Recovery of Chlamydia trachomatis from the endometrium of women at risk for chlamydial infection.

Chlamydia trachomatis is the most common sexually transmitted disease in Western Society today and is a major cause of salpingitis and tubal infertility. However, the frequency with which it produces upper genital tract infection in asymptomatic women has not been determined. Endometrial, endocervical, and urethral cultures for C. trachomatis were obtained from 60 women who were at risk for chlamydial infection but who did not have evidence of endometritis or salpingitis on physical examination. Chlamydia was isolated from the lower genitourinary tract in 26 (43%) and from the endometrium in 12 (20%). Thus 12 of 29 (41%) women infected with C. trachomatis had endometrial infections. Upper genital infections appear to be common in women at risk for chlamydial infection, and spread to the upper tract may occur shortly after the infection is acquired.

The epithelial pathology of bovine genital tuberculosis.

The histopathology of the uterine and salpingeal epithelium of five cows affected with genital tuberculosis was studied. Both optical and scanning electron microscopy were used and the results were compared. Various forms and degrees of cellular lesions are described, including hypertrophy, flattening, detachment, nuclear protrusions and alterations of the cilia. In the different sites considered (uterus: intercaruncular and caruncular areas; salpinges: isthmus and ampulla) various characteristic lesions were observed.

Local induction of tumor necrosis factor as a molecular mechanism of mucosal damage by gonococci.

Tumor necrosis factor (TNF) is an endogenously produced cytokine that plays a critical role in mediating septic shock and multi-organ failure, but previous studies of the role TNF in disease have not examined its role in mucosal disease processes. In an experimental model of acute gonococcal salpingitis, gonococcal infection of human fallopian tube mucosa resulted in increased mucosal production of TNF. Recombinant human TNF-alpha damaged fallopian tube mucosa in a dose-response manner and produced epithelial damage with the same ultrastructural features as those observed in gonococcal infection. Blocking production of TNF during gonococcal infection diminished the extent of damage to fallopian tube mucosa. In addition to mediating systemic disease, such as septic shock, TNF is also produced locally, and can play a critical role in mediating mucosal disease processes, such as acute gonococcal salpingitis.

Role of bacterial vaginosis-associated microorganisms in endometritis.

OBJECTIVE: Our goal was to define the role of bacterial vaginosis and bacterial vaginosis-associated microorganisms in endometritis. STUDY DESIGN: Endometrial biopsies were obtained for histologic and microbiologic study from 178 consecutive women with suspected pelvic inflammatory disease, and 85 of them underwent laparoscopy to diagnose salpingitis. RESULTS: Histologic endometritis was confirmed in 117 (65%) of the women. Among women who underwent laparoscopy, salpingitis was present in 68% of those with and 23% of those without endometritis. Some but not all bacterial vaginosis-associated microorganisms were linked with endometritis. By logistic regression analysis, after adjustment for bacterial vaginosis and isolation of Neisseria gonorrhoeae and Chlamydia trachomatis, endometritis was associated with endometrial N. gonorrhoeae (odds ratio 5.7, 95% confidence interval 1.8 to 17.5), C. trachomatis (odds ratio 4.8, 95% confidence interval 1.3 to 18.2), anaerobic gram-negative rods (odds ratio 2.6, 95% confidence interval 1.1 to 5.7), and nonwhite race (odds ratio 2.3, 95% confidence interval 1.1 to 4.8). CONCLUSIONS: The association of anaerobic gram-negative rods with endometritis, after adjustment for bacterial vaginosis, N. gonorrhoeae, and C. trachomatis, supports the role of these microorganisms in the etiology of histologic endometritis among women with clinically suspected pelvic inflammatory disease.

Surgical considerations in the diagnosis and treatment of pelvic inflammatory disease.

