Pages 61-69IntroductionPreventing and starting early treatment of infections in patients whose immunity system is weak due to malignancies like leukemia can reduce mortality. This study aimed to determine microbial and antibiotic resistance patterns in clinical samples of patients with acute leukemia to start early treatment before the results of clinical tests are known.
Subjects andMethodsIn this cross-sectional study, the clinical samples of all patients hospitalized with the diagnosis of acute leukemia were cultured and their antibiogram was evaluated. Then, the data were analyzed by SPSS 18 based on the objectives of the study.ResultsOf a total of 2,366 samples, 18.95% were reported to be positive blood samples, 22.96% were reported to be urine samples and 36% wound samples. E. coli was the most common bacteria isolated from the blood and urine cultures (34% in blood, 32% in urine culture) while Staphylococcus aureus was the most common in the wound culture (35%).The highest level of sensitivity in the organisms with positive blood culture was to Ciprofloxacin, while in positive urine and wound culture was to Imipenem. The highest resistance in blood, urine and wound culture was to Cotrimoxazole.ConclusionAccording to results obtained from this study, it is necessary to conduct appropriate studies on this issue in specific conditions in our country. The findings of this study can be used in clinics for more accurate diagnosis, more effective treatment before the results of clinical tests are known and also for prevention of infection in cancer patients.Keywords: Acute leukemia, Antimicrobial susceptibility, Clinical fluids, Microbial profile -
Pages 70-78BackgroundMyeloproliferative neoplasms (MPNs) are clonal malignant diseases that represent a group of conditions including polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF). The aim of this study was to evaluate possible correlations between JAK2V617F allele burden and clinicohematologic characteristics in Iranian patients with MPNs. We also aimed at determining the correlation between JAK2V617F allele burden and use of cytoreductive treatment (hydroxyurea).Materials And MethodsWe performed ARMS-PCR for all MPNs samples and subsequently performed real-time quantitative polymerase chain reaction (qRT-PCR) for JAK2V617F allele burden measurement using DNA from peripheral blood leukocytes.ResultsTwo distinct groups of patients were examined at a single time point: group A (n=40; 20 PV, 20 ET) was examined at the time of diagnosis; group B (n=85; 40 PV, 30 ET and 15 PMF) while under treatment with hydroxyurea (HU). The median allele burden of the JAK2 V617F was 72% for PV and 49% for ET patients at the time of diagnosis (p=0.01). For patients with HU treatment, we determined the median JAK2V617F allele burden to be 43%, 40%, and 46.5 % in PV, ET and PMF patients; respectively. HU-treated PV patients had a significant lower %JAK2V617F than PV patients at the time of diagnosis (43% vs. 72%, p=0.005). In ET group, the relationship between the JAK2 V617F allele burden and leukocyte count was significant (p=0.02 and p=0.01 in untreated and treated patients, respectively).ConclusionsOur results showed that patients with PV have a higher JAK2V617F allele burden. Moreover, our study demonstrated that the JAK2V617F allele burden correlates with clinical features in ET group. We also showed hydroxyurea can affect the JAK2V617F allele burden in PV patients.Keywords: Hydroxyurea, JAK2V617F, Myeloproliferative neoplasms

Pages 79-84BackgroundIdiopathic thrombocytopenic purpura (ITP) is a chronic disease which is accompanied with hopelessness and loss of the sense of well-being due to its symptoms and treatment. It also affects patient's sense of social and spiritual well-being. This disorder decreases patient's self-esteem and their quality of life by changing their mental image and self-confidence. This study was performed to find the relationship between self-esteem and quality of life of patients with ITP.Materials And MethodsThis was a descriptive-analytical study on 64 patients with ITP who referred to Isfahan's Sayed Al-Shohada Hospital, Iran. In this study, patients with ITP were selected randomly using a random number chart. The data collection tools consisted of the World Health Organization Quality of Life (WHOQOL)-BREF and Coopersmith Self-esteem Inventory (CSEI). Data were analyzed using SPSS and chi-square and Mann-Whitney tests and the Pearson and Spearmans rank correlation coefficients.ResultsIn total, 64 patients completed the questionnaires. Results showed that 32% of subjects were over 36 years of age and 59% were women. In addition, 29.7% of ITP patients had low self-esteem and quality of life. Chi-square test showed a significant relationship between self-esteem and quality of life of patients with ITP.ConclusionsThe results of the present study showed that considerable attention must be paid to self-esteem, as one of the most important factors influencing the promotion of quality of life. Therefore, it is suggested that patients self-esteem be improved by the implementation of educational and psychological programs in order to decrease the consequences of poor quality of life.Keywords: Self, esteem, Quality of life (QOL), Idiopathic thrombocytopenic purpura (ITP), Nurse, Iran

