Tests21.1.1
Which tests do I really need?That’s a very difficult question and in the end you will have to make your own decision based on what your consultant says. Dr Gorgy will allow you to ‘opt out’ of any tests you don’t want.
• Any lady with fertility problems will need their day 1-3 FSH, LH, prolactin and estrodiol (and ideally AMH) run and also their progesterone (about seven days before your period is due/seven days after ovulation).
• Any male partner will obviously need a semen analysis (there is no point trying to conceive if your partner turns out to have no live sperm).
• Initial female fertility testing will usually include some anatomical tests e.g., HSG/lap&dye to check for tubal blockages, ultrasound scan to check for normal ovaries. If your tubes are blocked, there is almost no chance of conceiving naturally (or with IUI) but a good chance of conceiving with IVF. If the scan reveals swollen, distorted tubes (hydrosalpinx), your chances of conceiving naturally will be reduced as it is likely that your tubes may be too damaged to allow the egg to travel down to the uterus. A large hydrosalpinx is also associated with reduced chances for IVF success due to inflammatory chemicals and toxic 'wash' from the hydro. Some docs think that treating the hydro during your cycle with steroids and antibiotics may be enough, but others prefer to remove or clip the non-functioning tube. This is a difficult decision, as its not impossible (but possibly unlikely) for a swollen tube to unblock itself given time. Surgery to open tubes (recanulation) typically has a fairly low success rate.
If your ovarian scan reveals more than about 12 follicles per side, that will indicate PCO which could mean that you might benefit from metformin and possibly drugs to stimulate ovulation (like clomid). This is because egg production is a competitive process, so large numbers of follicles mean that it can take a very long time for one follicle to compete and dominate the others in order to successfully ovulate. If your ovarian scan reveals an antral (mini) follicle count of less than 2 per side, that could be a sign of diminished ovarian reserve and might mean that you need to either hurry to have IVF before ovarian failure is complete or might need (eventually) to start thinking about donor egg treatment if you don't manage to get pregnant naturally.
• A saline contrast ultrasound (SIS, aquascan) will identify any major uterine anomalies (e.g., large fibroids, septa, polyps etc - having enough space in your uterus that isn't impinged by scar tissue or fibroids is necessary to allow an embryo to implant successfully and to grow - these anomalies can often be resected (cut away) if needed and will improve your chances. Different docs disagree about how large a septum or fibroid or how numberous polyps need to be to cause a problem). A saline contrast ultrasound can sometimes give an indication of whether your tubes are open or not.
• A hysteroscopy & laproscopy will identify (and hopefully treat) any fibroids, septa, polyps, scarring, endometriosis, adhesions etc. A hysteroscopy (and particularly a laproscopy) is considered to be more major surgery than an aqua scan or HSG, so it is usually reserved for cases where there are risk factors for tubal blockage, scarring or endometriosis (e.g., abdominal pain, hystory of PID infection, chlamydia, abnormal uterine ultrasounds, visible hydrosalpinges on ultrasound).
• Most ladies will ask their GP for the level 1 tests (see level 1). The most critical tests are probably the thyroid hormones (TSH and FT4, antithyroid antibodies and a thrombophilia (clotting) panel including antiphospholipid antibodies. TSH levels outside the range of 0.4-2 together with low normal FT4 are associated with significantly lower chances of live birth e.g., with IVF.
• Male and female karyotyping tests are expensive and rarely available on the NHS unless a couple have had 3+ miscarriages. Karyotyping anomalies are rare so most couples who have them will find their results are completely normal. However, for affected couples, it may mean that their chance of having a healthy baby is very low - or that it can be improved a lot by having IVF with PGD
• All ladies seeking full immune treatment will have the NK cytotoxicity assay run - or possibly a CD69 test or a NK biopsy (see NK assay)
• Almost all immune docs will want to run the TH1:TH2 cytokine ratio test (see cytokines).
• Most immune docs would recommend the tests for inherited thrombophilias (e.g., MTHFR) - see thrombophilias.
• Dr Gorgy, Beer Centre and Dr Sher would usually recommend testing for DQa (unless using sperm donor – where the need for it is less obvious - see DQa).
• Dr Gorgy and Beer Centre would usually recommend testing for LAD (although it is more difficult when using sperm donor) - see LAD.
• Dr Gorgy is now recommending testing for infection in both partners - see Chlamydia, ureaplasma and mycoplasmas.
