Use of Hormonal Contraceptives Linked to Brain Cancer

by Susan Dammann, RN, LAS, Medical Specialisthormonal contraceptives

Does your center provide information about the possible side effects and risks of various birth control methods? If so, you may want to consider including the following information in your materials.

A Jan. 22 article published in Medscape News on January 22, 2015 discussed a study done in Denmark which found an association between hormonal contraceptives and an increased risk for glioma in younger women. The results were published in the print edition of the British Journal of Clinical Pharmacology. The reported risk increases with the duration of use, the study showed. "A nearly two-fold increased risk of glioma [a common type of primary brain tumor] was observed among long-term users of hormonal contraceptives."

The researchers highlight the fact that progesterone exposure was associated with the highest increased risk for glioma in their study. While the study had many strengths, its weaknesses are being identified, but are not expected to alter the results significantly.

"Oral contraceptives are known to influence the risk for certain cancers, but few studies have examined any link to central nervous system tumors", said David Gaist, MD, from Odense University Hospital and the University of South Denmark. He added that although the findings of this study must be interpreted with care, "We feel it is an important contribution and we hope that our findings will spark further research on the relationship between female hormonal agents and glioma risk."

IUD Usage in Adolescents

A recently released policy statement by the American Academy of Pediatrics encourages Pediatricians to counsel adolescent patients regarding contraception in order of effectiveness. The most effective contraception is the progestin implant and the second most effective device is the intrauterine device, or IUD. Historically, IUDs were not used in nulliparous women (those who had not previously given birth), nor in women outside of a monogamous relationship. The uterine cavity is usually larger in women who have already carried a pregnancy and it was believed that a smaller uterine cavity would not tolerate a foreign object well, expelling the IUD and increasing the risk of pregnancy. The concern for women who were not monogamous was the increased risk for sexually transmitted infections that could develop into pelvic inflammatory disease.

Additionally, patients who believe that life begins with conception, need to be counseled that although the chemicals included with the IUD (copper or progestin) are designed to inhibit sperm from reaching an egg, IUDs also affect the lining of the uterus, making it undesirable for implantation, if conception does occur.1,2 In addressing the concern of conception occurring with an IUD in place, the Technical Report of the Academy of Pediatrics simply skirts the issue like this:

"The primary mechanism of action of both types of IUD is preventing fertilization by inhibiting sperm motility. The levonorgestrel IUDs also thicken cervical mucus. All mechanisms occur before implantation, when pregnancy begins, and inhibiting implantation is not believed to be a primary mechanism of action for either type of IUD."3

The report does not leave room for personal opinions and beliefs about when pregnancy begins, but simply states that pregnancy begins with implantation. Since the copper IUD, Paragard, is approved for use as an emergency contraception, there is even more concern for those who view the IUD as an abortive method of birth control. Paragard is reported to be 99% effective in preventing pregnancy,4 if inserted up to five days following unprotected intercourse.3 Medical Institute's greatest concern for IUD use in teens is sexually transmitted infections, which can lead to pelvic inflammatory disease and infertility (the inability to achieve pregnancy when desired). This concern is addressed in most of the current literature, but is not seen as a contraindication for IUD use. Interestingly, the CDC's fact sheet on PID6 lists the following risk factors for PID:

  1. Have an STD and do not get treated;
  2. Have more than one sex partner;
  3. Have a sex partner who has sex partners other than you;
  4. Have had PID before;
  5. Are sexually active and are age 25 or younger;
  6. Douche;
  7. Use an intrauterine device (IUD) for birth control

Just being a sexually active teen is a risk factor for PID. When the IUD is inserted, a second risk factor is added. Another CDC Fact Sheet, "Sexually Transmitted Infections Among Young Americans", points out that "many young people have multiple sex partners", indicating that risk factors numbers 2 and 3 for PID might also be a concern. And finally, the Fact Sheet mentions that many infected teens are often unaware that they have an STI and have not had the proper screening for Chlamydia, indicating risk factor number 1. With five out of seven risk factors for PID specifically being a concern among teens, one must wonder about any recommendation for IUD use in youth.

