The ELISA with use of IgG, IgA, and IgE, latex agglutination, indirect hemagglutination (IHA), total IgE, the radioallergosorbent test (RAST), and immunoelectrophoresis (IEP) were carried out to determine the preoperative diagnosis of infection due to Echinococcus granulosus in 131 patients. Eighty-nine patients received follow-up care for 42 +/- 22 months (mean +/- SD); 72 were treated surgically and 17 with mebendazole only. We analyzed 5 +/- 2 serum samples per patient and analyzed each serum sample using the eight tests. IgG ELISA was the most sensitive (up to 94%) and specific (up to 99%) test for the majority of cyst locations in the patient. IEP was positive in only 73% of cases. The combination of IgG ELISA, IHA, and IgA ELISA allowed us to achieve a sensitivity of 81% in cases of pulmonary echinococcosis. IgE and IgA were both responsible for most nonspecific reactions, the former in patients with parasitic diseases other than echinococcosis and the latter in patients with cirrhosis of the liver and malignancies. IgG ELISA and IHA were the most adequate tests for postsurgical follow-up. In patients with favorable clinical outcome, the specific IgG level decreased early toward the end of the first year, although serological positivity could persist beyond 6 years. A rise of IgG level 2 or 3 years after treatment suggested persistent active infection. In patients with mebendazole-associated cure, only tests with total or specific IgE detection seemed to exhibit a strong association with decreasing levels or with negative results.

The aetiology of idiopathic portal hypertension or hepatoportal sclerosis is unknown. In view of the indirect evidence for underlying immunologic abnormalities 14 patients (all middle-aged females) were studied. Various auto-antibodies were demonstrated in seven patients and high levels of serum immunoglobulins, either IgG, IgM or IgA were present in ten patients. T cell responsiveness to stimulation with either autologous or allogeneic non-T cells was examined in nine of 14 idiopathic portal hypertension patients and compared with responsiveness in patients with posthepatitic cirrhosis and splenomegaly, and healthy controls. Patients with cirrhosis had levels of T cell responsiveness which were not significantly different from those in healthy controls in both autologous and allogeneic mixed lymphocyte reactions. A distinctly reduced autologous mixed lymphocyte reaction was observed in all idiopathic portal hypertension patients. These data indicate that, like many other autoimmune diseases, abnormal serological features and impaired autoreactive T cell responsiveness exist in patients with idiopathic portal hypertension.

Antibodies to gliadin IgA (IgA-AGA) were detected by enzyme-linked-immunosorbent-technique (ELISA) in 30 healthy controls, 20 coeliac patients and 25 patients with non coeliac malabsorption. All the controls had levels of IgA-AGA in the normal range (25AV). Three of the 25 patients with non coeliac malabsorption presented high titres of IgA-AGA. Thirty six determinations of IgA-AGA were made on the coeliac patients. All but one of the determinations made during the symptomatic phase of the disease were 25AV. The highest titres corresponded either to untreated patients or patients with complications (cirrhosis, lymphoma). In our study the sensitivity and the specificity of the test for symptomatic patients were 94.4% and 94.5% respectively.

We conducted a prospective study of renal histology and function in 18 consecutive nonalcoholic patients who underwent orthotopic liver transplantation (OLT). Despite well-preserved renal function, all patients had abnormal renal biopsies. Four patterns of glomerular injury were identified: minor glomerular abnormalities (eight patients), hepatic glomerulosclerosis (seven), membranoproliferative glomerulonephritis (one), and IgA nephropathy (one). In one patient there was insufficient tissue to allow classification. There was a trend toward lower plasma bilirubin and higher plasma albumin in patients with minor glomerular abnormalities than in the group of patients with more severe forms of glomerular injury (29 v 82 mumol/L, 35.5 v 30 g/L; P = 0.1, 0.1 greater than P greater than 0.05, respectively). Glomerular changes persisted in the three patients who died within 7 weeks post-OLT. IgM immunofluorescence was present in all biopsies and IgA in 11. IgM-containing circulating immune complexes occurred in five patients, suggesting a pathogenic role for IgM immune complex deposition. The significance of cirrhosis-associated glomerular abnormalities is not yet known. They may contribute to the hepatorenal syndrome and the renal dysfunction that occurs in up to 94% of patients post-OLT.

