RESUMO
INTRODUCTION: 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.
RESUMO
Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by an invasive form of Chlamydia trachomatis, typically affecting the anogenital area with regional lymphatic involvement. Extragenital manifestations are rare but can occur, particularly if the bacterium is inoculated out of the genital tract. To our knowledge, only 13 cases of symptomatic neck LGV have been published so far in the medical literature. We describe a case of a young man living with HIV with bilateral, rapid-growing and painful neck swelling, whose definite diagnosis was challenging. The patient underwent extensive investigation, including repeated ultrasound-guided fine-needle aspirations, microbiological exams and histological characterisation. Genotyping revealed C. trachomatis L2 serovar, confirming LGV as a final diagnosis, affecting neck lymph nodes. Treatment with doxycycline combined with surgical drainage led to clinical resolution. This case emphasises the importance of a comprehensive testing strategy to identify LGV, especially in individuals reporting unprotected oral sex, with unexplained neck lymphadenitis.

BACKGROUND: Seroepidemiological studies provide estimates of population-level immunity, prevalence/incidence of infections, and evaluation of vaccination programs. We assessed the seroprevalence of protective antibodies against influenza and evaluated the correlation of seroprevalence with the cumulative annual influenza incidence rate. METHODS: We conducted an annual repeated cross-sectional seroepidemiological survey, during June-August, from 2014 to 2019, in Portugal. A total of 4326 sera from all age groups, sex, and regions was tested by hemagglutination inhibition assay. Seroprevalence and geometric mean titers (GMT) of protective antibodies against influenza were assessed by age group, sex, and vaccine status (65+ years old). The association between summer annual seroprevalence and the difference of influenza incidence rates between one season and the previous one was measured by Pearson correlation coefficient (r). RESULTS: Significant differences in seroprevalence of protective antibodies against influenza were observed in the population. Higher seroprevalence and GMT for A(H1N1)pdm09 and A(H3N2) were observed in children (5-14); influenza B seroprevalence in adults 65+ was 1.6-4.4 times than in children (0-4). Vaccinated participants (65+) showed significant higher seroprevalence/GMT for influenza. A strong negative and significant correlation was found between seroprevalence and ILI incidence rate for A(H1N1)pdm09 in children between 5 and 14 (r = -0.84; 95% CI, -0.98 to -0.07); a weak negative correlation was observed for A(H3N2) and B/Yamagata (r ≤ -0.1). CONCLUSIONS: The study provides new insight into the anti-influenza antibodies seroprevalence measured in summer on the ILI incidence rate in the next season and the need for adjusted preventive health care measures to prevent influenza infection and transmission.

Introduction: 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 questionnaires and the viral genomic sequence obtained in the drug resistance test before starting antiretrovirals (ARVs). HIV-1 subtypes and epidemiological surveillance mutations were determined using different bioinformatics tools. Logistic regression was used to estimate the association between predictor variables and late presentation (LP). Results: The median age was 31 years, 51% had a current income between 501-1,000 euros, 28% were migrants. 21% had never been tested for HIV before diagnosis, with 42.3% of MSM presenting LP. 60% were infected with subtype B strains. In the multivariate regression, increased age at diagnosis, higher income, lower frequency of screening, STI ever diagnosed and higher viral load were associated with LP. Conclusion: Our study suggests that specific subgroups of the MSM population, such older MSM, with higher income and lower HIV testing frequency, are not being targeted by community and clinical screening services. Overall, targeted public health measures should be strengthened toward these subgroups, through strengthened primary care testing, expanded access to PrEP, information and promotion of HIV self-testing and more inclusive and accessible health services.

