Whilst it is assumed that body growth is retarded in children with steroid-resistant nephrotic syndrome (NS), the degree of growth failure and the pathomechanisms involved are poorly understood. We collected serial growth data in 45 children (24 males) with steroid-resistant NS usually from onset to end-stage renal disease (ESRD) during childhood (n=10) or until final height was attained (n=27). Mean follow-up time was 9 (2-19) years. Mean initial standardized height was -0.3+/-1.2 standard deviation scores (SDS). Mean final height was +0.4 SDS in males and -1.0 SDS in females (sex difference not significant). In 16 patients with serum creatinine levels consistently <1.2 mg/dl, mean final height SDS was 0.3 SDS higher than that obtained within 6 months of onset. In contrast, 9 children who entered ESRD lost an average of 1.3 SDS from the initial record to ESRD (P=0.017). In prepubertal patients without renal insufficiency, mean height SDS decreased during corticosteroid treatment by 0.3 SDS, followed by a partial catch-up after discontinuation of treatment; the change from initial to final height SDS was inversely correlated with the total prednisone dose given (r=-0.50, P=0.03). In 16 prepubertal children with serial height and serum protein measurements who were off steroids and maintained normal creatinine levels, mean individual albumin concentrations correlated with the change in height SDS per year (r=0.65, P=0.0006) and in boys with final height (r=0.73, P=0.03). In conclusion, growth in steroid-resistant NS depends on the preservation of renal function, the cumulative dose of steroids applied, and the severity of hypoproteinemia.

Adriamycin widely used in the treatment of neoplastic conditions is nephrotoxic. In the present study the protective effect of lipoic acid was investigated in adriamycin-induced nephrotoxicity in adult male albino Wistar rats. Adriamycin-induced nephrotoxicity was characterized by hyperlipidemia, proteinuria, and hypoproteinemia, by decreased activities of the enzymes N-acetyl-beta-D-glucosaminidase and cathepsin D, by increased lipid peroxidation and decreases in serum catalase and glutathione activities, and by increased urinary and serum urea, creatinine and urinary glycosaminoglycans. Pretreatment with lipoic acid restored the changes, indicating that lipoic acid is renoprotective in adriamycin nephrotoxicity.

Large-scale clinical trials have shown that the oral adsorbent AST-120 improves renal function and delays the initiation of dialysis in chronic renal failure (CRF) secondary to chronic glomerulonephritis. If renal failure progresses via common mechanisms, then the same effects can be expected in diabetic nephropathy. However, no study on diabetic nephropathy has been reported. Thus, we enrolled patients with statistically significant progression of CRF secondary to diabetic nephropathy, and analyzed the changes in renal function after AST-120 therapy, and the clinical factors associated with response to therapy. We enrolled 276 patients with diabetic nephropathy, whose serum creatinine (Scr) had increased from 3.4 to 4.5 mg/dL during the 4.5 +/- 3.7 months prior to the study. These patients took AST-120 at a dose of 5.0 +/- 1.4 g/day for 6 months. The clinical data were analyzed by dividing the patients into three groups based on the changes in Scr after AST-120 therapy, with responders showing a decrease (N = 82), partial responders showing <1.5-fold increase (N = 144), and non-responders showing >/=1.5-fold increase (N = 50). AST-120 significantly lowered the slope of 1/Scr-time line, suggesting that AST-120 suppressed the progression of renal impairment. No responders required dialysis, whereas 24.3% of the partial responders and 36.0% of the non-responders started dialysis therapy. In responders, the 1/Scr-time slope showed a negative-to-positive shift and serum urea nitrogen decreased significantly, whereas the improvement was moderate in partial responders and minimal in non-responders. Among responders, AST-120 therapy significantly improved renal function despite the presence of hypoproteinemia, hyperlipidemia, anemia or hypertension in many patients. The beneficial effect of AST-120 was significantly more marked in patients with blood pressure controlled within the normal ranges and hematocrit maintained at 30% or above. AST-120 reversed renal dysfunction or delayed the initiation of dialysis therapy in patients with progressive aggravation of CRF secondary to diabetic nephropathy, independent of hypoproteinemia, hyperlipidemia, anemia and hypertension. Active use of AST-120 may be recommended in patients with good control of blood pressure and hematocrit above 30%.

