Brazilian Protocol for Sexually Transmitted Infections, 2020: infections that cause genital ulcers.

Rev Soc Bras Med Trop 2021 17;54(suppl 1):e2020663. Epub 2021 May 17.

Ministério da Saúde, Secretaria de Vigilância em Saúde, Brasília, DF, Brasil.

Infections that cause genital ulcers are one of the themes comprising the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. The Protocol and Guidelines have been developed based on scientific evidence and validated in discussions with specialists. This article addresses clinical genital ulcer syndrome caused by sexually transmitted infections and its most common etiological agents: Treponema pallidum (syphilis), herpes simplex virus-2 (genital herpes) and herpes simplex virus-1 (perioral herpes), Haemophilus ducreyi (chancroid), Chlamydia trachomatis serotypes L1, L2 and L3 (lymphogranuloma venereum), and Klebsiella granulomatis (donovanosis).

Lymphogranuloma venereum mimicking rectal cancer (T3 N2) and causing a rectovesical fistula.

Int J STD AIDS 2021 May 13:956462420948353. Epub 2021 May 13.

Department of Dermatology and Venereology, Medical University of Graz, Graz, Austria.

We present the case of a 66-year-old bisexual patient suffering from painful bloody defecation, linked to rectal thickening, rectovesical fistula and enlarged lymph nodes in the mesorectal area. The patient was misdiagnosed with rectal cancer (T3 N2) on MRI but the symptoms of the patient were due to lymphogranuloma venereum. After adequate treatment with doxycycline, symptoms faded within days; a control MRI showed complete regression of all pathologic alterations. Read More

Tryptophan Operon Diversity Reveals Evolutionary Trends among Geographically Disparate Chlamydia trachomatis Ocular and Urogenital Strains Affecting Tryptophan Repressor and Synthase Function.

mBio 2021 May 11;12(3). Epub 2021 May 11.

Department of Pediatrics, University of California San Francisco, Oakland, California, USA

The obligate intracellular pathogen () is the leading cause of bacterial sexually transmitted infections and blindness globally. To date, urogenital strains are considered tryptophan prototrophs, utilizing indole for tryptophan synthesis within a closed-conformation tetramer comprised of two α (TrpA)- and two β (TrpB)-subunits. In contrast, ocular strains are auxotrophs due to mutations in TrpA, relying on host tryptophan pools for survival. Read More

Lymphogranuloma venereum as a cause of persistent perianal ulcers.

BMJ Case Rep 2021 Feb 4;14(2). Epub 2021 Feb 4.

Division of HIV, Infectious Diseases and Global Medicine, Department of Medicine, University of California San Francisco, San Francisco, California, USA.

Lymphogranuloma venereum (LGV) has been increasingly reported, and many clinicians are familiar with it as a cause of proctocolitis or inguinal adenopathy. On the other hand, LGV is less commonly considered as a cause of isolated genital ulcerative disease in comparison to other etiologies such as syphilis or herpes simplex. We report a case of persistent perianal ulcerations due to LGV in an HIV-positive patient, confirmed by nucleic acid amplification testing. Read More

L2c Infection in a Porcine Model Produced Urogenital Pathology and Failed to Induce Protective Immune Responses Against Re-Infection.

Front Immunol 2020 26;11:555305. Epub 2020 Oct 26.

Laboratory for Immunology and Animal Biotechnology, Department of Animal Production, Faculty of Bioscience Engineering, Ghent University, Ghent, Belgium.

The current study was designed to evaluate the pathogenesis, pathology and immune response of female genital tract infection with L2c, the most recently discovered lymphogranuloma venereum strain, using a porcine model of sexually transmitted infections. Pigs were mock infected, infected once or infected and re-infected intravaginally, and samples were obtained for chlamydial culture, gross and microscopic pathology, and humoral and cell-mediated immunity. Intravaginal inoculation of pigs with this bacterium resulted in an infection that was confined to the urogenital tract, where inflammation and pathology were caused that resembled what is seen in human infection.
