Non-biologic immunosuppressive drugs for inflammatory and autoimmune skin diseases

Non-biologic immunosuppressive drugs, such as azathioprine, dapsone or methotrexate are fundamental treatment options for a wide range of autoimmune and chronic inflammatory skin diseases. Some of these drugs were initially used for malignancies (e.g., azathioprine or methotrexate) or infectious diseases (e.g., hydroxychloroquine or dapsone) but are nowadays mostly used for their immunosuppressive/immunomodulating action. Although dermatologists have years of clinical experience with these drugs, some of the mechanisms of action are not fully understood and are the subject of research. Although these drugs are commonly used, lack of experience or knowledge regarding their safety profiles and management leads to skepticism among physicians. Here, we summarize the mechanism of action and detailed management of adverse effects of the most commonly used immunosuppressive drugs for skin diseases. Furthermore, we discuss the management of these drugs during pregnancy and breastfeeding, as well as their interaction and handling during vaccination.

Nicht-Biologika-Immunsuppressiva bei entzündlichen und autoimmunen Hautkrankheiten: Non-biologic immunosuppressive drugs for inflammatory and autoimmune skin diseases

Nicht‐Biologika‐Immunsuppressiva wie Azathioprin, Dapson oder Methotrexat sind grundlegende Behandlungsmöglichkeiten für ein breites Spektrum von Autoimmunerkrankungen und chronisch‐entzündlichen Hauterkrankungen. Einige dieser Medikamente wurden ursprünglich bei malignen Erkrankungen (zum Beispiel Azathioprin oder Methotrexat) oder Infektionskrankheiten (zum Beispiel Hydroxychloroquin oder Dapson) eingesetzt, werden aber heute hauptsächlich wegen ihrer immunsuppressiven/immunmodulierenden Wirkung verwendet. Obwohl Dermatologen über jahrelange klinische Erfahrung mit diesen Arzneimitteln verfügen, sind einige der Wirkmechanismen noch nicht vollständig geklärt und noch Gegenstand der Forschung. Obwohl diese Medikamente häufig eingesetzt werden, führen mangelnde Erfahrung oder fehlendes Wissen über ihre Sicherheitsprofile und ihr Management zu einer skeptischen Haltung bei den Ärzten. Hier fassen wir den Wirkmechanismus und das detaillierte Management der Nebenwirkungen der am häufigsten verwendeten immunsuppressiven Medikamente für Hautkrankheiten zusammen. Darüber hinaus diskutieren wir den Umgang mit diesen Medikamenten während der Schwangerschaft und Stillzeit sowie ihre Wechselwirkung und Handhabung im Zusammenhang mit Impfungen.

Folate in maternal rheumatoid arthritis-filial autism spectrum disorder continuum

Rheumatoid Arthritis (RA) is an inflammatory autoimmune disease that affects women three times more than men. Epidemiological studies found that the incidence of Autism Spectrum Disorder (ASD), a neurological and developmental disorder, in children born to mothers suffering from RA is higher compared with the control population. Considering that the pathogenesis of ASD could be traced back to pregnancy and in uterine conditions, and the evidence of reduced folate levels in the brain of ASD-affected children, we aimed to study the role of folate, as an important nutritional factor during pregnancy, in associating maternal RA to ASD development in the offspring. Folate balance during RA could be influenced twice, initially during the immune activation associated with disease onset, and later during the treatment with anti-folate drugs, with a potential consequence of folate deficiency. Maternal folate deficiency during pregnancy could increase homocysteine levels, oxidative stress, and global DNA hypomethylation, all known risk factors in ASD pathogenesis. These effects could be intensified by genetic polymorphisms in the folate system, which were also found as genetic risk factors for both RA and ASD. The available evidence suggests that folate level as an important factor during RA, pregnancy and ASD could have pathological and therapeutical significance and should be carefully monitored and investigated in the RA-pregnancy-ASD axis.

