Five nonalcoholic diabetic women were clinically and histologically verified as having micronodular cirrhosis. In this series all the patients were over 50 years of age, and showed obesity, hyperglycemia, enlarged liver and mild abnormalities of liver function tests. The histological findings differed from hepatitic cirrhosis. In two patients serial biopsies confirmed development of cirrhosis from centrilobular necrosis.

AO-128 is a potent and structurally novel inhibitor of the intestinal disaccharidases, such as maltase and sucrase. Genetically obese-diabetic mice, KKA(y), were used to examine the acute or long-term effectiveness of this compound. AO-128 decreased a postprandial rise in blood glucose after sucrose solution loading dose-dependently; the ED50 to reduce a delta increment of blood glucose by 50% was 0.22 mg/kg. The intestinal sucrase and maltase activities were suppressed to 7 and 48% of the control levels, respectively, at a dose of 0.21 mg/kg. Four-week-old female KKA(y) mice were kept on a laboratory diet containing 10 or 50 ppm of AO-128 for 12 weeks. The high dose of AO-128 reduced food intake and body weight gain throughout the experimental period. On the other hand, the low dose reduced body weight gain for the first 4 weeks without any effect on food intake. Development of the hyperglycemia and hyperinsulinemia characteristic of KKA(y) mice was moderately prevented by the low dose, and completely by the high dose. Hypertriglyceridemia tended to be suppressed by the AO-128 treatment. The high dose decreased the hemoglobin A1 level and parametrial adipose tissue weight. Hepatomegaly and fatty liver were ameliorated by AO-128 dose-dependently. Nephropathy was ameliorated by the high dose. These findings indicate that AO-128 may be useful for treating human obesity and diabetes.

A 33 year old woman with mental deficiency, retinitis pigmentosa, obesity, and parental consanguinity (heredity) was diagnosed as having Laurence-Moon-Biedl syndrome. She also had diabetes mellitus, slight hepatic dysfunction, and hepatomegaly. Liver biopsy showed perilobular fibrosis and bile duct proliferation with cystic dilatation; these findings are consistent with those of congenital hepatic fibrosis.

A 54-year-old woman with obesity, type II diabetes mellitus, hyperlipidemia, and massive hepatomegaly was found to have severe steatosis and cirrhosis on liver biopsy. Complete evaluation led to the diagnosis of fatty cirrhosis associated with obesity and diabetic mellitus. She underwent four months of fasting with a protein-carbohydrate and vitamin-mineral liquid supplement to control her weight and metabolic abnormalities and to evaluate the effect of this diet on her liver disease. She lost 40 pounds to ideal body weight, normalized her serum glucose and lipids, and decreased total liver height by one third. Liver biopsy at the completion of her diet showed inactive cirrhosis and complete resolution of steatosis. Supplemented fasting with only modest weight loss can safely resolve fatty liver in obese diabetics with nonalcoholic steatosis and cirrhosis. Aggressive dietary approaches to achieve long-term weight loss deserve study in this subgroup of diabetics with unexplained chronic liver disease.

Clinical features and liver biopsy findings were studied in six patients with nonalcoholic steatohepatitis associated with hyalin. A comparative study was made on the ultrastructure of the hyalin in one patient with nonalcoholic steatohepatitis and in one patient with alcoholic hepatitis. The patients, all over 50 years old, comprised two females and one male with steatohepatitis and three females with micronodular cirrhosis. They showed obesity, hepatomegaly, and mild abnormalities on laboratory tests. Three of them showed maturity-onset diabetes. The hyalin was found in the cytoplasm of swollen hepatocytes of the centrilobular or in the peripheral region of nodules and was accompanied by necrosis. Ultrastructurally, the hyalin comprised filamentous structures and vesicular or angular structures resembling disorganized circular or branched rough endoplasmic reticulum. It resembled that found in the liver of patients with alcoholic hepatitis.

