In 2023, a second wave of the global mpox epidemic, which is mainly affecting men who have sex with men (MSM), was observed in some countries. Herein, we benefited from a large viral sequence sampling (76/121; 63%) and vast epidemiological data to characterise the re-emergence and circulation of the Monkeypox virus (MPXV) in Portugal during 2023. We also modelled transmission and forecasted public health scenarios through a compartmental susceptible-exposed-infectious-recovered (SEIR) model. Our results suggest that the 2023 mpox wave in Portugal resulted from limited introduction(s) of MPXV belonging to C.1.1 sublineage, hypothetically from Asia, followed by sustained viral transmission and potential exportation to other countries. We estimated that the contribution of the MSM high sexual activity group to mpox transmission was 120 (95% CrI: 30–3553) times higher than that of the low sexual activity group. However, among the high sexual activity group, vaccinated individuals likely contributed approximately eight times less [0.123 (95% CrI: 0.068–0.208)] than the unvaccinated ones. Vaccination was also linked to potential reduced disease severity, with a Mpox Severity Score of 6.0 in the vaccinated group compared to 7.0 in unvaccinated individuals. Scenario analysis indicated that transmission is highly sensitive to sexual behaviour, projecting that a slight increase in the MSM sub-population with high sexual activity can trigger new mpox waves. This study strongly supports that continued vaccination, targeted awareness among risk groups and routine genomic epidemiology is needed to anticipate and respond to novel MPXV threats (e.g. global dissemination of clade I viruses).

A infeção por Chlamydia trachomatis é a infeção bacteriana sexualmente transmissível mais frequente a nível global. A sua abordagem diagnóstica é desafiante pela existência de um grande número de portadores assintomáticos, e requer uma disponibilização apropriada de testes laboratoriais à população em risco. Em Portugal, a incidência da infeção tem crescido de forma consistente nos últimos anos, pelo que se impõe a necessidade de cuidados redobrados na identificação de casos, rastreio de contactos sexuais e aplicação de medidas terapêuticas eficazes. As presentes recomendações resultam da adaptação à realidade portuguesa dos consensos internacionais em termos de diagnóstico e terapêutica da infeção por Chlamydia trachomatis, e foram formuladas com o objetivo de uniformizar a gestão clínica e laboratorial dos casos sintomáticos e portadores não sintomáticos da infeção em Portugal à luz dos conhecimentos atuais.

Objective: Genital herpes (GH) is one of the most common sexual transmitted infections. Herpes simplex virus type 1 (HSV-1) genital infections have been increasing, with a shift toward its predominance in many developed countries. The aim of this study was to characterize the population with GH diagnosed in Centro Hospitalar Universitário de Lisboa Central, Lisbon, Portugal. Methods: A retrospective analysis of all laboratory-confirmed diagnosis of GH between 2017 and 2021 was conducted. The diagnosis was established by real-time polymerase chain reaction, in samples collected by swabbing suspicious mucocutaneous lesions. Medical records of included patients were reviewed and data of interest analyzed. Results: During the studied period, a total of 239 patients were diagnosed with GH, from which 76.6% (n = 183) were caused by HSV type 2 (HSV-2). Most patients were men (68%; n = 163), with a mean age of 35.7 years. Compared to the group diagnosed with HSV-2, the mean age was significantly lower in the HSV-1 group (28.6 years vs. 37.9; p < 0.001) and the proportion of patients with first clinical manifestations of GH was significantly higher in the latest (67.8% vs. 30%; p

Abstract Background Infection by the monkeypox virus classically causes a cutaneous rash that is preceded by fever and lymph node swelling, as well as other nonspecific systemic symptoms. A recent outbreak occurred and spread in Europe and other regions, especially among patients who declare themselves as men who have sex with men. Current reports have shown that cutaneous lesions may be limited to the anogenital area. We report on a case of proctitis caused by monkeypox virus, without visible typical lesions of this virus. Case presentation A 29-year-old Caucasian male presented with a monkeypox virus proctitis that recurred after treatment for a documented Neisseria gonorrhoeae and Chlamydia trachomatis coinfection, likely acquired at the same time. The proctitis was preceded by fever and a swollen inguinal lymph node, and was associated with a hemorrhoid. The monkeypox virus polymerase chain reaction of a rectal swab documented high viral loads, although no typical lesion was visible. After resolution of the rectitis, the patient developed a single dermatome herpes zoster, despite the absence of usual risk factors. The patient evolved well without further specific treatment. Conclusion This case shows that monkeypox virus can be responsible for proctitis, without any typical lesion, along with the important rectal shedding of the virus. It raises the concern of contagion during anal intercourse through body fluids and gives further credit that monkeypox virus can be a sexually transmitted infection. This should prompt routine rectal screening in patients with proctitis accompanied by fever and swollen lymph nodes, and in patients who have a history of unprotected receptive anal sex, even in presence of other sexually transmitted infections, and especially during a monkeypox virus outbreak. The potential link between monkeypox virus infection and shingles warrants further investigations.

