RESUMEN

BACKGROUND: Thalassemia is one of the most common genetic disorders. Patients with beta-thalassemia major confront serious clinical and psychosocial challenges in their all lives, which require coping strategies. It appears that psychological interventions are necessary to improve their coping skills. The aim of this study was to determine the effect of applying emotional intelligence components on coping strategies in adolescents with beta- thalassemia major. METHODS: This randomized clinical trial study involved 60 teenagers with beta- thalassemia major who were divided equally into intervention and control groups. The experimental group participated in 9 sessions of an emotional intelligence program consisting of 90 min, held both virtually and in person, two sessions per week. We investigated problem-focused and emotion-focused (including positive emotion-focused and negative emotion-focused) coping strategies of both groups of adolescents using the Billings and Moos questionnaire before the intervention, immediately after the intervention, and one month after the intervention. Data were analyzed using SPSS 21. Then, according to the research objectives, independent t-tests, Chi-square, Mann-Whitney, repeated measures Analysis of Variance (ANOVA) and Bonferroni test were used. RESULTS: In experimental group, the mean score of problem-focused (problem-solving, cognitive evaluation) and positive emotion-focused (social support) coping increased from (14.2 ± 2.6) and (5.0 ± 0.5) before the intervention to (29.6 ± 3.1) and (10.9 ± 1.3) one month after the intervention, respectively (P < 0.001). However, the mean score of emotional inhibition and somatic inhibition (negative emotion-focused) decreased from (13.8 ± 1.7) and (6.7 ± 1.5) before the intervention to (8.6 ± 2.0) and (3.8 ± 1.8) one month after the intervention, respectively (P < 0.001). While the mean score of problem-focused and emotion-focused coping strategies before and one month after the intervention remained stable in the control group. CONCLUSIONS: Adolescents with beta-thalassemia suffer from psychosocial disorders and they also cope maladaptive with their illness. Applying emotional intelligence has improved their coping strategies. Caregivers should be encouraged to assess coping skills in teenagers with beta-thalassemia major and use methods such as emotional intelligence to improve them. Therefore, it can help these adolescents to deal effectively with stress and complications of the disease. TRIAL REGISTRATION NUMBER: IRCT20210521051356N1 (17/06/2021).

RESUMEN

Iron overload is the main cause of morbidity and mortality in ß-thalassemia major patients, and cardiac iron overload is the most common reason for death in these transfusion-dependent patients. Hepcidin, a liver-derived peptide hormone, plays a key role in plasma iron levels regulation by controlling two main stages, digestive iron absorption in enterocytes, and iron recycling in macrophages. Although hepcidin is mainly secreted from hepatocytes in the liver, it is also synthesized from mononuclear cells consisting of monocytes and lymphocytes. Binding of this molecule to ferroportin, a specific cellular exporter of iron, leads to degradation of the ligand-receptor complex, which reduces the iron overload by lowering the amounts of iron released into the plasma. Likewise, the same mechanism has been proved to be true for lymphocyte-drived hepcidin. The expression levels of hepcidin mRNA were evaluated using quantitative real time PCR (qRT-PCR) in 50 ß-thalassemia major patients, as well as 25 healthy volunteers as the group of control. There was a significantly positive correlation between the cardiac iron concentration, showed by higher T2 values, and hepcidin levels in the patients (p = 0.028; r = 0.311). However, hepcidin expression levels did not significantly correlate with ferritin and liver iron concentrations. Hepcidin can act as a beneficial marker to determine iron overload degrees, particularly in the heart, in ß-thalassemia major patients and be used as a logical therapeutic agent for treatment of ß-thalassemia disorders.

RESUMEN

INTRODUCTION: Radiocolloids labelled with less costly and more accessible radionuclides such as rhenium-188 are of interest to developing countries compared with those labelled with rhenium-186 and yttrium-90. AIM: This study was aimed to evaluate the efficacy and safety of radiosynovectomy using rhenium-188 in patients with chronic haemophilic synovitis and recurrent hemarthrosis. METHODS: In this quasi-experimental prospective study, 20 haemophilic patients were evaluated at preinjection, and at 1, 3, 6 and 12 months after injection. Magnetic resonance imaging (MRI) was done to measure synovial thickness and to calculate Denver score. Joint radiographs were taken to measure the Pettersson score. The Gilbert questionnaire, Functional Independence Score in Hemophilia (FISH) and visual analogue scale (VAS) for pain were completed, and the number of bleeding episodes and factor consumption were recorded at each follow-up visit. RESULTS: The number of bleeding episodes, the amount of factor consumption per month, VAS pain scores and synovial thickness decreased significantly over time (P < .05). Gilbert and FISH scores showed significant improvement (P < .001). However, Pettersson score and Denver score showed no significant changes after injection. Minor complications including temporary pain and swelling occurred in 20% of patients, and no major complication was observed after rhenium-188 injection. CONCLUSION: Our results indicated high clinical impact, efficacy, safety and low invasion of rhenium-188 in radiosynovectomy of haemophilic patients. Considering the availability and relatively low cost of rhenium-188 in developing countries, this can be a good treatment option for haemophilic patients with recurrent hemarthrosis, particularly when the synovial hypertrophy is not massive yet.

