Abstract

Two men, aged 41 and 28 years, both known to be HIV-positive, contracted multiple sexually-transmitted diseases (STDs) through unprotected anal sexual contact. These included lymphogranuloma venereum (LGV) proctitis and hepatitis C. Recently in The Netherlands and Belgium there has been an outbreak of LGV proctitis in HIV-positive men who have sex with men, caused by Chlamydia trachomatis serovar L2, an STD which up to now has been rare in Europe. Due to information about the epidemic received a few days previously, the LGV proctitis in the second patient could be diagnosed and treated rapidly. The incidence of STDs in men having sex with men is increasing, also in HIV-positive men. STDs with ulcerative lesions, such as LGV, facilitate transmission of other pathogenic micro-organisms, including HIV. This, in combination with high-risk sexual behaviour such as unprotected anal sexual intercourse, will increase the chance of blood-blood contact and hence the chance of contracting multiple STDs concurrently. Hepatitis C is not normally considered as an STD, but ulcerative lesions in one of the partners combined with high-risk sexual behaviour enables the hepatitis C virus to be sexually transmitted.
