Low bone mass and vitamin D in Brazilian people living with HIV under antiretroviral therapy.

We performed a cross-sectional study in 212 PLHIV under antiretroviral therapy. Bone mass was compromised in 36.5% of relatively young sample and associated with hypogonadism, older age, higher PTH levels, and metabolic syndrome. Hypovitaminosis D was present in 85%, especially those on NNRTI. PURPOSE: Previous studies have reported an increased prevalence of bone demineralization among people living with the human immunodeficiency virus (PLHIV). We aimed to assess bone mineral density (BMD), vitamin D levels, and associated risk factors in Brazilian PLHIV. METHODS: Cross-sectional study with 212 patients in a specialized assistance service. Clinical and demographic information were registered. Laboratory tests were performed, and BMD was measured at the lumbar spine, total hip/femoral neck, and forearm by dual-energy X-ray absorptiometry. Participants were classified into "with low bone mass (wLBM)" and "without low bone mass (woLBM)." Those wLBM encompasses osteoporosis, osteopenia, and below the expected range for age as recommended by the World Health Organization. RESULTS: One hundred and eighty-seven patients were included. Median age was 46.3 years (interquartile range (IQR) 40-52) and duration of HAART exposure was 11.2 years (IQR 7-15). Plasma viral load was undetectable in 79%. Hypovitaminosis D (< 30 ng/mL) was present in 85% and LBM in 36.5%. Men wLBM were more likely to have testosterone deficiency and had higher PTH levels than those woLBM. LBM in women was associated with older age, menopause, and metabolic syndrome. CONCLUSION: This study showed a high frequency of LBM in a relatively young sample, and suggests a detrimental effect of hypogonadism, older age, higher PTH levels, and metabolic syndrome. Hypovitaminosis D was frequent, especially those on non-nucleoside reverse transcriptase inhibitor, higher body mass index, and abdominal circumference.

Fat Mass Ratio in Brazilian HIV-infected Patients Under Antiretroviral Therapy and Its Relationship With Anthropometric Measurents.

INTRODUCTION: Human immunodeficiency virus-related lipodystrophy is characterized by a variety of phenotypes and metabolic changes; however, consensus has not yet been reached on its diagnostic criteria. Different cutoff values for fat mass ratio have been proposed for this specific population as an objective diagnostic criterion for lipodystrophy. This study aimed to establish sex-specific reference values for fat mass ratio and to correlate them with anthropometric measurements for the diagnosis of human immunodeficiency virus-related lipodystrophy. METHODOLOGY: A cross-sectional study was performed on 189 human immunodeficiency virus-infected patients under antiretroviral therapy. Anthropometric measurements were evaluated, and body composition was determined using dual-energy X-ray absorptiometry. Fat mass ratio was calculated as the ratio of the percentage of the trunk fat mass and the percentage of the lower limb fat mass. RESULTS: One hundred and thirty-two patients (69%) presented lipodystrophy by objective criteria. In men, the cutoff for the fat mass ratio was 1.55 (area under the receiver operating characteristic curve: 0.73 [95% confidence interval: 0.62-0.83], p = 0.000008), with a sensitivity of 62.5%, a specificity of 70.5%, a positive predictive value of 77.8%, and a negative predictive value of 53.4%. In women, the cutoff for the fat mass ratio was 0.959 (area under the receiver operating characteristic curve: 0.70 [95% confidence interval: 0.56-0.85], p = 0.03), with a sensitivity of 83.60%, a specificity of 61.5%, a positive predictive value of 90.2%, and a negative predictive value of 47.1%. Fat mass ratio was positively correlated with waist circumference (men: r = 0.246, p = 0.019; women: r = 0.302, p = 0.014) and neck circumference (men: r = 0.304, p = 0.004; women: r = 0.366, p = 0.003) in both sexes; and body mass index (r = 0.288, p = 0.006) and waist-hip ratio (r = 0.288, p = 0.006) in men. CONCLUSION: The fat mass ratio evaluated using dual-energy X-ray absorptiometry with the sex-specific cutoffs is an objective tool to define human immunodeficiency virus-related lipodystrophy.

