Eight cases of feline pancreatic adenocarcinoma and two cases of pancreatic adenoma were reviewed. The adenomas were incidental findings. Most cats with adenocarcinomas had anorexia (75%) and vomiting (63%), while 38% had abdominal pain, a palpable abdominal mass, and/or jaundice. Diagnostic abnormalities included leukocytosis, hyperglycemia, increased alanine aminotransferase activity, poor serosal detail on abdominal radiography, and an abdominal mass effect on ultrasonography. The majority of cats with carcinomas had metastases (mostly to liver, lung, and small intestine), and all were euthanized or died within 7 days of diagnosis. Clinically, feline pancreatic carcinoma may be difficult to distinguish from feline pancreatitis.

A study in healthy men and women was performed to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of orally administered recombinant human interleukin-11 (oprelvekin) (OAO). Four cohorts of 10 subjects each received 3, 5, 10 or 30 mg (8:2/OAO:placebo ratio), first as a single dose with a 7-day washout period, then 7 consecutive daily doses. Safety was assessed by ongoing evaluation of adverse events (AEs) and laboratory values. PK samples were collected on the first and last day of dose administration. The established effects of subcutaneous oprelvekin on C-reactive protein (CRP, upward arrow), platelet count (upward arrow), fibrinogen (upward arrow) and hemoglobin (downward arrow), were evaluated. PK analysis showed that most subjects (27/34, 79%) had undetectable serum levels of IL-11. PD measures showed no changes from baseline between any OAO group and the placebo group. Orally administered oprelvekin was safe and well tolerated at all doses. A total of five AEs (abdominal pain, diarrhea, headache, rhinitis, grade 3 alanine aminotransferase elevation) were reported across all groups. Evaluations of serum IL-11 levels indicate that OAO is not systemically absorbed at levels above the lower limit of the bioanalytic assay. These data in addition to the lack of effect on PD measures suggest that there is a decreased potential of systemic adverse events with OAO.

Childhood NAFLD has become an important childhood liver disease, and it is probably highly prevalent. The full of spectrum of NAFLD has been identified in children. It is not currently known whether or not simple hepatic steatosis in children is benign or whether it evolves to NASH over time. In contrast, childhood NASH certainly can have serious consequences. Cirrhosis is apparently rare in children with NAFLD, but it definitely occurs. Childhood NAFLD may occur in very young children, and there is no female predominance in the pediatric age bracket. Children present with vague abdominal pain, if they have any symptoms at all, but frequently hepatic steatosis is found incidentally on abdominal imaging. Laboratory studies show that serum aminotransferase abnormalities are rather moderate, with serum alanine aminotransferase (ALT) more elevated than serum aspartate aminotransferase (AST). Hypertriglyceridemia is the typical blood lipid abnormality, although hypercholesterolemia may occur. NASH may be more severe in children from certain ethnic groups, including Hispanics and Asians, or in association with certain metabolic disorders characterized by abnormalities in insulin receptor structure or signaling, such as lipodystrophy syndromes. Weight loss through dietary redesign and a regimen of regular exercise remains the mainstay for treatment for childhood NAFLD. A dietary strategy to minimize postprandial hyperinsulinemia and overall fat intake, such as a low glycemic index diet, may be the best dietary strategy. The real efficacy of drug treatments in children requires further investigation. The overriding message is that childhood obesity poses important health problems, including but not limited to potentially severe chronic liver disease. Early diagnosis of children who are only overweight is a worthy goal so that strategies to limit obesity can be instituted as early as possible. Identification of genetic risks is important, but management will invariably require changes in environmental factors. In addition to individual treatment, a multifaceted, societal initiative is required for solving the childhood obesity epidemic.

We present the case of a patient with chronic hepatitis B who developed an extensive intrahepatic hematoma, associated with a 30-fold elevation in serum alanine aminotransferase levels, following percutaneous liver biopsy. The patient was hypertensive but without hemorrhagic diathesis by routing tests done before biopsy. There was no concomitant intraperitoneal hemorrhage and no blood transfusions were required, despite a 9% drop in hematocrit. The complication was associated with short-lived, mild-to-moderate abdominal pain, easily relieved by paracetamol analgesics. The intrahepatic hematoma, as followed by computed tomography, resolved within 8 months. This case indicates that extensive intrahepatic hematoma and associated ischemic injury may infrequently complicate a liver biopsy and that hypertension may be a predisposing factor.

