Background Regular blood transfusions and chelation are the mainstay of treatment in TDT patients. This has improved the survival and prognosis of the patients. Cardiac complications still remain to be the main cause of mortality. Cardiac iron toxicity is the main cause of complications leading to cardiac failure. MRI T2 is the gold standard for diagnosing cardiac iron toxicity, however this facility is limited in Indonesia.Objective.This study aimed to get a profile of the cardiac iron toxicity in adult TDT beta major patients to obtain a correlation of cardiac iron toxicity with cardiac function and NTproBNP levels and to evaluate if there is any correlation between iron overload with cardiac iron toxicity, cardiac function and NTproBNP levels.Methods Cross sectional study was done which included thalassemia beta major transfusion dependent patients from the adult thalassemia policlinic of RSCM hospital during desember 2017. Data was obtained from the medical records including history, laboratory results and results of MRIT2 and echocardiography. Physical examination was done and blood drawn for NTproBNP estimation. Data was analysed for descriptive data and correlation tests using pearsons or spearman rsquo s test.Results 62 patients were included in the study. Median cardiac T2 was 24.96 ms. 27.4 patients had mild moderate cardiac hemosiderosis and 11.3 had severe cardiac siderosis. There was no correlation between cardiac iron toxicity and ejection fraction, E A ratio and NTproBNP levels. There was a weak correlation between ferritin levels and cardiac toxicity r 0,312, p 0,007 as well as with ejection fraction r 0,281, p 0,013. There was no correlation between ferritin levels and E A or NTproBNP. There was no correlation between transferrin saturation levels with cardiac iron toxicity, ejection fraction, E A ratio as well as NTproBNPConclusion Cardiac iron toxicity was seen in 38,7 of TDT patients in this study. There was no correlation between cardiac toxicity and cardiac functions as well as NTproBNP levels. There was a weak correaltion between ferritin levels with cardiac toxicity and systolic function but no correlation with diastolic function. There was no correlation between transferrin saturation levels with cardiac toxicity, systolic function, diatolic function as well NtproBNP levels."

"Latar Belakang: Thalassemia adalah penyakit herediter, dan anemia berat adalah salah satu fenotip utama pada thalassemia mayor, sehingga transfusi sel darah merah adalah modalitas utama tatalaksana. Transfusi sel darah merah diberikan sebanyak 1-2 kali setiap bulan akan meningkatkan kesintasan, tetapi dapat meningkatkan risiko infeksi dan menyebabkan muatan besi berlebih, terutama pada penderita thalassemia bergantung transfusi/transfusion dependent thalassemia TDT. Infeksi adalah penyebab kematian kedua pada TDT, setelah gagal jantung. Risiko infeksi meningkat pada transfusi berulang, hal ini terjadi karena adanya infeksi akibat transfusi, dan perubahan respon imun. Perubahan respon imun terjadi karena adanya aloimunisasi dan muatan besi berlebih.Perubahan respon imun dalam TDT dapat terjadi baik dalam respon imun inat maupun imun spesifik. Dalam studi sebelumnya terdapat korelasi ferritin serum dengan jumlah CD4, tetapi hal ini belum diteliti di Indonesia.Tujuan: Mendapatkan korelasi antara muatan besi berlebih ferritin serum dan saturasi transferin dengan imuitas selular CD4 pada penderita dewasa thalassemia beta bergantung transfusi.Metode: Penelitian ini adalah studi potong lintang. Pengambilan sampel secara konsekutif pada TDT dewasa. Jumlah subjek adalah 64 orang. Subjek melakukan ronsen toraks dan pemeriksaan laboratorium darah. Pemeriksaan HBsAg, anti HCV, anti HIV diperiksa dengan menggunakan metode Electroimmunoassay ELISA . Serum feritin, dan saturasi transferin diperiksa menggunakan metode Electrocheminulescentimmunoassay ECLIA . Limfosit subset diperiksa menggunakan flowcytometer. Uji korelasi dengan menggunakan korelasi Spearman`s.Hasil: Pada penelitian ini mendapatkan proporsi Hepatitis B sebanyak 4,7 , Hepatitis C positif sebanyak 10,9 , tidak ditemukan anti HIV dan ditemukan 4 dari 41 subjek yang mengalami TB paru. Hasil uji Spearman menunjukkan korelasi negatif lemah dan tidak bermakna antara ferritin serum dengan CD4 p= 0,75, r= -0,04 , dan korelasi positif lemah dan tidak bermakna antara saturasi transferin dengan CD4 p= 0,133, r= 0,19 .Simpulan: Tidak terdapat korelasi yang bermakna antara muatan besi ferritin serum dan saturasi transferin dengan imunitas seluler CD4.

