ABSTRACT

Abstract Objective: To identify oral characteristics found in children with liver disease in programming for liver transplantation. Data source: The methodology was written according to PRISMA-ScR. We adopted the methodological framework and recommendations for this type of review by Arksey and O'Malley and the Joanna Briggs Institute. The protocol was registered in the Open Science Framework (https://doi.org/10.17605/OSF.IO/QCU4W). A systematic search (Medline/PubMed, Scopus, Web of Science, and ProQuest) was conducted to identify studies that met the inclusion criteria: systematic reviews; prospective clinical trials (parallel or crossover group designs); observational studies (cohort, case-control, and cross-sectional studies); clinical case series; and case reports evaluating children with liver disease in preparation for transplantation. The last search was conducted in July 2021, and no restrictions were imposed as to language or year of publication. Studies presenting mixed data with post-transplant evaluation, and studies evaluating not only liver transplantation but also other solid organs were excluded. Screening, inclusion, and data extraction were performed by two reviewers independently. A narrative synthesis was conducted to describe the findings of the study. Data synthesis: The bibliographic search identified 830 references. A total of 21 articles were read in their entirety after the inclusion criteria assessment. Finally, after evaluating the exclusion criteria, only 3 studies were considered for the qualitative analysis. Conclusions: Children with liver disease in preparation for transplantation may present enamel defects, tooth pigmentation, caries, gingivitis, and opportunistic infections such as candidiasis.


RESUMO Objetivo: Identificar características bucais em crianças hepatopatas em programação para o transplante hepático. Fontes de dados: A metodologia foi descrita de acordo com o PRISMA-ScR. Adotamos a estrutura metodológica e recomendações para este tipo de revisão por Arksey e O'Malley e o Instituto Joanna Briggs. O protocolo foi registrado no Open Science Framework (https://doi.org/10.17605/OSF.IO/QCU4W). Uma pesquisa sistemática (Medline/PubMed, Scopus, Web of Science e ProQuest) foi conduzida para identificar estudos que preenchessem os critérios de inclusão: revisões sistemáticas; ensaios clínicos prospectivos (desenhos de grupos paralelos ou cruzados); estudos observacionais (coorte, caso-controle e estudos transversais); séries de casos clínicos; e relatos de casos que avaliam crianças com doenças hepáticas em preparação para o transplante. A última busca foi conduzida em julho de 2021, e não foram impostas restrições quanto ao idioma ou ano de publicação. Foram excluídos estudos que apresentavam dados mistos com avaliação pós-transplante e estudos que avaliavam não só o transplante de fígado, mas também de outros órgãos sólidos. O rastreio, inclusão e extração de dados foram realizados por dois revisores independentemente. Foi conduzida uma síntese narrativa para identificar os resultados do estudo. Síntese dos dados: A pesquisa bibliográfica identificou 830 referências. Foram lidos 21 artigos na íntegra após avaliação dos critérios de inclusão. Finalmente, após a avaliação dos critérios de exclusão, apenas três estudos foram considerados para análise. Conclusões Crianças com doença hepática em preparação para o transplante podem apresentar defeitos de esmalte, pigmentação dentária, cárie, gengivite além de infecções oportunistas como a candidíase.

ABSTRACT

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.

ABSTRACT

Abstract To assess the impact of oral conditions on the oral health-related quality of life (OHRQoL) of pediatric liver transplant candidates. This cross-sectional study included 60 children aged 13 to 48 months who were liver transplant candidates that attended the AC Camargo Cancer Center, São Paulo, Brazil. On the day of oral examinations, the children's mothers were invited to answer two questionnaires; one related to children's OHRQoL using the B-ECOHIS and another related to socioeconomic/demographic characteristics. Thereafter, a single, adequately trained dentist carried out children's oral examinations for gingival inflammation (Silness-Löe index), dental plaque (Green-Vermillion Simplified index), dental caries (dmft index), developmental defects of enamel (DDE index), tooth discoloration, oral mucosal/lip alterations. The data collected also included socioeconomic/demographic characteristics and liver disease. The adjusted Poisson regression model was used to associate children's socioeconomic/demographic characteristics and clinical conditions to the outcome. The adjusted regression model showed that children with untreated caries lesions (RR = 3.35, p < 0.0001) and tooth discoloration (RR = 1.74, p = 0.04) had poorer total B-ECOHIS scores. Dental discoloration and untreated caries lesions had a negative impact on the OHRQoL in pediatric liver transplant candidates.

