Disease specific problems related to drug therapy in pregnancy

Racial disparities in pregnancy outcomes among women with rheumatic diseases: A systematic literature review

OBJECTIVE

There is a limited understanding of racial disparities in adverse pregnancy outcomes (APO) among women with rheumatic diseases. The aim of our study was to conduct a systematic literature review to evaluate the impact of race on APO in women with rheumatic diseases.

METHODS

Databases were searched to find reports of APO stratified by race among women with rheumatic diseases. The initial searches were conducted in July 2020 and updated in March 2021. Of the final included articles, the full text was reviewed, and data was extracted from each study using a standard data abstraction form.

RESULTS

Ten studies with a total of 39,720 patients met our eligibility criteria. There was a greater propensity for APO in racial minorities with rheumatic diseases compared to their White counterparts. Among women with systemic lupus erythematosus (SLE), Black women had the highest odds of APOs, particularly those with a concomitant diagnosis of antiphospholipid syndrome. Pooled meta-analysis could not be done due to multiple factors, including heterogeneity between studies.

CONCLUSION

Racial minorities with rheumatic diseases are more prone to APO compared to their White counterparts. One limitation is the lack of standardized criteria for APO, which prohibited direct comparison between studies. There is also a paucity of data looking at APOs among women with rheumatic diseases other than SLE. Further research is needed to explore the drivers of these racial disparities to guide targeted solutions for those in the greatest need.

Uterine transplant: an ethical framework analysis from a Middle Eastern perspective

BACKGROUND

Significant advances in infertility treatment have been achieved over the past several decades, but women with uterine dysfunction, anomaly, or agenesis still need support to carry a pregnancy to term. Recently, advancements in surgical, anesthetic and immunosuppressive therapy have brought the idea of successful uterine transplant closer to reality, but many challenges must be overcome before uterine transplant can become more common, including ethical challenges related to the study and the conduct of this procedure.

METHODS

This was an updated ethical analysis of uterine transplant from a Middle Eastern perspective, using an established ethical framework that has been adapted for the analysis of research in non-Western cultures and developing countries.

RESULTS

Using the ethical framework, this analysis explored research developments in uterine transplant to date, using the following categories: collaborative partnership, social value, scientific validity, a fair selection of study population, favorable risk-benefit ratio, independent review, informed consent, and respect for recruited participants. The analysis revealed a significant need for region- and religion-specific ethical guidelines for uterine transplant procedures.

CONCLUSIONS

The horizons of research need to expand by addressing and researching the ethical issues related to uterine transplant trials and clinical procedures.

LIMITATIONS

Limitations included the challenges related to applying ethical analyses to work in developing countries, and the fact that this analysis was based on the views and interpretations of a single researcher.

Assessment of the correlation between various risk factors and orofacial cleft disorder spectrum: a retrospective case-control study

Background

Orofacial clefts (OFCs) comprise a wide range of malformations, including cleft lip, cleft palate, and cleft lip with cleft palate, which can vary in terms of etiology, severity, and disease burden.

Objective(s)

This study aimed to evaluate the correlation between various risk factors and orofacial cleft disorder spectrum in newborns.

Study design

A total of 323 cases and 400 controls were enrolled in this study and evaluated in terms of the maternal history of abortion or miscarriage, child’s sex, maternal and paternal age, maternal history of systemic disease, history of medication therapy during pregnancy, birth order, consanguineous marriage, and complications during pregnancy.

Results

Analysis of the results suggested that consanguineous marriage, a maternal history of abortion/miscarriage, and complications during pregnancy could potentially increase the risk of OFCs in children (P < 0.05). However, the analyses revealed that the other variables could not potentially increase the risk of OFCs (P > 0.05).

Conclusion(s)

Multiple cofactors may simultaneously contribute to the formation of such abnormalities; therefore, a comprehensive, multidisciplinary care program is necessary to ensure a successful pregnancy period and the birth of a healthy newborn.

