Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

750
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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

606
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

1.2K
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 IV

624
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...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids01:25

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

1.9K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents01:29

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

655
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Summary

Corticosteroids significantly reduce short-term deaths from tuberculous meningitis (TB) but may not impact long-term survival or severe disability. Further research is needed for HIV-positive individuals.

Area of Science:

  • Infectious Diseases
  • Neurology
  • Clinical Trials

Background:

  • Tuberculous meningitis (TB) is a severe form of tuberculosis affecting the brain and spinal cord.
  • It is associated with high mortality and disability rates.
  • The role of corticosteroids in treating TB meningitis has been debated.

Purpose of the Study:

  • To evaluate the effectiveness of corticosteroids as an add-on therapy for tuberculous meningitis.
  • To assess the impact on mortality and severe disability in patients with TB meningitis.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials.
  • Searched multiple databases (Cochrane, MEDLINE, EMBASE, LILACS) and contacted researchers.
  • Included trials comparing corticosteroid plus antituberculous treatment versus antituberculous treatment alone.

Main Results:

  • Corticosteroids reduced short-term mortality by nearly 25% (high-quality evidence).
  • No significant effect was observed on severe neurological disability (low-quality evidence).
  • Long-term mortality benefits were not apparent, and adverse events were similar between groups.

Conclusions:

  • Corticosteroids are effective in reducing short-term mortality from tuberculous meningitis.
  • The effect on severe disability is uncertain, but the potential harm is likely outweighed by mortality benefits.
  • More research is needed to confirm benefits in HIV-positive individuals due to small sample sizes.