O risco infecioso associado a terapêutica biológica é cada vez mais estudado e conhecido, existindo estratégias de rastreio e profilaxia bem estabelecidas. O mesmo não se verifica na utilização de corticoide sistémico nem dos tradicionais modificadores de doença autoimune, de que são exemplo o metotrexato e a ciclosporina, apesar de usados há largos anos. A dose e tempo de terapêutica com corticoide sistémico relacionam-se com a ocorrência de infeção oportunista. Doses superiores a 5 mg/dia associam-se a infeção bacteriana, superiores a 10 mg/dia a reativação de infeção por vírus herpes zoster (VHZ), e superiores a 15 mg/dia ou por mais de 2 a 4 semanas a reativação de tuberculose latente, o que implica rastreio e aplicação de quimioprofilaxia de forma adequada. O corticoide sistémico surge ainda como dos principais fatores de risco para o desenvolvimento de pneumocistose no doente não-VIH e doses prolongadas (por mais de 4 semanas) podem levar a reativação de infeção por vírus da hepatite B (VHB) e justificar a profilaxia com tenofovir disoproxil fumarato ou entecavir. Foram ainda descritos casos de estrongiloidíase complicada de síndrome de hiperinfeção em doentes sob corticoide. O grau de imunossupressão conferido pode contraindicar a realização de vacinas vivas atenuadas. O metotrexato e ciclosporina comportam baixo risco infecioso quando utilizados em monoterapia, sendo a vigilância de sintomas a principal estratégia preventiva. Não obstante, ambos são imunomoduladores, contraindicam a realização de vacinas vivas atenuadas e associam-se a risco de infeção bacteriana e reativação de infeção por VHZ, no caso da ciclosporina, ou reativação de infeção por VHZ e VHB no caso do metotrexato, sobretudo se administrado em dose >0,4 mg/kg/semana. Ambos se associam a evolução para tuberculose ativa quando em associação terapêutica com outros imunossupressores. Compreender e estudar o risco de infeção na utilização de terapêutica imunossupressora permite a sua aplicação de forma mais informada e segura.

Introduction: Recent studies worldwide reveal a significant prevalence of extragenital infections by Neisseria gonorrhoeae among men who have sex with men. We aimed to analyse the frequency and characteristics of extragenital gonococcal infections diagnosed in men who have sex with men in a walk-in Sexually Transmitted Infection clinic in Lisbon, Portugal. Material and Methods: We conducted a cross-sectional, retrospective study of the anorectal and/or oropharyngeal Neisseria gonorrhoeae infections in men who have sex with men, diagnosed in our Sexually Transmitted Infection clinic between January 2014 and December 2016. Results: We found extragenital infection in 87 cases of gonorrhoea identified in men who have sex with men in this period, including: 49 cases of anorectal disease, 9 of oropharyngeal disease, 13 cases of infection at both extragenital sites, and 16 of simultaneous extragenital and urogenital gonorrhoea. Patients’ ages ranged from 17 to 64 years (median: 28 years). Forty-seven (54%) of the patients did not present with any extragenital symptoms. Thirty (35%) were human immunodeficiency virus-1-positive. Discussion: Since most extragenital Neisseria gonorrhoeae infections are asymptomatic, they may be missed and go untreated unless actively investigated. Current international guidelines recommend the screening of gonorrhoea at extragenital sites in men who have sex with men because anorectal and oropharyngeal infections constitute a potential disease reservoir, and may facilitate transmission and/or acquisition of human immunodeficiency virus infection. Conclusion: Our results highlight the relevance of testing men who have sex with men for Neisseria gonorrhoeae at extragenital sites, regardless of the existence of local complaints. The implementation of adequate screening programmes in Portugal should be considered. We also reinforce the need to raise awareness in the population regarding the adoption of prophylactic measures against transmission of sexually transmitted infections during anal and/or oral sexual exposure.

