Fertility outcome after ectopic pregnancy and use of an intrauterine device at the time of the index ectopic pregnancy

Fertility after ectopic pregnancy (EP) was investigated in a non-selected population taking into account intrauterine device (IUD) use at the time of the EP. Between January 1992 and June 1996, 647 women listed in the EP register of Auvergne (France) were followed up. The analysis included only the 328 women who were seeking to become pregnant: 23 women using IUD at the time of the index EP (IUD users) and 305 IUD non-users. Among IUD users, there was no recurrence of EP, and the 1 year cumulative rate was 87% [95% confidence interval (CI): 73-100%] for intrauterine pregnancies and 86% (95% CI: 72-100%) for deliveries. Among IUD non-users, the 2 year cumulative rate for recurrence of EP was 28% (95% CI: 17-39%), and the 1 year cumulative rates were 60% (95% CI: 53-66%) for intrauterine pregnancies and 44% (95% CI: 38-56%) for deliveries. The adjusted intrauterine pregnancy rate of IUD users was not significantly different from that of IUD non-users. However, IUD non-users had more miscarriages, so their delivery rate was lower.     

Serum vascular endothelial growth factor as a possible marker for early ectopic pregnancy

BACKGROUND: This study evaluated serum vascular endothelial growth factor (VEGF) concentrations in women with normal intrauterine pregnancy (IUP), arrested IUP and ectopic pregnancy (EP). METHOD: This was a prospective, case-control study evaluating serum VEGF concentrations among 45 early pregnant women who subsequently were found to have an EP, a normal IUP or an arrested IUP (15 women in each group). Patients were stratified according to serum VEGF concentrations above and below 200 pg/ml. RESULTS: There was a significant difference in VEGF concentrations among women with EP, arrested IUP and normal IUP (306.1 +/- 26.5, 169.7 +/- 16.6 and 27.0 +/- 4.4 pg/ml respectively, P < 0.001). With a cut-off concentration of 200 pg/ml, serum VEGF could distinguish normal IUP from EP with a sensitivity of 88%, a specificity of 100% and a positive predictive value of 100%. Between EP and arrested IUP, the sensitivity was 87.5%, specificity 75% and positive predictive value of 77.8%. CONCLUSIONS: VEGF is a potential marker for EP. Its concentrations in women with EP are higher than in those with normal and arrested IUP.     

Salpingectomy - the laparoscopic surgical choice for ectopic pregnancy

The aim of this study was to assess the fertility outcome afterectopic pregnancy (EP) treated by laparoscopic salpingectomy.Among the 375 patients who underwent this operation betweenJanuary 1983 and December 1993, there were 145 patients whodesired pregnancy and whose contralateral tube was not obstructed.The overall rate of intrauterine pregnancy (IUP) was 50.3%,with an EP rate of 15.2%, These results were analysed accordingto the patients‘ past history together with the conditionof the contralateral tube at the time of the laparoscopy. Wedefined two groups. Group 1 included patients who had no previoushistory of tubal surgery and whose contralateral tube was normal.Group 2 comprised those patients who had a previous historyof tubal surgery and/or those whose tube was pathological, butnot obstructed. Postoperative fertility of the patients in group1 was significantly higher than that of the patients in group2, with IUP rates of 75 and 36.6% respectively (P < 0.001),and a risk of EP recurrence of 9.6 and 183% respectively. Ingroup 1, the actuarial IUP rate at 24 months was significantlyhigher than that for the patients in group 2 (66.7 versus 36.9%;P < 0.001). The patient’s past history and the conditionof the contralateral tube were the two major factors relatedto fertility outcome after laparoscopic salpingectomy for EP.In patients with no past history of tubal surgery or infertilityand whose contralateral tube was normal, the fertility resultsafter laparoscopic salpingectomy appeared comparable to thoseobserved after conservative laparoscopic treatment     

The occurrence and outcome of 39 pregnancies after 1621 cases of transcervical resection of endometrium