Cytomegalovirus (CMV) infection is a common and typically benign disease in immunocompetent individuals. However, immunocompromised patients are at a greater risk of reactivation, leading to more severe outcomes. Patients with rheumatic diseases have a particularly high risk of opportunistic infections due to both the inherent immunosuppressive state conveyed by the disease itself and the use of potent immunosuppressant drugs, such as glucocorticoids, cyclophosphamide, and rituximab. Limited data are available regarding prophylactic or preemptive treatment of CMV infection in patients with rheumatic diseases. In this article the authors present two cases of rheumatic conditions complicated by CMV infection. The first case describes a patient with eosinophilic granulomatosis with polyangiitis, previously treated with glucocorticoids and cyclophosphamide, who developed CMV colitis with bowel perforation. The second case involves a woman with systemic lupus erythematosus who was diagnosed with CMV meningitis. Both cases reinforce the importance of establishing guidelines for surveillance and prophylaxis of CMV infection in these patients.

Pathogen genome sequencing during epidemics enhances our ability to identify and understand suspected clusters and investigate their relationships. Here, we combine genomic and epidemiological data of the 2022 mpox outbreak to better understand early viral spread, diversification and transmission dynamics. By sequencing 52% of the confirmed cases in Portugal, we identified the mpox virus sublineages with the highest impact on case numbers and fitted them into a global context, finding evidence that several international sublineages probably emerged or spread early in Portugal. We estimated a 62% infection reporting rate and that 1.3% of the population of men who have sex with men in Portugal were infected. We infer the critical role played by sexual networks and superspreader gatherings, such as sauna attendance, in the dissemination of mpox virus. Overall, our findings highlight genomic epidemiology as a tool for the real-time monitoring and control of mpox epidemics, and can guide future vaccine policy in a highly susceptible population.

BACKGROUND: Integrase strand transfer inhibitor-based regimens are recommended for first-line therapy in human immunodeficiency virus type 2 (HIV-2). Nonetheless, dolutegravir (DTG) clinical trial data are lacking. METHODS: We conducted a phase 2, single-arm, open-label trial to evaluate the safety and efficacy of a triple therapy regimen that included DTG in persons with HIV-2 (PWHIV-2) in Portugal. Treatment-naive adults receive DTG in combination with 2 nucleoside reverse transcriptase inhibitors (NRTIs). Treatment efficacy was evaluated by the proportion of patients who achieved a plasma viral load (pVL) <40 copies/mL and/or by the change from baseline in CD4+ T-cell count and in CD4/CD8 ratio at week 48. RESULTS: A total of 30 patients were enrolled (22 women; median age, 55 years). At baseline, 17 (56.7%) individuals were viremic (median, pVL 190 copies/mL; interquartile range [IQR], 99-445). The median CD4 count was 438 cells/µL (IQR, 335-605), and the CD4/CD8 ratio was 0.8. Three patients discontinued the study. At week 48, all participants (27) had pVL <40 copies/mL. No virological failures were observed. Mean changes in CD4 count and CD4/CD8 ratio at week 48 were 95.59 cells/µL (95% confidence interval [CI], 28-163) and 0.32 (95% CI, .19 to .46). The most common drug-related adverse events were headache and nausea. One participant discontinued due to central nervous system symptoms. No serious adverse events were reported. CONCLUSIONS: DTG plus 2 NRTIs is safe and effective as first-line treatment for PWHIV-2 with a tolerability profile previously known. No virological failures were observed that suggest a high potency of DTG in HIV-2 as occurs in HIV-1. CLINICAL TRIALS REGISTRATION: M NCT03224338.