Safety issues and recommendations for successful pregnancy outcome in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) primarily affects women of childbearing age. One of the major changes in SLE focuses on the timing of a successful pregnancy. In the past, pregnancy was strongly discouraged in SLE, especially in the presence of risk factors such as nephritis, use of immunosuppressive therapies, or positivity of specific autoantibodies such as anti-phospholipids and anti-Ro/SSA, La/SSBA. Thanks to our better knowledge on the disease and management, pregnancy success rates in SLE patients have significantly improved care by the a multidisciplinary team which fosters a successful pregnancy with minimal complications for the mother and fetus when the disease is inactive or in remission. This approach is based on a counseling phase before pregnancy, to assess SLE activity phase, specific medications, risk factors, and continues through pregnancy and lactation with significantly improved pregnancy outcomes. Further, we can now better define the risk of disease flares during pregnancy based on a better understanding of the changes in maternal immunity and its relationship with SLE-associated autoimmunity and chronic inflammation. There is wide consensus that women with SLE can have successful pregnancies as long as conception is planned in a phase of inactive disease, and when the patient is closely managed by a rheumatologist, high-risk OB/GYN, neonatologist, and other medical specialists as indicated. Preconception counseling is essential to assess the risk of both fetal and maternal complications as well as identify life-threatening contraindications. Particular attention should be used in those SLE cases that have nephritis, APS or positivity for aPL, pulmonary hypertension, and positive anti-Ro/SSA or anti-La/SSB antibodies. In conclusion, the use of specific guidelines on the management of SLE before and during pregnancy and lactation, and a better understanding of the use of immunosuppressive therapies have significantly increased pregnancy success.

Leflunomide use during pregnancy and the risk of adverse pregnancy outcomes

Objectives

Leflunomide is known to be embryotoxic and teratogenic in rodents. However, there is less evidence in humans. We quantified the risk of major congenital malformation (MCM), prematurity, low birth weight (LBW) and spontaneous abortion associated with leflunomide exposure during pregnancy in humans.

Methods

From a cohort of 289 688 pregnancies in Montreal, Quebec, Canada, from 1998 to 2015, first-trimester leflunomide exposure and other antirheumatic drug exposures were studied for their association with MCM and spontaneous abortions. Also second or third-trimester leflunomide exposures were examined for associations with prematurity and LBW. Logistic regression model-based generalised estimating equations were used.

Results

51 pregnancies were exposed to leflunomide during the first trimester, and 21 during the second/third trimesters. Adjusting for potential confounders, use of leflunomide during the first trimester of pregnancy was not associated with the risk of MCM (adjusted OR (aOR) 0.97, 95% CI 0.81 to 1.16; 5 exposed cases). No association was found between second/third-trimester exposure to leflunomide and the risk of prematurity (aOR 4.03, 95% CI 0.91 to 17.85; 7 exposed cases) nor LBW (aOR 1.06, 95%CI 0.90 to 1.25; 8 exposed cases). Pregnancy exposure to leflunomide was also not associated with the risk of spontaneous abortion (aOR 1.09, 95% CI 0.90 to 1.32; 11 exposed cases).

Conclusions

Maternal exposure to leflunomide during pregnancy was not associated with statistically significant increased risk of MCMs, prematurity, LBW or spontaneous abortions. However, given that relatively few women were exposed to leflunomide during pregnancy in this cohort, caution remains warranted.

Triplet Pregnancy in a Diabetic Mother With Kidney Transplant: Case Report and Review of the Literature

Triplet and higher-order multiple pregnancies can carry increased fetal and maternal complications. Reports of triplet pregnancies after kidney transplant are scarce and have been associated with perinatal complications. Presence of diabetes in such cases worsens both fetal and maternal outcomes. Here, we present a triplet pregnancy in a kidney transplant recipient with diabetes. We also reviewed the literature for causes, prevalence, and outcomes in association with chronic kidney disease, kidney transplant, and diabetes mellitus. The patient, a 31-year-female who received a living-donor kidney transplant, had a first-time pregnancy 6 years after transplant. Pregnancy was complicated by gestational diabetes, preeclampsia, and miscarriage. She continued to have postpartum-impaired glucose tolerance. She became pregnant again after 6 months but required insulin therapy during her third trimester. Pregnancy was terminated by cesarean section for a viable small boy. Two years later, she had triplet pregnancy after ovulation induction with clomiphene. Glycemic control was maintained using intensive insulin therapy guided by frequent home blood glucose monitoring (HbA1c was 5.8% at 22 wk). Both gynecologic care and nephrologic care were carried out through outpatient follow-up. Pregnancy was complicated by hypertension and mild renal dysfunction without proteinuria and ended in elective premature cesarean section at 32 weeks of gestation. She had 3 male babies with low birth weights (1320, 1380, 1275 g), with the largest baby developing sepsis and requiring an intensive care unit stay and then incubator for 49 days. The other 2 required incubators for 36 days. Their weights after 22 months were 9, 16, and 11 kg. The mother is now normotensive with normal renal function and impaired glucose tolerance. Care of diabetic kidney recipients with triplet pregnancy constitutes a special challenge requiring a multispecialty skilled team to ensure the best outcome.

