Case report: Virus-induced hemophagocytic lymphohistiocytosis in a patient with APECED.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), also known as autoimmune polyglandular syndrome type 1 (APS-1) is a rare autosomal recessive inborn error of immunity (IEI), which is accompanied by immune dysregulation. Hypoparathyroidism, adrenocortical failure and candidiasis are its typical manifestations. Here we report about recurrent COVID-19 in a 3-year-old boy with APECED, who developed retinopathy with macular atrophy and autoimmune hepatitis after the first episode of SARS-CoV-2 infection.

Newborn screening for severe combined immunodeficiency: The results of the first pilot TREC and KREC study in Ukraine with involving of 10,350 neonates.

Severe combined immunodeficiency (SCID) is a group of inborn errors of immunity (IEI) characterized by severe T- and/or B-lymphopenia. At birth, there are usually no clinical signs of the disease, but in the first year of life, often in the first months the disease manifests with severe infections. Timely diagnosis and treatment play a crucial role in patient survival.

Evaluation of awareness about primary immunodeficiencies among physicians before and after implementation of the educational program: A longitudinal study.

Increasing physicians' awareness is one of the main ways to improve early diagnosis of rare diseases. A survey among physicians of different specialties to evaluate the knowledge about primary immunodeficiencies (PID) was conducted in 2016 and in 2019 -before and after the implementation of an educational program. We compare responses from 82 doctors who participated in the 2016 survey, and 67 doctors who have taken part in the survey in 2019: pediatricians, general practitioners / family physicians and physicians of pediatric sub specialties.

Novel compound heterozygous variants in NHLRC2 in a patient with FINCA syndrome.

Two variants in the ubiquitously expressed NHLRC2 gene have been reported to cause a lethal fibrotic cerebropulmonary disease termed fibrosis, neurodegeneration, and cerebral angiomatosis (FINCA) syndrome in three Finnish children. Our objective was to determine the genetic basis of disease in a new patient with clinical features of FINCA syndrome using whole-exome sequencing (WES) and confirmation by Sanger sequencing. The patient has one known and one novel variant in NHLRC2 (c.

The impact of combining educational program with the improving of infrastructure to diagnose on early detection of primary immunodeficiencies in children.

Early detection of primary immunodeficiency diseases (PID) is vital for adequate prevention and management of PID infectious complications. The objective of this study was to evaluate the impact of a model combining physician education and public awareness with the infrastructure to diagnose PID to improve its early detection in children. Three approaches were combined and the results were followed from February 2017 to February 2019 in Ternopil region, Ukraine: the education of primary care physicians and other specialists on early PID detection using workshops, trainings, and targeted publications; organization of public events and media appearances to raise PID awareness; performing immunological testing for patients with suspected PID.