BACKGROUND: For people with HIV and CD4+ counts >500 cells/mm3, early initiation of antiretroviral therapy (ART) reduces serious AIDS and serious non-AIDS (SNA) risk compared with deferral of treatment until CD4+ counts are <350 cells/mm3. Whether excess risk of AIDS and SNA persists once ART is initiated for those who defer treatment is uncertain. METHODS: The Strategic Timing of AntiRetroviral Treatment (START) trial, as previously reported, randomly assigned 4684 ART-naive HIV-positive adults with CD4+ counts .500 cells/mm3 to immediate treatment initiation after random assignment (n = 2325) or deferred treatment (n= 2359). In 2015, a 57% lower risk of the primary end point (AIDS, SNA, or death) for the immediate group was reported, and the deferred group was offered ART. This article reports the follow-up that continued to December 31, 2021. Cox proportional-hazards models were used to compare hazard ratios for the primary end point from randomization through December 31, 2015, versus January 1, 2016, through December 31, 2021. RESULTS: Through December 31, 2015, approximately 7 months after the cutoff date from the previous report, the median CD4+ count was 648 and 460 cells/mm3 in the immediate and deferred groups, respectively, at treatment initiation. The percentage of follow-up time spent taking ART was 95% and 36% for the immediate and deferred groups, respectively, and the time-averaged CD4+ difference was 199 cells/mm3. After January 1, 2016, the percentage of follow-up time on treatment was 97.2% and 94.1% for the immediate and deferred groups, respectively, and the CD4+ count difference was 155 cells/mm3. After January 1, 2016, a total of 89 immediate and 113 deferred group participants experienced a primary end point (hazard ratio of 0.79 [95% confidence interval, 0.60 to 1.04] versus hazard ratio of 0.47 [95% confidence interval, 0.34 to 0.65; P<0.001]) before 2016 (P=0.02 for hazard ratio difference). CONCLUSIONS: Among adults with CD4+ counts >500 cells/mm3, excess risk of AIDS and SNA associated with delaying treatment initiation was diminished after ART initiation, but persistent excess risk remained.

RESUMO
Coronavirus disease 2019 (COVID-19) is a pandemic infection caused by the newly discovered severe acute respiratory syndrome coronavirus 2. Remdesivir (RDV) and corticosteroids are used mainly in COVID-19 patients with acute respiratory failure. The main objective of the study was to assess the effectiveness of remdesivir with and without corticosteroids in the treatment of COVID-19 patients. We conducted a prospective observational study, including adult patients consecutively hospitalized with confirmed COVID-19 and acute respiratory failure. Patients were divided according to treatment strategy: RDV alone versus RDV with corticosteroids. The primary outcome was the time to recovery in both treatment groups. We included 374 COVID-19 adult patients, 184 were treated with RDV, and 190 were treated with RDV and corticosteroid. Patients in the RDV group had a shorter time to recovery in comparison with patients in the RDV plus corticosteroids group at 28 days after admission [11 vs. 16 days (95% confidence Interval 9.7-12.8; 14.9-17.1; p = .016)]. Patients treated with RDV alone had a shorter length of hospital stay. The use of corticosteroids as adjunctive therapy of RDV was not associated with improvement in mortality of COVID-19 patients.

