- 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.

conferenceObject Pulmonary Morphologic and Functional Abnormalities in Patients with Primary Hypogammaglobulinemia(2012) DORNA, Mayra de Barros; CASTRO, Ana Paula B. Moschione; PASTORINO, Antonio Carlos; CARNEIRO-SAMPAIO, Magda M. Sales; JACOB, Cristina Miuki AbeRetrospective evaluation of 30 patients (21 M) aged 4.6–23.4 y (median 16.7 y) with predominantly humoral PID(9IDCV;14XLA;7HIGM).Mediantimeof follow-up9.2y(1.8–17.5). Median age of symptoms’ onset8mo(1–96 mo), age at diagnosis 5.8 y (7–175 mo) and diagnostic delay 4.7 y (0.2–13 y). Pneumonia was the main manifestation before diagnosis (24/30 patients) with frequency of 0.6/patient/year. After beginning IVIG, frequency of pneumonias decreased to 0.1 (p<0.001) and the frequency of sinusitis increased from0to0.55(p<0.001). Higher age at diagnosis and longer diagnostic delay were associated to bronchiectasis at diagnosis (p=0.016 and p<0.001). Seven patients developed bronchiectasis during follow-up. Spirometry (23/30 patients), 1–15 y after IVIG was abnormal in 13 (9 obstructive; 4 restrictive). Humoral PID often affects respiratory tract and IVIG reduces complications but pulmonary monitoring is essential to guarantee adequate therapeutic interventions.conferenceObject Familial Hemophagocytic Lymphohistiocytosis Caused by Perforin Deficiency in Brazilian Twins(2012) JACOB, Cristina Miuki Abe; SANTOS, Cristiane de Jesus Nunes dos; SAINT-BASILE, Genevieve de; CASTRO, Ana Paula B. Moschione; PASTORINO, Antonio Carlos; FERNANDES, Juliana Folloni; ROCHA, Vanderson; CARNEIRO-SAMPAIO, Magda M. SalesTwo female monozygotic twins presented: Case1-at2mo presented fever and vomiting after vaccination with DTP, Haemophilus, Salk, Rotavirus. The initial evaluation showed: anemia, hepatosplenomegaly, pancytopenia, LDH=0760 U/L, ferritin=0622 ng/mL and triglycerides=0362 mg/dL. Hemophagocytosis was found in bone marrow. Case2: clinically asymptomatic, being detected anemia, LDH=0726 U/L, ferritin=0436 ng/mL, triglycerides=0166 mg/dL, without hemophagocytosis. Infections were excluded in both. Molecular testing identified two heterozygous mutations in the perforin gene, C46T leading to P16S and 50delT leading to L17 stop, making the diagnosis of FHL type 2. Both twins underwent to therapy based on HLH-2004 protocol followed by cord blood transplantation and after CMV infection with a good response to treatment. FHL should be suspected in all children with fever, visceromegaly and cytopenias for early treatment, including hematopoietic stem cell transplantation.conferenceObject Inflammatory Manifestations in Children with Chronic Granulomatous Disease(2020) TATEBE, Myris Satiko Shinzato; DORNA, Mayra De Barros; CASTRO, Ana Paula Beltran Moschione; PASTORINO, Antonio Carlos; CARNEIRO-SAMPAIO, MagdaconferenceObject Yellow Fever: Is It Possible to Vaccinate Patients with IgA Deficiency?(2019) CARNEIRO-SAMPAIO, Magda; CASTIGLIONI, Mariana; SOUZA, Nathalia; AQUILANTE, Bruna; DORNA, Mayra; CASTRO, Ana Paula; PASTORINO, Antonio CarlosconferenceObject Chediak-Higashi Syndrome: Experience from a Brazilian Reference Center For Primary Immunodeficiencies(2014) CUNHA, Patricia Salles; PINHO, Liliana; PASTORINO, Antonio Carlos; CASTRO, Ana Paula B.
