OBJECTIVE: To determine whether plasma and peritoneal fluid levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) are altered in women with ovarian hyperstimulation syndrome (OHSS). DESIGN: Prospective, case-control study. SETTING: Lis Maternity Hospital and the Sara Racine IVF Unit, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel. PATIENT(S): The study group comprised 16 women with severe OHSS. The control groups comprised 10 women treated with controlled ovarian hyperstimulation and 8 women with normal findings at diagnostic laparoscopy. INTERVENTION(S): Plasma samples were obtained from the study group and the first control group. Peritoneal fluid samples were obtained during paracentesis from the study group and during diagnostic laparoscopy from the second control group. MAIN OUTCOME MEASURE(S): Samples were assayed by specific ELISA for sVCAM-1 and sICAM-1. RESULT(S): The mean peritoneal fluid levels of sVCAM-1 and sICAM-1 and the mean plasma levels of sVCAM-1 were significantly higher in the women with OHSS than in the control groups. However, the mean plasma levels of sICAM-1 were comparable. A positive correlation was demonstrated between the levels of sVCAM-1 and plasma E2 at the time of hCG administration and between the levels of sICAM-1 and number of ova retrieved. CONCLUSION(S): Our findings suggest that soluble cell adhesion molecules may have a role in the pathogenesis and progression of OHSS.
OBJECTIVE: To evaluate the outcome of IVF in patients with stages III and IV endometriosis. DESIGN: Retrospective study. SETTING: The Sara Racine IVF Unit, Lis Maternity Hospital, Tel Aviv Sourasky Medical Center, Israel. PATIENT(S): Fifty-eight patients with stages III and IV endometriosis and 60 patients with tubal infertility. INTERVENTION(S): IVF-ET for all couples. MAIN OUTCOME MEASURE(S): Fertilization, pregnancy, and birth rates. RESULT(S): The comparison between patients with endometriosis and those with tubal infertility indicated that the former had a poor IVF outcome in terms of reduced fertilization rate (40% vs. 70%), reduced pregnancy rate per cycle (10.6% vs. 22.4%), and reduced birth rate per cycle (6.7% vs. 16.6%). The differences were statistically significant. CONCLUSION(S): The results show an unfavorable outcome of IVF-ET in patients with endometriosis when compared with those who have tubal infertility.
OBJECTIVE: To determine serum levels of vascular endothelial growth factor (VEGF) and evaluate their capacity to serve as a marker for the diagnosis of ectopic pregnancy (EP). DESIGN: Prospective, case-controlled study. SETTING: A tertiary care center. PATIENT(S): Twenty women with EP, 10 women with normal intrauterine pregnancy, and 10 women with abnormal intrauterine pregnancy, all at comparable stages of gestation. INTERVENTION(S): Serum samples were obtained from all women. MAIN OUTCOME MEASURE(S): All samples were analyzed for VEGF, progesterone, and beta-hCG by specific methods. RESULT(S): Women with EP had higher serum levels of VEGF than women with normal intrauterine pregnancy and women with abnormal intrauterine pregnancy (median levels, 226.8 pg/mL, 24.4 pg/mL, and 59.4 pg/mL, respectively). With a cutoff level of 200 pg/mL, serum VEGF could distinguish intrauterine from extrauterine pregnancy with a sensitivity of 60%, specificity of 90%, and positive predictive value of 86%. CONCLUSION(S): The increased serum VEGF levels in women with EP may facilitate this challenging diagnosis and reduce maternal morbidity and mortality.
OBJECTIVES: The aim of the study was to investigate the process of glycolysis in gonadotropic, hyperstimulated, human ovarian follicles. STUDY DESIGN: Follicular fluid (FF) lactate and glucose concentrations were measured in 26 patients with tubal factor infertility undergoing in vitro fertilization treatment. RESULTS: The mean FF lactate and glucose concentrations were 3.17+/-0.90 mM with positive, and 3.39+/-0.91 mM with negative correlations to follicular size. FF lactate concentration correlated negatively to glucose levels. CONCLUSIONS: Our study confirms in vivo the anaerobic glycolysis in gonadotropic, hyperstimulated human ovarian follicles.