Urticaria in Pregnancy and Lactation

Chronic urticaria (CU) is a mast cell-driven chronic inflammatory disease with a female predominance. Since CU affects mostly females in reproductive age, pregnancy is an important aspect to consider in the context of this disease. Sex hormones affect mast cell (MC) biology, and the hormonal changes that come with pregnancy can modulate the course of chronic inflammatory conditions, and they often do. Also, pregnancy-associated changes in the immune system, including local adaptation of innate and adaptive immune responses and skewing of adaptive immunity toward a Th2/Treg profile have been linked to changes in the course of inflammatory diseases. As of now, little is known about the effects of pregnancy on CU and the outcomes of pregnancy in CU patients. Also, there are no real-life studies to show the safety of urticaria medications during pregnancy. The recent PREG-CU study provided the first insights on this and showed that CU improves during pregnancy in half of the patients, whereas it worsens in one-third; and two of five CU patients experience flare-ups of their CU during pregnancy. The international EAACI/GA2LEN/EuroGuiDerm/APAAACI guideline for urticaria recommends adopting the same management strategy in pregnant and lactating CU patients; starting treatment with standard doses of second-generation (non-sedative) H1 antihistamines, to increase the dose up to 4-folds in case of no response, and to add omalizumab in antihistamine-refractory patients; but also emphasizes the lack of evidence-based information on the safety and efficacy of urticaria treatments during pregnancy. The PREG-CU study assessed treatments and their outcomes during pregnancy. Here, we review the reported effects of sex hormones and pregnancy-specific immunological changes on urticaria, we discuss the impact of pregnancy on urticaria, and we provide information and guidance on the management of urticaria during pregnancy and lactation.

A review of pruritus in pregnancy

Pruritus is a common dermatologic complaint during pregnancy. Pruritus is reported by 23-38% of women during pregnancy, and 2% report severe pruritus. In addition to interfering with sleep and reducing overall quality of life during pregnancy, pruritus may be the first, or only, symptom of an underlying disorder that may impact maternal and fetal outcomes. It is therefore critical for all providers caring for pregnant women to be familiar with pregnancy-specific and non-specific conditions associated with pruritus to most effectively manage this unique population. In this review, we discuss clinical classification of pruritus, a practical approach to the differential diagnosis of pruritus in pregnancy, and focus on updates in the clinical features, diagnosis, management, and prognosis of pregnancy-specific causes of pruritus.

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.

The positive effect of pregnancy in rheumatoid arthritis and the use of medications for the management of rheumatoid arthritis during pregnancy

Rheumatoid arthritis (RA) is an autoimmune systemic inflammatory disorder that is mostly characterised by progressive symmetrical joint destruction, particularly in the wrist and fingers, while it may also affect additional joints and several organs, such as the skin, heart, blood vessels, and lungs. It is identified by raised anti-rheumatoid factor and anti-cyclic citrullinated peptide antibodies. The chemical mediators involved in the activity of RA are IL-1β, TNF-α, and IL-6. Pregnancy exerts a positive effect on RA that helps to modulate the disease condition. Different hypotheses are recommended to explain the ameliorating effect of pregnancy in RA. RA cannot be completely cured. The treatment goal is the attrition of pain and inflammation and the further progression of the disease. Long-term management of RA is carried out using disease-modifying antirheumatic drugs (DMARDs). Therapy of acute flares can be done with Non-steroidal anti-inflammatory drugs (NSAIDs) accompanied by ad interim usage of glucocorticoids. Biologic response modifiers are also available; they act by abolishing the activity of T- cells. However, it is necessary to select the correct treatment regimen when it comes to the management of RA in pregnancy.

Fertility and sexuality of women with inflammatory arthritis

OBJECTIVE

This study aimed to evaluate the impact of the four main types of inflammatory arthritis (rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PA), juvenile chronic arthritis (JCA)) on female fertility.

DESIGN

We performed a monocentric observational study, which took place in the Reproductive Medicine Department and the Rheumatology Department of the Toulouse University Hospital. An anonymous questionnaire was sent to patients aged 18-50 with RA, AS, PA or JCA who were diagnosed before the age of 40 and who consented to participate in the study. A section of the questionnaire was completed using the medical file of each patient.

RESULTS

Of the 521 eligible patients, 202 (39 %) answered the questionnaire. Before being diagnosed with a rheumatic disease, 87 % of patients with a desire for pregnancy had a spontaneously obtained live birth, compared to 75 % after (P < 0.05). However, this decrease only concerned RA (90 % before diagnosis vs 68 % after; P < 0.05). This difference was due to a lower rate of pregnancies achieved, but the number of miscarriages did not increase. Moreover, for patients who managed to conceive, the time required for conception did not increase, regardless of the type of rheumatic disease they had. Two thirds of patients reported a decrease in the frequency of sexual intercourse after diagnosis, mainly (75 %) because of the pain relating to the disease.

CONCLUSION

Our study shows a trend of decreased fertility in patients with RA, perhaps due to sexual problems, while no impact of AS and PA on the ability to conceive was found. This impact on fertility didn't seem to be related to the decrease of sexuality. Multidisciplinary care including treatment from a rheumatologist, gynecologist and sexologist would appear essential in order to provide RA patients with the necessary information concerning their fertility, answer their questions about pregnancy and thus optimize their care.

