Researchers followed 68 women who attended the Family Welfare Clinic at the Kenyatta National Hospital in Nairobi, Kenya to determine if the low estrogen combined oral contraceptive (OC) Microgynon, a progestogen only OC, and Depo-Provera induce changes in the oral glucose test. These women did not take any steroidal contraceptives before entry into the study. Blood glucose levels were significantly higher after 60, 90 and 120 minutes than the control levels for women taking Microgynon. In addition, the mean areas under the glucose curves were substantially elevated after 1, 3, and 6 months above the control (p.002, .005, and .01 respectively). The only significant change in blood glucose levels in women taking the progestogen only OC occurred at 30 minutes after 6 months. Yet the mean areas under the curve were significantly higher than the control after ,1 2, and 3 months (p.005, .05 and .002 respectively). As for Depo-Provera, significantly lowered blood glucose levels only occurred after 1 month at 30, 50, and 90 minutes although no significant changes occurred after 1, 3, and 6 months in the mean areas under the glucose curves. Metabolic change occurred earlier and more often in Microgynon users than progestogen only OC users. This could be due to the progestogen levonorgestrel which has been shown to interrupt glucose metabolism. These changes could possible adversely effect women who are predisposed to developing diabetes, since 1 woman did develop a diabetic curve after 1 month of using Microgynon. Nevertheless no pattern towards abnormal glucose tolerance existed. Standard deviations of areas under the curves indicated that the number of women who develop glucose intolerance may increase with duration of use.

Patients with a history of recurrent candidiasis and who were using Depo-Provera (medroxyprogesterone acetate, DMPA) for contraception were reviewed in order to determine the time relationship between episodes of proven candidiasis, episodes of pruritus vulvae suggestive of this infection (but unproven), and injection of DMPA. Recently, patients were included in the study who had been given DMPA specifically to prevent recurrences of candidiasis even when the drug's contraceptive action was unnecessary, such as after sterilization. In all cases, the infection was initially treated with a vaginal candidacide, most commonly 1 week of an imidazole. The patients ranged in age from 19-37 years at the time of the 1st injection. Diabetes had been eliminated in all the cases. DMPA was given intramuscularly at a dose of 150 mg every 12 weeks. Prior to 1983, an estrogen supplement was prescribed in most cases in an effort to produce monthly menstrual periods. Estrogen supplementation is no longer used routinely, with amenorrhea the aim, although it is occasionally given to women who experience breakthrough bleeding. Candidal infection was considered proven when the branching filaments of the species were seen on a stained vaginal smear or when the species were cultured in a laboratory from a vaginal swab taken a symptomatic patient. With the exception of 2 patients, clinical candidiasis did not occur within the time in which 150 mg of intramuscular DMPA is known to suppress ovulation in all women, i.e., 12 weeks -- except in the presence of exogenous estrogen (cases 1, 2, and 14) and in one case (15) in which the patient had an unplanned conception prior to the injection. Both patients who experienced clinical despite the use of DMPA alone (cases 8 and 13) asked remain on the drug because believe it was responsible for their longest remissions in the past few years. The study seemed to provide evidence that DMPA will prevent a recurrence of clinical candidiasis in many women who are prone to this condition. The study further indicated that estrogens may predispose women to this infection.

