ABSTRACT Objective: Diabetes mellitus (DM) has a high healthcare system cost worldwide. Educational strategies are important to improve self-care and control this disease. This study aimed to evaluate satisfaction and clinical efficacy of a Short Message Service (SMS) educational intervention in self-care and nutrition at a Brazilian university hospital. Materials and methods: We conducted a trial of educational intervention and assigned eligible patients with DM to either receive weekly educational SMS for 6 months (intervention group [IG]) or no SMS at all (control group). A satisfaction questionnaire was applied before and after the intervention in both groups. Laboratory (fasting glucose, hemoglobin [Hb] A1c, total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein) and clinical (blood pressure) data were also collected. Data were analyzed using nonparametric tests with the Statistical Package for the Social Sciences. Results: We included 128 patients (64 in each group). Responses to the satisfaction questionnaire with self-care and healthcare professionals from 112 patients revealed an improvement in the perception of receiving information regarding helpful eating habits and in healthy eating behavior and an improvement in satisfaction with their diabetes care in the IG. In the post-intervention period, improved systolic blood pressure and HbA1c levels were observed in the IG as illustrated by delta % (post-intervention minus pre-intervention data divided by pre-intervention data multiplied by 100) reductions of 2.3% and 3.9%, respectively Conclusion: SMS intervention was useful as an educational tool for improving satisfaction and glycemic and blood pressure control of patients with DM observed at a Brazilian university hospital.

ABSTRACT Objective The consequences of sleep deprivation in type 1 diabetes (T1D) patients are poorly understood. Our aim was to determine how sleep disorders influence lipid profile and insulin sensitivity in T1D patients. Materials and methods This was a cross-sectional study at a public university hospital. Demographic information and medical histories were obtained during regular scheduled visit of T1D patients to the outpatient clinic. Insulin sensitivity was obtained using the estimated glucose disposal rate (eGDR) formula. Sleep quality was assessed using the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Berlin Questionnaire. Results The adult participants (n = 66, 62% women) had a median age of 28.0 years (interquartile range 21.8-33.0). Six patients (9%) had metabolic syndrome according to the International Diabetes Federation criteria. Thirty patients (46%) were considered poor sleepers according to the Pittsburgh Sleep Quality Index. The LDL-c and total cholesterol levels of poor sleepers were higher than those of good sleepers (103 v. 81; p = 0.003 and 178.0 v. 159.5 mg/dL; p = 0.009, respectively). Three patients (4%) were at high risk of obstructive sleep apnea syndrome (OSAS) according to the Berlin Questionnaire. The eGDR was lower in the group of patients with high probability of having OSAS (6.0 v. 9.1 mg.kg-1.min-1;p = .03). Conclusions Poor subjective quality of sleep and higher risk of OSAS were correlated with a worsened lipid profile and decreased insulin sensitivity, respectively. Therefore, T1D patients with sleep disturbances might have an increased cardiovascular risk in the future.

Abstract: En | Text: En | PDF: En

OBJECTIVES: This study aimed to evaluate the potential relationship between oxidative stress, dietary intake, and serum levels of antioxidants in patients with a complete hydatidiform mole (CHM) compared with controls. METHODS: This was an observational cross-sectional study conducted in Rio de Janeiro, Brazil. A total of 140 women were enrolled in this study and divided into four groups: 43 patients with CHM, 33 women who had had an abortion, 32 healthy pregnant women, and 32 healthy non-pregnant women. All participants underwent blood sampling, assessment using a semiquantitative food frequency questionnaire, and anthropometric measurement. Blood samples were collected after overnight fasting (10-12 h). Vitamin levels (A, C, and E) were determined by ultra-performance liquid chromatography, and gamma-glutamyl transferase levels were assessed using an automated quantitative analysis system (Dimension®, Siemens). RESULTS: Although all groups showed sufficient serum vitamin A and E levels, the participants had inadequate dietary intake of these vitamins. Conversely, all groups had an insufficient serum level of vitamin C, despite adequate intake. The gamma-glutamyl transferase values did not differ significantly among the groups. However, elevated serum levels of this enzyme were observed in several patients. CONCLUSIONS: All groups exhibited high levels of oxidative stress, as evaluated by gamma-glutamyl transferase levels, and had inadequate intake of antioxidant vitamins. Therefore, the high exposure to oxidative stress found in our study, even in healthy pregnant and non-pregnant women, may increase the incidence of CHM in this region.

