ABSTRACT Background: Women living with human immunodeficiency virus (HIV) (WLWH) are more likely to be infected with the oncogenic human papillomavirus (HPV). We assessed the prevalence of high-risk (HR) (16/18/31/33/35/39/45/51/52/56/58/59/68/73/82), probable high-risk (pHR) (26/53/66), and low-risk (LR) (6/11/40/42/43/44/54/61/70) HPV types and their associated risk factors. Methods: This cross-sectional study of WLWH aged 18-64 years included one laboratory and eight HIV-specialty healthcare facilities in the pilot network. Descriptive statistics were used to assess sociodemographic and behavioral characteristics. Adjusted analyses were conducted to evaluate risk factors associated with HR and/or pHR HPV infection in WLWH. Results: From May/2021 to May/2022, 1,914 (92.5%) WLWH participated in the pilot study and had valid HPV-DNA results of self-collected vaginal samples. The median age of the participants was 45 years, 60.1% had ≥ 9 years of schooling, 80.5% were ≤ 18 years at first sexual intercourse, and 51.7% had > 4 sexual partners throughout life. The prevalence of any HPV type, HR HPV, pHR HPV, and LR HPV was 65.8%, 49.6%, 16.7%, and 40.0%, respectively. Age was inversely associated with pHR and/or HR-HPV (p < 0.001), and education level was inversely associated with HR-HPV (p = 0.003) types. Any HR or pHR was associated with being single (p = 0.029) and exchanging sex for drugs (p = 0.037). Conclusions: The prevalence of HPV, especially HR HPV, among WLWH is high in Brazil, highlighting the need for HPV screening in this population. Self-collection of vaginal samples is an important strategy for increasing testing access.

Objective: To analyze the seroprevalence of SARS-CoV-2 and the association of sociodemographic and clinical aspects in the state of Espírito Santo, Brazil. Methods: Serial cross-sectional study carried out in four phases, using households as the unit of analysis, from May to June 2020. 11 municipalities were surveyed, with a sample of 4,500 households in each phase. Results: the prevalence ranged from 2.1% (95%CI: 1.7;2.5) on May 10 (first stage) to 9.6% (95%CI: 8.8;10.4), on June 21 (fourth stage). In the metropolitan region of Greater Vitória, the prevalences were 2.7% (95%CI: 2.2;3.3), in the first, and 11.5% (95%CI: 10.5;12.6) in the fourth stage; within the state it ranged from 0.4% (95%CI: 0.1;0.9) to 4.4% (95%CI: 3.2;5.5) between the two stages. Conclusion: The increase in SARS-CoV-2 seroprevalence observed in the fourth phase highlighted the high transmission of the virus, supporting the management of the pandemic.

Objectives: to estimate the prevalence of SARS-CoV-2 infection in residents of the Greater Vitória region living in subnormal and non-subnormal agglomerations; and, compare sociodemographic and clinical characteristics of total residents (infected and not infected with SARS-CoV-2), among these clusters. Method: Population-based prevalence study, through serological testing carried out in 2020, with a study unit in households in Greater Vitória, grouped into census tracts classified as sub-normal clusters (AGSN) and non-sub-normal clusters (AGNSN ). The two groups were compared in terms of prevalence and associated factors. The significance level adopted was 5%. Results: The prevalence found in the AGSN was 12.05% (95% CI from 9.59 to 14.50%), and in the AGNSN group it was 10.23% (95% CI from 7.97% to 12.50% ) this difference was not statistically significant (p = 0.273). Comparing the sociodemographic characteristics, more people who declare themselves to be of mixed race were found in the SGNA, a higher percentage of illiterates and people with only elementary education, greater number of residents per household, longer stay in public transport, sharing a bathroom with another household , fewer bedrooms per residence and higher frequency of irregular water supply when compared to AGNSN(Plt;0.05). Conclusions: The epidemiological characteristics of the SNGA residents show the social inequalities that can hinder control measures in a pandemic situation.

Objetivos: estimar prevalência de infecção pelo SARS-CoV-2 em residentes na região da Grande Vitória moradores de aglomerados subnormais e não subnormais; e, comparar características sociodemográficas e clínicas dos residentes totais (infectados e não infectados com o SARS-CoV-2), entre esses aglomerados.nbsp; Método: Estudo de prevalência de base populacional, por meio de teste sorológico realizado em 2020, com unidade de estudo em domicílios da Grande Vitória, agrupados em setores censitários classificados como Aglomerados sub-normais (AGSN) e os Aglomerados não sub-normais (AGNSN). Os dois grupos foram comparados quanto a prevalência e fatores associados. O nível de significância adotado foi de 5%. Resultados: A prevalência encontrada no AGSN foi 12,05% (IC 95% de 9,59 a 14,50%), e no grupo AGNSN foi 10,23% (IC 95% de 7,97% a 12,50%) esta diferença não foi estatisticamente significante (p = 0,273). Comparando-se as características sociodemográficas foram encontradas nos AGSN mais pessoas que se autodeclaram da raça cor parda, percentual maior de analfabetos e pessoas apenas com ensino fundamental, maior número de moradores por domicílio, maior permanência em transporte coletivo, compartilhamento de banheiro com outro domicílio, menos dormitórios por residência e maior frequência de abastecimento irregular de água quando comparadas aos AGNSN(Plt;0,05). Conclusões: As características epidemiológicas dos moradores de AGSN evidenciam as desigualdades sociais que podem dificultar as medidas de controle em uma situação de pandemia.

