Antitubercular Agents
Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.
Mycobacterium tuberculosis
A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans. Growth tends to be in serpentine, cordlike masses in which the bacilli show a parallel orientation.
Structure-Activity Relationship
The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.
Microbial Sensitivity Tests
Any tests that demonstrate the relative efficacy of different chemotherapeutic agents against specific microorganisms (i.e., bacteria, fungi, viruses).
Thioacetazone
A thiosemicarbazone that is used in association with other antimycobacterial agents in the initial and continuation phases of antituberculosis regimens. Thiacetazone containing regimens are less effective than the short-course regimen recommended by the International Union Against Tuberculosis and are used in some developing countries to reduce drug costs. (From Martindale, The Extra Pharmacopoeia, 30th ed, p217)
Isoniazid
Antibacterial agent used primarily as a tuberculostatic. It remains the treatment of choice for tuberculosis.
Antibiotics, Antitubercular
Substances obtained from various species of microorganisms that are, alone or in combination with other agents, of use in treating various forms of tuberculosis; most of these agents are merely bacteriostatic, induce resistance in the organisms, and may be toxic.
Rifampin
A semisynthetic antibiotic produced from Streptomyces mediterranei. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms it inhibits DNA-dependent RNA polymerase activity by forming a stable complex with the enzyme. It thus suppresses the initiation of RNA synthesis. Rifampin is bactericidal, and acts on both intracellular and extracellular organisms. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p1160)
Ethambutol
An antitubercular agent that inhibits the transfer of mycolic acids into the cell wall of the tubercle bacillus. It may also inhibit the synthesis of spermidine in mycobacteria. The action is usually bactericidal, and the drug can penetrate human cell membranes to exert its lethal effect. (From Smith and Reynard, Textbook of Pharmacology, 1992, p863)
Tuberculosis, Ocular
Tuberculous infection of the eye, primarily the iris, ciliary body, and choroid.
Tuberculosis
Any of the infectious diseases of man and other animals caused by species of MYCOBACTERIUM.

Phenothiazines
Compounds containing dibenzo-1,4-thiazine. Some of them are neuroactive.
Tuberculosis, Male Genital
MYCOBACTERIUM infections of the male reproductive tract (GENITALIA, MALE).
Tuberculoma, Intracranial
A well-circumscribed mass composed of tuberculous granulation tissue that may occur in the cerebral hemispheres, cerebellum, brain stem, or perimeningeal spaces. Multiple lesions are quite common. Management of intracranial manifestations vary with lesion site. Intracranial tuberculomas may be associated with SEIZURES, focal neurologic deficits, and INTRACRANIAL HYPERTENSION. Spinal cord tuberculomas may be associated with localized or radicular pain, weakness, sensory loss, and incontinence. Tuberculomas may arise as OPPORTUNISTIC INFECTIONS, but also occur in immunocompetent individuals.
Tuberculosis, Cutaneous
Tuberculosis of the skin. It includes scrofuloderma and tuberculid, but not LUPUS VULGARIS.
Tuberculosis, Multidrug-Resistant
Tuberculosis resistant to chemotherapy with two or more ANTITUBERCULAR AGENTS, including at least ISONIAZID and RIFAMPICIN. The problem of resistance is particularly troublesome in tuberculous OPPORTUNISTIC INFECTIONS associated with HIV INFECTIONS. It requires the use of second line drugs which are more toxic than the first line regimens. TB with isolates that have developed further resistance to at least three of the six classes of second line drugs is defined as EXTENSIVELY DRUG-RESISTANT TUBERCULOSIS.
Tuberculosis, Pulmonary
MYCOBACTERIUM infections of the lung.

Epidemiology of drug-resistant tuberculosis in Texas. (1/3795)

During 1987-1996, over 22,000 tuberculosis cases were reported in Texas, at an average annual incidence rate of 12.5 cases per 100,000 population. Counties with the highest rates were located along the Mexico-Texas border and in northwestern Texas. Nine percent of cases were resistant to at least one of the five first-line antituberculosis drugs used for treatment. Almost 5 percent (4.6%) were resistant to isoniazid, either alone or in combination with other antibiotics; 2.3% were resistant to rifampin; and only 1.3% were resistant to both isoniazid and rifampin. Being a recurrent case, being foreign-born, being 20-39 years of age, and residing in a Mexico-Texas border county were independent risk factors for isoniazid resistance and rifampin resistance. Tuberculosis patients with human immunodeficiency virus (HIV) infection were more likely to have rifampin resistance and less likely to have isoniazid resistance than patients without HIV infection. Factors associated with multi-drug-resistant tuberculosis included a history of previous tuberculosis (relative risk (RR) = 4.91, 95% confidence interval (CI) 3.5-6.8), non-US birth (RR = 2.69, 95% CI 2.1-3.5), age younger than 20 years (RR = 1.97, 95% CI 1.1-3.5), age 20-39 years (RR = 1.82, 95% CI 1.3-2.6), and residence in a Mexico-Texas border county (RR = 2.33, 95% CI 1.8-3.1).  (+info)

Issues in the treatment of active tuberculosis in human immunodeficiency virus-infected patients. (2/3795)

