Situation non acceptable
Echecs récidivants de FIV avec ou sans anticorps anti-phospholipides
Dans cette situation, il faut d’abord rechercher la cause des avortements. Les IgIV n’ont pas fait la
preuve certaine de leur efficacité. Les études sont contradictoires.

Clark DA, Coulam CB, Stricker RB. Is intravenous immunoglobulins (IVIG) efficacious in early pregnancy failure?
A critical review and meta-analysis for patients who fail in vitro fertilization and embryo transfer (IVF). J Assist
Reprod Genet. 2006 Jan;23(1):1-13.
PROBLEM: Intravenous Immunoglobulins (IVIG) are widely used off label in the treatment of early reproductive
failure. As IVIG is expensive, and may have side-effects, evidence of efficacy is needed. Previous results have
suggested that the pre-conception treatment of primary recurrent abortion patients might be effective, but the data
set has been too small for adequate statistical power. More recently it has been suggested that IVIG may improve
the success rate of in vitro fertilization and embryo transfer (IVF) in patients with prior IVF failures, but clinical
trials have given conflicting results that need explanation. Systematic reviews generating inconclusive results
have focused on methodological rigor to the exclusion of biological plausibility. METHODS: Review of current
basic science of design, measurement, and evaluation of clinical trials and basic science mechanisms providing a
rationale for treatment. Meta-analysis of published randomized controlled and cohort-controlled trials (updated
with two unpublished data sets) evaluating IVIG treatment in IVF failure patients. Live birth rate was used as the
most relevant endpoint. The ability of different sources of IVIG to suppress natural killer (NK) cell activity was
determined using a standard (51)Cr-release assay in vitro. RESULTS AND CONCLUSIONS: Meta-analysis of
three published randomized controlled trials (RCTs) of IVIG in IVF failure patients shows a significant increase in
the live birth rate per woman (p = 0.012; Number Needed to Treat for 1 additional live birth, NNT = 6.0 women).
Using live birth rate per embryo transferred, and adding data from two cohort-controlled trials to the meta-analysis
further supports this conclusion (overall p = 0.000015, NNT = 3.7 women). Relevant variables appear to include
properties and scheduling of the IVIG, and selection of patients with abnormal immune test results. Different IVIG
preparations vary significantly in their ability to suppress NK activity in vitro. A rationale for use of IVIG is provided
by a review of mechanisms of IVIG action and mechanisms underlying failure of chromosomally normal embryos.

leukocyte antigen similarity by intravenous immunoglobulin. Reprod Biomed Online. 2005 Dec;11(6):745-9.
This study sought to assess the efficacy of intravenous immunoglobulin (IVIg) in improving pregnancy rates and
outcome, in a select group of patients with repeated IVF failure and human leukocyte antigen (HLA) similarity.
Couples suffering from recurrent IVF failure, defined as at least seven attempts at embryo transfer with no
successful implantations, who were found to share at least three HLA loci, and a negative cross-match test, were
included in the study. The treatment consisted of two 30 g IVIg doses: one before oocyte retrieval, and a second
as soon as a fetal pulse was identified on ultrasound. Ten couples comprised the study group. In total, these
couples had undergone 98 IVF cycles with no successful pregnancies prior to initiation of the study. Following a
total of 18 IVIg courses, seven women conceived, two women twice. Up to date, five women have delivered at
least one live fetus, at 27 weeks or later. One woman is currently in the early third trimester of a twin pregnancy,
and one woman had a late abortion at 19 weeks. The results suggest that couples with recurrent IVF failure and
HLA similarity, may benefit from IVIg treatment.

.
Intravenous (IV) immunoglobulin (Ig) has been previously shown to increase pregnancy rates after previously
failed in vitro fertilization (IVF) embryo (ET) attempts in women who are efficient embryo producers (fertilize at
least 50% of oocytes retrieved and generate at least 3 embryos/cycle). Women experiencing implantation failure
have a higher frequency of elevated percentage of circulating CD56+ (natural killer) cells (>12%) than fertile
women (3-12%). To evaluate the effects of IVIg on pregnancy rates in women with elevated percentage of
circulating CD56+ cells, 32 women who had previously failed IVF/ET (>12 embryos transferred without
pregnancy) were studied. Pregnancy and live birth rates with and without IVIg were compared in the same
woman. All 32 women had previously failed to conceive after at least 12 ET, were efficient embryo producers and
had persistently elevated plasma concentrations of CD56+ cells. Each woman received IVIg 500mg/kg prior to
ET. If serum hCG concentrations were positive for pregnancy, IVIg was continued at 500mg/kg/mo until 28 weeks
gestation. Pregnancy rates with and without IVIg were 56% and 9% (P<0.0001). The rate of live birth was 38%

