Dual-graft (DG) adult living donor liver transplantation (ALDLT) with ABO-incompatible (ABOi) and ABO-compatible (ABOc) graft combination is associated with high rates of graft survival, with no significant difference for ABOi and ABOc grafts, according to research published online July 31 in the American Journal of Transplantation. Jae Hyun Kwon, M.D., from the University of Ulsan College of Medicine in Seoul, South Korea, and colleagues conducted a retrospective review of medical records of patients who underwent ABOi DG ALDLT between 2008 and 2014. The authors also assessed the graft regeneration rate using computed tomography volumetric analysis. During a mean follow-up of 57.0 ± 22.4 months, the researchers found that the one-, three-, and five-year patient survival rate was 96.4 percent. The rate of graft survival at one-, three-, and five-years was 96.4, 94.2, and 92.0 percent, respectively; ABOc and ABOi grafts did not differ significantly (P = 0.145). No significant differences were seen between ABOc and ABOi grafts in the biliary complication rate (P = 0.195). There was no significant difference in regeneration rates for ABOi and ABOc grafts. "DG ALDLT with ABOi and ABOc graft combination seems to be a feasible option for expanding the donor pool without additional donor risks," the authors write.

Ropinirole, bromocriptine, and piribedil are associated with the highest incidence rates of adverse effects in Parkinson's disease, according to a review published online Sept. 4 in CNS Neuroscience & Therapeutics. Bao-Dong Li, from the Hebei Province Cangzhou Hospital of Integrated Traditional and Western Medicine in China, and colleagues conducted a systematic review to compare the adverse effects of 11 drugs used to treat Parkinson's disease. Data were included from 24 randomized controlled trials. The researchers found that, compared with placebo, the incidence of adverse reactions of ropinirole, rotigotine, entacapone, and sumanirole were higher in terms of nausea. The incidence rates of dyskinesia side effects were highest with ropinirole, while in terms of patients' hallucination, pramipexole was significantly higher. The surface under the cumulative ranking curve values of all drugs showed that the incidence of adverse reaction of pergolide was relatively high (nausea, 83.5 percent; hallucination, 79.8 percent); the incidence of dyskinesia and somnolence was higher with ropinirole (80.5 and 69.4 percent); in terms of dizziness, the incidence of adverse reaction of piribedil was higher (67.0 percent), and in terms of constipation, the incidence of bromocriptine was relatively high (62.3 percent). "In addition to current forms of treatment, we hope that our results can produce useful information for further development of new drugs to treat Parkinson's disease based on the natures of each drug," the authors write.
