Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the respiratory distress condition known as COVID-19. This disease broadly affects several physiological systems, including the gastrointestinal, renal, and central nervous (CNS) systems, significantly influencing the patient’s overall quality of life. Additionally, numerous risk factors have been suggested, including gender, body weight, age, metabolic status, renal health, preexisting cardiomyopathies, and inflammatory conditions. Despite advances in understanding the genome and pathophysiological ramifications of COVID-19, its precise origins remain elusive. SARS-CoV-2 interacts with a receptor-binding domain within angiotensin-converting enzyme 2 (ACE2). This receptor is expressed in various organs of different species, including humans, with different abundance. Although COVID-19 has multiorgan manifestations, the main pathologies occur in the lung, including pulmonary fibrosis, respiratory failure, pulmonary embolism, and secondary bacterial pneumonia. In the post-COVID-19 period, different sequelae may occur, which may have various causes, including the direct action of the virus, alteration of the immune response, and metabolic alterations during infection, among others. Recognizing the serious adverse health effects associated with COVID-19, it becomes imperative to comprehensively elucidate and discuss the existing evidence surrounding this viral infection, including those related to the pathophysiological effects of the disease and the subsequent consequences. This review aims to contribute to a comprehensive understanding of the impact of COVID-19 and its long-term effects on human health.

“…Inborn errors of immunity (IEI) are a group of phenotypically and genetically diverse disorders characterized by monogenic defects affecting human immunity 1 . Patients with IEI have an increased susceptibility to infections, autoimmunity, autoinflammation, allergy, and the development of malignancies 2 , 3 . Accurate diagnosis of these conditions is essential for tailoring management protocols.…”

Inborn errors of immunity (IEI) are a heterogeneous group of monogenic disorders that include primary immunodeficiency’s and other disorders affecting different aspects of the immune system. Next-Generation Sequencing (NGS) is an essential tool to diagnose IEI. We report our 3-year experience in setting up facilities for NGS for diagnosis of IEI in Chandigarh, North India. We used a targeted, customized gene panel of 44 genes known to result in IEI. Variant analysis was done using Ion Reporter software. The in-house NGS has enabled us to offer genetic diagnoses to patients with IEI at minimal costs. Of 121 patients who were included pathogenic variants were identified in 77 patients. These included patients with Chronic Granulomatous Disease, Severe Combined Immune Deficiency, leukocyte adhesion defect, X-linked agammaglobulinemia, Ataxia Telangiectasia, Hyper-IgE syndrome, Wiskott Aldrich syndrome, Mendelian susceptibility to mycobacterial diseases, Hyper-IgM syndrome, autoimmune lymphoproliferative syndrome, and GATA-2 deficiency. This manuscript discusses the challenges encountered while setting up and running targeted NGS for IEI in our unit. Genetic diagnosis has helped our patients with IEI in genetic counselling, prenatal diagnosis, and accessing appropriate therapeutic options.

“…Tabela 1 -10 Sinais de alerta para IDPs, adaptados para o Brasil (Adultos e Crianças) Adaptado de ASBAI/BRAGID (www.asbai.org.br / www.bragid.org.br) Em geral, a incidência das IDPs é apenas estimada, mas estudos recentes têm demonstrado que elas podem ser muito mais comuns do que se pensava, o que podemos perceber com o número crescente de pacientes diagnosticados por todo mundo e os novos genes constantemente identificados, como apresentado na Figura 1 B [4,18]. A última estimativa da prevalência de IDPs afirma que, entre 1-2% da população mundial apresenta algum tipo de IDP [19], e que pode ser ainda maior em populações com alta taxa de consanguinidade ou geneticamente isoladas [7].…”

Oliveira, T.S. Epidemiological study on Chronic Granulomatous Disease (CGD): Clinical and demographic characteristics. Chronic Granulomatous Disease (CGD) is a primary immunodeficiency characterized by a deficiency in the production of reactive oxygen species (ROS) due to deleterious genetic variants in one of the genes (e.g., CYBB, CYBA, NCF1, NCF2 and NCF4) that encode the proteins of the NADPH oxidase complex, resulting in defective microbicidal activity and susceptibility to infections. It presents the X-linked (CYBB) and autosomal recessive forms, both with onset of manifestations in the first 2 years of life. Larger-scale epidemiological studies on CGD in Brazil are rare and the characterization of these patients within a continental block with similar physical and geopolitical characteristics is of special importance for their understanding and dissemination. Therefore, this study aimed to determine the clinical, geospatial, molecular and genetics characteristics of 238 patients with CGD, 196 males and 42 females from 8 countries (Mexico,
