[Changes in circulating lymphocyte subsets in alcoholic hepatopathies. Respective role of alcohol, hepatocellular insufficiency and malnutrition].
Peripheral lymphocyte subpopulations have been quantified by a direct and indirect, immunofluorescence technique, using monoclonal antibodies, in 22 patients with continued heavy drinking, hepatocellular dysfunction (spider angiomata, ascites, and factor V decrease) (group I), in 16 patients with a history of heavy drinking and abstinence maintained for at least 6 months and hepatocellular dysfunction (group II) and in 28 patients admitted for continued heavy drinking, without hepatocellular dysfunction (group III). Sixteen normal subjects were studied as controls. The total number of lymphocytes and T lymphocytes (OKT3+) were significantly reduced (p less than 0.001) in groups I and II. A significant decrease of B lymphocytes was observed in group II (p less than 0.02). The OKT8+ lymphocytes were significantly reduced in group I (p less than 0.01) and in group II (p less than 0.001); the decrease of the OKT4+ lymphocytes was significant in group II (p less than 0.01) only. The OKT4/OKT8 ratio was higher in group I (p less than 0.05) and group II (p less than 0.01) than in the control group. Normal values of total lymphocytes, B lymphocytes, T lymphocytes subsets and OKT4/OKT8 ratio were observed in group III. In group III, the lymphocyte subpopulations and OKT4/OKT8 ratio were similar in patients with or without abnormalities of liver function tests. In group I and II, no correlation was found between the lymphocyte subpopulations or the OKT4/OKT8 ratio and factor V or nutritional status assessed by anthropometrical and biological tests. T-cell imbalance in alcoholic liver disease does not seem to be related to alcohol consumption, factor V decrease or malnutrition.
