Antirheumatic Drugs in Pregnancy and Lactation

Pregnancy Outcomes in Women With Rheumatoid Arthritis: A Systematic Review and Meta-analysis

ABSTRACT

Rheumatoid arthritis (RA) is a chronic inflammatory rheumatic disease affecting multiple joints and can also be a systemic widespread, affecting major organs. Rheumatoid arthritis is associated with greater adverse maternal and neonatal outcomes in comparison to the general obstetric population. This systematic review and meta-analysis aims to investigate the pregnancy outcomes in RA patients in comparison to the general pregnant population.Nine studies involving 11,999 RA patients met the eligibility criteria with 9,921,808 controls. Rheumatoid arthritis patients were compared with their control counterparts according to random-effects model statistical analysis.We searched databases from inception to September 8, 2021. Eligible studies reported maternal outcomes (preeclampsia, cesarean delivery, and preterm delivery) and/or neonatal outcomes. Data were pooled across using random-effects model. Subgroup analysis was conducted on RA patients alone. The review was registered prospectively with PROSPERO (CRD42021250521).In terms of maternal outcomes, there was an increased rate of cesarean delivery (odds ratio [OR], 1.55), preeclampsia (OR, 1.61), and preterm delivery (OR, 1.83) in RA patients compared with their control counterparts. In terms of neonatal outcomes, a higher rate of lower gestational weight (mean difference [MD], -0.19 kg), requirement for neonate intensive care unit admission (OR, 1.34), and stillbirths (OR, 1.99) were observed in RA patients compared with the controls. A subgroup analysis of 4 studies involving only RA patients (n = 3761) was conducted. A total of 33.2% of patients had a cesarean delivery, 7.3% had preeclampsia, 14.8% had a preterm delivery, and 9.5% of neonates had low birth weight.Compared with the general pregnant population, women with RA tend to have a higher risk of maternal and neonatal complications. As a result, this study hopes to increase awareness into the importance of counseling and managing RA patients.

Pregnancy and the eye

PURPOSE OF REVIEW

The aim of this study was to summarize common eye changes that may occur during pregnancy, and how pregnancy may affect preexisting eye conditions such as glaucoma and diabetic retinopathy. Challenges and complexities surrounding the treatment of these eye conditions during pregnancy are also highlighted.

RECENT FINDINGS

Refractive changes are common and may persist in the postpartum in patients with keratoconus. Although new medical and surgical glaucoma treatments are available, their safety in pregnancy is unknown. Limited use of topical and systemic glaucoma therapies is recommended, with a preference for selective laser trabeculoplasty as first line treatment in appropriate cases. The impact of pregnancy on diabetic retinopathy remains unclear. Although anti-vascular endothelial growth factor agents are first-line treatment for sight-threatening diabetic retinopathy, their effect on the developing foetus remains unknown and are therefore best avoided in the first and second trimesters. Noninfectious uveitis tends to become less active during pregnancy, allowing the potential tapering of systemic therapy and the use of local topical or injected corticosteroid treatment for active disease as required.

SUMMARY

Significant changes can occur to the eye during pregnancy, wherein the optimal treatment for many ocular conditions remains uncertain, highlighting the need for further research to develop clear recommendations that best balance the need to preserve the mother's sight, and the health of the developing foetus. The need for preconception planning, and collaborative multidisciplinary care between the obstetrician, physician, ophthalmologist and paediatrician is paramount.

Management of acute and recurrent pericarditis in pregnancy

This review summarizes the currently available evidence on the management of acute and recurrent pericarditis during pregnancy, focusing on the safety of diagnostic procedures and treatment options for the mother and foetus. Family planning should be addressed in women with recurrent pericarditis of reproductive age and adjustment of therapy should be considered before a planned pregnancy. The treatment of pericarditis in pregnancy is similar to that for non-pregnant women but considers current knowledge on drug safety during pregnancy and lactation. The largest case series on this topic described 21 pregnancies with idiopathic recurrent pericarditis. Pregnancy should be planned in a phase of disease quiescence. Non-steroidal anti-inflammatory drugs can be used at high dosages until the 20th week of gestation (except low-dose aspirin 100 mg/die). Colchicine is allowed until gravindex positivity; after this period, administration of this drug during pregnancy and lactation should be discussed with the mother if its use is important to control recurrent pericarditis. Prednisone is safe if used at low-medium doses (2,5 - 10 mg/die). General outcomes of pregnancy in patients with pericarditis are good when the mothers are followed by a multidisciplinary team with experience in the field.

