The neuropathological findings in six patients who developed neurological signs after the onset of "septic shock" caused by Gram-negative septicaemia are described. The changes in the brains were characteristic of acute haemorrhagic leucoencephalitis, and there was evidence, particularly in the kidneys, of disseminated intravascular coagulation with tubular necrosis and, in some, appearances indistinguishable from membrano-proliferative glomerulonephritis. It is agreed that acute haemorrhagic leucoencephalitis is another manifestation of a generalised Shwartzman reaction, and it is suggested that activation of complement is the final common pathway that produces tissue damage in the brain and kidney.

Acute renal failure of obstetric origin is common among North Indian patients and comprised 72 (22.1%) of 325 patients undergoing dialysis over an 11-year period. Of these, 46 gravidas had developed renal failure following abortion, and 29 cases were due to complications of late pregnancy. The most striking feature of this study was a high incidence of irreversible renal lesions of bilateral diffuse cortical necrosis in early (18.6%) as well as late pregnancy (37.8%). Overall incidence of diffuse cortical necrosis was 25%. In the remainder, acute tubular necrosis was seen in 52 (72.2%), patchy cortical necrosis in 1 (1.4%), and tubular necrosis along with glomerular involvement in 1 patient (1.4%). Pathogenetic factors which contributed to the development of renal failure, either singly or in combination, were loss of blood failure, either singly or in combination, were loss of blood (79.1%), septicemia (31.9%), hypotension due th hemorrhagic and septicemic shock (51.4%), eclamptic toxemia (11.1%), and disseminated intravascular coagulation in 12.5% patients. Infrequent occurrence of disseminated intravascular coagulation in the septic anc eclamptic patients who developed diffuse cortical necrosis was an interesting finding, as was the fact that coagulopathy was more frequently observed in acute tubular necrosis. Late referral, frequent sepsis, and high incidence of bilateral diffuse cortical necrosis contributed significantly to a high mortality (55.3%).

Three units of group A blood were inadvertently administered to a group O recipient during surgery without evidence of hemoglobinemia, hemoglobinuria, hypotension, disseminated intravascular coagulation, acute renal tubular necrosis, or other signs and symptoms of transfusion reaction. The recipient had normal concentrations of IgG, IgA, and IgM as well as complement (C3) prior to transfusion and anti-A agglutinins titered to 64 (titer of 128 by the antiglobulin technic). Seventeen hours following the transfusion, 28 per cent of the circulating red blood cells were group A (equivalent to 475 ml of packed cells); they were eliminated by day 5 without evidence of hemoglobinuria, hemoglobinemia or hyperbilirubinemia. Anti-A titers (antiglobulin) had risen from a posttransfusion low of 4 to 4,096 by day 10. After treatment of serum with 2-mercaptoethanol, however, hemolytic activity which was first noted on day 5 was lost and the antiglobulin titer dropped to 24 which suggested that most of the anti-A produced in response to the transfusion was IgM rather than IgG. The anti-A titer had dropped to essentialyy pretransfusion levels and the majority of anti-A present was IgM by day 91. The recipient suffered no untoward effects from the transfusion and was in good health three months following the transfusion.

Venom from newborn Bothrops asper snakes has higher lethal, hemorrhagic, edema-forming, proteolytic and defibrinating activities than venom from adult B. asper specimens. Electrophoretic analysis confirmed the variation between these venoms. Intramuscular injection of 100 micrograms of venom from newborn specimens in mice induced defibrination, together with moderate increments of serum levels of lactate dehydrogenase, creatine kinase, hemoglobin and total proteins. A conspicuous hemorrhage developed in injected muscle rapidly after envenomation, probably due to a drastic alteration in capillaries and larger blood vessels. Other histological alterations included moderate myonecrosis, lung collapse and prominent renal damage, characterized by tubular necrosis and hyalinization. Polyvalent antivenom effectively neutralized lethal, hemorrhagic and indirect hemolytic activities of newborn B. asper venom, although requiring higher antivenom doses than neutralization of venom from adult B. asper.

We reported 5 patients with renal failure associated with polyarteritis nodosa (PN). In all patients the renal dysfunction became apparent from 2 to 4 weeks after the onset of fever or neuromuscular symptoms with laboratory findings supporting marked inflammatory process and took the course of either acute or rapidly progressive renal failure. The clinical diagnoses on admission were variable; fever of unknown origin, peptic ulcer disease, polyneuritis multiplex, disseminated intravascular coagulation and Buerger's disease. Microscopic examination of the kidneys in 3 by renal biopsy and in 2 by autopsy revealed crescentic glomerulonephritis without immunoglobulin deposit, segmental necrotizing glomerulonephritis, marked inflammatory infiltrate around the glomeruli, granulomatous lesion, tubular necrosis and cortical necrosis other than necrotizing vasculitis. The outcomes were favorable with prednisolone monotherapy in two patients who had biopsy-proven diagnosis and treatment early in the course. Of all PN the prevalence of renal involvement is considered to be about 70%, the prognosis of which has been considered very poor. However it seems possible to alter fatal outcome of this disease by starting treatment with confident histological proof early in the disease process.

