RESUMO

Background: Splenectomy has been performed for various indications from haematological diseases to benign cysts and tumours, and for splenic traumatic injuries. However, there has been a steady decline in splenectomies in the last 20 years. The aim of this study is to establish the reasons behind this decline in splenectomy and to analyse them based on indication, type of splenectomy, and manner of approach (open, laparoscopic or robotic). Material and Methods: This is a retrospective study of a single centre experience of all the splenectomies, both total and partial, performed in the Department of General Surgery of Fundeni Clinical Institute (Bucharest) between 2002 and 2023. Only surgeries for primary splenic diseases were selected, splenic resections as part of other major operations were not included. Results: Between 2002 and 2023, 876 splenectomies were performed in the Department of General Surgery of Fundeni Clinical Institute (Bucharest). Most splenectomies (n=245) were performed for immune thrombocytopenic purpura (ITP), followed by benign tumours and cysts (n=136), lymphoma (n=119), hypersplenism due to cirrhosis (n=107) and microspherocytosis (n=95). Other indications included myelodysplastic syndrome (n=39), trauma (n=35), thalassemia (n=22), leukaemia (n=18) and also there were 60 splenectomies that were performed for hypersplenism of unknown cause. There were 795 total splenectomies (TS) and 81 partial splenectomies (PS). There was a decline in the number of splenectomies both TS and PS for all these indications, most notably in the case of ITP, microspherocytosis and hypersplenism due to cirrhosis with no splenectomies performed for these indications since 2020. Conclusion: With the development of new lines of treatment, advances in interventional radiology and in surgery with the spleen parenchyma sparing options, the need for total splenectomy has been greatly reduced which is reflected in the decline in the number of splenectomies performed in the last 20 years in our clinic.

RESUMO

To explore a noninvasive method for diagnosis of SEA-thalassemia and to investigate whether the regional factors affect the accuracy of this method. The method involved using a public database and bioinformatics software to construct parental haplotypes for proband and predicting fetal genotypes using relative haplotype dosage. We screened and downloaded sequencing data of couples who were both SEA-thalassemia carriers from the China National Genebank public data platform, and matched the sequencing data format with that of the reference panel using Ubuntu system tools. We then used Beagle software to construct parental haplotypes, predicted fetal haplotypes by relative haplotype dosage. Finally, we used Hidden Markov Model and Viterbi algorithm to determine fetal pathogenic haplotypes. All noninvasive fetal genotype diagnosis results were compared with gold standard gap-PCR electrophoresis results. Our method was successful in diagnosing 13 families with SEA-thalassemia carriers. The best diagnostic results were obtained when Southern Chinese Han was used as the reference panel, and 10 families showed full agreement between our noninvasive diagnostic results and the gap-PCR electrophoresis results. The accuracy of our method was higher when using a Chinese Han as the reference panel for haplotype construction in the Southern Chinese Han region as opposed to Beijing Chinese region. The combined use of public databases and relative haplotype dosage for diagnosing SEA-thalassemia is a feasible approach. Our method produces the best noninvasive diagnostic results when the test samples and population reference panel are closely matched in both ethnicity and geography. When constructing parental haplotypes with our method, it is important to consider the effect of region in addition to population background alone.

RESUMO

OBJECTIVE: To explore the plasma metabolomic characteristics of children with transfusion-dependent thalassemia (TDT), and reveal the changes of metabolic pattern in children with TDT. METHODS: 23 children with TDT who received regular blood transfusion in Ganzhou Women and Children's Health Care Hospital in 2021 were selected, and 11 healthy children who underwent physical examination during the same period were selected as the control group. The routine indexes between children with TDT and the control group were compared, and then the metabolic composition of plasma samples from children with TDT and the control group was detected by liquid chromatography-mass spectrometry. An OPLS-DA model was established to perform differential analysis on the detected metabolites, and the differential metabolic pathways between the two groups were analyzed based on the differential metabolites. RESULTS: The results of routine testing showed that the indexes of ferritin, bilirubin, total bile acid, glucose and triglycerides in children with TDT were significantly higher than those in healthy controls, while hemoglobin and total cholesterol were significantly lower (all P <0.05). However there was no significant difference in lactate dehydrogenase between the two groups (P >0.05). Compared with the control group, 190 differential metabolites (VIP>1) were identified in TDT children. Among them, 168 compounds such as arginine, proline and glycocholic acid were significantly increased, while the other 22 compounds such as myristic acid, eleostearic acid, palmitic acid and linoleic acid were significantly decreased. The metabolic pathway analysis showed that the metabolic impact of TDT on children mainly focused on the upregulation of amino acid metabolism and downregulation of lipid metabolism. CONCLUSION: The amino acid and lipid metabolism in children with TDT were significantly changed compared with the healthy control group. This finding is helpful to optimize the treatment choice for children with TDT, and provides a new idea for clinical treatment.

