Incidence, prevalence, and trends of acute pelvic inflammatory disease and its consequences in industrialized countries

We studied 204 women with acute pelvic inflammatory disease to delineate further the causes of that illness. Gonococci were recovered from 91. Gonococcal pili antibody rose or fell significantly in 12 of 18 patients with positive cultures and only two of 19 who had negative cultures and smears for Neisseria gonorrhaoea(P smaller than 0.005). N. gonorrhoeae was found in peritoneal exudate from eight of 21 patients with, and none of 33 without, cervical gonococcal infection. Among patients with severe disease, other bacteria were recovered from peritoneal exudates from five of 16 with, and 19 of 22 without, cervical gonococcal infection (P smaller than 0.025). Mixed anaerobic and aerobic bacterial peritoneal infection was common in nongonococcal pelvic disease. The most common species recovered were Bacteroides fragilis, peptostreptococci, and peptococci. Tuboperitoneal gonococcal infection probably causes pelvic inflammatory disease in most patients with cervical gonococcal infection, whereas polymicrobial tuboperitoneal infection probably causes most nongonococcal cases.

Pathogenesis of acute pelvic inflammatory disease: Role of contraception and other risk factors

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

Management of pelvic inflammatory disease (PID) and decisions about contraception are being influenced by reports that oral contraceptives decrease the risk of PID. To evaluate the validity of this association, we have examined published epidemiologic evidence and reviewed relevant information from other disciplines. Current information does not permit the generalization that oral contraceptives protect against all forms of PID. Most studies conducted (1) have been limited to hospitalized women, who represent less than 25% of all PID cases and are likely to have relatively severe forms of the disease, and (2) have failed to distinguish between gonococcal and nongonococcal PID. While oral contraceptives may provide some protection against gonococcal PID, no basis exists for assuming similar protection is provided against chlamydial PID. In fact, epidemiologic and biologic evidence suggests that infection withChlamydia trachomatis, the leading cause of nongonococcal PID, is enhanced by oral contraceptives. We judge the conclusion that oral contraceptives protect against all PID to be premature, and urge caution in its application in health policy and clinical decisions. (JAMA1985;253:2246-2250)