Pelvic inflammatory disease continues to be a common finding in young women with lower abdominal pain. Typical emergency room pelvic inflammatory disease, with classic symptoms of pain, fever, and a history of high-risk sexual behavior, is easily diagnosed with a high degree of specificity. However, the majority of patients with pelvic inflammatory disease have atypical symptoms, and their condition may be incorrectly diagnosed and treated. Careful attention to the physical signs of pelvic infection and the evaluation of the vaginal secretions for leukocytes improves diagnostic accuracy. Liberal use of diagnostic laparoscopy to confirm the possibility of acute salpingitis is recommended in young women, who have much to lose from a case of untreated salpingitis. Outpatient treatment with a beta-lactam antibiotic followed by a course of doxycycline adequately treats patients with N. gonorrhoeae and C. trachomatis infections. However, patients with suspected anaerobic upper genital tract infection such as those infections associated with tubo-ovarian abscess or IUD use should be admitted for parenteral antibiotic therapy and observation. Laparotomy and extirpative surgery should be reserved for seriously ill patients with generalized peritonitis associated with rupture of a tubo-ovarian abscess and for patients who do not respond to antibiotic therapy. Sound judgment regarding the extent of extirpative surgery, taking into consideration the wishes of the patient with respect to future fertility and hormone production, will lead to an acceptable outcome.

The risk of pelvic inflammatory disease in women using intrauterine contraceptive devices as compared to non-users.

The frequency of women using an intrauterine contraceptive device (I.U.D.) among 515 patients presenting with acute, laparoscopically verified salpingitis, has been compared with the corresponding frequency in 741 sexually active women who were matched to the patients by date of birth, domicile, and socioeconomic status. The frequency of I.U.D. use was significantly (P less than 0-001) higher in the patients than in the controls. It was estimated that the relative risk of acute salpingitis for any woman using an I.U.D. was 3-fold as compared to non-users. For women using I.U.D.s who had not been pregnant at any time, the corresponding risk was found to be 7-fold.

Prevalence of Chlamydia trachomatis, Chlamydia psittaci and Chlamydia pneumoniae antibodies in blood donors and attendees of STD clinics.

OBJECTIVE: To estimate the prevalence of Chlamydia trachomatis, C. psittaci and C. pneumoniae antibodies in sera from altogether 931 blood donors, patients with symptoms of urethritis, assumed salpingitis and sexually acquired reactive arthritis (SARA), and women with fertility problems. METHODS: IgG antibodies to C. trachomatis, C. psittaci and C. pneumoniae were determined by microimmunofluorescence (MIF) tests. All patients were also tested for genital C. trachomatis infection using direct immunofluorescence (DIF) tests. RESULTS: The DIF-positive cases had a significantly (p < 0.0001) higher prevalence of C. trachomatis antibodies than the DIF negatives, i.e. 88.5% versus 14% in men with urethritis, 94.3% versus 36.4% in women with salpingitis, 66.7% versus 16.7% in SARA patients and 90.6% versus 20.8% in women with fertility problems. Antibody reactivity to all three chlamydial species was found significantly (p < 0.0001) more often in the patient groups and in those with a DIF-confirmed genital C. trachomatis infection than in blood donors. CONCLUSIONS: Presence of serum antibodies to C. trachomatis is tightly associated with the presence of chlamydiae in the genital tract, which also influences the cross-reactivities occurring in the MIF tests between chlamydial species.

[Antibiotic prevention in gynecology. Concentrations of ceftizoxime in the serum, myometrium, endometrium and fallopian tubes].

34 patients received an intravenous bolus injection of 2 g ceftizoxime over 5 min at various times before abdominal or vaginal hysterectomy. Ceftizoxime concentrations in myometrium were substantially higher than in salpinges and endometrium. Tissue concentrations of 4 micrograms/g could be maintained for at least 3 hours. The ceftizoxime tissue concentrations attained in myometrium, endometrium and salpinges justify therapeutic studies and controlled prospective clinical trials on the prevention of postoperative wound infections with this antibiotic.

[Postcoital IUD insertion, a review].

Following the development of hormonal interception after coitus the post-coital insertion of an intrauterine contraceptive device was proposed by Tatum . The advantage of this treatment is the avoidance of the ingestion of large doses of estrogen which causes much nausea and vomiting although it is a very effective post-coital method of contraception. The recently proposed alternative administration of 200 micrograms Ethynol Estradiol combined with 2 mg of DL norgesterol in 2 equal doses at 12 hour intervals has the same disadvantage of a high percentage of side effects. The post-coital insertion of an intrauterine contraceptive device is the first method which is effective up to five days following unprotected intercourse which is three days longer than treatment by estrogen. In addition the method can be offered to women who would want to continue to wear the intrauterine contraceptive device for long term contraception. The disadvantage of the post-coital insertion of an intrauterine contraceptive device is the ability of serious complications if the patient has a vaginal or venereal infection or an asymptomatic cervicitis or salpingitis. Following appropriate physical examination women who present themselves for post-coital treatment are selected. Cases of rape are usually not suitable for treatment with intrauterine contraceptives devices. However, when cases of rape are seen early enough the appropriate investigations may be done and the treatment with the intrauterine device started within five days. The potential risk of future infertility must be considered since salpingitis is 7 times more common in nulliparous wearers of intrauterine devices than in nulliparous non-wearers. Young sexually active nulliparous women especially of lower socio economic background are patients with a high risk. Over 70% of the women who present themselves for interception treatment are nulliparous.(ABSTRACT TRUNCATED AT 250 WORDS)

Expression and regulation of interleukin-8 in human fallopian tubal cells.