Bacterial infections are a serious complication of end-stage liver disease (ESLD) that occurs in 20% to 60% of patients. We retrospectively reviewed medical records of patients with ESLD who were identified by our microbiology laboratory as having Streptococcus salivarius bacteremia. Of 592 patients listed for transplantation between January 1998 and January 2006, 9 (1.5%) had 10 episodes of S salivarius bacteremia. Of 2 patients already receiving quinolone prophylaxis for spontaneous bacterial peritonitis (SBP), 1 later presented with a second episode. The male-to-female ratio was 1:1.2. Medians for age, Model for End-Stage Liver Disease score, and Child-Turcotte-Pugh score were 50 years, 17, and 10, respectively. Presenting symptoms and signs in 10 episodes of infection were ascites (in 8 episodes), elevated temperature (6), abdominal pain (5), and encephalopathy (4). Median laboratory values included: white blood cell count, 15.1 x 10(9)/L; creatinine, 0.9 mg/dL; albumin, 3.1 gm/dL; aspartate aminotransferase, 64 U/L; alanine aminotransferase, 52.5 U/L; ammonia, 67 mug/dL; and prothrombin time, 17.3 seconds. Ascitic fluid in patients with peritonitis showed a median white blood cell count of 466 cells/mm(3) (range, 250-12,822 cells/mm(3)), with 66% polymorphs, protein of 0.9 gm/dL, and albumin of 0.4 gm/dL. S salivarius may cause primary bacteremia and SBP in liver transplantation candidates despite quinolone prophylaxis.

Acute intermittent porphyria is an autosomal dominant inherited disorder resulting from a deficiency of porphobilinogen deaminase activity, the third enzyme in the heme biosynthesis pathway. This disease is uncommon, although the prevalence is higher in asymptomatic heterozygotic carriers; however, this prevalence is difficult to establish because of the absence of symptoms. Although acute intermittent porphyria is a multisystemic disease, its most common form of presentation is abdominal pain and neurological or mental symptoms, which can sometimes be due to precipitating factors such as reduced energy intake, smoking, alcohol, some drugs, and stress. Diagnosis can be made by testing urinary porphobilinogen levels, with subsequent measurement of enzyme activity and DNA testing. Treatment is based on prevention of porphyria attacks by avoiding precipitating factors and early administration of intravenous glucose or hemin therapy. We present the case of a patient diagnosed with acute intermittent porphyria based on study of chronic mild alanine aminotransferase (ALT) elevation.

Spontaneous intrahepatic bleeding is a rare condition. In the absence of trauma, intrahepatic hematoma may be due to underlying liver disease. We report a case of hepatocellular carcinoma in the patient who had huge intrahepatic hematoma without definite intrahepatic tumor at the time of initial presentation. A 54-year-old man was admitted to our hospital with a sudden onset of upper abdominal pain. Initial abdominal CT scan showed huge hematoma measuring more than 13 cm in diameter in the right lobe of the liver. However, there was no enhancing lesion in the liver. Laboratory data showed high alanine aminotransferase, alpha-fetoprotein and positive HBsAg. The MRI and angiography could not also depict any mass in the liver. The patient was treated with percutaneous drainage on the intrahepatic hematoma. The cytology from drainaged blood revealed no malignant cell. After hematoma decreased, follow-up CT scan depicted an enhancing tumor in the liver. He underwent right hepatic lobectomy and histopathological examination showed hepatocellular carcinoma.

