PROBLEM: To compare the effect of heparin/aspirin therapy alone vs. heparin/aspirin in combination with intravenous immuno-globulin (IVIg) immunotherapy on in vitro fertilization (IVF) outcome of patients who test positive for antithyroid antibodies (ATAs). METHOD OF STUDY: Eighty-two women younger than 40 years of age whose infertility was related exclusively to female causes were evaluated. All tested positive for organ-specific antithyroid antibodies (antimicrosomal and/or antithyroglobulin antibodies), but negative for antiphospholipid antibodies. Thirty-seven of these women (group A) received H/A alone, whereas 45 (group B) received heparin/aspirin in combination with IVIg. RESULTS: Ten (27%) of women in group A and 23 (51%) of women in group B achieved live births after completion of a single IVF/embryo transfer cycle (P = 0.027). CONCLUSION: We conclude that IVIg therapy significantly improves IVF success rates in ATA+ women. 相似文献

PROBLEM: The effect of mini-dose heparin/aspirin (H/A) alone vs. combined intravenous immunoglobulin G (IVIg) and H/A on in vitro fertilization (IVF) birthrates in women who test seropositive for antiphospholipid antibodies (APA+) was evaluated, as was the question of whether outcome is influenced by the gammaglobulin isotype(s) or the phospholipid (PL) epitope(s) to which the APAs are directed. METHOD OF STUDY : A case-control study was conducted in three phases, spanning a 4-year period, in a multicenter clinical research environment. Six hundred eighty-seven APA+ women, who were younger than 40 years and who each, completed up to three consecutive IVF/embryo transfer cycles within a 12-month period, were given either H/A alone or H/A in combination with IVIg. Birthrates relative to the type of immunotherapy (i.e., H/A alone and H/A with IVIg) and APA profile were the main outcome measurements. RESULTS: In phase I, 687 women who tested APA+ to one or more PL epitopes underwent two or fewer IVF attempts for a total of 1050 IVF cycles. Four hundred seventy-seven (46%) births occurred in 923 IVF cycles in which H/A alone was administered. Twenty-two (17%) births occurred after 127 IVF cycles in which H/A was not administered. In phase II, 322 of 687 women tested positive for a single APA subtype. These subjects underwent up to two consecutive IVF attempts for a total of 521 IVF cycles while receiving H/A alone. The birthrate was significantly lower for women whose APAs were directed toward phosphatidylethanolamine (PE) or phosphatidylserine (PS) involving IgG or IgM isotypes than for women who had any other APA (17% vs. 43%). In phase III, 121 women who did not achieve live births after two consecutive IVF attempts in which H/A alone was administered received IVIg in combination with H/A during their third consecutive IVF cycle. The birth rate was 41% after these IVF cycles when anti-PS or anti-PE involving IgG or IgM isotypes were present, as compared with 17% when H/A alone was administered. The IVF outcome did not improve when IVIg was administered in association with any other single APA. CONCLUSIONS: The treatment of APA+ women with H/A alone improves IVF birthrates. This benefit is selective in that it does not apply in cases in which IgG- or IgM-related APAs are directed against PE or PS. In such cases, the addition of IVIg significantly improves the outcome. 相似文献

This study was undertaken to explore whether intervention withheparin and aspirin (H/A) in selected patients undergoing in-vitrofertilization (TVF) and embryo transfer could improve fecundityrates. Specifically, it explored the possibility that womendiagnosed with organic pelvic disease who demonstrated antiphospholipidantibodies (APA) could benefit from H/A administration in asimilar manner to that used in patients with recurrent pregnancyloss. We used an enzymelinked immunosorbent assay forsix different phospholipids to identify patients who expressedAPA before they underwent IVF/embryo transfer. This study wasconfined to the first IVF/embryo transfer cycle that followedassessment of APA status and accordingly, the number of IVF/embryotransfer cycles corresponds with the number of patients treated.APA seropositive patients were treated with aspirin, 81 mg orallyq.d., and heparin 5000 IU s.c. b.i.d., beginning on day 1 ofcontrolled ovarian stimulation. The endpoint for success wasa live birth or an ultrasound confirming fetal cardiac activity(a viable pregnancy). The prevalence of APA in patients diagnosedwith organic pelvic disease (53%) was much higher than in thosewithout female pathology (14%). The administration of H/A toAPA seropositive patients significantly (P < 0.05) improvedthe viable pregnancy rate (49%) compared to the untreated APAseropositive group (16%). The viable pregnancy rate for APAseropositive women treated with H/A was also significantly (P< 0.001) higher than for untreated APA seronegative patients(27%). We conclude that all women undergoing IVF/embryo transfershould be tested for APA prior to initiating ovarian stimulation,and those with APA seropositivity should be treated with H/A. 相似文献

