Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids01:21

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

692
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...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

2.1K
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...

Desensitization and Tachyphylaxis01:20

Desensitization and Tachyphylaxis

3.4K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

Summary

Betamethasone corticosteroid injections (CSIs) for trigger finger have a higher failure rate and shorter time to failure compared to triamcinolone CSIs. Triamcinolone is more effective for primary trigger finger treatment.

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Pharmacology

Background:

  • Trigger finger, a common condition, often requires corticosteroid injections (CSIs) for treatment.
  • The choice of corticosteroid may influence treatment outcomes.
  • Comparing different corticosteroids is crucial for optimizing patient care.

Purpose of the Study:

  • To compare the failure rates of primary trigger finger CSIs using triamcinolone versus betamethasone.
  • To evaluate the time to failure for each corticosteroid type.

Main Methods:

  • Retrospective cohort study of primary trigger finger CSIs.
  • Two groups: triamcinolone (June 2022-Jan 2023) and betamethasone (June 2023-Jan 2024).
  • Failure defined as reintervention (repeat CSI or surgery) within one year.

Main Results:

  • Triamcinolone cohort: 16.5% failure rate within 1 year.
  • Betamethasone cohort: 34.9% failure rate within 1 year.
  • Betamethasone group had significantly higher failure rates and shorter time to failure (167 days vs. 273 days).

Conclusions:

  • Triamcinolone CSIs demonstrate a lower failure rate for primary trigger finger treatment compared to betamethasone.
  • Betamethasone CSIs are associated with a quicker return of trigger finger symptoms requiring reintervention.
  • Triamcinolone may be a more effective choice for initial CSI treatment of trigger finger.
