Prevalêncıa e fatores predıtıvos assocıados à posıtıvıdade dos marcadores serológıcos do SARS-COV-2 em pacıentes com doença ınflamatórıa ıntestınal em um centro de referêncıa em DII / Prevalence and predictive factors associated with positivity of sars-cov-2 serological markers in patients with inflammatory bowel disease at an ibd referral center

ABSTRACT Background: Data related to SARS-CoV-2 exposure rates in patients with inflammatory bowel diseases (IBD) are scarce. Objective - Our aim was to determine the prevalence of serological markers of SARS-Cov-2 and the predictive factors for positivity in patients with IBD. Methods: This is a cross-sectional, observational study carried out from May to September 2020. SARS-CoV-2 serological markers were determined using chemiluminescence immunoassay in 233 IBD patients without evidence of COVID-19 symptoms. Patient age was 36.6±11.1 years, 118 patients were male (50.6%), and 63.1% had Crohn's disease. Patient clinical data were extracted from individual electronic medical records and complemented by a structured interview. Results: Twenty-six out of the 233 patients with IBD had positive serum markers for SARS-CoV-2 (11.2%). Female sex (P<0.003), extra-intestinal manifestations (P=0.004), use of corticosteroids (P=0.049), and previous contact with individuals with flu-like symptoms (P<0.001) or confirmed diagnosis of COVID-19 (P<0.001), were associated with a significant increased rate of positive SARS-Cov-2 serological markers. No significant difference was observed regarding to adherence to protection measures and positivity of SARS-Cov-2 serological markers (P>0.05). Conclusion: SARS-CoV-2 previous infection in IBD patients was not that uncommon, and its prevalence was 11.2% in our series. Positivity to SARS-CoV-2 serological markers was associated with female sex, extra-intestinal manifestations, use of corticosteroids, and contact with individuals with suspected or confirmed COVID-19. Studies with longer follow-up periods are needed to confirm these findings.

RESUMO Contexto: Dados relacionados às taxas de exposição ao SARS-CoV-2 em pacientes com doenças inflamatórias intestinais (DII) são escassos. Objetivo Nosso objetivo foi determinar a prevalência de marcadores sorológicos do SARS-Cov-2 e os fatores preditivos de positividade em pacientes com DII. Métodos: Este foi um estudo transversal observacional realizado no período de maio a setembro de 2020. Os marcadores sorológicos SARS-CoV-2 foram determinados por imunoensaio de quimioluminescência em 233 pacientes com DII sem evidência de sintomas de COVID-19. A idade dos pacientes foi 36,6±11,1 anos, 118 pacientes eram do sexo masculino (50,6%) e 63,1% tinham doença de Crohn. Os dados clínicos dos pacientes foram extraídos de prontuários médicos eletrônicos individuais e complementados por meio de uma entrevista estruturada. Resultados: Vinte e seis dos 233 pacientes com DII apresentaram marcadores sorológicos positivos para SARS-CoV-2 (11,2%). Sexo feminino (P<0,003), manifestações extra-intestinais (P=0,004), uso de corticosteroides (P=0,049) e contato prévio com indivíduos com sintomas gripais (P<0,001) ou diagnóstico confirmado de COVID -19 (P<0,001), foram associados a um aumento significativo da taxa de positividade para marcadores sorológicos do SARS-Cov-2. Não foi observada diferença significativa em relação à adesão às medidas de proteção e positividade dos marcadores sorológicos para o SARS-Cov-2 (P>0,05). Conclusão: A infecção prévia pelo SARS-CoV-2 não é tão incomum em pacientes com DII e sua prevalência em nossa série foi de 11,2%. A positividade aos marcadores sorológicos SARS-CoV-2 foi associada ao sexo feminino, manifestações extra-intestinais, uso de corticosteroides e contato com indivíduos com suspeita ou diagnóstico confirmado de COVID-19. Estudos com períodos de acompanhamento mais longos são necessários para confirmar esses achados.

Does ascitic fluid filtration improve the microbiological diagnosis of spontaneous bacterial peritonitis? An experimental laboratory study / A filtração do líquido ascítico melhora o diagnóstico microbiológico da peritonite bacteriana espontânea? Um estudo experimental laboratorial

