The most important
thing for you, if you have a chronic condition, is to have an
understanding of birth control methods and how they can affect your
health. Some of these methods can present specific concerns for
certain rheumatic conditions. If you have antiphospholipid syndrome
or antiphospholipid antibodies in your blood, lupus or RA, here is
what is known about the concerns and the appropriate birth control
methods.
Antiphospholipid antibodies and
antiphospholipid syndrome: APL
or antiphospholipid antibodies are proteins that affect the balance
in the blood between clotting and bleeding and are a risk factor for
blood clots. APS or antiphospholipid syndrome, is an autoimmune
disorder that is characterized by antiphospholipid antibodies, blood
clotting, and miscarriages and the syndrome can happen alone or with
lupus, even though you have the antibodies you may not have lupus.
If you have
antiphospholipid antibodies you are more likely to develop blood
clots if you have another risk factor for blood clotting such as a
severe illness, surgery, prolonged bed rest, malignancy, or pregnancy
or it can be a lifestyle risk factor such as smoking or using
combination contraceptives. That's why this second risk factor can
be one of the variants in the blood that makes clotting possible.
When you have lupus and antiphospholipid antibodies you are more
likely to have other medical risk factors for a stroke or heart
attack, like migraines, atherosclerosis or clogged arteries, or
elevated cholesterol levels.
Contraceptives
with estrogen are know to increase the risk of blood clots and when
you have moderate to high antiphospholipid antibodies you should stay
away from combination hormonal contraceptives. If you have low or
borderline levels of the antiphospholipid antibodies, it may depend
on whether you have had other risk factors for blood clots, to
determine if you should stay clear from the combination hormonal
contraceptives. Progesterone-only contraception is a good
alternative for you if you have antiphospholipid antibodies and are
unable to safely take estrogen. This method is also an effective way
to decrease the heavy menstrual flow if you are on blood-thinning
medications like warfarin, also known as Coumadin, which is often
used to treat APS, Antiphospholipid syndrome.
Systemic lupus erythematosus:
It was thought for many years that estrogen increased disease
activity in lupus. This assumption was based on the findings in
laboratory animals, and the fact that lupus is found mostly in women,
4 out of 5 people with lupus are women, and the reports of birth
control pills and pregnancy where women said their lupus got worse.
There are early reports that suggested there was an increase risk of
lupus flares with the use of contraceptives containing estrogen.
But, there are more recent studies that were better-designed, using
large numbers of participants and standardized methods of measuring
flares that found that estrogen-containing contraceptives are safe in
some women with lupus.
And there were two
randomized clinical trials published at the end of 2005 that found
combination birth control pills don't significantly increase the risk
of flares in women with inactive or stable, moderate lupus. The
Safety of Estrogens in Lupus Erythematosus National Assessment, or
SELENA, trial included 183 women with inactive or stable, moderate
lupus and compared the effects of a standard combination birth
control pill with the effects of an inactive placebo pill. Women who
had active lupus, a history of blood clots, or antiphospholipid
antibodies couldn't take participant in the study and the number and
severity of the lupus flares showed no difference in the two groups.
There was another study of 162 women with stable mild-to-moderate
lupus that also found no adverse effects on flare rates whether the
women used a combination pill, a progesterone-only pill or a copper
IUD.
Based
on these studies, it would appear that combination pills are safe for
you if you have inactive or stable, moderate lupus and don't have
antiphospholipid antibodies. Remember, though, that you may not even
be able to tell how active your lupus is and often lupus activity can
only be detected through blood test or other tests. So if you have
lupus and you want to use a combination pill, your rheumatologist
must be involved in the decision making. Since about 1/3 of the
women with lupus have antiphospholipid antibodies, you have lupus you
should be screened for the antibodies before starting a combination
birth control pill.
It seems that it
would be smart for you if you have lupus to avoid the contraceptive
patch, Ortho Evra, given the recent FDA warning that it increases the
risk of blood clots above that of combination pills. There's also
the birth control pills that contain drospirenone, Yasmin, Yaz, that
are more likely to elevate blood levels of potassium, an important
consideration for you if you have lupus-related kidney problems. The
safety of IUDs, if you are taking immunosuppressive drugs to treat
your lupus, is not certain, because the drugs and the IUDs can raise
the risk of infection. If you have active lupus, barrier methods or
progesterone-only contraceptives are your options. Depo-Provera
injections may be a problem if you are taking corticosteroids,
because both the Depo-Provera and the corticosteroids increase the
risk of bone loss.
Rheumatoid arthritis:
There are some who believe that if you have RA you might actually
benefit from treatment with estrogen-containing birth control pills
because your symptoms improve during pregnancy. But, there's little
research into using the pill to treat RA and research does suggest
that women with RA have normal estrogen levels but lower than normal
androgen levels, so hormonal therapy attempts have focused on
supplementing androgens (androgens are primarily male sex hormones,
but women have small amounts of them), with mixed results and no
clear benefit. Postmenopausal estrogen therapy has also been studied
in women with RA but showed no effect on the activity of the RA, and
although there are no grounds for saying that combination hormonal
contraceptives reduce the activity in Ra, there's no evidence that
suggest their use would make a flare more likely to happen.
Combination pills or the patch, may be effective and convenient for
you if you have RA, but there is a concern that the risk of blood
clots from the patch is higher than the risk from the pill.
Inserting a vaginal ring or a diaphragm may be difficult if you have
severe RA and like with lupus, it's not sure how safe IUDs are if you
are taking immunosuppressive drugs such as ethotrexate,
corticosteroids, or cyclosporine to treat their RA. There are no
studies that have addressed this question specifically with newer RA
medicines such as the biologics, among them Enbrel, Remicade and
Humira.
There are other
concerns as well and they are the hormone containing contraceptives
can interact with other medicines, and this can reduce your
medicine's effectiveness or increase its side effects. Some of these
medicines are used to treat arthritis and related conditions. Some
anticonvulsants like anti-seizure medications that are used to treat
seizures, headaches, or chronic pain disorders may decrease the
effectiveness of birth control pills. There are also,
corticosteroids, warfin, and cyclosporine that can interact with the
contraceptives even though the interactions are weak. Other
medications that are used to treat other health conditions, some
antibiotics, may also interact with hormone containing contraceptives
and if you are using one of these contraceptives you should always
remind your doctor of that fact when your doctor prescribes you new
medications.
When
you have rheumatic conditions and you have to stay in bed for a
while, maybe because of a flare-up of the condition, or after surgery
you should stop using combination birth control pills, the patch and
the vaginal ring. Also, and especially if you have antiphospholipid
antibodies, your doctor should give you low doses of a blood-thinning
medicine. If you are planning elective surgery, you should talk to
your doctor about stopping you combination hormonal contraceptive two
months in advance, because estrogen's effects on blood clotting takes
up to six weeks to reverse.
There are so many
different types of birth control available to you today that if you
have a rheumatic condition you can choose a safe and effective
method. There are also many factors that have to be taken into
consideration and it's essential that you, your gynecologist, and
your rheumatologist work together to decide which of these methods is
best for you.
