Insights
Activated factor VII (aFVII) combined with fresh frozen plasma (FFP) showed promise in limiting intraventricular hemorrhage (IVH) progression in very low birth weight infants. Further research is needed to confirm these findings.
Area of Science:
- Neonatal care
- Pediatric neurology
- Hematology
Background:
- Intraventricular hemorrhage (IVH) is a significant complication in very low birth weight (VLBW) infants.
- Activated factor VII (aFVII) can activate the coagulation cascade and potentially limit bleeding, including IVH.
Purpose of the Study:
- To compare the efficacy of fresh frozen plasma (FFP) alone versus FFP combined with aFVII in managing IVH progression in VLBW infants.
Main Methods:
- Retrospective observational study comparing VLBW infants with IVH progression.
- Treatment groups: FFP alone (control) vs. FFP + aFVII.
- Cranial ultrasonography used for monitoring IVH extent.
Main Results:
- The aFVII + FFP group showed significantly less IVH progression (p<0.01).
- Fewer deaths and cases of posthemorrhagic hydrocephalus in the aFVII group.
- No significant differences in other outcomes or 2-year follow-up results.
Conclusions:
- Activated factor VII (aFVII) may be a potential therapeutic candidate for limiting intraventricular hemorrhage (IVH) progression in VLBW infants.
- A prospective randomized trial is recommended to validate these findings.
Abstract:
Backround Intraventricular hemorrhage (IVH) remains a dangerous and frequent complication in very low birth weight (VLBW) infants. Activated factor VII (aFVII) activates the coagulation cascade and is a potential tool for stopping active bleeding, including limiting the extent of an IVH. This retrospective treatment observation compared data for infants with IVH progression treated with fresh frozen plasma (FFP) alone or with a combination of FFP and aFVII. Methods/Intervention All infants were subject to cranial ultrasonography at least twice daily. When an IVH was detected, treatment with FFP (5-20 ml/kg every 4-6 h) was commenced and the parents were informed. If the parents endorsed aFVII treatment and the IVH showed progress, aFVII (30-50 µg/kg body weight 4-6 times within 16-24 h) was given. Otherwise, infants were treated with FFP only. We compared the course of IVH between the aFVII+FFP treated infants and a control group (FFP only). Results 35 patients throughout were included in the analysis (17 control and 18 aFVII group). Demographic data was not different between groups. The progress of IVH was significantly less in the aFVII group (p<0.01). During the hospital stay, 2 of the infants in the aFVII group died compared to 4 in the control group. A posthemorrhagic hydrocephalus developed in 3 aFVII and 6 control infants. All other outcome parameters and follow-up-results 2 years after treatment did not differ significantly. Conclusion These data show that in the case of a progressing IVH, aFVII may be a candidate for limiting its extent. A prospective randomized trial is warranted.