Most HIV-infected patients with tuberculosis can be treated satisfactorily with standard regimens with expectations of good results. Treatment of tuberculosis in these patients has been complicated by the introduction of HAART, which relies on drugs that interfere with the most potent class of antituberculous medications. Rifampin-free regimens or regimens that employ rifabutin may be acceptable strategies for patients who are receiving protease inhibitors, although these regimens have not been rigorously evaluated in patients with AIDS. At present, there is good reason to believe that a 6-month course of a rifabutin-containing regimen or a 9-12-month course of a regimen of streptomycin, isoniazid, and pyrazinamide should be adequate therapy for most patients with drug-susceptible disease. As the treatment of HIV infection with antiretroviral agents evolves, the treatment of tuberculosis in patients with AIDS is likely to evolve as well. This will require careful coordination of antituberculosis and antiretroviral therapies.  (+info)

Reduced pyrazinamidase activity and the natural resistance of Mycobacterium kansasii to the antituberculosis drug pyrazinamide. (3/3795)

Pyrazinamide (PZA), an analog of nicotinamide, is a prodrug that requires conversion to the bactericidal compound pyrazinoic acid (POA) by the bacterial pyrazinamidase (PZase) activity of nicotinamidase to show activity against Mycobacterium tuberculosis. Mutations leading to a loss of PZase activity cause PZA resistance in M. tuberculosis. M. kansasii is naturally resistant to PZA and has reduced PZase activity along with an apparently detectable nicotinamidase activity. The role of the reduction in PZase activity in the natural PZA resistance of M. kansasii is unknown. The MICs of PZA and POA for M. kansasii were determined to be 500 and 125 micrograms/ml, respectively. Using [14C]PZA and [14C]nicotinamide, we found that M. kansasii had about 5-fold-less PZase activity and about 25-fold-less nicotinamidase activity than M. tuberculosis. The M. kansasii pncA gene was cloned on a 1.8-kb BamHI DNA fragment, using M. avium pncA probe. Sequence analysis showed that the M. kansasii pncA gene encoded a protein with homology to its counterparts from M. tuberculosis (69.9%), M. avium (65.6%), and Escherichia coli (28.5%). Transformation of naturally PZA-resistant M. bovis BCG with M. kansasii pncA conferred partial PZA susceptibility. Transformation of M. kansasii with M. avium pncA caused functional expression of PZase and high-level susceptibility to PZA, indicating that the natural PZA resistance in M. kansasii results from a reduced PZase activity. Like M. tuberculosis, M. kansasii accumulated POA in the cells at an acidic pH; however, due to its highly active POA efflux pump, the naturally PZA-resistant species M. smegmatis did not. These findings suggest the existence of a weak POA efflux mechanism in M. kansasii.  (+info)

Pharmacokinetics of ethambutol under fasting conditions, with food, and with antacids. (4/3795)

Ethambutol (EMB) is the most frequent "fourth drug" used for the empiric treatment of Mycobacterium tuberculosis and a frequently used drug for infections caused by Mycobacterium avium complex. The pharmacokinetics of EMB in serum were studied with 14 healthy males and females in a randomized, four-period crossover study. Subjects ingested single doses of EMB of 25 mg/kg of body weight under fasting conditions twice, with a high-fat meal, and with aluminum-magnesium antacid. Serum was collected for 48 h and assayed by gas chromatography-mass spectrometry. Data were analyzed by noncompartmental methods and by a two-compartment pharmacokinetic model with zero-order absorption and first-order elimination. Both fasting conditions produced similar results: a mean (+/- standard deviation) EMB maximum concentration of drug in serum (Cmax) of 4.5 +/- 1.0 micrograms/ml, time to maximum concentration of drug in serum (Tmax) of 2.5 +/- 0.9 h, and area under the concentration-time curve from 0 h to infinity (AUC0-infinity) of 28.9 +/- 4.7 micrograms.h/ml. In the presence of antacids, subjects had a mean Cmax of 3.3 +/- 0.5 micrograms/ml, Tmax of 2.9 +/- 1.2 h, and AUC0-infinity of 27.5 +/- 5.9 micrograms.h/ml. In the presence of the Food and Drug Administration high-fat meal, subjects had a mean Cmax of 3.8 +/- 0.8 micrograms/ml, Tmax of 3.2 +/- 1.3 h, and AUC0-infinity of 29.6 +/- 4.7 micrograms.h/ml. These reductions in Cmax, delays in Tmax, and modest reductions in AUC0-infinity can be avoided by giving EMB on an empty stomach whenever possible.  (+info)

Use of site-directed mutagenesis to probe the structure, function and isoniazid activation of the catalase/peroxidase, KatG, from Mycobacterium tuberculosis. (5/3795)

A series of mutants bearing single amino acid substitutions often encountered in the catalase/peroxidase, KatG, from isoniazid-resistant isolates of Mycobacterium tuberculosis has been produced by site-directed mutagenesis. The resultant enzymes were overexpressed, purified and characterized. Replacing Cys-20 by Ser abolished disulphide-bridge formation, but did not affect either dimerization of the enzyme or catalysis. The substitution of Thr-275, which is probably involved in electron transfer from the haem, by proline resulted in a highly unstable enzyme with insignificant enzyme activities. The most commonly occurring substitution in drug-resistant clinical isolates is the replacement of Ser-315 by Thr; this lowered catalase and peroxidase activities by 50% and caused a significant decrease in the KatG-mediated inhibition of the activity of the NADH-dependent enoyl-[acyl-carrier protein] reductase, InhA, in vitro. The ability of this enzyme to produce free radicals from isoniazid was severely impaired, as judged by its loss of NitroBlue Tetrazolium reduction activity. Replacement of Leu-587 by Pro resulted in marked instability of KatG, indicating that the C-terminal domain is also important for structural and functional integrity.  (+info)

