RESUMEN
<p><b>OBJECTIVE</b>To explore the clinical efficacy of the combined therapy of zinc supplement and Jinye Baidu granule (JBG) on human cytomegalovirus (HCMV) infection.</p><p><b>METHODS</b>One hundred and forty patients with positive HCMV-IgM were randomly divided into four groups, with 35 cases in each group, that is, the control group (only medicated with JBG), the high-, moderate- and low-dose zinc combined groups (treated with JBG combined with zinc gluconate tablet at dose of 30 mg, 20 mg, 10 mg every day respectively). The negative conversion rate of HCMV-IgM was observed.</p><p><b>RESULTS</b>Insignificant difference in the negative conversion rate was shown in comparison of the control group with the low dose group (P > 0.05), and in comparison of the high dose with the moderate dose group (P > 0.05); however, the rate was significantly lower in the control group than that in the moderate dose and high dose group (P < 0.05).</p><p><b>CONCLUSION</b>Combined therapy of zinc supplement and JBG can significantly increase the negative conversion rate of HCMV-IgM. The optimal dosage of zinc gluconate tablet was 20 mg once a day.</p>