• Some doctors would recommend testing for sperm DNA fragmentation.
21.2
Thrombophilias – MTHFR, PAI-1, Factor V Leiden, APLAs21.2.1
What are they?These are conditions which cause the blood to be ‘sticky’ and therefore have more propensity to form clots. They can be genetic (inherited) e.g., MTHFR, PAI-1, Factor II Prothrombin and Factor V Leiden and also Protein C and Protein S deficiencies or they can be non-genetic (acquired) e.g., all the antiphospholipid antibodies e.g., anticardiolipins(collectively known as APLAs). Pregnancy also raises the risk of acquired thrombophilia.
Thrombophilias may cause difficulty in getting and staying pregnant due to microclots compromising the blood flow (nutrition and oxygen) to the uterine lining and to the placenta. This can result in a poor lining and/or slow failure of the pregnancy leading to miscarriage.
Thrombophilias may also be a significant health risk leading, for example to stroke.
21.2.2
How are they tested for?MTHFR, Factor II Prothrombin (202010), PAI-1 and Factor V Leiden are tested for using genetic tests (on blood). APLAs are tested for by measuring antibody levels in the blood. The general tendency to clot is tested by doing physical clotting tests like the APTT. As well as the genetic test for the mutation which tends to cause elevated PAI-1 levels, the actual PAI-1 levels in the blood can also be tested (elevated levels mean that the body has an impaired ability to breakdown clots). Tests for APLAs and general clotting are usually available on the NHS.
Because chromosomes are always paired (one from mum and one from Dad), you can have one copy of the genetic thrombophilia mutations or two. MTHFR, for example, can be homozygous (where the patient has two copies of the 'faulty' MTHFR gene) or heterozygous (only one copy). Having only one copy of the gene is usually less serious than having both copies.
MTHFR polymorphism (having the ‘faulty’ MTHFR gene) is very common. More than half the UK population have at least one copy of the MTHFR gene. Having a single copy (heterozygous) is considered to be less of a problem than having two copies (homozygous). There is a Yahoo Group for MTHFR ladies (see Resources, below). PAI-1 polymorphism is also very common - about 20% of the population are homozygous 4G/4G and about 30% are heterozygous 4G/5G (the rest of the population are negative i.e., 5G/5G. The PAI-1 mutations are more common in ladies with PCOS.
Example results:
MTHFR – gene mutation C677T negative/positive heterozygous/positive homozygous
Factor V Leiden: Factor V G1691A mutation negative/positive homozygous/positive heterozygous
Factor II Mutation- Prothrombin Factor II G20210A negative/positive homozygous/positive heterozygous
PAI-1 negative (5G/5G)/positive heterozygous 4G/5G/positive homozygous 4G/4G
Dr Gorgy charges £250 for the genetic tests for Factor V, Factor II and MTHFR (PAI-1 is available at an extra cost).
Care charge £118 for the test for Factor V, £118 for the test for Factor II, £136 for the test for MTHFR and £153 for the test for PAI-1 4G/5G.
Dr Economou in Athens charges 260Eu for screening of genetic thrombophilias (MTHFR, PAI-1, Factor II, Factor V) and acquired thromophilias including antiphospholipid antibodies (see my thread on serum clinic).
21.2.3
How are they treated?For fertility they are generally treated with blood thinners e.g., clexane (20-100mg) during fertility treatment and pregnancy - see above (or other low molecular weight heparins), and sometimes additionally with aspirin (started before fertility treatment and continued through pregnancy - in some cases, continued for life) - see above.
In addition to blood thinners during treatment, for MTHFR homozygous, folic acid (5mg), B6 (20-50mg) and B12 (0.05-1mg) are usually prescribed (for MTHFR heterozygous, most ladies take at least 800mcg of folic acid but not necessarily the whole 5mg dose indicated for homozygous MTHFR and not necessarily extra B6 and B12. B6 and B12 absorption can also be impaired with the MTHFR mutation which is why supplementation with B6 and B12 is often suggested as well as folic acid. Bear in mind that B12 deficiency is high among vegetarians and B6 and B12 deficiency are sometimes implicated in luteal phase deficit. MTHFR causes problems in absorbing/using folic acid, so sometimes even a 5mg dose may result in deficient blood levels. Methyl folate (e.g., solgar methylfolate or femibion containing methylfolate) may be much more absorbable but is more expensive and not available on the NHS in the UK.
