Abstract
Vitamin D receptor (VDR) is one of the most widely studied genes for the Tuberculosis (TB) susceptibility. Several studies have been conducted to establish some association between them but most of the time they are contradictory and underpowered. So, a trial sequential meta-analysis between VDR gene polymorphisms and TB susceptibility can provide a better understanding of the relationship. A meta-analysis was carried out using a total of 17 case-control studies which includes Fok1 (14 Studies), Bsm1 (8 Studies), Apa1 (8 Studies) and Taq1 (12 Studies) polymorphisms in the VDR gene searched from Pubmed and Google Scholar. Pooled Odds Ratio (OR) and 95% Confidence Interval (CI) were calculated using StatsDirect Version 3, using random effects model. Trial sequential analysis (TSA) was also performed to assess if the statistical significance of the meta-analysis was within monitoring boundaries. It was found that the individuals with BB genotype of Bsm1 polymorphism with OR = 0.713 (95%CI = 0.521, 0.974; p value < 0.05) and FF genotype of Fok1 polymorphism with pooled OR = 0.716 (95%CI = 0.523, 0.979; p value < 0.05) had decreased incidence of TB. Also, the aa genotype of Apa1 gene polymorphism increases susceptibility to TB with pooled OR = 1.997 (95%CI = 1.121, 3.558; p value < 0.05). All these analyses reached the required information size through TSA analysis. No statistically significant result was found for Taq1 polymorphisms and TB susceptibility. VDR polymorphisms in Fok1 and Bsm1 played protective roles against development of TB infection, while Apa1 appeared to have a significant association to TB susceptibility.

Abstract
Background The aim of the present study was to investigate the association between vitamin D receptor (VDR) gene polymorphism and tuberculosis susceptibility, as well as the potential interaction of host genetic factors with the heterogeneity of Mycobacterium tuberculosis in the population from Xinjiang, China. Methods From January 2019 to January 2020, we enrolled 221 tuberculosis patients as the case group and 363 staff with no clinical symptoms as the control group from four designated tuberculosis hospitals in southern Xinjiang, China. The polymorphisms of Fok I, Taq I, Apa I, Bsm I, rs3847987 and rs739837 in the VDR were detected by sequencing. M. tuberculosis isolates were collected from the case group and identified as Beijing or non-Beijing lineage by multiplex PCR. Propensity score (PS), univariate analysis and multivariable logistic regression models were used to perform the analysis. Results Our results showed that the allele and genotype frequencies of Fok I, Taq I, Apa I, Bsm I, rs3847987 and rs739837 in VDR were not correlated with tuberculosis susceptibility or lineages of M. tuberculosis. Two out of six loci of the VDR gene formed one haplotype block, and none of the haplotypes was found to correlate with tuberculosis susceptibility or lineages of M. tuberculosis infected. Conclusion Polymorphisms in the VDR gene may not indicate susceptibility to tuberculosis. There was also no evidence on the interaction between the VDR gene of host and the lineages of M. tuberculosis in the population from Xinjiang, China. Further studies are nonetheless required to prove our conclusions.

Abstract
Tuberculosis (TB) prevalence is increasing in developed nations and continuing to cause significant mortality in low- and middle-income countries. As a result of the uptick in cases, there also exists an increased prevalence of extrapulmonary TB. TB is caused by Mycobacterium tuberculosis (M. tb). When M. tb disseminates to the vertebral column, it is called Pott's disease or spinal TB. The frequency, symptoms, and severity of the disease range by the location of the spine and the region of the affected vertebrae. While the current literature shows that timely diagnosis is crucial to reduce the morbidity and mortality from Pott's disease, there is a lack of specific clinical diagnostic criteria for Pott's disease, and the symptoms may be very non-specific. Studies have shown that novel molecular diagnostic methods are effective and timely choices. Research has implicated the risk factors for the susceptibility and severity of Pott's disease, such as HIV and immunosuppression, poverty, and malnutrition. Based on the current literature available, our group aims to summarize the pathogenesis, clinical features, diagnostic challenges, as well as the known risk factors for Pott's disease within this literature review.

