Delayed cutaneous hypersensitivity was studied in 10 patients with severe alcoholic hepatitis, 9 patients with either inactive alcoholic cirrhosis or alcoholic fatty liver, and 10 agematched controls. The mean response of the alcoholic hepatitis group was significantly less compared to controls for SK-SD (P less than 0.001), mumps (P less than 0.001), trichophyton (P less than 0.025), and Candida albicans (P less than 0.025). Upon clinical recovery, the response of the 6 surviving patients with alcoholic hepatitis was similar to controls for 4 of the 5 antigens tested, and the improvements in response to SK-SD and Candida albicans were significant (P less than 0.02 and P less than 0.05). The mean percentage and absolute numbers of thymus-derived lymphocytes were significantly less in the alcoholic hepatitis group compared with controls. Both the alcoholic hepatitis patients and patients with less advanced alcoholic liver disease had a diminished response to concanavalin A and phytohemagglutinin. This study demonstrates a reversible depression of delayed cutaneous hypersensitivity in alcoholic hepatitis. Several mechanisms may help account for this finding. We recommend that skin tests in patients with alcoholic hepatitis be interpreted with this phenomenon in mind.