Influence of vaccine-preventable diseases and HIV infection on demand for an infectious diseases service in Rio de Janeiro State, Brazil, over 22 years - Part II (1995-2016).

Patients' data during daily clinical care are extremely important for improving the allocation of healthcare resources and for assessing healthcare demands. The prospective gathering of these data over decades allowed us to describe the trends of infectious diseases in a tertiary hospital. The results concerning the period between 1965 and 1994 described the exponential increase in the incidence of HIV infection and its important effects on our institutional mortality. The present study describes the demand for the same hospital between 1995 and 2016. There were 4,691 admissions and the main causes of admissions were, in descending order, HIV infection (1,312, 28.0%), noninfectious diseases (447, 9.5%), meningoencephalitis (432, 9.2%), soft tissue infections (427; 9.1%), tuberculosis (272, 5.8%), pneumonias (212, 4.5%) and leptospirosis (212, 4.5%). There were 864 readmissions; most due to HIV infections (65.2%). The institutional mortality fell from 16.9% in the first two years to 5.0% in the last two years of the study. The case-fatality rates among the HIV patients decreased from more than 40% to approximately 5% over the study period. In the last two decades, the hospital experienced a decrease in demand due to vaccine-preventable diseases. The demand for children has fallen and the demand for patients over the age of 50 has increased. These results reflect the improvement in public health standards over more than half a century and the positive effects of the National Immunization Program. They also illustrate the sharp decline in the HIV case-fatality rate after the introduction of combined antiretroviral therapy.

The Use of Two-Dimensional Strain Measured by Speckle Tracking in the Identification of Incipient Ventricular Dysfunction in HIV-Infected Patients on Antiretroviral Therapy, Untreated HIV Patients and Healthy Controls / O Uso do Strain Bidimensional Obtido pelo Speckle Tracking na Identificação da Disfunção Ventricular Incipiente em Pacientes Infectados pelo HIV em Uso de Terapia Antirretroviral, Pacientes HIV não Tratados e Controles Saudáveis

Abstract Background: Most cardiovascular abnormalities in patients infected with the human immunodeficiency virus (HIV) have been associated with myocardial damage directly caused by the virus. Some cases, however, may be associated with adverse effects from antiretroviral therapy (ART). New ventricular function assessment techniques are capable of detecting early changes in the cardiac function of HIV-infected patients using or not using ART. The usefulness of these techniques has been little employed in these patients. Objectives: To investigate the potential influence of antiretroviral therapy (ART) on the occurrence of subclinical left ventricular systolic dysfunction evaluated by myocardial strain rate analysis using two-dimensional speckle tracking echocardiography (2-D Echo) in treated HIV patients compared to untreated patients and healthy individuals. Methods: Sixty-eight HIV-infected patients with no cardiovascular symptoms, normal left ventricular (LV) ejection fraction (> 0.55 on 2-D Echo) were divided into three groups: 11 patients not using antiretroviral therapy (NT), 24 using protease inhibitor (PI) and 33 using non-nucleoside reverse transcriptase inhibitor (NNRTI). We also studied 30 normal non-HIV infected individuals (Ctrl). Demographic, clinical, biochemical and anthropometric data were collected. Preliminary transthoracic echocardiography included study of myocardial strain using two-dimensional speckle tracking. We studied strain and strain rate in the seventeen left ventricular (LV) myocardial segments in the longitudinal, circumferential and radial axes. Statistical analysis of the data was done with IBM SPSS - version 20 for Windows. Upon analysis of the data, namely the normality of independent variables in the different groups and the homogeneity of the variances between the groups, Kruskal-Wallis' non-parametric test was done, followed by Dunn's multiple comparison tests to test the significance of the differences between the values measured in the study groups. A significance level of 5% was adopted for decision-making on statistical tests. Results: The mean age of HIV patients was 40 ± 8.65 years and the mean age of controls was 50 ± 11.6 years (p < 0.001). Median LV global longitudinal strain (GLS) of NT patients (-17.70%), PI patients (-18.27%) and NNRTIs (-18.47%) were significantly lower than that of the Ctrl group (-20.77%; p = 0.001). There was no significant difference in mean SLG between treated patients (PI, NNRTI) and untreated (NT) patients. No significant differences were observed in mean circumferential and radial strain, nor on circumferential and radial strain rates between the NT, PI, NNRTI and Ctrl groups. Conclusion: The data suggest that HIV patients present, on myocardial strain measured by speckle tracking, signs of early LV systolic dysfunction that seem to be unrelated to the presence of ART. The prognostic significance of this condition in these patients deserves further studies.

