Abstract

Insights

Adding amikacin to standard tuberculosis treatment did not shorten the time to sputum smear conversion in patients. This suggests amikacin may not improve early infectiousness during initial treatment for tuberculosis.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Pharmacology

Background:

  • Tuberculosis (TB) remains a significant global health challenge.
  • Sputum conversion is a key indicator of treatment efficacy and reduced contagiousness.
  • Amikacin is an aminoglycoside antibiotic with activity against Mycobacterium tuberculosis.

Purpose of the Study:

  • To assess the impact of amikacin on sputum smear conversion time in patients with smear-positive pulmonary tuberculosis.
  • To evaluate if adding amikacin to standard treatment shortens the period of infectiousness.

Main Methods:

  • A single-center observational cohort study was conducted between 2012 and 2013.
  • Patients received either standard treatment (ST) or standard treatment plus amikacin (STamK) for seven days.
  • Time to sputum smear conversion was the primary outcome measured.

Main Results:

  • The median time to sputum smear conversion was 26.5 days for the ST group (n=30) and 48 days for the STamK group (n=15), with no statistically significant difference (P=0.76).
  • Time to negative culture results was also analyzed, showing a median of 47.5 days for ST and 40 days for STamK, though data was available for fewer patients.
  • The study included 45 patients in total.

Conclusions:

  • The addition of amikacin to standard tuberculosis treatment did not appear to influence the time to sputum smear conversion.
  • The findings suggest that amikacin may not significantly reduce the period of contagiousness in the initial phase of TB treatment.
  • Further research with larger sample sizes is warranted to confirm these observations.

Pulmonary Tuberculosis V

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...

Pulmonary 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...

Estimation of k and VD of Aminoglycosides01:20

Estimation of k and VD of Aminoglycosides

Aminoglycosides are a class of antibiotics used to treat various bacterial infections. Clinicians must determine the elimination rate constant (k) and volume of distribution (VD) to optimize therapeutic efficacy and minimize toxicity. The k value represents the rate at which the drug is removed from the body, and the VD reflects the degree to which the drug distributes into body tissues. Accurately estimating these parameters allows healthcare professionals to tailor drug dosing to individual...

Pulmonary Tuberculosis I01:29

Pulmonary 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.

Pulmonary Tuberculosis II

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...

Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...
