    (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 Sales
    Background: 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, Magda
    Background: 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.

    Retrospective 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.

    SERIOUS OPHTHALMOLOGIC COMPLICATIONS OF PRIMARY IMMUNODEFICIENCY PATIENTS
    (2012) ALVAREZ, H. T.; SUZUKI, A. C. F.; TAKIUTI, J. H.; FERRIANI, M. P.; DORNA, M.; SANTOS, C.; PASTORINO, A. C.; CASTRO, A. P. B.; CARNEIRO-SAMPAIO, M.; JACOB, C. M.
    Introduction: Primary immunodeficiencies (PID) are genetic diseases characterized by high susceptibility to infections. Although the manifestations affect all organs, there are few reports about ocular complications. Objective: To describe four patients with serious ophthalmologic complications in Brazilian patients followed at a reference center for PID. Methods: It was a retrospective study including patients with ocular serious complains. Medical records of 4 PID patients were evaluated for clinical data and the PID diagnosis was based on the PAGID/ ESID criteria. These patients underwent to ophthalmologic evaluation, including visual acuity, biomicroscopy and fundus examination. Ophthalmologic evaluation was done routinely only for AT and CHS diagnosis. Results: The PIDs patients included were: HLH, GCD, CMC and A-T. The HLH patient had a heterozygous mutation at the perforin gene (FHL type 2), CMC patient had a heterozygous mutation at STAT1. Ocular complains were: ocular pain, hyperemia, eyelids edema and strabismus and the characteristics of each patient were: - Female, 13y, CMC- conjunctivitis and eyelids edema with infraorbital infected papules. - Female, 6 mo, HLH- acute strabismus in consequence of neurological involvement by HLH. - Male, 15y, AT- herpes conjunctivitis and loss of vision in left eye. - Male, 9y CGD - Conjunctivitis in the left eye, progressing to edema and proptosis. The diagnosis was endophthalmitis granulomatous with loss of vision in left eye. Conclusion: Although not common in PID patients, the ocular complications may lead to loss of vision. The ophthalmologic evaluation would be routinely recommended for all PID patients to avoid important sequels.

    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. Sales
    Two 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.

    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, Magda
    Background: 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.