What factors could influence physicians' management of women of childbearing age with chronic inflammatory disease? A systematic review of behavioural determinants of clinical inertia

BACKGROUND

Pregnancy represents a complex challenge to clinicians treating women with chronic inflammatory disease. Many clinicians face a situation of heightened sensitivity to the potential risks and uncertainties associated with the effect of pharmacological treatment on pregnancy outcomes. This may create an environment vulnerable to clinical inertia, whereby behavioural factors such as cognitive heuristics and biases, and other factors such as attitudes to risk and emotion can contribute. This systematic review was undertaken to assess if clinical inertia has been investigated/identified in this setting and took a behavioural science approach to identify and understand the potential determinants of clinical inertia in this treatment setting.

METHODS

A systematic literature search was conducted to identify publications which investigated or described clinical inertia or its determinants (e.g. heuristics, biases etc.). Results were coded for thematic analysis using two inter-related behavioural models: the COM-B model and the Theoretical Domains Framework.

RESULTS

Whilst studies investigating or describing clinical inertia in this treatment setting were not identified, the behavioural analysis revealed a number of barriers to the pharmacological management of women of fertile age affected by chronic inflammatory disease. Factors which may be influencing clinician's behaviour were identified in all domains of the COM-B model. The primary factors identified were a lack of knowledge of treatment guidelines and fears concerning the safety of medications for mother and fetus. Lack of experience of treating pregnant patients was also identified as a contributing factor to undertreatment.

CONCLUSION

Using a behavioural approach, it was possible to identify potential factors which may be negatively influencing clinician's behaviour in this treatment setting, although specific research was limited.

A Population-level Analysis of the Differing Effects of Rheumatoid Arthritis and Spondyloarthritis on Peripartum Outcomes

OBJECTIVE

The effects of rheumatoid arthritis (RA) and spondyloarthritis (SpA) on maternal and neonatal outcomes at a population level have not previously been well compared.

METHODS

A contemporary pregnancy cohort of 312,081 women and corresponding birth events was assembled for the province of Alberta from the random selection of 1 live birth event per woman. We identified 3 groups: (1) no inflammatory arthritis (no IA, n = 308,989), (2) RA (n = 631), and (3) SpA (n = 2461). We compared maternal and neonatal outcomes, comorbid conditions, and medication use among the 3 groups. Multivariable logistic regression models evaluated the independent association between RA and SpA, relative to no IA, and the outcomes of small for gestation age (SGA) and hypertensive disorders during pregnancy.

RESULTS

Pregnant women with RA were significantly more likely to have preterm delivery (13.5%), cesarean delivery (33.9%), hypertensive disorders in pregnancy (10.5%), and SGA babies (15.6%), compared to pregnant women with either SpA or no IA. Nonsteroidal antiinflammatory drugs and corticosteroid use were significantly higher in pregnant women with RA compared to the other groups. Women with RA were significantly more likely to have an SGA baby (OR 1.51, 95% CI 1.21-1.88; p < 0.01), and hypertensive disorder in pregnancy (OR 1.51, 95% CI 1.16-1.97; p < 0.01), compared to women with no IA, while no difference was found between women with SpA and those with no IA.

CONCLUSION

Women with RA have a higher risk of worse maternal and neonatal outcomes, whereas the risk of these events is similar between women with and without SpA.

Breastfeeding among Women with Rheumatoid Arthritis Compared with the General Population: Results from a Nationwide Prospective Cohort Study

Objective.

The World Health Organization recommends that infants be exclusively breastfed until the age of 6 months. The first objective was to compare breastfeeding frequencies and time of cessation between women with rheumatoid arthritis (RA) and the general population. The second objective was to identify why patients with RA discontinue breastfeeding.

Methods.

This study was embedded in the Pregnancy-induced Amelioration of Rheumatoid Arthritis (PARA) study, a nationwide prospective cohort study. From 2002 to 2008, a total of 249 pregnancies were followed from pregnancy until 6 months postpartum. Data on lactation and medication use were collected. Proportion tests were used to compare percentages of breastfeeding between the study population and the general/reference population.

Results.

At 4–6, 12, and 26 weeks postpartum, 43%, 26%, and 9% of the RA patients breastfed their offspring, respectively, compared with 63%, 46%, and 41% in the general population, respectively (p < 0.001). The main reason for women to discontinue breastfeeding was the restart of medication (n = 129, 57.8%). Nevertheless, more than 40% of these patients restarted medication that was considered compatible with breastfeeding.