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.

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.

Rheumatologic Medication Use During Pregnancy

Chronic rheumatic diseases often occur in women of reproductive age, and the effect rheumatic disease has on pregnancy varies depending on the condition. Medical management of rheumatic diseases during pregnancy may prevent joint or organ damage and minimize the adverse effects of the disease itself on pregnancy outcomes. Each patient requires individual assessment to control disease activity while minimizing or avoiding medications with potential maternal or fetal toxicity. An open discussion with shared decision making between patients, obstetricians, rheumatologists, and pharmacists is imperative to create an individualized treatment plan that meets patients' goals. This article will review the current literature for use of disease modifying antirheumatic drugs and biologics during pregnancy and lactation, providing health care professionals with the most up-to-date information available.

Management of autoimmune blistering diseases in pregnancy and the neonate

The management of autoimmune blistering diseases (AIBD) is therapeutically challenging, particularly in patients who plan to conceive, or are pregnant or breastfeeding. Not only is a patient's immune system altered by pregnancy-associated hormonal changes, but several medications used for AIBD treatment are not recommended for use in pregnancy or lactation. The data acquired regarding the safety and efficacy of these therapeutic interventions are gathered from studies or case reports from other diseases, as the treatment modalities are similar and randomized controlled trials are typically not performed in the setting of pregnancy. Although some medications for AIBD treatment are considered unsafe for use in pregnancy, many effective and tolerable therapies are able to provide benefit to these patients. In fact, most first-line agents may be used in pregnancy, to a given extent. This article discusses the medications used to treat AIBD prior to conception, during pregnancy, and while breastfeeding, as well as highlights those that are contraindicated. The preferred approach to management in these patients is also discussed. Additionally, we present the available information regarding neonates of mothers with a diagnosis of AIBD, including the likelihood, identification, and management of neonatal blistering and the effects from medication exposure in utero.

Efficacy of methotrexate as anti-inflammatory and anti-proliferative drug in dermatology: Three case reports

Methotrexate (MTX) is a folic acid analog with anti-proliferative (anti-neoplastic, cytotoxic), immunosuppressive and anti-inflammatory properties, which has been used in the treatment of various cutaneous disorders, such as psoriasis, keratoacanthoma, pityriasis rubra pilaris, atopic dermatitis, mycosis fungoides, bullous skin diseases, systemic sclerosis, morphea, lupus erythematosus, dermatomyositis and crusted scabies. Inhibition of cell proliferation is explained through its role in blocking DNA/RNA synthesis, by inhibiting dihydrofolate reductase, necessary for the production of pyrimidine and purine nucleotides. An anticancer effect can be related to α-oxoaldehyde metabolism (MTX increases methylglyoxal levels). Its anti-inflammatory property is based on the inhibition of 5-aminoimidazole-4-carboxamide ribonucleotide transformylase, thus increasing intracellular and extracellular adenosine, a purine nucleoside with anti-inflammatory effect. This drug can limit inflammation by scavenging free radicals and decreasing malondialdehyde-acetaldehyde protein-adduct production. Moreover, the anti-proliferative and anti-inflammatory effects can also be related to inhibition of the DNA methylation pathway, thus inhibiting methionine formation. The aim of the present study was to report various dermatological cases from our daily practice that demonstrate the efficacy of MTX in the treatment of cutaneous diseases, highlighting different mechanisms of action: its anti-inflammatory effect in psoriasis and its anti-proliferative, and anti-neoplastic effect in well-differentiated squamous cell carcinoma or in keratoacanthoma. Moreover, different administration pathways and doses are addressed. Assessment of the treatment plan, clinical improvement of cutaneous lesions, biologic evaluation, final aesthetic result, quality of life, as well as potential adverse effects and drug tolerance related to each case mentioned.

Systemic medications used in treatment of common dermatological conditions: safety profile with respect to pregnancy, breast feeding and content in seminal fluid

Prescribing for pregnant or lactating patients and male patients wishing to father children can be a difficult area for dermatologists. There is a lack of review articles of commonly used systemic medications in dermatology with respect to their effects on developing embryogenesis and their potential transfer across the placenta, in breast milk and in seminal fluid. This paper aims to provide an up to date summary of evidence to better equip dermatologists to inform patients about the effects of systemic medications commonly used in dermatology to treat conditions such as atopic dermatitis, psoriasis and acne, on current and future embryogenesis and fertility.

