Complications associated with IUD use in a family practice setting.

This study compares the complication rate of intrauterine contraceptive devices (IUD) with other contraceptive measures in a residency practice. The study population included 220 randomly selected women who had IUDs inserted by residents over a five-year period. One hundred similarly selected women started on birth control pills (BCP) were used as a control group. Of the IUD patients, 8.6 percent developed pelvic inflammatory disease vs 2 percent of the BCP patients. The incidence of gonorrhea was not significantly different between the two groups: 8.2 percent for the IUD groups vs 7 percent for the BCP group. Discontinuation of IUDs for reasons other than desiring pregnancy was significantly higher than discontinuation of BCPs: 41 percent vs 12 percent. Of the total IUD insertions, there were 21 expulsions (10 percent) and one uterine perforation (0.4 percent). Five pregnancies occurred in the IUD group, yielding a pregnancy rate of 1.7 per 100 women-years. There was a four percent rate of gynecologic hospitalizations in the IUD group as contrasted with one percent rate in BCP group. IUD use in the family practice setting under study is associated with comparatively poor long-term acceptance and a relatively high rate of complications.

Ovarian function after seven years' use of a levonorgestrel IUD.

Fifteen women with regular menstrual periods and seven amenorrheic women who had been using a levonorgestrel-releasing (LNg) IUD for more than seven years were studied. For controls, eight women using TCu380Ag IUDs for more than seven years were studied during two complete menstrual cycles. Ovarian function was assessed with hormonal determination and ultrasound examinations. The regularly menstruating women were studied for two complete menstrual cycles and the amenorrheic women for eight weeks. In the regularly menstruating LNg-IUD users, according to progesterone levels, 93% of the cycles were ovulatory but just 58% of these 'ovulatory' cycles showed normal follicular growth and rupture. Follicular cysts and luteinization of regressing follicles were observed in 42% of the 26 'ovulatory' cycles studied. SHBG capacity was decreased in the LNg-IUD users compared with the TCu380Ag users. Progesterone levels were lower in the LNg-IUD users compared with the TCu380Ag users but this difference was not statistically significant. Preovulatory estradiol and LH levels were lower in the LNg-IUD users than in the TCu380Ag users. These differences were not statistically significant. For the amenorrheic women, five had follicular cysts that disappeared spontaneously within 45 days. Two women showed follicular development and rupture. The presence of good cervical mucus was observed in 69% of the ovulatory cycles studied in the LNg-IUD users. This indicates that effects on cervical mucus cannot be the main mechanism of action of the LNg-IUDs. It is concluded that LNg-IUDs may exert a contraceptive effect in many different ways, such as inhibition of ovulation, endometrial changes preventing implantation, alteration of physical and chemical properties of cervical mucus affecting sperm transport and subtle disturbances in hypothalamic pituitary ovarian function, resulting in alterations of follicular development and rupture.

Comparison of the clinical performance, contraceptive efficacy and acceptability of levonorgestrel-releasing IUD and Norplant-2 implants in China.

The levonorgestrel-releasing IUD (LNG-IUD, 20 micrograms/d) and the Norplant-2 implants were studied in a randomized comparative clinical trial with 200 women for one year. No pregnancy or expulsion occurred with the Norplant-2. In the LNG-IUD group, there was one pregnancy at the 12th month of use after an unnoticed expulsion. The net cumulative pregnancy and expulsion rates of LNG-IUD were 1.0 and 3.0. The removal rate due to menstrual disturbances in both LNG-IUD and Norplant-2 groups was 3.0. The use-related discontinuation rates were 9.0 and 3.0, and the continuation rates were 90.0 and 96.0, respectively. The differences were not statistically significant. Menstrual disturbance was the main side effect. It was improved after long time use, especially in the LNG-IUD group. After one year, the percentages of women with amenorrhea were 18.9 for the LNG-IUD and 8.3 for the Norplant-2. The menstrual blood loss was statistically significantly reduced in the LNG-IUD group, and blood haemoglobin concentration increased in both groups. The LNG-IUD and Norplant-2 are highly effective, safe, long-acting, and well accepted by the Chinese women.

Prostaglandin E2 (PGE2) inhibits an IUD-induced premature luteolysis in sheep.

