ABSTRACT

Objective: Considering the lack of data on T. pallidum genotyping in Brazil, we aimed to study its strains and their resistance to macrolides in genital ulcers suggestive of syphilis.Methods: Men with genital ulcers suggestive of syphilis were invited to participate. Samples were collected with a dry cotton swab and immersed in a 0.9% NaCl solution. Detection was done by PCR amplification of 260 bp of the tpp47 gene. The PCR product was analyzed by electrophoresis in a 2% agarose gel containing 0.05% ethidium bromide. Positive PCR samples were analyzed by MLST (sequencing of chromosomal loci TP0136, TP0548, and TP0705). The A2058G and A2059G mutations in the 23S rRNA gene were evaluated by nested PCR. DNA sequencing was analyzed using Bioedit software (Tom Hall, USA). Genotyping was performed using the PubMLST online platform (Grillová scheme). Results: All subjects were residents of Porto Alegre and aged between 19 and 66 years. Of the 43 samples, 32 were positive for PCR for T. pallidum. Thirty strains were available for genotyping and belonged to the SS14-like (73.3%) or Nicholslike (20%) Clonal Complex. Three complete MLST profiles were identified (1.3.1; 9.7.3 and 28.7.3), and a new allele was identified in one sample (approved by pubMLST curators as TP0705-22). Only one sample did not present the 2058 mutation in the 23S rRNA gene.Conclusion: Our study identified genetic diversity in T. pallidum DNA using MLST with allelic variants for TP0136, TP0548, and TP0705, including a new allele. A single sample was characterized as genotypically susceptible to macrolides. All other samples (more than 95%) presented the A2058G mutation in the 23S rRNA gene, which causes resistance to macrolides. Improving understanding of the local epidemiology of T. pallidum with representative samples that allow cofactor analysis is crucial for prevention and care.


Objetivo: Considerando la falta de datos sobre el genotipado de T. pallidum en Brasil, nos propusimos estudiar sus cepas y su resistencia a macrólidos en úlceras genitales sugestivas de sífilis. Métodos: Se invitó a participar a hombres con úlceras genitales sugestivas de sífilis. Las muestras se recogieron con un hisopo de algodón seco y se sumergieron en una solución de NaCl al 0,9%. La detección se realizó mediante amplificación por PCR de 260 pb del gen tpp47. El producto de la PCR se analizó mediante electroforesis en un gel de agarosa al 2% que contenía bromuro de etidio al 0,05%. Las muestras de PCR positivas se analizaron mediante MLST (secuenciación de los loci cromosómicos TP0136, TP0548 y TP0705). Las mutaciones A2058G y A2059G en el gen 23S rRNA se evaluaron mediante PCR anidada. La secuenciación de ADN se analizó utilizando el software Bioedit (Tom Hall, EE. UU.). El genotipado se realizó utilizando la plataforma en línea PubMLST (esquema Grillová). Resultados: Todos los sujetos eran residentes de Porto Alegre y tenían edades comprendidas entre 19 y 66 años. De las 43 muestras, 32 resultaron positivas a la PCR para T. pallidum. Treinta cepas estaban disponibles para el genotipado y pertenecían al Complejo Clonal tipo SS14 (73,3%) o tipo Nichols (20%). Se identificaron tres perfiles MLST completos (1.3.1; 9.7.3 y 28.7.3) y se identificó un nuevo alelo en una muestra (aprobado por los curadores de pubMLST como TP0705-22). Sólo una muestra no presentó la mutación 2058 en el gen 23S rRNA. Conclusión: Nuestro estudio identificó diversidad genética en el ADN de T. pallidum utilizando MLST con variantes alélicas para TP0136, TP0548 y TP0705, incluido un nuevo alelo. Una sola muestra se caracterizó como genotípicamente susceptible a macrólidos. El resto de muestras (más del 95%) presentaron la mutación A2058G en el gen 23S rRNA, que provoca resistencia a los macrólidos. Mejorar la comprensión de la epidemiología local de T. pallidum con muestras representativas que permitan el análisis de cofactores es crucial para la prevención y la atención.