ABSTRACT

Abstract Objective: To describe the demographic, clinical, laboratory and molecular characteristics of patients with lysosomal acid lipase deficiency. Methods: A retrospective review of the medical records of children with the disease. Results: Seven children with lysosomal acid lipase deficiency (5 male; 2 female); 6 were mixed race, and 1 was black. The mean ages at the first onset of symptoms and at diagnosis were 5.0 years (4 months to 9 years) and 6.9 years (3-10 years), respectively. Symptom manifestations at onset were: 3 patients had abdominal pain, one had bone/joint pain due to rickets, and 1 had chronic diarrhea and respiratory insufficiency due to interstitial pneumonitis. One was asymptomatic, and clinical suspicion arose due to hepatomegaly. Six patients had hepatomegaly, and none had splenomegaly. Two patients were siblings. Enzymatic assay and molecular analysis confirmed the diagnoses. Genetic analysis revealed a rare pathogenic variant (p.L89P) in three patients, described only once in medical literature and never described in Brazil. None of those patients were related to each other. Lysosomal acid lipase deficiency was previously described as an autosomal recessive disease, but three patients were heterozygous and undoubtedly had the disease (low enzyme activity, suggestive lab findings and clinical symptoms). Conclusion: This case series supports that lysosomal acid lipase deficiency can present with highly heterogeneous signs and symptoms among patients, but it should be considered in children presenting with gastrointestinal symptoms associated with dyslipidemia. We describe a rare variant in three non-related patients that may suggest a Brazilian genotype for lysosomal acid lipase deficiency.


Resumo: Objetivo: Descrever as características demográficas, clínicas, laboratoriais e moleculares de pacientes com deficiência de lipase ácida lisossomal. Métodos: Análise retrospectiva dos prontuários médicos de crianças com a deficiência de lipase ácida lisossomal. Resultados: Sete crianças com deficiência de lipase ácida lisossomal (5 M:2F); seis eram pardas e uma negra. As faixas etárias no início dos sintomas e no diagnóstico foram 5 anos (4 meses a 9 anos) e 6,9 anos (3 a 10 anos), respectivamente. As manifestações dos sintomas no início foram as que seguem: três pacientes apresentaram dor abdominal, um apresentou dor nos ossos/articulações devido a raquitismo e um apresentou diarreia crônica e insuficiência respiratória devido à pneumonite intersticial. Os outros não apresentaram sintomas e a suspeita clínica surgiu devido à hepatomegalia. Seis pacientes apresentaram hepatomegalia e um apresentou esplenomegalia. Dois pacientes eram irmãos. O ensaio enzimético e a análise molecular confirmaram os diagnósticos. A análise genética revelou uma variante patogênica rara (p.L89P) em três pacientes, descrita uma única vez na literatura médica e nunca descrita no Brasil. Nenhum desses pacientes tinha parentesco com os outros. A deficiência de lipase ácida lisossomal foi anteriormente descrita como uma doença recessiva autossômica, porém três pacientes eram heterozigotos e, sem dúvida, apresentaram a doença (atividade enzimática baixa, achados laboratoriais sugestivos e sintomas clínicos). Conclusão: Esta casuística afirma que a deficiência de lipase ácida lisossomal pode se manifestar com sinais e sintomas altamente heterogêneos entre os pacientes, porém deve ser considerada em crianças que apresentam sintomas gastrointestinais associados à dislipidemia. Descrevemos uma variante rara em três pacientes não relacionados que pode sugerir um genótipo brasileiro para deficiência de lipase ácida lisossomal.

ABSTRACT

Abstract Objective: This large study with a long-term follow-up aimed to evaluate the clinical presentation, laboratory findings, histological profile, treatments, and outcomes of children and adolescents with autoimmune hepatitis. Methods: The medical records of 828 children and adolescents with autoimmune hepatitis were reviewed. A questionnaire was used to collect anonymous data on clinical presentation, biochemical and histological findings, and treatments. Results: Of all patients, 89.6% had autoimmune hepatitis-1 and 10.4% had autoimmune hepatitis-2. The female sex was predominant in both groups. The median age at symptom onset was 111.5 (6; 210) and 53.5 (8; 165) months in the patients with autoimmune hepatitis 1 and autoimmune hepatitis-2, respectively. Acute clinical onset was observed in 56.1% and 58.8% and insidious symptoms in 43.9% and 41.2% of the patients with autoimmune hepatitis-1 and autoimmune hepatitis-2, respectively. The risk of hepatic failure was 1.6-fold higher for autoimmune hepatitis-2. Fulminant hepatic failure occurred in 3.6% and 10.6% of the patients with autoimmune hepatitis-1 and autoimmune hepatitis-2, respectively; the risk was 3.1-fold higher for autoimmune hepatitis-2. The gamma globulin and immunoglobulin G levels were significantly higher in autoimmune hepatitis-1, while the immunoglobulin A and C3 levels were lower in autoimmune hepatitis-2. Cirrhosis was observed in 22.4% of the patients; biochemical remission was achieved in 76.2%. The actuarial survival rate was 93.0%. A total of 4.6% underwent liver transplantation, and 6.9% died (autoimmune hepatitis-1: 7.5%; autoimmune hepatitis-2: 2.4%). Conclusions: In this large clinical series of Brazilian children and adolescents, autoimmune hepatitis-1 was more frequent, and patients with autoimmune hepatitis-2 exhibited higher disease remission rates with earlier response to treatment. Patients with autoimmune hepatitis-1 had a higher risk of death.