Objective: To Analyze self-reported sociodemographic and clinical aspects among individuals aged 2 to 22 years and possible associations with SARS-CoV-2 infection in Espírito Santo. Methods: Serial cross-sectional population-based study carried out from May to June 2020. The percentage of positivity for COVID-19 was evaluated by serological test, and the associated factors by Pearson's chi-square test (significance level of 5%). Results: Among 1,693 individuals aged 2 to 22 years, 6,1% tested positive for COVID-19 and, among these, 35.5% did not present any symptoms. Differences were identified between positive and negative regarding the number of symptoms (p-value=0.001). Cough was reported by 40.4% of positive individuals. Only 14.3% sought health care, with 29.8% among the positive and 13.3% among the negative (p-value=0.001). Conclusion: The percentage of asymptomatic patients can impact the transmission chain of COVID-19 in schools and boost outbreaks of the disease in schools.

Abstract Chronic hepatitis B is an important health problem that can progress to cirrhosis and complications such as hepatocellular carcinoma. There is approximately 290 million of people with chronic hepatitis B virus (HBV) infection worldwide, however only 10% of patients are currently identified.Most part of Brazil is considered of low prevalence of HBV infection but there are some regions with higher frequency of carriers. Unfortunately, many infected patients are not yet identified nor evaluated for treatment.The Brazilian Society of Infectious Diseases (SBI) and the Brazilian Society of Hepatology worked together to elaborate a guideline for diagnosis and treatment of hepatitis B. The document includes information regarding the population to be tested, diagnostic tools, indications of treatment, therapeutic schemes and also how to handle HBV infection in specific situations (pregnancy, children, immunosuppression, etc).Delta infection is also part of the guideline, since it is an important infection in some parts of the country.

RESUMO CONTEXTO: A infecção pelo vírus da hepatite C (HCV) é uma das principais causas de hepatite C crônica e provoca implicações graves para pacientes, familiares e sistema de saúde. OBJETIVO: Os objetivos deste estudo foram: analisar a gravidade da fibrose hepática, comorbidades e complicações da hepatite C; examinar a qualidade de vida relacionada à saúde (QVRS), a perda de produtividade e o uso de recursos e custos no sistema público por pacientes brasileiros com hepatite C crônica, genótipo tipo 1. MÉTODOS: Foi realizado um estudo transversal, multicêntrico em pacientes com hepatite C crônica genótipo-1 para avaliar a carga da doença no sistema público de saúde brasileiro entre novembro de 2014 e março de 2015. Os pacientes foram submetidos a uma elastografia hepática transitória (FibroScan) para avaliar a fibrose e a uma entrevista composta por um questionário desenvolvido para o estudo e cinco questionários padronizados: EQ-5D-3L, HCV-PRO, e WPAI:HepC. RESULTADOS: Foram recrutados 313 pacientes. A amostra foi composta predominantemente por mulheres (50,8%), caucasianos/brancos (55,9%) e indivíduos empregados (39,9%). A média de idade foi 56 (DP=10,4) anos. Em média, os pacientes com HCV esperaram 40,6 (DP=49,6) meses entre o diagnóstico e o primeiro tratamento. Ademais, 42,8% dos pacientes que realizaram o FibroScan tinham cirrose; a comorbidade mais frequente foi doença cardiovascular (62,6%) e a complicação mais comum as varizes esofágicas (54,5%). Os resultados também mostraram que “dor e desconforto” foi a dimensão de QVRS mais afetada (55,0% dos pacientes relataram alguns problemas) e que a média do escore do HCV-PRO foi 69,1 (DP=24,2). Em relação à perda de produtividade, o componente do WPAI:HepC mais afetado foi atividade diária (23,5%) e entre os pacientes empregados, presenteísmo foi mais frequente do que absenteísmo (18,5% vs 6,5%). Os custos diretos médicos totais com essa amostra foi de 12.305,72USD por paciente em um período de dois anos; o tratamento medicamentoso representou 95% desse total. CONCLUSÃO Esse estudo mostrou a maioria dos pacientes possui cirrose, apresenta alta prevalência de doenças cardiometabolicas e varizes esofágicas, QVRS reduzida principalmente em termos de dor/desconforto e dano na produtividade, especialmente presenteísmo. Adicionalmente, nós demonstramos que o HCV impõe uma carga econômica no sistema de saúde brasileiro e que os medicamentos correspondem à maioria dos custos.