BACKGROUND: To evaluate the outcomes and management of pregnancy after transcervical resection of the endometrium (TCRE). METHODS: Retrospective study of 39 pregnancies after 1621 procedures of TCRE. RESULTS: Among 1621 women who were successfully followed up after TCRE, there were 39 pregnancies in 32 women, including five ectopic pregnancies (12.8%) and 34 intrauterine pregnancies (87.2%). The majority of pregnancies (84.6%) occurred within the first 2 years. In the first year after TCRE, the incidence of pregnancy was 1.5%. In women who had amenorrhoea after TCRE, the chances of conception (2/676; 0.3%) were significantly (P < 0.001) lower than for those who continued to have period (30/945; 3.2%). Thirty-two cases with intrauterine pregnancy were terminated under ultrasound guidance with two difficult procedures. Only one pregnancy in our study resulted in spontaneous miscarriage which was managed by suction curettage. One term pregnancy had placenta increta resulting in Caesarean hysterectomy. CONCLUSIONS: Pregnancies after TCRE are associated with increased risk, and clinicians should be aware of the various complications of pregnancy that may occur after TCRE, including an increased risk of ectopic pregnancy. Surgical termination of pregnancy after TCRE is potentially a difficult procedure and should be carried out under ultrasound guidance.     

Fertility after ectopic pregnancy: first results of a population-based cohort study in France

The purpose of this paper was to evaluate the reproductive outcomeafter ectopic pregnancy (EP) from a population-based registerin the centre of France. Since 1992, all the women aged 15–44years, who permanently reside in the target area and who weretreated either by surgical or medical procedures for an ectopicpregnancy in one of the area centres, have been registered andprospectively followed until 45 years of age. The analysis presentedwas based on the 155 women registered between January 1992 andMarch 1994 who were followed up for at least 6 months, and whowere seeking a new pregnancy. The mean follow-up period was16 months. A total of 102 women (66%) obtained a pregnancy.The first conception was intrauterine for 92 women, and 10 hada recurrence of ectopic pregnancy. Risk factors of recurrencewere prior spontaneous abortion and prior tubal damage. Forthose women who conceived, the mean time to obtain pregnancy(’time to pregnancy‘) was 4.8 months. The 1 yearcumulative intrauterine pregnancy rate (i.e. the probabilityof obtaining an intrauterine pregnancy within 1 year of seekingpregnancy) was 70%. After multivariate analysis by a Cox regression,the factors associated with higher fertility were age < 30years, high educational level and no prior tubal damage.     

Is previous aberrant reproductive outcome predictive of subsequently reduced fecundity?

BACKGROUND: Effect of past reproductive performance on subsequent fecundity is uncertain. METHODS: A total of 2983 consecutive pregnant women self-completed questionnaires about time to pregnancy (TTP), pregnancy planning, previous pregnancies, contraceptive use, age, and individual/lifestyle variables. Outcome measures were: TTP, conception rates (CR) and, subfecundity odds ratio (OR; with 95% confidence intervals) before and after each outcome of last pregnancy. RESULTS: After miscarriage, TTP was longer than before miscarriage [2.1 (1.4-3.0), P < 0.001] and than TTP after livebirth [OR = 2.1 (1.6-2.6), P < 0.001]. Also subfecundity OR after miscarriage increased [1.7 (1.2-2.4), 1.8 (1.2-2.5), P = 0.001, 0.002 respectively]. This effect was more evident in older and obese women. Compared with livebirth, time to ectopic pregnancy (EP) was longer [OR = 13.8 (1.8-108.5), P = 0.001] but TTP after EP was not significantly different. Subfecundity OR relative to livebirth were 12.8 (3.6-45.0) (P<0.001) before, and 3.9 (1.4-11.0) (P=0.01) after, EP. The CR after EP increased 3-fold (1.1-8.3) over those prior to EP. Time to the terminated pregnancies even without contraceptive failures was shorter than that to livebirth [OR = 0.5 (0.3-0.7), P = 0.001] and than TTP after termination [0.35 (0.1-0.8), P = 0.001]. Also subfecundity OR increased after termination [7.2 (1.8-29.7), P = 0.02]. CONCLUSIONS: Miscarriers should be counselled about short-term reduction in subsequent fecundity, and earlier investigations should be considered in those who have other potential risk factors for reduced fertility. Further studies are required to clarify the relatively favourable effect on fecundity following EP and the relative reduction in fecundity after termination of pregnancy.     

