Update of the Spanish Registry of Haemoglobinopathies in Children and Adults.

Background and objective: Patients with thalassaemia major (TM) and sickle cell disease (SCD) in Spain have been counted since the creation of the Spanish registry of haemoglobinopathies (REHem). The objective of this paper is to update the published data after the increase in cases due to the inclusion of adults and introduction of new-born screening in almost the whole country. Material and methods: An observational, descriptive, multicentre and ambispective study that included patients with haemoglobinopathies registered in the REHem, started in January 2014 and followed up annually. The data presented correspond until December 31, 2017. Results: Nine hundred and fifty-nine patients were collected. There were 75 cases of thalassaemia (62 TM), 826 of ECF and 58 of other types of haemoglobinopathies. The main diagnostic reason in the TM cohort was anaemia symptoms (70.6%), with a mean age at diagnosis of.7 years; in the SCD cohort it was neonatal screening (33.1%), with a mean age at diagnosis of 2.7 years; 26 patients with TM (41.9%) and 30 with SCD (3.6%) underwent a transplant. There were 2 deaths (3.2%) with TM and 19 (2.3%) with SCD. Overall survival was 96.7% in the TM and 97.5% in the SCD cases at 15 years. Conclusions: Since the previous publication and after the diffusion of new-born screening, the most frequent diagnostic method, to the majority of autonomous regions, and the inclusion of adult patients to the registry, the REHem has increased by more than 240 cases, reaching a total of 959 records.
