- Microbiological profile in chronic granutomatous disease patients in a single Brazilian primary immunodeficiencies center(2021) OLIVEIRA, Aimee Filippini Bifulco; PASTORINO, Antonio Carlos; DORNA, Mayra de Barros; CASTRO, Ana Paula Beltran Moschione; PEGLER, Jose Roberto Mendes; MORGENSTERN, Beni; CARNEIRO-SAMPAIO, Magda Maria SalesBackground: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency. Infections of the lungs, skin, lymph nodes, and liver are the hallmark of CGD with frequent initial manifestations of the disease. The aim of the present study was to describe the sites of infections and their causative agents in 38 CGD pediatric patients. Methods: This was a retrospective single-center cohort study comprising CGD patients, and followed for over last 40 years at the Allergy and Immunology Unit of a tertiary hospital in Sao Paulo, Brazil. Sites of infections and their causative agents were described. Results: A total of 38 patients were included (36 males and 2 females). Median age at the onset of symptoms was 45 days (7 days-7 years) and that at the time of diagnosis was 23 months (1 month-12 years); 31.6% of the parents reported death of relatives during childhood and 21% (8 cases) had another mate family member with CDG. The most common infections were pneumonia (81.6%), skin infections (50.0%), adenitis (42.1%), and liver abscess (23.7%). In all, 188 cultures were positive (85.6% for bacteria and 14.4% for fungi). The most prevalent bacterial agents were Staphylococcus sp. (12.4%), Staphylococcus aureus (11.2%), and Klebsiella pneumoniae (9.3%). Aspergillus sp. and Candida sp. were 56% and 22.2% of the isolated fungi, respectively. Mycobacterium tuberculosis was isolated in 5.6% and Mycobacterium bovis in 0.9% (only in 1 patient) of cultures. Conclusion: Staphylococcus sp., Staphylococcus aureus, and Aspergillus sp. were the most frequent agents in this cohort. M. tuberculosis should be considered in endemic areas. Detection of infectious agents drives to find adequate treatment and benefits the evolution of patients with CGD. (C) 2021 Codon Publications.
- Cytogenomics Investigation of Infants with Congenital Heart Disease: Experience of a Brazilian Center(2022) GRASSI, Marcilia Sierro; MONTENEGRO, Marilia; ZANARDO, Evelin Aline; PASTORINO, Antonio Carlos; DORNA, Mayra Barros; KIM, Chong; JATENE, Marcelo; MIURA, Nana; KULIKOWSKI, Leslie; CARNEIRO-SAMPAIO, MagdaBackground: Some syndromes have specific and easily recognizable features, while others may be more complex to identify and may present different phenotypic manifestations, for example. An etiological diagnosis is important to understand the nature of the disease, to establish the prognosis and to start the treatment, allowing the inclusion of patients in society and reducing the financial cost of such diseases. Objective: The initial proposal of this study was cytogenetic screening for the detection of the 22q11.2 deletion syndrome in consecutive newborns and infants with congenital heart disease using the multiplex ligation-dependent probe amplification (MLPA) technique. Therefore, throughout our research, other genomic alterations were identified in these cardiac patients. Thus, our objective was extended to investigate these other cytogenetic alterations. Methods: We investigated 118 neonates with congenital heart diseases born consecutively during one year using the MLPA technique. Results: The MLPA technique allowed the detection of 22q11.2DS in 10/118 patients (8.5%). Other genomic alterations were also identified in 6/118 patients (5%): 1p36 del, 8p23 del (2 cases), 7q dup, 12 dup and 8q24 dup. Conclusion: This study highlights the relevance of detecting genomic alterations that are present in newborns and infants with congenital cardiac diseases using cytogenomic tools.
- Common Variable Immunodeficiency Associated with Hepatosplenic T-Cell Lymphoma Mimicking Juvenile Systemic Lupus Erythematosus(2011) JESUS, A. A.; JACOB, C. M. A.; SILVA, C. A.; DORNA, M.; PASTORINO, A. C.; CARNEIRO-SAMPAIO, M.Common variable immunodeficiency (CVID) is a heterogeneous disorder with susceptibility to infections, autoimmune manifestations, and cancer. To our knowledge, CIVD with T-cell lymphoma mimicking juvenile systemic lupus erythematosus (JSLE) was not described in the literature, and one case was reported herein. An 8-year-old female was admitted in our Pediatric Immunology Unit with a clinical history of hypogammaglobulinemia, recurrent upper respiratory infections, and pneumonias. She had a marked decrease of three serum immunoglobulin isotypes, and the diagnosis of CVID was established. At the age of 17 years, she presented with oral ulceration, nonerosive arthritis, nephritis, serositis, cytopenia, positive antiphospholipid antibodies, and positive antinuclear antibody fulfilling the American College of Rheumatology (ACR) criteria for SLE. She was treated with intravenous methylprednisolone for three consecutive days, and intravenous immunoglobulin, and maintenance therapy of chloroquine, azathioprine and prednisone 40mg/day. Two months later, she died of septic shock secondary to acute pneumonia. The necropsy showed hepatosplenic T-cell lymphoma with diffuse involvement of bone marrow, spleen, liver, and lungs. The lymphoma cells were positive for CD3 immunostaining and negative for CD20 and lysozyme. In conclusion, the association of CVID and hepatosplenic T-cell lymphoma may simulate JSLE diagnosis.
