Michaela Vyšatová
Lymphogranuloma venereum belongs to the sexually transmitted diseases. The disease is caused by Chlamydia trachomatis serotypes L1, L2 and L3. In the beginning of the 21st century there has been observed a large increase in the incidence of this disease in the world. There is a frequent co-occurrence with other sexually transmitted diseases (HIV, syphilis, gonorrhea, hepatitis C). Predominantly this disease affects homosexuals, in which case the first manifestation of the disease may be proctitis or proctocolitis...

REVIEW
William L Risser, Jan M Risser, Amanda L Risser
In this review, the epidemiology, diagnosis, and treatment of pelvic inflammatory disease (PID) are discussed from a USA perspective and the difficulties that USA adolescents face in recognizing and seeking care for PID and other sexually transmitted infections (STIs) are emphasized. Females aged 15-24 years have the highest incidence of cervical infection with Chlamydia trachomatis and Neisseria gonorrheae, the principal causes of PID. PID is common in this age group. However, the incidence of PID in the USA is not known, because it is not a reportable disease, and because clinicians vary in the criteria used for the diagnosis...

BACKGROUND: To investigate mechanisms underlying our previous observation of a large rise in serum prostate-specific antigen, a marker of prostate pathology, during both sexually transmitted and systemic infections, we measured serum high-sensitivity C-reactive protein (hsCRP), a marker of systemic inflammation, in our previous case-control study of young, male US military members and compared our findings to those for PSA. METHODS: We measured hsCRP before and during infection for 299 chlamydia, 112 gonorrhea, and 59 non-chlamydial, non-gonococcal urethritis (NCNGU) cases; before and after infection for 55 infectious mononucleosis (IM) and 90 other systemic/non-genitourinary cases; and for 220-256 controls...

Our previous pilot study during 2010-2013, based on the IWantTheKit (IWTK) home self-collection program for sexually transmitted infections (STIs), showed that voluntary risk score tool predicted STIs well in female volunteers compared to their male counterparts. Risk score became a required part of the IWTK program in August 2013. We investigated association of IWTK risk score and presence of STI in 592 male participants living in Maryland and Washington DC from August 2013 to April 2015. The risk score quiz includes questions on demographic and sexual risk behavior...

OBJECTIVE: Malays, with majority of the individuals being Muslim, form the largest ethnic group in Southeast Asia. This region is experiencing a rising incidence of HIV infections. Due to circumcision and prohibition of sex outside marriage, being Muslim was argued to be a protective factor against sexually transmitted infections (STI) and Human Immunodeficiency Virus (HIV). However, Malay adolescents were found to be more likely to contract chlamydia and gonorrhea than non-Malay adolescents in Singapore...

Neisseria gonorrhoeae, the causative agent of gonorrhea, has a number of factors known to contribute to pathogenesis; however, a full understanding of these processes and their regulation has proven to be elusive. Post-translational modifications (PTMs) of bacterial proteins are now recognized as one mechanism of protein regulation. In the present study, Western blot analyses, with an anti-acetyl-lysine antibody, indicated that a large number of gonococcal proteins are post-translationally modified. Previous work has shown that Nε-lysine acetylation can occur non-enzymatically with acetyl-phosphate (AcP) as the acetyl donor...

Prenatal screening and treatment for sexually transmitted infections (STIs) can prevent adverse perinatal outcomes. In Guam, the largest of the three U.S. territories in the Pacific, primary and secondary syphilis rates among women increased 473%, from 1.1 to 6.3 per 100,000 during 2009-2013 (1). In 2013, the first congenital syphilis case after no cases since 2008 was reported (1,2). Little is known about STI screening coverage and factors associated with inadequate screening among pregnant women in Guam. This study evaluated the prevalence of screening for syphilis, human immunodeficiency virus (HIV), chlamydia, and gonorrhea, and examined correlates of inadequate screening among pregnant women in Guam...

OBJECTIVE: Sexually transmitted diseases are a significant public health problem. Within the Madrid Autonomous Region, the districts with the highest syphilis and gonorrhea incidences are part of the same Public Health Service (Servicio de Salud Pública del Área 7, SSPA 7). The objective of this study was to identify, by spatial analysis, clusters of syphilis and gonorrhea infections in this SSPA in Madrid. METHODS: All confirmed syphilis and gonorrhea cases registered in SSPA 7 in Madrid were selected...

