Qatar Medical Journal - 2 - Second Qatar Allergy Conference, April 2023

Background: The prevalence of asthma is 9% among adults in Qatar, and its severity can be attributed to intrinsic and extrinsic factors such as environmental changes. As part of the project to investigate the association between air pollution and asthma severity, the rate of exacerbations in adult patients with asthma has been studied in Qatar. Methods: Retrospective data of patients with asthma (16-70 Read More

Objective: Common variable immunodeficiency (CVID) is a complex inborn error of humoral immunity with complications of both infectious and non-infectious origins. Classifications of CVID patients provide a clearer understanding of the pathogenesis, prediction, and management of non-infectious complications. This study aims to classify Moroccan CVID patients based on the European classification (EUROclas Read More

Background and Aim: Chronic giardia infection can lead to non-erosive gastrointestinal disorders, including protein-losing enteropathy (PLE). This report describes non-diarrheal PLE in chronic giardiasis in children with defective humoral immunity. Methods: The retrospective report is related to 2 children known to have a monogenic inborn error of immunity. The first patient is a 13-year-old boy with X-linked agam Read More

The constant progress of genomics and the establishment of new functional tests have paved the way for identifying monogenic defects conferring a selective predisposition to infections by certain microbes as a new type of inborn errors of immunity (IEIs). Mendelian susceptibility to mycobacterial diseases (MSMD) is the most characterized of these IEIs, with 36 different disorders found in 20 disti Read More

Introduction Vocal cord dysfunction (VCD) can result from several psychological conditions such as stress, anxiety, and posttraumatic stress disorder; however, chronic gastroesophageal reflux disease (GERD) can cause it. The Clinical picture can mimic severe asthma and limit the patient’s quality of life. Treatment of vocal cord dysfunction can lead to complete resolution of the symptoms. Case Presentation A Read More

ABSTRACT Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic liver disease. If this disease is not treated, it might lead to fibrosis, cirrhosis, and its associated complications.1 Early recognition of this entity and immediate institution of therapy are the primary prognostic modifiers.2 Anti-nuclear autoantibodies can be used for diagnosis, particularly the anti-gp 210 and anti-Sp100 antibodies Read More

Introduction: Anti-centromere antibodies (ACAs) are a variety of anti-nuclear autoantibodies (ANA) directed against different kinetochore proteins. They are sought on HEp2 substrates by indirect immunofluorescence technique (IFI), where they appear in the form of about forty fine nuclear punctuations attached to the chromosomes during their different cell cycle phases. They are encountered in several a Read More

Introduction: Soluble anti-antigen antibodies (Anti-ENA) represent a specificity of anti-nuclear autoantibodies (ANA), which are directed against nuclear particles composed of small RNA (Ribonucleic acid) and proteins. They are found during certain autoimmune diseases (ADs), most frequently during systemic lupus erythematosus (SLE) and Gougerot syndrome. The aim of this study is to retrospectively analyze t Read More

Background: Obstructive sleep apnea (OSA) affects 1% to 5% of all children, with the most significant prevalence between ages 2 and 8. Correlations between OSA and Adenoid hypertrophy (AH) have been well-demonstrated in children. If untreated, OSA can cause growth impairment, neuro-cognitive and behavioral problems, and cardiovascular complications. Allergy was reported to be a vital risk fact Read More

Background: Every year, 14 million babies are born with low birth weight (LBW) and/or intrauterine growth restriction (IUGR) in developing countries. In Sudan, 15-25% of all newborns are born with LBW, with half being Term-LBW. The importance of nutrition in the first 1000 days of life has been well demonstrated. Evidence links IUGR to various health and developmental disorders, and intrauterine programmin Read More

Introduction: The periodic fever syndrome Familial Mediterranean Fever (FMF) is caused by mutations in MEFV, which promote inflammation and present with uncontrolled systemic and organ-specific inflammation that can resemble infectious conditions. It is diagnosed based on clinical criteria, including frequent symptoms such as abdominal and thoracic pain, family history, and response to treatment with c Read More