The membranes of human spermatozoa contain an extremely high concentration of polyunsaturated fatty acids and are therefore susceptible to lipid peroxidation damage. The aim of this study was to retrospectively determine the association between the lipid peroxidation levels of washed spermatozoa, as indicated by thiobarbituric-acid-reactive substance concentration, and: (a) semen quality evaluated by basic routine, biochemical, cytological and quantitative ultramorphological analyses; (b) IVF fertilization rate. Semen samples from 45 male partners of couples who had been referred for IVF treatment due to a female infertility factor were evaluated for quality as well as for thiobarbituric-acid-reactive substance concentrations. The latter were found to have a negative correlation with total sperm count, semen volume, zinc/fructose ratio, and the integrity of sperm acrosome and axonema. It was suggested that lipid peroxidation has a deleterious effect on the ultramorphological status of the sperm cells and, thereby, on the male fertilization potential. The content of the seminal fluid, about 30% of which is produced by the prostate, may protect spermatozoa from this destructive process. A negative correlation was also found between thiobarbituric-acid-reactive substance concentrations and IVF fertilization rate. When the patients were subdivided into fertilizing (fertilization rate > 0%) and nonfertilizing (fertilization rate = 0%) subgroups (n = 33 and n = 12, respectively), the former exhibited significantly lower thiobarbituric-acid-reactive substance concentrations than the latter. A new IVF fertilization index based on the lipid peroxidation level was established. This index had a predictive power of 93% (94% sensitivity and 92% specificity). The clinical value of this index should be further verified.
The study was conducted to investigate the association of placental morphological and histopathological features with term, singleton pregnancies obtained by assisted reproductive technologies (ART). The study group comprised 45 consecutive women with a singleton pregnancy, obtained by ART, who delivered at term. For each subject in the study group, the consecutive, matched-for-age-and-parity woman, with a term singleton, spontaneously conceived pregnancy served as the controls. The placentae of both groups were subject to a detailed morphological and histopathological investigation by one pathologist, who was blinded to specimen origin. Pregnancy complications, fetal weight and perinatal outcome were similar in both groups. No differences in morphological or histopathological features of the placenta were observed between the groups. Nevertheless, the placentae of the study group showed a borderline, significantly higher placental weight and placental:fetal weight ratio, and placental thickness was significantly higher. Abnormal umbilical cord insertion was significantly more prevalent in the study group. Neither the specific ART method employed, nor the infertility factor affected the results, suggesting that multiple embryo transfers and/or ovulation induction protocols may account for these differences.
PROBLEM: The study was conducted to investigate the possible role of circulating ovarian autoantibodies (ov-ab) in patients with repeated in vitro fertilization embryo transfer (IVF-ET) failure and to evaluate the effectiveness of immunosuppression treatment in these patients. METHOD OF STUDY: The study group comprised 80 IVF patients who had five or more failed treatment cycles (mean 10.2; range 7-22). The presence of ov-ab was compared between these women and 1) 50 IVF patients who conceived during the first three treatment cycles; 2) 50 healthy nulligravidae. All participants were seronegative to nonorgan-specific and antithyroid autoantibodies. Patients in the study group who were positive for ov-ab were treated with 10 mg/day prednisone starting 1 month before ovulation induction. Embryo grading was compared in the IVF cycles before and after treatment. RESULTS: Ov-ab were found in ten patients (12.5%) in the study group, compared to none in the control groups (P = 0.01). Nine of the patients positive for ov-ab were treated with prednisone for their following cycle. A statistically significant improvement in embryo grading was noted. Three patients conceived after treatment (33%), with a take-home baby rate of 22%, compared to only six patients (8.6%) who conceived among the rest of the seronegative study group, with a take-home baby rate of 7.1% (P = 0.05). CONCLUSIONS: Ov-ab are a possible marker of an autoimmune disorder that may be one of the causes of repeated IVF failures. Immunosuppression treatment may prove efficient in ov-ab seropositive patients with repeated IVF failures by improving embryo grading and pregnancy rate.
