Short report: cefprozil for the eradication of Helicobacter pylori infection

Abstract
Helicobacter pylori infection has proven to be extraordinarily difficult to eradicate. Antimicrobial monotherapies have been particularly disappointing, with most eradication rates in the range of 0 to 15%. We evaluated cefprozil (250 mg q.d.s. for 14 days) in 12 H. pylori-infected subjects. The 13C-urea breath test was used to evaluate effectiveness of therapy. Eradication was defined as a negative urea breath test 4 to 6 weeks after the end of treatment. Suppression of H. pylori was demonstrated in 4 of 12 (33%) by a negative urea breath test two days after start of treatment. H. pylori infection was not eradicated in any subject (0%). Adverse events were intermittent and mild. Cefprozil does not appear to offer promise as monotherapy for the eradication of H. pylori.
