Serological responses of patients with ectopic pregnancy to epitopes of the Chlamydia trachomatis 60 kDa heat shock protein

Clinical and histopathological correlations of immunoreactivity to Chlamydia trachomatis and to epitopes of the C. trachomatis 60 kDa heat shock protein (hsp60) among women with ectopic pregnancy were evaluated in a case-control study. Serological responses to 13 synthetic peptides corresponding to major epitopes of the chlamydial hsp60 were determined in 67 women treated for ectopic pregnancy and 45 women with uncomplicated pregnancy in utero. Plasma cell salpingitis was detected in 29 (43.3%) of the ectopic patients. Its presence correlated with antibodies to two hsp60 epitopes, encompassing amino acids 260-271 and 411-422 (P = 0.02). Antibodies to these two epitopes, along with five other epitopes, also correlated with peritubal adhesion formation in ectopic pregnant patients (P < 0.01). Antibodies to epitopes 260-271 and 188-199 also correlated with a history of pelvic inflammatory disease (PID; P = 0.05). Patients with ectopic pregnancy were also more likely than their intrauterine pregnant controls to have present anti-chlamydial immunoglobulin G (P < 0.005). Women positive for both C. trachomatis and hsp60 epitope antibodies had an increased prevalence over controls of salpingitis, pelvic adhesions or history of PID (P < 0.05). In contrast, patients who were positive for only C. trachomatis antibodies or only hsp60 epitope antibodies did not differ from antibody-negative patients in each of these categories.     

Chlamydial genital infections and laparoscopic findings in infertile women

Several studies have shown that previous chlamydial genital infection, reflected by serological markers, is strongly associated with tubal damage leading to tubal infertility. In 105 women undergoing laparoscopy, multiple samples were collected from the lower (urethra and cervix) and upper (endometrium, peritoneal fluid, tubal lumen) genital tract, in order to isolate Chlamydia trachomatis in cell culture. Chlamydia trachomatis was isolated from at least one site in 13 (30.9%) of 42 infertile women with tubal infertility, in 5 (12.1%) of 41 women with unexplained infertility, in 1 of 4 women affected by acute salpingitis and in 1 (5.5%) of 18 women with endometriosis or uterine malformations. The latter group was the control group. Thirteen (65%) of the 20 positive women harboured Chlamydia trachomatis in their upper genital tract alone and 16 women were positive in one or both tubes. Only one of the positive women showed laparoscopic signs of acute pelvic infection. Four of the 5 positive women with unexplained infertility harboured Chlamydia trachomatis in the tubal lumen. This study confirms that chlamydial infection is strongly associated with tubal damage. It suggests that cervical cultures are inadequate for excluding a tubal infection and that chlamydial colonization of the tubal mucosa is possible in the absence of symptoms and laparoscopic signs of active infection.     

Laparoscopic fimbrioplasty: an evaluation of 35 cases

The aim of this prospective study was to assess the value of laparoscopic treatment of severe fimbrial occlusions. During a period of 52 months infertile patients with fimbrial lesions were treated by operative laparoscopy. Only those patients requiring incision of the tubal serosa (salpingostomy) were included, representing the most severe lesions. The most frequent cases, those patients requiring simple adhesiolysis and deagglutination of the fringes, were excluded. All tubal lesions were documented carefully. Positive Chlamydia trachomatis (CT) serology was found in 65.7% of the patients. All the patients were followed up for at least 2 years. Three patients lost to follow-up were defined as failures. The global conception rate was 74.3%. The intrauterine pregnancy rate was 51.4%, and the 'take home baby rate' was 37.1% (only the first pregnancy being taken into account). The ectopic pregnancy rate was 22.9%. A positive CT serology was found to have a significant influence on the outcome. It can be concluded that the laparoscopic approach provides results similar to those obtained by microsurgery for the treatment of severe fimbrial occlusions, and represents an acceptable alternative to in-vitro fertilization (IVF) in selected cases.     