Resumo Objetivo: Este estudo com acompanhamento de longo prazo visou a avaliar o quadro clínico, os achados laboratoriais, o perfil histológico, os tratamentos e os resultados de crianças e adolescentes com hepatite autoimune. Métodos: Foram analisados os prontuários médicos de 828 crianças e adolescentes com HAI. Foi usado um questionário para coletar os dados anônimos sobre o quadro clínico, os achados bioquímicos e histológicos e os tratamentos. Resultados: De todos os pacientes, 89,6% tinham hepatite autoimune-1 e 10,4% hepatite autoimune-2. O sexo feminino foi predominante nos dois grupos. A idade média no início dos sintomas foi 111,5 (6; 210) e 53,5 (8; 165) meses nos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente. Foi observado início clínico agudo em 56,1% e 58,8% e sintomas insidiosos em 43,9% e 41,2% dos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente. A probabilidade de insuficiência hepática foi 1,6 vezes maior para hepatite autoimune-2; 3,6% e 10,6% dos pacientes com hepatite autoimune-1 e hepatite autoimune-2, respectivamente, apresentaram insuficiência hepática fulminante; o risco foi 3,1 vezes maior para hepatite autoimune-2. Os níveis de gamaglobulina e imunoglobulina G foram significativamente maiores nos pacientes com hepatite autoimune-1, ao passo que os níveis de imunoglobulina A e C3 foram menores em pacientes com hepatite autoimune-2; 22,4% dos pacientes apresentaram cirrose e a remissão bioquímica foi atingida em 76,2%. A taxa de sobrevida atuarial foi de 93,0%. Um total de 4,6% pacientes foram submetidos a transplante de fígado e 6,9% morreram (hepatite autoimune-1: 7,5%; hepatite autoimune-2: 2,4%). Conclusões: Nesta grande série clínica de crianças e adolescentes brasileiros, a hepatite autoimune-1 foi mais frequente e os pacientes com hepatite autoimune-2 mostraram maiores taxas de remissão da doença com respostas mais rápidas aos tratamentos. Os pacientes com hepatite autoimune-1 apresentaram maior risco de óbito.

ABSTRACT

Abstract Objective: The objective of this study was to evaluate the health-related quality of life in children and adolescents with autoimmune hepatitis. Methods: A cross-sectional assessment with the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0) was completed for 80 patients with autoimmune hepatitis and 45 healthy controls. Demographic data, prednisone dose, disease remission state, disease severity, and abdominal pain were also evaluated. Results: Based on the child self-reports, physical, emotional, school, and total scores were significantly lower in autoimmune hepatitis patients when compared with controls (p < 0.05). Based on the parental reports, only the physical and total scores were significantly lower in autoimmune hepatitis patients versus controls (p < 0.05). Further analysis in autoimmune hepatitis patients with abdominal pain in the last month revealed significantly lower physical, social, and total median scores (p < 0.05). No differences were observed based on disease remission state or disease severity (p > 0.05). Autoimmune hepatitis patients who received a prednisone dose below 0.16 mg/kg/day at the time of the interview showed significantly higher physical scores than those who received a dose similar to or above 0.16 mg/kg/day (87.5 [50-100] vs. 75 [15.63-100], p = 0.006). Conclusions: Reduced scores in the physical, emotional, and school domains were observed in pediatric autoimmune hepatitis patients compared to control patients. Abdominal pain and corticosteroid dose negatively influenced the health-related quality of life in children and adolescents with autoimmune hepatitis.


Resumo Objetivo: Avaliar a qualidade de vida relacionada à saúde em crianças e adolescentes com hepatite autoimune (HAI). Métodos: Foi concluída uma avaliação transversal com o Inventário Pediátrico de Qualidade de Vida 4.0 (PedsQL 4.0) para 80 pacientes com hepatite autoimune e 45 controles saudáveis. Os dados demográficos, a dose de prednisona, o estado de remissão da doença, a gravidade da doença e dor abdominal também foram avaliados. Resultados: Com base nos autorrelatos das crianças, os escores físico, emocional, escolar e total foram significativamente menores em pacientes com hepatite autoimune em comparação com os controles (p < 0,05). Com base nos relatos dos pais, apenas os escores físico e total foram significativamente menores em pacientes com hepatite autoimune em comparação com os controles (p < 0,05). Uma análise adicional em pacientes com hepatite autoimune com dor abdominal no mês passado revelou escores médios físico, social e total significativamente menores (p < 0,05). Nenhuma diferença foi observada com base no estado de remissão da doença ou na gravidade da doença (p > 0,05). Os pacientes com hepatite autoimune que receberam uma dose de prednisona abaixo de 0,16 mg/kg/dia no momento da entrevista mostraram escores físicos significativamente maiores que os que receberam uma dose semelhante ou acima de 0,16 mg/kg/dia [87,5 (50-100) em comparação com 75 (15,63-100), p = 0,006]. Conclusões: Escores reduzidos nos domínios físico, emocional e escolar foram observados em pacientes pediátricos com hepatite autoimune em comparação com pacientes do grupo de controle. Dor abdominal e dose de corticosteroide influenciaram negativamente a qualidade de vida relacionada à saúde em crianças e adolescentes com hepatite autoimune.