The American Academy of Pediatrics Technical Report continues the mixed message with statements like this: "...past associations between infertility and IUD use among nulliparous women were attributable to STIs rather than IUDs"3(page e1262) and the CDC Practice Recommendations states, "Although women with STDs at the time of IUD insertion have a higher risk for PID, the overall rate of PID among all IUD users is low."5

The answer to the problem of STIs from both the CDC and the Academy of Pediatrics is condoms. Both organizations recommend that all patients be counseled on the use of condoms, regardless of their choice of contraception to help prevent STIs. However, in 2013, only 8.8% of sexually active high school students reported using condoms along with another method of birth control8, perhaps indicating that with the fear of pregnancy gone, there is little motivation to use condoms.

Fifty percent of all new cases of STIs occur in young Americans from 15–24 years of age. Ignoring the increased risk for PID and resulting infertility for the sake of preventing teen pregnancy is not in the best interest of our youth. Therefore, MI does not agree with the recommendation for IUD placement in adolescent girls.

Letter to Editor: Dr. John W. Volk to Greeley (CO) Tribune

Revised name and logo
Dr. John W. Volk's response 
"Plan B and other Important Things"
On January 30, 2013, John W. Volk, M.D.  submitted the following letter of response to the Greeley Tribune.  As of this date it still has not been published.  The letter was a respectful response to an article published in the Tribune regarding the Board of Weld County Commissioners who had voted against providing emergency contraception to Weld County citizens. 
Dr. Volk is a valued member of 
The Resource Center's Medical Advisory Board.

Because we can - should we? A wise society asks that question of every new technology. That is the question the Weld County commissioners have chosen to grapple with in their decision not to fund emergency contraception in county health clinics.

 

After intercourse, sperm can unite with an egg in the fallopian tube within hours. If that union occurs, an amazing process then begins by which chromosomes from the father and mother are joined together and a new cell is formed. This living cell contains its own complete set of chromosomes different from father or mother. These will determine gender, eye color, temperament and all the many characteristics that will make this individual unique. This is not a potential human being - it is a human being with potential. This is exactly what a young human is supposed to look like on its first day of life. Now, this cell divides and multiplies and begins a six day journey which will end in nestling into the wall of its mother's womb. Here this new life will grow for 9 months until it is time to make its next journey - birth.

 

Emergency contraception works by blocking the surge of hormones which stimulate ovulation (the extrusion of an egg from the woman's ovary). If ovulation is prevented, pregnancy can be avoided. What is less clear, however, is what happens if the medication is taken after that hormone surge or after ovulation has already occurred. Scientists have come to differing conclusions about this and serious moral concerns have been raised about whether, in some cases, emergency contraception might lead to the loss of a fertilized egg - a life. This moral concern lies at the heart of the Weld commissioners' considerations.

 

The idea of emergency contraception leads us to look at a much larger and more important issue. The nature of the sexual act is twofold: 1) to form a bond that will help unite a husband and wife together and 2) to beget life. The bond helps create the stable environment so necessary to welcome new life. When modern society embraced the technology of contraception, the sexual act was redefined in a radical and fundamental way. This technology designed to prevent pregnancy allowed for sex without consequences - no babies, no commitment. This redefinition of the sexual act has produced far reaching and painful effects in our culture.

 

Sex without consequences demands the availability of abortion. The emergence of "the pill" in the 1960's led to a call for the legalization of abortion within a decade. January 22nd marked the fortieth anniversary of Roe vs. Wade. In those 40 years, over 50,000,000 abortions have been performed in America.

 

For nearly 250 years in our country, until slavery was abolished by the 13th Amendment, it was legal for a white man to own a black man - legal, but not moral. The black man was seen as sub-human or not human at all. We look back at those times and wonder how their thinking ever could have been so misguided. A future generation will look back on this era and wonder the same thing about us.

 

For such a future time to come to pass it will require something far more difficult than the overturning of legalized abortion - it will require a change of the human heart. It will mean recapturing the true meaning of sexual intimacy and restoring it to its proper place within marriage alone. So difficult - but the possibility awakens in us great hope.

