- BACKGROUND: The increasing use of living kidney donors requires knowledge about long-term effects, especially number and causes of donors with end-stage renal disease (ESRD). METHODS: A retrospective data analysis of 1,112 consecutive living kidney donors who underwent nephrectomy from 1965 until 2005 at Sahlgrenska University Hospital. Case reports were sought with help from nephrologists in the region and data from Swedish Registry of Active Uremic Treatment (SRAU). RESULTS: The number of cases with end stage kidney failure among living kidney donors was 6/1112, that is 0.5%. The donors had reached ESRD during the years 2001-2006, that means 36-41 years after start of the living donor program. The donors were 45-89 years old, median 77 years, and five of six were males. Time since donation was 14-27 years, median 20 years, for the donors developing ESRD. The diagnoses were nephrosclerosis (4 cases), postrenal failure (1 case), and renal carcinoma (1 case). The expected incidence for development of ESRD according to incidence in the general population would have been two donors but we found six. However, considering the high age of the donors in this follow up, the age-matched incidence is calculated to be closer to six donors due to higher incidence in the aged. CONCLUSION: In all 0.5% of the donors developed ESRD. Due to high age of the uremic donors, there seems to be no increased incidence.

- Retransplantation (re-TX) is the only available therapy for irreversible liver graft dysfunction. The outcome of a second procedure depends upon several factors, some of which are not defined at the time of the decision to retransplant. This study is an analysis of all re-TX of the liver performed at our unit between January 1995 and January 2004. Among the 474 liver TX were 55 (11.6%) re-TX in 47 patients. We studied (1) diagnosis at first TX; (2) indication for re-TX and time lapse; (3) donor age and cold ischemia time (CIT); (4) duration of operation, peroperative bleeding, and complications; (5) ICU and ward periods; and (6) patient and graft survivals. Patients who underwent re-TX did not differ from those transplanted once with regard to age, gender, or diagnosis. The indications for re-TX were roughly one-third biliary tract complications/chronic rejection, one-third hepatic artery thrombosis, and one-third others, including primary nonfunction, acute rejection, portal vein thrombosis, sepsis, and B/C hepatitis. The re-TX were "urgent" in 29 and "elective" in 26 cases. Complications were common; about half of the patients were reoperated due to bleeding or biliary problems. To date (May 2004), 15 patients have died (12 "urgent" and 3 "elective"), of whom 5 had well functioning grafts. In summary, liver re-TX is a complicated procedure associated with significant mortality and morbidity, but considering that the actual patient group has a poor prognosis without re-TX, the results are nevertheless encouraging.

Successful combined partial auxiliary liver and kidney transplantation in highly sensitized cross-match positive recipients
- 2007
-
In: American journal of transplantation. - 1600-6135. ; 7:1, s. 130-6
-
Journal article (peer-reviewed)abstract
- Combined liver and renal transplantations can be performed against a positive cross-match, indicating that the liver protects the kidney from the harmful HLA antibodies. This led us to the hypothesis that a partial auxiliary liver graft may have a similar protective effect when performed together with the kidney in highly sensitized patients. Seven patients, with broadly reacting HLA antibodies and positive crossmatches, were transplanted with a partial liver and a kidney from the same donor. In one of the cases a living donor was used. We performed lymphocytotoxic and flow cross-matches before and after the transplantation. Cross-matches turned negative after grafting in five of seven cases. The kidney function was excellent, without rejections, during the follow-up (24-60 months) in these patients. In two cases the cross-match remained positive after transplantation, one with a never-functioning renal graft and the other with an early graft failure, probably due to humoral rejection. A simultaneous transplantation of a partial auxiliary liver graft from the same donor, with the sole purpose of protecting the kidney from harmful lymphocytotoxic antibodies, can be performed successfully despite a positive cross-match and may thus be a new option of treatment for highly sensitized patients waiting for a kidney transplant.

