- چکیده:
- چکیده انگلیسی: Background: Human T cell lymphotropic virus type I (HTLV-I)-associated myelopa-thy/tropical spastic paraparesis (HAM/TSP) is an inflammatory disease which occurs in less than 2% of HTLV-I -infected individuals. High proviral load, high HTLV-I-specific CD8+ cytotoxic T lymphocyte frequency (CTL) and host genetic factors such as HLA all appear to be associated with HTLV-I infection. Previous studies have shown that HLA-DRB1*01 increases the risk of HAM/TSP in Japanese HTLV-I infected individu-als.
Objective: To investigate the association between HLA class II DRB1 alleles and HLA class I alleles (HLA-Cw*08, B54, A*02 and A-30) in HTLV-I infected individu-als in Mashhad.
Methods: Here we determined the frequency of HLA class II DRB1, using INNO-LIPA reverse hybridization line probe assay, and HLA class I alleles (HLA-Cw*08,B54, A*02 and A-30) by PCR-SSCP method in healthy controls, HAM/TSP patients and HTLV-I infected individuals born and resident in Mashhad.
Results: The frequency of HLA-DRB1*01 alleles in this population was different from other areas of Iran. The frequency of HLA-DRB1*01 was significantly increased in HAM/TSP patients compared with carriers (p 0.028; OR=9.4). The frequency of HLA-Cw*08 was also significantly increased in HAM/TSP patients compared with controls (p=0.03; OR=13.5).
Conclusion: Our results may suggest that possession of HLA-DRB1*01 increases the risk of HAM/TSP in HTLV-I-infected individuals and HLA-Cw*08 correlates with low CTL immune response in HAM/TSP patients.- انتشار مقاله: 17-05-1395

- چکیده:
- چکیده انگلیسی: Background: Selenium (Se) is part of the glutathione peroxidase enzyme complex (GSH-PX) that plays an important role in antioxidant mechanisms in body, also it has been demonstrated that populations with low Se intake have 2-3 times greater risk of ischemic heart disease.
Objective: To determine the circulating levels of IL- 6, TNF-α, Cu, Zn, and Se in patients with chronic coronary artery disease (CCAD), acute myocardial infarction (AMI), and normal individuals.
Methods: Patients were divided into two groups: 25 subjects with CCAD and 25 patients with AMI. The control group included 50 normal individuals who did not have any history of ischemic heart disease, and were sex and age matched with the patients. Blood samples were collected during the first hours after the onset of chest pain in AMI group. Serum concentration of Se, Cu, and Zn were determined by atomic absorption spectrometry and TNF-α and IL-6 levels were measured using ELISA method.
Results: In both groups of patients there was a significant reduction in serum Se levels (82.36 + 11.31 mg/L in CCAD, 74.08+11.31mg/L in AMI, and 105+32.52mg/L in the control group, P=0.03). TNF-α titers were increased in AMI patients compared with CCAD and control group. Mean TNF-α levels were 37.44 pg/ml in CCAD, 914.32 pg/ml in AMI, and 4.80 pg/ml in the control group (P=0.01). Serum levels of IL-6 in CCAD and AMI patients were 3.28 ±15.55 pg/ml and 472±207.88 pg/ml, respectively, and 1.28 pg/ml in the control group (P=0.001).
Conclusion: These findings confirm previous studies and demonstrate that patients suffering from AMI exhibit lower plasma concentrations of Se and higher concentrations of pro-inflammatory cytokines of TNF-α and IL-6.- انتشار مقاله: 16-05-1395

- چکیده انگلیسی: Objective(s): Coronary artery disease (CAD) is known as a life threatening disease, worldwide. In this study the role of HTLV-1 infection was evaluated on cardiac involvement in an endemic region of northeastern Iran.
Materials and Methods: Serologic and molecular tests for HTLV-1 infection were carried out in subjects who had coronary angiography. A real-time PCR, TaqMan method, to quantify HTLV-1 proviral load (PVL), and routine hematological and biochemical tests were performed for study subjects.
Results: Twenty nine patients were HTLV-1+CAD+ and 13 cases were HTLV-1+CAD-. Although, there were no significant differences for risk factors like FBS, HDL, triglyceride, systolic and diastolic blood pressure (Cbp, Dbp), waist circumference (WC), hip circumference (WL), cholesterol (P=0.003), and LDL (P=0.007) levels, and monocyte count (P=0.05) had meaningful differences. The mean HTLV-1 PVL in HTLV-1+CAD+ subjects was 992.62±120 which was higher compared with HTLV-1+CAD- group (406.54±302 copies/104 PBMCs). Moreover, HTLV-1 PVL in males (833±108) was lower compared with females (1218±141 copies/104 PBMCs) (P=0.05). Patients with HTLV-1-PVL of more than 500 copies/104 had more diffused atherosclerosis plaque than patients with less than 500 (OR=6.87, 95% CI=1.34-35.05; P=0.016). Furthermore, patients with diffused coronary atherosclerosis had significantly higher levels of HTLV-1 PVL than patients with middle, proximal, and normal location of coronary sclerotic lesions (P<0.05).
Conclusion: Taken together, in endemic area, HTLV-1 infection, more likely is a facilitating factor for heart complications and the high HTLV-1 PVL might affect CAD manifestations.- انتشار مقاله: 27-08-1397

