Vaccination is the most efficient and cost effective intervention to prevent infectious complications in transplantation medicine.

Infectious diseases after solid organ transplantation (SOT) are one of the major complications in transplantation medicine. One of the most important public health interventions to decrease the mortality associated with infections is vaccination. After SOT, the patients are more susceptible to infectious diseases, the present infections more often and with more severe manifestations of them. The response to vaccines with subsequent protection against infectious diseases depends on the function of the immune system.

In terms to when to vaccinate, before SOT the patients have end organ dysfunction and after SOT they have immunosuppression, both have the risk of altering the immune responses to vaccines. It has been documented a variety of seroprotection rates after vaccination in SOT patients, it depends on the type of vaccine, the immunosuppression and the time after transplantation, overall postransplant patients have a worse vaccine response compared to healthy individuals. We should try to vaccinate before SOT, and because it has been documented that antibodies can wane over time or even become undetectable after SOT, for some vaccines you could check serology.

Below are relevant vaccination resources and articles. I am very interested in hearing what you would like to see in an update which can help you in your practice.

Please submit feedback on how vaccination applies TO your practice

Relevant article in Transplantation

Long-term follow-up of humoral immune status in adult lung transplant recipients
van Kessel DA, Hoffman TW, Kwakkel-van Erp JM, et al.  [published online February 14, 2017]. Transplantation. doi: 10.1097/TP.0000000000001685
The authors show long-term immunologic follow up data of 55 lung transplant recipients (median follow up after transplantation 6.6 years), including antibody responses to pneumococcal vaccination.  Their findings demonstrate that humoral immunity remained suppressed over the follow up period, but was most prominent in the first year after lung transplantation. Response to pneumococcal vaccination pre- and post- transplant was also significantly different.

The Immunogenicity of Influenza Virus Vaccine in Solid Organ Transplant Recipients

This article evaluated the seroresponse rate in 68 solid organ transplant recipients after influenza vaccination; this study showed that compared to healthy individuals, SOT patients had lower antibody titers post-vaccination (70% SOTs vs 50% healthy subjects), the magnitude of the rise of antibodies was lower (SOTs 1.5-2.3 fold vs. healthy subjects 8.7-10.4 fold) and there was no benefit after giving a second dose of influenza vaccine

Should Belatacept Be the Centrepiece of Renal Transplantation?
Mar. 10 - Medscape - Belatacept was developed to minimize cardiovascular risk and nephrotoxicity associated with calcineurin inhibitor (CNI)–based immunosuppression. Recently, 7-year data from the Belatacept Evaluation of Nephroprotection and Efficacy as First-line Immunosuppression Trial (BENEFIT), a phase III study comparing belatacept with cyclosporine, have been published. While during the first year of belatacept the risk of acute rejection episodes was elevated, this seemingly had marginal consequences for long-term graft survival and function as well as patient survival.

For organ transplant recipients, skin diseases and risk factors differ by race
Mar. 8 - Medical Express - It's been long recognized that the immunosuppressant drugs patients are prescribed after an organ transplant come with a fair share of dangerous side effects—including squamous cell carcinoma and other types of skin disease. But despite advances to improve skin cancer prevention for these patients, little is known about how skin conditions affect African-American, Asian and Hispanic transplant recipients. That's a problem, considering that more than half of the 120,000 Americans on the waiting list for organs are nonwhite, according to the U.S. Department of Health and Human Services.

People with autism, intellectual disabilities fight bias in transplants
Mar. 3 - The Washington Post - Paul Corby needs a new heart. On that there is no dispute. The same rare disease that killed his father at 27 is destroying his left ventricle. While there is no cure or surgery that might repair the damage, a heart transplant could extend his life considerably. But Corby, who lives in Pottsville, Pa., is autistic, suffers from several psychological conditions and takes 19 medications. When he applied to the transplant program at the University of Pennsylvania in 2011, he was rejected because of his “psychiatric issues, autism, the complexity of the process . . . and the unknown and unpredictable effect of steroids on behavior,” according to the denial letter sent to his mother.

Acute Myocardial Infarction Common in Renal Transplant Recipients
Mar. 3 - Infectious Disease Advisor - Renal transplant recipients (RTRs) are often admitted with acute myocardial infarction (AMI), according to a study published in The American Journal of Cardiology. Sahil Agrawal, MD, from St. Luke's University Health Network in Bethlehem, Pennsylvania, and colleagues examined recent trends in AMI admissions for 9243 RTRs with functioning grafts. Data were compared to those of 160,932 patients with end-stage renal disease without transplantation (ESRD-NRT) and 5,640,851 patients without advanced kidney disease (non-ESRD/RT) admitted with AMI.