For PAI-1, metformin (850mg twice daily started 3 months before fertility treatment), folic acid 5mg, vitamin B6 20-50mg and vitamin B12 0.05-1mg are often prescribed but weight loss can also be important for ladies who have elevated PAI-1 or the genetic mutation which tends to lead to it. Some docs do not believe that metformin treatment is justified unless a test reveals high fasting glucose or insulin resistance.
Where a significant clotting issue is identified, you would normally need to see your GP, and if necessary a haematologist to understand and treat any long term implications. Mild thrombophilias may not be life threatening but could still prevent a healthy pregnancy.
Once you have transferred to the care of an obstetrician during pregnancy, he should be responsible for managing your clotting risks later in pregnancy and immediately after baby is born.
21.2.4
Where can I get more information/support?There are several support groups for ladies who are trying to conceive with thrombophilias
e.g.,
http://health.groups.yahoo.com/group/FVL-PG/ for factor V leiden
http://health.groups.yahoo.com/group/MTHFRPG/ for MTHFR
The treatment protocols are described above (under clexane).
There are some helpful articles about PAI-1 on this blog by Dr Trofatter:
http://www.healthline.com/blogs/pregnancy_childbirth/labels/PAI-1.html21.3
Thyroid tests21.3.1
Do I need my thyroid activity testing?An over or under active thyroid can significantly reduce your chances of conception even if it is still within the ‘normal’ range for the NHS. For example, the NHS will currently not treat a TSH level of 4 mIU/mL (= 4 IU/L) as requiring any medication for hypothyroid (because of its cost/benefit analysis). However, studies have shown that anything over 2 mIU/ml (=2 IU/L), especially where anti-thyroid antibodies are present is associated with a lower chance of a live birth.
e.g.
http://www.ajog.org/article/S0002-9378(06)00365-6/abstracthttp://www.gghjournal.com/volume26/1/pdf/ab14.pdfhttp://www.thyroid.org/professionals/publications/clinthy/clinthy_v237.pdfSo in my opinion, infertility patients should ask their GP for a basic thyroid screen and if, for example the TSH comes back at over 2 mIU/ml (2 IU/L) or high levels of antithyroid antibodies are present, seek advice from an endocrinologist who has experience with infertility or an immune fertility doctor as you may need to be prescribed thyroxine to reduce your TSH to below 2 mIU/ml. In the study above, where IVF patients had a TSH level greater than 2.5 mIU/ml and did not have FT4 levels in the high normal range, they were prescribed 50mcg per day of levothryoxine from the first day of IVF stimulation which lead to greatly improved pregnancy and live birth rates (reduced miscarriage rates) compared to similar ladies who where untreated.
DURING PREGNANCY the American Thyroid Association recommends TSH is maintained to:
First Trimester, TSH 0.1 – 2.5 mIU/L
Second Trimester, TSH 0.2 – 3.0 mIU/L
Third Trimester, TSH 0.3 – 3.0 mIU/L
http://thyroidguidelines.net/pregnancy/resultsThe presence of antithyroid antibodies, even if TSH levels are normal, appears to be associated with a reduced chance of pregnancy/IVF success, but at least one study has shown much improved results if patients with antithyroid antibodies are prescribed thyroxine together with aspirin and corticosteroids. The doctors used this protocol: levothyroxine 50 mcg/d orally + 100 mg oral aspirin + 10 mg Prednisolone from the first day of IVF stimulation. The prednisolone was increased to 30 mg/d for 5 days starting the day of embryo transfer, and then dropped back down to 10 mg/d and continued until at least 10 weeks of pregnancy.
http://www.rbej.com/content/7/1/137This study showed a reduced miscarriage rate and a higher rate of embryo quality where ladies with subclinical hypothyroid were prescribed thyroxine
http://www.fertstert.org/article/S0015-0282(10)02928-6/abstractBoth pregnancy and IVF can affect your thyroid hormones and increase the body's need for thyroxine so ladies with thyroid issues need their thyroid levels monitoring regularly in pregnancy, and if you have recently been through an IVF cycle you may want to wait a few weeks afterwards before (re)testing your levels to get an accurate baseline measurement.
