Coagulation factors were measured in 50 patients presenting with acute renal failure on the day of their admission (D1) and seven days later (D7). A number of changes were observed, particularly in those patients with a poor prognosis (decreased platelet counts and plasminogen concentrations and increased factor VIII related antigen concentrations). In the majority of cases it would appear that disseminated intravascular coagulation remains sub-clinical.

The case is presented of a 14-year-old boy in whom influenza B virus infection caused pneumonia, acute renal failure and disseminated intravascular coagulation (DIC). Survival was achieved by prompt treatment of DIC with clotting factors and heparin. DIC should be diligently sought in severe viral infections because appropriate therapy may be life-saving.

Two children suffering from systemic juvenile chronic arthritis (JCA) complicated by acute disseminated intravascular coagulation (DIC) are described. One had a fatal outcome with acute renal failure and cerebral haemorrhage; the other recovered. Early recognition and treatment of the underlying cause - usually an infection - as well as replacement of clotting factors are important in management.

We describe 26 pregnancies in 19 patients with lupus nephritis. There were 4 spontaneous abortions, 2 therapeutic abortions, 4 stillbirths and 1 neonatal death. 10 deliveries were preterm and 2 fetuses were small for gestational age. 8 pregnancies were not accompanied by change of renal symptoms. Mild signs of renal involvement appeared during pregnancy in 4 patients. 6 patients showed an increase in proteinuria already present before pregnancy without renal function deterioration. A moderate worsening of renal function was observed in 3 patients. 4 patients, 3 of whom had an apparent onset of systemic lupus erythematosus during pregnancy, developed anuric acute renal failure after delivery or after late spontaneous abortion. 2 of them died from sepsis and disseminated intravascular coagulation while 2 had complete recovery of renal function. A high rate of complications was observed in patients not adequately treated during pregnancy. Renal biopsy before gestation was not predictive of the outcome of nephropathy during pregnancy, and change of histology in repeated biopsies was frequently observed.

Renal dysfunction secondary to GI disorders may be relatively common in horses. Persistent dehydration of 8-10% of body weight can lead to prerenal azotemia, which may result in renal ischemia and renal disease if uncorrected. Dehydrated azotemic horses with a urine specific gravity less than 1.018 may have renal disease. Urine specific gravity readings greater than 1.025 usually indicate normal kidney function. A urine Na level less than 20 mEq/L and a urine/plasma creatinine ratio greater than or equal to 20:1 indicate prerenal problems. Use of nephrotoxic drugs should be avoided in septicemic or dehydrated horses. Salmonellosis and proximal enteritis often lead to renal complications. Renal disease associated with DIC warrants a poor prognosis. Treatment of acute renal failure is aimed at eliminating the underlying cause and correcting metabolic abnormalities. Use of IV fluids, dopamine, prostaglandin inhibitors, fresh and electrolyte-spiked water ad libitum, water-soluble vitamins and high-P diets is beneficial. Success of therapy should be judged by laboratory results rather than clinical impressions.

This study describes acute renal failure (ARF) following snakebite in humans and the effects of viperide venoms on the renal structure and function in subhuman primates. ARF developed in 45 of 157 patients with a history of snakebite admitted to the hospitals of the Postgraduate Medical Institute, Chandigarh, India. They were studied clinically, hematologically, and in 35 cases, for renal histopathology. All 45 were treated with antibiotics, and 8 received anti-snake venom. Ten cases had bilateral renal cortical necrosis (BRCN), eight of whom died; less severe acute tubular lesions (ATL) occurred in 23 patients, four of whom died (P less than .001). Sepsis was significantly more common with BRCN than ATL (P less than .05). No statistical difference was found between these groups in bleeding incidence, disseminated intravascular coagulation (DIC), hemolysis, or hypotension. Monkeys given lethal doses of viperide venom developed hypotensive shock, DIC, and hemolysis, with significantly reduced serum complement, and died within 24 hours. However, no renal functional changes or lesions were found. Monkeys given sublethal doses of viperide venom showed a significant increase in serum creatinine levels after 48 hours, and renal lesions were observed in a majority of animals. In conclusion, ARF in snakebite victims appears to be multifactorial in origin. Although hypotension, hemolysis, and DIC are likely to be important pathogenetic factors, a direct cytotoxic effect of the venom on the kidney in producing ARF cannot be excluded.

Four elderly patients with salmonella septicaemia complicated by irreversible endotoxic shock and acute renal failure are described. The organism isolated from three of the patients with Salmonella typhimurium, which is not usually invasive; the fourth patient was infected with S. abony. The factors associated with the severe systemic infections are discussed. Clinical and haematological findings suggested disseminated intravascular coagulation, and this was subsequently confirmed histologically in each patient by the identification of haematoxylinophil bodies in the pulmonary and renal microcirculations.

The roles of glomerular functional and morphologic changes were examined in the acute renal failure associated with generalized Shwartzman reaction in postpartum Munich Wistar rats. The susceptibility of postpartum rats to acute deterioration in renal function after a 2-h endotoxin infusion was found to be greater than in virgin litter mates: glomerular filtration rate fell by 93% in the former vs. 24% in the latter group (P less than 0.001). In postpartum rats there were marked changes in platelet count and fibrinogen level (P less than 0.025) compatible with consumption coagulopathy. Renal blood flow and glomerular filtration rate fell from 5.5 +/- 0.9 and 0.74 +/- 0.12 to 2.0 +/- 0.7 and 0.12 +/- 0.01 ml/min, respectively (both P less than 0.001). Blood pressure did not change. Results of glomerular dynamics studies showed decreases in single nephron filtration rate from 28 +/- 7 to 6 +/- 4 nl/min and in glomerular plasma flow rate from 77 +/- 26 to 23 +/- 12 nl/min (both P less than 0.001). Afferent net ultrafiltration pressure fell from 20 +/- 3 to 5 +/- 4 mm Hg due to a fall in glomerular capillary hydraulic pressure from 47 +/- 1 to 29 +/- 5 mm Hg (P less than 0.001). There were four- and twofold increases in afferent and efferent arteriolar resistances, respectively. Less than 20% of glomeruli had evidence of fibrin deposition after 2 h of endotoxin infusion, a time when glomerular filtration rate was reduced by greater than 90%. [1-Sar, 5-Ile, 8-Gly] angiotensin II infusion before endotoxin significantly protected glomerular filtration rate, 62 vs. 7% of control in rats with no preinfusion (P less than 0.01) despite consumption coagulopathy and glomerular fibrin deposition similar to rats without pretreatment. These data suggest that the early deterioration in renal function in the generalized Shwartzman reaction in the postpartum rat is due to major changes in glomerular dynamics induced by neurohumoral agents and that glomerular fibrin deposition plays a lesser pathogenetic role at this time in this disorder. The study does not address the pathogenesis of renal failure in pregnancy nor peripartum renal failure in another species.

Patients with classical heat stroke are different in many ways from those with exertional injury; contrasts included difference in demographic factors, prior general health, in-hospital complications and laboratory abnormalities (lactate, liver enzymes, pH, electrolytes). Severe hyperkalemia, acute renal failure, rhabdomyolysis and disseminated intravascular coagulation often dominate the course of patients with exertional heat stroke but are uncommon in those with classical heat stroke (Table 4). While lactic acidosis is the rule in exertional injury, it is somewhat unusual in patients with classical heat stroke and when above 3 mmoles/L predicts a poor outcome or death. In spite of the advanced age and multiple medical problems of the patients with classical heat stroke, careful attention to early and aggressive cooling and scrutiny for potential complications can result in salvage of most patients.
