RESUMO

OBJECTIVE: To compare endoscopic and histologic features of pediatric patients with eosinophilic esophagitis (EoE) responding to proton pump inhibitor (PPI) to those not responding to PPI. METHODS: Endoscopic reports and photographs of patients with symptoms of esophageal dysfunction and ≥15 eosinophils per high-powered field (eos/hpf) in esophageal biopsies prior to PPI trial were reviewed. Patients were classified as responsive to PPI (PPIREoE) or non-responsive to PPI (PPINREoE) according to response to treatment (<15 eos/hpf) at second endoscopy after 8 weeks. RESULTS: Of the 231 patients (72.3% male) enrolled, 64 (27.7%) were PPI responsive. Edema (77.3% vs. 62.5%, p=0.031) and furrows (69.5% vs. 51.6%, p=0.014) at endoscopy were more frequent in patients not responding to PPI. Higher peak eosinophil count (≥35 eos/hpf) in the middle esophagus (25.1% vs. 12.5%) was more frequent in the group not responding to PPI (p=0.001). Patients with <15 eos/hpf in the middle esophagus at first endoscopy were more likely to respond to treatment with PPI when compared to patients with 15-34 eos/hpf (p=0.004; OR: 3.26; CI 95%: 1.46 - 7.24) and to patients with ≥ 35 eos/hpf (p=0.006; OR: 3.20; CI 95%: 1.39 - 7.41). CONCLUSION: Edema and furrows at endoscopy and higher peak eosinophil counts in the middle esophagus were significantly more frequent in the group not responding to PPI. Once there were no significant differences in other features between groups it is not possible to differentiate patients with PPIREoE from patients with PPINREoE based on endoscopic and histologic findings.

RESUMO

Anaphylaxis is a severe, life-threatening generalized or systemic hypersensitivity reaction that requires rapid and adequate care. This study aimed to obtain an integrated view of the level of physicians' knowledge related with treatment of anaphylaxis in studies published within the last 5 years. Sixteen studies were found and four points were identified as of the great interest to the authors: (1) emergency pharmacological treatment, (2) epinephrine auto-injectors prescription, (3) knowledge of the main signs of anaphylaxis, and (4) admission of the patient to verify biphasic reactions. Concern about the use of intramuscular adrenaline as the first choice in relation with anaphylaxis was evident in most studies, rather than its use in the comparison dial, and especially low in a study that included data from Brazil, in which the frequency of its use was 23.8%. An adrenaline autoinjector is highly recommended among specialists for patients at risk of anaphylaxis, however, its use is still infrequent among non-specialists and in countries that this agent is not available. Intervention studies have shown improved medical knowledge of anaphylaxis following disclosure of the information contained in the international guidelines. The analysis of these studies reinforces the need to disseminate international guidelines for diagnosis and treatment of anaphylaxis, as well as providing an adrenaline autoinjector, to improve management and to prevent a fatal outcome.

RESUMO Anafilaxia é uma reação de hipersensibilidade generalizada ou sistêmica grave, com risco de morte, que exige atendimento rápido e correto. Este estudo teve como objetivo obter uma visão integrada do nível de conhecimento dos médicos no atendimento da anafilaxia à luz dos estudos publicados internacionalmente nos últimos 5 anos. Foram encontrados 16 estudos, com quatro pontos identificados como de maior interesse dos autores: (1) tratamento farmacológico de emergência, (2) prescrição de autoinjetores de adrenalina, (3) conhecimento dos principais indícios da anafilaxia e (4) observação do paciente para verificar reações bifásicas. A preocupação com o uso da adrenalina intramuscular como primeira escolha frente à anafilaxia foi evidente na maioria dos estudos, mas o conhecimento sobre seu uso se mostrou desigual e especialmente baixo em estudo que incluiu dados do Brasil, onde a frequência de seu uso foi de 23,8%. A adrenalina autoinjetável é altamente recomendada entre especialistas para pacientes em risco de anafilaxia, mas seu uso ainda é pouco frequente entre não especialistas e em países que não dispõem dela em seus mercados internos. Estudos de intervenção comprovaram a melhora no entendimento dos médicos sobre anafilaxia após a divulgação das informações contidas nas diretrizes internacionais. A análise dos estudos reforça a necessidade de disseminar as diretrizes internacionais no manejo da anafilaxia, bem como de disponibilizar a adrenalina autoinjetável, a fim de melhorar o atendimento e evitar um desfecho fatal.