The accuracy of transvaginal ultrasonography for the diagnosis of ectopic pregnancy prior to surgery

BACKGROUND: To evaluate the accuracy of transvaginal ultrasonography (TVS) for the detection of ectopic pregnancies (EPs) in women undergoing surgery for presumed ectopic pregnancy. METHODS: A prospective, observational study. Women were diagnosed with an EP using TVS if any of the following were noted in the adnexal region: (i) an inhomogeneous mass or blob sign adjacent to the ovary and moving separately from the ovary; or (ii) a mass with a hyper-echoic ring around the gestational sac or bagel sign; or (iii) a gestational sac with a fetal pole with or without cardiac activity. The final diagnosis was based on the findings at surgery and subsequent histology of removed tissues. RESULTS: 6621 consecutive women underwent TVS during the study; 200/6621 (3.0%) women were diagnosed as having an EP using TVS. Forty-eight non-surgically managed women were excluded from the analysis. 85.5% of women presented with symptoms and 14.5% were asymptomatic. In 88 (57.9%) cases an inhomogeneous mass or blob sign was visualized and in 20 cases (13.2%) an embryo +/- cardiac activity. Thirty-one (20.4%) had a hyper-echoic ring in the adnexa. In 11 (7.2%) cases there was no evidence of either an intra-uterine (IUP) or EP on ultrasound. Two (1.3%) IUPs were subsequently diagnosed as heterotopic pregnancies. There was no association between the presenting complaints and TVS findings. 152 surgical procedures were performed. In 5.9% (9/152) of these cases no EPs were confirmed in fallopian tube or pelvis at laparoscopy. In 9.1% (13/143) of cases an EP was visualized at surgery when not seen on the index ultrasound scan. The sensitivity and specificity of TVS to detect EP were 90.9% and 99.9%, respectively, with positive and negative predictive values of 93.5% and 99.8%, respectively. CONCLUSIONS: 90.9% of ectopic pregnancies in this study population can be accurately diagnosed using TVS prior to surgery. The diagnosis of an ectopic pregnancy should be based on the positive visualization of an adnexal mass using TVS. This should in turn result in a decrease in the number of false positive laparoscopies.     

Vascular endothelial growth factor (VEGF) and discrimination between abnormal intrauterine and ectopic pregnancy

BACKGROUND: This study evaluated serum vascular endothelial growth factor (VEGF) levels in women with abnormal intrauterine and ectopic pregnancies (EP) at 6 weeks gestation. METHODS: We conducted a prospective case-control study comparing serum VEGF concentrations among 84 women with abnormal intrauterine and EP matched for gestational age (42 women in each group). We analysed whether serum VEGF levels >200 pg/ml would discriminate between abnormal intrauterine pregnancies and EP at 6 weeks gestation, and we calculated sensitivity, specificity and positive predictive values. RESULTS: Serum VEGF concentrations did not show statistically significant differences between women with abnormal intrauterine pregnancies (median, 198.5 pg/ml; range, 0-701.6) and EP (median, 211.2 pg/ml; range 0-628.8). When threshold concentrations of a serum VEGF level >200 pg/ml were used, abnormal intrauterine pregnancy could be distinguished from EP with a sensitivity of 56%, a specificity of 51%, and a positive predictive value of 53%. CONCLUSIONS: VEGF does not discriminate ectopic from abnormal intrauterine pregnancies at 6 weeks gestation, and thus should not be used in clinical management.     

