Common variable immunodeficiency, abbreviated CVID, is a group of genetic disorders characterized by deficient antibody production.

General

Features:[1]

Gross

Duodenum:

  • Nodular mucosa - due to lymphoid hyperplasia.

Microscopic

Features - general:

  • Plasma cells absent (or reduced) - key feature.[1]
  • +/-Lymphoid aggregates.
  • +/-Granulomatous disease ~8-22%.[2]

DDx:

Features by site in the GI tract:[3]

Site Features
Esophagus intraepithelial PMNs & candida +/-abundant intraepithelial lymphocytes
Stomach lack of plasma cells (~2/3 of individuals), lymphoid aggregates (common), +/-lymphocytic gastritis, +/-intraepithelial neutrophils, +/-infections (CMV, H. pylori, cryptosporidium)
Small bowel villous blunting (>80% of individuals), decreased plasma cells (~2/3 of individuals), lymphoid aggregates (~1/2 of individuals), +/-neutrophils + infections (CMV, cryptosporidium)
Large bowel decreased plasma cells, lymphoid aggregates, +/-apparent apoptosis
