 10% if one parent has IBD and up to 33% if both parents have IBD. The fertility of people with IBD is similar to the general population, but fertility might be reduced in individuals with active IBD, ileal pouch-anal anastomosis, or perianal Crohn's disease. Flaring disease during pregnancy increases complications, such as preterm birth. Thus, disease management with appropriate medications can optimise outcomes. As most medications have minimal fetal risks, people with IBD should be informed about the risks of stopping medications and the importance of maintaining remission. A period of disease remission is advisable before pregnancy and could reduce the risks for both the pregnant person and the fetus. Flexible endoscopy, intestinal ultrasound, and gadolinium-free magnetic resonance enterography are safe during pregnancy. We provide state-of-the-art knowledge on the basis of the latest evidence to ensure successful pregnancy outcomes in controlled IBD.

Opening the black box: why do euploid blastocysts fail to implant? A systematic review and meta-analysis

BACKGROUND

A normal chromosomal constitution defined through PGT-A assessing all chromosomes on trophectoderm (TE) biopsies represents the strongest predictor of embryo implantation. Yet, its positive predictive value is not higher than 50-60%. This gap of knowledge on the causes of euploid blastocysts' reproductive failure is known as 'the black box of implantation'.

OBJECTIVE AND RATIONALE

Several embryonic, maternal, paternal, clinical, and IVF laboratory features were scrutinized for their putative association with reproductive success or implantation failure of euploid blastocysts.

SEARCH METHODS

A systematic bibliographical search was conducted without temporal limits up to August 2021. The keywords were '(blastocyst OR day5 embryo OR day6 embryo OR day7 embryo) AND (euploid OR chromosomally normal OR preimplantation genetic testing) AND (implantation OR implantation failure OR miscarriage OR abortion OR live birth OR biochemical pregnancy OR recurrent implantation failure)'. Overall, 1608 items were identified and screened. We included all prospective or retrospective clinical studies and randomized-controlled-trials (RCTs) that assessed any feature associated with live-birth rates (LBR) and/or miscarriage rates (MR) among non-mosaic euploid blastocyst transfer after TE biopsy and PGT-A. In total, 41 reviews and 372 papers were selected, clustered according to a common focus, and thoroughly reviewed. The PRISMA guideline was followed, the PICO model was adopted, and ROBINS-I and ROB 2.0 scoring were used to assess putative bias. Bias across studies regarding the LBR was also assessed using visual inspection of funnel plots and the trim and fill method. Categorical data were combined with a pooled-OR. The random-effect model was used to conduct the meta-analysis. Between-study heterogeneity was addressed using I2. Whenever not suitable for the meta-analysis, the included studies were simply described for their results. The study protocol was registered at http://www.crd.york.ac.uk/PROSPERO/ (registration number CRD42021275329).

