Pregnancy is a special physical period in reproductive age women, which has a beneficial influence on the course of certain autoimmune diseases. It has been recently suggested that the microbiome undergoes profound changes during pregnancy that are associated with host physiological and immunological adaptations. The maternal microbiome remodeling during pregnancy is an active response of the mother, possibly to alter immune system status and to facilitate metabolic and immunological adaptations, which are needed for a successful pregnancy...

Guillain-Barré syndrome (GBS) is an autoimmune disease. Estimated population incidence ranges from 0.62 to 2.66 cases per 100,000 person-years across all age groups. We report a case of GBS in a 22-year-old primigravida who presented at 36 weeks of the period of gestation (POG), with complaints of bilateral progressive lower limb numbness and weakness for 2 weeks duration. Magnetic resonance imaging of the brain was done to exclude other possible causes. Diagnosis of GBS was made according to the Brighton criteria, which our patient falls into Level 2...

Background: Vitiligo vulgaris, an acquired disease related to autoimmune activity directed against melanocytes, is a common disorder of pigmentation affecting up to one percent of the population. Several autoimmune disorders are reported to improve during pregnancy-a state of relative immunosuppression. Objectives: To assess self-reported changes in vitiligo disease activity that occurred during pregnancy. Methods: A survey of 24 subjects with vitiligo was conducted by telephone using questions that pertained to vitiligo history, pregnancy history, and vitiligo disease activity prior to, during, and after pregnancy...

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...

Despite clear differences in immune system responses and in the prevalence of autoimmune diseases between males and females, there is little understanding of the processes involved. In this study, we identified a gene signature of immature-like neutrophils, characterized by the overexpression of genes encoding for several granule-containing proteins, which was found at higher levels (up to 3-fold) in young (20-30 y old) but not older (60 to >89 y old) males compared with females. Functional and phenotypic characterization of peripheral blood neutrophils revealed more mature and responsive neutrophils in young females, which also exhibited an elevated capacity in neutrophil extracellular trap formation at baseline and upon microbial or sterile autoimmune stimuli...

Conventional treatment of obstetric antiphospholipid syndrome fails in approximately 20-30% of pregnant women without any clearly identified risk factor. It is important to identify risk factors that are associated with these treatment failures. This study aimed to assess the impact of risk factors on pregnancy outcomes in women with obstetric antiphospholipid syndrome treated with conventional treatment. We carefully retrospectively selected 106 pregnancies in women with obstetric antiphospholipid syndrome treated with heparin + aspirin...

The protection exerted by neutrophils against invading microbes is partially mediated via the generation of neutrophil extracellular traps (NETs). In sterile conditions NETs are damaging species, enriched in autoantigens and endowed with the ability to damage the vessel wall and bystander tissues, to promote thrombogenesis, and to impair wound healing. To identify and reposition agents that can be used to modulate the formation of NETs is a priority in the research agenda. Low molecular weight heparins (LMWH) are currently used, mostly on an empirical basis, in conditions in which NETs play a critical role, such as pregnancy complications associated to autoimmune disease...

OBJECTIVE: To describe the obstetric outcomes associated with massive perivillous fibrin deposition (MFD) compared with a control series and to determine if outcome differs according to the extent of fibrin deposition. METHOD: Retrospective case-control study based on placentas analyzed over a consecutive 12-years period. MFD was considered severe if it extended over more than 50% of the placenta and moderate between 25 and 50%. RESULTS: During the study period, MFD was observed on 71 placentas, 39 severe and 32 moderate...

The HLA-G molecule presents immunomodulatory properties that might inhibit immune responses when interacting with specific Natural Killer and T cell receptors, such as KIR2DL4, ILT2 and ILT4. Thus, HLA-G might influence the outcome of situations in which fine immune system modulation is required, such as autoimmune diseases, transplants, cancer and pregnancy. The majority of the studies regarding the HLA-G gene variability so far was restricted to a specific gene segment (i.e., promoter, coding or 3' untranslated region), and was performed by using Sanger sequencing and probabilistic models to infer haplotypes...

The antiphospholipid syndrome (APS) is an autoimmune disorder characterized by an elevated risk for arterial and venous thrombosis and pregnancy-related morbidity. Since the discovery of the disease in 1980s, numerous studies in cell culture systems, in animal models, and in patient populations have been reported, leading to a deeper understanding of the pathogenesis of APS. These studies have determined that circulating autoantibodies, collectively called antiphospholipid antibodies (aPL), the majority of which recognize cell surface proteins attached to the plasma membrane phospholipids, play a causal role in the development of the disease...

Through a regulated or fortuitous phenomenon, small portions of cell nucleic acids are thrown into circulation. Since the discovery of these circulating nucleic acids (CNAs) in 1948, numerous studies have been published to elucidate their clinical implications in multifarious diseases. Scientists have now discovered disease-specific genetic aberrations, such as mutations, microsatellite alterations, epigenetic modulations (including aberrant methylation), as well as viral DNA/RNA from nucleic acids in plasma and serum...

