The serum concentration of cystatin C has recently been proposed as a better indicator of glomerular filtration rate (GFR) than plasma creatinine. Little is known about cystatin C in critical illness. We assessed serum cystatin C as a marker of renal function in acute renal failure (ARF) and its power in predicting survival of ARF patients. ⋯ Serum cystatin C was as good as plasma creatinine in detecting ARF in intensive care patients. Neither marker was clinically useful in predicting mortality.

Dialysis is difficult for patients who have simultaneous liver and kidney failure. Effective mobilization of ascites is rare, and hypotension is common. Combining repeated paracentesis with continuous renal replacement therapy can achieve effective volume removal with hemodynamic stability, but requires intensive care unit resources. Large amounts of albumin are lost from the body in the drained ascites. Combining ascites reinfusion with hemodialysis is a potential alternative therapy. ⋯ Ascites recirculation with dialysis is a safe and effective therapy for patients with refractory ascites and severe renal failure, which can be carried out in routine inpatient and outpatient settings. Hemodynamic tolerance was good and thrombocytopenia was modest.