The study involved 85 patients with alcohol-produced liver cirrhosis divided into two groups depending on the presence or absence of HBV infection serological markers (HBV+-51; HBV-34). The study was aimed at comparing selected indices of both humoral and cell-mediated reactions in the blood of patients with alcohol-produced liver cirrhosis depending on immuno-serologically confirmed infection with HBV. Statistically significant differences between both groups concerned percentage of OKT4 (HBV+-67.7%; HBV--58.4%), and complement component C4 (0.32 and 0.48 g/L, respectively). Moreover, a significant decrease in percentage of T-cell and significant increase in IgG, IgA, IgM, and immunological complexes levels were noted when comparing with normal values. Results indicate, that the immunopathological reactions resulting from action of the two most frequent, harmful, hepatotropic, factors, i.e. alcohol and HBV, are different.

Immunoglobulin (Ig) serum levels have been assayed in 729 patients with liver cirrhosis of different etiologies, in order to evaluate their prognostic value. Serum levels of three classes of Ig resulted mainly elevated in the three etiological groups (post-hepatitic, post-alcoholic, cryptogenetic) and they were significantly related to the severity of the liver disease, evaluated according to the Child-Turcotte score. The computerized analysis of the survival curves of patients with IgG, IgM, IgA values normal or elevated demonstrated an adverse prognostic rate in those with elevated Ig values. The difference among the survival curves, compared by the Lee-Desu method, was statistically significant (p less than 0.001). Our data suggest that the Ig levels can be considered as a prognostic index in liver cirrhosis patients.

The aim of our study is to prove whether the development of the low-T3-syndrome in patients with liver cirrhosis is associated with their prognosis. For this purpose we determined the peripheral thyroid hormone levels in 28 patients with liver cirrhosis. For prognosis assessment we calculated the Prognostic Index (PI) on the basis of Cox's regression model as recently described by us. Calculating this index we used 11 parameters: liver morphology, consciousness, spider naevi, PCV, thrombocytes, gamma-GT, cholesterol, albumin, Quick's value, IgA, and potassium. It is demonstrated that there is an inverse correlation between T3-serum levels and PI (p = 0.03). An association could not be detected neither between reverse T3 and PI nor between T3 and rT3. On the other hand basal TSH was also inversely associated with PI. Thus, the low T3-serum levels did not induce a rise of basal TSH in cirrhotics. Moreover, the mean serum-T3-concentration differed significantly from that of 6 decreased patients and from that of the surviving (p = 0.00076). It seems to be true that low T3-serum levels are a very sensitive parameter for prognosis prediction in patients with liver cirrhosis.

Renal glomerular changes are a well recognised complication of cirrhosis and are frequently characterised by mesangial IgA deposition. We report a patient with non-cirrhotic portal hypertension who developed IgA nephropathy and a nephrotic syndrome with renal histological changes classically associated with cirrhosis. Splenectomy with resection of a splenic artery aneurysm resulted in remission of the nephrotic syndrome. This case illustrates the factors which contribute to the pathogenesis of IgA nephropathy in liver disease.

We have determined the individual kappa (kappa)/lambda (lambda) ratios of serum IgG, IgA, and IgM in normal subjects and patients with rheumatoid arthritis, systemic lupus erythematosus, hepatic cirrhosis and IgA nephropathy--40 in each group. Serum samples were first screened by agarose electrophoresis to exclude paraproteinaemia. Concentrations of IgG, IgA, and IgM were determined by enzyme-linked immunosorbent assay (ELISA). The kappa and lambda chain concentrations of each immunoglobulin class were assayed by an ELISA method first developed by us for the determination of kappa/lambda ratios. Our results showed that kappa/lambda ratios of serum IgA and IgM were significantly different from that of IgG in normal subjects and the 4 groups of patients studied (p less than 0.01). The kappa/lambda ratios of individual immunoglobulins in patients with rheumatoid arthritis, systemic lupus erythematosus and liver cirrhosis were similar to those of normal subjects. However, patients with IgA nephropathy displayed a distinctly lower IgA kappa/lambda ratio, suggesting a unique antibody response in the immunopathogenesis of this disease.

A histopathologic and immunofluorescence study of the choroid plexus was performed in 12 cases of liver cirrhosis (cirrhosis group) and in 20 patients who died of diseases with no evidence of liver or brain involvement, and in which renal disease and alcoholism were also excluded (control group). IgA, IgG, IgM, C3, and C1q were investigated by direct immunofluorescence technique. Positive immunofluorescence in the choroid plexus was found in 83.33% of the cirrhosis group. IgA and IgG were the immunoglobulins more frequently found. C3 was also commonly found. Histologic examination of the choroid plexus showed changes in 66.67% of the cirrhosis group characterized, mainly, by subepithelial deposition of a homogeneous, acidophilic, and periodic acid-Schiff-positive substance, with thickening of the epithelial basement membrane. In the control group, the immunofluorescence in the choroid plexus was negative in all cases and only two cases (10%) presented histopathologic changes of the choroid plexus with a pattern similar to that of the cirrhosis group.