Pages 85-91BackgroundGranulocyte Colony Stimulating factors (GCSF) are high cost agents commonly recommended for primary and secondary prophylaxis of chemotherapy-induced neutropenia and febrile neutropenia. GCSFs have been shown to be beneficial in some patient subgroups, although they are probably overused in clinical settings. The American Society of Clinical Oncology (ASCO) guidelines summarize current data on the appropriate use of CSFs. The objective of this study was to assess and audit the use of GCSF in a tertiary care center according to recommendation of ASCO guideline.MethodsA Retrospective observational study from November 2014 to June 2015 was performed on all patients prescribed with filgrastim in the large teaching hospital (Isfahan, Iran). Data was collected on demographics, indication, dosing regimen, duration of treatment, the Absolute Neutrophil Count (ANC) and patient outcome.Results91 patients were recorded over the period of the study. 63.7% of prescription complied with the ASCO guideline. Febrile neutropenia post chemotherapy/radiotherapy was the most common appropriate indication (29.3%) followed by primary prophylaxis (25.8%). Fourteen (32 %) patients showed ANC recovery in 1-3 days, and 16 (37%) within 4-7 days. Ten patients (23 %) showed no recovery. The overall mortality was 8 (8.8%) patients.ConclusionThis study revealed that at least one-third of prescribed GCSF was not in accordance with ASCO guideline. Considering the high cost of GCSF in our country and limitation of our resources, we proposed cost-effectiveness studies on GCSF treatment and also development of national guideline for optimizing GCSF use.Keywords: Granulocyte Colony Stimulating factor, Clinical Audit, Drug Utilization Review

Pages 92-98BackgroundPatients with β-thalassemia major (TM) develop iron overload through increased iron absorption and transfusional therapy and its the most important complication of TM. Thalassemia is common in coastal regions and lands with low altitudes. The aim of this study is to determine the effect of high and low altitude on serum ferritin and treatment requirement in two groups of β-thalassemia major (TM) patients.
Subjects andMethodsPatients were divided into two groups, the first group (No: 50) living at sea level (in the port of Bushehr, Iran) and the second group (No: 40) living at the altitude of 2061 m (in the city of Shahrekord, Iran). All patients clinical history, blood transfusion and laboratory tests including complete blood count and hemoglobin electrophoresis were reviewed.ResultsThere were no significant difference in ferritin levels, transfusion period and diabetes incidence of the two cities patients (P> 0.05). Patients cardiac function and liver condition were significantly better in patients of Bushehr (PConclusionOur result showed that some of clinical manifestations of patients in low altitude such as cardiac and liver condition were better. But it did not affect ferritin level probably due to transfusion and chelating therapy. Totally patients of Bushehr had better conditions and had longer survivals.Keywords: β thalassemia major, Ferritin level, Cardiac function, Altitude -
Pages 99-105IntroductionCytokines are a large group of proteins play a key role in inflammation. Down-regulation of pro-inflammatory cytokines has beneficial effect on heart function. Propranolol, as a non selective beta-adrenergic blocker, has been extensively used for treatment of many cardiovascular problems such as arrhythmias and heart malfunction. In addition anti-inflammatory effects of propranolol have been revealed. In this study the propranolol effect on T helper type 1 cytokine profile in human leukemic T cells has been assessed in vitro.Materials And MethodsHuman leukemic T cells (Molt-4 and Jurkat) were cultured in complete RPMI medium. The cells were then incubated with different concentrations of propranolol (0.03- 30 µM) in the presence or absence of PHA (10 µg/ml) for 48 hours. The supernatants of cell culture media were collected and used for cytokines assay.ResultsPropranolol significantly decreased the T helper type 1 cytokine profile [Interleukin-2 (IL-2) and Interferon- γ (IFN-γ)] production in PHA stimulated Molt-4 and Jurkat cells, after 48 hour of incubation time, dose-dependently compared to untreated control cells.ConclusionOur data showed a dose dependent inhibitory effect of propranolol on the IL-2 and IFN-γ production in human leukemic Molt-4 and Jurkat cells. The anti- inflammatory effect of propranolol reported by other investigators may be in part due to its suppressive effect on production of inflammatory cytokines such as IL-2 and IFN-γ. So, propranolol along with its chronic long-term usage in cardiovascular problems may have potential implication in treatment of inflammatory-based disorders.Keywords: Propranolol, Cytokines, Leukemic, T, cells

Pages 106-110Isolated extramedullary relapse of chronic myelogenous leukemia (CML) after allogeneic stem cell transplant is rare. There is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for CML. He was presented with per orbital edema and neurological deficit of lower extremities and a mass lesion was found on spinal cord imaging. No evidence of hematologic relapse was identified at that time by bone marrow histology or cytogenetic. The patient died 1 month later with a picture of pneumonia, left ventricular dysfunction and a cardiopulmonary arrest on a presumed underlying sepsis with infectious etiology. Granulocytic sarcoma should be considered in the differential diagnosis of mass lesions presenting after allogeneic bone marrow transplantation for CML, even if there is no evidence of bone marrow involvement.Keywords: Granulocytic sarcoma, Chronic myelogenous leukemia, Allogeneic stem cell transplantation

Pages 115-119Purpose of review: Triple negative breast cancers (TNBC) are associated with aggressive course, higher rates of visceral and central nervous system metastases and lower survival rate than hormone receptor positive. Once metastasis has occurred, a median survival was approximately one year. Currently, chemotherapy in TNBC is similar to other HER2 negative breast cancer; but in the near future it will revolutionize.
Recent findings and Summary: TNBCs are quite heterogeneous, based on biomarkers and genetic variations; a series of new drugs have been tried. In this article; platinum, anti-epigenetic drugs, PARP inhibitors, epidermal growth factor receptor inhibitor, Src family kinase inhibitor, antiandrogen, glycoprotein Non-metastatic Melanoma Protein (gpNMB) antibody, LHRH conjugated to cytotoxic drugs and inhibition of the PI3K/AKT/mTOR Pathway will be explained. What is the optimize therapy of patients with TNBC? It's still not clear but it seems that the road map according to biological and genetic markers is taking shape.Keywords: Triple negative breast cancers, PARP inhibitors, Non, metastatic Melanoma Protein, Src family kinase, PI3K, AKT, mTOR Pathway
