Effect of indomethacin on individual amniotic fluid indices in multiple gestations.

To determine the effect of indomethacin on the amniotic fluid index of individual fetuses in multiple gestations, we evaluated seven sets of twins and two sets of triplets in preterm labor (eight cases) or with polyhydramnios (one case). The dose of oral indomethacin was either 25 mg every 12 hours or 25 mg every 6 hours. The amniotic fluid volume of individual amniotic sacs was estimated serially by the amniotic fluid index. When an oral dose of indomethacin of 25 mg every 6 hours was used, oligohydramnios eventually occurred in five of eight amniotic sacs and a subjective decrease in amniotic fluid occurred in one sac. Oligohydramnios was detected in only one of 13 amniotic sacs when the dose of indomethacin was 25 mg every 12 hours. The amniotic fluid volume returned to normal in these seven amniotic sacs within 4 days of discontinuing indomethacin. We conclude that maternal indomethacin therapy has a variable effect on the individual amniotic fluid volumes in multiple gestations.

The association between polyhydramnios and preterm delivery.

OBJECTIVE: To determine whether an association exists between the severity of polyhydramnios and the frequency of preterm delivery. METHODS: The study group consisted of 275 singleton pregnancies with polyhydramnios as defined by an amniotic fluid index (AFI) of at least 25 cm. Polyhydramnios was arbitrarily categorized into three groups by severity: mild (AFI 25-30 cm), moderate (AFI 30.1-35 cm), and severe (AFI greater than 35.1 cm). A delivery was considered preterm if it occurred before 37 weeks' gestation. RESULTS: Fifty-two of 275 (18.9%) women delivered before 37 weeks' gestation. Preterm delivery occurred in 37 of 199 (18.5%) cases with mild polyhydramnios, 12 of 55 (21.8%) with moderate polyhydramnios, and three of 21 (14.3%) with severe polyhydramnios (no statistically significant difference). Fetuses with congenital malformations (16 of 41, 39%) and those of diabetic mothers (ten of 45, 22.2%) had a significantly higher incidence of preterm delivery than did cases with unexplained polyhydramnios (24 of 190, 12.6%; P < .001). The prematurity rate in cases with idiopathic polyhydramnios was no higher than the overall rate for our hospital. CONCLUSION: The underlying cause of polyhydramnios, rather than the relative excess of amniotic fluid as defined by this study, appears to determine when preterm labor will occur.

Resolving polyhydramnios: clinical significance and subsequent neonatal outcome.

The objective of this study was to determine the clinical significance and neonatal outcome of patients with polyhydramnios that subsequently resolved prior to delivery. A retrospective review of 275 cases of polyhydramnios, defined as an amniotic fluid index of > or = 25.0 cm, identified 41 cases in which the amniotic fluid volume returned to normal prior to delivery. A total of 40 out of 41 patients with resolving polyhydramnios had a mild to moderate excess of amniotic fluid. There was a significant difference in the distribution of neonatal delivery weights between the study group and a matched control group. Twelve of 41 (29.3%) neonates from the study vs. none of the neonates in the control group were large for gestational age (p < 0.001). A total of 21 of 41 patients (51.2%) in the study group vs. three of 41 (7.3%) patients in the control group had at least minimal glucose intolerance (p < 0.01). We conclude that patients with resolving polyhydramnios have a significantly higher prevalence of glucose intolerance and fetal macrosomia than patients with normal pregnancies.

Interferon-alpha-2b with VMCP for induction in multiple myeloma: the Israel Myeloma Cooperative Group experience.

In 1988, a prospective, randomized multicenter study was initiated to determine the efficacy of a combined induction regimen with recombinant interferon-alpha-2b (IFN-alpha) and maintenance with IFN-alpha on the response and survival rates in multiple myeloma (MM) patients. Induction therapy consisted of VMCP (vincristine, melphalan, cyclophosphamide, prednisone), randomized to combine IFN-alpha at a dose of 2 x 10(6) U, 5 days per week throughout the induction period of 12 months. Patients who achieved plateau phase were subsequently randomized again between IFN alpha maintenance (2 x 10(6) U, 3 days a week) for 12 months and no maintenance therapy. Of the previously untreated patients, 84 were initially randomized for induction therapy, and 31 for the maintenance phase with IFN-alpha. Results of the cohort median survival, based on the intention to treat, have shown that those on the VMCP/IFN-alpha arm had a median survival of 53 months, compared with patients on the VMCP induction arm who a median survival of 26 months (P = 0.052). The median survival of stage 3 evaluable patients who were on the VMCP/IFN induction arm was 43 months, and 13 months for patients treated by VMCP alone (P = 0.008). No significant difference in survival was detected among patients in partial remission (after induction) who had a second IFN-alpha randomization at the plateau phase. Hematologic toxicity, mild to moderate fever, and fatigue were more common in the VMCP/IFN induction arm. The results show that VMCP/IFN is a well-tolerated treatment regimen, and is superior to VMCP for patients with stage 3 myeloma.

Anti-DNA antibodies secreted by peripheral B cells of lupus patients have both normal and lupus-specific features.