ABSTRACT The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.

Resumo Objetivo: avaliar a concordância entre os métodos de estimativa de estatura com a estatura aferida de idosos atendidos em ambulatório de nutrição. Método: foram avaliados 43 idosos, de ambos os sexos, durante as consultas de nutrição, tendo sido coletados dados sociodemográficos dos prontuários e aferidas a estatura, altura do joelho, envergadura e semienvergadura dos braços. A análise estatística dos dados foi feita pelo teste de Bland-Altman para avaliar a concordância entre as estaturas estimadas pelas fórmulas preditivas e a estatura aferida. Resultados: os valores encontrados foram: estatura aferida em metros 1,53 (±0,08), estatura estimada pela envergadura 1,60 (±0,10), pela semienvergadura 1,61 (±0,11) e pela atura do joelho 1,56 (±0,10). De acordo com o gráfico de Bland-Altman a estatura estimada pela altura do joelho apresentou melhor concordância com a estatura aferida. Conclusão: com os resultados encontrados neste trabalho, observamos que as fórmulas preditivas para estimativa de estatura em idosos, que utilizam envergadura e semienvergadura dos braços não apresentaram boa concordância com a estatura aferida. Já a altura do joelho, utilizando a fórmula de Chumlea, apresentou a melhor concordância com a estatura aferida e parece ser a uma boa maneira para estimar a estatura da população estudada.

Abstract Objective: to evaluate methods of elderly height estimation attended at the Nutrition ambulatory. Method: a total of 43 elderly individuals of both genders were evaluated during nutrition consultations. Sociodemographic data were collected from charts and height, knee height, arms wingspan and semi-span were measured. Statistical analysis were made through Bland-Altman test to evaluate concordance among statures estimated by predictive formulas and the height measured. Results: the values found were: height measured in meters 1.53 (±0.08), height estimated by the wingspan 1.60 (±0.10), by the semi-span 1.61 (±0.11) and by the knee height 1.56 (±0.10). According to the Bland-Altman graph, the height estimated by knee height showed a better agreement with the measured height. Conclusion: according to this study results, poor predictive formulas concordance in height estimation in elderly, using the measures: arms wingspan and semi-span with real stature measured were observed. Knee height, using Chumlea formula, presented the best concordance with measured stature and seems to be a good way for stature estimation at the studied population.

Abstract INTRODUCTION: Dengue is one of the most important mosquito-borne infections. Severe cases are more frequently observed in adults. However, in 2008, the State of Rio de Janeiro, Brazil, experienced a severe dengue epidemic that primarily affected children and caused many cases of dengue hemorrhagic fever (DHF) and death. METHODS: A cross-sectional analytical study was conducted to examine laboratory diagnosis and clinical epidemiologic factors for confirmed dengue cases in patients aged less than 16 years, from January to June 2008, at a municipal hospital in the City of Rio de Janeiro, Brazil. Variables associated with severe outcomes and P values less than .05 were evaluated by means of a logistic regression model. RESULTS: Of the 419 dengue cases studied, 296 were classified as DHF and 123 as classical dengue. Six patients who had DHF died. In multivariate analysis, some laboratory and clinical variables were independently associated with DHF: age 5 years or older (odds ratio [OR], 4.94; 95% confidence interval [CI], 1.30-18.71), abdominal pain (OR, 8.59; 95% CI, 3.17-23.27), hepatomegaly (OR, 15.87; 95% CI, 5.38-46.85), and positive tourniquet test (OR, 10.84; 95% CI, 3.96-29.71). Hypoalbuminemia occurred more frequently than hemoconcentration in DHF cases, and high aminotransferase levels were associated with severity. CONCLUSIONS: Age greater than 5 years, abdominal pain, painful hepatomegaly, and positive tourniquet test were predictors of DHF. The high frequency of hepatic impairment suggests that acetaminophen should be avoided in severe cases of dengue.