- Laboratory screening test with inhalant and food allergens in atopic Brazilian children and adolescents: a performance(2021) REALI, Ana Carolina Rozalem; PIEROTTI, Felipe Faria; ARANDA, Carolina Sanchez; COCCO, Renata Rodrigues; SARINHO, Emanuel S. Cavalcanti; SANO, Flavio; PORTO NETO, Arnaldo; ROSARIO, Nelson A.; CHONG NETO, Herberto J.; GOUDOURIS, Ekaterini Simoes; MORAES, Lilian Sanches; WANDALSEN, Neusa Falbo; PASTORINO, Antonio Carlos; FRANCO, Jackeline Motta; CHAVARRIA, Maria Leticia; BORRES, Magnus P.; SOLE, DirceuThe Phadiatop Infant (R)) is a panel developed to assess allergic sensitization (immunoglobulin E [IgE]) in children aged <5 years and combines inhalant and food allergens. The test has not been evaluated outside Europe. This is a cross-sectional study conducted at 11 pediatric allergy centers to evaluate PhInf as an allergic disease screening method in Brazilian children. Children as controls and patients (aged 6 months-18 years) were grouped according to their primary disease and age group. PhInf and specific serum IgE (sIgE) screening was performed for Dermatophagoides pteronyssinus (DP), cat and dog epithelia, a mix of grasses and pollens, eggs, cow's milk, peanuts, and shrimp. Values >= 0.35 kU (A)/L (or PAU/L) were considered positive. A total of 470 children and adolescents, which included 385 patients and 85 controls, participated in the study (47.7% boys, average age: 6.3 years). In all, 72.6% of the participants had positive PhInf test (n = 341), with a higher proportion of those having food allergy (92.6%), atopic dermatitis (91.9%), and those aged >13 years having allergy (95%). The PhInf and sIgE agreement between patients (Kappa = 0.94, P < 0.001) and controls (Kappa = 0.84, P < 0.001) was high. PhInf and DP agreement in patients aged >13 years was excellent (Kappa = 0.936, P < 0.001). Compared with sIgE dosage, PhInf had high sensitivity (97%) and specificity (93%). Positivity of PhInf test in this population was high and had an excellent correlation with the allergens comprising the panel. It is a useful method for screening children suspected of having allergic diseases in a non-European country. (C) 2021 Codon Publications.
- Idiopathic musculoskeletal pain, musculoskeletal pain syndromes, and use of electronic devices in adolescents with asthma(2022) NASTRI, Mariana Machado Forti; LOURENCO, Benito; QUEIROZ, Ligia Bruni; SILVA, Luiz Eduardo Vargas da; LOURENCO, Daniela Mencaroni Rodrigues; CASTRO, Ana Paula Beltran Moschione; SILVA, Clovis Artur; PASTORINO, Antonio CarlosObjective: To evaluate idiopathic musculoskeletal pain, musculoskeletal pain syndromes, and use of electronic devices in adolescents with asthma and healthy controls. Methods: Cross-sectional study was conducted on 150 asthmatic adolescents and 300 controls. Adolescents completed a self-administered questionnaire regarding painful symptoms, use of electronic devices, and physical activity. Seven musculoskeletal pain syndromes were evaluated, and Asthma Control Test (ACT) was assessed. Results: Musculoskeletal pain (42% vs. 61%, p = 0.0002) and musculoskeletal pain syndromes (2.7% vs. 15.7%, p = 0.0006) were significantly lower in asthmatic adolescents than in controls. The frequency of pain in the hands and wrists was reduced in asthmatic than in controls (12.6% vs. 31.1%, p = 0.004), in addition to cell phone use (80% vs. 93%, p < 0.0001), simultaneous use of at least two electronic media (47% vs. 91%, p < 0.0001), myofascial syndrome (0% vs. 7.1%, p = 0.043), and tendinitis (0% vs. 9.2%, p = 0.008). Logistic regression analysis, including asthma with musculoskeletal pain as the dependent variable, and female sex, ACT > 20, simultaneous use of at least two electronic devices, cell phone use, and weekends and weekdays of cell phone use, as independent variables, showed that female sex (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.929-6.316; p = 0.0009) and ACT >= 20 (OR, 0.194; 95% CI, 0.039-0.967; p = 0.045) were associated with asthma and musculoskeletal pain (Nagelkerke R-2 = 0.206). Conclusions: Musculoskeletal pain and musculoskeletal pain syndromes were lower in adolescents with asthma. Female sex was associated with musculoskeletal pain in asthmatic, whereas patients with asthma symptoms and well-controlled disease reported a lower prevalence of musculoskeletal pain.

