The first five-year evaluation of cystic fibrosis neonatal screening program in São Paulo State, Brazil.

The Hospital of the Ribeirão Preto Medical School, University of São Paulo is one of the three screening centers in São Paulo State, Brazil, and has included a test for cystic fibrosis (CF) since February 6, 2010, by a court order. We evaluated the first five years of this CF-newborn screening program. The original immunoreactive trypsinogen (IRT)/IRT screening protocol was adopted in Brazil. A total of 173,571 newborns were screened, 1,922 (1.1%) of whom showed IRT1 ≥ 70ng/mL. Of these, 1,795 (93.4%) collected IRT2, with elevated results (IRT2 ≥ 70ng/mL) in 102 of them (5.2%). We identified a total of 26 CF cases during this period, including three CF cases that were not detected by the CF-newborn screening. The incidence of the disease among the screened babies was 1:6,675 newborns screened. Median age at the initial evaluation was 42 days, comparable to that of neonates screened with the IRT/DNA protocol. Almost all infants with CF already exhibited some manifestations of the disease during the neonatal period. The mutation most frequently detected in the CF cases was F508del. These findings suggest the early age at the beginning of treatment at our center was due to the effort of the persons involved in the program regarding an effective active search. Considering the false negative results of CF-newborn screening and the early onset of clinical manifestations of the disease in this study, pediatricians should be aware of the diagnosis of CF even in children with negative test.

O estudo avalia os primeiros cinco anos desse programa de triagem neonatal da FC. O Brasil adota o protocolo de triagem original, com o tripsinogênio imunorreativo (IRT)/IRT. Foram triados um total de 173.571 recém-nascidos, dos quais 1.922 (1,1%) mostraram IRT ≥ 70ng/mL. Destes, 1.795 (93,4%) tiveram amostras coletadas para IRT2, com resultados elevados (IRT2 ≥ 70ng/mL) em 102 deles (5,2%). Identificamos um total de 26 casos de FC durante esse período, inclusive 3 casos de FC que não foram detectados com a triagem neonatal. A incidência da FC foi de 1 caso em cada 6.675 recém-nascidos triados. A idade mediana na avaliação inicial foi 42 dias, comparável à idade de recém-nascidos triados com o protocolo IRT/DNA. Quase todos os lactentes com FC já exibiam algumas manifestações da doença durante o período neonatal. A mutação mais comum nos casos de FC foi a F508del. Os resultados em nosso centro indicam que a idade precoce no início do tratamento foi devido aos esforços do programa na implementação de uma busca ativa eficaz. Considerando os resultados falsos-negativos no programa de triagem neonatal para FC e o início precoce das manifestações clínicas da doença neste estudo, os pediatras devem estar cientes da possibilidade de diagnóstico de FC, mesmo em crianças com teste negativo.

Autoimmune hepatitis in 828 Brazilian children and adolescents: clinical and laboratory findings, histological profile, treatments, and outcomes / Hepatite autoimune em 828 crianças e adolescentes brasileiros: achados clínicos e laboratoriais, perfil histológico, tratamentos e resultados

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.

Evaluation of nonalcoholic fatty liver disease using magnetic resonance in obese children and adolescents / Avaliação de doença hepática gordurosa não alcoólica utilizando ressonância em crianças e adolescentes obesos

Abstract Objective: To determine the frequency of nonalcoholic fatty liver disease using nuclear magnetic resonance as a noninvasive method. Methodology: This was a cross-sectional study conducted on 50 children and adolescents followed up at an outpatient obesity clinic. The subjects were submitted to physical examination, laboratory tests (transaminases, liver function tests, lipid profile, glycemia, and basal insulin) and abdominal nuclear magnetic resonance (calculation of hepatic, visceral, and subcutaneous fat). Results: Nonalcoholic fatty liver disease was diagnosed in 14 (28%) participants, as a severe condition in eight (percent fat >18%), and as non-severe in four (percent fat from 9% to 18%). Fatty liver was associated with male gender, triglycerides, AST, ALT, AST/ALT ratio, and acanthosis nigricans. Homeostasis model assessment of insulin resistance and metabolic syndrome did not show an association with fatty liver. Conclusion: The frequency of nonalcoholic fatty liver disease in the present population of children and adolescents was lower than that reported in the international literature. It is suggested that nuclear magnetic resonance is an imaging exam that can be applied to children and adolescents, thus representing an effective noninvasive tool for the diagnosis of nonalcoholic fatty liver disease in this age range. However, further national multicenter studies with longitudinal design are needed for a better analysis of the correlation between nonalcoholic fatty liver disease and its risk factors, as well as its consequences.

