Thank you!

Very respectfully, I do not believe it is in your interst to do another ER until the endometriomas have been completely removed. In my opinion, The ovay(ies) housing the endometrioma(s) are far less likely to propagate good quality eggs. After surgery you will need 6-8 weeks to allow them to reconstitute, before beginning another ER cycle.

Good luck!

____________________________________________________

When women with infertility due to endometriosis seek treatment, they are all too often advised to first try ovarian stimulation (ovulation Induction) with intrauterine insemination (IUI) ………as if to say that this would be just as likely to result in a baby as would in vitro fertilization (IVF). Nothing could be further from reality It is time to set the record straight. And hence this communication!

Bear in mind that the cost of treatment comprises both financial and emotional components and that it is the cost of having a baby rather than cost of a procedure. Then consider the fact that regardless of her age or the severity of the condition, women with infertility due to endometriosis are several fold more likely to have a baby per treatment cycle of IVF than with IUI. It follows that there is a distinct advantage in doing IVF first, rather than as a last resort.

So then, why is it that ovulation induction with or without IUI is routinely offered proposed preferentially to women with mild to moderately severe endometriosis? Could it in part be due to the fact that most practicing doctors do not provide IVF services but are indeed remunerated for ovarian stimulation and IUI services and are thus economically incentivized to offer IUI as a first line approach? Or is because of the often erroneous belief that the use of fertility drugs will in all cases induce the release (ovulation) of multiple eggs at a time and thereby increase the chance of a pregnancy. The truth however is that while normally ovulating women (the majority of women who have mild to moderately severe endometriosis) respond to ovarian stimulation with fertility drugs by forming multiple follicles, they rarely ovulate > 1 (or at most 2) egg at a time. This is because such women usually only develop a single dominant follicle which upon ovulating leaves the others intact. This is the reason why normally ovulating women who undergo ovulation induction usually will not experience improved pregnancy potential, nor will they have a marked increase in multiple pregnancies. Conversely, non-ovulating women (as well as those with dysfunctional ovulation) who undergo ovulation induction, almost always develop multiple large follicles that tend to ovulate in unison. This increases the potential to conceive along with an increased risk multiple pregnancies.

So let me take a stab at explaining why IVF is more successful than IUI or surgical correction in the treatment of endometriosis-related infertility:

