Abstract

Serum creatinine (sCr) levels of >1.5mg/dL or >130 ummol/L at 1 year after renal transplantation were strongly predictive of long-term allograft survival. A Tc-99m MAG3 study with a Hilson's perfusion index (PI) is routinely performed on day 3 post-transplantation at Princess Alexandra Hospital, Australia. The predictive power of day 3 post-transplantation Hilson's PI for long-term sCr levels; and early sCr levels (at 1 or 3 months) to predict sCr levels at 12 months post-transplantation were studied. One hundred eight patients receiving renal transplantation from April 2001 to March 2002 were retrospectively analyzed. sCr levels at 1, 3, and12 months, and 5 years after renal transplantation were recorded and compared with the day 3 post-transplantation Hilson's PI. Accuracy of 72% to 74%, and 90% sensitivity were recorded between Hilson's PIs and sCr levels up to 12-month post-transplantation. Spearman's correlation shows a significant relationship (R = 0.32-0.39, P = 0.00002-0.003). However, the association seems to have low specificity. A significant relationship was found for early sCr levels (at 1 or 3 months) to predict sCr levels at 12-month post-transplantation, with a Spearman correlation coefficient (R = 0.68-0.85, P ...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.