RESUMO

ABSTRACT INTRODUCTION: Allergic rhinitis is considered the most prevalent respiratory disease in Brazil and worldwide, with great impact on quality of life, affecting social life, sleep, and also performance at school and at work. OBJECTIVE: To compare the efficacy and safety of two formulations containing mometasone furoate in the treatment of mild, moderate, or severe persistent allergic rhinitis after four weeks of treatment. METHODS: Phase III, randomized, non-inferiority, national, open study comparing mometasone furoate in two presentations (control drug and investigational drug). The primary endpoint was the percentage of patients with reduction of at least 0.55 in nasal index score (NIS) after four weeks of treatment. Secondary outcomes included total nasal index score score after four and 12 weeks of treatment; individual scores for symptoms of nasal obstruction, rhinorrhea, sneezing, and nasal pruritus; as well as score for pruritus, lacrimation, and ocular redness after four and 12 weeks of treatment. The study was registered at clinicaltrials.gov with the reference number NCT01372865. RESULTS: The efficacy primary analysis demonstrated non-inferiority of the investigational drug in relation to the control drug, since the upper limit of the confidence interval (CI) of 95% for the difference between the success rates after four weeks of treatment (12.6%) was below the non-inferiority margin provided during the determination of the sample size (13.7%). Adverse events were infrequent and with mild intensity in most cases. CONCLUSION: The efficacy and safety of investigational drug in the treatment of persistent allergic rhinitis were similar to the reference product, demonstrating its non-inferiority.


Resumo Introdução: A rinite alérgica é considerada a doença respiratória mais prevalente no Brasil e em todo o mundo, com grande impacto na qualidade de vida; além de, afetar a vida social, o sono e também o desempenho na escola e no trabalho. Objetivo: Comparar a eficácia e segurança de duas formulações contendo furoato de mometasona no tratamento da rinite alérgica persistente leve, moderada ou grave por um período de quatro semanas. Método: Trata-se de um estudo nacional aberto de fase III, randomizado, de não inferioridade de comparação do furoato de mometasona em duas apresentações (medicação de controle e fármaco sob investigação). O ponto final primário foi o percentual de pacientes com redução mínima de 0,55 no escore de índice nasal (EIN) após quatro semanas de tratamento. Os desfechos secundários foram: escore NIS total após 4 e 12 semanas de tratamento; escores individuais para sintomas de obstrução nasal, rinorréia, espirros e prurido nasal, bem como escores para prurido, lacrimejamento e hiperemia conjuntival após 4 e 12 semanas de tratamento. O estudo foi registrado em clinicaltrials.gov com o número de referência NCT01372865. Resultados: A análise de eficácia primária demonstrou não inferioridade do fármaco sob investigação em relação à medicação de controle, visto que o limite superior do intervalo de confiança (IC) de 95% para a diferença entre os percentuais de sucesso após quatro semanas de tratamento (12,6%) situava-se abaixo da margem de não inferioridade proporcionada durante a determinação do tamanho da amostra (13,7%). Eventos adversos foram pouco frequentes e de leve intensidade na maioria dos casos. Conclusão: A eficácia e a segurança de um fármaco experimental no tratamento da rinite alérgica persistente foram similares às do produto de referência, o que demonstrou sua não inferioridade.

RESUMO

Cystic fibrosis (CF) patients with Burkholderia cepacia complex (Bcc) pulmonary infections have high morbidity and mortality. The aim of this study was to compare different methods for identification of Bcc species isolated from paediatric CF patients. Oropharyngeal swabs from children with CF were used to obtain isolates of Bcc samples to evaluate six different tests for strain identification. Conventional (CPT) and automatised (APT) phenotypic tests, polymerase chain reaction (PCR)-recA, restriction fragment length polymorphism-recA, recA sequencing, and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) were applied. Bacterial isolates were also tested for antimicrobial susceptibility. PCR-recA analysis showed that 36 out of the 54 isolates were Bcc. Kappa index data indicated almost perfect agreement between CPT and APT, CPT and PCR-recA, and APT and PCR-recA to identify Bcc, and MALDI-TOF and recA sequencing to identify Bcc species. The recA sequencing data and the MALDI-TOF data agreed in 97.2% of the isolates. Based on recA sequencing, the most common species identified were Burkholderia cenocepacia IIIA (33.4%),Burkholderia vietnamiensis (30.6%), B. cenocepaciaIIIB (27.8%), Burkholderia multivorans (5.5%), and B. cepacia (2.7%). MALDI-TOF proved to be a useful tool for identification of Bcc species obtained from CF patients, although it was not able to identify B. cenocepacia subtypes.

