Outcome of kidney transplantation in different diseases
Insights
Patient survival after kidney transplant varies by primary disease, with conditions like nephrotic syndrome offering better outcomes. Graft survival also depends on the underlying pathology, highlighting the need for personalized treatment strategies.
Area of Science:
- Nephrology
- Transplantation Immunology
- Clinical Medicine
Background:
- Kidney transplantation is a critical treatment for end-stage renal disease.
- Patient and graft survival rates are influenced by numerous factors, including the primary kidney disease and patient demographics.
- Understanding these influences is crucial for optimizing transplant outcomes.
Purpose of the Study:
- To analyze patient and graft survival rates following kidney transplantation based on the primary kidney disease.
- To identify specific diseases associated with superior and inferior transplant outcomes.
- To investigate the impact of non-immunologic factors and patient sex on survival.
Main Methods:
- Retrospective analysis of patient and graft survival data at 3-years post-transplant.
- Categorization of survival rates based on primary kidney diseases (e.g., nephrotic syndrome, IgA nephropathy, diabetes mellitus).
- Correlation analysis between patient survival and non-immunologic graft loss; comparison of survival rates between sexes for specific conditions.
Main Results:
- High 3-year patient survival was observed for nephrotic syndrome (98%), renal hypoplasia (98%), and IgA nephropathy (96%).
- Lower patient survival was noted in Goodpasture's syndrome (88%), hypertensive nephrosclerosis (87%), and diabetes mellitus (IDDM/NIDDM, 85-86%).
- Non-immunologic graft loss was significant in hypertensive nephrosclerosis (21%) and diabetes (27%). IgA nephropathy showed the best graft survival (83% cadaver, 95% LRD).
Conclusions:
- Primary kidney disease significantly impacts patient and graft survival post-transplantation.
- Conditions like IgA nephropathy are associated with better graft survival, while diabetes and hypertensive nephrosclerosis present challenges.
- Sex-based differences in survival exist for certain conditions, warranting further investigation.
Abstract:
A. PATIENT SURVIVAL 1. The best cadaver graft patient survival 3-years posttransplant was observed in those whose primary disease was either nephrotic syndrome (98%), renal hypoplasia (98%), renal dysplasia (98%), IgA nephropathy (96%), or medullary cystic disease (97%). The worst survival was in those with Goodpasture's syndrome (88%), hypertensive nephrosclerosis (87%), MPGN (87%), IDDM (86%), and NIDDM (85%). 2. Patient survival correlated inversely with nonimmunologic graft loss. Nonimmunologic graft loss was high in patients with hypertensive nephrosclerosis (21%), polycystic kidney disease (23%), IDDM (27%), and NIDDM (27%). 3. Females with CGN and IDDM had better patient survival than males with the same diseases. The 2-, 3-, and 5-year survivals for females with IDDM were 91%, 89%, and 87% whereas for males, they were 87%, 84%, and 81%, respectively (p = 0.01). For CGN the 2-, 3-, and 5-year survivals were 95%, 94%, and 93% for females and 93%, 91%, and 90% for males (p less than 0.01). Females with Alport's syndrome had lower patient survival rates at 1 year (86%) than males (95%, p = 0.03). B. GRAFT SURVIVAL 1. The best 3-year graft survival was in recipients whose primary pathology was IgA nephropathy with 83% for cadaver grafts and 95% for LRD grafts. This was not secondary to center effects. The worst graft survival at 3 years for cadaver kidney recipients was in those whose primary illness was NIDDM (61%), hypertensive nephrosclerosis (58%), MPGN (59%), and Goodpasture's syndrome (59%).(ABSTRACT TRUNCATED AT 250 WORDS)
