Individuals who are seropositive for the human immunodeficiency virus (HIV) frequently have disorders affecting the anorectum, yet little has been reported on this subject. We reviewed our initial experience with patients with HIV referred to the Division of Colon and Rectal Surgery. Forty patients (age range, 19-45 years; mean, 32.2 years) were seen between 1985 and 1989. The mean duration of symptoms was six months (range, one week to six years). In 25 patients (63 percent), more than one anorectal condition was identified. Condylomata were seen in 21 patients (52 percent), and in 11 these were associated with other pathologies. Fistulas and/or abscesses were identified in 15 patients (37 percent). Three had a "watering-can perineum," all without any identifiable predisposing factors. Nineteen patients had symptomatic hemorrhoids (seven), fissures (17), and/or perianal herpes infections (five), usually in combination with other lesions (89 percent). Three individuals developed neoplastic processes. Rectal disease was discovered in addition in nine patients. This included nonspecific proctitis in four, a rectal mass in four (polyps, two; rectal diverticulum, one; and Kaposi's sarcoma, one), and a nonspecific rectal ulcer in one. Four patients had other symptoms, including diarrhea, incontinence, soiling, frequency, and/or urgency, always in combination with other anal disorders. Seventy-one operative procedures were performed in 31 patients (78 percent). Only six (8 percent) of these were for diagnosis and biopsy alone. Mean follow-up was 15.5 months in the 23 patients followed for greater than one month. Only 6 of 23 (26 percent) had resolution of their problem. Nine (39 percent) developed new perianal conditions. Anorectal disorders are often seen in patients infected with HIV. They may be aggressive, cause significant morbidity, and be difficult to resolve.

In a cross-sectional study of 140 homosexual men attending a sexually transmissible diseases clinic, the association between the presence of antibody to the human immunodeficiency virus (HIV) and the presence of proctitis, as determined by histologic examination, as well as part or present exposure to other pathogens and details of sexual practices was analyzed. Significant associations with HIV seropositivity were found with the number of lifetime partners, positive treponemal serology, and evidence of previous infection with herpes simplex virus. However the major and unique finding was the strong and independent association between proctitis diagnosed by histologic criteria and seropositivity for HIV. Whether this is cause or effect awaits further elucidation.

In a study of bowel parasites in 128 Australian homosexual men attending a sexually transmitted diseases (STD) clinic, Entamoeba histolytica was detected in 37%, Giardia intestinalis in 3% and at least one protozoan in 81% of the group. There was no evidence of pathogenicity of E. histolytica, nor was there any association between the detection of E. histolytica and sexual practices, gastrointestinal symptoms, proctitis, human immunodeficiency virus antibody result or T-cell subset values. However it was noted that those subjects with an elevated IgM greater than 4 g/l were more likely to harbour E. histolytica trophozoites than those with a level below 4 g/l (OR 6.54, 95% CI 1.3-32.8). Travel to South-East Asia, India, China, Africa, South America or the Pacific islands in the previous 3 years emerged also as an independent factor (OR 2.70, 95% CI 1.12-6.53) associated with detection of E. histolytica.

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.

Twenty-seven men with laboratory-confirmed lymphogranuloma venereum (LGV) were identified among 211 patients tested for LGV or chancroid during a 6-y period. The patients with LGV ranged in age from 17 to 73 y; most were from countries other than France. Twenty-five sought care because of inguinal adenopathy (with spontaneous draining fistulae in two patients) and two because of proctitis. Chlamydia trachomatis was isolated from nine patients; all isolates were the LGV biovar as demonstrated by biologic characterization and monoclonal antibody reactivity. In patients without isolation of C. trachomatis, the diagnosis was based on chlamydial complement fixation antibody titers greater than or equal to 1:32 (mean titer, 1:128). Genital herpes was an associated diagnosis in one patient and syphilis in two patients. Serologic evidence of exposure to human immunodeficiency virus (HIV) type 1 was present in five patients and to HIV-2 in one patient.

We studied 388 homosexual or bisexual men from the Baltimore-Washington area to define the spectrum of enteric pathogen carriage in a population at high risk for "gay bowel syndrome" in association with human immunodeficiency virus infection. Seventy-seven patients with acquired immunodeficiency syndrome, 68 gay men with symptoms of acute diarrhea or proctitis, and 243 gay men without gastrointestinal symptoms and participating in a natural history study of human immunodeficiency virus infection were selected for study. Approximately 12% of the asymptomatic men harbored at least one enteric pathogen; the most frequently recovered were Chlamydia trachomatis, herpes simplex virus, and Giardia lamblia. Men carrying a pathogen were more likely to be human immunodeficiency virus seropositive (48%) than men without a pathogen (25%) (p = 0.018), more likely to have fewer T helper cells (p = 0.015), and more likely to have a mucopurulent exudate (p = 0.014). We recovered an agent of enteric disease from 68% of gay men presenting with diarrhea or proctitis. Campylobacter species, herpes simplex virus, Neisseria gonorrhoeae, C. trachomatis, G. lamblia, and Shigella species were identified most frequently. The most common pathogen associated with diarrhea in acquired immunodeficiency syndrome was Cryptosporidium (16% of 49 cases). Other agents identified were Clostridium difficile, Vibrio parahemolyticus, Campylobacter species, G. lamblia, Isospora, and cytomegalovirus. Approximately half of the identifiable etiologic agents of diarrhea in acquired immunodeficiency syndrome patients were treatable with antibiotics, but these agents required special culture procedures for detection.

A heterosexual woman with cytomegalovirus (CMV) proctitis after anal intercourse is presented. Whereas CMV infection typically occurs in immunosuppressed patients, including patients with acquired immune deficiency syndrome (AIDS), this patient has no evidence of immunodeficiency, and is human immunodeficiency virus (HIV) negative during 8 months of follow-up since onset of proctitis. A review of the literature reveals no other report of sexually transmitted CMV proctitis in an immunocompetent woman after anal intercourse.

Herpes viruses (HSV, CMV, VZ) are very frequent in AIDS patients and often exist in a chronic or progressive form. Clinically evident CMV retinitis occurs in approximately 10 per cent of AIDS patients but can be effectively treated with a new nucleoside analogue DHPG (Gancyclovir). Perianal ulcers, proctitis, and other clinical syndromes caused by HSV can be effectively treated with acyclovir (ACV) and HSV recurrences can be prevented by daily administration of ACV. Zoster in a young adult may be the first indication of immunodeficiency due to HIV. Because VZV is less susceptible to ACV than HSV, intravenous ACV or high-dose oral therapy is required to achieve inhibitory blood levels.

A case of proctitis and fatal septicemia caused by Plesiomonas shigelloides in a 42-year-old bisexual male is reported. The medical history of the patient was significant for an aortic valve replacement 3 years before but was otherwise unremarkable. A serum specimen obtained at autopsy was negative for antibody to human immunodeficiency virus by Western blot (immunoblot) analysis. P. shigelloides isolated from blood was susceptible to all antibiotics tested, agglutinated in Shigella group D antiserum, possessed a greater than 100-megadalton plasmid, and was noninvasive in a HeLa cell invasion assay. The previous reports of Plesiomonas bacteremic infections are reviewed, and possible pathogenic mechanisms are discussed.