Thirteen cats with diabetes mellitus were evaluated. Clinical signs included polydipsia, polyuria, polyphagia, lethargy, and weight loss. Results of physical examination included obesity, hepatomegaly, mild seborrhea sicca, muscle wasting, and dehydration. One cat walked plantigrade and was suspected of having a diabetic neuropathy. Persistent hyperglycemia, glucosuria, high liver enzyme activities, hypercholesterolemia, hyperproteinemia, and low electrolyte concentrations were the common laboratory findings. In 3 cats diabetes mellitus developed after megestrol acetate therapy; 2 of these cats required only temporary insulin treatment. In a 3rd cat, which had no history of receiving diabetogenic drug therapy, remission of diabetes mellitus also was observed. Serum insulin and plasma glucose concentrations were determined in 6 cats after administration of an intermediate-acting insulin (isophane insulin) and in 3 cats after administration of a long-acting insulin (protamine zinc insulin). The insulin concentration peaked 2 to 6 hours after the injection of intermediate-acting insulin and 6 to 12 hours after the injection of long-acting insulin. The lowest glucose concentration was recorded 4 to 8 hours after injection of intermediate-acting insulin, and 6 to 12 hours after injection of long-acting insulin. It was concluded that, although insulin therapy must be adjusted to the individual, the diabetic cat usually requires twice-daily administration of isophane insulin; however, the protamine zinc insulin can be given once daily for satisfactory control.

A 40-year-old man was diagnosed as fatty liver according to our ultrasonographical criteria for fatty liver, i.e., liver-kidney contrast in the ultrasound mass screening of the liver, biliary tract and pancreas. He lacked any signs or symptoms, nor any known causes of fatty liver, i.e., obesity, diabetes, hyperlipidemia, ingestion of alcohol or drugs. Liver biopsy of this patient revealed fatty change of about 50% of the hepatic lobules. It has been difficult to suspect the presence of latent fatty liver which lacked both the abnormality in the liver function test and hepatomegaly, and even impossible when it lacked any risk factors. In the future as the ultrasonography becomes more generally used as a primary screening examination, "idiopathic latent fatty liver", like this patient, will be more frequently found and this, in turn, will contribute to the progress of the epidemiology and etiology of fatty liver.

Changes in a number of morphological and biochemical parameters were observed in genetically obese Zucker rats and in lean controls between 3 and 58 weeks of age. By 3 weeks, the genetically obese rats had higher proportional (wt/100 g body wt) and absolute amounts of adipose tissue, hyperlipemia affecting all the lipid fractions, and hyperproteinemia compared to lean controls. Obesity, hepatomegaly, high concentrations of hepatic lipids and hyperinsulinemia did not appear until the fifth week. In obese animals, liver lipid concentration reached a maximum at 17 weeks of age and then declined. During this time, the triacylglycerol concentration in the serum remained stable, whereas the cholesterol and phospholipid concentrations continued to increase. The glycogen concentration in obese animals increased, both absolutely and compared to lean controls, between the 12th and 43rd weeks of age. From weaning, the Zucker rats, compared to lean controls, exhibited characteristics of obesity (accumulation of adipose tissue, hyperlipemia and hyperproteinemia), which persisted to the age of 58 weeks.

A girl presented with small stature, obesity, tapetoretinal degeneration, deafness, psychomotor regression, seizures, acanthosis nigricans, hepatomegaly, and chronic tubulointerstitial nephropathy. She died at age ten with renal insufficiency and uncontrolled seizures. Histochemistry showed lipid storage in hepatocytes, histiocytes, smooth muscles and, to a much lesser extent, kidney tubules and cortical neurons. The liver had increased cholesterol esters (5-fold) and triacylglycerols (8-fold), and decreased phospholipids (50%). Methyllumbelliferyl-oleate, oleylcholestrol, trioleylglycerol, and tripalmitylglycerol lipase activities were markedly reduced in the liver, in the range found in Wolman's disease. In cirrhotic fatty livers these activities ranged from 7-87% of the normal mean. The patient's brain had limited neutral lipid storage and normal methyllumbelliferyl-oleate lipase. Trioleylglycerol lipase activity was 14-60% of controls; tripalmitylglycerol lipase activity 14-25% of controls; and oleylcholestrol lipase activity 12-33% of controls.

Nonalcoholic steatohepatitis is a poorly understood and hitherto unnamed liver disease that histologically mimics alcoholic hepatitis and that also may progress to cirrhosis. Described here are findings in 20 patients with nonalcoholic steatohepatitis of unknown cause. The biopsy specimens were characterized by the presence of striking fatty changes with evidence of lobular hepatitis, focal necroses with mixed inflammatory infiltrates, and, in most instances, Mallory bodies; Evidence of fibrosis was found in most specimens, and cirrhosis was diagnosed in biopsy tissue from three patients. The disease was more common in women. Most patients were moderately obese, and many had obesity-associated diseases, such as diabetes mellitus and cholelithiasis. Presence of hepatomegaly and mild abnormalities of liver function were common clinical findings. Currently, we know of no effective therapy.