OUTCOMES

We included 372 original papers (335 retrospective studies, 30 prospective studies and 7 RCTs) and 41 reviews. However, most of the studies were retrospective, or characterized by small sample sizes, thus prone to bias, which reduces the quality of the evidence to low or very low. Reduced inner cell mass (7 studies, OR: 0.37, 95% CI: 0.27-0.52, I2 = 53%), or TE quality (9 studies, OR: 0.53, 95% CI: 0.43-0.67, I2 = 70%), overall blastocyst quality worse than Gardner's BB-grade (8 studies, OR: 0.40, 95% CI: 0.24-0.67, I2 = 83%), developmental delay (18 studies, OR: 0.56, 95% CI: 0.49-0.63, I2 = 47%), and (by qualitative analysis) some morphodynamic abnormalities pinpointed through time-lapse microscopy (abnormal cleavage patterns, spontaneous blastocyst collapse, longer time of morula formation I, time of blastulation (tB), and duration of blastulation) were all associated with poorer reproductive outcomes. Slightly lower LBR, even in the context of PGT-A, was reported among women ≥38 years (7 studies, OR: 0.87, 95% CI: 0.75-1.00, I2 = 31%), while obesity was associated with both lower LBR (2 studies, OR: 0.66, 95% CI: 0.55-0.79, I2 = 0%) and higher MR (2 studies, OR: 1.8, 95% CI: 1.08-2.99, I2 = 52%). The experience of previous repeated implantation failures (RIF) was also associated with lower LBR (3 studies, OR: 0.72, 95% CI: 0.55-0.93, I2 = 0%). By qualitative analysis, among hormonal assessments, only abnormal progesterone levels prior to transfer were associated with LBR and MR after PGT-A. Among the clinical protocols used, vitrified-warmed embryo transfer was more effective than fresh transfer (2 studies, OR: 1.56, 95% CI: 1.05-2.33, I2 = 23%) after PGT-A. Lastly, multiple vitrification-warming cycles (2 studies, OR: 0.41, 95% CI: 0.22-0.77, I2 = 50%) or (by qualitative analysis) a high number of cells biopsied may slightly reduce the LBR, while simultaneous zona-pellucida opening and TE biopsy allowed better results than the Day 3 hatching-based protocol (3 studies, OR: 1.41, 95% CI: 1.18-1.69, I2 = 0%).

WIDER IMPLICATIONS

Embryo selection aims at shortening the time-to-pregnancy, while minimizing the reproductive risks. Knowing which features are associated with the reproductive competence of euploid blastocysts is therefore critical to define, implement, and validate safer and more efficient clinical workflows. Future research should be directed towards: (i) systematic investigations of the mechanisms involved in reproductive aging beyond de novo chromosomal abnormalities, and how lifestyle and nutrition may accelerate or exacerbate their consequences; (ii) improved evaluation of the uterine and blastocyst-endometrial dialogue, both of which represent black boxes themselves; (iii) standardization/automation of embryo assessment and IVF protocols; (iv) additional invasive or preferably non-invasive tools for embryo selection. Only by filling these gaps we may finally crack the riddle behind 'the black box of implantation'.

Clinical advances: pregnancy in gastroenterologic and hepatic conditions

The fields of gastroenterology and hepatology, along with endoscopic practice, have seen significant changes and innovations to practice in just the past few years. These practice changes are not limited to gastroenterology, but maternal fetal medicine and the care of the pregnant person have become increasingly more sophisticated as well. Gastroenterologists are frequently called on to provide consultative input and/or perform endoscopy during pregnancy. To be able to provide the best possible care to these patients, gastroenterologists need to be aware of (and familiar with) the various nuances and caveats related to the care of pregnant patients who either have underlying gastrointestinal (GI) conditions or present with GI and liver disorders. Here, we offer a clinical update with references more recent than 2018, along with a few words about SARS-CoV-2 infection and its relevance to pregnancy.

Inflammatory bowel disease in pregnancy and breastfeeding

Inflammatory bowel disease (IBD) has a peak age of diagnosis before the age of 35 years. Concerns about infertility, adverse pregnancy outcomes, and heritability of IBD have influenced decision-making for patients of childbearing age and their care providers. The interplay between the complex physiology in pregnancy and IBD can affect placental development, microbiome composition and responses to therapy. Current evidence has shown that effective disease management, including pre-conception counselling, multidisciplinary care and therapeutic agents to minimize disease activity, can improve pregnancy outcomes. This Review outlines the management of IBD in pregnancy and the safety of IBD therapies, including novel agents, with regard to both maternal and fetal health. The vast majority of IBD therapies can be used with low risk during pregnancy and lactation without substantial effects on neonatal outcomes.