Pregnancy in chronic kidney disease and kidney transplantation

Chronic kidney disease (CKD) affects up to 6% of women of childbearing age in high income countries, and is estimated to affect 3% of pregnant women. Advanced renal dysfunction, proteinuria, hypertension, and poorly controlled underlying primary renal disease are all significant risks for adverse maternal, fetal, and renal outcomes. In order to achieve the best outcomes, it is therefore of paramount importance that these pregnancies are planned, where possible, to allow the opportunity to counsel women and their partners in advance and to optimize these risks. These pregnancies should be deemed high risk and they require close antenatal monitoring from an expert multidisciplinary team. We discuss the effect of pregnancy on CKD, and also current guidelines and literature with specific reference to transplantation, autoimmune disease, and medication use in pregnancy. We also discuss the benefits of prepregnancy counseling and give practical recommendations to advise pregnant women with renal disease.

Lupus nephritis and renal disease in pregnancy

Management of pregnant women with renal disease involves awareness of, and allowance for, physiological changes including decreased serum creatinine and increased proteinuria. For women with systemic lupus erythematosus (SLE), pregnancy increases likelihood of flare. These can occur at any stage, and are more difficult to diagnose, as symptoms overlap those of normal pregnancy. Renal involvement is no more common in pregnancy. Worsening proteinuria may be lupus flare but differential includes pre-eclampsia. In women with chronic renal disease, pregnancy may accelerate decline in renal function and worsen hypertension and proteinuria, with increased risk of maternal (eg, pre-eclampsia) and fetal (eg, IUGR, IUD) complications, strongly correlating with degree of renal impairment peri-conception. Pregnancy success rate varies from 20% to 95% depending on base-line creatinine. Best outcome is obtained if disease was quiescent for >6 months pre-conception. Women on dialysis or with renal transplants can achieve successful pregnancy but have higher maternal and fetal complication rates. Acute on chronic renal failure can develop secondary to complications such as HELLP and AFLP. Management needs to be by a multidisciplinary team involving physicians and obstetricians, ideally beginning with pre-pregnancy counselling. Treatment of flares includes corticosteroids, hydroxychloroquine, azothioprine, NSAIDs and MMF. Blood pressure is controlled with methyldopa, nifedipine or hydralazine.

Uterus transplantation: current progress and future prospects

Even if reproductive medicine has been remarkably successful during the past few decades, with the introduction of in vitro fertilization in the late 1970s and intracytoplasmic sperm injection in the early 1990s, it has been repeatedly mocked by infertility due to an absolute uterine factor. No treatment has been available for the women suffering from an absent or dysfunctional uterus, in terms of carrying a pregnancy. Approximately one in 500 women suffer from absolute uterine infertility, and the option so far to become a mother has been to either adopt or utilize gestational surrogacy. As of today, a total of eleven cases of human uterus transplantations have been reported worldwide, conducted in three different countries. The results of these initial experimental cases far exceed what might be expected of a novel surgical method. Many more uterus transplantations are to be expected in the near future, as other research teams' preparations are being ready to be put into clinical practice. In this review, we summarize the current worldwide experience of uterus transplantation as a treatment of absolute uterine factor infertility and the future prospects of human uterus transplantation.

