Antirheumatic medications in pregnancy and breastfeeding. Curr Opin Rheumatol. 2020;32:238-246. [PMID: 32205567 DOI: 10.1097/bor.0000000000000710]

An interactive dose optimizer based on population pharmacokinetic study to guide dosing of methotrexate in Chinese patients with osteosarcoma

PURPOSE

Osteosarcoma is a rare tumor with an incidence of 4.4 cases per million per year in adolescent. High-dose methotrexate (HD-MTX) is the standard first-line chemotherapeutic agent for osteosarcoma. However, its efficacy can vary significantly among individuals due to wide pharmacokinetic variability. Despite this, only a few population pharmacokinetics (popPK) models based on Chinese patients with osteosarcoma have been reported. Thus, this study aimed to develop a HD-MTX popPK model and an individual model-based dose optimizer for osteosarcoma therapy.

METHOD

A total of 680 MTX serum concentrations from 57 patients with osteosarcoma were measured at the end of MTX infusion and 10 h, 24 h, 48 h, and 72 h after the start of infusion. Using the first-order conditional estimation method with NONMEM, a popPK model was estimated. Goodness-of-fit plots, visual predictive checks, and bootstrap analysis were generated to evaluate the final model. A dose optimizer tool was developed based on the validated models using R Shiny. Additionally, clinical data from 12 patients with newly diagnosed osteosarcoma were collected and used as the validation set to preliminarily verify the predictive ability of the popPK model and the dose optimizer tool.

RESULTS

Body surface area (BSA) was the most significant covariate for compartment distribution. Creatinine clearance (CrCL) and co-administration of NSAIDs were introduced as predictors for central compartmental and peripheral compartmental clearance, respectively. Co-administration of NSAIDs was associated with significantly higher MTX concentrations at 72 h (p = 0.019). The dose optimizer tool exhibited a high consistency in predicting MTX AUC compared to the actual AUC (r = 0.821, p < 0.001) in the validation set.

CONCLUSION

The dose optimizer tool could be used to estimate individual PK parameters, and optimize personalized MTX therapy in particular patients.

Cardiovascular complications during pregnancy: Advancing cardio-obstetrics

As the incidence of cardiovascular diseases (CVDs) continues to rise among women of childbearing age, the pregnant population with pre-existing heart conditions presents a complex and heterogeneous profile. These women face varying degrees of risk concerning maternal cardiovascular, obstetric, and fetal complications. Effectively managing adverse cardiovascular events during pregnancy presents substantial clinical challenges. The uncertainties surrounding diagnostic and therapeutic approaches create a dynamic landscape with potential implications for maternal and fetal health. Cardio-obstetrics has become increasingly recognized as a vital multidisciplinary field necessitating a collaborative approach to managing cardiovascular conditions during pregnancy. In this review, we aim to provide a thorough and up-to-date examination of the existing evidence, offering a comprehensive overview of strategies and considerations in the management of cardiovascular complications during pregnancy. Special emphasis is placed on the safety assessment of diagnostic procedures and the exploration of treatment options designed to prioritize the well-being of the mother and fetus. We also explore the significance of a multidisciplinary cardio-obstetrics team in providing comprehensive care for women of childbearing age with or at risk for CVD.

Real-world pharmacological treatment of pregnant patients with rheumatic diseases from China: a retrospective analysis from 2016 to 2021

Introduction: We investigated trends in the use of therapeutic drugs for pregnant patients with rheumatic diseases in nine Chinese cities (Beijing, Chengdu, Guangzhou, Harbin, Hangzhou, Shanghai, Shenyang, Tianjin, and Zhengzhou) to provide a reference for drug use in clinic. Methods: Outpatient prescription data for pregnant patients diagnosed with rheumatic diseases in nine cities across China in 2016-2021 were extracted from the Hospital Prescription Cooperation Project of the Hospital Pharmacy Professional Committee of the Chinese Pharmaceutical Association. A retrospective analysis was then performed, incorporating data on patient age, defined daily doses (DDDs), defined daily cost (DDC), and other metrics. Results: In 2016-2020, more than 70% of the pregnant patients diagnosed with rheumatic diseases in these nine cities were 25 to < 35 years of age. The most common rheumatic diseases during pregnancy were antiphospholipid antibody syndrome (APS) and systemic lupus erythematosus (SLE). In terms of the routine use of daily therapeutic drugs, the DDDs of low molecular weight heparins (LMWHs), glucocorticoids, and immunosuppressive agents dominated the top three. Intravenous immunoglobulin (IVIG) and tumor necrosis factor inhibitors (TNFi) have been used since 2019 and had been in the forefront of the DDC. Conclusion: The number and total cost of prescriptions for therapeutic drugs of pregnancy complicated by rheumatic diseases, have increased significantly over the study interval. Conventional therapeutic drugs, especially glucocorticoids, LMWHs, and hydroxychloroquine were the most widely used drugs in pregnant patients with rheumatic diseases. However, IVIG and TNFi, relatively high cost, have shown gradual increases in clinical use since 2019.

