“The authors regret that the above article contained a minor error on page 2: the twenty first line of the right-hand column should read, “In normal red cells the ratio between reduced and oxidized glutathione (GSSG)

is usually about 100:1” as opposed to “In normal red cells the ratio between oxidized and reduced glutathione (GSSH) is 100:1”. “
“Sickle cell disease (SCD), the most common inherited red blood cell (RBC) disorder, affects individuals of African, Mediterranean, and Asian descent and manifests as haemolysis and vaso-occlusion [1]. Patients experience a

spectrum of disease symptoms and complications, including periods of acute pain (vaso-occlusive episodes [VOE]), chronic pain, multi-organ injury, reduced quality of life, and a shortened lifespan [1] and [2]. Worldwide it is estimated that over 200,000 children affected with SCD are born every year, primarily in selleck chemical sub-Saharan Africa (180,000 births per year) [3] and [4]. Approximately 2000 children in the US [5] are born with SCD each year, with a disease incidence of 1 in 2474 live births (newborn screening data 1990–1999) [6]; the estimated US prevalence ranges from 70,000–140,000 [7] and [8]. Among individuals with the homozygous sickle haemoglobin mutation (HbSS) living in first-world countries, the estimated mean life expectancy Tacrolimus (FK506) is 39 years [8], which has improved significantly over the last few decades. Increased overall survival of paediatric patients with SCD [9] (Fig. 1) can be attributed to the landmark Prophylactic Penicillin Study (PROPS; 1986), [10] which demonstrated that the use of prophylactic

penicillin could prevent life-threatening infections in affected children. Thus, universal newborn screening became standard practice in the US in the late 1990s and in the United Kingdom in the early 2000′s [10], [11] and [12], enabling early diagnosis and patient management. The introduction of a pneumococcal conjugate vaccine also significantly contributes to decreased SCD mortality in children younger than 10 years of age [12] and [13]. However, in low-resource countries, more than 50% of children younger than 5 years of age die due to complications of SCD [14]. Because more than 98% of children with milder forms of SCD in high-resource countries are living into adulthood, SCD is now a chronic condition requiring comprehensive, life-long management [9].