Study on the effect of kidney transplantation on the health of the patients' offspring: a report on 252 Chinese children

Even though the incidence of pregnancies in the female recipients is lower and also chronic renal disease in male patients is associated with impaired spermatogenesis, the health of the children born to these patients was not studied. In this report, we discuss information on the growth and development of offspring of 248 male and female kidney recipient patients. Physical and routine clinical measurements of the 252 offspring (129 male and 123 female) born to these transplantation patients were made along with the intelligence tests. In some of these children chest X-ray and immune indices were assessed. Among the recipients, 219 males fathered 223 children with an average birth weight of 3,255 ± 374 g and 29 female recipients gave birth to 29 children with an average birth weight of 2,923 ± 551. While most of these children were normal, we noticed a case of soft double toe, a case of short tongue tie, five cases of marginal mental retardation, three cases of proteinuria, six cases of microscopic hematuria, 15 cases of low hemoglobin, and 21 cases with recurrent respiratory tract infections. We conclude that kidney transplantation has no significant impact on the growth, development, health, and intelligence of the offspring born to recipients.

Experimental uterus transplantation

Today, most causes of infertility are successfully treated. Yet there is still a subgroup of female infertility affecting around 4%, which so far is untreatable because of an absolute uterine factor. To acquire motherhood, these women are today referred to either adoption or surrogacy. Research in the field of uterus transplantation has been evaluated in different animal models for decades and has presently reached a human clinical application as a possible treatment for absolute uterine factor infertility. Organ transplantation is no longer reserved to those with a life-threatening disease and neither is organ transplantation together with concurrent immunosuppression prohibiting pregnancy. Uterus transplantation involves four parties - recipient, donor, partner of recipient and future child - and is a subject of ethical controversies.

Pregnancy in heart- and heart/lung recipients can be problematic

OBJECTIVE

The first successful pregnancy after heart transplantation was reported in 1988. Worldwide experience with heart and heart/lung transplanted (H-HLTx) pregnant women is limited. To expand this knowledge the collaborating Nordic thoracic transplant centers wanted to collect information on all such pregnancies from their centers.

DESIGN

Information was retrospectively collected on all H-HLTx pregnancies in the Nordic countries.

RESULTS

A total of 25 women have had 42 pregnancies and all survived the gestation. Minor complications were increasing incidence of proteinuria, hypertension and diabetes. Major problems were two rejections (early post partum), two severe renal failures, seven pre-eclampsias and 17 abortions. Five women died two to 12 years after delivery. Of 25 live born children, one was born with cancer and one died early after inheriting the mother's cardiomyopathy.

CONCLUSION

Pregnancy after H-HLTx can be successful for both mother and child. There are, however, many obstacles which should be addressed. Respecting the couple's desire for children the attitude should be carefully, not too optimistic, after proper pre-pregnant information and counseling. Delivery should preferably take place at the transplant center.

Leflunomide in the treatment of rheumatoid arthritis

Rheumatoid arthritis is a chronic and highly morbid disease affecting approximately 1% of the world's population. With the advent of disease-modifying antirheumatic drugs, patients are increasingly able to maintain control of their arthritis and prevent joint destruction. However, not all patients respond adequately to any single disease-modifying antirheumatic drug, and many newer parenteral therapies are cost prohibitive. Leflunomide, an inhibitor of pyrimidine biosynthesis, is the first oral disease-modifying antirheumatic drug to have been approved for rheumatoid arthritis in the USA in the last 15 years, and is now widely used in over 70 countries around the world. Leflunomide is efficacious when used as monotherapy or in combination with methotrexate to treat patients with rheumatoid arthritis, and is generally well tolerated. As clinical use increases, new ways to use leflunomide in order to minimize toxicity and maximize efficacy are being explored.

A pair of twins born after maternal exposure to leflunomide

Leflunomide is a drug used in rheumatoid arthritis with teratogenic and fetotoxic effects. Clinical data on human pregnancies are limited to a few case reports without detailed information whether the mothers did have a washout procedure as suggested by the manufacturer or what type of malformation the offspring showed. We report on a set of twins born after maternal exposure to leflunomide who had a largely normal neonatal outcome, providing information about the washout procedure and the blood level of the active metabolite.