- Hematopoietic Stem Cell Transplantation for Chronic Granulomatous Disease in a Single Institution in Brazil. Reproducing Good Results with a Reduced Toxicity Regimen(2017) FERNANDES, Juliana Folloni; MANTOVANI, Luiz Fernando Alves Lima; VENANCIO, Angela Mandelli; DORNA, Mayra; PASTORINO, Antonio Carlos; VASCONCELOS, Dewton; NETO, Antonio Condino; MOURA, Ana Carla Augusto; COLLASSANTI, Maria Dulce; ZANICHELLI, Maria Aparecida; CARNEIRO-SAMPAIO, Magda; ROCHA, Vanderson G.; ODONE FILHO, Vicente
- Allergic sensitization pattern of patients in Brazil(2021) ARANDA, Carolina Sanchez; COCCO, Renata R.; PIEROTTI, Felipe F.; SARINHO, Emanuel; SANO, Flavio; PORTO, Arnaldo; ROSARIO, Nelson; CHONG NETO, Herberto J.; GOUDOURIS, Ekaterini; MORAES, Lillian S.; WANDALSEN, Neusa F.; MALLOZI, Marcia C.; PASTORINO, Antonio C.; FRANCO, Jackeline M.; CHAVARRIA, Maria L.; BORRES, Magnus; SOLE, DirceuObjective: Allergic sensitization is one of the key components for the development of allergies. Polysensitization seems to be related to the persistence and severity of allergic diseases. Furthermore, allergic sensitization has a predictive role in the development of allergies. The aim of this study was to characterize the pattern of sensitization of atopic patients treated at different pediatric allergy referral centers in Brazil. Methods: A nation-wide transversal multicenter study collected data on patients attended in Brazil. Peripheral blood samples were collected to determine the serum levels of allergen-specific IgE. If allergen-specific IgE was higher than 0.1 kUA/L, the following specific components were quantified. Results: A total of 470 individuals were enrolled in the study. Mite sensitization was the most frequent kind in all participants. A high frequency of sensitization to furry animals and grasses featured in the respiratory allergies. Regarding components, there was a predominance of sensitization to Der p 1 and Der p 2. It has been verified that having a food allergy, atopic dermatitis, or multimorbidity are risk factors for the development of more severe allergic disease. Conclusion: Studies on the pattern of allergic sensitization to a specific population offer tools for the more effectual prevention, diagnosis, and treatment of allergic diseases. Sensitization to dust mites house was the most prevalent in the evaluated sample. High rates of sensitization to furry animals also stand out. Patients with food allergy, atopic dermatitis, or multimorbidity appear to be at greater risk for developing more severe allergic diseases. (C) 2020 Sociedade Brasileira de Pediatria.
- Cow's milk allergy: Evaluating tolerance through skin-prick test(2016) NEVES, Flavia Valenca De Oliveira; BECK, Cleonir De Moraes Lui; GUSHKEN, Andrea Keiko Fujinami; YONAMINE, Glauce Hiromi; CASTRO, Ana Paula Beltran Moschione; DORNA, Mayra De Barros; SANTOS, Cristiane De Jesus Nunes Dos; PASTORINO, Antonio CarlosObjective: To evaluate the wheal diameter in allergy skin-prick tests (SPT) with cow's milk extract (CM) comparing tolerant and persistent patients. Method: A retrospective cohort study involving database analysis of children with diagnosis of cow's milk protein allergy (CMPA) mediated by immunoglobulin E in a specialized outpatient clinic that regularly performed SPT between January 2000 and July 2015. Patients were allocated into two groups: tolerant or persistent. Comparisons were made at diagnosis and over time between tolerant and persistent patients using Fisher's, Mann-Whitney or Wilcoxon tests and significance level at 5%. Results: After applying inclusion and exclusion criteria, the sample includes 44 patients (29 tolerant and 15 who persisted with CMPA). In the tolerant group, the medians of SPT were: 6 mm at diagnosis and 2 mm at the development of tolerance; a significant difference (p<0.0001) was found. In the persistent group, the median SPT at diagnosis was 7 mm, while in the last SPT it was 5 mm, with no statistical difference (p=0.173). The comparison of medians in the last SPT between groups was significant (p=0.001), with a reduction greater than 50% in SPT in the tolerant group. Conclusion: Serial SPTs were useful for diagnosis, and a decrease higher than 50% in diameter can indicate the moment to perform oral food challenge (OFC) tests, helping to detect tolerance in CMPA.
