Abstract
BACKGROUND Inborn errors of immunity are a growing group of disorders with a wide spectrum of genotypic and phenotypic profiles. CARMIL2 (previously named RLTPR) deficiency is a recently described cause of immune dysregulation, mainly presenting with allergy, mucocutaneous infections, and inflammatory bowel disease. CARMIL2 deficiency is categorized under diseases of immune dysregulation with susceptibility to lymphoproliferative conditions. CASE PRESENTATION Here we describe a 29-years-old male from a consanguineous family, with food and sting allergy, allergic rhinitis, facial molluscum contagiosum (viral infection of the skin in the form of umbilicated papules), eosinophilia and highly elevated serum IgE level. Whole exome sequencing revealed numerous homozygous variants, including a CARMIL2 nonsense mutation, a gene regulating actin polymerization, and promoting cell protrusion formation. CONCLUSION The selective role of CARMIL2 in T cell activation and maturation through cyto-skeletal organization is proposed to be the cause of immune dysregulation in individuals with CARMIL2 deficiency. CARMIL2 has an important role in immune pathways regulation, through cell maturation and differentiation, giving rise to a balance between Th1, Th2, and Th17 immune response. This case can improve the understanding of the different impacts of CARMIL2 mutations on immune pathways and further guide the diagnosis of patients with similar phenotypes.

Abstract
BACKGROUND X-linked severe combined immunodeficiency is caused by IL2RG gene mutation. Several variations have been identified in the IL2RG gene, which potentially can prevent the production of nonfunctional proteins. Herein, a novel X-linked variant in the IL2RG gene is reported in twin brothers, associated with inflammatory bowel symptoms. CASE PRESENTATION The patients were 26-month-old monozygotic twin middle-eastern males with failure to thrive and several inpatient admissions due to severe chronic nonbloody diarrhea that started at the age of 12 months. Pancolitis was revealed after performing upper and lower gastrointestinal endoscopies on the twin with more severe gastrointestinal symptoms. Flow cytometric evaluation of the peripheral blood cells showed low levels of CD4+ cells in both patients. Next generation sequencing-based gene panel test results of the two patients proved a novel heterozygous missense X-linked IL2RG mutation (70330011 A > G, p.Trp197Arg) in one of the patients, which was predicted to be deleterious (CADD score of 28), which soon after was confirmed by Sanger segregation in his twin brother. Both parents were wild types and had never experienced similar symptoms. The patients received an human leukocyte antigen (HLA)-matched cord blood transplant. The twin with more severe gastrointestinal symptoms died 1 month after transplantation. In his brother, watery diarrhea eventually subsided after transplantation. CONCLUSION Intestinal involvement in X-linked severe combined immunodeficiency is a rare presentation that might be neglected. The increasing availability of genetic screening tests worldwide could be helpful for early detection of such lethal primary immunodeficiency diseases and in implementing effective interventions to handle the severe outcomes.

Abstract
OBJECTIVE Minimal residual disease (MRD) is considered the greatest prognostic factor in acute lymphoblastic leukemia (ALL). MRD is a valuable tool for anticipating impending relapse and treatment response assessment. The objective of the present study was to investigate whether the detection of IgH gene rearrangement using polymerase chain reaction (PCR)-based GeneScan analysis could be a complementary method to monitor MRD along with the quantitative realtime PCR (qPCR). MATERIALS AND METHODS In this cross-sectional study, we valued the MRD levels, based on the GeneScanning analysis (GSA), and then compared the data with quantitative real-time polymerase chain reaction at different time points in peripheral blood (PB) samples of adult B-lineage ALL patients (n=35). The specific polymerase chain reaction (PCR) primers for IGH gene FR-1 and fluorescence-labeled J-primer were used and analyzed by capillary gel electrophoresis on a sequencer. The results of this study were compared with the previously reported MRD results obtained by the IGH rearrangements allele-specific oligonucleotide (ASO) -qPCR methods. RESULTS The total concordance rate was 86.7%, with a P<0.001. MRD results obtained by GSA and ASO-qPCR methods were concordant in all diagnostic samples and samples on the 14th and 28th days of induction therapy. The results of these 2.5 years' follow-ups demonstrated a significant correlation between the two techniques (r=0.892, P<0.001). CONCLUSION It seems that the PCR-based GeneScan analysis of IGH gene rearrangement detection may be a valuable molecular technique to distinguish monoclonality from polyclonality. And also, it may be a precise tool to detect the residual leukemic DNA in the PB follow-up samples of patients.