Pseudoaneurysm of the hepatic artery following liver transplantation
- 2006
-
In: Transplantation proceedings. - 0041-1345. ; 38:8, s. 2679-82
-
Journal article (peer-reviewed)abstract
- We report 12 cases of pseudoaneurysm hepatic artery (PA) among 825 liver transplantations (OLT) performed between January 1985 and December 2005. In the early period (1985 to 1995), the incidence was 2.6% and in the later period (1996 to 2005), 0.9%. Median time to onset was 39.5 days post-OLT (range 14 days to 5 years). Six patients presented with rupture into the peritoneum (n = 4) or gastrointestinal tract (n = 2), while five patients presented with gastrointestinal bleed due arteriobiliary fistulation with hemobilia. The twelfth PA was found incidentally during retransplantation. PAs were detected with radiological imaging (n = 4), exploratory laparotomy (n = 6), at autopsy (n = 1) or at retransplantation (n = 1). We performed immediate revascularization, after surgical excision was performed in three and endovascular embolization in one patient. In six patients hepatic artery ligation without revascularization was inevitable with subsequent successful retransplantation in four patients. No PA-specific treatment was attempted in two cases due to the poor prognosis or diagnostic ambiguity. In 10 cases microbial pathogens were cultured in the blood, subhepatic abscesses, or from the wall of the hepatic artery. A hepaticojejunostomy was performed for biliary reconstruction in six patients and two had a hepaticojejunostomy conversion due to biliary leak. Survival in the early period (1985 to 1995) was 14%, whereas during the later period (1996 to 2005), the survival increased to 100% with a 4.2-year median follow-up (range 7.4 months to 6.9 years). Infrequently PA complicates OLT, becoming evident primarily after rupture with hemoperitoneum or a gastrointestinal bleed. Early recognition with angiography is important but acute hemorrhage often requires immediate exploration with ligation of the PA, although surgical or endovascular exclusion of the PA followed by revascularization provides a feasible treatment option.

Late mortality in 679 consecutive liver transplant recipients: the Gothenburg liver transplant experience
- 2006
-
In: Transplantation proceedings. - 0041-1345. ; 38:8, s. 2671-2
-
Journal article (peer-reviewed)abstract
- PURPOSE: Liver transplantation (OLT) is an established treatment with excellent early outcome. However, the long-term results are hampered by side effects of immunosuppression, cardiovascular morbidity, recurrent disease, and chronic rejection. We analyzed causes of late death (>/=2 years post-OLT) in 679 consecutive primary recipients in our institution. MATERIALS AND METHODS: A total of 679 primary OLT recipients including those retransplanted within 3 months between January 1985 and August 2005 were identified; 460 (67.7%) patients survived >/=2 years. The indications were cholestatic disease (35.1%), postviral (11.4%), alcoholic (12.9%), fulminant hepatic failure (7.0%), cryptogenic (3.1%), autoimmune hepatitis (4.8%), malignancy (7.7%), and others (18.0%). Sixty three patients (9.3%) died >/=2 years post-OLT. For 51 patients, sufficient records were present to establish the cause of death. RESULTS: Four hundred sixty (67.7%) patients survived >/=2 years. Their median age was 58 years with, 43.7% older than 60 and 11.1% older than 70 years. Sixty three patients (9.3%) died at a median time of 69 +/- 4.8 months post-primary OLT; 49.1% died of malignancy and 13.7% of vascular complications and infectious complications respectively. CONCLUSIONS: Late mortality in our material is mainly due to malignant disease. Compared to other published reports on late mortality, the proportion of malignancy, especially recurrent, as cause of late death is higher. This might reflect a more generous approach toward accepting older patients and a higher proportion of patients with various malignant diseases accepted for OLT.