Ectopic bone formation in a child with a head injury: complete regression after immobilisation

OBJECTIVE: To study the correlation between microsurgical tubal reversal after tubal sterilization and ectopic pregnancy. METHODS: 1029 women who underwent microsurgical tubal reversal were followed up. The causes of ectopic pregnancy were analysed and discussed. RESULTS: 960 intrauterine pregnanciess and 12 ectopic pregnancies occurred. The 12 ectopic pregnancies were all tubal ones, among which 2 had intrauterine pregnancies. The rate of ectopic pregnancy in the 1029 women was 1.17%, and in the pregnant cases was 1.23%. The ratio of intrauterine pregnancy to ectopic pregnancy was 1:80. The rates of ectopic pregnancy in the 1st, 2nd year and 2 years later after tubal reversal were not significantly different respectively among the tubal reversal and among the pregnant cases. The rates of ectopic pregnancy in the 1st and 2nd 6 months after tubal reversal were not statistically different. The early tubal hydrapertubation could only increase the chance of ectopic pregnancy. The sterilization method, reversal mode, and interval between sterilization and reversal were not related to the ectopic pegnancy. CONCLUSION: When the lesion in the sterilized position is completely removed, the sutures being through the tubal mucosa and the early tubal hydrapertubation not carried out, the chance of ectopic pregnancy can not be increased after tubal reversal. The contraception 6 months after tubal reversal is not related to ectopic pregnancy.     

Chlamydia trachomatis, pelvic inflammatory diseases and sterility

The authors analyse the results of direct (cervical, urethral, tubal) and serological research of Chlamydia trachomatis in a sample population of 420 women undergoing celioscopy due to sterility and pelvic pain, paying particular attention to a group of 193 who were found to be suffering from PID (acute, sequelae). In terms of absolute numbers the correlation between chlamydial contact-PID-sterility is confirmed, whereas in an analysis of the levels of direct positivity it is only significant for acute PID, and in cases of sequelae and in sterility with chronic infection with or without tubal damage the direct identification of Chlamydia trachomatis does not differ much from controls. Salpingo-peritoneal isolation was found to be completely lacking in significance.     

Anthropometric, strength, endurance and flexibility characteristics of elite and recreational climbers

Chlamydia trachomatis is a primary cause of acute or silent salpingitis leading to infertility and ectopic pregnancy. The C. trachomatis epidemic, undiscovered in most cases, spreads, mostly in adolescents, during the years following the onset of sexual activity. As opposed to gonococcal infection which has greatly decreased, C. trachomatis cervical and urethral infection is common in young occidentals. More then 30 different studies covering 200-12,000 subjects screened in family planning centers, college women and men, students and military recruits in different parts of the USA, in Scandinavian countries and France, indicate a prevalence of 5-20% (mean 10%) in apparently healthy young females < 25 years and 5-10% in males. Female prevalence is strongly related to age, being highest (15-20%) in women < 20 years old. Several cost-benefit analyses show that the total cost of the general screening in young populations, which can easily be carried out for women in family planning centers, could save twice the cost of treatment for pelvic inflammatory disease caused by C. trachomatis and six times the total cost of C. trachomatis epidemics if late sequelae are taken into account (tubal infertility treatment, ectopic pregnancy). There is a debate among authors concerning the relative merits of total screening versus selective screening in family planning centers, the most common opinion being to do a total screening of women < 20 years old and selective screening of women 20-30 years of age with at least one risk factor, the most common risk factors being more than one partner in a year, purulent, cervical discharge, failure to use condoms and use of a contraceptive pill. Although the data clearly show that C. trachomatis screening is cost-effective, conducting of the diagnostic laboratory tests used in such screening programs should be carefully evaluated relative to cost, feasibility, specificity and sensitivity and should be adapted to the presumed prevalence in screened populations.     