Resumo Objetivo: Determinar a frequência da doença hepática gordurosa não alcoólica utilizando ressonância magnética nuclear como um método não invasivo. Metodologia: Este foi um estudo transversal realizado em 50 crianças e adolescentes acompanhadas em uma Clínica Ambulatorial de Obesidade. Os indivíduos foram submetidos a exame físico, testes de laboratório (transaminases, testes de função hepática, perfil lipídico, glicemia e insulina basal) e ressonância magnética nuclear abdominal (cálculo da gordura hepática, visceral e subcutânea). Resultados: A doença hepática gordurosa não alcoólica foi diagnosticada em 14 (28%) participantes, como uma condição grave em oito (percentual de gordura > 18%) e não grave em quatro (percentual de gordura de 9 a 18%). Fígado gorduroso foi associado a sexo masculino, triglicerídeos, aspartato aminotransferase (AST), alanina aminotransferase (ALT), proporção de AST/ALT e acanthosis nigricans. O Modelo de Avaliação da Homeostase de Resistência à Insulina e a síndrome metabólica não mostraram associação com fígado gorduroso. Conclusão: A frequência da doença hepática gordurosa não alcoólica na população atual de crianças e adolescentes foi inferior à relatada na literatura internacional. Sugerimos que a ressonância magnética nuclear seja um exame de imagem que pode ser aplicado em crianças e adolescentes, representando, assim, uma ferramenta não invasiva eficaz no diagnóstico de doença hepática gordurosa não alcoólica nessa faixa etária. Contudo, estudos multicêntricos nacionais adicionais de modelo longitudinal são necessários para uma melhor análise da correlação entre a doença hepática gordurosa não alcoólica e seus fatores de risco, bem como suas consequências.

Assessing the proposed association between DED and gluten-free diet introduction in celiac children.

A strong association between celiac disease (CD) and dental enamel defects (DEDs) have been extensively reported, however, the nature of this relationship is still unclear. The aim of this study was to evaluate DEDs phenotype in CD individuals according to the time they were introduced to a gluten-free diet (GFD). Forty-five CD individuals were examined by a pediatric dentist. DEDs were classified according to the type of affected teeth. CD individuals were classified into two groups (with or without DEDs) and the differences between these groups were tested using chi-square or Fisher´s exact tests and t-test to compare differences between means. The Pearson coefficient test was used to evaluate the degree of the correlation between the age of GFD introduction and number of affected teeth. Individuals with MIH were introduced earlier to the GFD (p = 0.038). An association was also observed for molar DED (p = 0.013). In conclusion, our study suggested an association between a specific type of DED and the time that CD individuals were introduced to a GFD.

Nutritional status of adolescents with cystic fibrosis treated at a reference center in the southeast region of Brazil.

