BACKGROUND: The impact of hepatitis C virus (HCV) infection in renal transplant patients is controversial and there are no data on the outcome of renal transplantation in this sub-group of Irish patients. AIM: To examine the outcome of renal transplantation in patients with hepatitis C. METHODS: We examined the outcome of first grafts from renal transplant patients with hepatitis C antibody positive and compared them to a control group. During this period, 24 HCV positive patients received 33 grafts. All were treated with standard immunosuppression. RESULTS: Graft survival rate was less in the HCV positive cases (p=0.0087). Graft survival at 1 year was 75% in the HCV positive group versus 85% in the HCV negative group, 40% versus 62% at 5 years and 14% compared with 40% at 10 years. Patient survival was similar in both groups (p=0.78). Patient survival at 1 year was 96% versus 94%, 87% versus 80% at 5 years and 70% in both groups at 10 years. CONCLUSION: In the Irish renal transplant population, the presence of hepatitis C antibodies, before or after transplantation is associated with worse long-term graft, but not patient survival.

Renal transplantation performed across a positive crossmatch: a single centre experience.

UNLABELLED: The importance of certain positive crossmatches (CM+) in kidney transplantation remains controversial. Fifty consecutive kidney transplants were performed across a CM+ between Jan. 1990-April 1994. In 19 cases there was an isolated B-cell CM+ (Group I), in 24 an historic T-cell IgM CM+ (Group II) and in 7 an historic T-cell IgG CM+ (Group III). Comparing groups I:II:III: early acute rejection affected 32%, 42%, 57% of grafts; mean serum creatinine at 3 months was 166, 150, 229 umol/l (p < 0.05); 1 yr graft survival was 95 per cent, 96 per cent, 71 per cent (p = 0.09). In group III both graft losses were in the setting of an additional current B-cell CM+. CONCLUSIONS: Transplantation performed in either the presence of an isolated B-cell CM+ or in the presence of an historic T-cell IgM CM+ was associated with acceptable outcomes at 1 yr. An historic T-cell IgG CM+ was confirmed as a contraindication to transplantation in most circumstances, especially when coupled with a current B-cell CM+.

Long term outcome of renal transplantation in the pre cyclosporin era: one centre's experience.

The number of renal transplants has been increasing steadily over the last twenty years. This increase has been associated with a significant improvement in the one year graft and patient survival. However, as survival improves, long term complications are becoming more clinically important. We, therefore, retrospectively reviewed our experience of renal transplantation in 165 patients between January 1970 and December 1980, and describe in detail the complications experienced by those whose grafts functioned for 10 years or longer. The 10 year patient survival rate was 47% and graft survival rate was 30%. The graft survival rate for living related grafts was superior to that of cadaveric grafts. The major cause of mortality in the first year following renal transplantation was infection and in subsequent years, cardiovascular disease predominated. Patients whose grafts functioned for 10 years or more developed a variety of complications including infection, skin cancer and hepatic dysfunction. Clinicians involved in the long term care of the patients need to be aware of these problems and skilled in their management.

Outcomes of adult cadaveric renal transplantation in ireland 1986 to 2001.

BACKGROUND: Since the introduction of renal transplantation in the Republic of Ireland in 1964, the number of transplants performed annually has increased from single figures in the 1960s to the current rate of approximately 130 renal transplants per year. Improvements in graft and patient outcomes have been associated with the introduction of the immunosuppressive agent Cyclosporin (CSA) in the mid 1980s. AIMS: The aim of this study was to examine trends in outcomes and factors that influence outcomes for adult kidney transplantation from 1986 to 2001. METHODS: All adult cadaveric kidney transplantations carried out between 1986 and 2001 were included. We separated the transplanted grafts and patients into four time periods; 1986-1989, 1990-1993, 1994-1997, 1998-2001. Graft and patient survival outcomes were compared for the different periods. RESULTS: The one-year kidney graft survival rate increased from 82% during 1986-1989 to 86% during 1998-2001. Patient survival over the four time periods studied has remained stable at approximately 95% at one year. CONCLUSION: We report a significant improvement in kidney graft outcomes over the past 16 years. Patient survival has remained relatively stable during this period.

Renal transplantation in the elderly--the Irish experience.

BACKGROUND: The aim of this paper was to evaluate patient and kidney graft survival rates in renal transplant recipients and compare the outcomes between the different patient age groups. METHODS: A retrospective review of all adult renal transplants performed at Beaumont Hospital between the years 1986-2001 was carried out. Patients were defined as 'elderly' if they were 65 years of age or older and 'younger' if less than 65 years at the time of transplantation. Patient and transplant graft survival rates were analysed for each age group. RESULTS: Data were analysed on 1462 'younger' patients and 105 'elderly' renal transplant recipients. Estimated patient survival at 1, 5 and 10 years were 96%, 87% and 74% in the younger patient group compared to 85%, 59% and 33% in the elderly group. The adjusted graft survival rates (adjusted for death due to other causes and with a functioning graft in situ) for the younger group were 89%, 77% and 64% at one, five and ten years respectively, while for the elderly group, adjusted one, five and ten year survival rates were 89%, 83% and 70% respectively. CONCLUSIONS: Although the elderly have a shorter life expectancy than the younger population they do benefit from renal transplantation similar to the younger recipients.

Prevalence and predictors of recurrent IgA nephropathy following renal transplantation.

BACKGROUND: IgA nephropathy is a common glomerulonephritis for which there is no effective cure. It may recur after renal transplantation and cause graft loss. AIMS: To determine the prevalence and predict recurrence of IgA disease in transplant recipients. METHODS: A retrospective analysis was performed of all renal allografts in patients with IgA disease attending a National Renal Unit between 1984 and 1995. An immunopathological grading system was devised to assess the severity of disease at initial presentation and each patient was assigned a simple severity index. RESULTS: A total of 42 patients with IgA disease received 44 renal allografts. Biopsies were performed in 21 of the 44 transplants. Recurrence was diagnosed in five grafts (24%) and recurred only in the 'moderate' and 'severe' IgA groups. Recurrence was associated with younger age, glomerular crescents on the original renal biopsy, better donor/recipient HLA matching and greater number of rejections. CONCLUSION: The prevalence of recurrent IgA disease following transplantation in an Irish population is less than that reported at other centres (24% versus 60%). The severity of the original disease and transplant factors may predict recurrence post-transplantation.