Obstetric Considerations in Pregnant Women with Crohn's Disease

Crohn's disease affects many women of childbearing age. Fecundity rates are often lower than in the general population due to reduced fertility during active inflammation, effects of pelvic surgery or voluntary childlessness. Many women have concerns regarding the effects of pregnancy on their Crohn's, any potential effect of medication on the fetus, and passing on Crohn's disease to the offspring. International guidelines on reproduction for women with Crohn's disease provide evidence-based advice to patients and health care professionals. There is an increasing literature on the safety of advanced medication for Crohn's disease during pregnancy. This review article therefore focuses on obstetric considerations beyond medication safety. We provide information on fertility, factors affecting pregnancy and fetal outcomes, obstetric complications, factors influencing mode of delivery, management of intestinal stomas during pregnancy and general considerations around breast feeding.

A Practical Approach to IBD Care in the Pregnant Patient

PURPOSE OF REVIEW

As the incidence of inflammatory bowel disease (IBD) rises, gastroenterologists are more commonly facing management of the disease in women of childbearing age. This coincides with the development of new IBD therapies whose use in pregnancy must be considered.

RECENT FINDINGS

This review provides updated recommendations for newer biologic agents and small molecules that have been approved for IBD treatment since the previous guidelines were published. In addition, recent research has found that prior IBD-related surgeries, not just ileal pouch-anal anastomosis, can impact pregnancy outcomes. Reassuringly, assisted reproductive technology for IBD patients has been found to have similar success rates to the non-IBD population. Ensuring disease remission prior to conception and throughout pregnancy is key for optimizing pregnancy and fetal outcomes. As gastroenterologists play an integral role in the management of IBD throughout the peripartum period, this review summarizes recent studies in combination with existing guidelines to address preconception counseling, medication safety, and management for quiescent and active disease throughout pregnancy.

Fertility and assisted reproductive technologies outcomes of women with non-surgically managed inflammatory bowel diseases: a systematic review

BACKGROUND AND AIM

In view of their frequent onset during childbearing years, the impact of inflammatory bowel diseases (IBD) on reproductive health is of important concern to young women and to the IBD physician. This study aims to assess the fertility and assisted reproductive technologies outcomes in non-surgically treated IBD female.

METHODS

A systematic review was conducted using MEDLINE, SCOPUS and EMBASE (until March 2022) to identify studies assessing fertility and assisted reproductive technologies outcomes in women with non-operated IBD, compared to non-IBD patients. Two reviewers independently selected studies, assessed risk of bias and extracted study data.

RESULTS

A total of 14 studies encompassing 18 012 patients with ulcerative colitis (UC) and 14 353 patients with Crohn's disease (CD) were included for analysis. The fertility rate in UC patients and in the general population was comparable, but UC patients tended to have fewer children, mainly by choice. On the contrary, the fertility of CD patients appeared to be reduced. Although a deliberate component cannot be not excluded, the disease itself could affect fertility. Disease activity was associated with reduced fertility in both UC and CD patients. In CD, the colonic involvement of the disease and perianal damage could be associated with subfertility, but data are less consistent. According to the only study reporting the assisted reproductive technologies outcomes, pregnancy rates after in vitro fertilization in subfertile non-operated UC patients and non-IBD patients were similar.

CONCLUSION

There is low-quality evidence from observational studies that patients with CD and relapsing UC may have impaired fertility. After assisted reproductive technologies, pregnancy rates of subfertile nonoperated UC patients were similar to those of the general population, although this observation requires further scrutiny in larger studies that should include UC and CD patients.

Ovarian reserve and IVF outcomes in patients with inflammatory bowel disease: A systematic review and meta-analysis

BACKGROUND

Inflammatory bowel disease (IBD) mainly affects people during reproductive age. However, it is unclear whether IBD might be associated with impaired ovarian reserve in female patients or with in vitro fertilization (IVF) outcomes.

METHODS

This systematic review and meta-analysis included articles from inception to May, 2022. Random-effect model was applied to calculate the standardized mean differences (SMDs) and odds ratios (ORs) and their 95% confidence intervals (95%CIs). Studies comparing the ovarian reserve or IVF outcomes of patients with IBD with the population were considered. To be included in this study, necessary measurements such as OR, relative risk (RR), SMD or hazard ratio (HR) or any necessary information to calculate them were provided in the articles. Letters, case reports, review articles including meta-analyses and expert opinions were excluded. For different articles studying the same population, the article with larger scale was selected.

