An unusual case of a patient developing severe coagulopathy disorder and a clinical picture of cerebral hemorrhage and acute renal failure after young Bothrops jararacussu snake bite is reported. The mechanisms of snake venom-induced injury are discussed and similar cases in literature are revised and compared. The use of bothropic-Crotalus antivenom in severe B. jararacussu envenomation is discussed. 相似文献

A case of myoglobinuria with acute renal failure in a 29-year-oldmale is presented. The attack followed a minor operation undergeneral anaesthesia during which suxamethonium was administeredas muscle relaxant. Immediately after the injection of suxamethoniumvigorous generalized fasciculations occurred which very likelyproved to be the precipitating factor for the episode of rhabdomyolysis.It is concluded that the use of depolarizing agents in patientswith myoglobinuria is hazardous and should be avoided. 相似文献

Salmonella enteritidis infection occurs primarily in animals and often results in self-limited gastroenteritis in accidental cross contamination in human. However, the acute renal failure could be a rare but serious complication of the S. enteritidis infection. We report one case of acute renal failure from severe dehydration caused by S. enteritidis food poisoning. The acute renal failure completely recovered after hydration and antibiotic treatment. 相似文献

We report a patient with neuroleptic malignant syndrome (NMS) who developed acute renal failure and was successfully treated by hemodialysis. A 60-year-old man with a 26-year history of schizophrenia had been treated with thioridazine and sulpiride. He was admitted to our hospital for muscular rigidity and oliguria. After the diagnosis of NMS with acute renal failure was established, thioridazine and sulpiride were discontinued and hemodialysis was instituted. Renal function gradually improved and hemodialysis was discontinued after 17th treatment. We also reviewed 57 cases of NMS with acute renal failure reported in the literature. To our knowledge, 26 years is the longest latency between initiation of neuroleptic drug treatment and onset of NMS. Our review of reported NMS cases with acute renal failure identified those risks for poor prognosis as high level of BUN, age and female gender. 相似文献

Hepatocyte growth factor (HGF) facilitates the regeneration of injured kidney in acute renal failure (ARF). HGF is produced as a single-chain precursor by cells of mesenchymal origin and is converted to a biologically active, heterodimeric molecule by proteol ytic processing.We studied HGF mRNA and protein levels in systemic organs of glycerol-induced ARF rats, a model of crush syndrome. HGF protein concentration of tissue homogenate was measured by ELISA. Both mRNA and protein levels were increased in liver and spleen at 24 hours after the glycerol injection whereas HGF protein level was decreased in the injured kidney. Expression of HGF receptor/c-met mRNA was elevated only in the kidney. These results suggest that HGF supplied in an endocrine manner may play an important role in the regenerating process following ARF.Next, we measured serum HGF concentration by ELISA in 8 ARF patients caused by crush syndrome and the molecular size of serum HGF was determined byimmun oblotting. Although serum HGF levels elevated in all patients, the HGF levels did not associate with their prognoses. While a single-chain molecule was predominantly observed in sera from chronic renal failure patients and healthy subjects, the majority of serum HGF was a heterodimeric form in 7 ARF patients. In one patient who developed disseminated intravascular coagulation syndrome and had a poor prognosis, a single-chain molecule was predominant although the serum HGF concentration was equivalent. These data suggest that the activity of proteolytic processing may be also an important factor for the expression of the biological function of HGF. 相似文献

