Insights

Antenatal corticosteroids are crucial for improving preterm birth outcomes. While effective for many, further research is needed for specific populations and optimal dosing strategies.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Medicine
  • Public Health

Background:

  • Preterm birth remains a significant public health concern in the United States.
  • Antenatal corticosteroids represent a cornerstone intervention to improve outcomes for preterm infants.
  • The efficacy and safety of this therapy have been studied for over 40 years.

Purpose of the Study:

  • To summarize the accumulated evidence on the efficacy and safety of antenatal corticosteroids.
  • To identify remaining questions and areas for future research regarding antenatal corticosteroid use.
  • To refine the application of antenatal corticosteroids for improved outcomes in at-risk pregnancies.

Main Methods:

  • Review of accumulated evidence on antenatal corticosteroid therapy.
  • Analysis of clinical trial data and observational studies.
  • Synthesis of findings related to efficacy, safety, and specific patient populations.

Main Results:

  • Antenatal corticosteroids are effective for singleton pregnancies between 26 and 34 weeks’ gestation.
  • Efficacy and optimal use in multiple gestations, very early preterm gestations, and IUGR pregnancies require further investigation.
  • Uncertainty persists regarding the duration of effectiveness and the need for repeat or rescue courses.

Conclusions:

  • Antenatal corticosteroids are a vital intervention for improving neonatal outcomes following preterm birth.
  • Further research is essential to optimize the use of antenatal corticosteroids in diverse and complex obstetric scenarios.
  • Refined therapeutic strategies are needed to maximize benefits for all at-risk preterm infants.

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

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...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by anesthetizing...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

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

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 (COX-2),...