This discussion identifies the risks and benefits of each of the hormonal methods of contraception -- combined estrogen-progesterone oral contraceptive (OCs), progestogen-only pills, and depot progestogen injections. It also explains the use of a profile of risk factors in considering the appropriate prescription for each individual in relation to her contraceptive needs. Information regarding medical risks has come from the consideration of mortality rates in large cohort studies. Looking at categories of the causes of 249 deaths in ever-users of the pill and controls, Layde and colleagues were able to show that there was an excess mortality in the pill group of 40% and that the extra risk was concentrated in cardiovascular causes: myocardial infarctions, cerebral thrombosis, and cerebral hemorrhage constituted the largest proportions. A small proportion of combined OC users may develop clinical hypertension but more suffer a reduction in the high-density lipoprotein (HDL) cholesterol fraction of the blood lipids. Both of these effects tend to increase the risk of cardiovascular complications and both are positively related to the dose of the progestogen components. In prescribing combined OCs, attention needs to be paid to further moves away from the norm towards the extremes: the presence of cardiovascular risk factors and the use of certain longterm medications or the presumptive designation as a "rapid metabolizer." An analysis of progestogen only pill (POP) users in the Oxford-Family Planning Association study confirmed the reasonably low rates of accidental pregnancy in POP users. There is a marked reduction with increasing age, and it is significant that many prescribers are now giving POP to older women for whom combined OCs are contraindicated because of cardiovascular risks. It also seems reasonable to use them in women with some medical disorders, for example, recurrent pulmonary embolism, hypertension, and diabetes. Initially, depot injections of progesterone were developed to provide a long-acting or sustained-release type of drug administration to assist users of the progestogen-only method which, unlike combined OCs, does not make use of regular drug-free intervals. In practice it has been found that the effectiveness against pregnancy is enhanced and the side-effects are increased in giving progestogen by depot injection. The 2 preparations currently licensed in Britain are Depo-Provera (medroxyprogesterone acetate) and Noristerat (norethisterone enanthate). In some cases proper and clear information may not have been given to the patient and proper consent not obtained before giving the drug. This problem is magnified because of the occurrence in some women of disturbed bleeding patterns, especially if given immediately after childbirth or an abortion. Also, in a small proportion of users anovulatory amenorrhea may supervene for some months or even as long as 2 years following depot injection.

Prescribing contraceptives to diabetic women requires cognizance of metabolic effects and the risks of type I or type II and gestational diabetes mellitus (GDM) in prediabetic women. Studies have show that poor maternal glycemic control in the 1st trimester in diabetic women has resulted in a twofold to threefold increased risk for congenital malformations. A reduction from 6.6% to 1.1% in malformations could be realized by euglycemic control before conception and during the first 8 weeks of gestation. A low-estrogen preparation should be selected and blood pressure should be monitored regularly. Progestins adversely affect carbohydrate and lipid metabolism, as they decrease glucose tolerance by increased insulin resistance, thus the selection of proper progestin dose/potency is important in prescribing OCs. The lowest-dose OCs may be prescribed under close medical supervision to women with insulin-dependent diabetes mellitus (IDDM) without serious vascular complications. Patients should be evaluated after the 1st cycle of OC use and every 3-4 months thereafter with monitoring of weight, blood pressure, postprandial glucose, and glycosylated hemoglobin levels. Women with prior GDM should be evaluated annually utilizing a 2-hour, 75-g glucose tolerance test (OGTT) at the postpartum visit. For OCs, a low-dose estrogen ( 0.05 mg ethinyl estradiol) and a low-dose/potency progestin (or = 0.50 mg of norethindrone or or= 0.100 mg of levonorgestrel) should be selected. The safety of prescription of OCs to women with type II diabetes is unclear, but a supervised program similar to that of IDDM patients is recommended. Currently neither of the long-term contraceptives, depo-medroxy-progesterone acetate (Depo-Provera) injection or the levonorgestrel-containing implant, Norplant, are recommended as first-time methods for women with diabetes. On the other hand, the IUD is an effective, reversible method, particularly for older women with hypertension, provided antibiotic prophylaxis is undertaken at the time of insertion.

The US Food and Drug Administration finally approved the injectable contraceptive Depo-Provera (DMPA) in October 1992, 25 years after its introduction. Women return to a health facility every 90 days for an intramuscular injection of 150 mg DMPA, which provides them 99% effective contraception. Menstrual changes and spotting are the leading reasons for DMPA discontinuation. Eventually, more than 50% of DMPA users develop amenorrhea. During the first year, women gain about 2 kg and weight increases as time passes. Weight gain is the second leading reason for DMPA discontinuation. DMPA may adversely affect glucose tolerance in women at risk for diabetes, but it does not affect cardiovascular or metabolic functions. It may increase the risk of osteoporosis. A rare side effect is convulsions. 1-10% of DMPA users have other central nervous system effects, such as headaches, dizziness, and depression. Itching and rashes may develop. Fertility returns within 1 year after discontinuation. DMPA is linked to low birth weight. It apparently does not harm breast-fed infants or hinder lactation. A World Health Organization study shows that DMPA users less than 35 years old experience a slight increase in breast cancer but a reduced incidence of endometrial cancer. Nurses are instrumental in guiding women as they choose DMPA and in informing them about its potential side effects, including breast cancer risk. They must screen women for pregnancy and evaluate their risk of breast cancer. They must determine whether women are able to return every 3 months for DMPA injections. Women who select DMPA must use other contraception, e.g., barrier protection, within the first 24 hours after initial injection. Nurses should counsel them about the likely menstrual changes to reduce the likelihood of dissatisfaction. They should recommend a daily dose of 1200 mg of elemental calcium and daily exercise of long bones to minimize the risk of developing osteoporosis.

