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.

Acute zinc toxicosis from the ingestion of pennies was diagnosed in a dog with Heinz body hemolytic anemia (PCV = 14%), leukocytosis (51,000 cells/ml) with a left shift (3,060 band neutrophils; 37,740 segmented neutrophils) and monocytosis (4,080 cells/ml), azotemia (BUN = 60 mg/dl), bilirubinemia (total bilirubin = 5.3 mg/dl), hypokalemia (3.0 mEq/L), high serum alkaline phosphatase activity (691 U/L), high total plasma solids (8.1 g/dl), hemoglobinuria, and proteinuria. Despite aggressive medical treatment, renal failure ensued, and the dog died of cardiac arrest. The clinical signs, clinical course, and laboratory findings in this dog were similar to what has been reported in other cases of acute zinc toxicosis in dogs, with the exception of a history of generalized seizures and the findings of Heinz bodies. Although a causative relationship between plasma zinc values and Heinz body formation cannot be proven, their association suggests that oxidative damage to erythrocyte hemoglobin and cell membrane proteins may be involved in the pathogenesis of zinc-induced hemolysis.

A series of blood and urine samples was collected from each of eight normal foals between birth and eight weeks. Blood chemistry relating to renal function was evaluated as well as physical and chemical characteristics of urine. During the first 4d of life it was impractical to suggest meaningful normal values due to wide variation among foals and with time. Serum urea and plasma creatinine fell markedly to levels less than those previously reported for normal adult horses, while urine, mildly hypersthenuric at birth, rapidly became hyposthenuric. There was also a marked proteinuria during the first 48h. After 4d clinicopathological values stabilised. Urea and creatinine remained at subadult levels and hyposthenuria was maintained. While there was some variation with time, generally the urinary activity of gamma-glutamyl transpeptidase (GGT) and alkaline phosphatase (AP) was greater in foals than in adults; plasma potassium, the creatinine clearance ratio of potassium (% Cr K), serum inorganic phosphate and the creatinine clearance ratio of phosphate (% Cr PO4) were greater than in adults while plasma chloride and the creatinine clearance ratio of chloride (% Cr Cl) were lower in foals than in adults. Urinary pH was acidic and epithelial cells and calcium oxalate crystals more prevalent in the urine of foals than in that of adults. The information presented here will be useful in the diagnosis and management of renal disease and azotaemia in foals.

The pattern of serum proteins separated by SDS-PAGE is typified by the microprotein apolipoprotein A I which is split from high density lipoprotein by SDS. High density lipoprotein is generally retained by the glomerulus and does not appear in the urine even in glomerulopathies. Thus, apolipoprotein A I is generally absent in the SDS-PAGE protein pattern of renal proteinurias. However, in postrenal hematurias and proteinurias apolipoprotein A I can be found by SDS-PAGE, immunoblotting and Ouchterlony test. Using rabbit anti-human-apolipoprotein A I as primary antibody and alkaline phosphatase-conjugated anti-rabbit immunoglobulins as secondary antibody antibody apolipoprotein A I could be detected even at a 1:128,000 dilution of blood. This means a microhematuria of only 8 microliters blood/l urine theoretically can be identified as postrenal. Unfortunately, apolipoprotein A I is not only visible on the immunoblots of postrenal hematurias and proteinurias but could also be seen in renal proteinurias. Thus, only with reservation can apolipoprotein A I be called a marker of postrenal hematuria and proteinuria. On the other hand, most renal proteinurias can be identified reliably by SDS-PAGE and analysis of apolipoprotein A I is superfluous. Apolipoprotein A I, however, could become useful in the differentiation of microhematurias without proteinuria.

