Instructions: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Input: Abstract: In 66 endoscopic duodenal biopsies studied retrospectively and in 84 paired duodenal and antral biopsies assessed prospectively campylobacter like organisms were seen in 22 (33%) of the retrospectively examined duodenal biopsies and in 61 (73%) examined prospectively, and in 70 (83%) of antral biopsies. In the duodenum the organisms were mostly confined to the surface epithelium in areas showing gastric metaplasia, while in the antrum they were also found within superficial glands. A strong association was shown between the presence of campylobacter like organisms and histological active duodenal inflammation.
Which is the apt title for the abstract? option1: Campylobacter like organisms in duodenal and antral endoscopic biopsies: relationship to inflammation. option2: Medical care costs of patients with AIDS in San Francisco.
Output:
Campylobacter like organisms in duodenal and antral endoscopic biopsies: relationship to inflammation.
