1B). The 1-, 5-, and 10-year death-adjusted cumulative incidences of recurrent PUB were 14.4% versus 11.3%, 26.1% versus 22.5%, and 28.4% versus 27.1%, respectively, in the cirrhosis PD-0332991 purchase cohort compared with controls (P < 0.0001). The modified Cox proportional hazard model revealed that recurrent PUB was independently associated with cirrhosis, age, sex, prescription of antisecretory
drug, use of propranolol, acute coronary syndrome, and interaction terms of cirrhosis with age, cirrhosis with ulcerogenic medication, and antisecretory agent with ulcerogenic drug (Table 2). Although liver cirrhosis (adjusted HR, 3.19; 95% CI, 2.62-3.89) and older age (adjusted HR, 1.00; 95% CI, 1.00-101) were independent risk factors for peptic ulcer rebleeding, they interacted with each other in an intriguing way to reduce the risk (adjusted HR, 0.98;
95% CI, 0.98-0.98). The multivariate stratified analysis demonstrated that cirrhosis was associated with risk of recurrent PUB nearly in all subgroups, except in the stratum according to age (Fig. 2). The association between liver cirrhosis and recurrent PUB appeared in opposite directions across age groups, with raised risk in patients <60 years of age and paradoxically reduced risk in patients ≥60 years of age. In addition, we also found that alcoholic etiology was associated with a higher 10-year cumulative incidence of recurrent bleeding (32.8% versus 24.2%; P < 0.0001) in our cirrhotic cohort (Supporting Fig. 2). Nonetheless, patients' previous experience with AVH was unrelated to subsequent risk of PUB (27.8% versus http://www.selleckchem.com/products/azd5363.html 28.9%; P = 0.147; Supporting Figs.
3 and 4). The rebleeding risk of the cirrhosis cohort decreased with increased age, from 32.9% in patients 20-39 years of age 上海皓元医药股份有限公司 to 23.4% in patients >60 years of age, whereas that of controls increased from 22.6% to 28.9% in the same respective age groups (Fig. 3). Because death was the competing cause of risk, the paradoxical interaction between cirrhosis and age resulted from the strikingly rising probability for mortality happening ahead of rebleeding when patients with cirrhosis aged (Fig. 4). In other words, patients who had cirrhosis and were of advanced age (>60 years) had a lower chance of PUB recurrence (P = 0.0128) compared with controls, because they were far more likely to die than to experience peptic ulcer rebleeding (Fig. 4C). If the estimates had been performed with noninformative censoring of death, the cirrhosis cohort would have had similarly high risk of recurrent bleeding irrespective of age (Supporting Fig. 5). This population-based cohort study demonstrates for the first time that the long-term risk of recurrent PUB is significantly increased in patients with liver cirrhosis. We found that cirrhosis was associated with an adjusted hazard ratio of 3.19 (95% CI, 2.62-3.
