Pregnancy morbidity is one of the clinical manifestations used for classification criteria of antiphospholipid syndrome (APS). During the 14th International Congress on Antiphospholipid Antibodies (aPL), a Task Force with internationally-known experts was created to carry out a critical appraisal of the literature available regarding the association of aPL with obstetric manifestations present in actual classification criteria (recurrent early miscarriage, fetal death, preeclampsia and placental insufficiency) and the quality of the evidence that treatment(s) provide benefit in terms of avoiding recurrent adverse obstetric outcomes. The association of infertility with aPL and the effectiveness of the treatment of patients with infertility and positive aPL was also investigated. This report presents current knowledge and limitations of published studies regarding pregnancy morbidity, infertility and aPL, identifying areas that need better investigative efforts and proposing how critical flaws could be avoided in future studies, as suggested by participants of the Task Force. Except for fetal death, there are limitations in the quality of the data supporting the association of aPL with obstetric complications included in the current APS classification criteria. Recommended treatments for all pregnancy morbidity associated to APS also lack well-designed studies to confirm its efficacy. APL does not seem to be associated with infertility and treatment does not improve the outcomes in infertile patients with aPL. In another section of the Task Force, Dr. Jane Salmon reviewed complement-mediated inflammation in reproductive failure in APS, considering new therapeutic targets to obstetric APS (Ob APS).

Background:Cervical cancer (CC) is still the second in prevalence and mortality among women. In spite of previously observed higher incidence of cervical dysplasia among systemic lupus erythematosus (SLE) patients, few studies have considered the influence of classic risk factors and the use of immunosuppressors (IM). Objectives:To study cervical dysplasia prevalence among SLE patients submitted or not to immunosuppression and to evaluate its association with classic risk factors. Methods:A group of 171 SLE patients including 87 who were receiving IM continuously for at least 1 year was compared with 222 age- and sociocultural-paired women (control group) submitted to routine cervical cytopathology. Statistical methods included univariate and multivariate analysis, besides parametric and nonparametric tests. Results:The prevalence of atypical squamous cells of undetermined significance, low-grade and high-grade intraepithelial lesions were significantly increased in SLE patients (12.8%, 5.8%, and 3.5%, respectively) compared with controls (3.1%, 0.9%, and none, respectively, P = 0.0001), although they presented significantly fewer classic risk factors for CC. Multivariate analysis showed that SLE women had a 7-fold higher prevalence of cervical dysplasia (OR: 7.23, 95% IC: 3.40–15.38) and an 11-fold higher prevalence of premalignant cervical dysplasia (OR: 11.36, 95% IC: 2.57–50.10) compared with controls. SLE patients with long-term use of IM presented even higher prevalence of low-grade and high-grade intraepithelial lesions in comparison with those without long-term use of these agents (68.7% vs. 31.1%, P = 0.03). Conclusions:This study provides evidence that even though not presenting the classic risk factors for CC, SLE patients, especially those exposed to long-term immunosuppression, have increased chances of presenting more premalignant lesions than the general population and they probably need to follow a more stringent CC prevention program.

Pregnancy Morbidity in Antiphospholipid Syndrome: What Is the Impact of Treatment?

Guilherme R. de Jesús; Gustavo Rodrigues; Nilson R. de Jesús; Roger A. Levy

Women with persistently circulating antiphospholipid antibodies (aPL) have a higher incidence of recurrent abortions, fetal losses, pre-eclampsia, and placental insufficiency. Current treatment of patients with antiphospholipid syndrome (APS) during pregnancy with heparin and aspirin can act by preventing clot formation and improving live birth rates, but other obstetric morbidities remain high, especially in patients with a history of thrombotic events. In addition to the classical thrombotic placental events, other factors involving inflammation and complement activation seem to play a role in certain complications. In this article, we will review how medications interfere in the pathogenic mechanisms of APS, discuss the impact of current recommended treatment on pregnancy morbidity, and analyze new promising therapies.

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.

Antiphospholipid Antibodies and Antiphospholipid Syndrome during Pregnancy: Diagnostic Concepts.

Roger A. Levy; Flávia C. dos Santos; Guilherme R. de Jesús; Nilson R. de Jesús

Antiphospholipid syndrome (APS) comprises of a wide spectrum of clinical and obstetric manifestations linked to the presence of antiphospholipid antibodies (aPL). APS was described in the context of lupus, and later as an isolated syndrome or primary APS. The presence of aPL, especially the lupus anticoagulant test, is associated with adverse pregnancy outcomes, such as fetal death, recurrent early miscarriages, pre-eclampsia, and placental insufficiency, but does not seem to influence infertility. High quality scientific data to support these associations, however, are lacking, and controversies arise about the definition of positive aPL (low vs medium-high titers) or even the definition of the adverse events. This review discusses APS classification criteria and the current debate about it.

The hidden world of anti-phospholipid antibodies and female infertility: A literature appraisal

Cecilia Beatrice Chighizola; Guilherme R. de Jesús; D. Ware Branch

Even though the association of anti-phospholipid antibodies (aPL) with infertility is debated, infertile women are commonly screened for aPL. To review evidence, a systematic PubMed search was conducted to retrieve papers addressing (i) the association between aPL and infertility, (ii) the positivity rate of criteria and non-criteria aPL in women with infertility, (iii) the association between aPL and assisted reproduction technologies (ART) outcome, (iv) the efficacy of medical treatments on ART outcome, and (v) the effects of ART on thrombotic risk. A total of 46 papers were considered; several limitations emerged: (i) wide heterogeneity in study populations, (ii) non-prospective design in 90% of studies, and (iii) aPL cutoffs not conforming to international guidelines in more than 75% of studies; aPL positivity not confirmed in 89% of studies. Most studies evinced an association between infertility and anti-β2GPI antibodies and almost all non-criteria aPL. The association rate with infertility was below 50% for lupus anti-coagulant, anti-cardiolipin antibodies (aCL), and anti-phosphatidic acid antibodies. According to our estimates, overall positivity rates of criteria and non-criteria aPL tests are 6% and 3% among infertile women, 1% and 2% among controls, respectively. A significant difference in the positivity rate of patients versus controls emerged for aCL only. Five of 18 studies reported a detrimental effect of aPL on ART outcome. Only one of the six studies assessing the effects of treatment on ART outcome among aPL-positive infertile women reported a benefit. All relevant studies reported no increase in the rate of thrombosis among aPL-positive women undergoing ART.

This article describes three complicated cases in rheumatology and pregnancy. The first case elucidates the challenges in treating SLE in conjunction with pulmonary arterial hypertension, while the second case features an SLE-affected pregnancy with development of portal hypertension secondary to portal vein thrombosis related to APS. The third case is a pregnant woman with stable SLE who developed thrombotic microangiopathy caused by atypical haemolytic uraemic syndrome, and failed to improve despite multiple measures including biopsy and elective preterm delivery. There are grave and unique challenges for women with autoimmune disease, but adverse outcomes can sometimes be avoided with careful and multidisciplinary medical management. Pre-conception counselling with regard to medications and disease treatment should also include discussion of the advisability of pregnancy, which may be difficult for a patient, but present the best course for optimizing health outcomes.

Although systemic lupus erythematosus (SLE) is the most common autoimmune disease associated with antiphospholipid antibodies (aPL), limited data exist regarding the impact of SLE on the clinical phenotype of aPL‐positive patients. The primary objective of this study was to compare the clinical, laboratory, and treatment characteristics of aPL‐positive patients with SLE with those of aPL‐positive patients without SLE.
