Abstract
Background Mannose-binding lectin (MBL2) is considered to play a role in the human innate immune response to tuberculosis (TB) infections, and 4 common single nucleotide polymorphisms (SNPs) may be associated with pulmonary tuberculosis (PTB) risk. To examine these potential associations, we performed a comprehensive analysis to assess the relationships between MBL2 polymorphisms and PTB. Methods The PubMed, Embase, and SinoMed databases were searched for articles published prior to June 13, 2019. Odds ratios with 95% confidence intervals were calculated to evaluate the strength of the relationships. Results There were 37 case-control studies examining the effects of the four SNPs in MBL2 on PTB. A positive association between rs11003125 and PTB risk was observed in the hospital-based subgroup. Moreover, for the combined polymorphism and PTB risk, positive associations were detected not only in the total population but also in those with Asian origins across all source of control subgroups. No associations were found for rs7096206 or rs7095891. Conclusions Our current study indicated that several SNPs in MBL2 may be associated with susceptibility to PTB.

Abstract
BACKGROUND Immune- and inflammation-related genes (IIRGs) play an important role in the pathogenesis of tuberculosis (TB). However, the relationship between IIRG polymorphisms and TB risk remains unknown. In this study, the gene polymorphisms and their association with tuberculosis were determined in a Chinese population. METHODS We performed a case-control study involving 1016 patients with TB and 507 healthy controls of Han Chinese origin. Sixty-four single-nucleotide polymorphisms (SNPs) belonging to 18 IIRGs were genotyped by the PCR-MassArray assay, and the obtained data was analyzed with χ2-test, Bonferroni correction, and unconditional logistic regression analysis. RESULTS We observed significant differences in the allele frequency of LTA rs2229094*C (P = 0.015), MBL2 rs2099902*C (P = 0.001), MBL2 rs930507*G (P = 0.004), MBL2 rs10824793*G (P = 0.004), and IL12RB1 rs2305740*G (P = 0.040) between the TB and healthy groups. Increased TB risk was identified in the rs930507 G/G genotype (Padjusted = 0.027) under a codominant genetic model as well as in the rs2099902 (C/T + C/C) vs T/T genotype (Padjusted = 0.020), rs930507 (C/G + G/G) vs C/C genotype (Padjusted = 0.027), and rs10824793 (G/A + G/G) vs A/A genotype (Padjusted = 0.017) under a dominant genetic model after Bonferroni correction in the analysis of the overall TB group rather than the TB subgroups. Furthermore, the rs10824793_rs7916582*GT and rs10824793_rs7916582*GC haplotypes were significantly associated with increased TB risk (P = 0.001, odds ratio [OR] = 1.421, 95% confidence interval [CI]: 1.152-1.753; and P = 0.018, OR = 1.364, 95% CI: 1.055-1.765, respectively). Moreover, the rs10824793_rs7916582*AT/AT or rs10824793_rs7916582*GT/GT diplotype showed a protective (P = 0.003, OR = 0.530, 95% CI: 0.349-0.805) or harmful (P = 0.009, OR = 1.396, 95% CI: 1.087-1.793) effect against the development of TB. CONCLUSIONS This study indicated that MBL2 polymorphisms, haplotypes, and diplotypes were associated with TB susceptibility in the Han Chinese population. Additionally, larger sample size studies are needed to further confirm these findings in the future.

