RESUMO

Introduction: To evaluate the effect of early chelation therapy (≤ 3 years) with a variety of chelating agents on age at menarche and menstrual characteristics in patients with transfusion-dependent thalassemia (TDT). Design: A retrospective multicenter study promoted by the International Network of Clinicians for Endocrinopathies in Thalassemia and Adolescent Medicine (ICET-A). Setting: Eight of 13 International Thalassemia Centers (61.5%) in the ICET-A Network participated. Patients: Fifty-seven female TDT patients, aged 11 to 26 years, and with early iron chelation therapy, were eligible for the present study. They were enrolled from one center from Iran (33 patients), 3 centers from Bulgaria (9), 1 from Greece (8), one from Oman (4), 1 from Cyprus (2), and 1 from Italy (1). Seven patients were excluded, four still prepubertal (age 12-14 years) and 3 with primary amenorrhea. Therefore 50 patients were finally enrolled. Results: All fifty TDT patients developed spontaneous menarche at a mean age of 14.2 ± 2.24 years (range 9 - 20). A significant positive correlation was observed between age at menarche and serum ferritin levels (r: 0. 41, p=0.005). Regular menstrual cycles were reported from 32 (64%) patients, of whom 28 (83.3%) get menarche at age ≤ 14 years. Complications were more frequent in patients older than 14 years at menarche and in those with secondary amenorrhea. Conclusions: Age at menarche greater than 14 years was a forerunner of menstrual irregularities and associated complications in 36% of patients despite precocious chelation therapy. The poor adherence to treatment, to be demonstrated in future studies, could explain the finding.

RESUMO

Mucormycosis, caused by the widespread molds of the Mucorales order, is an insidious infection that manifests in different clinical forms. Even the most benign form, the cutaneous mucormycosis, can present with severe complications and a fatal outcome in patients with a suppressed immune system and underlining comorbidities. We present a rare case of a proven primary multifocal cutaneous mucormycosis in a child with newly diagnosed acute leukemia without multiorgan dissemination. Various laboratory techniques (histopathological, cultural and molecular-genetic) were used to detect and confirm the diagnosis. Etiological therapy (liposomal amphotericin B, 5 mg/kg) combined with surgical intervention were used to manage the infection. The case shows that a rapid and complex diagnostic approach is of crucial importance for the timely initiation of adequate therapy, as well as for the successful management of this life-threatening fungal infection.

RESUMO

Due to the recent alarming increase in the incidence of hepatocellular carcinoma (HCC) in thalassemias, the present report reviews briefly the frequency, the major risk factors, and the surveillance of HCC in ß-thalassemias. Over the past 33 years, 153 cases of HCC were reported in patients with thalassemia, mainly in Italy and Greece. Among HCV-infected patients, additional factors promoting the development of HCC included: advanced age, male sex, chronic hepatitis B (CHB) co-infection, and iron overload. For early diagnosis of HCC, sequential ultrasound screening is recommended especially for thalassemia patients with chronic hepatitis C (CHC), which coincides with (one or more) additional risk factors for HCC. Here we report also the preliminary data from thalassemic patients, above the age of 30 years, followed in 13 ICET-A centers. The total number of enrolled patients was 1,327 (males: 624 and 703 females). The prevalence of HCC in thalassemia major patients [characterized by transfusion-dependency (TDT)] and thalassemia intermedia [characterized by nontransfusion dependency (NTDT)] was 1.66 % and 1.96 %, respectively. The lowest age at diagnosis of HCC was 36 years for TDT and 47 years for NTDT patients. We hope that this review can be used to develop more refined and prospective analyses of HCC magnitude and risk in patients with thalassemia and to define specific international guidelines to support clinicians for early diagnosis and treatment of HCC in thalassemic patients.

RESUMO

BACKGROUND: More than five decades ago, thalassemia major (TDT) was fatal in the first decade of life. Survival and quality of life have improved progressively thanks to the implementation of a significant advance in diagnostic and therapeutic methods, consisting mainly of a frequent transfusion program combined with intensive chelation therapy. Improvement also includes imaging methods used to measure liver and cardiac iron overload. Improved survival has led to a growing number of adults requiring specialised care and counselling for specific life events, such as sexual maturity and acquisition of a family. AIMS OF THE STUDY: The main aim is to present the results of a survey on the marital and paternity status in a large population of adult males with TDT and NTDT living in countries with a high prevalence of thalassemia and a review of current literature using a systematic search for published studies. RESULTS: Ten out of 16 Thalassemia Centres (62.5%) of the ICET-A Network, treating a total of 966 male patients, aged above 18 years with ß- thalassemias (738 TDT and 228 NTDT), participated in the study. Of the 966 patients, 240 (24.8%) were married or lived with partners, and 726 (75.2%) unmarried. The mean age at marriage was 29.7 ± 0.3 years. Of 240 patients, 184 (76.6%) had children within the first two years of marriage (2.1 ± 0.1 years, median 2 years, range 1.8 - 2.3 years). The average number of children was 1.32 ± 0.06 (1.27 ± 0.07 in TDT patients and 1.47 ± 0.15 in NTDT patients; p: >0.05). Whatever the modality of conception, 184 patients (76.6%) had one or two children and 1 NTDT patient had 6 children. Nine (4.8%) births were twins. Of 184 patients, 150 (81.5%) had natural conception, 23 (12.5%) required induction of spermatogenesis with gonadotropins (hCG and hMG), 8 (4.3%) needed intracytoplasmic sperm injection (ICSI) and 3 adopted a child. 39 patients with TDT and NTDT asked for medical help as they were unable to father naturally: 7 TDT patients (17.9%) were azoospermic, 17 (37.7%) [13 with TDT and 4 with NTDT] had dysspermia and 15 (33.3%) [13 with TDT and 2 with NTDT] had other "general medical and non-medical conditions". CONCLUSIONS: Our study provides detailed information in a novel area where there are few contemporary data. Understanding the aspects of male reproductive health is important for physicians involved in the care of men with thalassemias to convey the message that prospects for fatherhood are potentially good due to progressive improvements in treatment regimens and supportive care.

RESUMO

We report on a rare case of a 3-year-old boy with B-cell acute lymphoblastic leukemia (B-ALL), which was characterized simultaneously with two different fusion transcripts: ETV6-RUNX1 and BCR-ABL1 (e1a2). The patient presented with fever, diarrhea, normal white blood cell counts of 5.9×10(9)/L without circulating abnormal cells, anemia, and thrombocytopenia, as well as an enlarged liver without splenomegaly. The bone marrow was markedly hypercellular with a total infiltration of agranular lymphoid blast cells with a B-II (pre-B) lymphoblastic phenotype: cyCD79α(+), CD19(+), sCD22(+), CD10(+), CD20(-), CD34(+), and sIgM(-), with dim aberrant co-expression of the myeloid-associated markers CD13(+) and CD33(+). Conventional cytogenetic analysis was unsuccessful; however, molecular analysis revealed the BCR-ABL1 (p190) and ETV6-RUNX1 transcripts. A diagnosis of BCR-ABL1 (p190)-positive and ETV6-RUNX1-positive B-ALL was made, and treatment was initiated according to the AIEOP-BFM-ALL2000 protocol. A complete remission was achieved after the first induction course of chemotherapy. Twelve months after the diagnosis, the child is alive with levels of residual disease of <0.05% estimated both by 8-color flow cytometry and real-time quantitative reverse transcription polymerase chain reaction.