Resumo Fundamento: A maior parte das alterações cardiovasculares dos pacientes infectados pelo vírus da imunodeficiência humana (HIV) tem sido associada ao dano miocárdico causado diretamente pelo vírus. Alguns casos, porém, podem estar associados a efeitos adversos da terapia antirretroviral (TARV). Novas técnicas de avaliação da função ventricular são capazes de detectar modificações precoces na função cardíaca do paciente infectado pelo HIV em uso ou não de TARV. A utilidade dessas técnicas tem sido pouco empregada nesses pacientes. Objetivos: Investigar possível influência da terapia antirretroviral (TARV) na ocorrência de disfunção sistólica ventricular esquerda subclínica avaliada pela análise da taxa de deformação miocárdica (strain) por meio do speckle tracking ao ecocardiograma bidimensional (E2D) em pacientes portadores do HIV tratados, comparados com pacientes não tratados e indivíduos saudáveis. Métodos: Sessenta e oito pacientes infectados pelo HIV assintomáticos do ponto de vista cardiovascular, com fração de ejeção do ventrículo esquerdo (VE) normal (>0,55 pelo E2D) foram divididos em três grupos: 11 pacientes sem tratamento antirretroviral (ST), 24 em uso de inibidor de protease (IP) e 33 em uso de inibidor de transcriptase reversa não nucleosídeo (ITRNN). Foram estudados também 30 indivíduos normais não infectados pelo HIV (Ctrl). Foram coletados dados demográficos, clínicos, bioquímicos e antropométricos. A ecocardiografia transtorácica foi realizada incluindo no estudo inicial o estudo da deformação miocárdica pela técnica bidimensional (speckle tracking). Estudamos o strain e a sua taxa de deformação (strain rate) nos dezessete segmentos miocárdicos do ventrículo esquerdo (VE) nos eixos longitudinal, circunferencial e radial. A análise estatística dos dados foi feita com o programa IBM SPSS - versão 20 para Windows. Depois de analisados os dados, nomeadamente a normalidade das variáveis independentes nos diferentes grupos e a homogeneidade das variâncias entre os grupos, decidiu-se utilizar o teste não paramétrico de Kruskal-Wallis seguido dos testes de comparações múltiplas pelo procedimento de Dunn, para testar a significância das diferenças entre os valores medidos nos grupos em estudo. Foi considerado o nível de significância de 5% para a tomada de decisão nos testes estatísticos realizados. Resultados: A média das idades dos pacientes com HIV foi de 40 ± 8,65 anos e a idade média dos controles foi de 50 ± 11,6 anos (p < 0,001). Os valores medianos do strain longitudinal global do VE (SLG) dos pacientes ST (-17.70%), dos pacientes IP (-18.27%) e ITRNN (-18.47%) foram significativamente menores do que o grupo Ctrl (-20,77%; p = 0,001). Não houve diferença significante nos valores médios do SLGentre os pacientes tratados (IP, ITRNN) e não tratados (ST). Não foram observadas diferenças significantes nos valores médios do strain circunferencial e radial, nem nas taxas de deformação circunferencial e radial entre os grupos ST, IP, ITRNN e Ctrl. Conclusão: Os dados sugerem que pacientes com HIV apresentam, à análise da deformação miocárdica ao speckle tracking, sinais de disfunção sistólica incipiente do VE que parece não ter relação com a presença de TARV. O significado prognóstico dessa alteração nesses pacientes merece estudos futuros.

Post-surgical atypical mycobacteriosis in 125 patients in Rio de Janeiro.