Abstract
Background Primary ciliary dyskinesia (PCD), also known as the immotile-cilia syndrome, is a clinically and genetically heterogeneous syndrome. Improper function of the cilia causes impaired mucociliary clearance. Neonatal respiratory distress, rhinosinusitis, recurrent chest infections, wet cough, and otitis media are respiratory presentations of this disease. It could also manifest as infertility in males as well as laterality defects in both sexes, such as situs abnormalities (Kartagener syndrome). During the past decade, numerous pathogenic variants in 40 genes have been identified as the causatives of primary ciliary dyskinesia. DNAH11 (dynein axonemal heavy chain 11) is a gene that is responsible for the production of cilia's protein and encodes the outer dynein arm. Dynein heavy chains are motor proteins of the outer dynein arms and play an essential role in ciliary motility. Case Presentation. A 3-year-old boy, the offspring of consanguineous parents, was referred to the pediatric clinical immunology outpatient department with a history of recurrent respiratory tract infections and periodic fever. Furthermore, on medical examination, situs inversus was recognized. His lab results revealed elevated levels of erythrocyte sedimentation rate (ESR) and C reactive protein (CRP). Serum IgG, IgM, and IgA levels were normal, while IgE levels were elevated. Whole exome sequencing (WES) was performed for the patient. WES demonstrated a novel homozygous nonsense variant in DNAH11 (c.5247G > A; p. Trp1749Ter). Conclusion We reported a novel homozygous nonsense variant in DNAH11 in a 3-year-old boy with primary ciliary dyskinesia. Biallelic pathogenic variants in one of the many coding genes involved in the process of ciliogenesis lead to PCD.

Abstract
BACKGROUND Immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome is a rare autosomal recessive disorder. ICF1 is caused by bi-allelic mutations in the gene encoding deoxyribonucleic acid methyltransferase-3B (DNMT3B). Herein, we report a novel homozygous DNMT3B mutation in a patient with ICF1. CASE PRESENTATION An eight-month-old Iranian Caucasian infant of consanguineous 1st-degree cousins presented to our clinic for evaluation of neutropenia. Physical examination was unremarkable except for low-set ears and a systolic cardiac murmur. He had a history of recurrent respiratory infections and oral thrush. Moreover, a collateral artery between the bronchial and pulmonary arteries was observed on the angiogram, mimicking a patent ductus arteriosus on the echocardiogram. Growth percentiles were normal; however, he had a neurodevelopmental delay. Family history was significant for a sibling who deceased at nine months of age after recurrent respiratory infections. Laboratory evaluation revealed a normal white blood cell count with neutropenia and normal bone marrow studies. He had hypogammaglobinemia with normal flow cytometric studies and was treated with prophylactic trimethoprim-sulfamethoxazole and itraconazole. After that, he was re-admitted three times due to recurrent episodes of pneumonia and an episode of pseudomonas aeruginosa meningitis. Currently, he is five years old and doing well on monthly intravenous immunoglobulin. Due to recurrent infections, hypogammaglobulinemia, and neutropenia, as well as a family history of consanguinity and a sibling who deceased during infancy, a primary immune deficiency was suspected. Genetic studies utilizing whole-exome sequencing demonstrated a homozygous missense mutation in DNMT3B (LRG_56t1:c.2008C>T; p.Arg670Trp) in the patient studied. The mutation has not been previously reported. CONCLUSION We describe a novel homozygous DNMT3B mutation in an Iranian boy with ICF1. It is associated with recurrent infections, hypogammaglobinemia, neutropenia, mild facial anomalies, and a bronchopulmonary collateral artery.