OBJECTIVE: The human fallopian tube creates the microenvironment for fertilization and early embryogenesis. Salpingitis may result in infertility and ectopic pregnancy by causing tubal blockage and hydrosalpinx. To better understand the relationship between infectious inflammation and tubal damage, we investigated the expression and regulation of interleukin-8 in human tubal epithelial and stromal cells in culture. STUDY DESIGN: Human fallopian tube epithelial and stromal cell cultures were used to measure interleukin-8 messenger RNA and interleukin-8 protein levels at basal conditions and after stimulation with interleukin-1alpha and tumor necrosis factor-alpha. Northern blot analysis and enzyme-linked immunosorbent assay were used to evaluate messenger RNA and protein levels, respectively. RESULTS: Tubal epithelial cells expressed high levels of interleukin-8 messenger RNA and secreted significantly more immunoreactive interleukin-8 into culture medium than did tubal stromal cells (2065 +/- 153 pg/mg vs 530 +/- 56 pg/mg of total protein, P <.01). Interleukin-1alpha and TNF-alpha treatments induced a concentration-dependent increase in interleukin-8 messenger RNA expression in both epithelial and stromal cells. However, at the protein level, although interleukin-1alpha and tumor necrosis factor-alpha treatments increased the secretion of interleukin-8 from stromal cells significantly, similar treatments had no effect on interleukin-8 secretion from epithelial cells. CONCLUSION: The expression of interleukin-8 in human tubal epithelial and stromal cells is different. Interleukin-8 expression of tubal epithelial and stromal cells in response to inflammatory cytokines such as interleukin-1alpha and tumor necrosis factor-alpha also varies. This may be important in the pathogenesis of salpingitis.

Pelvic inflammatory disease. Current diagnostic criteria and treatment guidelines.

Pelvic inflammatory disease (PID) is a common infection in women of reproductive age. PID is actually a spectrum of disease, beginning with cervicitis and progressing to endometritis and eventually salpingitis. Sequelae include ectopic pregnancy, infertility, chronic pelvic pain, hydrosalpinx, and tubo-ovarian abscess. Neisseria gonorrhoeae and Chlamydia trachomatis are the primary causes of PID. Chlamydial infection may be asymptomatic, and the resulting salpingitis is often referred to as "silent PID." Polymicrobial infection with other organisms (eg, anaerobes, facultative aerobes) may be initiated by gonorrhea, chlamydial infection, or both. Early recognition of infection, prompt institution of appropriate antibiotic therapy, and proper follow-up are important to prevent the sequelae of PID. Patient education is essential to reduce the incidence of PID.

Comparison of cefotaxime, cefoxitin and clindamycin plus gentamicin in the treatment of uncomplicated and complicated pelvic inflammatory disease.

Patients with uncomplicated pelvic inflammatory disease (PID) (acute salpingitis and no pelvic masses) were randomly assigned for treatment with either cefotaxime or cefoxitin. A clinical cure was achieved in 17 of 20 cases (82%) and 19 of 22 cases (84%), respectively. Within the complicated PID group, patients were assigned to two subgroups: those with a tubo-ovarian complex (26 patients), and those with a tubo-ovarian abscess (32 patients), as confirmed by ultrasonography or surgery. Patients within each of these two subgroups were then randomly assigned for treatment with either cefotaxime or clindamycin plus gentamicin. Within the tubo-ovarian complex subgroup, a clinical cure was achieved in 11 of 13 cases (85%) treated with cefotaxime and 10 of 13 cases (77%) treated with clindamycin plus gentamicin. Within the tubo-ovarian abscess subgroup, a clinical cure was achieved in 12 of 16 cases (75%) treated with cefotaxime and 11 of 16 cases (69%) treated with clindamycin plus gentamicin. No differences in any category were statistically significant. Specimens for culture were obtained from the endocervix, endometrium, and when possible, the cul-de-sac, fallopian tubes, and abscess. Neisseria gonorrhoeae (33%) was isolated more frequently than Chlamydia trachomatis (12%) in patients with PID, and neither of these organisms was isolated with any increased frequency in patients with complicated PID. The majority of the patients were considered to have polymicrobial infection. Cefotaxime was as efficacious as cefoxitin and clindamycin plus gentamicin for the treatment of acute salpingitis, tubo-ovarian complex and tubo-ovarian abscess.