ABSTRACT

OBJECTIVE: The aim of this research was to compare language development (expressive and receptive skills) in children awaiting liver transplantation with that of children who have already undergone the surgical procedure. METHODS: An observational, descriptive, cross-sectional study was conducted with 76 children divided into groups, as follows: 31 children who were candidates for liver transplantation (Group 1; G1), 45 children who had already undergone liver transplantation (Group 2; G2), and a control group (CG) of 60 healthy, normally developing children. Health status information was gathered, and the Test of Early Language Development (TELD)-3 was used to assess language skills. Family household monthly income data were also gathered using a specific questionnaire. RESULTS: G1 had poorer language performance compared with G2 and the CG. G2 had lower language performance when compared with the CG. However, when considering the TELD-3 standard scores, G2 had scores within normal limits. The regression analysis indicated age as a risk factor for language deficits in Group 1 and family income as a risk factor for language deficits in G2. CONCLUSIONS: The results suggested that children with chronic liver disease have delays in language development. Transplanted children have linguistic performance within normal limits, but their scores tended to be lower than the CG.

ABSTRACT

ABSTRACT The prevalence of obesity-related metabolic syndrome has rapidly increased in Brazil, resulting in a high frequency of nonalcoholic fatty liver disease, that didn't receive much attention in the past. However, it has received increased attention since this disease was identified to progress to end-stage liver diseases, such as cirrhosis and hepatocellular carcinoma. Clinical practice guidelines for the diagnosis and treatment of nonalcoholic fatty liver disease have not been established in Brazil. The Brazilian Society of Hepatology held an event with specialists' members from all over Brazil with the purpose of producing guideline for Nonalcoholic Fatty Liver Disease based on a systematic approach that reflects evidence-based medicine and expert opinions. The guideline discussed the following subjects: 1-Concepts and recommendations; 2-Diagnosis; 3-Non-medical treatment; 4-Medical treatment; 5-Pediatrics - Diagnosis; 6-Pediatrics - Non-medical treatment; 7-Pediatrics - Medical treatment; 8-Surgical treatment.


RESUMO A prevalência de obesidade relacionada à síndrome metabólica tem crescido no Brasil, que implicou em uma maior frequência de doença hepática gordurosa não alcoólica, não havia recebido muita atenção no passado. Contudo, essa atenção tem merecido interesse cada vez maior desde que se observou o elevado potencial de progressão para formas mais graves dessa doença como cirrose e carcinoma hepatocelular. No Brasil ainda não havia sido proposta nenhuma diretriz para orientar o diagnóstico e tratamento da doença hepática gordurosa não alcoólica. A Sociedade Brasileira de Hepatologia realizou então um evento que reuniu especialistas de todo o Brasil com o objetivo de propor uma diretriz para a doença hepática gordurosa não alcoólica baseada em evidências científicas e opiniões de especialistas nesse tema. A diretriz final é composta dos seguintes temas: 1-Conceitos e recomendações; 2-Diagnóstico; 3-Tratamento não medicamentoso; 4-Tratamento medicamentoso; 5-Diagnóstico em Pediatria; 6-Tratamento não medicamentoso em Pediatria; 7-Tratamento medicamentoso em Pediatria; 8-Tratamento cirúrgico.

ABSTRACT

ABSTRACT In order to draw evidence-based recommendations concerning the management of autoimmune diseases of the liver, the Brazilian Society of Hepatology has sponsored a single-topic meeting in October 18th, 2014 at São Paulo. An organizing committee comprised of seven investigators was previously elected by the Governing Board to organize the scientific agenda as well as to select twenty panelists to make a systematic review of the literature and to present topics related to the diagnosis and treatment of autoimmune hepatitis, primary sclerosing cholangitis, primary biliary cirrhosis and their overlap syndromes. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript organized in topics, followed by the recommendations of the Brazilian Society of Hepatology.

ABSTRACT

Objective: Severe hepatotoxicity caused by paracetamol is rare in neonates. We report a case of paracetamol-induced acute liver failure in a term neonate. Case description: A 26-day-old boy was admitted with intestinal bleeding, shock signs, slight liver enlargement, coagulopathy, metabolic acidosis (pH=7.21; bicarbonate: 7.1mEq/L), hypoglycemia (18mg/dL), increased serum aminotransferase activity (AST=4,039IU/L; ALT=1,087IU/L) and hyperbilirubinemia (total: 9.57mg/dL; direct: 6.18mg/dL) after receiving oral paracetamol (10mg/kg/dose every 4 hours) for three consecutive days (total dose around 180mg/kg; serum concentration 36-48 hours after the last dose of 77µg/ mL). Apart from supportive measures, the patient was successfully treated with intravenous N-acetylcysteine infusion during 11 consecutive days, and was discharged on day 34. The follow-up revealed full recovery of clinical and of laboratory findings of hepatic function. Comments: The paracetamol pharmacokinetics and pharmacodynamics in neonates and infants differ substantially from those in older children and adults. Despite the reduced rates of metabolism by the P-450 CYP2E1 enzyme system and the increased ability to synthesize glutathione - which provides greater resistance after overdoses -, it is possible to produce hepatotoxic metabolites (N-acetyl-p-benzoquinone) that cause hepatocellular damage, if glutathione sources are depleted. Paracetamol clearance is reduced and the half-life of elimination is prolonged. Therefore, a particular dosing regimen should be followed due to the toxicity risk of cumulative doses. This report highlights the risk for severe hepatotoxicity in neonates after paracetamol multiple doses for more than two to three days. .