1. The toxic pelvic factor: Endometriosis is a condition where the lining of the uterus (the endometrium) grows outside the uterus. While this process begins early in the reproductive life of a woman, with notable exceptions, it only becomes manifest in the 2ndhalf of her reproductive life. After some time, these deposits bleed and when the blood absorbs it leaves a visible pigment that can be identified upon surgical exposure of the pelvis. Such endometriotic deposits invariably produce and release toxins” into the pelvic secretions that coat the surface of the membrane (the peritoneum) that envelops all abdominal and pelvic organs, including the uterus, tubes and ovaries. These toxins are referred to as “the peritoneal factor”. Following ovulation, the egg(s) must pass from the ovary (ies), through these toxic secretions to reach the sperm lying in wait in the outer part the fallopian tube (s) tube(s) where, the sperm lie in waiting. In the process of going from the ovary(ies) to the Fallopian tube(s) these eggs become exposed to the “peritoneal toxins” which alter s the envelopment of the egg (i.e. zona pellucida) making it much less receptive to being fertilized by sperm. As a consequence, if they are chromosomally normal such eggs are rendered much less likely to be successfully fertilized. Since almost all women with endometriosis have this problem, it is not difficult to understand why they are far less likely to conceive following ovulation (whether natural or induced through ovulation induction). This “toxic peritoneal factor impacts on eggs that are ovulated whether spontaneously (as in natural cycles) or following the use of fertility drugs and serves to explain why the chance of pregnancy is so significantly reduced in normally ovulating women with endometriosis.
2. The Immunologic Factor: About one third of women who have endometriosis will also have an immunologic implantation dysfunction (IID) linked to activation of uterine natural killer cells (NKa).  This will require selective immunotherapy with Intralipid infusions, and/or heparinoids (e.g. Clexane/Lovenox) that is much more effectively implemented in combination with IVF.
3. Surgical treatment of mild to moderate endometriosis does not usually improve pregnancy potential:. The reason is that endometriosis can be considered to be a “work in progress”. New lesions are constantly developing. So it is that for every endometriotic seen there are usually many non-pigmented deposits that are in the process of evolving but are not yet visible to the naked eye and such evolving (non-visible) lesions can also release the same “toxins that compromise fertilization. Accordingly, even after surgical removal of all visible lesions the invisible ones continue to release “toxins” and retain the ability to compromise natural fertilization. It also explains why surgery to remove endometriotic deposits in women with mild to moderate endometriosis usually will fail to significantly improve pregnancy generating potential. In contrast, IVF, by removing eggs from the ovaries prior to ovulation, fertilizing these outside of the body and then transferring the resulting embryo(s) to the uterus, bypasses the toxic pelvic environment and is therefore is the treatment of choice in cases of endometriosis-related infertility.
4. Ovarian Endometriomas: Women, who have advanced endometriosis, often have endometriotic ovarian cysts, known as endometriomas. These cysts contain decomposed menstrual blood that looks like melted chocolate…hence the name “chocolate cysts”. These space occupying lesions can activate ovarian connective tissue (stroma or theca) resulting in an overproduction of male hormones (especially testosterone). An excess of ovarian testosterone can severely compromise follicle and egg development in the affected ovary. Thus there are two reasons for treating endometriomas. The first is to alleviate symptoms and the second is to optimize egg and embryo quality.

 I am not suggesting that all women with infertility-related endometriosis should automatically resort to IVF. Quite to the contrary…. In spite of having reduced fertility potential, many women with mild to moderate endometriosis can and do go on to conceive on their own (without treatment). It is just that the chance of this happening is so is much lower than normal.

IN SUMMARY: For young ovulating women (< 35 years of age ) with endometriosis, who have normal reproductive anatomy and have fertile male partners, expectant treatment is often preferable to IUI or IVF. However, for older women, women who (regardless of their age) have any additional factor (e.g. pelvic adhesions, ovarian endometriomas, male infertility, IID or diminished ovarian reserve-DOR) IVF should be the primary treatment of choice.

………………………………………………………………..

Perhaps you do have underlying endometriosis but taking the BCP for some time before conceiving probably had nothing to do with your original success. Perhaps we should talk about your secondary infertility.

It is one thing for a woman who has never been able to conceive (primary infertility) to come to grips with undergoing In Vitro Fertilization. It is quite another matter for someone who has successfully achieved a pregnancy in the past having to come to terms with a subsequent inability to conceive (secondary infertility). When this happens, it raises issues of guilt, a declining sense of self-worth and ultimately self-recrimination. The ramifications often impact family relationships involving partners and siblings. The truth is that secondary infertility can be just as difficult for individuals and family to deal with as primary infertility.

There are many factors that contribute to the problem of secondary infertility. These include:

Social and marital factors: In this modern day and age where at least one in two marriages ends in divorce, it is not surprising that there would be an inevitable hiatus in childbearing. This often results in a considerable delay in re-initiating family building. Since the biological clock keeps on ticking in the interim, advancing age can, and often does, have a profound affect on a woman’s ability to subsequently conceive and successfully complete a pregnancy. In my experience, this is one of the most common reasons for secondary infertility. In addition, by the time a decision is made to enter a new relationship, many men and women will have undergone a prior sterilization procedure which now needs to be addressed. To make matters worse, many such men and women first opt for surgical reversal of their occlusive surgery, only to learn in the end that the procedures were not successful, and they now need to consider in vitro fertilization (IVF) in one form or another.