with IVIg and 0% without IVIg (P<0.0001). IVIg enhances pregnancy and live birth rates in women with elevated
circulating CD56+ cells who have a history of implantation failure. Despite technologic advances leading to
enhancement of fertilization rates after in vitro fertilization (IVF) (1, 2) implantation rates after embryo transfer (ET)
have not increased significantly (3) over the last 20 years (4). Implantation rates after IVF/ET are influenced by
the quality of the embryos and receptivity of the endometrium (3-9). Endometrial receptivity involves both
hormonal (10-13) and immunologic (14-29) factors. Among the immunologic factors that play a crucial role in
successful implantation are natural killer (NK) cells (14-18). NK cells present within the decidua that express
CD56(but lack CD 16) have been associated with successful implantation (14-18). A deficiency of decidual
CD56+ CD16- cells (18) and an increase in circulating CD56+ cells (25, 26) have been observed in women
experiencing implantation failure. Women experiencing implantation failure after IVF and multiple ET have been
successfully treated with intravenous (IV) immunoglobulin (Ig) (27). IVIg reduces activation of NK cells and NK
killing activity both in vitro (29) and in vivo (30-31). This reduction in activation of NK cells is essential for normal
implantation to occur (14). To further define the role of IVIg for treatment of implantation failure, pregnancy and
live birth rates were compared before and after IVIg treatment in women undergoing IVF/ET who had elevated
levels of circulating CD56+ cells.

The aim of this study was to determine the effectiveness of intravenous (i.v.) immunoglobulin (Ig) for treatment of
individuals experiencing failure after in-vitro fertilization (IVF) and embryo transfer. A total of 29 women with
unexplained infertility who failed to become pregnant after IVF/embryo transfer were divided into two groups
based on performance in previous IVF cycles: 16 women had fertilization of > or = 50% of oocytes retrieved
and/or produced > or = 3 embryos each cycle and 13 had fertilization of < 50% of oocytes retrieved and/or
produced < 3 embryos each cycle. Each woman had received at least 12 transferred embryos (95th percentile for
successful IVF patients) or had experienced two or more biochemical pregnancies without ultrasonic confirmation
of implantation during previous IVF/embryo transfer attempts. All women received i.v. Ig 500 mg/kg prior to the
next embryo transfer. Only one of the 13 (8%) women with suboptimal fertilization and embryo yield became
pregnant in the treatment cycle. Of 16 women who had previously had fertilization of at least 50% of oocytes
retrieved and produced at least three embryos, nine (56%) became pregnant in the treatment cycle. The
difference in pregnancy rates between the two groups is significant (P = 0.02). Intravenous Ig is useful in the
treatment of unexplained IVF failure in women who have oocyte fertilization rates > or = 50% and generate at
least three embryos per cycle.

vitro fertilization-embryo transfer for patients with repeated failure of embryo transfer. Fertil Steril. 1996
Mar;65(3):655-8.
OBJECTIVE: To determine the effectiveness of immunotherapy with high-dose IV immunoglobulin preceding IVFET for patients with repeated failure of ET. DESIGN: Prospective, observational. SETTING: Assisted
Reproduction Unit of the Hospital Clínic i Provincial in Barcelona, a tertiary care setting. PATIENTS: Twelve
consecutive tubal infertility patients experiencing repeated unexplained IVF-ET failure including at least three ETs
replacing three to four fresh embryos each. Two women shared three or more human leukocyte antigens (HLA)
with the husband. INTERVENTION: During the subsequent new IVF-ET cycle, each patient received 400 mg/kg
IV immunoglobulin daily for 5 days during ovarian stimulation, that is, 5 to 7 days before ET. MAIN OUTCOME
MEASURES: Clinical pregnancies. RESULTS: No implantation occurred. There were no side effects.
CONCLUSIONS: High-dose IV immunoglobulin is not a useful tool for IVF-ET failure.

immunoglobulin: a randomized, placebo-controlled Canadian trial..Fertil Steril. 2000 Dec;74(6):1108-13.
OBJECTIVE: To evaluate the effect of intravenous immunoglobulin (IVIG) on pregnancy outcome in couples with
repeated unexplained in vitro fertilization (IVF) failure. DESIGN: Prospective, randomized, double blind, placebocontrolled clinical trial. SETTING: A university-based and a free-standing IVF program. PATIENT(S): Fifty-one
couples with a history of repeated unexplained IVF failure who were preparing for another fresh IVF cycle or
replacement of cryopreserved embryos. INTERVENTION(S): Eligible women underwent a standard IVF
stimulation using a long luteal phase GnRH analog protocol. Cryopreserved embryos were replaced after
endometrial preparation with oral micronized estradiol and subsequent vaginal progesterone. The women were
randomly selected to receive IVIG (500 mg/kg) or an equivalent volume of normal saline. The first infusion was
given on the day of embryo transfer or during the preceding 72 hours. The second infusion was given 4 weeks

later if a clinical pregnancy was confirmed by ultrasound. MAIN OUTCOME MEASURE(S): Live-birth rates.
RESULT(S): Overall, the live-birth rates were 4/26 (15%) for the IVIG group and 3/25 (12%) for the placebo group
(P=0. 52). There were 39 fresh IVF cycles, which yielded a clinical pregnancy rate of 28%, with live-birth rates of
4/21 (19%) for the IVIG group and 3/18 (17%) for the placebo group (P=0.59). CONCLUSION(S): In this
randomized clinical trial, IVIG did not improve the live-birth rate in couples with repeated unexplained IVF failure,
stringently defined by known determinants of IVF outcome.