[Autoimmune hepatitis and pregnancy: about a patient's three consecutive pregnancies]

Spontaneous evolution of autoimmune hepatitis during pregnancy is not well known, nor are its consequences on pregnancy evolution. Immunosuppressive treatment during pregnancy is sometimes necessary but the long- and short-term consequences are unrecognized. We relate a patient's disease with autoimmune hepatitis and cirrhosis and three consecutive pregnancies with different obstetrical and medical complications.

The impact of autoimmune disorders and adverse pregnancy outcome

Autoimmune diseases are a group of heterogeneous disorders equally characterized by the same pathogenetic mechanism: an immunological reaction against self antigens promoted by antibodies, immuno-complex formation, and self-reactive T lymphocytes. Autoimmune diseases may be separated into organ-restricted diseases and systemic ones. The damage of single organs produced by antibodies focused against specific cellular antigens characterizes the first group of diseases, whereas the latter are produced by a systemic inflammatory process initiated by inappropriate and excess immune activation that leads to immuno-complex formation and deposition onto sensitive tissues. Since connective and vascular tissue are principally damaged in these disorders, systemic autoimmune diseases are more commonly known as "connective tissue diseases" (CTD) and include: systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, Sjogren syndrome, and others. Although they are considered as different from a pathogenetic point of view, they overlap in many aspects, such as general symptoms as fever and fatigue, chronical ongoing, steroid therapy. As patients suffering from CTD are predominantly young women between the ages of 20 and 40 years, which is the period of the highest childbearing potential, particular interest must be regarded to the impact that these diseases and their therapies have on pregnancy and, conversely, the effect of pregnancy on these disorders, which may have long-lasting implications for mothers and neonates. Adverse fetal outcomes, maternal disease flares, and drug potential teratogenic risk are the main reasons why women suffering from CTD and who are pregnant or intend to become pregnant are considered a high-risk population. These patients require integrated, interdisciplinary care, addressing every aspect of rheumatology, obstetrics, and neonatology to reduce maternal, fetal, and neonatal complications.

Transgenic rescue of methotrexate-induced teratogenicity in Drosophila melanogaster

The folic acid analog methotrexate (MTX), a competitive inhibitor of dihydrofolate reductase (DHFR), is used to treat a variety of cancers and autoimmune disorders. However, MTX also causes a wide range of toxic effects in healthy cells and is an established teratogen. Efforts to "rescue" the defects caused by MTX by administering a folate analog or by transgenic expression of a DHFR with an altered affinity for MTX have been attempted in a variety of mammals but limited protection was conferred. As a result, our understanding of the effect of MTX at the molecular genetic level remains incomplete and, in addition, continued mammalian sacrifice is not ideal. Due to the similarity of teratogenic effects produced by MTX in Drosophila melanogaster these insects were transformed with DHFR alleles to determine if rescue could be achieved. The resulting "MTX-resistant" flies were subsequently used to investigate changes in gene expression in response to MTX using semiquantitative reverse transcription PCR. The majority (12/14) of key transcripts that were affected in MTX-exposed females including transcripts involved in cell cycle, defense response, and transport were "rescued" in the "MTX-resistant" transgenic flies. These studies illustrate the utility of this invertebrate model for the investigation of molecular effects of MTX-induced teratogenicity, MTX-resistant DHFRs for gene therapy techniques, and teratogenic protection.

Long-term care of the liver transplant recipient

As survival increases after liver transplantation, common issues that arise involve immunosuppression-related complications and primary health care. Proper emphasis on the prevention and treatment of post-liver transplant complications, such as diabetes mellitus, dyslipidemia, renal dysfunction, osteoporosis, and obesity, requires careful screening and long-term surveillance to minimize the progression of these complications. Active involvement by internists and subspecialists is necessary and a multidisciplinary approach should be undertaken. Liver transplantation should be viewed as a lifelong commitment by both patient and physician.

Outcome of pregnancy in patients with systemic lupus erythematosus

OBJECTIVE

To study the maternal and fetal outcomes in women with systemic lupus erythematosus (SLE).

MATERIALS AND METHODS

Over a period of 10 years, 24 pregnancies in 17 females with SLE in a single center were enrolled. Fetal and maternal outcomes were studied retrospectively.