Fifteen ewes were assigned as they came into estrus to one of three randomized treatment groups: 1. Sham IUD + Vehicle, 2. IUD + Vehicle, and 3. IUD + PGE2 in Vehicle. An IUD was inserted adjacent to the luteal-bearing ovary of unilaterally ovariectomized ewes on day 3 postestrus. Vehicle (Na2CO3) or PGE2 (500 micrograms) in vehicle was given every 4 hours intrauterine through an indwelling uterine cannula from day 3 postestrus until ewes returned to estrus. Luteolysis was advanced in both the Sham IUD and IUD groups receiving vehicle. An IUD-induced premature luteolysis was prevented by PGE based on daily concentrations of progesterone in peripheral blood and the extended interestrous interval. It is concluded that chronic intrauterine injections of PGE2 (500 micrograms) every four hours can prevent an IUD-induced premature luteolysis. It is also concluded that an IUD-induced premature luteolysis is not necessarily through uterine distention.

T-shaped IUD move vertically with endometrial growth and involution during the menstrual cycle.

Ultrasound has been used to detect and evaluate intrauterine device (IUD) position for some years. Different definitions of the IUD in the uterine cavity have been discussed trying to relate them to bleeding and pain complaints. Most of these definitions do not take into account the uterine wall or endometrial thickness. This is a secondary analysis of a previous cross-sectional study, in which 481 IUD users had their T-shaped IUD evaluated by transvaginal sonography. The correlation between the endometrium thickness and the IUD-myometral distance was studied, defined by the linear measurement between the upper end of the IUD and the myometrium/endometrium interface. These two measurements were highly correlated over the entire sample range (r = 0.29) and an even stronger correlation existed (r = 0.66) when only cases below the 90 percentile of the IUD-endometrial distance distribution were considered. These results suggest that the IUD position in the uterine cavity is influenced by the growth and thinning of the endometrium, and that this information should be considered when evaluating the IUD position by sonography.

Randomised controlled trial of prophylactic antibiotics before insertion of intrauterine devices. IUD Study Group.

BACKGROUND: The value of antibiotic prophylaxis before insertion of an intrauterine device (IUD) remains uncertain. We undertook a triple-masked, randomised, placebo-controlled trial to find out whether such prophylaxis reduces the rate of IUD removal within 90 days. METHODS: 11 clinic sites in southern California enrolled women who requested IUD insertion and were at low risk of sexually transmitted infection according to self-reported medical history. We randomly assigned 1985 participants either 500 mg azithromycin or placebo capsules of identical appearance taken about 1 h before insertion of a Copper T 380A IUD. 118 women did not have an IUD inserted. We followed up 1833 of the remaining 1867 (98%) participants for at least 90 days after insertion. FINDINGS: The rate of IUD removal for any reason other than partial expulsion was 3.8% (35/918) in the antibiotic group and 3.4% (31/915) in the placebo group (relative risk 1.1 [95% CI 0.7-1.8]). The two treatment groups sought medical attention with equal frequency (mean 38 visits per 100 women). During the 90 days after IUD insertion, only one woman from each assignment group had salpingitis, as defined by established criteria. INTERPRETATION: Prophylaxis with azithromycin did not affect the likelihood that a woman would retain her IUD at 90 days or the frequency of postinsertion medical attention. In appropriately screened women, the risk of upper-genital-tract infection is negligible after IUD insertion, with or without the administration of prophylactic antibiotics.

A morphometric study on the endometrial activity of women before and after one year with LNG-IUD in situ.

The endometrium was studied by morphometry in 34 healthy women before and after one year's use of an IUD releasing levonorgestrel at a rate 20 micrograms/24 hr (LNG-IUD-20). The effect was compared with that of an IUD releasing 2 micrograms levonorgestrel/24 hr (LNG-IUD-2). The appearance of suppressed endometrial proliferative activity and increased inflammatory reaction was similar in the two experimental groups, suggesting that the morphological alterations were independent of the LNG dosage. The result of this study, combined with clinical data, suggests that LNG-IUD-20 could replace LNG-IUD-2 without any additional side effects. The efficacy of LNG-IUD-20 is also likely to last for a longer period than the LNG-IUD-2.

Ectopic pregnancy and IUDs; incidence, risk rate and predisposing factors.