Problem The purpose of this study was to investigate whether treatment with TNF‐α inhibitors and/or intravenous immunoglobulin (IVIG) increases in vitro fertilization (IVF) success rates among young (<38 years) women with infertility and T helper 1/T helper 2 cytokine elevation. Method of study Seventy‐five sub‐fertile women with Th1/Th2 cytokine elevation were divided into four groups: Group I: Forty‐one patients using both IVIG and Adalimumab (Humira®), Group II: Twenty‐three patients using IVIG, Group III: Six patients using Humira®, and Group IV: Five patients using no IVIG or Humira®. Results The implantation rate (number of gestational sacs per embryo transferred, with an average of two embryos transferred by cycle) was 59% (50/85), 47% (21/45), 31% (4/13) and 0% (0/9) for groups I, II, III and IV respectively. The clinical pregnancy rate (fetal heart activity per IVF cycle started) was 80% (33/41), 57% (13/23), 50% (3/6) and 0% (0/5) and the live birth rate was 73% (30/41), 52% (12/23), 50% (3/6) and 0% (0/5) respectively. There was a significant improvement in implantation, clinical pregnancy and live birth rates for group I versus group IV (P = 0.0007, 0.0009, and 0.003, respectively) and for group II versus group IV (P = 0.009, 0.04 and 0.05, respectively). Conclusion The use of a TNF‐α inhibitor and IVIG significantly improves IVF outcome in young infertile women with Th1/Th2 cytokine elevation. 相似文献

Citation Zhong Y‐P, Ying Y, Wu H‐T, Zhou C‐Q, Xu Y‐W, Wang Q, Li J, Sheng X‐T, Li J. Impact of anticardiolipin antibody on the outcome of in vitro fertilization and embryo transfer. Am J Reprod Immunol 2011; 66: 504–509 Problem To investigate the impact of anticardiolipin antibody (ACA) on the outcome of in vitro fertilization and embryo transfer (IVF‐ET). Methods A total of 76 infertile women positive for anticardiolipin antibody (ACA+ group) and 819 controls negative for anticardiolipin antibody (ACA? group) undergoing IVF‐ET in the First Affiliated Hospital, to Sun Yat‐Sen University, were retrospectively analyzed. Women were diagnosed as having pure tubal factor infertility. Results The proportion of patients with a history of spontaneous abortion in the ACA+ group was significantly higher than that in ACA? group (19.7% versus 8.9%). The IVF rate, pregnancy rate and implantation rate in the ACA+ group were markedly lower than those in the ACA? group (75.5% versus 78.9%, 31.3% versus 48.6% and 16.1% versus 28.1%, respectively). Furthermore, the incidence of pregnancy loss in the ACA+ group was higher than that in the ACA? group (32.0% versus 15.1%). Conclusion ACA‐positive patients had significantly decreased IVF rate, pregnancy rate and implantation rate and high risk of abortion. Therefore, ACA positivity predicts poor outcome of IVF‐ET, and pre‐treatment to lower ACA level may be clinically beneficial for patients receiving IVF‐ET. 相似文献