Abstract
Common variable immunodeficiency (CVID) is the most prevalent form of symptomatic primary humoral immunodeficiencies characterized by failure in the final differentiation of B lymphocytes. The majority of CVID cases have no identified genetic defect, and epigenetic alteration could be involved in the pathogenesis of CVID. Hence, we aimed to evaluate the expression of hsa-miR-125b-5p -and, B lymphocyte-induced maturation protein-1(BLIMP-1) and interferon regulatory protein-4 (IRF-4) in a group of CVID patients with no definitive genetic diagnosis in comparison with healthy individuals. Ten CVID patients (all known genes excluded) and 10 age and sex-matched healthy controls participated in the study. B lymphocytes were isolated and expression of miR-125b-5p, IRF4, and BLIMP1 were evaluated by real-time polymerase chain reaction (RT-PCR). Moreover, B cell subsets were analyzed by flow cytometry. The results showed that the relative expression of miR-125b-5p in CVID patients was increased while it was decreased for the BLIMP1 and IRF4 transcription factors compared with the healthy controls. Although a reduction was observed in switched and non-switched memory B cells among all high-miR patients, these subsets were decreased in patients with normal miR expression (71.0% and 85.0%, respectively). Our results suggest that overexpression of miR-125b-5p affects the terminal differentiation of B cells in a selected group of CVID patients by downregulating the BLIMP-1 gene and more intensively for the IRF-4 gene expressions.

Abstract
BACKGROUND Severe congenital neutropenia (SCN4) caused by mutations in glucose-6-phosphatase catalytic subunit 3 (G6PC3) is characterized by recurrent infections due to severe neutropenia, and it may be accompanied by other extra-hematopoietic manifestations; including structural heart defects, urogenital abnormalities, prominent superficial venous markings, growth retention, and inflammatory bowel diseases with rare incidence. The homozygous or compound heterozygous mutations of G6PC3 are responsible for most cases of autosomal recessive SCN4. Herein, we present two cases of SCN4 affected by novel mutations in the G6PC3, in addition to a summarized list of variants in G6PC3 gene that are reported as pathogenic and related to the SCN4 phenotype. CASE PRESENTATION Herein we present two cases of SCN4; the first case was a three-months old boy with severe neutropenia and prior history of hospitalization due to umbilical separation, umbilical herniation, omphalitis, and pyelonephritis; and the second case was an eight-year-old with a history of neutropenia, recurrent and severe episodes of intractable diarrhea, refractory rectovaginal and rectoperineal fistula, congenital inguinal hernia, and ASD type 2. Whole exome sequencing was performed for both cases and revealed two novel homozygous missense mutations in G6PC3 that were predicted to be deleterious; c.337G>A, p. Gly113Arg in the first case and c.479C>T; P. Ser160Leu in the second case. To our knowledge, both of these two mutations has not been reported in the G6PDC3 gene. CONCLUSIONS In patients with severe neutropenia with varying extra hematopoietic syndrome, mutation of G6PC3 should be suspected after ruling out other mutations related to neutropenia. This study pointed toward novel G6PC3 mutations, that should be considered in order to diagnose patients with severe congenital neutropenia.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes novel coronavirus disease (COVID-19), is the seventh pathogenic coronavirus recently discovered in December 2019 in Wuhan, China. To date, our knowledge about its effect on the human host remains limited. It is well known that host genetic factors account for the individual differences in the susceptibility to infectious diseases. The genetic susceptibility factors to COVID-19 and its severity are associated with several unanswered questions. However, the experience gained from an earlier strain of coronavirus, SARS-CoV-1, which shows 78% genetic similarity to SARS-CoV-2 and uses the same receptor to bind to host cells, could provide some clues. It, therefore, seems possible to assemble new evidence in order to solve a potential genetic predisposition puzzle for COVID-19. In this chapter, the puzzle pieces, including virus entry receptors, immune response, and inflammation-related genes, as well as the probable genetic predisposition models to COVID-19, are discussed.

Abstract
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a multi-system disorder caused by several homozygous or compound heterozygous mutations, mostly in the nuclear gene of TYMP. Our current knowledge on the underlying pathology of the disease is derived through the study of about 200 cases of different ethnicities. Clinical presentations include severe cachexia, weakness, ptosis, diplopia, abdominal cramps or digestive tract disorders, hearing impairment, and paresthesia.Herein, we aim to present five novel mutations of the nuclear gene of TYMP in six Iranian patients diagnosed with MNGIE. In our population, age at the time of diagnosis was 18 to 49 years, while the onset of the symptoms varied from 13 to 20 years. We detected two pathogenic non-frameshift nonsense premature stop codon mutations (c.1013C > A, and c.130C > T), one variant of uncertain significance (VUS) non-frameshift missense mutation (c.345G > T), one likely pathogenic frameshift insertion (c.801_802insCGCG), and one likely benign homozygous non-frameshift deletion (c.1176_1187del) from two siblings. Our findings also confirm the autosomal recessive inheritance pattern of MNGIE in the Iranian population. The lack of knowledge in the area of nuclear gene-modifier genes shadows the genotype-phenotype relationships of MNGIE.