RESUMO

Resumo Objetivo Comparar os resultados obtidos no teste do suor pelo método da condutividade e a dosagem coulométrica de cloreto no suor em recém0nascidos (RN) suspeitos da triagem neonatal para fibrose cística (FC). Métodos O teste do suor foi feito simultaneamente pelos dois métodos em crianças com e sem FC. Os valores de corte para confirmar FC foram na condutividade > 50 mmol/L e no teste coulométrico > 60 mmol/L. Resultados Fizeram o teste do suor por condutividade e dosagem coulométrica simultaneamente 444 RN sem FC (185 do sexo masculino, 234 do feminino e 24 não informado) e obtiveram resultado mediano de 32 mmol/L e 12 mmol/L respectivamente. Para os noventa RN com FC os valores medianos de condutividade e dosagem coulométrica foram 108 mmol/L e 97 mmol/L respectivamente. O índice de falso positivo para condutividade foi de 16,7% e em todos os pacientes FC foi superior a 50 mmol/L, o que confere ao método 100% de sensibilidade (IC 95% = 93,8 a 97,8), especificidade de 96,2% (IC 95% = 93,8 a 97,8), valor preditivo positivo 83,3 (IC 95% = 74,4 a 91,1), valor preditivo negativo 100% (IC 95% = 90,5 a 109,4) e acurácia 9,8%. A correlação entre os métodos foi de r = 0,97 (p > 0,001).O melhor valor de corte sugerido foi de 69,0 mmol/L, coeficiente de kappa = 0,89. Conclusão O teste da condutividade apresentou excelente correlação com o quantitativo coulométrico, alta sensibilidade e especificidade e pode ser usado no diagnóstico da FC em crianças detectadas pela triagem neonatal.


Abstract Objective To compare the results obtained with the sweat test using the conductivity method and coulometric measurement of sweat chloride in newborns (NBs) with suspected cystic fibrosis (CF) in the neonatal screening program. Methods The sweat test was performed simultaneously by both methods in children with and without CF. The cutoff values to confirm CF were >50 mmol/L in the conductivity and >60 mmol/L in the coulometric test. Results There were 444 infants without CF (185 males, 234 females, and 24 unreported) submitted to the sweat test through conductivity and coulometric measurement simultaneously, obtaining median results of 32 mmol/L and 12 mmol/L, respectively. For 90 infants with CF, the median values of conductivity and coulometric measurement were 108 mmol/L and 97 mmol/L, respectively. The false positive rate for conductivity was 16.7%, and was higher than 50 mmol/L in all patients with CF, which gives this method a sensitivity of 100% (95% CI: 93.8-97.8), specificity of 96.2% (95% CI: 93.8-97.8), positive predictive value of 83.3% (95% CI: 74.4-91.1), negative predictive value of 100% (95% CI: 90.5-109.4), and 9.8% accuracy. The correlation between the methods was r = 0.97 (p > 0.001). The best suggested cutoff value was 69.0 mmol/L, with a kappa coefficient = 0.89. Conclusion The conductivity test showed excellent correlation with the quantitative coulometric test, high sensitivity and specificity, and can be used in the diagnosis of CF in children detected through newborn screening.

