A pregnant patient at 38 weeks' gestation developed symptoms of local anaesthetic toxicity following intravenous regional anaesthesia (IVRA) for hand surgery, using a standard dose of lignocaine. Reports suggest that a number of factors, both physiological and pharmacological, combine to increase the likelihood of local anaesthetic (LA) toxicity in pregnancy ...

AIM: To compare the pregnancy outcome, in particular gestational age and birth weight in women with systemic lupus erythematosus (SLE) diagnosed before and after pregnancy, and to review data on presence or absence of the antiphospholipid (aPL) antibody and flares of disease activity. METHOD: Case histories were reviewed of women ...

The outlook of pregnancy for women with lupus nephritis is usually favourable if the disease has been quiescent for at least 3 months before pregnancy, and if, at conception, serum creatinine is less than 140 mumol/l, proteinuria less than 3 grams/25 hours and blood pressure controlled. The risk of fetal ...

One of the major targets of antiphospholipid antibodies (aPL) is the placenta, the evolution of which during pregnancy has been well documented. Histopathological findings are related to gestational age, and several physiologic and pathologic alterations that occur during its development. The major findings in placentae from aPL positive patients are ...

To elucidate the association between anticardiolipin antibody (aCL-Ab) or anti-cardiolipin beta-2-glycoprotein I-antibody (aCL-beta-2-GP I-Ab) and recurrent fetal miscarriage, the positive rates of aCL-Ab were assessed in 667 patients with recurrent fetal miscarriages and those of aCL-beta-2-GP I-Ab were assessed in 208 patients. The rates were then compared with the control ...

Neonatal lupus erythematosus is a disease primarily characterized by cardiac and/or cutaneous involvement. Liver and haematological involvement occur in a few cases and these are normally considered to be mild and transient complications. The disease is suspected to be caused by transplacental passage of maternal autoantibodies, primarily anti-Ro/SSA and anti-La/SSB, ...

Our purpose was to determine the prevalence of antiphospholipid antibodies (APA) in eclamptic women as well as the rates of intrauterine growth retardation (IUGR) and fetal death in APA-positive and -negative eclamptic women. Thirty-six eclamptic and 30 healthy pregnant women were enrolled in this study. APA in those groups were ...

AIMS: To study the distribution of clinically important red cell antibodies in pregnancy, and the associated fetal and neonatal morbidity and mortality.

Systemic lupus erythematosus and antiphospholipid antibody syndrome are associated with an increased risk of intrauterine growth restriction, miscarriage, stillbirth and premature delivery. Recent advances in therapy during pregnancy have improved the outcome but there is still significant fetal and maternal morbidity and mortality. Treatment of patients failing conventional therapy during ...

The antiphospholipid (APS) syndrome frequently includes severe pregnancy complications such as fetal wastage and recurrent spontaneous abortions. Animal models for APS in pregnancy can provide both an understanding of the pathogenic mechanisms of anti-phospholipid antibodies (aPL), and aid in the evaluation of various therapeutic modalities in APS. Animal models for ...

In pregnancy, pharmacokinetics of corticosteroids changes. Systemic corticosteroids are not teratogenic. Pregnant women receiving corticosteroid therapy suffer the same side effects and benefits as do treated women who are not pregnant. Clinical experience suggests no abnormalities of children of mothers treated with usual doses of prednisone and methylprednisolone throughout pregnancy, ...

Haemolytic disease of the newborn (HDN) caused by anti-Fy(a) is uncommon and usually mild. Current guidelines recommend that pregnant women with anti-Fy(a) are monitored less rigorously than those with anti-D, -c or -K. However, in a review of our recent experience of 68 pregnancies where anti-Fy(a) was detected, three were ...

Pregnancies occurring in women with antiphospholipid antibodies are at significantly increased risk of miscarriage, prematurity, intrauterine growth retardation and preeclampsia. Insights into the pathological basis of these conditions suggest that antiphospholipid antibodies impair embryonic implantation and in later gestations cause thrombosis of the uteroplacental vasculature. This offers a rational basis ...

OBJECTIVE: To review the management strategies and outcome in gravidas with anti-M isoimmunization over the past 26 years at The Ohio State University. METHODS: Data collected from 115 pregnancies found to have anti-M antibody at The Ohio State University from September 1969 through February 1996 were reviewed retrospectively. We analyzed ...

Disseminated intravascular coagulation is an imbalance between the coagulation and fibrinolytic systems. Hematologic changes that occur during pregnancy make this group of patients susceptible to triggers that upset the balance. Understanding normal hemostasis and the pathophysiology of disseminated intravascular coagulation, as well as conditions that are likely to precipitate this ...

