Insights

Thalidomide, an immunomodulatory drug, was found safe and well-tolerated as an add-on treatment for children with tuberculous meningitis. It reduced inflammation and showed promising clinical outcomes, warranting further study.

Area of Science:

  • Pediatric Infectious Diseases
  • Neuroimmunology
  • Pharmacology

Background:

  • Tuberculous meningitis (TBM) is a severe infection requiring multifaceted treatment.
  • Adjunct therapies are explored to improve outcomes in TBM, particularly for managing inflammation.

Purpose of the Study:

  • To evaluate the safety and tolerability of thalidomide as an adjunct therapy in children with stage 2 TBM.
  • To assess the impact of thalidomide on inflammatory markers and clinical outcomes.

Main Methods:

  • A dose-escalating study involving 15 children with TBM receiving thalidomide for 28 days alongside standard anti-TB therapy and corticosteroids.
  • Clinical and laboratory assessments, including cerebrospinal fluid tumor necrosis factor-alpha levels, were performed.
  • Dosages ranged from 6 to 24 mg/kg/day administered via nasogastric tube.

Main Results:

  • Thalidomide was safe and well-tolerated, with only transient skin rashes as possible adverse events.
  • Significant reduction in cerebrospinal fluid tumor necrosis factor-alpha levels observed.
  • Improved clinical outcomes and neurologic imaging compared to historical controls.

Conclusions:

  • Thalidomide shows potential as an anti-inflammatory agent in pediatric TBM.
  • The drug is safe and well-tolerated in this patient population.
  • Results support further investigation in a randomized controlled trial.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...

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.

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

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 Disease...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

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...
