[The significance of lobular inflammation in chronic active hepatitis].

Authors have performed an anatomo-clinico-biological comparison of two groups of hepatitis with lobular inflammation: group I with a simple lobular inflammation, called lobular hepatitis, and group II with a lobular inflammation associated with portal and periportal hepatitis, called chronic active hepatitis (CHA) with lobular hepatitis. Furthermore, a comparative study of these forms with a group of CHA without lobular inflammation was performed. Both forms of lobular inflammation appeared in young patients, the large majority of whom were infected with the hepatitis B virus; in 5 cases of CHA with lobular hepatitis the presence of the delta agent in the liver, possibly responsible of the lobular inflammation, was detected. The two forms of lobular hepatitis are differentiated by: the fivefold increase of ALAT over the normal value, with usually normal gamma-globulins and albumin, in the first group; in the lobular hepatitis, HBsAg was present in 33% of cases in the first group and in none of the patients of the second group, suggesting the integration of HBsAg within the hepatocytic genome; the clinical picture was generally asymptomatic in the first group and noisier, with hepatomegaly, in the second group; the period elapsed since the acute hepatitis was shorter in the first group (4-11 months) in 8 of 15 patients and longer in the second group. The clinical course of these forms of hepatitis if unforeseeable and the diagnosis is established on the basis of the morphological examination.

[108 cases of hepatic hydatid cyst].

The paper reports on 108 cases of hepatic hydatidosis, admitted to the clinic in the last 12 years, who wer subjected systematically to hepatic imagery, immunologic investigation at hydatic antigen, determination of eosinophil and hepatic biochemical exploration. All the cases were checked operatively. The females were predominant, 66.11%, the average age was of 42.88 +/- 11.94 years. The greatest part of the cases ranged within the 5th-7th age decades. The investigation shows that there exists, in Romania, an endemic region infested with Echinococcus tenia in the Danube zone. The most frequent contamination sources were the cats and dogs; only in 11.11% of the cases the patients were breeding animals. The most cases were discovered late and had an important hepatomegaly. The patients sought help from the physician an ailment in the right hypochondria in 52.78% of the cases, followed by fever (16.68%), biliary colic (12.96%), abdominal pain; (9.26%) and incidentally in 12.04% of the cases. The medium diameter of the hydatic cyst at its discovery was of 10.65% +/- 5.84/14.06 +/- 7.12 cm; only in 21.3% of the cases the diameter of the cyst was lower than 6 cm. The causes of the late diagnosis were: sporadic hepatic imagistic exploration; sensibility of scintigraphy was of 87.5% whereas that of echography was of 98% and that of the CT-scanning od 100%; other cause was due to the lack of immunologic tests at hydatic antigen; sensibility of hemagglutination inhibition is of 65% and that of contra-immunoelectrophoresis of 86%. Owing to the late discovery of the disease, a lethal evolution was recorded by rupture of the cyst and peritoneal inundation in a young patient of 29 years old. Hepatic echinococcosis was unilocular in 74.07% of the case, with predominance in the right lobe (67.5%). The complications rate was of 14.83%, with predominance of the suppuration (10.19%). The paper confirms the endemic state of the hydatic disease, in the Danubian zone of Romania and pleads for the necessity of improving the diagnosis by systematic application of the echographic examination and of better immunologic tests in the ambulatory.

Autoantibodies against the basal cell layer: an association with chronic hepatitis B.

The presence of antibodies against the basal cells of squamous epithelium (BCL-Ab) was studied by indirect immunofluorescence in Rumanian and Swedish carriers of hepatitis B surface antigen (HBsAg), in patients with acute viral hepatitis (AVH), chronic liver diseases (CLD), and various other diseases, and in apparently healthy subjects. Titers of BCL-Ab greater than or equal to 40 were found in 8% of 320 HBsAg carriers, in 20% of 292 patients with CLD associated with HBsAg, and in 2% of 816 patients with HBsAg-negative CLD. BCL-Ab were not found in 167 patients with AVH, nor in 1389 patients with various nonhepatic conditions, nor in 344 apparently healthy subjects. These data indicate an association of BCL-Ab with CLD predominantly of hepatitis B etiology. Possibly hepatitis B virus may induce a form of liver metaplasia with the expression of an antigen with a specificity in common with the regenerative layer of basal cells in the squamous epithelium.

Anti-albumin antibodies in chronic liver diseases: diagnostic significance of these antibodies in patients with conventional or immunosuppressive therapy.

The two categories of anti-albumin antibodies (AAA), namely precipitins (AA-P) and agglutinins (AA-Aggl), were investigated in 260 patients with morphologically diagnosed chronic liver diseases (CLD). A parallelism was observed between AA-P titre and the severity of chronic hepatitis as revealed by clinical diagnosis. Thus, significant differences in AA-P titre were noticed between chronic persistent hepatitis (CPH) and chronic aggressive hepatitis (CAH) and between CAH and liver cirrhosis (LC). No correlation was found between AA-P positivity and either HBsAg presence or disease activity, maximum AA-P values being registered in decompensated, inactive LC. AA-P positivity was found associated with a higher degree of liver cell dysfunction. In every category of CLD a striking association was also observed between AA-P positivity and raised serum aspartate transaminase and bilirubin levels, thus suggesting a common pathogenic substrate, namely liver cell membrane damage. These correlations were also observed after immunosuppressive therapy which would argue for the maintenance of AA-P diagnostic value. AA-Aggl showed raised incidences and titres in CAH patients, the values decreasing in LC. Therefore, the main diagnostic value is attributed to AA-P.