RESUMO

BACKGROUND: Thalassemia is the most prevalent hereditary anaemia worldwide. Severe forms of thalassemia can lead to reduced life expectancy due to disease-related complications. OBJECTIVES: To investigate the survival of thalassemia patients across varying disease severity, causes of death and related clinical factors. PATIENTS AND METHODS: We conducted a retrospective review of thalassemia patients who received medical care at Chiang Mai University Hospital. The analysis focused on survival outcomes, and potential associations between clinical factors and patient survival. RESULTS: A total of 789 patients were included in our study cohort. Among them, 38.1% had Hb H disease, 35.4% had Hb E/beta-thalassemia and 26.5% had beta-thalassemia major. Half of the patients (50.1%) required regular transfusions. Sixty-five patients (8.2%) had deceased. The predominant causes of mortality were infection-related (36.9%) and cardiac complications (27.7%). Transfusion-dependent thalassemia (TDT) (adjusted HR 3.68, 95% CI 1.39-9.72, p = 0.008) and a mean serum ferritin level ≥3000 ng/mL (adjusted HR 4.18, 95% CI 2.20-7.92, p < 0.001) were independently associated with poorer survival. CONCLUSIONS: Our study highlights the primary contributors to mortality in patients with thalassemia as infection-related issues and cardiac complications. It also underscores the significant impact of TDT and elevated serum ferritin levels on the survival of thalassemia patients.

RESUMO

BACKGROUND: Beta thalassemia is a lifelong disease involving malformed red blood cells (RBC). One of the disease's complications is hypogonadism, in which adults tend to exhibit regression in sexual characteristics, experience sexual dysfunction, and therefore have a lower quality of life. Around 3-10% of the Indonesian population carries the beta-thalassemia gene. This study aimed to see the proportions of hypogonadism in transfusion-dependent thalassemia patients and its contributing factors. METHODS: This is a cross-sectional study involving 60 male patients admitted to three Indonesian general hospitals from July 2022 to July 2023. All patients were diagnosed with beta-thalassemia via chromatography hemoglobin analysis. We performed a single-time physical examination and laboratory examinations to determine FSH, LH, and free testosterone levels. The correlation between Hb and sexual hormone levels was analyzed using Spearman's rank correlation coefficient. ROC curve analysis was conducted afterward. All statistical analysis was done in SPSS version 29. RESULTS: 31 out of 60 thalassemia patients had hypogonadism. Pre-transfusion Hb count was found to be linearly correlated with FSH (r = 0.388, p = 0.049), LH (r = 0.338, p = 0.008), and free testosterone (r = 0.255, p = 0.049). ROC analysis indicated that pre-transfusion Hb was viable as a predictor for hypogonadism (AUC = 0.655, 65.5% sensitivity, 67.7% specificity). CONCLUSION: We confirmed the role of pre-transfusion Hb count as a potential predictor for hypogonadism due to the tissue hypoxia mechanism and transfusion-related iron overload in TDT patients. Decreased Hb is linearly correlated with FSH, LH, and testosterone levels. Decreased Hb also downregulates these factors.

