Objective:
To evaluate the susceptibility of pulmonary tuberculosis based on the single nucleotide polymorphism (SNP) of Toll like receptor 4 (TLR4) gene.
Methods:
We searched PubMed, Web of science, EMBASE, and Chinese National Knowledge Infrastructure (CNKI) databases using mesh words: "tuberculosis", "pulmonary", "TLR4", "SNP", "Toll like receptor 4", "nucleotide polymorphism" for studies on the relations between TLR4 SNP polymorphism and the risk of pulmonary tuberculosis that were published before September 1st, 2021. Papers were selected according to the inclusion and exclusion criteria established in advance. The allele and genotype data of the four most widely studied SNP loci (rs4986791, rs4986790, rs11536889, rs10759932) in TLR4 gene were extracted and analyzed by Review Manager 5.3 software.
Results:
20 studies including a total of 24727 patients were included in the final meta-analysis. Results of the meta-analysis showed that the C allele of rs10759932 increased the risk of pulmonary tuberculosis (odds ratio - OR: 1.144; 95% confidence interval (CI) 1.043-1.254, P = 0.004). Compared with TT genotype, CC+CT genotype of rs10759932 and CT alone genotype significantly increased the risk of pulmonary tuberculosis (OR = 1.218, 95% CI 1.084-1.369, P = 0.001; OR = 1.227, 95% CI 1.085-1.387, P = 0.001). However, rs4986790, rs4986791 and rs11536889 had no significant correlation with the susceptibility of pulmonary tuberculosis (P > 0.05).
Conclusion:
G allele GG+GA genotype, and the GA genotype of rs4986790; C allele, CC+CT genotype, and the CC genotype of rs10759932 increased the risk of pulmonary tuberculosis, and may potentially be used as a marker for pulmonary tuberculosis diagnosis and monitoring.

Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