Nephrotic syndrome (NS) remains a serious clinical setting characterized by marked proteinuria, hypoproteinemia and hypercholesterolemia, usually accompanied by the presence of oedemas. It could be presumed, that the newly discovered hormone leptin plays an important role in the complex metabolic processes occurring in patients with NS, in which apart from the changes in the hydratation, and the protein and lipid spectre profile changes, the alteration of the metabolism of glycides elicited by the treatment with corticosteroids (CS) is often observed. The aim of the study was to investigate the plasma levels of leptin and its plasma soluble receptor (sLe-R) before and after the treatment with CS and to evaluate their relationship with albuminemia and/or proteinuria. The study group consisted of 15 men and 15 women (mean age 49 +/- 13.7 years) with newly diagnosed NS, verified by renal biopsy, in which subsequently CS treatment was started. Before the treatment (period 1) and further one month (period 2) and six months (period 3) after the start of the treatment the following parameters were measured: body mass index (BMI), serum levels of creatinine, albumin, cholesterol, triglyceride, cholinesterase, proteinuria/24 hour and plasma levels of leptin and sLe-R. In comparison to the relatively high values of BMI in the period 1 a decrease of BMI towards the physiologic range was observed during the treatment periods. Statistically significant changes were also observed in proteinuria (decrease) and in serum cholesterol and albumin levels of whereas in other biochemical parameters, including plasma leptin and sLe-R levels, statistically significant changes were not found. A trend to negative correlation with borderline statistical significance could be observed between leptin and sLe-R. The results of our relatively unique study on leptin--dealing with long-term follow-up of the patients with NS suggest that regardless prominent metabolic alterations present in NS the plasma levels of leptin and sLe-R remain relatively stable, and that of regulation of leptin in this setting is probably complex and multifactorial.

Substantial fluid shifts occur during liposuction as wetting solution is infiltrated subcutaneously and fat is evacuated, causing potential electrolyte imbalances. In the porcine model for large-volume liposuction, plasma aspartate aminotransferase and alanine transaminase levels were elevated following liposuction. These results raised concerns for possible mechanical injury and/or lidocaine-induced hepatocellular toxicity in a clinical setting. The first objective of this human model study was to explore the effect of the liposuction procedure on electrolyte balance. The second objective was to determine whether elevated plasma aminotransferase levels were observed subsequent to large-volume liposuction. Five female volunteers underwent three-stage, ultrasound-assisted liposuction. Blood samples were collected perioperatively. Plasma levels of sodium, potassium, venous carbon dioxide, blood urea nitrogen, chloride, and creatinine were determined. Liver function analyte levels were measured, including albumin, total protein, aspartate aminotransferase, and alanine transaminase, alkaline phosphatase, gamma-glutamyl transpeptidase, and total bilirubin. To further define intracellular enzyme release, creatine kinase levels were measured. Mild hyponatremia was evident postoperatively (134 to 136 mmol/liter) in four patients. Hypokalemia was evident intraoperatively in all subjects (mean +/- SEM; 3.3 +/- 0.16 mmol/liter; range, 3.0 to 3.4 mmol/liter). Hypoalbuminemia and hypoproteinemia were observed throughout the study (baseline: 2.9 +/- 0.2 g/dl; range, 2.6 to 3.5 g/dl), decreasing to 10 to 40 percent 24 hours postoperatively (2.0 +/- 0.2 g/dl; range, 1.7 to 2.1 g/dl). Aspartate aminotransferase, alanine transaminase, and creatine kinase levels were significantly elevated after the procedure (190 +/- 47.1 U/liter, 50 +/- 7.7 U/liter, and 11,219 +/- 2556.7 U/liter, respectively) (p < 0.01). Release of antidiuretic hormone and even mildly hypotonic intravenous fluid infiltration have long been known to cause hyponatremia postoperatively. Intraoperative hypokalemia is associated with hypocarbia and respiratory alkalosis and the elevated epinephrine levels observed in the concurrent study. Factors having the greatest initial impact on diminished serum albumin and protein levels postoperatively are redistribution and hemodilution. Subsequent diminished viscosity may significantly affect postoperative hemodynamics. Elevated aspartate aminotransferase, alanine transaminase, and creatine kinase levels are associated with skeletal muscle injury, adipocyte lysis, and/or hepatic damage. Therefore, tissue injury is associated with large-volume liposuction as observed in several cellularly released enzymes. Future clinical studies are required to determine the degree of injury and specific tissues that are damaged or sensitive to mechanical trauma and/or drugs used in large-volume liposuction.