A Multivariate analysis was done in all patients who developed post operative ARF, during the period 1990–1995 to determine the etiological spectrum and to identify various variables affecting the outcome. Of 140 patients (110 operated at SGPGI and 30 operated outside) 116 underwent elective surgery. The different types of surgery leading to ARF were urosurgery (3.5%), open heart surgery (32.9%), gastrosurgery (16.4%), pancreatic surgery (9.3%), obstetrical surgery (3.6%) and others (2.8%). The incidence of ARF in SGPGI patients was highest in pancreatic surgery group (8.2%) followed by open heart surgery (3%). The different etiological factors responsible for ARF were perioperative hypotension (67.1%), sepsis (63.6%) and exposure to nephrotoxic drugs (29.3%). Sixty-four patients (45.7%) required dialysis. The overall mortality was 45% The mortality was highest in patients who underwent open heart surgery (89.1%) followed by pancreatic surgery (84.6%). The factors associated with high mortality, other than the type of surgery, were preoperative hypotension (p <0.05), oliguria (p <0.01), need for dialysis (p <0.05) and multiorgan failure (p <0.001). AM following emergency surgery had poor outcome, though not statistically significant. Perioperative sepsis (p <0.05) and preoperative use of aminoglycoside (p <0.05) were significantly higher in patients operated outside SGPGI. This was associated with higher incidence of ARF. Thus we conclude that presence of multiorgan failure, oligoanuria, preoperative hypotension and need far dialysis are poor prognostic markers in ARF following surgery. 相似文献

We report a 67-year-old man with acute uric acid nephropathy, secondary to spontaneous tumor lysis syndrome, that presented itself as a huge intra-abdominal tumor that led to acute renal failure, hyperuricemia, and azotemia. Initial finding of hydronephrosis detected by ultrasonography led us to believe that the azotemia and decreasing amount of urine resulted from obstructive uropathy, a common complication of malignancy, caused by either a direct renal invasion or a urinary outflow tract compression because of a tumor mass effect. However, clinical observations and the response to therapeutic intervention confirmed the diagnosis of spontaneous tumor lysis syndrome, which is a rare cause of acute uric acid nephropathy. 相似文献

Ginsenoside-Rd has been proved to decrease the severity of renal injury induced by cisplatin, in which proximal urinaferous tubules represent the main site of injury. When ginsenoside-Rd was given orally at a dose of 1 or 5 mg/kg body weight/day for 30 consecutive days prior to cisplatin injection, the activities of the antioxidation enzymes superoxide dismutase and catalase were higher, while malondialdehyde levels in serum and renal tissue were lower in the treated rats than in the controls. The levels of urea nitrogen and creatinine in serum were decreased in rats given ginsenoside-Rd. Decreased urinary levels of glucose, sodium and potassium reflected a protective action against the renal dysfunction caused by cisplatin. In addition, it was demonstrated that ginsenoside-Rd affected cultured proximal tubule cells exposed to cisplatin. 相似文献

We encountered a 53-year-old man associated with acute renal failure caused by Waldenström's macroglobulinemia and type I cryoglobulinemia. Treatment with prednisolone and cyclophosphamide induced a rapid recovery from acute renal failure. Renal histology revealed endocapillary proliferation and lobular formation with scattered subendothelial, amorphous and periodic acid-Schiff (PAS)-positive materials in the glomerular capillaries which were positive for IgM on immunofluorescence study. Although the exact mechanism for pathophysiology of acute renal failure remains unknown, treatment with prednisolone and cyclophosphamide could induce a rapid recovery from acute renal failure accompanied by Waldenström's macroglobulinemia and type I cryoglobulinemia. 相似文献

It is commonly believed that religion has no influence on medication compliance. We present a case in which belief in faith healing led to discontinuation of immunosuppressive medications after renal transplantation. Conflict occurs when patients believe they are healed but experience continued illness. Religious and spiritual beliefs should be assessed pre-and post-transplant, and efforts made to encourage medication compliance. 相似文献