Treatment of Autoimmune Bullous Disorders in Pregnancy

Autoimmune bullous diseases (AIBD), including pemphigus, bullous pemphigoid, epidermolysis bullosa acquisita, mucous membrane pemphigoid, and pemphigoid gestationis, pose significant therapeutic challenges, especially in pregnant and post-partum breastfeeding patients or those planning to conceive. Data on the safety and efficacy of therapeutic interventions during the perinatal period are lacking because randomized controlled trials are typically not performed in this setting. However, many of the treatments for AIBD are also used in other diseases, so data can be extrapolated from studies or case reports in these other patient populations. It appears that many of the treatments for AIBD can adversely affect the fetus or neonate, and alterations in immune status caused by pregnancy-associated hormonal changes can negatively impact disease control. This article summarizes and weighs the risks and benefits of the various agents used to treat AIBD during pregnancy. We also present the available information on lactation as well as effects on male fertility.

A clinical decision support system for prediction of pregnancy outcome in pregnant women with systemic lupus erythematosus

OBJECTIVE

Pregnancy among systemic lupus erythematosus (SLE)-affected women is highly associated with poor obstetric outcomes. Predicting the risk of foetal outcome is essential for maximizing the success of pregnancy. This study aimed to develop a clinical decision support system (CDSS) to predict pregnancy outcomes among SLE-affected pregnant women.

METHODS

We performed a retrospective analysis of 149 pregnant women with SLE, who were followed at Shariati Hospital (104 pregnancies) and a specialized clinic (45 pregnancies) from 1982 to 2014. We selected significant features (p<0.10) using a binary logistic regression model performed in IBM SPSS (version 20). Afterward, we trained several artificial neural networks (multi-layer perceptron [MLP] and radial basis function [RBF]) to predict the pregnancy outcome. In order to evaluate and select the most effective network, we used the confusion matrix and the receiver operating characteristic (ROC) curve. We finally developed a CDSS based on the most accurate network. MATLAB 2013b software was applied to design the neural networks and develop the CDSS.

RESULTS

Initially, 45 potential variables were analysed by the binary logistic regression and 16 effective features were selected as the inputs of neural networks (P-value<0.1). The accuracy (90.9%), sensitivity (80.0%), and specificity (94.1%) of the test data for the MLP network were achieved. These measures for the RBF network were 71.4%, 53.3%, and 79.4%, respectively. Having applied a 10-fold cross-validation method, the accuracy for the networks showed 75.16% accuracy for RBF and 90.6% accuracy for MLP. Therefore, the MLP network was selected as the most accurate network for prediction of pregnancy outcome.

CONCLUSION

The developed CDSS based on the MLP network can help physicians to predict pregnancy outcomes in women with SLE.

The role of synthetic drugs in the biologic era: therapeutic strategies for treating juvenile idiopathic arthritis

INTRODUCTION

Juvenile idiopathic arthritis is the most frequent chronic rheumatic disease in childhood. Synthetic disease modifying drugs (DMARDs) have been used in its treatment since the 1980s and have led to substantial improvement of quality of life and disease outcome. Recent pharmacological research has focused on newer medications, especially biologic agents.

AREAS COVERED

Synthetic DMARDS, especially methotrexate, rightfully remain the first-line treatment of most categories of juvenile arthritis, as attested by several international guidelines. A substantial body of evidence supports these medications, and recent research tries to clarify their optimal use in the clinical setting, both as monotherapy and in combination with biologics. In addition, new forms of synthetic DMARDs are in the research pipeline, or are already used for rheumatoid arthritis.

EXPERT OPINION

Methotrexate remains the preferred first-line medication for polyarticular arthritis, with leflunomide as a viable alternative in case of intolerance or toxicity, despite lack of approval in Europe and the US. Sulfasalazine and hydroxychloroquine are used only rarely in clinical practice, considered in combination with methotrexate if biologics are not available. New synthetic DMARDS are in the research pipeline for JIA, in the form of small molecules.