Chlamydial serologic studies and recurrent spontaneous abortion

OBJECTIVE: Our purpose was to investigate the putative association between immunoglobulin G antibodies to Chlamydia trachomatis and recurrent spontaneous abortions. STUDY DESIGN: Sera from 106 idiopathic recurrent aborters and 81 of their partners were tested for immunoglobulin G antichlamydial antibodies by whole inclusion immunofluorescence and compared with 3890 sera from a general antenatal population. Positive sera were further investigated by microimmunofluorescence to determine species (Chlamydia trachomatis, Chlamydia pneumoniae, Chlamydia psittaci) specificity. RESULTS: Twenty-six (24.5%) of women with recurrent spontaneous abortions had immunoglobulin G antichlamydial antibodies compared with 28 (34.6%) of their partners (chi 2 2.25, p < 0.05) and 788 (20.3%) of the general antenatal population (chi 2 1.16, p < 0.05), and the incidence of antibody positivity showed no trend with increasing number of previous abortions. Fourteen women with recurrent spontaneous abortions had antibodies to Chlamydia trachomatis, 12 to Chlamydia pneumoniae. The prevalence of antibodies to C. trachomatis did not differ significantly between women with recurrent spontaneous abortions and their partners, but the male partners had a significantly (p = 0.005) higher prevalence of Chlamydia pneumoniae antibodies. Chlamydial antibody seropositivity did not correlate with subfertility or subsequent pregnancy outcome. CONCLUSION: There is no association between immunoglobulin G antibodies to Chlamydia trachomatis and recurrent spontaneous abortion.     

The risk of ectopic pregnancy after tubal sterilization. U.S. Collaborative Review of Sterilization Working Group

BACKGROUND: Tubal sterilization is an increasingly common method of contraception in the United States. Although pregnancy after sterilization is uncommon, it can occur and may be ectopic. We used data from the U.S. Collaborative Review of Sterilization to estimate the risk of ectopic pregnancy in women who had undergone the common types of tubal sterilization. METHODS: A total of 10,685 women undergoing tubal sterilization were followed in a multicenter, prospective cohort study. We intended to follow all the women for 5 years by means of annual telephone interviews; for women enrolled early in the study, we attempted an additional follow-up telephone interview 8 to 14 years after sterilization. To assess the risk of ectopic pregnancy in these women, we used cumulative life-table probabilities and proportional-hazards analysis. RESULTS: There were 47 ectopic pregnancies in the 10,685 women; the 10-year cumulative probability of ectopic pregnancy for all methods of tubal sterilization combined was 7.3 per 1000 procedures. The cumulative probability varied substantially according to the method of sterilization and the woman's age at the time of sterilization. Women sterilized by bipolar tubal coagulation before the age of 30 years had a probability of ectopic pregnancy that was 27 times as high as that among women of similar age who underwent postpartum partial salpingectomy (31.9 vs. 1.2 ectopic pregnancies per 1000 procedures). The annual rate of ectopic pregnancy for all methods combined in the 4th through 10th years after sterilization was no lower than that in the first 3 years. CONCLUSIONS: A history of tubal sterilization does not rule out the possibility of ectopic pregnancy, even many years after the procedure.     

High prevalence of sexually transmitted diseases in women with urinary infections

OBJECTIVE: To determine the prevalence and factors associated with unrecognized sexually transmitted diseases (STDs) in women who had pelvic examinations and were subsequently released from the ED with a sole diagnosis of urinary tract infection (UTI). METHODS: A 3-month retrospective chart review was performed in an urban teaching hospital ED (> 70,000 visits/year). Women aged 12-45 years who had pelvic examinations and were released from the ED with a sole diagnosis of UTI were included. Patient complaints, physical findings, and laboratory results were reviewed. Laboratory evaluations included the complete blood count, urinalysis, urine pregnancy test, and cervical cultures for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas. RESULTS: Of the 94 women who met study criteria, 53% had proven STDs (19% N. gonorrhoeae, 22% C. trachomatis, 33% Trichomonas). There was no difference between the patients with positive and negative tests for STDs with regard to complaints, physical findings, and laboratory results (all p > 0.05). CONCLUSIONS: Women undergoing pelvic examinations who are subsequently released from this urban ED with the diagnosis of UTI have a high (> 50%) prevalence of occult STDs. No complaint, physical finding, or laboratory result reviewed was associated with the risk of an STD. Consideration should be given to empirical antibiotic therapy in similar urban populations.     

