Five patients requiring dialysis for acute pulmonary edema and uremia from severe renal artery occlusive disease underwent surgical revascularization. Three patients with oliguria had excellent outcomes and remain dialysis-independent as long as twenty-four months following operation (mean serum creatinine 2.0 mg/dl). The two patients who were anuric both had technically successful operations but remained dialysis-dependent. Diagnostic evaluation of the azotemic patient suspected to have renal arterial occlusive disease should include a history and physical examination, urinalysis, renal ultrasound, and duplex scan of the renal arteries. In appropriate patients, arteriography should then be considered if other diagnoses appear unlikely. This algorithm may help identify those patients who might benefit from renal revascularization. It appears that oliguria rather than anuria and the angiographic demonstration of a patent distal vessel and nephrogram suggest a better functional outcome after revascularization. Unfortunately, the response to surgery cannot be reliably predicted and patient selection remains a challenge, but retrieval of renal function can be achieved in some cases even if patients are already being hemodialyzed.

A 44-year-old Spanish woman travelled in Kenya without doing correct malarial prophylaxis. Upon her return to Spain, she suffered from Plasmodium falciparum malaria. She was initially treated with chloroquine for three days, but her state worsened and she was admitted to our intensive care unit. On admission, parasitaemia was 22%. She had hyperpyrexia, obtundation, hypotension, tachycardia, tachypnoea, jaundice, digestive haemorrhage, petechiae in her soles, oliguria with elevation of serum uraemia and creatinine, anaemia, thrombocytopaenia, hypoproteinaemia, hyponatraemia, hypocalcaemia, metabolic acidosis and parameters of disseminated intravascular coagulation. She was given quinine, sulfadoxine-pyrimethamine and clindamycin. An exchange transfusion was performed, during which an acute pulmonary oedema appeared, initially with high pulmonary artery wedge pressure. She required mechanical ventilation for 16 days and haemodialysis for 11 days. She remained in coma and had seizures which required diazepam, phenitoin and thiopentone. She received a total amount of 22 units of packed erythrocytes, 55 of platelets and 15 of plasma. After the first week, she had nosocomial infection due to Escherichia coli, Staphylococcus and Pseudomonas aeruginosa and was treated with the corresponding antibiotics. She cured completely. This case report gives us the possibility of discussing on frequent problems in the prevention and treatment of malaria, and on the treatment of severe, life-threatening malaria in the setting of the intensive care unit.

Hemolytic uremic syndrome (HUS) is a rare condition which most frequently follows gastrointestinal or respiratory infection episodes in young children, but it can also occur in other settings such as the postpartum period and during use of drugs such as oral contraconceptives, immunosuppressors, and antineoplastics. In early pregnancy, however, its frequency is thought to be very low. The authors report a case of a 30-year-old woman who developed HUS early in her first pregnancy. She had persistent aqueous diarrhea from the beginning of the pregnancy. At the 21st week she developed hypertension which in 2 weeks was followed by seizures, oliguria, and acute pulmonary edema despite intensive medical efforts to control her blood pressure. Surgical intervention for fetal delivery was performed. The patient was initially kept on continuous hemodialysis (CVVHD) followed by an alternate-day conventional hemodialysis schedule. A peripheral blood analysis showed a microangiopathic hemolytic anemia with thrombocytopenia; blood coagulation tests were completely normal. A brain CT scan and an abdominal MRI showed no major abnormalities. HUS was confirmed by a percutaneal kidney biopsy, performed at the 21st day of anuria. Techniques for identification of verotoxin-producing E. coli were not available. Renal function did not recover and the patient has been undergoing regular maintenance hemodialysis for a year.

Takayasu arteritis (TA) is a chronic granulomatous inflammatory condition of unknown cause that involves large vessels - particularly the aorta and its branches - such as the carotid, coronary, pulmonary, and renal arteries. The left subclavian artery is the most frequently involved vessel. Stenosis of the renal artery has been reported in 23-31% of the cases and may result in malignant hypertension, ischemic renal disease, decompensated heart failure, and premature death. Involvement of both renal arteries is uncommon. Early onset anuria and acute kidney injury are rare and have been reported only in a few cases in the literature. This report describes the case of a 15-year-old female with constitutional symptoms evolving for a year, combined with headache, nausea, and vomiting, in addition to frequent visits to emergency services and insufficient clinical examination. The patient worsened significantly six months after the onset of symptoms and developed acute pulmonary edema, oliguria, acute kidney injury, and difficult-to-control hypertension, at which point she was admitted for intensive care and hemodialysis. Initial ultrasound examination showed she had normal kidneys and stenosis-free renal arteries. The patient was still anuric after 30 days of hospitalization. A biopsy was performed and revealed her kidneys were normal. Computed tomography angiography scans of the abdominal aorta presented evidence of occlusion of both renal arteries. The patient met the diagnostic criteria for Takayasu arteritis and had a severe complication rarely described in the literature: stenosis of the two renal arteries during the acute stage of ischemic renal disease.