The value of glucocorticoid co-therapy in different rheumatic diseases--positive and adverse effects

Glucocorticoids play a pivotal role in the management of many inflammatory rheumatic diseases. The therapeutic effects range from pain relief in arthritides, to disease-modifying effects in early rheumatoid arthritis, and to strong immunosuppressive actions in vasculitides and systemic lupus erythematosus. There are multiple indications that adverse effects are more frequent with the longer use of glucocorticoids and use of higher dosages, but high-quality data on the occurrence of adverse effects are scarce especially for dosages above 10 mg prednisone daily. The underlying rheumatic disease, disease activity, risk factors and individual responsiveness of the patient should guide treatment decisions. Monitoring for adverse effects should also be tailored to the patient. Continuously balancing the benefits and risks of glucocorticoid therapy is recommended. There is an ongoing quest for new drugs with glucocorticoid actions without the potential to cause harmful effects, such as selective glucocorticoid receptor agonists, but the application of a new compound in clinical practice will probably not occur within the next few years. In the meantime, basic research on glucocorticoid effects and detailed reports on therapeutic efficacy and occurrence of adverse effects will be valuable in weighing benefits and risks in clinical practice.

Use of DMARDs and biologics during pregnancy and lactation in rheumatoid arthritis: what the rheumatologist needs to know

Rheumatoid arthritis (RA), a chronic autoimmune inflammatory disease of synovial joints, can lead to chronic pain and structural joint damage, as well as other organ involvement, especially if not adequately controlled. Because it can affect women in their reproductive years, care of pregnant women with RA requires a delicate balance of maintaining disease control while limiting potential toxicity to the fetus and neonate. While most women experience a substantial improvement in disease activity during pregnancy, for some women their RA remains active. It can even manifest itself for the first time during pregnancy or early in the post-partum period. Optimizing disease control prior to conception is key, but utilizing disease-modifying treatments effectively and safely throughout pregnancy and lactation requires open dialogue and shared decision making. This review provides evidence-based recommendations for use of disease-modifying antirheumatic drugs (DMARDs) and biologic response modifiers to guide rheumatologists in their care of pregnant and lactating women with RA and serves as a guide to counsel male patients with RA on family planning decisions.

Treatment of atopic dermatitis in pregnancy

Atopic dermatitis (AD), also referred to as eczema, is one of the most frequently observed skin diseases in pregnant patients. The presentation and histopathology of this condition during pregnancy is identical to that of the non-pregnant individual. AD is a T-helper 2 dominant disease and may worsen during pregnancy, which favors this population of T-lymphocytes. AD management during pregnancy requires special precautions to avoid harming the fetus. Herein is an exploration of the different options available for the treatment of the pregnant patient with AD. The management of concomitant bacterial and viral infections is also discussed.

Uveitis and gender: the course of uveitis in pregnancy

The hormonal and immunological changes in pregnancy have a key role in maintaining maternal tolerance of the semiallogeneic foetus. These pregnancy-associated changes may also influence the course of maternal autoimmune diseases. Noninfectious uveitis tends to improve during pregnancy. Specifically, uveitis activity tends to ameliorate from the second trimester onwards, with the third trimester being associated with the lowest disease activity. The mechanism behind this phenomenon is likely to be multifactorial and complex. Possible mechanisms include Th1/Th2 immunomodulation, regulatory T-cell phenotype plasticity, and immunosuppressive cytokines. This clearly has management implications for patients with chronic sight threatening disease requiring systemic treatment, as most medications are not recommended during pregnancy due to lack of safety data or proven teratogenicity. Given that uveitis activity is expected to decrease in pregnancy, systemic immunosuppressants could be tapered during pregnancy in these patients, with flare-ups being managed with local corticosteroids till delivery. In the postpartum period, as uveitis activity is expected to rebound, patients should be reviewed closely and systemic medications recommenced, depending on uveitis activity and the patient's breastfeeding status. This review highlights the current understanding of the course of uveitis in pregnancy and its management to help guide clinicians in managing their uveitis patients during this special time in life.