Syphilis is an old disease and a major public health concern, which is re-emerging in the western world. Atypical syphi- litic presentations can be challenging to diagnose. We present a 23-year-old, HIV-positive man who has sex with men who presented with a 2-week history of an asymptomatic lesion on the glans. Previous topical and systemic treatments proved unsuccessful. Physical examination demonstrated a slightly indurated, ill-defined erythematous plaque over most of the glans. Enlarged, non-tender, bilateral inguinal lymph nodes were palpable. Serological tests revealed a fourfold increase in the VDRL titre (1:8, previously 1:2). A diagnosis of syphilitic balanitis of Follmann was made and complete resolution was achieved with an intramuscular single dose of benzathine penicillin 2.4 MU. Syphilitic balanitis of Follmann represents an uncommon manifestation of primary syphilis, with less than 100 cases reported. Untrea- ted, it will resolve spontaneously, but the patient will remain highly infectious and at-risk for long-term morbidity. In an era in which the number of syphilis cases is increasing sharply both in Western Europe and the United States, all physicians should be aware for the typical and atypical early syphilitic manifestations as they represent opportunities of paramount importance for treatment and epide- mic control.

Introduction: Sexually transmitted infections (STIs) are a significant public health problem worldwide. They are more frequent in young men; however the prevalence in older individuals is increasing. The aim of this study was to access the prevalence of STIs diagnosis in men aged 50 years and older. We also aimed to compare the demographic and behavioral characteristics of those diagnosed with STIs and those with non-STI conditions. Methods: We conducted a retrospective study including all men aged 50 years and older who have attended a Sexual Transmitted Diseases (STD) clinic of a central hospital in Lisbon, Portugal, between July 2015 and December 2017. Results: Between July 2015 and December of 2017, 1722 men attended the STD clinic, of which 323 (18.8%) were aged 50 years and older. Out of these 323 men, 137 (41.4%) were diagnosed with a STI, more often anogenital warts (32.9%), genital herpes simplex virus infection (19.7%) and early syphilis (19.0%). The mean age of the patients with a STI was 59.9 years and almost all (90.5%) reported an inconsistent use of a condom (90.5%). The number of men that have sex with men (MSM) was significantly higher in patients with a STI (p = 0,003) than those with a non-STI diagnosis. Additionally, 40 (29.2%) of these STI patients had been previously infected with the human immunodeficiency virus (HIV) and 33 (24.1%) had a past history for syphilis, which were significantly higher than in patients in patients with a non-STI diagnosis (p = 0.015 and p = 0.001, respectively). Conclusion: Existing data on STI has mainly focused younger population with few studies performed in older individuals. Our study reports a large number of men aged 50 years and older that allows a better understanding of this age group. High levels of unsafe sex and previous diagnosis of HIV and syphilis emphasizes the importance of sexual health promotion in older individuals.

Fungal invasive infections are rare in general population but are an emergent cause of infection in the immunocompromized population, especially in the solid organ transplant recipients. Herein the authors report a clinical case of a liver transplanted patient suffering a cutaneous co-existent infection with A. alternata as well as A. infectoria. To our knowledge this is the first case of cutaneous concomitant infection due to those two species reported not only in Portugal but also worldwide. The patient was treated with surgical excision of the lesions and oral itraconazol without relapse.

Alopecia ,Neurofibroma ,Scalp ,Dermatology ,RL1-803 - Abstract
Although infrequent, alopecia can be caused by benign cutaneous tumours. Neurofibromas are common benign tumors that originate in the peripheral nerve sheath. Diffuse neurofibroma is a rare variant of neurofibroma that is thought to occur mainly in the head and neck of children and young adults. Histology generally shows an infiltrative tumor, composed of spindle cells in the dermis and subcutaneous tissue. Despite being rare, malignant transformation has been reported. The association between diffuse neurofibromas and neurofibromatosis type 1 still remains to be determined since some authors question the low incidence usually described. We report the case of a 42-year-old man who had a diffuse neurofibroma on the scalp presenting as alopecic plaques.

A infecção genital por Chlamydia trachomatis (Ct) é frequentemente assintomática e quando não tratada precocemente constitui um problema major de saúde pública. Os autores realizaram um estudo cujo objectivo foi determinar a prevalência de infecção genital por Ct numa consulta de Infecções Sexualmente Transmissíveis (ISTs) e realizar uma análise de diferentes variáveis. Para tal foi realizado um estudo retrospectivo dos doentes com diagnóstico de infecção por Ct confirmado por técnica de amplificação de ácidos nucleicos, observados na consulta de ISTs do Serviço de Dermatologia e Venereologia do Hospital Curry Cabral entre Janeiro de 2006 e Dezembro de 2009. Encontrou-se uma prevalência de infecção de 10,5% (81 doentes com infecção genital por Ct em 771 indivíduos testados). Na população com infecção por Ct foram encontradas diferenças com significado estatístico entre o sexo masculino e feminino na idade média dos doentes (homens=28,9 vs mulheres=24,3) p= 0,018; no número de companheiros sexuais nos últimos 6 meses (homens=3,32 vs mulheres=1,50) p=0,009; e no tempo em semanas decorrido entre o início dos sintomas e o diagnóstico (homens=2,65 vs mulheres=6,64) p= 0,032. Os doentes com co-infecção pelo Vírus da Imunodeficiência Humana (VIH) tinham um maior número de companheiros sexuais nos últimos 6 meses do que os não VIH p=0,003. Assim, existem diferenças demográficas, comportamentais e clínicas entre o sexo masculino e feminino e entre a população VIH e não VIH. Além disso, a elevada prevalência de infecção por Ct justifica os programas de diagnóstico precoce instituídos.