Autoantibodies present in sera of patients with systemic lupus erythematosus (SLE) are found in low titer in sera of healthy individuals. Hence, it is possible that B cell populations in SLE patients and in normal individuals are homologous and in the absence of regulatory forces would secrete similar antibodies. We therefore studied antibody secretion of Epstein-Barr virus-transformed B cells of 20 SLE patients and 20 healthy subjects. Normal and lupus antibody repertoires did not differ significantly with respect to antigenic specificities, isotype, avidity, and titer. However, anti-DNA antibodies bearing the anti-DNA-associated idiotype 8.12 were found only in SLE. These findings suggest that the B cell repertoire of SLE and normal individuals is more similar than the serum antibody profile. However, part of the anti-DNA response in SLE probably reflects affinity (antigen driven) maturation as it differs in idiotype profile from anti-DNA response of normal individuals.

Lupus anticoagulant. Significance in habitual first-trimester abortion.

Therapy with steroids and aspirin has been reported to benefit pregnancies in patients with lupus anticoagulant (LA). In this study, habitual first-trimester aborters with LA using steroids and aspirin were compared to a control group of untreated habitual aborters without LA. In habitual aborters with LA, 12 of 24 (50%) pregnancies reached the second trimester as compared to 8 of 22 pregnancies (36%) in the control group. Since the treated group did no better than the control group, LA probably is not a cause of first-trimester abortion. However, once the second trimester is reached, a 50% incidence of growth retardation was found, and 42% of fetuses died in the second or third trimester in treated LA patients. Treatment with steroids and anti-platelet aggregating agents may be necessary despite the attendant risks to prevent those sequelae in the second and third trimesters. There was a 29% live birth rate in treated LA patients; the rate was 36% in control patients. However, this rate was produced only by early intervention, which was unnecessary in the control patients.

Successful pregnancy outcome with combination therapy in women with the antiphospholipid antibody syndrome.

Four women with the antiphospholipid syndrome associated with lupus anticoagulant and a poor obstetric history were treated with a combination of glucocorticosteroids, anticoagulants and platelet inhibitor therapy. All patients had at least one previous miscarriage while receiving prednisone and low-dose aspirin. The treatment regimen included: aspirin, dipyridamole, prednisone, and warfarin or heparin. This treatment resulted in a successful pregnancy outcome in all cases, without preeclampsia or recurrence of thrombosis. One patient developed a vertebral compression fracture while receiving heparin and prednisone. Two pregnancies required cesarean delivery for fetal distress at 32 and 34 weeks. All four infant birth weights were appropriate for the gestational age. This regimen may be a therapeutic option for patients with the antiphospholipid antibody syndrome, especially if they have failed other commonly used treatments.

Lupus anti-DNA antibodies bearing the 8.12 idiotype appear to be somatically mutated.

Anti-DNA antibodies in systemic lupus erythematosus (SLE) sera were analyzed using an antiidiotype designated 8.12 which recognizes a determinant on lambda light chains highly expressed in SLE sera. Eight of ten normal individuals had peripheral blood lymphocytes which produced high-titered 8.12-positive antibodies, following transformation with Epstein Barr virus, implying that the 8.12-reactive sequence originates in the germline gene (GLG). Of 58 SLE sera, 32 contained elevated titers of 8.12-reactive antibodies. Twenty-three of these sera had 8.12-reactive anti-DNA antibodies, suggesting a strong correlation between 8.12 idiotype and DNA binding. Moreover, 20 of 26 8.12-reactive IgG antibodies and only 4 of 10 8.12-reactive IgM antibodies bound DNA (P less than 0.05). These observations strengthen our previous findings in myeloma sera that DNA binding is associated with IgG isotype in the 8.12 idiotype system and suggest that the acquisition of anti-DNA reactivity in antibodies bearing the GLG idiotype 8.12 is achieved by somatic mutation, a feature of an antigen-driven response.

Superior vena cava occlusion in a patient with antiphospholipid antibody syndrome.

A 55-year-old woman with a lupus like disease, associated with the lupus anticoagulant, was admitted because of facial edema. Her facial swelling was previously attributed to the steroids she had been taking and they were tapered without improvement. Laboratory tests revealed high titers of anticardiolipin antibodies. Computerized tomography of her chest and Doppler ultrasound examination of her neck veins demonstrated a thrombus in the superior vena cava. She was treated with heparin and was maintained with longterm warfarin therapy with uneventful followup. Superior vena cava obstruction should be added to the long list of thromboembolic complications of the antiphospholipid syndrome.

Fetal demise associated with lupus anticoagulant: clinical features and results of treatment.

There are many reports in the literature associating lupus anticoagulant with fetal death. Successful pregnancies have been reported following suppression of the antibody by prednisone and the addition of antiaggregants and possibly anticoagulants. This report describes our experience treating such patients and the outcome of subsequent pregnancies. The results are less successful than the figures in the literature, 13 live births out of 27 pregnancies in 19 patients. This may be due to lupus anticoagulant being diagnosed as the cause for a wide variety of clinical presentations including habitual first trimester abortion, mid trimester fetal death, intrauterine growth retardation and placental dysfunction in the third trimester. Our experience shows that steroids and antiaggregants have a definite place in cases of second and third trimester fetal death and in cases of clinical systemic lupus erythematosus. However, lupus anticoagulant is one of a spectrum of autoantibodies whose pathophysiology has not been fully elucidated. It is questionable whether this regimen of treatment has a place in patients with no previous fetal loss or in cases of primary habitual abortion.
