Twelve Rhesus monkeys were inoculated intravenously with about 500 000 malaria parasites, Plasmodium knowlesi. Acute hemolysis occurred 5 days later, and all animals died on the 6th or 7th day after inoculation. All organs were gray-green to gray-brown because of deposition of hemoglobin and malaria pigments. This deposition was particularly striking in the lung, brain, abdominal fat and serous surfaces. Microscopic changes indicative of acute hypoxia were found in the liver (centrilobular necrosis) and kidneys (acute tubular necrosis). Terminal intravascular coagulopathy was evidenced by widely distributed, recently formed, fibrin thrombi.

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%).

Histopathological study was made of 12 Merino sheep - five splenectomized and seven intact - experimentally infected with Babesia ovis. Non-purulent encephalitis; initially exudative and subsequently interstitial pneumonia; pericarditis, myocarditis and haemorrhagic endocarditis; centrilobular necrotic hepatitis; hyperplasia of the lymphoreticular system; necrosis and vascular changes in adrenal glands were observed. The kidney was the most severely affected organ, exhibiting acute tubular necrosis typical of kidney shock syndrome. The lesions observed were suggestive of hypovolemic shock culminating in haemorrhagic diathesis owing to consumptive coagulopathy. Additionally, the massive release of catabolites from lysis and necrosis apparently produced endotoxic shock.

We report two cases of acute renal failure induced by sciadopitysin, a type of flavonoid, and review related papers of flavonoid-induced acute nephropathy in the literature. A total of eight patients were studied. The purpose of this report is to alert physicians to consider this cause of acute renal failure with hemolysis, because flavonoids are widely used in the world. All patients initially presented with fever and gastrointestinal upset after the ingestion of a single large dose or long-term small doses. Symptoms that followed were cola-colored urine and jaundice. Elevation of blood nitrogen and serum creatinine lasted for 2 to 9 weeks. Hemolysis (100%), cholestatic hepatitis (50%), and disseminated intravascular coagulopathy (50%) were also noted in flavonoid-induced oliguric acute renal failure patients. All of these patients required hemodialysis and all but one who died completely recovered within 2 to 9 weeks. Renal biopsy was performed and showed acute interstitial nephritis with acute tubular necrosis. Moreover, we first demonstrated multiple polymorphous inclusion bodies within tubular epithelial cells in electron microscopic examinations. The definite pathogenetic mechanism of flavonoid-induced acute nephropathy needs further elucidation.

Viper venom is mainly hemotoxic and causes coagulation disorders. One of the serious complications of viperine bite is renal failure. Forty adult cases of viper bite with systemic envenomation were studied for renal abnormality. Renal involvement was noted in 13 (32.5%) cases, of which eight (61.5%) had primary fibrinogenolysis and five (38.5%) had disseminated intravascular coagulopathy (DIC). Eight cases (61.5%) with renal dysfunction had incoagulable blood, whereas five (38.5%) had mild coagulation abnormality; however, none of the cases with incoagulable blood who received polyvalent anti-snake venom (ASV) within 8 hr of being bitten developed renal abnormality. In the majority of cases (61.5%), renal dysfunction persisted for more than a week longer than coagulation defects despite adequate treatment. Two cases died. Renal biopsy done in three cases with renal dysfunction revealed acute tubular necrosis. We concluded that renal abnormality correlated well with the degree of coagulation abnormality when left untreated due to late arrival at the hospital. Early administration of ASV prevents renal damage however severe the coagulation abnormality. It appears that DIC is not the cause of renal dysfunction in all cases of acute renal failure, and direct toxicity caused by venom could be responsible for renal dysfunction in certain cases.

A 22-year-old female presented with acute promyelocytic leukemia (APL). Treatment with all-trans retinoic acid (ATRA) resulted in a severe exacerbation of the coagulopathy 5 days after its introduction. This was complicated by bone marrow necrosis, parenchymal liver damage and acute tubular necrosis. Temporary cessation of the drug and subsequent dose reduction was effective in controlling the coagulopathy.