Abstract
BACKGROUND Dedicator of Cytokinesis 8 (DOCK8) deficiency, the most frequent cause of autosomal recessive hyper immunoglobulin (Ig)E syndrome, is a rare combined immunodeficiency. OBJECTIVE In this study, we report seven patients with consanguineous parents with five novel variants within the DOCK8 gene. METHODS For genetic analysis, we performed Whole Exome Sequencing (WES), or targeted sequencing by means of Next-generation sequencing (NGS) for some of the patients. For others, Sanger sequencing, Fluorescence-activated cell sorting (FACS), or polymerase chain reaction (PCR) was used. RESULTS We report five novel variants within the DOCK8 gene: three deletions (deletion of exons 4-12, 24-30, and 22-27), one frameshift (LRG_196:g.189315dup;p.(Leu1052Profs*7)), and a splice region variant (LRG_196t1:c.741+5G>T). Patients presented with skin lesions, food allergy, candidiasis, otitis, recurrent respiratory infections, short stature, aortic aneurism, gynecomastia, and coarse facial features. Patients had leukocytosis, eosinophilia, lymphopenia, and monocytosis, elevated IgE, IgG, IgA , reduced IgM and IgA levels. Patients had a low percentage of CD3+ and CD4+ cells, and a high percentage of CD19+, CD27+CD19+, and recent thymic emigrants T cells. The percentage of natural killer cells was increased in one of the patients while it was decreased in another patient. One patient died due to disseminated intravascular coagulation after hematopoietic stem cell transplantation. CONCLUSION We reported novel variants within the DOCK8 gene and highlighted risk of aneurysms in these patients, which have been rarely reported in these patients.

Abstract
Common variable immunodeficiency (CVID) is a primary immunodeficiency disease with a heterogeneous genetic background. Lipopolysaccharide-responsive beige-like anchor (LRBA), as well as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), have important regulatory roles in the immune responses. Here, we have investigated the expression of LRBA and CTLA-4 proteins in CVID patients with at least one presentation of early-onset occurrence, autoimmunity, or enteropathy. In this study, 20 newly diagnosed CVID patients without infection only phenotype, and ten healthy individuals were enrolled. The expressions of LRBA and CTLA-4 proteins were assessed by western blotting and flow cytometry, respectively. The patients were divided into two groups of autoimmunity-positive (11 cases) and autoimmunity-negative (9 patients). LRBA and CTLA-4 expressions were significantly lower in autoimmune-positive patients than in healthy individuals (P = .03 and P = .03, respectively). Autoimmune-negative patients had lower expression of LRBA and CTLA-4 than the control group, although it was not significant. There was a positive correlation between the expressions of LRBA and CTLA-4 in both groups of patients (P < .05). Furthermore, the highest frequency of LRBA (85.7%) and CTLA-4 (71.4%) defects was detected in those with concomitant presence of autoimmunity, enteropathy, and early-onset occurrence. Concurrent presence of autoimmunity, enteropathy, and early-onset occurrence in CVID patients could be indicative of a lack of expression in LRBA and CTLA-4 proteins. This could be helpful in early diagnosis and initiation of appropriate treatment in these patients prior to genetic confirmation.

Abstract
The WAVE regulatory complex (WRC) is crucial for assembly of the peripheral branched actin network constituting one of the main drivers of eukaryotic cell migration. Here, we uncover an essential role of the hematopoietic-specific WRC component HEM1 for immune cell development. Germline-encoded HEM1 deficiency underlies an inborn error of immunity with systemic autoimmunity, at cellular level marked by WRC destabilization, reduced filamentous actin, and failure to assemble lamellipodia. Hem1-/- mice display systemic autoimmunity, phenocopying the human disease. In the absence of Hem1, B cells become deprived of extracellular stimuli necessary to maintain the strength of B cell receptor signaling at a level permissive for survival of non-autoreactive B cells. This shifts the balance of B cell fate choices toward autoreactive B cells and thus autoimmunity.

