Question 5 of 5
The patient described in the preceding questions has a positive H. pylori antibody blood test. She is compliant with the medical regimen you prescribe. Although her symptoms initially respond, she returns to see you six months later with the same symptoms. Which of the following statements is correct?
Correct Answer: C
Rationale: Reinfection by H. pylori is rare, and the persistence of infection usually indicates poor compliance with the medical regimen or antibiotic resistance. The serum IgG may remain positive indefinitely and cannot be used to determine failure of eradication; however, a fall in quantitative IgG levels has been used to document treatment success. If available, either the stool antigen or urease breath test is ideal to document treatment failure because of their high sensitivity and specificity and because they are easy to perform. The association between dyspepsia and H. pylori is hotly debated, but for the most part, dyspepsia does not usually improve with H. pylori eradication.
