Minimum immunobiology packages may improve kidney transplant safety and equity in low- and middle-income settings.

This narrative review assessed kidney transplantation strategies within low- and middle-income settings, with a specific focus on Sri Lanka. The analysis compared a minimum immunobiology package against published ranges from similar middle-income programmes. This package included sensitisation, antibody screening using PRA and Zora assays, single-antigen bead testing, donor-specific antibody interpretation, virtual crossmatch, and CDC crossmatch. The review did not report a specific sample size or follow-up duration for the primary data synthesis.

The primary outcomes of interest were safer kidney transplantation, improved equity, and better graft outcomes. Secondary outcomes included unexpected early rejection and the reliability of immunological risk assessment. The review noted that prioritising actionable, scalable immunobiology components is relevant for these settings. However, the study did not report specific adverse events, serious adverse events, discontinuations, or tolerability data for the interventions described.

Significant limitations were identified, including major constraints in real-time transplant immunobiology support, increasing recipient sensitisation, prolonged dialysis vintage, and a growing deceased-donor programme. The authors caution that over-reliance on any single assay can be misleading. Consequently, the evidence regarding the efficacy of this package remains observational and subject to these contextual challenges.

Practice relevance is directed toward implementing scalable immunobiology components in resource-limited environments. Clinicians should interpret findings with caution given the lack of randomized data and the specific challenges of the Sri Lankan context. The review highlights the need for robust support systems to mitigate risks associated with increasing sensitisation and donor scarcity.