INTRODUCTION: The growing incidence of post-surgical atypical mycobacteriosis (PSAM) may be related to the increased use of low- and medium-complexity video-assisted surgery. METHODS: Between April 2007 and June 2009, 125 patients were referred from the State Health Department of Rio de Janeiro for the treatment of confirmed, probable, or suspected PSAM. RESULTS: Laparoscopic cholecystectomy was the most frequent surgical procedure (48.8%) among patients. Clarithromycin, ethambutol, and terizidone were used to treat 113 patients for a mean duration of 226 days. CONCLUSIONS: Despite the need for multidrug therapy and long treatment duration, most included patients adhered to treatment and experienced cure without relapse.

Radiological aspects in computed tomography as determinants in the diagnosis of pulmonary tuberculosis in immunocompetent infants.

OBJECTIVE: To describe the chest computed tomography (CT) findings in immunocompetent children under 36 months of age with pulmonary tuberculosis. MATERIALS AND METHODS: This was a descriptive case series conducted in the city of Rio de Janeiro, Brazil, between January 2004 and July 2013, involving 20 young children who underwent CT after undergoing chest X-rays that did not provide a definitive diagnosis. RESULTS: All of the participants had lymph node enlargement and consolidations. In 15 cases (75%), the consolidations were accompanied by atelectasis. Pulmonary cavitation was seen in 10 cases (50%), and cavitation within consolidations was seen in 7 (35%). The areas of cavitation and parenchymal destruction were not seen on conventional chest X-rays. CONCLUSION: The radiological presentation of pulmonary tuberculosis in young children differs from that described in older children and adults. CT is an effective method for the early diagnosis of pulmonary tuberculosis in immunocompetent infants, allowing the rapid institution of specific treatment, which is crucial for halting disease progression, as well as for preventing local and systemic complications.

OBJETIVO: Descrever achados radiológicos na tomografia computadorizada (TC) de tórax de crianças imunocompetentes menores de 36 meses com tuberculose pulmonar. MATERIAIS E MÉTODOS: Esta série de casos foi desenvolvida na cidade do Rio de Janeiro, no período de janeiro de 2004 a julho de 2013, onde 20 pacientes foram submetidos a TC após a realização de radiografias de tórax que não definiram o diagnóstico. RESULTADOS: Todos os participantes tiveram linfonodomegalias e consolidações. Em 15 casos (75%) as consolidações tiveram atelectasia associada. Escavações pulmonares ocorreram em 10 casos (50%), havendo consolidações em 7 (35%). Áreas de escavação e destruição parenquimatosa em fase inicial não foram observadas nas radiografias simples. CONCLUSÃO: A apresentação radiológica de tuberculose pulmonar em lactentes não foi a mesma descrita em crianças maiores e adultos. A TC é um método aplicável para o diagnóstico precoce de tuberculose pulmonar em lactentes imunocompetentes, permitindo a rápida instituição de tratamento específico, que é crucial para interromper a progressão da doença e prevenir suas complicações locais e sistêmicas.

Predictive factors of dengue severity in hospitalized children and adolescents in Rio de Janeiro, Brazil.

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.

[Aspects related to the use of antiretrovirals in high complexity patients in the state of Rio de Janeiro]. / Aspectos relacionados à utilização de antirretrovirais em pacientes de alta complexidade no estado do Rio de Janeiro, Brasil.

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.

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.

Survival and tolerance to sorafenib in Child-Pugh B patients with hepatocellular carcinoma: a prospective study.

Sorafenib has been widely used to treat unresectable hepatocellular carcinoma (HCC) but most studies have been done in Child-Pugh A (CP-A) patients with well-preserved liver function. We evaluated the overall survival (OS) and tolerance to sorafenib in a large cohort of Child-Pugh B (CP-B) HCC patients as compared to CP-A HCC patients. We prospectively studied 130 patients with advanced HCC who started sorafenib between January 2011 and December 2015. Patients were classified as CP-A (n = 65) or CP-B (n = 65). The average OS for all 130 patients was 10 months. CP-A patients had a median survival rate significantly longer than CP-B patients: 12 months vs. 6 months. The OS found in our group of CP-B patients was 6.5 months, which is higher than that found in most studies done so far. When stratified, our CP-B patients had better OS than ever reported. The dose of the drug was interrupted due to adverse events (AEs) in 38 (29%) of the patients, of whom 20 (30%) were CP-A patients and 18 (28%) were CP-B patients. This real-life cohort of CP-B HCC patients treated with sorafenib had a higher survival than that described in the literature, with a satisfactory safety profile. Despite the high prevalence of severe AEs in CP-B patients, there were fewer treatment interruptions in this group, indicating that Child-Pugh B patients can tolerate treatment and may benefit from sorafenib.