Susceptibility of multidrug-resistant strains of Mycobacterium tuberculosis to amoxycillin in combination with clavulanic acid and ethambutol. (6/3795)

Thirty clinical isolates of Mycobacterium tuberculosis, 20 of which were multidrug-resistant (MDR), were tested for susceptibility to different combinations of amoxycillin, clavulanic acid and subinhibitory concentrations of ethambutol. beta-Lactamase production was assessed semiquantitatively with the nitrocefin method and susceptibility testing was performed with the BACTEC method. All isolates were beta-lactamase positive and were resistant to 16 mg/L amoxycillin. The MIC of amoxycillin in combination with clavulanic acid was > or =2 mg/L for 27/30 (90%) isolates. Addition of subinhibitory concentrations of ethambutol significantly reduced the MIC of amoxycillin for all tested isolates. Twenty-nine (97%) isolates had an MIC of amoxycillin of < or =0.5 mg/L when subinhibitory concentrations of ethambutol were added; this is well below the concentrations achievable in serum and tissue.  (+info)

Molecular evidence for heterogeneity of the multiple-drug-resistant Mycobacterium tuberculosis population in Scotland (1990 to 1997). (7/3795)

Multiple-drug-resistant Mycobacterium tuberculosis (MDR-MTB) has been well studied in hospitals or health care institutions and in human immunodeficiency virus-infected populations. However, the characteristics of MDR-MTB in the community have not been well investigated. An understanding of its prevalence and circulation within the community will help to estimate the problem and optimize the strategies for control and prevention of its development and transmission. In this study, MDR-MTB isolates from Scotland collected between 1990 and 1997 were characterized, along with non-drug-resistant isolates. The results showed that they were genetically diverse, suggesting they were unrelated to each other and had probably evolved independently. Several new alleles of rpoB, katG, and ahpC were identified: rpoB codon 525 (ACC-->AAC; Thr525Asn); katG codon 128 (CGG-->CAG; Arg128Gln) and codon 291 (GCT-->CCT; Ala291Pro); and the ahpC synonymous substitution at codon 6 (ATT-->ATC). One of the MDR-MTB isolates from an Asian patient had an IS6110 restriction fragment length polymorphism pattern very similar to that of the MDR-MTB W strain and had the same drug resistance-related alleles but did not have any epidemiological connection with the W strains. Additionally, a cluster of M. tuberculosis isolates was identified in our collection of 715 clinical isolates; the isolates in this cluster had genetic backgrounds very similar to those of the W strains, one of which had already developed multiple drug resistances. The diverse population of MDR-MTB in Scotland, along with a low incidence of drug-resistant M. tuberculosis, has implications for the control of the organism and prevention of its spread.  (+info)

Rapid film-based determination of antibiotic susceptibilities of Mycobacterium tuberculosis strains by using a luciferase reporter phage and the Bronx Box. (8/3795)

Detecting antibiotic resistance in Mycobacterium tuberculosis is becoming increasingly important with the global recognition of drug-resistant strains and their adverse impact on clinical outcomes. Current methods of susceptibility testing are either time-consuming or costly; rapid, reliable, simple, and inexpensive methods would be highly desirable, especially in the developing world where most tuberculosis is found. The luciferase reporter phage is a unique reagent well-suited for this purpose: upon infection with viable mycobacteria, it produces quantifiable light which is not observed in mycobacterial cells treated with active antimicrobials. In this report, we describe a modification of our original assay, which allows detection of the emitted light with a Polaroid film box designated the Bronx Box. The technique has been applied to 25 M. tuberculosis reference and clinical strains, and criteria are presented which allow rapid and simple discrimination among strains susceptible or resistant to isoniazid and rifampin, the major antituberculosis agents.  (+info)

Early diagnosis of tuberculosis (TB) and multidrug resistant tuberculosis (MDR TB) is important for the elimination of TB. We evaluated the microscopic observation drug susceptibility (MODS) assay as a direct rapid drug susceptibility testing (DST) method for MDR-TB screening in sputum samples All adult TB suspects, who were newly presenting to Pham Ngoc Thach Hospital from August to November 2008 were enrolled into the study. Processed sputum samples were used for DST by MODS (DST-MODS) (Rifampicin (RIF) 1 μg/ml and Isoniazid (INH) 0.4 μg/ml), MGIT culture (Mycobacterial Growth Indicator Tube) and Lowenstein Jensen (LJ) culture. Cultures positive by either MGIT or LJ were used for proportional DST (DST-LJ) (RIF 40 μg/ml and INH 0.2 μg/ml). DST profiles on MODS and LJ were compared. Discrepant results were resolved by multiplex allele specific PCR (MAS-PCR). Seven hundred and nine TB suspects/samples were enrolled into the study, of which 300 samples with DST profiles available from both MODS and

Rapid determination of anti-tuberculosis drug resistance from whole-genome sequences | Genome Medicine | Full TextRapid determination of anti-tuberculosis drug resistance from whole-genome sequences | Genome Medicine | Full Text
Mycobacterium tuberculosis drug resistance (DR) challenges effective tuberculosis disease control. Current molecular tests examine limited numbers of mutations, and although whole genome sequencing approaches could fully characterise DR, data complexity has restricted their clinical application. A library (1,325 mutations) predictive of DR for 15 anti-tuberculosis drugs was compiled and validated for 11 of them using genomic-phenotypic data from 792 strains. A rapid online TB-Profiler tool was developed to report DR and strain-type profiles directly from raw sequences. Using our DR mutation library, in silico diagnostic accuracy was superior to some commercial diagnostics and alternative databases. The library will facilitate sequence-based drug-susceptibility testing.