RESUMO

Hyper-IgM (HIGM) syndrome is a heterogeneous group of disorders characterized by normal or elevated serum IgM levels associated with absent or decreased IgG, IgA and IgE. Here we summarize data from the HIGM syndrome Registry of the Latin American Society for Immunodeficiencies (LASID). Of the 58 patients from 51 families reported to the registry with the clinical phenotype of HIGM syndrome, molecular defects were identified in 37 patients thus far. We retrospectively analyzed the clinical, immunological and molecular data from these 37 patients. CD40 ligand (CD40L) deficiency was found in 35 patients from 25 families and activation-induced cytidine deaminase (AID) deficiency in 2 unrelated patients. Five previously unreported mutations were identified in the CD40L gene (CD40LG). Respiratory tract infections, mainly pneumonia, were the most frequent clinical manifestation. Previously undescribed fungal and opportunistic infections were observed in CD40L-deficient patients but not in the two patients with AID deficiency. These include the first cases of pneumonia caused by Mycoplasma pneumoniae, Serratia marcescens or Aspergillus sp. and diarrhea caused by Microsporidium sp. or Isospora belli. Except for four CD40L-deficient patients who died from complications of presumptive central nervous system infections or sepsis, all patients reported in this study are alive. Four CD40L-deficient patients underwent successful bone marrow transplantation. This report characterizes the clinical and genetic spectrum of HIGM syndrome in Latin America and expands the understanding of the genotype and phenotype of this syndrome in tropical areas.

RESUMO

Objetivo: Determinar a frequência de anticorpos IgE a alérgenos alimentares em pacientes com doenças alérgicas respiratórias por análise molecular. Método: Este estudo transversal incluiu 101participantes, com idades entre 6-18 anos, com diagnóstico de rinite alérgica (89,1% com asmaassociada), sem história de alergia alimentar. Foi realizada análise de IgE sérica específica por ImmunoCAP ISAC, método que emprega biologia molecular para detecção de IgE a componentes alergênicos, sendo 42 alimentares e provenientes das seguintes fontes: abacaxi, aipo, amendoim,avelã, bacalhau, camarão, carpa, castanha de caju, castanha do Pará, cenoura, gergelim, kiwi, leite de vaca, maçã, ovo, pêssego, soja e trigo. Valores ≥ 0,3 ISU (unidades padronizadas do ISAC) foram considerados positivos. Utilizou-se análise estatística descritiva. Resultados: Vinte e sete (26,7%)pacientes apresentaram IgE específica a pelo menos um dos alérgenos alimentares analisados.Entre os 42 componentes alergênicos testados, 20 (47,6%) foram associados a resposta IgE em pelo menos um dos pacientes. Alérgenos com maior frequência de reatividade IgE foram: camarão(Pen a 1 15,8%, Pen i 1 16,8%, Pen m 1 16,8%) e pêssego (Pru p 3 5,9%). Conclusões: Este estudo demonstrou que a avaliação de alergia alimentar baseada em análise molecular deve considerar vários elementos, particularmente a correlação com os sintomas clínicos, e o conhecimento sobre reatividade cruzada IgE entre alérgenos das mais variadas fontes. Presença de IgE específica a determinado componente alergênico significa sensibilização, e não necessariamente alergia.Diagnóstico incorreto de alergia alimentar pode levar a tratamento inadequado, com dietas restritivas desnecessárias e prejuízo nutricional para os pacientes.


Objective: To determine the frequency of IgE antibodies to food allergens in patients with respiratory allergic diseases using molecular analysis. Method: This cross-sectional study included101 participants aged 6-18 years, diagnosed with allergic rhinitis (89.1% with associated asthma),and with no history of food allergy. Analysis of serum specific IgE was carried out using the ImmunoCAP ISAC method, which applies molecular biology tools to the detection of different allergens, including 42 derived from foods (pineapple, celery, peanut, hazelnut, codfish, shrimp,carp, cashew nut, Brazil nut, carrot, sesame, kiwi, cow’s milk, apple, egg, peach, soy, and wheat).Values ≥ 0.3 ISAC standardized units (ISU) were considered to be positive. Descriptive statistical analysis was used. Results: Twenty seven (26.7%) patients presented specific IgE to at leastone of the food allergens analyzed. Among the 42 allergic components tested, 20 (47.6%) were associated with IgE responses in at least one patient. The allergens with the highest frequencies of IgE reactivity were shrimp (Pen a 1 15.8%, Pen i 1 16.8%, Pen m 1 16.8%) and peach (Pru p 3 5.9%).Conclusions: The present study showed that molecular-based evaluation of food allergies should take several elements into consideration, particularly the correlation with clinical symptoms andthe knowledge available on IgE cross-reactivity among allergens from different sources. Presence of specific IgE to one allergen means sensitization, but not necessarily allergy. Misdiagnosis of food allergies may lead to inappropriate treatment, with unnecessarily restrictive diets which could affect the nutritional status of patients.

