    An International Survey of the Diagnosis, Management, and Treatment of Hepatitis C in Patients with End-Stage Renal Disease
    (Başkent Üniversitesi, 2009-12) Araya, Victor; Ortiz, Jorge; Olson, Mira R.; Grewal, Kevin S.; Bingaman, Adam; Zaki, Radi; Stewart, Shelby; Horton, John
    Objectives: Hepatitis C is one of the leading causes of death from liver disease in the United States, and is frequently associated with renal disease. Two major organizations—the American Association for the Study of Liver Disease and the National Kidney Foundation—have published recommendations regarding the treatment of hepatitis C in the presence of chronic kidney disease; however, these guidelines do not always provide the same recommendations. Given the paucity of data on adherence to the current guidelines, a survey was conducted to provide information about the current practices of physicians in comparison to the published guidelines. Materials and Methods: An observational study was conducted via a global survey asking physicians treating patients who had concurrent hepatitis C and chronic kidney disease. Results: The 218 questionnaires collected requested the physician’s subspecialty, the number of transplants performed at the hospital, the usual method of screening for hepatitis C, the preferred route, the indication and frequency of liver biopsy, the use of ribavirin and interferon, the use of hepatitis-C–positive donors in kidney transplant, and consent requirements. Conclusions: Our results showed that many physicians do not follow current recommendations. We argue that a consensus group be formed to set forth guidelines for the management of hepatitis C to optimize outcomes, and improve overall morbidity.

    Horseshoe Kidneys: An Underutilized Resource in Kidney Transplant
    (Başkent Üniversitesi, 2010-03) Zaki, Radi; Ortiz, Jorge; Pontinen, Thomas; Khanmoradi, Kamran; Kumar, Anil; Kudsi, Hussam; Kung, Shiang Cheng; Chewaproug, Daranee
    Objectives: Although the number of patients awaiting renal transplant is rapidly increasing, the donor pool has remained relatively stable. Horseshoe kidneys, a common renal fusion anomaly, can provide a useful solution to the ever-increasing gap between supply and demand. Materials and Methods: These kidneys can be transplanted, en bloc, into a single recipient or divided and transplanted into 2 recipients. Results: We report 2 cases of successful kidney transplants. Conclusions: The first is a split horseshoe kidney, transplanted into a single recipient, and the second, a horseshoe kidney from a donor after cardiac death split and transplanted into a single recipient. The second case is the first reported case of a horseshoe kidney transplant from a donor after cardiac death. We also performed a review of the literature of horseshoe kidneys with the hope of raising awareness of the necessity and promise of such transplants.
