Use of tumor necrosis factor-alpha inhibitors during pregnancy among women who delivered live born infants

Current research and evidence gaps on placental development in iron deficiency anemia

Studying the effects of maternal iron deficiency anemia (IDA) is complex owing to its diverse causes, each independently impacting the placenta and fetus. Simple treatment with iron supplements does not always resolve the anemia. Therefore, delving into how IDA alters placental development at a molecular level is crucial to further optimize treatment. This review addresses the effects of IDA on placental structures and functions, including changes in oxygen levels, blood vessels, and the immune system. Profound understanding of physiological characteristics and regulatory mechanisms of placental development is key to explain the mechanisms of abnormal placental development in pregnancy-associated disorders. In turn, future strategies for the prevention and treatment of pregnancy complications involving the placenta can be devised. These studies are significant for improving human reproductive health, enhancing sociodemographic qualities, and even lifelong wellbeing, a focal point in future placental research.

The impact of the use of immunosuppressive treatment after an embryo transfer in increasing the rate of live birth

The tolerance of the immune system for the semi-allogeneic embryo is promoted by several factors and the cells involved in the immune system and factors in the mother during pregnancy. The dysregulation of the immune responses between the mother and fetus is a risk factor that raises the likelihood of rejection of the embryo and reproductive failure. To safeguard embryos and prevent immunological attacks, it is critical to suppress immunological rejection and encourage immunological tolerance. Based on current medical literature, it seems that immune cell management through immunosuppressive therapies can address reproductive failures. Immunosuppressive treatment has demonstrated encouraging results in terms of enhancing outcomes related to pregnancy and rates of live birth by regulating the immune responses of mothers and positively impacting the reproductive processes of humans. Currently, there is scarcity of high-quality data regarding the safety and efficacy of immunosuppressive therapies for children and mothers. Therefore, it is important to exercise caution while selecting use of any immunosuppressive therapy in pregnancy. This mini review provides a comprehensive overview of the existing literature regarding the impact of Calcineurin Inhibitors and anti-TNF treatment on improving the live birth rate following embryo transfer.

The US Food and Drug Administration Sentinel System: a national resource for a learning health system

The US Food and Drug Administration (FDA) created the Sentinel System in response to a requirement in the FDA Amendments Act of 2007 that the agency establish a system for monitoring risks associated with drug and biologic products using data from disparate sources. The Sentinel System has completed hundreds of analyses, including many that have directly informed regulatory decisions. The Sentinel System also was designed to support a national infrastructure for a learning health system. Sentinel governance and guiding principles were designed to facilitate Sentinel's role as a national resource. The Sentinel System infrastructure now supports multiple non-FDA projects for stakeholders ranging from regulated industry to other federal agencies, international regulators, and academics. The Sentinel System is a working example of a learning health system that is expanding with the potential to create a global learning health system that can support medical product safety assessments and other research.

Therapy of psoriasis during pregnancy and breast-feeding

There have been multiple systemic drugs approved for the therapy of psoriasis vulgaris and psoriasis arthritis (PsA) in the last decade. However, treatment decisions are difficult to make in women planning a pregnancy and in pregnant and lactating women due to the paucity of data for such cases. The strongest evidence for psoriasis therapy during pregnancy exists for topical corticosteroids. Medically controlled use of UVB-therapy is also considered safe. The best evidence regarding systemic therapy during pregnancy and lactation is available for the group of TNF-alpha inhibitors, which is also reflected in the respective medical product information. This is especially important in cases of psoriatic arthritis. Among traditional systemic therapeutics, the largest clinical experience exists for ciclosporin, which, if medically necessary, may be continued during gestation. However, TNF-alpha inhibitors, especially the pegylated form, should be preferred in case of pregnancy. Furthermore, an elective pregnancy termination is not necessary due to systemic therapy of psoriasis with many further substances during the first pregnancy weeks. The current work provides a comprehensive review of the scientific literature on treatment of psoriasis during pregnancy and lactation. Based on the available scientific information, severity of psoriasis and patient's comorbidities, the best possible therapeutic approach can be found in consensus with the patient.

