Antiphospholipid antibodies, notably the lupus anticoagulant and anticardiolipin antibodies, are associated with recurrent fetal wastage, pregnancy complications, and thromboses. Aggressive medical treatment using aspirin and steroids has been recommended. Fifty-one patients with antiphospholipid antibodies, only four with underlying connective tissue disorders, were followed through 53 pregnancies. Aggressive therapy was used in 33 pregnancies, 90.9% of which resulted in successful obstetric outcomes, a highly statistically significant difference compared with previous pregnancies in the same patients. Most pregnancies among nine patients receiving single-agent therapy (aspirin or steroids alone) and eight patients not treated also had successful outcomes. A 48.6% complication rate was found in association with therapy, particularly gestational diabetes mellitus. There was no statistical correlation between dose or duration of therapy and development of treatment-related complications. Although a subgroup of patients with antiphospholipid antibodies will benefit from aggressive therapy, the high complication rate warrants close observation.

Gestational diabetes resistant to insulin therapy occurring in association with insulin receptor antibodies has not been reported previously. A patient developed diabetes mellitus at 21 weeks' gestational age and had a previous history of thrombotic thrombocytopenia purpura, then in remission. She developed life-threatening diabetic ketoacidosis that was severely resistant to insulin treatment despite the usage of adjunct therapy, including plasmapheresis, and intravenous cyclophosphamide and steroids. She also had lupus nephropathy. Termination of the pregnancy at 22 weeks' gestation resulted in a rapid resolution of both the diabetes and lupus nephropathy.

Among 4380 children born in 1987-1997 of women with a diagnosis of diabetes and alive at the age of one, 10 were registered in the Swedish Cancer Registry before the end of 1998. The odds ratio for having a childhood cancer after maternal diabetes, stratified for year of birth, maternal age, parity, multiple birth, and 500 g birth weight class was 2.25 (95%CI 1.22-4.15). Among 5842 children born during the period 1973-1997 whose mothers had other auto-immune diseases (SLE, rheumatoid arthritis, Crohn, ulcerous colitis, multiple sclerosis or thyroiditis), the number of observed childhood cancers (9) was close to that expected (8.5). Maternal diabetes but not other auto-immune diseases may be a risk factor for childhood cancer.

This study compares pregnancy outcomes in systemic lupus erythematosus (SLE) patients post renal transplant with recipients with other primary diagnoses, utilizing data from the National Transplantation Pregnancy Registry, Philadelphia, PA. Recipients were referred from transplant centers nationwide. A retrospective analysis was performed using data from questionnaires, hospital records and telephone interviews. Outcomes of pregnancies post renal transplant secondary to lupus nephritis (SLE: n = 38; 60 pregnancies) were compared with the pregnancy outcomes of renal recipients with other diagnoses (non-SLE: n = 247; 374 pregnancies). Drug-treated hypertension during pregnancy was less common in the SLE group than in the non-SLE group (45.0% vs. 62.5%, p = 0.015). There were fewer cesarean sections in the SLE group (30.2 vs. 53.2%, p = 0.008). There was no primary or gestational diabetes in the SLE group. There were no other statistical differences in maternal conditions or pregnancy outcomes between the SLE and non-SLE groups, or in the incidence of post pregnancy graft loss. Female recipients transplanted for renal failure secondary to lupus nephritis can successfully maintain pregnancy. Outcomes are comparable to renal recipients with other diagnoses. Newborns in both groups were often premature and had low birthweight. Overall childhood health was reported to be good; there were no apparent predominant structural malformations among the children.