Psoriatic Arthritis Involving TMJ: A Review on Pathogenesis and Consideration on Eventual Gender Differences

Psoriatic arthritis is defined as chronic inflammatory arthritis associated with psoriasis. The current data regarding gender differences in clinical manifestation and therapeutic outcomes of psoriatic arthritis are limited. Generally, men show a peripheral disease manifestation, while women have an axial distribution of the lesions. If we look at temporomandibular joint (TMJ) involvement, epidemiological data on the involvement of the TMJ are hard to find. Few studies on therapeutic management and the related impact on the quality of life are reported in the literature. Given the morpho-functional peculiarities of the TMJ and the different pain burdens between male and female genders, when manifestation of psoriatic arthritis occurs, clinicians should face it using a multidisciplinary approach for a correct diagnosis and successful treatment. This review aims to examine the diagnostic signs of psoriatic arthritis in the TMJ, the eventual variations of this disease in male and female patients, and the therapeutical strategies. The coordination of different specialties is fundamental to the remission of clinical symptoms and lesion regression.

The effects of hydroxychloroquine and its promising use in refractory obstetric antiphospholipid syndrome

Hydroxychloroquine (HCQ) is obtained by hydroxylation of chloroquine (CQ) and the first indication was malaria. Nowadays, HCQ is commonly used in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) with favorable results. Antiphospholipid syndrome (APS) is an autoimmune disease characterized by thrombosis and/or pregnancy morbidity and persistent positivity of antiphospholipid antibodies. Around 20-30% of pregnant women with APS develop adverse pregnancy outcomes despite conventional treatment with aspirin and heparin, called refractory obstetric APS. Interestingly, HCQ has shown positive effects on top of the standard of care in some refractory obstetric APS patients. HCQ mechanisms of action in APS comprise its ability to bind sialic acid present in cell membranes, its capacity to block the binding of antiphospholipid antibodies to the cell and the induced increase of pH in extracellular and intracellular compartments. However, the precise mechanisms of HCQ in the specific situation of refractory APS still need to be fully clarified. Therefore, this review summarizes the known modulating effects of HCQ and CQ, their side effects and use in APS and different pathologies to understand the benefit effects and the mechanism of action of HCQ in refractory obstetric APS.

Immunosuppressive and immunomodulating therapy for atopic dermatitis in pregnancy: an appraisal of the literature

Atopic dermatitis (AD) is the most common dermatological diagnosis during pregnancy. Treatment of AD during pregnancy can be challenging, due to the unpredictable course and the fact that the therapy needs to be safe for both the mother and the fetus. Here we present an up-to-date appraisal of the literature on the treatment options available for AD in patients planning pregnancy, during pregnancy, and during breastfeeding. All patients with AD are recommended to supplement any medical treatment with daily applications of emollients. The first step in the medical treatment for AD during pregnancy are topical corticosteroids, and/or topical tacrolimus. If required, UV-light therapy can also be considered. Treatment with systemic therapy during pregnancy should always rely on a careful risk-benefit assessment and be based on shared-decision making between the treating physician and patient. The first-line systemic treatment option is cyclosporine A, whereas azathioprine may be considered in patients already receiving this treatment prior to pregnancy. Systemic glucocorticoids may also be used. Treatment with systemic JAK inhibitors is not recommended, whereas treatment with mycophenolate mofetil and methotrexate is contraindicated. Targeted therapy with dupilumab is not generally recommended, due to lack of experience in human pregnancies, yet some case-reports on their use are emerging. These recommendations are based on the authors appraisal of existing literature and the current recommendation from the European Task Force on Atopic Dermatitis. It is always the responsibility of the treating physician to stay updated on the newest guidelines and literature when treating patients with AD during pregnancy.

Blockade of IL-6R prevents preterm birth and adverse neonatal outcomes

BACKGROUND

Preterm birth preceded by spontaneous preterm labour often occurs in the clinical setting of sterile intra-amniotic inflammation (SIAI), a condition that currently lacks treatment.

METHODS

Proteomic and scRNA-seq human data were analysed to evaluate the role of IL-6 and IL-1α in SIAI. A C57BL/6 murine model of SIAI-induced preterm birth was developed by the ultrasound-guided intra-amniotic injection of IL-1α. The blockade of IL-6R by using an aIL-6R was tested as prenatal treatment for preterm birth and adverse neonatal outcomes. QUEST-MRI evaluated brain oxidative stress in utero. Targeted transcriptomic profiling assessed maternal, foetal, and neonatal inflammation. Neonatal biometrics and neurodevelopment were tested. The neonatal gut immune-microbiome was evaluated using metagenomic sequencing and immunophenotyping.

FINDINGS

IL-6 plays a critical role in the human intra-amniotic inflammatory response, which is associated with elevated concentrations of the alarmin IL-1α. Intra-amniotic injection of IL-1α resembles SIAI, inducing preterm birth (7% vs. 50%, p = 0.03, Fisher's exact test) and neonatal mortality (18% vs. 56%, p = 0.02, Mann-Whitney U-test). QUEST-MRI revealed no foetal brain oxidative stress upon in utero IL-1α exposure (p > 0.05, mixed linear model). Prenatal treatment with aIL-6R abrogated IL-1α-induced preterm birth (50% vs. 7%, p = 0.03, Fisher's exact test) by dampening inflammatory processes associated with the common pathway of labour. Importantly, aIL-6R reduces neonatal mortality (56% vs. 22%, p = 0.03, Mann-Whitney U-test) by crossing from the mother to the amniotic cavity, dampening foetal organ inflammation and improving growth. Beneficial effects of prenatal IL-6R blockade carried over to neonatal life, improving survival, growth, neurodevelopment, and gut immune homeostasis.