The NHS CKS knowledge summary on managing subclinical hypothyroidism (where free T4 is normal but TSH is elevated) in pregnancy or when trying to conceive tells GPs to "Aim for a TSH concentration in the low-normal range (0.4 mU/L to 2.0 mU/L) and an FT4 concentration in the upper reference range." Please note that the CKS system is supposed to be being replaced soon but I don't think this invalidates the information on the database for the time being.
http://cks.nice.org.uk/hypothyroidism#!scenariorecommendation:6However, the NHS guidelines (unhelpfully) do not go as far as the logical next step of telling GPs to make sure that all ladies who are pregnant or trying to conceive should have TSH in the 0.4-2 range (only that if their TSH starts off higher than 4.5, to get it down to the 0.4-2 range).
Thyroid-stimulating hormone (TSH) 0.9–4.0 mU/L (aim for between 0.9 and 2.0 mU/L) - some ladies will feel fine with TSH down to about 0.4 and it will not cause any fertility problems, but most ladies feel better if TSH is closer to 1.
Free thyroxine (FT4) 9.0–25 picomol/L (aim for high end of this range e.g., 19-25 - but bear in mind that some women can't achieve this without dropping their TSH too much - so also be guided by how your feel and where your TSH is)
Free triiodothyronine (FT3) 3.5–7.8 picomol/L (aim to be in range)
Total thyroxine (TT4) 60–160 nanomol/L (aim to be in range)
Total triiodothyronine (TT3) 1.2–2.6 nanomol/L (aim to be in range)
Thyroxine supplementation will raise FT4 (and T3) which causes TSH to fall. Your doctor will normally start you on a low dose e.g., 25-50mcg per day and gradually tweak it upwards, retesting your TSH and FT4 every 4 weeks until you are on target. Thyroxine has a fairly long half life, so if you are in between doses, its quite common for doctors to put you on alternate day dosing e.g., 50mcg one day and then 75mcg on alternate days to 'average out' the dose that you need.
Once you do get pregnant, its important to follow the guidance on monitoring thryoid in pregnancy (i.e., blood tests on bfp and then monthly) because you may need to drop your thyroxine slightly in early pg and then start to raise it.
If you are TTC with stimulated own egg IVF, it is probably more critical to try to get your TSH below 2 and your FT4 up to the high normal range because during stimulation, the high levels of estrogen can push down your FT4 and raise your TSH so if you start with levels above 2, you are more likely to end up with levels well above normal (e.g,. 5) by the time you get to embryo transfer. In one study, 44% of women with a TSH below 2.5 had a rise in TSH when doing an OE IVF cycle.
http://www.fertstert.org/article/S0015-0282(11)02907-4/abstract 21.3.2
What is thyroid peroxidase? What is thyroglobulin antibodyThyroid peroxidase is one of the common anti-thyroid antibodies (ATAs). The second most common ATA is (anti) thyroglobulin antibody. Having an elevated level means that you have antibodies in your blood that attack your thyroid gland meaning that it is likely that now, or sometime in the future, your thyroid will be damaged and not produce the right amount of thyroid hormones (e.g., Hashimotos thyroiditis). It is an autoimmune condition and it is associated with an increased risk of having elevated natural killer cells. Even for ladies whose thyroid hormones fall within the normal range, chances of a live birth with IVF are reduced if it is not treated with a combination of thyroxine, blood thinners (e.g., clexane, aspirin) and corticosteroids (e.g., prednisolone).
http://www.rbej.com/content/7/1/137However, some ladies who are diagnosed with ATAs decide to have level 2 immune testing so that they can access more aggressive treatments e.g., intralipids, IVIG, humira, on top of the basic treatment (thyroxine, blood thinners and corticosteroids).
21.3.3
What thyroid tests do I need?If you are concerned about thyroid activity for fertility you need to know
- your TSH level (you are wanting this to be around 1 (between 0.4 and 2) for optimum fertility
- your FT4 levels (you want this to be in the top third of the normal range for optimum fertility - but see comment above)
- antithyroid antibodies (e.g., thyroid peroxidase, thyroglobulin antibody)
If your results show any problem you would want to ask for T3 and iodine to be tested. Its normal to feel some side effects when you first start thyroxine e.g., jitteryness but this should settle and you start to feel ok. If you do not start to feel ok, and still feel hypothyroid (overtired etc) after about 4 weeks on thyroxine, despite your TSH and FT4 getting into the normal range, you may need to check T3 because some patients have a problem converting T4 into T3 and occasionally, T3 supplementation may be necessary.
