ObjectivesTo investigate the effects of Reduning combined with gamma globulin on symptom improvement and serum levels of interleukin-6 (IL-6), 25-hydroxyvitamin D[25-(OH)D] and lactate dehydrogenase (LDH) in children with severe mycoplasma pneumonia (MP).MethodsA total of 123 children with severe MP admitted to the Changzhou Cancer Hospital affiliated to Soochow University from May 2018 to April 2020 were selected as subjects and randomly divided into three groups: control Group-A, control Group-B and the observation group, with 41 cases in each group. Control Group-A was given with Reduning, control Group-B was treated with gamma globulin, while the observation group was treated with Reduning injection combined with gamma globulin. The clinical efficacy, symptom improvement, incidence of adverse reactions, serum levels of IL-6, 25-(OH)D, LDH, Toll-like receptor 4/myeloid differentiation factor 88 (TLR4/MyD88) signaling pathway and T lymphocyte subsets before and after treatment were statistically compared between the three groups.ResultsThe total effective rate of treatment in the observation group was higher than that in control Group-A and control Group-B (p<0.05); The time for body temperature, lung rales, and cough to return to normal in the observation group was shorter than that in control Group-A and control Group-B (p<0.05). After treatment, the observation group had lower serum levels of IL-6, LDH, and higher levels of 25-(OH)D compared with control Group-A and control Group-B (p<0.05). Moreover, the observation group had lower serum expressions of TLR4 and MyD88 (p<0.05), higher serum levels of CD4+, CD4+/CD8+, and lower CD8+ compared with control Group-A and control Group-B (p<0.05). No significant difference can be seen in the comparison of the incidence of adverse reactions between the three groups (p>0.05).ConclusionsReduning combined with gamma globulin in the treatment of severe MP is worthy of clinical promotion and application. With such a treatment regimen, the immune function of children with severe MP can be significantly enhanced, the inflammatory response can be suppressed, and symptom improvement can be promoted, further improving the treatment outcome.Copyright: © Pakistan Journal of Medical Sciences.