Intravenous immunoglobulin (IVIG) has been introduced empirically into IVF/ICSI programs with the hopes of improving in vitro fertilization (IVF) success. However, the effects of IVIG have been inconsistent. We investigated the effects of IVIG on hard outcomes, including implantation rate, clinical pregnancy rate, live birth rate, miscarriage rate, and live birth rate per embryo transferred. The PubMed, EMBASE, and CNKI databases were searched up to June of 2013 and 10 studies were included. Case‐controlled studies comparing IVIG with placebo in IVF/ICSI women and/or unexplained infertility were included. Using fixed and random effects models, the pooled risk ratios (RR) with 95% confidence intervals (CIs) were calculated. The use of IVIG was significantly associated with a higher implantation rate and RR was 2.708 (95%CI: 1.302–5.629) compared with the placebo. The clinical pregnancy rate and the live birth rate were significantly increased in patients randomized to IVIG; RR was 1.475 (95%CI: 1.191–1.825) for the clinical pregnancy rate and RR was 1.616 (95%CI: 1.243–2.101) for the live birth rate. Moreover, the miscarriage rate was significantly less in patients randomized to IVIG (0.352, 95%CI: 0.168–0.738), but the live birthrate per embryo transferred was not (2.893; 95%CI: 0.810–10.331) less. Our results strongly support that IVIG is a useful treatment option for women undergoing repeated IVF failure. 相似文献

BACKGROUND: We investigated whether hereditary thrombophilia is more prevalent in women with recurrent IVF-embryo transfer failures. METHODS: This case-control study was conducted in an academic tertiary care hospital and compared 45 women with a history of four or more failed IVF cycles (group A) with 44 apparently healthy women matched for age and ethnic origin (group B). All participants were tested for inherited thrombophilias: mutations of prothrombin, factor V Leiden and methylene tetrahydrofolate reductase (MTHFR), and protein C, protein S and antithrombin III deficiencies. RESULTS: Excluding homozygotic MTHFR, the incidence of thrombophilia in group A, was 26.7% compared with 9.1% in group B (P = 0.003; odds ratio 2.9; 95% confidence interval 1.02-8.4). The incidence of thrombophilia in women with unexplained infertility in group A was 42.9% (9/21), compared with 18.2% in group B (P < 0.002). CONCLUSIONS: These data suggest that inherited thrombophilia may play a role in the aetiology of repeated IVF failures, particularly in the subgroup with unexplained fertility. 相似文献

Citation Winger EE, Reed JL, Ashoush S, El‐Toukhy T, Ahuja S, Taranissi M. Elevated preconception CD56+16+ and/or Th1:Th2 levels predict benefit from IVIG therapy in subfertile women undergoing IVF. Am J Reprod Immunol 2011; 66: 394–403 Problem We sought to answer two questions: First, is there a group of patients who benefit from intravenous immunoglobulin (IVIG) in IVF? Second can this group of patients be identified by preconception blood testing? Method of study A total of 202 IVF cycles in subfertile women were divided into four groups. Group I: 62 cycles with preconception Th1:Th2 ratio and/or % CD56+ cell elevation using IVIG; Group II: 27 cycles with similar Th1:Th2 and/or % CD56+ cell elevation not using IVIG; Group III: 71 cycles with normal Th1:Th2 and/or % CD56+ cell levels using IVIG; Group IV: 42 cycles with normal Th1:Th2 and % CD56+ levels not using IVIG. These groups were similar with regard to patient age, diagnosis, and past failure history. Results The implantation rate (number of gestational sacs per embryo transferred, with an average of two embryos transferred per cycle) was 45% (55/123), 22% (12/54), 54% (75/139), and 48% (40/84) for Groups I–IV, respectively. The clinical pregnancy rate (fetal heart activity per IVF cycle started) was 61% (38/62), 26% (7/27), 69% (49/71), and 71% (30/42), respectively. The live birth rate was 58% (36/62), 22% (6/27), 61% (43/71), and 71% (30/42), respectively, and the live birth per embryo transferred was 40% (49/123), 13% (7/24), 43% (60/139), and 48% (40/84), respectively. There was a significant improvement in implantation, clinical pregnancy, live birth rate and live birth rate per embryo transferred for Group I versus Group II (P = 0.0032, 0.0021, 0.0017, and 0.0002, respectively) and for Group II versus Group IV (P = 0.0021, 0.0002, <0.0001 and <0.0001, respectively). There was no significant difference in success rates between Groups I and III (P = 0.085, 0.23, 0.45, 0.34, respectively) and between Groups III and IV (P = 0.22, 0.48, 0.17, 0.31, respectively). Conclusion In subfertile women with preconception Th1:Th2 and/or % CD56+ cell elevation, IVF success rates are low without IVIG therapy but significantly improve with IVIG therapy. In patients with normal Th1:Th2 and normal CD56+ cell levels, IVF success rates were not further improved with IVIG therapy. IVIG may be a useful treatment option for patients with previous IVF failure and preconception Th1:Th2 and/or NK elevation. Preconception immune testing may be a critical tool for determining which patients will benefit from IVIG therapy. Prospective controlled studies (preferably double‐blind, stratified, and randomized) are needed for confirmation. 相似文献