Abstract Bicalutamide is a nonsteroidal antiandrogen used extensively during the start of androgen deprivation therapy with a luteinizing hormone-releasing hormone agonist to reduce occurrence of the symptoms of tumor flare in patients with metastatic prostate carcinoma. The most common adverse effects of bicalutamide are induced by its pharmacologic property of competitive androgen receptor blockade and include gynecomastia, hot flashes, fatigue, and decreased libido. Although not as common, increases in liver function test results are also seen with bicalutamide therapy. These elevations are typically transient, and patients remain asymptomatic. We describe a 59-year-old man with metastatic prostate carcinoma treated with bicalutamide as part of androgen deprivation therapy before starting chemotherapy. At baseline, his liver function test results and serum creatinine concentration were within normal limits, and an abdominal computed tomographic scan did not demonstrate liver metastasis. After 4 days of bicalutamide therapy, the patient came to the emergency department with complaints of abdominal pain, distension, and tenderness. His liver function tests were abnormal, and bicalutamide was discontinued. After 2 days of increasing liver function tests and symptoms of hepatotoxicity, the patient developed tachycardia and hypotension that was resistant to fluid resuscitation. Multiorgan damage was manifested by an alanine aminotransferase level greater than 40 times the upper limit of normal, serum creatinine concentration of 4.2 mg/dl, and troponin I level of 18 ng/ml. The patient died 8 days after bicalutamide therapy was begun secondary to multiorgan failure, most likely as a result of fulminant hepatotoxicity. The Naranjo adverse drug reaction probability scale showed a probable (score of 5) causal relationship between bicalutamide and fulminant hepatotoxicity. Fulminant hepatotoxicity is a rare but potentially fatal adverse effect of bicalutamide. Liver function tests should be monitored before and during bicalutamide therapy, even for patients who have previously completed a course of this therapy with no signs or symptoms of toxicity.

A 53-year-old male patient was admitted to our hospital with abdominal pain in the right upper quadrant. There was no change in laboratory investigations other than a slight increase in serum levels of alkaline phosphatase (ALP), alanine aminotransferase (ALT), and gamma glutamyl transferase (GGT). Computed tomography (CT) of the abdomen showed multiple hepatic nodular lesions in the liver. Tru-cut biopsy of the lesions was reported as well-differentiated neuroendocrine carcinoma. The patient received sandostatin treatment. After a few days, the patient was hospitalized in the intensive care unit with disturbance of consciousness and clinical features suggestive of encephalopathy. Serum ammonia level was found highly elevated. After the treatment with L-ornithine-L-aspartate, a remarkable improvement in the level of patient's sensorium occurred as well as a reduction in serum ammonia level within a few days. Transarterial chemoembolization (TACE) was performed one week later. The patient's condition began to worsen along with increase in serum ammonia level and he died because of hyperammonemic encephalopathy. There are case reports of hyperammonemia with some malignancies such as multiple myeloma, plasma cell leukemia, and leiomyosarcoma, or in some patients who have received chemotherapy. This case may suggest an association between hyperammonemia and neuroendocrine tumors.

OBJECTIVE: This study was designed to investigate the pharmacokinetic effects of coadministration of saquinavir/ritonavir with efavirenz at steady state. METHODS: Healthy volunteers in this open-label, two-arm, one-sequence, two-period crossover study (planned enrollment of 40 participants) were randomized to one of two treatment arms: those in Arm 1 were scheduled to receive saquinavir/ritonavir 1,000/100 mg orally twice daily for 29 days and efavirenz 600 mg orally once daily starting on day 15 and continuing through day 29; participants randomized to Arm 2 were to receive efavirenz once daily for 29 days and saquinavir/ritonavir 1,000/100 mg twice daily starting on day 15 through day 29. Assessments included vital signs, laboratory analyses, electrocardiography, and blood levels of total saquinavir, ritonavir, and efavirenz. Pharmacokinetic parameters included C(max) (maximum observed plasma concentration), t(max) (time to reach the maximum observed plasma concentration), (apparent elimination half-life), and AUC(0-tau) (area-under-the-plasma-concentration-time curve over one dosing interval). RESULTS: Eight participants (four in each arm) were enrolled; only two (one from each treatment arm) reached day 15 of the study and received the concurrent initial doses of saquinavir/ritonavir and efavirenz. The study was terminated prematurely after these two participants experienced nonserious adverse events. The participant in Arm 1 experienced mild abdominal discomfort, diarrhea, sleep disorder, and headache and the participant in Arm 2 experienced moderate-intensity abdominal pain and mild vomiting with leukocytosis accompanied by elevated pancreatic and hepatic enzymes (aspartate aminotransferase and alanine aminotransferase values of 2-fold and 3.5-fold the upper limit of normal, respectively). Both participants recovered completely following treatment discontinuation. Only limited pharmacokinetic data were generated on these two participants. CONCLUSIONS: The early termination of this study precluded drawing any definitive conclusions regarding the pharmacokinetics at steady state of coadministered saquinavir/ritonavir and efavirenz.
