Aspirin-Exacerbated Respiratory Disease Polymorphisms; a review study.

Aspirin exacerbated respiratory disease (AERD) is a condition caused by increased bronchoconstriction in people with asthma after taking aspirin or another NSAID. Molecular analysis of the human genome has opened up new perspectives on human polymorphisms and disease. This study was conducted to identify the genetic factors that influence this disease due to its unknown genetic factors.

Epidemiology, Sociodemographic Factors and Comorbidity for Allergic Rhinitis, Asthma, and Rhinosinusitis Among 15 to 65-year-Old Iranian Patients.

Fourth Update on the Iranian National Registry of Primary Immunodeficiencies: Integration of Molecular Diagnosis.

Background: The number of inherited diseases and the spectrum of clinical manifestations of primary immunodeficiency disorders (PIDs) are ever-expanding. Molecular diagnosis using genomic approaches should be performed for all PID patients since it provides a resource to improve the management and to estimate the prognosis of patients with these rare immune disorders.

Method: The current update of Iranian PID registry (IPIDR) contains the clinical phenotype of newly registered patients during last 5 years (2013-2018) and the result of molecular diagnosis in patients enrolled for targeted and next-generation sequencing.

Comparison of Common Monogenic Defects in a Large Predominantly Antibody Deficiency Cohort.

Background: Predominantly antibody deficiencies (PADs) are the most common primary immunodeficiencies, characterized by hypogammaglobulinemia and inability to generate effective antibody responses.

Objective: We intended to report most common monogenic PADs and to investigate how patients with PAD who were primarily diagnosed as suffering from agammaglobulinemia, hyper-IgM (HIgM) syndrome, and common variable immunodeficiency (CVID) have different clinical and immunological findings.

Methods: Stepwise next-generation sequencing and Sanger sequencing were performed for confirmation of the mutations in the patients clinically diagnosed as suffering from agammaglobulinemia, HIgM syndrome, and CVID.

Effect of childhood BMI on asthma: a systematic review and meta-analysis of case-control studies.

Background: Asthma is a multifactorial syndrome that threatens the health of children. Body mass index (BMI) might be one of the potential factors but the evidence is controversial. The aim of this study is to perform a comprehensive meta-analysis to investigate the association between asthma and BMI.

Determination of the Most Common Indoor and Outdoor Allergens in 602 Patients with Allergic Symptoms Using Specific IgE Local Panel.

Aeroallergens play an important role in developing allergic diseases. The aim of this study was to determine the outdoor and indoor sensitization using a specific regional panel of aeroallergens in allergic patients. All patients with allergic symptoms referred to Immunology, Asthma and Allergy Research Institute (IAARI) in Tehran, Iran from December 2010 to July 2013 entered this cross sectional study.

Cromolyn Sodium Attenuates Paraquat-Induced Lung Injury by Modulation of Proinflammatory Cytokines.

The current study aimed to investigate the effects of Cromolyn Sodium (CS) on proinflammatory cytokines in Paraquat (PQ)-induced lung damage in rat. Animals were randomly divided into 5 groups. Group 1 and 2 received nebulized vehicle and CS (8 mg/kg) for 3 consecutive weeks, respectively.

Impact of IgE-mediated Food Allergy on Parental Quality of Life in Iranian Patients.

Food allergy is a common disorder especially in the first years of life. Strict avoidance of the responsible food is the most effective therapeutic measure so far. But this continuous vigilance could be stressful for the patient and family and decreases their quality of life (QOL).

Evaluation of antibody response to polysaccharide vaccine and switched memory B cells in pediatric patients with inflammatory bowel disease.

Background/aims: Inflammatory bowel disease (IBD) is a chronic disease of the gastrointestinal tract, whose etiologies are still unknown. This study was performed to evaluate the humoral immune response in terms of B cell functions in selected IBD patients.

TNF-alpha single nucleotide polymorphisms in atopic dermatitis.

Tumor necrosis factor-alpha (TNF-α) could be considered as potential biomarkers in atopic dermatitis (AD), while its level could be influenced by cytokine single gene polymorphisms (SNP). This study was performed in 89 pediatric patients with AD and 137 controls to assess polymorphisms of the TNF-α gene at positions -308 and -238, using the polymerase chain reaction and the sequence-specific primers method. The highest positive allelic association that made the patients susceptible to AD was seen for TNF-α -238/G (p<0.

Association of single nucleotide polymorphisms of interleukin-1 family with atopic dermatitis.

Background: Interleukin-1 (IL-1) seems to have an important role in early reactions towards microbes, while its genetic variability could affect this role in atopic patients who have a distressed immunity towards dermatological infections.