Objetivo: La hepatotoxicidad grave inducida por el paracetamol es muy rara en neonatos. Se relata el caso de un neonato a término que desarrolló falencia hepática aguda después del uso de paracetamol. Descripción del caso: Niño, 26 días, admitido con sangrado intestinal, señales de choque, discreta hepatomegalia, coagulopatía, acidosis metabólica (pH=7,21; bicarbonato: 7,1mEq/L), hipoglucemia (18mg/dL), aumento de las aminotransferasas séricas (AST=4.039UI/L; ALT=1.087UI/L) e hiperbilirrubinemia (total: 9,75mg/dL; directa: 6,18mg/dL), después del uso de paracetamol por vía oral (10mg/kg/dosis a cada cuatro horas) durante tres días consecutivos (dosis alrededor de 180mg/kg; nivel sérico de 36-48 horas después de la última dosis de 77µg/mL). Además de las medidas de soporte, el paciente fue tratado con N-acetilcisteína (infusión intravenosa continua por 11 días consecutivos), recibiendo alta después de 34 días de internación. El seguimiento mostró recuperación clínica y de los parámetros laboratoriales de la función hepática. Comentarios : La farmacocinética y la farmacodinámica del paracetamol en neonatos y lactantes jóvenes (menores de un año) difieren substancialmente de niños más grandes y adultos. A pesar de que las tasas de metabolismo del sistema enzimático P-450 CYP2E1 están reducidas y la capacidad de generar glutatión, aumentada - confiriendo más protección después de superdosis -, existe la posibilidad de producción de metabólitos hepatotóxicos (N-acetil-pbenzoquinoneimina) que determinan lisis celular, caso se agoten las reservas de glutatión. La depuración es reducida y la media vida de la eliminación, alargada, recomendándose posología distinta por el riesgo de toxicidad ...


Objetivo: A hepatoxicidade grave induzida pelo paracetamol é muito rara em neonatos. Relata-se o caso de um neonato de termo que desenvolveu falência hepática aguda após o uso de paracetamol. Descrição do caso: Menino, 26 dias, admitido com sangramento intestinal, sinais de choque, discreta hepatomegalia, coagulopatia, acidose metabólica (pH=7,21; bicarbonato: 7,1mEq/L), hipoglicemia (18mg/dL), aumento das aminotransferases séricas (AST=4.039UI/L; ALT=1.087UI/L) e hiperbilirrubinemia (total: 9,57mg/dL; direta: 6,18mg/dL), após uso de paracetamol via oral (10mg/kg/dose a cada quatro horas) por três dias consecutivos (dose total ao redor de 180mg/kg; nível sérico de 36-48 horas após a última dose de 77µg/mL). Além das medidas de suporte, o paciente foi tratado com N-acetilcisteína (infusão intravenosa contínua por 11 dias consecutivos), recebendo alta após 34 dias de internação. O seguimento mostrou recuperação clínica e dos parâmetros laboratoriais da função hepática. Comentários: A farmacocinética e a farmacodinâmica do paracetamol em neonatos e lactentes jovens (menores de um ano) diferem substancialmente de crianças maiores e adultos. Apesar de as taxas de metabolismo do sistema enzimático P-450 CYP2E1 estarem diminuídas e a capacidade de gerar glutationa, aumentadas - conferindo maior proteção após superdosagens -, existe a possibilidade de produção de metabólitos hepatotóxicos (N-acetil-p-benzoquinoneimina) que determinam lise celular, caso se esgotem as reservas de glutationa. A depuração é diminuída e a meia-vida de eliminação é prolongada, recomendando-se posologia distinta pelo risco de toxicidade de doses cumulativas. O presente relato destaca o risco de hepatotoxicidade grave ...

ABSTRACT

INTRODUCTION:The objectives of this study were evaluate hepatitis B virus (HBV) serological markers in children and adolescents followed up at the Child Institute of the Hospital das Clínicas, Faculdade de Medicina de São Paulo, Universidade de São Paulo; identify chronic HBV carriers and susceptible individuals in the intrafamilial environment; characterize HBV genotypes; and identify mutations in the patients and household contacts. METHODS: Ninety-five hepatitis B surface antigen-positive children aged <19 years and 118 household contacts were enrolled in this study. Commercial kits were used for the detection of serological markers, and PCR was used for genotyping. RESULTS: Hepatitis B e antigen (HBeAg) was detected in 66.3% (63/95) of cases. Three of the 30 HBeAg-negative and anti-HBeAg-positive patients presented with precore mutations and 11 presented with mutations in the basal core promoter (BCP). Genotype A was identified in 39 (43.8%) patients, genotype D in 45 (50.6%), and genotype C in 5 (5.6%). Of the 118 relatives, 40 were chronic HBV carriers, 52 presented with the anti-HBc marker, 19 were vaccinated, and 7 were susceptible. Among the relatives, genotypes A, D, and C were the most frequent. One parent presented with a precore mutation and 4 presented with BCP mutations. CONCLUSIONS: Genotypes A and D were the most frequent among children, adolescents, and their relatives. The high prevalence of HBV in the families showed the possibility of its intrafamilial transmission.


