Zinc deficiency plays an important role in many thalassemia-related complications like growth retardation, hypogonadism and delayed puberty which are frequently noted in adolescent age. Although zinc is supplemented to thalassemic patients visiting Day Care Center, Yangon Children Hospital (YCH), Myanmar, a report concerning serum zinc level of these patients is still lacking. This study, therefore, aimed to assess serum zinc status in thalassemic adolescents attending Day Care Center, YCH. Materials and Methods: This hospital-based cross-sectional study was conducted on 99 thalassemic adolescents. Mean age of diagnosis was 5.1±2.1 years. Non-fasting serum zinc concentration was determined by atomic absorption spectrophotometry. According to National Health and Nutrition Examination Survey data, zinc deficiency was defined as serum zinc concentration < 66 μg/dL (female) and < 70 μg/dL (male). Results: Serum zinc concentration (μg/dL) was 57.35 (47.30-80.14) (median, interquartile range) with maximum, 195.05 and minimum, 28.83. Zinc deficiency was observed in 69.7% (69 out of 99; 35 males and 34 females) of the patients. The associations of zinc deficiency with gender, phenotype and the use of chelator were nonsignificant (P>0.05). Conclusion: In spite of zinc supplementation, nearly 70% of the thalassemic adolescents showed zinc deficiency. Zinc deficiency in these adolescents might not be related to gender, phenotypes or the use of chelator. Poor compliance to take zinc supplementation and/or irregular blood transfusion could partly be attributable to zinc deficiency in these adolescents. Providing health education on the importance of regular intake of adequate zinc is advisable and periodic evaluation of zinc levels is recommended for thalassemic adolescents.","PeriodicalId":44212,"journal":{"name":"Iranian Journal of Pediatric Hematology and Oncology","volume":"11 1","pages":"11-17"},"PeriodicalIF":0.3,"publicationDate":"2020-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44530056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pulmonary hypertension (PH) is one of the cardiopulmonary morbidities with high mortality that, if not treated, may trigger right-sided heart failure and premature death. PH is defined as a mean pulmonary artery pressure of ≥25 mmHg at rest or ≥30 mmHg during exercise. The prevalence of PH is known to be higher in TI than in TM. Moreover, the pathophysiology of PH in thalassemia appears to be sophisticated and complex. Risk factors for occurrence of PH consists of non-transfusion dependent thalassemia (NTDT), sub-optimally transfused transfusion dependent thalassemia (TDT), splenectomy, thrombocytosis, anemia, NRBC ≥ 300 × 106, iron accumulation, history of thrombosis and older age. Other parameters which aggravate the risk of PH include hemolysis, oxidative stress, hypoxemia, alteration of erythrocyte membrane, decline of nitric oxide biological availability, arginine abnormal regulation and arginase excess. The screening method for PH is Doppler echocardiography but the gold standard for detection of PH is right heart catheterization (RHC). Current medical therapeutic options in PH comprise hydroxyurea, LCarnitine, sildenafil, calcium channel antagonists, endothelin 1-receptor blockers and prostacyclin agonists. The only curative surgical method for the refractory and severe cases of PH is pulmonary endarterectomy. In this article, the etiology, pathophysiology, diagnostic methods and novel therapies of thalassemia associated PH are discussed.","PeriodicalId":44212,"journal":{"name":"Iranian Journal of Pediatric Hematology and Oncology","volume":"11 1","pages":"51-63"},"PeriodicalIF":0.3,"publicationDate":"2020-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44254100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monocytes shift from conducting intercellular communication to becoming innate immune function as a response. This study aims to examine the influence of zinc status on the monocyte phagocytosis in patients with major beta-thalassemia. Materials and Methods: This study was a randomized-placebo-controlled trial. The patients were randomly assigned into either the zinc-treated group using zinc gluconate 50mg daily or the placebo group. Analysis is based on the 12-weeks observation of the complete blood count, plasma zinc level, and phagocytosis level of monocytes. The phagocytic activity of monocytes was measured using atomic absorption spectroscopy (AAS) or x-ray fluorescence (XRF). The comparisons of the data within each group were analyzed using Mann-Whitney test. Results: The results indicated no significant differences in patients’ characteristics; the level of plasma zinc at week 12 in the zinc-treated group (67.41+14.4) was significantly higher than the placebo group (54.37+9.38) (p=0.047). The phagocytosis levels of monocyte at week 12 in zinc-treated group (8.70+4.61) were higher than the placebo groups (8.23+4.22) (p=0.002). The ferritin level of zinc-treated group was higher than placebo group (p=0.084), while high level of ferritin is associated with higher level of monocyte phagocytic activity, the result is statistically significant (p=0.002). The results also showed that higher level of plasma zinc insignificantly correlates with lower phagocytic activity of the monocytes (p=0.059). Conclusion: The immune mechanisms in response to zinc-deficient environment underlying the shifting between adaptive to innate immune response involves multiple molecular components of the immune system and have been attributed to specific features of -thalassemia, in which overall immune activity is decreased even though the phagocytic activity of monocytes is increased.","PeriodicalId":44212,"journal":{"name":"Iranian Journal of Pediatric Hematology and Oncology","volume":"11 1","pages":"24-29"},"PeriodicalIF":0.3,"publicationDate":"2020-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42435269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, sensitive biomarkers of renal tubular injury are needed to detect AKI earlier. In this study, urinary beta 2-microglobulin (β2-MG) and urinary N-acetyl-β-D-glucosaminidase (NAG) were evaluated for AKI prognosis/diagnosis in pediatric patients suffering different cancers prescribed with Ifosfamide, Ifosfamide plus Carboplatin, and Ifosfamide plus Cisplatin. Materials and Methods: In this prospective study done in Isfahan, Iran, urinary β2-MG, urinary NAG, blood urea nitrogen (BUN), and serum and urinary creatinine (Cr) were measured in 40 pediatric cancer patients less than 16 years old in three age groups during 61 courses of chemotherapy on day 0, three and six after the treatment. Results: Using ANOVA and t-test, the mean levels of urinary β2-MG (p= 0.001), urinary β2-MG/Cr (p= 0.003) and urinary NAG/Cr (p= 0.001), before and on day six of the treatment were statistically significant (p< 0.05). Also, the mean levels of BUN (p= 0.01), urinary β2-MG (p= 0.001), β2-MG/Cr (p= 0.001) and NAG/Cr (p= 0.004) based on the gender groups, the mean levels of urinary NAG (p=0.001), NAG/Cr (p= 0.001) and β2-MG/Cr (p= 0.008) based on three age groups, and the mean levels of serum Cr (p= 0.047), urinary β2-MG (p= 0.005), β2-MG/Cr (p= 0.032) and NAG/Cr (p= 0.032) based on the Ifosfamide dosage were statistically significant during the time of the treatment.