INTERPRETATION

IL-6R blockade can serve as a strategy to treat SIAI, preventing preterm birth and adverse neonatal outcomes.

Safety and effectiveness of bDMARDs during pregnancy in patients with rheumatic diseases: Real-world data from the BIOBADASER registry

INTRODUCTION

Inflammatory rheumatic diseases usually affect women of childbearing age treated with biologic drugs. However, there is a lack of literature on the efficacy and toxicity of biologic disease-modifying drugs during pregnancy. The aim of this study was to determine the presence of pregnant patients treated with bDMARDs in a real-world dataset and to examine the impact of pregnancy and lactation on the evolution of rheumatic disease in a registry of Spanish patients.

METHOD

This was a multicentre prospective study with a real-world setting. Information was obtained from BIOBADASER registry. Patients included are women who got pregnant until November 2020 from 19 rheumatology units. We conducted proportions, means, and standard deviations (SD) to describe the study population and the use of treatments. T-test and Chi-square test were applied to assess differences between groups.

RESULT

Ninety cases of pregnancy were registered (n=68 full-term pregnancies; n=22 spontaneous miscarriages). Most of the cases discontinued bDMARDs during pregnancy (78.9%) but 13 cases continued treatment during pregnancy, mainly using certolizumab pegol. These cases were obtaining better management of rheumatic disease, although the differences were not statistically significant [DAS28-CRP, 2.9 (SD: 1.6) vs. 2.0 (1.2), p=.255; DAS28-ESR, 2.2 (1.0) vs. 1.7 (.5), p=.266]. No serious adverse events were reported during pregnancy and lactation.

CONCLUSION

Being pregnant is still an uncommon condition in patients with rheumatic diseases and using bDMARDs. Our results show that rheumatic disease tended to progress better during pregnancy in patients who continued to take bDMARDs.

Pericarditis Management in Individuals Contemplating Pregnancy, Currently Pregnant, or Breastfeeding

PURPOSE OF REVIEW

Pericarditis complicates pregnancy planning, pregnancy, or the postpartum period, and the management approach requires special considerations. Here, we aim to summarize the latest research, diagnostic, and treatment strategies.

RECENT FINDINGS

Physiologic cardiovascular (CV) adaptations occurring during pregnancy complicate diagnosis, but for most patients, an electrocardiogram (ECG) and transthoracic echocardiogram (TTE) are sufficient to diagnosis pericarditis in the appropriate clinical context. Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) can be used until 20 weeks gestation as needed. The use of colchicine is encouraged at any time point to reduce the risk of recurrence. Glucocorticoids may be used at the lowest possible dose for the least amount of time throughout pregnancy and breastfeeding. For incessant, recurrent, or refractory pericarditis, or when the above therapies are contraindicated, there may be a consideration of the use of IL-1 inhibition during pregnancy, recognizing the limited data in pregnant patients. Finally, we encourage the use of a multidisciplinary team approach including OB-GYN, cardiology, and rheumatology when available. The diagnosis and treatment of pericarditis in female patients of reproductive age require special considerations. Although highly effective treatment options are available, there is a need for greater data and larger international registries to improve treatment recommendations.

Drug switching in axial spondyloarthritis patients in Germany - a social listening analysis

Background

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease which primarily affects the axial skeleton resulting in chronic back pain and stiffness. According to the guideline, the first-line treatment includes non-steroidal anti-inflammatory drugs (NSAIDs), conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and non-pharmacological treatment. Second line treatment involves biological disease-modifying antirheumatic drugs (bDMARDs) such as tumour necrosis factor and interleukin-17 inhibitors.

Objectives

The aim of this social media listening research project was to analyse switches of medication and the reasons thereof to gain valuable insights into real-life journeys of patients suffering from axSpA.

Methods

Publicly available posts in German-speaking disease-specific forums were scanned for disease-specific keywords and commonly used drugs by axSpA patients on the Permea platform. Posts containing at least two key words were selected and switches between medications were manually labelled. A total of 287 scraped posts between 01 July 2010 and 04 Feb 2022 were analysed.

Results

The largest group of described medication switches was initially using bDMARDs. Switches to a different bDMARD, termination of medication and switches to glucocorticoids were most frequently named. Patients on NSAIDs switched to glucocorticoids, a different NSAID or bDMARD, whereas patients on csDMARDs most frequently changed to bDMARDs. In all medication groups the main reason for switching was insufficient efficacy and side effects. Additionally, for the medication groups bDMARDs, csDMARDs and corticosteroids, pregnancy and lactation were given as a reason for switching, whereas patients in the NSAID group never mentioned pregnancy and breastfeeding as a reason for switching treatment.

Conclusion

Our analysis shows medication switches based on real-life patient experiences shared with peers in a social listening setting. We also show medication switches differing from advised guidelines. Gathering real-life insights into patients' journey dealing with chronic diseases allows us to understand, and thereby improve patient care and treatment.