Association between the mannose-binding lectin (MBL)-2 gene variants and serum MBL with pulmonary tuberculosis: An update meta-analysis and systematic review. Microb Pathog 2019; 132:374-380. [PMID: 30999018 DOI: 10.1016/j.micpath.2019.04.023] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2019] [Revised: 03/21/2019] [Accepted: 04/12/2019] [Indexed: 02/05/2023]
Abstract
In recent years, many studies have demonstrated that the MBL-2 gene polymorphisms may be associated with pulmonary tuberculosis (PTB) susceptibility. Moreover, some studies have shown that serum MBL levels were influenced by the MBL-2 gene polymorphisms and that it plays an important role in tuberculosis infection. However, the results of these studies were inconsistent and underpowered. The current meta-analysis and systematic review aimed to evaluate the association between the MBL-2 gene polymorphisms and serum MBL levels with PTB. Finally, 30 eligible articles were included in the study. The overall results indicated that the MBL-2 rs1800450 (54 A/B) and rs5030737 (52 A/D) polymorphisms were risk factors for PTB, but the MBL-2 rs1800451 (57 A/C) and rs7095891 (+4 P/Q) polymorphisms as protective factors against PTB. No associations were found in the other three polymorphisms (exon 1, rs7096206 (-221 X/Y), and rs11003125 (-550 H/L) of the MBL-2 gene. In addition, we could not detect any significant differences between haplotypes among PTB patients and healthy controls. 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). This study suggested that the MBL-2 gene polymorphisms may be involved in the pathogenesis of PTB, and serum MBL may be a biomarker for the diagnosis of PTB. More rigorous research is needed in the future to confirm these findings further.

Abstract
BACKGROUND Tuberculosis (TB) incidence remains low in health departments of Castellon and La Plana-Vila-real, but TB elimination is challenging. The objective of this study was to estimate associated factors of pulmonary tuberculosis (PTB) compared with extrapulmonary tuberculosis (ETB) and investigate epidemiological characteristics of these pathologies to orient control and prevention actions. MATERIALS AND METHODS A prospective case-case study was implemented by comparing PTB and ETB incidences during 2013-2016 from notification reports, epidemiological surveillance, and microbiological results of hospitals' laboratories Hospital General Castellon and La Plana-Vila-Real in the province of Castellon of Valencia region in Spain. In this design, cases were patients with PTB and controls were patients with ETB. Directed acyclic graph approach was used for selection of potential risk and confounding factors. Adjusted odds ratios (AORs) were estimated by logistic regression models. RESULTS The study included 136 patients with PTB and 57 patients with ETB, with microbiological confirmation of 93.4% and 52.6%, and the annual median of incidence rates were 7.5 and 3.1 per 100 000 inhabitants, respectively. In general, patients with PTB were younger with higher male proportion than patients with ETB. Risk factors of PTB were smoking tobacco (AOR = 3.98; 95% confidence interval [CI] = 1.66-9.56), social problems (social marginalization, homeless, residence in shelters for the poor, or stay in prison) (AOR = 3.39; 95% CI = 1.05-10.94), and contact with patients with TB (AOR = 2.51; 95% CI = 1.06-5.95). No-smoking tobacco and no-drug abuse interaction decrease PTB risk (AOR = 0.27; 95% CI = 0.12-0.64). From these results, specific measures of health promotion and prevention can be addressed. CONCLUSIONS The estimated associated factors of PTB may be prevented, and it was demonstrated that the case-case design is useful in the study of TB.

Abstract
INTRODUCTION The association of mannose-binding lectin gene (MBL2) polymorphisms with tuberculosis susceptibility was inconclusive. In this study, a meta-analysis of 22 case-control studies was carried out to assess the effect of MBL2 polymorphisms on tuberculosis risk. MATERIAL AND METHODS A search was performed in Embase, PubMed and Web of Science up to Sep 30, 2015. Odds ratio (OR) and 95% confidence interval (95% CI) were used to assess the association. Statistical analyses were performed using STATA 12.0 software. RESULTS rs1800451 was associated with a decreased tuberculosis risk in the allele model (C vs. A: OR = 0.93, 95% CI: 0.86-1.00, p = 0.050). In analyses stratified by ethnicity, rs7096206 (C/G: OR = 1.31, 95% CI: 1.10-1.57, p = 0.003; GG vs. GC + CC: OR = 0.69, 95% CI: 0.56-0.85, p < 0.001) and A/O (O/A: OR = 1.34, 95% CI: 1.10-1.64, p = 0.004) were associated with tuberculosis risk in Asians, A/O (AA vs. AO + OO: OR = 0.71, 95% CI: 0.51-0.99, p = 0.041) and rs1800451 (AC vs. AA + CC: OR = 2.70, 95% CI: 1.27-5.74, p = 0.010) were associated with tuberculosis risk in Americans, and rs1800451 (C/A: OR = 0.92, 95% CI: 0.86-0.99, p = 0.035) was associated with tuberculosis risk in Africans. Additionally, rs1800450 (B/A: OR = 0.42, 95% CI: 0.25-0.72, p = 0.001) was associated with tuberculosis risk in Europeans. CONCLUSIONS The MBL2 rs1800451 polymorphism is associated with decreased TB risk in the general population, and A/O, rs7096206, rs1800450 and rs1800451 are likely to be associated with the risk for some specific ethnic groups.