RESULTS

The mean patient age was 27.7 years. Twenty-one of the 24 pregnancies occurred in the period of disease remission at the time of conception. Proteinuria presented in 12 pregnancies; however, no patient developed acute renal failure or deterioration of renal function. There were three cases of preeclampsia in this study. Two patients had their disease flare up and delivered stillborns. One woman with secondary antiphospholipid syndrome (APS) had a fetal loss. There was no maternal mortality. The mean gestation age was 34.3 weeks (range, 17-41 weeks), and the mean birth weight was 2,179 g. The mean APGAR scores were 8 and 9 at 1 and 5 minutes, respectively. One baby with congenital atrioventricular block was born to a mother with positive anti-SSA antibody. There were five cases (20.8%) of intrauterine growth retardation and 10 preterm deliveries (41.6%) in this study.

CONCLUSION

Pregnancy is relatively safe in women with SLE in remission but should be considered as a high-risk pregnancy. APS is associated with poor pregnancy outcome. The patient needs to cooperate with obstetricians and physicians for optimal disease control and detailed monitoring throughout the gestation.

Lupus and pregnancy: complex yet manageable

Systemic lupus erythematosus is a chronic multi-system autoimmune disease that occurs predominantly in women of childbearing age. The risk of complications and adverse fetal outcomes in pregnant women with lupus is high. Moreover, pregnancy can cause flares of lupus disease activity necessitating maternal immunosuppressive intervention. Interestingly, many potential complications of pregnancy present as symptoms of lupus making diagnosis and treatment a challenge. Advancing technology and better understanding of the maternal-fetal dyad in lupus have improved outcomes in lupus pregnancies over the last 40 years. This article will briefly review the important issues in pregnancies complicated by lupus and provide a general guideline to physicians for monitoring and treatment.

The use of antirheumatic disease drugs during pregnancy

Many connective tissue diseases occur more frequently in women, the female:male ratio for systemic lupus erythematosus is 9:1 and for rheumatoid arthritis is 3:1. These diseases frequently afflict young women, many of whom wish to become mothers. While some diseases (for example, rheumatoid arthritis) generally improve during pregnancy, other immune-mediated diseases may be exacerbated by pregnancy, putting both the mother and fetus at risk and making control of maternal disease a top priority. This review examines the current literature pertaining to the use of antirheumatic drugs during pregnancy, including aspirin and nonsteroidal anti-inflammatory drugs, corticosteroids, anticoagulants, the 4-aminoquinoline antimalarial drugs, immunomodulating drugs, antimetabolite drugs and other agents including sulfasazine and anticytokine therapy.

Th2 immune deviation induced by pregnancy: the two faces of autoimmune rheumatic diseases

One of the most important immunological modifications during pregnancy is the Th1/Th2 shift, due to the progressive increase of progesterone and estrogens during pregnancy, which reach their peak-level in the third trimester of gestation. At high levels, estrogens seem mainly to suppress Th1 cytokines and stimulate Th2-mediated immunological responses as well as antibody production. For this reason Th1-mediated diseases, like rheumatoid arthritis (RA), tend to improve and Th2-mediated disease, like systemic lupus erythematosus (SLE), tend to worsen during pregnancy. SLE is the autoimmune rheumatic disease in which pregnancy most frequently occurs because it predominantly affects young females in their childbearing age. Other autoimmune rheumatic diseases, including RA, are less frequently observed during pregnancy due to their low female-to-male ratio and peak onset after the age of 40. This review is focused on the disease course, gestational outcome and management of patients with SLE and RA during pregnancy.

