Reproduction and Pregnancy in Inflammatory Bowel Disease - Management and Treatment Based on Current Guidelines

The Mediating and Moderating Role of Resilience Between Stigma and Illness Identity Among People with Inflammatory Bowel Disease

Background

Stigma is assumed to lead to negative illness identity in one who got chronic illness, and there is a lack of understanding regarding the underly mechanisms. However, no research has examined the extent to which stigma was associated with illness identity in people with IBD. Therefore, we investigated the relationship between stigma and illness identity, specifically to examine whether resilience mediated or moderated the relationship.

Methods

A cross-sectional study was performed among patients diagnosed with inflammatory bowel disease from three tertiary hospitals in Jiangsu Province, China. Measurement instruments included the Stigma Scale for Chronic Illness (SSCI), the Resilience Scale for Patients with Inflammatory Bowel Disease (RS-IBD), and the Illness Identity questionnaire (IIQ). Mediation and moderated mediation analyses were conducted.

Results

A total of 322 patients with IBD were involved in the current study. We observed that there was a strong connection between stigma and rejection and engulfment. Moreover, resilience played a partial or complete mediating role in stigma and engulfment, acceptance and enrichment, and resilience moderates the relationship between stigma and rejection.

Conclusion

The current study examined whether resilience mediated or moderated the relationship between stigma and illness identity. These finding add to the theoretical basis of how stigma influences illness identity and help guide the resilience into engulfment reduction programs for IBD.

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.

Comprehensive reproductive healthcare for women with immune-mediated inflammatory diseases: Addressing rheumatoid arthritis, spondyloarthritis and inflammatory bowel disease through life's stages

Immuno-mediated inflammatory diseases (IMIDs) such as rheumatoid arthritis, spondyloarthritis, and inflammatory bowel disease are characterised by pathophysiological mechanisms wherein the immune system erroneously targets the body's own tissues. This review explores the heightened vulnerability of women with IMIDs, influenced by hormonal modulators like estrogen and progesterone. The challenges this poses are multifaceted, encompassing the impact of active disease and medical treatments throughout life stages, including family planning, fertility, and menopause. From the perspectives of rheumatologists and gastroenterologists, we review current management strategies and underscore the need for a multidisciplinary and life-cycle approach to healthcare for women with IMIDs.

From the updated landscape of the emerging biologics for IBDs treatment to the new delivery systems

Inflammatory bowel diseases (IBDs) treatments have shifted from small-molecular therapeutics to the oncoming biologics. The first-line biologics against the moderate-to-severe IBDs are mainly involved in antibodies against integrins, cytokines and cell adhesion molecules. Besides, other biologics including growth factors, antioxidative enzyme, anti-inflammatory peptides, nucleic acids, stem cells and probiotics have also been explored at preclinical or clinical studies. Biologics with variety of origins have their unique potentials in attenuating immune inflammation or gut mucosa healing. Great advances in use of biologics for IBDs treatments have been archived in recent years. But delivering issues for biologic have also been confronted due to their liable nature. In this review, we will focus on biologics for IBDs treatments in the recent publications; summarize the current landscapes of biologics and their promise to control disease progress. Alternatively, the confronted challenges for delivering biologics will also be analyzed. To combat these drawbacks, some new delivering strategies are provided: firstly, designing the functional materials with high affinity toward biologics; secondly, the delivering vehicle systems to encapsulate the liable biologics; thirdly, the topical adhering delivery systems as enema. To our knowledge, this review is the first study to summarize the updated usage of the oncoming biologics for IBDs, their confronted challenges in term of delivery and the potential combating strategies.

Pregnancy outcomes in inflammatory bowel disease: Data from a large cohort survey

OBJECTIVES

Inflammatory bowel disease (IBD) can affect young and reproductively active patients. Our aim was to analyze pregnancy outcomes in a large cohort of women with IBD.