Detection of Chlamydia trachomatis antibodies by 2 novel tests: rELISA and peptide EIA

The performance of 2 newly developed enzyme immunoassays (EIAs) intended for the routine serological diagnosis of chlamydial infections was evaluated. rELISA is based on a recombinant lipopolysaccharide antigen which detects chlamydia genus-specific antibodies, and Chlamydia trachomatis EIA is based on a peptide derived from major outer membrane protein and is therefore species-specific. Both tests distinguished patients with tubal factor infertility (TFI) or pelvic inflammatory disease (PID) from the controls. The prevalence of IgA antibodies was higher for the PID patients than for the TFI patients; the finding indicates a more active state of infections for the PID patients. Furthermore, C. trachomatis EIA detected more IgG antibodies in the TFI patients than in patients with non-tubal factor infertility. In conclusion, rELISA detected chlamydial antibodies in general, and C. trachomatis EIA detected species-specific antibodies. These EIA tests may be useful in the serodiagnosis of chlamydial infection.     

Variability of cutaneous lymphatic flow rates in melanoma patients

A woman with a small (6-mm gestational sac) interstitial pregnancy had complete resolution after medical therapy alone. A single cycle of methotrexate 50 mg/m2 was used as outpatient treatment without any operative procedure either for diagnosis or intervention. The guidelines that have evolved for selection of women for single dose methotrexate treatment for both intrauterine and tubal ectopic pregnancies may be applicable to interstitial ectopic pregnancy as well. A suggested framework for treatment decisions is presented.     

Chlamydia trachomatis infections

Chlamydia trachomatis is the most common bacterial cause of sexually transmitted disease in the developed countries. The most important implications of genital chlamydia infections involve the reproductive health sequalae of upper genital tract infections in women: pelvic inflammatory disease, ectopic pregnancy, and infertility, infection by this organism is insidious, symptoms are absent or minor among most infected women and many man. This large group of asymptomatic and infectious persons sustains transmission within a community. This review discusses the epidemiology, of sexually transmitted chlamydial infections, the spectrum of clinical manifestations and their sequelae, the laboratory diagnosis of genital chlamydiasis, antibiotic treatment and prevention.     

Chlamydial and gonococcal serology in women with tubal infertility

Sera from 81 infertile women with tubal pathology and 40 controls were tested for the presence of antibodies against Chlamydia trachomatis & Neisserria gonorrhoeae. Indirect immunoperoxidase test (Ipazyme kit) & Enzyme linked immuno sorbent assay (ELISA kit) were used for detection of chlamydial & gonococcal antibodies respectively. Antibodies to Ch. trachomatis were found in 74.07% of the infertile women and 5% in control group. Only a very low prevalence (4.93%) of antibodies to N. gonorrhoeae was found is infertile women as compared to nil in control group. Antibodies detection is a sensitive, specific and noninvasive test for diagnosing infertility.     

How to get the most from your iron supplement

BACKGROUND: Tubal effects of methotrexate injections have been poorly reported. CASES: Three fallopian tubes were examined with light microscopy 9-13 months after tubal methotrexate injection (one case) and intramuscular methotrexate injection (two cases) given for the treatment of unruptured ectopic pregnancies. No evidence of tubal damage was found. CONCLUSION: These three cases confirm previous experimental and clinical data showing the absence of a direct adverse effect of methotrexate on the fallopian tubes in the treatment of ectopic pregnancy.     