Resumo O tratamento da aids implica a utilização de diversos medicamentos que compõem a terapia antirretroviral, sendo o controle logístico monitorado por um sistema nacional informatizado de dispensação, o Sistema de Controle Logístico de Medicamentos (SICLOM). O objetivo foi investigar a utilização da terapia antirretroviral de pacientes de dois hospitais universitários no Estado do Rio de Janeiro a partir do SICLOM. Foi realizado um estudo seccional com coleta de dados sociodemográficos e de dispensação, a partir do SICLOM. A avaliação da posse para estimativa de pacientes não aderidos foi realizada através do indicador de proporção de dias cobertos (PDC). Foram incluídos 538 pacientes com cadastro ativo no SICLOM, maiores de 18 anos de ambos os sexos. O ARV mais utilizado em ambos os hospitais foi lamivudina, dentre 58 esquemas diferentes identificados. A maior parte dos pacientes utilizava esquemas classificados como de primeira linha de tratamento. Em média, a proporção de dias cobertos (posse) pelo tratamento foi 88% (± 0,16). A linha de tratamento mostrou associação estatística com a posse, sendo observado melhor PDC 91% (p < 0,001) para os esquemas resgate. Este estudo corroborou o SICLOM como uma boa fonte para conhecimento do perfil de utilização de ARV.

Abstract Treatment of AIDS involves the use of the cocktail of drugs that make up the antiretroviral therapy. Its logistic control is monitored by a computerized national system of dispensation, the Logistic Control System of Medication (SICLOM). This study aimed to investigate, by means of SICLOM data, the use of antiretroviral therapy in patients treated at two University Hospitals in the state of Rio de Janeiro. A cross-sectional study was conducted with sociodemographic and dispensation data collected from SICLOM. The evaluation of drug ownership was done by calculating the Proportion of Days Covered (PDC). Five hundred and thirty-eight patients of both genders with active registration in SICLOM and over 18 years of age were included. The ART most used in both hospitals was lamivudine, considering the total of 58 different schemes identified. The mean of possession of groups was 88% (± 0,16). The factor associated with possession of drugs was the ART scheme, with PDC of 91% (p<0,001) for rescue schemes. This study confirmed that SICLOM was a reliable source to establish the profile of the population assisted.

Resumo O termo de consentimento livre e esclarecido (TCLE) é documento onde se explicita o consentimento do participante, contendo todas as informações necessárias para que seja elucidada a pesquisa da qual se propõe participar. O objetivo deste trabalho foi avaliar o nível de compreensão do TCLE assinado por 146 voluntários, utilizando instrumento de coleta de dados autoaplicável. A média de idade foi 47,3 anos, com prevalência de participantes do gênero feminino (67,2%), ensino fundamental incompleto (53,4%) e sem assistência privada de saúde (93,2%). A média de acertos foi 53,1%. Não houve associação entre o percentual de acerto e as variáveis gênero, idade, escolaridade e tempo de resposta. Houve associação significativa entre levar a via do TCLE para casa e o percentual de acerto. O valor médio de acertos evidenciou a necessidade de novas medidas educativas, buscando aumentar a compreensão e a segurança dos participantes.

Abstract The informed consent form (ICF) is a document which explicitly confirms the consent of a participant in a research project, and should contain all necessary information clarifying the study in which the subject intends to participate. This study evaluates the level of comprehension of an ICF signed by 146 volunteers using a self-administered instrument. The average age of the sample was 47.29 years, and there was a prevalence of women (67.2%), incomplete primary education (53.4%) and no private health care (93.2%). The mean score of correct answers of 146 respondents was 53.1%. There was no association between the percentage of correct answers and the variables of gender, age, education and time of response. There was a significant association between taking the ICF home and the percentage of correct answers. The average value of correct answers found was not acceptable and educational measures must be implemented, seeking an increase in comprehension and the safety of participants.

