Acute renal failure was diagnosed by clinical, necropsy and histological criteria in 39 flocks (20 low ground, 13 hill and six marginal upland) in areas served by six veterinary investigation centres. Forty-eight lambs of 12 different breeds or crosses were investigated. The mean age of affected lambs was 38 days (range seven to 84 days); 21 lambs (44 per cent) were aged seven to 28 days, while only eight (17 per cent) were older than two months. Mortality in clinically affected lambs was almost 100 per cent, with no response to various treatments. Histological examination showed that 40 lambs (83 per cent) had nephrosis, while the rest had toxic tubular necrosis, interstitial nephritis or tubular damage associated with oxalate crystal deposits. Only about half of the lambs had any evidence of enteric infections or enteropathy. Acutely ill lambs had azotaemia, haemoconcentration and proteinuria; some lambs had glycosuria or haematuria. Samples of plasma from 22 lambs with nephrosis were compared with similar samples from 82 incontact but asymptomatic lambs. The clinically affected group had significantly elevated plasma urea, creatinine, total protein, globulin, phosphorus and chloride concentrations and significantly reduced plasma calcium concentrations compared with healthy lambs. Affected lambs had a significant reduction also in the calcium:phosphorus ratio. No significant differences between groups was found in plasma concentrations of albumin, glucose, lactate, glycerol, creatine kinase, alkaline phosphatase, sodium, potassium or magnesium.

Daily blood and 24-hour urine samples from 6 runners were studied for 2 days before and for 5 days after a 42.2 km. marathon footrace run in cool environmental conditions. Although the race caused muscle damage as shown by the increased post-race serum creatine kinase activity and C-reactive protein levels, renal function measured by urine flow rates, creatinine clearance and protein excretion was normal during the race. Sodium and fractional sodium excretion decreased during the race despite a maintained osmolar clearance, and remained low for the next 48 hours, whereas osmolar clearance decreased sharply for the remainder of the race day but it was significantly elevated on days 2 to 4 after the race. Creatinine clearance was increased significantly 24 hours after the race, and reached its peak 3 days after the race, while urine flow rates were elevated from days 2 to 5 after the race. Urea excretion was significantly decreased 3 to 5 days after the race, while creatinine excretion was increased significantly on day 3 after the race. Glomerular proteinuria occurred 24 hours after the race with no associated reduction in tubular reabsorption of the low molecular weight protein beta-2-microglobulin. This study shows previously unrecognized substantial delayed effects of prolonged exercise on renal function. The nature of these changes may reflect catabolic followed by anabolic processes in muscle as well as changes consequent on excess sodium retention and related fluid compartment shifts.

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.

Abnormal myoglobinemia (above 77 microgram/l) and free hemoglobin in plasma were found in 16 runners and in nine non runners immediately following distance running. The same abnormalities were found iun six elite rowers following rowing. In parallel with the rise in myoglobin and free hemoglobin a rise was found in serum concentrations of cellular enzymes (LDH, CK, ASAT, alkaline phosphatase) and of various metabolites. We found no proteinuria nor casts in the urine. Non runners had a higher rise in serum myoglobin than runners. Competitive running caused a rise in the serum concentration of the heart specific fraction of creatine kinase in seven of the nine (healthy) elite runners. The abnormal findings are only explainable on the basis of leakage of proteins from muscle cells to the circulation in otherwise healthy, well trained persons. Myoglobinemia and a transient rhabdomyolysis is a common phenomenon in long distance running, but evidently also occurs in distance rowing. Three months of running training prevented most of the muscle damage from relaxed jogging in the nine previous non runners. Neither the observed myoglobinemia nor the hemoglobinemia resulted in any significant loss of iron in the urine.

Two girls with mixed connective tissue disease (MCTD) were treated in our hospital in the past 5 years. Patient 1, a 10-year-old girl presenting with migratory arthralgia, had an initial diagnosis of juvenile rheumatoid arthritis. Muscle weakness with elevated levels of creatine kinase and liver enzymes, sclerodactyly, Raynaud's phenomenon and heliotrope sign developed subsequently in the following 3 years. Patient 2, a 13-year-old girl, had been treated for suspected systemic lupus erythematosus since 9 years of age. She presented with lymphadenopathy, arthralgia, pericardial effusion, and paralytic ileus. The symptoms waxed and waned. Sclerodactyly, Raynaud's phenomenon, proteinuria, and hypertension were also noted. Both patients had high serum titers of antinuclear antibody (speckled pattern, 1:5120) and were seropositive for antiribonuclear protein antibody. Intravenous immunoglobulin, prednisolone, cyclosporine A, and nonsteroidal anti-inflammatory drugs (NSAIDs) were given to patient 1. Patient 2 received cyclosporine A, prednisolone, and methylprednisolone pulse therapy. The disease has been well controlled for 2 years by low-dose immunosuppressants and NSAIDs. MCTD is a rare juvenile rheumatic disease: early identification and appropriate treatment can improve the disease outcome.

The activities of the enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LD), creatine kinase (CK), amylase (AMS) and angiotensin converting enzyme (ACE) have been used to assess the toxic effects of xenobiotics that have hypoglycaemic action in hepatic, pancreatic, renal and muscle tissue. Using a validated experimental model of diabetes mellitus in rats, we ascertained whether this syndrome itself affected the serum activities of these enzymes over a 53-day period. Levels of hepatic enzymes AST, ALT and ALP were higher in the streptozotocin (STZ)-diabetic rats (group D), but were controlled by insulin therapy (group DI). AMS was reduced in group D and unchanged in group DI rats. Proteinuria was detected 1 day after STZ administration and partially controlled by insulin (group DI); its early presence in group D rats, and the lack of any change in serum ACE in this group, indicates that proteinuria is the better marker for microangiopathy. Microscopic examination of liver, kidney, heart and skeletal muscles (soleus and extensor digitorum longus) revealed various alterations in group D rat tissues, which were less pronounced in group DI. The liver, pancreas and kidney tissue-damage was consistent with the altered serum levels of AST, ALT, ALP and AMS and proteinuria. We conclude that: (i) rigorous control is required when these serum-enzyme levels are used as indicators of tissue toxicity in experimental diabetes, and (ii) LD, CK and bilirubin serum levels, which are unaffected by diabetes, can be used when testing effects of xenobiotics on tissues.

