The bacteria that cause tuberculosis (TB) can develop resistance to the antimicrobial drugs used to cure the disease Multidrug-resistant tuberculosis (MDR-TB) is TB that does not respond to at least isoniazid and rifampicin the two most powerful anti-TB drugs
Definition of MDR TB amp XDR TB
WHO - XDR-TB Task Force Committee gave a much accepted definition of XDR-TB which defines it as resistance to at least rifampicin and isoniazid among the first line-anti tubercular drugs in addition to resistance to any fluroquinolones ie ofloxacin ciprofloxacin and levofloxacin and at least one of three injectable second line anti tubercular drugs ie amikacin kanamycin and capreomycin
Mechanism of Resistance
1 Conversion of wild type pan-susceptible strains to drug resistant strains during treatment (acquired resistance)
2 Increasing development of resistance in drug-resistant strains because of inappropriate chemotherapy (amplified resistance)
3 Transmission of drug-resistant cases (transmitted resistance)

TB TESTING
1 XPERT Test
The Xpert MTBRIF has been developed by the Foundation for Innovative New Diagnostics (FIND) who have partnered with the Cepheid Corporation and the University of Medicine and Dentistry of New JerseyThe Xpert (GeneXpert) MTBRIF test is a new molecular test for TB which diagnoses TB by detecting the presence of TB bacteria as well as testing for resistance to the drug Rifampicin

TB drugs for children
In 2006 the World Health Organisation (WHO) first published specific guidance for national TB
control programs on the management of TB in children This recommended that the first line
anti TB drugs that should be used for the treatment of TB in children should be
Isoniazid
Rifampicin
Pyrazinamide
Ethambutol
and Streptomycin

Causes of inadequate TB treatment
Doctors - as a cause of inadequate TB treatment
Inappropriate guidelines
Noncompliance with guidelines
Absence of guidelinesDrugs - as a cause of inadequate TB treatment
Poor quality
Irregular supply
Wrong delivery (dosecombination)
Drugs are unsuitable due to drug resistance
Patients - as a cause of inadequate TB treatment
Lack of informationLack of money for treatment andor transportActual or presumed side effectsLack of commitment to a long course of drugsMalabsorptionSocial barriers
Public health responsibilities of health care providers
1048766 Health care facilitiespractitioners managing confirmed MDR-TB patients should inform their respective District TB Officer regarding treatment initiation and outcome of all MDR-TB cases
1048766 prior to treatment initiation and on all follow up visits the patient and family members should be counseled on all aspects of MDR-TB
1048766 All house hold contacts of the MDR-TB patients should be screened for active TB disease
1048766 Infection control measureso All large health care facilities need to have an infection control (including airborne infection) plan and a team for implementation of measures to prevent nosocomial transmission of TB and other air-borne infections
1048766 Statements to the pressmedia on MDR-TB and XDR-TB should be made with extreme caution and after requisite verification and authentication
The Global Plan to Stop TB 2006ndash2015 has as its main targets
To meet the MDG target to have halted and begun to reverse the incidence of TB by 2015
To meet the Stop TB partnerships own targets to by 2015 halve prevalence and death rates from the 1990 baseline
Over the ten years of the plan 50 million people will be treated under DOTS Plus 800000 people will be treated for MDR TB and three million people with TB and HIV condashinfection will start antiretroviral therapy
By 2010 simple tests for use at peripheral levels of the health system will enable rapid sensitive detection of active TB at the first point of care and by 2015 there will be tests to identify those at greatest risk of progressing to active disease
The first new TB drug for 40 years will be introduced in 2010 and by 2015 the target will have nearly been reached of a new regime that will achieve cure in 1ndash2 months and that also will be effective against MDR TB
By 2015 there will be the first of a series of new safe effective TB vaccines
There were also aims of involving communities and TB control featuring on the political agendas of countries

TB TESTING
1 XPERT Test
The Xpert MTBRIF has been developed by the Foundation for Innovative New Diagnostics (FIND) who have partnered with the Cepheid Corporation and the University of Medicine and Dentistry of New JerseyThe Xpert (GeneXpert) MTBRIF test is a new molecular test for TB which diagnoses TB by detecting the presence of TB bacteria as well as testing for resistance to the drug Rifampicin

TB drugs for children
In 2006 the World Health Organisation (WHO) first published specific guidance for national TB
control programs on the management of TB in children This recommended that the first line
anti TB drugs that should be used for the treatment of TB in children should be
Isoniazid
Rifampicin
Pyrazinamide
Ethambutol
and Streptomycin

Causes of inadequate TB treatment
Doctors - as a cause of inadequate TB treatment
Inappropriate guidelines
Noncompliance with guidelines
Absence of guidelinesDrugs - as a cause of inadequate TB treatment
Poor quality
Irregular supply
Wrong delivery (dosecombination)
Drugs are unsuitable due to drug resistance
Patients - as a cause of inadequate TB treatment
Lack of informationLack of money for treatment andor transportActual or presumed side effectsLack of commitment to a long course of drugsMalabsorptionSocial barriers
Public health responsibilities of health care providers
1048766 Health care facilitiespractitioners managing confirmed MDR-TB patients should inform their respective District TB Officer regarding treatment initiation and outcome of all MDR-TB cases
1048766 prior to treatment initiation and on all follow up visits the patient and family members should be counseled on all aspects of MDR-TB
1048766 All house hold contacts of the MDR-TB patients should be screened for active TB disease
1048766 Infection control measureso All large health care facilities need to have an infection control (including airborne infection) plan and a team for implementation of measures to prevent nosocomial transmission of TB and other air-borne infections
1048766 Statements to the pressmedia on MDR-TB and XDR-TB should be made with extreme caution and after requisite verification and authentication
The Global Plan to Stop TB 2006ndash2015 has as its main targets
To meet the MDG target to have halted and begun to reverse the incidence of TB by 2015
To meet the Stop TB partnerships own targets to by 2015 halve prevalence and death rates from the 1990 baseline
Over the ten years of the plan 50 million people will be treated under DOTS Plus 800000 people will be treated for MDR TB and three million people with TB and HIV condashinfection will start antiretroviral therapy
By 2010 simple tests for use at peripheral levels of the health system will enable rapid sensitive detection of active TB at the first point of care and by 2015 there will be tests to identify those at greatest risk of progressing to active disease
The first new TB drug for 40 years will be introduced in 2010 and by 2015 the target will have nearly been reached of a new regime that will achieve cure in 1ndash2 months and that also will be effective against MDR TB
By 2015 there will be the first of a series of new safe effective TB vaccines
There were also aims of involving communities and TB control featuring on the political agendas of countries
