Miltefosine (2.5 mg/kg/day for 28 days) was investigated for treatment of New World cutaneous leishmaniasis in Colombia and Guatemala. The data from a controlled study was remarkably similar to the data of a prior uncontrolled pilot study. In the controlled study, the per-protocol 6-month cure rate for Leishmania panamensis disease was 91% compared with a concomitant placebo cure rate of 38%. In Guatemala, the cure rate for L. braziliensis and L. mexicana disease was approximately 50% compared with approximately 20% for placebo. In both countries, nausea but not 'motion sickness' and vomiting but not diarrhoea were experienced by approximately 30% more miltefosine patients than placebo patients. Mild elevation of creatinine, but not of aspartate aminotransferase or alanine aminotransferase, was also more frequently seen in the miltefosine group than in the placebo group. Miltefosine was well tolerated, and as effective as historic values of antimony for treatment of L. panamensis disease.

Steers and bulls under feedlot conditions and on an apparently adequate ration developed transitory signs of diarrhea and unthriftiness. One animal became recumbent. Sick and clinically normal animals in the group had elevated serum creatine kinase and aspartate aminotransferase enzyme values and degenerative changes in muscle fibers on biopsy. Feed analysis was carried out and the animals were monitored over several weeks by means of muscle biopsy and serum enzyme analysis as well as by postmortem examination at slaughter. Subclinical myopathy was found in several animals and was thought to be related to low vitamin E content in the high moisture corn ration.

Rotavirus is one of the leading causes of acute gastroenteritis among children. While clinical complaints are generally intestinal including vomiting and diarrhea, there is evidence to suggest that disease outside the gastrointestinal tract occurs. This study examines the frequency of hepatic transaminase elevation in children with rotavirus gastroenteritis. Patients identified with rotavirus gastroenteritis by stool antigen testing between November 2005 and March 2006 had available serum analyzed for alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, total bilirubin, direct bilirubin, and creatinine phoshosphokinase (CPK). Chart review was conducted to identify patients with possible liver injury unrelated to rotavirus. Among the 92 patients identified with rotavirus during the study period, 75 had serum specimens available for testing. Fifteen patients (20%) had elevated ALT and AST, including one patient with an increase in AST, ALT, alkaline phosphatase, and total and direct bilirubin. The mean ALT elevation was 56 IU/L (range, 44 to 114 IU/L), and the mean AST elevation was 80 IU/L (range, 57 to 126 IU/L). Fifty-three patients (71%) had an increase in AST alone, and three patients (4%) had an increase in AST and alkaline phosphatase. The mean AST values in these groups were 61 IU/L (range, 42 to 110 IU/L) and 79 IU/L (range, 59 to 96 IU/L), respectively. In conclusion, rotavirus commonly causes elevation of liver transaminases.

Explosives and their breakdown products are commonly found in soils at U.S. military installations. Many areas where these compounds are found represent useful habitat for ground-foraging birds. Because these birds likely are exposed to such compounds, we evaluated the oral toxicity of 2,6-dinitrotoluene (DNT) in a representative ground-foraging species of management concern. Adult male and female northern bobwhite (Colinus virginianus) were exposed to either 0, 5, 10, 40, or 60 mg/kg/d via gavage for 60 d (subchronic) following determination of the median acute lethal dose (320 mg/kg). Circulating levels of red blood cells and hemoglobin were significantly decreased in a dose-dependent manner; however, levels remained within normal ranges. Plasma concentrations of total protein, albumin, globulin, aspartate aminotransferase, and potassium, sodium, and chlorine ions were significantly decreased, and circulating levels of uric acid were significantly increased. Decreased body weight, enlarged gallbladders, edematous gastrointestinal tracts, pale kidneys, pale and fibrous livers, and loose stools were consistent observations. The effects found in the clinical chemistries taken together with histopathological abnormalities observed in sections of hepatic and renal tissue suggest that the liver and kidneys are major targets for 2,6-DNT. Oral exposures to 2,6-DNT appear to affect northern bobwhite in a manner similar to that of the other main DNT isomer, 2,4-DNT, but in more subtle ways, adversely affecting the gastrointestinal system and leading to diarrhea and, ultimately, emaciation. The lowest-observed-adverse-effect level is 40 mg/ kg/d based on hematological measures, and the no-observed-adverse-effect level is 10 mg/kg/d based on the absence of results indicative of adverse effects.

The seroprevalence of hepatitis A virus (HAV) antibodies is low in young adults in Korea. From May to July 2005, 17 cases of HAV were reported from healthcare workers (HCWs) in a hospital intensive care unit (ICU). We looked for the presence of anti-HAV IgM from all patients in the medical-surgical ICU with elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and screened AST and ALT levels in all HCWs who came into contact with two suspected index cases. Once the outbreak was confirmed, the molecular subtypes of HAV from the blood of HCWs were determined. Index cases and a transmission route were identified, and intervention strategies applied to control the outbreak. The 17 HCW cases included 13 nurses and four doctors aged 22-32 years, who each suffered acute HAV infection during the study period. The possible transmission of HAV was via the faecal-oral route from bedridden patients with diarrhoea. All HCWs were positive for anti-HAV IgM and eight were positive for HAV RNA. Analysis of the VP1-2A region of each isolate showed genotype IA in five strains and co-circulation of genotypes IA and IB in the others. This HAV outbreak highlights the importance of standard infection control precautions within a hospital. Molecular study of patients' blood would be useful for clarifying the epidemiology of a suspicious HAV outbreak in a hospital.

