Oral propranolol in early stages of retinopathy of prematurity
Insights
Oral propranolol effectively treats early retinopathy of prematurity (ROP) in premature infants, preventing disease progression and reducing the need for laser or bevacizumab interventions without significant side effects.
Area of Science:
- Neonatal ophthalmology
- Pharmacology
- Perinatal medicine
Background:
- Retinopathy of prematurity (ROP) is a leading cause of visual impairment in premature infants.
- Early-stage ROP (stages 2-3, zones II-III) requires effective management to prevent severe visual outcomes.
- Current treatments may involve invasive procedures with potential complications.
Purpose of the Study:
- To evaluate the efficacy and safety of oral propranolol for treating early-stage retinopathy of prematurity (ROP) in very low birth weight (VLBW) infants.
- To determine if propranolol can prevent ROP progression and decrease the need for rescue therapies.
Main Methods:
- A cohort of VLBW infants with ROP stages 2-3, zones II-III received oral propranolol (0.5 mg/kg/dose q8h).
- Treatment continued until ROP regression, with monitoring for side effects.
- A historic control group with similar ROP characteristics was used for comparison.
Main Results:
- 90% of infants treated with propranolol avoided laser or bevacizumab intervention, compared to 51.8% in the control group (P<0.005).
- No significant differences in gestational age, birth weight, or gender were observed between groups.
- No adverse events such as bradycardia, hypotension, or hypoglycemia were reported during propranolol treatment.
Conclusions:
- Oral propranolol demonstrates potential in preventing the progression of early-stage ROP in VLBW infants.
- Propranolol treatment significantly reduced the requirement for invasive rescue therapies like laser or bevacizumab.
- The treatment was well-tolerated, with no significant side effects observed.
Objective:
To assess the effect of oral propranolol on the progression of early stages of retinopathy of prematurity (ROP) in very low birth weight (VLBW) infants.
Methods:
We analyzed VLBW infants with ROP (stages 2-3, zones II-III). Newborns received oral propranolol (0.5 mg/kg/dose q8h), and were monitored throughout the treatment period for possible side effects. Propranolol was administered until regression of ROP. A historic control group of patients with equivalent ROP was used. We compared characteristics of both groups and the progression of retinopathy.
Results:
Forty-seven newborns were included, 20 in the propranolol group and 27 in the control group. There were no significant differences in gestational age, birthweight or gender. The mean duration of treatment with propranolol was 58.2±17.6 days. Most patients started treatment with stage 2 disease (65.0%), and had zone III involvement (55.0%). In the treated group, 90.0% (18/20) of patients did not require intervention with laser or bevacizumab, compared to 51.8% in the control group (P<0.005). No cases of bradycardia, hypotension or hypoglycemia were observed.
Conclusions:
Oral propranolol in early stages of ROP could prevent disease progression and reduce the need for invasive rescue therapy with laser or bevacizumab. No significant side effects were reported.