BACKGROUND: Several factors can interfere with the full physical and emotional growth of adolescents, among them chronic diseases. The aim was to determine the nutritional status of adolescents and to associate it with puberty, pancreatic sufficiency, lung function and age range of Cystic Fibrosis (CF) diagnosis. METHODS: An observational, cross-sectional, retrospective and analytical study was conducted using the data of medical records. SETTING: Reference center in the northeastern region of the state of São Paulo - Brazil. PATIENTS: All adolescents with CF attended in 2010 were included. Some variables included: pancreatic sufficiency (steatocrit >2 %), pancreatic enzymes replacement (yes/no), pubertal status-Tanner criteria (prepubertal: M1/G1, pubertal: M2/G2 to M4/G4, postpubertal: M5/G5), age at CF diagnosis (<2 and ≥2 years of age), Lung function, measured as a predicted forced expiratory volume in 1 s (FEV1). Main outcome measures Nutritional indicators: body mass index for age (BMI/A) and height for age (H/A) with z-score calculated with Anthro Plus software. Cut-off reference points: ≥ z-score -3 and < z-score -2 (thinness); z-score -2 and ≤ z-score-z +1 (normal weight); >z-score +1 (overweight or obesity), and z-score <-2 (low or very low H/A). The groups were compared by the Kruskal-Wallis test. Level of significance: p<0.05. RESULTS: Thirty adolescents. Median (min;max) age: 14.4 (10.1;19.8) years. BMI/A and H/A z-score, respectively: early diagnosis of CF (-0.8; -1.1) or late diagnosis of CF (-0.5;-0.8); with pancreatic insufficiency (-0.7; -0.8) or without pancreatic insufficiency (-0.8; -0.5) and prepubertal (-0.8; -0.7) pubertal (-0.2; -1.5) or postpubertal (-0.7; -0.5). No significant difference (p>0.05) was observed. Patients with and without pancreatic insufficiency, presented H/A borderline z-score (p=0.05). Association between H/A and FEV1 was borderline (p=0.05). CONCLUSIONS: Adolescents presented adequate nutritional status, although with slightly lower values than those of developed countries. FEV1 lower levels occurred more frequently in adolescents with low H/A.

Early manifestations of cystic fibrosis in a premature patient with complex meconium ileus at birth / Manifestações precoces da fibrose cística em paciente prematuro com íleo meconial complexo ao nascimento

OBJECTIVE: To report a case of a preterm infant with complex meconium ileus at birth and cystic fibrosis. CASE DESCRIPTION: A male infant was born by vaginal delivery at 33 weeks and 5 days of gestational age with respiratory distress and severe abdominal distension. The exploratory laparotomy in the first day of life identified meconium ileus and secondary peritonitis. Ileal resection and ileostomy were performed, followed by reconstruction of the bowel transit at 20 days of life. At 11 days of life, the first immunoreactive trypsinogen (IRT) was 154 ng/mL (reference value = 70), and oral pancreatic enzymes replacement therapy was started. After 23 days, the second IRT was 172ng/mL (reference value = 70). At 35 days of age he was discharged with referrals to primary care and to a special clinic for CF for the determination of sweat chloride. He was received in the outpatient clinic for neonatal screening for CF at 65 days of life presenting malnutrition and respiratory distress. The sweat chloride test was performed, with a positive result (126mEq/L). COMMENTS: This case illustrates the rapid evolution of CF in a premature patient with complex meconium ileus as the first clinical manifestation.

OBJETIVO: Relatar o caso de um recém-nascido prematuro com íleo meconial complexo e fibrose cística. DESCRIÇÃO DO CASO: Recém-nascido do sexo masculino nasceu de parto vaginal com 33 semanas e cinco dias de idade gestacional e apresentou desconforto respiratório e distensão abdominal grave. Foi submetido à laparotomia exploratória no primeiro dia de vida e identificado íleo meconial com peritonite secundária. Foram feitas ressecção ileal e ileostomia, com reconstrução do trânsito intestinal aos 20 dias de vida. Com 11 dias de idade, a primeira dosagem sérica de tripsina imunorreativa (TIR) foi 154ng/mL (valor de referência = 70) e optou-se pelo início da terapia de reposição oral de enzimas pancreáticas. Após 23 dias, a segunda TIR foi 172ng/mL (valor de referência = 70). Recebeu alta com 35 dias de vida com encaminhamentos à rede básica de saúde e ao serviço de referência para a detecção de fibrose cística. Foi atendido no ambulatório de triagem neonatal para fibrose cística aos 65 dias de vida e apresentava desnutrição e desconforto respiratório. O resultado do teste do cloro no suor foi positivo (126 mEq/L). COMENTÁRIOS: O caso ilustra a rápida evolução da fibrose cística em um paciente prematuro com íleo meconial complexo como primeira manifestação clínica.

Oral aspects in celiac disease children: clinical and dental enamel chemical evaluation.