Conclusion.

This large prospective study demonstrates that RA is associated with lower proportions of women breastfeeding their offspring and earlier cessation compared with the general population. A considerable number of patients discontinued breastfeeding so that they could start medication, even though many of the medications are considered safe to use during lactation. Using the results of this study, intervention strategies supporting RA patients who wish to breastfeed may be developed.

Use of synthetic and biologic DMARDs during pregnancy

Introduction: Since most of the autoimmune diseases (AID) affect mostly women in their fertile years, and fertility is in general preserved, the use of disease-modifying antirheumatic drugs (DMARDs) during conception, pregnancy, and lactation has been a matter of concern in the treatment of women affected by AID. Areas covered: We performed a comprehensive review of the latest and most relevant research papers published in the field and discussed different aspects related to the use of synthetic and biologic DMARDs and immunosuppressants in the preconceptional period, during pregnancy and lactation in AID patients, both in males and females. Expert commentary: Active AID impose an increased risk for adverse maternal and fetal outcomes, such as preeclampsia, miscarriage, intrauterine growth restriction, prematurity, low birth weight, and stillbirth. Family planning with proper contraception and shared decision-making on the ideal time to conceive with treatment adjustment must be a rule. One of the main challenges when counseling and/or adjusting treatment of patients that are planning a pregnancy is to provide a medication that is at the same time efficacious and safe at the conceptional period and to developing the fetus.

Practical Pearls About Current Rheumatic Medications

New and existing rheumatic disease is frequently encountered in the primary care setting. The number of medications used to treat various rheumatic conditions continues to increase. Some medications have very specific indications, whereas others have increasing off-label uses. Regardless of the indication, the medications used in rheumatology have variable dosing recommendations, significant side effects, recommended monitoring parameters, and potential medication interactions. Clinicians need to be aware of the potential uses as well as possible pitfalls associated with medications used in rheumatology.

Maternal myasthenia gravis represents a risk for the child through autoantibody transfer, immunosuppressive therapy and genetic influence

Females with myasthenia gravis (MG) worry about their disease having negative consequences for their children. Autoimmune disease mechanisms, treatment and heredity could all have an impact on the child. This is a subject review where Web of Science was searched for relevant keywords and combinations. Controlled and prospective studies were included, and also results from selected and unselected patient cohorts, guidelines, consensus papers and reviews. Neonatal MG with temporary muscle weakness occurs in 10% of newborn babies where the mother has MG, due to transplacental transfer of antibodies against acetylcholine receptor (AChR), muscle-specific kinase (MuSK) or lipoprotein receptor-related protein 4 (LRP4). Arthrogryposis and fetal AChR inactivation syndrome with contractures and permanent myopathy are rare events caused by mother's antibodies against fetal type AChR. The MG drugs pyridostigmine, prednisolone and azathioprine are regarded as safe during pregnancy and breastfeeding. Methotrexate, mycophenolate mofetil and cyclophosphamide are teratogenic. Mother's MG implies at least a 10-fold increased risk for MG and other autoimmune diseases in the child. MG females should receive specific information about pregnancy and giving birth. First-line MG treatments should usually be continued during pregnancy. Intravenous immunoglobulin and plasma exchange represent safe treatments for exacerbations. Neonatal MG risk means that MG women should give birth at hospitals experienced in neonatal intensive care. Neonatal MG needs supportive care, rarely also acetylcholine esterase inhibition or intravenous immunoglobulin. Women with MG should be supported in their wish to have children.

Update on the prevalence and determinants of folic acid use in Japan evaluated with 91,538 pregnant women: the Japan Environment and Children's Study

Objective: To provide the latest and most promising evidence on the prevalence and determinants for folic acid supplementation in pregnant women in Japan, including differences in prevalence between interview years and determinants across regions.Materials and methods: The study participants were enrolled from 15 regional centers across Japan between January 2011 and March 2014. Information on the use of folic acid supplementation before and during pregnancy and the characteristics of the participants were collected using questionnaires, medical chart reviews, and interviews by research coordinators.Results: Data for 91,538 women who provided sufficient data on folic acid supplementation were analyzed. The prevalence of adequate users was 8.0%, which, although low, tended to improve over the 4-year recruitment period. Various kinds of sociodemographic factors, lifestyle habits, and obstetrical and medication use history were significant and independent determinants for folic acid use. Associations between adequate preconception folic acid use and its major determinants tended to be similar across regions.Conclusions: Although the prevalence of adequate folic acid use was low, it increased from 2011 to 2014. Reproductive-aged women who have determinants for inadequate folic acid use should be informed about the need for preconception folic acid supplementation to help prevent neural tube defects.