The function and extracellular location of cell envelope proteins make them attractive candidates for developing vaccines against bacterial diseases, including challenging, drug-resistant pathogens such as Neisseria gonorrhoeae Proteomics-driven reverse vaccinology delivered multiple gonorrhea vaccine candidates; however, the biological functions of many of them remain to be elucidated. Herein, the functions of six gonorrhea vaccine candidates - NGO2121, NGO1985, NGO2054, NGO2111, NGO1205, and NGO1344 - in cell envelope homeostasis were probed using phenotype microarrays with 1,056 conditions and a ΔbamE mutant (Δngo1780) as a reference of perturbed outer membrane integrity...

Little is known about the sexual health of male veterans. This study used nationally representative data from the 2011 to 2013 National Survey of Family Growth to compare sexual behaviors and history of sexually transmitted infections (STIs) between male veterans and nonveterans. The sample included 3,860 men aged 18 to 44 years who reported ever having sex with a man or woman. The key independent variable was veteran status. Sexual behavior outcomes included ≥6 lifetime female partners, ≥10 lifetime partners of either sex, ≥2 past-year partners of either sex, having past-year partners of both sexes, and condom nonuse at last vaginal sex...

BACKGROUND: Early treatment of acute HIV-1 infection (AHI) is beneficial for patients and could reduce onward transmission. However, guidelines on whom to test for AHI with HIV-1 RNA testing are lacking. METHODS: A risk score for possible AHI based on literature and expert opinion - including symptoms associated with AHI and early HIV-1 - was evaluated using data from the Amsterdam Cohort Studies among men who have sex with men (MSM). Subsequently, we optimized the risk score by constructing two multivariable logistic regression models: one including only symptoms and one combining symptoms with known risk factors for HIV-1 seroconversion, using generalized estimating equations...

BACKGROUND: Inequalities in Neisseria gonorrhoeae (gonorrhea) burden by sexual minority status in the United States are difficult to quantify. Sex of sex partner is not routinely collected for reported cases. Population estimates of men who have sex with men (MSM) necessary to calculate case rates have not been available until recently. For these reasons, trends in reported gonorrhea rates among MSM have not been described across multiple jurisdictions. METHODS: We estimated of the number of MSM cases reported in 6 jurisdictions continuously participating in the STD Surveillance Network 2010-2015 based on interviews with a random sample of cases...

Among 485 young black men who have sex with men recruited in Jackson, MS, 90-day anal sexual exposure significantly predicted rectal infection, but 19.4% of rectal infections would have been missed among men denying receptive anal sex. Reports of consistent condom use were associated with lower infection rates only in men reporting insertive anal sex.

BACKGROUND: Rectal sexually transmitted infections (STI) have been associated with human immunodeficiency virus (HIV) diagnosis, but inferring a causal association requires disentangling them from receptive anal intercourse (RAI). METHODS: We conducted a stratified case-control study by frequency matching 4 controls to each case within year using clinical data from men who have sex with men (MSM) attending the Seattle STD Clinic 2001 to 2014. Cases were MSM with a new HIV diagnosis and negative HIV test at 12 months or less...

Hidden populations, such as injecting drug users (IDUs), sex workers (SWs) and men who have sex with men (MSM), are considered at high risk of contracting and transmitting infectious diseases such as AIDS, gonorrhea, syphilis etc. However, public health interventions to such groups are prohibited due to strong privacy concerns and lack of global information, which is a necessity for traditional strategies such as targeted immunization and acquaintance immunization. In this study, we introduce an innovative intervention strategy to be used in combination with a sampling approach that is widely used for hidden populations, Respondent-driven Sampling (RDS)...

Neisseria gonorrhoeae causes the sexually transmitted infection gonorrhea, which is highly prevalent worldwide and has a major impact on reproductive and neonatal health. The "superbug" status of N. gonorrhoeae necessitates development of drugs with different mechanisms of action. Here, we focused on targeting the nitrite reductase AniA, which is a pivotal component of N. gonorrhoeae anaerobic respiration and biofilm formation. Our studies showed that gonococci expressing AniA containing altered catalytic residues, D137A and H280A, failed to grow under anaerobic conditions demonstrating that the nitrite reductase function is essential...