Abstract
We describe a cohort of 25 Iranian patients with infantile inflammatory bowel disease (IBD), 14 (56%) of whom had monogenic defects. After proper screening, patients were referred for whole exome sequencing (WES). Four patients had missense mutations in the IL10 RA, and one had a large deletion in the IL10 RB. Four patients had mutations in genes implicated in host:microbiome homeostasis, including TTC7A deficiency, and two patients with novel mutations in the TTC37 and NOX1. We found a novel homozygous mutation in the SRP54 in a deceased patient and the heterozygous variant in his sibling with a milder phenotype. Three patients had combined immunodeficiency: one with ZAP-70 deficiency (T+B+NK-), and two with atypical SCID due to mutations in RAG1 and LIG4. One patient had a G6PC3 mutation without neutropenia. Eleven of the 14 patients with monogenic defects were results of consanguinity and only 4 of them were alive to this date.

Abstract
Objectives: Ataxia-telangiectasia (A-T) is an autosomal recessive neurodegenerative disorder with multisystem involvement caused by homozygous or compound heterozygous mutations in the ataxia telangiectasia mutated (ATM) gene which encodes a serine/threonine protein kinase. The aims of this study were to investigate class switch recombination (CSR) and to review the clinical and immunologic phenotypes of 3 groups of A-T patients, including A-T patients with CSR defects (CSR-D), A-T patients with selective immunoglobulin A deficiency (IgA-D) and A-T patients with normal Ig level. Methods: In this study, 41 patients with confirmed diagnosis of A-T (16 A-T patients with HIgM, 15 A-T patients with IgA-D, and 10 A-T patients with normal Ig levels) from Iranian immunodeficiency registry center were enrolled. B-cell proliferation, in vitro CSR toward IgE and IgA were compared between three groups as well as G2 radiosensitivity assay. Results: Earliest presentation of telangiectasia was a significant hallmark in A-T patients with CSR-D (p = .036). In this investigation, we found that the frequency of respiratory infection (p = .002), pneumonia (p = .02), otitis media (p = .008), chronic fever (p < .001), autoimmunity (p = .02) and hepatosplenomegaly (p = .03) in A-T patients with HIgM phenotype were significantly higher than the other groups. As expected IgE production stimulation and IgA CSR were perturbed in HIgM patients that were aligned with the higher readiosenstivity scores in this group. Conclusion: A-T patients with HIgM compared to other A-T patients presenting more infections and noninfectious complications, therefore, early detection and careful management of these patients is necessary.

Abstract
BACKGROUND Common variable immunodeficiency (CVID) is a heterogeneous group of disorders, characterized by recurrent upper and lower respiratory tract infections and some noninfectious clinical complications. OBJECTIVE To provide a detailed evaluation of respiratory presentations and complications in a cohort of Iranian patients with CVID. METHODS A retrospective cohort study was conducted on 245 CVID patients who were recorded in the Iranian primary immunodeficiency disorders registry network. Respiratory manifestations were evaluated by reviewing clinical hospital records, immunologic findings, pulmonary function tests (PFT), and high-resolution computed tomography (HRCT) scans. RESULTS Most of the patients (n = 208, 85.2%) had experienced at least 1 episode of acute respiratory manifestation, and pneumonia was observed in 31.6 % (n = 77) of cases as a first disease manifestation. During the follow-up, pneumonia, sinusitis, and otitis media were documented in 166 (68.6%), 125 (51.2%), and 103 (42.6%) cases, respectively. Abnormal PFT measurements were documented in 53.8% of patients. Among these patients, 21.5% showed restrictive changes, whereas 18.4% of patients showed an obstructive pattern. Bronchiectasis was the most frequent radiological finding, confirmed in 27.2% of patients. Patients with bronchiectasis were older at the time of immunodeficiency diagnosis (P < .001) and had longer diagnosis delay (P < .001) when compared with patients without bronchiectasis. CONCLUSION This study highlights the importance of monitoring the respiratory tract system even in asymptomatic patients. Pulmonary function tests and CT scans are the most commonly used techniques aiming to identify these patients early, aiming to reduce the rate of long-term respiratory complications.

