Abstract
Thalassemia is the most common autosomal genetic disorder in humans. The pathogenesis of thalassemia is principally due to the deletion or mutation of globin genes that then leads to disorders in globin-chain synthesis, and its predominant clinical manifestations include chronic forms of hemolytic anemia. However, research on the epigenetics and underlying pathogenesis of thalassemia is in its nascency and not yet been systematically realized. In this study, we compared the results of RNA-seq and the whole-genome bisulfite sequencing (WGBS) on 22 peripheral blood samples from 14 thalassemic patients and eight healthy individuals revealed a genome-wide methylation landscape of differentially methylated regions (DMRs). And functional-enrichment analysis revealed the enriched biological pathways with respect to the differentially expressed genes (DEGs) and differentially methylated genes (DMGs) to include hematopoietic lineage, glucose metabolism, and ribosome. To further analyze the interaction between the transcriptome and methylome, we implemented a comprehensive analysis of overlaps between DEGs and DMGs, and observed that biological processes significantly enriched the immune-related genes (i.e., our hypermethylated and down-regulated gene group). Hypermethylated and hypomethylated regions of thalassemia-related genes exhibited different distribution patterns. We thus, further identified and validated thalassemia-associated DMGs and DEGs by multi-omics integrative analyses of DNA methylation and transcriptomics data, and provided a comprehensive genomic map of thalassemia that will facilitate the exploration of the epigenetics mechanisms and pathogenesis underlying thalassemia.

Abstract
Thalassemia management has undergone significant development with the advancement in iron chelation therapy, which has led to a prolonged life expectancy. This has been accompanied by the emergence of several new morbidities and chronic diseases, including cancer. Over the years, multiple cases of solid and hematologic malignancies in thalassemia patients have been reported in the literature, with no clear mechanism for the development of cancer in these patients despite a number of potential mechanisms. However, the results of many studies have been contradictory regarding the risk of development of malignancies in thalassemia. The present review aims to discuss the available data on cancer and thalassemia in the literature, with the latest updates regarding possible malignancy development mechanisms, risks, and the most commonly reported types.

Abstract
Background: Thalassemia is a common inherited hematological disease with genetic disorders characterized by imbalanced synthesis of the globin chains. Due to the improvement of treatment methods, patients with thalassemia can survive for a long time. Therefore, it is not uncommon for patients with thalassemia suffering from malignant tumors. However, there are quite few reports on thalassemia patients complicated with breast cancer. Herein, we try to investigate the prevalence and genetic disorders spectrum of thalassemia in patients with breast cancer. Methods: Blood routing tests and serum ferritin analysis were conducted in 1887 breast cancer patients treated in the department of radiation oncology during 1 April 2020 and 30 March 2022. The suspected thalassemia carriers with small mean corpuscular volume (MCV), mean corpuscular hemoglobin content (MCH) or mean corpuscular hemoglobin concentration (MCHC) but the concentration of serum ferritin within normal limits were further investigated by polymerase chain reaction (PCR) and flow through hybridization gene chip to detect common mutations of α-globin and β-globin genes using Thalassemia Geno Array Diagnostic Kit. The prevalence and genetic mutation spectrum of thalassemia among breast cancer patients were analyzed. Results: Four hundred and eighty-nine suspected thalassemia carriers were detected by complete blood cell counts and serum ferritin analysis among 1887 breast cancer patients. One hundred and seven cases (5.7%) were identified as carriers of thalassemia, of which 55 cases (51.4%) were α-thalassemia, 50 cases (46.7%) were β-thalassemia, and 2 cases (1.9%) were co-inheritance of α-thalassemia and β-thalassemia simultaneously. In α-thalassemia, the most prevalent genotype is -SEA/αα; as for β-thalassemia, βIVS-II-654/β is the most common genotype. The degree of anemia is more severe in β-thalassemia than in α-thalassemia. Conclusion: This is the first comprehensive molecular epidemiological investigation on thalassemia among breast cancer patients. Our data indicated that thalassemia was not uncommon in breast cancer patients. The physicians should have the knowledge to avoid misdiagnosis as iron deficiency anemia.

Review and Recommendations on Management of Adult Female Thalassemia Patients with Hypogonadism based on Literature Review and Experience of ICET-A Network Specialists. Mediterr J Hematol Infect Dis 2017; 9:e2017001. [PMID: 28101307 PMCID: PMC5224811 DOI: 10.4084/mjhid.2017.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2016] [Accepted: 11/14/2016] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Multi-transfused thalassemia major (TM) patients frequently develop severe endocrine complications, mainly due to iron overload, anemia, and chronic liver disease, which require prompt diagnosis, treatment and follow-up by specialists. The most common endocrine complication documented is hypogonadotropic hypogonadism which increases with age and associated comorbidities. It is thus important for physicians to have a clear understanding of the pathophysiology and management of this disorder. Also to be aware of the side effects, contraindications and monitoring of sex steroid therapy. In this paper, practical ICET-A recommendations for the management of hypogonadism in adult females with TM are addressed. METHODS In March 2015, the Coordinator of the International Network of Clinicians for Endocrinopathies in Thalassemia and Adolescent Medicine (ICET-A) conducted a two-step survey to assess the attitudes and practices of doctors in the ICET-A network taking care of adult female TM patients with hypogonadism. They were clinically characterized by the absence of pubertal development or discontinuation or regression of the maturation of secondary sex characteristics, and biochemically by persistent low FSH, LH and estradiol levels. Recently a supplementary survey on adult female hypogonadism in TM was undertaken within the ICET-A network. RESULTS The completed questionnaires were returned by 16 of 27 specialists (59.2%) following 590 female TM patients over the age of 18 years; 315 patients (53.3%) had hypogonadism, and only 245 (74.6%) were on hormone replacement therapy (HRT). Contraceptive oral pills (COC) were the first treatment choice in 11 centers (68.7%). A wide range of COCs was used with different progestin contents. In general, the patients' compliance to treatment was reported as good in 81.2 % of centers. The frequency of required tests for follow-up HRT, in addition to the regular check-up for thalassemia, was variable in the participating centers. CONCLUSIONS Doctors taking care of TM patients should have sound knowledge of the pathophysiology of hypogonadism in adult females with TM. They should know the potential effects of HRT including advantages and disadvantages of estrogen and progestins. Moreover, they should keep in consideration the emotional needs of these patients dreaming of attaining a full pubertal development.

Abstract
Significant improvements in therapy and life expectancy of β-thalassemia patients in last decades result in the need of commitment for gynecologists and obstetricians as the complexity of organ impairment needs a specific multidisciplinary approach. After a review of clinical manifestations of β-thalassemia from a gynecologic point of view, we present the experience of a gynecologic center in treating β-thalassemia patients from more than 20 years.