Financial factors: Here, the cost of raising a child often weighs heavily, especially in this present tough economic climate. This is becoming more of an issue as women playing an ever increasing role as a primary bread winner.

Career demands: There can be little doubt that when it comes to climbing the career ladder, women are considerably disadvantaged by the fact that pregnancy and the immediate demands of child rearing take away from their ability to compete with men. As such, many women choose to delay having another child until such time as they have been able to make up for prior lost opportunity.

Medical barriers to fertility: Certain common medical conditions, while not absolutely precluding pregnancy, make it much more difficult to conceive.

Endometriosis: It is not uncommon for women with endometriosis to achieve a pregnancy, but find difficulty in doing so again at a later date. The reason for this is that while most women with endometriosis have patent fallopian tubes, the environment surrounding their tubes is compromised due to pelvic toxins that are produced by the endometriotic implants. These toxins compromise egg fertilization potential, making it more difficult for sperm in the fallopian tube to fertilize the egg upon its arrival there. As such, endometriosis is one of the commonest causes of secondary infertility.

Tubal damage due to prior pelvic inflammatory disease: In first world countries, the early and often indiscriminate use of antibiotics for the slightest symptom has led to the point where an acute attack of pelvic inflammatory disease is often masked. As such, less than 30% of American women with tubal damage have knowledge that their tubes are compromised and that they might have subsequent difficulty in conceiving. Since, in many such cases the tubal damage will not have totally blocked both tubes, some of the women so affected might experience a pregnancy but have difficulty in conceiving again later down the line.

Dysfunctional ovulation: Since ovulation as well as normal hormonal support of the early implanting embryo are both essential for a healthy pregnancy to occur, it follows that women with irregular or dysfunctional ovulation (e.g., polycystic ovarian syndrome – PCOS, persistent follicular luteal phase deficiencies or post birth control pill ovulatory problems) might sporadically conceive and thereupon find it difficult to do achieve another pregnancy later on.

Immunologic Implantation Dysfunction (IID): has become ever more apparent that immunologic factors play an important role in achieving healthy implantation. Women with endometriosis (regardless of its severity), those with a personal or family history of autoimmune diseases such as lupus erythematosus, rheumatoid arthritis and thyroid autoimmunity (TAI), and some cases where the man and the woman share certain genetic similarities (alloimmune implantation dysfunction), will have activated CTL/NK cells that  can inhibit or compromise healthy implantation. This is an often overlooked cause of secondary infertility. Most such autoimmune/alloimmune cases require selective immunotherapy and IVF.

Antisperm Antibodies: Although infrequent, some cases of secondary infertility might also be caused by the woman harboring antisperm antibodies. In such cases IVF is mandated.

Previous post-pregnancy uterine infection: Retention of products of conception after the birth of a child, miscarriage, or abortion can so damage the uterine lining as to result in subsequent implantation failure. Unless specifically looked for, this will usually be unknown to the patient, who will simply present with secondary infertility. Treatment is often difficult because such patients might not respond adequately to surgical removal of intrauterine scar tissue or to hormonal or Viagra therapy

Male immunologic factors: Most men who have undergone a previous vasectomy more than 10 years earlier, will have antisperm antibodies that will interfere with fertilization. Such cases require IVF with intracytoplasmic sperm injection (ICSI). Here we offer a few words of caution to men who are considering undergoing surgical reversal of vasectomy. Always first have a test done to exclude the presence of circulating antisperm antibodies, because in such cases, even if the reversal is successfully performed, they will not be able to initiate a pregnancy without IVF/ICSI.

Whatever the cause, secondary infertility often affects older couples disproportionately, creating a sense of urgency and even desperation in achieving a viable pregnancy before time runs out. It is for this reason that IVF becomes the treatment of choice in such cases. However, even IVF becomes progressively less successful with advancing age of the woman (whose eggs are being fertilized). In such cases it is important for the couple to be realistic with regard to their expectations. Here, options that include embryo banking and egg donation should be carefully considered.