Review of Evidence for Measuring Drug Concentrations of First-Line Antitubercular Agents in AdultsReview of Evidence for Measuring Drug Concentrations of First-Line Antitubercular Agents in Adults
Measurement of drug concentrations and performing therapeutic drug monitoring (TDM) are widely used to optimize efficacy and safety of many commonly used drugs today. Although TDM of first-line antitubercular drugs is used during the treatment of tuberculosis, the extent of any benefit achieved is currently unknown. This review summarizes the available literature describing TDM of first-line treatment agents in patients with tuberculosis and describes clinical associations with achievement of target drug concentrations, including data from special populations. A literature review was conducted for articles describing drug concentration and TDM outcomes for first-line tuberculosis agents in adults. A total of 40 studies were included in the review. Studies were a mixture of controlled trials, observational studies, cross-sectional studies, and case reports. The majority of the studies showed standard dosing does not consistently achieve target concentrations for the first-line antitubercular ...

Title: Recent Development and Future Perspective of Antitubercular Therapy. VOLUME: 9 ISSUE: 2. Author(s):Mahesh Chhabria, Shailesh Patel and Mitesh Jani. Affiliation:Department of Pharmaceutical Chemistry, L.M. College of Pharmacy, Ahmedabad, Gujarat 380 009, India.. Keywords:Mycobacterium tuberculosis, MDR, &, XDR TB, novel targets, ligands. Abstract: Tuberculosis (TB) has remained an enemy of humankind before the beginning of recorded history. Although it is curable and preventable, TB claims the lives of more than 5,000 people every day. Despite of availability of effective chemotherapy and BCG vaccine in 21st century, TB remains one of the most deadly infectious diseases. The concomitant resurgence of TB with the Multi-drug resistant (MDR) or Extremely drug resistant (XDR)-TB and HIV/AIDS pandemic raises the threat posed by untreatable and fatal human TB, exposing the frailties of the current drug armatorium. No new drug is available acting through novel mechanism since last 40 years. The ...

Prediction of Susceptibility to First-Line Tuberculosis Drugs by DNA Sequencing. - MIDASPrediction of Susceptibility to First-Line Tuberculosis Drugs by DNA Sequencing. - MIDAS
We obtained whole-genome sequences and associated phenotypes of resistance or susceptibility to the first-line antituberculosis drugs isoniazid, rifampin, ethambutol, and pyrazinamide for isolates from 16 countries across six continents. For each isolate, mutations associated with drug resistance and drug susceptibility were identified across nine genes, and individual phenotypes were predicted unless mutations of unknown association were also present. To identify how whole-genome sequencing might direct first-line drug therapy, complete susceptibility profiles were predicted. These profiles were predicted to be susceptible to all four drugs (i.e., pansusceptible) if they were predicted to be susceptible to isoniazid and to the other drugs or if they contained mutations of unknown association in genes that affect susceptibility to the other drugs. We simulated the way in which the negative predictive value changed with the prevalence of drug resistance ...

Multidrug-resistant tuberculosis (TB) threatens TB control worldwide. The microscopic observation drug susceptibility (MODS) assay is a low-cost, high-performance TB diagnostic tool for rapid liquid culture and direct isoniazid and rifampicin drug susceptibility testing (DST). The objective of this study was to explore the potential for extending the MODS assay to rapid second-line DST and to identify critical concentrations of candidate drugs for prospective testing. Sputum samples from 94 TB culture-positive patients receiving second-line TB agents were cultured following standardised MODS protocols, with a range of titrations of antimicrobial drugs added. Critical concentrations were determined using a modified Kaplan-Meier survival curve analysis. Candidate critical concentrations were determined for capreomycin (10 mu g.mL(-1)), ciprofloxacin (1.25 mu g.mL(-1)), cycloserine (40 mu g.mL(-1)), ethambutol (10 mu g.mL(-1)), ethionamide (5 mu g.mL(-1)), kanamycin (5 mu g.mL(-1)) ...

With the global rise of MDR strains, there is an increasing need to determine susceptibility to first and second-line anti-TB agents exactly. Treatment of patients with drug-resistant TB should be based on reliable and quantitative measures of susceptibility testing, a cornerstone for preventing further amplification of resistance (18) and for optimally exploiting available compounds. Detailed knowledge on quantitative drug resistance may guide empirical treatment of drug-resistant TB, e.g., addressing whether and when to add second-line drugs. A fundamental drawback to this strategy is that even in industrialized countries, only a limited panel of anti-TB drug concentrations is tested, leaving the exact resistance level of clinical M. tuberculosis isolates vestigial. In principle, automatic systems have the potential to meet the challenge of precise determinations of drug resistance levels with reasonable labor input. The MGIT 960 platform has been extensively validated for testing ...

Background. In Tomsk Oblast, Russian Federation, during the period of 1996-2000, most previously untreated patients with tuberculosis received standardized short-course chemotherapy, irrespective of drug-susceptibility testing results. A retrospective analysis was done to determine the effect of initial drug resistance on treatment outcome and acquired drug resistance in new patients receiving standardized short-course chemotherapy.. Methods. During the period of 1 November 1996 through 31 December 2000, a total of 2194 patients received a category 1 treatment regimen. Drug susceptibility test results for 1681 patients were available for analysis. Drug resistance patterns before and during treatment were compared for 73 patients whose culture results were persistently positive during treatment. Acquired resistance was defined as new drug resistance (during or at the end of treatment) that was not present at the beginning of treatment.. Results. Pretreatment drug resistance was strongly ...