Neonatal hemochromatosis is an enigmatic disease. Little is known about iron metabolism in this disease, including the tissue concentration of ferritin or its H and L subunit ratio. The authors report the tissue iron, ferritin, and ferritin subunit content of a child who died at 5 weeks of neonatal hemochromatosis. The child was born at 29 weeks gestation to a mother with lupus, sickle cell trait, and gestational diabetes. The child's severe liver dysfunction led to the clinical diagnosis of neonatal hemochromatosis at 1 week of age. Despite aggressive support, including red cell transfusions and chelation, the child died of an intracranial hemorrhage. Autopsy showed liver fibrosis and iron staining characteristic of neonatal hemochromatosis. Autopsy liver tissue was compared to age-matched control tissue. Soluble protein was analyzed by the Bradford method. Soluble iron (over 90% of total iron) was analyzed by the o-phenanthroline complex. Tissue ferritin and human ferritin controls (Calzyme) were analyzed by Western blotting after SDS-PAGE, identified with sheep anti-human ferritin antibodies (The BindingSite) secondary antibody-fluorescence for detection, and quantified using the Molecular Dynamics Storm 840 phosphorimager and ImageQuant software. Protein, iron, and total ferritin were similar in the normal and neonatal hemochromatosis liver tissues. Ferritin subunits, however, showed an increased H/L-subunit ratio compared to an age-matched control. This first report of a marked increase in the ferritin H/L-subunit ratio may point to an underlying mechanism of disease in this enigmatic disorder.

The NTPR maintains an ongoing database to study the outcomes of pregnancies in female transplant recipients as well as those pregnancies fathered by male transplant recipients. Recipients are entered into the database by completing. a single page questionnaire. There is steady follow-up of recipients and their offspring. While the majority of pregnancy outcomes have occurred in kidney recipients, data continue to accrue in the other types of organ recipients. KIDNEY: A small percentage of pregnancies in female kidney recipients are complicated by rejection with poorer outcomes with respect to both maternal graft function and their newborn. Other analyses this year focused on outcomes of recipients with systemic lupus erythematosus and those with multiple gestations. It was observed that recipients with systemic lupus erythematosus were able to maintain a pregnancy with outcomes that appear to be similar to other diagnoses. In an analysis of multiple gestations in female kidney recipients maintained on calcineurin inhibitors, no multiple gestations higher than triplets have been reported to the NTPR. Successful outcomes have been noted among these recipients. This does require continued surveillance, as there has been an increase in the number of multiple gestations in the general population with the use of adjunctive technologies. OTHER ORGANS: In analyzing outcomes in female liver recipients, no specific graft or newborn outcome differences have been noted when a comparison has been made between different caicineurin inhibitor regimens. Pregnancies in female pancreas-kidney recipients appear to be tolerated with respect to pancreas graft function with no diagnoses of gestational diabetes reported to the NTPR. Data continue to accrue among thoracic recipients. Poorer maternal survival postpartum in lung recipients may be related to higher risks inherent in this population and requires further experience and investigation. OTHER ISSUES: With the recent proliferation of newer immunosuppressive agents, a question that is raised is whether a regimen can be specifically designed with recipients of childbearing age in mind. Extensive data published on azathioprine and cyclosporine treated recipients suggests that while there is a pattern of prematurity among the newborn there has not been an increase in the incidence or pattern of specific malformations noted among the newborn. Less assurance can be given with newer agents such as sirolimus and MMF. Calcineurin inhibitor minimization or steroid withdrawal would require that other agents with less reproductive information be implemented. The unknown risk of teratogenicity must be balanced against the potential risk of rejection or graft dysfunction when deciding which agent to use during pregnancy. Through each of the organ recipient groups, there are sporadic cases of rejection, graft dysfunction, and graft deterioration. Birth defect patterns have not appeared to be specific to any specific regimen as yet. Two newborns with malformations have been noted among a limited series with MMF exposure, but other factors may also be at play. The use of MMF during pregnancy continues to be an unresolved issue in the transplant community. As yet, no one regimen has been identified as superior to another for use during pregnancy. Continued surveillance with the newer agents is necessary. Investigators have taken differing views regarding the safety of breastfeeding in the transplant recipient population, especially with regard to drug exposure to the infant. This issue remains unresolved and some transplant recipient mothers have chosen to breastfeed. Other factors for consideration are the potential long-term effects on offspring of transplant recipients. While there may not be specific structural defects noted at birth, more subtle effects on either immunologic or reproductive function may not manifest until later in life. Scott and his group in Utah have raised this issue with a case report and have initiated a study to focus on the next generation. The safety of pregnancy for parent and child remain the goals of the NTPR. Continued entries to the registry, especially in light of newer combinations of immunosuppressive agents, should assist in developing guidelines needed for management in this era of expanding immunosuppressive agents. All centers are encouraged to participate.

