Insights
Systematic steroid use in very low birth weight (VLBW) infants is linked to serious short-term side effects, including hypertrophic cardiomyopathy and thrombus formation. These risks necessitate careful consideration during steroid administration in VLBW neonates.
Area of Science:
- Neonatal Medicine
- Pediatric Cardiology
- Neonatal Intensive Care
Background:
- Systematic steroid administration is employed in very low birth weight (VLBW) infants.
- Potential adverse events associated with steroid use require thorough investigation.
Purpose of the Study:
- To evaluate the incidence of cardiac and metabolic adverse events in VLBW infants receiving systematic steroids.
- To identify risks associated with steroid therapy in this vulnerable population.
Main Methods:
- A prospective single-center audit was conducted.
- Included VLBW infants (<1,500 g) admitted to the neonatal intensive care unit.
- Data collected on steroid use, indications, and adverse events.
Main Results:
- Steroid use was associated with significantly lower birth weight, gestational age, and Apgar scores.
- Increased incidence of hypertrophic cardiomyopathy, thrombus formation, hyperglycemia, hypernatremia, and sepsis/infections in the steroid group.
- Mortality rate was higher in infants receiving steroids (OR: 9.6, p=0.02).
Conclusions:
- Systematic steroid administration in VLBW infants is significantly associated with severe short-term adverse events.
- Hypertrophic cardiomyopathy and thrombus formation are critical concerns.
- These complications must be weighed against the benefits when prescribing steroids to VLBW infants.
Background And Study Purpose:
To assess the incidence of cardiac and metabolic adverse events in very low birth weight (VLBW) infants receiving systematic steroids.
Patients And Methods:
Prospective single centre audit in VLBW infants (<1,500 g) at the neonatal intensive care unit at the University Children's Hospital of Saarland, Germany.
Results:
A total of 72 VLBW infants (38 female) were included in this report (mean birth weight: 967 ± 338 g; range: 320-1490 g). Birth weight, gestational age and Apgar scores were significantly lower in the steroid group (p <0.01). Mortality rate was 8/72 (7/34 in the steroid treated vs nontreated 1/38; odds ratio [OR]: 9.6; 95% confidence interval [CI]: 1.1-82.6 p = 0.02). In 34/72 infants, steroids were given (22 hydrocortisone alone; 12 combination of hydrocortisone and dexamethasone). The most common indication for use of steroids was respiratory distress syndrome (RDS) and respiratory insufficiency (30/34). Adverse events that occurred more often in the steroid group included hypertrophic cardiomyopathy (14/34 vs 0/38; p <0.001); thrombus formation (8/34 vs 1/38; OR: 11.4; 95% CI: 1.3-96.6; p <0.05), hyperglycaemia (27/34 vs 3/38; OR: 45.0; 95% CI: 10.6-190.4; p <0.01), hypernatraemia (15/34 vs 7/38; OR: 3.5; 95% CI: 1.2-10.1; p <0.05), and sepsis/infections (8/34 vs 1/38; OR: 11.4; 95% CI: 1.3-96.6; p <0.05). No significant differences were seen between hydrocortisone alone and the combination of hydrocortisone with dexamethasone. Birth weight and severity of RDS were predictors of steroid use (p <0.01).
Conclusions:
The use of steroids was significantly associated with severe short-term adverse events - most importantly hypertrophic cardiomyopathy and thrombus formation. These complications must be taken into consideration when administering steroids to VLBW infants.

This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