OBJECTIVE: The aim of this study was to evaluate the oral manifestations of celiac disease (CD), the chemical composition of dental enamel, and the occurrence of CD in children with dental enamel defects (DEDs). STUDY DESIGN: In the study, 52 children with CD and 52 controls were examined for DEDs, recurrent aphthous stomatitis (RAS), dental caries experience, and salivary parameters. In addition, 10 exfoliated primary enamel molars from each group were analyzed by energy dispersive x-ray spectroscopy and Fourier transform infrared spectroscopy. Fifty children with DEDs were submitted to CD diagnosis. RESULTS: Among the children with CD, a higher prevalence of DEDs (P = .00001) and RAS (P = .0052), lower caries experience (P = .0024), and reduction of salivary flow (P = .0060) were observed. Dental enamel from the children with CD demonstrated a lower calcium-to-phosphorus ratio (P = .0136), but no difference in the carbonate-to-phosphate ratio (P = .5862) was observed. In the multivariate analysis, CD was a protective factor for caries (OR = 0.74) and a risk factor for RAS (OR3.23). CONCLUSIONS: The children with CD presented with more RAS, DEDs, reduction of salivary flow, and chemical alterations in the enamel.

Hepatoportal sclerosis and extrahepatic portal venous obstruction associated with anti-phospholipid antibody syndrome in child.

Erros inatos do metabolismo confirmados no Hospital das Clínicas de Ribeirão Preto-SP no período de 2000 a 2008 / Inborn errors of metabolism in the Hospital of Clinics of Ribeirão Preto - SP from 2000 to 2008

Os Erros Inatos do Metabolismo (EIM) vêm sendo cada vez mais identificados nos últimos anos. A preocupação com o diagnóstico precoce decorre do foco na prevenção de deficiências, especialmente a mental. Este estudo descritivo teve por objetivo verificar diagnósticos confirmados e modalidades de tratamento utilizadas de janeiro de 2000 a dezembro de 2008. Método: foi realizada busca ativa de casos confirmados nos serviços que atendem esse tipo doença: neurologia (neuropediatria e doençasneuromusculares), pediatria (serviço de gastrologia e hepatologia) e genética clínica, além de levantamento no Serviço de Arquivo Médico do HCFMRP-USP. Foram confirmados 165 pacientes com EIM, com idades de um dia a 22 anos (mediana de um ano); 50 casos foram defeitos na síntese ou catabolismo de moléculas complexas, 65 no metabolismo intermediário, e 50 na produção ou utilização de energia. O tratamento foi instituído para 12 dos 50 pacientes do grupo I sendo reposição enzimática em 11 e transplante de medula óssea em um; todos do grupo II e III receberam orientação nutricional; 60 do grupo II receberam fórmula dietética industrializada; dos 50 do grupo III, 43 com mitocondriopatias receberam L-carnitina e coenzimas e aqueles com glicogenose, orientação sobre aporte de carbohidratos. A formação de novos recursos humanos, integração com a Rede EIM Brasil e linhas de pesquisa na área são prioridades para melhorar a acuidade na detecção e tratamento de erros inatos do metabolismo.

Inborn Errors of Metabolism have been increasingly identified in recent years. The early diagnosis focuses on prevention of disabilities, especially mental retardation. This descriptive study aims to verify confirmed diagnosis and treatment modalities in HCFMRP-USP cases from January of 2000 to December of 2008. A total of 165 patients with ages ranging from one day to 22 years (median one year) were detected. Fifty patients had synthesis or catabolism of complex molecules (group I), 65 intermediary metabolism (group II), and 50 had production or use of energy (group III) defects. Among the patients of group I, 11 had enzyme replacement therapy, and one bone marrow transplantation; for group II and III, inaddition to daily nutritional guidance for all of the patients, 60 from group II received industrialized diets; from group III, 43 with mitochondrial diseases received L-carnitine and coenzymes, and those with glycogenosis were focused mainly on the intake of carbohydrates. New human resources, integration with the Network EIM Brazil and lines of research in the area are priorities for improving the accuracy in the detection and treatment of inborn errors of metabolism.
