Abstrakt: Chemokines are chemotactic cytokines that are mainly involved in the migratory patterns of immune cells. Few studies have evaluated the levels of chemokines in children with acute bacterial infections. The aim of this study was to evaluate the serum levels of chemokines MCP-1, RANTES, MIG and IP-10 in children with sepsis, community-acquired pneumonia (CAP) and skin abscess. Serum levels of MCP-1, RANTES, MIG and IP-10 were measured in 37 children with sepsis, 27 children with CAP, 25 children with skin abscess and 20 controls with no signs of infection. Patients with sepsis, CAP and skin abscess had higher concentrations of RANTES compared to controls (P = 0.0057, P = 0.0004 and P = 0.0108, respectively). IP-10 values were higher in patients with sepsis compared to children with skin abscess (P = 0.0075). However, MCP-1 levels were lower in septic patients compared to controls (P = 0.0136). There was no difference on MIG concentrations between the groups. Our original findings observed that RANTES was consistently elevated in all types of infections suggesting this chemokine may play an important role in the pathogenesis of bacterial infection. Additionally, patients with sepsis had a unique pattern of response with high levels of IP-10 but low levels of MCP-1, which should be further explored as the markers of disease severity.
