Managing IBD Therapies in Pregnancy

May ChatGPT be a tool producing medical information for common inflammatory bowel disease patients' questions? An evidence-controlled analysis

Artificial intelligence is increasingly entering everyday healthcare. Large language model (LLM) systems such as Chat Generative Pre-trained Transformer (ChatGPT) have become potentially accessible to everyone, including patients with inflammatory bowel diseases (IBD). However, significant ethical issues and pitfalls exist in innovative LLM tools. The hype generated by such systems may lead to unweighted patient trust in these systems. Therefore, it is necessary to understand whether LLMs (trendy ones, such as ChatGPT) can produce plausible medical information (MI) for patients. This review examined ChatGPT's potential to provide MI regarding questions commonly addressed by patients with IBD to their gastroenterologists. From the review of the outputs provided by ChatGPT, this tool showed some attractive potential while having significant limitations in updating and detailing information and providing inaccurate information in some cases. Further studies and refinement of the ChatGPT, possibly aligning the outputs with the leading medical evidence provided by reliable databases, are needed.

Echinacea purpurea (L.) Moench Polysaccharide Alleviates DSS-Induced Colitis in Rats by Restoring Th17/Treg Balance and Regulating Intestinal Flora

Echinacea purpurea is popularly used as a food supplement or nutritional supplement for its immune regulatory function against various threats. As one of its promising components, Echinacea purpurea (L.) Moench polysaccharide (EPP) has a wide range of biological activities. To evaluate the effect of EPP as a dietary supplement on ulcerative colitis (UC), this study used sodium dextran sulfate (DSS) to induce a UC model, extracted EPP using the ethanol subsiding method, and then supplemented with EPP by gavage for 7 days. Then, we evaluated the efficacy of EPP on DSS rats in terms of immunity, anti-inflammation, and intestinal flora. The result showed that EPP could alleviate colonic shortening and intestinal injury in rats with DSS-induced colitis, decrease the disease activity index (DAI) score, downregulate serum levels of inflammatory cytokines, and contribute to the restoration of the balance between the T helper cells 17 (Th17) and the regulatory T cells (Treg) in the spleen and mesenteric lymph nodes (MLNs). Meanwhile, EPP could downregulate the expression of Toll-like receptors 4 (TLR4), myeloid differentiation factor 88 (MyD88), and nuclear factor kappa-B (NF-κB) in colon tissue. In addition, the results of 16SrRNA sequencing showed that EPP also had a regulatory effect on intestinal flora of UC rats. These results indicate that EPP might achieve a beneficial effect on UC rats as a dietary supplement through restoring Th17/Treg balance, inhibiting the TLR4 signaling pathway and regulating intestinal flora, suggesting its possible application as a potential functional food ingredient alleviating UC.

Pregnancy and Inflammatory Bowel Disease: A Special Combination

Inflammatory bowel disease (IBD) comprises a spectrum of chronic immune-mediated diseases that affect the gastrointestinal tract. Onset typically occurs in early adulthood. The incidence of this disease has increased worldwide. Its prevalence has increased in Colombia and occurs predominantly in women. Considering that this disease is not curable, the main objective of management is to achieve remission. Many women are affected by IBD during different stages of their lives, including their reproductive life, pregnancy, and menopause. Because of this, the way the disease is managed in women of reproductive age can affect the course of IBD. Treatment and health maintenance strategies are very relevant; for patients with a desire to conceive, remission of the disease is very important at the time of conception and throughout the pregnancy to ensure adequate outcomes for both mother and fetus. Also, remission is necessary at least 3 months prior to conception. It is well known that active disease during conception and pregnancy is associated with adverse outcomes. In addition, active perianal disease is an indication of cesarean delivery, resulting in an increased risk of intestinal surgery and post-operative complications.

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.

