Pathophysiology
The pathophysiology of nocturnal asthma is closely associated with the chronobiology and the science of biologic processes that have time-related rhythms.
- Alterations in beta2-adrenergic[1][2] and glucocorticoid receptors[3] and hypothalamic-pituitary-adrenal axis function have shown to play a role in modulating the nocturnal asthma phenotype, and recent studies have suggested elevation and phase delay of peak serum melatonin,[4] a neurohormonal controller of circadian rhythms, to play an important role in the pathogenesis of nocturnal asthma.[5][6]
- The increase of CD51 at night, in patients with nocturnal asthma, may be related to increased airway inflammation and repair processes in response to injury.[7]
- Research has demonstrated that the greatest inflammation in nocturnal asthmatics occurs in the proximal alveolar tissue at 4 AM. Inflammatory mediators such as eosinophils, macrophages and CD4+ lymphocytic infiltration, were shown to accumulate in the proximal alveolar tissue and contribute to the variation in lung function.[8][9]
- The development of nocturnal airway obstruction in asthma has been associated with the enhanced production of oxygen radicals by air-space cells. Because oxygen radicals can cause airway injury and thus enhance bronchial obstruction, it has been postulated that the release of these reactive compounds is causally associated with nocturnal asthma.[10][11][12]
- Worsening of nocturnal asthma has been associated to the secondary increase in the levels of inflammatory mediators such as leukotrienes, interleukins, and histamine.[10][13][14][15][16][17]
- Enhanced parasympathetic activity is associated with bronchial hyper-reactivity, which is characteristic of asthma. It is believed this increased cholinergic tone may be related to the pathogenesis of bronchial asthma.[18][19]
Asthma and Obstructive Sleep Apnea
- It is recognized with increasing frequency, that patients who have both obstructive sleep apnea and bronchial asthma, often improve tremendously when the sleep apnea is diagnosed and treated.[20][21]
- However, CPAP has not shown to be effective in patients with nocturnal asthma alone.[22]