Introdução: Os homens que têm sexo com homens, particularmente os infectados pelo vírus da imunodeficiência humana (VIH) têm risco aumentado de cancro anal. Ao contrário da maior parte das doenças oportunistas e/ou definidoras de SIDA, os dados são contraditórios no que diz respeito ao efeito da terapêutica antirretrovírica, não sendo claro o impacto da supressão virológica e reconstituição imunitária na evolução da infecção por vírus do papiloma humano (HPV) e prevenção das neoplasias associadas. Actualmente é já recomendada a vacinação de doentes com infecção por VIH contra o HPV; os programas de rastreio do cancro anal, recomendados por algumas organizações, carecem ainda de validação definitiva da sua eficácia. Material e Métodos: Os autores fizeram um estudo retrospectivo dos casos de cancro anal diagnosticados entre 2000-2015 em doentes com infecção por VIH em seguimento no serviço de Infecciologia do Hospital de Curry Cabral, em Lisboa. São avaliadas as características clínicas e epidemiológicas dos doentes com cancro do canal anal ao longo de um período de quinze anos. Resultados: O cancro anal foi diagnosticado em dez doentes, maioritariamente homens HSH, com infecção por VIH com uma duração média de 15,1 anos, com contagem média de linfócitos TCD4+ de 441 células/uL. O diagnóstico foi mais frequentemente realizado no estádio III e o tratamento mais frequente foi cirúrgico, ocasionalmente conjugado com radioterapia. Faleceram 4 doentes. Conclusões: São necessários programas de rastreio consensuais do cancro anal, a par da necessidade de reforço da vacinação contra o HPV nos homens, nomeadamente nos homens que têm sexo com homens, com ou sem infecção por VIH.

A sarcoidose consiste numa doença inflamatória multissistémica, de etiologia desconhecida, que se caracteriza pela formação de granulomas não-caseosos nos órgãos envolvidos, predominantemente pulmões e gânglios intratorácicos. O envolvimento cutâneo ocorre em cerca de 25-35% dos casos, é habitualmente um achado precoce e constitui um local acessível e seguro para estudo histológico. As lesões cutâneas podem ter várias apresentações, incluindo pápulas, nódulos, placas e cicatrizes infiltradas. O diagnóstico baseia-se no reconhecimento das características clínicas, imagiológicas e histológicas e exclusão de outras doenças granulomatosas. O diagnóstico precoce e tratamento sistémico (quando necessário) poderão prevenir complicações futuras.

Introdução: Assistiu-se nas últimas décadas a um aumento do número de casos de gonorreia notificados na Europa. Material e métodos: Foram revistos de forma retrospectiva os processos clínicos dos doentes observados na Consulta de IST do Hospital de Curry Cabral durante o período compreendido entre Janeiro de 2006 e Dezembro de 2013 (8 anos). O rastreio para a infecção por Neisseria gonorrhoeae é realizado em todos os doentes de forma sistemática através de técnica de diagnóstico molecular (BD Probetec-SDA system). Os autores procederam à caracterização epidemiológica e sociodemográfica bem como determinação da frequência da infecção por N. gonorrhoeae e respectivas localizações. Resultados: Durante o período em análise, num universo de 1735 doentes, foi diagnosticada gonorreia em 114 casos (6,6%), 104 em homens e 10 em mulheres, com uma mediana de idades de 29 anos. O diagnóstico de gonorreia verificou-se em 63 homens que têm sexo com homens (HSH) e 41 homens que têm sexo com mulheres. Dos doentes com diagnóstico de gonorreia, 26 eram seropositivos para o VIH (23%). A localização uro-genital foi a mais frequente, com 103 casos, seguindo-se a infecção do recto em 12 doentes e infecção da orofaringe em 9 doentes. De todos estes diagnósticos, 17% ocorreram em localizações nas quais os doentes não referiram sintomas (13 homens e 5 mulheres). Conclusões: Os resultados deste trabalho foram semelhantes aos dados publicados recentemente na literatura. Salienta-se o elevado número de casos em HSH. Neste contexto epidemiológico, a identificação deste agente em localizações sem queixas não é negligenciável, realçando a importância do rastreio extragenital em doentes assintomáticos nessas localizações.