Endometrial preparation with etanercept increased embryo implantation and live birth rates in women suffering from recurrent implantation failure during IVF

Recurrent implantation failure (RIF),  defined as ≥3 failed in vitro fertilization (IVF) cycles with the accumulated transfer of at least five embryos, plague many infertile women. The exact cause is unknown; however, evidence supports the immune system, specifically the Tumor Necrosis Factor (TNF) pathway. Etanercept (a TNFα antagonist) has been shown to improve pregnancy rates in women with rheumatoid arthritis or endometriomas; therefore, this study aimed to determine the effectiveness of etanercept for IVF in RIF women. Eighty-three RIF women were recruited from the Ingenes Institute in Mexico City for this single-arm, prospective study. All patients underwent a similar IVF protocol and received etanercept (4 × 25 mg every 72 h) after endometrial preparation, if applicable, and at embryo transfer. IVF endpoints assessed were embryo implantation (h-βCG >10 mg/dL at Day 14), the presence of a gestational sac, live birth, and birth weight. All women reported no side-effects associated with the etanercept treatment. 75.9 % of the cohort achieved embryo implantation, 74.7 % developed gestational sacs, and the ongoing pregnancy/live birth rate was at 62.7 %. However, 56.7 % of the live births were preterm (<37 weeks) and 60.5 % of the births were underweight (<2500 g). When stratified by fresh or frozen cycles or by the ova source (patient versus donor), the results were not significantly different with respect to the implantation rate, formation of gestational sacs, and the live birth rate. Here, we showed that using etanercept during endometrial preparation improves IVF outcomes in RIF women.

Leveraging the Capabilities of the FDA's Sentinel System To Improve Kidney Care

The Sentinel System is a national electronic postmarketing resource established by the US Food and Drug Administration to support assessment of the safety and effectiveness of marketed medical products. It has built a large, multi-institutional, distributed data network that contains comprehensive electronic health data, covering about 700 million person-years of longitudinal observation time nationwide. With its sophisticated infrastructure and a large selection of flexible analytic tools, the Sentinel System permits rapid and secure analyses, while preserving patient privacy and health-system autonomy. The Sentinel System also offers enhanced capabilities, including accessing full-text medical records, supporting randomized clinical trials embedded in healthcare delivery systems, and facilitating effective collection of patient-reported data using mobile devices, among many other research programs. The nephrology research community can use the infrastructure, tools, and data that this national resource offers for evidence generation. This review summarizes the Sentinel System and its ability to rapidly generate high-quality, real-world evidence; discusses the program's experience in, and potential for, addressing gaps in kidney care; and outlines avenues for conducting research, leveraging this national resource in collaboration with Sentinel investigators.

Fertility and infertility implications in rheumatoid arthritis; state of the art

BACKGROUND

A bulk of investigations imply that women with rheumatoid arthritis (RA) deliver fewer children in comparison to healthy women.

PURPOSE

This review article attempts to clarify the involvement of infertility-related issues in both RA men and women. Moreover, the effect of RA disease on the fertility quality and quantity will be discussed.

RESULTS

Declined fertility rate in RA women seems to stem from modified inflammatory settings, advanced maternal age, limited sexual activity, and adverse effects of drugs on ovarian function. Women with RA may have smaller families and seem to be slower to conceive relative to their peer women. The chance of gestation in RA women may drop due to suppressed sexual function through pain and fatigue. In addition, treatment of RA women with non-steroidal anti-inflammatory drugs (NSAIDs) may prevent ovulation and therefore hinder the conception.

CONCLUSIONS

A complex interaction between RA disease and fertility related issues is present. Despite an increase rate of infertility in RA females or males, the mechanisms involved in this outcome is still unknown. Plausible causes of the decreased fertility rate in RA patients might be due to inflammatory cytokines, suppressed sexual activity, drug treatments, mother age, personal choice, or a combination of these elements.

New changes in pregnancy and lactation labelling: Review of dermatologic drugs

Background

The U.S. Food and Drug Administration has published new pregnancy and lactation labelling rules that set standards on the presentation of information with regard to drug usage during pregnancy and breastfeeding, as well as the effects on fertility. These guidelines became effective June 30, 2015, and classified the risks of using prescription drugs during pregnancy in three detailed subsections: Pregnancy, Lactation, and Females and Males of Reproductive Potential. These sections describe the risks within a real-world context of caring for these patients.

Objective

In this study, we reclassified and categorized drugs and treatments commonly used in dermatology according to these new guidelines.

Methods

We performed a search of the medical literature about the use of relevant prescription drugs during pregnancy and breastfeeding and their effect on fertility. The search included prospective and retrospective studies, review articles from PubMed-indexed journals (from inception to November 2018), U.S. Food and Drug Administration records, pregnancy exposure registries, relevant information and studies provided in drug labeling by companies, and updated pharmacologic texts and guidelines up to 2018.

Results

Topical immunomodulators, systemic immunomodulators (including biologics), systemic antipruritic agents, antimicrobials, as well as acne, hair, and cosmetic agents were included. We have made best attempts to review and consolidate existing and new data and include them in our guide.

Conclusion

This new narrative format facilitates prescribing by considering a variety of factors. One previously overlooked aspect was the impact on the reproductive potential of both male and female patients. Rather than depending on overly simplistic letter risk categories, dermatologists will now need to make prescribing decisions based on each patient and the information provided, which will allow for better decision making and patient care.
