Incidence and clinical significance of anti-ENA antibodies in systemic lupus erythematosus. Estimation by counterimmunoelectrophoresis.

Eighty-two patients with systemic lupus erythematosus (SLE) were investigated for the presence and significance of serum antibodies to Extractable Nuclear Antigen (ENA) and its major components, RNP, Sm and SS-B (or Ha). The counterimmunoelectrophoresis assay allowed independent detection and measurement of antibodies to the different components. Forty patients had anti-ENA antibodies, 25 (30%) were of anti-RNP type alone or anti-RNP associated with anti-Sm, and 12 (15%) were of anti-RNP type alone. Anti-ENA antibodies distinguished a subset of patients with less common incidence of renal disease, positive Coombs test, anticoagulant serum factors and high titres of anti-DNAds antibodies, with higher incidence of Raynaud's phenomenon, swollen hands, hypergammaglobulinemia and high titres of antinuclear antibodies with speckled pattern on immunofluorescence. SLE patients with anti-RNP antibodies had in addition a high frequency of normal complement values. All but one SLE patient with only anti-RNP antibodies fulfilled at least four or more criteria for the diagnosis of SLE. We conclude that anti-ENA antibodies in SLE patients are associated with a low prevalence of nephritis and a clinical and laboratory profile similar to that of the MCTD syndrome. These findings demonstrate the difficulty of inferring rigid differences between MCTD and SLE. The MCTD syndrome probably represents only one segment of the whole clinical spectrum of SLE.

[Histologic evolution of acute alcoholic hepatitis].

Although acute alcoholic hepatitis is a frequent disease with distinct histologic diagnosis, the prognostic factors of its evolution are largely unknown. The present report analyzes the data of 18 patients with acute alcoholic liver disease submitted to two liver biopsies with a mean interval of 35 months. The results demonstrate a favorable histologic evolution in six of seven patients that abandoned alcohol ingestion, and an evolution to chronic liver disease in the remaining case. Out of six patients with continuous alcohol ingestion the evolution was unfavorable in five, while one case evolved to healing. Centrilobular fibrosis disappeared in the six cases that discontinued alcohol ingestion and who had favorable evolution, and it persisted in four of the six patients that continued drinking. The results suggest that centrilobular fibrosis is not always an unfavorable prognostic marker, and that the evolution of acute alcoholic hepatitis is not exclusively dependent on the continuation of alcohol abuse.

[Granulomatous hepatitis. Etiologic study of 107 cases (author's transl)].

An etiologic study was made of 107 cases of granulomatous hepatitis which were observed in a Department of Internal Medicine between January, 1971 and December, 1977 (excluding the hepatobiliary diseases). The most common etiology was tuberculosis (30 cases, 28 percent) followed by sarcoidosis (19 cases, 17.7 percent), Mediterranean exanthematous fever (13 cases, 12.1 percent), brucellosis (8 cases, 7.4 percent) typhoid fever (7 cases, 6.5 percent) and the idiopathic forms (8 cases, 7.4 percent). A lower rate of incidence was among Hodgkin's disease, toxoplasmosis, adenocarcinomas, leprosy, and those of unknown etiology, classified in this way because the study and follow-up of the patients could not be completed. There were, moreover, individual cases caused by mononucleosis, BCG reaction, hypogammaglobulinemia, celiac disease, and temporal arteritis. From a clinical point of view 50 percent of the patients had hepatomegaly and moderate disturbance of the liver enzymes. The most important enzymatic increases were detected in the cases caused by brucellosis; in the cases which were secondary to sarcoidosis the liver enzymes were normal. A comparison is established between the etiologic incidence of the present series and of others published in the literature. The causes and diagnostic problems of this type of lesion are discussed.