Abstract
Background Evidence suggests that genetic variations of exon 1 of mannose-binding lectin 2 (MBL2) may contribute to tuberculosis (TB) risk. Many studies have investigated the association between MBL2 exon 1 polymorphisms (rs1800450, rs1800451, and rs5030737) and TB risk, but yielded inconclusive results. Method We conducted this meta-analysis of 26 eligible case–control studies that included 7952 cases and 9328 controls to identify the strength of association. Odds ratio (OR) and 95% CI were used to evaluate the strength of association. Statistical analyses were performed by using STATA 12.1. Results We found a statistically significant correlation between MBL2 exon 1 polymorphisms and increased TB risk among three models: allele model (O vs A: OR =1.18, 95% CI: 1.01–1.38, Pheterogeneity<0.0001, I2=85.8%), homozygote comparison (OO vs AA: OR =1.49, 95%CI: 1.02–2.18, Pheterogeneity<0.0001, I2=79.1%), dominant model (AO/OO vs AA: OR =1.20, 95% CI: 1.01–1.43, Pheterogeneity<0.0001, I2=83.5%), especially in studies based on Asian populations among five models: allele model (O vs A: OR =1.29, 95% CI: 1.11–1.51, Pheterogeneity<0.0001, I2=66.0%), homozygote comparison (OO vs AA: OR =1.67, 95% CI: 1.09–2.55, Pheterogeneity=0.008, I2=54.2%), heterozygote comparison (AO vs AA: OR =1.26, 95% CI: 1.05–1.50, Pheterogeneity=0.001, I2=62.9%), dominant model (AO/OO vs. AA: OR =1.31, 95% CI: 1.10–1.56, Pheterogeneity=0.001, I2=64.2%), and recessive model (OO vs AO/AA: OR =1.50, 95% CI: 1.01–2.22, Pheterogeneity=0.023, I2=48.0%). Meta-regression results revealed that source of controls (p=0.009), but not ethnicity (p=0.687), genotyping method (p=0.231), and sample size (p=0.451) contributed to the source of heterogeneity. Conclusion This meta-analysis suggests that MBL2 exon 1 polymorphisms may contribute to TB risk, especially in Asian populations.

Abstract
OBJECTIVE Tuberculosis (TB) is caused by infection of Mycobacterium tuberculosis. Host genetic variability is an important determinant of the risk of developing TB in humans. Although the association between MBL polymorphisms and TB has been studied in various populations, the results are controversial. The aim of this study was to investigate mannose-binding lectin (MBL) gene polymorphisms with susceptibility to pulmonary tuberculosis (PTB) in a Lur population of Iran. METHODS In this case-control study, four functional MBL gene polymorphisms (HL, XY, PQ and AB) were genotyped by using PCR Single Strand Conformation Polymorphism (SSCP) technique in a Lur population living in Lorestan Province, consisting of 100 patients with pulmonary tuberculosis (PTB) age and sex matched 100 healthy controls (HCs). Association analyses were performed with the SPSS 21 statistical software. RESULTS We found that MBL (HH) genotype polymorphism significantly was associated with increased susceptibility to TB (35% in patients vs. 22% in controls, P = 0.0417, OR = 1.909, %95 CI = 1.020-3.573). Additionally, H allele showed a significant association with increased risk of TB (56.5% in patients vs. 46% in controls, P = 0.0357, OR = 1.525, %95 CI = 1.028-2.262). Also, the distribution of L allele in patients was significantly lower frequency in TB patients compared to controls (43.5% vs. 54%, P = 0.0357, OR = 0.656, %95 CI = 0.442-0.973). However, the allelic and genotypic frequencies of AB, XY and PQ polymorphisms were not significantly different between the patients and the controls. We couldn't detect any significant differences between haplotypes among TB patients and healthy controls. CONCLUSIONS Our findings demonstrated that HH genotype and H allele may increase the susceptibility to pulmonary TB in the Lur population of Iran, although L allele may decrease the susceptibility to pulmonary TB in this population. We suggest that it is necessary to further more studies with larger sample size and other ethnic population.