ABSTRACT

OBJECTIVES: Regular quality-assured WGS with antimicrobial resistance (AMR) and epidemiological data of patients is imperative to elucidate the shifting gonorrhoea epidemiology, nationally and internationally. We describe the dynamics of the gonococcal population in 11 cities in Brazil between 2017 and 2020 and elucidate emerging and disappearing gonococcal lineages associated with AMR, compare to Brazilian WGS and AMR data from 2015 to 2016, and explain recent changes in gonococcal AMR and gonorrhoea epidemiology. METHODS: WGS was performed using Illumina NextSeq 550 and genomes of 623 gonococcal isolates were used for downstream analysis. Molecular typing and AMR determinants were obtained and links between genomic lineages and AMR (determined by agar dilution/Etest) examined. RESULTS: Azithromycin resistance (15.6%, 97/623) had substantially increased and was mainly explained by clonal expansions of strains with 23S rRNA C2611T (mostly NG-STAR CC124) and mtr mosaics (mostly NG-STAR CC63, MLST ST9363). Resistance to ceftriaxone and cefixime remained at the same levels as in 2015-16, i.e. at 0% and 0.2% (1/623), respectively. Regarding novel gonorrhoea treatments, no known zoliflodacin-resistance gyrB mutations or gepotidacin-resistance gyrA mutations were found. Genomic lineages and sublineages showed a phylogenomic shift from sublineage A5 to sublineages A1-A4, while isolates within lineage B remained diverse in Brazil. CONCLUSIONS: Azithromycin resistance, mainly caused by 23S rRNA C2611T and mtrD mosaics/semi-mosaics, had substantially increased in Brazil. This mostly low-level azithromycin resistance may threaten the recommended ceftriaxone-azithromycin therapy, but the lack of ceftriaxone resistance is encouraging. Enhanced gonococcal AMR surveillance, including WGS, is imperative in Brazil and other Latin American and Caribbean countries.

ABSTRACT

Objectives: To (i) describe the nationwide antimicrobial susceptibility of Neisseria gonorrhoeae (NG) isolates cultured across Brazil in 2018-20 and compare it with NG antimicrobial resistance data from 2015-16, and (ii) present epidemiological data of the corresponding gonorrhoea patients in 2018-20. Methods: Twelve representative sentinel sites cultured NG isolates from men with urethral discharge. Susceptibility to eight antimicrobials was examined using agar dilution method, according to WHO standards. The consenting participants were invited to provide epidemiological data. Results: In total, 633 NG isolates (one isolate per participant) were analysed, and 449 (70.9%) questionnaires were answered. Heterosexual (68.2%) and homosexual (23.1%) sexual orientations were common, and most prevalent types of unprotected sexual intercourse were vaginal insertive (69.9%), oral giving (56.6%) and anal insertive (47.4%). The levels of in vitro NG resistance to ciprofloxacin, tetracycline, benzylpenicillin, azithromycin, cefixime, gentamicin, spectinomycin and ceftriaxone were 67.3%, 40.0%, 25.7%, 10.6%, 0.3%, 0%, 0% and 0%, respectively. Compliance with the recommended first-line ceftriaxone 500 mg plus azithromycin 1 g therapy was high (90.9%). Conclusions: Compared with 2015-16, ciprofloxacin resistance has remained high and azithromycin and cefixime resistance rates have increased in Brazil. Resistance remained lacking to ceftriaxone, gentamicin and spectinomycin, which all are gonorrhoea treatment options. The increasing azithromycin resistance in Brazil and internationally may threaten the future use of azithromycin in dual regimens for treatment of gonorrhoea. Consequently, continued and enhanced quality-assured surveillance of gonococcal AMR, and ideally also treatment failures and including WGS, is imperative in Brazil and worldwide.

ABSTRACT

Syphilis is a sexually transmitted disease caused by Treponema pallidum. DNA amplification methods have started to be used to facilitate diagnosis at different stages of the disease. The success of such methodologies depends on obtaining DNA from clinical samples in adequate quantity and quality for molecular reactions. There are many DNA extraction kits, but often the molecular analysis process is unfeasible due to its cost and access to imported products. Thus, this study aimed to analyze three methods of extracting DNA from Treponema pallidum from ulcers of patients investigated for syphilis. The three methods, an in house one (sonication) and two commercial ones (LGC, Brazil) and the PureLink Genomic DNA Mini Kit (Thermo Fisher Scientific, USA) were compared to the sequencing of these samples, which were used as a reference. Each method was evaluated based on the detection of T. pallidum by PCR using the tpp47 gene as a target for amplification, DNA quantification and method execution time. When compared to the sequencing, the sensitivity and agreement of the PureLink, sonication and LGC methods to extracted DNA were 100% (K = 1.0), 96.5% (K = 0.96) and 72.4% (K = 0.694), respectively. Specificity was 100% with the three methods. The sonication method was the closest in concentration of DNA to the PureLink method with a similar degree of purity, besides having the lowest cost-benefit ratio. It can be an interesting option for laboratories that work with reduced costs, since it is much more financially viable.