RESUMO: Objetivo: Descrever a metodologia de um estudo sobre associações entre crescimento intrauterino restrito (CIUR) e prevalência de sobrepeso, obesidade e hipertensão arterial em escolares. Métodos: O estudo, conduzido em dois estágios, foi desenvolvido em 2 escolas municipais de Niterói (RJ) de junho a dezembro de 2010, sendo elegíveis todos os escolares de 6 a 14 anos. O primeiro estágio consistiu em um inquérito nutricional e de potenciais fatores de risco. Foram aplicados questionários aos responsáveis e adolescentes. Concomitantemente, foram selecionados os participantes de um estudo caso-controle, com casos prevalentes definidos como todos os escolares que apresentaram excesso de peso (Z-score de índice de massa corporal -IMC/idade/sexo > +1,00). O grupo controle consistiu em uma amostra aleatória da população de estudo do inquérito, o que permitiu o cálculo de razões de prevalências. Foram realizados bioimpedância elétrica, exames de sangue, ultrassonografia da carótida e entrevistas. As variáveis proxy de CIUR foram definidas a partir de informações sobre peso ao nascer (PN) e idade gestacional (IG). Adicionalmente, foram coletadas informações sobre os dois primeiros anos de vida dos escolares a partir de seus prontuários médicos. Resultado s: Entre os 1.040 escolares elegíveis, participaram do estudo 795 escolares (76,4%). A taxa de retorno do questionário enviado para os responsáveis foi de 85,1%. Para o estudo caso-controle, 62,5% (n = 363) dos selecionados participaram, resultando em uma razão caso:controle de 1:1,8. Foram localizados 55,8% (n = 444) dos prontuários, dos quais em 65,7% (n = 292) foram coletadas informações dos primeiros anos de vida. Conclusão: O presente estudo permitirá a análise de múltiplos desfechos e exposições relacionados ao CIUR e alterações metabólicas.

ABSTRACT: Objective: To describe the methodological features of a study on the association between restricted intrauterine growth and prevalence of overweight, obesity and hypertension in school aged children. Methods: The study was conducted in two stages in two public schools in Niterói (RJ), from June through December 2010. All students aged 6 to 14 years were eligible to participate. The first stage consisted of an interview to collect information on demographic variables, diet and other variables. A sample was selected for the second stage, in order to conduct an equivalent of a case-cohort study. There was an interval of about 15 days between the two stages. Cases were overweight students, defined as a Z-score for BMI/age/sex > +1.00 in the first stage. Controls were selected by using a random schedule in which the sample frame was the whole cohort. Bioelectrical impedance analysis, carotid ultrasound to measure intimal-medial thickness, blood measurements and interviews were obtained. Gestational age and weight at birth were used to define proxy variables of restricted intrauterine growth. Early health information was obtained from medical registers. Results: The study participation was 76.4% (n = 795) out of 1,040 eligible to participate). 85.1% of parent's questionnaires were returned. 62.5% of the eligible children participated in the case-control study (case: control ratio = 1:1.8). Early life health information was obtained from 292 children. Conclusion: The present study has the potential to provide important information about multiple outcomes and exposures related to restricted intrauterine growth and metabolic abnormalities.

Introduction: malnutrition is a common complication for cancer patients. The phase angle (PA), direct measurement of bioelectrical impedance analysis (BIA), has been considered a predictor of body cell mass and prognostic indicator. Cutoff points for phase angle (PA) associated with nutritional risk in cancer patients have not been determined yet. Objectives: assess the possibility of determining the cutoff point for PA to identify nutritional risk in pre-radiotherapy cancer patients. Methods: sample group: Patients from both genders diagnosed with cancer and sent for ambulatory radiotherapy. Variables studied: body mass index (BMI), percentage of weight loss (% WL), mid-arm circumference (MAC), triceps skinfold thickness (TST), mid-arm muscle circumference (MAMC), mid-arm muscle area (MAMA), score and categorical assessment obtained using the Patient-Generated Subjective Global Assessment (PG-SGA) form, PA and standardized phase angle (SPA). Kappa coefficient was used to test the degree of agreement between the diagnoses of nutritional risk obtained from several different methods of nutritional assessment. Cutoff points for the PA through anthropometric indicators and PG-SGA were determined by using Receiver Operating Characteristic (ROC) curves, and patient survival was analyzed with the Cox regression method. Results: the cutoff points with the greatest discriminatory power were those obtained from BMI (5.2) and the categorical assessment of PG-SGA (5.4). The diagnosis obtained using these cutoff points showed a significant association with risk of death for the patients in the sample group. Conclusion: we recommend using the cutoff point 5.2 for the PA as a criterion for identifying nutritional risk in pre-radiotherapy cancer patients.