RESUMEN

BACKGROUND AND OBJECTIVE: ß-thalassemia results from a diverse range of mutations inside the hemoglobin subunit ß (HBB) gene. In a study of ß-thalassemia carriers and some of their at-risk fetuses in the Khorasan province of Iran, we aimed to recognize the most common mutations in the region. We also investigated a possible link between these mutations and some of the relevant hematological indices. METHODS: Amplification-refractory mutation system-PCR (ARMS-PCR) was used to detect the typical HBB mutations among 1593 individuals, suspected of having a mutated HBB allele from March/2011 to January/2018. Sanger sequencing of HBB had been performed, where ARMS-PCR was uninformative. In some cases, reverse dot blot was utilized. Analysis of variance was used to compare parametric variables. RESULTS: Among 1273 ß-thalassemia carriers, the prevalence of the mutations were reported as follows: IVS-I-5 (42.03%), IVS-II-1 (11.23%), codons 8/9 (4.79%), codon 44 (4.56%), codon 15 (3.53%), Los Angeles (2.91%), codon 5 (2.75%), IVS-I-110 (2.51%), -88 (2.20%) and other mutations were less than 2% of all of the reported mutations. 644 conceptions were subjected to prenatal diagnosis, using chorionic villus sampling. 118 cases were reported as normal. 352 cases were detected as carriers. 174 cases were diagnosed as affected. There was a significant difference in mean corpuscular volume and hemoglobin A2 levels between the nine most commonly reported mutation types (p<0.001). CONCLUSION: This study makes a reliable guide for ß-thalassemia diagnosis in the region. The possibility of a correlation between HBB mutations and hematological indices opens a gate of future investigations.

RESUMEN

BACKGROUND Hepatitis C virus (HCV) is considered to be the major cause of post-transfusion hepatitis in patients with thalassemia. We aimed to determine the HCV prevalence, genotypes, and viral load among patients with major ß-thalassemia in Mashhad, Iran. METHODS Medical records of all 550 patients with major ß-thalassemia who referred to ThalassemiaHemophilia Center of Mashhad (Sarvar Clinic) were reviewed from October to November 2011. Plasma samples of the patients were tested for the presence of anti-HCV antibodies by enzyme linked immunosorbent assay. Real-time polymerase chain reaction (PCR) was used to determine viral genotype and HCV RNA titer. RESULTS HCV antibodies were detected in 37 individuals (6.73%) including 17 men and 20 women with mean age of 25.2 ± 8.4 years. The PCR analysis was performed for 27 patients, of whom HCV RNA was detected in 17 patients (63.0%). Viral titers were investigated in 14 subjects and a high viral load more than 600000 copies/mL was observed in 6 patients (42.9%). The most prevalent genotypes were 3a (50.0%) followed by 1a (37.5%). No significant correlation was found between genotype and age, sex, serum ferritin, liver tests, and HCV RNA titer. CONCLUSION HCV infection among patients with thalassemia is more common than general population in Mashhad, northeast Iran. The dominant HCV subtype is 3a followed by 1a. These findings could help health authorities to provide preventive measures, and practitioners to choose the right protocol of treatment for the patients.