Campylobacter fetus, a bacteria of the Campylobacter genus that are a group of bacteria known to cause intestinal infections, is a particular microbial agent due to its most common presentation being as a non-intestinal systemic infection and rarely as a focal infection, most frequently cellulitis. C. fetus's main reservoirs are cattle and sheep. Humans are usually infected by consuming raw milk and/or meat. Infection in humans is rare and generally related to immune deficiencies, malignancy, chronic liver disease, diabetes mellitus and elderly age, among other factors. Diagnosis is usually achieved by blood cultures due to the lack of focalized signs/symptoms and the pathogen's endovascular tropism. The authors present a case of cellulitis due to Campylobacter fetus, a microbial agent that affects susceptible patients with a mortality rate of up to 14%. We aim to emphasize the importance of potential bacterial seeding sites secondary to bacteremia given the agent tropism for vascular tissue. The medical diagnosis was performed by the identification of bacteria in blood cultures. Campylobacter spp. infections are more frequently related to undercooked poultry or meat, but in this case, the consumption of fresh cheese was considered the most likely source of infection. A literature review showed that, in patients with previous antibiotic cycles, a combination of carbapenem and gentamicin had better outcomes and lower relapse rates. Due to typical surface antigenic variation, immune control may not be attainable and may account for relapsing infections, even after appropriate therapy. The duration of treatment has yet to be well established. Based on other reported cases, we considered a four-week treatment to be sufficient, given clinical improvement and absence of recurrence in the follow-up time.
RESUMO
OBJECTIVES: Our objective was to determine whether antiretroviral drugs (ARVs) were used according to the European AIDS Clinical Society (EACS) guidelines for people with HIV/hepatitis C virus (HCV) coinfection treated with direct-acting antivirals (DAAs) between 30 November 2014 and 31 December 2019 in the pan-European EuroSIDA study. METHODS: At each publication date of the EACS guidelines, plus 3 and 6 months, we calculated the number of people receiving DAAs with potential and actual ARV contraindications ('red shading' in the EACS guidelines). We used logistic regression to investigate factors associated with using contraindicated ARVs. RESULTS: Among 1406 people starting DAAs, the median age was 51 years, 75% were male, 57% reported injected drug use as an HIV risk, and 76% were from western Europe. Of 1624 treatment episodes, 609 (37.5%) occurred while the patient was receiving ARVs with potential contraindications; among them, 38 (6.2%; 95% confidence interval [CI] 4.3-8.2) involved a contraindicated ARV (18 non-nucleoside reverse transcriptase inhibitors), 16 involved protease inhibitors, and four involved integrase strand transfer inhibitors. The adjusted odds of receiving a contraindicated ARV were higher (3.25; 95% CI 1.40-7.57) among participants from east/central east Europe (vs. south) and lower (0.22; 95% CI 0.08-0.65) for 2015-2018 guidelines (vs. 2014). In total, 29 of the 32 (90.6%) patients receiving a contraindicated ARV and 441 of the 461 (95.7%) with potential ARV contraindications experienced a sustained virological response ≥12 weeks after stopping treatment (SVR12; p = 0.55). CONCLUSION: In this large heterogenous European cohort, more than one-third of people with HIV/HCV coinfection received DAAs with potential ARV contraindications, but few received a contraindicated ARV. Use of contraindicated ARVs declined over time, corresponding to the increased availability of ARV therapy regimens without interactions with DAA across Europe. Participants who received a contraindicated DAA and ARV combination still had a high rate of SVR12.

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 (nâ¯=â¯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.

Objective: 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.
RESUMO
INTRODUCTION: Although raltegravir has been available since 2007, data are lacking on the Portuguese population living with HIV who initiated this antiretroviral therapy. Hence, this study aimed to characterize the patients who initiated raltegravir-based regimens between January 2015 and December 2017, on sociodemographics, clinical features, and treatment satisfaction. MATERIAL AND METHODS: Observational, retrospective, multicentre study conducted at 11 reference sites. Sociodemographic and clinical data were collected retrospectively from hospital medical records. For participants continuing raltegravir at study inclusion, the HIV Treatment Satisfaction Questionnaire was administered to assess satisfaction with raltegravir-based therapy. Descriptive statistics were performed. Treatment-naïve and treatment-experienced subgroups were compared for demographic and clinical variables. RESULTS: A total of 302 patients were included; mostly men (69.5%) with a mean age of 49 years old. Approximately half of the patients had at least one non-AIDS-related comorbidity at baseline (53.3%), such as hypercholesterolemia, arterial hypertension, diabetes mellitus, and depression. Moreover, 52.3% were treatment-experienced patients with up to two treatments prior to raltegravir. Across the study time points, there was a reduction in the viral load and improvement in CD4 counts in both the treatment-naïve and treatment-experienced subgroups. Continuing users of raltegravir reported high treatment satisfaction (55.4 ± 7.2 points). CONCLUSION: Raltegravir-based regimens seem like a valid therapeutic option in heterogeneous populations of HIV-infected patients, in patients with previous ART experience and as part of first-line therapeutic options alongside with the latest generation of drugs from its class.
Introdução: Apesar de o raltegravir estar disponível desde 2007, os dados na população portuguesa com VIH que iniciou esta terapêutica antirretroviral são escassos. Deste modo, este estudo teve por objetivo caracterizar os doentes que iniciaram um regime terapêutico baseado em raltegravir entre janeiro de 2015 e dezembro de 2017, relativamente a dados sociodemográficos, características clínicas e satisfação com o tratamento. Material e Métodos: Estudo observacional, retrospetivo, multicêntrico conduzido em 11 centros de referência. Os dados sociodemográficos e clínicos foram recolhidos retrospetivamente nos processos clínicos. Os participantes que continuaram o regime com raltegravir após a inclusão no estudo preencheram o HIV Treatment Satisfaction Questionnaire para avaliar a satisfação com a terapêutica. Foram efetuadas análises de estatística descritiva e comparações para as variáveis sociodemográficas e clínicas nos subgrupos de doentes naïve de tratamento e de doentes com experiência terapêutica. Resultados: Foram incluídos 302 doentes, maioritariamente do sexo masculino (69,5%) com idade média de 49 anos. Aproximadamente metade dos doentes tinha pelo menos uma comorbilidade não relacionada com SIDA no início do estudo (53,3%), tais como hipercolesterolemia, hipertensão arterial, diabetes mellitus ou depressão. Adicionalmente, 52,3% eram doentes com experiência terapêutica com até dois tratamentos anteriores ao raltegravir. Ao longo do estudo verificou-se uma redução na carga viral e uma melhoria nas contagens de CD4 em ambos os subgrupos de doentes (doentes naïve de tratamento e doentes com experiência terapêutica). Os doentes com uso continuado de raltegravir reportaram uma elevada satisfação com o tratamento (55,4 ± 7,2 pontos). Conclusão: Os regimes terapêuticos baseados em raltegravir parecem ser uma opção terapêutica válida em populações heterogéneas de doentes infetados com VIH, em doentes com experiência em ART e como tratamento de primeira linha, em paralelo com outras terapêuticas de última geração.

