Management and treatment Treatment is supportive and involves hematological monitoring, the surveillance of iron levels, lifetime pyridoxine supplementation in those who respond and folic acid supplementation. [orpha.net]

Treatment The underlying cause determines the course of treatment. Hereditary sideroblastic anemia usually responds to several weeks of treatment with high doses of pyridoxine. [doctor-clinic.org]

Molecular analysis of these cases will contribute not only to the development of effective treatment, but also to the understanding of mitochondrial iron metabolism. [ncbi.nlm.nih.gov]

A normal karyotype carries the most favorable prognosis. Monosomy 7 or deletions of the long arms of chromosome 7 are associated with a worse prognosis. “What if” scenarios. [psychiatryadvisor.com]

Prognosis Prognosis is variable but for patients with pyridoxine-responsive anemia whose iron stores are kept low, normal life expectancy should be achievable The documents contained in this web site are presented for information purposes only. [orpha.net]

Few patients are eligible for transplant. [ 1 ] Prognosis [ 9 ] The prognosis is very variable. Reversible causes (eg, alcohol or drugs) appear to have no long-term effects if the underlying cause is successfully treated or removed. [patient.info]