Malnourished children in India below three years are underdosed for first-line TB drugs - Science ChronicleMalnourished children in India below three years are underdosed for first-line TB drugs - Science Chronicle
The ultimate goal of evidence-based drug treatment is to produce a desired pharmacological response in a predictable manner and also to minimise adverse effects, notes a June 2013 paper published in the International Journal of Tuberculosis and Lung Disease. The two goals can be achieved only when the correct therapeutic drug dosage of anti-TB drugs required by children, particularly those younger than five years, and the age-related differences in toxicity and pharmacokinetics are well studied and known.. Pharmacokinetics is the metabolism of the drugs in humans, Dr. Peter R. Donald, Emeritus Professor in the Department of Paediatrics and Child Health of the Faculty of Health Sciences at Stellenbosch University, South Africa said in an email to this Correspondent. The pharmacokinetics of first-line anti-TB drugs is not known for children younger than two years.. Since children have relatively greater mass of liver in proportion to total body weight, they metabolise and eliminate drugs ...

TB is the cause of the largest killer of humanity, killing nearly 2 million people each year. The poor efficacy of existing TB drugs requires that they be administered in a multi drug regimen for at least six months. This results in poor patient compliance and leads to development of multidrug-‐resistant TB (MDR-‐TB) and extremely drug-‐resistant TB (XDR-‐TB). Decades of misuse of existing antibiotics and poor compliance have created an epidemic of drug resistance that threatens TB control programs worldwide ...

Evaluation of optimized bronchoalveolar lavage sampling designs for characterization of pulmonary drug distributionEvaluation of optimized bronchoalveolar lavage sampling designs for characterization of pulmonary drug distribution
With approximately nine million new cases and the attributable cause of death of an estimated two millions people every year there is an urgent need for new and effective drugs and treatment regimens targeting tuberculosis. The tuberculosis drug development pathway is however not ideal, containing non-predictive model systems and unanswered questions that may increase the risk of failure during late-phase drug development. The aim of this thesis was hence to develop pharmacometric tools in order to optimize the development of new anti-tuberculosis drugs and treatment regimens.. The General Pulmonary Distribution model was developed allowing for prediction of both rate and extent of distribution from plasma to pulmonary tissue. A distribution characterization that is of high importance as most current used anti-tuberculosis drugs were introduced into clinical use without considering the pharmacokinetic properties influencing drug distribution to the site of action. The developed optimized ...

Isoniazid preventive therapy is a key public health intervention for the prevention of tuberculosis disease among people living with HIV. Despite the confirmed efficacy of isoniazid preventive therapy and global recommendations existing for decades, its implementation remains limited. In resource constrained settings, few have investigated why isoniazid preventive therapy is not implemented on full scale. This study was designed to investigate the level of isoniazid preventive therapy implementation and reasons for suboptimal implementation in Tigray region of Ethiopia. A review of patient records combined with a qualitative study using in-depth interviews and focus group discussions was conducted in 11 hospitals providing isoniazid preventive therapy in the Tigray Region. The study participants were health providers working in the HIV clinics of the 11 hospitals in the province. Health providers were interviewed about their experience of providing isoniazid preventive therapy and challenges faced

The microscopic observation drug susceptibility assay (MODS) is a novel and promising test for the early diagnosis of tuberculosis (TB). We evaluated the MODS assay for the early diagnosis of TB in HIV-positive patients presenting to Pham Ngoc Thach Hospital for Tuberculosis and Lung Diseases in southern Vietnam. A total of 738 consecutive sputum samples collected from 307 HIV-positive individuals suspected of TB were tested by smear, MODS, and the mycobacteria growth indicator tube method (MGIT). The diagnostic sensitivity and specificity of MODS compared to the microbiological gold standard (either smear or MGIT) were 87 and 93%, respectively. The sensitivities of smear, MODS, and MGIT were 57, 71, and 75%, respectively, against clinical gold standard (MODS versus smear, P|0.001; MODS versus MGIT, P=0.03). The clinical gold standard was defined as patients who had a clinical examination and treatment consistent with TB, with or without microbiological confirmation. For the diagnosis of smear-negative

EDITOR-Lawn and Wilkinson report on the global emergence of extensively drug resistant tuberculosis.1 An outbreak of extensively drug resistant tuberculosis has been ongoing for a decade in Norway.2 In 1994 treatment was started in a patient with pulmonary tuberculosis who was lost to follow-up. One year later, the same patient was admitted to hospital with smear positive, pulmonary, extensively drug resistant tuberculosis.2 In the following 10 years, 23 other patients were diagnosed with a strain of Mycobacterium tuberculosis that carried the same IS6110 RFLP and spoligotyping DNA patterns. Of these, 15 had extensively drug resistant tuberculosis (table). Among 3131 patients diagnosed with tuberculosis in Nor-way during these 12 years M tuberculosis was isolated from 2284. Multidrug resistant tuberculosis was identified in 37 of them. The 15 cases of extensively drug resistant tuberculosis in the current outbreak are 0.66% of all culture positive cases and 40% of the multidrug resistant cases ...