Perspectives on Mycophenolate Mofetil in the Management of Autoimmunity

Before becoming a cornerstone in the treatment of numerous immune-mediated diseases, mycophenolate mofetil (MMF) was first introduced as an immunosuppressive agent in transplant immunology and later received the attention of rheumatologists and clinicians involved in the management of autoimmune diseases. MMF is now a widespread immunosuppressive drug for the treatment of several conditions, including lupus nephritis, interstitial lung disease associated with systemic sclerosis, and anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis while being efficacious also as rescue therapy in various orphan diseases, including dermatomyositis and IgA-associated nephropathy. Similarly, case reports or series support a possible use of MMF in other rare autoimmune diseases. Beyond modulating lymphocyte activation, MMF acts on other immune and non-immune cells and these effects may explain the therapeutic profile of this medication. The effects of MMF are broadly characterized by the impact on the immune system and the antiproliferative and antifibrotic changes induced. In this latter case, mechanistic data on fibroblasts may in the future allow to reevaluate the use of MMF in selected patients with inflammatory arthritis or systemic sclerosis. Attention must be paid towards the possible occurrence of adverse events, such as gastrointestinal complaints and teratogenicity, while the risk of infections and cancer related to MMF needs to be further investigated.

Australian inflammatory bowel disease consensus statements for preconception, pregnancy and breast feeding

OBJECTIVE

Because pregnancy outcomes tend to be worse in women with inflammatory bowel disease (IBD) than in those without, we aimed to update consensus statements that guide the clinical management of pregnancy in patients with IBD.

DESIGN

A multidisciplinary working group was established to formulate these consensus statements. A modified RAND/UCLA appropriateness method was used, consisting of a literature review, online voting, discussion meeting and a second round of voting. The overall agreement among the delegates and appropriateness of the statement are reported.

RESULTS

Agreement was reached for 38/39 statements which provide guidance on management of pregnancy in patients with IBD. Most medications can and should be continued throughout pregnancy, except for methotrexate, allopurinol and new small molecules, such as tofacitinib. Due to limited data, no conclusion was reached on the use of tioguanine during pregnancy. Achieving and maintaining IBD remission before conception and throughout pregnancy is crucial to optimise maternofetal outcomes. This requires a multidisciplinary approach to engage patients, allay anxieties and maximise adherence tomedication. Intestinal ultrasound can be used for disease monitoring during pregnancy, and flexible sigmoidoscopy or MRI where clinically necessary.

CONCLUSION

These consensus statements provide up-to-date, comprehensive recommendations for the management of pregnancy in patients with IBD. This will enable a high standard of care for patients with IBD across all clinical settings.

Treatment considerations in myasthenia gravis for the pregnant patient

INTRODUCTION

Myasthenia gravis (MG) is an autoimmune disease where muscle antibodies form against the acetylcholine receptor (AChR), MuSK, or LRP4 at the neuromuscular junction leading to weakness. Patients worry about consequences for pregnancy, giving birth, nursing, and child outcome.

AREAS COVERED

This review lists the pharmacological treatments for MG in the reproductive age and gives recommendations. Consequences for pregnancy, giving birth, breastfeeding, and child outcome are discussed.

EXPERT OPINION

Pyridostigmine, corticosteroids in low doses, and azathioprine are regarded as safe during pregnancy and should be continued. Mycophenolate mofetil, methotrexate, and cyclophosphamide should not be used in reproductive age. Rituximab should not be given during pregnancy. Other monoclonal IgG antibodies such as eculizumab and efgartigimod should be given only when regarded strictly necessary to avoid long-term and severe incapacity. Intravenous and subcutaneous immunoglobulin and plasma exchange are safe treatments during pregnancy and are recommended for exacerbations with moderate or severe generalized weakness. Most MG women have spontaneous vaginal deliveries. Indications for Cesarean section are obstetrical and similar to non-MG women. Neonatal myasthenia manifests as a transient weakness caused by the mother's IgG muscle antibodies and affects 10% of the babies. MG women should be supported in their wish to have children.

Diverse effects of α-/β-estradiol on catalytic activities of human UDP-glucuronosyltransferases (UGT)

β-estradiol (β-E2) and α-estradiol (α-E2) act as an endo- and an exon-estrogen in humans, respectively. There is a structural variation in C17-OH configuration of the two estrogens. UDP-glucuronosyltransferases (UGT) are responsible for termination of activities of a variety of endogenous hormones, clinical drugs, and environmental toxicants. The current study was conducted to investigate the effects of the two estrogens towards catalytic activities of UGTs. It was found that β-E2 could decrease activities of UGT1A9, - 2B4 and - 2B7, with K_i values of a few micro-molars. β-E2 could additionally accelerate the activity of UGT2B17 via promoting enzyme-substrate binding and increasing the turn over number. Comparatively, α-E2 displayed much stronger inhibitory potentials towards UGT2B7 and - 2B4, but showed little influence to UGT1A9 and - 2B17. The K_i values for inhibition of UGT2B7 in glucuronidation of different substrates by α-E2 were in a nanomolar range that is only about 1/100-1/50 of β-E2. UGT2B7 structural model was fatherly constructed to explore the mechanism underlying dramatically different inhibition selectivity of the two estrogens. Compared to β-E2, α-E2 formed more hydrophobic and hydrogen-bonded interactions with the residues in the active pocket. It is concluded that the configuration of E2-17-OH determines the inhibitory potentials towards UGTs. The results are useful in better understanding ligand selectivity of UGTs, as well as in further development of α-E2 in health protection.