Nonsteroidal anti-inflammatory drugs during pregnancy and the initiation of lactation

Nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin, which are available as "over-the counter" medications in most countries, are widely used by both pregnant and lactating women. They are popular non-opioid analgesics for the treatment of pain after vaginal and operative delivery. In addition, NSAIDs are used for tocolysis in premature labor, and low-dose aspirin has a role in the prevention of preeclampsia and recurrent miscarriage in antiphospholipid syndrome. NSAIDs and aspirin may affect fertility and increase the risk of early pregnancy loss. In the second trimester their use is considered reasonably safe, but has been associated with fetal cryptorchism. In the third trimester, NSAIDs and aspirin are usually avoided because of significant fetal risks such as renal injury, oligohydramnios, constriction of the ductus arteriosus (with potential for persistent pulmonary hypertension in the newborn), necrotizing enterocolitis, and intracranial hemorrhage. Maternal administration or ingestion of most NSAIDs results in low infant exposure via breastmilk, such that both cyclooxygenase-1 and cyclooxygenase-2 inhibitors are generally considered safe, and preferable to aspirin, when breastfeeding.

Lateral rectus myositis mimicking an abducens nerve palsy in a pregnant woman

Myositis is a rare unknown inflammatory disorder of the skeletal muscle tissue. Generalized inflammatory myopathies, polymyositis, and dermatomyositis have been reported during pregnancy. Isolated orbital myositis in pregnancy has not been previously described in the literature. The authors report a case of left isolated orbital myositis in a primigravida at 38 weeks gestation affecting the patient's left lateral rectus muscle. MRI of the orbit was consistent with the diagnosis. She showed remarkable clinical improvement with oral corticosteroids therapy.

Do you need to definitively diagnose the location of a pregnancy of unknown location? The case for "yes"

Pregnancy of unknown location (PUL) is a common diagnostic challenge. The primary diagnostic goal is to ensure that the PUL is nonviable prior to proceeding with any invasive procedures. In nonviable PUL, there are several diagnostic and treatment strategies, which are generally quite safe. However, the management option that provides the most definite diagnosis is uterine curettage. We advocate use of uterine curettage in all cases of nonviable PUL because it limits exposure to a chemotherapeutic agent to only those who need it and it allows for the most accurate information for counseling the patient on prognosis of future pregnancies.

Lactation and neonatal nutrition: defining and refining the critical questions

This paper resulted from a conference entitled "Lactation and Milk: Defining and refining the critical questions" held at the University of Colorado School of Medicine from January 18-20, 2012. The mission of the conference was to identify unresolved questions and set future goals for research into human milk composition, mammary development and lactation. We first outline the unanswered questions regarding the composition of human milk (Section I) and the mechanisms by which milk components affect neonatal development, growth and health and recommend models for future research. Emerging questions about how milk components affect cognitive development and behavioral phenotype of the offspring are presented in Section II. In Section III we outline the important unanswered questions about regulation of mammary gland development, the heritability of defects, the effects of maternal nutrition, disease, metabolic status, and therapeutic drugs upon the subsequent lactation. Questions surrounding breastfeeding practice are also highlighted. In Section IV we describe the specific nutritional challenges faced by three different populations, namely preterm infants, infants born to obese mothers who may or may not have gestational diabetes, and infants born to undernourished mothers. The recognition that multidisciplinary training is critical to advancing the field led us to formulate specific training recommendations in Section V. Our recommendations for research emphasis are summarized in Section VI. In sum, we present a roadmap for multidisciplinary research into all aspects of human lactation, milk and its role in infant nutrition for the next decade and beyond.

Rheumatoid arthritis and pregnancy: evolution of disease activity and pathophysiological considerations for drug use

It has long been known that pregnancy and childbirth have a profound effect on the disease activity of rheumatic diseases. For clinicians, the management of patients with RA wishing to become pregnant involves the challenge of keeping disease activity under control and adequately adapting drug therapy during pregnancy and post-partum. This article aims to summarize the current evidence on the evolution of RA disease activity during and after pregnancy and the use of anti-rheumatic drugs around this period. Of recent interest is the potential use of anti-TNF compounds in the preconception period and during pregnancy. Accumulating experience with anti-TNF therapy in other immune-mediated inflammatory diseases, such as Crohn's disease, provides useful insights for the use of TNF blockade in pregnant women with RA, or RA patients wishing to become pregnant.