In the context of tuberculosis (TB) resurgence, isoniazid preventive therapy (IPT) is increasingly promoted, but concerns about the risk for development of isoniazid-resistant tuberculosis may hinder its widespread implementation. We conducted a systematic review of data published since 1951 to assess the effect of primary IPT on the risk for isoniazid-resistant TB. Different definitions of isoniazid resistance were used, which affected summary effect estimates; we report the most consistent results. When all 13 studies (N = 18,095 persons in isoniazid groups and N = 17,985 persons in control groups) were combined, the summary relative risk for resistance was 1.45 (95% confidence interval 0.85-2.47). Results were similar when studies of HIV-uninfected and HIV-infected persons were considered separately. Analyses were limited by small numbers and incomplete testing of isolates, but findings do not exclude an increased risk for isoniazid-resistant TB after IPT. The diagnosis of active TB should be

To determine differences in the ability of Mycobacterium tuberculosis strains to withstand antituberculosis drug treatment, we compared the activity of antituberculosis drugs against susceptible Beijing and East-African/Indian genotype M. tuberculosis strains. Beijing genotype strains showed high rates of mutation within a wide range of drug concentrations, possibly explaining this genotypes association with multidrug-resistant tuberculosis.

Evidence exists pointing out how non-adherence to treatment remains a major hurdle to efficient tuberculosis control in developing countries. Many tuberculosis (Tb) patients do not complete their six-month course of anti-tuberculosis medications and are not aware of the importance of sputum re-examinations, thereby putting themselves at risk of developing multidrug-resistant and extensively drug-resistant forms of tuberculosis and relapse. However, there is a dearth of publications about non-adherence towards anti-Tb medication in these settings. We assessed the prevalence of and associated factors for anti-Tb treatment non-adherence in public health care facilities of South Ethiopia. This was a cross-sectional survey using both quantitative and qualitative methods. The quantitative study was conducted among 261 Tb patients from 17 health centers and one general hospital. The qualitative aspect included an in-depth interview of 14 key informants. For quantitative data, the analysis of descriptive

Early detection of resistance to second-line anti-tuberculosis drugs is important for the management of multidrug-resistant (MDR)-TB. The Genotype® MTBDRsl VERSION 2.0 (VER 2.0) line probe assay has been redesigned for molecular detection of resistance-conferring mutations of fluoroquinolones (FLQ) (gyrA and gyrB genes) and second-line injectable drugs (SLID) (rrs and eis genes). The study evaluated the diagnostic performance of MTBDRsl VER 2.0 for the detection of second-line drug resistance compared with phenotypic drug susceptibility testing (DST), using the Bactec™ MGIT 960 system on Mycobacterium tuberculosis complex isolates from South Africa. A total of 268 repository isolates collected between 2012 and 2014, with rifampicin -mono-resistant (RR) or MDR based on DST were selected. MTBDRsl VER 2.0 testing was performed on these isolates and results analysed.

Many cases, particularly in low-prevalence settings, result from the reactivation of latent tuberculosis infection (LTBI); potentially acquired years prior to active disease. Up to one-third of the world’s population has been infected with LTBI, and so may be at risk for future active TB disease. A variety of antituberculosis medications and treatment regimens have now been evaluated in the management of LTBI, with the aim of eradicating tuberculosis bacilli and reducing the likelihood of subsequent reactivation disease.

Tuberculosis (TB) is the most common opportunistic infection and the leading cause of death in people living with HIV (PLHIV). HIV-infected children are at a higher risk of TB infection and disease compared to those without HIV. Isoniazid preventive therapy (IPT) is an effective intervention in preventing progression of latent TB infection to active TB. The World Health Organization (WHO) currently recommends that all children aged | 12 months and adults living with HIV in whom active TB has been excluded should receive a 6-months course of IPT as part of a comprehensive package of HIV care. Despite this recommendation, the uptake of IPT among PLHIV has been suboptimal globally. This study sought to determine the factors affecting IPT uptake and completion among HIV-infected children in a large HIV care centre in Nairobi, Kenya. This was a cross-sectional mixed methods study comprising of quantitative and qualitative study designs. Medical records of 225 HIV-infected children aged 1 to | 10 years, in

Queen Mary University Hospital, London, United Kingdom. MedicalResearch.com: What is the background for this study? What are the main findings?. Response: Multidrug resistant tuberculosis (MDR-TB) has been on the increase worldwide over the past decade. Many patients who have been identified with MDR-TB live in the European region. Despite treatment with expensive second-line drug regimens, curing MDR TB remains a challenge and cure rates were thought to be very low. As part of the EU Commission funded TB-PANNET project 380 patients with MDR-TB were observed at 23 TB centers in countries of high, intermediate and low TB burden in Europe over a period of 5 years. Observation started from the time of diagnosis and lasted until one year after the end of the treatment.. The TBNET proposed new definitions for cure and failure of MDR-TB treatment based on the sputum culture status at 6 month after the initiation of therapy and whether patients were free from disease recurrence one year after the ...

Tuberculosis (TB) disease is a common opportunistic infection among people living with HIV (PLHIV). WHO recommends at least 6 months of isoniazid Preventive Therapy (IPT) to reduce the risk of active TB. It is important to monitor the six-month IPT completion since a suboptimal dose may not protect PLHIV from TB infection. This study determined the six-month IPT completion and factors associated with six-month IPT completion among PLHIV aged 15 years or more in Dar es Salaam region, Tanzania. Secondary analysis of routine data from PLHIV attending 58 care and treatment clinics in Dar es Salaam region was used. PLHIV, aged 15 years and above, who screened negative for TB symptoms and initiated IPT from January, 2013 to June, 2017 were recruited. Modified Poisson regression with robust standard errors was used to estimate prevalence ratios (PR) and 95% confidence interval (CI) for factors associated with IPT completion. Multilevel analysis was used to account for health facility random effects in order to

The place of prodrugs in the current antitubercular therapeutic arsenal is preponderant, since two of the four first-line antitubercular agents, isoniazid (INH) and pyrazinamide (PZA), need to be activated by Mycobacterium tuberculosis before exerting their activity. In addition, six other prodrugs can be found in the second- and third-line therapeutic regimens. The emergence of mycobacterial strains resistant to one or several antitubercular agents is one of the main issues of the antitubercular therapy. In the case of prodrugs, the resistance phenomenon is often related to a mutation in the gene encoding for the activation enzymes, resulting thus in a default of these enzymes that are no more able to activate prodrugs ...