INTRODUÇÃO: Os objetivos deste estudo foram: avaliar os marcadores sorológicos nas crianças e adolescentes acompanhadas no Instituto da Criança do Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP); identificar portadores crônicos do VHB e indivíduos suscetíveis no ambiente intrafamiliar; caracterizar o genótipo do VHB; observar a presença de cepas mutantes entre os pacientes e familiares estudados. MÉTODOS: Noventa e cinco crianças e adolescentes positivas para o antígeno de superfície do vírus da Hepatite B (AgHBs), menores de 19 anos, e 118 familiares foram envolvidos neste estudo. Foram utilizados kits comerciais para a pesquisa dos marcadores sorológicos e a PCR foi utilizada para genotipagem. RESULTADOS: O antígeno e do vírus da hepatite B (AgHBe) foi detectado em 66,3% (63/95) dos casos. Três dos 30 pacientes AgHBe negativo e anti-HBe positivo apresentaram mutação na região pré-core e 11 na região BCP. Em 39 (43,8%) pacientes, foi identificado o genótipo A, 45 (50,6%)o genótipo D e cinco (5,6%) o genótipo C. Dos 118 familiares estudados, 40 eram portadores crônicos do VHB, 52 tinham marcador sorológico de contato prévio e sete eram suscetíveis. Dentre os familiares AgHBs positivos, os genótipos A, D e C foram os mais frequentes. Um familiar apresentou mutação na região pré-core e quatro apresentaram mutação na região do BCP. CONCLUSÕES: Os genótipos A e D foram os mais frequentes dentre as crianças adolescentes e seus familiares. Alta frequência do VHB nos familiares mostrou a possibilidade de transmissão intrafamiliar.

ABSTRACT

OBJECTIVES: Clinical-laboratory and evolutionary analysis of twenty-eight patients with Wilson's disease. METHODS: Twenty-eight children (twelve females and sixteen males) with Wilson's disease were evaluated retrospectively between 1987 and 2009, with a follow-up of 72 months (1 - 240 months). The clinical, laboratory, and histologic features at diagnosis were recorded at the end of the study. RESULTS: The median age at diagnosis was 11 years (2 - 18 years). Twelve patients were asymptomatic, seven had hepatitis symptoms, five had raised aminotransferase levels, three had hepatomegaly associated with neurological disorders, one had fulminant hepatitis with hemolytic anemia, and six patients presented with a Kayser-Fleischer ring. A histological analysis revealed that six children had chronic hepatitis, seven had cirrhosis, two had steatosis, one had portal fibrosis, and one had massive necrosis. The treatment consisted of D-penicillamine associated with pyridoxine for 26 patients. Adverse effects were observed in the other two patients: one presented with uncontrollable vomiting and the other demonstrated elastosis perforans serpiginosa. At the end of the study, all 26 treated patients were asymptomatic. Twenty-four of the patients were treated with D-penicillamine and pyridoxine, and two were treated with trientine and zinc sulfate. A liver transplant was performed in one patient with fulminant hepatitis, but the final patient died 48 hours after admission to the intensive care unit. CONCLUSIONS: Family screenings associated with early treatment are important in preventing Wilson's disease symptoms and potentially fatal disease progression. The study suggests that Wilson's disease must be ruled out in children older than two years presenting with abnormal levels of hepatic enzymes because of the heterogeneity of symptoms and the encouraging treatment results obtained so far.

ABSTRACT

Objetivo: Avaliar as características epidemiológicas, clínicas e prognósticas de crianças com atresia biliar. Método: Dados sobre portoenterostomia, transplante hepático (TxH), idade no último seguimento e sobrevida foram coletados dos prontuários de pacientes acompanhados em seis centros no Brasil (1982-2008) e comparados em relação às décadas do procedimento cirúrgico. Resultados: Dos 513 pacientes, 76,4% foram submetidos a portoenterostomia [idade: 60,0-94,7 (82,6±32,8) dias] e 46,6% foram submetidos a TxH. Em 69% dos casos, o TxH foi realizado após a portoenterostomia, enquanto em 31% dos casos o TxH foi realizado como cirurgia primária. Os pacientes da região Nordeste foram submetidos a portoenterostomia mais tardiamente do que as crianças das regiões Sul (p = 0,008) e Sudeste (p = 0,0012), embora, mesmo nas duas últimas regiões, a idade no momento da portoenterostomia tenha sido superior ao desejável. Ao longo das décadas, houve aumento progres si vo do número de TxH realizados. A sobrevida global foi de 67,6%. A sobrevida aumentou nas últimas décadas (anos 1980 versus 90, p = 0,002; anos 1980 versus 2000, p < 0,001; anos 1990 versus 2000, p < 0,001). A sobrevida de 4 anos pós-portoenterostomia, com ou sem TxH, foi de 73,4%, inversamente correlacionada à idade no momento da portoenterostomia (80,77,7,60,5% para < 60,61-90, > 90 dias, respectivamente). Os pacientes transplantados apresentaram taxas de sobrevida mais elevadas (88,3%). A sobrevida de 4 anos com fígado nativo foi de 36,8%, inversamente correlacionada à idade no momento da portoenterostomia (54, 33,3, 26,6% para < 60,61-90, > 90 dias, respectivamente). Conclusões: Este estudo multicêntrico demonstrou que o encaminhamento tardio das crianças portadoras de atresia biliar ainda é um problema no Brasil, influenciando a sobrevida destes pacientes. Estratégias que proporcionam o encaminhamento precoce estão sendo desenvolvidas com o objetivo de reduzir a necessidade de transplante hepático nos primeiros anos de vida.


