NCT ID: NCT00005556 Completed - Blood Disease Clinical Trials

Retention of Bone Marrow Donors in a National Registry

Start date: May 1997
Phase: N/A

NCT ID: NCT00005541 Completed - Iron Overload Clinical Trials

Hemochromatosis and Iron Overload Screening Study (HEIRS)

Start date: January 2000
Phase: N/A
Study type: Observational

NCT ID: NCT00005467 Completed - Anemia, Sickle Cell Clinical Trials

Indices of Severity and Prognosis for Sickle Cell Disease

Start date: January 1990
Phase: N/A
Study type: Observational

To develop a clinical severity index that could prospectively identify sickle cell disease patients who were at high risk for a turbulent clinical course and a poor prognosis.

NCT ID: NCT00005438 Completed - Anemia, Sickle Cell Clinical Trials

Neuropsychological Studies of Children With Sickle Cell

Start date: February 1993
Phase: N/A

Start date: January 1988
Phase: N/A
Study type: Observational

To continue studies on the two major neurological complications of sickle cell disease (SCD): namely, stroke and chronic encephalopathy.