RESUMEN

Accumulation of excess iron in heart can lead to cardiac dysfunction, which is the most common cause of death in thalassemia major patients. Biopsy is an invasive procedure and therefore not an ideal option to assess iron load. However, standard/usual non-invasive methods, such as ferritin measurement, have some limitations and the results show poor correlations with iron load. Magnetic Response Imaging (MRI-T2*), as a non-invasive and reliable method for iron load assessment in organs such as liver and heart, can be suggested as a favorable alternative. This cross-sectional study was implemented in Thalassemia and Hemophilia Clinic Center (Sarvar) affiliated with Mashhad University of Medical Sciences, Mashhad, Iran, from 2012 to 2013. After the approval of the research protocol by the local ethic committee, laboratory tests, including CBC and serum ferritin, were carried out, and echocardiography and heart and liver MRI-T2* were performed. All statistical analysis was done through SPSS software (version 11.5), using independent sample t test and Pearson's correlation coefficient test. A P value ≤0.05 was considered to be significant. 88 patients with the mean (±SD) age of 21.2 (±5.6) years, (range 11-37 years) were observed. Iron load was assessed using MRI-T2* with the following results: Out of 88 patients, 48.9 % had mild to severe cardiac siderosis, and 75.2 % had mild to severe liver siderosis. We demonstrated a correlation between liver MRI-T2* and serum ferritin, and heart MRI-T2* and ejection fraction. However, no correlation between liver and heart MRI-T2* was observed. Heart and liver siderosis is a common and serious problem in thalassemia major patients, and MRI-T2* as a sensitive and non-invasive technique can be used for early/timely detection of siderosis and good therapeutic monitoring in these patients.

RESUMEN

BACKGROUND: There are various clinical symptoms of thalassemia intermedia, and they lie roughly between those of major and minor forms of the disease. Patients with thalassemia intermedia occasionally require blood transfusions. This renders them susceptible to pulmonary arterial hypertension (PAH) syndrome, which is one of the most significant complications in patients with thalassemia intermedia. PAH is more common in in thalassemia intermedia than in thalassemia major, and it may cause cardiac complications in patients who are older than 30. The objective of this study was to estimate the prevalence of PAH in thalassemia intermedia patients so that they can be referred expeditiously for treatment, thereby preventing the complications that occur later. METHODS: This cross sectional study was conducted under the supervision of hematology department of Mashhad Medical University. Forty-one patients with thalassemia intermedia were examined at the Sarvar Thalassemia and Hemophilia Clinic of Mashhad. Electrocardiography, chest radiography, and echocardiography tests were performed for all of the patients by the same pediatric cardiologist. The data were processed by SPSS software, version 11.5, and the results were analyzed using chi-squared, Student's t, and Mann-Whitney tests. RESULTS: The mean age of the patients was 21.93±8.34. They had been under pediatric heart specialists' constant examination and treatment since their childhood when they were diagnosed with TI, and continue to receive regular follow-up care. The prevalence of pulmonary hypertension was 24% in our study population. In patients with thalassemia intermedia, the left ventricular (LV) mass indices were about 3-5 times higher than would be expected in a normal population. Patients with higher LV mass indices have a greater risk of developing pulmonary hypertension, and those with serum ferritin levels below 1000 ng/ml are less susceptible to diastolic dysfunction. CONCLUSION: Pulmonary hypertension is common in patients with thalassemia intermedia. Irregular chelation therapy or absence of this treatment might lead to diastolic dysfunction, and serum ferritin levels below 1000 ng/ml could be an important factor in preventing the development of diastolic dysfunction or slowing down its progression.

RESUMEN

Uncontrolled recurrent hemarthrosis can end to contracture, deformity, pain, joint destruction and gait disorders which are disabling. We are going to report a challenge, a unilateral knee flexion contracture in a child with severe hemophilia A and inhibitor who underwent different treatment options with unsatisfactory improvement of knee range of motion. Mismanaging postoperatively, patient and parents irresponsibility in managing self-care, lack of access and affordability to treatment and unavailability of proper treatment can be the reasons of recurrence in addition to the tough nature of a patient with inhibitor.

RESUMEN

BACKGROUND: Identification of blood group antigen frequencies in a population has various benefits in transfusion medicine. Most data in the literature include frequencies of these antigens in European and American countries. In this study for the first time we have reported frequencies of these antigens in the northeast of Iran. MATERIALS AND METHODS: Blood group antigens were characterized in the 522 blood donors in Mashhad, Iran. The following antigens including ABO, Rh (D, C, E, c, e), MNSs (M, N, S, s), Lutheran (Lu(a), Lu(b)), P (P, P(1)), Kell (K, k, Kp(a), Kp(b)), Lewis (Le(a), Le(b)), Duffy (Fy(a), Fy(b)) and Kidd (Jk(a), Jk(b)) were typed and phenotypes frequencies were expressed as a percentage. RESULTS: In the ABO blood group, the most common phenotype was O (33.9%) followed by A, B and AB. In the Rh blood group, the most common antigen was e (97.9%) and R(1)r (31.8%) being the most common phenotype. The most common phenotypes for MNSs, P, Lu and Kell blood group were M+N+, S-s+, P(1), Lu (a-b+), K-k+ and Kp (a-b+). A very rare phenotype of Lu (a-b-) was also observed in 2.7% of cases. We found rare phenotypes of Le (a+b+) and Fy (a-b-) in 7.9% and 3.4% of subjects, respectively. CONCLUSION: We determined some differences in phenotype frequencies of blood group compared with other studies. We found higher frequencies of B blood group and also more frequencies of some rare phenotypes, Lu (a-b-), Le (a+b+) and Fy (a-b-).

