Narghile (water pipe) smoking influences platelet function and (iso-)eicosanoids

Area of Science:

• Biochemistry
• Physiology
• Toxicology

Background:

• Water pipe (Narghile) smoking is a widespread practice globally, affecting approximately 1 billion people.
• The biological effects of water pipe smoking on haemostasis and the eicosanoid system remain largely unknown.
• Understanding these effects is crucial due to the extensive global prevalence of water pipe use.

Purpose of the Study:

• To investigate the potential effects of Narghile smoking on oxidative injury.
• To monitor specific parameters of the (iso)eicosanoid system in response to water pipe smoking.
• To assess the impact on haemostasis markers.

Main Methods:

• Seven healthy, non-cigarette smoking males participated in the study.
• Participants smoked a water pipe once daily for 14 days.
• Blood samples were collected multiple times: before and after the first smoking session, 6 hours later, and at 1 and 2 weeks post-smoking (before and after sessions).
• Measured parameters included in vivo oxidation injury markers (8-epi-PGF2alpha, malondialdehyde [MDA]) and a haemostasis marker (11-dehydro-thromboxane B2 [11-DH-TXB2]).

Main Results:

• A single water pipe smoking session significantly increased markers of oxidation injury (8-epi-PGF2alpha, MDA) and 11-dehydro-thromboxane B2.
• Repeated daily smoking resulted in persistent, long-lasting oxidative injury.
• Elevated pre-smoking baseline values were observed with repeated use, indicating chronic oxidative stress, though the acute response to smoking diminished.

Conclusions:

• Regular water pipe smoking significantly increases in vivo oxidative stress.
• The findings suggest that water pipe smoking poses a considerable risk for oxidative damage.
• Further research is warranted to understand the long-term health implications of water pipe smoking on haemostasis and the eicosanoid system.