Abstract
Objectives: Common variable immunodeficiency is a primary immunodeficiency disease characterized by hypogammaglobulinemia and heterogeneous clinical features. Neutropenia is a rare complication among CVID patients leading to a higher rate of infections and morbidity. Multiple factors (e.g. autoimmunity, infections, drugs and etc.) are found to underlie this complication.Methods: In the present study, demographic, clinical and laboratory data were compared between two groups of CVID patients with and without neutropenia.Results: Frequency of neutropenia was 8.1%. Infectious complications were the most prevalent clinical manifestations regardless of presence of neutropenia. However, candida infection and septicemia were significantly higher in neutropenic patients (p = 0.001 and p = 0.01, respectively). The most prominent clinical phenotypes of CVID patients with neutropenia were polyclonal lymphocytic infiltration and autoimmunity, both being considerably higher compared to the non-neutropenic group (p = 0.04 and p = 0.009, respectively). The mortality rate in neutropenic patients was higher than in patients without neutropenia (61.1 vs. 25.2%, p = 0.004).Conclusion: Although neutropenia is a rare complication among CVID patients, it is associated with frequent and severe clinical complications, including autoimmunity and lymphoproliferative conditions. Also, its accompaniment with higher mortality frequency in CVID patients indicates a need for more precise attention and consideration regarding specific treatment in neutropenic patients.

Abstract
Hyper Immunoglobulin M syndrome (HIGM) is a rare primary immunodeficiency disorder characterized by low or absent levels of serum IgG, IgA, IgE and normal or increased levels of serum IgM. Various X-linked and autosomal recessive/dominant mutations have been reported as the underlying cause of the disease. Based on the underlying genetic defect, the affected patients present a variety of clinical manifestations including pulmonary and gastrointestinal complications, autoimmune disorders, hematologic abnormalities, lymphoproliferation and malignancies which could be controlled by multiple relevant therapeutic approaches. Herein, the epidemiology, pathogenesis, clinical manifestations, diagnosis, management, prognosis and treatment in patients with HIGM syndrome have been reviewed.

Abstract
Introduction Treatment of metastatic castration-resistant prostate cancer with conventional therapies is still not successful. Therefore, application of novel biological approaches such as immunotherapy, which appears to be more effective and less toxic, is necessary. Monoclonal antibodies against cancer specific antigens are a kind of immunotherapy that have been approved for specific types of cancer and are being investigated for prostate cancer as well. The aim of this review was to assess the effectiveness and safety of monoclonal antibodies for treatment of advanced prostate cancer. Method According to the search strategy stated in our systematic review protocol, Scopus, Medline, TRIP, CENTRAL, ProQuest, DART and OpenGrey databases were searched. Data collection and quality assessment were done independently by two authors and any disagreements between the collected data were resolved by a third author. A meta-analysis was not feasible as there was a considerable statistical heterogeneity among the trials. Hence, this review was limited to a narrative analysis of the included studies. Results We found 9756 references by applying search strategy in 4 databases of journal articles and 3 databases of grey literature. We then discarded 3957 duplicate citations using Endnote software and 5143 articles due to obvious irrelevancy of their topics in primary screening. In secondary screening of 656 fulltexts, we excluded 538 articles, and finally included 12 trials in this systematic review, updated on 23 June 2017. The overall quality of the studies was fair. In general, results of this systematic review show promising advances in the treatment of prostate cancer patients with monoclonal antibodies against prostate-specific antigens with regard to PSA/disease response. Some of the studies reported pain relief after treatment as well. Conclusion Currently, the role of immunotherapy in the treatment of advanced prostate cancer still remains debated. Although passive specific immunotherapy could be offered as a novel therapeutic option in the coming years, patients should be informed about the risks and benefits of this therapy. One of the obstacles in this review was the lack of adequate assessment of survival-related endpoints reported in the included studies. Our study provides support for further research in this field.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) mostly comprised of Crohn's disease (CD) and ulcerative colitis (UC) is a condition arising from the combined effects of genetic, environmental, and immunological factors. IBD is associated with inflammation and altered cytokine profile. OBJECTIVE This study was aimed at assessing the association between T helper type 1 (Th1) cytokine polymorphisms (interferon gamma [IFN-γ] +874 A/T, interleukin-12 [IL-12] -1188 A/C, IL-2 -330 G/T, IL-2 +166 G/T) and susceptibility to and clinical features of IBD. METHODS The study population was composed of 75 IBD patients (40 CD patients and 35 UC patients) and 140 healthy controls. Genotyping was performed using polymerase chain reaction with sequence-specific primers. RESULTS The A allele of IFN-γ +874 polymorphism was overrepresented in the whole population of patients with IBD (OR 1.63; 95% CI 1.08-2.47; p = 0.020) and as well in the subpopulation of patients with CD (OR 2.14; 95% CI 1.26-3.63; p = 0.004), but not in UC. Multiple pairwise comparisons indicated that genotypes of single nucleotide polymorphisms (SNPs) within the IL-2 and IFN-γ genes are correlated with IBD, CD, and UC, while neither allele nor genotype frequency of th1 IL-12 -1188 polymorphism was associated with IBD, CD, or UC. Haplotype analysis also revealed that the presence of IL-2 -330/+166 TG haplotype versus the remaining haplotypes (GG, TT, and GT) is a protective factor against IBD (OR 0.62; p = 0.046). CONCLUSIONS The present study reports (for the first time) significant associations between SNPs within the IFN-γ and IL-2 genes and IBD.

