There is growing interest in the interaction between type 2 diabetes (DM) and tuberculosis (TB), but many research questions remain unanswered. Epidemiologists, basic scientists and clinical experts recently convened and identified priorities. This is the first of two reviews on this topic, summarising priority areas of research with regard to epidemiology, clinical management and public health. First, from an epidemiological point of view, more study is needed to determine the importance of transient hyperglycemia in TB patients, and on the importance of DM for the global epidemic of multi-drug resistant (MDR)-TB...

We report the construction of a novel Systems Biology based virtual drug discovery model for the prediction of non-toxic metabolic targets in Mycobacterium tuberculosis (Mtb). This is based on a data-intensive genome level analysis and the principle of conservation of the evolutionarily important genes. In the 1623 sequenced Mtb strains, 890 metabolic genes identified through a systems approach in Mtb were evaluated for non-synonymous mutations. The 33 genes showed none or one variation in the entire 1623 strains, including 1084 Russian MDR strains...

Mycobacterium tuberculosis (M.tb), the causative agent of tuberculosis (TB), is the current leading cause of death due to a single infectious organism. Although curable, the broad emergence of multi-, extensive-, extreme-, and total-drug resistant strains of M.tb has hindered eradication efforts of this pathogen. Furthermore, computational models predict a quarter of the world's population is infected with M.tb in a latent state, effectively serving as the largest reservoir for any human pathogen with the ability to cause significant morbidity and mortality...

BACKGROUND: Multi drug resistant tuberculosis (MDR-TB) poses formidable challenges to TB control due to its complex diagnostic and treatment challenges and often associated with a high rate of mortality. Accurate and rapid detection of MDR-TB is critical for timely initiation of treatment. Line Probe Assay (LPA) is a qualitative in vitro diagnostic test based on DNA-STRIP technology for the identification of the M. tuberculosis complex and its resistance to rifampicin (RMP) and/or isoniazid (INH)...

Control of multi-drug-resistant tuberculosis (MDR-TB) requires extensive, supervised chemotherapy because second-line anti-TB drugs have a narrower therapeutic range than first-line drugs. This study aimed to develop population pharmacokinetic (PK) models for second-line drugs in patients with MDR-TB, evaluate the recommended dosage regimens and, if necessary, suggest new dosage regimens. A prospective, single-centre PK study was performed on second-line anti-TB drugs in patients with MDR-TB. Moxifloxacin, cycloserine, p-aminosalicylic acid (PAS), kanamycin and other second-line drugs were administered to the patients...

Rapid molecular diagnostics have great potential to limit the spread of multi- and extensively drug-resistant tuberculosis (M/XDR-TB). These technologies detect mutations in the Mycobacterium tuberculosis (Mtb) genome that confer phenotypic drug resistance. However, there is little data published regarding the relationships between the detected Mtb resistance mutations and M/XDR-TB treatment outcomes, limiting our current ability to exploit the full potential of molecular diagnostics. We analyzed clinical, microbiological and sequencing data for 451 patients and their clinical isolates collected in a multinational, observational cohort study to determine if there was an association between Mtb resistance mutations and patient mortality...

Drug resistance in tuberculosis (TB) is the biggest global health challenge as it hinders the tuberculosis control program and makes the disease more worsen. Molecular methods interrupt the spread of drug resistance by facilitating the appropriate anti- tuberculosis therapy at correct time through rapid diagnosis of multi drug resistant (MDR) and extensively drug resistant tuberculosis (XDR-TB). In this study we standardized and evaluated the diagnostic utility of multiplex allele specific PCR (MAS-PCR) targeting gyrA D94G and rrs A1401G mutations for detection of resistance against two key drugs (ofloxacin and kanamycin) of second line anti tuberculosis treatment...

Linezolid is used increasingly for the treatment of multi-drug-resistant (MDR) and extensively-drug-resistant (XDR) tuberculosis (TB). However, linezolid can cause severe adverse events, such as peripheral and optical neuropathy or thrombocytopenia related to higher drug exposure. This study aimed to develop a population pharmacokinetic model to predict the area under the concentration curve (AUC) for linezolid using a limited number of blood samples. Data from patients with MDR-/XDR-TB who received linezolid and therapeutic drug monitoring as part of their TB treatment were used...

Drug resistance in tuberculosis predominantly, mono-resistance, multi drug resistance, extensively drug resistance and totally drug resistance have emerged as a major problem in the chemotherapy of tuberculosis. Failures of first and second line anti-tuberculosis drugs treatment leads to emergence of resistant Mycobacterium tuberculosis. Few genes are reported as the principal targets of the resistance and apart from the primary targets many explanations have been proposed for drug resistance but still some resistance mechanisms are unknown...

Tuberculosis is one of the infectious diseases with the greatest global burden, affecting millions of people. The rise of multi- and extensively-drug resistant forms of Mycobacterium tuberculosis over the last few decades has highlighted the urgent need for development of new drugs to treat the disease. Many drug development pipelines are based on in vitro assays examining a compound's effect on M. tuberculosis alone. These do not account for the effect of a compound on mammalian cells nor the interaction between host and pathogen...

Antimicrobial resistance is a global healthcare problem with a dwindling arsenal of usable drugs. Tuberculosis, caused by Mycobacterium tuberculosis, requires long-term combination therapy and multi- and totally-drug resistant strains have emerged. This study reports the antibacterial activity of cationic polymers against mycobacteria, which are distinguished from other Gram-positive bacteria by their unique cell wall comprising a covalently linked mycolic acid-arabinogalactan-peptidoglycan complex (mAGP), interspersed with additional complex lipids which helps them persist in their host...

In the last 2 decades, drug-resistant tuberculosis has become a threat and a challenge to worldwide public health. The diagnosis and treatment of these forms of tuberculosis are much more complex and prognosis clearly worsens as the resistance pattern intensifies. Nevertheless, it is important to remember that with the appropriatesystematic clinical management, most of these patients can be cured. These guidelines itemize the basis for the diagnosis and treatment of all tuberculosis patients, from those infected by strains that are sensitive to all drugs, to those who are extensively drug-resistant...

Adverse drug reactions (ADRs) recorded in national pharmacovigilance databases in developed countries have been analyzed. However, adverse reactions to fluoroquinolones were observed globally despite their wide use and safety concerns. We provided information on the pattern of adverse reactions to fluoroquinolones reported spontaneously to the National Pharmacovigilance Centre (NPC), Nigeria. ADRs to fluoroquinolones reported to the NPC, over a period of 12 years, were analyzed. Evaluation was done for annual reports, age and gender of patients, type of reporter, suspected fluoroquinolones and adverse reactions, onset and outcome of ADRs, and causality...

Hydrocephalus is a known complication of tuberculous meningitis (TBM). It is almost always present in patients who have had the disease for four to six weeks. However, hydrocephalus can also develop later in the disease course as seen in our 3 patients. All 3 patients had multi-drug resistant (MDR) tuberculosis (TB) and developed hydrocephalus after variable time after starting second line anti-tuberculous therapy (ATT). A 7 years old girl had hydrocephalus at onset of TBM and was shunted but the hydrocephalus increased in size after 6 months of being on second line ATT in spite of a patent ventricular peritoneal (VP) shunt...