PROBLEM: The study was conducted to determine whether altered plasma levels of soluble intercellular adhesion molecule (ICAM)-1 and soluble vascular cell adhesion molecule (VCAM)-1 are involved in the pathogenesis of preeclampsia. METHOD OF STUDY: Maternal plasma samples were collected from 20 patients with preeclampsia, 20 matched normotensive patients with uncomplicated pregnancies. and ten healthy nonpregnant women. Samples were assayed for soluble VCAM-1 and soluble ICAM-1 by specific enzyme-linked immunosorbent assay. RESULTS: Both soluble VCAM-1 and soluble ICAM-1 were detectable in the plasma of all preeclamptic, normotensive pregnant, and nonpregnant women. The mean plasma level of soluble VCAM-1 was significantly higher in preeclamptic women compared to normotensive pregnant women (1831 ng/mL +/- 534 ng/mL vs. 1254 ng/mL +/- 386 ng/mL, respectively; P < 0.05). However, the plasma level of soluble VCAM-1 was unchanged during the third-trimester of normal pregnancy compared to nonpregnant women. The mean plasma level of soluble ICAM-1 in preeclamptic and normotensive pregnant women were increased when compared to nonpregnant women. However, the mean plasma level of soluble ICAM-1 was comparable in women with preeclampsia and normotensive pregnancy. CONCLUSIONS: The selective increased plasma levels of soluble VCAM-1 in patients with preeclampsia provide evidence for endothelial activation and suggest distinct pathways for neutrophil and endothelial activation in preeclampsia.
OBJECTIVE: To determine the possible predictive role of vascular endothelial growth factor (VEGF) levels in the follicular fluid (FF) at the time of oocyte retrieval in the development of ovarian hyperstimulation syndrome (OHSS) and its possible origin. STUDY DESIGN: FF was obtained from 174 high-responder patients at the time of oocyte retrieval. The study group comprised 16 high-responder patients who developed early, severe OHSS and from whom serum and peritoneal fluid (PF) were obtained during the active phase of the syndrome. These women were compared to 16 high-responder patients who did not develop OHSS. An additional control group comprised 16 low-responder patients who also did not develop OHSS. The FF, serum and PF samples were tested for VEGF by enzymelined immunosorbent assay. RESULTS: No differences in the FF VEGF levels were found among the OHSS group (1,742.3 +/- 522.4 pg/mL), the high-responder group that did not develop OHSS (1,802.0 +/- 584.3 pg/mL) and the low-responder group (1,686.7 +/- 374.2 pg/mL). In the OHSS group, no differences were found between the serum and PF VEGF levels (247.3 +/- 31.4 and 642.9 +/- 328.3 pg/mL, respectively). No correlation was found between the FF concentrations of VEGF and the mean serum 17-beta estradiol levels or number of oocytes retrieved. CONCLUSION: We conclude that preovulatory FF levels should not serve as a possible predictive factor for development of OHSS. The increased capillary permeability found in OHSS may be due to its systemic effect.

OBJECTIVE: To investigate the possible role of multifetal pregnancy reduction as a risk factor for the development of periventricular leukomalacia, which has been associated with prematurity and twin pregnancies. DESIGN: A case-control study. SETTING: In Vitro Fertilization Unit and Intensive Care Nursery of the Tel Aviv Sourasky Medical Center, Tel Aviv, Israel. PATIENT(S): A total of 1,401 consecutive preterm infants who were born between January 1, 1994, and December 31, 1995. INTERVENTION(S): Cranial ultrasonographic evaluation of each infant within 3 days of birth. MAIN OUTCOME MEASURE(S): Premature infants who developed periventricular leukomalacia (cases) were compared with premature infants who did not develop this disorder (controls) when multifetal pregnancy reduction was considered. RESULT(S): Fourteen premature infants developed periventricular leukomalacia. Of these, 28.6% (4 infants) were exposed to multifetal pregnancy reduction, compared with 1.9% of the controls, giving an odds ratio (OR) of 20.9 (95% confidence interval [CI] 5.5-79.4). Adjustment of this OR for IVF treatment (OR, 18.6; 95% CI, 1.8-140.3), twinning (OR, 6.3; 95% CI, 1.3-30.3), and for both IVF treatment and twinning simultaneously (OR, 8.5; 95% CI, 1.7-42.2) did not explain all the observed associations between periventricular leukomalacia and multifetal pregnancy reduction. CONCLUSION(S): Our data suggest that multifetal pregnancy reduction may be an additional risk factor for periventricular leukomalacia among premature infants, regardless of twinning.