Knowing your iodine level will help you determine whether iodine is causing your thyroid problems and whether you should be on iodine supplements/changing your diet. If your results show a problem with antithyroid antibodies, you probably want to also ask for selenium, so you can determine whether you need extra selenium. A dose of 200-400mcg of organic selenium is often suggested. Bear in mind that too much iodine can make hashimotos (autoimmune thyroid disease) worse, particularly if selenium is low - so you must not take iodine containing supplements without a doctors' permission and ensuring your selenium is ok first if you have hashimotos. Too much selenium is toxic and linked to increased risk of diabetes, so you should ideally get your levels checked especially if you intend on taking a high dose for a long period.
Bear in mind that estrogen binds to T4 so high levels of estrogen will reduce Free-T4. After an IVF cycle, pregnancy/miscarriage or being on estrogen containing medication, you might need to wait for at least 4 weeks to get an accurate T4 level. Also, remember that the thyroid system is supposed to be dynamic - your body uses TSH to lever up and down your Free-T4 levels in order to set the body's 'thermostat'. So it should respond to extra demands by changing your TSH and FT4. Its therefore normal for your thyroid results to keep changing. What you are looking for is to get them into a good place before your fertility treatment starts, to give you some headroom in case estrogen pushes up your TSH and down your FT4, then to make sure they stay adequate when you are pregnant to give baby the right supply of thyroid hormones, particularly in the early weeks of pregnancy before baby can make his own thyroid hormones.
Steroids like prednisolone sometimes suppress TSH, so your doc is supposed to pay more attention to your FT4 level and possibly ignore an artificially low TSH level if you are on pred.
21.3.4
What causes thyroid problems?- the main cause worldwide is iodine deficiency - a recent study on schoolgirls in the UK found mild deficiency in 51%, moderate deficiency in 16% and severe deficiency in 1% - so its safe to say that iodine deficiency is common in the UK - but excessive iodine can also cause/exacerbate thyroid disease (particularly if there is a selenium deficiency).
- another major cause is autoimmune disease of the thyroid gland caused by antithyroid antibodies (hashimoto's or grave's disease).
Soya protein, brussels sprouts, broccoli, rutabaga/swede, turnips, kohlrabi, radishes, cauliflower, African cassava, millet, cabbage and kale are called goitrogenic foods and can also exacerbate thyroid disease.
21.3.5
What are the symptoms of under or overactive thyroid?Bear in mind that underactive thyroid that is sufficient to be reduce the chance of getting/staying pregnant may be symptomless. Overactive thyroid that is severe enough to reduce your chances will normally have obvious symptoms. You can get a list of the symptoms here:
http://thyroid.about.com/cs/basics_starthere/a/symptoms.htm21.4
TNFa – see cytokine ratio above or 21.5
Timescales for immune treatment21.5.1
What sort of timescale is typical for immune testing and treatment?For a hypothetical patient who, after testing with Dr Gorgy finds she has virtually every issue that there is (almost no-one is that unlucky), your experience might go something like this:
1) Attend first consult, decide to get Chicago tests done, decide to test for Chlamydia and get swabs done for mycoplasma and ureaplasma and a semen culture test.
2) Go back to your GP and get any missing basic tests run there (if possible)
3) Wait for your period to send Chlamydia sample for testing
4) When all results are back, have follow up appointment
5) If Chlamydia and other infection tests are positive start on antibiotics (both partners)
6) Wait for your second period after finishing the antibiotics to retest and make sure the infections are gone
7) Have hysteroscopy and endometrial biopsy if you need that (a lot of ladies don’t) and follow up on any issues
8) Have two shots of LIT (if needed), four weeks apart and start on Humira (if needed), possibly in between the shots of LIT.
9) Wait 1-3 weeks before retesting LAD and/or cytokine ratio (if needed).
10) Wait up to one week for results to come back before following up and getting any prescriptions that you still need.
11) Start your fertility treatment cycle and start taking aspirin (you should already be on a prenatal vitamin plus any extra folic acid, B6 and B12 that you have been advised to take if you are MTHFR positive)
12) Start clexane and prednisolone (if prescribed) on day 5/6/7 of your stimulation
13) Have IVIG and/or intralipids (if prescribed) 7-14 days before your planned embryo transfer
14) Stop your clexane from trigger day until the day after egg collection.
15) Start your gestone after egg collection
16) Confirm your pregnancy with a beta HCG test about 14 days after egg collection (and follow up with a second test 48 hours later to confirm that your levels are rising sufficiently – see Two Week Wait, below)
17) Have another IVIG/ILs asap (if prescribed) and have a LAD retest if not already done.