FINDINGS

We included in our analysis 9 studies and data from 2386 IBD records and matched controls. Comparing with women without IBD, women with IBD had lower anti-mullerian hormone (AMH) levels (SMD = -0.38, 95%CI: -0.67, -0.09); (I2 = 79.0%, p = 0.000). Patients with IBD of different ages showed distinct ovarian reserves, with patients below 30 years old not showing any decline in ovarian reserve compared to the control group (SMD = -0.56, 95%CI: -2.28, 1.16); (I2 = 96.3%; p = 0.000), while patients with IBD over 30 years old (SMD = -0.75, 95%CI: -1.07, -0.43); (I2 = 0.0%; p = 0.608) showed a decline compared to control group. Patients with IBD in remission stage had similar ovarian reserves to population (SMD = -0.10, 95%CI: -0.32, 0.12); (I2 = 0.0%; p = 0.667), while patients in active stage showed an impaired ovarian reserve (SMD = -1.30, 95%CI: -1.64, -0.96); (I2 = 0.0%; p = 0.318). Patients with IBD showed a pregnancy rate after receiving IVF treatment comparable to the control population (OR = 0.87, 95%CI: 0.55, 1.37); (I2 = 70.1%, p = 0.035).

INTERPRETATION

The result of this study suggest that IBD may reduce reproductive age women's ovarian reserve and IVF treatment might help pregnancy outcomes in patients with impaired fertility. These results should be further validated in additional studies given the heterogeneity and quality of the studies included.

FUNDING

Inflammatory Bowel Disease and Reproductive Health: From Fertility to Pregnancy-A Narrative Review

Despite the fact that knowledge on obstetrical management of Inflammatory Bowel Diseases (IBDs) has greatly improved over the years, many patients still actively avoid pregnancy for fear of adverse maternal or neonatal outcomes, of adverse effects of pregnancy on the disease activity, of eventual IBD inheritance, or of an increased risk of congenital malformations. Indeed, though data prove that fertility is hardly affected by the disease, a reduced birth rate is nevertheless observed in patients with IBD. Misconceptions on the safety of drugs during gestation and breastfeeding may influence patient choice and negatively affect their serenity during pregnancy or lactation. Moreover, physicians often showed concerns about starting IBD medications before and during pregnancy and did not feel adequately trained on the safety of IBD therapies. IBD-expert gastroenterologists and gynecologists should discuss pregnancy and breastfeeding issues with patients when starting or changing medications in order to provide appropriate information; therefore, pre-conception counselling on an individualized basis should be mandatory for all patients of reproductive age to reassure them that maintaining disease remission and balancing the eventual obstetrical risks is possible.

Gastroenterology team members' knowledge and practices with fertility therapy for women with inflammatory bowel disease

INTRODUCTION

Fecundity may be reduced in women with active inflammatory bowel disease (IBD) or prior IBD-related surgery, and these women may require assisted reproductive technology (ART). There are no guidelines for women with IBD to outline referral criteria for ART.

METHODS

We performed a prospective, multicentre, international questionnaire of gastroenterologists, gastroenterology trainees, and IBD nurses. The primary outcome was to establish clinical practices and fertility therapy referral patterns among gastroenterology team members. We hypothesised that the lack of knowledge and awareness may delay or prevent initiation of fertility consultation referrals.

DISCUSSION

Of 182 participants, most had never initiated a referral for fertility therapy (69.8%), and of respondents who do initiate referrals, 50% wait until the patient has been unsuccessfully attempting conception for 12 months. Participants were significantly more likely to initiate a fertility therapy referral if they believed ART was effective (p = 0.038), not impeded by IBD-related surgery (p = 0.053), and if they had access to a dedicated IBD-pregnancy clinic (p = 0.027). Superior pregnancy knowledge was predictive of a greater likelihood of fertility therapy referrals (p = 0.037). All participants thought they had inadequate knowledge about ART in IBD, and 96.2% expressed desire to improve their knowledge.

