We found higher frequencies of IL-22-producing T helper cells in AH patients (median 1.7%) than in cirrhosis patients (1.0%, p = 0.03) and healthy controls (1.0%, p = 0.01), and a 1.5-fold increase in the plasma concentration of IL-17A in AH compared with healthy controls (p<0.01). The gene discussed is IL17A; the disease is Cirrhosis.
