Abstract
Background
Inducible nitric oxide synthase (iNOS) single-nucleotide polymorphisms have been reported to confer susceptibility to hypertension, but no consensus has been reached. The aim of this study was to investigate the association between iNOS and hypertension in a Chinese population.
Methods
This was a case-control study including 1172 hypertensive and 1172 control subjects to investigate the association between iNOS and hypertension.
Results
There were significant differences in the distribution of genotype and allele frequencies of rs2779249 and rs2297518 between hypertensive and normotensive subjects. Logistic regression analyses were performed with different genetic models (additive, dominant, recessive) adjusting for confounding risk covariates, including age, sex, body mass index, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, smoking, drinking, and family history of hypertension. The odds ratio (OR) was 1.27 (1.12, 1.44) in the additive model, 1.31 (1.09, 1.59) in the dominant, and 1.68 (1.28, 2.19) in the recessive model of rs2779249; the OR was 1.26 (1.06, 1.50) in the additive model and 1.46 (1.13, 1.89) in the dominant model of rs2297518.
Conclusion
The current study provides evidence that iNOS is strongly associated with hypertension.
Zusammenfassung
Hintergrund
Von Einzelnukleotidpolymorphismen der induzierbaren Stickstoffmonoxidsynthase (iNOS) wird berichtet, dass sie mit der Neigung zur Hypertonie einhergehen, darüber herrscht jedoch noch kein Konsens. Ziel der vorliegenden Studie war es, den Zusammenhang zwischen iNOS und Hypertonie in einer chinesischen Population zu untersuchen.
Methoden
Es handelt sich um eine Fall-Kontroll-Studie zur Untersuchung des Zusammenhangs zwischen iNOS und Hypertonie an 1172 Teilnehmern mit Hypertonie und 1172 Kontrollen.
Ergebnisse
Zwischen Teilnehmern mit Hypertonie und Kontrollen mit Normotonie bestanden signifikante Unterschiede in Bezug auf die Verteilung der Genotyp- und Allelhäufigkeiten von rs2779249 und rs2297518. Logistische Regressionsanalysen wurden mit verschiedenen genetischen Modellen (additiv, dominant, rezessiv) durchgeführt, unter Berücksichtigung von störenden Risikokovariaten wie Alter, Geschlecht, Body-Mass-Index, Gesamtcholesterin, Triglyzeride, High-Density-Lipoprotein-Cholesterin, Low-Density-Lipoprotein-Cholesterin, Rauchen, Alkohol und Hypertonie in der Familienanamnese. Die Odds Ratio (OR) betrug 1,27 (1,12; 1,44) im additiven Modell, 1,31 (1,09; 1,59) im dominanten und 1,68 (1,28; 2,19) im rezessiven Modell von rs2779249; die OR lag bei 1,26 (1,06; 1,50) im additiven Modell und bei 1,46 (1,13; 1,89) im dominanten Modell von rs2297518.
Schlussfolgerung
Die vorliegende Studie liefert Hinweise darauf, dass ein deutlicher Zusammenhang zwischen iNOS und Hypertonie besteht.