The effect of a single oral dose of azithromycin on chlamydial infertility and oviduct ultrastructure in mice.

Azithromycin has been recommended for the treatment of human chlamydial genital tract infections because of the sustained, chlamydicidal levels of the antibiotic which can be achieved after a single dose. The effect of single dose azithromycin on the prevention or reversal of chlamydial-induced damage to the oviduct or to fertility was assessed in a mouse model of chlamydial salpingitis which closely mimics the human disease. C3H mice were treated with progesterone and then inoculated under the ovarian bursa with a human genital tract isolate of Chlamydia trachomatis, serovar F. Azithromycin at doses from 135-250 mg/kg was administered by oral intubation. Morphological damage to the oviduct lumen was assessed by scanning electron microscopy, while fertility was assessed by breeding experiments. Treatment of mice two or seven days after infection with 135 mg/kg azithromycin completely reversed chlamydial-induced ultrastructural changes and infertility. Treatment 12 or more days after infection, at doses as high as 250 mg/kg, failed to prevent infertility. The onset of fertility correlated with the loss of ciliated epithelia from the oviduct. However, the regeneration of ciliated epithelia following azithromycin treatment did not necessarily restore tubal patency. These results, if true for women also, indicate the need for rapid, effective antibiotic therapy for chlamydial salpingitis to prevent infertility and other sequelae of tubal damage.

Exposure to diethylstilbestrol during pregnancy permanently alters the ovary and oviduct.

To determine the effects of transplacental exposure to diethylstilbestrol (DES) on the ovary and oviduct of the CD-1 mouse, timed pregnant mice were injected subcutaneously with DES (100 micrograms/kg) on Days 9 through 16 of gestation and female offspring sacrificed from 4 weeks to 10 months of age. Following DES exposure, ovarian alterations such as inflammation, a prominent interstitial compartment composed of medullary tubule-like structures, and intra- and para-ovarian cysts from mesonephric remnants were observed. In addition, there were oviductal abnormalities including malformation. As reported previously, the oviduct was closely adherent and coiled around the ovary in a similar position to that seen in the fetal mouse. This malformation was termed developmental arrest of the oviduct (DAO) and was a consistent finding in female offspring exposed prenatally to DES (100 micrograms/kg). Increased prevalence of salpingitis and microscopic alterations in the oviduct were also observed. Oviductal epithelium was mostly secretory type with basal vacuoles. In some cases, oviductal epithelium was hyperplastic and formed mucosal folds resembling glands which extended through the muscularis (diverticulosis). The extent of the adenomatous mucosal folds and the degree of extension through the muscularis increased with the age of the animal (100% at 10 months). Some characteristics of this abnormality resembled salpingitis isthmica nodosa, a lesion described in women which is associated with ectopic pregnancies and subfertility. Gross and microscopic changes in the oviduct were more consistent than were the changes among other portions of the reproductive tract of DES-treated mice previously reported. Since subfertility has been described in this mouse model as well as in prenatally DES-exposed women, the data presented in this report may help in evaluation of the reported reduced fertility in exposed patients as well as other infertility patients.

Cutaneous ciliated cyst: a case report with immunohistochemical evidence for dynein in ciliated cells.

Cutaneous ciliated cysts (CCCs) are rare benign lesions predominantly occurring in the lower limbs of young women. We observed such a lesion in the perineal region of a 12-year-old girl. The histogenetic interpretation of CCCs is controversial. The similarity of the epithelial lining of the cyst to the salpingeal epithelium supports the hypothesis of a Müllerian heterotopia. Strong dynein positivity observed immunohistochemically in the apical portion of CCC lining cells suggests the integrity of the ciliary apparatus. There was a marked similarity between a CCC and normal salpingeal epithelium in the mode of staining for dynein, whereas the dynein reactivity of bronchial epithelial cells showed larger cytoplasmic aggregates of positive material in proximity to the nucleus. No immunohistochemical staining for estrogen or progesterone receptors was identified in our observation, although this finding could have supported the Müllerian histogenetic hypothesis. To the best of our knowledge, this is the first time that antidynein immunohistochemistry has been applied to paraffin-embedded samples from human surgical pathology.

