The use of health-related quality of life scales as outcome measures in clinical trials is increasing. Although such measures have been validated in adults with Friedreich ataxia, they have not been studied in children with this disorder. The health-related quality of life of children with Friedreich ataxia was assessed using the PedsQL 4.0 Generic Core Module and Multidimensional Fatigue Scale. The scores from the Friedreich ataxia cohort were compared to those of control groups (children without a chronic disease). Minimal missing responses support the feasibility of using the PedsQL 4.0 in the Friedreich ataxia population. The scales demonstrated internal consistency, and concordance was observed between child and proxy scores. Children with Friedreich ataxia and their proxies reported lower health-related quality of life than did controls in the Core and Fatigue scales. A modest relationship was seen between markers of disease status and health-related quality of life, providing support for the idea that children with Friedreich ataxia have a lower health-related quality of life than those without a chronic disease. Additional studies are needed to examine the relationship between health-related quality of life and disease markers and to further establish the validity of the PedsQL 4.0 in this population.

Deferiprone (L1) was originally designed, synthesised and screened in vitro and in vivo in 1981 by Kontoghiorghes G. J. following his discovery of the novel alpha-ketohydroxypyridine class of iron chelators (1978-1981), which were intended for clinical use. The journey through the years for the treatment of thalassaemia with L1 has been a very difficult one with an intriguing turn of events, which continue until today. Despite many complications, such as the extensive use of L1 suboptimal dose protocols, the aim of chelation therapy-namely, the complete removal of excess iron in thalassaemia major patients, has been achieved in most cases following the introduction of specific L1 and L1/deferoxamine combinations. Many such patients continue to maintain normal iron stores. Thalassemia has changed from a fatal to chronic disease; also thanks to L1 therapy and thalassaemia patients are active professional members in all sectors of society, have their own families with children and grandchildren and their lifespan is approaching that of normal individuals. No changes in the low toxicity profile of L1 have been observed in more than 30 years of clinical use and prophylaxis against the low incidence of agranulocytosis is maintained using mandatory monitoring of weekly white blood cells' count. Thousands of thalassaemia patients are still denied the cardioprotective and other beneficial effects of L1 therapy. The safety of L1 in thalassaemia and other non-iron loaded diseases resulted in its selection as one of the leading therapeutics for the treatment of Friedreich's ataxia, pantothenate kinase-associated neurodegeneration and other similar cases. There are also increasing prospects for the application of L1 as a main, alternative or adjuvant therapy in many pathological conditions including cancer, infectious diseases and as a general antioxidant for diseases related to free radical pathology.
