Mdr Tuberculosis: Symptoms and Risks
MDR Tuberculosis, short for Multi-Drug Resistant Tuberculosis, is a form of tuberculosis that does not respond to the standard antibiotics used to treat the disease. This type of tuberculosis poses a significant threat to public health as it is more challenging to treat and control than drug-sensitive tuberculosis. MDR TB can have a serious impact on an individual's health, leading to prolonged illness, increased risk of complications, and higher mortality rates compared to drug-sensitive TB. It requires specialized care and treatment to effectively manage the disease and prevent its spread to others.
What are the Symptoms of Mdr Tuberculosis
MDR Tuberculosis symptoms typically involve a range of respiratory and systemic manifestations that can be severe and prolonged.
- Persistent cough
- Chest pain
- Fever
- Night sweats
- Weight loss
- Fatigue
- Blood in sputum

Get Second OpinionCauses of Mdr Tuberculosis
The primary causes of Multi-Drug Resistant Tuberculosis (MDR-TB) include inadequate treatment adherence and inappropriate prescription of anti-TB medications.
- Inadequate treatment or incorrect medication
- Poor patient adherence to prescribed treatment
- Inappropriate use of medications
- Drug resistance due to genetic mutations
- Transmission of drugresistant strains from person to person
- HIV infection leading to compromised immunity
Types of Mdr Tuberculosis
MDR Tuberculosis can present in various forms, each requiring specific treatment approaches for effective management and control.
- MultidrugResistant Tuberculosis (MDRTB): TB that is resistant to at least two of the most powerful firstline antibiotics, isoniazid and rifampicin.
- Extensively DrugResistant Tuberculosis (XDRTB): A severe form of MDRTB that is also resistant to fluoroquinolones and at least one of three injectable secondline drugs.
- Preextensively DrugResistant Tuberculosis (PreXDRTB): TB that is resistant to isoniazid and rifampicin, as well as either a fluoroquinolone or a secondline injectable drug.
- Totally DrugResistant Tuberculosis (TDRTB): A rare form of TB that is resistant to all firstline and secondline antiTB drugs.
- Monoresistant Tuberculosis: TB that is resistant to only one firstline antiTB drug, usually isoniazid or rifampicin.
Risk Factors
MDR Tuberculosis risk factors include incomplete treatment of TB, improper use of medications, and exposure to TB patients who are not on proper treatment, which can lead to the development of drug resistance.
- Previous treatment for TB
- Nonadherence to TB medication
- Poor infection control in healthcare settings
- HIV infection
- Substance abuse
- Homelessness or living in crowded settings
- Malnutrition
- Diabetes
- Immunosuppressive therapy
- Close contact with someone with MDRTB

Diagnosis of Mdr Tuberculosis
MDR Tuberculosis is typically diagnosed through a series of tests that examine a person's sputum, blood, and imaging results.
- Drug susceptibility testing
- Genotypic testing
- Chest Xray
- Molecular testing
- Sputum culture and smear microscopy
- Chest CT scan
Treatment for Mdr Tuberculosis
MDR Tuberculosis is typically treated with a combination of multiple medications to effectively combat the resistant strains of the disease.
- Directly Observed Therapy (DOT): Patients take medication under supervision to ensure adherence and prevent drug resistance.
- Combination Therapy: Multiple antibiotics are used simultaneously to target different strains of drugresistant TB bacteria.
- Individualized Treatment Plans: Tailored regimens based on drug susceptibility testing to optimize effectiveness and minimize side effects.
- Surgical Intervention: Surgery may be necessary to remove infected lung tissue in severe cases of MDRTB.
- Supportive Care: Nutritional support, psychosocial interventions, and monitoring for adverse effects are essential components of MDRTB treatment.

What is MDR tuberculosis?
MDR tuberculosis stands for multidrug-resistant tuberculosis, which is a form of tuberculosis that is resistant to the two most powerful first-line drugs used to treat the disease.
How is MDR tuberculosis diagnosed?
MDR tuberculosis is diagnosed through drug susceptibility testing, where samples are tested to determine which drugs can effectively treat the specific strain of tuberculosis.
What causes MDR tuberculosis?
MDR tuberculosis develops when TB bacteria become resistant to the medications used to treat regular TB, usually due to improper use of antibiotics or incomplete treatment regimens.
Is MDR tuberculosis contagious?
Yes, MDR tuberculosis is contagious and can be spread through the air by coughing, sneezing, or talking, just like regular TB.
How is MDR tuberculosis treated?
Treatment for MDR tuberculosis often involves a combination of second-line antibiotics taken for an extended period under close medical supervision. It may require specialized care in a hospital or TB treatment center.