During a period of 4 years, 1974-77, in Uppsala county; Sweden, 203 women underwent surgery for ectopic pregnancy with histological proof of the diagnosis. For the female population of fertile age this corresponds to 0.11 ectopics per 100 women 15-44 years of age, or 1.08 per 100 notified pregnancies, or 1.53 per 100 births. Fifty-five of the women with ectopic pregnancy were using an intrauterine device (IUD) (48 a copper-bearing IUD and 7 some other type of device), and 6 women used a low dose progestogen contraceptive. For users of copper-bearing IUDs the risk of an ectopic pregnancy was estimated to be 0.15 per 100 women years. When comparing this latter risk rate with the overall incidence rate of 0.11, it must be observed that the populations forming the denominator in these two rates differ with respect to some crucial characteristics. Nulliparity and predisposing factors were found statistically significantly more often in non-IUD-users with an ectopic pregnancy than in IUD-users. Such predisposing factors may be less prevalent in IUD-users, as in other populations. This may explain why ectopic pregnancy has been found to occur less frequently than theoretically expected among IUD-users. The "ectopic preventing" capacity of the IUD may therefore be considerably lower than has been previously claimed.

Management of amenorrhea due to contraceptive injectables by temporary IUD insertion.

Amenorrhea is a common side effect of injectable contraceptive. Lippes loops were inserted in 22 amenorrheic women who continued injectable contraception, and in 6 cases with prolonged postinjectable amenorrhea. The occurrence and rhythm of subsequent bleeding was recorded. IUD insertion induced bleeding in most cases of continued injectable users but it was usually irregular and unpredictable. It was regular in 6 subjects only while the IUD was in situ. After the removal of the IUD, the majority regained the state of amenorrhea within 3 months. Temporary IUD insertion had a positive impact on continuation (a mean additional rate of 18 months of use) among subjects who had wished to terminate the method because of amenorrhea. This procedure of temporary IUD insertion may serve to provide these women with an alternative contractive approach. In the postinjectable amenorrhea group, temporary IUD insertion induced bleeding during IUD application as well as after its removal, which was more predictable than that in the continued users. IUD insertion may facilitate return of regular menses and resumption of fertility in amenorrheic women who stop injectable contraception.

Comparative study of safety and efficacy of IUD insertions by physicians and nursing personnel in Brazil.

To assess whether trained nursing personnel could provide IUD services as safely and effectively as physicians in Brazil, an experimental study was conducted at the main clinic of the Center for Research on Integrated Maternal and Child Care in Rio de Janeiro. From November 1984 through April 1986, a total of 1,711 women who requested IUD insertion at the clinic were randomly assigned to have a Copper-T 200 IUD inserted by one of the clinic's 11 physicians or 13 nurses. All of the physicians and nursing staff members who provided these services had taken the Center's standard clinical family planning training course. Of 860 insertions attempted by the physicians and nurses, 1.3% and 3.3%, respectively, were unsuccessful. Statistically, this difference was very significant (P < 0.01). Also, mainly because the cervix was small and undilated, nulliparous women had a relatively high insertion failure rate of 8.0%, as compared to 1.5% for primiparas and 1.0% for multiparas. The overall rate of complications at insertion was 1.8%, these complications including diaphoresis, vomiting, syncope, cervical laceration, and one case of perforation of the uterus; no significant difference was found between the complication rates for insertions performed by physicians as compared to nurses. However, 9.0% of the study subjects reported severe pain during IUD insertion, with significantly higher percentages reporting pain if the IUD was inserted by a physician, or if the subject was nulliparous, had preinsertion symptoms, or had a history of pelvic inflammatory disease (PID) or sexually transmitted disease (STD). It was also found that the nurses had a dramatically high insertion failure rate (11.6%) with nulliparous subjects, while the physicians' failure rate with such subjects was a significantly lower 3.4%. No significant difference was found in the groups served by nurses and physicians with regard to postinsertion complaints or termination of use within 12 months of insertion. These findings suggest that future training, besides preparing nursing personnel in IUD insertion, should emphasize preparation in taking the client's medical history and diagnosing existing medical symptoms that could be associated with IUD insertion complications. In addition, if a nulliparous woman requests an insertion, it should be performed by a physician or more experienced nursing staff member with close medical supervision. Because of high rates of reported pain at insertion, such women, as well as those with medical symptoms associated IUD insertion complications and those with a history of PID or STD, should be considered candidates for extra care and counseling.(ABSTRACT TRUNCATED AT 400 WORDS)

[Cytologic studies after insertion of intrauterine contraceptive devices (IUD) (author's transl)].