Another important point is that whenever a regularly ovulating younger woman (under 36 years of age) with patent fallopian tubes is diagnosed with secondary infertility, it is essential to consider underlying endometriosis or non-obstructive tubal disease as a possible cause. In such cases, IVF is again the treatment of choice.

………………………………………………………………..

You are at the right place.

Currently, with few exceptions, practitioners of assisted reproduction tend to attribute “unexplained and/or repeated” IVF failure(s), almost exclusively to poor embryo quality, advocating adjusted protocols for ovarian stimulation and/or gamete and embryo preparation as a potential remedy. The idea, having failed IVF, that all it takes to ultimately succeed is to keep trying the same recipe is over-simplistic.

The implantation process begins six or seven days after fertilization of the egg. At this time, specialized embryonic cells (i.e., trophoblasts), that later become the placenta begin growing into the uterine lining. When the trophoblast and the uterine lining meet, they, along with immune cells in the lining, become involved in a “cross talk” through mutual exchange of hormone-like substances called cytokines. Because of this complex immunologic interplay, the uterus can foster the embryo’s successful growth. Thus, from the earliest stage, the trophoblast establishes the very foundation for the nutritional, hormonal and respiratory interchange between mother and baby.  In this manner, the interactive process of implantation is not only central to survival in early pregnancy but also to the quality of life after birth.

There is an ever growing realization, recognition, and acceptance of the fact that uterine immunologic dysfunction can lead to immunologic implantation dysfunction (IID) with “unexplained” infertility, IVF failure, and recurrent pregnancy loss (RPL).

DIAGNOSIS 

Because immunologic problems may lead to implantation failure, it is important to properly evaluate women with risk factors such as:

• Unexplained or recurrent IVF failures
• Unexplained infertility or a family history of autoimmune diseases (e.g., rheumatoid arthritis, lupus erythematosus and hypothyroidism).
• Recurrent Pregnancy Loss (RPL)
• Endometriosis
• A personal or family history of autoimmune conditions, e.g., Rheumatoid Arthritis, Lupus erythematosus, autoimmune hypothyroidism (Hashimoto’s disease) etc.

Considering its importance, it is not surprising that the failure of a properly functioning immunologic interaction during implantation has been implicated as a cause of recurrent miscarriage, late pregnancy fetal loss, IVF failure and infertility. A partial list of immunologic factors that may be involved in these situations includes:

• Antiphospholipid antibodies (APA)
• Antithyroid antibodies (ATA/AMA)
• Activated natural killer cells (NKa)

ACTIVATED NATURAL KILLER CELLS (NKa):

Following ovulation and during early pregnancy, NK cells and T-cells comprise more than 80% of the lymphocyte-immune cells that frequent the uterine lining. These lymphocytes (white blood cells) journey from the bone marrow to the uterus and under hormonal regulation, proliferate there. After exposure to progesterone (due to induced /spontaneous exogenous administration), they begin to produce TH-1 and TH-2 cytokines. TH-2 cytokines are humoral in nature and induce the trophoblast (“root system of the embryo”) to permeate the uterine lining while TH-I cytokines induce a process referred to as apoptosis (cell suicide) thereby confining placental development to the inner part of the uterus. Optimal placental development (placentation) mandates that there be a balance between TH1 and TH-2 cytokines. Most of the cytokine production originates from NK cells (rather than from cytotoxic T-cells/Lymphocytes (CTL)). Excessive production/release of TH-1 cytokines, is toxic to the trophoblast and to endometrial cells, leading to programmed death/suicide (apoptosis) and subsequently to IID.

Functional NK cells reach a maximal concentration in the endometrium by about t day 6-7 days after exposure to progesterone …. This timing corresponds with when the embryo implants into the uterine lining (endometrium).

