BACKGROUND
The aim of this study was to evaluate the relationship between airway hyperresponsiveness (AHR) to mannitol and bronchial inflammation measured as exhaled nitric oxide (FeNO) and to assess whether asthma control correlates with AHR to mannitol and FeNO in atopic asthmatic
OBJECTIVE
The purpose of this study was to demonstrate and compare the diagnostic validity of two bronchial challenges and to investigate their correlation with patient clinical status, atopy and inflammation markers.
METHODS
Eighty-eight patients, 47 women and 41 men, mean age 38.56 ± 16.73 years
The hexahydric alcohol mannitol is widely used to shift fluids from the intracellular to the extracellular compartments, to increase diuresis and improve mucus clearance in the airways. In principle, because of its physicochemical properties, topical mannitol might also draw fluids out of epidermis
BACKGROUND
Mannitol is a novel osmotic indirect bronchial challenge agent used to aid asthma diagnosis and management and is thought to reflect underlying inflammatory processes in asthma. Our objective was to evaluate relationships between mannitol airway hyperresponsiveness (AHR) and other
OBJECTIVE
Eosinophilic bronchitis (EB) shares many pathological features with asthma. However, patients with EB do not develop the characteristic physiological abnormalities of asthma: variable airflow obstruction and bronchial hyperresponsiveness (BHR) to a direct bronchial challenge with
BACKGROUND
There has been substantial debate regarding the efficacy of hypertonic saline (HTS) versus mannitol (MTL) in treating moderate and severe traumatic brain injury (TBI). HTS blunts polymorphonuclear neutrophil (PMN) and endothelial cell (EC) activation and reduces tissue edema after
Asthma may be defined as eosinophilic or non-eosinophilic based on the presence of eosinophils in sputum. Recently a further classification into four inflammatory subtypes has been suggested. The aim of the present study was to describe the association between these inflammatory subtypes and markers
Sugar alcohols, such as mannitol and xylitol, are biocompatible polyols that have been used to make highly cross-linked polyester elastomers and dendrimers for tissue engineering and drug delivery. However, research that utilizes the secondary hydroxyl groups as sites for pendant bioactive
BACKGROUND
Eosinophilic airway inflammation has successfully been used to tailor anti-inflammatory therapy in chronic obstructive pulmonary disease (COPD). Airway hyperresponsiveness (AHR) by indirect challenges is associated with airway inflammation. We hypothesized that AHR to inhaled mannitol
Increased intestinal permeability has been proposed as one aetiological factor for inflammatory bowel diseases (IBD). We have previously found that intestinal permeability of a water-soluble contrast medium, iohexol, correlates with disease activity. The objective was to compare the iohexol test
BACKGROUND
Airway hyperresponsiveness (AHR) to stimuli that cause bronchial smooth muscle (BSM) contraction indirectly through the release of endogenous mediators is thought to reflect airway inflammation more closely compared with AHR measured by stimuli that act directly on
BACKGROUND
Spontaneous intracerebral hemorrhage (ICH) leaves most survivors dependent at follow-up. The importance of promoting M2-like microglial responses is increasingly recognized as a key element to ameliorate brain injury following ICH. The osmotherapeutic agents, mannitol and hypertonic
BACKGROUND
Assessment of airway inflammation in asthma is becoming increasingly important, as the inflammatory phenotype underpins the treatment response.
OBJECTIVE
This study aimed to evaluate mannitol as a tool for assessing airway responsiveness and airway inflammation in asthma, compared with
BACKGROUND
Airway hyperresponsiveness (AHR) to inhaled mannitol is associated with indirect markers of mast cell activation and eosinophilic airway inflammation. It is unknown how AHR to mannitol relates to mast cell phenotype, mast cell function and measures of eosinophilic inflammation in airway
A direct comparison was made between mannitol-lactulose and EDTA tests in 10 control subjects and in 9 and 19 patients suffering, respectively, from ulcerative colitis or Crohn's disease. The markers were orally administered in a random order and urinary recoveries were measured. At group level,
