Serum IL-32 level in children with bacterial pneumonia and its relationship with disease severity / 中国基层医药

ABSTRACT

Objective:To investigate the serum interleukin-32(IL-32) level in children with bacterial pneumonia and its relationship with the severity of the disease.Methods:From January 2019 to December 2019, 300 children with bacterial pneumonia in Taizhou Cancer Hospital were selected as the pneumonia group, and 300 healthy children in our hospital were selected as control group.The serum levels of IL-32, IL-6, IL-8 and tumor necrosis factor-α(TNF-α) were measured by double antibody sandwich enzyme-linked immunosorbent assay.Results:The serum levels of IL-32[(212.46±16.74)ng/L], IL-6[(0.29±0.06)μg/L], IL-8[(0.41±0.08)μg/L] and TNF-α[(1.15±0.11)μg/L] in the pneumonia group were higher than those in the control group[(116.51±14.52)ng/L, (0.07±0.02)μg/L, (0.09±0.03)μg/L, (0.14±0.03)μg/L](all P<0.05). The serum levels of IL-32[(128.76±15.42)ng/L], IL-6[(0.15±0.04)μg/L], IL-8[(0.16±0.05)μg/L] and TNF-α[(0.29±0.06)μg/L] in children with pneumonia during recovery were lower than those in early stage[(212.46±16.74)ng/L, (0.29±0.06)μg/L, (0.41±0.08)μg/L, (1.15±0.11)μg/L](all P<0.05). The levels of serum IL-32[(232.16±16.02)ng/L], IL-6[(0.37±0.08)μg/L], IL-8[(0.54±0.09)μg/L], TNF-α[(1.42±0.15)μg/L] in the severe pneumonia group were higher than those in the non-severe pneumonia group[(184.26±16.31)ng/L, (0.23±0.05)μg/L, (0.26±0.06)μg/L, (0.79±0.12)μg/L](all P<0.05). There were positive correlation between serum IL-32 level and IL-6( r=0.602), IL-8( r=0.624), TNF-α( r=0.593) levels in children with pneumonia(all P<0.05). Conclusion:The serum IL-32 level is elevated in children with bacterial pneumonia.The serum IL-32 level can reflect the therapeutic effect, severity and inflammatory response of children with bacterial pneumonia.