Questionnaires (3426; 72.8%) and blood samples (3890; 82.6%) were analysed from 4704 women post-natally. The answers to the questionnaire confirmed that those patients living in areas with the highest percentage employed in agriculture were most likely to be in direct or indirect contact with sheep or sheep products. When the ...

It is still unclear whether i.v. immunoglobulins (Ig) can facilitate the reproductive prognosis of women who have suffered recurrent pregnancy loss. We report the results of a multicentre placebo-controlled study on the effect of Ig administration on pregnancy outcome in 46 women who had suffered at least three recurrent miscarriages. ...

OBJECTIVES: The mechanism by which antiphospholipid antibodies are associated with pregnancy loss and thromboembolism has not been established. We previously showed that annexin-V, a phospholipid-binding protein with potent anticoagulant activity, is present on the apical membranes of the syncytiotrophoblasts that line placental villi and that this protein is reduced, by ...

OBJECTIVE: To study serum levels of von Willebrand factor antigen (vWF:Ag) and anti-endothelial cell antibodies (AECA) in pregnancies with systemic lupus erythematosus (SLE) compared to healthy pregnancies and to evaluate their correlation with disease activity and fetal outcome. METHODS: Twenty-four patients with SLE were compared with 26 healthy pregnancies. vWF:Ag ...

The lupus anticoagulant (LA) and anticardiolipin antibodies (aCL) are clinically relevant because of their association with thrombosis and pregnancy loss. The group of antiphospholipid antibodies (aPL) includes antibodies primarily directed against various phospholipid-binding proteins, mainly beta2-glycoprotein I (beta2GPI) and prothrombin. Some studies suggest that there is an association between the ...

OBJECTIVES: To define a simple, safe and reliable program for the monitoring of anti-D alloimmunized pregnancies by analysis of the covariation between antenatal values of the titer and the concentration of anti-D antibodies in maternal serum, the deltaOD(450 nm) in amniotic fluid samples, and the levels of B-hemoglobin and S-bilirubin ...

Antiphospholipid antibodies are found in 15% of women with recurrent miscarriage. These women have only a 10% live birth rate in subsequent pregnancies in which no pharmacological treatment is given. Pregnancy loss is often attributable to uteroplacental insufficiency subsequent to placental thrombosis. Treatment with low dose aspirin improves the live ...

We conducted a prospective study in order to determine planned pregnancy outcome in systemic lupus erythematosus followed in a tertiary referral centre. Pregnancy was authorized if disease was inactive on 20 mg/day prednisone or less for at least 1 yr. Upon the diagnosis of pregnancy, systematic corticosteroids consisting of 10 ...

OBJECTIVE: Initial studies showed that passive immunization with human immunoglobulin G fractions containing antiphospholipid antibodies can result in murine fetal loss. We intended to use the murine model to study mechanisms of fetal loss associated with antiphospholipid antibodies. However, we have since found variable effects of antiphospholipid antibodies on murine ...

A rare case of possible glomerular thrombosis during pregnancy is reported in a patient with active systemic lupus erythematosus and the presence of anti-phospholipid antibodies.

The case notes of 20 obstetric patients with antiphospholipid syndrome delivering over a 4-year period were reviewed retrospectively. There were complete details for 22 singleton pregnancies. Obstetric complications in the pregnancies under review were frequent. Nine (47%) of the 19 women whose pregnancies reached the third trimester were delivered by ...

OBJECTIVE: To determine whether antiphospholipid antibodies other than lupus anticoagulant and anticardiolipin are associated with recurrent pregnancy loss. METHODS: Sera from three groups of women were studied: 1) 147 women with recurrent pregnancy loss but no clinical signs or symptoms of autoimmune disease who tested negative for lupus anticoagulant and ...

Antiphospholipid syndrome (APS) has been associated with recurrent pregnancy loss. The exact pathophysiologic mechanism in unclear but may be associated with an imbalance in the prostacyclin/ thromboxane ratio, which results in vasoconstriction and platelet aggregation. Antiphospholipid syndrome is diagnosed through laboratory tests and clinical assessment. Various regimens are used to ...

Autoantibodies have been known to be detected during pregnancy. The occurrence of autoantibodies during pregnancy was studied in a group of 146 healthy pregnant women from Jan-March 1995. Serum samples were tested for antinuclear (ANA), anti-ds DNA, anti-mitochondrial, anti-smooth muscle and anti-parietal cell antibodies employing the technique of indirect immunofluorescence. ...

To be sure, antiphospholipid antibody syndrome is a protean disease with many manifestations, some of which are exacerbated during pregnancy, and some of which even lead to its initial diagnosis during pregnancy. Although the best treatment during pregnancy is uncertain at this point, and some of the treatments are even ...