Molecular diversity of human parvovirus B19 during two outbreaks of erythema infectiosum in Brazil

Abstract This study was conducted to provide information on the genetic diversity of human parvovirus B19 (B19V) circulating in the municipality of Niterói, Rio de Janeiro, Southeast Brazil during 1996-2006, a period with two distinct outbreaks of B19V infection: 1999-2000 and 2004-2005. A total of 27 sera from patients with erythema infectiosum and five sera from HIV-infected patients that tested positive for B19V DNA during the study period were analyzed. To genotype B19V strains, a semi-nested PCR for partial amplification of the capsid gene was performed and sequence analysis revealed that 31 sequences belonged to subgenotype 1a (G1a) of the main genotype 1 and one sequence was characterized as subgenotype 3b (G3b). The phylogenetic tree supported the division of the G1a into two well-defined clades with 1.3% of divergence. The low diversity of the G1a strains may be explained by the fact that all patients had acute B19V infection and 30/32 sera were collected during two distinct outbreaks. The G3b strain was from an HIV-infected patient who seroconverted to anti-B19 IgG antibodies in September/2005. This is the first report of G3b in the state of Rio de Janeiro.

Molecular diversity of human parvovirus B19 during two outbreaks of erythema infectiosum in Brazil.

This study was conducted to provide information on the genetic diversity of human parvovirus B19 (B19V) circulating in the municipality of Niterói, Rio de Janeiro, Southeast Brazil during 1996-2006, a period with two distinct outbreaks of B19V infection: 1999-2000 and 2004-2005. A total of 27 sera from patients with erythema infectiosum and five sera from HIV-infected patients that tested positive for B19V DNA during the study period were analyzed. To genotype B19V strains, a semi-nested PCR for partial amplification of the capsid gene was performed and sequence analysis revealed that 31 sequences belonged to subgenotype 1a (G1a) of the main genotype 1 and one sequence was characterized as subgenotype 3b (G3b). The phylogenetic tree supported the division of the G1a into two well-defined clades with 1.3% of divergence. The low diversity of the G1a strains may be explained by the fact that all patients had acute B19V infection and 30/32 sera were collected during two distinct outbreaks. The G3b strain was from an HIV-infected patient who seroconverted to anti-B19 IgG antibodies in September/2005. This is the first report of G3b in the state of Rio de Janeiro.

Correlation of non-alcoholic fatty liver disease and features of metabolic syndrome in morbidly obese patients in the preoperative assessment for bariatric surgery / Correlação da doença hepática gordurosa não alcoólica e síndrome metabólica em pacientes obesos mórbidos em preparo pré-operatório para cirurgia bariátrica

ABSTRACT Background: Obesity is an epidemic and chronic disease that can bring other comorbidities to the patient. Non-alcoholic fatty liver disease is present in up to 90% of these patients and can progress to hepatitis and hepatocarcinoma. The relationship of this liver disease and obesity is already well known; however, it is possible that some parameters of the comorbidities are more related than others in the pathophysiology of the disease. Aim: Was analyzed the relationship between non-alcoholic fatty liver disease (NAFLD) and the comorbidities of metabolic syndrome in morbidly obese patients. Methods: Was involved ultrasonography and laboratory assessment of obese patients before bariatric surgery. NAFLD was assessed using the same sonography parameters for all patients. Based on the results, the patients were divided into groups with and without NAFLD. Comparisons between them involved clinical and laboratory variables such as fasting blood glucose, insulin, HOMA-IR (homeostasis model assessment - insulin resistance), glycated hemoglobin, total cholesterol and fractions, triglycerides, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, C-reactive protein, albumin and ferritin. Patients who reported alcohol abuse (defined as the consumption of >14 drinks per week) or who had hepatitis were excluded. Results: Eighty-two patients (74 women and 8 men) were studied, of whom 53 (64.6%) had NAFLD and 29 (35.4%) did not. The levels of glycated hemoglobin (p=0.05) and LDL cholesterol (p=0.01) were significantly altered in patients with NAFLD. However, weight, body mass index and excess weight did not differ significantly between the groups (p=0.835, p=0.488 and p=0.727, respectively). Conclusions: Altered LDL cholesterol and glycated hemoglobin levels were related to the presence of NAFLD.