New ulipristal treatment not the answer

By Julie Lynch McDonald, Pharm.D. • Craig, Alaska

Despite the abundant availability of sterilization procedures, male and female condoms, spermicides in the form of gels, creams, foams, and films, sponges, cervical caps,diaphragms, copper and hormonal IUDs, a plethora of hormonal contraceptive drug combinations available as tablets, patches, vaginal rings, implants, and injections, and three approved “emergency contraception” tablets, half of all pregnancies in the United States are still unplanned. 

What is the solution? According to the Population Council, it is another contraceptive drug regimen.

This commentary is written to briefly evaluate an article titled, “Vaginal ring delivery of selective progesterone receptor modulators for contraception,” written by Dr. Jeffery T. Jensen of Oregon Health and Science University and published in Contraception1. To provide some background, research is being conducted on the use of a drug called ulipristal—the active agent in ella®—through a ring inserted vaginally to prevent pregnancy by inhibiting ovulation.

This research is being conducted by the Population Council, which was founded in 1952 with the stated mission of helping “achieve a humane, equitable, sustainable balance between people and resources.”

Ulipristal belongs to a group of drugs called Selective Progesterone Receptor Modulators (SPRMs). The first SPRM approved for use in the United States was mifepristone, which is commonly known as “the abortion pill.” Mifepristone is effective at terminating implanted, growing pregnancies due to its ability to block progesterone, an essential hormone for pregnancy. Blocking of progesterone by mifepristone results in fetal detachment from the placenta, which is followed by vaginal expulsion of the fetus.

SPRMs such as ulipristal and mifepristone can both suppress ovulation as well as terminate implanted pregnancies. The manner in which they act depends primary on the timing of administration (when it is taken within a woman’s cycle), and potentially the serum concentration (amount of drug in the body).

Upon review of Dr. Jensen’s article, there are two primary concerns. First, women will be given a drug marketed to prevent contraception that also possesses an established capability to terminate implanted pregnancies. Second, SPRMs such as ulipristal have questionable safety for women, especially with long-term use. Both concerns will be briefly discussed in the following paragraphs under the topic headings, “Risk to Pregnancies,” and, “Risk to Women.”

Risk to Pregnancies

Dr. Jensen’s article stated that 32% of test patients (25 out of 78 women) still ovulated despite the use of ulipristal vaginal rings. There was no discussion on if pregnancies occurred in the 25 women who ovulated, nor was there a description of the outcomes for these pregnancies if any did occur. The future goal was identified to be a tripling of the dose of ulipristal given to women in order to decrease the percent of women who ovulate to 10%, but this is still a high percentage of women who may become pregnant, especially given the following: Ulipristal is proposed to be given on a daily basis via a vaginal ring inserted for three months. Women who do achieve pregnancy despite use of ulipristal, then, will expose their embryo/fetus for two months to a drug known to be “embryotoxic at low doses.”2

Furthermore, since the absence of menstruation is typical in women using ulipristal vaginal rings, women could be unaware of their pregnancy for months. Therefore, beyond the fetal risk from direct daily exposure to ulipristal, the fetus could also be exposed to risky behavior (including drug and alcohol use), and denied standard prenatal care simply because the mother is unaware of her pregnancy.

None of these concerns were addressed in the article.

Risk to Women

There are two key risks to women posed by use of SPRMs. The first risk is infection, which is increased due to a suppressed immune system and the potential for a deceased fetus, which would serve as a medium for bacterial growth prior to its vaginal expulsion. The second risk is related to changes in the lining of the endometrium, or wall of a woman’s womb.

SPRMs are well-documented to produce antiglucocorticoid effect, which means they suppress the immune system. The Department of Health and Human Services’ Emerging Clostridial Disease Workshop found that mifepristone’s effect on the immune system resulted in the “clinical findings of rapid fulminating lethal shock syndrome” that was neither preventable nor treatable.3 It is established that ulipristal has a “high affinity” for progesterone and glucocorticoid receptors. The concern for ulipristal to have antiglucocorticoid effects was mentioned in the article, but no evaluation of this concern was provided.

