Mi J, Wu X, Liang J. The advances in adjuvant therapy for tuberculosis with immunoregulatory compounds. Front Microbiol 2024; 15:1380848. [PMID: 38966394 PMCID: PMC11222340 DOI: 10.3389/fmicb.2024.1380848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Accepted: 06/10/2024] [Indexed: 07/06/2024] Open
Abstract
Tuberculosis (TB) is a chronic bacterial disease, as well as a complex immune disease. The occurrence, development, and prognosis of TB are not only related to the pathogenicity of Mycobacterium tuberculosis (Mtb), but also related to the patient's own immune state. The research and development of immunotherapy drugs can effectively regulate the body's anti-TB immune responses, inhibit or eliminate Mtb, alleviate pathological damage, and facilitate rehabilitation. This paper reviews the research progress of immunotherapeutic compounds for TB, including immunoregulatory compounds and repurposing drugs, and points out the existing problems and future research directions, which lays the foundation for studying new agents for host-directed therapies of TB.

Mutational Dynamics Related to Antibiotic Resistance in M. tuberculosis Isolates from Serial Samples of Patients with Tuberculosis and Type 2 Diabetes Mellitus. Microorganisms 2024; 12:324. [PMID: 38399727 PMCID: PMC10892438 DOI: 10.3390/microorganisms12020324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/05/2024] [Accepted: 01/10/2024] [Indexed: 02/25/2024] Open
Abstract
Genetic variation in tuberculosis is influenced by the host environment, patients with comorbidity, and tuberculosis-type 2 diabetes mellitus (TB-T2DM) and implies a higher risk of treatment failure and development of drug resistance. Considering the above, this study aimed to evaluate the influence of T2DM on the dynamic of polymorphisms related to antibiotic resistance in TB. Fifty individuals with TB-T2DM and TB were initially characterized, and serial isolates of 29 of these individuals were recovered on day 0 (diagnosis), 30, and 60. Genomes were sequenced, variants related to phylogeny and drug resistance analyzed, and mutation rates calculated and compared between groups. Lineage X was predominant. At day 0 (collection), almost all isolates from the TB group were sensitive, apart from four isolates from the TB-T2DM group showing the mutation katG S315T, from which one isolate had the mutations rpoB S450L, gyrA A90G, and gyrA D94G. This pattern was observed in a second isolate at day 30. The results provide a first overview of the dynamics of mutations in resistance genes from individuals with TB-T2DM, describing an early development of resistance to isoniazid and a rapid evolution of resistance to other drugs. Although preliminary, these results help to explain the increased risk of drug resistance in individuals with TB and T2DM.

Abstract
Genes related to DNA damage repair in Mycobacterium tuberculosis are critical for survival and genomic diversification. The aim of this study is to compare the presence of SNPs in genes related to DNA damage repair in sensitive and drug-resistant M. tuberculosis genomes isolated from patients with and without type 2 diabetes mellitus (T2DM). We collected 399 M. tuberculosis L4 genomes from several public repositories; 224 genomes belonging to hosts without T2DM, of which 123 (54.9%) had drug sensitive tuberculosis (TB) and 101 (45.1%) had drug resistance (DR)-TB; and 175 genomes from individuals with T2DM, of which 100 (57.1%) had drug sensitive TB and 75 (42.9%) had DR-TB. The presence of SNPs in the coding regions of 65 genes related to DNA damage repair was analyzed and compared with the resistance profile and the presence/absence of T2DM in the host. The results show the phylogenetic relationships of some SNPS and L4 sub-lineages, as well as differences in the distribution of SNPs present in DNA damage repair-related genes related to the resistance profile of the infecting strain and the presence of T2DM in the host. Given these differences, it was possible to generate two discriminant functions to distinguish between drug sensitive and drug resistant genomes, as well as patients with or without T2DM.