The Efficacy of Interferon-α in the Treatment of Multidrug Resistant TuberculosisThe Efficacy of Interferon-α in the Treatment of Multidrug Resistant Tuberculosis
Background: Tuberculosis is a major cause of infectious disease mortality all over the world. Multidrug resistant tuberculosis (MDR-TB) is a major problem in the management of tuberculosis. With recent advances in understanding the immunopathogenesis of tuberculosis, the use of various cytokine therapies has been suggested. The objective of this study was to evaluate the efficacy of parenteral INF- for treating MDR-TB patients. Materials and Methods: To conduct the study, 12 MDR- TB patients hospitalised in the clinical mycobacteriology ward of Massih Daneshvari hospital were selected randomly between October 2000 and March 2001. All had chest involvement in radiography, so they were smear and culture positive on two occasions. All had at least resistance to isoniazid and rifampin in antibiogram. They were divided in two groups. One group received INF- ; (3,000,000U, three times a week, subcutaneously) in addition to anti-TB drugs, and the other group received only anti -TB medications as control group.

Treatment success rates of multidrug-resistant tuberculosis (MDR-TB) remain unsatisfactory, and long-term use of second-line anti-TB drugs is accompanied by the frequent occurrence of adverse events, low treatment compliance, and high costs. The development of new efficient regimens with shorter treatment durations for MDR-TB will solve these issues and improve treatment outcomes. This study is a phase II/III, multicenter, randomized, open-label clinical trial of non-inferiority design comparing a new regimen to the World Health Organization-endorsed conventional regimen for fluoroquinolone-sensitive MDR-TB. The control arm uses a conventional treatment regimen with second-line drugs including injectables for 20-24 months. The investigational arm uses a new shorter regimen including delamanid, linezolid, levofloxacin, and pyrazinamide for 9 or 12 months depending on time to sputum culture conversion. The primary outcome is the treatment success rate at 24 months after treatment initiation. Secondary

PARN » Emergence of Extensively Resistant TuberculosisPARN » Emergence of Extensively Resistant Tuberculosis
Tuberculosis is usually treated with first-line anti-tuberculous drugs such as isoniazid, rifampin, ethambutol, and pyrazinamide.. Multi-drug resistant tuberculosis (MDR) is disease due to strains resistant to both isoniazid and rifampicin. Treatment of such strains requires use of second-line drugs which include fluoroquinolones, aminoglycosides, capreomycin (injectable drugs), para-aminosalicylate, cycloserine, and ethionamide.. Recently, however, strains resistant to fluoroquinolones have been noticed worldwide. When MDR TB strains become resistant to fluoroquinolones, treatment becomes difficult since other drugs used have limited efficacy. Treatment options become even more limited when in addition to fluoroquinolones, strains are resistant to any one of the injectable drugs. Such strains are labeled extensively drug resistant (XDR).. Patients with XDR TB require longer duration of treatment (at least 18 months) with drugs regimens that incorporate both old and new agents. Newer drugs ...

Tuberculosis (TB) is a disease that produces several million deaths annually. With the appearance of multi drug resistant microbial strains of Mycobacterium tuberculosis, innovations in TB drug discovery and evolving strategies to bring new agents with best performance is an essential investigation. Taking this into account, there is a pressing need to develop new and more effective anti tubercular agents. The coordination of metal with organic drugs is a promising strategy that has been successful in many cases with different pharmacological activities. The emergence of new cases and the adverse effects of first and second-line antituberculosis drugs have led to renewed research interest in metal drug complexes in the hope of discovering new antituberculosis drugs. The aim of the present study is to assess the antituberculosis activity of Ni (II) and Cu (II) complexes of polymer ligand poly (3-nitrobenzylidene-1-naphthylamine-co-methacrylic acid). ...

All of the 87 INH-resistant isolates from China had mutations in the nine structural genes (furA, katG, inhA, kasA, Rv0340, iniB, iniA, iniC, and efpA) or two regulatory regions (the oxyR-ahpC intergenic region and the promoter of mabA-inhA). Thirty-nine distinct mutations were identified. Among these, mutations in the katG gene were predominant, as expected; katG mutations were found in 82 (94.3%) isolates. Geographical differences in the frequencies of the katG codon 315 mutations were apparent in the analysis of data from other studies: mutations in katG codon 315 were detected in only 34.6% of the INH-resistant isolates from Madrid (18) but were detected in a substantial 93.6% of isolates from northwest Russia (26). Therefore, the documented information regarding the frequencies and types of mutations in one country or geographical region may not apply generally to other regions. We found mutations in katG codon 315 in 64.4% of the INH-resistant isolates from five provinces of China, which ...