Apresenta-se o caso de um doente de 46 anos, com coinfecção VIH-1/VHC e cirrose hepática, internado por febre, prostração e astenia. Ao exame objetivo, observavam-se escassas pústulas necróticas em base eritematosa acantonadas aos dedos das mãos e pés com edema, dor e limitação funcional dos mesmos e da articulação tíbio-társica esquerda. Analiticamente, apenas elevação ligeira da enzimologia hepática e da PCR. Admitiram-se as hipóteses diagnósticas de endocardite, meningococcémia ou gonococcémia. Após isolamento de Neisseria gonorrhoeae em hemocultura, iniciou-se ceftriaxone 1g/dia EV com melhoria clínica. A positividade da PCR para N. gonorrhoeae no exsudado orofaríngeo confirmou o diagnóstico de gonococcémia disseminada de ponto de partida orofaríngeo. A gonorreia é uma infeção sexualmente transmitida causada pelo diplococo Gram negativo Neisseria gonorrhoeae. A gonococcémia disseminada na forma da síndrome clássica “dermatite-artrite” acompanha apenas 1-2% das infeções mucosas. A gonorreia orofaríngea é geralmente assintomática em homens e mulheres, constituindo provavelmente um reservatório importante do agente. O aumento da incidência de gonorreia torna este caso pertinente na prática clínica actual do dermatologista.

A dermatoscopia constitui uma técnica de diagnóstico não-invasiva, in vivo, que permite complementar a observação clínica de lesões cutâneas não-pigmentadas de etiologia diversa. Nos tumores cutâneos não-pigmentados, a dermatoscopia facilita a observação de estruturas vasculares, aumentando a acuidade no seu diagnóstico, distinguindo tumores melanocíticos e não-melanocíticos, benignos e malignos. Na parte II descreve-se a variabilidade da aplicação clínica da dermatoscopia em lesões cutâneas não-pigmentadas tumorais.

A presença simultânea na mesma lesão de neoplasias cutâneas distintas designa-se por tumor composto ou de colisão, sendo considerada pouco frequente. Os autores descrevem o caso de um homem de 66 anos, observado por placa acastanhada de superfície verrucosa. Observou-se na região malar esquerda uma placa com 8 mm de maior eixo, limites mal definidos, coloração acastanhada e de superfície verrucosa, com bordo parcialmente eritematoso, com presença de múltiplas telangiectasias. A observação dermatoscópica evidenciou uma lesão não-melanocítica, distinguindo-se a combinação de múltiplos pseudo-quistos de milia (mais evidentes com luz não-polarizada), eritema e vasos arboriformes, com ramificações de menor calibre, na periferia (mais evidentes com luz polarizada). A primeira estrutura é característica de queratose seborreica, enquanto que as estruturas vasculares apresentam elevado valor preditivo positivo para o diagnóstico de carcinoma basocelular. A avaliação histopatológica confirmou os diagnósticos dermatoscópicos, com achados comuns às referidas neoplasias. A raridade deste tumor combinado contrasta com a prevalência das queratoses seborreicas. A dermatoscopia poderá constituir um complemento fundamental na sua abordagem, porque permite a observação de padrões de diagnóstico nem sempre evidentes do ponto de vista clínico, constituindo uma informação adicional à avaliação histopatológica.

O eritema exsudativo multiforme representa uma síndroma mucocutânea, imuno-mediada, resultante de mecanismos de hipersensibilidade associados a causas infecciosas ou farmacológicas. Nas primeiras verifica-se um predomínio da infecção pelo vírus herpes simples. A associação com a infecção por Mycobaterium tuberculosis é menos frequente. Os autores descrevem o caso de um doente de 35 anos, internado por eritema exsudativo multiforme possivelmente associado a infecção pulmonar por Mycobacterium tuberculosis, com favorável evolução clínica após o início de terapêutica com isoniazida, rifampicina, pirazinamida e etambutol.

As Estatinas são um grupo farmacológico muito utilizado atualmente. São habitualmente bem toleradas, no entanto, podem estar implicadas na génese/agravamento de doenças auto-imunes como Lupus Eritematoso Cutâneo. Descreve-se o caso de uma doente caucasóide, de 74 anos que, 18 meses após início de terapêutica com sinvastatina, desenvolveu uma dermatose localizada à raiz dos membros superiores e dorso, constituída por pápulas e placas eritematosas, anulares e com superfície descamativa. Analiticamente era de salientar presença de ANA e anticorpos anti-SSA. O exame histopatológico foi consistente com a hipótese clínica de Lupus Eritematoso Cutâneo Subagudo. Após a suspensão da Sinvastatina assistiu-se à resolução completa do quadro clínico e laboratorial. O Lupus Eritematoso Cutâneo induzido por fármacos é uma entidade muitas vezes indistinguível das formas idiopáticas. Apesar de frequentemente ter uma evolução e prognóstico favoráveis, salienta-se a sua importância pelo possível envolvimento sistémico associado e pelas sequelas cutâneas, por vezes desfigurantes.

