Phototherapy and plasma immunoreactive prostaglandin A values. Its effect in premature infants
Insights
Phototherapy significantly lowers plasma prostaglandin A (iPGA) levels in premature infants. This treatment also aids in the closure of patent ductus arteriosus in newborns.
Area of Science:
- Neonatal Medicine
- Pediatric Cardiology
- Biochemistry
Background:
- Premature infants often experience conditions like patent ductus arteriosus (PDA).
- Prostaglandin A (PGA) plays a role in maintaining ductal patency.
- Elevated plasma immunoreactive prostaglandin A (iPGA) levels have been observed in premature infants with PDA.
Purpose of the Study:
- To investigate the effect of phototherapy on plasma iPGA levels in premature infants.
- To determine if phototherapy influences the closure of PDA in premature infants.
Main Methods:
- Plasma iPGA levels were measured in 14 premature infants before and after 48 hours of phototherapy.
- A control group of six age-matched premature infants was included for comparison.
- Infants with clinically apparent PDA were specifically monitored.
Main Results:
- Infants receiving phototherapy showed significantly lower iPGA values compared to controls.
- Premature infants with PDA had significantly elevated iPGA levels compared to controls.
- Following phototherapy, these infants experienced a significant decrease in iPGA levels, and PDA closure occurred spontaneously in all four cases.
Conclusions:
- Phototherapy is an effective method for reducing plasma iPGA levels in premature infants.
- Phototherapy may contribute to the spontaneous closure of patent ductus arteriosus in premature infants by modulating prostaglandin levels.
Abstract:
Plasma immunoreactive prostaglandin A (iPGA) values were determined for 14 premature infants before and after 48 hours of phototherapy and in a control group of six age-matched premature infants. At 4 to 8 days of life, the infants who had received phototherapy for 48 hours had significantly lower iPGA values compared with controls. At 2 to 3 days of life, four infants with a clinically apparent patent ductus arteriosus were found to have significantly elevated iPGA values compared with controls. After 48 hours of phototherapy, these infants likewise had a significant decrease in iPGA values compared with controls; in all four infants, the ductus closed spontaneously. Phototherapy is an effective method for decreasing plasma iPGA values in premature infants.
