Insights

Hydrocortisone may be a safer alternative to dexamethasone for treating chronic lung disease in preterm infants. Studies show no adverse neurodevelopmental or cardiovascular effects, but more research is needed.

Area of Science:

  • Neonatal Medicine
  • Pediatric Pulmonology
  • Neurodevelopmental Pediatrics

Background:

  • Chronic lung disease (CLD) is a significant issue in preterm infants despite advanced care.
  • Dexamethasone is the primary treatment for CLD, but carries concerning long-term neurodevelopmental risks.
  • Hydrocortisone presents a potential alternative with a potentially better safety profile.

Purpose of the Study:

  • To review existing literature on neonatal hydrocortisone for CLD.
  • To assess long-term neurodevelopmental outcomes associated with hydrocortisone treatment.
  • To evaluate cardiovascular effects and safety compared to dexamethasone.

Main Methods:

  • Systematic review of current literature on hydrocortisone use in neonates with CLD.
  • Analysis of studies focusing on neurodevelopmental assessments (cognitive, motor, brain imaging).
  • Evaluation of cardiovascular stress response data at school age.

Main Results:

  • No adverse neurodevelopmental effects observed with hydrocortisone.
  • No increased incidence of brain abnormalities on MRI.
  • Hypothalamic-pituitary-adrenal axis programming and cardiovascular stress response were comparable to controls.

Conclusions:

  • Hydrocortisone appears to be a safe alternative to dexamethasone for neonatal CLD.
  • Further rigorous double-blind randomized controlled trials are necessary to confirm efficacy and safety.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

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...

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...

Adrenergic Antagonists: Pharmacological Actions of β-Receptor Blockers

β-receptor blockers significantly impact the cardiovascular system by counteracting catecholamine-induced sympathetic responses. These medications decrease heart rate, contractility, and cardiac output, potentially leading to cardiac depression, life-threatening bradycardia, and death. Therapeutically, β-blockers function as mild antihypertensives and are utilized in treating angina pectoris and cardiac arrhythmias. However, nonselective β-blockers inhibit β2-receptors in bronchial smooth...

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),...