RESUMO

INTRODUÇÃO: A hiper-responsividade brônquica é a resposta do aumento dos mecanismos fisiológicos protetores das vias aéreas em indivíduos atópicos e não atópicos. Além disso, a magnitude da hiperresponsividade aérea apresenta influência conforme o grau de obesidade. OBJETIVO: Avaliar as respostas fisiológicas em adolescentes obesos submetidos a hiper-responsividade brônquica a solução salina hipertônica. MATERIAIS E MÉTODOS: Estudo descritivo, transversal e correlacional composto por 15 adolescentes obesos, de ambos os gêneros. O diagnóstico de asma foi realizado por meio de histórico clínico e questionário ISAAC, e a obesidade pelo IMC acima do percentil 95. Utilizou-se o teste de broncoprovocação por solução salina hipertônica para avaliação da hiper-responsividade brônquica, considerando positiva uma diminuição do volume expiratório forçado no primeiro segundo (VEF1) > 15% do valor pré-solução salina e a intensidade da hiper-responsividade brônquica foi calculada pela queda percentual máxima do VEF1 (% Queda máxVEF1). Foram utilizados o teste t independente ou U de Mann-Whitney e a correlação de Spearman rho (p < 0,05). RESULTADOS: Não foram encontradas diferenças significativas entre os asmáticos e não asmáticos para as variáveis antropométricas, espirométricas, lipídicas e hemodinâmicas. Verificaram-se moderadas correlações positivas e diferenças significativas entre o % Queda máxVEF1 com o IMC (p = 0,040) e IMC escore-Z (p = 0,028). Foram detectadas correlações negativas e diferenças significativas para a Queda máxVEF1 e leucócitos (p = 0,005) e para o % Queda máxVEF1 com o sulfato de dehidropiandrosterona (p = 0,032). CONCLUSÃO: Pode-se concluir que os adolescentes obesos submetidos a hiper-responsividade brônquica apresentam alterações espirométricas que estão associadas às inflamações sistêmicas da obesidade.


INTRODUCTION: The bronchial hyperresponsiveness is the response of increased physiological protective mechanisms in the airways of atopic and non-atopic individuals. Furthermore, the magnitude of hyperresponsiveness influences provider submits with the degree of obesity. OBJECTIVE: To evaluate the physiological responses in obese adolescents undergoing bronchial hyperresponsiveness to hypertonic saline. MATERIALS AND METHODS: Cross-sectional and correlation study consisted of 15 obese adolescents of both genders. The diagnosis of asthma was made by clinical history and ISAAC, and obesity as BMI above 95th percentile. We used the bronchial provocation test by hypertonic saline for the assessment of bronchial hyperresponsiveness, considering positive a decrease in forced expiratory volume in one second (FEV1) > 15% of pre-saline and the intensity of bronchial hyperresponsiveness was calculated as the percentage fall maximum of FEV1 (% Fall máxFEV1). We used the independent T or Mann-Whitney U test and Spearman's rho correlation (p < 0.05). RESULTS: There were no significant differences between asthmatics and non-asthmatics for anthropometric, spirometric, lipid and hemodynamic variables. There were positive correlations and significant differences between the % Fall máxFEV1 with BMI (p = 0.040) and BMI Z-score (p = 0.028). There were detected negative correlations with significant differences for Fall máxFEV1 and leukocytes (p = 0.005) and the % Fall máxFEV1 with dehydropiandrosterone sulfate (p = 0.032). CONCLUSION: It can be concluded that obese adolescents have bronchial hyperresponsiveness presented spirometric changes that are associated with systemic inflammation of obesity.