Background: Spontaneous Bacterial Peritonitis (SBP) is a serious and frequent complication among cirrhotic patients with ascites and can be diagnosed by cytological analysis of the ascitic fluid. The microbiological culture of ascitic fluid, however, is positive in less than 40% of SBP cases, which often results in inappropriate antimicrobial therapy. Empirical therapy may be suboptimal, increasing patient's risk of aggravation, or overestimated, unnecessarily boosting bacterial resistance. Objective: This experimental laboratory study aimed to standardize and verify the technical feasibility of ascitic fluid vacuum filtration, as a way to optimize the etiological diagnosis of SBP, compared to the automated method. Method: The method evaluated and standardized in this study was ascitic fluid vacuum filtration. Its principle is the concentration of bacteria on a filter membrane. Results: This study included 36 cirrhotic patients treated at a public university hospital between 11.13.2017 and 06.30.2019. Among them, 47.2% (17/36) presented cytology test results compatible with SBP. For these patients, culture sensitivity using the automated method was 35.3% (6/17), against 11.8% (2/17) with the vacuum filtration method. Conclusion: In conclusion, vacuum filtration does not improve the microbiological diagnosis of SBP in this population compared to the automated method (AU)

Contexto: A Peritonite Bacteriana Espontânea (PBE) é uma complicação grave e frequente entre pacientes cirróticos com ascite, diagnosticada por meio da análise citológica do líquido ascítico. A cultura microbiológica do líquido ascítico, por sua vez, é positiva em menos de 40% dos casos de PBE, o que resulta frequentemente na instituição de terapia antimicrobiana inapropriada. A terapia empírica pode ser subótima, aumentando o risco de agravamento do paciente, ou superestimada, impulsionando desnecessariamente a resistência bacteriana. Objetivo: Estudo experimental laboratorial, propôs padronizar e verificar a viabilidade técnica da filtração a vácuo do líquido ascítico, como forma de otimizar o diagnóstico etiológico na PBE, comparativamente ao sistema automatizado de culturas de sangue. Método: O método avaliado e padronizado neste estudo foi a da filtragem a vácuo do líquido ascítico. Esse tem como princípio a concentração da bactéria em uma membrana filtrante. Resultados: Nesse estudo, foram incluídos 36 pacientes cirróticos atendidos em um hospital público universitário, entre 13.11.2017 e 30.06.2019. Entre eles, 47,2% (17/36) apresentaram citologia compatível com PBE. Nesses, a sensibilidade da cultura pelo método semi-automatizado foi de 35,3% (6/17) e da cultura pelo método da filtragem a vácuo foi de 11,8% (2/17). Conclusão: Em conclusão, a filtragem a vácuo não melhora o diagnóstico microbiológico da PBE em relação ao método automatizado (AU)

Cryptococcosis by Cryptococcus neoformans/Cryptococcus gattii Species Complexes in non-HIV-Infected Patients in Southeastern Brazil

Abstract INTRODUCTION: The clinical manifestations of cryptococcosis are usually associated with the infecting agents Cryptococcus neoformans (CN) and C. gattii (CG) species complexes and the host. In this study, non-HIV-infected patients, at a university hospital in southeastern Brazil, had epidemiological and clinical data associated with cryptococcal disease and isolated Cryptococcus species: CN - 24 patients and CG - 12 patients. METHODS: The comparison was comprised of demographic data, predisposing factors, clinical and laboratory manifestations, and outcomes of cryptococcosis patients treated between 2000 and 2016. Immunocompetent and immunosuppressed patients were also compared, irrespective of the infecting species. Cryptococcus spp. were genotyped by PCR-RFLP analysis of the URA5 gene. RESULTS: Infections by the CN species complex (100% VNI genotype) were associated with drug immunosuppression and fungemia, and patients infected with the CG species complex (83% VG II and 17% VGI genotypes) had more evident environmental exposure and higher humoral response. CN and CG affected patients with or without comorbidities. CONCLUSIONS: Diabetes mellitus, other chronic non-infectious diseases, and alcoholism were likely predisposing factors for infection by both CN and CG species. Immunocompetent patients, independent of the infecting Cryptococcus species complexes, showed a higher occurrence of meningitis and a trend toward less fungal dissemination and longer survival than immunosuppressed hosts.

Influence of antiretroviral therapy on bone metabolism of patients with chronic hepatitis B: a review

Abstract Hepatitis B is a major public health problem worldwide and associated with significant mortality. To prevent or delay the deleterious effects of chronic infection by the hepatitis B virus, patients should be carefully followed, and antiviral therapy indicated according to specific recommendations. Currently, available drugs inhibit viral replication and slow or stop the progression of inflammation and fibrosis of the liver. However, the drugs for oral use in the treatment of hepatitis B, jointly referred to as nucleoside/nucleotide analogs, are indicated for prolonged use and have potential side effects. The reduction in bone mineral density was associated with the use of tenofovir, already evaluated in patients infected with HIV because the drug is also part of the therapeutic arsenal for this viral infection. There are few studies on the effects of tenofovir in patients with mono hepatitis B. Therefore, this literature review proposes to examine how hepatitis B acts in the body and the mechanisms by which antiretroviral drugs (especially tenofovir) can affect bone metabolism.