Melatonin, the pineal hormone with antioxidative properties was administered to rats with glycerol-induced myoglobinuric acute renal failure (Gly-ARF). This model is characterized by acute tubular necrosis mediated by heme-iron oxidative stress. Rats received melatonin (20 mg/kg) concomitant and 3 h after glycerol injection. Gly-ARF rats showed at 24 h a 78% reduction in glomerular filtration rate, whereas this decrement was significantly reduced to 35% in the melatonin treated Gly-ARF rats. Tubular function evaluated by tubular reabsorption of sodium and lithium was also preserved in melatonin treated rats. The histologic analysis revealed extensive cortical tubular necrosis that was significantly reduced by melatonin treatment. The renal concentration of malondialdehyde (MDA) was increased 6 h after glycerol injection in Gly-ARF and this elevation was prevented when melatonin was administered. Renal concentration of reduced glutathione (GSH) was decreased at 6 h in Gly-ARF and melatonin did not reverse this decrease. It was concluded that melatonin administration attenuated the renal injury in the glycerol model of acute renal failure and reduced kidney oxidative stress through a GSH-independent mechanism. 相似文献

Acute renal failure (ARF) is a well-documented but infrequent complication in patients treated with low-molecular weight dextran (LMWD). We herein report 3 cases of oliguric ARF following the administration of dextran-40. One case developed ARF totally after 1.200 g of LMWD administration. In contrast, two cases having increased serum creatinine developed oliguria despite the acceptable therapeutic doses (totally 450 and 650 g). Contrast media was also co-administered in these patients. Plasma exchange (PE), double filtration plasmapheresis (DFPP), or continuous hemodiafiltration (CHDF) but not hemodialysis (HD) reduced circulating dextran concentrations by 35–44% during a single session. All patients completely recovered from ARF by 14–32 days after the treatment. Our cases suggested that radiocontrast could predispose to the development of LMWD-induced ARF especially in patients having pre-existing renal dysfunction. In addition, PE, DFPP and CHDF afforded a beneficial effect for removing accumulated LMWD from the circulation. 相似文献

Acute renal failure in pregnancy is not common in industrialized countries. HELLP syndrome (hemolysis, elevated liver enzyme, and low platelets) was one of the causes of acute renal failure in pregnancy, but renal pathological findings in case of acute renal failure had rarely been reported. We reported an unusual case of HELLP syndrome with acute renal failure requiring renal replacement therapy and which histopathologic findings of kidney biopsy showed mesangial proliferative glomerulonephritis and her renal function completely recovered after immediate artificial abortion, supportive management, transfusion of blood products, and hemodialysis. 相似文献

Background: Achieving “adequacy of dialysis” includes the maintenance of normal serum ionized calcium concentrations and is an important therapeutic goal in the treatment of acute renal failure (ARF). It is unknown whether this goal is best achieved with intermittent or continuous renal replacement therapy. Methods: We compared the effects of continuous veno–venous hemodiafiltration (CVVHDF) and intermittent hemodialysis (IHD) on serum ionized calcium concentrations using daily morning blood tests in 88 consecutive intensive care patients of which half were treated with IHD and half with CRRT. Results: Mean patient age was 54 ± 14 years for IHD and 60 ± 14 years for CVVHDF (NS). However, patients who received CVVHDF were significantly more critically ill (mean APACHE II scores: 24.4 ± 5.1 for IHD vs. 29.2 ± 5.7 for CVVHDF, p<0.003). Before treatment, the mean ionized calcium concentration was 1.177 ± 0.03 mmol/l for IHD and 1.172 ± 0.04 mmol/l for CVVHDF (NS), with abnormal values in 51.6% of IHD patients and in 68% of CVVHDF patients (NS). During treatment, hypocalcemia was significantly more common among CVVHDF patients (24.5% vs. 14.9%; p<0.011) while hypercalcemia was more frequent during IHD (36.1% vs. 25.6%; p<0.019). Conclusions: Abnormal serum ionized calcium concentrations are frequent in ARF patients before and during renal replacement. Once dialytic therapy is applied, CVVHDF is more likely to lower serum calcium concentrations, while IHD is more likely to induce hypercalcemia. Appreciation of these different biochemical effects may assist clinicians in adjusting dialytic therapy in selected patients. 相似文献
