A decrease of human leucocyte antigen‐DR expression on monocytes in peripheral blood predicts stroke‐associated infection in critically‐ill patients with acute stroke

Human leucocyte antigen-DR (HLA-DR) expression decreases and sustains a dynamic change and it also relates to the severity of patient's condition in the critically-ill patients with stroke. Progressively persistent low monocyte HLA-DR expression is associated with a poor prognosis. The decline in HLA-DR expression contributes to infection in critically-acute stroke patients. Monitoring of monocyte HLA-DR expression may be useful for identifying patients suffering from acute stroke who are at high risk for infection.
