CCR2 V64I (G/A), monocyte chemoattractant protein-1 (MCP-1) -2518 A/G, stromal cell derived factor-1alpha; (SDF-1alpha) 3'UTR G/A and DC-SIGN gene polymorphisms were studied by polymerase chain reaction based methods in HIV-1 infected patients without TB (n=151), with pulmonary TB (PTB) (n=81) and extrapulmonary TB (n=31), 155 PTB patients without HIV and 206 healthy controls.
In conclusion, we hypothesize that although carriers of CD209 -336A allele are more sensitive to infection with a Beijing strain, a combination of human CD209 -336G allele and M. tuberculosis Beijing genotype leads more frequently to the lethal outcome in pulmonary TB male patients in Russian (Caucasian) population.
The <i>TNF-α</i> -238 A allele appeared a protective effect against STB, whereas the <i>SP110</i> SNPs (rs722555 and rs1135791) and <i>TNF-α</i> -308G>A (rs1800629) showed no association with susceptibility to PTB and STB patients in southern China.
In the present study, we investigated whether variants in the TLR-1 1805T/G (Ile602Ser), TLR-2 2258G/A (Arg753Gln), TLR-4 896A/G (Asp299Gly), TLR-4 1196C/T (Thr399Ile), TLR-6 745C/T (Ser249Pro), TIRAP 975C/T (Ser180Leu) genes and TLR-9 promoter region polymorphisms at positions -1237C/T and -1486C/T are associated with susceptibility or resistance to pulmonary tuberculosis (PTB).
In the comparison of TAP2 gene with the DRB1*08:03, which is associated with TAP2*Bky2 and PTB in Koreans, we demonstrated the hierarchy of these association factors.
In this study, we have investigated the relationship between <i>ILB</i>, <i>IL6,</i> and <i>TNFα</i> polymorphisms and a predisposition to <i>Mycobacterium tuberculosis</i> (MTB) infection and PTB.
We developed a Markov microsimulation model of hypothetical cohorts of 100,000 individuals undergoing diagnostic sputum evaluation with Xpert for suspected pulmonary TB, in each of 3 emblematic settings: an HIV clinic in South Africa, a public TB center in India, and an adult primary care setting in China.
A stratified analysis by ethnicity revealed that the NRAMP1 3'UTR polymorphism was associated with an increased risk of PTB in the Asian population, but not in Caucasian, African, and South American populations.The present results indicate that the NRAMP1 3'UTR polymorphism may be considered a risk factor for PTB in the Asian population.
The present study was undertaken to explore the relationship of Toll-like receptor (TLR) 2, TLR4 genes polymorphisms with Pulmonary tuberculosis (PTB) risk in a sample of Chinese population.
More important, the meta-analysis results indicated that the serum MBL levels in patients with PTB were significantly lower than those in healthy controls (SMD = 0.43, 95% CI = 0.33-0.52).
No convincing evidence of association between MBL sequence variants and PTB was observed individually, although the low-producing XB haplotype group may serve as a minor risk factor for PTB infection in the male Chinese Han population.
This study confirmed the association of SNPs in BsmI (B/b + b/b) of VDR and SNPs in -308A (G/A +G/G) of TNF-alpha genes with susceptibility to tuberculosis in Iranian PTB patients.
We investigated the polymorphisms in the 5' regulatory region of VDR gene in 206 normal healthy subjects and 166 patients with pulmonary tuberculosis from south India.
Furthermore, combinations of polymorphisms with IFN-γ -874 were associated with LTBI, whereas combinations with IL10 - 1082 were more likely associated with PTB.
On the contrary, minor allele "A" of rs2069705 in <i>IFNG</i> significantly increased the risk of PTB under genotype, dominant and additive model (<i>P</i><0.05).