First-wave protease inhibitors for hepatitis C genotype 1 treatment: a real-life experience in Brazilian patients

Abstract INTRODUCTION: Licensed for chronic hepatitis C treatment in 2011, the protease inhibitors (PIs) telaprevir (TVR) and boceprevir (BOC), which have high sustained viral responses (SVR), ushered a new era characterized by the development of direct-action drugs against the hepatitis C virus (HCV). The aim of this study was to analyze the effectiveness and safety of BOC and TVR administered with pegylated interferon and ribavirin and to share the experience of a Brazilian reference center. METHODS: A retrospective descriptive study was conducted in patients with HCV genotype 1 infection who started treatment between July 2013 and December 2015. Data were collected using a computerized system. RESULTS: A total of 115 subjects were included, of which 58 (50.4 %) had liver cirrhosis and 103 (89.6 %) used TVR. The overall SVR rate was 61.7 % (62.1 % for TVR and 58.3 % for BOC). The presence of cirrhosis was associated with a lower SVR rate, whereas patients who relapsed after prior therapy had a greater chance of showing SVR than did non-responders. The incidence of adverse drug reactions (ADRs) was high. Almost all patients (~100 %) presented with hematologic events. Furthermore, treatment had to be discontinued in 15 subjects (13 %) due to severe ADRs. CONCLUSIONS: In conclusion, the SVR rates in our study were lower than those reported in pre-marketing studies but were comparable to real-life data. ADRs, particularly hematological ADRs, were more common compared to those in previous studies and resulted in a high rate of treatment discontinuity.

Técnicas de manejo comportamental não farmacológicas na odontopediatria / Behavioral management techniques non-pharmacological in pediatric dentistry

É habitual, na vivência odontológica, deparar-se com variados tipos de comportamentos indesejados, gerados principalmente pelo medo, ansiedade, birra ou dor, interferindo no atendimento odontológico. Nesses casos, o odontopediatra poderá utilizar técnicas de manejo comportamental não farmacológicas, auxiliando, assim, no tratamento do paciente infantil. Entretanto, para que tais técnicas sejam mais efetivas, é necessário conhecer suas possíveis restrições quanto à faixa etária e perfil de cada criança, de modo a promover e estabelecer segurança e qualidade ao atendimento. Este trabalho tem como objetivo revisar e discutir por meio de literaturas as técnicas de controle comportamental em odontopediatria

It is customary in the dental experience to face different kinds of unwanted behaviors, and these are generated mostly by fear, anxiety, tantrums or pain, thus interfering with dental care. In these cases, the dentist can use behavioral management techniques non-pharmacological, thereby assisting in the treatment of child patient. However in order to such techniques be more effective, it is necessary to know their potential restrictions on the age and profile of each child in order to promote and establish safety and quality service. This work aims to review and discuss through the literatures the behavioral control techniques in pediatric dentistry

Secular trends in Klebsiella pneumoniae isolated in a tertiary-care hospital: increasing prevalence and accelerated decline in antimicrobial susceptibility

Abstract: INTRODUCTION Klebsiella pneumoniae has become an increasingly important etiologic agent of nosocomial infections in recent years. This is mainly due to the expression of virulence factors and development of resistance to several antimicrobial drugs. METHODS This retrospective study examines data obtained from the microbiology laboratory of a Brazilian tertiary-care hospital. To assess temporal trends in prevalence and antimicrobial susceptibility, K. pneumoniae isolates were analyzed from 2000 to 2013. The relative frequencies of K. pneumoniae isolation were calculated among all Gram-negative bacilli isolated in each period analyzed. Susceptibility tests were performed using automated systems. RESULTS: From 2000-2006, K. pneumonia isolates comprised 10.7% of isolated Gram-negative bacilli (455/4260). From 2007-2013, this percentage was 18.1% (965/5331). Strictly considering isolates from bloodstream infections, the relative annual prevalence of K. pneumoniae increased from 14-17% to 27-32% during the same periods. A progressive decrease in K. pneumoniae susceptibility to all antimicrobial agents assessed was detected. Partial resistance was also observed to antimicrobial drugs that have been used more recently, such as colistin and tigecycline. CONCLUSIONS Our study indicates that K. pneumoniae has become a major pathogen among hospitalized patients and confirms its recent trend of increasing antimicrobial resistance.

