Most pelvic inflammatory disease (PID) is caused by the ascent of sexually transmitted disease pathogens from the endocervix. In fact, PID remains the most common serious complication of infection from sexually transmitted bacterial pathogens. PID also may be caused by normal vaginal micro-organisms (such as those associated with bacterial vaginosis) that have overgrown in the vagina. PID has been linked to the occurrence of long-term sequelae, most commonly and most importantly infertility and ectopic pregnancy. In many patients PID may remain undiagnosed and asymptomatic, and may not become evident until such long-term consequences become manifest. We briefly review the epidemiology of PID including case definitions, the prevalence of the problem, and causal pathways and associated risk factors. Risk factors for both PID and its sequelae are discussed in relation to the mechanism of ascent of associated etiologic agents from the lower to the upper genital tract.

Vaginitis is the most frequent gynecological disease. It is characterized by objective and subjective signs of inflammation and differs from bacterial vaginosis (BV) which is an abnormal condition of the vaginal ecosystem caused by the excessive growth of aerobic and anaerobic flora normally present in the vagina with an increased risk of pelvic inflammatory disease (PID). The authors report the results of a study carried out at the Centre for Gynecological Infections at the Clinic of Obstetrics and Gynecology of the University of Parma. 828 patients were enrolled in the study during the period 1985-86 and 1559 patients during the two-year period 1991-92. The aim of the study was to evaluate variations in epidemiological data for vaginitis and bacterial vaginosis in the two periods examined. No significant changes were observed (p > 0.05) with regard to the prevalence of Ca, Tv and BV forms. On the other hand, there was a significant reduction (p < 0.001) in the forms sustained by other microorganisms (above all, streptococcus and enterobacteria) between the first and second periods with a parallel increase in the number of negative cases. The analysis of the age distribution of vaginitis and BV showed a reduction of other microorganisms and an increase in negative vaginal swabs in adults (> 20 years old).

The normal vaginal flora consists of a wide variety of bacteria and the composition of this microflora is influenced by hormonal, metabolic and pharmacological factors. An increased concentration of a mixed anaerobic flora (Mobiluncus, Prevotellae, Peptostreptococci and Gardnerella vaginalis) appears to be an early stage in the development of bacterial vaginosis or in the infection of the upper genital tract. Women with bacterial vaginosis are at increased risk of bartholinitis, skenitis, pelvic inflammatory disease, postpartum and postabortal endometritis, chorioamnionitis and infections following gynecologic surgery or diagnostic procedure.

Anaerobic infections of the upper genital tract are common. Antibiotic regimens designed to inhibit anaerobes markedly reduce morbidity. A vaginal infection associated with an increased concentration of anaerobic bacteria (bacterial vaginosis) has been recently linked to a wide variety of upper genital tract infections. Bacterial vaginosis has an important role in the development of clinical chorioamnionitis, postpartum endometritis, posthysterectomy vaginal-cuff cellulitis, postabortion pelvic inflammatory disease, and upper genital tract infections such as amniotic fluid infection and chorioamnion infection associated with premature delivery.

Spermicides kill a wide range of bacteria and viruses causing sexually transmitted diseases (STDs), including the human immunodeficiency virus (HIV) in vitro, and protect in vivo from infection by gonorrhoea, chlamydia, and pelvic inflammatory disease (PID). In the UK and the US, the most commonly used compound in spermicidal agents is the neutral surfactant nonoxynol-9. Although spermicides reduce the incidence of reinfection by some STDs, an in vivo virucidal action is not supported by convincing data. Among barrier methods, latex condoms provide an impervious barrier in vitro to most STD pathogens, including HIV. Natural condoms made of sheep intestinal membrane can allow passage of hepatitis B viral particles but not HIV in vitro. Several studies have shown protection against cervical gonorrhoea and PID among diaphragm users; however, diaphragm use has been associated with an increased rate of urinary infection and also bacterial vaginosis. It is conceivable that women using oral contraceptives (OCs) do not develop as much tubal damage as women not using OCs because of a modified immunological reaction. A study carried out in Europe showed a statistically significant protective effect against PID of the levonorgestrel-containing IUD as compared with the copper-containing Nova-T. A case/control study of 1028 women in Chicago in 1970 noted admission for PID during the following 7 years of only 1 woman who had been sterilized compared to 9 controls. A case/control study examining risk factors for cervical intraepithelial neoplasia (CIN) in 103 women with biopsy-confirmed CIN II or III did not find an increased risk with either OC or IUD use after adjusting for other known risk factors. After adjustment for age and education, the odds ratio for diaphragm use was .3 and the odds ratio for condom use was .5. Thus, hormonal contraception and tubal ligation give protection to the upper genital tract but not to the cervix.

Forty-one patients with acute pelvic inflammatory disease were evaluated for the coexistence of bacterial vaginosis. Because all patients had a copious purulent vaginal discharge, microscopic criteria could not be used and microbiologic criteria were employed. The vaginal bacterial flora were not consistent with that of bacterial vaginosis, because Lactobacillus and other gram-positive bacteria dominated with colony counts of 10(3) to 10(5) cfu/ml (colony-forming units per milliliter). Endocervical specimens yielded Neisseria gonorrhoeae from 20 patients and Chlamydia trachomatis from 11 patients. Anaerobes were not dominant in any site sampled. A total of 147 bacteria were isolated from the endometrium, 16 (11%) of which were anaerobes. Thus the endogenous bacterial flora were not consistent with that of the microbiologic definition of bacterial vaginosis. N. gonorrhoeae was the most common isolate from the endocervix and endometrium; it was isolated three times more frequently from the endocervix and two times more frequently from the endometrium than was C. trachomatis.

