Clinical and epidemiological features of mpox in a Brazilian reference center for HIV and sexually transmitted infections: A cross-sectional study.

Background: The 2022 mpox outbreak has affected disproportionately people living with HIV (PLWH) and pre-exposure prophylaxis (PrEP) users.

Methods: We conducted a cross-sectional study to evaluate factors associated with laboratory diagnosis of mpox among suspected cases, and access differences between PrEP users and PLWH with confirmed diagnostic.

Results: 394 mpox suspected cases were analyzed, 309 (78.

Anorectal gonorrhoea and chlamydia among transgender women in Brazil: prevalence and assessment of performance and cost of anorectal infection detection and management approaches.

Objectives: We aimed to determine the prevalence of anorectal (NG) and (CT) among transgender women in Brazil, and to assess the performance and costs of various approaches for the diagnosis and management of anorectal NG/CT.

Methods: TransOdara was a multicentric, cross-sectional STI prevalence study among 1317 transgender women conducted in five capital cities representing all Brazilian regions. Participants aged 18 years were recruited using respondent-driven sampling (RDS), completed an interviewer-led questionnaire, offered an optional physical examination and given choice between self-collected or provider-collected samples for NG/CT testing.

Temporal evolution of antimicrobial resistance among Neisseria gonorrhoeae clinical isolates in the most populated South American Metropolitan Region.

A total of 124 Neisseria gonorrhoeae isolates recovered during a 12-year period (2003-2015) from outpatients assisted at Centro de Referência e Treinamento DST/AIDS-CRT of São Paulo city, Brazil, were analysed. The following resistance rates were observed: penicillin-59.6%, ciprofloxacin-15.

HPV-related external genital lesions among men residing in Brazil.

The aims of this study were to determine the incidence of external genital lesions (EGLs), specifically histologically confirmed condyloma (genital warts) and Penile Intraepithelial Neoplasia (PeIN), and genital HPV infection progression to EGLs among healthy men aged 18-73 residing in Brazil. Subjects included 1118 men enrolled in the HPV Infection in Men (HIM) study between July 2005 and June 2009. At each visit, EGLs were biopsied and subjected to pathological evaluation.

Association of Chlamydia trachomatis infection and herpes simplex virus type 2 serostatus with genital human papillomavirus infection in men: the HPV in men study.

Background: Studies in women indicate that some sexually transmitted infections promote human papillomavirus (HPV) persistence and carcinogenesis. Little is known about this association in men; therefore, we assessed whether Chlamydia trachomatis (CT) infection and herpes simplex virus type 2 (HSV-2) serostatus are associated with genital HPV prevalence, an early event in HPV-related pathogenesis.

Methods: Genital exfoliated cells, first-void urine, and blood from 3971 men recruited in the United States, Mexico, and Brazil were tested for HPV, CT, and HSV-2 antibodies, respectively.