Citation Winger EE, Reed JL, Ashoush S, El‐Toukhy T, Ahuja S, Taranissi M. Birth defect rates in women using Adalimumab (Humira®) to treat immunologic‐based infertility in IVF patients. Am J Reprod Immunol 2011; 66: 237–241 Problem This study compares the birth defect rate in women using preconception TNF‐α inhibitor (Adalimumab) during an in vitro fertilization (IVF) cycle to a similar population of women not using these immunologic therapies. Method of study One hundred subfertile women aged ≤38 years experienced ongoing pregnancies of which 36 resulted in twin pregnancies (136 babies). These successful cycles were divided into two different treatment groups: group I comprised 31 cycles (23 ICSI) using preconception Adalimumab (Humira) with or without pre‐ or post‐conception intravenous immunoglobulin (IVIG) (last dose of Humira given 65.3 ± 41.5 days before embryo transfer). Group II comprised 69 cycles (58 ICSI) with no exposure to Humira or IVIG. Group I included all eligible fresh cycles containing at least five 5‐celled embryos on day 3. Group II had similar entry criteria, but eligible cycles were randomly selected owing to a larger population size. Patients were later contacted by the clinic for neonatal health information. Results Delivery outcomes were as follows: group I experienced one case of DiGeorge syndrome (chromosome 22 deletion) that was electively terminated out of 41 babies (10 sets of twins) delivered. Group II experienced one case of neonatal heart defect and another case of Edward’s syndrome (Trisomy 18) out of 95 babies (26 sets of twins) delivered. The anomaly rate was 2.44% (1/41) and 2.11% (2/95) for groups I and II, respectively, comparable to the expected birth defect rate for the normal IVF population. Conclusion Preconception TNF‐α inhibitor does not appear to increase the birth defect rate in women undergoing IVF. A larger, clinical trial with blinded delivery assessment is needed to confirm these safety conclusions. 相似文献

Antiphospholipid antibodies (APA) have been identified in patients with recurrent pregnancy loss and IVF failure. Of these, antiphosphatidylethanolamine (aPE) and antiphosphatidylserine (aPS) may have special significance. A link between increased natural killer cell activity (NKa+) and trophoblast cell apoptosis has also been reported. This study was undertaken to determine how the APA profile was associated with peripheral NK cell activity. We evaluated 197 female IVF candidates for APA and NKa. Eighty-nine patients (45%) were APA+ and of these, 51 (57%) were aPE/aPS+. Fifty-four patients (27%) had increased NK cell activity. Some 51% of APA+ and 78% of aPE/aPS+ patients had increased NK cell activity compared with 8% and 13% when APA and aPE/aPS tested negative respectively (P: < 0.0001). Non-male factor infertility patients were APA+ and NKa+ in 57% and 34% of cases respectively, compared with 19% and 13% if a pure male factor was present. Some 88% of aPE/aPS+, non-male factor patients had increased NK cell activity, compared with 12% who tested aPE/aPS negative (P: < 0.0001) and 25% of aPE/aPS+, isolated male factor patients (P: < 0.0001). These findings establish a direct relationship between APA (specifically aPE/aPS) and increased peripheral NK cell activity among non-male factor infertility patients. It is possible that APA do not directly cause reproductive failure but rather function as markers or intermediaries for an underlying, abnormal activation of cellular immunity. 相似文献