Aberrant cytokine production by peripheral blood mononuclear cells in recurrent pregnancy loss?

BACKGROUND: Successful pregnancy may depend on a Th2-type cytokine response, whilst, conversely, a poor pregnancy outcome may be associated with an increase in Th1 cytokines and a concomitant decrease in Th2 cytokines. This prospective study was designed to elucidate whether a failure of the cytokine shift pre-dated miscarriage and was therefore likely to be an aetiological factor in recurrent pregnancy loss (RPL). METHODS: Cytokine production by stimulated peripheral blood mononuclear cells from 46 pregnant women who had previously suffered idiopathic RPL during early pregnancy was compared with 25 gestationally age-matched pregnant controls and 11 non-pregnant women. RESULTS: Production of IFN-gamma was lower in pregnant than in non-pregnant women and even lower in RPL pregnant women (P = 0.0191). IL-10 was increased in pregnant women compared with non-pregnant controls, and further increased in RPL patients (P = 0.026). IL-4 was also increased in women with RPL (P = 0.0001). No differences in IFN-gamma, IL-10 or IL-4 secretion were observed in RPL patients who subsequently miscarried compared with those who successfully completed the pregnancy. RPL women with a successful reproductive outcome had similar concentrations of TNF-alpha to pregnant women, RPL women who subsequently miscarried had significantly lower levels than either pregnant women (P = 0.02) or non-pregnant controls (P = 0.0004). CONCLUSIONS: Contrary to our hypothesis, the cytokine shift, which appears to characterize normal pregnancy, was accentuated rather than diminished in RPL pregnant women.     

Successful myomectomy during pregnancy

BACKGROUND: Although leiomyomas usually remain asymptomatic during pregnancy, they may complicate its course. In this study, pregnancy outcome observed when myomectomy was performed during pregnancy in carefully selected patients is presented. METHODS: A prospective cohort study of 13 women who underwent myomectomy during pregnancy between January 1994 and December 2001. Surgical management of leiomyoma was required on the basis of characteristics of the myoma and symptoms. RESULTS: Among a total of 15,579 women registered at the authors' prenatal clinic, 622 consecutive pregnant women had sonographically identified myoma; hence, the incidence was 3.9% (95% CI 3.6-4.3%). The vast majority of these women was asymptomatic during pregnancy or managed conservatively (97.4%; 95% CI 96-98%). Among 622 pregnant patients with leiomyoma, 13 presented with complications during pregnancy that required surgical intervention (2.1%; 95% CI 0.9-3.2%), due to increase in lesion size causing discomfort and/or severe abdominal pain not responding to conservative management with analgesic and non-steroidal anti-inflammatory drug medication. In 92% of these cases, successful myomectomy was performed and the pregnancy progressed to term without further complications. CONCLUSIONS: These data provide reassurance for pregnant women with uterine myoma. Surgical management of uterine leiomyoma during pregnancy may be successfully performed in carefully selected patients.     

Diagnostic value of the plasmatic ADM level for early ectopic pregnancy

Objective: To analyze the plasmatic ADM level in early pregnancy and to investigate the diagnostic value of ADM in early ectopic pregnancy (EP). Methods: 70 patients with EP who had menopause for 5~8 weeks were included as study group, while 155 women with normal intrauterine pregnancy were also included as control group. The correlation between ADM level and menopause weeks was statistically analyzed and ROC curve was used to identify the diagnostic value of ADM. Results: (1) In 155 cases of normal intrauterine pregnancy, the plasmatic ADM level was increased with menopause weeks in linear relationship, and the correlation coefficient (R) was 0.991 (P<0.05). In 70 patients with EP, no significant increase was found with menopause weeks and no linear relationship can be found between ADM level and menopause weeks in EP group. The correlation coefficient (R) was 0.744 (P>0.05). (2) The multiple of median of plasmatic ADM level in EP group of menopause for 8 weeks was obviously lower than the intrauterine control group (P<0.01). (3) ROC curve was used to analyze the cut-off value of ADM level in the diagnosis of EP, and the area under the ROC curve was 0.523 (P>0.05) regardless of menopause weeks, however, the area under the ROC curve was 0.702 (P<0.05) at 8 weeks after menopause with sensitivity of 53.50% and specificity of 85.00%. Conclusions: Different from normal intrauterine pregnancy, plasmatic ADM level in early EP was relatively lower and no significant increase was found with menopause weeks; further studies are still needed for plasmatic ADM level as an indicator in the early diagnosis of EP.     