RESUMO

BACKGROUND: Osteoporosis is a major problem in transfusion-dependent thalassemia patients (TDT) patients. Osteoprotegerin (OPG) is one of several bone markers that are closely associated with osteoporosis in TDT patients. OPG is a glycoprotein that functions as a feedback receptor for the Receptor Activator of Nuclear Factor kappa B Ligand (RANKL), which is an alpha tumor necrosis factor receptor. One of the causes of decreased bone mass density is iron toxicity, which can be identified by showing elevated transferrin saturation. Bone mass dual X-ray absorptiometry (DEXA) is a gold standard for the diagnosis of osteoporosis, these procedures are not commonly available in Indonesia. This study was conducted to analyze the correlation between serum levels of OPG and transferrin saturation in TDT patients. METHODS: A correlational study with a cross-sectional approach analyzed data from TDT patients at Hemato-Oncology Medic Outpatient Clinic, Hasan Sadikin General Hospital, Bandung, Indonesia. Primary data were obtained through blood sampling and anthropometry measurement while secondary data were obtained from the patient's medical records. OPG and transferrin saturation levels were assessed using the ELISA method. Research data were analyzed using the rank Spearman correlation test. RESULTS: Data were collected from 51 research subjects (30 women dan 21 men). The median OPG level was 380 (170-1230) pg/mL and the median transferrin saturation level was 89.4 (66.7 - 96.2)%. Analysis of correlation showed a significant correlation between and transferrin saturation level with a coefficient value of r -0.539 and p-value <0.001. CONCLUSION: There was a significant inverse correlation between OPG with transferrin saturation in TDT patients.

RESUMO

Background and Objectives: The effective management of chronic diseases, particularly hereditary and rare diseases and thalassaemia, is an important indicator of the quality of healthcare systems. We aimed to assess healthcare services in different countries for thalassaemia patients by using publicly available health indicators and by surveying thalassaemia patients and their caregivers. Materials and Methods: We reviewed official worldwide databases from the WHO, World Bank, and scientific resources, and we used a structured patient-tailored self-completed questionnaire to survey thalassaemia patients and their caregivers in 2023. Results: A total of 2082 participants were surveyed (mean age, 27 years; males, 42%). About 1 in 4 respondents did not complete high-school education, while 24% had a bachelor's degree. About a third of respondents were married and were in either full- or part-time employment. The vast majority (~80%) had initiated transfusion therapy between 1 and 4 years of age. Only 42% reported no delays in receiving blood transfusion, while 47% reported occasional delays and 8% serious delays. About half of patients reported being very satisfied (11%) or satisfied (38%) with the quality of services provided, while 1 in 3 patients reported being unsatisfied or very unsatisfied, and that their access to treatment was difficult or very difficult due to traveling expenses and the high cost of treatment. Conclusions: Important improvements in the care of thalassaemia patients have been documented during the past few decades. Nevertheless, additional focus is required through national healthcare systems to effectively address the many unmet needs revealed by our recent survey, as well as to achieve satisfactory patient outcomes.

RESUMO

Thalassemia is most widely distributed single gene autosome recessive genetic disease in the world, whose clinical manifestation was changed from asymptomatic anemia to severe anemia requiring continous blood transfusion to maintain life, thus resulting in a serious economic burden to society and families. Therefore, it is necessary to carry out the corresponding prentatal screening and diagnosis. Most of the conventional detection methods can only detect the common thalassemia genotype, it can easy to cause misdiagnosis or missed diagnosis for those rate genetic variantions. The third-generation sequecing (TGS) has been applied to the detection of thalassemia genes, which is more accurate, reliable and superior to the converntional detection methods. This article reviews the latest research progress of the TGS technology in genetic testing of thalassemia.

RESUMO

Objective: Increased survival rate of patients with Transfusion-dependent Thalassemia (TDT) should be in line with their good quality of life (QoL). The study aimed to analyze the relationship between sociodemographic factors and clinical characteristics with the QoL of children with TDT. Methods: A cross-sectional study was conducted at Hasan Sadikin General Hospital from December 2022 to February 2023. A total of 158 eligible subjects aged 5-18 years with TDT were included in the analysis. QoL assessment was performed using child self-report and parent-proxy report questionnaires, along with physical examination findings. Bivariate and multivariate analyses were conducted to analyze the data. Results: A total of 158 subjects who met the research criteria were included in the analysis. Of 58.9% of children with TDT had a low adherence rate to iron chelating therapy (ICT). School function had the lowest score in QoL based on child-self report and parent proxy. Gender (p<0,05) and adherence to ICT (p<0,05) were significantly associated with lower quality of life. Conclusion: Female and adherence to ICT were predictors of children with TDT's QoL.

