Ninety patients seroreactive to HIV-1 were studied in order to describe the clinical manifestations of other sexually transmitted diseases as well as the demographic and behaviour factors associated to the HIV-1 infected and AIDS patients. The majority (83.3%) were males with a mean age of 31.4 years of age (range between 18 and 60 years) and a monthly family income for 79.5% of less than five mininum wages. At least one type of ilicit drug was used by 51.1% and 20.7% were intravenous drug users. Among them, 94.4% referred to a previous episode of a sexually transmitted disease. The subjects revealed that 41.6% were bisexuals, 38.2% heterosexuals and 20.2% were homosexuals. Approximately 51.1% of the bisexual subjects were intravenous drugs users and all referred to have had ano-rectal intercourse and were all positive for the presence of antibodies to Chlamydia. The mean age of the first sexual relation with penetration and the first episode of sexually transmitted disease were at 14.7% and 20.6% years of age, respectively. The vast majority (95.5%) of the subjects experienced multiple sexual partners before the knowledge of their HIV-l positive serology status. Among the 73.3% that referred a previous episode of sexually transmitted diseases, 82.2% also referred urethral discharge, syphilis and herpes simplex. At physical examination, 36.6% (33/90) presented urethral, anal and vaginal discharge and genital lesions such as discharges (51.1%), vesicles (18.1%), warts (18.1%), lymphadenopathy (18.1%), ulcers (12.1%) and papules (6%). Reaction to the VDRL and antibodies to Chlamydia were present in 13.7% and 96.4%, respectively. The vast majority referred ano-retal intercourse and previous episodes of sexually transmitted diseases.

Serological Evidence of HTLV-I and HTLV-II Coinfections in HIV-1 Positive Patients in Belém, State of Pará, Brazil
(1998-06) VALLINOTO, Antonio Carlos Rosário; AZEVEDO, Vânia Nakauth; SANTOS, Domingos Ezenildo Matos dos; MARTINS, Sandra Suely Caniceiro; MESQUITA, Francisco Carlos Lopes de; HALL, William W.; ISHAK, Marluísa de Oliveira Guimarães; ISHAK, Ricardo
The occurrence of HTLV-I/II and HIV-1 coinfections have been shown to be frequent, probably in consequence of their similar modes of transmission. This paper presents the prevalence of coinfection of HTLV among HIV-1 infected and AIDS patients in Belém, State of Pará, Brazil. A group of 149 patients attending the AIDS Reference Unit of the State Department of Health was tested for the presence of antibodies to HTLV-I/II using an enzyme immunoassay and the positive reactions were confirmed with a Western blot that discriminates between HTLV-I and HTLV-II infections. Four patients (2.7%) were positive to HTLV-I, seven (4.7%) to HTLV-II and one (0.7%) showed an indeterminate pattern of reaction. The present results show for the first time in Belém not only the occurrence of HTLV-II/HIV-1 coinfections but also a higher prevalence of HTLV-II in relation to HTLV-I. Furthermore, it also enlarges the geographical limits of the endemic area for HTLV-II in the Amazon region of Brazil.
