When overexpressed, they function as ATP-dependent efflux pumps able to extrude lipophilic drugs, especially ANTINEOPLASTIC AGENTS, from cells causing multidrug resistance (DRUG RESISTANCE, MULTIPLE). Although P-Glycoproteins share functional similarities to MULTIDRUG RESISTANCE-ASSOCIATED PROTEINS they are two distinct subclasses of ATP-BINDING CASSETTE TRANSPORTERS, and have little sequence homology.Mefloquine: A phospholipid-interacting antimalarial drug (ANTIMALARIALS). It is very effective against PLASMODIUM FALCIPARUM with very few side effects.Prospective Studies: Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.Salmonella typhi: A serotype of SALMONELLA ENTERICA which is the etiologic agent of TYPHOID FEVER.China: A country spanning from central Asia to the Pacific Ocean.Enterococcus faecium: A species of gram-positive, coccoid bacteria whose organisms are normal flora of the intestinal tract. Unlike ENTEROCOCCUS FAECALIS, this species may produce an alpha-hemolytic reaction on blood agar and is unable to utilize pyruvic acid as an energy source.Drug Synergism: The action of a drug in promoting or enhancing the effectiveness of another drug.Mice, Inbred BALB CMembrane Glycoproteins: Glycoproteins found on the membrane or surface of cells.Disease Notification: Notification or reporting by a physician or other health care provider of the occurrence of specified contagious diseases such as tuberculosis and HIV infections to designated public health agencies. The United States system of reporting notifiable diseases evolved from the Quarantine Act of 1878, which authorized the US Public Health Service to collect morbidity data on cholera, smallpox, and yellow fever; each state in the US has its own list of notifiable diseases and depends largely on reporting by the individual health care provider. (From Segen, Dictionary of Modern Medicine, 1992)Patient Isolation: The segregation of patients with communicable or other diseases for a specified time. Isolation may be strict, in which movement and social contacts are limited; modified, where an effort to control specified aspects of care is made in order to prevent cross infection; or reverse, where the patient is secluded in a controlled or germ-free environment in order to protect him or her from cross infection.Rifamycins: A group of ANTI-BACTERIAL AGENTS characterized by a chromophoric naphthohydroquinone group spanned by an aliphatic bridge not previously found in other known ANTI-BACTERIAL AGENTS. They have been isolated from fermentation broths of Streptomyces mediterranei.

(1/959) Tuberculous meningitis in South African urban adults.

We retrospectively reviewed 56 adults with culture-proven tuberculous meningitis (TBM), investigating clinical signs, cerebrospinal fluid (CSF) findings and outcome. There were 50 patients, aged 18-59 years, 39 with and 11 without human immunodeficiency virus (HIV) infection. Six were aged 60 years or older. Neurological signs of TBM in 18-59-year-olds were unaffected by HIV serostatus while, compared to those > or = 60 years of age, there were more patients with meningism (86.0% vs. 33.3%; p = 0.011) and fewer with seizures (12.0% vs. 50.0%; p = 0.046). The HIV-infected 18-59-year-olds had significantly more extrameningeal tuberculosis compared to the non-HIV-infected (76.9% vs. 9.1%; p = 0.0001) and 23.1% had 'breakthrough' TBM. CSF analysis revealed 12 patients (21.4%) with acellular fluid (more common in those > or = 60 years of age, p = 0.016), of whom three had completely normal CSF. A neutrophil predominance was found in 22 patients (39.3%). Only three patients (5.4%) had a positive CSF smear for acid-fast bacilli. In-hospital mortality occurred in 39 patients (69.1%), was similar in all study groups, and was not related to neurological stage. The diagnosis of TBM can be masked by lack of meningism in the elderly and by atypical CSF findings.  (+info)

(2/959) Epidemiology of drug-resistant tuberculosis in Texas.

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)

(3/959) Issues in the treatment of active tuberculosis in human immunodeficiency virus-infected patients.

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)

(4/959) Susceptibility of multidrug-resistant strains of Mycobacterium tuberculosis to amoxycillin in combination with clavulanic acid and ethambutol.

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)

(5/959) Rapid film-based determination of antibiotic susceptibilities of Mycobacterium tuberculosis strains by using a luciferase reporter phage and the Bronx Box.

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)

(6/959) rpoB mutations in multidrug-resistant strains of Mycobacterium tuberculosis isolated in Italy.

Mutations of rpoB associated with rifampin resistance were studied in 37 multidrug-resistant (MDR) clinical strains of Mycobacterium tuberculosis isolated in Italy. At least one mutated codon was found in each MDR strain. It was always a single-base substitution leading to an amino acid change. Nine different rpoB alleles, three of which had not been reported before, were found. The relative frequencies of specific mutations in this sample were different from those previously reported from different geographical areas, since 22 strains (59.5%) carried the mutated codon TTG in position 531 (Ser-->Leu) and 11 (29.7%) had GAC in position 526 (His-->Asp).  (+info)

(7/959) Multiple drug resistant tuberculosis: aetiology, diagnosis and outcome.

Tuberculosis is an increasing problem worldwide both in terms of disease burden and resistance to conventional antibiotic therapy. Studies of outbreaks involving resistant strains have highlighted the need for both improved infection control and the rapid provision of accurate susceptibility data. Each patient should undergo a risk assessment for possible resistance and those in whom risk factors exist should be investigated by means of rapid molecular techniques or other phenotypic methods, so that appropriate management can be instituted with minimal delay. The ultimate outcome will vary according to whether the patient is immunosuppressed, the time taken to make a diagnosis, the severity of disease as well as the degree of resistance. The prognosis can be improved when adequate antibiotic therapy is started as soon as resistance is suspected. Adjuncts to conventional treatment, such as surgery and perhaps immunotherapy may be considered when response to antimicrobial chemotherapy has been suboptimal.  (+info)

(8/959) Spread of strain W, a highly drug-resistant strain of Mycobacterium tuberculosis, across the United States.