Multiple myeloma associated primary biliary cirrhosis (PBC) is very rare and only two cases have been reported. In this paper, we reported the first case of male patient with asymptomatic PBC and multiple myeloma. A 66 year-old Japanese male was referred to our hospital for the further examination of a monoclonal gammopathy. He was diagnosed of multiple myeloma (IgG-lambda type) because of 2.3 g/day of Bence Jones proteinuria (lambda type), 3,401 mg/dl of monoclonal IgG (lambda type), 12.8% of bone marrow plasmocytosis and generalized osteoporosis. The alkaline phosphatase was 314 mU/ml and serum IgM level (polyclonal) 937 mg/dl. The patient was started on intermittent courses of melphalan and prednisolone, achieving transient improvement. After two years, hepatosplenomegaly developed gradually and the levels of serum ALP elevated increasingly. At that time, relevant investigation results were: serum ALP 663 mU/ml, serum IgG 4,144 mg/dl, serum IgM 823 mg/dl, positive anti-mitochondrial antibody test x 320. The liver biopsy showed chronic nonsuppurative destructive cholangitis. PBC (stage 1-2 according to Sheuer's criteria) associated with multiple myeloma was diagnosed. A pathogenetic relationship such as loss of immunoregulatory function could be speculated although the simultaneous occurrence of PBC and multiple myeloma could be coincidental.

The association of IgA anti-gliadin antibodies and IgA glomerulonephritis (IgA GN) was first reported in 1987 (Am J Nephrol, 1987, 7, 178-183) and has since been confirmed by other groups. We have developed a second generation ELISA (alkaline phosphatase, biotin-avidin) and used it to test 45 adult IgA GN, 34 idiopathic membranous nephropathy (MN), 31 idiopathic nephrotic syndrome (INS), and 11 idiopathic membranoproliferative glomerulonephritis (MPG) patients. IgA anti-gliadin antibodies were found in 24 IgA GN (53%), 1 MN (3%), 1 INS (3%), and 1 MGP (9%) patients. The presence of these antibodies in a patient with proteinuria strongly suggests IgA GN, with a sensitivity of 53%, a specificity of 96%, a positive predictive value of 88% and a negative predictive value of 77%. The presence of IgA anti-gliadin antibodies in IgA GN did not necessarily indicate coeliac disease because: a) neither IgG nor IgA anti-reticulin nor IgA anti-endomysium antibodies were found; b) intestinal absorption tests (folates, EDTA) were normal; c) biopsies of the small intestine were normal; and d) a gluten-free diet did not alter the evolution of the disease. Immunochemical analysis (footprinting after separation of the gliadins by rocket electrophoresis) showed the variability of the fractions recognized by the IgA antibodies from patients and controls, in addition to the absence of a typical profile. Gliadin does not have a lectin effect, since mannan and mannose did not inhibit the ELISA. Immunofluorescent labeling of human kidney with purified rabbit IgG anti-gliadin antibodies did not reveal a common epitope shared by gliadin and renal structures.(ABSTRACT TRUNCATED AT 250 WORDS)

To identify early markers of the preclinical stage of diabetic nephropathy, a study was made of the activity of the specific canalicular enzymes in urine: N-acetyl-beta-D-glucosaminidase (NAG), beta-glucuronidase (beta-G1), gamma-glutamyl transferase (GGT), alkaline phosphatase (AP) and lactate dehydrogenase (LDH) in patients with diabetes mellitus without (26) and with (15) proteinuria. Patients without the clinical signs of diabetic nephropathy manifested a significant rise of excretion of lysosomal enzymes of the proximal canaliculi (NAG and beta-G1). Concomitant elevation of the excretion of several enzymes (NAG, beta-Gl, GGT and AP) was observed in 50% of cases. Patients with diabetic nephropathy demonstrated an increase of the excretion of all enzymes under study. Puncture biopsy of the kidneys was made in 4 patients without proteinuria with insignificant duration of diabetes mellitus and concomitant elevation of the excretion of a number of enzymes. Light microscopy revealed minimal changes in the glomeruli, whereas electron microscopy changes both in the glomeruli and in the canaliculi. The morphological changes in renal tissue confirm the diagnostic importance of high concomitant excretion of canalicular enzymes (NAG, beta-Gl, AP) as a marker of the preclinical stage of diabetic nephropathy.

