Background:Hepcidin is a key regulator of iron absorption in humans. It is mainly affected by hypoxia and iron stores.Objectives:The current study aimed to determine the correlation between serum hepcidin and ferritin levels in patients with Thalassemia Major (TM) and Thalassemia Intermedia (TI).Patients and Methods:The current cross-sectional study investigated 88 randomly selected patients with Thalassemia, 48 TM and 40 TI, registered at the Thalassemia Clinic of Shiraz University of Medical Sciences, a referral center for Thalassemia in Southern Iran in 2013. All patients with TI were receiving Hydroxyurea (HU) 10 - 15 mg/kg/day for at least 10 years. The serum hepcidin, ferritin levels, hemoglobin (Hb) and nucleated Red Blood Cell (RBC) of the two groups were measured.Results:No statistically significant correlation was observed between serum hepcidin and ferritin levels in any of the two groups of patients with TM (rs = 0.02, P = 0.892) or TI (rs = 0.055, P = 0.734). The median Interquartile Range (IQR) for serum hepcidin and ferritin levels were significantly higher in TM compared to TI group, (hepcidin: 87.6 (43.9) vs. 51.8 (23.4), P < 0.001; ferritin: 2208 (3761) vs. 465 (632), P < 0.001).Conclusions:There was insignificant correlation between serum hepcidin and ferritin levels in the two groups of patients with TM and TI. It seems that regulation of hepcidin in patients with Thalassemia is more affected by erythropoeitic activity than iron stores. Also, hepcidin levels were significantly higher in patients with TM than TI, possibly due to higher erythropoeitic activity in TI. In TI, it seems that low dose HU increases Hb levels and leads to transfusion-independence, but it is not high enough to suppress bone marrow activity and ineffective erythropoiesis. Consequently, serum hepcidin level decreases.
The study suggests that combination chelating therapy with deferasirox and deferoxamine can effectively reduce iron burden in β-thalassemia major patients with heavy iron overload without any significant complications.
OBJECTIVES:The survival rate of thalassemia patients has not been conclusively established, and the factors associated with survival remain unclear. This study aimed to determine the survival rate of thalassemia among patients in southern Iran and to identify the factors associated with mortality from thalassemia.METHODS:This retrospective cohort study was conducted based on a retrospective review of the medical records of 911 beta-thalassemia patients in 2014. Data analysis was conducted using the Kaplan-Meier method and Cox regression analysis.RESULTS:Overall, 212 patients (23.3%) died, and 26.8% had thalassemia intermedia. The 20-year, 40-year, and 60-year survival rates were 85%, 63%, and 54%, respectively. Both crude and adjusted analyses found that education, marital status, ferritin levels, and comorbidities were related to mortality.CONCLUSIONS:Sociodemographic and hematological factors were found to be significantly associated with the survival rate of thalassemia. Addressing these factors may help healthcare providers and physicians to provide the best possible care and to improve the survival rate.
This study aimed to determine the frequency and pattern of complementary and alternative medicine (CAM) use in thalassemia patients in south of Iran. The survey was done using a validated questionnaire which was distributed among 122 thalassemia patients. Only 108 questionnaires were completed and turned back (response rate 88.5%). Patients referred to an outpatient thalassemia clinic in Shiraz, southern Iran for blood transfusion. The mean age of the patients was 22.9 ± 7.9 years (range 4–45 years) with female/male ratio 1.84. Seventy four (68.5%) of the responders used CAM at least once during their life, and about half of them used it concurrently with their conventional treatments. The most reported CAM product was mint juice (50%). The most common reason of CAM use was increased general health. The most common information source about CAM was physicians who were the most trusted source as well. CAM is frequently being used in thalassemia patients to ensure their sense of well-being and help them overcome the complications of their illnesses.
Because of insufficient erythropoiesis, peripheral hemolysis and increased gastrointestinal iron absorption, iron overload is still a matter of debate in β-thalassemia intermedia (β-TI) patients, which can be overcome using iron chelators. However, data on use of iron chelators in β-TI patients is highly restricted. The aim of this study was to evaluate the efficacy of oral administration of deferasirox (Exjade(®) or DFX) by assessment of serum ferritin levels in β-TI patients. In this quasi-experimental study, 50 β-TI patients with serum ferritin levels >1000 ng/mL were selected and received oral DFX for 12 consecutive months. Iron overload was measured by checking serum ferritin levels every 2 months and the results were compared with the baseline level. The mean serum ferritin was decreased during 1 year of chelation therapy without any toxic effect. Although the difference between baseline ferritin and ferritin levels at the end of second month was not remarkable (p = 0.88), a significant reduction in serum ferritin was observed after 4 (p = 0.01), 6 (p = 0.001), 8 (p < 0.001), 10 (p < 0.001) and 12 months (p < 0.001) of chelation therapy compared to its baseline levels. There was no correlation between baseline ferritin levels and age (p = 0.574). In addition, no statistically significant difference was observed about change in serum ferritin levels after 6 and also 12 months of therapy between patients who had undergone splenectomy and those who did not (p = 0.796 and 0.859, respectively). Iron chelation therapy with DFX is safe and effective in reducing serum ferritin levels in β-TI patients who suffer from side effects of iron overload.