18) If LAD is still poor, book another LIT asap
19) Have your first ultrasound scan at 6.5 weeks (4.5 weeks after egg collection) to confirm a heartbeat and a further IVIG/ILs asap
20) Wait 7-10 days after the drip before retesting NKa
21) Wait one week after the retest for the results to come back and have a follow up consult to decide what the plan should be for future drips.
22) Have next drip in about four weeks (if prescribed), then a retest after 7-10 days, then a follow up one week later and repeat, possibly up until 31 weeks – if your retests are problematic. If your consultant feels its necessary, possibly have scans every four weeks.
23) Have your NHS nuchal scan and tests at twelve weeks
24) Stop your gestone at 12-16 weeks and start tapering off the prednisolone at twelve weeks (or as directed by your consultant).
25) Have your NHS anomaly scan at 20 weeks and further scans as your NHS OB dictates.
26) Stop your clexane at 31 weeks if you are cleared to do so by your consultant and your NHS OB.
Obviously, actual treatment plans may vary considerably from this.
21.6
Tocolytics - atisoban, nifedipine, ritodrine - 'womb relaxants'These are a group of drugs that were developed to try to reduce pre-term birth by stopping the uterus from contracting. This class of drugs are now being used by several clinics prior to and after embryo transfer in ladies who have experienced cramping on previous embryo transfers or where hypercontractility (excessive contractions of the uterine muscle) has been observed by their doctor during previous gynaecological procedures. These drugs act to reduce spontaneous uterine contractions (cramps), and it is hoped that by doing this, they may make the uterine environment more favourable for implantation. Ladies who have experienced cramping during ET and for up to about 3 days after ET in previous failed IVF's might like to discuss the possibility of taking these drugs for their next ET.
21.7
Treating empirically21.7.1
What is treating empirically? Can I just take immune meds without testing?Treating emprically means taking medication by common usage rather than after testing and scientific proof.
Lots of clinics worldwide will consider empirical immune treatment for ladies who have had repeat IVF failures or repeat miscarriage.
Emprical treatment for this often takes the form of continuous low dose daily aspirin (for possible clotting issues and/or low dose daily clexane (e.g., 20 mg) either from the mid-follicular phase (day 5/6/7) or, sometimes from ovulation/egg collection, or even from positive pregnancy test and/or low doses of corticosteroids (e.g., 5-15 mg prednisolone or prednisone or 0.75-1.5mg dexamethasone) from the mid-follicular phase, or from ovulation/egg collection, or from positive pregnancy test, and/or additional progesterone e.g., 50mg gestone injections from ovulation/egg collection.
From the point of view of supplements, Vitamin D3 is the most obvious supplement (see Supplements) to take as Vitamin D3 deficiency is very common in UK/northern Europe and Vitamin D is a potent immunoregulator.
The advantage of empirical treatment compared to comprehensive immune testing and treatment is basically cost (and the difference in cost between empirical treatment and comprehensive testing and treatment can be very, very large), and for some ladies practical access to treatment. These drugs are very commonly used and many doctors are happy to consider prescribing them after several IVF failures/miscarriages. For avoidance of doubt, I am not suggesting that anyone should take any medication without medical advice from their doctor.
The disadvantages are:
1) the treatment may have no benefit - e.g., you may be given blood thinners when you have no clotting or NK issues and they may not help you get/stay pregnant.
2) the treatment will always carry some risks e.g., immune suppression from taking steroids, or small increased risk of cleft lip/palate for baby - and these risks may be unnecessary if you don't need the treatment
3) the treatment may be at too low a dose to be effective.
Nevertheless, this type of treatment does seem to help a lot of ladies get/stay pregnant after they have failed to without it and it may be worth discussing with your doctor, but it won't be appropriate for everyone e.g., steroids may be very risky for ladies who have immunosuppression problems and blood thinners could be dangerous for ladies with other medical conditions. Ladies with significant known autoimmune issues may be more likely than average to require more comprehensive immune treatment to get/stay pregnant, some ladies will not want to to take the time to try empirical treatment before having more comprehensive testing or will be uncomfortable with taking medication which is not tailored for them on the basis of issues identified by comprehensive tests. Personally, I think it would be inappropriate to consider these sorts of treatments unless you do have a history of miscarriage and/or multiple IVF failures or are diagnosed with issues through comprehensive testing because they do carry some risks to you and to the fetus and it would not be justifiable to take them unless you need to.