The Use of Azathioprine in Atopic Dermatitis. A Review

Most patients with atopic dermatitis (AD) have a good response to topical treatment. However, some need systemic therapy in order to satisfactorily control the disease. Azathioprine is an accessible drug for patients in many countries, including underdeveloped countries, and therefore it's used by many dermatologists in moderate and severe AD. It is important to have a deep knowledge and understanding about this drug since it is an alternative therapy as a steroid-sparing agent and an affordable one. However, when it comes to systemic therapy for AD, it's not always clear its indications and it is necessary to have a closer follow-up of the patient. In this paper we describe thoroughly it's indications in AD, the mechanism of action of the drug, as well as the interactions, adverse effects, adequate monitoring, and precautions in special population that must be considered when prescribing azathioprine. This review will help dermatologists prescribe it safely to all patients who require it. This article is protected by copyright. All rights reserved.

Mothers' experiences of wellbeing and coping while living with rheumatoid arthritis: a qualitative study

Background

Rheumatoid arthritis (RA) can result in difficulties for mothers when undertaking daily care activities and increased psychological distress. However, few studies have examined how women with RA subjectively experience coping and wellbeing as part of their motherhood.

Methods

Twenty mothers with a diagnosis of RA and a dependent child (18 years or younger) who were living in Australia took part in a semi-structured interview between June and November 2017. Purposive sampling was undertaken to include participants across degree of current RA severity, number and age of children, and having received a diagnosis before or after a first child to take account of variability across these experiences. A qualitative thematic analysis was conducted on the interview transcripts.

Results

The following themes were identified: ‘Burden and complexity in the mothering role’, ‘Losing control: Women’s experiences of distress’, and ‘Adjusting and letting go: Women’s experiences of wellbeing’. Experiences of distress, including feelings of failure, were associated with accounts of a loss of control over mothering practices among women, regardless of child age. In contrast, accounts of adjusting mothering practices and relinquishing control were associated with reports of enhanced wellbeing. In addition, some mothers reported greater ease due to increased independence of older children. The absence of social support exacerbated burden and distress in the women’s accounts, while the availability of support alleviated burden and was associated with reports of wellbeing.

Conclusion

Health professionals and services can provide support to mothers with RA by addressing feelings of failure, acknowledging strategies of adjustment and letting go, and encouraging access to social support.

Heart Failure Subtypes and Cardiomyopathies in Women

Heart failure affects over 2.6 million women and 3.4 million men in the United States with known sex differences in epidemiology, management, response to treatment, and outcomes across a wide spectrum of cardiomyopathies that include peripartum cardiomyopathy, hypertrophic cardiomyopathy, stress cardiomyopathy, cardiac amyloidosis, and sarcoidosis. Some of these sex-specific considerations are driven by the cellular effects of sex hormones on the renin-angiotensin-aldosterone system, endothelial response to injury, vascular aging, and left ventricular remodeling. Other sex differences are perpetuated by implicit bias leading to undertreatment and underrepresentation in clinical trials. The goal of this narrative review is to comprehensively examine the existing literature over the last decade regarding sex differences in various heart failure syndromes from pathophysiological insights to clinical practice.

Pathogenesis, Diagnosis and Management of Obstetric Antiphospholipid Syndrome: A Comprehensive Review

Antiphospholipid syndrome is an autoimmune disorder characterized by vascular thrombosis and/or pregnancy morbidity associated with persistent antiphospholipid antibody positivity. Cases fulfilling the Sydney criteria for obstetric morbidity with no previous thrombosis are known as obstetric antiphospholipid syndrome (OAPS). OAPS is the most identified cause of recurrent pregnancy loss and late-pregnancy morbidity related to placental injury. Cases with incomplete clinical or laboratory data are classified as obstetric morbidity APS (OMAPS) and non-criteria OAPS (NC-OAPS), respectively. Inflammatory and thrombotic mechanisms are involved in the pathophysiology of OAPS. Trophoblasts, endothelium, platelets and innate immune cells are key cellular players. Complement activation plays a crucial pathogenic role. Secondary placental thrombosis appears by clot formation in response to tissue factor activation. New risk assessment tools could improve the prediction of obstetric complication recurrences or thromboses. The standard-of-care treatment consists of low-dose aspirin and prophylactic low molecular weight heparin. In refractory cases, the addition of hydroxychloroquine, low-dose prednisone or IVIG improve pregnancy outcomes. Statins and eculizumab are currently being tested for treating selected OAPS women. Finally, we revisited recent insights and concerns about the pathophysiology, diagnosis and management of OAPS.

Sulfasalazine exposure during pregnancy and lactation induces alterations in reproductive behavior in adult female rat offspring

AIMS

Sulfasalazine (SAS) is the first line drug in the treatment of chronic inflammatory bowel diseases in pregnant women. SAS and its metabolites cross the placenta and can be transferred through the milk. However, the long-term consequences to the reproductive system of offspring from dams exposed to SAS have not yet been studied. Thus, our study investigated the effects of SAS treatment during gestational and lactational periods on maternal care in F0 and reproductive outcomes in F1 females.

MAIN METHODS

Wistar female rats (n = 10/group) received 300 mg/kg/day of SAS dissolved in carboxymethyl cellulose (CMC), by gavage, from gestational day 0 to lactation day 21 and 3 mg/kg/day of folic acid during gestation. The control group received CMC only. On PND 21, the female pups were selected for reproductive evaluation at different time points: infancy and adulthood. The reproductive parameters evaluated were installation of puberty (vaginal opening and first estrus), estrous cyclicity, reproductive organs weight, histological analysis of the ovary follicles and uterus, analysis of oxidative stress in ovarian tissue, reproductive behavior (sexual and maternal), and fertility.

