The relationship between Mycoplasma pneumoniae (MP) infection and asthma has rarely been explored through examination of airway reactivity. The aim of this study was to determine airway reactivity changes after MP infection in children. First, 106 children were divided into four groups according to the existence of MP infection and/or asthma. Then children with only MP belonged to the MP group;...

BACKGROUND Regular use of inhaled beta(2)-agonists has been associated with a paradoxical loss of asthma control and a deterioration of airway hyper-responsiveness, but the underlying mechanism is unknown. The neurotrophin brain-derived neurotrophic factor (BDNF) has recently been identified as a mediator of airway hyper-responsiveness in asthma. METHODS Eighteen patients with mild allergic a...

АСТМА ТА АЛЕРГІЯ, No 4 • 2013 Bronchial asthma (BA) – is a chronic disease caused by increased sensitivity of the bronchi to various kinds of stimulation. BA manifests itself by attacks caused by bronchial obstruction and stop autonomously or as a result of treatment. BA occurs with alternating exacerbations and remissions. During remission the disease may not manifest. Exacerbation is usually ...

Pro-inflammatory cytokine release (IL-8, IL-6, TNF-α, IL-1β) by peripheral blood neutrophils, isolated from periodontitis patients (before/after therapy) and matched controls, was determined after 18 h culture in the presence/absence of Escherichia coli LPS, opsonised Staphylococcus aureus, heat-killed Fusobacterium nucleatum and Porphyromonas gingivalis. All cultures demonstrated differences i...

Fragile X syndrome (FXS) is characterised by hyper-reactivity, autistic tendencies and social anxiety. It has been hypothesised that the FXS social phenotype is secondary to a generalised hyper-reactivity that leads to social avoidance. No study, however, has investigated whether hyperarousal in FXS is generalised or more specific to socially salient information. We recorded skin conductance re...

UNLABELLED BACKGROUND Airway inflammation stimulates proliferation of airway smooth muscle cell, which contributes to the development of hyperplasia and hypertrophy of smooth muscle cell. The increase in airway smooth muscle cell mass is believed to be due to an up-regulation of inflammatory mediators in the airway. It is now well recognized that chronic inflammation as well as airway hyper-...
