RESUMO

Selecting a kidney for living donor nephrectomy is driven by the tenet that donors are left with the higher functioning kidney. Traditionally, the left kidney is used because it has a longer renal vein, which aids anastamosis, and has an easier surgical approach. Anomalous left renal vasculature is not considered a contraindication to living donor nephrectomy. In the case of duplicated inferior vena cava, no specific considerations have been reported. We present a 42-year-old patient with infrarenal duplication of the vena cava who underwent laparoscopic living donor nephrectomy. His postoperative course was complicated by painful scrotal swelling necessitating multiple emergency room visits. Ultrasonography revealed bilateral hydroceles 5 weeks after surgery, which resolved with the use of a scrotal sling. Intraoperative ligation of a visibly dilated left gonadal vein was the likely etiology. Careful consideration should be taken in living donor nephrectomy in patients with duplication of inferior vena cava.

RESUMO

OBJECTIVE: We performed single-center outcome comparison of pediatric recipients who underwent liver transplantation for either genetic or metabolic disease including the clinical impact of using heterozygote parents as living donors. MATERIALS AND METHODS: Pediatric liver transplant recipients from September 2007 to December 2010 were included. Patients were separated into 2 categories by etiology of liver disease: (1) genetic or metabolic liver disease (G/M) and (2) nongenetic or metabolic liver disease (non-G/M), which included all other remaining etiologies combined. Patient demographics, recipient and donor characteristics, graft type, operative data, recipient complications, allograft and patient survival were analyzed. RESULTS: Forty liver transplants were performed on 40 patients; 18 were transplanted for G/M; mean waiting time was 101 days for G/M group and 57 days for non-G/M group; 9 patients were listed as status 1, 5 were granted PELD/MELD exceptions; the overall mean PELD/MELD score was 21. Four G/M patients had hepatocellular carcinoma in the explant without microvascular invasion. Overall complications requiring either surgery or interventional radiology occurred in 14 patients-G/M (n = 5); CMV viremia was seen in 11 patients (G/M, n = 1); detectable EBV DNA was detectable in 8 patients (G/M, n = 4), acute cellular rejection was seen in 10 (G/M, n = 5), postransplant lymphoproliferative disease occurred in 2 G/M patients; and 1 G/M patient showed significantly improved posttransplant neurologic motor function. Children with G/M who received a living donor liver transplant from heterozygote parents did well without any signs of expressing underlying metabolic disease. Posttransplant graft and patient overall survival at 12 months for G/M and non-G/M was 100%, and at 36 months, 83% and 100%, respectively. CONCLUSION: The majority of children transplanted for either genetic or metabolic disease were status 1 or awarded UNOS exception points. Cadaveric split livers and live donors including obligate heterozygotes resulted in excellent allograft and patient survival outcomes. In metabolic and genetic liver diseases, close follow-up and timely transplantation can preclude malignant spread and prevent disease progression and consequences, as well as reverse neurologic sequelae.

RESUMO

BACKGROUND: A minority of liver transplant (OLT) recipients with hepatitis C virus (HCV) develop fibrosing cholestatic hepatitis (FCH), a severe form of HCV recurrence associated with early graft failure and death. There are few reports of successful salvage strategies. In this retrospective study, we sought to determine the characteristics and outcomes for patients with FCH at our transplant center. METHODS: All cases of HCV-positive OLT recipients from July 2007 through July 2010 were reviewed. Patient demographics, donor characteristics, and the post-OLT clinical course were analyzed. Tacrolimus-based immunosuppression was used. FCH was treated by conversion to cyclosporine A (CsA) and aggressive treatment with pegylated interferon (IFN) alpha2A and ribavirin (RBV). Liver biopsies and HCV RNA were obtained frequently per protocol or for cause. RESULTS: The rate of FCH during the study period was 13.5% (5/37). Of the 5 patients with FCH (4 males, 4 Caucasian), mean age was 51 (± 4.8) years and the Model for End-Stage Liver Disease (MELD) score at listing was 26.6 (± 10). Three of the 5 received liver and kidney (L/K) transplants (60%); the rate of L/K transplant in non-FCH patients was 12.5%. HCV RNA levels ranged from 5 to 6.69 log IU/mL pre-OLT; none were on anti-HCV therapy at the time of OLT. Mean ischemic time was 385 (± 152) minutes; donor age was 34.4 (± 13.7) years. No CMV infections developed postoperatively. Time to histologic HCV recurrence was 2 (± 2.23) months (range, 1-6); FCH occurred at 2.2 (± 2.2) months. Patients were converted from tacrolimus to CsA and treated with IFN and RBV; 2 were changed to consensus IFN. HCV RNA increased post-OLT in all, but responded to therapy in 4 of 5. None of the L/K recipients experienced renal graft rejection during treatment. Four of 5 had clinical and histologic improvement; 1 progressed to cirrhosis with minimal inflammation. One-year patient survival after OLT in this group was 80%. Liver allograft rejection occurred in 60% at 4.7 (± 5.5) months and was treated by CsA and prednisone dosage adjustments. In this cohort of patients undergoing OLT for HCV, FCH occurred early after OLT but responded to aggressive management with conversion from tacrolimus to CsA and treatment with pegylated IFN or consensus IFN/RBV. There was a higher rate of combined L/K transplants in the FCH group compared with the non-FCH group. Liver allograft rejection occurred in 60% of cases, but responded to treatment in all; no renal graft rejection occurred in the 3 with L/K transplants while on IFN. One-year graft and patient survival was 80%. CONCLUSION: Better survival with FCH is possible with early initiation of IFN/RBV therapy with close monitoring of biopsies and viral load, and conversion from tacrolimus to CsA. Treatment can be performed even in L/K transplantation recipients, although it is associated with a higher incidence of treatable liver allograft rejection.

RESUMO

Combined liver kidney transplantation (LKT) can be successfully performed on patients with liver and renal failure; however, outcomes are inferior to liver transplantation alone (OLT). Our aim was to determine the indications for and outcome of LKT and whether patients with longer wait times required more frequent LKT versus OLT alone. We included 18/93 adults who underwent LKT from August 2007 to August 2010 for hepatitis C virus (HCV, n = 7), alcohol (n = 5), nonalcoholic steatohepatitis (n = 2), primary biliary sclerosis, polycystic kidney disease with liver involvement, hepatic adenomatosis, and ischemic hepatitis. Eleven were originally listed for LKT and 7 required listing for-kidney transplantation while awaiting OLT. Eight were on dialysis when first listed and 10 had a low glomerular filtration rate or known kidney disease. The mean calculated Model for End-Stage Liver Disease (MELD) score for LKT was 31.2 ± 3.54. Seven had hepatocellular carcinoma in explants. Two patients had acute cellular kidney rejection that responded to treatment. Recurrence of HCV was documented in 5 patients within 6 months of LKT; 2/5 received HCV therapy (interferon and ribavirin) without renal allograft rejection. One-year liver graft/patient survival was 94% after LKT. One patient died at 6 months post LKT due to severe HCV recurrence. Last mean serum creatinine level was 1.35 ± 0.28 mg/dL for LKT patients. LKT is a safe procedure with favorable outcomes even in patients with a high MELD score. Transplantation of patients with a high MELD score due to regional variations in organ allocation results in additional use of kidneys by OLT patients. Improved organ allocation algorithms in OLT would help to reduce combined transplants, sparing more kidneys.
