RESUMO
BACKGROUND: The CDC and ACIP recommend COVID-19 vaccination for patients with inborn errors of immunity (IEI). Not much is known about vaccine safety in IEI, and whether vaccination attenuates infection severity in IEI. OBJECTIVE: To estimate COVID-19 vaccination safety and examine effect on outcomes in patients with IEI. METHODS: We built a secure registry database in conjunction with the US Immunodeficiency Network to examine vaccination frequency and indicators of safety and effectiveness in IEI patients. The registry opened on January 1, 2022, and closed on August 19, 2022. RESULTS: Physicians entered data on 1245 patients from 24 countries. The most common diagnoses were antibody deficiencies (63.7%). At least one COVID-19 vaccine was administered to 806 patients (64.7%), and 216 patients received vaccination prior to the development of COVID-19. The most common vaccines administered were mRNA-based (84.0%). Seventeen patients were reported to seek outpatient clinic or emergency room care for a vaccine-related complication, and one patient was hospitalized for symptomatic anemia. Eight hundred twenty-three patients (66.1%) experienced COVID-19 infection. Of these, 156 patients required hospitalization (19.0%), 47 required ICU care (5.7%), and 28 died (3.4%). Rates of hospitalization (9.3% versus 24.4%, p < 0.001), ICU admission (2.8% versus 7.6%, p = 0.013), and death (2.3% versus 4.3%, p = 0.202) in patients who had COVID-19 were lower in patients who received vaccination prior to infection. In adjusted logistic regression analysis, not having at least one COVID-19 vaccine significantly increased the odds of hospitalization and ICU admission. CONCLUSION: Vaccination for COVID-19 in the IEI population appears safe and attenuates COVID-19 severity.

Los errores innatos de la inmunidad (EII), antes llamados inmunodeficiencias primarias (IDP), son un grupo heterogéneo de trastornos genéticos con defectos en uno o más componentes del sistema inmune. Los pacientes afectados por EII presentan aumentada susceptibilidad a microorganismos únicos o múltiples que se manifestará con infecciones recurrentes de diferente tipo y gravedad dependiendo del tipo de la localización del defecto. La prevención de infecciones es uno de los pilares fundamentales en el abordaje integral de los pacientes con EII. En este trabajo se resumen las conclusiones consensuadas en el Grupo de Trabajo de Inmunología Pediátrica de la Sociedad Argentina de Pediatría, sobre la base de la revisión de la evidencia disponible, respecto a los principios esenciales para el cuidado, la prevención de infecciones y la quimioprofilaxis en los errores innatos de la inmunidad para la orientación del pediatra y especialista dedicados al seguimiento de estas enfermedades.
Inborn errors of immunity, previously named primary immunodeficiency are a heterogeneous group of genetic defects of different components of the immune system. Patients present high susceptibility to an only or several microorganisms, developing recurrent infections; the severity is related to the specific genetic type of immunity defect. The main strategy on the management of these illness is the prevention of infections. These consensus guidelines made by the Pediatric Immunology Work Group of Sociedad Argentina de Pediatría, givese main approaches of infection prevention in order to provide a useful tool for all practitioners who are involved in the management of these patients, based on scientific evidence and broad consensus of a specialized panel expert.

La dermatitis atópica es la forma más frecuente de eccema durante el primer año de vida; sin embargo, cuando la presentación es atípica o se asocia a infecciones, constituye un desafío diagnóstico para el pediatra. Es importante mantener un índice alto de sospecha para detectar inmunodeficiencias primarias asociadas a eccemas graves desde el período neonatal. Un ejemplo de estas es el síndrome de hiperinmunoglobulinemia E (hiper-IgE) autosómico dominante. Este cuadro se caracteriza por la presencia de infecciones cutáneas y respiratorias recurrentes, dermatitis atópica, eosinofilia y aumento de IgE. Se reporta el caso clínico de una niña de 1 mes y 29 días con diagnóstico de hiper-IgE con afección cutánea desde el nacimiento.
Atopic dermatitis is the most common form of eczema often developed before the first year of life. Nevertheless, when the presentation is atypical or related to infections the diagnostic represents a challenge for the pediatricians. It is important to maintain a high index of suspicion for the detection of primary immunodeficiency associated to severe eczema. One of them is the autosomal dominant hyper-IgE syndrome characterized by recurrent skin and respiratory infections, atopic dermatitis, eosinophilia, and high serum IgE concentrations. In this paper, we report a 1 months and 29 days old baby girl diagnosed with hyper-IgE and a skin involvement since birth.

Due to the high burden of disease associated with rotavirus, the massive vaccination in children before six months of age has been encouraged. Currently licensed oral live vaccines have shown low risk of associated adverse events in the general population. Noteworthy, postmarketing reports of severe gastroenteritis with persistent vaccine viral shedding in children with severe combined immunodeficiency (SCID) have led companies to include this inborn error of immunity as an additional contraindication. SCID is not usually screened in newborns from developing countries. Therefore, the administration of live attenuated vaccines represents the first contact of these patients with life-threatening pathogens. We describe a clinical case of an infant with SCID who suffered from persistent rotavirus symptomatic diarrhea after receiving the rotavirus oral vaccine and was found to be infected with the vaccine strain. This case attempts to contribute to the discussion of those diseases that need to be incorporated into a screening program since an early diagnosis permits clinicians to withhold live attenuated immunization.

