Determinants of HIV-1 Transmission Clusters and Transmitted Drug Resistance in ...
Abrantes, Ricardo; Pimentel, Victor; Sebastião, Cruz; Miranda, Mafalda N S; Seabra, Sofia; Silva, Ana Rita; Diniz, António; Ascenção, BiancaIntroduction: In the EU/EEA, men who have sex with men (MSM) is a priority group for the prevention and control of HIV-1 infection. In Portugal, the 2023 HIV incidence rate was 8.2 per 100,000 inhabitants, with 876 new infections, 41.7% in MSM. We aim to characterize HIV-1 transmission clusters (TC) and transmitted drug resistance (TDR) and its sociodemographic, behavioral, clinical, and viral genomic determina...

Miranda, Mafalda N. S.; Pimentel, Victor; Graça, Jacqueline; Seabra, Sofia G.; Sebastião, Cruz S.; Diniz, António; Faria, Domitília; Teófilo, EugénioIntroduction: Sexually transmitted infections (STIs) continue to occur at high levels. According to the WHO, each year there are an estimated 374 million new infections with syphilis, gonorrhea, chlamydia, and trichomoniasis. STIs are associated with an increased risk of acquiring HIV infection. Migrants are reportedly highly affected by STIs. Objectives: This study aims to characterize factors associated with ...
Determinants of HIV late presentation among men who have sex with men in Portug...
Abrantes, Ricardo; Pimentel, Victor; Miranda, Mafalda N. S.; Silva, Ana Rita; Diniz, António; Ascenção, Bianca; Piñeiro, Carmela; Koch, CarmoIntroduction: HIV late presentation (LP) remains excessive in Europe. We aimed to analyze the factors associated with late presentation in the MSM population newly diagnosed with HIV in Portugal between 2014 and 2019. Methods: We included 391 newly HIV-1 diagnosed Men who have Sex with Men (MSM), from the BESTHOPE project, in 17 countrywide Portuguese hospitals. The data included clinical and socio-behavioral q...
HIV-1 diversity and pre-treatment drug resistance in the era of integrase inhib...
Sebastião, Cruz S.; Abecasis, Ana B.; Jandondo, Domingos; Sebastião, Joana M.; Vigário, João; Comandante, Felícia; Pingarilho, Marta; Pocongo, BárbaraThe surveillance of drug resistance in the HIV-1 naïve population remains critical to optimizing the effectiveness of antiretroviral therapy (ART), mainly in the era of integrase strand transfer inhibitor (INSTI) regimens. Currently, there is no data regarding resistance to INSTI in Angola since Dolutegravir-DTG was included in the first-line ART regimen. Herein, we investigated the HIV-1 genetic diversity and ...

Detection of JCV or BKV viruria and viremia after kidney transplantation is not...
Querido, Sara; Weigert, Andre; Pinto, Iola; Papoila, Ana Luísa; Pessanha, Maria Ana; Gomes, Perpétua; Adragão, Teresa; Paixão, PauloStudies analyzing the relationship between BK polyomavirus (BKV) or JC polyomavirus (JCV) infection and kidney transplant (KT) long term clinical outcomes are scarce. Therefore, we evaluated this relationship in a single-center retrospective cohort of 288 KT patients followed for 45.4(27.5; 62.5) months. Detection of BKV viremia in two consecutive analyses led to discontinuation of antimetabolite and initiation...
HIV-1-Transmitted Drug Resistance and Transmission Clusters in Newly Diagnosed ...
Pingarilho, Marta; Pimentel, Victor; Miranda, Mafalda N. S.; Silva, Ana Rita; Diniz, António; Ascenção, Bianca Branco; Piñeiro, Carmela; Koch, CarmoObjective: To describe and analyze transmitted drug resistance (TDR) between 2014 and 2019 in newly infected patients with HIV-1 in Portugal and to characterize its transmission networks. Methods: Clinical, socioepidemiological, and risk behavior data were collected from 820 newly diagnosed patients in Portugal between September 2014 and December 2019. The sequences obtained from drug resistance testing were us...
