In a study of human immunodeficiency virus type 1 (HIV-1)-uninfected African prostitutes, 83 (67%) of 124 seroconverted to HIV-1. Oral contraceptive use (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.1-8.6; P less than .03), genital ulcers (mean annual episodes, 1.32 +/- 0.55 in seroconverting women vs. 0.48 +/- 0.21 in seronegative women; P less than .02) and Chlamydia trachomatis infections (OR, 3.6; CI, 1.3-11.0; P less than .02) were associated with increased risk of HIV-1 infection. Condom use reduced the risk of HIV-1 infection (OR, 0.11; CI, 0.05-0.27; P less than .0001). Stepwise logistic regression analysis confirmed independent associations between HIV-1 infection and oral contraceptive use, condom use, genital ulcers, and C. trachomatis. The presence of other sexually transmitted diseases may in part explain the heterosexual HIV-1 epidemic in Africa and may represent important targets for intervention to control HIV-1 infection.

Chlamydia pneumoniae is being recognized as a common cause of respiratory tract infections. Bronchoalveolar lavage specimens from human immunodeficiency virus-infected patients were examined by culture for this pathogen. Of 50 specimens examined, 5 (10%) were positive for C. pneumoniae. Four of these (80%) were also positive for other pathogens frequently implicated as causes of respiratory disease in this patient population. C. pneumoniae may frequently inhabit the respiratory tracts of human immunodeficiency virus-infected individuals.

Neisseria gonorrhoeae strains resistant to treatment with penicillin, tetracycline, and/or spectinomycin are increasing in prevalence in many parts of the world. In Zambia, 52% of N. gonorrhoeae isolates produced beta-lactamase in 1986. Few oral regimens have proven effective for treatment of resistant N. gonorrhoeae. We conducted a prospective, double-blind, randomized clinical trial of 250 mg of ciprofloxacin given orally versus 250 mg of ceftriaxone given intramuscularly for treatment of uncomplicated gonococcal urethritis in adult males. Two hundred men were enrolled and treated. The two groups were comparable in age (27.5 years), prevalence of latent syphilis (14 and 10%), and human immunodeficiency virus infection (32 and 38%). Of 165 patients with cultures positive for N. gonorrhoeae who returned for follow-up, ciprofloxacin cured 83 of 83 (100%), including 26 with penicillinase-producing N. gonorrhoeae (PPNG) and 21 with N. gonorrhoeae with chromosomally mediated resistance to multiple antibiotics (CMRNG), and ceftriaxone cured 81 of 82 (98.7%), including 30 with PPNG and 19 with CMRNG. Both treatment regimens were well tolerated. Chlamydia trachomatis in urethral exudate was found by direct fluorescent-antibody microscopic examination or by culture in 10 (5%) participants. All N. gonorrhoeae isolates were inhibited by ceftriaxone at 0.06 micrograms/ml, except one which was inhibited at 0.125 micrograms/ml, while ciprofloxacin inhibited all isolates at 0.03 micrograms/ml. Ciprofloxacin is a safe and effective therapy for uncomplicated gonococcal urethritis, including that caused by PPNG and CMRNG in human immunodeficiency virus-infected men.

Among the populations of Tonga and Western Samoa, serum antibodies against human immunodeficiency virus or hemorrhagic fever with renal syndrome virus were not detected (0/904 and 0/192). No serum samples were considered to be positive for antibody against human T-cell lymphotropic virus type 1 (0/527). Hepatitis B antigen and antibody were found in 4% (8/192) and 47% (90/192), respectively. Chlamydia trachomatis IgG and C. psittaci IgG antibodies were detected in 39% (75/192) and 47% (91/192), respectively. The possibilities of the spread of human immunodeficiency virus and hemorrhagic fever with renal syndrome virus on the islands when the viruses invade from abroad were discussed.

Artificial insemination with donor semen has become a well established alternative for couples with untreatable male factor infertility. Because of the widespread use of donor insemination, and the increasing awareness and prevalence of sexually transmitted diseases, the American Fertility Society recently redrafted procedural guidelines for the use of donor screening for insemination. Our series of donor screenings is reported to emphasize the necessity of donor evaluations at frequent intervals. From June 1986 through August 1987, 48 healthy male volunteers presented as potential semen donors for our donor program. Each was evaluated with a careful medical history, physical examination and 2 semen analyses for evidence of sexually transmitted disease. On initial evaluation, no donor presented with a positive human immunodeficiency virus antibody, abnormal karyotype, elevated serum glutamic oxaloacetic transaminase, rapid plasma reagent, or positive cultures for Chlamydia or Mycoplasma. One potential donor was excluded because of a positive hepatitis B-core antibody and 1 because of a positive IgM test for cytomegalovirus. At initial examination 3 potential donors had a positive culture for Ureaplasma; all 3 were treated with 3 weeks of tetracycline, and repeat cultures were all negative. Routine followup screening was performed on all donors at 3-month intervals for all sexually transmitted diseases. During this 14-month period cultures converted to positive for Ureaplasma in 4 donors. Furthermore, 1 donor at 6 months contracted gonorrhea. He was treated but no longer used as a donor. Since initiation of the outlined protocol more than 800 inseminations have been performed using fresh semen with no case of sexually transmitted diseases reported from our recipients. We conclude that careful sexual history, and frequent donor and semen evaluation are necessary for prevention of diseases that might be transmitted sexually. If these precautions are strictly observed use of donor semen is safe and effective.

