title: [Normal gamma globulin levels in liver cirrhosis: a prognostic indicator and improved survival].
abstract: Serum levels of gammaglobulins were evaluated in a population of 1334 patients with liver cirrhosis (mean age +/- SD 54.8 +/- 10.9; 898 males). Hypergammaglobulinemia was not as frequently observed as described in the literature 278 patients (20.8%) had gammaglobulin levels lower than 1.5 g/dl (first group) and the other 1056 had more than 1.5 g/dl of gammaglobulins (second group). At analysis of survival curves the first group had a median survival time of over 60 months, significantly higher than the 37.6 months of the other patients, when compared with the Lee-Desu statistic (p less than 0.01). Moreover, the patients of the first group had a lower incidence of ascites as compared to the second group (28% versus 45%; p less than 0.001), hepatic encephalopathy (7% versus 14%; p less than 0.01) and hepatocellular carcinoma (5.7% versus 8.4%; n.s.). The presence and the degree of oesophageal varices were significantly lower in the patients of the first group than in the others (p less than 0.001); a number of laboratory tests for the evaluation of liver cell function and the Child class distribution were more favourable in the first group than in that of hypergammaglobulinemic patients.
  
  
  CONCLUSIONS
  normal blood gamma globulin level is not uncommon in liver cirrhosis and it may be considered a positive prognostic factor, which identifies a group of patients with a better quality of life, a lower incidence of decompensation symptoms and a longer survival time.
