Pingarilho, M; Pimentel, V; Miranda, M; Silva, AR; Diniz, A; Ascenção, B; Piñeiro, C; Koch, C; Rodrigues, C; Caldas, C; Morais, C; Faria, D; Gomes da Silva, E; Teófilo, E; Monteiro, F; Roxo, F; Maltez, F; Rodrigues, F; Gaião, G; Ramos, H; Costa, I; Germano, I; Simões, J; Oliveira, J; Ferreira, J; Poças, J; Saraiva da Cunha, J; Soares, J; Henriques, J; Mansinho, K; Pedro, L; Aleixo, MJ; Gonçalves, MaJ; Manata, MJ; Mouro, M; Serrado, M; Caixeiro, M; Marques, N; Costa, O; Pacheco, P; Proença, P; Rodrigues, P; Pinho, R; Tavares, R; Correia de Abreu, R; Côrte-Real, R; Serrão, R; Sarmento e Castro, R; Nunes, S; Faria, T; Baptista, T; Martins, MR; Gomes, P; Mendão, L; Simões, D; Abecasis, AObjective: 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 used for subtyping, TDR determination, and transmission cluster (TC) analyses. Results: In Portugal, the overall prevalence of TDR between 2014 and 2019 was 11.0%. TDR presented a decreasing trend from 16.7% in 2014 to 9.2% in 2016 (p for-trend = 0.114). Multivariate analysis indicated that TDR was significantly associated with transmission route (MSM presented a lower probability of presenting TDR when compared to heterosexual contact) and with subtype (subtype C presented significantly more TDR when compared to subtype B). TC analysis corroborated that the heterosexual risk group presented a higher proportion of TDR in TCs when compared to MSMs. Among subtype A1, TDR reached 16.6% in heterosexuals, followed by 14.2% in patients infected with subtype B and 9.4% in patients infected with subtype G. Conclusion: Our molecular epidemiology approach indicates that the HIV-1 epidemic in Portugal is changing among risk group populations, with heterosexuals showing increasing levels of HIV-1 transmission and TDR. Prevention measures for this subpopulation should be reinforced.
- HIV-Associated Facial Lipodystrophy: Experience of a Tertiary Referral Center With Fat and Dermis-Fat Compound Graft TransferPublication . Martins de Carvalho, F; Casal, D; Bexiga, J; Sousa, J; Martins, J; Teófilo, E; Maltez, F; Germano, I; Videira e Castro, JObjectives: HIV-associated lipodystrophy is a common comorbidity in HIV-infected patients, having a profound impact on every aspect of patients' lives, particularly when involving the face. Hence, it is of the utmost importance to evaluate the result of any potential therapies that may help solve HIV-associated facial lipodystrophy. The aim of this article was to evaluate the outcome of patients undergoing facial lipodystrophy correction surgery within our institution. Methods: A retrospective analysis of the clinical charts and iconographic information of patients regarding demographics, morphologic changes, surgical option, postoperative complications, results, and patient satisfaction assessed by a 1- to 10-point scale and by the Assessment of Body Change and Distress questionnaire. Results: Twenty-three patients were operated on from March 2011 to April 2015. Seventy-five percent of cases were treated with fat graft injection, whereas dermis-fat grafts were applied in 25% of patients. The former had their fat harvested more commonly from the abdomen, whereas in the latter case, the graft was harvested mostly from the inner aspect of arms. The mean volume of fat injected on each side of the face was 28.5 ± 22.7 mL. On a scale from 1 to 10, mean patient satisfaction was 7.7 ± 2.8. The Assessment of Body Change and Distress questionnaire revealed statistically significant improvements. Complications occurred in 25% of cases, the most frequent being significant reabsorption. No major complications occurred. Conclusions: Treatment of HIV-associated facial lipodystrophy with autologous fat or dermis-fat compound graft is a safe procedure with long-lasting results and unquestionable aesthetic and social benefits.

- Sarcoma de Kaposi Pulmonar na Infecção por VIHPublication . Teófilo, E; Figueiredo, PO aparecimento recente do sarcoma de Kaposi (SK)epidémico na prática clínica corrente da Medicina Interna veio permitir encontrar expressões clínicas raras, como a pulmonar (SKP). A radiologia tem um papel preponderante na avaliação da extensão do SKP. A grande agressividade que por vezes apresenta conduziu à investigação de novas terapêuticas em diferentes áreas (imunomodulação, hormonal e citostática). Os novos conceitos quanto à sua provável origem talvez permitam que, a curto prazo, seja mais uma profilaxia nos imunodeprimidos pelo VIH.
