Detailed Description:

Acquired sensorineural hearing loss is characterized by a loss of functioning hair cells in the Organ of Corti, with greater hair cell loss correlating with more severe hearing impairment. Children with sensorineural hearing loss experience difficulty developing normal language which usually leads to poor academic and social development. Currently, there are no reparative therapeutic options available, and treatments are designed to augment the diminished function of the injured Organ of Corti.

Pre-clinical data suggest progenitor cell infusions may enhance intrinsic repair mechanisms in the Organ of Corti which may restore hair cells. This treatment could ultimately lead to hearing improvement. Human umbilical cord blood (hUCB) is an available, autologous, stored progenitor cell population available for potential therapeutic use. The primary objective of this study is to determine the safety of autologous hUCB infusion in children with acquired hearing loss. The secondary objective is to determine if functional, physiologic and anatomic outcomes are improved following hUCB treatment in this patient population.

  Eligibility

Ages Eligible for Study:   6 Weeks to 18 Months
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Evidence of a moderate to profound sensorineural hearing loss.
  2. Normally shaped cochlea, as determined by MRI.
  3. The loss must be considered acquired, NOT syndromic.
  4. The patient must be fitted for hearing aids of the detection of the loss.
  5. Enrollment in a parent/child intervention program.
  6. Between 6 weeks and 18 months of age at the time of cord blood infusion.
  7. Ability of child and caregiver to travel to Houston for treatment and all follow-up appointments. (Patient's family is responsible for the cost of travel to and lodging in Houston).

Exclusion Criteria:

  1. Inability to obtain pertinent medical records.

  2. Known history or

    • Recently treated ear or other infection.
    • Renal disease.
    • Hepatic disease.
    • Malignancy.
    • HIV.

    • Evidence of an extensive stroke (> 100ml).
    • Pneumonia, or chronic lung disease.
  3. hUCB sample contamination.
  4. Participation in a concurrent intervention study.
  5. Desire for organ donation in the event of death.
  6. Unwillingness or inability to stay 4 days following hUCB infusion, and to return for the one month, six month and one year follow-up visits.
  7. Presence of a cochlear implant device.
  8. Evidence of a syndrome.
  9. Positive test for genetic hearing loss.
  10. Evidence of conductive hearing loss.
  11. Documented evidence of recurrent middle ear infections (> 5/year).
  12. Otitis media at the time of examination.
  13. Mild sensorineural hearing loss.
  14. Over 18 months at the time of infusion.