ABSTRACT

OBJECTIVE: To analyze effects of the COVID-19 pandemic on the consumption of personal protective equipment and products (PPEP), as well as the frequency of surgical site infection (SSI) among non-COVID-19 patients submitted to cesarean sections. METHODS: A retrospective study was conducted in a maternity unity of a public teaching hospital which was not part of the reference service for COVID-19 treatment. It compared PPEP consumption and the occurrence of SSI after cesarean sections in monthly periods before and after the occurrence of the first case of COVID-19 in Porto Alegre, state of Rio Grande do Sul, Brazil. Personal protective equipment and products consumption was measured as units of masks, gloves, gowns, and caps, and use of alcohol-based products or soap for hand sanitation as ml/patient/day. The SSI index was calculated as the proportion of cases of SSI over the number of cesarean sections performed monthly during the study period. RESULTS: There was an increase in all measured items of PPEP, with consumption of disposable masks with a median of 1,450 units in the pre-COVID period, and of 2550 in the post-COVID period (a 75.9% increase). A decrease of 49% in SSI was detected, with a median of 1.74 in the pre-COVID period and of 0.89 in the post-COVID period. CONCLUSION: The increase in consumption of PPEP could be a result of safer practices adopted by healthcare workers with the advent of COVID-19, of which the following reduction in the occurrence of SSI could be a direct consequence. Despite the severity of the crisis, one could state that extreme situations can lead to valuable reflections and opportunities for improvement.


OBJETIVO: Analisar os efeitos da pandemia de COVID-19 sobre o consumo de equipamentos e produtos de proteção individual (EPPI), assim como a frequência de infecção de sítio cirúrgico (ISC) em pacientes não infectadas por COVID-19 submetidas a cesarianas. MéTODOS: Foi realizado um estudo retrospectivo em uma maternidade de um hospital público de ensino que não fazia parte do serviço de referência para o tratamento do COVID-19. Foram comparados o consumo de EPPI e a ocorrência de ISC após cesárea nos períodos mensais antes e após a ocorrência do primeiro caso de COVID-19 em Porto Alegre, RS, Brasil. O consumo de EPPI foi medido em unidades de máscaras, luvas, aventais e gorros, e o uso de produtos à base de álcool ou de sabonete para higienização das mãos em ml/paciente/dia. O índice SSI foi calculado como a proporção de casos de ISC sobre o número de cesarianas realizadas mensalmente durante o período do estudo. RESULTADOS: Houve aumento em todos os itens medidos do EPPI, com o consumo de máscaras descartáveis apresentando uma mediana de 1.450 no período pré-COVID e de 2550 no período pós-COVID (aumento de 75,9%). Detectou-se também diminuição de ISC, com medianas de 1,74 no período pré-COVID e de 0,89 no período pós-COVID, com redução de 49% no valor da mediana. CONCLUSãO: O aumento do consumo de EPPI pode ser resultado de práticas mais seguras adotadas pelos profissionais de saúde com o advento do COVID-19, do qual a redução na ocorrência de ISC pode ser uma consequência direta. Apesar da gravidade da crise, pode-se afirmar que situações extremas podem gerar reflexões valiosas e oportunidades de melhorias.

ABSTRACT

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). Epidemiological and clinical aspects of these infections and guidelines for their diagnosis and treatment are presented, including strategies for surveillance, prevention, and control actions to support health managers and professionals in the qualification of care. Approximately 70% of the genital ulcers attended in specialized clinics are due to sexually transmitted infections, particularly in adolescents and young adults.

ABSTRACT

Abstract We present the case of an HIV-negative man with asymptomatic penile erythematoviolaceous papules associated with similar slightly verrucous papules in the interdigital space of the right foot. A biopsy of the penile lesion confirmed Kaposi's sarcoma. No other causes of immunosuppression were observed. Penile lesions of KS are rare in HIV-negative individuals but it should also be considered in the differential diagnosis. Careful follow-up is recommended.