Before starting a cycle using empirical treatment, personally, I would:
1) ask for an FBC to screen for any obvious immunosuppression - that would suggest taking steroids may be risky for you
2) ask for blood test screening for diabetes and thyroid issues (including antithyroid antibodies) in case they need treatment first
3) ask for rheumatoid arthritis and lupus blood test screening to identify if you are at high risk of having diagnosable autoimmune issues
4) ask for blood clotting (thrombophilia) tests - because if these reveal issues you may need blood thinners for medical reasons or at a higher dose.
essentially, these are the so-called level 1 tests.
5) consider whether to have infection screening particularly for Chlamydia with the greek test (see Chlamydia above) because that may be the undiagnosed root cause of many immune issues, lining issues and IVF failures and the test and treatment (aggressive antibiotics) seem particularly cost effective compared to full immune testing and treatment
6) decide whether you would prefer to try this route first, even if it fails, or would prefer/are able to go straight to comprehensive testing and treatment bearing in mind the relative cost of comprehensive testing/treatment and the financial and emotional cost of another cycle.
7)get your doc to have a good look in your uterus for problems like adenomyosis, septa, polyps, fibroids, scarring, adhesions. An aquascan will pick up some of these, and a hysteroscopy may pick up the rest.
21.8
Trying again21.8.1
When should I try for another baby after my immune pregnancy?Autoimmune issues run in families and I strongly believe that breastfeeding gives baby's immune system the best chance of being normal in the future, so I would hope that most ladies would want to give their special baby the benefit of breast milk for as long as possible - at least for 6 months, preferably for longer. Some immune related conditions e.g., diabetes and asthma, appear to be an increased risk for babies exposed to the antigens in formula milk. Breastfeeding is not always easy, especially if baby has health problems, but babies can always have the benefit of your milk if you express with a good quality pump.
However, getting pregnant naturally or with fertility treatment whilst breastfeeding is less likely due to elevated prolactin levels even if your natural cycles return and the risk of miscarriage is higher whilst breastfeeding. If you do find you are pregnant whilst breastfeeding, you may need to take the decision to stop breastfeeding if you have a history of miscarriage etc. Fertility treatment is not normally permitted whilst breastfeeding because of the risks to the breastfeeding baby due to the medication, the reduced chance of success and increased risk of miscarriage. Most clinics will recommend waiting for at least 2 normal periods after you stop breastfeeding or 1 period and a normal prolactin level by blood test before you restart fertility treatment.
However, Dr Beer used to say that the immune system reset for around 1 year after a successful pregnancy, so you may want to try again within a year for an improved chance. For example, you could breastfeed exclusively for 6 months whilst building up a stock of frozen expressed milk to reduce the need to expose your baby to formula milk whilst weaning.
21.9
Two-week wait (between ovulation and pregnancy test)21.9.1
Any do’s and don’ts during the 2ww and pregnancy?• Don’t exercise too much – your ovaries may be swollen after IVF and can twist causing damage if you try to do more than your body is very used to.
• Do drink plenty of water and ensure sufficient protein intake to help prevent OHSS and reduce constipation.
• Try to avoid baths, swimming pools, Jacuzzis etc – they can cause overheating/dehydration which is unhelpful for your embryos and there is a small risk of infection – stick to a warm (not hot) shower.
• Do try and avoid anyone you know is ill with anything contagious like colds or flu– especially someone with chickenpox (unless you have checked that are immune with a blood test) – you may be slightly immunosuppressed due to steroids or Humira, and if not, you don’t want to catch anything that will then cause your NKa and TNFa to rise.
• Do try to eat sensibly – to provide protein, avoid saturated fats that may increase TNFa and to reduce the constipation that comes with taking progesterone.
• Do try to rest more than usual – ‘normal’ ladies do get pregnant without resting during their 2ww but ‘immune Tx’ ladies need all the help they can get to keep their immune system calm and quiet.
