IP-10 identifies Mtb. infection regardless of reason for
admission
To reflect daily pediatric clinical practice, we performed a subgroup
analysis regarding the reason for hospital admission (Figure 2). In
children with clinical suspicion of TB, IP-10 concentration was
significantly higher in ATB group than in non-TB group (p <
0.0001). Similarly, in contact tracing referrals, Mtb.- infected
children expressed higher levels of IP-10 than TB contacts (p
< 0.0001), also when ATB and LTBI groups were compared
separately (p < 0.0001 for both comparisons).