Addressing pregnancy-related concerns in women with inflammatory bowel disease: Insights from the patient's perspective

Background and Aim

Therapeutic options for inflammatory bowel disease (IBD) have expanded, as has the use of IBD medications in women during the reproductive period. However, no qualitative data exist that examine the pregnancy‐related concerns of women with IBD in the current era of widespread immunomodulator and biologic use. Hence, we aimed to explore in detail the impact of IBD on pregnancy from the patient's perspective.

Methods

This qualitative study used semistructured interviews to explore participants' experiences regarding IBD and pregnancy until no new themes emerged. Key themes were identified using thematic analysis.

Results

Fifteen women with IBD were interviewed. The majority of participants reported lingering concerns regarding their IBD medications, despite advice from their gastroenterologist that the drugs were considered safe in pregnancy. Participants more often reported medication‐related fears, such as potential negative effects on their child's immune system, than concerns regarding the effect of the disease itself on their pregnancy outcomes. A common theme was a perceived lack of knowledge among non‐IBD clinicians regarding IBD medications during pregnancy, which augmented pre‐existing anxiety.

Conclusions

This study is the first of its kind to provide an in‐depth assessment of female patients' perspectives of IBD in relation to conception, pregnancy, and caring for offspring. In particular, this research characterizes the unique fears and persisting anxieties regarding IBD medications in pregnancy. The study has unearthed important insights into the specific concerns and support needs of women with IBD in order to facilitate nonjudgmental counseling designed around patient concerns and beliefs.

Mesalamine in the Initial Therapy of Ulcerative Colitis

Inflammatory bowel disease is a chronic disorder of intestinal inflammation and includes Crohn's disease and ulcerative colitis. The goal of therapy is to induce and maintain remission, which is achieved with conventional therapies. Mesalamine is considered a first-line therapy for ulcerative colitis. Clinical trials have confirmed its efficacy and safety in patients with mild to moderate ulcerative colitis. Doses of more than 2.4 g/d achieve significantly higher rates of clinical and endoscopic remission, with a decreased risk of relapse. Serious adverse effects are rare, but nonadherence is common. Mesalamine is considered safe in pregnancy, excluding formulations with dibutyl phthalate.

Pregnancy-Onset Acute Severe Colitis after in vitro Fertilization Embryo Transfer

Inflammatory bowel diseases (IBD) usually affect women in their fertile years and, therefore, have implications for their fertility and pregnancy. The presence of IBD during pregnancy has been shown to adversely affect pregnancy outcomes, and increased rates of preterm delivery and of spontaneous abortion have been reported. An onset of acute severe colitis in pregnancy has rarely been seen. We present the case of a 42-year-old woman who conceived after 9 attempts of in vitro fertilization and whose pregnancy was the result of a donated oocyte. Shortly after conception, she was diagnosed with severe active ulcerative colitis, and biologic therapy was introduced in the 28th week of pregnancy. Although therapy for IBD in pregnancy is considered safe for most drugs, this was not very well known in 2015. We also consider our case exceptional because we now have a 5-year follow-up of our patient and her child after having begun biologic therapy during late pregnancy.

Anti-TNF Exposure during Pregnancy in Crohn's Disease Patients

Inflammatory bowel disease (IBD) affects young people of reproductive age. Therefore, a broad discussion is needed about the possible disease effects in pregnancy, as well as the risks of fetal exposure to the medications used, especially biological therapy. This study aimed to describe the management of 4 Crohn's disease patients who received anti-TNF therapy during pregnancy and present a literature review. We reported 4 cases composed of young women who became pregnant while receiving anti-TNF agents. The patients presented a satisfactory response to the clinical treatment and the pregnancies progressed without complications. We did not observe maternal or embryonic toxicity, or unfavorable outcomes. The available data point to inflammatory activity as the main risk factor for unfavorable gestational evolution to date, and showed anti-TNF therapy to be safe during pregnancy and breastfeeding. However, the benefits and risks must be discussed with the patient and management decisions should be taken on an individual basis.