Fifty patients of acute renal failure following Viperine snake bite were studied. Oliguria (100%), local swelling (48%) and bleeding tendencies (42%) were the predominant clinical features encountered. Of the 25 patients in whom detailed coagulation studies were done, 24 patients had disseminated intravascular coagulation (DIC) and 1 had primary fibrinolysis. DIC was commoner with Russell's viper bite (62%) in comparison to Echis carinatus bites (40%). Renal histology obtained in 29 cases revealed tubular necrosis (35%), cortical necrosis (24%) tubular degeneration (17%) and glomerular changes (17%). Ballooning of glomerular capillaries (59%), splitting of glomerular basement membrane (40.7%), swelling of endothelial cells (29.6%), and focal proliferation of mesangial cells (17%) were the significant glomerular changes encountered. 20 (40%) patients succumbed, DIC (50%), irreversible shock (30%) and septicaemia (20%) being the immediate causes of death. Development of oliguria within 24 hours of snake bite and cortical necrosis were associated with higher mortality.

Pregnancy-related acute renal failure (ARF) can include reversible tubular necrosis as well as irreversible cortical necrosis. Though pathogenetic mechanism are not fully understood, disseminated intravascular coagulation (DIC) probably plays a primary role. We report 25 cases of pregnancy-related ARF: 13 were associated with preeclampsia or eclampsia and 12 with obstetric complications. The following parameters were studied: partial thromboplastin, prothrombin and thrombin time, fibrinogen, anti-thrombin III and FDP levels, platelet count, whole blood clot lysis time and area, fragmented red cells (schistocytes) in the blood smear, hemoglobin, aptoglobin and LDH concentrations. DIC was scored in arbitrary units ranging from 12 to 36 and related to the clinical picture, renal outcome and the treatment employed. Five patients had irreversible renal damage, while 19 recovered fully; one patient died and no renal histology was available. The DIC score did not seem to have a significant relation to the severity of renal damage.

After oral ingestion of 600 ml of refined petrol a 23-year-old male developed multiple organ failure. Acute renal insufficiency due to nephrotoxic tubular necrosis requiring hemodialysis was a major manifestation. Moreover, respiratory failure, seizures, hemolysis, disseminated intravascular coagulation, liver damage and erosions of mucous membranes occurred. The patient subsequently recovered completely. In spite of the poor absorption from the gastrointestinal tract and the high first-pass effect in the liver, massive petrol intoxication may lead to reversible multisystemic lesions.

The effect on renal hemodynamics of Russell's viper (Vipera russelli siamensis) venom was studied in 8 mongrel dogs. The venom (0.10 mg/kg) was injected i.v. Measurements of general circulation and renal function were carried out over 48 hr. During the initial post-injection period, mean arterial blood pressure, pulse pressure and heart rate decreased. Total peripheral vascular resistance and renal vascular resistance showed a tendency to increase. There was no change in cardiac output. Thereafter the blood pressure and heart rate returned to the control level 2 hr after injection and remained stable throughout the experiment. The cardiac output remained unchanged, but the pulse pressure later increased. Renal blood flow, glomerular filtration rate, renal fraction and the rate of urine flow were decreased 24 hr after venom injection and rose to the control levels at 48 hr. Renal vascular resistance remained relatively increased, while peripheral resistance decreased, at 24 hr. Blood volume was unchanged throughout the 48 hr. Disseminated intravascular coagulation was not observed, although the clotting time was prolonged. Renal histological studies showed no remarkable changes; tubular necrosis was not seen. The renal hemodynamic changes may initially be due to catecholamine release and later to renin - angiotensin activation with renal vasoconstriction.

Because of the importance of the renin-angiotensin system in renal homeostatic mechanisms, the effect of angiotensin administration upon disseminated intravascular coagulation has been studied in rabbits. An infusion of angiotensin II (0.1 mug/kg/min for 2 hours) produced neither histologic abnormalities in the kidneys nor an elevation of creatinine. After an infusion of thrombin (2.0 units/kg/min for 2 hours) only 3 of 10 rabbits, when sacrified 24 hours later, showed histologic lesions comprised of occasional fibrin thrombi and foci of tubular necrosis. Creatinine levels did not rise. In contrast, the combination of angiotensin and thrombin resulted in renal lesions in 12 of 14 animals. Four had frank cortical necrosis, while combinations of tubular necrosis, glomerular thrombosis and segmental glomerular infarction occurred in the others, together with elevated creatinine levels. Blockade of alpha-adrenoreceptors with phenoxybenzamine in 12 animals did not prevent either these histologic changes or creatinine elevation, showing that the effect of angiotensin was independent of alpha-adrenoreceptor stimulation. The synergistic interaction between angiotensin and disseminated intravascular coagulation was not explained by differences in the consumption of plasma fibrinogen but apparently was due to localization of fibrin thrombi within glomerular capillaries by the vasomotor actions of angiotensin, as has previously been shown to occur with alpha-adrenoreceptor simulation. Such a mechanism might contribute to renal glomerular deposition of fibrin in acute ischemic renal failure.