Abstract
INTRODUCTION Tuberculosis (TB) is a transnational public health concern, which requires more precise treatment strategies than the existing approaches. Vitamin D modulates the inflammatory and immune response to the disease. Robust evidence shows that vitamin D deficiency and its receptor gene polymorphism influence the susceptibility to TB and the outcome of the anti-tubercular treatment (ATT). However, in the different populations, these findings were inconsistent and even contradictory. AREAS COVERED The current review focuses on the association between vitamin D receptor (VDR) gene polymorphism with the risk of development of TB disease and response to the ATT. Additionally, it reviews various systematic reviews and meta-analyses on the impact of vitamin D supplements on both clinical and treatment outcomes in TB patients. EXPERT OPINION Although the majority of the findings rule out the benefits of the supplementation, sufficient evidence is available to warrant larger epidemiological research that should be aimed to generate possible interaction among the VDR polymorphism, vitamin D status, and the outcome in TB. We conclude that establishing such an association in different ethnic populations will help design nutrigenomics- or pharmacogenomics-based vitamin D supplementation to develop a personalized medicine approach to flatten the curve of TB disease.

Abstract
OBJECTIVE This study aimed to provide a basis for the diagnosis of spinal TB by analyzing its pathologic characteristics. METHODS The data of 181 patients with spinal TB who underwent surgery from January 2013 to January 2019 at the General Hospital of Ningxia Medical University were retrospectively analyzed. The participants comprised 80 men and 101 women with an average age of 45.1 ± 16.5 (range: 14-78) years. Based on the assessment of tissue samples, five patients had cervical TB, 49 had thoracic TB, 86 had lumbar TB, 22 had thoracolumbar TB, and 19 had lumbosacral TB. Tuberculous granulation tissue, sclerotic bone, sequestrum, and intervertebral disc tissue were collected for hematoxylin and eosin staining. The proportion of patients with atypical and typical pathologic characteristics was identified and compared for statistical analysis. RESULTS The typical pathologic characteristics included tubercles, granulomas, caseous necrosis, multinuclear giant cells, infiltration of acute inflammatory cells, sequestration, and fibroblastic proliferation. A total of 119 patients had caseous necrosis, 95 had multinuclear giant cells, 68 had granulomatous inflammation, and 21 had tubercles. Moreover, 46 (25.4%) patients had at least three pathologic characteristics and only 12 (6.6%) exhibited all the pathologic characteristics. Of the 35 (19.3%) patients with atypical pathologic characteristics, 17 had lymphocyte infiltration, 10 had fibroblastic proliferation, 2 had hyaline changes, 1 had local hemorrhage, 1 chronic inflammatory change, 2 had sequestration, 1 had dilated and congested vessels, and 1 had acute suppurative inflammation. CONCLUSIONS The most common pathologic characteristics were caseous necrosis, multinuclear giant cells, granulomatous inflammation, and tubercles. Moreover, multiple pathologic characteristics were observed in patients with spinal TB and one type of these characteristics was dominant. However, atypical pathologic characteristics were also noted. Thus, both pathologic examination and clinical analysis must be performed to improve the diagnostic rate of spinal TB.

Serum 25-hydroxyvitamin D level and vitamin D receptor (VDR) polymorphisms in patients infected with Leishmania tropica: a case control study. J Parasit Dis 2020; 44:40-48.

Abstract
Leishmania, an obligate intracellular parasite is eliminated by a strong Th-1 host response. As Vitamin D metabolism and its receptor activity are important factors in human native immune system against some microorganisms, we hypothesized that VDR gene polymorphisms and concentration of Vitamin D might have effect on incidence of cutaneous leishmaniasis. The aim of this study was to investigate the association between VDR gene polymorphism and/or the serum vitamin D level and leishmaniasis in the infected patients in comparison to the healthy individuals. In this case-control study, the BsmI, FokI and Taq1 polymorphisms in the VDR gene and serum levels of vitamin D were studied in Iranian infected with Leishmania tropica (n = 50) and healthy controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and Electrochemiluminescence methods respectively. Data were statistically analyzed using SPSS software, Chi square and ANOVA tests. The results of this study showed that despite the relatively higher frequency of BsmI-BB, FokI-FF and TaqI-Tt than Non BsmI-BB, Non FokI-FF and Non TaqI-Tt in the patients compared with the healthy individuals, the differences were not statistically significant (P > 0.05). Based on our findings, the relationship between the VDR polymorphism, the serum concentration of 25-hydroxyvitamin D and the susceptibility to Leishmania tropica infection, remains unclear requiring further in-depth studies. However, for better interpretation, it is necessary to consider factors such as the size of the sample examined and the other alleles of VDR, including ApaI.