A 6-year-old girl with cerebral palsy developed conscious disturbance and generalized convulsion after one-hour hot herb drug bath. Physical examination on admission revealed rectal temperature 41 degrees C, hot skin, respiration 46/min, regular heart beat 98/min, BP 130/60 mmHg, Glascow coma scale 4 (E2M1V1), soft and flat abdomen, no hepatosplenomegaly, no skin rash, no focal neurological sign, increased generalized muscle ton. Laboratory data showed CBC: WBC 20400 cumm (Neutrophils 31%, Lymphocytes 69%), Hb 11.6gm%, ESR 11 mm/hr, arterial blood gas: PH 7.077, PO2 43mmHg, PCO2 57.1mmHg, HCO3- 16 mEq/L, BE-11.5mEq/L, serum sodium 143 mEq./L, potassium 5.2 mEq/L, chloride 101 mEq/L, free calcium ion 3.8mg%, GOT 63IU/L, GPT 263 IU/L, amylase 193 IU/L, alkaline phosphatase 388 IU/L, LDH 1245 IU/L, CPK 677 IU/L, total bilirubin 0.8 mg/dl, direct type 0.1 mg/dl, BUN 18 mg/dl, Glucose 35 mg/dl. Urinalysis revealed proteinuria( ) trace hematuria and pyuria, but no cast. Lumbar puncture is within normal limits. Bacteriology including blood and CSF are normal. Multiple organ failure was noted at that time. Intensive cooling methods were performed including central and peripheral cooling. We used luminal and valium to control the seizure. Condition didn't improve. Afterwards cardiopulmonary arrest developed. Patient expired 8 hours after admission despite of resuscitation. Heat stroke in infancy and childhood is different from that in adulthood. The predisposing factors are high ambient temperature, dehydration, very young baby, sweat gland dysfunction, or ectodermal dysplasia. Definition of heat stroke includes 1) rectal temperature above 41 degrees C, 2) behavioral change, 3) warm skin, wet or dry.(ABSTRACT TRUNCATED AT 250 WORDS)

To assess the health significance of the early renal changes after chronic exposure to cadmium, 23 workers removed from exposure because of the discovery of an increased urinary excretion of beta 2-microglobulin or retinol binding protein, or both, have been examined once a year for five years. Eight of these workers had also an increased albuminuria. These workers had been exposed to cadmium for six to 41.7 years (mean 25 years) and their first follow up examination took place when they had been removed from exposure for six years on average. At that time, their mean age was 58.6 years (range: 45.5-68.1). It has been confirmed that the proteinuria induced by cadmium is irreversible. The most important finding, however, is a significant increase of creatinine and beta 2-microglobulin concentrations in serum with time, indicating a progressive reduction of the glomerular filtration rate despite removal from exposure. It is estimated that on average this rate has decreased by 31 ml/min/1.73 m2 during the five year follow up study. This decrease is significantly greater (about five times) than that accounted for by aging and is not more pronounced in workers with impaired renal function at the start of the study than in those presenting only with subclinical signs of renal damage. Serum alkaline phosphatase activity also increases significantly with time. In conclusion, the present study indicates that the early renal changes induced by cadmium should be regarded as adverse effects; they are predictive of an exacerbation of the age related decline of the glomerular filtration rate.

The urinary enzymes alanine amino-peptidase, alkaline phosphatase, gamma-glutamyltransferase and N-acetyl-beta-D-glucosaminidase and the two urine low-molecular mass proteins lysozyme and ribonuclease were measured in 30 healthy men and 36 insulin-dependent diabetics. 17 diabetics had "clinical proteinuria" (greater than 7.5 g/mol creatinine) and were defined as patients with manifest diabetic nephropathy. The remaining 19 diabetics were without proteinuria. The excretion rates of the two urine proteins and all enzymes except for gamma-glutamyltransferase were the highest in patients suffering from diabetic nephropathy. The excretion rates in both diabetic groups exceeded those of the control group. N-Acetyl-beta-D-glucosaminidase was more often increased than albumin in diabetics without manifest diabetic nephropathy. It is concluded that the tubular dysfunction is an early indicator of the incipient diabetic nephropathy. Thus, tubular parameters, especially the lysosomal enzyme N-acetyl-beta-D-glucosaminidase may be used in follow-up studies of diabetics.