Cerca de 30% dos adultos com morfeia apresentam simultaneamente outras doenças auto-imunes, o que suporta a presença de mecanismos de auto-imunidade na patogénese desta doença fibrosante da pele e tecidos subjacentes. Os autores descrevem o caso de um doente do sexo masculino, 27 anos, que notou o aparecimento na região abdominal, cerca de 1 ano antes da observação, de placa eritematosa, ovalada, endurada, assintomática, com crescimento progressivo. Referiu vitiligo acro-facial desde os 12 anos de idade e antecedentes maternos de vitiligo e tiroidite de Hashimoto. A avaliação histopatológica evidenciou escasso infiltrado inflamatório perivascular e espessamento das fibras de colagénio, suportando o diagnóstico clínico de morfeia. Na avaliação laboratorial destacou-se a marcada elevação no título do auto-anticorpo anti-descarboxilase do ácido glutâmico, permitindo o diagnóstico de diabetes auto-imune latente do adulto (LADA), uma forma de diabetes tipo 1 de início tardio. A morfeia e o vitiligo são dermatoses raramente descritas em simultâneo, apesar da sua provável etiologia auto-imune. Neste doente, a investigação de outras doenças auto-imunes permitiu o diagnóstico de LADA. Esta associação, raramente descrita, favorece a hipótese auto-imune.

Dermatology ,RL1-803 ,Infectious and parasitic diseases ,RC109-216 - Abstract
Introdução: A resistência aos antibióticos em Neisseria gonorrhoeae tem-se revelado um importante problema de saúde pública mundial, estando a levantar grandes dificuldades em termos de opções terapêuticas em alguns países. Objectivo: Rever o panorama (nacional e internacional) da resistência aos antibióticos em Neisseria gonorrhoeae. Material e Métodos: Pesquisa de artigos em revistas nacionais e internacionais (estas últimas com in- dexação na Pubmed/Medline e redigidas em inglês). Utilizaram-se como palavras-chave: “Neisseria gonorrhoeae antibiotic resistance”. Resultados: As cefalosporinas de terceira geração (ceftriaxone e cefixima), associadas ou não à azitromicina, substituíram as fluoroquinolonas como fármacos de primeira linha no tratamento da gonorreia. Os rela- tos de resistência às cefalosporinas são ainda relativamente escassos; contudo, o aumento da concentração inibitória mínima (CIM), traduzido pela diminuição da sensibilidade a esta classe de antibióticos, tem vindo a ser regularmente descrita. Por outro lado, a resistência à azitromicina foi relatada em vários países. Em Portugal, já foram reportados casos de Neisseria gonorrhoeae resistentes à azitromicina mas não às cefalosporinas. Porém, estirpes com diminuição da sensibilidade às cefalosporinas foram já detetadas. Conclusão: Novas alternativas terapêuticas são indispensáveis para o tratamento das infeções por Neisseria gonorrhoeae, bem como condutas adequadas por parte dos médicos e dos doentes e seus contactantes. PALAVRAS-CHAVE – Antibióticos; Resistência antibiótica; Neisseria gonorrhoeae; Guideline.

Previously, we identified a Chlamydia trachomatis Lymphogranuloma venereum (LGV) recombinant strain possessing a unique non-LGV ompA genotype. Here, culture-independent genome sequencing confirms its circulation in Europe, Middle East and North America, and unveils genetic evidence of emergence of antibiotic resistance. Multi-country and systematic molecular surveillance is needed.

Publisher Copyright: © 2022 European Centre for Disease Prevention and Control (ECDC). All rights reserved. Up to 27 May 2022, Portugal has detected 96 confirmed cases of monkeypox. We describe 27 confirmed cases (median age: 33 years (range: 22–51); all males), with an earliest symptom onset date of 29 April. Almost all cases (n = 25) live in the Lisbon and Tagus Valley health region. Most cases were neither part of identified transmission chains, nor linked to travel or had contact with symptomatic persons or with animals, suggesting the possible previously undetected spread of monkeypox. publishersversion published