Symptom-giving pelvic girdle relaxation of pregnancy, postnatal pelvic joint syndrome and developmental dysplasia of the hip. The Norwegian Association for Women with Pelvic Girdle Relaxation (Landforeningen for Kvinner Med Bekkenl?sningsplager)

OBJECTIVES: To describe the clinical characteristics and outcomes of a large group of women with symptom-giving pelvic girdle relaxation of pregnancy and postnatal pelvic joint syndrome. To determine if there is an increased incidence of developmental dysplasia of the hip in the children of women with such pelvic problems. METHODS: A postal survey of 1,609 Norwegian women registered as having pregnancy-initiated pelvic joint pain. The response rate was 79% and from the answers 1,115 women were defined as having had symptom-giving pelvic joint syndrome of pregnancy and/or postnatal pelvic joint syndrome. RESULTS: Pelvic pains began in the first pregnancy in 74% of the respondents usually beginning in the first trimester. Pelvic pain worsened with subsequent pregnancies and persisted for a mean of 6.25 years, often causing major incapacity and lifestyle changes. Rest and physical supports brought temporary relief only. Sacroiliac joints and the symphysis pubis were the commonest sites of pain but peripheral joints were also often affected. There was a strong family history of both pelvic joint syndrome and developmental dysplasia of the hip. The incidence of hip dysplasia in the children of women surveyed was 45/1,000 which is 5 times the Norwegian incidence. CONCLUSION: Pelvic joint syndrome nearly always follows pelvic girdle relaxation of pregnancy and may have prolonged debilitating effects which do not respond long term to current therapies. The incidence of developmental dysplasia of the hip in the children of these women was high. A genetic susceptibility to joint dysfunction in both mother and fetus, possibly due to an aberration of relaxin physiology, is surmized. Identification of possible relaxin receptor changes in affected joints is a hypothesis worthy of testing with a view to the design of selective relaxin receptor modulators in pregnancy.     

Circulating antibodies to Chlamydia trachomatis in women: relationship to antisperm and antichlamydial antibodies in semen of male partners

The relation between antibodies to Chlamydia trachomatis and spermatozoa in sera of 112 asymptomatic female partners of infertile couples with no history of C.trachomatis infections and antichlamydial antibodies in semen or antisperm antibodies on ejaculated spermatozoa of their male partners was examined. Samples were tested for immunoglobulin (Ig)A and IgG antibodies to C.trachomatis by enzyme-linked immunosorbent assay; antisperm antibodies in sera and on motile spermatozoa were assayed by immunobead binding. IgG antibodies to C.trachomatis were detected in 24 (21.4%) of the women; only five (4.5%) women were positive for antichlamydial IgA. Antichlamydial IgG was detected in sera from 10 (40.0%) of 25 women whose partners had antichlamydial IgA in semen as opposed to 14 (16.1%) of 87 women whose partners' semen were negative for this antibody (P = 0.02). Similarly, antichlamydial IgG was detected in sera from five (50%) of 10 women whose partners had antichlamydial IgG in semen as opposed to 19 (18.6%) of 102 women whose partners' semen lacked this antibody (P = 0.03). There was no relation between antichlamydial antibodies in women and circulating antichlamydial antibodies in men. A strong correlation (P = 0.001) was observed between IgG antichlamydial antibodies in a woman's serum and antisperm antibodies on ejaculated spermatozoa of her partner [8 of 14 (57.1%) versus 16 of 98 (16.3%)]. Conversely, antichlamydial antibodies in a woman's serum was unrelated to the presence of antisperm antibodies in either her own serum or her partner's serum. The data demonstrate that chlamydial infections of the male genital tract, which are associated with antisperm antibody formation on ejaculated spermatozoa, are likely to be transmitted to the female partner. In contrast, the presence of antichlamydial antibodies in sera does not necessarily appear to indicate an infection of the genital tract and is not associated with the heterosexual transmission of C.trachomatis.     