Introducción: la desnutrición es una complicación frecuente en los pacientes con cáncer. El ángulo de fase (AF), medición directa del análisis de impedancia bioeléctrica (AIB), puede ser considerado un factor de predicción de la masa celular corporal e indicador de pronóstico. Los puntos de corte para el ángulo de fase (PA) que se asocian con el riesgo nutricional en pacientes con cáncer aún no han sido determinados. Objetivos: evaluar la posibilidad de determinar el punto de corte para el AF para identificar riesgo nutricional en pacientes con cáncer antes de la radioterapia. Métodos: grupo muestreado: pacientes de ambos sexos con diagnóstico de cáncer y enviados para radioterapia ambulatoria. Variables estudiadas: índice de masa corpórea (IMC), porcentaje de pérdida de peso (% PP), circunferencia del brazo (CB), pliegue cutáneo del tríceps (PCT), circunferencia muscular del brazo (CMB), área muscular del brazo (AMB), puntuación y evaluación categóricas obtenidas utilizando la Valoración Global Subjetiva Generada por el Paciente (VGS-GP), AF y ángulo de fase estandarizado (AFS). El coeficiente Kappa se utilizó para probar el grado de concordancia entre los diagnósticos de riesgo nutricional obtenidos de diferentes métodos de evaluación nutricional. Los puntos de corte del AF a través de indicadores antropométricos y VGS-GP se determinaron utilizando la curva ROC (Receiver Operating Characteristic), y la sobrevivencia de los pacientes se analizó con el método de regresión de Cox. Resultados: los puntos de corte con mayor poder discriminatorio fueron los obtenidos de IMC (5,2) y la evaluación categórica del VGS-GP (5,4). El diagnóstico obtenido mediante estos puntos de corte mostró una asociación significativa con el riesgo de muerte de los pacientes incluidos en este trabajo. Conclusión: se recomienda utilizar el punto de corte 5.2 para el AF como criterio para la identificación de riesgo nutricional en pacientes con cáncer antes de la radioterapia.

Fundamento: A Síndrome Metabólica (SM) é uma agregação de fatores de risco que aumenta a incidência de eventos cardiovasculares e Diabete Melito (DM). O envelhecimento da população vem acompanhado de maior prevalência de SM, que varia dependendo da população estudada e do critério diagnóstico utilizado. Objetivo: Determinar a prevalência de SM em idosos por quatro critérios diagnósticos e a concordância entre esses. Métodos: Estudo transversal realizado em 243 indivíduos acima de 60 anos (180 mulheres) em Niterói (RJ). Foram avaliados através de exame clínico glicemia jejum, insulinemia jejum, perfil lipídico e medidas antropométricas - peso, estatura, circunferência abdominal e relação cintura/quadril. A prevalência de SM foi estimada utilizando critérios diagnósticos da Organização Mundial da Saúde (OMS) modificado, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATPIII), International Diabetes Federation (IDF) e Joint Interim Statement (JIS). Resultados: A prevalência foi elevada pelos quatro critérios, OMS (51,9%), NCEP-ATPIII (45,2%), IDF (64,1%) e JIS (69,1%), e a concordância entre os critérios diagnósticos pelo índice kappa foi moderada em quase todas as comparações OMS vs. IDF (k = 0,47; intervalo de confiança (IC) 95%, 0,35 - 0,58); OMS vs. NCEP-ATPIII (k = 0,51; IC 95%, 0,40 - 0,61); OMS vs. JIS (k = 0,45; IC 95%, 0,33 - 0,56); IDF vs. NCEP-ATPIII (k = 0,55, IC 95%, 0,45 - 0,65) e NCEP-ATPIII vs. JIS (k = 0,53; IC 95%, 0,43 - 0,64), exceto entre IDF vs. JIS (K= 0,89; IC 95%, 0,83 - 0,95), considerada boa. Conclusão: A prevalência de SM foi elevada pelos quatro critérios diagnósticos, principalmente pelo JIS. Houve uma boa concordância entre os critérios JIS e IDF e moderada entre os outros.

Background: Metabolic syndrome (MS) is an aggregation of risk factors that increase the incidence of cardiovascular events and diabetes mellitus (DM). Population aging is accompanied by higher prevalence of MS, which varies depending on the population studied and the diagnostic criteria used. Objective: To determine prevalence of MS in the elderly using four diagnostic criteria and agreement between them. Methods: Cross-sectional study on 243 patients older than 60 years (180 women) in Niterói, RJ. They were evaluated by clinical examination, fasting glucose, fasting insulin, lipid profile and anthropometric measurements - weight, height, waist circumference and waist/hip ratio. Prevalence of MS was estimated by World Health Organization (WHO) modified, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria. Results: Prevalence was high with the four criteria WHO (51.9%), NCEP-ATPIII (45.2%), IDF (64.1%) and JIS (69.1%), and agreement between criteria by kappa was moderate in almost all comparisons WHO vs. IDF (k = 0.47;95% confidence interval (CI), 0.35 to 0.58); WHO vs. NCEP-ATPIII (k = 0.51; 95% CI, 0.40 to 0.61); WHO vs. JIS (k = 0.45; 95% CI, 0.33 to 0.56); IDF vs. NCEP-ATPIII (k = 0.55; 95% CI, 0.45 to 0.65) and NCEP-ATPIII vs. JIS (k = 0.53; 95% CI, 0.43-0.64), except between IDF vs. JIS (K = 0.89;95% CI, 0.83 to 0.95), which was considered good. Conclusion: Prevalence of MS was high with the four diagnostic criteria, mainly by JIS. There was good agreement between JIS and IDF criteria and moderate among the others.