The quadrivalent human papillomavirus (HPV) vaccine was introduced in the Portuguese National Immunization Program in October 2008, targeting 13-year-old girls. This study aimed at evaluating the impact of HPV vaccination on the epidemiology of genital warts (GWs) in Portugal.Observational, retrospective chart review study conducted at two free-of-charge walk-in sexually transmitted diseases (STD) clinics in Lisbon region. The medical records of all patients attending a first STD consultation at the study centers between May 2006 and December 2017 (observation period) were reviewed. The number of patients diagnosed with GWs and/or chlamydial infection at each year was documented and used to determine yearly prevalence of both conditions throughout the observation period. We broke down the observation period into pre-vaccination (May 2006 to December 2008) and vaccination (January 2009 to December 2017) periods.Most patients were male (69.5%) and aged ≥ 25 years (78.1%). The majority of male patients were men who have sex with women (62.0%). Marked decreases in the prevalence of GWs between the last year of the pre-vaccination period (2008) and the last year of the observation period (2017) were found for female patients aged ≤ 19 and 20-24 years (86.8% and 77.4%, respectively). Lower decreases were observed for male patients of the same age groups (38.5% and 19.3%, respectively). GWs prevalence increased among patients ≥ 25 years (9.7% and 14.7% among female and male patients, respectively). Overall prevalence of chlamydial infection increased by 75.9% between 2008 and 2017.This study contributes to the body of evidence showing that public HPV vaccination programs are effective in reducing the prevalence of GWs among vaccine-eligible patients. HPV vaccination program may significantly reduce the burden associated with GWs in Portugal.

Commentary: G. Ciccarese et al. J Eur Acad Dermatol Venereol 2021; 35:1606-1607. https://doi.org/10.1111/jdv.17468. Background: Lymphogranuloma venereum (LGV) is a sexual transmitted infection (STI), currently endemic within the population of men who have sex with men (MSM) of Western Countries. L2B variant has been reported as the predominant strain in the current LGV epidemics, although a shift towards L2-434 has been observed in some European countries. Objectives: To evaluate and characterize the population with LGV infection diagnosed in Centro Hospitalar Universitário de Lisboa Central, Lisbon, Portugal. Methods: A retrospective analysis of all LGV diagnoses between 2016 and 2019 was performed. The diagnosis was established through ompA-genotyping of samples yielding a positive result to Chlamydia trachomatis (CT). All considered samples were retrieved from the clinician activity, through swabbing and urine analysis and CT infection diagnosis was obtained using real-time PCR. Results: During the period studied 16 279 CT diagnostics tests were employed, with a striking increase from 2016 (n = 467) to 2019 (n = 9362). A total of 1602 diagnoses of CT were established, from which 168 (10.5%) corresponded to LGV, with both infections showing a rising evolution, between 2016 and 2019, of 2.9 and 2.7 times, respectively. The majority of the LGV strains were genotyped as L2/434 (67.3%; n = 113). LGV predominantly affected MSM and men who have sex with men and women (97.0%; n = 163). Anorectal infection was the most prevalent one (90.5%; n = 152), being proctitis the main clinical presentation (76.2%; n = 128). Absence of symptoms was reported in almost 15% of the cases (n = 24). The presence of concomitant infection with human immunodeficiency virus was dominant (73.2%; n = 123) and the prevalence of one or more STI co-infections was about 60.1% (n = 99). Conclusions: An increasing evolution of CT and LGV testing and diagnosing was observable throughout the studied period. Characteristics of the population are similar with those described within LGV epidemics. In accordance with recent European studies, predominance towards L2 genotype was identified. info:eu-repo/semantics/publishedVersion

Bullous pemphigoid is an autoimmune bullous cutaneous disease. We report the case of a 60 year-old male patient whose kidney allograft failed and was on hemodialysis for the previous 16 months. After tapering immunosuppressive medication, he presented simultaneous bullous eruption and kidney allograft intolerance syndrome. Investigation showed a positive BP180 anti-basement membrane zone antibody and skin biopsy was consistent with bullous pemphigoid. The patient was treated with corticotherapy and bullous pemphigoid resolved. The development of new onset diabetes and concerns over long term immunosuppression, halted the decision to continue corticotherapy and the patient underwent graft nephrectomy, with resolution of the kidney allograft intolerance syndrome without recurrence of the bullous disease. The occurrence of bullous pemphigoid in patients with failed renal allograft is rare, with only eleven cases reported in literature. This case illustrates how graft nephrectomy can provide a definitive cure to bullous pemphigoid in this setting.