Chronic pain during pregnancy: a review of the literature

BACKGROUND AND PURPOSE

The majority of the reviews and studies on chronic pain in pregnancy have primarily focused on the pharmacological and non-pharmacological treatment options. The purpose of our review was to identify evidence-based clinical research for the evaluation and management of preexisting chronic pain in pregnancy, chronic pain associated with pregnancy, and chronic pain in relation to mode of delivery.

METHODS

A literature search was undertaken using the search engines PubMed, CINAHL, EBSCOhost, and Web of Science. Search terms used included "chronic pain" AND "pregnant OR pregnancy" OR "pregnancy complications" from inception through August 2016.

RESULTS

The basis of this review was the 144 articles that met inclusion criteria for this review. Based on our review of the current literature, we recommend 7 guidelines for chronic pain management during and after pregnancy: 1) complete history and physical examination; 2) monitor patients for alcohol, nicotine, and substance use; 3) collaborate with patient to set treatment goals; 4) develop a management plan; 5) for opioids, use lowest effective dose; 6) formulate a pain management plan for labor and delivery; and 7) discuss reproductive health with women with chronic pain.

CONCLUSION

The management of chronic pain associated with pregnancy is understudied. Obstetrical providers primarily manage chronic pain during pregnancy. Some general guidelines are provided for those health care providers until more information is available.

Successful pregnancy in the context of previously undiagnosed chronic lymphocytic leukaemia: A case report and literature review

An asymptomatic 36-year-old woman presented with significantly elevated white blood cells (165.9 × 10⁹/L) at antenatal booking, in her first pregnancy. Further investigations revealed the diagnosis of chronic lymphocytic leukaemia with monoallelic deletion of chromosome 13q14. She was supported and monitored through out pregnancy, without treatment, and delivered a healthy baby boy at term with no complications and is currently being followed up by the haem-oncology team.

New onset pemphigus foliaceus during pregnancy: A rare case

Pemphigus is a rare autoimmune disease during pregnancy. Among the different pemphigus types, pemphigus foliaceus (PF) is even rarer than pemphigus vulgaris. We present a case of PF in a 36-year-old female patient who presented with PF onset during pregnancy in the form of a disseminated, erythematosquamous rash. A diagnosis was made on the basis of histologic, immunofluorescence, and enzyme-linked immunosorbent assay results. A complete remission was recorded a month after steroid treatment initiation. The patient delivered a premature (33 weeks) but otherwise healthy baby girl. Only three cases of PF have been reported in two retrospective studies found in the English-language bibliography. Although pemphigus during pregnancy is a rare disease and treatment guidelines have not yet been elucidated, the management of these cases is individually evaluated. In all cases, the primary goal should be the control of the maternal disease along with the safety of the fetus.

The Influence of Methotrexate Treatment on Male Fertility and Pregnancy Outcome After Paternal Exposure

BACKGROUND

Inflammatory bowel disease incidence peaks during the reproductive years. Methotrexate (MTX) is frequently used for inflammatory bowel disease, but its use during pregnancy is contraindicated in women because of teratogenic effects. The aim of this review is to investigate the influence of MTX on male fertility and pregnancy outcomes after paternal MTX exposure.

METHODS

A systematic literature search was performed by applying 2 focus areas, "methotrexate" and "male fertility or pregnancy outcome." Terms and keywords were used both as MeSH terms and free-text searches. Pertinent articles were searched for additional relevant references.

RESULTS

In animal studies, MTX induces aberrations in sperm DNA that have not been identified in humans. The effects of MTX on human sperm quality have only been described in case reports. A transient adverse effect on sperm quality with low-dose MTX has been reported, but several other cases have not found harmful effects of MTX. MTX has not been measured in human sperm ejaculates; yet, the risk of a direct toxic effect on the fetus through MTX-contaminated seminal plasma seems negligible. Until now, 284 pregnancies with paternal MTX exposure have been reported. The outcomes were 248 live births and a total of 13 malformations, with no overt indication of MTX embryopathy.

CONCLUSIONS

This review reveals the lack of studies on the safety of MTX with regard to male reproduction. It is not clear whether MTX transiently influences male fertility and sperm DNA integrity, and more studies are needed. Comparative cohort studies found no increased risk of adverse pregnancy outcomes.