A 4.5-year-old female degu (Octodon degus) was minimally responsive with a poor body condition, a rough haircoat, and moderate dehydration. Blood was present around its urethral orifice and on the cage bedding. Laboratory analyses revealed leukocytosis with neutrophilia and anemia; hypoproteinemia and hypoalbuminemia; hyperglycemia, hyperphosphatemia, and elevated alanine aminotransferase, blood urea nitrogen, and creatinine; and hematuria and pyuria with occasional squamous and transitional epithelial cells. A urine culture was positive for coagulase-negative Staphylococcus sp. On gross necropsy, the right kidney was enlarged, cystic, and greenish-brown, with a 10-mm, hemorrhagic, granular mass extending from the renal pelvis into the cranial cortex. Only a small amount of renal cortex appeared normal. The urinary bladder had focal areas of hemorrhage and contained frank blood. Histologically, the papillary mass in the right renal pelvis comprised basophilic, moderately anaplastic, clustered epithelial transition cells consistent with a transitional cell carcinoma. Internally, the tumor showed squamous metaplasia and moderate multifocal interstitial fibrosis. The right kidney cortex contained a choristoma comprising trabecular bone, mature adipocytes, and cellular infiltrates suggestive of osteocytes, lymphocytes, and plasma cells. The urinary bladder had mild to moderate, focal, hemorrhage with neutrophilic inflammation and contained focal areas of mild transitional cell epithelial hyperplasia; these changes may have been secondary to irritation by hemorrhage in the renal pelvis. There was no evidence of metastasis. Renal transitional cell tumors are rare in rodents. This is the first report of both a renal transitional cell carcinoma and a renal choristoma in a degu.

The medical records of 19 horses with acute hemoperitoneum were reviewed. The causes for the hemoperitoneum were idiopathic (8 horses), splenic hematoma with capsular tear (7), bleeding from the reproductive tract (3), multicentric hemangiosarcoma (1), and systemic amyloidosis (1). The affected horses were between 4 and 32 years of age (median 11.5 years). The most consistent findings on initial examination were depression, tachycardia, tachypnea, pale mucous membranes, prolonged capillary refill time, colic, and abdominal discomfort. Less common clinical signs included abdominal distention, profuse sweating, ataxia, and broad ligament mass palpated on rectal examination. Clinicopathologic abnormalities commonly detected were anemia, neutrophilia, lymphopenia, thrombocytopenia, hypoproteinemia, hypocalcemia, azotemia, increased creatinine kinase, and sorbitol dehydrogenase activity. Hemoperitoneum was diagnosed on the basis of abdominocentesis, transabdominal ultrasonography, and postmortem examination. Sixteen horses were treated, and 3 horses were euthanized at owners' request because of severe clinical signs. The treatment consisted of the administration of intravenous fluids, plasma or blood transfusion, nonsteroidal drugs, antimicrobial drugs, and antifibrinolytic and procoagulant agents. Rapid clinical deterioration was observed in 2 horses, necessitating euthanasia. The remaining 14 horses survived the abdominal bleeding (survival rate 74%) and were discharged 3-15 days (median 7.0 days) after presentation. Postmortem examination of the 6 nonsurvivors showed massive abdominal hemorrhage from splenic hematoma with capsular tear (2 horses), multicentric hemangiosarcoma with liver rupture (1), systemic amyloidosis with splenic hematoma and capsular tear (1), and bilateral ruptured ovarian hematomas (1). In one horse, no origin of the bleeding could be determined during postmortem examination.

Antiproliferative and non-nephrotoxic properties of sirolimus have been exploited for treatment of patients with chronic graft dysfunction. In this paper we point to the possible association of nephrotic syndrome and renal impairment with rapid conversion from cyclosporine (CsA) to sirolimus in patients with chronic nephropathy. Five male patients, ages 34 to 56 years, with chronic renal failure in the course of glomerulonephritis, were transplanted between 1997 and 1999. For the first 49 to 65 months, the immunosuppressive regimen consisted of CsA, azathioprine (AZA), and prednisone. Thereafter, due to chronic nephropathy evidenced by biopsy, conversion to sirolimus was performed with sharp withdrawal of CsA. The serum creatinine level prior to conversion was 1.9 +/- 0.3 mg/dL. Trace to 86 mg/dL proteinuria was found in 3 patients, while 2 patients had about 200 mg/dL. After 2 to 4 months of sirolimus treatment the proteinuria progressed (558 +/- 183 mg/dL); edema, hypoproteinemia, hypoalbuminemia, and hyperlipidemia developed; and the serum creatinine increased to 3.5 +/- 0.8 mg/dL. Biopsies performed in three patients revealed new pathologic changes. After 4 to 5 months, we performed reconversion to calcineurin inhibitor. Proteinuria decreased to 0 to 150 mg/dL; nevertheless the serum creatinine was continuously rising. Six to 15 months after the conversion, 3 patients returned to dialysis. The fourth patient, who was earlier reconverted, has a serum creatinine level of 2.0 mg/dL after 15 months. In conclusion, conversion from CsA to sirolimus may induce nephrotic syndrome with progressive deterioration of renal function. Converted patients require careful monitoring of proteinuria and renal function. Early reconversion to calcineurin inhibitor may prevent progressive deterioration of graft function.

