Background. About 10-20% of pancreas allografts are still lost in the early postoperative period despite the identification of numerous detrimental risk factors that correlate with graft thrombosis.

Methods. A multicenter cohort study including 899 pancreas transplant recipients between 2000 and 2018 was conducted. Early pancreas failure, long-term pancreas, kidney and patient survival were analyzed and adjusted to donor, recipient and perioperative variables using a multivariate cause-specific Cox model stratified to transplant centers.

Results. Pancreas from donors with history of hypertension (6.7%), as well as with high body mass index, were independently associated with an increased risk of pancreas failure within the first 30 post-operative days (respectively, HR= 2.57, 95% CI from 1.35 to 4.89 and HR= 1.11, 95% CI from 1.04 to 1.19). Interaction term between hypertension and BMI was negative. Donor hypertension also impacted long-term pancreas survival (HR= 1.88, 95% CI from 1.13 to 3.12). However, pancreas survival was no more impacted when calculated on post-operative day 31 and longer (HR= 1.22, 95% CI from 0.47 to 3.15). A significantly lower pancreas survival was observed in patients receiving a pancreas from a hypertensive donor without ACEi/ARB treatment compared to ACEi/ARB treatment. (50% vs 14%, p < 0.001). Pancreas survival was identical among non hypertensive donors and hypertensive ones under ACEi/ARB.

Conclusion. Donor hypertension, despite infrequent, was a significant and independent risk factor of pancreas failure. The well-known  pathogenic role of renin-angiotensin-aldosterone system seems to be involved in the genesis of this immediate graft failure.