RESUMO

The incidence of allergic diseases has increased in recent decades. Therefore, the aim of this systematic review was to assess the efficacy of prebiotics for the prevention and treatment of allergic manifestations in children. We sought to conduct a systematic review of the effectiveness of prebiotics in the prevention and treatment of allergic diseases in children. We searched the MEDLINE, EMBASE, Cochrane Library, LILACS, SciELO, IBECS, Web of Science and Clinical Trials databases as well as Google Scholar and the references of the articles identified. Randomised clinical trials, in which one of the treatments was performed with prebiotics and the control group was treated with placebo, were included in the review. The data selection were performed by two reviewers, and the study quality was evaluated according to the Consolidated Standards of Reporting Trials (CONSORT) items, according to the recommendations for improving the quality of reports of randomised clinical trials. The selected studies showed heterogeneity with regard to the participants, albeit with similar outcomes. The treatment group size ranged from 134 to 259 children, and the studies compared prebiotic to placebo treatment in each group. In general, these articles showed a trend toward less allergic reactions in the groups receiving active therapy with prebiotics. Although there was a trend for reduced allergic symptoms following the administration of prebiotics, there was not sufficient evidence to establish that such treatment is effective for the prevention of allergies in children.

RESUMO

Objetivos: Verificar a reatividade ao teste do soro autólogo em crianças com urticária crônica espontânea e analisar a relação entre o teste do soro autólogo, as características clínicas e o tratamento utilizado nesses pacientes. Método: Este estudo transversal analisou resultados de testes cutâneos com soro autólogo dos pacientes. Foram incluídas crianças com urticária crônica espontânea nos últimos 12 meses, submetidas ao teste do soro autólogo entre agosto/2001 a junho/2012. Soro autólogo (0,05 mL) foi injetado via intradérmica e reações interpretadas após 30 minutos. Medicações que pudessem suprimir a resposta cutânea foram suspensas por 7 dias antes da realização do teste cutâneo. Todos os pacientes foram investigados detalhadamente para urticária crônica e outras doenças. As crianças foram consideradas não responsivas ao tratamento se submetidas ao uso oral de anti-histamínicos em doses habituais, com persistência dos sintomas por no mínimo 3 meses. Resultados: Foram incluídos 57 pacientes (61,4% meninos), com mediana de 10,6 anos (3,7-17,1 anos). Trinta pacientes (53%) apresentaram teste do soro autólogo positivo e 21 destes (70%) não responderam ao tratamento habitual (p < 0,001). Pacientes com teste do soro autólogo positivo apresentaram maior frequência de sintomas, com 1,5 episódios/mês (p = 0,04). Quatorze por cento das crianças apresentaram níveis altos de anticorpo antiperoxidase e 16,6% níveis altos de anticorpo antitireoglobulina. Houve relação significativa entre os altos títulos de anticorpo antiperoxidase com a positividade ao teste do soro autólogo (p = 0,02). Conclusões: A frequência de reatividade ao teste do soro autólogo foialta, sugerindo que o teste deve ser realizado rotineiramente em crianças com urticária crônica espontânea. Pacientes com teste do soro autólogo positivo apresentaram maior chance de não responder ao tratamento habitual.


Objectives: To investigate reactivity to the autologous serum skin test in children with chronic spontaneous urticaria and to analyze the relationship between test results and clinical characteristics and treatment response in these patients. Method: This cross-sectional study analyzed the results of skin tests performed with autologous serum obtained from the patients. Children showing chronic spontaneous urticaria in the past 12 months and subjected to autologous serum skin testing between August 2001 and June 2012 were included. Autologous serum (0.05 mL) was injected intradermally and reactions interpreted after 30 minutes. Medications that could suppress skin response were with held for 7 days prior to skin testing. All patients underwent a thorough workup for chronic urticaria and other illnesses. Children were considered non-responsive if chronic spontaneous urticaria persisted for at least 3 months under regular doses of oral anti-histamines. Results: Fifty seven children were included (61.4% males), with a median age of 10.6 years (3.7-17.1 years). Thirty patients (53%) had positive autologous serum skin tests; of these, 21 (70%) did not respond to treatment (p < 0.001). Patients with a positive autologous serum skin test showed.