Objective: To evaluate epidemiological, clinical and prognostic characteristics of children with biliary atresia. Methods: Data regarding portoenterostomy, liver transplantation (LTx), age at last follow-up and survival were collected from the records of patients followed up in six Brazilian centers (1982-2008) and compared regarding decades of surgery. Results: Of 513 patients, 76.4% underwent portoenterostomy [age: 60-94.7 (82.6±32.8) days] and 46.6% underwent LTx. In 69% of cases, LTx followed portoenterostomy, whereas in 31% of cases LTx was performed as the primary surgery. Patients from the Northeast region underwent portoenterostomy later than infants from Southern (p = 0.008) and Southeastern (p = 0.0012) Brazil, although even in the latter two regions age at portoenterostomy was higher than desirable. Over the decades, LTx was increasingly performed. Overall survival was 67.6%. Survival increased over the decades (1980s vs. 1990s, p = 0.002; 1980s vs. 2000s, p < 0.001; 1990s vs. 2000s, p < 0.001). The 4-year post portoenterostomy survival, with or without LTx, was 73.4%, inversely correlated with age at portoenterostomy (80, 77.7, 60.5% for < 60, 61-90, > 90 days, respectively). Higher survival rates were observed among transplanted patients (88.3%). The 4-year native liver survival was 36.8%, inversely correlated with age at portoenterostomy (54, 33.3, 26.6% for < 60, 61-90, > 90 days, respectively). Conclusions: This multicenter study showed that late referral for biliary atresia is still a problem in Brazil, affecting patient survival. Strategies to enhance earlier referral are currently being developed aiming to decrease the need for liver transplantation in the first years of life.

ABSTRACT

CONTEXT AND OBJECTIVE: Viral hepatitis A is still a concern at public health level in Brazil and around the world, due both to the number of affected subjects and the possibility of complications in the acute forms. The Brazilian Ministry of Health estimates that at least 70% of this country's population has already had contact with the hepatitis A virus (HAV). The aim here was to discover the prevalence of serological markers for the hepatitis A virus among children and teenagers at daycare facilities, kindergartens and elementary schools in the city of Santos. DESIGN AND SETTING: Cross-sectional study in kindergartens and elementary schools within the municipal education network in several regions of the city of Santos. METHOD: Students' family members were surveyed using a questionnaire and 4,680 finger-prick blood samples were taken and assayed by means of the ELISA technique. RESULTS: The general prevalence of anti-HAV IgG was 9.72% and, of these cases, 74.6% were reactive to anti-HAV IgM. There was higher prevalence of anti-HAV IgG among older children, females, children who played in streams, those whose homes were not connected to the sewage system, those whose parents had low education levels, those with low household income and those who did not live along the seashore. The prevalence of anti-HAV IgM peaked in the early years and subsequently fell, and it was lower on the hills and in the Northwestern Zone. CONCLUSION: The general prevalence of serological markers for hepatitis A was low in Santos.


CONTEXTO E OBJETIVO: A hepatite viral A continua sendo uma preocupação em nível de saúde pública no Brasil e no mundo, tanto pelo número de indivíduos atingidos, como pela possibilidade de complicação das formas agudas. O Ministério da Saúde estima que pelo menos 70% da população do Brasil já tiveram contato com o vírus da hepatite A. O objetivo foi conhecer a prevalência de marcadores sorológicos do vírus da hepatite A em crianças e adolescentes de creches e escolas de ensino infantil e fundamental na cidade de Santos. TIPO DE ESTUDO E LOCAL: Estudo transversal em pré-escolas e de ensino fundamental da rede municipal em diversas regiões da cidade de Santos. MÉTODO: Foi aplicado um questionário aos familiares dos estudantes e coletadas 4.680 amostras de sangue através de punção capilar para realização da sorologia pela técnica ELISA. RESULTADOS: A prevalência geral do anti-HVA IgG foi de 9,72% e, desses, 74,6% foram anti-HVA IgM reagentes. A prevalência de anti-HVA IgG foi maior entre as crianças mais velhas, meninas, aquelas que brincavam em córregos, sem rede de coleta de esgoto em sua moradia, de pais com baixa instrução, de baixa renda familiar e aquelas que não eram moradoras da orla. A prevalência de anti-HVA IgM teve pico nos primeiros anos e posterior queda e, no morro e Zona Noroeste, foi mais baixa. CONCLUSÃO: A prevalência geral dos marcadores sorológicos para hepatite A foi baixa em Santos.

