Abstract
ObjectiveTo study the effect of the leukotriene receptor agonist montelukast combined with methylprednisolone on inflammatory response and peripheral blood lymphocyte subset content in children with mycoplasma pneumonia.MethodsSeventy-four children were enrolled and randomly divided into a standard treatment group and a montelukast plus methylprednisolone group. Serum levels of inflammatory cytokines and corresponding cytokines of T lymphocyte subsets were measured, and peripheral blood was collected to determine the T cell subset content.ResultsAt 3 days and 7 days after treatment, serum MCP-1, PCT, ICAM-1, CXCL8, CRP, IFN-γ, and IL-17 levels and peripheral blood Th1 and Th17 content were significantly decreased in both groups, while serum IL-4 and TGF-β levels and peripheral blood Treg and Th2 content were significantly increased. However, serum MCP-1, PCT, ICAM-1, CXCL8, CRP, IFN-γ, and IL-17 levels and peripheral blood Th1 and Th17 content were significantly lower while serum IL-4 and TGF-β levels and peripheral blood Treg and Th2 content were significantly higher in the montelukast plus methylprednisolone group compared with the control group.ConclusionMontelukast combined with methylprednisolone for the treatment of mycoplasma pneumonia can inhibit inflammatory responses and regulate levels of Th1/Th2 and Th17/Treg cells.
