Brief Summary:
This is an international prospective registry of patients with Alpha thalassemia to understand the natural history of the disease and the outcomes of fetal therapies, with the overall goal of improving the prenatal management of patients with Alpha thalassemia.

Condition or disease
Alpha-Thalassemia Alpha Thalassemia Major Alpha Thalassemia Minor

Detailed Description:

The aim of this registry is to prospectively and retrospectively collect data on patients who are diagnosed with alpha thalassemia major and other alpha thalassemia mutations. Data collected will be used to:

  1. Identify patient outcomes of therapies.
  2. Improve clinical management of patients with ATM.
  3. Improve medical decision making.
  4. Improve quality of care.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 500 participants
Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 30 Years
Official Title: International Prospective Registry of Patients With Alpha Thalassemia
Actual Study Start Date : January 2017
Estimated Primary Completion Date : January 2027
Estimated Study Completion Date : January 2037





Primary Outcome Measures :
  1. Survival to birth [ Time Frame: 6 months ]
    Number of fetuses diagnosed with alpha thalassemia who survive to birth, compared to number of fetuses diagnosed with alpha thalassemia who have fetal demise or are terminated in utero. This is measured in number of fetuses alive at birth divided by number of all fetuses.

  2. Vineland-3 Adaptive Behavior Scale [ Time Frame: 10-15 years ]
    Results of neurodevelopmental testing using the Vineland Adaptive Behavior Scale version 3. The Vineland-3 scoring system is based on scores for three specific adaptive behavior domains: Communication, Daily Living Skills, and Socialization. The domain scores are expressed as standard scores with a mean of 100 and standard deviation of 15.


Secondary Outcome Measures :
  1. Gestational age at birth [ Time Frame: 6 months ]
    Gestational age of the child at birth. This is measured in weeks.

  2. Mechanical ventilation [ Time Frame: 1 year ]
    Duration (if any) of requiring mechanical ventilation after birth. This is measured in days.

  3. Length of hospitalization [ Time Frame: 6 months-1 year ]
    Duration of the child's hospitalization after birth. This is measured in days.

  4. Resolution of hydrops [ Time Frame: 6 months ]
    Evaluate whether receiving fetal therapy leads hydrops fetalis to resolve. This is measured by ultrasound findings.