This article discusses the prevalence and clinical significance of antiphospholipid antibodies (aPL) in the normal, healthy pregnant population. Although an increased risk for adverse fetal outcome has been shown in a small subset of this population, most pregnancies in aPL-positive mothers have successful outcomes. We review the variations in aPL ...

Pemphigoid gestationis is an autoimmune bullous disorder affecting pregnant women which typically presents in the second and third trimester of pregnancy with an itchy bullous eruption on the abdomen and limbs. The diagnosis is confirmed by the presence of complement-binding IgG antibasement membrane zone (BMZ) antibodies, which bind to the ...

Fetal loss is increased in women who meet the Arthritis and Rheumatism Association criteria for systemic lupus erythematosus (SLE) and in women who have phospholipid antibody syndrome (APS). There are multiple causes for this fetal loss, and in patients with SLE, disease activity appears to be an important contributing factor. ...

Lupus activity during pregnancy has been the subject of much research and debate recently. Data point to increased SLE activity during pregnancy. SLE may flare during any trimester of pregnancy, as well as in the puerperium; however, flares are usually mild, affecting skin and joints, and, unless affecting the kidney, ...

Recurrent fetal wastage has been attributed to thrombosis in the antiphospholipid antibody syndrome (APAS); however, this has not been proven. Assays of coagulation activation fragments which may provide evidence for a role for thrombosis, have not been previously reported in this setting. We therefore investigated whether F1.2 levels are altered ...

The presence of lupus anticoagulant (LA) and anticardiolipin antibodies (ACA) are associated with recurring pregnancy loss. Of 387 consecutive patients investigated at a Recurring Miscarriage Clinic over a three year period, 63 (16%) were positive for LA and ACA or both. Fifty-nine patients by definition were classified as having antiphospholipid ...

BACKGROUND AND OBJECTIVES: Maternal anti-HPA alloantibodies are a rare cause of severe fetal thrombocytopenia. So far there have been no reports on the dynamics of maternal anti-HPA-5 during gestation and its effect on the fetus. MATERIALS AND METHODS: We monitored maternal anti-HPA-5b antibody titers and fetal platelet counts during gestation ...

Twelve women (13 pregnancies) with antiphospholipid antibodies (APA) who had suffered from two or more recurrent spontaneous abortions or fetal deaths and had successful pregnancy outcomes after immunosuppressive therapy were studied. APA titers were determined by enzyme-linked immunosorbent assay against cardiolipin, phosphatidyl serine and phosphatidyl inositol. Plasma levels of 6ketoprostaglandin ...

Pregnant patients with antiphospholipid syndrome (APS) may suffer from recurrent pregnancy loss, pre-eclampsia, intrauterine growth restriction and placental abruption. These conditions inevitably result in a high incidence of premature delivery with all the neonatal complications that follow. The mechanism underlying these adverse pregnancy outcomes has not yet been established. This ...

OBJECTIVE: To evaluate the effectiveness of combination therapy in preventing fetal loss in women with circulating antiphospholipid antibodies and a previous history of adverse pregnancy outcomes. STUDY DESIGN: We identified 18 pregnant women with antiphospholipid antibodies who had a total of 59 prior pregnancies. Of these pregnancies, spontaneous first-trimester abortions ...

High anti-fetal/anti-adult muscle anti-acetylcholine receptor (AChR) antibody (Ab) titer ratio is predictive of the occurrence of neonatal myasthenia gravis in a first child. The aim of the present study was to determine whether the ratio between the levels of antibodies is an intrinsic property of the mother's sera or varies ...

Complete congenital heart block (CCHB) is the most severe manifestation of neonatal lupus syndrome, associated with a mortality rate of up to 31%. It is caused by irreversible damage to the cardiac conduction system due to the transplacental passage of maternal antibodies to the fetus. Anti-Ro (SSA) and anti-La (SSB) ...

The alterations of peripheral blood lymphocyte subsets were sequentially analyzed in patients with recurrent fetal wastage who were treated with the Chinese herbal medicine, Sairei-to (Chan ling-Tan) for positive antiphospholipid antibodies to analyze the underlying mechanisms of the therapy. The titer of antiphospholipid antibodies was significantly decreased by administration of ...

Recurrent fetal losses indicate screening for antiphospholipid antibodies, especially after the third consecutive fetal loss, or when they occur after 12 weeks gestation or when the mother presents with thrombosis or other ailments of antiphospholipid syndrome. Fetal loss may be caused by thromboses of placental vasculature. There is no agreement ...