KEY FINDINGS

SAS treatment decreased the retrieving behavior in F0 females. The F1 females presented an increase in the lordosis score, frequency of lordosis of magnitude 3, and lipid peroxidation of ovarian tissues in both infancy and adult life.

SIGNIFICANCE

The SAS effects observed in the current study represent a relevant concern for public health, as they demonstrated that treatment with SAS compromised the maternal motivation of dams and induced reproductive alterations in F1 females.

The Potential Benefit of Hydroxychloroquine in Chronic Placental Inflammation of Unknown Etiology Associated with Adverse Pregnancy Outcomes

The placenta is the site of connection between maternal and fetal circulation, and the liaison is established early in pregnancy. A large variety of pregnancy complications such as preterm birth, fetal growth restriction, or pregnancy loss have placental expression and can be accompanied in some cases of acute or chronic identifiable placental inflamatory lesions. Chronic placental inflammatory (CPI) lesions include chronic villitis of unknow etiology (CVUE), chronic intervillositis of unknown etiology, CIUE (also described as chronic histiocytic intervillositis, CHI), and chronic deciduits. Hydroxychloroquine (HCQ) has been prescribed with good results during pregnancy to prevent adverse perinatal outcomes in maternal autoimmune conditions. Its success has paved the way to its use in CPI as CIUE/CHI; however, to date, there are no prospective, informatively designed, controlled studies on its value in these setting. This review aims to explore the potential role of HCQ in CPI of unknown etiology. Ideally, properly designed, probably multicentric studies should be undertaken to fully understand HCQ's role for prevention of adverse pregnancy outcomes after a chronic placental inflammation.

The Safety of Medications During Pregnancy and Lactation in Patients with Inflammatory Rheumatic Diseases

The advances in treatments, including disease-modifying anti-rheumatic drugs and biologic agents, have significantly improved the management of inflammatory rheumatic diseases, allowing females with severe disease to become pregnant and lactate, previously considered as prohibited. Maintaining low disease activity with medications known to be safe from pre-conception to post-partum is a key point in reducing adverse pregnancy outcomes. Numerous observational and case studies have provided a growing amount of evidence on the use of safe anti-rheumatic medications in patients during pregnancy and lactation. Based on this information, this review discusses the safety of medications for patients with inflammatory rheumatic diseases during pregnancy and lactation. Among these, hydroxychloroquine, sulfasalazine, azathioprine, low-dose glucocorticoids, and low-dose aspirin are considered compatible with pregnancy, while methotrexate, cyclophosphamide, mycophenolate mofetil, and leflunomide are contraindicated. Non-steroidal anti-inflammatory drugs are only recommended for use early in pregnancy, as they are reported to cause rare but serious kidney problems in the fetus after 20 weeks or later. Cyclosporin, tacrolimus, and anti-TNF agents can be continued throughout pregnancy if the benefit is greater than the potential risk for the individual patient. Physicians should carefully weigh the risks and benefits of medications in patients with inflammatory rheumatic diseases considering pregnancy.

Safety of long-term use of four common conventional disease modifying anti-rheumatic drugs in rheumatoid arthritis

Conventional disease-modifying antirheumatic drugs (DMARDs) have been used in the management of rheumatoid arthritis for a long time. Whereas methotrexate (MTX) is the anchor drug, leflunomide, hydroxychloroquine and sulfasalazine are used along with MTX either in combination or sequentially. Together these four drugs are the most commonly used DMARDs. They are also used in combination with biological DMARDs (bDMARDs) to enhance their efficacy and MTX in particular to reduce antibodies against anti-tumour necrosis factor. Despite their widespread use, concerns regarding their safety especially when used long-term hinder their optimum use in clinical medicine. In this narrative review we have critically appraised the available literature regarding the safety of these four DMARDs when used long-term.

The impact of hydroxychloroquine on obstetric outcomes in refractory obstetric antiphospholipid syndrome

BACKGROUND

The use of low-dose aspirin (LDA) and heparin has improved pregnancy outcomes in women with antiphospholipid syndrome (APS). However, 20-30% still have adverse outcomes despite treatment. Recent retrospective studies showed a beneficial effect of hydroxychloroquine (HCQ) in APS due to its anti-inflammatory, immunomodulatory and antithrombotic properties. Data in refractory obstetric APS (OAPS) remain scarce and include heterogeneous populations with various concomitant treatments.

OBJECTIVE

The objective of this study was to assess the impact on the obstetric outcomes of adding HCQ to classical treatments for women with refractory primary obstetric APS.

METHODS

In a retrospective single-centre cohort study, we compared pregnancy outcomes in women with refractory primary OAPS (2004-2019) who received two different treatments in subsequent pregnancies. Group A received 400 mg HCQ + 60 mg enoxaparin + LDA, while Group B received 60 mg enoxaparin + LDA. The main outcome was live birth rates, while pregnancy complications (early and late pregnancy losses and placental-mediated complications) were the secondary outcome.

RESULTS

A total of 101 pregnancies in 87 refractory primary OAPS patients were included. The rate of live-born babies in Group A (HCQ) was 97.1% (67/69) vs. 62.5% (20/32) in Group B (RR: 1.55 [95% CI, 1.19-2.1]; p < 0.001). Pregnancy complications in Group A were 8.7% (6/69) vs. 37.5% (12/32) in Group B (RR 0.22 [95% CI, 0.15-0.30]; p < 0.001).

