Insights

Wheezing infants in Saudi Arabia often have low vitamin A levels. Lower serum retinol concentrations correlate with more severe and persistent wheezing, indicating vitamin A status is linked to wheeze severity.

Area of Science:

  • Pediatric Pulmonology
  • Nutritional Biochemistry
  • Public Health

Background:

  • Wheezing is a common respiratory symptom in infants and young children.
  • Vitamin A deficiency can impact immune function and respiratory health.
  • Understanding vitamin A status in wheezing children is crucial for effective management.

Purpose of the Study:

  • To determine serum retinol levels in Saudi children experiencing wheezing.
  • To assess the relationship between serum retinol and the severity and course of wheezing.

Main Methods:

  • A prospective cohort study involved 400 Saudi children aged 3-36 months with wheezing.
  • Children were categorized into persistent (93) and acute (307) wheeze groups.
  • Wheeze severity was graded as mild, moderate, or severe.

Main Results:

  • Higher prevalence of deficient and marginal vitamin A was observed in persistent wheezing patients (9.7% deficient, 20.4% marginal) compared to acute wheezing patients (1.6% deficient, 8.1% marginal).
  • A significant association (p<0.05) was found between lower vitamin A concentrations and persistent wheezing.
  • Vitamin A deficiency was exclusively identified in children with severe wheezing.

Conclusions:

  • Prevalent vitamin A deficiency and marginal deficiency exist among wheezing infants in Saudi Arabia.
  • Serum vitamin A levels are significantly related to both the severity and the course of wheezing in children.

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
