    Abstract:
    OBJECTIVE: To explore the possible relationship between the -2518 A/G single nucleotide polymorphisms in monocyte chemoattractant protein-1 (MCP-1) gene of Chinese Han population and the susceptibility to pulmonary tuberculosis. METHODS: A 1:1 matched case-control study was conducted from March 2008 to August 2008. The - 2518 MCP-1 A/G polymorphisms were detected in 167 pairs of subjects by reaction-restriction fragment length polymorphism (PCR-RLFP) technique. General characteristics, current disease history, past medical history and related environmental factors of tuberculosis were collected using a questionnaire designed by ourselves. Univariate analyses and multivariate conditional logistic analyses were conducted. RESULTS: The genotype frequencies of AA, GA and GG in the case group and the control group were 21/167 (12.6%), 62/167 (37.1%), 84/167 (50.3%) and 42/167 (25.2%), 83/167 (49.7%), 42/167 (25.1%), respectively. There was a significant difference in genotype frequencies between the case and the control groups in the univariate analysis (chi2 = 24.041, P<0.01). The significant association remained after adjusting environmental factors between genotype GG (OR 1.989, 95% CI 1.154 - 3.428, chi2 = 6.124, P<0.05) and the susceptibility to pulmonary tuberculosis. CONCLUSION: The -2518 MCP-1 GG genotype might be associated with susceptibility to pulmonary tuberculosis in Chinese Han population.