RESUMEN

PURPOSE: To determine risk factors (RFs) and their relationship with life-threatening infection (LTI) in children with febrile neutropenia (FN). METHOD: In this cross-sectional study, from December 2008 to November 2009, all children with FN admitted to Dr Sheikh Pediatric Hospital were enrolled. For each patient, demographic, clinical, and laboratory data were recorded and they were followed up for occurrence of LTI. RESULTS: One hundred and twenty episodes of FN in 68 patients were analyzed. The most common underlying disease was acute lymphoblastic leukemia (53.3%), 9 (7.5%) died from an infection and 35 patients (29.1%) had a LTI. Five variables were identified as RFs for LTI, that is, body temperature ≥39°C (P=0.000), presence of mucositis (P=0.000), abnormal chest x-ray (P=0.001), platelet count <20,000/mm (P=0.000), and absolute neutrophil count <100/mm (P=0.001). Risk of LTI was increasing according to number of RFs presented at the beginning of admission (from 2.8% in patients without RF to 100% in patients with 5 RF). Data mining analysis showed relationship between RFs with platelet count as the most important variable in the high-risk group for LTI. CONCLUSIONS: Evaluation of important RFs and judging the severity of patients' condition by studying the importance and relationship between RF at the time of admission can be a useful method for screening LTI in children with FN.

RESUMEN

BACKGROUND: Thalassemia is a common hemoglobin disorder in Iran and one of the major public health problems. Although blood transfusions are lifesavers for thalassemia patients, they may be associated with some complications especially erythrocyte alloimmunization. The purpose of this study was to investigate the prevalence of red blood cell alloantibodies and to determine types of these antibodies among multiple-transfused thalassemic patients. MATERIALS AND METHODS: A total of 313 thalassemia patients in the northeast of Iran, who received regular blood transfusion, were included in this study. Screening of antibodies was performed on fresh serum of all patients and then antibodies were identified in patients' serum that had positive antibody screening test using a panel of recognized blood group antigens. RESULTS: We identified 12 alloantibodies in 9 patients (2.87%) that all were against Rhesus (Rh) blood group antigens (D, C, E). Three patients developed 2 antibodies, and others had one antibody. The most common alloantibodies were Anti-D (88.88%) and followed by Anti-C and Anti-E. Higher frequency of alloimmunization was observed in female, Rh negative and splenectomized patients. CONCLUSION: This study showed that evaluation of the packed cells for Rh (C, E) from the start of transfusion can be helpful in decreasing the rate of alloantibody synthesis.

RESUMEN

Individuals with severe haemophilia A may be at risk for reduced bone mineral density because of reduced weight-bearing exercise and hepatitis C infection. For confirming the reduced bone density, in the current cross-sectional study, we tried to address bone mineral density in individuals with severe haemophilia A and surveyed the relation of reduced bone density with hepatitis C viruses. To fulfil these aims, bone density and biochemical indexes in 18 individuals with severe haemophilia A and also in 18 individuals matched for age, sex, weight and height, as the control group, were examined. The obtained results showed that individuals with severe haemophilia A had reduced bone density (1.136 +/- 0.118, 0.801 +/- 0.238) in lumbar and femur regions, respectively, in comparison with the age- and sex-matched group (1.299 +/- 0.237, 1.458 +/- 0.505). The major complications of coagulation disorders are various types of excessive bleeding. The current study describes an association between severe haemophilia A and osteopenia, specifically at both the femur and the lumbar spine.

RESUMEN

Tumor-induced hypercalcemia is a frequent complication of advanced cancers, but it has been rarely reported in patients with sarcoma. We report a 16 year-old boy presenting with polyuria, polydipsia and severe dehydration. Laboratory examination revealed severe hypercalcemia (serum calcium 23 mg/dl) which caused emaciation and was accompanied by low serum phosphorus and suppressed parathyroid hormone. Diagnostic imaging revealed a huge anterior mediastinal mass. Hypercalcemia was successfully treated with pamidronate, a bisphosphonate, and the patient underwent surgical resection. Pathological and immunohistochemical analyses confirmed a diagnosis of biphasic synovial sarcoma. To our knowledge, this is the first case of mediastinal synovial sarcoma presenting with hypercalcemia.
