BACKGROUND: Interleukin 2 (IL-2) is a cytokine secreted by activated T cells. Studies exploring recombinant human interleukin 2 (rhuIL-2) as an adjunctive immunotherapeutic agent to treat tuberculosis (TB) have shown variable results; however, the true therapeutic efficacy of rhuIL-2 administration in TB patients has not been determined. METHODS: A systematic review to identify publications exploring the association between rhuIL-2-based immunotherapy for TB and outcomes (sputum culture conversion, sputum smear conversion, radiographic changes, and leukocyte phenotype changes) in patients with pulmonary TB published before June 8, 2018 was performed...

When they do not meet norms related to sexuality and reproduction, Bangladeshi women often face abandonment and are thus deprived of an active sexual life, a marital relationship, and motherhood. Little is known about how a stigmatised disease such as tuberculosis (TB) may constrain the reproductive health and sexual lives of women. This article, derived from a larger study on the impact of TB on women's sexual and reproductive health and rights in Narsingdi district and Dhaka, Bangladesh, aims to fill this gap...

The emergence of multidrug resistant-tuberculosis (MDR-TB), defined as Mycobacterium tuberculosis strains with in vitro resistance to at least isoniazid and rifampicin, has necessitated evaluation and validation of appropriate surrogate endpoints for treatment response in drug trials for MDR-TB. The trial that has demonstrated efficacy of bedaquiline, a diarylquinoline that inhibits mycobacterial ATP synthase, possesses the requisite features to conduct this evaluation. Approval of bedaquiline for use in MDR-TB was based primarily on the results of the controlled C208 Stage II study (ClinicalTrials...

BACKGROUND: Contact investigation is an important strategy for maintaining control of tuberculosis (TB) in the United States. However, testing and treatment outcomes specifically to foreign-born populations are poorly understood. We reviewed literature on testing and LTBI identified during contact investigations in foreign-born populations living in the US. METHODS: We conducted a comprehensive search of peer-reviewed and grey literature using Cochrane systematic review methods...

BACKGROUND: Tuberculosis (TB) represents the ninth leading cause of death worldwide. In 2016 are estimated 1.3 million TB deaths among HIV negative people and an additional 374,000 deaths among HIV positive people. In 2016 are estimated 1.4 million new cases of TB in people living with HIV (PLHIV), 74% of whom were living in Africa. In light of these data, the reduction of mortality caused by TB in PLHIV is strongly required specially in low-income countries as Mozambique. According to international guidelines, the initial TB screening in HIV+ patients should be done with the four symptoms screening (4SS: fever, current cough, night sweats and weight loss)...

Mycobacteriophage D29 is a lytic phage that infects various species of Mycobacterium including M. tuberculosis. Its genome has 77 genes distributed almost evenly between two converging operons designated as left and right. Transcription of the phage genome is negatively regulated by multiple copies of an operator-like element known as stoperator that acts by binding the phage repressor Gp71. The function of the D29 genes and their expression status are poorly understood and therefore we undertook a transcriptome analysis approach to address these issues...

Nitazoxanide has antiparasitic and antibiotic activities including activity against Mycobacterium tuberculosis . We prepared and evaluated a set of its analogues to determine the structure-activity relationship, and identified several amide- and urea-based analogues with low micromolar activity against M. tuberculosis in vitro. Pharmacokinetics in the rat suggested a path forward to obtain bioavailable compounds. The series had a good microbiological profile with bactericidal activity in vitro against replicating and nonreplicating M...

A synthetic molecule S006-830, belonging to the class of thiophene-containing trisubstituted methanes, had shown good in vitro and in vivo bactericidal activity against drug-sensitive and drug-resistant Mycobacterium tuberculosis (Mtb). The molecule had also shown good druglike pharmacokinetic properties. However, S006-830 is a racemic mixture of two enantiomers, one of which could possess a better pharmacological profile than the other. We purified both the enantiomers on a chiral column and observed that S-enantiomer has a significantly higher inhibitory and cidal activity against Mtb than the R-enantiomer...

Introduction: Tuberculosis (TB) is one of the endemic diseases with a challenging diagnosis in the absence of pulmonary disease. On the other hand, rheumatoid arthritis (RA) is a systemic autoimmune disease with extra-articular manifestations that occur at any age after onset, such as nodules, Sjögren's syndrome, anemia of chronic disease, and pulmonary manifestations, which are more frequently seen in patients with severe, active disease. Here we present a case of RA with intestinal TB...

REVIEW
Durga Prasanna Misra, Aman Sharma, Vikas Agarwal
The practice of rheumatology in a country like India presents its own unique challenges, including the need to manage patients in a cost-constrained setting, where the lack of uniform government funding for healthcare merits the need to optimize the use of cheaper medicines, as well as devise innovative strategies to minimize the use of costlier drugs such as biologic disease-modifying agents. Use of immunosuppressive agents is also associated with increased risks of infectious complications, such as the reactivation of tuberculosis...

SUMMARYTuberculosis (TB) is the leading infectious cause of mortality worldwide, due in part to a limited understanding of its clinical pathogenic spectrum of infection and disease. Historically, scientific research, diagnostic testing, and drug treatment have focused on addressing one of two disease states: latent TB infection or active TB disease. Recent research has clearly demonstrated that human TB infection, from latent infection to active disease, exists within a continuous spectrum of metabolic bacterial activity and antagonistic immunological responses...

The molecular mechanisms of pathogen persistence within host cells are emerging hotspots, and one of the causes of its persistence is the acid resistance of bacteria. Currently, tuberculosis remains a serious threat to global public health and it is caused by Mycobacterium tuberculosis. In particular, acid resistance of M. tuberculosis and its persistence within macrophages contribute significantly to tuberculosis. Investigations have uncovered three major mechanisms underlying its acid resistance: the control of proton entry, metabolic regulation of intracellular acid-base balance and regulation of the two-component signaling system...

Mycobacterium bovis, the causative agent of bovine tuberculosis encodes different virulence mechanisms to survive inside of host cells. One of the possible outcomes in this host-pathogen interaction is cell death. Previous results from our group showed that M. bovis induces a caspase-independent apoptosis in bovine macrophages with the possible participation of apoptosis inducing factor mitochondria associated 1 (AIFM1/AIF), a flavoprotein that functions as a cell-death regulator. However, contribution of other caspase-independent cell death mediators in M...

Couples HIV testing for tuberculosis (TB) patients and their partners may be an effective means to identify HIV-positive persons and strengthen linkage to HIV care. We evaluated an intervention to increase HIV testing and linkage to care (LTC) of newly diagnosed persons and re-linkage for TB/HIV patients in Pwani, Tanzania. In 2014, 12 TB settings within two regional clusters participated; each cluster included ≥1 referral hospital, health center, and directly observed therapy center. Three months after introducing tools to record HIV service delivery, TB clinic staff and peer education volunteers in Cluster 1 received training on HIV partner testing and linkage/re-linkage, and staff in the second cluster received training 3 months thereafter...