ABSTRACT

OBJECTIVES: Neisseria gonorrhoeae antimicrobial resistance (AMR) surveillance is imperative internationally, but only eight (22.9%) countries in the WHO Region of the Americas reported complete AMR data to the WHO Global Gonococcal Antimicrobial Surveillance Program (WHO GASP) in 2016. Genomic studies are ideal for enhanced understanding of gonococcal populations, including the spread of AMR strains. To elucidate the circulating gonococcal lineages/sublineages, including their AMR determinants, and the baseline genomic diversity among gonococcal strains in Brazil, we conducted WGS on 548 isolates obtained in 2015-16 across all five macroregions in Brazil. METHODS: A total of 548 gonococcal isolates cultured across Brazil in 2015-16 were genome sequenced. AMR was determined using agar dilution and/or Etest. Genome sequences of isolates from Argentina (n = 158) and the 2016 WHO reference strains (n = 14) were included in the analysis. RESULTS: We found 302, 68 and 214 different NG-MAST, MLST and NG-STAR STs, respectively. The phylogenomic analysis identified one main antimicrobial-susceptible lineage and one AMR lineage, which was divided into two sublineages with different AMR profiles. Determination of NG-STAR networks of clonal complexes was shown as a new and valuable molecular epidemiological analysis. Several novel mosaic mtrD (and mtrR and mtrE) variants associated with azithromycin resistance were identified. CONCLUSIONS: We describe the first genomic baseline data to support the Brazilian GASP. The high prevalence of resistance to ciprofloxacin, tetracycline and benzylpenicillin, and the high number of isolates with mosaic penA and azithromycin resistance mutations, should prompt continued and strengthened AMR surveillance, including WGS, of N. gonorrhoeae in Brazil.

ABSTRACT

We present a case of a penile lesion with a clinical appearance similar to Mondor penile disease (thrombosis of the dorsal vein of the penis) or penile sclerosing lymphangitis. Laboratory evaluation, however, showed a solid lesion, with no vascular component to Doppler ultrasonography and no treponema to immunohistochemistry. Histological and serological tests were compatible with secondary syphilis. The authors reinforce the need for the inclusion of syphilis in the differential diagnosis of penile cord injuries.

ABSTRACT

Abstract Gestational syphilis is a prevalent disease in Brazil and other low and medium income countries. Desensitization to penicillin is recommended for pregnant women with syphilis who are allergic to β-lactams. This is a descriptive study utilizing outpatient medical records from 2011 to 2015 from a mother and child hospital that is part of the national healthcare system in the South of Brazil, which performs an average of 3,600 birth assistances per year. All cases of pregnant women with syphilis and presumptive diagnosis of β-lactam allergy during the study period were included. The patients referred for desensitization originated from the hospital prenatal care service, as well as from municipal/state antenatal care services. Oral desensitization was performed in the obstetric emergency room, and adult and pediatric intensive care units were available at all times. Ten patients underwent desensitization during the period of study. Personal history of urticaria was the most common reaction that demanded desensitization. All patients tolerated the procedure well, and showed no adverse reactions.We report a successful program of oral desensitization. None of the patients presented adverse reactions or complications, a fact that corroborates the feasibility and safety of the desensitization protocol. Oral administration of penicillin comes at a low cost, and optimizes the use of time and resources.

ABSTRACT

Gestational syphilis is a prevalent disease in Brazil and other low and medium income countries. Desensitization to penicillin is recommended for pregnant women with syphilis who are allergic to ß-lactams. This is a descriptive study utilizing outpatient medical records from 2011 to 2015 from a mother and child hospital that is part of the national healthcare system in the South of Brazil, which performs an average of 3,600 birth assistances per year. All cases of pregnant women with syphilis and presumptive diagnosis of ß-lactam allergy during the study period were included. The patients referred for desensitization originated from the hospital prenatal care service, as well as from municipal/state antenatal care services. Oral desensitization was performed in the obstetric emergency room, and adult and pediatric intensive care units were available at all times. Ten patients underwent desensitization during the period of study. Personal history of urticaria was the most common reaction that demanded desensitization. All patients tolerated the procedure well, and showed no adverse reactions. We report a successful program of oral desensitization. None of the patients presented adverse reactions or complications, a fact that corroborates the feasibility and safety of the desensitization protocol. Oral administration of penicillin comes at a low cost, and optimizes the use of time and resources.
