General information about the trial
|
|||
Main objective of the trial |
Aims of the proposed study 1) to investigate morphological and biochemical parameters of skeletal mus-cle systematically, to identify hematopoietic progenitor cells (CD34, CD133) as well as to measure baseline Frataxin expression in skeletal muscle (specimen) of FRDA patients. 2) to measure numbers of circulating CD34 and CD133 hematopoietic progenitor cells in peripheral blood of FRDA patients in response to rhuEPO treatment; 3) to study effects of rhuEPO treatment on Frataxin expression, numbers of CD34 and CD133 hematopoietic progenitor cells, satellite cells, capillary density and respiratory chain complex activi-ties of skeletal muscle tissue obtained by re-biopsy. 4) to identify changes in muscle energy metabolism (in-vivo marker) in skeletal muscle of rhuEPO treated FRDA patients applying magnetic resonance spectros-copy at baseline and study endpoint.