It is important to bear in mind that measurement of the concentration of blood NK cells has little or no relevance when it comes to assessing NK cell activation (NKa). Rather, it is the NK cell activation that matters. In fact, there are certain conditions (such as with endometriosis) where the NK cell blood concentration is below normal, but NK cell activation is markedly increased.

There are several methods by which NK cell activation (cytotoxicity) can be assessed in the laboratory. Methods such as immunohistochemical assessment of uterine NK cells and/or through measurement of uterine or blood TH-1 cytokines. However, the K-562 target cell blood test still remains the gold standard. With this test, NK cells, isolated from the woman’s blood using Flow Cytometry are incubated in the presence of specific “target cells”. The percentage (%) of “target cells” killed is then quantified. More than 12% killing suggests a level of NK cell activation that usually requires treatment.

Currently, there are less than a half dozen Reproductive Immunology Reference Laboratories in the U.S.A that are capable of performing the K-562 target cell test reliably.

There exists a pervasive but blatant misconception on the part of many, that the addition of IL or IVIg to a concentration of NK cells could have an immediate down-regulatory effect on NK cell activity. Neither IVIg nor IL is capable of significantly suppressing already activated “functional NK cells”. They are believed to work through “regulating” NK cell progenitors which only thereupon will start to propagate down-regulated NK cells. Thus, testing for a therapeutic effect would require that the IL/IVIg infusion be done about 14 days prior to ovulation or progesterone administration…  in order to allow for a sufficient number of normal (non-activated) “functional” NK cell” to be present at the implantation site when the embryos are transferred.

Failure to recognize this reality has, in our opinion, established an erroneous demand by practicing IVF doctors, that Reproductive Immunology Reference Laboratories report on NK cell activity before and again, immediately following laboratory exposure to IVIg and/or IL in different concentrations. Allegedly, this is to allow the treating physician to report back to their patient(s) on whether an  IL or IVIG infusion will be effective in down-regulating their Nka.  But, since already activated NK cells (NKa) cannot be deactivated in the laboratory, effective NKa down-regulation can only be adequately accomplished through deactivation of NK cell “progenitors /parental” NK cells in order too allow them thereupon, to s propagate normal “functional” NK cells and his takes about 10-14 days, such practice  would be of little clinical benefit. This is because even if blood were to be drawn 10 -14 days after IL/IVIg treatment it would require at least  an additional 10 -14days to receive results from the laboratory, by which time it would be far too late to be of practical advantage.

ANTIPHOSPHOLIPID ANTIBODIES:

 Many women who experience “unexplained” IVF failure, women with RPL, those with a personal or family history of autoimmune diseases such as lupus erythematosus, rheumatoid arthritis, scleroderma, and dermatomyositis (etc.)  as well as women who have endometriosis (“silent” or overt) test positive for APAs. More than 30 years ago, we were the first to propose that women who test positive for APA’s be treated with a mini-dose heparin to improve IVF implantation and thus birth rates. This approach was based upon research that suggested that heparin repels APAs from the surface of the trophoblast (the embryo’s “root system) thereby reducing its ant-implantation effects.  We subsequently demonstrated that such therapy only improved IVF outcome in women whose APAs were directed against two specific IgG and/or IgM phospholipids [i.e., phosphatidylethanolamine (PE) and phosphatidylserine (PS)].  More recently low dosage heparin therapy has been supplanted using longer acting low molecular weight heparinoids such as Lovenox and Clexane.   It is very possible that APAs alone do not cause IID but that their presence might help to identify a population at risk due to concomitant activation of uterine natural killer cells (Nka) which through excessive TH-1 cytokine production causes in IID: This is supported by the following observations:

• The presence of female APAs in cases of male factor cases appears to bear no relationship to IID.
• Only APA positive women who also test positive for abnormal NK activity appear to benefit from selective immunotherapy with intralipid/IVIg/ steroids.
• Most APA positive women who have increased NK cell activity also harbor IgG or IgM phosphatidylethanolamine (PE) and phosphatidylserine (PS) antibodies.