Clues to the pathogenesis of fallopian tube carcinoma: a morphological and immunohistochemical case control study.

The purpose of this study was to identify histopathological fallopian tube changes that might be related to the development of fallopian tube carcinoma (FTCA). Each of 14 unilateral cases of the latter was matched with 2 controls for age, hospital, and year of diagnosis. The uninvolved fallopian tube from patients with FTCA, all of which were of serous type, was compared to fallopian tubes from the same side in 28 matched controls. The features evaluated included plical bridging, trapped gland-like structures, inflammation, epithelial stratification, tufting, nuclear atypia, plical atrophy, luminal dilatation, and presence or absence of in situ carcinoma. The significant changes (p < 0.05) in the contralateral tubes of patients with FTCA were luminal dilatation (p = 0.0004), plical atrophy (p = 0.0015), and chronic inflammation (p = 0.0089). FTCA may therefore develop in tubes demonstrating histologic features of chronic healed salpingitis, findings that reflect bilateral tubal disease which apparently antedates the development of the FTCA. p53 stains were strongly positive in 9 of 14 FTCAs and in 5 of 6 foci of in situ carcinoma found in the tubes with unilateral FTCA. No p53 staining was found in any of the contralateral tubes. Serous FTCAs may be etiologically related to antecedent bilateral healed chronic salpingitis and arise from in situ carcinoma in a background of atrophy.

Chlamydia trachomatis infection of human fallopian tube organ cultures.

The pathogenic events that precede Chlamydia trachomatis salpingitis in the human fallopian tube have not been fully described. We used a model of human fallopian tubes in organ culture (HFTOC) infected with strain E/UW-5/CX of C. trachomatis to study these events. The model supported sustained C. trachomatis infection as demonstrated by recovery of viable C. trachomatis from medium and tissue over 5-7 d. However, the level of infectivity was low. Maximal infection occurred at 72 h after initial inoculation. In contrast to gonococcal infection of the HFTOC, C. trachomatis did not damage overall ciliary function of HFTOC. However, a local direct cytotoxic effect characterized by loss of microvilli and disruption of cell junctions was noted when multiple chlamydial elementary bodies attached to mucosal cells. Beginning at 24 h, and continuing throughout the course of C. trachomatis infection of HFTOC, ruptured epithelial cells releasing elementary bodies were noted. Chlamydial inclusions were seen in the mucosa by 72 h in approximately 6% of both ciliated and nonciliated epithelial cells. Mucosal inclusions contained all forms of the C. trachomatis developmental cycle. These data suggest that factors present in the human fallopian tube may limit susceptibility to chlamydial infection but support the use of the HFTOC model in the study of the pathogenesis of C. trachomatis salpingitis.

Experimental infection of the genital tract of female grivet monkeys by Mycoplasma hominis: effects of different routes of infection.

In a previous study we produced acute salpingitis and parametritis in grivet monkeys by inoculation of Mycoplasma hominis directly into the uterine tubes. With the purpose of examining in the same animal model the effect of more natural routes of infection, six female grivet monkeys were inoculated, two by two, with M. hominis by the following methods: (experiment A) into the uterine cavity through the cervical canal; (experiment B) into the uterine cavity by the same route, but after ligature of the isthmus of the uterine tubes had been performed and followed by curettage of the endometrium; and (experiment C) into the cervical epithelium. Whereas the animals in experiment A developed no or only very slight signs of infection, all monkeys in experiments B and C developed pronounced gross and microscopic inflammatory lesions of the uterine tubes and parametria, together with a significant antibody response. It is concluded that ascending M. hominis infection of the genital tract must be preceded by mechanical injury of the epithelial barrier, and that subsequent spread of the infection occurs via blood and lymph vessels rather than by the canalicular route. The inflammatory genital tract disease produced experimentally with M. hominis in grivet monkeys is very similar in its pathogenesis and pathology to the type of salpingitis caused in humans by microorganisms other than Neisseria gonorrhoeae and Chlamydia trachomatis.