- چکیده:
- چکیده انگلیسی: Objective(s): Allergic rhinitis (AR) is a common hypersensitivity disease worldwide. Immunotherapy has been performed as the best treatment for years. This study aimed to study the gene expression pattern of immune system cells following an accelerated rush immunotherapy protocol (ARIT) in patients with AR.
Materials and Methods: Fifteen patients with AR (15–55 years old) resident in Mashhad, Iran, with positive prick test to regional aeroallergens (weed mix, grass mix, tree mix, and Salsola) enrolled in this study. All patients were treated for three months with 3-day ARIT protocol between July 2015 and August 2016. Clinical symptoms and quality of life were recorded by two questioners. The expression levels of FOXP3, TGF-β, IL-10, IL-17, IL-4, and IFN-γ genes in patient’s peripheral blood mononuclear cells were evaluated by SYBR Green real-time RT-PCR technique.
Results: The severity of disease and quality of life showed significant improvement following ARIT (P-value<0.05). Gene expression of IFN-γ and IL-10 was increased whereas TGF-β and IL-4 down-regulated, following ARIT, but these changes were not significant. However, gene expression of FOXP3 and IL-17 was significantly increased after intervention when compared with the baseline (P-value< 0.002).
Conclusion: Significant up-regulation of FOXP3 and IL-17 genes, additionally, a significant improvement in the clinical signs following ARIT might be related to increases in HLA-DR- and FOXP3+ Treg population at the initiation phase of ARIT. Employing the flow cytometry technique to study the phenotype of these cells is suggested for future studies.- انتشار مقاله: 05-04-1397

- چکیده:
- چکیده انگلیسی: Objective(s): Asthma results from the interaction between genetic and environmental factors. ADAM33 gene on chromosome 20p13 is associated with asthma and airway hyperresponsiveness. Materials and Methods: This is a case-control study, where four SNPs S1 (rs3918396), T1 (rs2280091), T2 (rs2280090), V4 (rs2787094) of ADAM33 gene have been assessed in patients with allergic asthma and normal controls (95 patients and 86 normal). Blood samples of these participants have been genotyped by PCR and the RFLP method. Results: There was no association between asthmatic patients and polymorphisms of alleles, genotypes and haplotypes of the ADAM33 gene. When categorizing the asthmatic patients in severe, moderate and mild groups, associations in the subcategories of asthmatic patients were found. There were associations between polymorphisms of C allele of T1 SNP with severe asthmatic patients and G allele of V4 SNP with moderate asthmatics respectively (P=0.006, P=0.01). There was a significant association between sensitivity to mite and polymorphism of C allele of T1 SNP (P=0.02). Besides, there was a significant association between sensitivity to weeds and genotype GG of V4 SNP (P=0.05). Conclusion: Polymorphisms of ADAM33 gene might be associated with severe asthma and sensitivity to aeroallergens in northeast of Iran, but further studies are needed to determine the polymorphisms in this area and other regions of our country.

- چکیده:
- چکیده انگلیسی: Primary immunodeficiency (PID) is a group of more than 400 distinct genetic disorders affecting both children and adults. As signs and symptoms of PID are usually heterogeneous and unspecific, based on the available human resources and laboratory facilities, diagnosis and follow-up of these patients can be challenging. In line with this notion, management and treatment of PID are practiced divergently in different PID centers. In order to reach a distinct national protocol and given the little evidence on appropriate or universal guidelines to improve the current status of management of the disease, the Iranian PID network designed a consensus suitable for regional resources. This review summarizes this PID guideline based on the importance of different clinical complications and the level of medical authority visiting those at the first line. Further, for each complication, appropriate interventions are mentioned to improve the approach.