ANTITHYROID ANTIBODIES: (ATA).

 A clear relationship has been established between ATA and reproductive failure (especially recurrent miscarriage and infertility).

Between 2% and 5% of women of the childbearing age have reduced thyroid hormone activity (hypothyroidism). Women with hypothyroidism often manifest with reproductive failure i.e., infertility, unexplained (often repeated) IVF failure, or recurrent pregnancy loss (RPL). The condition is 5-10 times more common in women than in men. In most cases hypothyroidism is caused by damage to the thyroid gland resulting from of thyroid autoimmunity (Hashimoto’s disease) caused by damage done to the thyroid gland by antithyroglobulin and antimicrosomal auto-antibodies. 

The increased prevalence of hypothyroidism and thyroid autoimmunity (TAI) in women is likely the result of a combination of genetic factors, estrogen-related effects, and chromosome X abnormalities.  This having been said, there is significantly increased incidence of thyroid antibodies in non-pregnant women with a history of infertility and recurrent pregnancy loss and thyroid antibodies ^can be present asymptomatically in women without them manifesting with overt clinical or endocrinologic evidence of thyroid disease. In addition, these antibodies may persist in women who have suffered from hyper- or hypothyroidism even after normalization of their thyroid function by appropriate pharmacological treatment. The manifestations of reproductive dysfunction thus seem to be linked more to the presence of thyroid autoimmunity (TAI) than to clinical existence of hypothyroidism and treatment of the latter does not routinely result in a subsequent improvement in reproductive performance.

It follows, that if antithyroid autoantibodies are associated with reproductive dysfunction they may serve as useful markers for predicting poor outcome in patients undergoing assisted reproductive technologies.

Some years back, I reported on the fact that 47% of women who harbor thyroid autoantibodies, regardless of the absence or presence of clinical hypothyroidism, have activated uterine natural killer cells (NKa) cells and cytotoxic lymphocytes (CTL) and that such women often present with reproductive dysfunction. We demonstrated that appropriate immunotherapy with IVIG or intralipid (IL) and steroids, subsequently often results in a significant improvement in reproductive performance in such cases.

The fact that almost 50% of women who harbor antithyroid antibodies do not have activated CTL/NK cells suggests that it is NOT the antithyroid antibodies themselves that cause reproductive dysfunction. The activation of CTL and NK cells that occurs in half of the cases with TAI is probably an epiphenomenon with the associated reproductive dysfunction being due to CTL/NK cell activation that damages the early “root system” (trophoblast) of the implanting embryo. We have shown that treatment of those women who have thyroid antibodies + NKa/CTL using IL/steroids, improves subsequent reproductive performance while women with thyroid antibodies who do not harbor NKa/CTL do not require or benefit from such treatment

TEATMENT OF IID:

The mainstay of treatment involves the selective use of :

• Intralipid (IL) infusion
• IVIg therapy
• Corticosteroids (Prednisone/dexamethasone)
• Heparinoids (Lovenox/Clexane)

Intralipid (IL) Therapy:  IL is a suspension of soybean lipid droplets in water and is primarily used as source of parenteral nutrition. When administered intravenously, IL provides essential fatty acids, linoleic acid (LA), an omega-6 fatty acid, and alpha-linolenic acid (ALA), an omega-3 fatty acid.     

It is thought that fatty acids within the emulsion serve as ligands that activate peroxisome proliferator-activated receptors (PPARs) expressed by the NK cells. This is believed to decrease NK cell cytotoxic activity, and thereby enhance implantation A growing number of IVF programs, including ours, perform egg retrieval under conscious sedation using Propofol, a short acting hypnotic agent.

