    ABSTRACT: To study the correlation between polymorphisms of genes with susceptibility to tuberculosis and the clinical characteristics of tuberculosis in Han population. Four hundred and fifty-nine tuberculosis inpatients of Han population in Shanghai Pulmonary Hospital from Jan 2007 to Dec 2008 were recruited. The clinical characteristics of tuberculosis (gender, fever, extent of lesions, cavity formation, hemoptysis, initial treatment and retreatment) were observed. The polymorphisms of VDR gene (variants in FokI and TaqI), NRAMP1 gene (variants in INT4, D543N and 3 UTR), MBL gene (variants in HL, YX and QP) and IFNG gene (variants in 874AT) were genotyped by a variety of SNP genotyping techniques. The correlation between polymorphisms of genes with susceptibility to tuberculosis and the clinical characteristics of the disease was analyzed by ANOVAs. The frequency of CC, CT and TT variants of FokI in VDR gene in cases with fever were 54.7% (29/53), 13.2% (7/53) and 32.1% (17/53), respectively, compared to 40.6% (52/128), 30.5% (39/128) and 28.9% (37/128) in cases without fever, the difference being significant (χ² = 6.183, P < 0.05). In patients with CT variants, 15.2% (7/46) had fever, while in patients with non-CT variants, 34.1% (46/135) had fever (χ² = 5.891, P < 0.05), suggesting that patients with CT variants were less likely to have fever. The frequencies of TT + TC and CC variants of QP in the MBL gene in initial treatment cases were 28.3% (60/212) and 71.7% (152/212), respectively, compared to 19.1% (41/215) and 80.9% (174/215) in retreatment cases, the difference being significant (χ² = 5.038, P < 0.05). No significant correlation was observed between the other variants and the clinical characteristics of tuberculosis (χ² = 0.001 - 2.732, P > 0.05). The polymorphisms of FokI in VDR gene was associated with fever among the clinical characteristics of tuberculosis, and patients with CT variants might be protected from fever. The polymorphisms of QP in MBL gene might be associated with recurrence of tuberculosis.

    ABSTRACT: To investigate the distribution of polymorphisms of SLC11A1 gene, VDR gene, MBL gene and IFNG gene with susceptibility to tuberculosis (TB) in Chinese Han population suffering from drug-sensitive TB and drug-resistant TB so as to identify the correlation between gene polymorphisms and the development of drug-resistant TB. Single nucleotide polymorphisms (SNP) of VDR gene, SLC11A1 gene, MBL gene, IFNG gene were typed and analyzed by pyrosequencing, Real-time Probe and SNaPshot among 229 patients with drug-sensitive TB and 230 patients with drug-resistant TB. The polymorphic foci of VDR gene from the drug-sensitive TB group and the drug-resistant TB group showed no significant difference (P > 0.05). The genotype of INT4 site and allelic frequency of SLC11A1 gene for drug-sensitive TB group were significantly different from those for drug-resistant TB group (P = 0.031, 0.046). If recessive inheritance was assumed, the genotypes of INT4 site from the two groups were significantly different (OR = 5.756, 95%CI: 1.261 - 26.269, P = 0.011). Considering the relationship between OR values under various combination, our findings confirmed that the genetic mode of INT4 site was in accordance with recessive inheritance. The genotypes of Q/P site and allelic frequencies of MBL gene from drug-sensitive and drug-resistant groups were significantly different (P = 0.029, 0.033). The difference still existed under the hypothesis of recessive inheritance (OR = 9.290, 95%CI: 1.167 - 73.949, P = 0.011). The polymorphic foci of IFNG gene from the two groups showed no significant difference. INT4 sites on SLC11A1 gene and Q/P site on MBL gene were probably associated with the development of drug-resistant TB in Chinese Han population. Further study on this issue would be helpful in locating the population at high risk of drug-resistant TB and exploring the effective intervention to decrease the incidence of this disease.
