Summary
Totally drug-resistant tuberculosis (TDR-TB) poses a significant global health challenge due to limited treatment options and high fatality rates. Research explores novel drugs and adjunct therapies to combat evolving drug resistance in Mycobacterium tuberculosis.
Area of Science:
- * Infectious Diseases
- * Microbiology
- * Pharmacology
Background:
- * Totally drug-resistant tuberculosis (TDR-TB), defined as resistance to all first- and second-line drugs, has emerged globally.
- * Mycobacterium tuberculosis acquires resistance through sequential mutations driven by suboptimal treatment regimens.
- * High fatality rates and the impact of comorbidities like HIV and diabetes complicate TDR-TB management.
Purpose of the Study:
- * To review the current landscape of drug resistance in tuberculosis (TB).
- * To explore emerging and repurposed therapeutic strategies for TDR-TB.
- * To discuss the potential of adjunct therapies for improving clinical outcomes.
Main Methods:
- * Comprehensive literature review of drug resistance mechanisms in Mycobacterium tuberculosis.
- * Analysis of current and late-stage clinical trial data for novel anti-TB drug candidates.
- * Evaluation of adjunct therapeutic approaches, including vaccines and repurposed drugs.
Main Results:
- * Emergence of TDR-TB cases worldwide necessitates urgent therapeutic innovation.
- * Several novel drug candidates (delamanid, bedaquiline, SQ109, sutezolid) show promise.
- * Adjunct therapies may enhance the efficacy of standard chemotherapy for drug-resistant TB.
Conclusions:
- * Drug resistance in TB is an evolving challenge requiring continuous research and development.
- * Novel drugs and repurposed agents offer new hope for treating resistant strains.
- * Combination therapies, including adjunct treatments, are crucial for achieving better clinical outcomes and potentially curing TB.

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...

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.

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...

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:25Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...
