Drug resistance in tuberculosis and options available
Journal of the Indian Medical Association
|September 16, 2010
Summary
Drug-resistant tuberculosis (TB) poses a significant threat. Understanding resistance mechanisms and implementing effective control strategies are crucial for combating multidrug-resistant TB and extensively drug-resistant TB.
Area of Science:
- Microbiology
- Public Health
- Genetics
Background:
- Multidrug resistance (MDR) and extensive drug resistance (XDR) in tuberculosis (TB) present significant challenges in patient treatment and public health.
- Understanding the mechanisms and genetic factors underlying drug resistance is of critical academic and clinical importance.
Purpose of the Study:
- To review the causes and types of drug resistance in tuberculosis.
- To emphasize the importance of diagnosing drug-resistant tuberculosis.
- To highlight the role of global initiatives in combating drug-resistant TB.
Main Methods:
- Literature review of factors contributing to drug resistance in tuberculosis.
- Categorization of different types of drug resistance (primary, acquired, initial, transitional, natural).
- Analysis of diagnostic importance and mismanagement consequences.
Main Results:
- Causes of drug resistance are multifactorial, including biological, patient, disease, and iatrogenic factors.
- Mismanagement of MDR-TB can escalate to XDR-TB.
- Global strategies and guidelines are essential for National TB Control Programmes.
Conclusions:
- Effective management and diagnosis of drug-resistant tuberculosis are critical to prevent the spread of MDR-TB and XDR-TB.
- Adherence to guidelines from initiatives like the Stop TB Strategy and WHO Global Task Force is vital for national control programs.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

01:30Development of Antibiotic Resistance
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...
01:25Mechanism of Antibiotic Resistance in MRSA
Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
01:26Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