CONCLUSION

Gastroenterology team members infrequently initiate referrals for fertility therapy consultation in women with IBD, increasing their risk of remaining childless. Implementation of dedicated IBD pregnancy clinics and targeted education programmes to increase awareness of ART in women with IBD might increase referral rates and reduce infertility.

Assisted Reproductive Technology in Crohn's Disease and Ulcerative Colitis: A Systematic Review and Meta-Analysis

INTRODUCTION

Infertility may occur in women with Crohn's disease (CD) and ulcerative colitis (UC), especially after surgery such as ileal pouch-anal anastomosis (IPAA). Assisted reproductive technology (ART) may be an option, but the safety and efficacy in this setting has been based on small cohorts to date. We performed a systematic review and meta-analysis to address this data gap.

METHODS

A systematic review and random-effects meta-analysis was performed until May 2020. The primary outcomes were pregnancy and live birth rates per cycle of ART.

RESULTS

Eleven studies met inclusion criteria for the systematic review and 4 for the meta-analysis. Compared with the general population, women with CD (with and without previous surgery) had no difference in pregnancy rates (odds ratio [OR] = 0.69, 95% confidence interval [CI]: 0.45-1.05) but had reduced live births (OR = 0.67, 95% CI: 0.53-0.85) per cycle of ART. ART live birth rates are not reduced in women with medically managed CD; however, they are 49%-71% lower after CD-related surgery. Women with UC had no difference in both pregnancy rates (OR = 0.99, 95% CI: 0.63-1.55) and live birth rates (OR = 0.88, 95% CI: 0.67-1.17); however, live birth rates were reduced after IPAA failure (hazard ratio = 0.36, 95% CI: 0.14-0.92). Two studies did not identify any significant safety signals.

DISCUSSION

ART is safe and effective in patients with UC and medically managed CD, with pregnancy and live birth rates similar to that of the general population. However, within the limitations of the available literature, current data suggest that efficacy is reduced in women with CD-related surgery and IPAA failure. Greater gastroenterologist awareness of ART is needed to facilitate timely fertility therapy referral when indicated, particularly in CD.

The impact of medical therapies and factors related to treatment procedures in women with rheumatoid arthritis and inflammatory bowel disease receiving assisted reproduction: a nationwide cohort study

OBJECTIVE

To examine whether medications used to treat rheumatoid arthritis (RA)/chronic inflammatory bowel disease (IBD), or factors related to the assisted reproductive technology (ART) procedures, impact the success of ART. In women with RA/IBD, initial studies have shown a reduced chance of a live-born child after ART.

DESIGN

Cohort study.

SETTING

Nationwide Danish health registries.

PATIENTS

All Danish women with a fresh embryo transfer from January 1, 2006, through 2018. The cohorts comprised 1,824 embryo transfers in women with RA/IBD and 97,191 embryo transfers in women without RA/IBD.

INTERVENTIONS

Observational, noninterventional study.

MAIN OUTCOME MEASURE

Live birth per fresh embryo transfer.

RESULTS

The chance of a live birth in women with RA/IBD receiving ART, compared with other women receiving ART, had an adjusted odds ratio (OR) of 0.79 (95% confidence interval [CI], 0.68-0.91). Prescribed corticosteroids before embryo transfer were positively associated with a live-born child (adjusted OR, 1.21; 95% CI, 1.12-1.31), while the use of antiinflammatory/immunosuppressive agents did not have significant importance. Intracytoplasmic sperm injection was associated with a reduced chance (adjusted OR, 0.94; 95% CI, 0.90-0.97). Type of hormone treatment protocol did not have significant importance, and transfer at the blastocyst stage was positively associated with a live-born child (adjusted OR, 1.54; 95% CI, 1.46-1.62).