Menorrhagia--menstrual periods lasting longer than 7 days and totaling blood losses greater than 80mL--affects 9%-14% of otherwise healthy women, and it can signal cancer, an endocrinologic disorder, or gynecologic disease. Blood loss can be high enough to result in anemia, fatigue, and syncope. Most often, abnormal uterine bleeding such as menorrhagia involves a disruption in the hypothalamic-pituitary axis, the ovary, and/or the uterus. Other identified causes include medications (especially psychotropics) that cross the blood-brain barrier; chronic diseases such as cancer, diabetes, and liver and kidney dysfunction; endocrine disorders, perimenopausal anovulation, polycystic ovary disease, pituitary tumors, and abnormal estrogen cycling caused by morbid obesity; and anatomic abnormalities of the uterus. Routine tests include hematocrit or hemoglobin to detect and evaluate anemia, thyroid stimulating hormone (TSH) level to evaluate thyroid function as a possible cause, and a pregnancy test to rule out an incomplete, spontaneous abortion as a cause. A Pap test is recommended to screen for dysplasia that can suggest a gynecologic cancer cause. Additional screening for endocrine disorders that may be causing menorrhagia include tests of thyroid, liver, and kidney function, and tests of follicle stimulating hormone (FSH), prolactin, and cortisol levels. Treatment can be medical or surgical. Medical treatment includes prostaglandin inhibitors, specifically nonsteroidal antiinflammatory drugs (NSAIDs), and hormonal therapy with estrogen, progesterone, gonadotropin-releasing hormone agonists, or oral contraceptives such as medroxyprogesterone (Depo-Provera). Surgical treatment includes hysteroscopic endometrial ablation by physical agents, laser electrodiathermy, and "roller ball," or surgical, resection. Hysterectomy is the treatment of last resort.

The use of depo-medroxyprogesterone acetate (DMPA), or Depo Provera, has been debated for the 20 years since it became available in 1967. The US Food and Drug Administration (FDA) refused to approve Depo Provera on the basis that it caused breast tumors in a controlled study of Beagle dogs and Rhesus monkeys conducted by Upjohn, the manufacturer. Depo Provera has been approved in over 60 other countries and is in use in 30 or 40 others with an estimated total of almost 5 million users. A natural hormone, progesterone, DMPA is injected intramuscularly and absorbed slowly. Common dosage is 150 mg every 3 months and usually is administered during the 1st week of the menstrual cycle. The pregnancy rate with Depo Provera is .44 pregnancies/100 women years for women receiving 100 mg every 3 months. No pregnancies were recorded in recent studies for women receiving 150 mg. Possible side effects include amenorrhea, weight gain, dizziness and headaches. The median time for contraception after the presumed duration of one's last injection is 5-1/2 months. Some countries only permit women who already have 1 child to use Depo Provera. The FDA in the US approves the use of Depo Provera for treatment of endometrial and renal cancer but accuses it of causing cancer in Beagles and Rhesus monkeys. The studies were conducted over 7 and 10-year periods, respectively, with extremely negative results including the death of 3 dogs due to "drug-induced diabetes," atrophication of adrenal glands, and malignant tumors. There were similar results for the monkey study. In the UK, the Committee for Safety in Medicine supports Upjohn's view that Beagles are unsuitable for comparison testing because "all dogs are acutely sensitive to progesterone." Groups such as the National Women's Health Network, the institute for Food and Development Policy, and "Mother Jones" have used the media to generate opposition to Depo Provera, citing a double standard for rich and poor women, developed and less developed countries. The proponents of Depo Provera criticize health activists for imposing their own standards on women in developing countries. Regarding concerns about greater risk of Acquired Immune Deficiency Syndrome (AIDS), Depo Provera can be injected with disposable needles. In response to the controversy, Upjohn withdrew its application to the FDA in September 1986 but intends to resubmit with new information from a World Health Organization report, which showed no evidence of an increased risk of cancers of the endometrium, liver, or breast.