Background Thalassemia is a hereditary disease and severe anemia is main phenotype in major thalassemia, therefore red cell transfusion is main modality in major thalassemia management. Transfusion which are given 1 2 times every month will improve prognosis and survival, but both higher risk infections and iron overload are found in thalassemia, especially in transfusion dependent thalassemia TDT. Infections are second cause of death in adult TDT, after heart failure. Higher risk infections are caused by multiple transfusions, which can cause alter in immune response due to alloimunization, transfusion related infections and iron overload. Iron overload in TDT can altered immune response, both innate immune and specific immune. Some studies showed correlation between ferritin and CD4, but these were not yet studied in IndonesiaObjective. Objectives in this study were to determine correlations between iron overload serum ferritin and transferrin saturation and immune cellular specific CD4 Methods This were cross sectional study. Subjects were examined consecutively with chest x ray and serum blood collections. Total subjects were 64 subjects. HBsAg, anti HCV, anti HIV, were tested using ELISA. Serum Ferritin, and transferin saturation were tested using ECLISA. lymphocyte subsets were analyzed using flowcytometer. Correlations tests used Spearman rsquo s test.Results We found proportion HBsAg 4,9 positive, Anti HCV positive 10,7 , no subjects with positive for anti HIV, and there was 4 41 subjects with lung tuberculosa from chest X ray. There were weak negative correlation and not significant between serum ferritin with CD4 p 0,75, r 0,04 , and weak positive correlation and not significant between transferrin saturation with CD4 p 0,133, r 0,19 .Conclusions There were no correlations between iron overload ferritin and cellular immunity CD4 in adult transfusion dependent thalassemia."

Background: Achieving the target of blood transfusion in transfusion-dependent beta thalassemia patients is influenced by various factors including genotype, hypersplenism, blood compatibility, donor blood adequacy and transfusion interval. The size of the spleen can be one indicator of the success of achieving blood transfusion targets in addition to hemoglobin levels.

Objective: Determine the proportion of patients who achieve the optimal target hemoglobin level pre and post transfusion, determine the factors that are related to achieving pre and post transfusion hemoglobin levels and assess the relationship between achieving pre and post transfusion hemoglobin levels with spleen size in adult beta thalassemia transfusion dependent patients.

Methods: A cohort retrospective study, with total sampling of 200 adult thalassemia transfusion dependent patient at Cipto Mangunkusumo Hospital. Data taken from 110 eligible subject in the form of medical history, physical examination and laboratory.

Result: 200 transfusion-dependent beta thalassemia patients who routinely visit the RSCM thalassemia Kiara polyclinic, followed in cohort from June 2017 to June 2018. 110 study subjects fulfilled the inclusion criteria including 53 (48.2%) major beta thalassemia subjects and transfusion-dependent HbE beta 57 (51.8%). The proportion of subjects who achieved pre-transfusion Hb target levels was 18 (16.4%) and 22 (20.0%) subjects who achieved the post Hb target. A total of 8 (7.3%) subjects achieved pre and post transfusion Hb levels. The donor blood adequacy factor is related to the achievement of pre and post transfusion Hb target levels (p = 0.008), namely subjects who only have a blood demand difference of <30ml/KgBB/year. In 93 research subjects, there was a significant difference between groups who achieved pre and post-transfusion Hb levels with those that were not reached against the delta of spleen size (p <0.001).

Conclusion: Adequacy factor of donors blood is related to achieving target pre and post transfusion hemoglobin levels. The achievement of the target pre and post transfusion hemoglobin levels is related to the size of the spleen."

ABSTRACTBackground Iron overload is a common feature of thalassemia intermedia due to regular blood transfusion and increase gastrointestinal iron absorption. Early detection and adequate iron chelator can significantly decrease related morbidities and mortality due to complication from iron overload. Liver Iron Concentration LIC is the best way to measure body iron stores. MRI T2 as a validated test to identify LIC, is expensive and currently not available in all medical services in Indonesia.Objective To identify liver iron overload and correlation of transferrin saturation, serum ferritin, liver MRI T2 , and LIC with transient liver elastography in adult thalassemia intermedia patient.Methods We conducted a cross sectional study enrolling 45 patients with thalassemia intermedia with blood transfusion and with and without iron chelator therapy. The study was conducted at Cipto Mangunkusumo Hospital from August 2016 through October 2016. We performed measurements of transferrin saturation, serum ferritin level, transient liver elastography and liver MRI T2 . The Pearson and Spearman correlation test were used to evaluate the correlation transient liver elastography with transferrin saturation, serum ferritin, Liver MRI T2 , and LIC.Results As much as 64,4 of study subject are Hb E Thalasemia Intermedia with median IQR age is 33 22 years old. As much as 84,4 of study subject have regular blood transfusion. On the basis of liver MRI T2 , all studi subject suffered from liver iron overload, with 48,9 had severe liver iron overload. The median value of Liver MRI T2 was 1,6 ms. The mean serum ferritin was 2831 1828 ng mL, with median value of transferrin saturation was 66 . The mean of LIC corresponding to Liver MRI T2 and mean liver stiffness measurement was 15,36 7,37 mg Fe gr dry weight and 7,7 3,8 Kpa respectively. Liver Stiffness correlated with serum ferritin r 0,651 p 0,000 , Liver MRI T2 r 0,357 p 0,016 , and LIC r 0,433 p 0,003 . No correlation was found between liver elastography and transferrin saturation r 0,204 p 0,178 .Conclusions Serum ferritin, Liver MRI T2 , and LIC correlated with liver elastography. No correlation was found between transferin saturation and liver elastography. "