Bergen Open Research Archive: Childhood tuberculosis case management in Pakistan: Addressing a priorityBergen Open Research Archive: Childhood tuberculosis case management in Pakistan: Addressing a priority
Childhood tuberculosis is considered a major cause of morbidity and mortality in high burden TB countries. It has had a low priority for research and development globally and was not given much attention in the past on ways and means to operationalize the case management strategies within the context of National TB Control Programmes. The current thesis focuses on various cohorts of childhood TB and audit of the case management practices within the routine national TB control programme of Pakistan. The thesis also documents the lessons learned during this research and development. Our initial retrospective cohorts were based on the review of patient records, focused on the case notification, treatment outcomes and case management practices of patients registered during two complete years 2004 and 2005, when NTP had no particular emphasis on childhood TB and had recently expanded the DOTS strategy for adults. These results we compared with those of patients registered during 2006 and 2007, when ...

The comorbidities of tuberculosis and diseases such as HIV require long-term treatment with multiple medications. Despite substantial in vitro and in vivo information on effects of rifampicin and isoniazid on human CYPs, there is limited published data regarding the inhibitory effects of other anti-TB drugs on human CYPs and UGTs. The inhibitory effects of 5 first-line anti-TB drugs (isoniazid, rifampicin, pyrazinamide, ethambutol, and rifabutin), and the newly approved bedaquiline, were evaluated for 6 common human hepatic UGT enzymes (UGT1A1, 1A4, 1A6, 1A9, 2B7 and 2B15) in vitro using HLMs. Pyrazinamide, ethambutol, rifabutin and bedaquiline were also studied for their inhibitory effects on 8 of the most common human CYP enzymes (CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1 and 3A). Rifabutin inhibited multiple CYPs to varying degrees in vitro, but with all IC50 values exceeding 25 μM. Rifabutin and rifampicin also inhibited several human UGTs including UGT1A4. The Ki value for rifabutin on human ...

During the 1990s, multidrug-resistant tuberculosis (MDR-TB), resistant to at least isoniazid and rifampin, emerged as a great threat to global tuberculosis (TB) control [1]. For most MDR-TB patients, the World Health Organization (WHO) recommends a treatment regimen including second-line anti-TB drugs [2]. One of the most effective second-line drugs is fluoroquinolone [3]. During the treatment, MDR-TB may develop resistance to fluoroquinolone, or even become extensively drug-resistant (XDR-TB), which is resistant to both fluoroquinolone and at least one of three injectable second-line drugs [4]. The main genetic mechanism of fluoroquinolone resistance lies in the mutations in the quinolone-resistance-determining region of gyrA and gyrB [5]. ...

Challenges and Outlooks in Multi-drug Resistant Tuberculosis | Archivos de Bronconeumología (English Edition)Challenges and Outlooks in Multi-drug Resistant Tuberculosis | Archivos de Bronconeumología (English Edition)
Drug-resistant tuberculosis (TB) has become one of the major obstacles currently encountered in the control of this disease worldwide.1 The widespread and sometimes inappropriate use of rifampicin in the last 40 years has generated a growing number of cases of rifampicin-resistant TB (RR-TB). Rifampicin resistance is the most decisive factor in the prognosis of TB patients.2 If this drug cannot be used, treatment must continue for at least 21-24 months, and combinations of less effective, more toxic drugs3 are required, leading to cure rates of only 50%.1 Moreover, more than 90% of RR-TB cases are also carriers of isoniazid (H)-resistant strains3; these patients make up the so-called multidrug-resistant TB (MDR-TB) group.. The problem is further compounded by the appearance and spread of cases of extensively drug-resistant TB (XDR-TB), which is MDR-TB that is also resistant to the fluoroquinolones (FQ: levofloxacin and/or moxifloxacin) and second-line injectable drugs (SLID: amikacin and/or ...

High Prevalence of Primary Multidrug Resistant Tuberculosis in Persons with No Known Risk FactorsHigh Prevalence of Primary Multidrug Resistant Tuberculosis in Persons with No Known Risk Factors
Introduction In high multidrug resistant (MDR) tuberculosis (TB) prevalence areas, drug susceptibility testing (DST) at diagnosis is recommended for patients with risk factors for MDR. However, this approach might miss a substantial proportion of MDR-TB in the general population. We studied primary MDR in patients considered to be at low risk of MDR-TB in Lima, Peru. Methods We enrolled new sputum smear-positive TB patients who did not report any MDR-TB risk factor: known exposure to a TB patient whose treatment failed or who died or who was known to have MDR-TB; immunosuppressive co-morbidities, ex prison inmates; prison and health care workers; and alcohol or drug abuse. A structured questionnaire was applied to all enrolled participants to confirm the absence of these factors and thus minimize underreporting. Sputum from all participants was cultured on Löwenstein-Jensen media and DST for first line drugs was performed using the 7H10 agar method. Results Of 875 participants with complete data,

Although our baseline analysis assumed that DOTS-plus can be implemented effectively, the proportion of patients completing even standard treatment regimens is low in areas where multidrug resistant tuberculosis has become a major problem.21 In areas where direct smear microscopy and giving two to four relatively non-toxic drugs for six months is impossible, routinely performing mycobacterial cultures and first and second line susceptibility testing as well as administering four to seven toxic drugs for 18-24 months is unlikely to be possible.. A tuberculosis control programme should have implemented effective DOTS before implementing DOTS-plus.28 A poorly run control programme can generate multidrug resistant tuberculosis, but effective DOTS can decrease the rates of multidrug resistant tuberculosis.29 More widespread implementation of effective DOTS would therefore decrease the number of cases for which DOTS-plus would be necessary.30 Currently, 77% of tuberculosis cases worldwide are not ...