The author describes a range of contraceptive methods, and their side effects, which may be acceptable for new parents. The methods are the oral contraceptive pill, Norplant, Depo-Provera, and intrauterine devices (IUD). Natural methods and permanent contraception are options described in insets. The author notes that differences in the effectiveness rates among available types of oral contraceptive pills are small enough not to merit consideration when deciding which kind of pill may be appropriate. Combination birth control pills are taken daily at the same time for 21 out of 28 days. Combination pills are not recommended for women with a history of hypertension or other cardiovascular diseases, thrombophlebitis, migraine headaches, diabetes, active gallbladder disease, or mononucleosis. Any hormonal method may be particularly risky for smokers over age 35. The mini-pill, containing a smaller amount of progesterone and no estrogen, is taken every day and is also on a 28-day cycle. Containing no estrogen, the mini-pill is often recommended for women who are nursing, who are over age 35, or who suffer from hypertension or migraines. Both adverse and positive side effects may be experienced from use. Norplant is the brand name of a contraceptive system which releases progesterone from under the skin of a woman's upper arm over the course of a five-year period. The system has a theoretical effectiveness rate of more than 99%, although the duration of effectiveness may be less than five years in overweight women. The most common side effect is irregular bleeding, and removal is often a longer and more difficult procedure than insertion. The most commonly used injectable hormonal contraceptive is Depo-Provera, a progesterone solution which works for up to three months. The majority of users experience some side effects. Finally, IUDs are highly effective and need to be replaced only every 1-10 years depending upon how they are made. Women typically experience discomfort during IUD insertion, and they should not be used by women under age 20 years, who have never had children, or who have ever had a pelvic infection.

There are hormones from 2 sources which determine the menstrual cycle. The pituitary produces luteinizing hormone and follicle stimulating hormone and the ovaries secrete estrogen and progesterone. For clinical use, a cheap source of progesterone has been found in the Mexican yam. Since the 1st oral contraceptives were tested in Puerto Rico in the late 1950s, there has been a trend toward reducing the dosage. Estrogen prevents ovulation in 95-98% of patients. Other factors are also involved. Although it is estimated that 80-100 million women in the world today use oral contraceptives, this method is not always followed for long periods. From 25 to 60% discontinue the use within the 1st year. Increased risk of unfavorable side effects occurs in those with high blood pressure, migraine headaches, diabetes, epilepsy, undiagnosed genital bleeding, or gallbladder disease. Women over age 40 run a greater risk of heart attacks. Intravenous blood clots are the major risk. Severe abdominal, chest, or leg pains, severe headaches, and eye problems may be symptoms of blood clots. With the 21-day package the user takes a pill a day for 3 weeks and then none during menstruation. The sequential type of medication is no longer used. Minipills are taken every day. Missing taking pills is the most common cause of failure of the method. Estrogen replacement therapy for menopausal women is a temporary treatment to relieve physical distress. Depo-Provera, containing a long-acting progesterone agent, may be injected every 3 months instead of daily oral contraceptives. When progesterone is used with an IUD it acts locally. Hormones to maintain pregnancy are no longer used. Use of hormones as a test for pregnancy has been discontinued. Estrogen-progesterone injections given to inhibit milk production may cause serious side effects.

This "Ask the Experts" column addresses two concerns related to use of Depo-Provera. The first question relates to the clinical significance of frequent urination. Two of the three experts assert that frequent urination in a Depo-Provera user is unlikely to be related to method use; urinary tract infection and diabetes are more probable causes. The third notes that hypoestrogenicity could be a factor and suggests examination of the vagina for atrophy, which could cause the tissue around the urethra to become atrophic. The second question addresses techniques for confirming menopause in Depo-Provera users. The experts concur that measurement of follicle-stimulating hormone in perimenopausal Depo-Provera users lacks predictive value. Recommended, instead, is continuation of Depo-Provera with supplemental estrogen until the woman is in her mid-50s. At that time, conventional hormone replacement therapy can be initiated.