We present four adult cases of acute renal failure associated with hypothyroidism. All patients presented with symptoms suggestive of moderate to severe hypothyroidism, such as cold intolerance, constipation, muscle weakness, and lower extremity oedema. Initial serum creatinine levels ranged between 115 and 203 micromol/L (1.3 and 2.3 mg/dL), with creatinine clearances (CrCl) ranging between 0.58 and 0.97 mL/s (34.5 and 58 mL/min). After 6-12 weeks of treatment with levothyroxin, serum creatinine levels decreased to the range of 80 and 124 micromol/L (0.9 and 1.4 mg/dL) and CrCl increased to 0.74-1.64 mL/s (44-98 mL/min). One patient had proteinuria of 800 mg/day, which decreased to the normal range (<200 mg/day) after levothyroxin treatment. One patient developed acute gouty arthritis before normalization of thyroid-stimulating hormone (TSH), which was successfully managed with prednisone therapy. All of our patients had increased creatine kinase (CK), ranging between 1000 and 2360 U/L (normal range, 22-165 U/L), which normalized after 6 weeks of levothyroxin treatment.

The safety and tolerability of rosuvastatin were assessed (as of August 2003) using data from 12,400 patients who received 5 to 40 mg of rosuvastatin in a multinational phase II/III program, which represented 12,212 patient-years of continuous exposure to rosuvastatin. An integrated database was used to examine adverse events and laboratory data. In placebo-controlled trials, adverse events, irrespective of causality assessment, occurred in 57.4% of patients who received 5 to 40 mg of rosuvastatin (n = 744) and 56.8% of patients who received placebo (n = 382). In fixed-dose trials with comparator statins, 5 to 40 mg of rosuvastatin showed an adverse event profile similar to those for 10 to 80 mg of atorvastatin, 10 to 80 mg of simvastatin, and 10 to 40 mg of pravastatin. Clinically significant elevations in alanine aminotransferase (>3 times the upper limit of normal) and creatine kinase (>10 times the upper limit of normal) were uncommon (<or=0.2%) in the groups that received rosuvastatin and comparator statins. Myopathy (creatine kinase >10 times the upper limit of normal with muscle symptoms) that was possibly related to treatment occurred in <or=0.03% of patients who took rosuvastatin at doses <or=40 mg. A positive finding of proteinuria with dipstick testing at rosuvastatin doses <or=40 mg was comparable to that seen with other statins, and the development of proteinuria was not predictive of acute or progressive renal disease. No deaths in the program were attributed to rosuvastatin, and no rhabdomyolysis occurred in patients who received 5 to 40 mg of rosuvastatin. Rosuvastatin was well tolerated by a broad range of patients who had dyslipidemia, and its safety profile was similar to those of the comparator statins investigated in this extensive clinical program.

In a large randomized trial of statin therapy in patients of South-Asian origin with hypercholesterolemia, 740 patients in the United States and Canada received 6 weeks of treatment with rosuvastatin 10 or 20 mg or atorvastatin 10 or 20 mg. A total of 485 patients (66%) were categorized as being at high risk of coronary heart disease and had a National Cholesterol Education Program Adult Treatment Panel III treatment goal of low-density lipoprotein (LDL) cholesterol <100 mg/dl (<2.6 mmol/L). LDL cholesterol decreased by 45% with rosuvastatin 10 mg versus 40% with atorvastatin 10 mg (p = 0.0023) and by 50% with rosuvastatin 20 mg versus 47% with atorvastatin 20 mg (p = NS). National Cholesterol Education Program Adult Treatment Panel III LDL cholesterol goal achievement rates in high-risk patients (all patients) were 76% (79%) and 88% (89%) with rosuvastatin 10 and 20 mg, respectively, compared with 70% (76%) and 81% (85%) with atorvastatin 10 and 20 mg, respectively. Rosuvastatin and atorvastatin were well tolerated. There were no clinically relevant differences between statins in adverse events or incidence of creatine kinase >10 times the upper limit of normal, alanine aminotransferase >3 times the upper limit of normal on 2 consecutive occasions, or proteinuria or hematuria over the relatively short duration of treatment. In conclusion, statin therapy was well tolerated and effective in decreasing LDL cholesterol in patients of South-Asian origin, with the 10- and 20-mg doses of rosuvastatin and atorvastatin allowing most patients to reach recommended LDL cholesterol goals.

We report the exercise capacity of an 8-year-old boy with clinical, histological, biochemical, and genetic evidence of McArdle disease. The patient presented with severe myalgia, proteinuria, hematuria, pyrexia, and elevated creatine kinase after swimming. After pre-exercise ingestion of sucrose, he performed treadmill exercise to symptom limitation. His peak oxygen uptake (18.8 mL/kg/min) and ventilatory threshold (16.0 mL/kg/min) were reduced by 40% and 20% compared with healthy age-matched and gender-matched controls. The results suggest that exercise capacity is reduced early in life in patients with McArdle disease and suggest the need for prophylactic exercise training (following pre-exercise feeding to prevent rhabdomyolysis) to minimize deconditioning.