Defective endovascular trophoblast invasion in primary antiphospholipid antibody syndrome-associated early pregnancy failure

BACKGROUND: Primary antiphospholipid antibody syndrome (PAPS) is an established cause of recurrent pregnancy loss, traditionally presumed to be due to 'intraplacental thromboses'. This study examines products of conception (POC) from early pregnancy failures to investigate the mechanism of pregnancy loss. METHODS: POC from patients attending a recurrent miscarriage clinic and from terminations of pregnancy for non-medical reasons were examined histologically with particular regard to the presence or absence of vascular or intervillous thromboses and decidual endovascular trophoblast invasion. RESULTS: There were 31 PAPS-positive, 50 PAPS-negative, 34 aneuploid and 20 control cases at 6-14 weeks gestation. Villous morphology and frequency of intervillous thrombosis were not different among groups. Normal intradecidual endovascular trophoblast invasion was identified significantly less frequently in PAPS+ cases (24%), compared with controls (75%), aneuploid (53%), or PAPS- cases (61%; Z = -3.0, P < 0.01). In all cases there was apparently normal interstitial extravillous trophoblast invasion. CONCLUSIONS: Defective decidual endovascular trophoblast invasion, rather than excessive intervillous thrombosis, is the most frequent histological abnormality in PAPS+ associated early pregnancy loss. Furthermore, endovascular trophoblast invasion is not significantly reduced in the majority of fetal aneuploidy-associated pregnancy failures.     

Random urinary pregnanediol glucuronide measurements in pregnancy: lack of utility for evaluation of first-trimester vaginal bleeding

Progesterone and its urinary metabolite pregnanediol-3 alpha-glucuronide (PDG) are generally lower in women with abnormal pregnancies compared to those with normal intrauterine gestations. We evaluated the ability of random urinary PDG measurements determined by enzyme immunoassay (EIA) to differentiate normal from abnormal pregnancies. Patients with first-trimester vaginal bleeding (n = 104) were evaluated. Eventual outcomes indicated 39 women had viable intrauterine pregnancies (IUPs), 54 had spontaneous abortions (SABs) and 11 had ectopic pregnancies (EPs). Urinary PDG was significantly lower in SAB and EP compared to IUP patients. However, a wide range of values in IUP patients was noted (3.2-93.3 micrograms/ml), due to varying degrees of patient hydration at presentation. Hence, random measures of urinary PDG demonstrated poor specificity (32.8%) in correctly differentiating normal from abnormal gestations, thus limiting its clinical usefulness.     

Laparoscopic myomectomy in premenopausal women with and without preoperative treatment using gonadotrophin-releasing hormone analogues.

