Sexually transmitted diseases and enteric infections in the male homosexual population.
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.
