[Tienilic acid-induced hepatitis associated with liver/kidney microsomal antibody (author's transl)].

Six patients developed acute, subacute or chronic hepatitis after taking tielinic acid, a new diuretic used in the treatment of hypertension. Two died of acute liver failure. The condition was characterized by marked increase in serum transaminases, parenchymal necrosis and portal and/or lobular inflammatory fibrosis. In addition, the serum of all patients contained high titers of a liver/kidney microsomal antibody, which disappeared either after tienilic acid was discontinued or after prednisolone was introduced. The study shows that tienilic acid may be responsible for acute or chronic hepatitis and suggests that a liver/kidney microsomal antibody could be a sero-immunological marker of drug-induced liver disease.

[Pulmonary emphysema, hepatic lesions, and insulin-dependent diabetes in a patient with alpha-1-antitrypsin (Pi ZZ) deficiency (author's transl)].

A 47-year-old patient with panlobular emphysema and insulin-dependent diabetes had an alpha-1-antitrypsin phenotype Pi ZZ deficiency. Liver function tests were abnormal, and postmortem examination of the liver demonstrated abnormal intrahepatocytic globules of A1AT (a typical finding when the allele Z is present), but also fibrosis with steatosis. The patient's sister, Pi ZZ, had neither diabetes nor bronchopneumopathy, and no anomalies in liver function. Needle puncture biopsy of the liver had not been conducted. The phenotype Pi ZZ is typically associated with panlobular emphysema in adults, and cholestatic hepatitis in children. From reports in the published literature, it appears that isolated hepatic lesions or those associated with emphysema are rare. The fortuitous association of diabetes and hepatic lesions in this typical case of pulmonary affection in an adult is discussed.

[Nephropathy and nodular regenerative hyperplasia of the liver (author's transl)].

A renal biopsy performed on a young woman with proteinuria showed a nephropathy consisting of major interstitial infiltration by lipophages and thickening of the glomerular capillary walls with a large amount of "spikes". Anti-IgG, IgM, C3 and C1q sera bound themselves to the extramembranous deposits and the anti-IgM serum to the endomembranous deposits. This striking finding was associated with a regenerative nodular hyperplasia of the liver, an entity that has been observed in only about 20 cases. An underlying immunological defect was suggested by the continuous presence of a mixed cryoglobulinemia.

[Diffuse polymorphous inclusions in a patient treated with perhexiline maleate (author's transl)].

Case report of polyneuritis and liver dysfunction induced by perhexiline maleate in a 64 years old male patient. The ultrastructural study of nerve, liver, muscle and skin biopsies shows polymorphous, membrane bound, often multilamellar, lysosome-like inclusions, the content of which is probably complex lipids. The histochemical study of liver reveals a lipid storage, consisting mainly of triglycerides and of smaller amount of phospholipids and free fatty acids, the pattern of which is abnormal. The biochemical study of nerve tissue shows a decrease of phospholipids levels and some qualitative disturbances in gangliosides. These changes, some of which are similar to those reported in amphiphilic drug intoxications, are prevalent in high lipid metabolism cells such as hepatic and Schwann cells.