Abstract
BACKGROUND Changes in cytokine expression have been frequently found in patients with inflammatory bowel disease (IBD). Cytokine values outside the normal range may be somewhat related to common polymorphisms within cytokine genes. OBJECTIVE The present study was designed to investigate the possible association between polymorphisms within Interleukin IL-4 and IL-10 genes and susceptibility to and clinical features of IBD. METHODS The study population was composed of 140 healthy controls and 75 patients with IBD (40 patients with Crohn's disease (CD) and 35 patients with ulcerative colitis (UC)). Genotyping was performed using polymerase chain reaction with sequence-specific primers. RESULTS Higher frequencies for the C allele of IL-4-590 polymorphism (P < 0.0001; odds ratio [OR], 5.68; 95% confidence interval [95% CI], 3.28-9.83) and for the T allele of IL-4-1098 polymorphism (P = 0.016; OR, 1.83; 95% CI, 1.11-3.02) were observed in the whole group of IBD patients. The IL-4-590 C allele was also significantly overrepresented when IBD patients were subdivided into CD and UC (P < 0.0001; OR, 5.2-6.28). While the IL-4-1098 T allele was present at higher frequencies in patients with UC (P = 0.05; OR, 1.95), but not in CD (P = 0.09). Multiple pairwise comparisons indicated that genotypes of all polymorphisms investigated within IL-4 gene are correlated with IBD, CD, and UC. Haplotype analysis showed that the IL-4-1098/-590 TC haplotype might predispose individuals to IBD, CD, and UC whereas the IL-4-1098/-590 TT and GC haplotypes have a protective effect. On the contrary, neither allele nor genotype frequencies of IL-10 polymorphisms (IL-10-1082 A > G, IL-10-592 A > C, and IL-10-819 T > C) were associated with IBD, CD, or UC. CONCLUSIONS The present study suggests that IL-4 polymorphisms might play a role in susceptibility to IBD and its major subtypes in the Iranian population.

Abstract
BACKGROUND Ulcerative colitis (UC) is inflammatory bowel disease (IBD), characterized by chronic inflammation episodes within mucosal layer of the intestine mostly affecting colon and rectum. As the role of innate immunity in pathogenesis of disease and important role of NLRP3, the aim of this study is to investigate the association of NLRP3 SNPs with UC in Iranian patients. METHODS Blood samples from 45 UC patients and 56 healthy subjects were tested for single nucleotide polymorphisms in rs10754558, rs3806265, rs4612666, and rs35829419 of NLRP3 gene, using real-time PCR method. RESULTS Among the investigated SNPs, "GG" genotype of rs10754558 have been 2.48 times more common among UC patients (P=0.04), while "CG" genotype has indicated protective effect against UC, as more frequently found in healthy subjects. CONCLUSION Despite no significant association between three investigated SNPs and disease, "GG" and "CG" genotypes of rs10754558 have been significantly associated with disease.

