Lung transplantation (LTx) from "extended donor criteria" donors may reduce significantly organ shortage. However, its influence on results remains unclear. In this study, we evaluate retrospectively the results of LTx from donors outside standard criteria: PaO2/FiO2 ratio < 300 mmHg, age over 55 years, and history of smoking > 20 pack-years. ⋯ There were no differences observed in recipients' prevalence of primary graft dysfunction (PGD) grade 3 over first three postoperative days, duration of mechanical ventilation, intensive care and hospital length of stay, prevalence of rejection, and bronchiolitis obliterans syndrome (BOS). 90-day, 1-year, and 5-year survival (Group I vs. II) were also similar: 88.6% vs. 91.7%, 83.2% vs. 84.6%, and 59% vs. 68.2% (log rank P = 0.367). Carefully selected donor lungs from outside the standard acceptability criteria may expand existing donor pool with no detrimental effect on LTx outcome.

Whereas vascularized composite allografts often undergo acute rejections early in the postgraft period, rejection manifesting with severe vascular changes (graft vasculopathy) has only been observed on three occasions in humans. We report a hand-allografted patient who developed severe rejection following discontinuation of the immunosuppressive treatment. ⋯ The observation that graft vasculopathy can affect skin vessels shows that it is amenable to diagnosis with usual skin biopsy as recommended for the follow-up of these allografts. Graft vasculopathy developing in the setting of vascularized composite allografts likely represents chronic rejection due to under-immunosuppression and, if confirmed, should be included in a future update of the Banff classification of vascularized composite allograft rejection.

Deceased donor organ programme is still in infancy in India. Assessing deceased donation potential and identifying barriers to its utilization are required to meet needs of patients with organ failure. Over a 6-month period, we identified and followed all presumed brainstem dead patients secondary to brain damage. ⋯ The number of possible, potential and effective donors per million population per year were 127, 115.7 and 9.5, respectively. The poor conversion rate of 8.2% suggests a huge potential for improvement. Family refusal in majority of cases reflects poor knowledge and thus warrants interventions at community level.

Pediatric heart allocation in Eurotransplant (ET) has evolved over the past decades to better serve patients and improve utilization. Pediatric heart transplants (HT) account for 6% of the annual transplant volume in ET. ⋯ Survival after transplantation improved over the years, and in almost a decade, the 1-year survival went from 83% to 89%, and the 3-year rates increased from 81% to 85%. Improved medical management of heart failure patients and the availability of mechanical support for children have significantly improved the prospects for children on the heart transplant waiting list.