This study was conducted to compare early serum human chorionic gonadotrophin (HCG) concentrations in singleton pregnancies achieved after intracytoplasmic sperm injection (ICSI), with those achieved after conventional in-vitro fertilization (IVF). Early serum HCG, 14-16 days after embryo transfer, was analysed in 99 IVF pregnancies achieved after ICSI (group A), and compared to 105 conventional IVF pregnancies (group B). All women were treated at the IVF Unit, Lis Maternity Hospital. Records were studied retrospectively. The mean +/- SE serum HCG concentration on day 14 after embryo transfer in group A was 190.5 +/- 17.4 mIU/ml, compared to 195.7 +/- 14.03 mIU/ml in group B. HCG concentration 14 days after embryo transfer in both groups A and B was higher in women with mechanical factor than in couples with male factor infertility or unexplained infertility (246 +/- 31.4, 183.3 +/- 16.4, 177.98 +/- 14.3 mIU/ml respectively). On the 16th day after embryo transfer, the HCG concentration increased, and the difference between the groups was maintained. Only in the subgroup of unexplained infertility did we find a difference in concentrations of HCG between ICSI and conventional IVF: on the 16th day following embryo transfer in this group there was a significant difference in HCG concentrations (395. 8 +/- 21 and 545.6 +/- 45.7 respectively; P = 0.04). HCG concentrations did not differ overall in the conventional IVF pregnancies compared with those achieved by ICSI. However, a statistical difference in early serum HCG concentrations was found in relation to the aetiology of infertility. 相似文献

Simple enumerations of peripheral blood natural killer (CD56+ NK) cells, B cells and T cells have no predictive value in IVF treatment outcome 总被引:3,自引:0,他引:3

BACKGROUND: To evaluate the association between the absolute counts of the peripheral natural killer (NK) cells (including total CD56(+) NK cells, CD56(dim) NK cells and CD56(bright) NK cells), B cells and T cells on the implantation rate and miscarriage rate after IVF treatment. METHODS: This was a prospective observation study. A total of 138 patients who underwent IVF treatment from December 2002 to July 2003 were recruited to the study. Blood samples were obtained on the day of vaginal oocyte retrieval prior to the procedure. The absolute counts of lymphocytes, NK cells, B cells and T cells were identified by flow cytometry. These absolute counts and their relationships to IVF treatment outcome and miscarriage rate were analysed. RESULTS: There were no significant differences with regard the mean values of absolute lymphocyte count, T cell count, B cell count and NK cell count (including total CD56(+) NK, CD56(dim) NK and CD56(bright) NK cells) between the pregnant and non-pregnant groups and also between the ongoing pregnancy and miscarriage groups. The cause of infertility, duration of infertility, basal FSH levels, number of previous failed IVF treatments, number of previous miscarriages and stimulation characteristics were not significantly different between the pregnant and non-pregnant groups. Previous studies have suggested that women with a history of recurrent miscarriage and those with infertility accompanied by recurrent failed IVF treatments are associated with a peripheral blood NK cell percentage >12%, therefore further analysis of peripheral CD56(+) NK cell levels <12% (group A) and >12% (group B) was performed. There was no significant difference in implantation rate (group A: 17.0%; group B: 23.2%), pregnancy rate (group A: 36.6%; group B: 47.7%) or miscarriage rate (group A: 23.3%; group B: 28.6%). CONCLUSION: There were no significant differences between simple enumerations of peripheral blood NK cells (including total CD56(+) NK, CD56(dim) NK and CD56(bright) NK cells), B cells and T cells with IVF treatment outcome and pregnancy outcome. Women who had a peripheral NK cell level >12% did not have higher number of previous pregnancy losses. Importantly their pregnancy rate was not reduced and their miscarriages were not increased compared to women who had a peripheral NK cells level <12%. 相似文献

