The clinical and morphologic findings of three patients with metabolic acidosis, methylmalonic aciduria, and homocystinuria are presented. The clinical evolution of the patients was similar and was characterized in the first weeks of life by failure to thrive, hypotonia, and lethargy associated with pancytopenia and hepatic dysfunction, eventually progressing to severe respiratory insufficiency and renal failure consistent with a hemolytic-uremic syndrome. The patients died at 40, 45, and 75 days of age. Biochemical analyses and complementation studies revealed a congenital anomaly of vitamin B12 metabolism (cobalamin C disease). Postmortem morphologic findings in all three cases were dominated by a thrombotic microangiopathy of the kidneys and lungs, diffuse hepatic steatosis, and megaloblastic changes in the bone marrow. A severe gastritis with striking cystic dysplastic mucosal changes and total absence of parietal and chief cells was a consistent finding in all three cases, the rest of the gastrointestinal tract appearing essentially normal. Cobalamin C disease is an intracellular defect of cobalamin metabolism with possible recessive inheritance that can result in multiorgan failure early in life, with a thrombotic microangiopathy and unusual changes in the gastric mucosa.

A previously healthy 35-year-old woman was seen at 37 weeks' gestation with a 10-day history of fever, vomiting, diarrhea and malaise. Serum laboratory findings included elevation of serum bilirubin and AST, prolongation of serum prothrombin time and a positive monospot. A tentative diagnosis of acute fatty liver of pregnancy was made, and a healthy male infant was delivered by emergency cesarean section because of fetal distress. Over the subsequent 3 days, acute progressive oliguric renal failure, disseminated intravascular coagulation, hypoglycemia requiring intravenous dextrose infusion and pancreatitis developed; her mental status progressed to stage III encephalopathy. Quantitative computed tomography estimated the liver volume to be 770 cm3. The decision to proceed with orthotopic liver transplantation was made on the basis of progressive clinical deterioration despite aggressive support and because of her small liver size. After transplant, the patient's multisystem failure rapidly reversed. Histopathological examination of the native liver demonstrated predominantly zone 3 microvesicular steatosis with characteristic ultrastructural changes consistent with acute fatty liver of pregnancy. Southern blot analysis for Epstein-Barr virus DNA was negative. We conclude that orthotopic liver transplantation should be considered for the small group of patients with fulminant hepatic failure associated with acute fatty liver of pregnancy who manifest signs of irreversible liver failure despite delivery of the fetus and aggresive supportive care.

3 cases of suicide due to ingestion of 150, 200 and 4 gr. of paraquat, respectively, are presented. Two of them were brothers and agricultural industrialists, the other one was a farmer. The first two cases died 16 and 10 hours after intake. The farmer died 21 days after ingestion. All of them had progressive hypoxemia and renal failure the two brothers had heart conduction system glycemia (23 mg/dl) a few hours after ingestion. The postmortem study showed edema, hemorrhage and congestion of the lungs, alveolitis, fibrosis and lobar atelectasia; renal tubular necrosis adrenal necrosis; colestasia; hepatic steatosis focal miocarditis. The clinical evolution, particularly short in the first two patients, is commented on, as well as the post-mortem findings, comparing them with those described in the literature. Finally, due to the high toxicity of this herbicide, we insist in prompt transport to herbicide, we insist in prompt transport to the hospital in order to apply early treatment.

A 38-year-old female was admitted to our hospital because of dyspnea. The diagnosis of total lipodystrophy was made by following findings: (1) gaunt appearance; (2) insulin-resistant diabetes mellitus; (3) hyperlipidemia; (4) fatty liver. Chest X-ray demonstrated cardiomegaly, pulmonary edema and pleural effusion. Echocardiogram was characterized by left ventricular hypertrophy with asymmetrical septal hypertrophy and left ventricular dysfunction. Renal biopsy revealed focal glomerulosclerosis. We reported a patient with total lipodystrophy combined with heart failure and renal failure, which have been rarely associated with the disease.

