Simultaneous heart-kidney transplantation (SHK) remains uncommon in the US. We examined outcomes of SHK compared to heart transplant alone (HTA) and deceased donor kidney transplant (DDKT).Data from OPTN/UNOS heart and kidney data bases were used to identify 16 710 HTA, 263 SHK transplants and 68 833 DDK transplants between 1998 and 2007. Outcomes included patient survival (PS), acute cardiac and renal rejection and renal graft survival (rGS).The adjusted risk of death was 44% lower with SHK compared to HTA. Over half of SHK were performed in cases where pretransplant dialysis was not initiated. In these cases, there was no significant difference in the risk of death between SHK and HTA (HR 1.01; 95% CI 0.67-1.50).Recipients of SHK had worse 1-year rGS and PS and had a higher relative risk of overall renal graft loss compared to DDKT recipients. One-year rates of cardiac (14.5%) and renal (6.5%) rejection were lower in SHK compared to HTA and DDKT, respectively.Recipients of SHK had a lower adjusted risk of death compared to HTA recipients, particularly in patients who required pretransplant dialysis. These data suggest that SHK should be considered in heart transplant candidates with renal failure requiring dialysis, whereas the utility of SHK in cases of renal failure not requiring dialysis warrants further study.

Conclusions: Despite more transplants from older donors and among older recipients, LDKT was associated with superior outcomes compared with SPKT and was coupled with the least wait time and dialysis exposure. LDKT utilization should be considered in all type I diabetics with an available living donor, particularly given the challenges of ongoing organ shortage.

Background-Merkel cell carcinoma (MCC) is a rare skin cancer associated with immunosuppression and the integration of Merkel cell polyomavirus (MCPyV) DNA into the tumor cell genome. Little is known about the natural history of MCPyV infection.

Background/Aims: Gastrointestinal (GI) symptoms in renal transplant recipients may be caused due to mycophenolic acid (MPA) toxicity. Using small bowel capsule endoscopy (SBCE) we examined the impact of conversion from Mycophenolate Mofetil (MMF) to enteric-coated formulation of Mycophenolate Sodium (EC-MPS) given to treat GI mucosal lesions. Methods: Adult kidney-only recipients at least 30 days after transplant, presenting with GI symptoms while receiving MMF completed a Gastrointestinal Symptom Rating Scale (GSRS) questionnaire, underwent SBCE, and had MMF substituted by EC-MPS. After 30 days, GSRS and SBCE were repeated and findings were compared to baseline values. Patients who were still on EC-MPS 6-24 months post-conversion were contacted for completing a follow-up GSRS questionnaire and SBCE. Results: Eighteen out of 23 subjects completed the first part of the study. Subjects' median ages and post-transplant time were 47.5 years old and 4.5 months, respectively. Tacrolimus, MMF and prednisone was the main regimen (94%), with a median MMF dose of 750 mg BID. The average baseline GSRS was 2.99 ± 0.81; it significantly decreased to 2.19 ± 0.8 at 30 days post-conversion. At baseline, 50 had gastric and 89% had small bowel lesions. At 30 days, 29 and 62% of the SBCE were still showing gastric and small bowel lesions, respectively. Of 5 patients in the study extension, 4 had abnormal SBCE findings but have been reporting improvement in their symptoms. Conclusion: Stomach and small bowel mucosal lesions are common in kidney recipients with GI symptoms when treated with MMF. Conversion to EC-MPS for 30 days significantly alleviated the GI symptoms; however, no evident correlation with SBCE findings was found.
