Wetenschappelijk onderzoek

Het protocol voor de behandeling van astma is op basis van wetenschappelijke publicaties ontwikkeld. Hierbij is gebruik gemaakt van de National Library of Medicine (PubMed). Daar waar mogelijk werden studies die opgezet zijn volgens het “placebo controlled cross-over” principe gebruikt. Andere vormen die vaak werden gebruik zijn reviews en epidemiologisch onderzoek. Publicaties uit bladen als The Lancet, American Journal of Cardiology, The New England Journal of Medicine hadden de voorkeur

      Both NNF and control groups demonstrated improvement in asthma-free days. NNF-treated group had reduced biomarkers of disease activity. Rapid PBMC fatty acid composition changes reflected an anti-inflammatory profile. Dietary supplementation with NNF was safe and well tolerated.[Abstract]

      The dietary addition of the medical food EFF1009 to asthma management regimens can improve patient perceived, ARQOL and can also improve asthma management as evidenced by reduced asthma symptoms.

      Whole blood, but not plasma or sputum, carotenoid levels are deficient in asthma. Plasma carotenoid levels reflect airway carotenoid levels and when plasma levels are improved using oral supplements this is reflected in the airways.[Article]

      We conclude that asthmatic subjects with AHR, uncontrolled asthma and a severe asthma pattern have impaired antioxidant defences and are thus most susceptible to the damaging effects of oxidative stress. This highlights the potential role for antioxidant supplementation in these subjects.[Abstract]

        Lower GSH-Px activity in children with controlled asthma showed deficient erythrocyte antioxidant defence and evidence of association between oxidative stress and asthma in childhood. Preserved activity of GR and SOD, together with concentration of GSH and MDA, still seems to be crucial in controlling antioxidant/oxidant balance of the disease.[Abstract]

        BA patients have a marked imbalance between production of active oxygen forms and activity of intracellular antioxidant enzymes. This evidences for low adaptive and defense processes leading to the oxidative stress which is one of the leading links in BA pathogenesis. Oral GT reduced extracellular oxidative status, inhibited activity of intracellular antioxidative enzymes. Inhalation GT had no negative systemic action on antioxidant enzymes.[Abstract]

        Magnesium sulfate, 1.2 g over 20 minutes after beta-agonist administration, is safe and modestly efficacious in the treatment of acute exacerbations of chronic obstructive pulmonary disease, and its bronchodilator effect is greater than that of a beta-agonist given alone and lasts beyond the period of magnesium sulfate administration.[Abstract]

        Ascorbic acid supplementation provides a protective effect against exercise-induced airway narrowing in asthmatic subjects. [Abstract]

      2. We conclude that while vitamin C supplements may have modest corticosteroid sparing effects and hence the potential to reduce exposure to their side effects, magnesium supplements have no effect on the inhaled corticosteroid dose required to maintain asthma control.[Abstract]

        After 14 weeks, an assessment of the severity and rate of attacks showed that those on ascorbic acid suffered less severe and less frequent attacks of asthma during the study period. Plasma ascorbic acid astimations showed a significant rise in the level in those taking ascorbic acid over those on placebo. (P < 0.01). Cessation of ascorbic acid in the group taking it increased attack rates. It is concluded that high dose ascorbic acid is probably a good prophylaxis in some bronchial asthmatics.[Abstract]

        Plasma concentration of ascorbic acid was determined in fifty-one asthmatic children and a group of matched controls. The mean ascorbic acid level of 0.54 mg/100 ml among the asthmatics was significantly lower than a mean of 0.84 mg/100 ml for controls (P less than 0.001). Ascorbic acid level was directly related to the socio-economic class (SC) since asthmatic children from SC I, II and II had significantly higher ascorbic acid levels than those from SC IV and V.[Abstract]

        These data suggest that different petasins may at least partially block different intracellular signalling molecules. To reduce LT synthesis, isopetasin and neopetasin may act at the level of or distal to 5-LO. In contrast, petasin may inhibit inflammatory effector functions in human eosinophils by disrupting signalling events at the level of or proximal to phospholipase Cbeta (PLCbeta), besides its potential inhibitory activity within mitogen-activated protein kinase (MAPK) and LT pathways.[Abstract]

        There is some indication that selenium supplementation may be a useful adjunct to medication for patients with chronic asthma. This conclusion is limited because of insufficient studies and lack of improvement in the clinical parameters of lung function.[Abstract]

        There was also a significant reduction of urinary leukotrienes in the Pycnogenol group. The results of this study demonstrate the efficacy of Pycnogenol as an adjunct in the management of mild-to-moderate childhood asthma.[Abstract]

        Since they appear to have differing effects on activated cells, the anti-inflammatory effects of CyA and BN52021 in atopic asthma is potentially additive. The present approach may be useful for preliminary evaluation of novel therapeutic modalities for asthma treatment.[Article]

        The findings support the possible role of specific PAF-acether antagonists in the treatment of asthma.[Abstract]

        The results showed the following: (1) six of seven asthmatics and one of seven normal subjects gave a positive bronchial provocation with PAF; (2) in asthmatics, prior inhalation of BN52021 could inhibit the bronchoconstriction induced by PAF (6/6) and allergen (3/7), but not by methacholine; and (3) 5 min after inhalation of PAF, there was a marked decrease of peripheral blood eosinophils and neutrophils that could be inhibited by prior inhalation of BN52021 in normal subjects but not in asthmatics. These findings support the idea that PAF may be involved in the pathogenesis of bronchial asthma and PAF antagonist may have a role in the prevention and treatment of this disease.[Article]

        The results show that platelet activation after exercise induced asthma was markedly inhibited by BN 52063, indicating that PAF acts as a mediator in exercise induced asthma.[Abstract]

        This review concludes that the data are sufficient to warrant a clinical trial that is properly controlled and randomized to further investigate the influence of dietary salt intake on pulmonary function, airway responsiveness, symptoms, quality of life, and medication requirements in asthma and EIB.