Abstract
MRD detection with allele-specific oligonucleotide-quantitative polymerase chain reaction (ASO-qPCR) and using clone-specific immunoglobulin/T cell receptor rearrangements is considered as a powerful prognostic factor in acute lymphoblastic leukemia (ALL). In the present study, we evaluated an ASO-qPCR assay for MRD quantification in peripheral blood (PB) samples of adult patients with ALL. DNA was isolated from PB samples of patients with newly diagnosed ALL. They were first investigated by multiplex-PCR assay to identify V/J usage. An ASO-qPCR technique was then applied for 2.5-year monthly MRD quantification for detection of patient-specific Ig/TCR receptor rearrangements as a molecular target. From 98 patients who were diagnosed as ALL, 72 (73.5%) were enrolled in the present study for MRD detection. MRD was successfully quantified in patients with 1-month interval time. MRD level at the end of induction therapy up to day 88 was the only significant prognostic factor. Regarding MRD level, patients were categorized into two groups of low and high-risk. 2.5-year OS in all three time points (days 28, 58 and 88) were significantly lower in high-risk group (P < 0.008). The results of the 2.5-year MRD detection indicate that MRD level at the end of induction up to about 6 months after the first diagnosis was associated with clinical outcome. This study may highlight the usefulness of PB and the definitions of cut-off level for early prediction of relapse and for stratifying ALL patients. Short-interval time points and frequent PB sampling to monitor MRD level is suggested for early clinical relapse prediction and clinical management of the disease.

Abstract
BACKGROUND The Hypermethylation of Ras association domain family (RASSF) often plays a key role in malignant progression of solid tumors; however, their impact on the prognosis and survival of adult ALL patients remain elusive. METHODS The frequency of the promoter methylation pattern of RASSF6 and RASSF10 were analyzed in the peripheral blood (PB) samples taken at the time of diagnosis of 45 ALL patients. The methylation-specific PCR (MSP) assay was used to detect the DNA methylation patterns. RESULTS RASSF6 was frequently hypermethylated in patients diagnosed with pre-B-ALL (90.9%) and B-ALL (87.5%), followed by T-ALL (66.7%); whereas, RASSF10 methylation was more confined to T-ALL (80%) as compared to B-ALL (25%) and pre-B ALL (9.1%) patients. Moreover, hypermethylation of RASSF6 was significantly associated with a poor prognosis and shorter overall survival (OS) in patients with pre-B-ALL (log-rank test; P=0.041). CONCLUSION RASSF6 and RASSF10 were frequently hypermethylated in the samples at the time of diagnosis of adult ALL patients. Our study represents the first report of methylation of RASSF6 at a high frequency in patients with pre-B ALL. Furthermore, hypermethylation of RASSF6 was significantly associated with inferior overall survival in pre-B ALL patients. It may suggest that the frequent epigenetic inactivation of RASSF6 plays an important role in the pathogenesis and progression of pre-B-ALL.

Abstract
In this work, the effects of different methods of activation on CO2 adsorption performance of activated carbon were studied. Activated carbons were prepared from biochar, obtained from fast pyrolysis of white wood, using three different activation methods of steam activation, CO2 activation and Potassium hydroxide (KOH) activation. CO2 adsorption behavior of the produced activated carbons was studied in a fixed-bed reactor set-up at atmospheric pressure, temperature range of 25-65°C and inlet CO2 concentration range of 10-30 mol% in He to determine the effects of the surface area, porosity and surface chemistry on adsorption capacity of the samples. Characterization of the micropore and mesopore texture was carried out using N2 and CO2 adsorption at 77 and 273 K, respectively. Central composite design was used to evaluate the combined effects of temperature and concentration of CO2 on the adsorption behavior of the adsorbents. The KOH activated carbon with a total micropore volume of 0.62 cm(3)/g and surface area of 1400 m(2)/g had the highest CO2 adsorption capacity of 1.8 mol/kg due to its microporous structure and high surface area under the optimized experimental conditions of 30 mol% CO2 and 25°C. The performance of the adsorbents in multi-cyclic adsorption process was also assessed and the adsorption capacity of KOH and CO2 activated carbons remained remarkably stable after 50 cycles with low temperature (160°C) regeneration.
