The study was performed in 36 Chinese patients with enterovirus 71 (EV71) encephalitis and 141 patients with EV71-related hand, foot and mouth disease (HFMD) without encephalitis. Genotyping was done by the polymerase chain reaction-restriction fragment length polymorphism technique. Patients with EV71 encephalitis had a significantly higher frequency of the CCL2-2510GG genotypes when compared to patients with EV71-related HFMD without encephalitis (66.7 % vs. 41.8 %, p = 0.028). The frequency of CCL2-2510G alleles was also significantly higher among the patients with EV71 encephalitis than among patients with EV71-related HFMD without encephalitis (79.2 % vs. 64.9 %, OR = 2.1, 95 % CI = 1.1-3.8, P = 0.023). Significant differences were found in gender, age, fever days, white blood cell count, C-reactive protein level, blood glucose concentration, and CCL2 level among genotypes of CCL2-2510A/G in EV71-infected patients, but no significant differences were found in alanine aminotransferase, aspartate aminotransferase, or creatine kinase myocardial isozyme levels or in cerebrospinal fluid evaluations (except monocytes) in patients with EV71 encephalitis. These findings suggest that the CCL2-2510G allele is associated with susceptibility to EV71 encephalitis in Chinese patients.
