Objective: To explore the association between human cytomegalovirus (HCMV) and epilepsy. Methods: Epilepsy patients (n = 112) in neurology clinic of our hospital during January 2012 and December 2014 were allocated to the case groups, including intractable epilepsy group (n = 96) and non-intractable epilepsy group (n = 16). Healthy individual (n = 120) who received physical examination during the same period were allocated to the control group. The expression of serum HCMV late gene pp67-RNA was detected by reverse transcription-polymerase chain reaction (RT-PCR). The expressions of serum HCMV immunoglobulin G (IgG), immunoglobulin M (IgM) and interleukin-6 (IL-6) were detected by enzyme-linked immunosorbent assay (ELISA). Serum hypersensitive c-reactive protein (hsCRP) was detected by latex-enhanced immunoturbidimetry. The electroencephalogram (EEG) of refractory epilepsy group, non-refractory epilepsy group and control group were recorded. Results: The expression of pp67-mRNA was significantly higher in intractable epilepsy group than non-intractable epilepsy group (P < 0.05) and control group (P < 0.001). The HCMV-IgG positive rate and HCMV-IgM positive rate were significantly higher in intractable epilepsy group than control group (both P < 0.001). The HCMV-IgM positive rate was significantly higher in intractable epilepsy group than non-intractable epilepsy group (P < 0.001). The HCMV-IgM positive rate was significantly higher in non-intractable epilepsy group than control group (P < 0.001). The hs-CRP and IL-6 levels presented descending trends respectively in intractable epilepsy group, non-intractable epilepsy group and control group (all P < 0.001). Conclusion: HCMV was prominently expressed in epilepsy and might contribute to the development of epilepsy.