RESUMO Racional: A obesidade é doença epidêmica e crônica que pode trazer outras comorbidades ao paciente. A doença hepática gordurosa não alcoólica está presente em até 90% desses pacientes e pode evoluir para hepatite e hepatocarcinoma. A relação desta hepatopatia e a obesidade já é bem conhecida; porém, é possível que alguns parâmetros das comorbidades estejam mais relacionados do que outros na fisiopatogenia da doença. Objetivo: Correlacionar a doença hepática gordurosa não alcoólica (DHGNA) com as comorbidades da síndrome metabólica em pacientes obesos mórbidos em pré-operatório de cirurgia bariátrica. Métodos: Avaliação ultrassonográfica e laboratorial de pacientes obesos em pré-operatório para cirurgia bariátrica. Durante o preparo para a operação em todos os pacientes foi avaliada DHGNA através de ultrassonografia. De acordo com o resultado, os pacientes foram separados em dois grupos: sem DHGNA e com DHGNA. Para análise entre os grupos, avaliaram-se as seguintes variáveis clínicas e laboratoriais: insulina, HOMA-IR, hemoglobina glicada, colesterol total e frações, triglicerídeos, transaminase pirúvica, transaminase glutâmico oxalacética, gama glutamil transferase, proteína C reativa, albumina, ferritina. Os pacientes que relataram uso de bebida alcoólica ou que apresentaram hepatite foram excluídos do estudo. Resultados: Avaliou-se um total de 82 pacientes (74 mulheres e 8 homens), sendo 53 (64.6%) com DHGNA e 29 (35.4%) sem. Os níveis de hemoglobina glicada (p=0.05) e de LDL (p=0.01) mostraram-se mais relacionados no grupo de pacientes com DHGNA. Conclusão: A hemoglobina glicada e o LDL tiveram relação com a presença de DHGA.

The Correlation Between Obesity-Related Diseases and Non-alcoholic Fatty Liver Disease in Women in the Pre-operative Evaluation for Bariatric Surgery Assessed by Transient Hepatic Elastography.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a common, severe disease in obese patients. However, NAFLD is usually underestimated by ultrasonography. Liver biopsy is not routinely done in bariatric surgery or during the follow-up. This study therefore examined the correlation between metabolic syndrome and NAFLD in morbidly obese patients based on an assessment using transient hepatic elastography (THE). MATERIAL AND METHODS: This study involved 50 female patients in the pre-operative phase for bariatric surgery. Before surgery, we collected clinical, laboratory, and anthropometric variables. THE measurements were obtained using a FibroScan® device (Echosens, Paris, France), and steatosis was quantified using Controlled Attenuation Parameter software (CAP). Statistical analyses were done using linear correlation and the Kruskal-Wallis test. RESULTS: The mean of THE and CAP values were 7.56 ± 4.78 kPa and 279.94 ± 45.69 dB/m, respectively, and there was a significant linear correlation between the two measurements (r = 0.651; p < 0.001). The numbers of metabolic syndrome parameters did not influence the THE (p = 0.436) or CAP (p = 0.422) values. HbA1c and HOMA-IR showed a strong linear correlation with CAP (r = 0.643, p = 0.013 and r = 0.668, p = 0.009, respectively) and a tendency to some linear correlation with THE (r = 0.500, p = 0.05 and r = 0.500, p = 0.002, respectively). CONCLUSION: Morbidly obese women submitted to FibroScan® presented a high prevalence of severe steatosis and advanced fibrosis in our sample. Insulin resistance parameters were correlated with steatosis, but less with fibrosis.

