INTRODUCTION: Procalcitonin (PCT) and C-reactive protein (CRP) are known inflammatory markers of severe infection; however, their ability to differentiate between infections of different origins is not clear yet. In this study, we evaluated PCT and CRP as markers of infection in hematopoietic stem cell transplantation (HSCT) patients. METHODS: Blood samples were collected to determine serum concentrations of PCT, CRP, d-Dimer, and to perform blood culture analysis...

The study investigated serum 25-Hydroxy vitamin D (25-(OH)D) deficiency and its prognostic values of patients newly diagnosed Hodgkin lymphoma (HL). With seventy-seven patients enrolled, the median level of 25-(OH)D was 44.5 nmol/L (range, 15.5-100.9 nmol/L) and 16 (20.8 %) of them were considered as 25-(OH)D deficiency. With a median follow-up of 28 months (range, 4-56 months), the 2-year progression-free survival (PFS) and overall survival (OS) rate were 75.3 %±5.5 % and 94.7 %±3.0 %, respectively. Patients with deficient 25-(OH)D level had inferior PFS (P<0...

A novel series of enantiopure naphthalimide-cycloalkanediamine conjugates were designed, synthetized and evaluated for in vitro cytotoxicity against human colon adenocarcinoma (LoVo), human lung adenocarcinoma (A549), human cervical carcinoma (Hela) and human promyelocytic leukemia cell lines (HL-60). The cytotoxicity of the compounds was highly dependent on size and relative stereochemistry of the cycloalkyl ring as well as length of the spacer. By contrast, any kind of enantioselection was observed for each pair of enantiomers...

BACKGROUND A rapid investigation of dengue viral infection is needed for physicians who manage patients with suspected dengue infection. The nonstructural protein 1 (NS1) test kit is commonly used to diagnose patients with acute febrile illness in dengue-endemic countries, although this test kit can yield false-positive results. The Dengue NS1 test kit mostly relies on cross-reaction among febrile illness patients with other viral infections rather than malignancies. CASE REPORT A 52-year-old male patient presented with 3 days of fever, intermittent gum bleeding, weight loss, and mucocutaneous bleeding...

BACKGROUND: There is a paucity of studies describing the incidence and risk factors for late-occurring (≥1 year) infectious complications in contemporary survivors of hematopoietic cell transplantation (HCT). METHODS: This was a retrospective cohort study of 641 1-year survivors of HCT, transplanted between 2010 and 2013 as adults, and in remission from their primary disease. Standardized definitions were used to characterize viral, fungal, and bacterial infections...

The Human T-Cell Lymphotropic Virus Type-1 (HTLV-1) is associated with severe pathologies as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), adult T-cell leukemia-lymphoma (ATLL) and infective dermatitis associated with the HTLV-1 (IDH). Interestingly, HTLV-1 infection does not necessarily imply in the development of pathological processes and it is unknown why some patients remains as asymptomatic carriers (AC). Despite some mutations in HTLV-1 genome appear to influence the outcome of HTLV-1, there are few studies that characterizes molecularly the hbz region...

The potential antitumor effects of jacalin, the plant lectin that specifically recognizes the tumor-associated Thomsen-Friedenreich antigen has been extensively studied. We had earlier reported jacalin to be mitogenic to K562, the Bcr-Abl expressing erythroleukemia cell line. The dearth of studies highlighting the proliferative effects of jacalin and other lectins motivated us to unveil the mechanism underlying the mitogenic effects of jacalin. Caveolin-1 (cav-1) is an integral membrane protein, known to play a crucial role in cell signaling, lipid transport, and membrane trafficking...

Interleukins are signaling molecules involved in the immune system, and they play a variety of roles in different diseases and cancers. Acute myeloid leukemia (AML) is the most common type of leukemia in adults, and survival rate after diagnosis is very low. Investigating the role interleukins play in AML can help understand the progression of the disease. There exists a need for more effective treatment of AML. Interleukins can be used to guide immunotherapy for AML. This review article will examine how specific interleukins play a role in AML disease progression and how they can be utilized as a future treatment option...

PURPOSE: Children with cancer are frequently hospitalized. However, hospitalization and death by disease category are not well defined < 5 years from diagnosis. METHODS: We conducted a retrospective cohort study using linked cancer registry-hospital discharge-vital records to identify cancer cases < 20 years at diagnosis during 1987-2012 (n = 4,567) and comparison children without cancer, matched on birth year and sex (n = 45,582). Data linkage identified serious morbidities resulting in cancer- and non-cancer-related hospitalizations or deaths < 5 years from diagnosis...