Cervical smears of 554 women using IUDs were examined. The following criteria were evaluated: 1. Age distribution, 2. maturation index of the vaginal epithelium, 3. vaginal flora, 4. cytologic criteria of inflammation, 5. period of time between insertion of the IUD and the cytological examination, 6. final cytologic diagnosis. 554 women without IUD and normal gynaecological status served as a control group. It was the goal of the study to find out, firstly if IUDs in situ produce typical and specific changes in the cytologic pattern and secondly if the rate of suspicious and positive findings is increased: In IUD using women the rate of cases with unphysiologic vaginal flora is increased, the rate of inflammatory cytologic specimen is also higher than in the control group. The rate of inflammatory smears decreases with the increasing interval of time between insertion and cytological examination. IUD typical changes could be observed only in so far as in this group the cytologic signs of chronic cervicitis were increased. Inflammatory alterations are the reason for the higher rate of "suspicious" smears in the group of IUD-users. There was no higher rate of praecancerous lesions among the IUD users. The importance of these results for the clinical management are pointed out.

IUD insertion following induced abortion.

In a multicenter survey, women who received an IUD immediately after abortion were compared with abortion patients who started using oral contraception. Additionally, women receiving a Nova T were compared with women receiving a Multiload 250. Follow-up data were gathered after 6 weeks. Pain was a common phenomenon post-abortum. In the study group of IUD users, complaints about pain were not more frequent than among controls, but if pain was experienced, it was more intense and of longer duration among IUD users. Bleeding immediately following the induced abortion was less frequent among IUD users, but if bleeding occurred, it tended to last longer. The first menstrual period after the induced abortion was heavier and more painful among IUD users. Expulsion of the IUD occurred in 10 cases (3.3%), all of them with the Nova T, none with Multiload. The study did not generate evidence for an increased risk of PID in women receiving an IUD after an induced abortion.

Endometrial morphological changes in IUD users: a review.

The introduction of an intrauterine device into the uterine cavity induces a foreign body reaction in the surrounding endometrium which is characterized by the infiltration of polymorphonuclear leucocytes and macrophages into the endometrial stroma and subsequently through the surface epithelium. Leucocyte migration is greater with copper IUDs than with inert IUDs. Ulceration of the surface epithelium, haemorrhage of erythrocytes and microthrombosis of stomach capillaries occur in the functional endometrium in contact with inert and copper IUDs. In endometrium adjacent to, but not in contact with, the IUD gaps appear in the endothelial lining of small blood vessels without a haemostatic response. The most striking response in endometrium exposed to progesterone-releasing IUDs is the occurrence of dilated, thin-walled vesicles, associated with a thinning of the surface epithelium and a decidual reaction in the stroma. A uniform suppression of the endometrium in progesterone IUD users is always found after six months of treatment, whereas the insertion of IUDs releasing 20-30 micrograms levonorgestrel induce a profound uniform suppression of the functional endometrium throughout the uterus after only four weeks.

Ovarian function during use of a levonorgestrel-releasing IUD.

Ovarian function was studied for two complete menstrual cycles in 9 regularly menstruating women and for 8 weeks in three amenorrhoeic women who had used levonorgestrel-releasing IUDs (LNG-IUD) for more than four years. Nine patients using copper IUDs (Nova-T) were studied for two complete menstrual cycles as controls. According to progesterone levels, 15/17 cycles in women using LNG-IUDs were ovulatory, whereas only 8/17 cycles showed normal follicular growth and rupture as judged by ultrasound. In ovulatory cycles, the peak progesterone levels were lower than in the controls. The preovulatory estradiol and LH peak levels were also lower than in control subjects. SHBG levels were lower in LNG-IUD users than in copper IUD users. It is concluded that, although the dose of levonorgestrel released from the IUD is very low, it probably exerts an effect on the gonadotrophin secretion, which disturbs follicular development in many of the women studied, which in addition to the local effect on the endometrium, contributes to its high contraceptive efficacy.