ABSTRACT

A encefalopatia hepática (EH) é um distúrbio funcional do sistema nervoso central (SNC) associado à insufi ciência hepática, de fisiopatologia multifatorial e complexa. Devido aos avanços no conhecimento sobre o manejo da EH na cirrose e na insuficiência hepática aguda (IHA), a diretoria da Sociedade Brasileira de Hepatologia (SBH) promoveu uma reunião monotemática acerca da fi siopatologia, diagnóstico e tratamento da EH, abordando aspectos controversos relacionados ao tema. Com a utilização de sistemática da medicina baseada em evidências, foram abordados o manejo da EH e da hipertensão intracraniana na IHA, o manejo da EH episódica na cirrose, as controvérsias no manejo da EH e a abordagem da EH mínima. O objetivo desta revisão é resumir os principais tópicos discutidos na reunião monotemática e apresentar recomendações sobre o manejo da síndrome votadas pelo painel de expertos da SBH.


Hepatic encephalopathy (HE) is a functional disorder of the central nervous system (CNS) associated with liver failure, either end-stage chronic liver disease or fulminant hepatic failure. Its pathogenesis remains complex and poorly understood. In view of recent advances in the management of HE, the Brazilian Society of Hepatology endorsed a monothematic meetingregarding HE in order to gather experts in the to discuss related data and to draw evidence-based recommendations concerning: management of HE and intracranial hypertension in FHF, treatment of episodic HE in cirrhosis, controversies in the management of EH including difficult to treat cases and diagnostic and treatment challenges for minimal HE. The purpose of this review is to summarize the lectures and recommendations made by the panel of experts of the Brazilian Society of Hepatology.

ABSTRACT

No dia 05 de agosto de 2010, no Hotel Blue Tree, no bairro do Morumbi em São Paulo, a Sociedade Brasileira de Hepatologia realizou uma reunião de expertos para discutir alguns assuntos importantes referentes à toxicidade hepática. Esta reunião foi de responsabilidade exclusiva da Sociedade Brasileira de Hepatologia (SBH), sem interferência de agências ou da indústria farmacêutica. Dentre os assuntos discutidos, três deles mereceram destaque pelo volume de solicitações de esclarecimentos encaminhadas diretamente à Sociedade Brasileira de Hepatologia. O site da SBH recebe com frequência tais solicitações de outras sociedades ou diretamente de colegas, assim como do público não-médico, por questões pertinentes a estes assuntos: 1. papel do acetaminofen/paracetamol nas alterações hepáticas da dengue; 2. eficácia e segurança da medicina alternativa (homeopatia, medicina natural, fitoterápicos); 3. alterações hepáticas induzidas por analgésicos, antitérmicos e anti-inflamatórios não-esteroides com foco no seu uso na dengue.Dentro deste contexto, a Sociedade Brasileira de Hepatologia organizou uma sessão durante todo o dia 05 de agosto para discutir unicamente estes temas.

ABSTRACT

OBJETIVO: Descrever o perfil genético e metabólico de portadores da síndrome de Berardinelli-Seip (BSCL) acompanhados no Instituto da Criança do HC-FMUSP. SUJEITOS E MÉTODOS: Pacientes com as características clínicas da BSCL (n = 5), todas do sexo feminino, foram avaliadas com dosagens de glicose e insulina, lípides, leptina, enzimas hepáticas, análise de DNA, ultrassonografia abdominal. RESULTADOS: A deficiência de leptina e a hipertrigliceridemia foram constatadas nas cinco pacientes. Três evoluíram para diabetes melito (DM). Quatro tiveram mutação no gene AGPAT2 e uma no gene CAV1. CONCLUSÃO: As alterações metabólicas mais precoces foram a hipertrigliceridemia e a resistência insulínica, culminando no surgimento do DM à época da puberdade, sendo as mutações no gene AGPAT2 as mais frequentes em nossa casuística.


OBJECTIVE: To report the genetic and metabolic profile of patients with Berardinelli-Seip syndrome (BSCL) followed at Instituto da Criança, HC-FMUSP. SUBJECTS AND METHODS: Patients with clinical features of BSCL (n = 5), all female, were evaluated through serum levels of glucose, insulin, lipids, leptin, and liver enzymes. Abdominal sonography and DNA analysis were also performed. RESULTS: Leptin deficiency and hypertriglyceridemia were found in all the patients. Three progressed to diabetes mellitus. Four patients have mutations in AGPAT2 gene and one have a mutation in CAV1 gene. CONCLUSION: The earliest metabolic abnormalities were hypertriglyceridemia and insulin resistance, culminating in the onset of diabetes at the time of puberty. Mutations in the AGPAT2 gene were the most frequent in our patients.