Giant molluscum contagiosum (MC) is a peculiar variant of the disease with the presence of multiple or single lesions larger than 5 mm. In contrast to typical molluscum contagiosum, dermoscopic features of giant lesions have been poorly described, and none of the reports included multiple giant lesions in an immunocompromised patient. We present a patient with acquired immunodeficiency syndrome diagnosed with multiple giant molluscum contagiosum along with the dermoscopic features of this entity. We examined a 40-year-old patient who had been diagnosed with acquired immunodeficiency syndrome (AIDS) two months earlier...

This paper reports a case of Trousseau syndrome with intracranial venous sinus thrombosis as the first manifestation, which is relatively rare in the clinic. A 44-year-old female patient presented with a blurred vision of the visual substance for 2 months, and the condition was aggravated with a headache for 10 days. The final diagnosis was intracranial venous sinus thrombosis and acute myeloid leukemia subtype M2. Anticoagulant + intra-arterial regimen (cytarabine + igdabistar) was given, and the patient's headache and blurred vision were gradually restored...

BACKGROUND: Leukemic stem cells (LSCs) of chronic myeloid leukemia (CML), persisting in the bone marrow (BM) niche, could be responsible for the relapses within the patients of whom the treatment-free remission (TFR) had been attempted. We assessed the presence of the CML LSCs in the peripheral blood (PB) and concurrently in the BM in the patients with chronic-phase CML (CP CML). PATIENTS AND METHODS: Thirty-eight patients with CP CML were included into the study...

OBJECTIVE: To detect fusion gene with pathological significance in a patient with refractory and relapsed acute B cell lymphoblastic leukemia (B-ALL) and to explore its laboratory and clinical characteristics. METHODS: Transcriptome sequencing was used to detect potential fusion transcripts. Other laboratory results and clinical data of the patient were also analyzed. RESULTS: The patient was found to harbor TCF3 exon 17-ZNF384 exon 7 in-frame fusion transcript...

Background and Purpose: Skin rashes, mostly seen in children and adolescents, are considered among the most common side effects of azole antifungals. Although therapeutic concentrations of voriconazole (VCZ) have been documented for infected skin, there is no evidence specifying whether specific dermatologic side effects could predict high VCZ serum concentration, especially in high-risk leukemic children. Case report: Herein, we report a unique skin side effect of VCZ in a 5-year-old boy with T-cell acute lymphoblastic leukemia (ALL) referred to Amir Medical Oncology Center in Shiraz, Iran...

Purpose: It is important that clinicians accurately predict the outcome of patients with sudden cardiac arrest (SCA). The complete blood count (CBC) is an easy and inexpensive test that provides information on blood content. Platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR), and delta neutrophil index (DNI) are relatively novel biomarkers that have been used in the prognosis of various diseases. We aimed to determine the usefulness of PLR, NLR, and DNI in predicting the outcomes of SCA...

Circular RNAs (circRNAs) are a class of novel non-coding RNAs (ncRNAs). Emerging evidence demonstrates that circRNAs play crucial roles in many biological processes by regulating linear RNA transcription, downstream gene expression and protein or peptide translation. Meanwhile, recent studies have suggested that circRNAs have the potential to be oncogenic or anti-oncogenic and play vital regulatory roles in the initiation and progression of tumors. Circular RNA Forkhead box O3 (circ-Foxo3, hsa_circ_0006404) is encoded by the human FOXO3 gene and is one of the most studied circular RNAs acting as a sponge for potential microRNAs (miRNAs) (Du et al...

Purpose: Diffuse large B-cell lymphoma (DLBCL) is the most common B-cell malignancy. Thirty to forty percent of DLBCL patients still experience relapse or develop refractory disease even with standard immunochemotherapy, leading to a poor prognosis. Currently, although several gene-based classification methods can be used to predict the prognosis of DLBCL, some patients are still unable to be classified. This study was performed to identify a novel prognostic biomarker for DLBCL. Patients and Methods: A total of 1850 B-cell non-Hodgkin lymphoma (B-NHL) patients in 8 independent datasets with microarray gene expression profiles were retrieved from the Gene Expression Omnibus (GEO) database and Lymphoma/Leukemia Molecular Profiling Project (LLMPP)...

Introduction: Acute myeloid leukemia (AML) is the most common type of acute leukemia in adults. HLA-DR and CD117 (c-Kit) are important diagnostic markers of AML. Our objective is to determine the prognostic significance of HLA-DR and CD117 expressions in newly diagnosed AML patients and determine the correlation between HLA-DR and CD117 expressions and other prognostic markers such as cytogenetic abnormalities, FLT3-ITD, response to treatment, and patient's survival. Methods: This study included 100 newly diagnosed AML patients...