Journal article (peer-reviewed)abstract
- BACKGROUND: Blood group ABO-incompatible live donor (LD) renal transplantation may provide a significant source of organs. We report the results of our first 14 cases of ABO-incompatible LD renal transplantation using specific anti-A/B antibody (Ab) immunoadsorption (IA) and anti-CD20 monoclonal Ab (mAb) treatment. PATIENTS AND TREATMENT PROTOCOL: Recipients were blood group O (n = 12), A (n = 1) and B (n = 1). Donors were A1 (n = 2), A2 (n = 3), A2B (n = 1) and B (n = 8), and all were secretor positive. Anti-human leukocyte antigen (HLA) Ab panel reactivity was negative in all recipients except one. All recipients were pre-treated with 3 to 6 IA sessions, using A or B carbohydrate antigen columns, until their anti-A1/B RBC panel indirect antiglobulin test (IAT) titers were < or =8. CDC crossmatch was negative in all cases. Recipients received preoperative mycophenolic acid, and steroids/tacrolimus were started at transplantation. No splenectomy was performed. Eight recipients received one dose of anti-CD20 mAb (rituximab, 375 mg/m2) pre-operatively and 11 recipients had postoperative protocol IA. RESULTS: In the initial protocol, anti-CD20 mAbs were used only for recipients receiving A1 grafts. One B graft (HLA-identical donor, 84% panel reactivity) was lost in a severe anti-B Ab-mediated acute rejection. Subsequently, the protocol included anti-CD20 for recipients of both A1 and B grafts and postoperative protocol IA to all recipients. The subsequent 10 grafts had excellent function, giving a total graft survival of 13/14 (observation range 2 to 41 months). At 1 yr, mean serum creatinine was 113 micromol/l (n = 8) and mean glomerular filtration rate was 55 ml/min/1.73 m2 (range 24 to 77). In the remaining five cases, with less than 1 yr follow up, mean serum creatinine was 145 micromol/l at 2 to 9 months follow up. Pre-IA anti-A/B titers were in the range of 2 to 32 (NaCl technique) and 16 to 512 (IAT). More than 90 IA sessions were performed in 14 recipients without any significant side effects. Recipient anti-A/B titers returned after transplantation to pre-IA levels or slightly lower. Postoperative renal biopsies were performed in 10 patients. In the 13 patients with long-term function, one patient experienced cellular rejection (Banff IIB) at 3 months without anti-B titer rise. This rejection was concomitant with low tacrolimus plasma levels and was easily reversed by steroids. In 8 of 10 cases, C4d staining was positive in peritubular capillaries. CONCLUSION: Blood group ABO-incompatible LD renal transplantation using A and B carbohydrate-specific IA and anti-CD20 mAbs has excellent graft survival and function.

Adult ABO-incompatible liver transplantation, using A and B donors

-
Journal article (peer-reviewed)abstract
- BACKGROUND: The longer waiting time for a liver graft in patients with blood group O makes it necessary to expand the donor pool for these patients. This applies in both urgent situations and for elective patients. We report on our experience with ABO-incompatible liver transplantation using A2 and B non-secretor donors here. PATIENTS AND METHODS: Between 1996 and 2005, 12 adult blood group O recipients (seven male/five female) received ABO-incompatible cadaveric liver grafts (10 A2 donors, two B non-secretor donors). The indications were either rapid deterioration of liver function or hepatocellular cancer, in blood group O recipients, where an ABO-identical/compatible graft was not available. Mean recipient age was 54+/-8 (mean+/-SD) yr. All pre-operative CDC crossmatches were negative. The initial immunosuppression was induction therapy with antithymocyte globulin (n = 3), interleukin 2 receptor antagonists (n = 3) or anti-CD20 antibody (rituximab) (n = 1), followed by a tacrolimus-based protocol. Three patients underwent plasmapheresis post-transplantation. Baseline biopsies were taken before or immediately after reperfusion of the graft and after grafting when clinically indicated. No pre-operative plasmapheresis, immunoadsorption or splenectomies were performed. RESULTS: Patient and graft survival was 10/12 (83%) and 8/12 (67%), respectively, with a 6.5-month median follow-up (range 10 days to 109 months). Two patients (B non-secretor grafts) died of multiorgan failure probably because of a poor condition before transplantation. Three patients were retransplanted. Causes of graft loss were bacterial arteritis (n = 1), death with a functioning graft (n = 1) and portal vein thrombosis (n = 2). In one of the patients with portal vein thrombosis, an anti-A titer increase occurred concomitantly, and ABO incompatibility as the cause of the thrombosis cannot be excluded. Seven acute rejections occurred in five patients and all were reversed by steroids or increased tacrolimus dosage. The pre-transplant anti-A titers tested against A1 red blood cells were 1 to 128 (NaCl technique) and 4 to 1024 (indirect antiglobulin technique, IAT); the maximum postoperative titers were 16 to 2048 (NaCl) and 256 to 32,000 (IAT). CONCLUSION: The favorable outcome of A2 to O grafting, with a patient survival of 10/10 and a graft survival of 8/10, makes it possible to also consider this blood group combination in non-urgent situations. The use of non-secretor donor grafts is interesting but has to be further documented. There was no hyperacute rejection or increased rate of rejection. Anti-A/B titer changes seem not to play a significant role in the monitoring of ABO-incompatible liver transplantation.