Isopropanol (IPA) is a volatile solvent that is used in many industrial process. The major symptoms of acute isopropanol toxicity include dizziness, incoordination, headache, hypothermia, eye ataxia, irritation of upper respiratory tract and shortness of breath. Vomiting, hematemesis, diarrhoea and hypotension may occur following accidental ingestion of IPA. No data regarding subchronic or chronic toxicity of IPA were identified. The aim of this study was to measure the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and of gamma-glutamyltransferase (gamma-GT) of the last five years in 40 printer workers after the removal of IPA from the industry. The serum levels of ALT, AST and gamma-GT were higher in the exposed workers than in non exposed. In conclusion, the results of this study show that the removal of IPA from the industry had a positive health effect improving the hepatic function of the workers.

Drug-induced hepatotoxicity is an infrequent but life-threatening complication. Sunitinib is a multitargeted receptor tyrosine kinase inhibitor approved for treatment of renal cell carcinoma and gastrointestinal stromal tumor. However, results from preapproval clinical trials suggest an equivocal hepatic risk profile for sunitinib. We describe a 75-year-old woman with renal cell carcinoma who was admitted to the intensive care unit after experiencing fulminant hepatic failure during sunitinib therapy. The patient's hepatic and renal chemistries had been within normal limits throughout four previous cycles of sunitinib therapy spanning 9 months. After the fifth cycle, she complained of a 3-day history of severe diarrhea and dehydration. Her abnormal laboratory test results included the following: total bilirubin level 5.9 mg/dl, aspartate aminotransferase level 3872 U/L, alanine aminotransferase level 3332 U/L, ammonia level 897 microg/dl, and an international normalized ratio of 4.8. Use of the Naranjo adverse drug reaction probability scale indicated a possible relationship between sunitinib and hepatotoxicity. Supportive care including aggressive intravenous hydration and reversal of coagulopathy was successful. The patient was discharged home on hospital day 7 without apparent longstanding sequelae. Clinicians should be aware of this possible adverse effect of sunitinib, and continued pharmacovigilance is imperative to accurately quantify the possible risk of sunitinib-related hepatotoxicity.

Revision surgery for loosened hip prostheses is a heavy burden for elderly patients with comorbidity. As an alternative to surgery we performed a study to stabilize the prosthesis by percutaneous cement injection after removing inflammatory tissue with an intraarticular virus-directed enzyme prodrug approach. Twelve elderly patients with debilitating pain from a loosened hip prosthesis were included in a phase 1 dose-escalating clinical study. The patients were admitted to the hospital for 10 days for an intraarticular vector and prodrug injection, and subsequently for a percutaneous bone cement injection. This paper reports the adverse and serious adverse events of the study. After prodrug injection 9 of 12 patients had gastrointestinal adverse events (nausea, vomiting, and diarrhea), and 8 patients had hepatic adverse events (rise in aspartate aminotransferase and alanine aminotransferase). Five patients developed anemia (World Health Organization grade 1 or 2) from hematomas after cement injection. There were four serious adverse events in the first 6 months after vector injection, but these were not related to gene therapy as judged by an independent safety committee. There was no dose-limiting toxicity. However, the extensive comorbidity in these patients makes it difficult to fully establish the safety of the approach in this small and heterogeneous patient population.

A 20-year-old cow was presented due to chronic diarrhea and weight loss. The clinical examination revealed a markedly enlarged left ovary. However, a cause of the diarrhea could not observe. The examination of the feces was negative for a parasites or bacteria causing diarrhea. The results of hematological and biochemical analyses revealed a mild leucocytosis, bilirubinaemia, higher activities of the enzymes aspartate transaminase, gamma-glutamyltransferase and creatine kinase. The plasma concentrations of estrogen and testosterone were below the detection limits, progesterone concentration was 2.7 ng/ml. The postmortem examination revealed a bile ductule carcinoma with metastases in the lung and in lung and mestenterial lymph nodes. The cause of the tumor remained unclear. Diarrhea might have been the consequence of a portal hypertension due to the tumor. The pathological examination confirmed the clinical diagnosis of the ovarian tumor. The genesis of the ovarian tumor may be independent of the genesis of the bile ductule carcinoma.

The effects of a 90-day oral administration of water and alcohol extracts of dried calyx of Hibiscus sabdariffa were evaluated in albino rats. Haematological, biochemical and histopathological changes were monitored every 30 days.The death of the animals was preceded by a severe loss in weight, accompanied with diarrhoea in animals on the 2000 mg/kg dose. There was an increase in food intake (g) per kg body weight per day in the aqueous (A) and ethanol (E) 300 mg/kg extract groups. Significant reductions in the erythrocyte count with no difference in total leucocyte count were observed. The activity of aspartate aminotransferase (AST) was enhanced by the administration of aqueous and 50% ethanol extract with a significant increase in its level at higher doses (p < 0.05). Alanine aminotransferase (ALT) and creatinine levels were significantly affected by all the extracts at the different dose levels. However, aqueous extracts exhibited a significant increase in creatinine levels (p < 0.05) at higher doses. The cholesterol levels were generally not significantly affected by the extracts. No significant histopathological changes were observed, although there was a significant reduction in the weight of the spleen of the animals administered with ethanol and water extracts when compared with the control (p < 0.01). Other organs were of the same relative weight.
