ABSTRACT

Background. The principal cause of iron overload in patients with haematological malignancies is recurrent red cell transfusions for anaemia. The serum ferritin level reflects the iron burden in the body, in the absence of inflammation or liver disease. In Malaysia, data are lacking on the association between pre-transplant serum ferritin levels and outcome after allogeneic haemopoietic stem cell transplant. Methods. We did a cross-sectional study using retrospective data of 106 post-allogeneic haemopoietic stem cell transplant patients (HLA-matched sibling) with haematological malignancies at Hospital Ampang to determine the relationship between pre-transplant serum ferritin levels and post-transplant outcome, post-transplant complications and survival time. Patients were divided into two groups according to the iron status: serum ferritin level >1000 μg/L (iron overload) and <1000 μg/L. Results. The median age for patients was 30.5 (18–58) years. The median pre-transplantation serum ferritin level and the prevalence of pre-transplantation iron overload were 2423 (408.2–7664) μg/L and 87.5%, respectively. No significant association was found between iron status and demographic factors, type of haematological malignancy and post-transplant complications. Although insignificant, patients with iron overload had a shorter survival time (36 months) compared to those with no iron overload (40 months). There was also no significant association between the iron status and post-transplant outcome. Significant post-transplant complications associated with post-transplant outcome were the need for total parenteral nutrition (TPN) (p=0.014) and chronic graft-versus-host disease (GVHD) (p=0.008). Similarly, significant associations were found between age group (p=0.003), TPN (p=0.035) and chronic GVHD ———————————————————————————————

ABSTRACT

The haemoglobinopathies and thalassemias represent the most common inherited monogenic disorders in the world. Beta-thalassaemia major is an ongoing public health problem in Malaysia. Prior to 2004, the country had no national policy for screening and registry for thalassemia. In the absence of a national audit, the true figure of the extent of thalassemia in the Malaysian population was largely presumptive from micro-mapping studies from various research workers in the country. The estimated carrier rate for beta-thalassemia in Malaysia is 3.5-4%. There were 4768 transfusion dependent thalassemia major patients as of May 2010 (Data from National Thalassemia Registry).