Most of the publications reviewed focus on human papillomavirus (HPV), and a small proportion on herpes simplex virus (HSV), Chlamydia trachomatis, as well as the syndromes of pelvic inflammatory disease and bacterial vaginosis. The present hypothesis associates cervical intraepithelial neoplasia (CIN)-1 with high oncogenic risk HPV types in less than 30% of cases; whereby CIN-2 and CIN-3 are associated with a 90% risk. However, on the basis of HPV types, four categories ['low risk' (HPV 6/11, 42, 43, 44); 'intermediate risk' (HPV 31, 33, 35, 51, 52, 58); 'high risk/HPV 16'; and 'high risk/HPV 18'] for the associated risk for a high-grade lesion or an invasive cancer can also be defined. In practice it appears efficient to re-evaluate patients with oncogenic types in association with low-grade cytology, as well as women with high-grade cytology or suspicious colposcopy in narrow intervals. Several reports have suggested that HPV genital infections are multifocal; however, HPV DNA was also found in the lymph nodes and in the granulocytes of women with cervical cancer, in ovarian and endometrial tissue, in tumours of the urinary bladder, and in mammary ductal carcinoma.

The notion of safe sex currently denotes protection from unintended pregnancy, HIV, and other sexually transmitted diseases (STD). Modern parallel complications of sexual activity should therefore be considered when selecting contraceptives. This article assesses the impact of hormonal contraception, spermicides. barrier methods, IUDs, and douching on the pathogenesis of STDs and HIV. It discusses the direct and indirect effects of contraception methods on clinical physiology and host immune responses while considering the possible consequences on maternal and infant health if pregnancy results from the use of ineffective contraception. It is concluded that significant interactions exist between forms of contraception and STDs and HIV which may be beneficial or harmful to women. For example, oral contraceptive (OC) use may reduce risks of pelvic inflammatory disease and its sequelae, but may increase risks of chlamydia infection. Barrier methods, especially when combines with spermicides, can reduce the risk of STDs/HIV if used consistently. The combined use of OCs and condoms offers serious defense against both unintended pregnancy and STDs/HIV. IUDs also seem safe and effective in women at low risk for reproductive tract infection. Periodic screening and treatment for prevalent STDs and possible bacterial vaginosis can protect the health of individuals and their sexual contacts. Finally, more research is needed on the reproductive and infectious disease repercussions of human sexuality, while counseling and care for family planning and infectious disease protection are recommended for those who are sexually active.

Induced abortion is one of the most frequent surgical procedures in the UK. Even though it is considered safe, it sometimes has complications and long-term sequelae. Pelvic inflammatory disease (PID) is the most prevalent complication and can lead to chronic pelvic pain, pain during intercourse, infertility, and a higher risk of ectopic pregnancy. Chlamydia trachomatis is perhaps the leading etiologic agent for PID among women who have undergone induced abortion and who develop PID. Gonorrhea is another major etiologic agent for PID. Strategies used to try to reduce pelvic infection revolve around administration of antibiotic prophylaxis based on demographic features and on the presence of certain organisms in the genital tract that may increase their risk (e.g., C. trachomatis and Neisseria gonorrhoeae) and universal antibiotic prophylaxis for all women undergoing abortion. Most of the literature suggests that antibiotic prophylaxis does provide some protection against PID but does not clearly indicate who should be screened and for which pathogens and who should be treated and with which antibiotics. Demographic features useful for identifying who should receive antibiotic prophylaxis are: a history of PID, single status, nulliparity, and youth (especially reliable for chlamydial infection). Screening for bacterial vaginosis involves diagnosis based on 3 of 4 criteria: characteristic vaginal discharge, positive amine test, raised vaginal pH, and the presence of clue cells on microscopy of wet or stained preparations of vaginal discharge. Since C. trachomatis is the most important pathogen, drugs sensitive to it should be administered: tetracyclines and erythromycin. Screening women seeking abortion for sexually transmitted diseases (STDs) provides an opportunity to educate them about STDs and treatment compliance and to contact their partners for investigation, treatment, and contact-tracing to reduce the STD-infected pool in the community.

The role of quinolones in sexually transmitted diseases is still being defined. In vitro and in vivo efficacy of established agents against gonorrhoea after a single oral dose is well established, although problems with emerging resistance have been identified. However, among these agents only ofloxacin is reliably active against Chlamydia trachomatis infection, and only as a course of treatment. Preliminary trials with sparfloxacin are encouraging. Other new agents show potentially useful in vitro activity, but clinical studies are awaited. To date, clinical activity of quinolones in bacterial vaginosis has been disappointing. The efficacy of newer agents with anaerobic activity will be of interest. Chancroid can be cured with ciprofloxacin or ofloxacin; resistance has been reported, but is not yet clinically significant. Ofloxacin appears to be effective therapy for pelvic inflammatory disease, without the need for additional anaerobe cover. The possibility of improved clinical efficacy justifies further in vitro and in vivo studies.
