1. H1N1 Vaccine: No Good in Kidney Transplant Recipients? Vaccine Doesn’t Protect Most Patients

During the recent H1N1 pandemic, officials urged vaccination especially for immunocompromised individuals such as those with HIV/AIDS or patients taking immunosuppressive drugs. Between 80% and 95% of healthy adults develop a sufficient immune response after a single H1N1 vaccination, but what about immunosuppressed patients? Susanne Brakemeier (Charite, Berlin, Germany) and colleagues studied the immune responses to the H1N1 vaccine (Pandemrix) in 60 patients (12 female/48 male) taking immunosuppressives and at least six months post transplant. Twenty-two healthy individuals served as controls. Two transplant patients had immune responses to the vaccine before being immunized. Of the remaining 58 patients, only 34.5% mounted a sufficient immune response to protect against the virus, compared with 91% in the control group. 65.5% of transplant patients exhibited no response or a weak response. A subgroup of transplant patients received a booster vaccination; 42% mounted a sufficient immune response. “These data suggest that in renal transplant patients, a single dose of Pandemrix as well as booster vaccination is not sufficient to induce a protective immune response,” the authors concluded. Dr. Brakemeier advocated for studying H1N1 vaccine response rates in transplant patients more thoroughly. In addition, some patients mounted immune responses against their donated organ after being vaccinated, which highlights the need to test the safety of new vaccines in transplant patients.

2. Reimbursement Policies Need Work to Increase Kidney Donation Incentives Fail to Improve Donation Rates

For several years, a number of states have tried to increase opportunities for organ donation by offering tax deductions or credits to reimburse living donors for non-medical expenses related to donation (time away from work, travel and lodging). Caroline Jennette (University of North Carolina Kidney Center) and J. Bradley Layton (University of North Carolina Kidney Center and Gillings School of Global Public Health) investigated whether these policies have influenced living kidney donation. They compared the 15 states that have enacted policies with the 30 states that have not. (States without living kidney donor information were excluded.) Their analysis revealed that states with reimbursement policies have not significantly increased living kidney donation. Rates of living kidney donation increased in all states in recent years, but surprisingly, states with reimbursement policies had a significantly lower rate of increase. “Policymakers and advocates put enormous time and effort into getting legislation introduced and enacted. This research highlights the need to be sure that policies are implemented in a way that achieves the desired goals—in this case, increasing rates of living kidney donors by decreasing the financial burden of organ donation,” said Ms. Jennette.