Critical review of the current recommendations for the treatment of systemic inflammatory rheumatic diseases during pregnancy and lactation

The crucial issue for a better pregnancy outcome in women with autoimmune rheumatic diseases is appropriate planning, with counseling of the ideal timing and treatment adaptation. Drugs used to treat rheumatic diseases may interfere with fertility or increase the risk of miscarriages and congenital abnormalities. MTX use post-conception is clearly linked to abortions as well as major birth defects, so it should be stopped 3months before conception. Leflunomide causes abnormalities in animals even in low doses. Although in humans, it does not seem to be as harmful as MTX, when pregnancy is detected in a patient on leflunomide, cholestyramine is given for washout. Sulfasalazine can be used safely and is an option for those patients who were on MTX or leflunomide. Azathioprine is generally the immunosuppressive of choice in many high-risk pregnancy centers because of the safety profile and its steroid-sparing property. Cyclosporine and tacrolimus can also be used as steroid-sparing agents, but experience is smaller. Although prednisone and prednisolone are inactivated in the placenta, we try to limit the dose to the minimal effective one, to prevent side effects. Antimalarials have been broadly studied and are safe during pregnancy and breastfeeding. Among biologic disease modifying anti-rheumatic agents (bDMARD), the anti-TNFs that have been used for longer are the ones with greater experience. The large monoclonal antibodies do not cross the placenta in the first trimester, and after conception, the decision to continue medication should be taken individually. The experience is larger in women with inflammatory bowel diseases, where anti-TNF is generally maintained at least until 30weeks to reduce fetal exposure. Live vaccines should not be administrated to the infant in the first 6months of life. Pregnancy data for rituximab, abatacept, anakinra, tocilizumab, ustekinumab, belimumab, and tofacitinib are limited and their use in pregnancy cannot currently be recommended.

Safety of anti-rheumatic drugs for rheumatoid arthritis in pregnancy and lactation

Women with rheumatoid arthritis (RA) are often of childbearing age and therefore questions regarding reproductive health and the use of medications, including disease-modifying anti-rheumatic drugs (DMARDs) may arise during the clinical consultation. Each patient requires individual assessment in order to effectively manage the disease while minimizing any treatment-associated risks to the fetus. Although good-quality controlled trials are lacking, there is an increasing volume of evidence surrounding the use of immunosuppressive therapies in pregnancy and lactation. This review summarizes the currently available information which can be of benefit to clinicians guiding patients and their families through the risks and benefits of continuing RA therapy during pregnancy and lactation. Further studies and ongoing surveillance of drug safety in pregnancy are required to resolve the uncertainties that remain regarding synthetic and biologic DMARDs.

Effects of prenatal exposure to cancer treatment on neurocognitive development, a review

Due to the increasing incidence of cancer during pregnancy, the need to better understand long-term outcome after prenatal exposure to chemo- and/or radiotherapy has become more urgent. This manuscript focuses on the neurocognitive development after prenatal exposure to cancer treatment. We will review possible pathways for brain damage that could explain the subtle changes in neurocognition and behavior found after in utero exposure to cancer treatment. Contrary to radiation, which has a direct effect on the developing nervous system, chemotherapy has to pass the placental and blood brain barrier to reach the fetal brain. However, there are also indirect effects such as inflammation and oxidative stress. Furthermore, the indirect effects of the cancer itself and its treatment, e.g., poor maternal nutrition and high maternal stress, as well as prematurity, can be related to cognitive impairment. Although the available evidence suggests that cancer treatment can be administered during pregnancy without jeopardizing the fetal chances, larger numbers and longer follow up of these children are needed.

The motherhood choices decision aid for women with rheumatoid arthritis increases knowledge and reduces decisional conflict: a randomized controlled trial

BACKGROUND

For many women with Rheumatoid Arthritis (RA) motherhood decisions are complicated by their condition and complex pharmacological treatments. Decisions about having children or expanding their family require relevant knowledge and consultation with their family and physician as conception and pregnancy has to be managed within the RA context. Relevant information is not readily available to women with RA. Therefore a randomized controlled study was conducted to evaluate the effectiveness of a new motherhood decision aid (DA) developed specifically for women with RA.

METHODS

One hundred and forty-four women were randomly allocated to either an intervention or control group. All women completed a battery of questionnaires at pre-intervention, including, the Pregnancy in Rheumatoid Arthritis Questionnaire (PiRAQ), the Decisional Conflict Scale (DCS), the Hospital Anxiety and Depression Scale (HADS), and the Arthritis Self-Efficacy Scale (ASES), and provided basic demographic information. Women in the DA group were sent an electronic version of the DA, and completed the battery of questionnaires for a second time post-intervention.

