    Benefits of Newborn Screening and Hematopoietic Cell Transplant in Infantile Krabbe Disease.
    (Blood advances, 2022-01-18) Page, Kristin M; Ream, Margie A; Rangarajan, Hemalatha G; Galindo, Rafael; Mian, Ali Y; Ho, Mai-Lan; Provenzale, James; Gustafson, Kathryn E; Rubin, Jennifer; Shenoy, Shalini; Kurtzberg, Joanne
    Infantile Krabbe Disease (IKD) can be treated with hematopoietic cell transplantation (HCT) if done during the first weeks of life before symptoms develop. To facilitate this, newborn screening (NBS) has been instituted in eight U.S. states. An application to add KD to the Recommended NBS Panel (RUSP) is currently under review. In this report, the outcomes of newborns with IKD diagnosed through NBS and treated with HCT are presented. The unique challenges associated with NBS for this disease are discussed including opportunities for earlier diagnosis and streamlining treatment referrals. This is a retrospective review of infants with IKD detected by NBS and referred for HCT. The timing from diagnosis to HCT were examined and both HCT and neurodevelopmental outcomes are described. Six infants were diagnosed and referred for HCT. Neurologic testing before HCT revealed evidence of active IKD in all infants. All underwent HCT between 24-40 days of age, successfully engrafted, and are alive 30-58 months later (median, 47.5 months). All are gaining developmental milestones albeit at a slower pace than unaffected age-matched peers. Gross motor function is most notably affected. NBS for these patients enabled early access to HCT, the only currently available treatment for infants with IKD. All children are alive and have derived developmental and neurologic benefits from timely HCT. Long-term follow up is ongoing. Optimization of HCT and further development of emerging therapies, all of which must be delivered early in life, are expected to further improve outcomes of infants with IKD.

    Effect of Autologous Cord Blood Infusion on Motor Function and Brain Connectivity in Young Children with Cerebral Palsy: A Randomized, Placebo-Controlled Trial.
    (Stem cells translational medicine, 2017-12) Sun, Jessica M; Song, Allen W; Case, Laura E; Mikati, Mohamad A; Gustafson, Kathryn E; Simmons, Ryan; Goldstein, Ricki; Petry, Jodi; McLaughlin, Colleen; Waters-Pick, Barbara; Chen, Lyon W; Wease, Stephen; Blackwell, Beth; Worley, Gordon; Troy, Jesse; Kurtzberg, Joanne
    Cerebral palsy (CP) is a condition affecting young children that causes lifelong disabilities. Umbilical cord blood cells improve motor function in experimental systems via paracrine signaling. After demonstrating safety, we conducted a phase II trial of autologous cord blood (ACB) infusion in children with CP to test whether ACB could improve function (ClinicalTrials.gov, NCT01147653; IND 14360). In this double-blind, placebo-controlled, crossover study of a single intravenous infusion of 1-5 × 107 total nucleated cells per kilogram of ACB, children ages 1 to 6 years with CP were randomly assigned to receive ACB or placebo at baseline, followed by the alternate infusion 1 year later. Motor function and magnetic resonance imaging brain connectivity studies were performed at baseline, 1, and 2 years post-treatment. The primary endpoint was change in motor function 1 year after baseline infusion. Additional analyses were performed at 2 years. Sixty-three children (median age 2.1 years) were randomized to treatment (n = 32) or placebo (n = 31) at baseline. Although there was no difference in mean change in Gross Motor Function Measure-66 (GMFM-66) scores at 1 year between placebo and treated groups, a dosing effect was identified. In an analysis 1 year post-ACB treatment, those who received doses ≥2 × 107 /kg demonstrated significantly greater increases in GMFM-66 scores above those predicted by age and severity, as well as in Peabody Developmental Motor Scales-2 Gross Motor Quotient scores and normalized brain connectivity. Results of this study suggest that appropriately dosed ACB infusion improves brain connectivity and gross motor function in young children with CP. Stem Cells Translational Medicine 2017;6:2071-2078.

    Feasibility of autologous cord blood cells for infants with hypoxic-ischemic encephalopathy.
    (The Journal of pediatrics, 2014-05) Cotten, C Michael; Murtha, Amy P; Goldberg, Ronald N; Grotegut, Chad A; Smith, P Brian; Goldstein, Ricki F; Fisher, Kimberley A; Gustafson, Kathryn E; Waters-Pick, Barbara; Swamy, Geeta K; Rattray, Benjamin; Tan, Siddhartha; Kurtzberg, Joanne

    Objective

    To assess feasibility and safety of providing autologous umbilical cord blood (UCB) cells to neonates with hypoxic-ischemic encephalopathy (HIE).

    Study design

    We enrolled infants in the intensive care nursery who were cooled for HIE and had available UCB in an open-label study of non-cyropreserved autologous volume- and red blood cell-reduced UCB cells (up to 4 doses adjusted for volume and red blood cell content, 1-5 × 10(7) cells/dose). We recorded UCB collection and cell infusion characteristics, and pre- and post-infusion vital signs. As exploratory analyses, we compared cell recipients' hospital outcomes (mortality, oral feeds at discharge) and 1-year survival with Bayley Scales of Infant and Toddler Development, 3rd edition scores ≥85 in 3 domains (cognitive, language, and motor development) with cooled infants who did not have available cells.

    Results

    Twenty-three infants were cooled and received cells. Median collection and infusion volumes were 36 and 4.3 mL. Vital signs including oxygen saturation were similar before and after infusions in the first 48 postnatal hours. Cell recipients and concurrent cooled infants had similar hospital outcomes. Thirteen of 18 (74%) cell recipients and 19 of 46 (41%) concurrent cooled infants with known 1-year outcomes survived with scores >85.

    Conclusions

    Collection, preparation, and infusion of fresh autologous UCB cells for use in infants with HIE is feasible. A randomized double-blind study is needed.