Nonmalignant diseases and treatments associated with primary ovarian failure: an expanded role for fertility preservation

Cancer treatments can be detrimental to fertility; recent literature has focused on the efforts of fertility preservation for this patient population. It should be recognized, however, that several nonmalignant medical conditions and therapeutic interventions could be similarly hazardous to fertility. Some of these nonmalignant diseases and their treatments that can adversely impact the reproductive axis are gastrointestinal diseases, rheumatologic disorders, nonmalignant hematologic conditions, neurologic disorders, renal disorders, gynecologic conditions, and metabolic diseases. Their negative effects on reproductive function are only now being appreciated and include impaired ovarian function, endocrine function, or sexual function and inability to carry a pregnancy to term. Complications and comorbidities associated with certain diseases may limit the success of established fertility preservation options. Recent advances in fertility preservation techniques may provide these patients with new options for childbearing. Here, we review several fertility-threatening conditions and treatments, describe current established and experimental fertility preservation options, and present three initiatives that may help minimize the adverse reproductive effects of these medical conditions and treatments by raising awareness of the issues and options: (1) increase awareness among practitioners about the reproductive consequences of specific diseases and treatments, (2) facilitate referral of patients to fertility-sparing or restorative programs, and (3) provide patient education about the risk of infertility at the time of diagnosis before initiation of treatment.

Rituximab for management of refractory pregnancy-associated immune thrombocytopenic purpura

BACKGROUND

Rituximab is a novel therapy for immune thrombocytopenic purpura (ITP); however, information about its safety in pregnancy is limited. This case illustrates the successful use of rituximab to treat pregnancy-associated ITP.

CASE

A 34-year-old woman presented with severe ITP at 23 weeks' gestation. Standard treatment with corticosteroids, intravenous immune globulin, and splenectomy failed to raise the platelet count. Due to ongoing bleeding, rituximab was given in the 26th week of pregnancy. The platelet count rose to over 100 × 10(9)/L after four weeks. The neonatal B-lymphocyte count normalized at four months after delivery. There were no neonatal complications of rituximab therapy.

CONCLUSION

Rituximab may be safe for use in treating pregnancy-associated ITP. This case highlights the need to investigate further the safety and efficacy of rituximab in pregnancy.

Infiltrative lung diseases in pregnancy

Pregnancy may affect the diagnosis, management, and outcome of infiltrative lung disease (ILD). Conversely, ILD may affect pregnancy. ILD may occur as a result of drugs administered commonly or specifically during pregnancy. Most ILDs predominate in patients older than 40 years and are thus rare in pregnant women. During pregnancy ILD may arise de novo and preexisting ILD may be exacerbated or significantly worsened. Some ILDs generally do not alter the management of pregnancy, labor, or delivery. Preexisting ILD no longer contraindicates pregnancy systematically, but thorough evaluation of ILD before pregnancy is required to identify potential contraindications and adapt monitoring.

Hydroxychloroquine in systemic lupus erythematosus and rheumatoid arthritis and its safety in pregnancy

INTRODUCTION

The antimalarial drug hydroxychloroquine (HCQ) is widely used to treat various rheumatic diseases. Many autoimmune diseases occur in women of child-bearing age who may become pregnant while on therapy, which raises concerns regarding the teratogenicity of HCQ and its effect on the outcome of the pregnancy. There is a lack of data regarding the safety of HCQ during pregnancy.

AREAS COVERED

In this review, the authors attempt to identify relevant publications by searching MEDLINE, Cochrane database, Ovid-Currents Clinical Medicine, Ovid-Embase:Drugs and Pharmacology, EBSCO, Web of Science and SCOPUS using the search terms HCQ and/or pregnancy. A basis for the mechanism of action of HCQ is provided.

EXPERT OPINION

HCQ has been shown by numerous studies over the past 15 years to be efficacious in the treatment of autoimmune diseases, including systemic lupus erythematosus, discoid lupus erythematosus and rheumatoid arthritis. HCQ does not appear to be associated with any increased risk of congenital defects, spontaneous abortions, fetal death, prematurity or decreased numbers of live births in patients with autoimmune diseases. Therefore, in the author's opinion, HCQ is safe for the treatment of autoimmune diseases during pregnancy.

Pemphigus vulgaris in pregnancy: analysis of current data on the management and outcomes

OBJECTIVES

The occurrence of pemphigus vulgaris (PV) during pregnancy is rare. The purpose of this review was to describe management of PV in the mother, and report maternal and perinatal outcomes associated with the disease.