Clinical and hematological changes observed on presentation of 47 horses referred to the Ontario Veterinary College with acute idiopathic colitis were analyzed for their prognostic features. Cases of acute enterocolitis were characterized by fever, dehydration, abnormalities of serum electrolyte concentrations, azotemia, hypoalbuminemia, and increased serum concentrations of muscle enzymes. Severely dehydrated horses were seven times more likely to die or be euthanized than those that were not dehydrated. Other factors associated with failure to survive included the following: increased hematocrit, increased number of band neutrophils, increased serum creatinine and urea concentrations, and decreased blood pH and increasingly negative base excess. The results of multivariate variable analysis (stepwise logistic regression) suggested that, among the variables tested, base excess was the best predictor of death or survival. Twenty of 47 horses died or were euthanized. Reasons for death or euthanasia included: severe disseminated intravascular coagulation, unresponsiveness of severe metabolic acidosis and hypoproteinemia to treatments, and severity of colonic lesions on exploratory laparotomy. Of the surviving horses, three developed chronic laminitis (two were destroyed) and five developed jugular vein thrombosis. Fourteen of 16 horses for which subsequent histories were available returned to normal function.Early recognition of the disease, combined with early and aggressive correction of dehydration and of acid-base imbalance, may be important determinants of survival in horses with acute idiopathic colitis.

Light chain deposition disease (LCDD) damages most frequently kidneys, and less frequently other organs. The incidence of LCDD is lower than the incidence of AL-amyloidosis. Symmetric swelling of both legs was the first sign of nephrotic syndrome with renal insufficiency in our female patient. Renal biopsy specimen revealed the diagnosis of LCDD. Bone marrow biopsy contained 40% of plasma cells. Bone survey showed no osteolytic changes. These findings confirmed the diagnosis of multiple myeloma (MM) Durie Salmon stage IB with LCDD. The patient was initially treated with 4 cycles of VAD (vinkristine, adriamycine, dexamethasone) chemotherapy with no response. Followed collection of peripheral haematopoietic stem cells and later high dose chemotherapy with reduced dose of melphalan 140 mg/sqm and autologous peripheral haematopoietic stem cells transplantation. Melphalan dose was reduced because of renal insufficiency (serum creatinine 290 micromol/l) before application of conditioning regimen. High dose therapy was complicated by with deterioration of renal function, creatinine increased to 600 micromol/l. Worsening of renal function was most likely caused by nephrotoxicity of melphalan in nephrotic syndrome. This has been previously described in patients with AL-amyloidosis, and nephrotic syndrome who were treated with high dose melphalan. This phenomenon was entitled "post conditioning renal insufficiency". Hypoalbuminemia hypoproteinemia and reduced intravascular volume and renal damage caused by amyloid deposits as well as probably, amorphous non-amyloid deposits of monoclonal immunoglobulin are likely to have contributed to nephrotoxicity of the high dose of melphalan. However, worsening of renal insufficiency was facilitated by the mucositis-associated sepsis. Follow-up examination one month after high dose chemotherapy showed complete remission, that was confirmed by further examinations. In the course of the first year after high dose chemotherapy renal function gradually improved and nephrotic syndrome completely disappeared (complete kidney remission). Proteinuria declined to 2-3 g/24 hours and glomerular filtration slowly improved. Three years after high dose chemotherapy the patient is still in complete remission of multiple myeloma and free of nephrotic syndrome, with slightly increased creatinine (160 micromol/l) that, nevertheless, has had an improving tendency over last 3 years. The present case study illustrates accomplishment of complete haematological remission with high dose chemotherapy followed by autologous haematopoietic stem cells transplantation despite complete resistance of the disease to the standard chemotherapy VAD in a patient with MM and LCDD. We draw the reader's attention to the possibility of nephrotoxic effects of high dose melphalan (post conditioning renal insufficiency) in patients with nephrotic syndrome caused by light chain deposits as AL-amyloid or amorphous light chains deposits (LCDD)and we document the importance of plasma free light chain detection.