- Sociodemographic, Clinical, and Behavioral Factors Associated With Sexual Transmitted Infection Among HIV-1 Positive Migrants in Portugal: Are There Differences Between Sexes?Publication . Miranda, M; Pimentel, V; Graça, J; Seabra, S; Sebastião, C; Diniz, A; Faria, D; Teófilo, E; Roxo, F; Maltez, F; Germano, I; Oliveira, J; Ferreira, J; Poças, J; Mansinho, K; Mendão, L; Gonçalves, MJ; Mouro, M; Marques, N; Pacheco, P; Proença, P; Tavares, R; Correia de Abreu, R; Serrão, R; Faria, T; O. Martins, MR; Gomes, P; Abecasis, A; Pingarilho, MIntroduction: 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 STIs in a population of HIV-positive migrants living in Portugal. Methodology: This is a cross-sectional observational study of 265 newly diagnosed HIV-1 positive migrants, who were defined as individuals born outside Portugal. This group of people were part of the BESTHOPE study that was developed in 17 Portuguese hospitals between September 2014 and December 2019, and included information collected through sociodemographic and behavioral questionnaires filled in by the migrant patients, clinical questionnaires filled in by the clinicians and HIV-1 genomic sequences generated through resistance testing (Sanger sequencing). A multivariable statistical analysis was used to analyze the association between sociodemographic characteristics, sexual behaviors, HIV testing and sexual infections. Results: Most HIV-1 positive individuals included in the study were men (66.8%) and aged between 25 and 44 years old (59.9%). Men had a higher proportion of STIs when compared to women (40.4% vs. 14.0%) and the majority of men reported homosexual contacts (52.0%). Most men reported having had two or more occasional sexual partners in the previous year (88.8%) and 50.9% reported always using condoms with occasional partners, while 13.2% never used it. For regular partners, only 29.5% of the women reported using condoms, compared to 47.3% of men. Other risk behaviors for acquiring HIV, such as tattooing and performing invasive medical procedures, were more prevalent in men (38.0% and 46.2%, respectively), when compared to women (30.4% and 45.1% respectively) and 4.7% of men reported having already shared injectable materials, with no data for comparison in the case for women. Additionally, 23.9% of women reported having had a blood transfusion while only 10.3% of men reported having had this medical procedure. Meanwhile, 30.9% of the individuals reported having been diagnosed with some type of STI in the last 12 months. In addition, 43.3% of individuals that answered a question about hepatitis reported to be infected with hepatitis B, while 13.0% reported having hepatitis C infection. According to the multivariable analysis, the only transmission route was significantly associated with reports of previous STI infection: men who have sex with men (MSM) were 70% more likely to have been diagnosed with an STI in the past 12 months compared to the heterosexual route. Conclusion: HIV-1 infected men were more likely to report previous STIs than women. On the other hand, most migrant women had a regular sexual partner and never or only sometimes used condoms. This somewhat discrepant findings suggest that gender inequalities may make women unable to negotiate safe sexual practices, resulting in increased susceptibility to infection. However, since migrant women report less STIs, we cannot exclude that these STIs may remain undiagnosed. The implementation of safer sex awareness campaigns for condom use and screening for STIs in women is crucial. On the other hand, health education campaigns for STI knowledge need to be implemented for both MSM and women and their partners.

- The Demise of Multidrug-Resistant HIV-1: the National Time Trend in PortugalPublication . Vercauteren, J; Theys, K; Carvalho, AP; Valadas, E; Duque, LM; Teófilo, E; Faria, T; Faria, D; Vera, J; Aguas, MJ; Peres, S; Mansinho, K; Vandamme, AM; Camacho, ROBJECTIVES: Despite a decreasing mortality and morbidity in treated HIV-1 patients, highly active antiretroviral treatment (HAART) can still fail due to the development of drug resistance. Especially, multidrug-resistant viruses pose a threat to efficient therapy. We studied the changing prevalence of multidrug resistance (MDR) over time in a cohort of HIV-1-infected patients in Portugal. PATIENTS AND METHODS: We used data of 8065 HIV-1-infected patients followed from July 2001 up to April 2012 in 22 hospitals located in Portugal. MDR at a specific date of sampling was defined as no more than one fully active drug (excluding integrase and entry inhibitors) at that time authorized by the Portuguese National Authority of Medicines and Health Products (INFARMED), as interpreted with the Rega algorithm version 8.0.2. A generalized linear mixed model was used to study the time trend of the prevalence of MDR. RESULTS: We observed a statistically significant decrease in the prevalence of MDR over the last decade, from 6.9% (95% CI: 5.7-8.4) in 2001-03, 6.0% (95% CI: 4.9-7.2) in 2003-05, 3.7% (95% CI: 2.8-4.8) in 2005-07 and 1.6% (95% CI: 1.1-2.2) in 2007-09 down to 0.6% (95% CI: 0.3-0.9) in 2009-12 [OR=0.80 (95% CI: 0.75-0.86); P<0.001]. In July 2011 the last new case of MDR was seen. CONCLUSIONS: The prevalence of multidrug-resistant HIV-1 is decreasing over time in Portugal, reflecting the increasing efficiency of HAART and the availability of new drugs. Therefore, in designing a new drug, safety and practical aspects, e.g. less toxicity and ease of use, may need more attention than focusing mainly on efficacy against resistant strains.