Abstract
Objectives Mortality from tuberculosis (TB) has been declining since 2000, nevertheless there is still a significant number of patients who die before or during TB treatment. The aims were to examine and describe predictors associated with TB related mortality. Methods Patients notified with TB from 2009 though 2014 in Denmark were included. Data were extracted from national registers and patient records were examined for clinical information and treatment outcome. Cox proportional hazards regression was used to examine TB related mortality. Results A total of 2131 cases were identified, 141 (6.6%) patients died before or during TB treatment. TB related mortality accounted for 104 cases (73.8%) and decreased significantly from 6.7% to 3.2% (p = .04) during the study period. Within 1 months of diagnosis, 49% of TB related deaths had occurred. The strongest risk factors present at time of diagnosis, associated with TB related mortality, were: age > 70 years, Charlson comorbidity index > 1, alcohol abuse, weight loss, anemia, and C-reactive protein > 100 mg/L (p < .05). Conclusion The majority of TB related deaths occurred soon after diagnosis, emphasizing that TB patients identified to have a high risk of mortality should be closely monitored before and during the intensive treatment period to improve their outcomes.

The Mouse Bile Duct Tapeworm, Hymenolepis Microstoma in Free-living Small Mammals in Slovakia: Occurrence and Genetic Analysis. Helminthologia 2020; 57:120-128.

Abstract
The mouse bile duct tapeworm Hymenolepis microstoma, is a potentially zoonotic species with a wide variety of reported definitive hosts of rodent genera. In the present study the occurrence of H. microstoma in free-living small mammals in selected areas of Slovakia and the retrospective analysis of epidemiological data published in Slovakia were performed. Hymenolepis microstoma was detected in two animal species, the common shrew (Sorex araneus) and the European hamster (Cricetus cricetus) of 186 small mammals examined from two ecosystems, urban and natural ecosystem of national park. No mention about the presence of this parasite in Slovakia in the past was found following a bibliographical search. Partial sequences of the nuclear paramyosin gene showed the shrew isolate placed in a subclade together with H. microstoma from Portugal, with high bootstrap value for its differentiation from the sister species Hymenolepis nana. Similarly, the analysis of the nuclear ribosomal ITS region placed the hamster isolate in the cluster composed of H. microstoma from Australia, Spain and Portugal. The Slovak isolate was the most distinctive sample among available H. microstoma, differing in 1.4 - 1.9% of nucleotides from the remaining isolates. The difference (seven of 17 nucleotide positions) was partially due to indel polymorphisms associated with two and five nucleotides. To our knowledge, these are the first reports of H. microstoma in Central Europe and also the first record of infection in the common shrew. A recently indicated zoonotic potential of H. microstoma along with a possibility of its direct transmission between animals and/or humans without the need of intermediate hosts pose a public health concern in contaminated areas of Slovakia. The use of molecular techniques may substantially facilitate more thorough understanding of the epidemiological situation of H. microstoma and related tapeworms in various ecosystems of the country.

Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb) infection, remains a major global health emergency. It is estimated that one third of global population are affected, predominantly with latent granuloma form of the disease. Mtb co-evolved with humans, for its obligatory intra-macrophage phagosome habitat and slow replication, balanced against unique mycobacterial innate immunity, which appears to be highly complex. TB is transmitted via cough aerosol Mtb inhalation. Bovine TB attenuated Bacillus Calmette Guerin (BCG) live vaccine has been in practice for protection of young children from severe disseminated Mtb infection, but not sufficiently for their lungs, as obtained by trials in TB endemic community. To augment BCG vaccine-driven innate and adaptive immunity for neonates and better protection against adult pulmonary TB, a number of BCG pre-vaccination based, subset vaccine candidates have been tested via animal preclinical, followed by safe clinical trials. BCG also enhances innate macrophage trained immunity and memory, through primordial intracellular Toll-like receptors (TLRs) 7 and 9, which recognise distinct mycobacterial molecular pattern signature. This signature is transmitted by TLR signalling via nuclear factor-κB, for activating innate immune transcription and expression of gene profiling in a mycobacterial signature-specific manner. These are epigenetically imprinted in reprogramming of distinct chromatin areas for innate immune memory, to be recalled following lung reinfection. Unique TB innate immunity and its trained memory are considered independent from adaptive immune B and T cells. On the other hand, adaptive immunity is crucial in Mtb containment in granulomatous latency, supported by innate immune cell infiltration. In nearly 5-10 % of susceptible people, latent TB may be activated due to immune evasion by Mtb from intracellular phagosome within macrophage, perpetrating TB. However, BCG and new recombinant BCG vaccines have the capacity, as indicated in pre- and clinical trials, to overcome such Mtb evasion. Various strategies include pro-inflammatory-bactericidal type 1 polarisation (M1) phenotype of the infected macrophage, involving thrombospondin-TLR pathway. Saprophytic M. smegmatis-based recombinant vaccines are also promising candidates against TB. BCG vaccination of neonates/infants in TB endemic countries also reduced their pneumonia caused by various microbes independent of TB immunity. Here, we discuss host immune response against Mtb, its immune evasion strategies, and the important role innate immunity plays in the development of protection against TB.