CONCLUSION

Hydroxychloroquine was associated with a higher rate of live births and a lower prevalence of pregnancy complications in refractory primary obstetric APS. The addition of HCQ to classical treatment may present a promising approach that needs to be confirmed with prospective studies.

Commonly used immunosuppressive drugs for kidney diseases and pregnancy: focus on open questions

Pregnancy is still a challenge in women with autoimmune diseases or kidney transplantation. In this context, management of the immunosuppressive therapy is critical, but, in spite of more than 60 years of experience, many issues remain open, also because of the difficulty in disentangling, in complex patients, the effect of the disease and of the frequent multiple treatments. For this purpose, we have tried to synthesize the existing knowledge and the unresolved issues, to support counseling and promote patient empowerment.

Tough Choices: Exploring Medication Decision-Making During Pregnancy and Lactation Among Women With Inflammatory Arthritis

Objective

This study explored how women’s beliefs about drug safety and interactions with their health care providers influenced their decisions to continue arthritis medications during pregnancy and lactation.

Methods

We collaborated with ArthritisPower, a patient‐powered research network, and CreakyJoints, its partner online community, to develop and disseminate a survey among members with inflammatory arthritis who had at least one pregnancy after diagnosis. Participants’ free‐text responses were evaluated by using thematic analysis.

Results

Women in the sample were 40 years old on average (N = 66). Nineteen of their pregnancies had ended in fetal loss. Fifteen percent of all pregnancies were exposed to methotrexate. Among women who used safe arthritis medications, up to 80% discontinued treatment either in preparation for pregnancy or during pregnancy or lactation. Women’s decisions to continue medications during pregnancy were influenced by their perceptions of safety and advisement from health care providers, although they often described that advice about medication safety was inconsistent between providers.

Conclusion

Women often chose to endure active inflammatory arthritis rather than to use disease‐modifying antirheumatic drugs because of concerns about medication safety during pregnancy and lactation. Conflicting medical advice from health care providers undermined patients’ trust in their providers and in the safety of their medications. The high rate of peripartum exposure to methotrexate, a fetotoxic drug, underscores the need for better family planning care for women with childbearing potential.

COVID-19 Treatment: Drug Safety Prior to Conception and During Pregnancy and Breastfeeding

In December 2019, a new viral respiratory infection known as coronavirus disease 2019 (COVID-19) was first diagnosed in the city of Wuhan, China. COVID-19 quickly spread across the world, leading the World Health Organization to declare it a pandemic on March 11, 2020. The disease is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a similar virus to those involved in other epidemics such as severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). Epidemiological studies have shown that COVID-19 frequently affects young adults of reproductive age and that the elderly and patients with chronic disease have high mortality rates. Little is known about the impact of COVID-19 on pregnancy and breastfeeding. Most COVID-19 cases present with mild flu-like symptoms and only require treatment with symptomatic relief medications, whereas other cases with COVID-19 require treatment in an intensive care unit. There is currently no specific effective treatment for COVID-19. A large number of drugs are being used to fight infection by SARS-CoV-2. Experience with this therapeutic arsenal has been gained over the years in the treatment of other viral, autoimmune, parasitic, and bacterial diseases. Importantly, the search for an effective treatment for COVID-19 cannot expose pregnant women infected with SARS-CoV-2 to the potential teratogenic risks of these drugs. Therefore, it is necessary to determine and understand the safety of anti-COVID-19 therapies prior to conception and during pregnancy and breastfeeding.

An umbrella review of systematic reviews with meta-analyses evaluating positive and negative outcomes of Hydroxychloroquine and chloroquine therapy

BACKGROUND & AIMS

Hydroxychloroquine (HCQ) and chloroquine (CQ) are anti-malarial drugs frequently used in the rheumatologic field. They were recently identified as potential therapeutic options for Coronavirus Disease (COVID-19). The present study aims to map and grade the diverse health outcomes associated with HCQ/CQ using an umbrella review approach.

METHODS

Umbrella review of systematic reviews of observational and intervention studies. For observational studies, random-effects summary effect size, 95% confidence interval, and 95% prediction interval were estimated. We also assessed heterogeneity, evidence for small-study effect, and evidence for excess significance bias. The quality of evidence was then graded using validated criteria from highly convincing to weak. The evidence from randomized controlled trials (RCTs) was graded using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) tool.

RESULTS

From 313 articles returned in the literature search, six meta-analyses were included (n = 25 outcomes). Among meta-analyses (MAs) of observational studies, HCQ/CQ are weakly associated with a reduced risk for cardiovascular events and diabetes when used for autoimmune diseases and with spontaneous abortion; they are also associated with a higher risk of death in COVID-19 patients. Among MAs of RCTs, HCQ/CQ are associated with an improvement of articular manifestations of rheumatic diseases.

CONCLUSIONS

There is high evidence of the efficacy of HCQ/CQ in the rheumatologic field. The lack of evidence for efficacy and the risk of death associated with the use of HCQ/CQ for COVID-19 indicate the inappropriateness of their inclusion in recent COVID-19 therapy guidelines and the urgent need for RCTs to determine eventual appropriateness as a COVID-19 therapy.

