Clinical Observation on Shuanghuanglian powder in treating viral myocarditis of childrenin treating viral myocarditis of children

Objective: To study immune function of children viral myocarditis and to evaluate the clinical effect of Shuanghuanglian Powder (SHLP) by injection.Methods: The 62 patients of viral myocarditis were divided into two groups randomly, the SHLP group (n = 32) treated with conventional therapy plus SHLP and the conventional treatment group (n = 30) with conventional therapy alone. Their serum antibody of Coxsackie virus group B (COXB-IgM), T-lymphocyte subsets including CD₃ ⁺, CD₄ ⁺, CD₈ ⁺ and CD₄ ⁺/CD₈ ⁺ were determined with ELISA and indirect immunofluorescent assay.Results: COXB-IgM was positive in 39 of the 62 patients, which was significantly different with those of normal controls (P< 0.001). Patients’ serum level of CD₄ ⁺ cells and CD₄ ⁺/CD₈ ⁺ ratio decreased while CD₈ ⁺ increased. After treatment, the recovery of symptoms, signs and immune function in patients of the SHLP group were significantly better than those in patients treated with conventional treatment alone (P<0.01).Conclusion: Immunoregulatory disturbance is involved in children with viral myocarditis and SHLP is an effective drug in the treatment of children viral myocarditis.
