Seventy-two patients with recently healed gastric ulcers were entered into a double-blind, placebo-controlled, six-month maintenance trial to assess whether sucralfate, 1 g in the morning and 2 g at night, reduces the propensity for recurrent ulceration. Patients were assessed clinically at 0, 6, 12, 18, and 24 weeks. Endoscopy was performed at the time of entry into the study and at 24 weeks, or earlier if clinical relapse occurred during this period. Eleven patients were excluded from the study because they defaulted or for other protocol violations. The other 61 patients were followed for six months or until evidence of ulcer relapse. Endoscopic recurrence was found in five of 31 patients (16 percent) randomly assigned to receive sucralfate and in 21 of 30 patients (70 percent) assigned to receive placebo. Most recurrences occurred during the first 12 weeks, with relapse rates of 10 percent and 53 percent, respectively for the sucralfate- and the placebo-treated groups. Three of the recurrences noted at 24 weeks were asymptomatic; two of these were in the sucralfate-treated group. The results indicate that a 3 g per day maintenance dose of sucralfate offers meaningful protection against recurrent gastric ulceration.
72例近期胃溃疡已愈合的患者进入一项双盲、安慰剂对照的为期6个月的维持治疗试验,以评估每天早上1 g、晚上2 g的硫糖铝是否能降低溃疡复发倾向。在第0、6、12、18和24周对患者进行临床评估。在研究开始时以及24周时进行内镜检查,若在此期间发生临床复发则提前进行内镜检查。11例患者因未按时就诊或违反其他研究方案而被排除在研究之外。其余61例患者随访6个月或直至出现溃疡复发迹象。随机分配接受硫糖铝治疗的31例患者中有5例(16%)出现内镜下复发,分配接受安慰剂治疗的30例患者中有21例(70%)出现内镜下复发。大多数复发发生在最初12周内,硫糖铝治疗组和安慰剂治疗组的复发率分别为10%和53%。24周时记录的复发中有3例无症状,其中2例在硫糖铝治疗组。结果表明,每天3 g的硫糖铝维持剂量对预防复发性胃溃疡有显著保护作用。