Dr. Jensen’s article stated SPRM-associated endometrial effects “were frequently observed,” and were reported in 41% of women using the ulipristal ring. Since the endometrial effects such as endometrial hyperplasia or cancer are dose-dependent, it is reasonable to assume higher concentrations of ulipristal will result in a higher incidence of this adverse effect. Therefore, in the future it can be expected to have a greater risk when the dose is tripled in an effort to increase the percentage of women who will not ovulate. According to the article, a six-month study is being conducted to evaluate the long-term safety of using ulipristal vaginal rings, but this timeframe is unrealistically short.

In conclusion, development of SPRMs has been highly controversial due to their innate ability to terminate implanted pregnancies and the risks they pose to women. Nonetheless, SPRMs have been rushed through the FDA approval process under the subpart H, which is a fast-track reserved for “new drugs to treat serious or life-threatening diseases.”4

The push to develop ulipristal as “contraception” is being completed without evident concern for fetal effects and in an apparent absence of appropriate communication to patients about ulipristal’s ability to terminate implanted pregnancies.

Concern for the risk to women due to ulipristal appears to be secondary to the priority placed on preventing unplanned pregnancies. While a goal of reducing unplanned pregnancies is commendable, realistically, unplanned pregnancies will never be completely eliminated—and maybe they shouldn’t be. When did unplanned pregnancies become equivalent to horrific diseases like cancer or the plague that would be worthy of risking women’s health and exposing fetuses to toxic agents?

As a pharmacist and a woman, I hope the scientific community can begin to take a more proactive approach to solving unplanned pregnancies, rather than continually pushing for chemical solutions that pose an often under-reported and under-studied risk to women and their fetuses.

What’s wrong with contraceptives?

By Amy Scheuring, Executive Director, Women’s Choice NetworkBirth Control Pills

The recent barrage of news coverage following Susan B. Komen for the Cure’s proposed defunding of Planned Parenthood, as well as the Roman Catholic Church’s response to President Obama’s proposed healthcare mandate have many wondering: What’s wrong with contraceptives?

For over 50 years, we’ve heard that pills, injections, devices, and hormones will prevent “unwanted” pregnancy, protect women’s health and stop everything from AIDS to acne, creating a happy, healthy, and sexually fulfilled generation of men and women.  

After more than 40 years of government-subsidized contraceptives, why shouldn’t we welcome additional healthcare packages that require an assortment of miracle drugs and preventative hormones to be offered by every employer? Part of the answer lies in the stunning facts about the collective failure of these products to deliver on their promises:

  • According to Planned Parenthood’s Guttmacher Institute, 53% of women obtaining an abortion were using birth control when they got pregnant.  
  • At the Women’s Choice Network Centers, almost 65% of our pregnant clients were using birth control when they got pregnant.
  • Hormonal birth control methods do not prevent STIs or AIDS, and condoms are virtually useless against many viral forms of STIs, such as Human Papilloma Virus (HPV).
  • Teens using birth control pills and injectables feel safer, leading them to engage in sex more frequently than peers who are not using birth control.
  • One highly touted study indicates that 99% of sexually active women ages 15-44 have used at least one form of birth control, but the fact remains that half the pregnancies in the U.S. are still “unintended.”

As we consider whether our future health care should include contraceptives, let’s remember that many who suffer because of a previous abortion or STI have relied on their false promises. The pursuit of true sexual intimacy—joyfully building a family and strengthening a lifetime commitment—has been replaced by a false notion that, given the proper health care, we can control or eliminate the inconvenient “outcomes” of sex.  

So, what’s wrong with contraceptives? Before we even enter into the moral, economic, or social arguments, the answer is clear: They simply don’t work as promised.

While contraceptives entrench themselves as the gateway drug to abortion, birth control proponents are still stuck in the mid-20th century, clinging to the hopeless assertions that if we just spend more, educate earlier and use birth control “better,” the desired outcomes will one day kick in.

After four decades of government-funded birth control, and all our best efforts to create a world where sex has no consequences, are we any better off? You decide.
