Iron burden and endocrine complications in transfusion-dependent thalassemia patients In Sarawak, Malaysia: a retrospective study.
Introduction: Thalassaemia is one of the major health problems in Malaysia. With safe blood transfusion regime, the lifespan of patients with transfusion-dependent thalassaemia (TDT) has improved but at the cost of a higher risk of developing endocrine disorders. It is crucial for us to monitor the iron overload to prevent end organ damage. This study aims to evaluate the iron burden and prevalence of endocrinopathies in patients with TDT in Sarawak.
Materials and methods: This retrospective cohort study was conducted between January 2020 to June 2020 in six government hospitals in Sarawak. A total of 89 patients with TDT, aged 10 years and above, were recruited.
Results: Out of the 89 patients, there were 54 males (60.7%) and 35 females (39.3%) with a median age of 21 years (range 10.0-65.0). Sixty-seven (75.3%) patients had betathalassaemia major and 15 (16.9%) patients had haemoglobin E beta-thalassaemia (HbE beta-thalassaemia), remaining seven patients had other genotypes. Thirty-one (34.8%) patients had mean serum ferritin 2500ng/ml and above, and 44 (66.6%) had liver iron concentration (LIC) ≥7mg/g. The prevalence of endocrine disorders in our cohort was 69.7%. The most common endocrinopathies were short stature (n=46, 51.7%), followed by hypogonadism (n=24, 26.9%), delayed puberty (n=23, 25.8%), hypothyroidism (n=10, 11.2%), diabetes mellitus (n=9, 10.1%), impaired glucose tolerance (n=6, 6.7%) and hypoparathyroidism (n=3, 3.3%). Endocrinopathies were significantly associated with age (p=0.01), age at initiating regular blood transfusion (p<0.01) and duration of regular blood transfusion (p<0.01).
Conclusion: Our data shows that the development of endocrinopathies in TDT can be time dependent. Early detection of endocrine-related complications and prompt treatment with iron chelation therapy are important to improve morbidity and mortality. A multidisciplinary approach with good patient-doctor collaboration is the key to improving patient care in our settings.
期刊介绍：
Published since 1890 this journal originated as the Journal of the Straits Medical Association. With the formation of the Malaysian Medical Association (MMA), the Journal became the official organ, supervised by an editorial board. Some of the early Hon. Editors were Mr. H.M. McGladdery (1960 - 1964), Dr. A.A. Sandosham (1965 - 1977), Prof. Paul C.Y. Chen (1977 - 1987). It is a scientific journal, published quarterly and can be found in medical libraries in many parts of the world. The Journal also enjoys the status of being listed in the Index Medicus, the internationally accepted reference index of medical journals. The editorial columns often reflect the Association''s views and attitudes towards medical problems in the country. The MJM aims to be a peer reviewed scientific journal of the highest quality. We want to ensure that whatever data is published is true and any opinion expressed important to medical science. We believe being Malaysian is our unique niche; our priority will be for scientific knowledge about diseases found in Malaysia and for the practice of medicine in Malaysia. The MJM will archive knowledge about the changing pattern of human diseases and our endeavours to overcome them. It will also document how medicine develops as a profession in the nation. We will communicate and co-operate with other scientific journals in Malaysia. We seek articles that are of educational value to doctors. We will consider all unsolicited articles submitted to the journal and will commission distinguished Malaysians to write relevant review articles. We want to help doctors make better decisions and be good at judging the value of scientific data. We want to help doctors write better, to be articulate and precise.