- INTRODUCTION: The longer waiting time for a liver graft among patients with blood group O makes it necessary to expand the donor pool for these patients. We herein have reported our experience with ABO-incompatible liver transplantation using A(2) donors to blood group O recipients. PATIENTS AND METHODS: Between 1996 to 2005, 10 adult blood group O recipients received 10 A(2) cadaveric grafts. Mean recipient age was 52 +/- 7.7 years (mean +/- SD). The initial immunosuppression was induction with antithymocyte globulin (n = 2), interleukin-2-receptor antagonists (n = 3), or anti-CD20 antibody (rituximab, n = 1), followed by a tacrolimus-based protocol. No preoperative plasmapheresis, immunoadsorption, or splenectomies were performed. RESULTS: Patient and graft survival was 10/10 and 8/10, respectively, at 8.5 months median follow-up (range 10 days to 109 months). Two patients were retransplanted because of bacterial arteritis (n = 1) and portal vein thrombosis (n = 1). The six acute rejections, which occurred in four patients, were all reversed by steroids or increased tacrolimus dosages. The pretransplant anti-A titers against A(1) red blood cells were 1:128 (NaCl technique) and 1:8 to 1024 (IAT technique). The maximum postoperative titers were 1:64 to 4000 (NaCl) and 1:256 to 32000 (IAT). CONCLUSION: The favorable outcome of A(2) to O grafting, with a patient survival of 10/10 and graft survival of 8/10, makes it possible to consider this blood group combination also in nonurgent situations. There was no hyperacute rejection or increased rate of rejections. Anti-A/B titer changes seem to not play a significant role in the monitoring of A(2) to O liver transplantation.

Journal article (peer-reviewed)abstract
- In contrast to focal segmental glomerulosclerosis, which is well known to recur early in a renal graft, there are only few cases described with recurrence of immunoglobulin M (IgM) nephropathy after transplantation. We herein describe a patient with early recurrence of IgM nephropathy. A 15-year-old boy with nephrotic syndrome (IgM nephropathy) proceeding to end-stage renal disease was on dialysis before living related renal transplantation. Native kidneys were not removed. Standard immunosuppression including steroids, tacrolimus, and mycophenolate mofetil yielded initially good graft function with the s-creatinine falling to 73 micromol/L. Proteinuria was present on day 1, increasing to 20 g/L after 3 days. S-creatinine increased to 158 micromol/L and urine production diminished. A graft biopsy showed no rejection or glomerulopathy but protein vacuoles were seen within tubular cells indicating massive proteinuria. Treatment with plasma exchanges, immunoglobulin, and steroids was started. Hemodialysis was necessary. Proteinuria improved to 3.5 g/L, but s-creatinine continued to rise and a second graft biopsy showed vascular rejection (Banff type IIA). The patient was treated with antithymocyte globulin and further plasma exchanges. A single dose of rituximab was given. Five months after transplantation the s-creatinine was 67 micromol/L and there was no proteinuria. In this case early recurrence of nephrotic syndrome occurred on the first posttransplant day in combination with later occurring vascular rejection. Successful treatment included a combination of plasma exchanges, rituximab, immunoglobulin, and antithymocyte globulin.
