Early Results of Pilot Study Using Hepatitis C Virus (HCV) Positive Kidneys to Transplant HCV Infected Patients with End-Stage Renal Disease Allowing for Successful Interferon-Free Direct Acting Antiviral Therapy after Transplantation.

INTRODUCTION: Hepatitis C virus (HCV) infection in kidney transplant (KTX) patients reduces long-term patient and graft survival. Direct-acting antivirals (DAA) are > 90% effective in achieving sustained viral response (SVR); however, DAAs are not routinely available to patients with end-stage renal disease (ESRD). The University of Utah Transplant Program developed a protocol to allow HCV-positive potential KTX recipients to accept HCV-positive donors' kidneys. Three months after successful KTX, they were eligible for DAA therapy. METHODS: HCV-positive patients approved for KTX by the University of Utah Transplant Selection Committee were eligible to be enrolled in this study. Patients consented for the use of HCV-positive donor organs. Three to six months after successful KTX, these patients were treated for HCV with interferon-free direct-acting antiviral regimens according to viral genotype and prior treatment experience. RESULTS: Between 2014-2015, 12 HCV-positive patients were listed for KTX. Eight patients were kidney only eligible, seven patients received HCV-positive deceased donor kidneys, and one received an HCV-negative organ. Currently, six patients have completed treatment, all have achieved sustained viral response (SVR), and one patient is currently awaiting treatment. All seven patients have functioning kidney grafts. Wait time for KTX was reduced amongst all blood groups from an average of 1,350 days to only 65 days. CONCLUSIONS: HCV-positive patients with ESRD can successfully receive an HCV-positive donor's kidney. Once transplanted, these patients can receive DAA therapy and achieve SVR. Use of HCV-positive organs reduced time on the waitlist by greater than three years and expanded the donor organ pool.

Perceived benefits of a transplant surgery experience to general surgery residency training.

OBJECTIVES: The benefit of a solid-organ transplant experience during general surgical training has been questioned recently. In 2008, in response to an American Board of Surgery (ABS) directive, a survey was conducted by the Association of Program Directors in Surgery (APDS) in coordination with the American Society of Transplant Surgeons (ASTS) to determine the perceived value of a transplant surgery rotation to program directors and residents. With the aim of providing additional insight, we conducted a separate study, independent of the ABS and ASTS, to ascertain resident perceptions regarding the specific skill sets that they acquire during their transplant surgery rotations and their applicability to other surgical subspecialties. METHODS: A preliminary, 51-item, web-based questionnaire was completed by 69.6% of residents in nationally accredited general surgery programs who accessed the survey. The results were examined using appropriate statistical methods to determine associations between answers. RESULTS: Although only 16.6% of participants responded that they were considering a career in transplantation, 63.4% answered that the skill sets acquired during this rotation would assist them in their surgical careers regardless of their chosen specialty. Most (65.5%) respondents answered that the techniques learned were directly applicable to other specialties, such as vascular, urologic, trauma, and hepatobiliary surgery. Free response questions indicated that the most common criticisms of this rotation were the limited amount of operative participation, lack of teaching by attendings, and lifestyle limitations. CONCLUSIONS: The results of this study indicate that surgery residents are conflicted regarding their transplant surgery experience but regard it as a beneficial addition to their training. Most respondents indicated also that these skills were transferable directly to other surgical specialties.

A real-time, telemetric method for continuous measurement of portal pressures.

The ability to longitudinally monitor portal and splanchnic pressures would greatly enhance the understanding of acute and chronic liver disease by helping to assess the immediate and long-term impact of therapeutic manipulations. However, a technique for measuring portal pressures in the ambulatory setting is not currently available. To overcome this difficulty, we utilized an approach that involved the implantation of a miniature telemetric device, equipped with a specially-designed pressure transmission catheter, into the spleen of an anesthetized mouse. Using this approach, portal pressures were measured continuously over 5 d in conscious, unrestrained animals, the availability of which will help facilitate studies of the portal circulation requiring long-term stability.
