Dose- and time-related effects of Cd (II) (0.5 or 1.0 mg/kg, Cd as CdCl2.H2O, subcutaneously, daily for 48 h, 1, 3, or 6 wk) were investigated in rats. A dose-related increase in the activity of plasma alkaline phosphatase (ALP), lactate dehydrogenase (LDH), aspartate aminotransferase (GOT), and alanine aminotransferase (GPT) was evident only at 6 wk, whereas an early rise in ALP and LDH was seen at 3 wk in 1.0 mg Cd group only. The hepatic and renal metallothionein (MT) induction displayed a dose- as well as time-related increase with Cd accumulation. A significant increase in hepatic Zn and renal Cu, no change in hepatic Cu, and a slight increase in renal Zn was observed. Urinary ALP and leucine aminopeptidase (LAP) showed an initial increase at 48 h, thereafter returned to near normal. A second phase of enzymuria (ALP, LAP, GOT, GPT, gamma-glutamyl transpeptidase), proteinuria, and aminoaciduria occurred at 6 wk in a dose-related manner. The urinary excretion of specific renal enzymes appeared closely related to the MT induction and organ Cd levels.

A comparison of the effects of intraperitoneal and subcutaneous routes of administration of sodium dichromate on nephrotoxicity in rats was studied. Dichromate when injected subcutaneously (SC group) produced a higher degree of nephrotoxicity than when administered intraperitoneally (IP group). It caused severe progressive proteinuria followed by polyuria and glucosuria, reaching maximum levels at 3 days after treatment in the SC group, whereas it produced mild proteinuria without glucosuria in the IP group. The dose-dependent increases in blood urea nitrogen (BUN) and creatinine concentrations, shown in the SC group, were not observed in the IP group. However, between the two groups, there were no great differences in either the urinary excretion rate of chromium or the electrophoretic patterns of urinary protein in the day 1 urine specimens. Pretreatment of phenobarbital (PB) had no remarkable effect on the dichromate-induced nephrotoxicity. In contrast, it potentiated dichromate-induced hepatotoxicity, the indices of which were the elevation in serum alanine aminotransferase (ALT) activity and hepatic lipid peroxide formation. These results suggest that the dependence of dichromate-induced nephrotoxicity on the route of administration is related to the chemical forms of chromium reaching the kidney, and the necrotizing property of dichromate results from its metabolic fate in vivo.

Six male and 6 female Beagles, 6 to 7 months old, were allotted to 2 groups: group I--inoculated subcutaneously with 30 Dipetalonema reconditum infective larvae/dog, and group II--noninoculated controls. Group comparisons were made in regard to hematologic values, Knott test results, body weights, blood urea nitrogen, total serum protein, serum albumin and alanine aminotransferase and creatine kinase activities. Routine urinalysis data were compared at 1 week before and at 28 weeks after the inoculations. Mean total leukocyte counts were significantly (P less than 0.05) greater in group I dogs than in group II dogs at postinoculation weeks (PIW) 4, 5, and 7 to 12, and mean eosinophil counts were significantly greater in group I dogs at PIW 3 to 11, 13 to 15, 20, and 23 to 24. Microfilariae were detected as early as the 10th week and sporadically thereafter. Only 1 D reconditum adult worm was recovered from all of the inoculated dogs. Five other dogs (group III) with chronic, patient experimentally induced dipetalonemiasis, were evaluated with the same tests at PIW 70 to 89. Eosinophilia (greater than 750 cells/microliter) was present in 4 of 5 dogs; lymphocytosis (greater than 4,800 cells/microliter) was evident in 1 dog. Proteinuria (greater than or equal to 30 mg/dl) was detected in 3 of 4 dogs with chronic dipetalonemiasis.

Possible risk factors associated with mortality were studied in a community using data derived from annual mass health examinations for the aged mandated by law. A total of 1,804 adults (685 men and 1,119 women) aged 40 or older in A-town, located on Tsushima Island, Nagasaki Prefecture, Japan who had participated in annual health examinations at least once between 1984 and 1990, were followed for a mean period of 4.9 years. After adjustment for age using Cox proportional hazards models, in men liver dysfunction (aspartate aminotransferase > 40 U/l or alanine aminotransferase > 35 U/l), fasting blood glucose > or = 110 mg/dl and glucosuria, and in women serum creatinine > or = 1.2 mg/dl, fasting blood glucose > or = 110 mg/dl and proteinuria were found to be associated with a significantly increased risk of total mortality. In multivariate analysis using all independent variables that were significantly associated with mortality in age-adjusted bivariate analysis, in men liver dysfunction and hyperglycemia, and in women hypercreatininemia and hyperglycemia, were significant predictors of mortality. These independent variables remained significant or marginally significant predictors of total mortality even after excluding the effects of 3 pancreatic cancer cases with liver dysfunction or hyperglycemia or 12 deaths within the first year of follow-up, being associated with at least two-fold increased hazard rate ratios. From these results, it is recommended that persons with these risk factors be followed intensively and counseled by public health personnel to modify risk factors.