The risk of acquiring a sexually transmitted disease as a result of rape is not known, in part because it is difficult to ascertain whether infections were present before the assault or acquired during it. To investigate this question, we examined female victims of rape within 72 hours of the assault and again at least one week after the assault. Of the 204 girls and women initially examined within 72 hours of the rape, 88 (43 percent) were found to have at least one sexually transmitted disease. These diseases included infections caused by Neisseria gonorrhoeae (6 percent of those tested), cytomegalovirus (8 percent), Chlamydia trachomatis (10 percent), Trichomonas vaginalis (15 percent), herpes simplex virus (2 percent), Treponema pallidum (1 percent), and the human immunodeficiency virus type 1 (HIV-1; 1 percent) and bacterial vaginosis (34 percent). Among the 109 patients (53 percent) who returned for at least one follow-up visit (excluding those who were found to be infected at the first visit or who were treated prophylactically), the incidence of new disease was as follows: gonorrhea, 4 percent (3 of 71); chlamydial infection, 2 percent (1 of 65); trichomoniasis, 12 percent (10 of 81); and bacterial vaginosis, 19 percent (15 of 77). There were no new infections with herpes simplex virus, cytomegalovirus, Trep. pallidum, or HIV-1, but follow-up serologic testing was performed in only 26 percent of the patients. On the basis of our assumptions that most venereal infections present within 72 hours of a rape were preexisting and that new infections identified 1 to 20 weeks later were acquired during the assault, we conclude that the prevalence of preexisting sexually transmitted diseases is high in victims of rape and that they have a lower but substantial additional risk of acquiring such diseases as a result of the assault.

In Sweden, the high numbers of infections with Chlamydia trachomatis and human papillomavirus and the threat of human immunodeficiency virus has been the origin of an ongoing change in the care for people with sexually transmitted diseases (STDs). This is based on the view that traditional STDs, HIV, and abortions are different consequences of the same thing--unprotected intercourse--so prevention of one means prevention of the others and they should always be considered together. There is a growing understanding that epidemiological aspects of STD have to be improved. To attain these goals, new measures are taken at different levels. Central organization committees are created in the counties for the management of STD care. Youth clinics are given better resources. A new kind of department for problems related to sexuality is developed with contributions primarily from gynecology and venereology. The well-established Swedish tradition for sex education is reinforced.

There are certain special considerations in the management of sexually transmitted diseases (STDs) in homosexual men, with the impact of human immunodeficiency virus (HIV) infection on the presentation, diagnosis, and management of certain STDs just becoming apparent recently. Rectal and pharyngeal gonorrhea are usually asymptomatic and also more difficult to treat. The serological diagnosis of syphillis may be unreliable in acquired immunodeficiency syndrome (AIDS) patients, and HIV-seropositive homosexual men may be at risk of accelerated progression to neurosyphilis, despite treatment with benzathine penicillin. Chlamydia trachomatis is infrequently detected in patients with proctitis so therapy should be directed only at culture-positive cases. Herpes simplex is usually severe and persistent in immunosuppressed patients and may be further complicated by the development of acyclovir-resistance. Concurrent HIV infection may be associated with increased infectivity of homosexual chronic hepatitis B carriers, but milder hepatic injury and reduced efficacy of hepatitis B vaccines and immodulatory or antiviral agents. Although there is some concern regarding the possibility of increased risk of anal cancer in homosexual men, conservative management of human papilloma-virus-associated conditions is advised. The carriage of Entamoeba histolytica in this group is rarely associated with any deleterious effects and treatment should be directed only at symptomatic patients in whom other enteric pathogens have been excluded.

During the past two decades, an explosive growth in both the prevalence and types of sexually transmitted diseases has occurred. Up to 55 percent of homosexual men with anorectal complaints have gonorrhea; 80 percent of the patients with syphilis are homosexuals. Chlamydia is found in 15 percent of asymptomatic homosexual men, and up to one third of homosexuals have active anorectal herpes simplex virus. In addition, a host of parasites, bacterial, viral, and protozoan are all rampant in the homosexual population. Furthermore, the global epidemic of AIDS has produced a plethora of colorectal manifestations. Acute cytomegalovirus ileocolitis is the most common indication for emergency abdominal surgery in the homosexual AIDS population. Along with cryptosporidia and isospora, the patient may present to the colorectal surgeon with bloody diarrhea and weight loss before the diagnosis of human immunodeficiency virus (HIV) disease. Other patients may present with colorectal Kaposi's sarcoma or anorectal lymphoma, and consequently will be found to have seropositivity for HIV. However, in addition to these protean manifestations, one third of patients with AIDS consult the colorectal surgeon with either condylomata acuminata, anorectal sepsis, or proctitis before the diagnosis of HIV disease. Although aggressive anorectal surgery is associated with reasonable surgical results in some asymptomatic HIV positive patients, the same procedures in AIDS (symptomatic HIV positive) patients will often be met with disastrous results. It is incumbent upon the surgeon, therefore, to recognize the manifestations of HIV disease and diagnose these conditions accordingly.

From 1 January 1986 to 1 September 1989 124 women presented to the Ambrose King Centre (the department of genitourinary medicine of the London Hospital) alleging rape. Sexually transmitted diseases were found in 36 (29%) women (excluding candidosis and bacterial vaginosis). The commonest organisms detected were Neisseria gonorrhoeae and Trichomonas vaginalis, each being present in 15 patients. Eleven women had genital warts. Chlamydia trachomatis was isolated in six patients, two had herpes simplex virus infection and one patient had pediculosis pubis. Serological evidence of past hepatitis B infection was detected in five women and one patient had antibodies to human immunodeficiency virus. Eighteen of the 36 women (50%) had multiple infections. Six women had abnormal cervical cytology smears, three being suggestive of cervical intraepithelial neoplasia grades II-III. Although it is rarely possible to attribute infection to an assailant, these patients require further counselling, treatment and review. Rape victims are thus a population at risk of having sexually transmitted diseases and screening should be offered.
