Diabetes mellitus was tentatively diagnosed in a black-footed ferret with polyuria, polydipsia, polyphagia, dehydration, and weight loss. Laboratory findings (marked hyperglycemia (724 mg/100 ml), glycosuria, and ketonuria) and the subsequent favorable response to insulin therapy confirmed the diagnosis. Although lesions were not observed in the pancreas, gross and histologic findings concomitant with diabetes mellitus included arteriosclerosis, with calcification of the aorta and other major vessels; mild necrotizing hepatitis; and mild proliferative glomerulonephritis. A perineal adenocarcinoma, with metastasis to an internal iliac lymph node, was an incidental finding. Special stains demonstrated adequate numbers of beta cell granules in the islets of Langerhans. Thus, the diabetes was apparently due to a lack of release of the synthesized insulin or to diminished effectiveness of the secreted insulin.

The Southwest Oncology Group studied the response rate and toxicity of didemnin B (3.47 mg/m2 i.v. q 28 days) in patients with advanced renal cell carcinoma. There were no responses in 22 response evaluable patients. Toxicity was significant with 10 patients having grade 3 or 4 toxicity. Toxicity seen included nausea and vomiting, exacerbation of coronary artery disease, hyperglycemia, anorexia, diarrhea and hepatitis. Didemnin B was toxic but inactive in patients with renal cell treated at this dose.

Ischemic hepatitis is not an uncommon complication of reversible severe hypotension or cardiac failure. The prognosis usually is determined by the cause of the initial hypotension or cardiac failure, rather than the subsequent hepatic dysfunction. We report a retrospective analysis of nine patients with ischemic hepatitis in which previously unreported clinical and biochemical abnormalities are noted. The clinical and biochemical course of the patients were reviewed until recovery or death from ischemic hepatitis. All the patients had a rapid striking elevation of aspartate aminotransferase, and lactic dehydrogenase, with an equally rapid resolution of these parameters. Abnormal serum glucose levels occurred in six patients (none of whom had a prior carbohydrate intolerance). Insulin therapy was given to three patients for a limited period. Renal impairment was manifest in all nine patients, and it resolved spontaneously within 10 days. Altered mental status was detected in six patients; the changes reverted to normal within 7 days of their onset. A preexisting anemia (hemoglobin less than 11.0 g/dl) was noted on admission in four patients, and it did not appear to potentiate the manifestations of the hepatic ischemia. We conclude that ischemic hepatitis should be anticipated in all patients with a recent history of systemic hypotension. It should be considered in the differential diagnosis of patients with unexplained hepatitis; the early massive rise in lactic dehydrogenase, the rapid fall in transaminases, and the early mild/moderate renal failure strongly suggest ischemic hepatitis. Patients with ischemic hepatitis can manifest reversible renal failure, mental confusion, and hyperglycemia which may require insulin for its control.

The risk of opportunistic infection in the renal transplant patient is due to an interaction between two major factors: the epidemiologic exposures (particularly within the hospital environment) and the net state of immunosuppression. The net state of immunosuppression is determined by the nature, dose, and duration of the immunosuppressive therapy being administered; the presence or absence of granulocytopenia and technical factors that could compromise the primary mucocutaneous barriers to infection; such metabolic factors as uremia, hyperglycemia, and the state of nutrition; and, finally, the immunomodulating effects of such viruses as CMV, the hepatitis viruses, and HIV. The major types of opportunistic infection to which the renal transplant patient is susceptible are the following: the viruses of the herpes group and papovaviruses; bacteria such as L monocytogenes, N asteroides, and Legionella; such fungi as Candida, Aspergillus, C neoformans, and the Mucoraceae; and protozoans such as P carinii, S stercoralis, and T gondii.

Genetically obese mice (C57BL/6J-ob/ob), fed ad libitum, demonstrated a precipitous increase in the spontaneous death rate after 50 weeks. The first signs of morbidity were a ruffled hair coat and a progressive motor ataxia. Necropsy revealed that obese mice had pale and fatty livers, urolithiasis and grossly distended bladders. Microscopically, the hepatocellular changes observed in all aged obese mice included: a loss of orientation of hepatocytes, an enormous variability in the size of both hepatocytes and their nuclei, and an extensive deposition of both large and small lipid droplets, confirmed by an increase content of triacylglycerols. A subacute-to-chronic, multifocal, necrotizing hepatitis was also present. Kidneys from aged obese mice contained hypertrophied glomeruli and increased PAS-stained material. Tubular dilation with compaction of the tubular cells was also seen. There were no significant alterations in the microanatomy or mineralization of femurs from obese mice, yet there was a significant increase in plasma alkaline phosphatase activity. In obese mice at 62-63 weeks of age, hyperglycemia was present even in spite of hyperinsulinemia. Pituitary immunoreactive ACTH and its molar ratio to pituitary immunoreactive beta-endorphin were also increased in obese mice at this age. Even though the etiology of the decreased lifespan of genetically obese mice remains uncertain, the possibility is discussed that an overall defect in the central nervous system may be involved.