Abstract
The treatment options for acute stroke combined with pulmonary infection are limited. Clinically, there are several therapies to promote blood circulation and dissipate blood stasis; these treatment options include ginkgolide B (GB), which has PAF (platelet activating factor)-inhibiting effects. PAF-receptor (PAF-R) antagonists are used to treat a variety of inflammatory diseases; however, the potential of PAF-R antagonists as a treatment for lung infections remains unclear. The aim of the present study is to investigate the protective effect of GB on lipopolysaccharide-induced inflammatory responses in A549 human pulmonary alveolar epithelial cells (HPAEpiC) in vitro. Cell viability and apoptosis were measured by CCK-8 and flow cytometry. TRIM37, Caspase-3, and NF-κBp65 expression levels were measured by real-time PCR and Western blotting. The release of tumor necrosis factor-α and interleukin-1β was measured by ELISA. The data indicates that GB may reduce TRIM37 expression by antagonizing the PAF-R pathway, thereby inhibiting the activation of nuclear factor-κB and alleviating the inflammatory response of alveolar epithelial cells. This study is the first to provide insight into the therapeutic potential of GB and suggests that clinical application of GB in acute stroke combined with pulmonary inflammation may be efficacious.

Abstract
Two global epidemics, diabetes mellitus (DM) and tuberculosis (TB), have converged making their control even more challenging. We herein have reviewed metformin's (MTF) effect on patients with active and latent TB, as well as discussed its newly discovered biological mechanisms in mycobacteria. Mounting evidence suggests that MTF provides better outcomes in TB patients, especially those with DM. The mechanisms by which MTF produces its benefits are multiple. Though metformin's potential has been proven in patients with DM, larger and more thorough clinical trials, in DM and non-DM-TB patients, need to be conducted. MTF could be added to the arsenal of anti-TB drugs, aiding in the goal of TB eradication worldwide.

Abstract
Background Dosages of anti-tuberculosis (TB) drugs are recommended to be adjusted according to renal function for patients complicated with chronic kidney disease (CKD). However, the efficacy and safety outcomes of such renal function-based dosage adjustments are not fully elucidated. Methods We retrospectively reviewed cases of pulmonary TB susceptible to first-line drugs that were treated at Jikei University Daisan Hospital between 2005 and 2014 with standard regimens based on dosage adjustments according to renal function recommended by international guidelines. Patients were divided into four groups, those with no, mild, moderate or severe CKD. In-hospital TB-related mortality, the rate of sputum culture conversion at 2 months, the frequency of adverse events (AEs), for which at least the temporal discontinuation of the suspect drug was required for patient improvement, and the rate of regimen change due to AEs were assessed. Results In the 241 enrolled patients (mean age, 64.1 years; 143 men), fourteen patients (5.8%) died due to TB during their hospitalization. The rate of sputum culture conversion at 2 months was 78.0%. The frequency of in-hospital TB-related death and the conversion rate in the groups did not vary significantly according to CKD severity including those in the non-CKD group (P = 0.310 and P = 0.864). Meanwhile, a total of 70 AEs were observed in 60 patients (24.9%) and the difference between the groups in the overall frequency of AEs was almost significant (P = 0.051). Moreover, for the 154 patients with CKD, severe CKD stage was a significant risk factor for regimen change (OR = 5.92, 95% CI = 1.08–32.5, P = 0.041), as were drug-induced hepatitis and cutaneous reaction (OR = 35.6, 95% CI = 8.70–145, P < 0.001; OR = 17.4, 95% CI = 3.16–95.5, P = 0.001; respectively). Conclusions Adjusting the dosage of TB treatment for CKD patients according to the guidelines was efficient in terms of similar therapeutic outcome to that of the non-CKD group. However, AEs warrant attention to avoid regimen change in patients with severe CKD, even if the renal function-based dosage adjustment is performed.

