Global Perspective on Kidney Transplantation: Argentina

Racialized and Immigrant Status and the Pursuit of Living Donor Kidney Transplant - a Canadian Cohort Study

Introduction

Both immigrant and racialized status may be associated with the pursuit of living donor kidney transplant (LDKT).

Methods

This study was a secondary analysis of a convenience cross-sectional sample of patients with kidney failure in Toronto, obtained from our "Comprehensive Psychosocial Research Data System" research database. The exposures included racialized, immigrant, and combined immigrant and racialized status (White nonimmigrant, racialized nonimmigrant, White immigrant and racialized immigrant). Outcomes include the following: (i) having spoken about LDKT with others, (ii) having a potential living donor (LD) identified, (iii) having allowed others to share the need for LDKT, (iv) having directly asked a potential donor to be tested, and (v) accept a hypothetical LDKT offer. We assessed the association between exposure and outcomes using univariable, and multivariable binary or multinominal logistic regression (reference: White or White nonimmigrant participants).

Results

Of the 498 participants, 281 (56%) were immigrants; 142 (28%) were African, Caribbean, and Black (ACB); 123 (25%) were Asian; and 233 (47%) were White. Compared to White nonimmigrants, racialized immigrants (relative risk ratio [RRR]: 2.98; 95% confidence interval [CI]: 1.76-5.03) and racialized nonimmigrants (RRR: 2.84; 95% CI: 1.22-6.65) were more likely not to have spoken about LDKT with others (vs. having spoken or planning to do so). Both racialized immigrant (odds ratio [OR]: 4.07; 95% CI: 2.50-6.34), racialized nonimmigrants (OR: 2.68; 95% CI: 1.31-5.51) and White immigrants (OR: 2.68; 95% CI: 1.43-5.05) were more likely not to have a potential LD identified.

Conclusion

Both racialized and immigrant status are associated with less readiness to pursue LDKT. Supporting patients to communicate their need for LDKT may improve equitable access to LDKT.

Impact of acute kidney injury and renal recovery status in deceased donor to kidney transplant outcome: results from the Thai national transplant registry

The influence of acute kidney injury (AKI) and renal recovery in deceased donor (DD) on long-term kidney transplant (KT) outcome has not previously been elucidated in large registry study. Our retrospective cohort study included all DDKT performed in Thailand between 2001 and 2018. Donor data was reviewed case by case. AKI was diagnosed according to the KDIGO criteria. Renal recovery was defined if DD had an improvement in AKI to the normal or lower stage. All outcomes were determined until the end of 2020. This study enrolled 4234 KT recipients from 2198 DD. The KDIGO staging of AKI was as follows: stage 1 for 710 donors (32.3%), stage 2 for 490 donors (22.3%) and stage 3 for 342 donors (15.6%). AKI was partial and complete recovery in 265 (17.2%) and 287 (18.6%) before procurement, respectively. Persistent AKI was revealed in 1906 KT of 990 (45%) DD. The ongoing AKI in DD significantly increases the risk of DGF development in the adjusted model (HR 1.69; 95% CI 1.44-1.99; p < 0.001). KT from DD with AKI and partial/complete recovery was associated with a lower risk of transplant loss (log-rank P = 0.04) and recipient mortality (log-rank P = 0.042) than ongoing AKI. KT from a donor with ongoing stage 3 AKI was associated with a higher risk of all-cause graft loss (HR 1.8; 95% CI 1.12-2.88; p = 0.02) and mortality (HR 2.19; 95% CI 1.09-4.41; p = 0.03) than stage 3 AKI with renal recovery. Persistent AKI, but not recovered AKI, significantly increases the risk of DGF. Utilizing kidneys from donors with improving AKI is generally safe. KT from donors with persistent AKI stage 3 results in a higher risk of transplant failure and recipient mortality. Therefore, meticulous pretransplant evaluation of such kidneys and intensive surveillance after KT is recommended.

Intention to Donate Kidney and Associated Factors Among Students in Bahir Dar University: Application of Theory of Planned Behavior

Background

Kidney donation is the donation of a kidney from a living or dead person to another living person who requires transplantation. The scarcity of kidneys is a great public health concern worldwide, owing to an increase in end-stage renal failure. There is no sufficient evidence regarding the intention to donate kidneys in Ethiopia.

Objective

To assess the intention to donate kidneys and its associated factors among Bahir Dar University students in Ethiopia in 2023 by the application of theory of planned behavior.

Method and Materials

This institution-based cross-sectional study was conducted from March 7 to April 5, 2023. A multistage sampling technique was used to select 630 participants. Self-administered structured questionnaires were used to collect data. Data were entered into Epi-data version 4.6, and exported to the Statistical Package for the Social Sciences (SPSS) version 25 for analysis. Bivariate and multivariate linear regression analyses were performed. Findings with a p-value <0.05 at the 95% confidence interval were considered statistically significant and interpreted by the unstandardized beta (ß) coefficient.

Results

The mean score of intention to donate the kidney was 12.9 ± 4.1 standard deviation. Direct attitude (B = 0.341, 95% CI = 0.265, 0.416), direct subjective norm (B = 0.088, 95% CI = 0.010, 0.167), direct perceived behavioral control (B = 0.353, 95% CI 0.251, 0.455), knowledge (B = 0.417, 95% CI 0.251, 0.583), and previous experience of blood donation (B = 0.915, 95% CI 0.321, 1.510) were factors associated with intention to kidney donation.

Conclusion

The mean score of intention to donate kidneys was 12.9 ± 4.1 SD. Direct attitude, direct subjective norm, direct perceived behavioral control, experience with blood donation, and knowledge of participants were significant factors for the intention to donate kidneys. Therefore, social and behavioral change communication strategies should address these factors in order to increase kidney donation.