Considerable experimental and clinical data indicate that sex has an important influence on cardiovascular physiology and pathology. This report integrates selected literature with new data from the Women's Ischemia Syndrome Evaluation (WISE) on vascular findings in women with ischemic heart disease (IHD) and how these findings differ from those in men. A number of common vascular disease-related conditions are either unique to (e.g., hypertensive disorders of pregnancy, gestational diabetes, peripartum dissection, polycystic ovarian syndrome, etc.) or more frequent (e.g., migraine, coronary spasm, lupus, vasculitis, Raynaud's phenomenon, etc.) in women than men. Post-menopausal women more frequently have many traditional vascular disease risk conditions (e.g., hypertension, diabetes, obesity, inactivity, and so on), and these conditions cluster more frequently in them than men. Considerable evidence supports the notion that, with these requisite conditions, women develop a more severe or somewhat different form of vascular disease than men. Structurally, women's coronary vessels are smaller in size and appear to contain more diffuse atherosclerosis, their aortas are stiffer (fibrosis, remodeling, and so on), and their microvessels appear to be more frequently dysfunctional compared with men. Functionally, women's vessels frequently show impaired vasodilator responses. Limitations of existing data and higher risks in women with acute myocardial infarction, need for revascularization, or heart failure create uncertainty about management. A better understanding of these findings should provide direction for new algorithms to improve management of the vasculopathy underlying IHD in women.

We examined 62 women with three or more recurrent adverse pregnancy outcomes where we excluded the other well known causes of this state. We detected lupus anticoagulant (LAC) in three (5%), with the use of set of coagulation tests: activated partial thromboplastin time (APTT), APTT ratio, kaolin clotting time ratio (KCT), APTT of the 50:50 mixture of the patients and control plasmas, APTT ratio of the 50:50 mixture, phospholipid correction test and heat stability test. We excluded connective tissue disorders. Therapy was started between 12th and 14th gestational week. Efficacy was monitored in intervals of 2-6 weeks with following tests: APTT ratio, KCT and plateled count. Patient A, with strong LAC activity and thrombocytophenia, reacted weakly to therapy with Pronison 40 mg/day and Aspirin 80 mg/day. The activity of LAC was slightly diminished but was present all the time. Patient expressed hypertension and gestational diabetes mellitus. The outcome of pregnancy was adverse and placenta had typical pathological changes. Patient B, with moderate LAC activity, reacted quickly and completly on therapy with Pronison 20-40 mg/day and Aspirin 80 mg/day. The course of pregnancy was regular. The outcome was successful and placenta had no pathological changes. Patient C, with mild LAC activity, was treated only with Aspirin 80 mg/day. LAC activity rapidly disappeared, the course of pregnancy was regular and outcome was successful. On the basis of the first results we concluded that applied set of tests was sensitive for LAC of different intensity and that dissapeparance of LAC activity with the use of therapy anticipates successful pregnancy outcome.

There appears to be an incompressible high rate of preterm births among populations of African origin irrespective of their geographic location. The objective of this study was to assess the risk factors for preterm birth in a French Caribbean population of African descent, offered medical care comparable to that on the French mainland, but presenting a higher rate of preterm birth. The study was based on a birth cohort at maternity hospitals in Guadeloupe (French West Indies) including 911 singleton pregnancies enrolled during their third trimester check-up visits. Associations between risk factors and the risk of preterm delivery (spontaneous and induced) were assessed using a multivariate Cox model. In addition, prevalences of sociodemographic and medical factors in Guadeloupe were compared with those on the French mainland. 144 women (15.8 %) delivered preterm, medically induced in 52 %. Women delivering preterm were more often over 35 years old (37 %), single (54 %), and had higher prevalence of prior preterm birth (20 %), prior miscarriage (37 %), lupus (3 %), asthma (14 %), gestational hypertension (26 %), gestational diabetes (13 %) and urinary tract infection (24 %) than women with term births. In the whole cohort, these risk factors were also more frequent than in mainland France. Our results suggest highly prevalent medical risk factors for preterm births in Guadeloupe. This observation combined with specific social risk factors (older maternal age, single living) less frequent on the French mainland probably explains a large part of a higher prevalence of preterm births in this population despite similar medical provision.