La vacuna con el bacilo de Calmette-Guérin es una vacuna atenuada utilizada para prevenir formas graves de tuberculosis. Se aplica a los recién nacidos en países con alta prevalencia de tuberculosis. Pueden presentarse, después de su aplicación, complicaciones a nivel local, como supuración o adenopatías regionales. La enfermedad por diseminación del bacilo es infrecuente y ocurre, por lo general, en pacientes con alteraciones inmunitarias subyacentes. Se presenta el caso de un niño de 5 meses que ingresó por un cuadro de 2 meses de evolución con detención del aumento de peso y nódulos subcutáneos. Se sospechó enfermedad por diseminación del bacilo y se diagnosticó por la biopsia de las lesiones. Se realizó el tratamiento con tres drogas antituberculosas, y se recuperó clínicamente. Si bien se realizaron estudios inmunológicos, no logró demostrarse ninguna inmunodeficiencia como afección predisponente.
The bacillus Calmette-Guérin vaccine is an attenuated vaccine historically used to prevent severe forms of tuberculosis. It is applied to all newborns in countries with high prevalence of tuberculosis. Local complications, such as suppuration or regional adenopathies, may occur after application. Disease due to the spread of the bacillus is infrequent, usually occurring in a patient with an underlying immune alteration. We present the case of a 5-month-old child who was admitted due to a 2-month evolution with weight loss and subcutaneous nodules. Disease was suspected to be due to bacillus Calmette-Guérin dissemination, being diagnosed by biopsy of the lesions. Treatment was carried out with three antituberculous drugs, evolving towards clinical recovery. Although immunological studies were carried out, no immunodeficiency could be demonstrated as a predisposing condition.

Severe combined immunodeficiency (SCID) represents the most lethal form of primary immunodeficiency, with mortality rates of greater than 90% within the first year of life without treatment. Hematopoietic stem cell transplantation and gene therapy are the only curative treatments available, and the best-known prognostic factors for success are age at diagnosis, age at hematopoietic stem cell transplantation, and the comorbidities that develop in between. There are no evidence-based guidelines for standardized clinical care for patients with SCID during the time between diagnosis and definitive treatment, and we aim to generate a consensus management strategy on the supportive care of patients with SCID. First, we gathered available information about SCID diagnostic and therapeutic guidelines, then we developed a document including diagnostic and therapeutic interventions, and finally we submitted the interventions for expert consensus through a modified Delphi technique. Interventions are grouped in 10 topic domains, including 123 "agreed" and 38 "nonagreed" statements. This document intends to standardize supportive clinical care of patients with SCID from diagnosis to definitive treatment, reduce disease burden, and ultimately improve prognosis, particularly in countries where newborn screening for SCID is not universally available and delayed diagnosis is the rule. Our work intends to provide a tool not only for immunologists but also for primary care physicians and other specialists involved in the care of patients with SCID.

La enfermedad granulomatosa crónica es una inmunodeficiencia primaria infrecuente, debida a un defecto en la actividad microbicida de los fagocitos, originada por mutaciones en los genes que codifican alguna de las subunidades del complejo enzimático nicotinamida adenina dinucleótido fosfato oxidasa. La incidencia estimada es 1 en 250 000 recién nacidos vivos. Puede presentarse desde la infancia hasta la adultez, por lo general, en menores de 2 años. Las infecciones bacterianas y fúngicas, en conjunto con las lesiones granulomatosas, son las manifestaciones más habituales de la enfermedad. Los microorganismos aislados más frecuentemente son Aspergillus spp., Staphylococcus aureus, Serratia marcescens, Nocardia spp. Se reporta el caso clínico de un varón de 1 año de vida en el que se diagnosticó enfermedad granulomatosa crónica a partir de infecciones múltiples que ocurrieron simultáneamente: aspergilosis pulmonar invasiva, osteomielitis por Serratia marcescens y granuloma cervical por Enterobacter cloacae.
Chronic granulomatous disease is an uncommon primary immunodeficiency due to a defect of the killing activity of phagocytes, caused by mutations in any of the genes encoding subunits of the superoxide-generating phagocyte NADPH oxidase system. The incidence is 1 in 250 000 live births. It can occur from infancy to adulthood, usually in children under 2 years. Bacterial and fungal infections in association with granuloma lesions are the most common manifestations of the disease. Aspergillus species, Staphylococcus aureus, Serratia marcescens, Nocardia species are the most common microorganisms isolated. We describe here a case of a 1-year-old boy with chronic granulomatous disease and invasive pulmonary aspergillosis, Serratia marcescens osteomyelitis and Enterobacter cloacae cervical granuloma.