BACKGROUND: We aimed to study T-helper 1 (Th1) and Th2 intracellular cytokine expression in peripheral blood lymphocytes of women with recurrent spontaneous abortions (RSA) or infertility with multiple implantation failures after IVF cycles. METHODS: Twenty-six women with three or more RSA and 23 with two or more IVF failures (14 with no history of spontaneous abortion (SAB) and nine with more than one SAB) comprised the two study groups. Twenty-one non-pregnant healthy multiparous women served as controls. Proportions (%) of lymphocytes containing IFN-gamma, TNF-alpha, IL-4 and IL-10 and the Th1/Th2 ratios of IFN-gamma/IL-4, IFN-gamma/IL-10, TNF-alpha/IL-4 and TNF-alpha/IL-10 in CD3+, CD3+/CD8- (T helper) and CD3+/CD8+ (T suppressor) cells were measured by 4-colour flow cytometry. RESULTS: RSA women demonstrated significantly higher Th1/Th2 ratios of IFN-gamma/IL-4 (P < 0.01), TNF-alpha/IL-4 and TNF-alpha/IL-10 (P < 0.05 each) in CD3+/CD8- T helper cells than those of controls. The proportion of TNF-alpha producing CD3+/CD8- cells (P < 0.05), and the Th1/Th2 ratios of TNF-alpha/IL-4 (P < 0.05) and TNF-alpha/IL-10 (P < 0.005) in CD3+/CD8- cells were significantly higher in women with multiple IVF failures without SAB as compared with those of controls. CONCLUSIONS: The prevalence of dominant Th1 immune responses in peripheral blood lymphocytes may reflect the systemic contribution of Th1 cytokines to RSA or multiple implantation failures in IVF cycles. 相似文献

Of 682 women who had undergone in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) with embryo transfer, 84 were successful on two occasions, with 16 of these resulting in miscarriage before 20 completed weeks. Antiphospholipid antibodies (APA) were estimated by enzyme-linked immunosorbent assay in these women (group 1) and compared to two control groups: 42 fertile women with three or more miscarriages (group 2) and 60 women with primary infertility undergoing IVF or ICSI (group 3). An apparently higher prevalence of seropositivity was seen in group 1 women (25%) compared to the group 3 women (6.6%) and it was similar to that seen in group 2 women (21.4%). Therefore the recommendation that women with two consecutive miscarriages after IVF or ICSI should have APA estimations performed routinely may be justified. 相似文献

Effect of antiphospholipid antibodies in women undergoing in-vitro fertilization: role of heparin and aspirin 总被引:3,自引:4,他引:3

To describe the prevalence of antiphospholipid antibodies in women
undergoing in-vitro fertilization (IVF) and to determine if heparin and
aspirin affect implantation rates, 191 women with a history of infertility
undergoing IVF were prospectively tested for antiphospholipid antibodies.
This was a two-centre, non-randomized comparison of women with positive
antiphospholipid antibodies receiving heparin and aspirin versus standard
treatment. An enzyme-linked immunosorbent assay, with referenced standards
and known positive and negative sera on each plate, was utilized to measure
antibodies to cardiolipin, phosphatidylinositol, phosphatidylglycerol,
phosphatidylserine and phosphatidylethanolamine. Statistical analyses of
results included analysis of variance and Fisher's two-tailed exact test.
Antiphospholipid antibodies were detected in 18.8% of patients undergoing
IVF compared with only 5.5% in the 200 normal controls, 26% in 200 women
with recurrent pregnancy loss, and 32% in 200 women with systemic lupus
erythematosus. In conclusion, antiphospholipid antibodies were found more
frequently in women undergoing IVF than in the normal control population.
Although implantation rates appeared higher in the group of women treated
with heparin and aspirin, no statistically significant differences were
detected in implantation, pregnancy and ongoing pregnancy rates between
those who received standard therapy and those treated with heparin and
aspirin.

