Abstract

Cellular damage and inflammation after ischemia contribute to sustained acute renal failure (ARF). To quantify cellular damage and inflammation in postischemic ARF and identify markers of renal functional outcome, urine specimens from 40 renal allograft recipients, including 30 cadaveric (9 "sustained ARF" and 21 "recovery" subjects) and 10 living donor allografts ("LD"), were analyzed for actin, gamma-glutamyl transpeptidase (GGTP), lactate dehydrogenase (LDH), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and interleukin-8 (IL-8) during the first posttransplant week. On day 0, urinary actin, GGTP, IL-6, and IL-8 were elevated in recipients destined to have sustained ARF compared with those destined to recover. Median values per gram of urine creatinine in the sustained ARF, recovery, and LD groups were 263.9, 0.0, and 0.0 microg for actin; 5000.0, 892.9, and 5555.6 U for GGTP; 193.1, 27.2, and 10.5 ng for IL-6; and 382.0, 17.8, and 18.5 ng for IL-8, respectively. In contrast, urinary LDH and TNF-alpha increased in recipients with recovering function compared with those who had sustained ARF. The corresponding median values were 36.7 and 16.3 U (recovery versus sustained ARF) for LDH, and 18.4 and 7.6 ng (LD ve...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