Soroprevalência para toxoplasmose, sífilis, hepatite b, hepatite c, rubéola,citomegalovírus e vírus da imunodeficiência humana em gestantes atendidas no hospital universitário Antônio Pedro, Niterói (RJ) entre 2008 e 2012 / Seroprevalence of toxoplasmosis, syphilis, hepatitis b, hepatitisc, rubella, cytomegalovirosis and human immunodeficiency virus infection among pregnant patients followed up from 2008 to 2012 at hospital universitário Antônio Pedro, Niterói (RJ)

A triagem e o tratamento das doenças infecciosas em gestantes são de grande importância para o planejamento de ações preventivas e a elaboração de políticas de saúde materno-infantil. Objetivo: Determinar a soroprevalência de toxoplasmose, sífilis, hepatite B, hepatite C, rubéola, citomegalovírus (CMV) e infecção pelo vírus da imunodeficiência humana (HIV) em gestantes acompanhadas no Hospital Universitário Antônio Pedro, Niterói (RJ). Métodos: Foi feito um estudo transversal por meio de revisão de testes sorológicos registrados nos prontuários médicos de gestantes atendidas, de 2008 a 2012, no Ambulatório de Pré-Natal. Resultados: As prevalências encontradas foram: 61,4 (IgG) e 2,4% (IgM) para toxoplasmose; 95,1 (IgG) e 0,5% (IgM) para rubéola; 95,1 (IgG) e 1,2% (IgM) para CMV; 0,9% para hepatite B (HBsAg); 1,6% para hepatite C; 1,5% para sífilis; e 5,8% para infecção pelo HIV. Não houve, entre gestantes infectadas e não infectadas pelo HIV, diferenças estatisticamente significativas nas frequências das infecções estudadas. As taxas de transmissão vertical foram de 4,2% (2/48) para o HIV; 33,3% (5/15) para toxoplasmose; e 22,2% (2/9) para sífilis. Foram detectadas alterações compatíveis com rubéola congênita em 1/5 crianças cuja mãe apresentava IgM e IgG positivas para tal infecção durante a gestação. A coinfecção HIV/toxoplasmose ocorreu em uma criança. Conclusão: O número de gestantes susceptíveis à toxoplasmose (38,8%) e ao vírus da hepatite B (VHB) (66,3%) revela a necessidade de medidas diagnósticas e preventivas da toxoplasmose durante a gestação e vacinação para o VHB, visando diminuir o risco dessas infecções durante a gravidez, melhorando, assim, a saúde materno-infantil.

Screening and treatment of infectious diseases in pregnant women have great importance in planning preventive actions and development of maternal and child health policies. Objective: To evaluate the seroprevalence of toxoplasmosis, syphilis, hepatitis B, hepatitis C, rubella, cytomegalovirosis and human immunodeficiency virus (HIV) infection among pregnant women followed up at a University Hospital of Niterói, RJ. Methods: A cross-sectional study was done by reviewing serological tests recorded in the medical records of pregnant women attending the antenatal service of the Hospital Antônio Pedro, Universidade Federal Fluminense, from 2008 to 2012. Results: The seroprevalences found were 61.4 (IgG) and 2.4% (IgM) for toxoplasmosis; 95.1 (IgG) and 0.5% (IgM) for rubella; 95.1 (IgG) and 1.2% (IgM) for cytomegaloviruosis; 0.9% for hepatitis B surface antigen; 1.6% for hepatitis C virus; 1.5% for syphilis and 5.8% for HIV infection. There were no statistically significant differences between seroprevalences of patients with or without HIV infection. The rates of congenital transmission were 4.2% (2/48) for HIV, 33.3% (5/15) for toxoplasmosis, and 22.2% (2/9) for syphilis. There were congenital abnormalities in 1/5 newborn whose mother was seropositive for rubella IgG and/or IgM in the prenatal routine. Coinfection HIV/toxoplasmosis was found in one newborn. Conclusion: The large proportion of pregnant women susceptible to toxoplasmosis (38.8%) and hepatitis B (66.3%) shows the necessity of diagnostic and preventive measures for toxoplasmosis and HBV vaccination to reduce the risk of vertical transmission of these infections, thus improving the health of mother and newborn.