            Whatever the exact mechanism of action might be, Intralipid acts primarily to suppress NK cell over-production of TH-I cytokines. It exerts a modulating effect on certain immune cellular mechanisms largely by down-regulating cytotoxic /activated natural killer cells (NKa). This effect is enhanced through the concomitant administration of corticosteroids such as dexamethasone, prednisolone and prednisone which augment immune modulation of T cells. The combined effect of IL + steroid therapy suppresses pro-inflammatory cellular TH1 cytokines such as interferon gamma and TNF-alpha that are produced in excess by activated NK cells and cytotoxic lymphocytes/T-cells (CTL).   IL will, in about 80% of cases, successfully down-regulate activated natural killer cells (NKa) over a period of 2-3 weeks. It is likely to be just as effective as IVIg in this respect but at a fraction of the cost and with a far lower incidence of side-effects. Its effect lasts for ~ 4-6 weeks when administered in early pregnancy.

            Can laboratory testing be used to assess for an immediate effect of IL on Nka suppression?  Since the downregulation of NKa through IL (or IVIg) therapy can take several weeks to become measurable, it follows that there is really no benefit in trying to assess the potential efficacy of such treatment by retesting NKa in the laboratory after adding IL (or IVIg) to the cells being tested.

IVIg Therapy:  Until about a decade ago, the only effective and available way (in the US) to down-regulate activated NK cells was through the intravenous administration of a blood product known as immunoglobulin-G (IVIg). The fear (albeit unfounded) that the administration of this product might lead to the transmission of viral infections such as HIV and hepatitis C, plus the high cost of IVIG along with the fact that significant side effects occurred about 20% of the time, led to bad press and bad publicity for the entire field of reproductive immunology. It was easier for RE’s to simply say “I don’t believe IVIg works” and thereby avoid risk and bad publicity. But the thousands of women who had babies because of NK cell activity being downregulated through its use, attests to IVIg’s efficacy. But those of us who felt morally obligated to many desperate patients who would not conceive without receiving IVIg were facing an uphill battle. The bad press caused by fear mongering took its toll and spawned a malicious controversy. It was only through the introduction of IL less (about 15-20 years ago ), that the tide began to turn in favor of those patients who required low cost, safe and effective immunotherapy to resolve their IID.

 Corticosteroid Therapy (e.g., Prednisone, and Dexamethasone): Corticosteroid therapy has become a mainstay in the treatment of most women undergoing IVF. It is believed by most to enhance implantation due to an overall immunomodulatory effect. Corticosteroids reduce TH-1 cytokine production by CTL. When given in combination with IL or IVIG they augment the implantation process. The prednisone or dexamethasone therapy must commence (along with IL/IVIg)  10-14 days prior to egg retrieval and continue until pregnancy is discounted or until the 10th week of pregnancy.

 Heparinoid Therapy: There is compelling evidence that the subcutaneous administration of low molecular heparin (Clexane, Lovenox) once daily, (starting with the onset of ovarian stimulation) can improve IVF birthrate in women who test positive for APAs and might prevent later pregnancy loss when used to treat certain thrombophilias (e.g. homozygous MTHFR mutation)

What About Baby Aspirin? In our opinion, aspirin has little (if any) value when it comes to IID, and besides, it could even reduce the chance of success. The reason for this is that aspirin thins the blood and increases the potential to bleed. This effect can last for up to a week and could complicate an egg retrieval procedure or result in “concealed” intrauterine bleeding at the time of embryo transfer, thereby potentially compromising IVF success.

TH-1 Cytokine Blockers (Enbrel, Humira): TH-1 cytokine blockers, (Enbrel and Humira) are in our opinion relatively ineffective in the IVF setting. There has to date been no convincing data to support their use. However, these blockers could have a role in the treatment of a threatened miscarriage thought to be due to CTL/NK activation, but not for IVF. The reason is that the very initial phase of implantation requires a cellular response involving TH-1 cytokines. To block them completely (rather than simply restore a TH-1:TH-2 balance as occurs with IL therapy) so very early on could compromise rather than benefit implantation.

