We report a patient with autoimmune hepatitis, who simultaneously satisfied the 1982 revised ARA criteria for systemic lupus erythematous and emphasize the difficulty in differentiating these two diseases. In addition, current concepts of a possible immunological distinction between autoimmune hepatitis and hepatic involvement in SLE are reviewed.

Sera from 5154 subjects comprising patients with liver diseases (n = 1311), immunological and connective tissue disorders (n = 1098) and other diseases (n = 2421), and healthy people (n = 324), were investigated by immunofluorescence for IgG antibodies (titre greater than or equal to 1:20) against mitochondria (AMA), endoplasmic reticulum (AER), nonorganspecific ribosomes (ARA-1), and liver typical ribosomes (ARA-2). AMA were classified in 10 subtypes. AMA (n = 163 = total 3.2%) were found predominantly in liver diseases (n = 101 = 7.7%) and in autoimmunopathies (n = 34 = 3.1%). AER (n = 59 = total 1.1%) were detected mainly in liver diseases (n = 40 = 3%), ARA-1 (n = 14 = total 3%) in autoimmunopathies (n = 7 = 0.64%), and ARA-2 (n = 7 = total 0.14%) exclusively in liver diseases (n = 7 = 0.5%) (acute and chronic relapsing hepatitis with viral markers). The diagnostic value of antibodies depends among other things on the titre and the subtype. AMA of type 2 and 4 with a titre higher than 1:1280 are a valuable marker of primary biliary cirrhosis or a related disease, even in the absence of other diagnostic signs. AER with a titre higher than 1:320 suggest a special form of autoimmune chronic hepatitis with rapid progress to liver cirrhosis. The diagnostic value of other antimitochondrial antibodies (especially those of type 5 to 10) and of antiribosomal antibodies is not exactly known.

The widespread use of alpha-interferon (IFN-alpha) therapy in different diseases draws attention to its side effects, such as autoimmune-related diseases, especially thyroid autoimmune dysfunctions. Data about hepatitis and nonhematologic neoplasia are available, while data about hematologic malignancies are fragmentary. We studied the incidence of autoimmune-related disturbances and thyroid dysfunctions in 54 consecutive patients suffering from hematologic malignancies, treated with recombinant human IFN-alpha for a mean time of 15.9 +/- 8.9 months. Our results minimize the incidence of autoimmune dysfunctions in hematologic malignancies as side effects of IFN-alpha therapy. We registered the appearance of autoantibodies in only 3 females (5% of total): 2 patients (1 affected with essential thrombocythemia and one with multiple myeloma) presented antithyroglobulin antibodies with no clinical symptoms; 1 patient, affected with essential thrombocythemia, developed antinuclear antibodies with arthralgia and myalgia. ARA criteria for systemic lupus erythematosus were not fulfilled but the therapy had to be interrupted. No patient developed thyroid dysfunction. In patients with hematologic malignancies, the dosage and the duration of IFN-alpha treatment do not seem to influence the appearance of autoantibodies, while female sex appears to be a risk factor.

Central Nervous System involvement in Systemic Lupus Erythematosus (CNS-SLE) is very common and ranges between 25%-70% of the patients. The CNS involvement is listed in the ARA criteria for SLE diagnosis. CNS-SLE is associated with more than 20 different autoantibodies. Yet, remarkable among them are the anti-P-ribosomal antibodies (anti-PR). These autoantibodies directed mainly against the carboxy 22 amino acids of the PO, P1 P2 ribosomal phosphoproteins. They are capable of penetrating lived cells and inducing apoptotic changes as well as leading to inhibition of specific cytokine secretion. The titer of the autoantibodies correlate with disease activity, kidney involvement and hepatitis. In this review, the mechanisms involved in CNS involvement and its relationship with anti-P ribosomal antibodies will be described.