Abstract
BACKGROUND Independent of HIV infection, extrapulmonary TB (EPTB) risk is increased in women, persons of black race or foreign birth, and by genetic variants in vitamin D receptor (VDR), interleukin-1 beta (IL-1β), and toll-like receptor (TLR)-2; functional correlates are unclear. We evaluated macrophage expression of VDR, TLR2, cathelicidin, and TNF-α, and production of IL-1β in HIV-seronegative persons with previous EPTB, previous pulmonary TB, latent M. tuberculosis infection, and uninfected TB contacts. Persons with previous pleural TB were excluded due to enhanced immune responses at the site of disease. METHODS Macrophages were stimulated with TLR-2 agonist M. tuberculosis lipoprotein (LpqH), live and gamma-irradiated M. tuberculosis. RESULTS M. tuberculosis - infected macrophages from persons with previous EPTB had increased VDR expression (29.17 relative value unit increase in median expression vs. uninfected contacts, after adjusting for foreign-born status; P = 0.02). Macrophages from persons with previous EPTB had a 38.88 μg/mL increase in median IL-1β production after stimulation with LpqH compared to uninfected contacts (P = 0.01); the effect was similar (44.99 μg/mL) but not statistically significant after controlling for foreign-born status. Median 25-hydroxyvitamin D levels were low but not significantly different between groups. CONCLUSIONS There was increased macrophage expression of VDR after stimulation with live M. tuberculosis in persons with previous extrapulmonary TB. If post-treatment VDR expression reflects expression prior to disease, it may identify persons at risk for extrapulmonary TB.

Abstract
We performed a meta-analysis to evaluate potential associations between
vitamin D receptor (VDR) genetic variants and
tuberculosis (TB). Systematic literature research was conducted in
PubMed, Web of Science, and Embase. We calculated odds ratios (ORs)
and 95% confidence intervals (CIs) to estimate strength of
associations in all possible genetic models, and P
values ≤ 0.05 were considered to be statistically significant. In
total, 42 studies were enrolled for analyses. Pooled overall analyses
suggested that VDR rs1544410 (dominant model:
P = 0.02; allele model:
P = 0.03) and rs731236 (dominant model:
P = 0.04; recessive model:
P = 0.02; allele model: P = 0.01)
variants were significantly associated with TB. Further subgroup
analyses by ethnicity revealed that rs1544410 (dominant and allele
models) and rs731236 (dominant, recessive, and allele models) variants
were both significantly associated with TB in South Asians. When we
stratified data by type of disease, positive results were detected for
rs7975232 variant in EPTB (dominant, recessive, over-dominant, and
allele models) subgroup, and for rs2228570 variant in PTB (dominant,
recessive, and allele models) and EPTB (dominant, recessive,
over-dominant, and allele models) subgroups. Our meta-analysis
supported that rs7975232, rs1544410, rs2228570, and rs731236 variants
might serve as genetic biomarkers of certain types of TB.

Abstract
Objective To date, a series of studies were conducted to investigate the association between TLR2 (Toll-like receptor 2) Arg753Gln gene polymorphism and tuberculosis (TB). However, the results were inconsistent. This meta-analysis was performed to elucidate the roles of TLR2 Arg753Gln gene polymorphism in TB. Methods All available articles were searched from online databases such as PubMed, Medline, CNKI, and Wanfang. Statistical analyses were performed using the STATA12.0 (Stata Corp LP, College Station, TX, United States) software. Results 32 case-control studies comprising 5943 cases and 5991 controls were identified in this meta-analysis. Overall, the TLR2 Arg753Gln gene polymorphism was associated with high TB risk in allele model (A vs. G: OR=2.20, 95%CI=1.60-3.04, P≤0.01), dominant model (AA+AG vs. GG: OR=2.70, 95%CI=2.00-3.65, P≤0.01), and heterozygote model (AG vs. GG contrast: OR=2.97, 95%CI=2.39-3.69, P≤0.01). Subgroup analysis by ethnicity indicated that the A allele increased susceptibility to TB in Asian (OR=3.35, 95%CI=2.36-4.74) and Caucasian populations (OR=2.62, 95%CI=1.77-3.87), but not in African (2.08, 95%CI=0.62-2.72) or mixed populations (OR=0.76, 95%CI=0.36-1.14). Stratified analysis by sample type suggested that the A allele associated with high pulmonary tuberculosis (PTB) risks (OR=2.43, 95%CI=1.66-3.54), but not with extra pulmonary tuberculosis (EPTB) (OR=1.84, 95%CI=0.83-4.06). Conclusion this meta-analysis suggested the following: (1) TLR2 Arg753Gln polymorphism is significantly associated with high TB risk. (2) In subgroup analysis based on ethnicity, TLR2 Arg753Gln polymorphism elevates the risk of TB in Asian and Caucasian populations, but not in African or mixed populations. (3) Stratified by sample type, TLR2 Arg753Gln polymorphism is associated with increased PTB risk, but not with EPTB.