Leukocyte Immunization Therapy (LIT): The subcutaneous injection of the male partner’s lymphocytes to the mother is thought to enhance the ability for the mother’s decidua (uterus) to recognize the DQ alpha matching embryo as “self” or “friend” and thereby avert its rejection. LIT has been shown to up-regulate Treg cells and thus down-regulate NK cell activation thereby improving decidual TH-1:TH-2 balance. Thus, there could be a therapeutic benefit from such therapy. However, the same benefit can be achieved through the use of IL plus corticosteroids. Besides, IL is much less expensive, and the use of LIT is prohibited by law in the U.S.A.

There are two categories of immunologic implantation dysfunction (IID) linked to NK cell activation (NKa).

Autoimmune Implantation Dysfunction: Here, the woman will often have a personal or family history of autoimmune conditions such as Rheumatoid arthritis, Lupus Erythematosus, and thyroid autoimmune activity (e.g., Hashimoto’s disease) etc. Autoimmune as well as in about one third of cases of endometriosis, regardless of severity.  Autoimmune sometimes also occurs in the absence of a personal or family history of autoimmune disease.

When it comes to treating  NKa in  IVF cases complicated by autoimmune implantation dysfunction,  the combination of daily oral dexamethasone commencing with the onset of ovarian stimulation and continuing until the 10th week of pregnancy, combined with an initial infusion of IL (100ml, 20% Il dissolved in 500cc of saline solution, 10-14  days prior to PGT-normal embryo transfer and repeated once more (only), as  soon as the blood pregnancy test is positive), the anticipated chance of a viable pregnancy occurring within 2 completed IVF attempts (including fresh + frozen ET’s)  in women under 39Y (who have normal ovarian reserve)  is approximately  65%.

Alloimmune Implantation Dysfunction: Here, NK cell activation results from uterine exposure to an embryo derived through fertilization by a spermatozoon that shares certain genotypic (HLA/DQ alpha) similarities  with that of the embryo recipient.

Partial DQ alpha/HLA match:  Couples who upon genotyping are shown to share only one DQ alpha/HLA gene are labeled as having a “partial match”. The detection of a “partial match” in association with NKa puts the couple at a considerable disadvantage with regard to IVF outcome. It should be emphasized however, that in the absence of associated Nka, DQ alpha/HLA matching whether “partial” or “total (see below) will NOT cause an IID. Since we presently have no way of determining which embryo carries a matching paternal DQ alpha gene, it follows that each embryo transferred will have about half the chance of propagating a viable pregnancy. Treatment of a partial DQ alpha/HLA match (+ Nka) involves the same IL, infusion as for autoimmune-Nka with one important caveat, namely that here we prescribe oral prednisone as adjunct therapy (rather than dexamethasone) and the IL infusion is repeated every 2-4 weeks following the diagnosis of pregnancy and continued until the 24th week of gestation. Additionally, (as alluded to elsewhere) in such cases we transfer a single (1) embryo at a time. This is because, the likelihood is that one out of two embryos will “match” and we are fearful that if we transfer >1 embryo, and one transferred embryos “matches” it could cause further activation of uterine NK cells and so prejudice the implantation of all transferred embryos. Here it should be emphasized that if associated with Nka, a matching embryo will still be at risk of rejection even in the presence of Intralipid (or IVIg) therapy.

Total (complete) DQ alpha Match:   Here the husband’s DQ alpha genotype matches both of that of his partner’s. While this occurs very infrequently, a total alloimmune (DQ alpha) match with accompanying Nka, means that the chance of a viable pregnancy resulting in a live birth at term, is unfortunately greatly diminished.  Several instances in our experience have required the use of a gestational surrogate.

It is indeed unfortunate that so many patients are being denied the ability to go from “infertility to family” simply because (for whatever reason) so many reproductive specialists refuse to embrace the role of immunologic factors in the genesis of intractable reproductive dysfunction. Hopefully this will change, and the sooner the better.