Two dogs were seen at the University Veterinary Teaching Hospital, Nairobi, Kenya, both having histories of dyspnoea, progressively enlarging abdomens, anasarca, ascites, pleural and pericardial effusion, and pulmonary oedema. One of the dogs had a mild neutrophilic leucocytosis, elevated levels of alkaline phosphatase, alanine aminotransferase, lactate dehydrogenase and proteinuria. Histopathological examination of the myocardium revealed some damage to myocytes and a mononuclear cellular infiltration involving the myocardium, liver and kidneys. The two dogs had a fondness for avocado fruits and, as the presenting syndrome is identical to that seen in goats, sheep and horses poisoned by avocados, a comparison is made and the probable manifestation of this poisoning presented.

Halogenated anilines and aminophenols are nephrotoxicants and hepatotoxicants in mammals. The purpose of this study was to determine the in vivo and in vitro nephrotoxic and hepatotoxic potential of 4-amino-2,6-dichlorophenol, a putative metabolite of 3,5-dichloroaniline. In the in vivo experiments, male Fischer 344 rats (four/group) were administered a single intraperitoneal (i.p.) injection of 4-amino-2,6-dichlorophenol (0.25, 0.38 or 0.50 mmol/kg) or vehicle (dimethylsulfoxide (DMSO), 1.0 ml/kg) and renal and hepatic function monitored for 48 h. Only minor changes in function or morphology were observed in the 0.25 mmol/kg treatment group. However, in the 0.38 mmol/kg treatment group evidence of both nephrotoxicity and hepatotoxicity were evident. Nephrotoxicity was characterized by increased proteinuria, glucosuria, hematuria, elevated blood urea nitrogen (BUN) concentration and kidney weight, decreased p-aminohippurate (PAH) accumulation and proximal tubular necrosis in the corticomedullary region of the kidney. Hepatotoxicity was characterized by elevated plasma alanine aminotransferase (ALT/GPT) activity and liver weight. Animals administered the 0.5 mmol/kg dose died within 24 h. In the in vitro experiments, the effect of 4-amino-2,6-dichlorophenol on organic ion accumulation, gluconeogenesis and lactate dehydrogenase (LDH) leakage was quantitated in liver and/or renal cortical slices. Organic anion accumulation was inhibited in renal cortical slices by 4-amino-2,6-dichlorophenol bath concentrations of 5 x 10(-6) M or higher, while organic cation uptake was decreased at 4-amino-2,6-dichlorophenol bath concentrations of 1 x 10(-5) M or greater. Renal and hepatic pyruvate-stimulated gluconeogenesis were inhibited and renal LDH leakage increased at 4-amino-2,6-dichlorophenol bath concentrations of 5 x 10(-5) M or greater. Increased LDH leakage from liver slices was not observed. These results demonstrate that 4-amino-2,6-dichlorophenol is a nephrotoxicant and hepatotoxicant in vivo and in vitro and that the kidney is more susceptible to 4-amino-2,6-dichlorophenol toxicity than the liver.

To improve the efficacy of interferon (IFN) in the treatment of chronic hepatitis C, administration of IFN-beta twice per day was evaluated. Thirty-eight patients with chronic hepatitis C (26 males and 12 females, aged 25-67 years) were included. Patients were treated with a new protocol that included twice-daily treatment with IFN-beta. Three million units (MU) of IFN-beta was administered twice daily every day for 4 weeks followed by 10 MU of IFN-alpha2b, every day for 2 weeks and then three times a week for 18 weeks (total IFN-beta, 148 MU; IFN-alpha2b, 680 MU). Complete responders (CR) were defined by alanine aminotransferase levels that normalized within 6 months after completion of IFN therapy and remained normal for more than 6 months, and by serum hepatitis C virus (HCV) RNA levels that became negative as determined using the Amplicor assay. Twenty-one of 38 (55.3%) patients were CR. Nine of 21 (42.9%) patients with HCV serotype 1 were responders compared with nine of 12 (75.0%) patients with HCV serotype 2. In patients with an HCV titre greater than 1 million equivalents ml-1 (1 MEq ml-1), nine of 24 (37.5%) responded, and in patients with HCV titres less than 1 MEq ml-1, 12 of 14 (85.7%) responded. In patients with HCV serotype 1 and greater than 1 MEq ml-1 HCV RNA, four of 15 (26.7%) responded to IFN. Two-thirds (66.7%) of the patients who became negative for HCV RNA after 2 weeks of therapy responded, while 72.7% of those with positive HCV RNA after 2 weeks of therapy were non-responders. Proteinuria was frequently observed as an adverse effect of twice-daily administration of IFN-beta. The combination of twice-daily administration of IFN-beta for 4 weeks followed by IFN-alpha showed a high response rate in patients with chronic hepatitis C, but in patients with both serotype 1 and a high titre of HCV RNA, response rates were still low. Thus, the HCV RNA titre 2 weeks after starting therapy with IFN was useful for predicting the eventual response to IFN.

