A number of clinical, biochemical, immunological and morphological variables were recorded at first admission of 500 consecutive patients with biopsy verified acute viral hepatitis in the period February 1969-June 1972. In February 1973, 28 of these patients had a morphologically documented chronic liver disease: 4 cirrhosis of the liver, 15 chronic aggressive hepatitis, and 9 chronic persistent hepatitis. 74 patients were followed up until morphological normalization took place. The initially recorded variables in the two groups were compared, and the following factors were significantly higher in the group with subsequent development of chronic liver disease:--frequency of drug addicts, median of the highest gammaglobulin, ANA, SMA, partial destruction of the limiting membrane, incidence of piecemeal necrosis, and pronounced plasma cell infiltration in the portal tracts. These preliminary results suggest that factors in the initial phase of acute viral hepatitis can be helpful to some extent in predicting the course and prognosis of the disease.

A 16-year-old girl with myocarditis and hepatitis in the course of mycoplasma pneumoniae infection was reported. She had fever and coughed for ten days prior to admission. At the time of admission infiltrations of the left lower lung field were revealed on the chest X-ray films. The ESR was elevated and CRP+6. There were no leukocytosis and anemia, but S-GOT, S-GPT and LDH were moderately increased. On the 11th day of admission VPC in bigeminy appeared and the third sound was heard. Subsequently biphastic and inverted T waves in leads V2 and V3 and flattening of T waves in leads II and aVF appeared. At the same time, the cardiac shadow was enlarged. Antibody titer to mycoplasma pneumoniae increased to more than 1:640 two weeks after admission and then it decreased gradually. The cold agglutinin test was 1:64 on the 8th day of the disease and then it became normal. ASO, antibodies to DNA and immunoglobulins were normal; ANA, Coombs test and LE test were negative. The abnormal ECG-findings were normalized three months later.

Monomeric IgM could be found rather frequently in acute hepatitis and chronic aggressive hepatitis and occasionally also in chronic persistent hepatitis. Earlier it was reported in lympho-proliferative-, autoimmune diseases, some infectious diseases and in cirrhosis of the liver. The occurence of monomeric IgM in chronic aggressive hepatitis correlates with the detection of several autoantibodies (ANA, SMA, RF). The 7S-IgM-test may be used as an easily measurable additional criterium for diagnosis and course of chronic liver diseases.

In chronic active hepatitis (CAH, n=58) 70% of the HBsAg negative and 48% of the HBsAg positive cases showed a CMI against human liver specific proteins (HLPI). Using HBsAg as antigen only 12% of the HBsAg negative and 24% of the HBsAg positive cases gave a CMI response. On the basis of HBsAg and autoantibodies in the serum CAH patients could be divided into 4 subgroups. A close correlation between CMI against HLPI, sex, ANA and HL-A-8 could be detected. In a follow-up study of patients with acute virus B hepatitis (n=62) CMI against HBsAg was detected in 60% of the cases in the acute phase of the disease but in 15% only 3-6 months after the onset of the illness (n=40). In patients who developed a chronic HBsAg carrier status 3 of 5 cases remained persistently positive with HLPI as antigen in the migration inhibition test. - In non-hepatic diseases in which immunological abnormalities may be present (malignant diseases n=46, diabetes mellitus n=27, active tuberculosis, n=18 and untreated systemic lupus erythematodes, n=5) only 26% of patients with malignant diseases showed a migration inhibition with HLPI. - Using different antigens such as human liver specific proteins (HLP), rabbit liver specific proteins (RLP), brucella suis antigen and tuberculin it was possible to demonstrate the validity of the two-step migration inhibition test to detect CMI. The results with different antigens in hepatic and non-hepatic diseases demonstrated that cell-mediated immunity of HLPI is an organ specific immune reaction which is associated with acute and chronic active liver diseases as a time limited or long-lasting phenomenon. Positive reactions in some tumor patients suggest that different mechanisms may elicit an autoimmune reaction against liver antigens.

Bilateral symmetrical polyarthritis occurred in three patients (2 males and 1 female), with no previous history of inflammatory rheumatologic disease, given alpha-interferon for 1 1/2, 7, and 10 months as treatment of chronic non A-non B hepatitis, myelofibrosis, and thrombocytopenia with myeloproliferative disorder, respectively. Joint manifestations developed 1 1/2, 3, and 10 months after initiation of alpha-interferon in a dosage of 3.10(6) U three times a week, 4.5.10(6) U per day, and 8.10(6) U three times a week. Polyarthritis persisted following withdrawal of alpha-interferon in the two last patients of whom one had rheumatoid nodules and positive rheumatoid serology and the other had scleritis, exanthema, and negative rheumatoid serology. Erosive rheumatoid arthritis was diagnosed after 28 months and 12 months, respectively, in two patients who required systemic corticosteroids with antimalarials (1 case) or azathioprine after failure of methotrexate (one case). Follow-up in the third case (12 months) is too short to allow differentiation of systemic lupus erythematosus (ANA: 1/1500 H with anti-DNA antibodies 58 U/ml) and chronic autoimmune hepatitis. Reports of chronic inflammatory rheumatologic disease during alpha interferon therapy are exceedingly few in number. In the cases reported herein, alpha-interferon may have either triggered or revealed the joint disease. To prevent occurrence of this complication, exclusion from alpha-interferon therapy of patients with autoantibodies or a positive history for clinical evidence of immune dysfunction may be considered.