ABSTRACT BACKGROUND: Infection by hepatitis C virus is one of the leading causes of chronic hepatitis C and cause severe burden for patients, families and the health care system. OBJECTIVE: The aims of this research were to assess the severity of liver fibrosis, comorbidities and complications of hepatitis C virus; to examine health-related quality of life (HRQoL), productivity loss and resource use and costs in a sample of Brazilian chronic hepatitis C, genotype 1, patients. METHODS: This was a cross-sectional multicenter study performed in genotype-1 chronic hepatitis C patients to assess disease burden in the Brazilian public health care system between November 2014 and March 2015. Patients were submitted to a liver transient elastography (FibroScan) to assess liver fibrosis and answered an interview composed by a questionnaire specifically developed for the study and three standardized questionnaires: EQ-5D-3L, HCV-PRO and WPAI:HepC. RESULTS: There were 313 subjects enrolled, with predominance of women (50.8%), caucasian/white (55.9%) and employed individuals (39.9%). Mean age was 56 (SD=10.4) years old. Moreover, 42.8% of patients who underwent FibroScan were cirrhotic; the most frequent comorbidity was cardiovascular disease (62.6%) and the most frequent complication was esophageal varices (54.5%). The results also showed that “pain and discomfort” was the most affected HRQoL dimension (55.0% of patients reported some problems) and that the mean HCV-PRO overall score was 69.1 (SD=24.2). Regarding productivity loss, the most affected WPAI:HepC component was daily activity (23.5%) and among employed patients, presenteeism was more frequent than absenteeism (18.5% vs 6.5%). The direct medical costs in this chronic hepatitis C sample was 12,305.72USD per patient in the 2 years study period; drug treatment costs represented 95.9% of this total. CONCLUSION: This study showed that most patients are cirrhotic, present high prevalence of cardiometabolic diseases and esophageal varices, reduced HRQoL mainly in terms of pain/discomfort, and work productivity impairment, especially presenteeism. Additionally, we demonstrated that hepatitis C virus imposes an economic burden on Brazilian Health Care System and that most of this cost is due to drug treatment.

OBJECTIVE: To evaluate the effectiveness and safety of first-generation protease inhibitors for the treatment of genotype 1 hepatitis C virus-infected patients at Brazilian reference centers. METHODS: This multicenter cross-sectional study included hepatitis C virus genotype 1 monoinfected patients treated with Peg-interferon, ribavirin, and either boceprevir (n=158) or telaprevir (n=557) between July 2013 and April 2014 at 15 reference centers in Brazil. Demographic, clinical, virological, and adverse events data were collected during treatment and follow-up. RESULTS: Of the 715 patients, 59% had cirrhosis and 67.1% were treatment-experienced. Based on intention-to-treat analysis, the overall sustained viral response was 56.6%, with similar effectiveness in both groups (51.9% for boceprevir and 58% for telaprevir, p=0.190). Serious adverse events occurred in 44.2% of patients, and six deaths (0.8%) were recorded. Cirrhotic patients had lower sustained viral response rates than non-cirrhotic patients (46.9% vs. 70.6%, p<0.001) and a higher incidence of serious adverse events (50.7% vs. 34.8%, p<0.001). Multivariate analysis revealed that sustained viral response was associated with the absence of cirrhosis, viral recurrence after previous treatment, pretreatment platelet count greater than 100,000/mm3, and achievement of a rapid viral response. Female gender, age>65 years, diagnosis of cirrhosis, and abnormal hemoglobin levels/platelet counts prior to treatment were associated with serious adverse events. CONCLUSION: Although serious adverse events rates were higher in this infected population, sustained viral response rates were similar to those reported for other patient cohorts.

ABSTRACT Despite recent advances in therapy for chronic hepatitis C (CHC), the disease caused by genotype 3 virus (GEN3) is still considered a treatment challenge in certain patient subgroups. The aim of this retrospective study was to evaluate the effectiveness and safety of the peginterferon (Peg-IFN) and ribavirin (RBV) combination treatment for GEN3/CHC patients, and to evaluate sustained virological response (SVR) indicators and early treatment interruption due to serious adverse events (SAE). This was a retrospective observational study of GEN3/CHC patients, co-infected or not by HIV and treated with Peg-IFN/RBV in nine Brazilian healthcare centers. The study sample included 184 GEN3/CHC patients; 70 (38%) were co-infected with HIV. The overall SVR rate was 57.1% (95% CI 50-64). Among co-infected and mono-infected patients, the SVR rate was 51.4% (36/70) and 60.5% (69/114), respectively (p=0.241). Thirty-four (18.5%) patients experienced SAE and interrupted treatment. SVR was negatively associated with the use of Peg-IFN alpha 2b (PR 0.75; 95% CI 0.58-0.99; p=0.045) and to early treatment interruption due to SAE (PR 0.36; 95% CI 0.20-0.68; p=0.001). Early treatment interruption due to SAE was associated with age (PR 1.06; 95% CI 1.02-1.10; p<0.001) and occurrence of liver cirrhosis (PR 2.06; 95% CI 1.11-3.83; p=0.022). In conclusion, Peg-IFN/RBV might represent an adequate treatment option, mainly in young patients without advanced liver disease or when the use of direct-action drugs is limited to specific patient groups.