METHODS

All women with at least one pregnancy were given a questionnaire regarding the outcome of their pregnancy. They were divided into IBD pregnancies and controls depending on whether pregnancy occurred within or over 10 years prior to the diagnosis of IBD.

RESULTS

Three hundred questionnaires were analyzed for a total of 478 pregnancies that led to live-born babies. Age at conception was older in IBD women than in the controls. Active smoking was more frequent in the control group. The risk of intrauterine growth restriction (IUGR) was higher in IBD pregnancies (odds ratio [OR] 3.028, 95% confidence interval [CI] 1.245-7.370, P = 0.013). The week of gestation at delivery was lower in the IBD population. And the risk of cesarean section was higher in IBD pregnancies (OR 1.963, 95% CI 1.274-3.028, P = 0.002). Among women with IBD pregnancy, the risk of preterm birth was higher in patients with active disease at the time of conception (OR 4.088, 95% CI 1.112-15.025, P = 0.030), but lower in patients who continued regular therapy during pregnancy. Similarly, the risk of urgent cesarean section was reduced in the case of disease remission, while the risk of a planned cesarean delivery was higher in patients with perianal disease (OR 11.314, 95% CI 3.550-36.058, P < 0.01).

CONCLUSIONS

Our study shows a higher risk of IUGR, cesarean section, and poor blood pressure control in IBD pregnancies. We emphasize the importance of achieving disease remission before considering pregnancy.

Fertility and Pregnancy in Crohn's Disease

The prevalence of inflammatory bowel disease is continuing to increase worldwide and is more commonly diagnosed in women of reproductive age. Individuals with Crohn's disease may have inaccurate perceptions regarding the rate of infertility, heritability, and the safety of taking therapies for Crohn's disease during pregnancy, all of which greatly affect their decisions surrounding family planning. Given this area of need for both patients and providers, in this article, we have included the latest evidence on the impact of Crohn's disease on fertility, heritability, pregnancy outcomes, and the safety of medications for Crohn's disease during pregnancy and lactation.

Psoriasis and adverse pregnancy outcomes: A nationwide case-control study in 491,274 women in Denmark

Background

The chronic systemic inflammation associated with psoriasis supposedly creates an undesirable milieu for a pregnancy, resulting in an increased risk of adverse pregnancy outcomes (APOs).

Objective

To investigate the association between psoriasis and APOs as well as how the association differs according to psoriasis severity (mild and moderate-to-severe).

Methods

This nationwide register-based case-control study collected data from 1973 to 2017. Cases were APOs (spontaneous abortion, ectopic pregnancy [EP], intrauterine fetal death, and stillbirth). Singleton live births were controls. Adjusted logistic regression models were used for statistical analyses.

Results

In total, 42,041 (8.56%) APOs and 449,233 (91.44%) controls were included. EP was the only APO that was found to be statistically associated with psoriasis (odds ratio, 1.34; 95% CI, 1.06-1.68). Odds ratio for EP was the highest for women with moderate-to-severe psoriasis (odds ratio, 2.77; 95% CI, 1.13-6.76). The absolute risk of EP was 2.48% higher for women with moderate-to-severe psoriasis compared with women without psoriasis (3.98% vs 1.50%).

Limitations

No access to clinical data confirming psoriasis severity.

Conclusion

The present study found a significant association between EP and psoriasis (absolute risk of 3.98%). As EP is the leading cause of maternal morbidity and mortality in the first trimester of pregnancy, our findings call for particular care for women of reproductive age with psoriasis.