The present study was undertaken in order to evaluate the usefulness or otherwise of preoperative gonadotrophin-releasing hormone (GnRH) analogue treatment prior to laparoscopic myomectomy. From June 1993 through December 1996, 60 premenopausal women aged between 25 and 42 years and with a sonographic diagnosis of intramural or subserous myomas were selected for laparoscopic myomectomy at the Department of Obstetrics and Gynaecology of the Catholic University of The Sacred Heart, Rome. According to a computer-generated sequence, 30 patients were submitted to three cycles of GnRH analogue treatment prior to surgery, whereas no preoperative treatment was prescribed to the other 30 patients. Laparoscopic myomectomy was successfully performed in all patients for a total of 174 myomas excised laparoscopically. The patients' mean age, the number of myomas per patient, the mean diameter of the myomas, parity and estimated blood loss were similar in both groups. The operative time was significantly longer in the group of patients submitted to GnRH analogue treatment than that of the group of patients not submitted to any preoperative medical therapy (157.5 +/- 74.71 versus 112.33 +/- 54.71 min; P = 0.01). No intra-operative complications occurred. In no case was blood transfusion necessary. Two patients developed post-operative fever (temperature > 38 degrees C.). The mean length of hospital stay was 2.39 days and was similar in both groups. Thirteen spontaneous pregnancies occurred among 24 infertile patients (54.1%). The pregnancy rate for these patients was similar in both groups. The viable term delivery rate was 45.8%. The authors conclude that laparoscopic myomectomy is a feasible and safe procedure. The post-operative pregnancy rate for infertile patients is similar to that following laparotomic myomectomy. The present study suggests that preoperative GnRH analogue treatment does not offer any significant advantages for laparoscopic myomectomy.     

Pregnancy: The expectant management of early pregnancies of uncertain site

The role of expectant management was evaluated in 80 women inwhom clinical examination, including vaginal ultrasound, hadfailed to identify the location of an early pregnancy. In 45cases, spontaneous resolution of the pregnancy products occurred.A normal intra-uterine pregnancy was diagnosed in 12 patients.A total of 23 patients underwent active therapeutic measuresdue to an ectopic pregnancy (n = 16) or a spontaneous abortion(n = 7). The effectiveness of different diagnostic measuresto identify patients suitable for expectant management was analysed.In 33/34 patients (97%) with a relative daily human chorionicgonadotrophin (HCG) change of <–5%, and a serum progesteroneconcentration of <20 nmol/l, spontaneous resolution of thepregnancy products occurred. Among 46 cases, with a relativedaily HCG change of >–5% and/or serum progesterone>20 nmol/l, active therapeutic measures were carried outin 22 cases (48%), a normal intra-uterine pregnancy was diagnosedin 12 cases (26%) and spontaneous resolution of the pregnancyproducts occurred in 12 cases (26%). In conclusion, the combinationof a single progesterone assay and serial HCG determinationsretrospectively identified early pregnancies of uncertain locationin whom expectant management was a safe management option.     

Fertility and pregnancy outcomes in men and women with cystic fibrosis in the United Kingdom

BACKGROUND: The survival of patients with cystic fibrosis (CF) now occurs into the fourth decade of life. Our aim was to evaluate the fertility and pregnancy outcomes of men and women with cystic fibrosis within a large British cohort. METHODS: A population based cohort study of 4659 males and females registered with the UK Cystic Fibrosis Database in 2001. RESULTS: Poor respiratory health (forced expiratory volume in 1 s FEV1 <50%) and CF-related diabetes increased significantly post-puberty compared with childhood. Few individuals with CF sought fertility treatment (1% men, 0.5% women) or achieved pregnancies (1.3% of partners of men, 5.7% women). However, the majority of pregnancies had a good outcome (67% live term birth among male partners, 74% among women). Women who achieved a pregnancy were less likely to suffer from poor respiratory health (FEV1 <50%), age adjusted Odds Ratio 0.6 (95% CI 0.3-0.9), less likely to be homozygous for the DF508 genotype OR 0.5 (95% CI 0.3-0.9) and had a significantly earlier median age at diagnosis (0 years vs 2 years, P=0.001). CONCLUSIONS: Increasing numbers of males and females with cystic fibrosis are reaching reproductive age but currently very few have a child. Optimal adult health should improve the reproductive prognosis for both men and women.     

Is previous use of hormonal contraception associated with a detrimental effect on subsequent fecundity?