• Do avoid caffeine (coffee, tea, chocolate, cola, red bull, iron bru, energy drinks etc). Studies suggest four cups of coffee don’t raise the miscarriage risk in ‘normal’ ladies, but I think ladies with immune issues need all the help they can get, particularly as they may suffer from impaired blood flow to the uterine lining which caffeine will exacerbate. I wouldn’t drink more than two cups of (green) tea. (I would avoid decaff tea as the processing to get the caffeine out leaves traces of chemicals – decaff coffee is safer.) In addition, risk of blood clots rises significantly during pregnancy and drinks like red bull in particular have been shown to also raise clotting risk, so I think they are too dangerous to drink during pregnancy.
• Personally, I would avoid artificial sweeteners (especially aspartame, acesulfame-K, sodium cyclamate and saccharine) because some practitioners say that they are unhelpful for fertility so I’d rather not take the risk. Research into their safety is very contradictory, with many studies saying that they are safe, but a few others saying that they are not safe, for example linking consumption of aspartame to risk of premature birth and there is strong evidence that sodium cyclamate affects the urinary tract and saccharine crosses the placenta. Sucralose and sugar alcohols like malitol or xylitol may be safer options but it still seems to me that you should try to keep intake of these low.
• Personally, I would keep sugary foods to a minimum to avoid swings in blood sugar level and only drink fruit juices which are diluted with plenty of water.
• Personally, there are chemicals that I avoid in shampoos etc e.g., methyl and ethylparaben and pthalates because some sources say that they reduce fertility. I also decided not to dye my hair (bleaching, light colours and highlights are safer), because dark coloured dyes (no matter what claims they make about having no peroxide or ammonia or whatever) contain chemicals which can be absorbed all the way through your body into your bladder – and that is just too close to baby for me to feel that it’s a good idea. I try to avoid BPA (a feminising hormone that is in plastics and the lining of food tins – but its very hard to do so because its hard to find out which cans are BPA free - but my understanding is that most food tins contain BPA. I also gave up tuna fish because its mercury content is more variable than say, mackerel.
• I have been asked before for suggestions about what to do with darker moustaches that seem to appear in pregnancy (particularly around the end of the first trimester). Personally I would stick to facial bleach and use it cautiously i.e., put some bleach on and if it starts to feel warm, wash it off with cold water then wait until your skin is completely calm again before having another go and repeating as necessary – on the basis that I want my whole body as calm as possible.
• Where there are avoidable things that you are allergic to e.g., a friend’s cat, you may want to try and minimise exposure especially during stimms, 2ww and early pregnancy - purely on the grounds of keeping your levels of inflammation as low as possible. If you normally take antihistamines to deal with an allergy, you should speak to your consultant about whether they are safe to continue to take when you may get/be pregnant.
• Some ladies choose to eat brazil nuts (see Selenium under Supplements, above) in the two week wait. Other ladies choose to drink pineapple juice, but I’m not convinced about that one.

When should I do a pregnancy test?Many IVF clinics suggest waiting until at least 14 days after embryo transfer and then using a home urine test. They discourage ‘early’ testing because they have no interest in early losses/early biochemical pregnancies, but this is not the case for immune docs. Most immune docs recommend testing by a blood test (betaHCG) about 14 days after EC, and if this is positive, following up with a second blood test 2 days later. The second test is to check that your HCG levels are rising as they should do in a healthy pregnancy. They should rise by at least 66% in 48 hours (or to double in 72 hours). If you cannot get the tests done exactly 48 hours apart, then tests done at a slightly different interval can be interpolated (mathematically corrected) to estimate the value at 48 hours – there are several HCG calculators on the internet to do this. Testing early this way, is important for immune patients:
the sooner you know you are pregnant, the sooner you can get your consultant’s advice on any immune tests/treatments (e.g., drips) that may take time to organise, and this timing may be more urgent in early pregnancy;
abnormal rises in HCG may indicate a problem e.g., an ectopic or molar pregnancy that needs to be addressed urgently;
if unfortunately the pregnancy does not proceed, your consultant will have gained some information that may inform his future treatment for you.
Dr Beer used to advise using a urine test stick each morning starting a few days after embryo transfer but then watching the stick for around an hour in case there was any hint of a line – as that might give information to help determine whether you are dealing with repeated very early losses or not. You could still do this, particularly with a sensitive brand like First Response but it may be pretty stressful as clearly the first few tests could be positive due to HCG from the trigger shot, then if you do get pregnant you could see several days of negative tests first before the positive. Having a blood test seems less stressful to me and a lot more accurate as urine test sticks are not designed to be used in this way.
Your consultant may advise you to have further b-HCG tests until your first heartbeat ultrasound scan.