DATA SOURCES

A search of PubMed was conducted using the phrases "pemphigus and pregnancy" and "neonatal pemphigus." The bibliographies of retrieved articles were also searched for relevant reports. Only articles in English and in which the diagnosis of pemphigus had been made on the basis of histology or immunopathology were included.

TABULATION, INTEGRATION, AND RESULTS

In 38 reports, pregnancies from 49 women with PV were described. Among the 40 patients in whom clinical profiles were provided, 33 had active disease and 7 were disease free. Prednisone was used in 37 of 49 (75%) patients with doses ranging from 5 to 300 mg/day (mean 152.5 mg). Concomitant therapies included plasmapheresis, plasma exchange, and dapsone in 1 patient each, and azathioprine in 5. Of the 44 live births, 20 (45%) neonates had PV lesions at birth and 24 (55%) were lesion-free. Five stillbirths were reported. In all neonates, PV lesions resolved within 1 to 4 weeks, either spontaneously or with mild topical corticosteroids treatment. Of the 5 intrauterine deaths, 1 was due to umbilical cord prolapse, 1 attributed to placental dysfunction, and 1 to cytomegalovirus pneumonitis. In the remaining 2, the cause was unknown. One neonate died 2 days after delivery due to meconium aspiration syndrome. Thus the aggregate perinatal mortality rate was 12% (6/49).

CONCLUSIONS

The outcome of pregnancies complicated by pemphigus is generally good, but achieving good outcomes likely depends on the collaborative efforts of the dermatologist and obstetrician. The available data suggest that the rate of perinatal mortality is increased, but these data may be subject to publication bias.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians.

LEARNING OBJECTIVES

After completion of this educational activity, the participant should be better able to describe appropriate medical therapies for pemphigus vulgaris complicating pregnancy, and plan the management of pregnancies complicated by pemphigus vulgaris.

Systematic review of hydroxychloroquine use in pregnant patients with autoimmune diseases

OBJECTIVE

The purpose of this study is to compare the incidence of congenital defects, spontaneous abortions, number of live births, fetal death and pre-maturity in women with autoimmune diseases taking HCQ during pregnancy.

METHODS

The authors searched MEDLINE, Cochrane data base, Ovid-Currents Clinical Medicine, Ovid-Embase:Drugs and Pharmacology, EBSCO, Web of Science, and SCOPUS using the search terms HCQ and/or pregnancy. We attempted to identify all clinical trials from 1980 to 2007 regardless of language or publication status. We also searched Cochrane Central Library and http://www.Clinical trials.gov for clinical trials of HCQ and pregnancy. Data were extracted onto standardized forms and were confirmed.

RESULTS

The odds ratio (OR) of congenital defects in live births of women taking HCQ during pregnancy was 0.66, 95% confidence intervals (CI) 0.25, 1.75. The OR of a live birth for women taking HCQ during pregnancy was 1.05 (95% CI 0.58, 1.93). The OR of spontaneous abortion in women taking HCQ during pregnancy was 0.92 (95% CI 0.49, 1.72). The OR of fetal deaths in women taking HCQ during pregnancy was 0.97 (95% CI 0.14, 6.54). The OR of pre-mature birth defined as birth before 37 weeks in women taking HCQ during pregnancy was 1.10 (95% CI 0.75, 1.61).

CONCLUSION

HCQ is not associated with any increased risk of congenital defects, spontaneous abortions, fetal death, pre-maturity and decreased numbers of live births in patients with auto-immune diseases.

Inflammatory bowel disease and pregnancy: evidence, uncertainty and patient decision-making

Inflammatory bowel disease (IBD) often affects women during their child-bearing years. Management of a pregnant IBD patient, or a patient contemplating pregnancy, poses unique challenges and can be quite daunting. Knowledge of the basic interplay among disease, normal host physiology and pregnancy is vital to managing these patients. One of the most important advances in the management of IBD over the past decade has been the finding that normal pregnancy outcomes can be achieved when a woman enters the pregnancy in remission. New insights into the safety of a wider spectrum of drugs in these patients has allowed for increased success in IBD management. The evidence supporting medical interventions including biological therapy such as antibodies to tumour necrosis factor agents is reviewed. Once the treating physician understands this complex relationship, management of the pregnant IBD patient can often become a rewarding experience.
