Water-pipe smoking effects on pulmonary permeability using technetium-99m DTPA inhalation scintigraphy

Abstract

We suggest that water-pipe smoking effects pulmonary epithelial permeability more than passive smoking. Increased central mucociliary clearance in water-pipe smoking may be due to preserved humidity of the airway tracts.

Shisha Smoking and Associated Factors among Medical Students in Malaysia

“…In addition, shisha smoke increases heart rate, decreases pulmonary function and it is associated with markers of atherosclerosis as well as increases the risk of coronary heart disease (Jabbou et al, 2003). Other investigators noted impairment of pulmonary function on spirometry (Kiter et al, 2000) and increased pulmonary epithelial permeability (Aydin et al, 2004). Taken together, these reports suggest that shisha smoking has deleterious effects on health and also induces the dependence on nicotine similar to that found in cigarette use (Akl et al, 2010).…”

Investigation of Exclusive Narghile Smokers: Deficiency and Incapacity Measured by Spirometry and 6-Minute Walk Test

“…3 In addition, as ENS are in this environment everyday for at least 100 min, they become passive smokers at the same time. 15 In this study, we chose to evaluate submaximal aerobic capacity using the 6MWT data. (For our justification and for precautions taken during the test, see the supplementary materials at http://www.rcjournal.com.…”

“…This chronic harmful effect, similar to that induced by cigarette smoking, was described previously in several studies. 7,10,[13][14][15][16][17][18][19][20][21][22] Evaluation of Incapacity. Studies on maximal and submaximal aerobic capacities of ENS are rare.…”

“…7,10,[13][14][15][16][17][18][19][20][21]25,29 An example of an acute effect is that a single 30-min session of narghile smoking induced a significant increase in breathing frequency of 2 Ϯ 2 breaths/min. 29 An example of a chronic effect is that of 110 ENS with a Ͼ 1 narghile-year history, 14% had small-airway obstructive ventilatory defects, and 6% had large-airway obstructive ventilatory defects with a significantly higher estimated lung age compared with chronological lung age (47 Ϯ 18 vs 34 Ϯ 10 y).…”

“…[1][2][3][4][5] It is suspected to be a risk factor for a number of acute and chronic tobacco-related defects and/or diseases. [1][2][3][4][5][6][7][8] Among the deleterious effects of narghile use, the chronic cardiorespiratory defects are prominent: [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] exclusive narghile smokers (ENS) have been shown to exhibit worse respiratory and cardiac profiles than healthy non-smokers (HNS) (eg, higher heart rate and systolic (SBP) and diastolic (DBP) blood pressures and lower lung flows and/or volumes). In addition, studies have demonstrated acute (immediate) effects of narghile smoke in the form of increased heart rate, breathing frequency, expired carbon monoxide, SBP, or DBP and a decline in lung function.…”