RESUMO

CD40 ligand (CD40L) deficiency or X-linked hyper-IgM syndrome (X-HIGM) is a well-described primary immunodeficiency in which Pneumocystis jiroveci pneumonia is a common clinical feature. We have identified an unusual high incidence of fungal infections and other not yet described infections in a cohort of 11 X-HIGM patients from nine unrelated Brazilian families. Among these, we describe the first case of paracoccidioidomycosis (PCM) in X-HIGM. The molecular genetic analysis of CD40L was performed by gene sequencing and evaluation of CD40L protein expression. Nine of these 11 patients (82%) had fungal infections. These included fungal species common to CD40L deficiency (P. jiroveci and Candida albicans) as well as Paracoccidioides brasiliensis. One patient presented with PCM at age 11 years and is now doing well at 18 years of age. Additionally, one patient presented with a simultaneous infection with Klebsiella and Acinetobacter, and one with condyloma caused by human papilloma virus. Molecular analysis revealed four previously described CD40L mutations, two novel missense mutations (c.433 T > G and c.476 G > C) resulting in the absence of CD40L protein expression by activated CD4(+) cells and one novel insertion (c.484_485insAA) within the TNFH domain leading to a frame shift and premature stop codon. These observations demonstrated that the susceptibility to fungal infections in X-HIGM extends beyond those typically associated with X-HIGM (P. jiroveci and C. albicans) and that these patients need to be monitored for those pathogens.

RESUMO

BACKGROUND: Patients with X-linked hyper-IgM syndrome (X-HIGM) due to CD40 ligand (CD40L) mutations are susceptible to fungal pathogens; however, the underlying susceptibility mechanisms remain poorly understood. OBJECTIVE: To determine whether monocyte-derived dendritic cells (DCs) from patients with X-HIGM exhibit normal responses to fungal pathogens. METHODS: DCs from patients and controls were evaluated for the expression of costimulatory (CD80 and CD86) and MHC class II molecules and for their ability to produce IL-12 and IL-10 in response to Candida albicans and Paracoccidioides brasiliensis. We also evaluated the ability of C albicans- and P brasiliensis-pulsed mature DCs to induce autologous T-cell proliferation, generation of T helper (T(H)) 17 cells, and production of IFN-γ, TGF-ß, IL-4, IL-5, and IL-17. RESULTS: Immature DCs from patients with X-HIGM showed reduced expression of CD80, CD86, and HLA-DR, which could be reversed by exogenous trimeric soluble CD40L. Most important, mature DCs from patients with X-HIGM differentiated by coculturing DCs with fungi secreted minimal amounts of IL-12 but substantial amounts of IL-10 compared with mature DCs from normal individuals. Coculture of mature DCs from X-HIGM patients with autologous T cells led to low IFN-γ production, whereas IL-4 and IL-5 production was increased. T-cell proliferation and IL-17 secretion were normal. Finally, in vitro incubation with soluble CD40L reversed the decreased IL-12 production and the skewed T(H)2 pattern response. CONCLUSION: Absence of CD40L during monocyte/DC differentiation leads to functional DC abnormalities, which may contribute to the susceptibility to fungal infections in patients with X-HIGM.

RESUMO

OBJETIVO: Comparar a função pulmonar de indivíduos obesos mórbidos submetidos à gastroplastia. MÉTODOS: Participaram da pesquisa 25 indivíduos, divididos em grupo experimental com 15 sujeitos (feminino = 13 e masculino = 2) e grupo controle com 10 sujeitos (feminino = 8 e masculino = 2). Foram mensurados os valores espirométricos na fase pré-operatória e na fase pós-operatória, três meses após a cirurgia. RESULTADOS: Verificou-se diferença significante intragrupo na análise inicial e após os três meses de acompanhamento de peso, índice de massa corporal (IMC), Capacidade Vital forçada (CVF), Volume de Reserva Expiratório (VRE), Capacidade Inspiratória (CI) e do Fluxo Expiratório Forçado (FEF25-75 por cento), nos indivíduos que foram submetidos à cirurgia. Para os resultados obtidos da análise de diferença entre os grupos experimental e controle na análise de grupo e tempo, foram considerados significativos a CVF e o VRE. Verificou-se que aqueles que apresentavam distúrbios inespecíficos na fase pré-operatória passaram a ter função pulmonar normal na fase pós-operatória. Não foram verificadas diferenças significativas entre as características de proporções da espirometria entre os grupos e na avaliação intragrupo experimental. CONCLUSÃO: A cirurgia bariátrica influencia na melhora da função pulmonar, observando que um tempo maior de acompanhamento desses indivíduos pode nos mostrar resultados ainda mais confirmatórios sobre a importância da perda de peso para a função pulmonar.