: The incidence and prevalence of inflammatory liver diseases has increased over the last years but therapeutic options are limited. Pregnancy induces a state of immune tolerance, which can result in spontaneous improvement of clinical symptoms of certain autoimmune diseases including autoimmune hepatitis (AIH). We investigated the immune suppressive mechanisms of the human pregnancy hormone chorionic gonadotropin (hCG) in the liver. HCG signaling activates SIRT1, which deacetylates FOXO3a, leading to repression of pro-apoptotic gene expression...

Anti-phospholipid syndrome is an autoimmune disorder characterized by anti-phospholipid antibodies, arterial and venous thrombosis, pregnancy morbidity, and various neurological manifestations including psychiatric disorders. Higher incidence of various autoimmune disorders was found in schizophrenia. In addition, an association between the presence of anti-phospholipid antibodies and schizophrenia or psychosis was previously described, mainly as case reports. Although initially believed to be a result of neuroleptic treatment, the reasons for this association remain obscure...

S Grunewald, P Staubach
During pregnancy, a successful and safe therapeutic management of patients is possible to lower the burden of disease. Often topical therapy in combination with intensive basic skin care is sufficient. Drug therapies may also be used, most often for systemic diseases such as autoimmune diseases or psoriasis. An early change in therapy is also key during planned pregnancies so that treatments can be switched, adjusted, reduced or closely monitored. Another point to consider is to keep drug dosing as low as possible (without occlusion in local therapy) or short termed (with the exception of autoimmune or malignant diseases)...

Myasthenia gravis is an autoimmune disorder that is characterized by muscle weakness that fluctuates, worsening with exertion, and improving with rest. Diagnosis of myasthenia gravis is made following clinical and physical examination and is confirmed by serum immunoassays to measure autoantibody levels. Myasthenia gravis especially when associated with pregnancy is a high-risk disease, and its course is unpredictable. We described the second report about use of sugammadex after rocuronium for a caesarean delivery with myasthenia gravis, but, unlike our case that formerly was diagnosed with myasthenia gravis, the patient was extubated on postoperative successfully and we did not encounter any respiratory problems...

Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by thrombosis and/or pregnancy morbidity with persistent levels of antiphospholipid antibodies (aPLs). The development of thrombosis in APS is mediated by aPLs and contributes to the high mortality rate in APS patients. However, although APS has been reported for more than 30 years, there has been no optimal regimen for its prevention or for the management of thrombosis, mainly because the mainstay treatment strategies for managing APS are not targeted towards aPL-mediated thrombotic pathophysiology...

Tumor necrosis factor-α (TNF-α) is a central regulator of inflammation, and TNF-α antagonists may be effective in treating inflammatory disorders in which TNF-α plays a major pathogenic role. TNF-α has also been associated with inflammatory mechanisms related to implantation, placentation, and pregnancy outcome. TNF-α is secreted by immune cells and works by binding to TNFR1 and TNFR2 cell receptors. TNF-α is also related to JAK/STAT pathways, which opens up hypothetical new targets for modifying. The accurate balance between Th1 cytokines, mainly TNF-α, Th17, and Th2, particularly IL-10 is essential to achieve good obstetric outcomes...

To evaluate the diagnosis value of antibodies to phosphatidylserine/prothrombin complex (aPS/PT) in patients with antiphospholipid syndrome (APS) and to determine the clinical features of APS patients with avidity of aPS/PT. Serum samples were collected from 108 APS patients. Sixty patients with pregnancy morbidity, 37 patients with thrombosis without a history of autoimmune diseases, and 89 healthy blood donors were included as the control group. The enzyme-linked immunosorbent assay (ELISA) test was performed to detect the concentration of aPS/PT, including IgG/M, IgG, and IgM forms, in the same serum sample...

Pregnancy is one of the strongest inducers of immunological tolerance. Disease activity of many autoimmune diseases including multiple sclerosis (MS) is temporarily suppressed by pregnancy, but little is known about the underlying molecular mechanisms. Here, we investigated the endocrine regulation of conventional and regulatory T cells (Tregs) during reproduction. In vitro, we found the pregnancy hormone progesterone to robustly increase Treg frequencies via promiscuous binding to the glucocorticoid receptor (GR) in T cells...

BACKGROUND: Thyroid autoimmunity is a major risk factor for gestational thyroid disease, and recently various other risk factors have been identified, including maternal age, body mass index (BMI) and parity. Human chorionic gonadotropin (hCG) is an important determinant of gestational thyroid function, yet it is unknown to what extent differences in hCG concentration affect the risk for thyroid disease. We have recently shown that thyroperoxidase antibody positivity impairs the thyroidal response to hCG stimulation, which may suggest that this is a mechanism through which thyroid autoimmunity acts as a risk factor for thyroid disease...