Abstract
BACKGROUND Interferon-gamma (IFN-γ) is a key cytokine in defense against mycobacteria, including Bacillus Calmette-Guérin (BCG). Mannose-binding lectin (MBL) and toll-like receptors (TLRs) are pattern-recognizing molecules of innate immunity. The aim of the present study was to investigate the relationship between polymorphisms in MBL, TLR1, TLR2 and TLR6 encoding genes and stimulated IFN-γ and interleukin-12 (IL-12) ex vivo production in BCG osteitis survivors. METHODS Data on single nucleotide polymorphisms in the MBL2 gene and TLR1, TLR2 and TLR6 genes were available from 132 former BCG osteitis patients, and data on ex vivo IFN-γ and IL-12 production were available from 115 and 118 patients, respectively. The present study is a secondary analysis of these available data. In an earlier study, we were able to characterize low IFN-γ and low IL-12 producers after BCG+IL-12 or BCG+IFN-γ stimulations, respectively. RESULTS Three patients had the homozygous variant MBL2 genotype, and one of them was a low IFN-γ producer (both concentration and response <5th percentile). The heterozygous variant MBL2 genotype showed no association with IFN-γ or IL-12 production. The TLR2 variant genotype was present in 14 subjects; 28.6% of them were low IFN-γ producers versus 7.8% of those 103 with the TLR2 wild genotype (P = 0.037). TLR1 or TLR6 polymorphisms had no significant associations with stimulated ex vivo IFN-γ or IL-12 production. CONCLUSIONS Preliminary evidence was found that variant genotypes of the MBL2 gene (if homozygous) and variant genotypes of the TLR2 gene (only heterozygotes present) are associated with low IFN-γ production.

Abstract
MBL2 gene encodes mannose-binding lectin, is a member of innate immune system. Earlier studies revealed that MBL2 gene variants, rs1800451, rs1800450, rs5030737, rs7096206, rs11003125 and rs7095891 are associated with impaired serum level and susceptibility to TB, but their results are inconsistent. A meta-analysis was performed by including 22 studies (7095 TB-patients and 7662 controls) and data were analyzed with respect to associations between alleles, genotypes and minor allele carriers to evaluate the potential association between MBL2 polymorphisms and TB risk. Statistically significant results were found only for the homozygous variant genotype (CC vs. AA: p = 0.045; OR = 0.834, 95% CI = 0.699 to 0.996) of rs1800451 and showed reduced risk of TB in overall population. However, other genetic models of rs1800450, rs5030737, rs7096206, rs11003125, rs7095891 and combined rs1800450, rs1800451, rs5030737 polymorphisms of MBL2 gene did not reveal any association with TB risk. Stratified analysis by ethnicity showed decreased risk of TB in African population for rs1800450 and rs1800451. Whereas, no association was observed between other MBL2 polymorphisms and TB risk in all the evaluated ethnic populations. In conclusion, MBL2 rs1800450 and rs1800451 polymorphisms play a protective role in TB infection and reinforce their critical significance as a potential genetic marker for TB resistance.

Association of Mannose-binding Lectin Polymorphisms with Tuberculosis Susceptibility among Chinese. Sci Rep 2016; 6:36488.