RESUMO

Hemoglobinopathies are monogenic disorders affecting hemoglobin synthesis. Thalassemia and sickle cell disease (SCD) are considered the two major hemoglobinopathies. Thalassemia is a genetic disorder and one of the major hemoglobinopathies determined by an impairment of globin chain production, which causes an alteration of erythropoiesis, an improvement in hemolysis, and an alteration of iron homoeostasis. In SCD, the mutations are on the ß-globin chain of hemoglobin which results in a substitution of glutamic acid by valine with consequent formation of Hemoglobin S (HbS). Several factors are involved in bone metabolism alteration in patients with hemoglobinopathies, among them hormonal deficiency, bone marrow hyperplasia, iron overload, inflammation, and increased bone turnover. Bone metabolism is the result of balance maintenance between bone deposition and bone resorption, by osteoblasts (OBs) and osteoclasts (OCs). An impairment of this balance is responsible for the onset of bone diseases, such as osteoporosis (OP). Therefore, here we will discuss the alteration of bone metabolism in patients with hemoglobinopathies and the possible therapeutic strategies to contain and/or counteract bone health impairment in these patients, taking into consideration not only the pharmacological treatments already used in the clinical armamentarium, but also the new possible therapeutic strategies.

RESUMO

Hematopoietic stem cell (HSC) gene therapy has shown potential as a therapeutic approach for thalassemia in recent years. However, a comparison of the varying gene therapy methods of HSC gene therapy in thalassemia has never been reviewed. This study aims to evaluate the utilization of HSC gene therapy approaches in animal models of thalassemia. A systematic review was conducted in five databases: PubMed, EBSCOHost, Science Direct, SCOPUS, and Proquest using a combination of the terms hematopoietic stem cell or hematopoietic stem cell or HSC, thalassemia, genetic therapy or gene therapy and animal model. Only journals published in English between 2008 and 2023 were included. This literature included six studies analyzing the use of HSC gene therapy in thalassemic mice models. The three outcomes being assessed in this review were globin levels, hematological parameters, and red blood cell (RBC) phenotypes. Gene therapy approaches for thalassemia using HSC showed significant improvement in ß-globin levels and RBC phenotypes. Phenotypic improvements were also observed. These outcomes indicate good efficacy in gene therapy for thalassemia in mice models. Furthermore, more studies assessing the efficacy of HSC gene therapy in the human model should be done in future studies.

RESUMO

BACKGROUND: In pediatric transfusion-dependent thalassemia (TDT) patients, we evaluated the prevalence, pattern, and clinical associations of pancreatic siderosis and the changes in pancreatic iron levels and their association with baseline and changes in total body iron balance. PROCEDURE: We considered 86 pediatric TDT patients consecutively enrolled in the Extension-Myocardial Iron Overload in Thalassemia Network. Iron overload (IO) was quantified by R2* magnetic resonance imaging (MRI). RESULTS: Sixty-three (73%) patients had pancreatic IO (R2* > 38 Hz). Global pancreas R2* values were significantly correlated with mean serum ferritin levels, MRI liver iron concentration (LIC) values, and global heart R2* values. Global pancreas R2* values were significantly higher in patients with altered versus normal glucose metabolism. Thirty-one patients also performed the follow-up MRI at 18 ± 3 months. Higher pancreatic R2* values were detected at the follow-up, but the difference versus the baseline MRI was not significant. The 20% of patients with baseline pancreatic IO showed no pancreatic IO at the follow-up. The 46% of patients without baseline pancreatic IO developed pancreatic siderosis. The changes in global pancreas R2* between the two MRIs were not correlated with baseline serum ferritin levels, baseline, final, and changes in MRI LIC values, or baseline pancreatic iron levels. CONCLUSIONS: In children with TDT, pancreatic siderosis is a frequent finding associated with hepatic siderosis and represents a risk factor for myocardial siderosis and alterations of glucose metabolism. Iron removal from the pancreas is exceptionally challenging and independent from hepatic iron status.