A healthy 70-year-old woman who took nimesulide for 5 days, presented 2 weeks later with jaundice for which no other cause was found. Laboratory evidence of coagulopathy, hypoalbuminaemia and hypoglycaemia were present on admission, and liver biopsy showed massive necrosis of hepatocytes and severe inflammatory infiltrate. Despite supportive and corticosteroid treatment, her jaundice deepened and progressive acute renal failure developed, characterized by a 'prerenal' profile changing into irreversible acute tubular necrosis pattern, coma, occult Gram-negative sepsis and death. Although rare, nimesulide-associated hepatotoxicity and nephrotoxicity may occur and should be recognized as early as possible, to ensure immediate drug withdrawal and treatment.

This study reviewed the 18-year experience of acute dialysis in the pediatric intensive care unit, in order to identify factors that could predict outcome, and to determine whether newer modalities of acute dialysis have influenced this outcome. Sixty-six children (ages 1 day to 19 years) received acute dialysis from May 1980 to April 1998. Factors predicting outcome were analyzed using univariate and Cox regression analysis. Modality of dialysis in the first 15 years was exclusively peritoneal dialysis. with a mortality of 63.9%. However, in the last 3 years, with increasing patient numbers, continuous hemodiafiltration (CHDF) was the modality of choice (56.7%), with a mortality of 73.3%. Univariate analysis showed that age <1 year, coma, acute tubular necrosis, disseminated intravascular coagulopathy, assisted ventilation, and hypotension were associated significantly with poor outcome (P<0.05). Cox regression analysis revealed that mortality was significantly higher in patients on mechanical ventilation (RR 5.96, 95% CI 1.82-19.50), or with age <1 year (RR 2.00, 95% CI 1.08-3.73). In conclusion, despite the increasing use of CHDF over the last 3 years, there was no significant improvement in mortality, probably related to the fact that more critically ill patients were dialyzed.

Wolcott-Rallison syndrome is a rare disease presenting with insulin-dependent diabetes mellitus (DM) before 6 months old, skeletal dysplasia after 6 months old, and liver failure. Other manifestations are renal failure, microcephaly, epilepsy, central hypothyroidism, neutropenia, and dental and dermal problems. The cases were 2 patients from 2 different states of Iran (Khoozestan and Fars) who had developed DM before 6 months old. The first one was a 7-month-old infant who was healthy; in the genetic study (screening), autosomal recessive pattern and novel deletion in EIF2AK3 were reported; her sister had died at 5.5 years old due to diabetic ketoacidosis (DKA) that was associated with liver and renal failure. The second patient had developed DKA at 45 days old, which was associated with mild acute tubular necrosis and abnormal coagulation tests at onset clinical presentation, which were then resolved. He was treated with insulin, and at follow-up, the laboratory data are normal; in the genetic study, EIF2AK3 nonsense homozygous mutation was diagnosed. Genetic study of patients with insulin-dependent DM before 6 months old, especially those with DKA and associated with or without other disorders; attention to novel deletion of in EIF2AK3 gene; screening for skeletal dysplasia after 1 year old; and renal, liver, pancreatic, and thyroid function tests are recommended.

Anticoagulation-related nephropathy (ARN) is a significant and underdiagnosed complication in patients who receive anticoagulation therapy. It is characterized by acute kidney injury in the setting of excessive anticoagulation defined as an international normalized ratio > 3.0 in patients treated with warfarin. A definitive diagnosis is made by renal biopsy showing acute tubular necrosis with obstruction of the tubuli by red blood cell casts. However, the evidence shows that ARN can occur during treatment with novel oral anticoagulants as well. Although it has been suggested that antiplatelet therapy, such as aspirin, might contribute to coagulopathy (and therefore the hypothetical risk of ARN), there are no reports of ARN induced by antiplatelet therapy according to our knowledge. It is also reported that glomerular lesions (i.e., kidney disease) represent a risk factor for ARN. We present a case of an 82-year-old man who developed biopsy-proven ARN after the administration of dual antiplatelet therapy with no previous anticoagulation treatment and normal coagulation tests.