RESUMO É reconhecido que infecções por papilomavírus humanos de alto risco (HPV) são causa necessária, mas não suficiente para o desenvolvimento do câncer cervical. Recentemente, estudos de silenciamento gênico apontaram que a hipermetilação do gene p16INK4A é importante co-fator para a carcinogênese cervical, eliminando a função supressora de tumor da proteína p16 em lesões malignas. Entretanto poucos estudos avaliaram a relação da metilação com a progressão da doença. Nosso objetivo foi investigar o padrão de metilação do gene P16INK4A em diferentes graus de lesão cervical e sua associação com a infecção por diferentes tipos de HPV. Nosso estudo de corte transversal avaliou 141 amostras cervicais de pacientes atendidas no Hospital Moncorvo Filho, Rio de Janeiro. A detecção e tipagem do HPV foi realizada pela técnica de reação em cadeia da polimerase (PCR), e a metilação do gene P16INK4A pela PCR-metilação específica em formato nested (MSP). A frequência de HPV foi de 62,4% (88/141). O tipo mais prevalente foi o HPV16 (37%), seguido pelo HPV18 (16,3%) e HPV33/45 (15,2%). Curva ascendente foi observada quanto ao padrão de metilação do gene P16INK4A e o grau da lesão: a metilação foi identificada em somente 10,7% das amostras de epitélio normal, em 22,9% das lesões de baixo grau, em 57,1% das lesões de alto grau e em 93,1% dos carcinomas (p < 0,0001). Foram feitas análises univariada e multivariada a fim de correlacionar metilação, idade, exposição ao tabaco, infecção e genótipo de HPV. Foi encontrada correlação da metilação com a infecção pelo HPV (p < 0,0001), genótipos de alto risco (p = 0,01), lesões de alto grau (p < 0,0007) e câncer (p < 0,0001). Uma vez que infecções pelo HPV e alterações epigenéticas mostraram forte associação estatística com o carcinoma cervical, sugerimos que estes padrões de metilação possam ser avaliados como potenciais biomarcadores, combinados à detecção dos HPV oncogênicos para identificação de pacientes em risco de câncer.

SUMMARY High-risk human papillomavirus (hr-HPV) infection is necessary but not sufficient for cervical cancer development. Recently, P16INK4A gene silencing through hypermethylation has been proposed as an important cofactor in cervical carcinogenesis due to its tumor suppressor function. We aimed to investigate P16INK4A methylation status in normal and neoplastic epithelia and evaluate an association with HPV infection and genotype. This cross-sectional study was performed with 141 cervical samples from patients attending Hospital Moncorvo Filho, Rio de Janeiro. HPV detection and genotyping were performed through PCR and P16INK4A methylation by nested-methylation specific PCR (MSP). HPV frequency was 62.4% (88/141). The most common HPV were HPV16 (37%), HPV18 (16.3%) and HPV33/45(15.2%). An upward trend was observed concerning P16INK4A methylation and lesion degree: normal epithelia (10.7%), low grade lesions (22.9%), high grade (57.1%) and carcinoma (93.1%) (p < 0.0001). A multivariate analysis was performed to evaluate an association between methylation, age, tobacco exposure, HPV infection and genotyping. A correlation was found concerning methylation with HPV infection (p < 0.0001), hr-HPV (p = 0.01), HSIL (p < 0.0007) and malignant lesions (p < 0.0001). Since viral infection and epigenetic alterations are related to cervical carcinoma, we suggest that P16INK4A methylation profile maybe thoroughly investigated as a biomarker to identify patients at risk of cancer.