RESUMO

The study aimed to determine efficacy and safety of generic deferasirox monotherapy. Deferasirox was administered in transfusion-induced iron overloaded thalassemia. Efficacy was defined as responders and nonresponders by ≤ 15 reduced serum ferritin from baseline. Adverse events were also monitored. Fifty-two patients with mainly Hb E/ß-thalassemia at the mean (SD) age of 8.7 (4.1) years, were enrolled. The mean (SD) daily transfusion iron load was 0.47 (0.1) mg/kg and maximum daily deferasirox was 35.0 (6.2) mg/kg. Altogether, 52, 40 and 18 patients completed the first, second and third years of study, respectively. The median baseline serum ferritin 2,383 ng/mL decreased to 1,478, 1,038 and 1,268 ng/mL at the end of first, second and third years, respectively, with overall response rate at 73.1% (38/52). Patients with baseline serum ferritin >2,500 ng/mL showed a change in serum ferritin higher than those ≤2,500 ng/mL starting from the 9th month of chelation. Adverse events were found in 5 of 52 patients (9.6%) including transaminitis (n = 2), one each of proteinuria, rash and proximal tubular dysfunction which resolved after transient stopping or decreasing the chelation dose. Generic deferasirox was effective and safe among pediatric patients with transfusion-induced iron overloaded thalassemia.

RESUMO

OBJECTIVES: Graft-versus-host disease (GvHD) is one of the leading causes of morbidity and mortality in patients undergoing allogeneic HSCT, and effective prevention of GvHD is critical for the success of the HSCT procedure. Calcineurin inhibitors (CNI) have been used for decades as the backbone of GvHD prophylaxis. In this study, the efficacy and safety of Cyclosporine A (CsA) and tacrolimus (TCR) were compared in pediatric HSCT for thalassemia. MATERIALS AND METHODS: This is a retrospective analysis of 129 pediatric patients who underwent HSCT with the diagnosis of thalassemia at Medicalpark Göztepe and Antalya Hospitals between January 2017 and December 2020. RESULTS: Despite the GvHD prophylaxis, grade II-IV acute GvHD developed in 29 patients. Of these patients, 12 had only gut, 10 had only skin, 6 had combined gut and skin, and one had only liver GvHD. Fifteen of these 29 patients were in the CsA group, and 14 of them were in the TCR group. There was no significant difference between the groups in terms of acute GvHD occurrence, GvHD stage, or involvement sites. In terms of CNI-related toxicity, neurotoxicity in 15 (CsA n = 9, TCR n = 6) and nephrotoxicity in 18 (CsA n = 4, TCR n = 14) patients were observed. While there was no difference between the two groups in terms of neurotoxicity, more nephrotoxicity developed in patients using TCR (p = .013). There was no significant difference between the groups in terms of engraftment syndrome, veno-occlusive disease, CMV reactivation, PRES, or graft rejection. CONCLUSION: Regarding GvHD, there was no difference in efficacy between TCR and CsA usage. Patients taking TCR experienced noticeably higher nephrotoxicity in terms of adverse effects. This difference should be considered according to the patient's clinical situation while choosing a CNI.

RESUMO

BACKGROUND: Congenital diseases are still an important medical, social, and economic problem all over the world. In North Cyprus, in addition to other reasons, early prenatal diagnostic measures are undertaken to prevent births with thalassemia major, a locally widespread genetic disease. AIM: This study aims to evaluate the results of prenatal invasive diagnostic tests performed in a private obstetrics clinic in Northern Cyprus and show the diagnosis process of thalassemia and chromosomal anomalies. MATERIALS AND METHODS: This study is a retrospective, descriptive study. Chorionic villus sampling (CVS) results and the amniocentesis tests performed between 1990 and 2022 are evaluated. Thalassemia and chromosome analysis of samples obtained by CVS and amniocentesis tests were performed. To diagnose alpha or beta thalassemia and sickle cell, 239 CVS was performed. And to diagnose chromosomal anomalies, 396 CVS and amniocentesis were performed. RESULTS: The mean age of the 480 pregnant women included in the study was 31.12 years (18-46) and 30% of them were older than 34 years. The most common indications for invasive prenatal diagnostic test (IPDT) were; mother/father thalassemia minor/major, advanced maternal age, high risk of ultrasonography erase findings, and the noninvasive screening test. The result of IPDT detected 7.3% chromosomal anomaly and 69.5% thalassemia and sickle cell anemia. Of the 239 CVS performed to diagnose alpha or beta thalasemia and sickle cell, 23.4% beta major, 42.3% beta minor, and 2.1% alpha minor were diagnosed. Of the 396 CVS and amniocentesis performed to diagnose chromosomal anormalies; 2.8% of Down syndrome and 4.54% of other chromosomal anomalies were diagnosed. CONCLUSION: IPDT is important in correctly diagnosing fetal anomalies at the prenatal stage to help families decide at the right time.