The aim of our study was to evaluate the pregnancy outcomes of late selective multifetal reduction (MFPR). We performed a 3 year, prospectively-designed study in which 28 patients underwent MFPR at a mean gestational age of 20.2 +/- 3.9 weeks (range 14-29 weeks). The indications for MFPR included: multiple gestation (> or = 3) (57%), structural anomaly (29%), and chromosomal abnormality (14%). The procedure was performed using ultrasonographically-guided intracardiac injection of potassium chloride. The mean gestational age at delivery was 36.6 +/- 2.2 weeks (range 31-40 weeks). Nine patients (32%) delivered before 36 weeks of gestation. The mean birth weight was 2370 +/- 614 g (range 1510-3250 g). Discordancy was evident in four twins (14%), and intrauterine growth retardation in four pregnancies. One case (3.5%) presented with oligohydramnios, and one with pregnancy-induced hypertension. One case of late abortion due to passive cervical dilatation 4 weeks after the MFPR was observed. Procedure-related amnionitis followed by late abortion occurred in one case. A total of 57% of the patients delivered vaginally and 43% delivered by Caesarean section. We concluded that late selective MFPR is associated with favourable perinatal outcome. Late MFPR may facilitate the detection of structural and chromosomal anomalies prior to the procedure, and the accomplishment of selective reduction of the affected fetus.

PROBLEM: Recently, it has been suggested that anticardiolipin antibodies (ACAs) may serve as possible markers for reproductive failure. The association between ACAs and embryo morphology in patients undergoing in vitro fertilization (IVF) was investigated. METHOD OF STUDY: This prospective study comprised 117 patients with either tubal factor or unexplained infertility. Embryo morphology was blindly scored from I to IV according to blastomere regularity and the presence of fragments. Anticardiolipin antibodies (immunoglobulin [Ig] G and IgM) were detected. RESULTS: Anticardiolipin antibodies were found in 26 (50%) of the 52 patients with abnormal morphology, compared with 13 (20%) of the 65 patients with normal embryo morphology (P = 0.001). No statistically significant differences were found between the prevalence of ACAs among patients with tubal factor and those with unexplained infertility (29.6% and 36.5%, respectively). CONCLUSIONS: Our study shows an association between embryo morphology and the presence of ACAs. This association may explain the low implantation rate and early pregnancy loss in patients with ACAs.
OBJECTIVE: To assess the relationship between tumor marker carcinoma antigen-125 levels in seminal plasma and serum and fertilization rates in an IVF program, using intracytoplasmic sperm injection (ICSI). DESIGN: A prospective study. SETTING: IVF Unit, Lis Maternity Hospital, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel. PATIENT(S): Twenty-five infertile patients with severe oligo-terato-asthenospermia syndrome and 25 fertile male donors. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Serum and seminal plasma carcinoma antigen-125 concentrations and fertilization rate per cycle. RESULT(S): In the infertile group, the seminal plasma carcinoma antigen-125 levels ranged from 22.0 to 1,284.0 U/mL (mean level +/- SD, 229.9 +/- 274.2 U/mL). In the normospermic fertile male donors, the seminal plasma carcinoma antigen-125 concentrations ranged from 12.2 to 336.7 U/mL (mean level +/- SD, 110.1 +/- 91.6 U/mL). This difference was statistically significant. The mean +/- SD ratio between the seminal plasma/serum carcinoma antigen-125 levels differed significantly between the infertile group (47.9 +/- 61.3) and the fertile male donors (5.7 +/- 3.5). In the infertile group, the ratio between the seminal plasma/serum carcinoma antigen-125 levels was found to be negatively correlated with the oocyte fertilization rate. CONCLUSION(S): The ratio between carcinoma antigen-125 levels in the seminal plasma and serum may be an indirect marker for male infertility and fertilization rate in IVF treatment using ICSI.
