Abstract:
Since coronavirus disease 2019 (COVID-19) became a global pandemic, concerns have arisen regarding the risks of COVID-19 in immunocompromised children and adolescents. Here we aimed to evaluate the clinical outcomes and risks of severe COVID-19 in immunocompromised pediatric patients. Previous studies reported that most children and adolescents receiving immunosuppressive medications have clinical presentations and favorable outcomes similar to those of the general pediatric population. Treatments and access to health services should not be interrupted in these populations, and continuous monitoring of the potential impact of variant strains on the risk of immunocompromised pediatric patients is warranted.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