RESUMO

PURPOSE: To establish the population pharmacokinetics (PPK) model of cyclosporine A(CsA) in pediatric patients with thalassemia undergoing allogeneic hematopoietic stem cell transplantation (HSCT), aiming at providing a reference for clinical dose individualization of CsA. METHODS: Children with thalassemia who underwent allogeneic HSCT were enrolled retrospectively. The PPK structural model and the random variable model of CsA were established on NONMEN. And goodness of fit plots (GOFs), visual predictive check (VPC), and bootstrap and normalized prediction distribution errors (NPDE) were used to evaluate the final model. RESULTS: A one-compartment model with first-order absorption was employed to fit the base model. A total of 74 pediatric patients and 600 observations of whole blood concentration were included. The final model included weight (WT) in clearance (CL), alongside post-operative day (POD), fluconazole (FLUC), voriconazole (VORI), posaconazole (POSA), and red blood cell count (RBC) significantly. All the model evaluations were passed. CONCLUSION: In the PPK model based on the pediatric cohort on CsA with thalassemia undergoing allogeneic HSCT, WT, POD, FLUC, VORI, POSA, and RBC were found to be the significant factors influencing CL of CsA. The reliability and robustness of the final model were excellent. It is expected that the PPK model can assist in individualizing dosing strategy clinically.

RESUMO

Understanding consequences of poor chelation compliance is crucial given the enormous burden of post-transfusional iron overload complications. We systematically reviewed iron-chelation therapy (ICT) compliance, and the relationship between compliance with health outcome and health-related quality of life (HRQoL) in thalassaemia patients. Several reviewers performed systematic search strategy of literature through PubMed, Scopus, and EBSCOhost. The preferred reporting items of systematic reviews and meta-analyses (PRISMA) guidelines were followed. Of 4917 studies, 20 publications were included. The ICT compliance rate ranges from 20.93 to 75.3%. It also varied per agent, ranging from 48.84 to 85.1% for desferioxamine, 87.2-92.2% for deferiprone and 90-100% for deferasirox. Majority of studies (N = 10/11, 90.91%) demonstrated significantly negative correlation between compliance and serum ferritin, while numerous studies revealed poor ICT compliance linked with increased risk of liver disease (N = 4/7, 57.14%) and cardiac disease (N = 6/8, 75%), endocrinologic morbidity (N = 4/5, 90%), and lower HRQoL (N = 4/6, 66.67%). Inadequate compliance to ICT therapy is common. Higher compliance is correlated with lower serum ferritin, lower risk of complications, and higher HRQoL. These findings should be interpreted with caution given the few numbers of evidence.

RESUMO

PURPOSE: Children living with thalassemia experience psychological challenges, but despite significant psychosocial burdens, caregivers' psychological wellbeing and quality of life remain understudied, particularly in lower-and-middle-income countries. DESIGN AND METHOD: The current study evaluated these relationships in 100 male and female Pakistani caregivers (23-45 years; 61% female) using Ryff's Psychological Well-Being Scale and the Singapore Caregiver Quality of Life Scale. Caregivers completed questionnaires during regularly scheduled clinic visits for their child. RESULTS: We found that Pakistani caregivers in our sample generally had significantly lower (30-40 points) quality of life than a referent sample of caregivers of older adults (ps < 0.001). Self-acceptance and personal growth were consistently significant predictors across quality of life domains. Further, significant interactions were observed. Female caregivers with less self-acceptance had worse mental health and wellbeing and impact on daily life (p < .05). Male caregivers with less personal growth had worse physical health wellbeing (p < .05). CONCLUSIONS: Our results demonstrate the importance of considering how distinct aspects of psychological wellbeing, rather than just the overall score, relate to the specific quality of life domains among male and female caregivers. PRACTICE IMPLICATIONS: Pediatric nurses are at the frontline of service delivery for children and are in a prime position to observe caregivers who could be at high risk for psychological challenges. Given our findings, future clinical interventions should prioritize support services promoting personal growth and self-acceptance for Pakistani caregivers of children living with thalassemia.