A 66-year-old female was admitted to our hospital in January, 1998, complaining of low grade fever and muscle weakness of her legs. Physical examination revealed muscle weakness of her neck (4/5) and proximal skeletal muscles of her bilateral legs (3/5-4/5). She showed proteinuria and microhematuria. Her serum levels of ureanitrogen, creatinine, aspartate aminotransferase, alanine aminotransferase, creatinekinase, aldolase and myoglobin were all within the normal ranges. Antinuclear antibodies were negative, but her serum levels of pANCA (743 EU) and C reactive protein (18.0 mg/dl) were elevated. Neuroconduction velocity of her left common peroneal nerve was decreased to 40.8 m/sec and electric myograph showed neurogenic changes. Magnetic resonance images (MRI) of her bilateral thigh depicted high signal intensity in quadriceps by T 2 weighed images, but the signals were not enhanced by gadolinium injection. Muscle and renal biopsies revealed necrotizing vasculitis of the small arteries. Crescentic glomerulonephritis was also observed by renal biopsy. These findings supported the diagnosis of microscopic PN. On 16 th admission day, she developed acute cardiac and respiratory failures due to cardiac and respiratory muscle involvements with PN, and was assisted by mechanical ventilation. She was treated with methylprednisolone pulse therapy (500 mg/day, three consecutive days) on 18 th admission day, followed by 40 mg of oral prednisolone daily. However, her symptoms deteriorated, and herserum creatinine levels increased to 2.4 mg/dl. On 24 th admission day, intravenous cyclophosphamide pulse therapy (500 mg/day) was instituted. Her cardiac wall motion on echocardiography and serum creatinine levels gradually improved, but her skeletal and respiratory muscle weakness did not improve. On 38 th admission day, she was complicated with respiratory infection by methicillin resistant Staphylococcus aures. On 62 th admission day, she died of endotoxic shock. This is the first report describing respiratory muscle involvement with PN, and the second report describing MRI findings of muscle involvement by PN. Therefore, our case provides important clinical information for the diagnosis and treatment of the disease.

Infestation with a short-tailed demodectic mite and Demodex canis was diagnosed in both a six-and-a-half-year-old and a four-year-old dog. The clinical picture was compatible with generalised demodicosis complicated by staphylococcal pyoderma (case 1), or localised demodicosis (case 2). In both cases, the short-tailed demodectic mite outnumbered D canis in superficial skin scrapings. The laboratory findings (lymphopenia, eosinopenia, increased serum alkaline phosphatase and alanine aminotransferase activities, diluted urine and proteinuria) and the results of a low dose dexamethasone suppression test were suggestive of underlying hyperadrenocorticism in the first case. Hypothyroidism was considered a possibility in the second case, owing to the sustained bradycardia and the extremely low basal total thyroxine value. Systemic treatment with ivermectin and cephalexin (case 1), or topical application of an amitraz solution in mineral oil, along with sodium levothyroxine replacement therapy (case 2), resulted in a complete resolution of the skin lesions and the disappearance of both types of demodectic mite after two and one and a half months, respectively.

Ovarian hyperstimulation syndrome (OHSS) is a potentially fatal condition associated with the use of ovulation-inducing drugs. We describe a 28-year-old woman who presented with ascites, oliguria and vomiting. Over 2 weeks, the combination of intractable vomiting, intravenous rehydration, paracentesis, hypercatabolism and proteinuria led to severe hypoalbuminaemia with gross oedema and progressively worsening liver function. The patient's albumin dropped to 9 g/l with liver function abnormalities peaking at: alanine aminotransferase, 462 IU/l; alkaline phosphatase, 706 IU/l; bilirubin, 26 micromol/l; and prothrombin time, 19 s. The judicious use of paracentesis and commencement of total parenteral nutrition coincided with a rapid clinical improvement. One month after discharge, the patient was asymptomatic with normal liver function. This case demonstrates the severity of malnutrition and liver dysfunction that can occur with severe OHSS. Increasing use of in-vitro fertilization techniques makes it mandatory for clinicians to be aware of the clinical features, complications and treatment of this condition, and we would suggest that patients with severe OHSS should be jointly managed by physicians and obstetricians.
