Immunogenic Potential of the Mediterranean Fever Gene in Patients with Coronavirus Disease: A Cross-Sectional Study.

Background: In December 2019, an outbreak of pneumonia caused by the novel coronavirus disease 2019 (COVID-19) became a pandemic and caused a global health crisis. This study evaluates the immunogenic potential of the Mediterranean fever () gene in patients with COVID-19.

Methods: A cross-sectional study was conducted from March to April 2020 in various COVID-19 referral centers in Ardabil, Iran.

The Effect of Aspirin on Moderate to Severe Asthmatic Patients with Aspirin Hypersensitivity, Chronic Rhinosinusitis, and Nasal Polyposis.

Asthmatic patients may have aspirin-exacerbated respiratory disease and experience acute dyspnea and nasal symptoms within 3 hours after the ingestion of aspirin. This study aimed to evaluate the effect and outcome of daily low-dose aspirin in the treatment of moderate to severe asthma in patients with concomitant aspirin hypersensitivity and chronic rhinosinusitis with nasal polyposis (CRSwNP). This clinical trial was conducted from February 2014 to February 2015 on 46 adult patients with moderate to severe asthma accompanied by CRSwNP.

Aspirin Sensitivity in Patients with Moderate to Severe Asthma.

Asthma induced by ingestion of aspirin occurs when symptoms arise within 30 minutes to three hours after aspirin consumption. Previous data indicate that sensitivity to aspirin may be associated with poorly controlled asthma. This study aims to evaluate the frequency of aspirin sensitivity in patients with moderate to severe asthma receiving conventional asthma therapy.

Characteristics, Etiology and Treatment of Pediatric and Adult Anaphylaxis in Iran.

Despite the increasing prevalence of anaphylaxis, there is little information about the characteristics and practice of healthcare providers in treating anaphylaxis, so this study was conducted to record the characteristics and therapeutic approaches of anaphylaxis from May 2012 until April 2015, the data of all patients diagnosed with anaphylaxis in the Allergy department of three referral university hospitals in Tehran, Iran were recorded. Thereafter, the demographics, clinical features, triggers and therapeutic approach were evaluated. This study investigated 136 individuals, 64 males (47%) between 6 months and 68 years old, as well as 72 others (52.

Evaluation of a new protocol for wheat desensitization in patients with wheat-induced anaphylaxis.

Aim: New approaches such as oral immunotherapy (OIT) may be useful in IgE-mediated anaphylaxis to wheat.

Patients & Methods: 12 patients underwent OIT protocol that comprised of two phases: the first with semolina flour and the second with spaghetti. Total and specific wheat IgE were assayed by ELISA before and after OIT and 18 months later.

A gain-of-function mutation of STAT1: A novel genetic factor contributing to chronic mucocutaneous candidiasis.

Heterozygous gain-of-function (GOF) mutations in the signal transducer and activator of transcription 1 (STAT1) have increasingly been identified as a genetic cause of autosomal-dominant (AD) chronic mucocutaneous candidiasis (CMC). In this article, we describe a 33-year-old man who experienced chronic refractory candidiasis, recurrent otitis media, and pneumonia resulting in bronchiectasis, severe oral and esophageal candidiases with strictures associated with hypothyroidism and immune hemolytic anemia. His son also suffered from persistent candidiasis, chronic diarrhea, poor weight gain, and pneumonia that resulted in his demise because of sepsis.

LPS-Responsive Beige-Like Anchor Gene Mutation Associated With Possible Bronchiolitis Obliterans Organizing Pneumonia Associated With Hypogammaglobulinemia and Normal IgM Phenotype and Low Number of B Cells.

LPS-Responsive Beige-like Anchor (LRBA) deficiency is a disease which has recently been described in a group of patients with common variable immunodeficiency (CVID) in association with autoimmunity and/or inflammatory bowel disease (IBD)-like phenotype. We here describe a 10-year-old boy who experienced recurrent infections, mainly in the respiratory system, associated with thrombocytopenia and anemia. Immunological workup showed low numbers of B cells and low IgG, but normal IgM levels.

The effects of vitamin D supplementation on airway functions in mild to moderate persistent asthma.

Background: Vitamin D is hypothesized to have some roles in innate and adaptive immunity, inflammation reduction, and remodeling; therefore, it is supposed to affect the asthma phenotype, severity, and response to inhaled corticosteroid (ICS).

Objective: To explore the synergistic effects of vitamin D supplementation in addition to asthma controllers (ICS or ICS plus long-acting β-agonist) on airway functions.

Methods: A randomized clinical trial was conducted in 130 individuals aged 10 to 50 years who lived in Tehran during a 24-week period.