Thiopurine pharmacogenomics and pregnancy in inflammatory bowel disease

The thiopurine drugs azathioprine and 6-mercaptopurine are widely used for the maintenance of clinical remission in steroid-dependent inflammatory bowel disease (IBD). Thiopurines are recommended to be continued throughout pregnancy in IBD patients, but conclusive safety data in pregnant patients remain still insufficient. On the other hand, a strong association between a genetic variant of nucleoside diphosphate-linked moiety X-type motif 15 (NUDT15 p.Arg139Cys) and thiopurine-induced myelotoxicity has been identified. Pharmacokinetic studies have revealed that thiopurine metabolism is altered in pregnant IBD patients and suggested that the fetus may be exposed to the active-thiopurine metabolite, 6-thioguaninetriphosphate, in the uterus. A recent study using knock-in mice harboring the p.Arg138Cys mutation which corresponds to human p.Arg139Cys showed that oral administration of 6-MP at clinical dose induces a severe toxic effect on the fetus harboring the homozygous or heterozygous risk allele. This suggests that NUDT15 genotyping may be required in both women with IBD who are planning pregnancy (or pregnant) and their partner to avoid adverse outcomes for their infant. The risk to the fetus due to maternal thiopurine use is minimal but there are some concerns that are yet to be clarified. In particular, a pharmacogenomic approach to the fetus is considered necessary.

Sulfasalazine Sensitizes Polyhematoporphyrin-Mediated Photodynamic Therapy in Cholangiocarcinoma by Targeting xCT

Cholangiocarcinoma (CCA), which is highly malignant, shows a relatively poor prognosis, due to the insensitivity of the tumour to chemotherapy and radiotherapy. Photodynamic therapy (PDT) has become a promising palliative therapeutic option for patients with unresectable cholangiocarcinoma (CCA), while the functional amount of ROS is limited by intracellular redox systemen. Sulfasalazine (SASP), a well-known anti-inflammatory agent, which also acts as an inhibitor of the amino acid transport system xc (xCT), decreases the intracellular glutathione (GSH) level, thus weakening the antioxidant defence of the cell by inhibition of the antiporter. However, the combination of SASP and PDT remains unexplored. We have reported that polyhematoporphyrin (PHP)-mediated PDT inhibits the cell viability of CCA cells and organoids. Furthermore, in PHP-enriched HCCC-9810 and TFK-1CCA cells, SASP enhances the sensitivity to PHP-mediated PDT through a GSH-dependent mechanism. We found that PHP-PDT can up-regulate xCT expression to promote cells against overloaded ROS, while SASP reduces GSH levels. After the combination of SASP and PHP-PDT, cell viability and GSH levels were significantly inhibited. xCT was also observed to be inhibited by SASP in human organoid samples. Our findings suggest that, in combination with PDT, SASP has potential as a promising approach against CCA.

Association between Thiopurines Use and Pregnancy Outcomes in Female Patients with Inflammatory Bowel Disease: A Meta-Analysis

BACKGROUND

Conflicting data exist regarding the influence of thiopurines exposure on adverse pregnancy outcomes in female patients with inflammatory bowel disease (IBD).

OBJECTIVE

The aim of this study was to provide an up-to-date and comprehensive assessment of the safety of thiopurines in pregnant IBD women.

METHODS

All relevant articles reporting pregnancy outcomes in women with IBD received thiopurines during pregnancy were identified from the databases (PubMed, Embase, Cochrane Library, and ClinicalTrials.gov) with the publication data up to April 2020. Data of included studies were extracted to calculate the relative risk (RR) of multiple pregnancy outcomes: congenital malformations, low birth weight (LBW), preterm birth, small for gestational age (SGA), and spontaneous abortion. The meta-analysis was performed using the random-effects model.

RESULTS

Eight studies matched with the inclusion criteria and a total of 1201 pregnant IBD women who used thiopurines and 4189 controls comprised of women with IBD received drugs other than thiopurines during pregnancy were included. Statistical analysis results demonstrated that the risk of preterm birth was significantly increased in the thiopurine-exposed group when compared to IBD controls (RR, 1.34; 95% CI, 1.00-1.79; p=0.049; I² =41%), while no statistically significant difference was observed in the incidence of other adverse pregnancy outcomes.

CONCLUSION

Thiopurines used in women with IBD during pregnancy is not associated with congenital malformations, LBW, SGA, or spontaneous abortion, but appears to have an association with an increased risk of preterm birth.