RESULTS

Women who received the DA had a 13 % increase in relevant knowledge (PiRAQ) scores and a 15 % decrease in scores on the decisional conflict (DCS), compared to the control group (1 %, 2 % respectively). No adverse psychological effects were detected as evident in unchanged levels of depression and anxiety symptoms.

CONCLUSIONS

The findings of this study suggest that this DA may be an effective tool in assisting women with RA when contemplating having children or more children.

Understanding and Managing Pregnancy in Patients with Lupus

Systemic lupus erythematosus (SLE) is a chronic, multisystemic autoimmune disease that occurs predominantly in women of fertile age. The association of SLE and pregnancy, mainly with active disease and especially with nephritis, has poorer pregnancy outcomes, with increased frequency of preeclampsia, fetal loss, prematurity, growth restriction, and newborns small for gestational age. Therefore, SLE pregnancies are considered high risk condition, should be monitored frequently during pregnancy and delivery should occur in a controlled setting. Pregnancy induces dramatic immune and neuroendocrine changes in the maternal body in order to protect the fetus from immunologic attack and these modifications can be affected by SLE. The risk of flares depends on the level of maternal disease activity in the 6–12 months before conception and is higher in women with repeated flares before conception, in those who discontinue useful medications and in women with active glomerulonephritis at conception. It is a challenge to differentiate lupus nephritis from preeclampsia and, in this context, the angiogenic and antiangiogenic cytokines are promising. Prenatal care of pregnant patients with SLE requires close collaboration between rheumatologist and obstetrician. Planning pregnancy is essential to increase the probability of successful pregnancies.

Management of urticaria: not too complicated, not too simple

In spite of being an old disease and apparently easy to diagnose, chronic spontaneous urticaria (CSU) is still perceived as an uncontrollable and difficult to manage disease. The perception of the patient is that his/her condition is not well understood and that is suffering from a disorder with hidden causes that doctors are not able to tackle. Sometimes patients go through a number of clinicians until they found some CSU expert who is familiar with the disease. It is surprising that myths and believes with no scientific support still persist. Guidelines are not widely implemented, and recent tools to assess severity are infrequently used. European and American recent guidelines do not agree in several key points related to diagnosis and treatment, which further contributes to confusion. With the aim to clarify some aspects of the CSU picture, a group of allergists and dermatologists from the Spanish Dermatology and Allergy societies developed a Frequent Asked Questions leaflet that could facilitate physicians work in daily practice and contribute to a better knowledge of common clinical scenarios related to patients with CSU.

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.

Chronic lymphocytic leukaemia, monoclonal B-lymphocytosis and pregnancy: five cases, a literature review and discussion of management

Chronic lymphocytic leukaemia (CLL) occurs rarely with pregnancy and monoclonal B-Lymphocytosis (MBL) has not previously been described in this setting. CLL is predominantly a disease of the elderly and affects men twice as often as women and hence only an estimated 2% of patients are females of childbearing age. We identified only five reported cases of CLL in pregnancy in the literature. We describe two additional cases, plus three other women with CLL dealing with pregnancy-related decisions. We review the literature and discuss proposals for management and issues that arise in this relatively uncommon occurrence. In contrast to many other haematological malignancies where longer remissions are typically associated with a lower risk of relapse, most patients with CLL who require treatment will ultimately relapse with current therapy. This complex setting requires careful consideration and well informed patients to assist with decisions related to pregnancy.

Diagnosis, pathogenesis and treatment of myositis: recent advances

Dermatomyositis (DM), polymyositis (PM), necrotizing myopathy (NM) and inclusion body myositis (IBM) are four distinct subtypes of idiopathic inflammatory myopathies - in short myositis. Recent studies have shed some light on the unique pathogenesis of each entity. Some of the clinical features are distinct, but muscle biopsy is indispensable for making a reliable diagnosis. The use of magnetic resonance imaging of skeletal muscles and detection of myositis-specific autoantibodies have become useful additions to our diagnostic repertoire. Only few controlled trials are available to substantiate current treatment approaches for myositis and hopes are high that novel modalities will become available within the next few years. In this review we provide an up-to-date overview of the pathogenesis and diagnostic approach of myositis. We aim to present a guide towards therapeutic and general management.

