A 64-year-old Japanese male patient with lupus nephritis associated with adult T cell leukemia (ATL) is described. Percutaneous renal biopsy demonstrated findings consistent with membranous lupus nephritis. To our knowledge, this is the first case of lupus nephritis complicated by ATL, suggesting that human T cell leukemia virus type I may be correlated not only to outbreaks of ATL but also to lupus nephritis/systemic lupus erythematosus.

Favorable effects of fish oil concentrate on risk factors for thrombosis in renal allograft recipients.
The incidence of thromboembolic complications in renal allograft recipients is very high. Since fish oil has antithrombotic properties, we administered 18 capsules of fish oil concentrate (1.5 g of eicosapentaenoic acid, EPA, and 0.7 g of docosahexaenoic acid) per day to 14 renal allograft recipients for 6 months. Another group of recipients served as controls. ⋯ Epinephrine-induced platelet aggregation increased significantly in the control group, and this change was significantly different from that of the treated group (almost a null change). At the end of the study, the ratio of the main urinary metabolite of prostacyclin I2/3 to the metabolite of thromboxane A2/3 was significantly higher in the treated group than in the control group. In conclusion, we suggest that fish oil concentrate may favorably affect risk factors for thromboembolic complications in renal allograft recipients.

Five patients who developed acute renal failure due to acute tubular necrosis following multiple hornet (Vespa orientalis) stings are described. All of them had intravascular hemolysis. Evidence for rhabdomyolysis was present in 2 patients. ⋯ Two patients had thrombocytopenia in the absence of disseminated intravascular coagulation. Two patients died of infections while the remaining 3 recovered completely. Acute renal failure following multiple hornet stings appears to result mainly from intravascular hemolysis or rhabdomyolysis although a direct nephrotoxic effect of venom cannot be excluded.

Clearance studies were performed in four groups of male Wistar rats to assess the protective effect of sodium thiosulfate on cisplatin-induced hypomagnesemia. In group I, sodium thiosulfate (400 mg/kg) was injected intraperitoneally once weekly for 3 consecutive weeks. In group II, only cisplatin (2.5 mg/kg) was administered. ⋯ The fractional excretion of magnesium was also higher in group II than in groups I, III, and IV. These differences persisted for the duration of the study. These results suggest that concurrent injections of sodium thiosulfate intraperitoneally or intravenously prevented the hypomagnesemic and the nephrotoxic effects of cisplatin and can be of clinical significance.