Objective: The present study investigated the clinical significance of mannose-binding lectin 2 (MBL2), cluster of differentiation 14 (CD14) and tumour necrosis factor-α (TNF-α) gene polymorphisms in patients with spinal tuberculosis (TB) in Chinese population. Methods: A total of 240 patients with spinal TB were enrolled in the present study from May 2013 to August 2016 at Hangzhou Red Cross Hospital. A total of 150 age- and sex-matched healthy subjects were enrolled as controls. The genomic DNA was extracted from the peripheral blood of all subjects, and the MBL2, CD14 and TNF-α gene polymorphisms were detected by direct DNA sequencing. Results: (1) Compared with controls, patients with spinal TB exhibited a significantly higher frequency of the XY genotype at the −221G>C polymorphism as well as the Q allele and PQ genotype or an association with the QQ genotype at the +4C>T polymorphism in the MBL2 gene. (2) Compared with controls, patients with spinal TB exhibited a significantly higher frequency of the T allele and TT genotype or an association with the CT genotype at the −159C>T polymorphism in the CD14 gene. (3) Compared with controls, patients with spinal TB exhibited a significantly higher frequency of the T allele and the CT genotype or an association with the TT genotype at the TNF-857 polymorphism in the TNF-α gene. Conclusion: The −221G>C polymorphism of MBL2, the −159C>T polymorphism of CD14 and the TNF-857 polymorphism of TNF-α are risk factors for spinal TB and may be involved in the development of spinal TB in the Chinese population. These factors are indicators of susceptibility to spinal TB and require clinical attention.

Abstract
Purpose of review Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB), remains a major public health threat globally. Several lines of evidence support a role for host genetic factors in resistance/susceptibility to TB disease and MTB infection. However, results across candidate gene and genome-wide association studies (GWAS) are largely inconsistent, so a cohesive genetic model underlying TB risk has not emerged. Recent Findings Despite the difficulties in identifying consistent genetic associations, genetic studies of TB and MTB infection have revealed a few well-documented loci. These well validated genes are presented in this review, but there remains a large gap in how these genes translate into better understanding of TB. To address this, we present a pathway based extension of standard association analyses, seeding the results with the best validated genes from candidate gene and GWAS studies. Summary Several pathways were significantly enriched using pathway analyses that may help to explain population patterns of TB risk. In conclusion, we advocate for novel approaches to the study of host genetic analysis of TB that extend traditional association approaches.

Abstract
OBJECTIVE To investigate the association between vitamin D receptor (VDR) gene Apa I polymorphism and the susceptibility to bone and joint tuberculosis in Chinese Han population. METHODS Between May, 2015 and June, 2016, 100 patients with bone and joint tuberculosis and 100 healthy volunteers were recruited concomitantly in Heyuan Hospital of Traditional Chinese Medicine. Vitamin D receptor gene Apa I polymorphisms in these subjects were analyzed using SNaPshot. RESULT The genotype frequencies of Apa I-AA, Apa I-Aa and Apa I-aa were 51%, 41%, and 8% in the case group and 33%, 55%, and 12% in the control group, respectively, showing significant differences between the two groups (P<0.05). The genotype of Apa I-AA was significantly higher in the case group with an odds ratio (OR) of 2.073 (95% CI: 1.142-3.763). CONCLUSION The Apa I polymorphisms of the VDR gene are associated with the susceptibility to bone and joint tuberculosis in Chinese Han population, and individuals with a Apa I-AA genotype are at greater risks to develop bone and joint tuberculosis.