Current immunotherapy in rheumatoid arthritis

Rheumatoid arthritis is a common autoimmune disease primarily manifesting as chronic synovitis, subsequently leading to a change in joint integrity. Progressive disability and systemic complications are strongly associated with a decreased quality of life. To maintain function and health in patients with rheumatoid arthritis, early, aggressive and guided immunosuppressive therapy is required to induce clinical remission. Antirheumatic drugs are capable of controlling synovial inflammation and are therefore named 'disease-modifying antirheumatic drugs' (DMARDs). This article aims to bridge the beginning of DMARD therapy with agents such as methotrexate, leflunomide, sulfasalazine, injectable gold and (hydroxy)chloroquine with biological therapies, and with the new era of kinase inhibitors. Mechanisms of action, as well as advantages and disadvantages of DMARDs, are discussed with respect to the current literature and current recommendations.

Safety and tolerability of tumor necrosis factor-α inhibitors in psoriasis: a narrative review

Tumor necrosis factor (TNF)-α inhibitors are an alternative to oral systemic therapies for psoriasis. Data regarding the safety of TNF-α inhibitors from randomized clinical trials may not fully reflect the effects on the clinic patient population receiving the therapy, but other sources of information are available. We performed a literature review to assess the safety and tolerability of the treatment of moderate-to-severe plaque psoriasis with TNF-α inhibitors. A literature search was conducted using PubMed for articles dating from January 2000 to October 2013. Randomized controlled, cohort, open-label, and observational studies were included, as well as case reports and letters to the editor. Articles found on PubMed describing the safety of anti-TNF-α therapy in psoriasis patients were included, while studies highlighting interleukin (IL)-12 and IL-23 inhibitors were excluded, as were non-English articles. In total, 58 articles were included in the review. TNF-α inhibitors exhibit both efficacy and tolerability in patients with moderate-to-severe plaque psoriasis. Adverse effects associated with these medications are not common and can be minimized with routine clinical monitoring and patient education. While the risk of severe adverse events is low, the lack of very large, long-term, randomized safety trials limits the ability to fully define the safety of these agents. TNF-α inhibitors have a good efficacy/safety ratio for use in patients with moderate-to-severe psoriasis. Serious adverse effects are not common, and common injection-site reactions are usually manageable. The benefits of TNF-α inhibitors outweigh the risks for moderate-to-severe psoriasis; however, there are potential adverse effects and the patient populations at highest risk include the elderly and those with a history of malignancy.

Effects of fetal exposure to maternal chemotherapy

Approximately 1 in 1,000-2,000 pregnancies are complicated by cancer. Today, different treatment options are considered as safe during pregnancy: chemotherapy, radiotherapy, surgery, or a combination of these. Surgery is considered safe during all trimesters of pregnancy; radiotherapy can be administered during the first and the second trimester, and chemotherapy after the first trimester of pregnancy. The placenta, acting as a barrier between the mother and the fetus, plays a key role in the safe administration of chemotherapy during pregnancy. A few studies have investigated the short- as well as the long-term health, general development, and cognitive and cardiac outcomes on children exposed to chemotherapy in utero. In general, these results were reassuring. Nevertheless, better safety data are required. This means data with longer follow-up periods and comparison with appropriate control groups. Moreover, important biasing factors should be taken into account when interpreting these results. Firstly, a great proportion of children were born prematurely due to the maternal condition. Preterm birth in general has been associated with cognitive impairment. Secondly, cancer during pregnancy is clearly a stressful situation, and maternal stress is associated with attention deficits. In sum, we state that chemotherapy can be administered safely after the first trimester of pregnancy. Moreover, iatrogenic prematurity in order to start postpartum administration of chemotherapy should be avoided. Nonetheless, decisions concerning treatment in these specific cases should always be made in a multidisciplinary setting with internationally recognized expertise in the coexistence of cancer and pregnancy.

Are monoclonal antibodies a safe treatment for cancer during pregnancy?

Monoclonal antibodies (mAbs) are the cornerstone of the treatment of several types of tumors, but their use in pregnant women is not clearly defined. Here, we report and analyze all available data on mAb treatment in pregnant cancer patients. A literature search was performed from 2000 until January 2013 and all articles addressing safety of mAbs during pregnancy were reviewed. We found very few data on the use of bevacizumab in pregnant women. However, owing to its antiangiogenic effects and possible consequences on fetal development, it should be avoided during pregnancy. Trastuzumab administration has been associated with an elevated incidence of oligohydramnios and poor neonatal outcomes, particularly when prescribed after the first trimester for repeated infusions, and therefore it is not recommended. Rituximab does not seem to be teratogenic, but a transient prolonged neutropenia in the newborns was reported, without major infectious consequences in most cases. Few data are available about other mAbs, and hence their use during pregnancy remains discouraged.

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.
