Primary immunodeficiency disorders in Sweden: cases among children, 1974-1979
Abstract:
A nationwide survey of symptomatic primary immunodeficiency disorders in children in Sweden during the 6-year period 1974-1979 resulted in 201 reported cases. The reported data for 174 children were analyzed. Antibody deficiencies were the most frequent (45.0%), followed by phagocytic disorders (22.0%) and combined T- and B-cell disorders (20.8%). Thirty-two children (18.4%) died, with the highest mortality for combined T- and B-cell defects. The sex ratio for all disorders was 2:1 for boys:girls. Neutropenia was significantly more common in the northern part of Sweden.

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.