OBJECTIVE: To compare the pulmonary function of individuals morbidly obese submitted to gastroplasty. METHODS: 25 individuals participated of this research, divided in experimental group with 15 subjects (female = 13 and male = 2) and control group with10 subjects (female = 8 and male = 2). Spirometric values were measured in the pre-operative and post-operative phase, three months after surgery. RESULTS: There was a significant difference intragroup in the initial analysis after three months follow-up weight, body mass index (BMI), Forced Vital Capacity (FVC), Expiratory Reserve Volume (ERV), Inspiratory Capacity (IC) and the Forced Expiratory Flow (FEF25-75 percent), in individuals who underwent surgery. For the results of the analysis of the differences between the experimental and control groups in the analysis of group and time, it were considered significant FVC and ERV. Verified that those nonspecific disturbances in the pre-operative and began to have normal lung function in the post-operative phase. There were not significant differences between the characteristics of the proportions of spirometry between groups and the intragroup experimental evaluation. CONCLUSION: Bariatric surgery influences in relation to improvement in lung function, observing that a longer follow-up of these individuals can show results in further confirming the importance of weight loss for lung function.

RESUMO

OBJECTIVE: To use clinical and spirometry findings in order to distinguish between the restrictive and nonspecific patterns of pulmonary function test results in patients with low FVC and a normal or elevated FEV1/FVC ratio. METHODS: We analyzed the pulmonary function test results of 211 adult patients submitted to spirometry and lung volume measurements. We used the clinical diagnosis at the time spirometry was ordered, together with various functional data, in order to distinguish between patients presenting with a "true" restrictive pattern (reduced TLC) and those presenting with a nonspecific pattern (normal TLC). RESULTS: In the study sample, TLC was reduced in 144 cases and was within the normal range in 67. The most common causes of a nonspecific pattern were obstructive disorders, congestive heart failure, obesity, bronchiolitis, interstitial diseases, and neuromuscular disorders. In patients given a working diagnosis of pulmonary fibrosis, pleural disease, or chest wall disease, the positive predictive value (PPV) for restriction was >or= 90%. In males, an FVC or= 0% between the FEV1% and the FVC% had a PPV for restriction of 89.5%. After performing logistic regression, we developed a point scale for predicting the restrictive pattern. CONCLUSIONS: In many patients with reduced FEV1, reduced FVC, and a normal FEV1/FVC ratio, the restrictive pattern can be identified with confidence through the use of an algorithm that takes the clinical diagnosis and certain spirometry measurements into account.

RESUMO

OBJETIVO: Utilizar os dados clínicos e espirométricos para distinguir entre os padrões restritivo e inespecífico dos resultados dos testes de função pulmonar em pacientes com CVF reduzida e relação VEF1/CVF normal ou elevada. MÉTODOS: Foram avaliados resultados de testes de função pulmonar de 211 pacientes adultos submetidos à espirometria e a medidas de volumes pulmonares. O diagnóstico clínico na solicitação do exame e diversos dados funcionais foram utilizados para diferenciar pacientes com o padrão restritivo "verdadeiro" (CPT reduzida) daqueles com o padrão inespecífico (CPT normal). RESULTADOS: Na amostra estudada, a CPT estava reduzida em 144 casos e estava dentro da faixa normal em 67. As causas mais comuns do padrão inespecífico foram doenças pulmonares obstrutivas, insuficiência cardíaca congestiva, obesidade, bronquiolite, doenças intersticiais e doenças neuromusculares. Em pacientes com hipótese diagnóstica de fibrose pulmonar, doenças pleurais ou doenças da parede torácica, o valor preditivo positivo (VPP) para restrição foi > 90 por cento. Em homens, a CVF < 60 por cento do previsto teve um VPP para restrição de 98,8 por cento. Em mulheres, o padrão restritivo foi encontrado em 84,4 por cento daquelas com CVF < 50 por cento do previsto. Uma diferença entre VEF1 por cento e CVF por cento > 0 por cento teve um VPP para restrição de 89,5 por cento. Após regressão logística, uma escala de pontos foi desenvolvida para predizer o padrão restritivo. CONCLUSÕES: O padrão restritivo pode ser identificado com segurança em diversos casos com VEF1 e CVF reduzidos e relação VEF1/CVF normal usando-se um algoritmo que leva em conta o diagnóstico clínico e alguns achados espirométricos.