BACKGROUND: The effects of contraception on subsequent fecundity are yet to be substantiated. METHODS: A total of 2841 consecutive pregnant women in Hull and Sheffield completed questionnaires inquiring about time to pregnancy (TTP), contraceptive use, pregnancy planning, previous pregnancies, age and lifestyle characteristics of each partner. Outcome measures were mean TTP, conception probability and odds of subfecundity after discontinuing each contraceptive method. RESULTS: TTP following long-term combined oral contraceptive (COC), short-term intrauterine device (IUD) or any duration of injectable use were 2.0-, 1.6-, 3.0-fold longer than TTP after condom use, respectively. Within 6 months of discontinuing COC or injectable use, conception probabilities were 0.86 and 0.34, respectively, whereas those relevant to other methods were not significantly different. All levonorgestrel intrauterine system (IUS) users conceived within 1 month. Relative to condoms, odds of subfecundity after COC, injectable and short-term IUD use were 1.9, 5.5, 2.9, respectively. The effect of COC and injectables was stronger with long-term use, in older, obese or oligomenorrhoeic women. Similar results were obtained after adjustment for potential confounders. CONCLUSIONS: A significant reduction in fecundity occurs after COC, IUD or injectables, which is dependent on the duration of use. The effect of COC and injectables is evident in women with a potentially compromised ovarian function. Use of progesterone-only pills or IUS is not associated with a significant effect.     

Are pregnancy-associated plasma protein-A (PAPP-A) and CA 125 measurements after IVF-ET possible predictors of early pregnancy wastage?

Pregnancy-associated plasma protein-A (PAPP-A), a macromolecular glycoprotein of placental origin, was reported to be depressed in established ectopic pregnancies. CA 125 is a known marker for ovarian cancer found to be elevated during the first trimester of pregnancy and in women with pelvic inflammatory disease. The present study investigated the usefulness of these parameters to predict the outcome of pregnancy in asymptomatic patients with a positive pregnancy test after in-vitro fertilization and embryo transfer (IVF-ET). Blood samples (n = 159) were obtained at different periods of time post-ET from 39 women, 21 of whom experienced a normal pregnancy, 12 had an intrauterine abortion and six had an ectopic pregnancy. PAPP-A and CA 125 were measured by radioimmunoassays. From day 30 onwards in normal pregnancies, PAPP-A was significantly increased over non-pregnant controls. In the spontaneous abortion group, the levels of PAPP-A were significantly lower than in normal pregnancy but higher than in non-pregnant controls. In ectopic pregnancy, PAPP-A remained at the level of non-pregnant controls throughout the entire observation period. CA 125 was significantly increased in all types of pregnancy. However, in two cases of hyperstimulation followed by a normal pregnancy and in four cases of ectopic pregnancy with signs of peritoneal irritation (hydrosalpinx, ruptured ectopic or salpingitis) the levels of CA 125 were 15-50 times higher than in normal pregnancies.(ABSTRACT TRUNCATED AT 250 WORDS)     

Pregnancy-associated plasma protein A in pregnancy-related gynaecologic emergency

Serum concentrations of pregnancy-associated plasma protein A (PAPP-A) were measured in patients with pregnancy-related gynaecologic emergencies including ectopic pregnancy (n = 124) and intrauterine abortion (n = 40). The results were compared with those in normal pregnancy (n = 136) and non-pregnant women (n = 460). In ectopic pregnancy and intrauterine abortion, the PAPP-A levels were lower than in normal pregnancy. In patients with a pregnancy-related gynaecologic emergency PAPP-A was undetectable in 82% of the ectopic pregnancies and in 55% of the intrauterine abortions. Considering the frequency of ectopic pregnancy (35.8%) and intrauterine abortion (52.3%) among all patients with pregnancy-related disorders, the likelihood that a pregnant patient with undectable PAPP-A has an ectopic pregnancy is 30%, and intrauterine abortion is 29%. These results indicate that although PAPP-A levels in ectopic pregnancy and intrauterine abortion are lower than in normal pregnancy, PAPP-A measurement cannot be used to distinguish between ectopic pregnancy and intrauterine abortion.
