Summary
A rescue course of antenatal corticosteroids may improve outcomes for twins born before 34 weeks gestation. This intervention reduced mechanical ventilation days and retinopathy of prematurity incidence in twin pregnancies.
Area of Science:
- Perinatology
- Neonatology
- Maternal-Fetal Medicine
Background:
- Antenatal corticosteroids are crucial for fetal lung maturation.
- The efficacy of a rescue course in twin pregnancies is not well-established.
Purpose of the Study:
- To evaluate the effectiveness of a rescue course of antenatal corticosteroids in twin pregnancies.
Main Methods:
- Retrospective cohort study comparing neonatal outcomes.
- Included twins born between 24 and 34 weeks gestation.
- Analyzed outcomes based on exposure to one vs. two courses of corticosteroids, adjusting for twin correlation.
Main Results:
- Rescue corticosteroids were linked to significantly fewer days of mechanical ventilation and reduced need for supplemental oxygen.
- Lower incidence of prolonged mechanical ventilation or death, and reduced retinopathy of prematurity observed.
- No significant difference in respiratory distress syndrome, birth weight, or head circumference.
Conclusions:
- Rescue antenatal corticosteroids may offer benefits for neonatal outcomes in twins born preterm.
- Further research is recommended to confirm these findings in twin pregnancies.

01:21Drugs 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),...
01:25Antiasthma 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...

01:26COPD: 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...
01:23Upper 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...

01:29Drugs 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...
01:22Drug Delivery: Miscellaneous Routes
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs through the...