Myasthenia gravis and pregnancy

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular junction that has higher incidence in younger women than men, which could be related to differences in sex hormones physiology and immune system functioning between males and females. MG can first present during pregnancy and variably affect pregnancy, labor, and postpartum period. In this paper, we had an updated overview on our understanding about MG presentation and its effect on pregnancy and vice versa, therapeutic options for MG pregnant women, management of pregnancy or labor complications in MG patients, and finally fetal and neonatal considerations in MG pregnant women. A multidisciplinary approach, involving obstetricians/gynecologists, neurologists, and anes-thesiologists, plays a pivotal role in improving the clinical outcomes in both MG mothers and their infants during pregnancy, delivery and postpartum.

Impact of hydroxychloroquine on the gestational outcomes of pregnant women with immune system problems that necessitate the use of the drug

AIM

To evaluate the impact of hydroxychloroquine (HCQ) on the perinatal outcomes of pregnancies with immune system disorders that necessitate the use of the drug.

METHODS

This cohort consisted of 202 pregnancies with poor obstetric history and immune system problems. Patients enrolled in special antenatal care program were administered low-dose low-molecular-weight heparin, low-dose salicylic acid and low-dose corticosteroid (prophylaxis protocol) as soon as their pregnancies were confirmed. Pregnancies with systemic lupus erythematosis, Sjogren syndrome and rheumatoid arthritis were additionally administered HCQ 200 mg daily as a part of their routine treatment. Pregnancies using HCQ were included in the study group (n = 39) while the remainders were included in control group (n = 163). We compared the groups in terms of the presence of miscarriage, fetal growth restriction (FGR), preeclampsia and preterm birth, as well as gestational week at birth, birthweight and "APGAR score of <7" at 10th minute.

RESULTS

Miscarriage rates were 28.2% and 28.2% while preterm birth rates were 16.6% and 28.2% in the control and study groups, respectively (P = 0.215). Preeclampsia and HCQ-related side effects were not detected in the groups. There were also no significant differences between the groups in terms of FGR, gestational day at birth, birthweight and the presence of "APGAR score <7" at 10th minute (P = 0.462, P = 0.064, P = 0.273 and P = 0.627, respectively).

CONCLUSION

Low-dose low-molecular-weight heparin, low-dose salicylic acid and low-dose corticosteroid prophylaxis together with HCQ seem to be promising in pregnancies with immune system disorders. HCQ seems to be a safe and effective drug in low dosages.

Hydroxychloroquine and Chloroquine in Prophylaxis and Treatment of COVID-19: What Is Known?

The corona virus disease-19 (COVID-19) pandemic has affected the entire world causing huge economic losses and considerable morbidity and mortality. Considering the explosive growth of the pandemic repurposing existing medicines may be cost-effective and may be approved for use in COVID-19 faster. Researchers and medical practitioners worldwide have explored the use of chloroquine and hydroxychloroquine, in few occasions combined with the macrolide antibiotic azithromycin, for COVID-19 treatment. These two drugs are economic and easily available, and hence gained attention as a potential option for COVID-19 management. As per the available evidence, the outcomes of treatments with these medications are conflicting from both the efficacy and safety (predominantly cardiac related) perspectives. Currently, multiple studies are underway to test the safety and efficacy of these medications and more results are expected in the near future. The retina, the endocrine system (with risk of hypoglycemia), the musculoskeletal system, the hematological system, and the neurological system may also be affected. The use of these drugs is contraindicated in patients with arrhythmias, known hypersensitivity, and in patients on amiodarone. In addition to the published literature, personal communication with doctors treating COVID-19 patients seems to suggest the drugs may be effective in reducing symptoms and hastening clinical recovery. The literature evidence is still equivocal and further results are awaited. There has been recent controversy including retraction of articles published in prestigious journals about these medicines. Their low cost, long history of use, and easy availability are positive factors with regard to use of these drugs in COVID-19.

Treatment of Autoimmune Bullous Diseases During Pregnancy and Lactation: A Review Focusing on Pemphigus and Pemphigoid Gestationis

Pregnancy may induce the onset or exacerbation of autoimmune bullous diseases such as pemphigus or pemphigoid gestationis. A shift toward T helper (Th) 2 immune response and the influence of hormonal changes have been evoked as possible triggering factors. Therapeutic management of this setting of patients may represent a challenge, mainly due to safety concerns of some immunosuppressive drugs during pregnancy and lactation. In this narrative review, we provided a comprehensive overview of the therapeutic management of autoimmune bullous diseases in pregnant and breastfeeding women, focusing on pemphigus and pemphigoid gestationis.

Therapeutic options in the treatment of severe acute respiratory syndrome coronavirus 2 in pregnant patient

The severe acute respiratory syndrome coronavirus 2 pandemic has resulted in the development of various therapeutics to treat and prevent major complications related to the virus; pregnant patients are vulnerable to acquiring severe acute respiratory syndrome coronavirus 2 because of frequent contact with the healthcare setting. Despite the publication of a plethora of case series and randomized control trials of severe acute respiratory syndrome coronavirus 2 therapeutics, few have addressed treatment in the pregnant population. To date, there has been no published review of therapeutic options in the treatment of pregnant patients with severe acute respiratory syndrome coronavirus 2 infection. Here, we provide a review of available treatments for severe acute respiratory syndrome coronavirus 2, various trials with inclusion and exclusion of the pregnant patients, and potential side effects of each treatment in the pregnant patient.