CONCLUSIONS

In women with RA and/or IBD, prescribed corticosteroid before embryo transfer and embryo transfer at the blastocyst stage were associated with successful ART. Intracytoplasmic sperm injection was associated with a slightly reduced chance. Antiinflammatory/immunosuppressive agents and type of hormone protocols did not have significant importance.

The Efficacy of Assisted Reproduction in Women with a Wide Spectrum of Chronic Diseases - A Review

Assisted reproductive technology (ART) treatments in women with underlying chronic diseases have become increasingly frequent. The objective of this review is to provide an overview of the literature examining the chance of having a live born child after ART in women with chronic diseases, compared to other women receiving ART. We focused on some of the most prevalent chronic diseases in women during their reproductive years, ie ulcerative colitis, Crohn's disease, rheumatoid arthritis, multiple sclerosis, epilepsy, hyperthyroidism, hypothyroidism, and diabetes mellitus. Secondly, we studied the chance of successful implantation. The literature search was performed in the database Pubmed.gov. including all studies published before October 2020. Title and abstracts of 58 papers were reviewed, 37 papers were excluded and other 8 studies were excluded after full-text evaluation. Only 13 papers were eligible for review. Results indicate that women with ulcerative colitis, Crohn's disease, rheumatoid arthritis, hyperthyroidism, and diabetes mellitus type 2 might have problems with low implantation rate or early embryo development during ART. On the contrary, the few studies on women with hypothyroidism, diabetes mellitus type 1, and epilepsy suggest an equivalent chance of a live birth compared to other women undergoing ART. A possible explanation behind these differences could reside in the disease-specific dysregulation of the innate or adaptive immune system. To our knowledge, this is the first review on ART in women with chronic diseases, and it has disclosed that the evidence in this area is indeed sparse. We encourage others to examine live birth after ART in women with chronic diseases.

Review of pregnancy in Crohn's disease and ulcerative colitis

Inflammatory bowel disease (IBD) frequently affects women of childbearing age and can have implications in pregnancy. Most women with IBD have comparable fertility with women in the general population. Fertility is reduced in women with active disease or previous ileal-pouch-anal anastomosis (IPAA) surgery and is temporarily reduced in men taking sulfasalazine. Women with IBD have an increased risk of preterm delivery, low birth weight, small-for-gestational-age infants and Cesarean section (CS) delivery, however, no increased risk of congenital abnormalities. These adverse outcomes are particularly prevalent for women with active IBD compared with those with quiescent disease. Conception should occur during disease remission to optimize maternal and fetal outcomes and reduce the risk of disease exacerbations during pregnancy. Pre-conception counseling is therefore pertinent to provide patient education, medication review for risk of teratogenicity and objective disease assessment. Most medications are safe during pregnancy and breastfeeding, with the exception of methotrexate, ciclosporin, allopurinol and tofacitinib. Delivery modality should be guided by obstetric factors in most cases; however, CS is recommended for women with active perianal disease and can be considered for women with inactive perianal disease or IPAA. In conclusion, most women with IBD have uncomplicated pregnancies. Active IBD is the predominant predictor of poor outcomes and disease exacerbations; therefore, maintenance of disease remission during and before pregnancy is crucial.

Addressing delays in the diagnosis of pheochromocytoma/paraganglioma

Introduction: Pheochromocytomas/paragangliomas (PPG) are rare tumors. In theory the diagnosis of PPG should be straightforward. In clinical practice, however, considerable delays are noted in establishing such a diagnosis. Areas covered: We assess the characteristics of various approaches to diagnosis and localization of PPG lesions (and their relevant caveats). We also evaluate potential biases to diagnosis. Expert opinion: A high degree of suspicion - particularly in younger patients - is required by clinicians. The availability of diagnostic means (mainly of biochemical tools) to establish the diagnosis of PPG should be increased.