Diagnostic value of hysterosalpingography and laparoscopy in infertile women

Tubal pathology with tubal blockage due to the pelvic inflammatory diseases is one of the most frequent causes of infertility in a woman [1]. The two most important diagnostic procedures which are used for evaluation of tubal patency are hysterosalpingography and laparoscopic hydrotubation [4]. SUBJECT: The aim of the study was the comparison of hysterosalpingographic and laparoscopic findings and determination of accuracy of these two procedures in the diagnosis of tubal patency. MATERIAL AND METHODS: We studied and compared the results of hysterosalpingography and laparoscopy in 102 infertile women who were operated on at the Narodni Front Hospital of Gynaecology and Obstetrics in Belgrade during 1993 and 1994. Of 102 operated women 47 women were with primary infertility and 55 with secondary infertility. The patients were from 20 to 41 years of age, the average 28 +/- 2.4 years. RESULTS: Of one hundred and two operated women tubal blockage was found in 94 (92.1%) patients. Unilateral hydrosalpinx was found by hysterosalpingography in 16 (15.7%) subjects and bilateral hydrosalpinx in 30 (29.4%) women. Unilateral hydrosalpinx was found by laparoscopy in 17 (16.1%) patients and bilateral hydrosalpinx in 32 (31.4%) subjects. The concordant findings by hysterosalpingography and laparoscopy in the diagnostics of unilateral hydrosalpinx were found in 76.5% of cases, and in bilateral hydrosalpinx in 70.4%. This difference was not statistically significant. Unilateral tubal blockage was identified by laparoscopy in 26 (25.5%) patients and bilateral in 27 (26.5%) subjects. The concordant findings by hysterosalpingography and laparoscopy in unilateral tubal blockage were found in 61.5% of cases, and in bilateral tubal blockage in 70.4% of women. The total concordant findings by hysterosalpingography and laparoscopy in tubal blockage were found in 65.7 of cases, and concordant findings after hysterosalpingography and surgery were noted in 61.7% cases. The findings by laparoscopy and surgery were in harmony in 86.3% patients. Ovarian abnormalities were found by laparoscopy and surgery in 22 (21.6%) women. Pelvic adhesions were found by laparoscopy in 42 women of 49 patients in whom pelvic adhesions were found during the operation. Uterine congenital anomalies were found by laparoscopy in 3 (2.9%), women and by hysterosalpingography in 6 (5.9%) patients. DISCUSSION: Of 102 operated women tubal blockage was found in 94 (92.2%) women. Unilateral tubal blockage was found in 38 (40.4%) patients, and bilateral tubal blockage in 56 (59.6%) subjects. Hysterosalpingographic and laparoscopic hydrotubation findings in the diagnosis of tubal patency were concordant in 65% of cases, hysterosalpingographic and operative findings in 61.7% of patients, and laparoscopic and operative findings in 86.3% of subjects. Although concordant findings of 65.7% were noted in this study, which were similar to findings of other authors, the percentage of 62.5% [4], and 76% was observed [5]. During the operation pelvic adhesions were found in 49 patients, and laparoscopic in 42 women only. Ovarian abnormalities were found by laparoscopy in 22 (21.6%) patients, while uterine fibroid was found in 10 (9.8%) subjects. Uterine congenital anomalies were found by hysterosalpingography in 6 (5.9%) cases and by laparoscopy only in 3 (2.9%) patients. The advantage of visual hysterosalpingography seems to be in identification of some congenital uterine anomalies. However, the advantage of laparoscopy is identified by the possibility of visualisation of some other pelvic abnormalities which may be the cause of infertility. CONCLUSION: There are some hysterosalpingographic and laparoscopic advantages and disadvantages in the diagnosis of infertility in women. Only by using both procedures accurate results can be achieved in the tubes, the uterus and the ovary, that can be a cause of infertility in women.     

Chlamydia and the Curtis-Fitz-Hugh syndrome

Ten women with acute right upper-quadrant abdominal pain but negative results for biliary investigations had a current or past history of pelvic inflammatory disease. A diagnosis of the Curtis-Fitz-Hugh syndrome was made and was confirmed in five patients by laparoscopy. Neisseria gonorrhoeae was not isolated from the cervical and urethral swabbings of seven patients tested. Chlamydia trachomatis was isolated from the endocervical canal in one of six patients examined. Of sera from nine patients tested by a micro-immunofluorescence test, nine and six samples respectively showed type-specific IgG and IgM antibodies against C trachomatis serotypes D-K. Type-specific IgG and IgA antibodies were also detected in the cervical and urethral discharge of two out of five patients and in the peritoneal aspirate of two. The presence of high titres of IgG or IgM in sera and IgG or IgA in the local discharges of our patients suggests that C trachomatis was probably the cause of the CFH syndrome.
