ABSTRACT
Resumen El linfogranuloma venéreo es una infección de trans misión sexual (ITS) causada por las serovariedades L1, L2 y L3 de Chlamydia trachomatis. Una forma rara de presen tación del estadio primario es la linfangitis localizada en pene, con la formación de uno o más nódulos linfáticos tensos clásicamente llamados "bubonódulos" (bubón pe queño). Presentamos el caso de un paciente HIV positivo con conductas de riesgo para ITS con nódulos peneanos como manifestación de linfogranuloma venéreo.
Abstract Lymphogranuloma venereum is a sexually trans mitted disease caused by L1, L2 and L3 serovars of Chlamydia trachomatis. A rare clinical presentation of the primary stage is lymphangitis of the penis, with the appearance of one or more tense lymph nodes classically called "buboes". We report the case of an HIV-positive patient with sexually transmitted disease risk behaviors with penile nodules as a manifestation of lymphogranuloma venereum.

Una forma rara de presentación del estadio primario es la linfangitis localizada en pene, con la formación de uno o más nódulos linfáticos tensos clásicamente llamados "bubonódulos" (bubón pequeño). Presentamos el caso de un paciente HIV positivo con conductas de riesgo para ITS con nódulos peneanos como manifestación de linfogranuloma venéreo.

BACKGROUND: Sexually transmitted infections (STIs) are prevalent throughout the world and impose a significant burden on individual health and public health systems. Missed diagnosis and late treatment of STIs can lead to serious complications such as infertility and cervical cancer. Although sexually transmitted co-infections are common, most commercial assays target one or a few STIs. The HPV-STI ChapterDx Next Generation Sequencing (NGS) assay detects and quantifies 29 HPVs and 14 other STIs in a single-tube and single-step PCR reaction and can be applied to tens to thousands of samples in a single sequencing run. METHODS: A cohort of 274 samples, previously analyzed by conventional cytology/histology and Roche cobas HPV Test, were analyzed by ChapterDx HPV-STI NGS assay for detection of 43 HPV and STI. A set of 43 synthetic control DNA fragments for 43 HPV and STI were developed to evaluate the limit of detection, specificity, and sensitivity of ChapterDx HPV-STI NGS assay. RESULTS: The assay was evaluated in this study, and the limit of detection was 100% at 50 copies for all targets, and 100%, 96%, 88% at 20 copies for 34, 8, and 1 target, respectively. The performance of this assay has been compared to Roche cobas HPV test, showing an overall agreement of 97.5% for hr-HPV, and 98.5% for both, HPV16 and HPV18. The assay also detected all HPV-infected CIN2/3 with 100% agreement with Roche cobas HPV results. Moreover, several co-infections with non-HPV STIs, such as C. trachomatis, T. vaginalis, M. genitalium, and HSV2 were identified. CONCLUSIONS: The ChapterDx HPV-STI NGS assay is a user-friendly, easy to automate and cost-efficient assay, which provides accurate and comprehensive results for a wide spectrum of HPVs and STIs.
ABSTRACT
El linfogranuloma venéreo (LGV) es una enfermedad de transmisión sexual (ETS) poco frecuente causada por los serotipos L1, L2 y L3 de Chlamydia trachomatis.Desde hace más de una década se produjo un aumento de la incidencia de proctitis por LGV casi exclusivamente en hombres que tienen sexo con hombres con prácticas sexuales de riesgo para ETS.Se presentan cuatro casos con LGV rectal
Lymphogranuloma venereum is a rare sexually transmitted infection (STI) caused by serotypes L1, L2 and L3 of Chlamydia trachomatis.For over a decade, there has been a considerable increase in the incidence of LGV proctitis in almost exclusively men who have sex with men with STI risk behaviors.Four cases of rectal LGV are reported

BACKGROUND: The emergence of Neisseria gonorrhoeae strains with decreased susceptibility to cephalosporins represents a major concern globally. The aim of this study was to examine the phenotypic and molecular characteristics of N. gonorrhoeae isolates with decreased susceptibility to ceftriaxone and cefixime in Argentina. METHODS: A total of 1987 isolates were collected during 2009 and 2013. The susceptibility to penicillin G, tetracycline, ciprofloxacin, cefixime, ceftriaxone, and azithromycin was determined using the agar dilution method. The major extended-spectrum cephalosporin resistance determinants (penA, mtrR, and porB1b) were sequenced in 42 N. gonorrhoeae isolates that showed decreased susceptibility to ceftriaxone (minimum inhibitory concentration [MIC], 0.06-0.125 mg/L) and cefixime (MIC, 0.125-0.25 mg/L). Genotyping by N. gonorrhoeae multiantigen sequence typing (NG-MAST) was performed. RESULTS: Between 2009 and 2013, there was a shift in the modal MICs for ceftriaxone. Among the 42 isolates exhibiting decreased susceptibility to ceftriaxone and cefixime, 95.2% were resistant to penicillin G, 95.2% to tetracycline, 97.6% to ciprofloxacin, and 33.3% to azithromycin. Thirty-five (83.3%) of the 42 isolates had a mosaic penA allele XXXIV, which has been previously associated with resistance to ceftriaxone and cefixime as well as treatment failures. The isolates that contained the mosaic penicillin-binding protein 2 (PBP2) XXXIV were associated with NG-MAST ST1407 or closely related genotypes. CONCLUSIONS: In Argentina, N. gonorrhoeae isolates with decreased susceptibility to cefixime and ceftriaxone have now emerged, mostly due to the introduction of the internationally spread multidrug-resistant NG-MAST ST1407.