Introduction: in Brazil, chronic hepatitis C in patients coinfected with the human immunodeficiency virus (HIV) is treated with pegylated interferon (Peg-IFN) and ribavirin (RBV). However, few studies have evaluated the effectiveness of this treatment in this particular population. The identification of the factors that predict sustained virological response (SVR) under current clinical practice would enable clinicians to more accurately estimate the probability of achieving an SVR and therefore utilize the appropriate therapeutics, especially in the era of direct-acting antiviral (DAA) agents.Aims: the primary aim of our study was to determine the SVR rate under current clinical practice. The secondary aims were as follows: (1) to determine the factors before and during treatment that predict SVR; and (2) to identify the causes of treatment interruption.Methods:within a cohort of HIV/hepatitis C virus (HCV)-coinfected patients in Brazil, we performed a retrospective analysis of those individuals treated with Peg-IFN and RBV.Results:among the 382 analyzed patients, SVR was observed in 118 [30.9% (95% confidence interval (CI): 26.3-35.8)], which included 25.9% (75/289) of the patients with genotypes 1 and 4 and 48.2% (41/85) of those with genotypes 2 and 3. After multivariate analyses the independent positive predictors for SVR after treatment for chronic hepatitis C with PegIFN and RBV were: absence of an AIDS-defining illness (p= 0.001), HCV viral load lower than 600,000 IU/mL at the onset of treatment (p= 0.003), higher liver enzyme levels (p= 0.039) at baseline, infection with genotypes 2 or 3 (p= 0.003), and no transient treatment interruption (p= 0.001). The treatment was interrupted in 25.6% (98/382) of the patients because of adverse events (11.3%, 43/382), virologic failure (7.8%, 30/382), and dropout (6.5%, 43/382). The main adverse events were cytopenia and psychiatric disorders.Conclusions:in our Brazilian case series, the SVR rate under current clinical practice conditions was similar to that reported in other studies. There was a correlation between an SVR and being infected by genotypes 2 and 3, low viral load, high ALT levels at the onset of treatment, and absence of an AIDS-defining illness. Cytopenia and psychiatric disorders were the major causes of treatment interruption. Efforts should be focused on optimizing management of side effects and counseling to improve adherence and to keep patients on treatment.

We designed a retrospective cohort study to identify factors associated with HIV-1 related lipodystrophy at a tertiary HIV-care center in Vitória, ES, Brazil. Inclusion criteria were documented HIV diagnosis, anti-retroviral therapy and age above 17 years. Highly active antiretroviral therapy (HAART) was initially the exposure variable, but a second analysis was also performed, as a nested case-control, based on the presence or absence of lipodystrophy. Use of protease inhibitors (PI) was associated with an increase in serum triglycerides (243.7 ± 189 mg/dL vs. 172.7 ± 131 mg/dL, p = 0.015), but not of total cholesterol (TC) or HDL fraction levels. Non-nucleoside reverse transcriptase inhibitors (NNRTI) were associated with an increase in serum TC (180.6 ± 46.8 mg/dL versus 162.4 ± 41.4 mg/dL; p= 0.018) and an increase in HDL cholesterol (47.3 ± 13.8 mg/dL versus 23.3 ± 24.3 mg/dL; p < 0.001), with no significant effect on triglyceride levels. Lipodystrophy was diagnosed in 59.3% of the patients, but exposure to PI versus NNRTI did not affect the frequency of this disorder (43.4% versus 37.2%; p = 0.68). Serum TC, but not HDL cholesterol or triglyceride levels, was higher among the lipodystrophy cases (183.8 ±47.5 mg/dL versus 162.1 ±35.7; p=0.006). Among the controls (patients without lipodystrophy), HDL cholesterol (45.3 ±14.4 mg/dL vs. 27.1 ±26.3; p=0.001)and triglyceride levels (178.3 ±146.3 mg/dL vs. 126.3 ±126.9; p=0.013) also increased, but not TC. In conclusion, lipodystrophy was highly prevalent in our series. Lipid disorders were also frequent and apparently were related to lipodystrophy, except for triglyceride levels.
