In this study we have determined the serum tumor necrosis factor-alpha
(TNF-alpha), soluble CD8 (sCD8) and soluble interleukin-2 receptor (s
IL-2R) levels in children with active pulmonary tuberculosis (n=66) an
d healthy controls (n=20). Measurable serum TNF-alpha levels were dete
cted in nine of 86 children (10.5%), all of whom belonged to the group
with active disease. Se,rum sCD8 and sIL-2R determinations revealed a
significant difference between the group with active pulmonary tuberc
ulosis and the controls (p<0.05). Deeper insight into the involvement
of cytokines and T cells,vip provide a better understanding of the pat
hogenesis of tuberculosis in children.