A 60-year-old obese woman with type II diabetes mellitus and hepatomegaly exhibited progression of steatosis to hepatitis and cirrhosis. The patient was treated with large amounts of insulin combined with sulfonylurea, resulting in correction of the hyperglycemia. In the subsequent 9 months, weight loss did not occur, whereas insulin therapy could be discontinued. The liver decreased in size, and liver tests normalized. We suggest that intensive treatment of hyperglycemia may result in reversal of insulin resistance in patients with diabetic liver disease, while correction of hyperglycemia can lead to resolution of the hepatic abnormalities associated with diabetes mellitus.

Coxsackieviral infections have been linked etiologically to multiple diseases. The serotype CB4 is associated with acute pancreatitis and autoimmune type 1 diabetes. To delineate the mechanisms of host survival after an acute infection with CB4 (strain E2), we have investigated the role of nitric oxide (NO), generated by the inducible form of nitric oxide synthase (NOS2), in viral clearance and pancreatic beta-cell maintenance. Mice deficient in NOS2 (NOS2-/- mice) and their wild-type (wt) counterparts were injected with CB4, after which both groups developed severe pancreatitis, hepatitis, and hypoglycemia within 3 days. Within 4 to 7 days postinfection (p.i.), most of the NOS2-/- mice died and at a strikingly higher mortality rate than wt mice. Histological examination of pancreata from both infected NOS2-/- and infected wt mice revealed early and complete destruction of the pancreatic acinar tissue, but intact, insulin-stained islets. When examined up to 8 weeks p.i., neither surviving NOS2-/-mice nor surviving wt mice developed hyperglycemia. However, the clearance of infectious CB4 was different between the mice. The spleens of NOS2-/- survivors were cleared of infectious virus with kinetics similar to that of wt mice, but the livers, pancreata, kidneys, and hearts of the NOS2-/- groups cleared virus more slowly than those of the wt group. This delayed clearance was particularly prominent in the livers of infected NOS2-/- mice, which also showed prolonged histopathological features of viral hepatitis. Taken together, this outcome suggests that NOS2 (and NO) is not required for the prevention of pancreatic beta-cell depletion after CB4 infection. Instead the critical actions of NOS2 apparently occur early in the host immune response, allowing mice to survive and clear virus. Moreover, the data support the existence of an organ-specific dependency on NO for a rapid clearance of CB4.

Two sibs with an infantile onset of hyperglycemia, recurrent hepatitis, renal insufficiency, developmental delay, and skeletal epiphyseal dysplasia are described. Clinical presentation and radiological features are suggestive of Wolcott-Rallison syndrome, a rare autosomal recessive disease. In both of our cases we found evidence of central hypothyroidism, which appears to be an associated feature of this syndrome. Hypothyroidism should be suspected and screened for in all cases of Wolcott-Rallison syndrome.

The levels of dehydroepiandrosterone (DHEA) and its sulfate (DHEA-S) peak in human in their twenties, then decrease gradually with age. The physiological importance of DHEA was not clear until recent research reports showing that DHEA has beneficial effects on preventing diabetes, malignancy, inflammation, osteoporosis, and collagen disease. We summarize our results concerning diabetes, hepatitis, and colon cancer. In 1982, Coleman et al. [Diabetes 31 (1982) 830] reported that DHEA decreased hyperglycemia in diabetic db/db mice, which become insulin resistant. We measured hepatic gluconeogenic enzymes in an attempt to elucidate the mechanical mechanism of DHEA action. The activity and gene expression of hepatic gluconeogenic enzyme such as glucose-6-phosphatase (G6Pase) was increased in db/db mice despite hyperinsulinemia compared to control db/+m mice. DHEA, like troglitazone, decreased these levels in db/db mice. We also showed that DHEA improved the insulin resistance caused by aging or obesity using the glucose clamp technique in another animal model. In humans, the serum DHEA concentration was shown to be associated with hyperinsulinemia in diabetes. It also became clear that DHEA increased insulin secretion in old-aged db/db mice. DHEA increases not only insulin sensitivity due to the effects in the liver and muscle, but also insulin secretion. As an effect of DHEA on T-cell mediated hepatitis induced by concanavalin A (ConA), DHEA reduced hepatic injury by inhibiting several inflammatory mediators and apoptosis. As an effect of DHEA on carcinogenesis, DHEA would be a potential chemopreventative agent against colon cancer because it decreases the number of azoxymethane (AOM) induced aberrant crypt foci, which is a possible precursor to adenoma and cancer in a murine model.Thus, since DHEA has many beneficial effects experimentally, we should consider administration of DHEA in the future, and common mechanisms among these actions of DHEA should be elucidated in further studies.
