- - A study described four patients, including both typical and atypical SCID cases, who showed symptoms within six months of birth with various genetic mutations identified, such as in the RAG2, IL7R, ADA, JAK3, LIG4, and LAT genes.
- - The findings provide insights into the genetic diversity of SCID and emphasize the importance of early diagnosis and management for affected individuals, including the confirmation of mutations through Sanger sequencing in both patients and their parents.
Article Synopsis
- This study analyzed 69 patients suspected of having Leukocyte Adhesion Deficiency-I (LAD-I) over a 15-year period to better classify the severity based on clinical, laboratory, and genetic findings.
- The majority of patients were diagnosed at a median age of 6 months, with a notable delayed diagnosis and high rates of severe cases, leading to a 44.9% mortality rate.
- Genetic testing revealed several mutations associated with the disease, highlighting the importance of early detection and awareness among physicians to improve patient outcomes and support families with a history of LAD-I.
Article Synopsis
- Oral immunotherapy (OIT) is a new method for treating food allergies, specifically designed to help patients with wheat allergies develop tolerance.
- A study conducted from 2015 to 2017 involved 26 patients with confirmed wheat allergies, where they underwent OIT treatment and had their specific IgE levels and regulatory T cells monitored.
- Results indicated a high success rate of 100% for desensitization and 93.3% for tolerance, along with a significant drop in specific IgE levels after 12 months, suggesting OIT is an effective approach for wheat allergy management.

Article Synopsis
- Filaggrin is a crucial protein for skin protection, and mutations in its gene are linked to atopic dermatitis (AD), affecting about 50% of affected individuals.
- The study involved comparing 25 Iranian children with AD to 25 healthy controls, analyzing demographic data and specific genetic variations (polymorphisms) related to filaggrin.
- Results showed that certain polymorphisms were associated with the age and early onset of AD, but no significant links were found regarding disease severity or other allergy-related factors; further research is needed for broader insights.
Background: The inborn errors of immunity (IEIs) are a group of heterogeneous disorders mainly characterized by severe and recurrent infections besides other complications including autoimmune and inflammatory diseases. In this study, we aim to evaluate clinical, immunologic, and molecular data of monogenic IEI patients with and without autoimmune manifestations.
Methods: We have retrospectively screened cases of monogenic IEI in the Iranian PID registry for the occurrence of autoimmunity and immune dysregulation.
Serum sickness-like reactions in Iranian children: a registry-based study in a referral center.

July 2021
Introduction And Objectives: Considering that no studies have been done on a comprehensive review of Serum sickness-like reactions patients (SSLRs) at a referral center in Iran so far, this study aimed to determine the clinical and laboratory characteristics of children with SSRL in Tehran Children's Medical Center.
Patients: The present study was a registry-based study in which the data of 94 SSLRs patients registered in a two-year period were investigated. Confirmation of fever, rash, urticaria, arthralgia / arthritis and history of antibiotic consumption up to three weeks before were the criteria for the diagnosis.
Background: Common variable immunodeficiency (CVID) is the most frequent primary immunodeficiency disorder mainly characterized by recurrent bacterial infections besides other immunological defects including loss of or dysfunction of B cells and decreased immunoglobulin levels. In this study, our aim is to evaluate clinical, immunological, and molecular data of patients with a primary clinical diagnosis of CVID and autoimmune phenotype with a confirmed genetic diagnosis.
Methods: Among 297 patients with CVID, who were registered in the Iranian Primary Immunodeficiency Registry at Children's Medical Center Hospital in Iran, 83 patients have been genetically examined and 27 patients with autoimmunity and confirmed genetic mutations were selected for analysis.
Background: Congenital agammaglobulinemia is the first primary immunodeficiency disorder characterized by a defect in B lymphocyte development and subsequently decreased immunoglobulin levels. These patients are prone to suffer from recurrent infections mostly involving the respiratory tract. In this study, we aimed to describe in detail respiratory tract complications as the most prominent clinical feature among agammaglobulinemic patients.
