[Chronic active plasmacytic gastritis associated with cytomegalovirus].
Chronic active plasmacytic gastritis (CAPG) is characterized by the presence of chronic inflammatory cell infiltrates, mainly formed by plasma cells, involving the neck of gastric glands. This lesion, as well as Ménétrier disease, has been linked to cytomegalovirus (CMV). To test this association we evaluated the foveolar/glandular (F/G) index and the presence of CMV DNA (desoxirribonucleic acid) by means of polymerase chain reaction (PCR) in 12 cases of CAPG and 13 controls. Cases exhibiting CAPG included 2 with Ménétrier disease, 6 with foveolar hyperplasia, and 3 with normal foveolar/glandular (F/G) index. None showed either lymphocytic gastritis or CMV inclusions. Three CAPG cases were associated with gastric carcinoma. The F/G index was less than 1 in all controls. Eleven out of the 12 cases with CAPG showed amplification for CMV DNA while all controls were negative. Findings suggest a very close association, probably in progressive stages, between CMV infection, CAPG, foveolar hyperplasia (with or without Ménétrier disease) and gastric carcinoma. CAPG might be a histologic marker for CMV infection in the germinative zone of the neck of gastric glands. These findings resemble those of hepatitis B virus (HBV) infection, chronic hepatitis, cirrhosis, and hepatocellular carcinoma saga.