Disease-Modifying Antirheumatic Drugs in Pregnancy

Drug use during pregnancy is sometimes unavoidable, especially in chronic inflammatory diseases such as rheumatoid arthritis (RA). The use of disease-modifying antirheumatic drugs (DMARDs) often starts in the early stage of RA; therefore, women of reproductive age are at risk for exposure to a DMARD at time of conception as well as during pregnancy. The aim of this paper was to review recent literature about DMARDs used for rheumatic diseases in pregnancy and to describe the type of study designs and results reported.Twenty-nine studies; eight on hydroxychloroquine/chloroquine, thirteen on methotrexate, three on sulfasalazine and six on azathioprine were identified. With respect to hydroxychloroquine, most studies concluded that it could be safely used in systemic lupus erythematosus or RA. The same conclusions were drawn from the azathioprine studies, but the available evidence is scarce. Although the evidence regarding the safety of methotrexate during pregnancy is conflicting, a high rate of pregnancy losses indicates a risk to the fetus. For each individual case it must be decided whether the benefits outweigh the potential risks. No major teratogenic effects of sulfasalazine were seen although teratogenic effects still can not be excluded. For all other DMARDs, the information on their use in pregnancy was limited. This review underscores the gross absence of data on safety and risks of DMARD use during conception and pregnancy. While young women use these drugs in pregnancy, this review stresses the importance of good monitoring and further research.

Reproduction and transplantation: report on the AST Consensus Conference on Reproductive Issues and Transplantation

It has been almost 50 years since the first child was born to a female transplant recipient. Since that time pregnancy has become common after transplantation, but physicians have been left to rely on case reports, small series and data from voluntary registries to guide the care of their patients. Many uncertainties exist including the risks that pregnancy presents to the graft, the patient herself, and the long-term risks to the fetus. It is also unclear how to best modify immunosuppressive agents or treat rejection during pregnancy, especially in light of newer agents available where pregnancy safety has not been established. To begin to address uncertainties and define clinical practice guidelines for the transplant physician and obstetrical caregivers, a consensus conference was held in Bethesda, Md. The conferees summarized both what is known and important gaps in our knowledge. They also identified key areas of agreement, and posed a number of critical questions, the resolution of which is necessary in order to establish evidence-based guidelines. The manuscript summarizes the deliberations and conclusions of the conference as well as specific recommendations based on current knowledge in the field.

[Pleading to maintain hydroxychloroquine throughout Lupus pregnancies]

PURPOSE

The use of Hydroxychloroquine (HCQ) during pregnancy has remained controversial for a long time. However, it is generally agreed that pregnancy per se increases disease activity in patients with systemic lupus erythematosus (SLE) and that withdrawal of HCQ at the onset of pregnancy may result in exacerbation of SLE. Therefore, stopping HCQ at the onset of pregnancy may result in exacerbation of SLE which could be detrimental to both mother and fetus.

CURRENT KNOWLEDGE AND KEY POINTS

The available data suggest that HCQ can be continued safely throughout pregnancy. After the first report by Parke of successful continuation of HCQ throughout gestation, more than 250 pregnancies resulting in live births have been reported and no increase in the rate of birth defects have been demonstrated. When studied, no retinal toxicity and ototoxicity have been found in the children. Data concerning lactation and HCQ treatment are rare. However, the amount of HCQ received by children through lactation seems very low.

FUTURE PROSPECTS AND PROJECTS

For patients with SLE already taking HCQ, the benefits of continuing treatment with this medication throughout pregnancy seem to outweigh the hypothetical risks associated with its use. HCQ should probably be maintained throughout pregnancy in these patients with SLE and it does not seem necessary to advise against breastfeeding. Further studies with prospective follow-up of children exposed in utero to HCQ remain however needed to provide a definitive answer.

Safety of hydroxychloroquine in pregnant patients with connective tissue diseases. Review of the literature

Hydroxychloroquine (HCQ) is widely used in the treatment of systemic lupus erythematosus (SLE). Even if it is generally agreed that pregnancy per se increases disease activity in patients with SLE and that withdrawal of HCQ at the onset of pregnancy may result in exacerbation of SLE, use of HCQ during pregnancy has remained controversial for a long time. Parke was the first to propose continuation of HCQ throughout gestation. Currently, more than 250 pregnancies resulting in live births have been reported and no increase in the rate of birth defects have been demonstrated. When studied, no retinal toxicity and ototoxicity have been found. Data concerning lactation and HCQ treatment are rare. However, the amount of HCQ received by children through lactation seems very low. In conclusion, HCQ should probably be maintained throughout pregnancy in patients with SLE and it does not seem necessary to advise against breastfeeding.