Introdução: As queimaduras são lesões de grande morbidade e mortalidade que geram considerável ônus para o estado. Este estudo tem como objetivo traçar o perfil epidemiológico dos pacientes internados na Unidade de Tratamento de Queimados (UTQ) do Hospital Geral de Vila Penteado (HGVP/SP). Método: Foram analisados os dados de internações de pacientes na UTQ do HGVP, no período de Janeiro/2012 a Julho/2013, sendo avaliadas as seguintes variáveis: gênero, idade, causa e extensão da queimadura, intervalo entre queimadura/internação, tempo de internação e evolução do paciente. Resultados: Observou-se predominância das internações em homens (65,8%). Em relação à idade, houve maior concentração de queimados na população adulta (80%). O fogo foi a principal causa de lesões (58,5%), seguido pela escaldadura (19,5%); 62% das queimaduras ocorreram no domicílio e 11,5%, no trabalho. Constatou-se que a maioria das vítimas (56,1%) apresentaram queimaduras de médio e grande porte e que 46,3% dos pacientes foram admitidos nas primeiras 24 horas pós-queimaduras. Quanto ao tempo de internação, foram verificados períodos inferiores a 15 dias como sendo os de maior incidência (55,4%). Obteve-se uma taxa de altas hospitalares igual a 83%, contra uma taxa de óbitos de 17%. Conclusão: Este estudo demonstrou o perfil de queimaduras e internações na UTQ do HGVP compatível com a grande maioria dos dados de outros centros especializados, ressaltando a importância dos estudos epidemiológicos que visam à prevenção desse problema.

Introduction: Burns are injuries with major morbidity and mortality and are a considerable burden on the government. The aim of this study was to investigate the epidemiological profile of patients admitted to the burn care unit (BCU) of the Vila Penteado General Hospital (HGVP/SP). Method: The data analyzed were derived from patient admissions to the BCU of the HGVP, from January 2012 to July 2013, using the following variables: sex, age, cause and extent of the burn, time between burn/admission, estratificalength of stay, and patient's progress. Results: The majority of admissions were observed in men (65.8%). There was a greater percentage of burn patients in the adult population (80%). Fire was the main cause of injury (58.5%), followed by scalding (19.5%); 62% of burns occurred at home and 11.5% at work. Most victims (56.1%) had medium and large burns, and 46.3% of the patients were admitted in the first 24 hours after a burn. A length of stay of less than 15 days was most common (55.4%). The hospital discharge rate was 83% with a death rate of 17%. Conclusion: This study demonstrated that the epidemiological profile for burns and admissions to the BCU of the HGVP was consistent with the great majority of data from other specialty centers, and emphasizes the importance of epidemiological studies on prevention.

Histoplasmosis in immunocompetent individuals living in an endemic area in the Brazilian Southeast

Introduction The distribution of infection by Histoplasma capsulatum in Brazil is heterogeneous, and the number of cases affecting immunocompetent individuals is relatively small. This study reports the epidemiological and clinical data regarding histoplasmosis in non-immunosuppressed individuals. Methods The study included only the immunocompetent patients with histoplasmosis who were diagnosed between 1970 and 2012 at a university hospital located in Ribeirão Preto, State of São Paulo, Brazil. Clinical and epidemiological data were collected retrospectively from the patient records. Results Of the 123 patients analyzed, 95 had an active disease that manifested in the different clinical forms of histoplasmosis. Men were the predominant gender, and most patients resided in the Northeast of the State of São Paulo and in the nearby municipalities of the State of Minas Gerais. The risk factors for acquiring histoplasmosis and prolonged contact in a rural environment were recorded in 43.9% and 82.9% of cases, respectively. Smoking, alcoholism, and comorbidity rates were high among the patients with the chronic pulmonary and subacute/chronic disseminated forms of histoplasmosis. Many patients achieved clinical cure spontaneously, but 58.9% required antifungals; the disease lethality rate was 5.3%. Conclusions Immunocompetent individuals manifested the diverse clinical forms of histoplasmosis over a period of 4 decades, revealing an additional endemic area of this fungal disease in the Brazilian Southeast. .

Clinical and laboratory findings related to a favorable evolution of hantavirus pulmonary syndrome

Pouco se conhece sobre os fatores determinantes de bom prognóstico na síndrome cardiopulmonar por hantavírus. Foram revisados os prontuários médicos de 27 pacientes com diagnóstico confirmado de síndrome cardiopulmonar por hantavirus com o objetivo de avaliar dados clínicos e laboratoriais eventualmente associados com bom prognóstico dos pacientes. Os seguintes fatores foram associados com evolução clínica favorável quando analisados na admissão hospitalar: pressão arterial sistólica maior ou igual a 100mmHg (p=0,07); freqüência cardíaca abaixo de 100/minuto (p=0,01); níveis de creatinina sérica abaixo de 1,6mg/dl (p=0,03); pH do sangue arterial igual ou maior que 7,35 (p=0,03); bicarbonato sanguíneo igual ou maior que 15mEq/dl (p=0,03); saturação de oxigênio arterial maior que 84% (p=0,02); menor volume infundido (p=0.008) e ausência de indicação de aminas vasoativas (p< 0,001). Dessa forma, ausência de sinais clínicos e laboratoriais de choque circulatório na admissão hospitalar foi associada com bom prognóstico nos pacientes com síndrome cardiopulmonar por hantavirus.
