Cigarette smoking status alters dysbiotic gut microbes in hypertensive patients.

ABSTRACT: Smoking not only is one of the most important risk factors of hypertension (HTN), but also alters the composition of gut microbiota (GM) in previous studies. Although dysbiosis of GM has been implicated in HTN, how GM alters in patients with HTN under smoking status is still not clear. This study aimed to explore the difference in intestinal microflora among smokers with HTN (S-HTN), nonsmokers with HTN (NS-HTN), and smokers without HTN (S-CTR) and identify whether cigarette smoking led to disordered intestinal microbiota in patients with HTN. Metagenomic sequencing analysis of fecal specimens was conducted in nonsmokers without HTN (NS-CTR, n = 9), S-CTR (n = 9), NS-HTN (n = 18), and S-HTN (n = 23). Compared with S-CTR or NS-HTN, the GM in S-HTN was disordered, with lower microbial α-dive
