Background-Atheroembolic renal disease (AERD) is caused by showers of cholesterol crystals released by eroded atherosclerotic plaques. Embolization may occur spontaneously or after angiographic/surgical procedures. We sought to determine clinical features and prognostic factors of AERD. Methods and Results-Incident cases of AERD were enrolled at multiple sites and followed up from diagnosis until dialysis and death. Diagnosis was based on clinical suspicion, confirmed by histology or ophthalmoscopy for all spontaneous forms and for most iatrogenic cases. Cox regression was used to model time to dialysis and death as a function of baseline characteristics, AERD presentation (acute/subacute versus chronic renal function decline), and extrarenal manifestations. Three hundred fifty-four subjects were followed up for an average of 2 years. They tended to be male (83%) and elderly (60% Ͼ70 years) and to have cardiovascular diseases (90%) and abnormal renal function at baseline (83%). AERD occurred spontaneously in 23.5% of the cases. During the study, 116 patients required dialysis, and 102 died. Baseline comorbidities, ie, reduced renal function, presence of diabetes, history of heart failure, acute/subacute presentation, and gastrointestinal tract involvement, were significant predictors of event occurrence.

Vibrio vulnificus, a particularly virulent halophilic vibrio, has been isolated from the blood and skin necrotic lesion of a hemodialyzed patient with sepsis. The patient has had exposure of the skin to seawater. Various chronic conditions including renal failure have a great risk for developing septicemia due to V. vulnificus. It is necessary to inform persons with liver diseases or immunocompromising conditions of hazards associated with the consumption of undercooked seafood and seawater exposure.

The authors present a case of Henoch-Schönlein purpura in a young soldier (19 years old) which they consider important for its etiology and the length of its oligoanuric phase. The syndrome followed a Salmonella hirschfeldii infection, and a protracted oligoanuric phase was followed by nephrotic syndrome and selective glomerular proteinuria which lasted for 1 year. The young man recovered after the eradication of the Salmonella. It seems possible that there was an overall anomalous regulation of the ‘lymphoid system of the mucosa’, perhaps dependent on a genetic predisposition.