Chronic hepatitis B (CHB) is a potentially life-threatening and prevalent disease worldwide. Far from attaining the ultimate treatment goal, hepatitis B virus (HBV) infection eradication, the two current therapeutic options aim to prevent progression to end-stage liver disease, maintaining long-term suppression of HBV replication. Pegylated interferon-α (PEG-INFα) is often poorly tolerated and disregarded considering the orally administered nucleos(t)ide analogues. However, PEG-INFα may achieve similar treatment endpoints with a finite course of treatment. We report a case of PEG-INFα-treated CHB that attained sustained off-treatment virological response with only 16 weeks of treatment, with loss of both HBeAg and HBsAg (this latter the optimal treatment endpoint).
RESUMO
BACKGROUND: Following the introduction of direct-acting antiviral therapy in 2013, WHO launched the first Global Health Sector Strategy on Viral Hepatitis. We describe a hepatitis C virus (HCV) cascade of care in people with HIV (PWH) across Europe in terms of reaching the WHO elimination targets of diagnosing 90% and treating 80% of HCV-infected individuals. METHODS: HIV/HCV-coinfected participants in the EuroSIDA cohort under prospective follow-up at October 1, 2019, were described using a nine-stage cascade of care. Care cascades were constructed across Europe, on a regional (nâ=â5) and country (nâ=â21) level. RESULTS: Of 4773 anti-HCV positive PWH, 4446 [93.1%, 95% confidence interval (CI) 92.4-93.9)] were ever tested for HCV RNA, and 19.0% (95% CI 16.4-21.6) were currently HCV RNA positive, with the highest prevalence in Eastern and Central-Eastern Europe (33.7 and 29.6%, respectively). In Eastern Europe, 78.1% of the estimated number of chronic infections have been diagnosed, whereas this proportion was above 95% in the other four regions. Overall, 3116 persons have ever started treatment (72.5% of the ever chronically infected, 95% CI 70.9-74.0) and 2404 individuals (55.9% of the ever chronically infected, 95% CI 53.9-57.9) were cured. Cure proportion ranged from 11.2% in Belarus to 87.2% in Austria. CONCLUSION: In all regions except Eastern Europe, more than 90% of the study participants have been tested for HCV-RNA. In Southern and Central-Western regions, more than 80% ever chronically HCV-infected PWH received treatment. The proportion with cured HCV infection did not exceed 80% in any region, with significant heterogeneity between countries. SUMMARY: In a pan-European cohort of PWH, all regions except Eastern Europe achieved the WHO target of diagnosing 90% of chronic HCV infections, while the target of treating 80% of eligible persons was achieved in none of the five regions.