Hepatic steatosis and steatonecrosis occur in nonalcoholic individuals, usually in a setting of obesity, type II diabetes mellitus, and after jejunoileal bypass. We propose an hypothesis for the pathogenesis of these hepatic lesions based on an observation in peritoneal dialysis patients. Hepatic histology was examined at autopsy in 11 patients with type I diabetes mellitus and renal failure who had received i.p. insulin in conjunction with continuous ambulatory peritoneal dialysis (CAPD). Steatosis in a unique subcapsular distribution occurred in 10 of 11 patients treated with i.p. insulin and in 0 of 9 controls receiving CAPD without insulin. Three of the 11 had steatonecrosis, 2 of whom had Mallory bodies. We suggest that insulin has an important role in the pathogenesis of steatosis and steatonecrosis. In CAPD patients the lesions occurred only under the capsule where concentrations of insulin are high secondary to its i.p. administration. In obese patients the lesions occur throughout the liver where insulin concentrations are high because of elevated levels in the portal vein. Free fatty acids (FFA) are oxidized in the liver by a pathway that is blocked by insulin. In the presence of insulin, FFA are preferentially esterified into triglycerides which accumulate in large quantities leading to steatosis; small amounts of FFA escaping local control may lead to membrane injury and steatonecrosis. Steatosis and/or steatonecrosis will occur when there is insulin secretion sufficient to block FFA oxidation but not sufficient to block FFA mobilization from adipose tissue.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute renal failure is a most challenging clinical problem when it occurs in pregnancy. It requires an understanding of the normal physiology of the kidney in pregnancy and the natural history of different underlying renal diseases when pregnancy occurs. Because patients with chronic renal disease may present with worsening proteinuria, hypertension, and renal function, these disorders must be excluded from those conditions that cause acute deterioration of renal failure in otherwise normal women during pregnancy. As in all patients who develop acute renal failure, prerenal and obstructive causes must be excluded. Particularly important causes of prerenal azotemia in pregnancy include hyperemesis gravidarum and uterine hemorrhage, especially if it is unsuspected as in abruptio placentae. Infectious causes of acute renal failure in the pregnant woman include acute pyelonephritis and septic abortion. The clinical presentation of both these conditions should be apparent, and appropriate diagnosis and treatment can then be promptly instituted. Renal cortical necrosis is another cause of renal failure that occurs more frequently in pregnancy, and it must be differentiated from the many causes of acute tubular necrosis that may be associated with pregnancy. Those conditions that cause renal failure unique to pregnancy must always be considered when renal function deteriorates in the last trimester or the postpartum period. Severe preeclampsia, acute fatty liver of pregnancy, and idiopathic postpartum acute renal failure may all present similar complications, but the approach to each of these clinical disorders must be individualized. By understanding the causes of renal functional deterioration in pregnancy, a logical differential diagnosis can be established, allowing appropriate therapeutic decisions to preserve both maternal and fetal well-being.

A case is reported of acute fatty liver of pregnancy with maternal and foetal survival inspite of jaundice, encephalopathy, renal failure, gastro-intestinal haemorrhage and serious coagulation problems. The acute fatty liver is a rare disease of unknown aetiology which occurs during the third trimester of pregnancy. Early diagnosis based on liver biopsy obtained by the transjugular route, immediate delivery of the foetus and intensive care improve an otherwise fatal prognosis.

We treated a patient with idiopathic fatty liver of pregnancy and a subsequent uncomplicated pregnancy. She experienced general fatigue, nausea, vomiting and jaundice, and renal failure occurred in the third trimester of her first pregnancy. Liver biopsy revealed swollen hepatocytes with microvesicular changes in the cytoplasm. A diagnosis of idiopathic fatty liver of pregnancy was made. Following delivery of a dead fetus, she recovered completely and was discharged on the 30th hospital day. Eighteen months later, she became pregnant again and was delivered of a healthy male baby in the 39th week of gestation. Total bilirubin and transaminase levels were normal, and renal function tests revealed no significant changes during the course of the pregnancy. However, cholinesterase activity increased progressively from the 7th month, thereby suggesting a predisposition to idiopathic fatty liver of pregnancy.

We evaluated amount and composition of amino acids in supplementation of hyperalimentation from the standpoint of whether it may improve nutrition and/or reduce the indexes of uremia such as BUN. Rats with established uremia, by 5/6 nephrectomy, were treated with various isocaloric solutions containing different amount of essential amino acids and histidine (EAA) or standard amino acids (SAA) which were formulated to provide Cal/N ratios of 300, 600, and 900. The BUN was lower and the nutritional index was better in rats infused with EAA compared with those administrated SAA, while severe distortion of plasma amino acid concentration, hyperammonemia, and fatty liver were observed at the Cal/N 300 condition. Rats infused with SAA gained positive nitrogen balance at the condition of Cal/N 300; however, plasma amino acid distortion was still observed. These results indicate that administration of EAA alone for treatment of renal failure needs high-calorie and low-nitrogen conditions such as Cal/N 600 for avoiding complications. Administration of standard amino acid solution is safe and nutritionally effective in the Cal/N 300 condition, but there are a few problems concerning nitrogen availability and plasma amino acid pattern.