Evaluation of 24 patients with IUD-related problems: hysteroscopic findings.

The clinical and diagnostic findings in 24 patients with IUD-related abnormal uterine bleeding or missing IUDs have been evaluated with special reference to hysteroscopy. For the IUD-related abnormal uterine bleeding no gross uterine or tissue pathology has been revealed except for chronic inflammatory reaction of the endometrium. In half of the cases the IUD showed embedment, displacement within the uterine cavity or migration into the uterine wall, which may be a possible cause of the IUD-related abnormal uterine bleeding. For the detection and removal of IUDs with missing strings, partially embedded and perforated IUDs or retained broken parts of it, the hysteroscopic procedure appeared to be invaluable and in our opinion should be the method of choice.

Fifteen years' experience with the Multiload IUD.

The Multiload IUD with an exposed copper surface area of 250 mm2 (MLCu250) was developed in 1972 and has become one of the most widely used IUDs. Modifications to the MLCu250 include an increase in the area of exposed copper wire to 375 mm2 (the MLCu375) and an increase in the diameter of copper wire from 0.3 to 0.4 mm. The Multiload has been evaluated extensively in noncomparative and comparative clinical trials. In these latter studies the MLCu250 performed better than the Cu-7 and TCu-200, and the MLCu375 performed better than the Fincoid or Nova T and about equally as well as the TCu380. Pooled data from over 26,000 insertions of the MLCu250 gave the following 3-year cumulative event rates (per 100 women): pregnancy, 2.0; expulsion, 3.1; removal for pain/bleeding, 7.1. Comparative studies of the Multiload and other IUDs have shown all IUDs in current use are associated with similar rates of pelvic inflammatory disease. IUDs such as the MLCu375 that have larger copper surface areas appear to be associated with lower ectopic pregnancy rates. Follow-up studies of women who have had their Multiloads removed indicate that use of the device does not impair future fertility or affect pregnancy outcome. All IUD users, regardless of the type of IUD used, are at risk of complications. On balance, the benefits of IUD usage far exceed the associated risks.

Fertility after complicated and non-complicated use of IUDs. A controlled prospective study.

From 1980 to 1985, 600 women participated in a prospective study of three copper IUDs. Women who had removed their IUD by April 1985 because of IUD-related complications or planned pregnancy after non-complicated use were examined for return of fertility. Within 39 months after removal, all 97 women who planned pregnancy had conceived. By April 1987, one of the 147 women with a previous IUD complication needed a fertility work-up. Among the remaining 146 women, 72 women had conceived, while 74 women neither had pregnancy plans nor had conceived after IUD removal. Three (1.8%) out of the 169 pregnancies after IUD removal were extrauterine; 17 (10.1%) were spontaneous abortions. One percent of the women planning pregnancy requested induced abortion, compared to 29% among women who removed the IUD due to complications (p less than 0.01). From these data we conclude that use of copper-containing IUDs did not affect subsequent fertility.

Observation of the activity of factor VIII in the endometrium of women pre- and post-insertion of three types of IUDs.

The endometrial materials were obtained from 90 women who had been randomly inserted with three types of IUDs (Stainless steel ring, SS; copper T 220, TCu 220, and levonorgestrel-releasing device, LNG). An immunoperoxidase reaction, PAP method, with the antiserum of Factor VIII as the primary antibody, was carried out to detect the Factor VIII activity in the endometrial endothelium pre- (control) and post-insertion of the IUDs. The results revealed that: 1. There was a generalized lower Factor VIII activity in the endometrium of women post-insertion of IUDs (except LNG). 2. Comparison of the Factor VIII activity in the endometrium of women using different types of IUDs showed that the TCu type and the SS type decreased the activity significantly whereas the activity remained unchanged after 3-6 months' use of the LNG-IUD. The different types of IUDs seemed to influence the coagulation regulatory system in different ways; the lower Factor VIII activity, the more tendency to bleeding. 3. The Factor VIII activity in the endometrium of women using IUDs was lower in all phases of the menstrual cycle including the proliferative phase when the Factor VIII activity is normally high. It cannot be excluded that this could be a contributing factor to IUD-induced bleedings.
