ABSTRACT

PURPOSE: To study the effect of intramural fibroids on uterine and endometrial vascularity in infertile women scheduled for in-vitro fertilization (IVF). METHODS: 3D power Doppler was used to measure the endometrial volume and blood flow indices in 182 women with intramural fibroids not affecting the uterine cavity and compared them to a matched control group without fibroids. RESULTS: There was significantly increased vascularity in the endometrium of the fibroid group as denoted by higher endometrial VI (p = 0.018), FI (p = 0.027) and Endometrial VFI. No significant difference in mean uterine artery RI (p = 0.277) or PI (p = 0.187). Among the fibroid group 62.6% had a fibroid > 4 cm. Women with fibroids > 4 cm had a significantly higher Endometrial FI (p = 0.037), and VFI (p = 0.02). Uterine artery blood flow was not affected, as uterine RI (p = 0.369) and PI (p = 0.321) were not statistically different. Compared with the control group (non fibroid), women with fibroids > 4 cm had significantly higher endometrial VI (p = 0.013), FI (p = 0.004), and VFI (p < 0.001), whereas women with fibroid ≤ 4 cm had no statistically significant differences in VI (p = 0.292), FI (p = 0.198), and VFI (p = 0.304). CONCLUSION: Intramural fibroids > 4 cm significantly increase endometrial vascularity. This increase in blood flow may be a factor that affects the outcome of IVF.

ABSTRACT

OBJECTIVE: To assess whether endometrial injury in the cycle preceding controlled ovarian hyperstimulation during intracytoplasmic sperm injection (ICSI) improves the implantation and pregnancy rates. METHODS: Between January 1, 2016, and March 31, 2017, a randomized controlled trial was conducted at a center in Egypt among 300 women who met inclusion criteria (first ICSI cycle, aged <40 years, day-3 follicle-stimulating hormone <10 IU/L, normal serum prolactin, no uterine cavity abnormality). The women were randomly allocated using a web-based system to undergo endometrial scratch in the cycle preceding controlled ovarian hyperstimulation (n=150) or to a control group (n=150). Only data analysts were masked to group assignment. The primary outcomes were the implantation and clinical pregnancy rates at 14 days and 4 weeks after embryo transfer, respectively. Analyses were by intention to treat. RESULTS: The implantation rate was significantly higher in the endometrial scratch group (41.3% [90/218]) than in the control group (30.0% [63/210]; P<0.001). The clinical pregnancy rate was also significantly higher in the endometrial scratch group (44.2% [61/138]) than in the control group (30.4% [41/135]; P<0.001). CONCLUSION: Endometrial injury in the cycle preceding the stimulation cycle improved implantation and pregnancy rates during ICSI. CLINICALTRIALS.GOV: NCT02660125.

ABSTRACT

OBJECTIVE: To evaluate the impact of maternal body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) on labor progress in nulliparous women. METHODS: The present prospective cohort study enrolled primigravidae admitted to Kasr Al Ainy hospital, Cairo University, Egypt, during active labor between February 1, 2016, and February 28, 2017. Patients were classified into three equal groups using their BMI at admission: underweight (<18.5), normal weight (18.5-29.9), and obese (≥30). The primary outcome was the rate of cervical dilatation; secondary outcomes included the duration of the second stage of labor, neonatal delivery weight, and the mode of delivery. RESULTS: Among the 600 primigravidae enrolled (200 in each group), significant differences were recorded in the rates of cervical dilatation (P<0.001), and the duration of the active labor phase (P<0.001) and the whole of labor (P<0.001); in the obese group, the cervical dilatation rate was lowest and the durations of the active phase of labor and the whole of labor were longer. The incidence of intrapartum cesarean delivery (P<0.001) and neonatal delivery weight (P<0.001) also differed between the groups; both were highest in the obese group. CONCLUSIONS: Patterns in labor progress, including cervical dilatation rate and labor duration, differed among patients with different BMI. ClinicalTrials.gov: NCT02686073.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the role of maternal serum total Homocysteine (tHcy) and uterine artery (Ut-A) Doppler as predictors of preeclampsia (PE), intrauterine growth restriction (IUGR), and other complications related to poor placentation. PATIENTS AND METHODS: A prospective cohort study was conducted on 500 women with spontaneous pregnancies. tHcy was measured at 15-19 weeks, and then, Ut-A Doppler was performed at 18-22 weeks of pregnancy. RESULTS: 453 pregnant women completed the follow-up of the study. The tHcy and Ut-A resistance index were significantly higher in women who developed PE, IUGR, and other complications when compared to controls (tHcy: 7.033 ± 2.744, 6.321 ± 3.645, and 6.602 ± 2.469 vs 4.701 ± 2.082 µmol/L, respectively, p value <0.001 and Ut-A resistance index: 0.587 ± 0.072, 0.587 ± 0.053, and 0.597 ± 0.069 vs 0.524 ± 0.025, respectively, p value <0.001). The use of both tHcy assessment and Ut-A Doppler improved the sensitivity of prediction of PE relative to the use of each one alone (85.2 relative to 73.33 and 60%, respectively). CONCLUSION: The use of elevated homocysteine and uterine artery Doppler screening are valuable in prediction of preeclampsia, IUGR, and poor placentation disorders. CLINCALTRIAL.

ABSTRACT

BACKGROUND: Angiogenesis has been found to be among the most important factors in the pathogenesis of endometriosis. The formation of new blood vessels is critical for the survival of newly implanted endometriotic foci. The use of 3-D power Doppler allows for the demonstration of the dynamic vascular changes that occur during the process of in vitro fertilization (IVF). We aimed to evaluate the effect of ovarian endometrioma on uterine and ovarian blood flow in infertile women. MATERIALS AND METHODS: In a case-control study at a university teaching hospital, 138 women with unilateral ovarian endometrioma scheduled for IVF were compared to 138 women with male-factor or unexplained infertility. In the mid-luteal (peri-implantation) phase of the cycle, endometrial thickness, uterine and ovarian artery pulsatility index and resistance index, endometrial and ovarian volume, 3-D power Doppler vascularization index (VI), flow index (FI), and vascularization FI (VFI) values were measured in both groups. RESULTS: There were no significant differences (P>0.05) in endometrial thickness, uterine ovarian artery pulsatility index and resistance index, endometrial and ovarian volume, or VI, FI, and VFI between the two groups. Furthermore, the endometrial and ovarian Doppler indices were not influenced by endometrioma size. No significant differences were observed in the ovarian Doppler indices between endometrioma-containing ovaries and contralateral ovaries. CONCLUSION: Ovarian endometrioma is not associated with impaired endometrial and ovarian blood flows in infertile women scheduled for IVF, and it is not likely to affect endometrial receptivity or ovarian function through a vascular mechanism.
