title: Effects of killing Helicobacter pylori quadruple therapy on peptic ulcer: a randomized double-blind clinical trial.
abstract: OBJECTIVE
  To study the therapeutic efficacy of a Chinese and Western integrated regimen, killing Helicobacter pylori quadruple therapy on H pylori-associated peptic ulcers (PU).
  
  
  METHODS
  With prospective and double-blind controlled method, seventy-five active PU patients with H pylori infection were randomized to receive one of the following three regimens: (1) new triple therapy (group A: lansoprazole 30 mg qd, plus clarithromycin 250 mg bid, plus amoxycillin 500 mg tid, each for 10 d); (2) killing Hp quadruple therapy(group B: the three above drugs plus killing H pylori capsule 6 capsules bid for 4 wk) and (3) placebo(group C: gastropine 3 tablets bid for 4 wk). H pylori eradication and ulcer healing quality were evaluated under an endoscope 4 wk after treatment. The patients were followed up for 5 years.
  
  
  RESULTS
  Both the healing rate of PU and H pylori eradication rate in group B were significantly higher than those in group C (100% and 96.4% vs 20% and 0%, respectively, P<0.005), but there was no significant difference compared to those in group A (88% and 92%, P>0.05). The healing quality of ulcer in group B was superior to that in groups C and A (P<0.05). The recurrence rate of PU in group B (4%) was lower than that in group A (10%) and group C (100%, P<0.01).
  
  
  CONCLUSIONS
  Killing Helicobacter pylori quadruple therapy can not only promote the eradication of H pylori and healing quality of ulcer but also reduce recurrence rate of ulcer.