Strain W, a highly drug-resistant strain of Mycobacterium tuberculosis, was responsible for large nosocomial outbreaks in New York in the early 1990s. To describe the spread of strain W outside New York, we reviewed data from epidemiologic investigations, national tuberculosis surveillance, regional DNA fingerprint laboratories, and the Centers for Disease Control and Prevention Mycobacteriology Laboratory to identify potential cases of tuberculosis due to strain W. From January 1992 through February 1997, 23 cases were diagnosed in nine states and Puerto Rico; 8 were exposed to strain W in New York before their diagnosis; 4 of the 23 transmitted disease to 10 others. Eighty-six contacts of the 23 cases are presumed to be infected with strain W; 11 completed alternative preventive therapy. Strain W tuberculosis cases will occur throughout the United States as persons infected in New York move elsewhere. To help track and contain this strain, health departments should notify the Centers for Disease Control and Prevention of cases of tuberculosis resistant to isoniazid, rifampin, streptomycin, and kanamycin.  (+info)

  • UNITAID was launched in 2006 by the governments of Britain, Brazil, Chile, France and Norway to give sustainable funding for the fight against HIV/AIDS, malaria and tuberculosis. (
  • Tuberculosis and HIV have been linked since the AIDS epidemic began. (
  • The Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund), international private organizations, local and international nongovernmental organizations (NGOs), and community-based organizations (CBOs) provided the mainstay of the response to HIV/AIDS, especially in the area of community mobilization. (
  • diagnosis
  • Molecular methods have considerable advantages for scaling up programmatic management of MDR-TB and surveillance of drug-resistant TB because they offer speed of diagnosis, standardized testing, potential high through-put, and fewer requirements for laboratory biosafety. (
  • resistance
  • Molecular methods that target drug resistance mutations are suitable approaches for rapid drug susceptibility testing to detect multidrug-resistant tuberculosis (MDR-TB). (
  • Of the 18 total INH-resistant specimens, 15 (83.3%) had mutations in the katG gene ( katG MUT1, Ser315Thr1 ), indicating high-level resistance, while 3 (14.7%) had mutations in the inhA promoter gene ( Cys15Thr ), indicating low-level resistance. (
  • Acquired MDR-TB develops when a person with a non-resistant strain of TB is treated inadequately, resulting in the development of antibiotic resistance in the TB bacteria infecting them. (
  • exogenous
  • Analyses modelled different levels of programme effectiveness of DOTS and DOTS-plus, and high (10%) and intermediate (3%) proportions of primary multidrug resistant tuberculosis, while accounting for exogenous reinfection. (
  • aerosol
  • In the developing world the development of nanoparticle-based aerosol vaccines for tuberculosis has potential applications using on a large scale at relatively low cost, and particularly attractive for use. (
  • Evaluation of the Safety and Immunogenicity of a Candidate Tuberculosis Vaccine, MVA85A, Delivered by Aerosol to the Lungs of Macaques. (
  • effectiveness
  • If implementation of DOTS-plus were to result in a decrease of just 5% in the effectiveness of DOTS, 16% more people would die with tuberculosis than under DOTS alone. (
  • They make the organism more resistant to chemical damage and dehydration, and limit the effectiveness of hydrophilic antibiotics and biocides. (
  • surveillance
  • Since 1986 (the first full year following implementation of the revised tuberculosis {TB} surveillance case definition), the reported rate of TB per 100,000 persons in New Jersey increased from 9.5 cases to 12.6 cases in 1992 (1). (
  • India
  • 1 International Union against Tuberculosis and Lung Disease (The Union), South-East Asia Office, New Delhi, India . (
  • India bears a disproportionately large burden of the world's tuberculosis rates, as it continues to be the biggest health problem in India. (
  • In Zarir Udwadia's report originated from the Hinduja Hospital in Mumbai, India explicitly discusses the drug-resistant effects and results. (
  • Those listed are all the bodily and personal causes of acquiring TB, but tuberculosis in India is rich in its high rates because of the pollution dispersed throughout the country. (
  • drug
  • This report presents the findings of the study and compares the hospital's rates of drug-resistant TB with previously reported rates, rates for other cities in New Jersey, and rates for the state. (
  • The main uses are infections of the skin and pneumonia although it may be used for a variety of other infections including drug resistant tuberculosis. (
  • This issue of drug-resistant TB began with MDR-TB, and moved on to XDR-TB. (
  • deaths
  • The cumulative number of tuberculosis deaths per 100 000 population over 10 years. (
  • Of the 10 deaths on bedaquiline, 1 was due to a motor vehicle accident, 5 were judged as due to progression of the underlying tuberculosis and 3 were well after the patient had stopped receiving bedaquiline. (
  • 220, 000 deaths are reported due to Tuberculosis. (
  • global
  • The course is written by the New Jersey Medical School Global Tuberculosis Institute and supported by the MDR-TB partnership. (
  • diagnostic
  • Percentage change in total tuberculosis notifications by diagnostic center participating in the survey, Somalia, 2007-2010. (
  • Culture conversion is a diagnostic criteria indicating the point at which samples taken from a patient infected with a tuberculosis can no longer produce tuberculosis cell cultures. (
  • diseases
  • PIH's community-based model has proved successful in delivering effective care both for common conditions like diarrhea, pneumonia, and childbirth that are often fatal for Haiti's poor and malnourished, and for complex diseases like HIV and tuberculosis. (