- Cardiopatias Congênitas como um Sinal de Alerta para o Diagnóstico da Deleção do 22q11.2(2014) GRASSI, Marcilia S.; JACOB, Cristina M. A.; KULIKOWSKI, Leslie D.; PASTORINO, Antonio C.; DUTRA, Roberta L.; MIURA, Nana; JATENE, Marcelo B.; PEGLER, Stephanie P.; KIM, Chong A.; CARNEIRO-SAMPAIO, MagdaBackground: To alert for the diagnosis of the 22q11.2 deletion syndrome (22q11.2DS) in patients with congenital heart disease (CHD). Objective: To describe the main CHDs, as well as phenotypic, metabolic and immunological findings in a series of 60 patients diagnosed with 22q11.2DS. Methods: The study included 60 patients with 22q11.2DS evaluated between 2007 and 2013 (M: F = 1.3, age range 14 days to 20 years and 3 months) at a pediatric reference center for primary immunodeficiencies. The diagnosis was established by detection of the 22q11.2 microdeletion using FISH (n = 18) and/or MLPA (n = 42), in association with clinical and laboratory information. Associated CHDs, progression of phenotypic facial features, hypocalcemia and immunological changes were analyzed. Results: CHDs were detected in 77% of the patients and the most frequent type was tetralogy of Fallot (38.3%). Surgical correction of CHD was performed in 34 patients. Craniofacial dysmorphisms were detected in 41 patients: elongated face (60%) and/or elongated nose (53.3%), narrow palpebral fissure (50%), dysplastic, overfolded ears (48.3%), thin lips (41.6%), elongated fingers (38.3%) and short stature (36.6%). Hypocalcemia was detected in 64.2% and decreased parathyroid hormone (PTH) level in 25.9%. Decrease in total lymphocytes, CD4 and CD8 counts were present in 40%, 53.3% and 33.3%, respectively. Hypogammaglobulinemia was detected in one patient and decreased concentrations of immunoglobulin M (IgM) in two other patients. Conclusion: Suspicion for 22q11.2DS should be raised in all patients with CHD associated with hypocalcemia and/or facial dysmorphisms, considering that many of these changes may evolve with age. The 22q11.2 microdeletion should be confirmed by molecular testing in all patients.
- Interleukin 10 (IL10) and transforming growth factor beta 1 (TGF beta 1) gene polymorphisms in persistent IgE-mediated cow's milk allergy(2013) JACOB, Cristina Miuki Abe; PASTORINO, Antonio Carlos; OKAY, Thelma Suely; CASTRO, Ana Paula B. M.; GUSHKEN, Andrea Keiko F.; WATANABE, Leticia Aki; FRUCCHI, Vanessa C. Z.; OLIVEIRA, Lea Campos deOBJECTIVES: The aim of this cross-sectional study was to evaluate whether interleukin 10 (IL10) and transforming growth factor beta 1 (TGF beta 1) gene polymorphisms were associated with persistent IgE-mediated cow's milk allergy in 50 Brazilian children. The diagnostic criteria were anaphylaxis triggered by cow's milk or a positive double-blind, placebo-controlled food challenge. Tolerance was defined as the absence of a clinical response to a double-blind, placebo-controlled food challenge or cow's milk exposure. METHOD: The genomic DNA of the 50 patients and 224 healthy controls (HCs) was used to investigate five IL10 gene polymorphisms (-3575A/T, -2849A/G, -2763A/C, -1082G/A, -592C/A) and one TGF beta 1 polymorphism (-509C/T). RESULTS: Among the five IL10 polymorphisms analyzed, homozygosis for the G allele at the -1082 position was significantly higher in the patients compared with the healthy controls (p = 0.027) and in the persistent cow's milk allergy group compared with the healthy controls (p = 0.001). CONCLUSIONS: Homozygosis for the G allele at the IL10 -1082G/A polymorphism is associated with the persistent form of cow's milk allergy.