Abstract
This study aimed to characterize the cases of tuberculosis (TB) co-infected with
the human immunodeficiency virus (HIV) in Minas Gerais State, Brazil, after the
notification sheet modification, and to verify the association between the new
variables and the treatment outcome. It is an analytical cross-sectional study
with TB/HIV cases notified in the year 2016 to the Brazilian Information System
for Notifiable Diseases (Sistema de Informação de Agravos de
Notificação). Descriptive statistics, chi-square test, and multiple
correspondence analysis were performed to verify the association between the
outcome, ageand associated diseases. Of the 180 cases, most were male (75.6%)
between 30 and 49 years old (63.3%), mixed ethnicity (black and white) (49.4%),
94.4% had the Acquired Immunodeficiency Syndrome (AIDS) and 60.6% had pulmonary
TB. The molecular test was not performed at the time of diagnosis in 70.5% of
the cases. Homeless people (4.4%) and prisoners (3.9%) featured prominently
among the special populations. People between 40 and 49 years old without
concurrent diseases were cured in 40.0% of the cases; 18.9% abandoned the
treatment due to smoking, drug abuse and mental illness in the age group between
20 and 29 years old. The deaths were associated with the age group between 30
and 39 years old and the occurrence of AIDS. The results have shown that the
groups considered vulnerable (drug users, smokers and people with mental
illness) abandoned the treatment, the notification upon death from AIDS in
adults was late and some treatments were inadequate. The epidemiological
surveillance, prevention and assistance strategies towards cases of TB/HIV must
be improved in order to achieve the goal of the Brazilian National Plan to end
Tuberculosis as a Public Health Problem until 2035 in the state.

Abstract
BACKGROUND Lithuania remains one of the highest tuberculosis burden countries in Europe. Epidemiological studies have long pointed to infections as important factors of cancer aetiology, but the association between tuberculosis and the risk of non-pulmonary cancers has rarely been tested and results have been inconsistent. The aim of this population-based cohort study was to examine the risk of cancer among patients diagnosed with tuberculosis using data from Lithuanian Tuberculosis, Cancer and Resident's Registries. METHODS The study cohort included 21,986 tuberculosis patients yielding 1583 cancers diagnosed during follow-up (1998-2012). Standardized incidence ratios (SIRs) and 95% confidence intervals (95% CIs) were calculated to compare the incidence of cancer among cohort participants with the general population for overall, non-pulmonary, site-specific cancers, as well as for subgroups of smoking-related, alcohol-related, hormone-related and haematological cancers. RESULTS The SIRs of all cancers combined were 1.89, 95% CI: 1.79-2.00 in men and 1.34, 95% CI: 1.19-1.50 in women. Risk was increased 3-fold within the first year following diagnosis; it decreased during later years, although remained significantly elevated for ≥5 years. Elevated long-term increased risks persisted for non-pulmonary cancers overall, and for cancers of mouth and pharynx, oesophagus, stomach, larynx, cervix uteri and leukaemias. Tuberculosis was associated with a decreased risk of melanoma. Increased risks were observed for smoking-related cancers in men (SIR 1.95, 95% CI: 1.79-2.13) and women (SIR 1.46, 95% CI: 1.22-1.73), alcohol-related cancers in men (SIR 2.40; 95% CI: 2.14-2.68) and haematological cancers in men (SIR 1.73, 95% CI: 1.33-2.23). The risk of hormone-related cancers was 18% lower (SIR = 0.82, 95% CI: 0.66-0.997) among women, the inverse association was weaker among men (SIR = 0.95, 95% CI: 0.84-1.07). CONCLUSIONS The risk of total and several non-pulmonary cancers was elevated in a cohort of tuberculosis patients. The recommendation for the awareness of this association among physicians is warranted. Analysis suggests a reduction in risk of hormone-related cancers and melanoma.

