This systematic review evaluates interventions in preclinical studies for their neuroprotective effects against PVL, highlighting stem cells, erythropoietin, and melatonin as potential therapies with promising outcomes. With most interventions showing only partial efficacy, it is suggested that future research should focus on combination treatments and personalized approaches tailored to different subgroups of preterm neonates.
Introduction Periventricular leukomalacia (PVL) is a result of various antenatal, intrapartum, or postnatal insults to the developing brain and is an important harbinger of cerebral palsy in preterm neonates. There is no proven therapy for PVL. This calls for appraisal of targeted therapies that have been investigated in animal models to evaluate their relevance in a clinical research context. Areas covered This systematic review identifies interventions that were evaluated in preclinical studies for neuroprotective efficacy against PVL. We identified 142 studies evaluating various interventions in PVL animal models (search method is detailed in section 2). Expert opinion Interventions that have yielded significant results in preclinical research, and that have been evaluated in a limited number of clinical trials include stem cells, erythropoietin, and melatonin. Many other therapeutic modalities evaluated in preclinical studies have been identified, but more data on their neuroprotective potential in PVL must be garnered before they can be considered for clinical trials. Because most of the tested interventions had only a partial efficacy, a combination of interventions that could be synergistic should be investigated in future preclinical studies. Furthermore, since the nature and pattern of perinatal insults to preterm brain predisposing it to PVL are substantially variable, individualized approaches for the choice of appropriate neuroprotective interventions tailored to different subgroups of preterm neonates should be explored.