Problem: To analyse percentage of total and memory CD27+ B‐cells and other lymphocyte subpopulations in the peripheral blood (PB) and follicular fluid (FF) of infertile married couples. Method of study: Forty‐eight couples from in vitro fertilization/embryo transfer (IVF/ET) programme were divided into four groups: patients with previous unsuccessful fertilization (n = 13), ectopic pregnancy (n = 8), multiple (at least three) failed IVF/ET (n = 18) and missed abortions (n = 9). Control group consisted of 15 married couples with healthy children. Results: PB memory CD27+ B‐cells were significantly decreased in all groups of infertile patients compared with controls. First group had increased memory B‐cells percentages compared with the second group. The differences in the percentages of PB memory B‐cells in third and fourth group compared with the first group were not statistically significant. FF memory B‐cells in the first and third group were significantly increased compared with second and fourth group. The percentage of total FF B‐cells in all groups were significantly decreased compared with their percentage in PB. Male partners of women from the first group had had significantly increased percentages of memory B‐cells compared with the partners of women from the second group. Percentage of total T‐ and B‐cells, CD4+ and CD8+ T‐cells, NK cells and activated HLA‐DR+ T‐cells in all groups were not significantly different from controls. We found no statistically significant difference between immunoglobulin E levels in all groups of patients. We found lower levels of IgA and IgM in FF compared with serum in all groups. Conclusion: Infertile patients have significantly decreased percentage of CD27+ B‐cells in the PB. Abnormalities in the memory B‐cell compartment may contribute to the pathogenesis of infertility. In the T‐cell compartment abnormalities were not detected. It appears that hormonal stimulation did not influence cellular immunity parameters. 相似文献

Reproductive life table analysis indicates that the majority of reproductive failures result from post fertilization failures, whether before or after implantation. It is important to have a set of tests to clarify the diagnosis of the reproductive failure so that appropriate therapy can be instituted. To determine the frequency of abnormal immunologic tests among women experiencing reproductive failure, 108 patients were evaluated for the presence of antiphospholipid antibodies (APA); lupus anticoagulant (LA); thyroid-thyroglobulin and microsomal antibodies (TGT); embryotoxic factor (ETA); and systemic CD56+/CD16- cells. The frequency of abnormal results obtained from testing for APA, LA, TGT, ETA, and CD56+/CD16- cells among 108 patients with diagnoses of recurrent pregnancy loss (RPL)(n=45), unexplained infertility (n=45) including IVF failure (n=10), endometriosis (n=10), premature ovarian failure (n=5), and polycystic ovaries (n=3) were compared with 15 normal controls. Seventy of one hundred eight (65%) women experiencing reproductive failure had at least one positive test, compared to 1 of 15 (7%) controls (P=0.0001). Presence of phospholipid antibodies was the most frequently abnormal result followed by elevated CD56+/CD16 cells. The prevalence of a particular abnormal test varied among the diagnoses. The most frequent abnormal test among women with RPL was an increased percentage of CD56+/CD16- cells (40%), followed by APAs (29%), TGT (9%), and ETA (7%). The most frequent abnormal result among women with unexplained infertility was the presence of APAs (42%), followed by CD56+/CD16- cells (16%), ETA (16%), and TGT (9%). APA, CD56+/CD16- cells, ETA, and TGT are useful tools to assist in the diagnosis of reproductive failure. 相似文献

PROBLEM: Antiphospholipid antibodies (APA) are thought to be involved in recurrent pregnancy loss. Therefore, we investigated the impact of APA on pregnancy outcome in women undergoing in vitro fertilization and embryo transfer (IVF-ET). METHOD OF STUDY: Blood samples taken from 54 Korean women referred for IVF were tested for the presence of APA, anticardiolipin antibody IgG and IgM and lupus anticoagulant. The standard gonadotropin-releasing hormone agonist long protocol was used for ovarian stimulation. RESULTS: Nine patients (16.7%) were positive and 45 (83.3%) were negative for APA. There were no significant differences between the two groups in clinical characteristics such as age, infertility duration, and response to controlled ovarian hyperstimulation. However, pregnancy outcome significantly differed between the two groups (p < 0.05). The APA positive group and APA negative group had abortion rates of 62.5% and 20.0%, respectively and delivery rates of 37.5% and 80.0%, respectively. CONCLUSION: The presence of APA in women undergoing IVF-ET was associated with a poor pregnancy outcome. 相似文献