Spectrum, dynamics, and immunoglobulin class of the non-organ specific autoantibodies were investigated in 646 sequential sera from 18 woodchucks with experimental woodchuck hepatitis virus (WHV) infection and in 8 naturally infected chronic carriers of the virus. Among examined WHV carriers, 8 animals developed hepatocellular carcinoma. The sera were tested by indirect immunofluorescence for autoantibodies against smooth muscle (SMA), nuclei (ANA), brush border of proximal renal tubuli (ABBA), and mitochondria (AMA). Analysis revealed that inoculation with WHV was followed by the appearance and/or meaningful elevation of the titre of SMA in IgG class. In all 18 experimentally infected woodchucks, the autoantibody rise preceded the appearance of viral serologic markers (WHsAg and/or WHeAg) by 1 to 4 weeks (mean +/- SD = 2.5 +/- 1.5 weeks). Once induced, SMA remained steadily detectable achieving the peak titre value around week 12 postinoculation. The SMA dynamics did not parallel with the fluctuation of the virus serologic markers and they were similar both in animals who recovered from acute episodes and in those who progressed to chronic infection. In chronic carriers, contrasted to acute infection, fluctuation of SMA titre even to undetectable levels and frequent parallel rises and falls of SMA, ANA, and ABBA titres were observed. A different pattern was found in all three chronic carriers who acquired infection from mothers. In this group, high and relatively stable autoantibody levels were detected. Development of hepatocellular carcinoma was not associated with any specific autoantibody pattern. This study revealed that WHV invasion undoubtedly induces non-organ specific autoimmune response.(ABSTRACT TRUNCATED AT 250 WORDS)

The concept of auto-immune hepatitis as a disease entity evolved from the descriptions of 'chronic active hepatitis' (CAH) in the 1950s. Several types of CAH are distinguished by disease-specific features. The distinctive (but not exclusive) markers for auto-immune CAH include: a negative test for HBsAg; female; Northern European ethnic background; multisystem disease expression; histological CAH with large areas of periportal piecemeal necrosis and plasmacytosis; pronounced hypergammaglobulinaemia; serum auto-antibodies the HLA B8-DR3 phenotype; responsiveness to corticosteroid therapy; and rarity of supervening hepatocellular carcinoma. Much weight is attached to the serological marker auto-antibodies to nuclear or smooth muscle (actin) antigens (ANA, SMA). However, these auto-antibodies do not have an absolute association with auto-immune CAH: the serological reactions are not yet standardized; titres decrease with remission of disease; and other auto-antibodies mark variant forms of auto-immune hepatitis. A more confident acceptance of auto-immune hepatitis as an entity requires detection of a liver-specific antigen, a valid experimental disease model in animals, and a better understanding of immune-mediated damage to liver cells.

Eighty eight patients of glomerulonephropathies (HBsAg positive 67; HBsAg negative 21) and 88 matched and healthy controls were screened for non-organ specific autoantibodies-ANA, AMA, ASMA and APCA by indirect immunofluorescent technique. The 2.3 per cent positivity in the test group and the 8 per cent positivity in the control group did not suggest the involvement of hepatitis-B virus (HBV), as an influencing or associated agent. When 48 patients with glomerulonephropathies and 23 controls were screened for liver cell membrane (LMA) and renal cell membrane antibodies (RMA) by indirect immunofluorescent technique using isolated rat hepatocytes and renal cells, 79.2 per cent LMA positivity was seen in the HBsAg positive group and 41.7 per cent in the negative group and RMA positivity was 58 per cent in the positive group and 25 per cent in the negative group. Simultaneous positivity for both LMA and RMA was recorded in 50 per cent of the HBsAg positive patients and 15.7 per cent of the negative ones. The results suggest the possibility of an organ specific autoimmune trigger more frequently in HBV associated glomerulonephropathy.

We retrospectively studied 94 children with urticaria longer than six weeks in duration. The disease was equally distributed among the sexes and the following age subgroups (0-3.9 years, 4.0-7.9 years, 8.0-11.9 years and 12.0-15.9 years). A cause of the urticaria was identified or suspected in 15 of the patients. These included eight patients with cold urticaria, two with infection (hepatitis, sinusitis), two with food allergy, one patient with juvenile rheumatoid arthritis, one with arthralgia associated with a positive ANA and one with a low level of total hemolytic complement (CH50). Follow-up of a year of more on 52 patients revealed a median duration of urticarial symptoms of 16.0 months, with 58% of children becoming symptom free for six months or more, whereas the remaining 42% continued to have recurrent symptoms but without the development of an underlying serious illness. Results of the present study indicate that the etiology of chronic urticaria in childhood remains mostly undetermined but that the prognosis is generally favorable. However, one must consider an underlying infection or autoimmune disease as a potential etiology.

To clarify the importance of ethnic and geographic factors in chronic active hepatitis (CAH), HBV markers and autoantibodies (AMA, ANA, SMA), have been compared in 158 patients with biopsy-proven CAH from New York City and in 92 patients with CAH from Milan. HBsAg-positive CAH was more frequently observed in Milan (49%) than in New York City (27%). However, among HBsAg-positive patients, HBcAg, HBeAg, and epidemiologic risk factors for acquisition of HBV infection were more frequently found in New York than in Italy. The prevalence of HBsAg-negative, anti-HBc-positive CAH and cryptogenic CAH was similar in the two cities, while autoimmune CAH was more frequently observed in New York (20%) than in Milan (2%). In particular, the prevalence of autoimmune hepatitis was higher among Jewish patients than among patients of Anglo-Saxon or Latin ethnic background in New York. Thus, environmental and/or ethnic factors may influence the prevalence of the four major types of CAH.