Abstract
The anomalous distribution of adhesive proteins throughout on the cell surface of the Mycobacterium tuberculosis H37 Rv and their contribution in cell surface adhesion and host-pathogen interaction remain elusive. The completion of M. tuberculosis H37 Rv genome sequence analysis gives some interesting information about polymorphic GC-rich repetitive sequence (PGRS) subfamily of M. tuberculosis that encodes fibronectin binding proteins (FnBP), which have been extensively studied, but the function in the pathogenesis of most of these proteins remains unknown and unclear. This review addresses the M. tuberculosis entry mechanism in the host cell. In particular, an effort has been made to focus on several aspects, (a) association of FnBP encodes by PE_PGRS protein family of M. tuberculosis during host-pathogen interactions. (b) Effect of calcium ions in and outside of the host cell is overriding to maintenance of calcium trafficking in phagocytosis. Furthermore, FnBP may be a potential source of antigenic variation that participating in evoking immune response. M. tuberculosis entry mechanism does not have a major influence alone, involvement of calcium ions, perhaps shed light on host-pathogen interaction relationship, and could open up new avenues for development of novel drug by targeting M. tuberculosis FnBP and blockade of selective adhesions could be useful for therapeutics.

Abstract
Tuberculosis (TB) still remains the thorn in the flesh of efficient therapeutics affecting one-third of global population annually. There are several factors that enhance the susceptibility to TB infections including malnutrition, smoking, and immunocompromised conditions such as AIDS. In the recent years, growing body of evidence has gained considerable prominence which suggests that Diabetes Mellitus (DM) is individual risk factor leading to complicated TB infections. In this article the authors have attempted to summarize the link of type 2 DM with TB, the mechanistic action of how DM sensitizes for developing the active TB infection from the latent infection, and problems faced during treatment followed by possible preventive measures. We have tried to give account of the alterations that occurred in DM making a person more prone to develop TB.

Abstract
The host-pathogen interaction and involvement of calcium (Ca2+) signaling in tuberculosis infection is crucial and plays a significant role in pathogenesis. Ca2+ is known as a ubiquitous second messenger that could control multiple processes and is included in cellular activities like division, motility, stress response, and signaling. However, Ca2+ is thought to be a regulative molecule in terms of TB infection but its binding relation with proteins/substrates molecules which are influenced with Ca2+ concentrations in host-pathogen interaction requires attention. So, in this review, our primary goal is to focus on some Ca2+ substrates/proteins and their imperative involvement in pathogenesis, which is unclear. We have discussed several Ca2+-binding substrate and protein that affect intracellular mechanism of infected host cell. The major involvement of these proteins/substrates including calmodulin (CaM), calpain, annexin, surfactant protein A (SP-A), surfactant protein D (SP-D), calprotectin (MRP8/14), and PE_PGRS family protein are considered to be significant; however, their detailed understanding in mycobacterium infection is limited. In this aspect, this study will help in adding up our understanding in TB biology and additionally in the development of new therapeutic approach to reduce TB pandemic worldwide.

Abstract
Our understanding of bacterial pathogenesis is dominated by the cell biology of the host-pathogen interaction. However, the majority of metabolites that are used in prokaryotic and eukaryotic physiology and signalling are chemically similar or identical. Therefore, the metabolic crosstalk between pathogens and host cells may be as important as the interactions between bacterial effector proteins and their host targets. In this Review we focus on host-pathogen interactions at the metabolic level: chemical signalling events that enable pathogens to sense anatomical location and the local physiology of the host; microbial metabolic pathways that are dedicated to circumvent host immune mechanisms; and a few metabolites as central points of competition between the host and bacterial pathogens.

Abstract
The binding of pathogenic bacteria to extracellular matrix components enhances adhesion and invasion of host cells. The host receptor proteins such as fibronectin (Fn) targeted to pathogenic ligands that have clinical importance. In the present study, we cloned, expressed, purified, and identified a novel Fn-binding protein from PE_PGRS60 (Rv3652) of Mycobacterium tuberculosis H37 Rv. The protein product of Rv3652 showed optimum binding efficiency to 10 ng Fn at 0.2 µg purified protein of PE_PGRS60 and 20 ng Fn at 0.2 µg concentrations, respectively. PE_PGRS60 protein (primary sequences) of different pathogenic mycobacterium species retrieved from NCBI exhibited complete homology at the 104 residues on multiple sequence alignment. The primary sequence of protein from H37 Rv was further used to predict cleavage signals. The secondary structure prediction method revealed a number of residues responsible for alpha helices formation and percentage of residues participating in the random coils and extended strands. In addition, online prediction tools such as B- and T-cell epitopes showed the surface probability scale and antigenic propensity scale. The current finding opens new opportunity to mycobacterial survival and pathogenesis research of PE-polymorphic GC-rich repetitive sequences (PE-PGRS) family proteins.
