Intermittent airflow limitation, bronchial hyperresponsiveness (BHR), airway inflammation and remodelling are key pathophysiological components of bronchial asthma [1]. BHR, an abnormal increase in airflow limitation following exposure to a stimulus, is present in almost all patients with clinically current asthma. Furthermore, patients with more severe asthma have more responsive airways than ...
Asthma is characterized by inflammation of the airways that includes eosinophils, basal membrane thickening, epithelial sloughing, vascular changes, smooth muscle hypertrophy and hyperplasia, and mucous gland hyperplasia. Recently, there have been studies on the role of hypersensitivity and inflammation in asthma, but the role of bronchial smooth muscle remains unclear. Bronchial thermoplasty i...
Asthma in children up to 5 years of age is a disease that diagnosed on the basis clinical symptoms bronchial obstruction, such as: wheezing, cough and shortness breath variable intensity duration, clinically proven reversibility obstruction improvement after chronic use inhaled glucocorticosteroids lack grounds for suspecting causes other than asthma. Treatment childhood asthma graded therapy w...
BACKGROUND Bronchial epithelial ciliary dysfunction is an important feature of asthma. We sought to determine the role in asthma of neutrophilic inflammation and nicotinamide adenine dinucleotide phosphate (NADPH) oxidases in ciliary dysfunction. METHODS Bronchial epithelial ciliary function was assessed by using video microscopy in fresh ex vivo epithelial strips from patients with asthma st...
RATIONALE AND OBJECTIVES The authors performed this study to determine if bronchial wall thickening is present in children with moderate to severe asthma during periods free from clinical bronchoconstriction. MATERIALS AND METHODS The authors obtained low (radiation) dose thin-section computed tomographic (CT) scans in each of 18 control subjects and 21 children with moderately severe but sta...
Background The concept of Atopic march was developed to study the progress of Atopic Dermatitis to Allergic Rhinitis to Asthma. Epidemiologic studies have constantly demonstrated strong associations between Rhinitis and Asthma. Bronchial hyper-reactivity is an important component in the definition of Asthma. Many patients with Allergic Rhinitis have lower Airway hyperreactivity or bronchial hyp...
INTRODUCTION Bronchial Asthma is one of the most extensively studied respiratory diseases and its genetic basis is well established. Dermatoglyphic traits are formed under genetic control early in development but may be affected by environmental factors during first trimester of pregnancy. These patterns may represent the genetic makeup of an individual and therefore his/her predisposition to c...
Several studies on the prognosis of occupational asthma have shown that a significant proportion of patients continue to experience asthmatic symptoms and nonspecific bronchial hyperresponsiveness after cessation of work. The determinants of this unfavourable prognosis of asthma are: long duration of exposure before the onset of asthma; long duration of symptoms before diagnosis; baseline airwa...
