Aim: ABO-incompatible (ABOi) kidney transplantation overcomes immunological barrier of blood group incompatibility. There have been very few published experiences of ABOi kidney transplantation from India. We present our single-center experience of the first hundred ABOi kidney transplants.

Material And Methods: This is a single-center retrospective study of consecutive first hundred ABOi kidney transplant with at least 6 months of follow-up.

Results: During the study period (2011-2020), a total of 121 ABOi kidney transplants were performed. Of these, first hundred patients were analyzed. Median follow-up duration was 33 (10-101) months. Mean recipient and donor age were 41.5 ± 13 and 47.68 ± 11.25 years, respectively. Mean HLA mismatch was 4 ± 1.5. Median baseline anti-blood group antibody titer was 128 (2-1024). Most common recipient blood group was O. Patient and death censored graft survival was 93% and 94%, respectively, at median follow-up of 33 months. Biopsy-proven acute rejection (BPAR) rate was 17% with acute antibody-mediated rejection being 3%. Rate of infection was 37%, most common being urinary tract infection.

Conclusion: ABOi kidney transplant patients had acceptable patient and graft survival as well as BPAR rates. With current preconditioning protocol, infection rate was high.

Background: ABO-incompatible kidney transplantation (ABOi-KTx) represents a possible solution to address the shortage of kidney donors. However, these transplants present immunological challenges, particularly when isoagglutinin titers are elevated pretransplant.

Methods: Single-center retrospective study describing clinical and biological outcomes of 8 patients who underwent ABOi-KTx with initial isoagglutinin titers ≥ 1/512.

: ABO-incompatible live-donor kidney transplantation (ABOi-LDKT) has become an established treatment for end-stage renal disease. Non-inferiority in the long-term graft function compared to ABO-compatible live-donor kidney transplantations (ABOc-LDKTs) has been shown. However, the assumed burden due to complications owing to increased immunosuppression inherent to ABOi-LDKTs has not yet been quantified.

Article Synopsis
  • Robot-assisted kidney transplantation (RAKT) is gaining popularity, but there's limited research on its effectiveness for immunologically high-risk patients, particularly those with ABO incompatibility (ABOi), compared to traditional open kidney transplantation (OKT).
  • A study involving 239 living-donor transplants compared 210 ABOi-OKT cases with 29 ABOi-RAKT cases, using statistical methods to ensure valid comparisons and analyze outcomes like acute rejection and graft failure.
  • Results showed similar one- and two-year survival rates and kidney function between RAKT and OKT, but RAKT had longer surgery times and cold ischemic periods, while hospital stays were shorter for RAKT, indicating it is a safe and effective

Article Synopsis
  • ABO-incompatible kidney transplantation (KT) is increasingly used to address organ shortages, but high levels of anti-ABO antibodies can hinder successful transplantation despite existing desensitization methods.
  • Eculizumab was used as an additional treatment to help patients with very high anti-ABO antibodies who did not respond to standard therapies, showing improvements in kidney function and antibody levels after transplant.
  • The study indicates that short-term eculizumab treatment may effectively support ABOi KT patients by maintaining stable kidney function and reducing antibody levels, even in cases previously deemed challenging.

Article Synopsis
  • The study investigates the risk factors for acute antibody-mediated rejection (ABMR) in ABO blood group incompatible kidney transplants (ABO-I), focusing on donor and recipient samples.
  • Researchers analyzed A/B antigen expression in kidney tissues and other blood components from 104 donors and assessed pre-transplant recipient serum samples for antibody levels.
  • They found that while A/B antigen levels in donors did not correlate with ABMR incidence, higher C1q-IgG binding ability in recipients was linked to an increased risk of ABMR, suggesting it may serve as a predictive indicator.