Abstract
Tuberculosis (TB) is caused by infection of Mycobacterium tuberculosis. Host genetic variability is an important determinant of the risk of developing TB in humans. Although the association between MBL2 polymorphisms and TB has been studied in various populations, the results are controversial. In this study four functional single-nucleotide polymorphisms (SNPs, H/L, X/Y, P/Q and A/B) across the MBL2 gene were genotyped by direct DNA sequencing of PCR products in a case-control population of Chinese Han origin, consisting of 1,020 patients with pulmonary TB and 1,020 controls. We found that individuals carrying variant allele at A/B (namely BB or AB genotypes) was associated with increased susceptibility to TB (odds ratios [OR] = 1.57, 95% confidence interval [CI] 1.30–1.91, P = 1.3 × 10−6). Additionally, LYPB haplotype showed a significant association with increased risk of TB (OR = 1.54, 95% CI 1.27–1.87, P = 4.2 × 10−6; global haplotype association P = 3.5 × 10−5). Furthermore, individuals bearing low- or medium- MBL expression haplotype pairs had an increased risk of TB (OR = 1.56, 95% CI 1.29–1.90, P = 1.4 × 10−6). Thus, the reduced expression of functional MBL secondary to having MBL2 variants may partially mediate the increased susceptibility to TB risk.

Abstract
Low mannose binding lectin (MBL) producer genotypes have been considered as a systemic lupus erythematosus (SLE) risk factor. The aim of this study was to explore whether polymorphisms in the MBL gene are associated with susceptibility to SLE and disease-specific clinical manifestations or with disease severity in SLE patients in Son Llàtzer Hospital. MBL2 exon 1 and promoter polymorphisms were genotyped and MBL plasma levels were quantified by ELISA in 39 SLE cases and in 96 healthy controls. High MBL producer genotypes HYPA and LXPA were the most frequent haplotypes (65 and 62 participants, respectively). LYQC/HYPD, LXPA/LYQC and LYPB/HYPD were only found in SLE, and all of them were related to severe MBL deficiency. SLE patients showed a trend towards more severe MBL deficiency (MBL <100 ng/mL) compared to controls (10 [25.6%] and 11 [11.46%] respectively, P = 0.07). The wild-type genotype was more frequent in controls compared to SLE. The trend towards more severe MBL deficiency in SLE and the fact that some of the low-MBL producer genotypes were only found in SLE patients, suggest that low MBL levels or MBL2 variant could be a risk factor for the development of SLE.

Int J Infect Dis 2015; 38:129-35. [PMID: 26261060 DOI: 10.1016/j.ijid.2015.08.003] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2014] [Revised: 05/30/2015] [Accepted: 08/02/2015] [Indexed: 11/27/2022] Open
Abstract
OBJECTIVES To investigate natural-resistance-associated macrophage protein 1 (NRAMP1), mannose-binding lectin (MBL), vitamin D receptor (VDR) gene polymorphisms and their interaction with susceptibility to pulmonary tuberculosis (PTB) in a Chinese population. METHODS A case-control study was conducted in PTB (n=151), age- and sex- matched healthy controls (HCs) (n=453). Genetic polymorphisms of NRAMP1 (INT4, D543NA and 3'UTR), MBL (HL, PQ, XY and AB) and VDR (FokI and Taq) were analyzed by using PCR-restriction fragment length polymorphism (RFLP) and PCR- single- strand conformation polymorphism (SSCP) techniques. Multifactor dimensionality reduction (MDR) analysis was carried out to assess the effects of the interaction between SNPs. RESULTS The distribution of NRAMP1- 3'UTR (TGTG/del), MBL- HL (H/L) and FokI (F/f) were significantly different between PTB patients and HCs (p<0.05). HPYA (OR: 1.88; 95% CI: 1.22-2.91), LPXA (OR: 3.17; 95% CI: 1.69- 5.96), LQYA (OR: 3.52; 95%CI: 1.50-8.23) and LPYB (OR: 12.37; 95%CI: 3.75- 40.85) of MBL were risk haplotypes for PTB. The TGTG- H- f (OR: 1.70; 95%CI: 1.10-2.62) and del- H-f (OR: 3.48; 95% CI: 1.45-8.37) of 3'UTR- HL- FokI were also high-risk haplotypes associated with tuberculosis. CONCLUSIONS Our study suggests that genotypes of many polymorphic genes are associated with TB, it is necessary to further explore the mechanism of genotypes and gene-gene interaction in susceptibility to tuberculosis.
