Pelvic infections are not active for several weeks or months with the exception of  chronic colonization by C. trachomatis  infection with rare organisms, such as ⚜ tuberculosis ⚜ actinomycosis. May start as a lower genital tract infection  Ascending infection from the bacterial flora on the mucosal surface of the vagina and cervix (99%)  Bacterial colonization and infection of the endometrium and fallopian tubes  may spread to ovaries, nearby peritoneum & adjacent soft tissues such as broad ligament & pelvic blood vessels MODE of SPREAD  Local/ Direct Extension  Lymphatics  Hemtogenous EPIDEMIOLOGY  Acute pelvic inflammatory disease is the MC gynecologic condition that results in hospitalization of women of reproductive age in the United States.  Rare in women the following women ⚜ Women without menstrual periods  Hence rare in:  Prepubertal females  Pregnant women  Postmenopausal women ☀ If PID is diagnosed, other associated conditions are usually discovered such as ❧ genital malignancies ❧ diabetes ❧ concurrent intestinal diseases ☘ diverticulitis ☘ appendicitis ☘ carcinoma ⚜ Women who are NOT sexually active  1% to 2% of all young, sexually active women annually  Most common serious infection of women age 16-25 ⚜ 85% develop spontaneously in sexually active women ⚜ 15% follow procedures that break cervical mucus barrier allowing vaginal flora to colonize the upper genital tract. Procedures include:  endometrial biopsy  curettage  intrauterine device insertion  hysterosalpingography  hysteroscopy  Lack of significant antibody titers explain why teenagers are more likely to develop upper genital tract infection than woman in late 20s  Chamydia more prevalent than gonorrhea (4:1)

If N. gonorrhoeae is the only organism cultured from the tubes, a patient will usually respond rapidly to treatment. Immunologic studies

demonstrated that an antibody against the outer membrane protein of the gonococcus develops in ~70% of women following severe pelvic infection.  The lack of significant antibody titers may help explain why teenagers are more likely to develop upper genital tract disease than women in their late 20s. Recovery rates  highest recovery rates occur in young, urban women in the United States. PATHOLOGY  produces an intense inflammatory reaction in the tubes  narrowing or occlusion of the tubal lumen d/t presence of necrotic debris and purulent material.  Cellular destruction is much more extensive than the reaction associated with a chlamydial infection Chlamydia trachomatis an intracellular, sexually transmitted bacterial pathogen ratio of chlamydial to gonococcal PID diagnosed by laparoscopy of 4:1 Involved in at least 40% of women who are hospitalized with PID ~30% of women with documented acute cervicitis secondary to chlamydia subsequently develop acute pelvic inflammatory disease. May remain in the fallopian tubes for months after initial colonization while N. gonorrhea only stay for days Primary infection:  self-limited with mild symptoms Tissue destruction is associated with Cell-Mediated Immune Mechanisms  Chlamydia produces a disruption of the tubal mucosa by an immunopathologic mechanism rather than by a direct cytotoxicity, as is the case with N. gonorrhoeae.  host cell-mediated immune response to a chlamydial heat shock protein produces the disruption of the tubal mucosa  Women with antibodies to chlamydial heat shock protein ⚜ more likely to develop tubal scarring and fitz-hughcurtis syndrome Chlamydia can still be isolated months after initial infection unlike gonorrhea, you can’t isolate it anymore SILENT OR ATYPICAL PID

Asymptomatic inflammation of the upper gentital tract often a/w chlamydial infection may be the more common form of upper tract infection than the symptomatic PID SEQUELAE of repeated Asymptomatic Chlamydial Infection ⚜ Tubal infertility ⚜ ectopic pregnancy   risk 3-6 times

Mycoplasma hominis route of spread of mycoplasmas is via the parametria rather than the mucosa primary upper genital tract infection is in the parametria and the tissue surrounding the tubes, not in the tubal lumen more of a commensal bacterium rather than a pathogen in the oviducts. Histologically, does not appear to produce damage to the tubal mucosa. are not highly pathogenic presence of genital mycoplasmas does not change the clinical presentation and clinical course of acute pelvic inflammatory disease. Endogenous Aerobic & Anaerobic Flora of the Vagina Normal flora of the vagina frequently ascend to colonize and infect the upper reproductive tract. Direct cultures of purulent material are taken from  tubal lumen  posterior cul-de-sac Aerobic organisms  most common organisms are ⚜ nonhemolytic Streptococcus ⚜ Escherichia coli ⚜ group B Streptococcus ⚜ coagulasenegative Staphylococcus Anaerobic organisms  tend to predominate over aerobes  most common anaerobic organisms ⚜ Bacteroides species ⚜ Peptostreptococcus ⚜ Peptococcus  ubiquitous in pelvic abscesses a/w acute pelvic inflammatory disease. ⚜ Tuboovarian complexes and abscesses  more common in women with concurrent bacterial vaginosis or HIV infection.

PATHOLOGY  d/t transperitoneal or vascular dissemination of either the gonococcus or Chlamydia organism to produce the perihepatic inflammation. ⚜ Chlamydia produces the majority of cases.  Other organisms involved ⚜ anaerobic streptococci ⚜ Coxsackievirus  Organisms cause a thinning of cervical mucus and allow bacteria from the vagina into the uterus and oviducts, causing infection and inflammation  inflammation can cause scar tissue to form on Glisson's capsule, a thin layer of connective tissue surrounding the liver. Women with perihepatitis have  higher prevalence of moderate to severe pelvic adhesions  higher prevalence and higher titers of antibodies to the chlamydial heat-shock protein-60.
