The Healthcare Study Examines the Humoral Anti-S1 Antibody Response Following mRNA Vaccination, Comparing Individuals with and without Prior SARS-CoV-2 Infection.

Vaccines targeting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been pivotal in curtailing the spread of infection. Health care workers, as frontline responders, were among the first to receive vaccination to mitigate coronavirus disease in 2019 (COVID-19) transmission. This study aimed to assess the humoral response elicited by mRNA vaccines, specifically measuring antibodies against the spike S1 protein, a marker of immune response.

Facilitated subcutaneous immunoglobulin treatment patterns in pediatric patients with primary immunodeficiency diseases.

This retrospective study investigated real-world hyaluronidase-facilitated subcutaneous immunoglobulin (fSCIG) treatment patterns in pediatric patients with primary immunodeficiency diseases (PIDs) in Poland. Clinical and demographic information, fSCIG treatment parameters and clinical outcomes were extracted from medical records of 28 participants (aged ≤18 years) with PIDs who received fSCIG. 18 participants (64.

Long-term and real-world safety and efficacy of retroviral gene therapy for adenosine deaminase deficiency.

Adenosine deaminase (ADA) deficiency leads to severe combined immunodeficiency (SCID). Previous clinical trials showed that autologous CD34 cell gene therapy (GT) following busulfan reduced-intensity conditioning is a promising therapeutic approach for ADA-SCID, but long-term data are warranted. Here we report an analysis on long-term safety and efficacy data of 43 patients with ADA-SCID who received retroviral ex vivo bone marrow-derived hematopoietic stem cell GT.

Transcriptome profiling of regulatory T cells from children with transient hypogammaglobulinemia of infancy.

Transient hypogammaglobulinemia of infancy (THI) is one of the most common forms of hypogammaglobulinemia in the early childhood. THI is usually associated with chronic, recurrent bacterial and viral infections, life-threatening in some cases, yet its pathogenesis is still largely unknown. As our previous findings indicated the possible role of Treg cells in the pathomechanism of THI, the aim of the current study was to investigate gene expression profile of Treg cells isolated from THI patients.

SARS-CoV-2 and thyroid diseases.

SARS-CoV-2 virus responsible for acute respiratory disease affected other organs leading to co-existence symptoms or complications. Thyroid gland was one of them due to expression of angiotensin-converting enzyme 2 (ACE2), the protein facilitating viral binding to the host cells. Moreover, thyroid gland, important for regulation of hormonal network, is extremely sensitive to any changes in homeostasis and metabolism.