Chlamydia trachomatis is the most prevalent sexually transmitted bacterium worldwide and the causative agent of trachoma. Its strains are classified according to their ompA genotypes, which are strongly linked to differential tissue tropism and disease outcomes [ocular disease, urogenital disease and lymphogranuloma venereum (LGV)]. While the genome-based species phylogenetic tree presents four main clades correlating with tropism/prevalence, namely ocular, LGV, urogenital T1 (more prevalent genotypes) and urogenital T2 (less prevalent genotypes), inter-clade exchange of ompA is considered a rare phenomenon probably mediating marked tropism alterations. An LGV epidemic, associated with the clonal expansion of the L2b genotype, has emerged in the last few decades, raising concerns particularly due to its atypical clinical presentation (ulcerative proctitis) and circulation among men who have sex with men (MSM). Here, we report an LGV outbreak, mostly affecting human immunodeficiency virus-positive MSM engaging in high-risk sexual practices, caused by an L2b strain with a rather unique non-LGV ompA signature that precluded the laboratory notification of this outbreak as LGV. C. trachomatis whole-genome capture and sequencing directly from clinical samples was applied to deeply characterize the genomic backbone of this novel LGV outbreak-causing clone. It revealed a chimeric genome structure due to the genetic transfer of ompA and four neighbouring genes from a serovar D/Da strain, likely possessing the genomic backbone associated with the more prevalent urogenital genotypes (T1 clade), to an LGV (L2b) strain. The hybrid L2b/D-Da strain presents the adhesin and immunodominant antigen MOMP (major outer membrane protein) (encoded by ompA) with an epitope repertoire typical of non-invasive genital strains, while keeping the genome-dispersed virulence fingerprint of a classical LGV strain. As previously reported for inter-clade ompA exchange among non-LGV clades, this novel C. trachomatis genomic mosaic involving a contemporary epidemiologically and clinically relevant LGV strain may have implications on its transmission, tissue tropism and pathogenic capabilities. The emergence of variants with epidemic and pathogenic potential highlights the need for more focused surveillance strategies to capture C. trachomatis evolution in action. info:eu-repo/semantics/publishedVersion

Chlamydia trachomatisis the most prevalent sexually transmitted bacteria worldwide and the causative agent of blinding trachoma. Strains are classified based onompAgenotypes, which are strongly linked with differential tissue tropism and disease outcomes. A lymphogranuloma venereum (LGV) epidemics, characterized by ulcerative proctitis, has emerged in the last two decades (mainly L2b genotype), raising high concern especially due to its circulation among men who have sex with men (MSM). Here, we report an ongoing outbreak (mostly affecting HIV-positive MSM engaging in high-risk practices) caused by an L2b strain with a rather unique genome makeup that precluded the laboratory notification of this outbreak as LGV due to its non-LGVompAsignature. Homologous recombination mediated the transfer of a ~4.5Kbp fragment enrollingCT681/ompAand neighboring genes (CT677/rrf, CT678/pyrH, CT679/tsf, CT680/rpsB) from a serovar D/Da strain likely possessing the typical T1 clade genome backbone associated with most prevalent genotypes (E and F). The hybrid L2b/D-Da strain presents the adhesin and immunodominant antigen MOMP (coded byompA) with an epitope repertoire typical of non-invasive genital strains, while keeping the genome-dispersed virulence fingerprint of a classical LGV (L2b) strain. As previously reported for inter-cladeompAexchange among non-LGV clades, this unprecedentedC. trachomatisgenomic mosaic involving a contemporary epidemiologically and clinically relevant LGV strain may have implications on its transmission, tissue tropism and pathogenic capabilities. The emergence of such variants with epidemic and pathogenic potential highlights the need of more oriented surveillance strategies focused on capturing the C.trachomatisevolution in action.

Background Portugal has the highest prevalence rate of HIV infection in Western Europe. The proportion of patients with a late diagnosis, carried out in full-blown AIDS stage, remains high. Skin and mucous membrane manifestations are not rare in these patients. Objective A demographic, clinical, and laboratorial characterization of patients with de novo HIV infection diagnosis made in the Department of Dermatology and Venereology of a central hospital in Lisbon, Portugal. Methods Retrospective review of medical records of adult patients newly diagnosed with HIV infection (reactive immunoassay for antibodies to HIV-1/HIV-2 or HIV p24 antigen) in the Dermatology and Venereology Department of a Portuguese central hospital in the period between January 2005 and December 2013. Results During the study period, 97 new cases were diagnosed, 70 men and 27 women. The median age at diagnosis was 36 years. Of the total, 50 cases were diagnosed with a concomitant sexually transmitted infection (STI), more frequently syphilis and ano-genital HPV infection. The remaining 47 patients were diagnosed with other dermatological conditions such as prurigo nodularis, psoriasis, and Kaposi’s sarcoma. The duration of complaints that lead to medical attention ranged from Conclusion This study grants a descriptive overview of de novo HIV infection diagnoses performed by dermatovenereologists in a central hospital in Lisbon, Portugal. As in the past, the importance of Dermato–Venereology for HIV infection diagnosis remains present in daily clinical practice.
