The same results suggest that although there was no statistical difference between two methods, even rare human errors in manual analysis can reduce the recipients’ chance of transplantation or expose them to an unforeseen risk. As previously shown, the EpHLA software was capable of automatically executing the HLAMatchmaker algorithm as accurately as the conventional

manual method on an LDK378 ic50 Excel spreadsheet. Therefore, the EpHLA software fulfilled the functionality requirements because it accomplished the task to which it was designed with no errors in applying the algorithm. During a period of 3 months, the EpHLA software was continuously used by 11 different users to perform analysis of 110 single antigen results. During this validation period there were no errors due to EpHLA software failures. Therefore, the automation tool enabled the performance of reliable HER2 inhibitor histocompatibility analyses. The emerging results of this study make it evident that users with minimal knowledge of the fundamentals about HLAMatchmaker are able to easily operate the EpHLA software. It is noteworthy that the automation of manual steps enabled the user to have a higher productivity in analyzing single antigen results. The decrease in the average time for this analysis was evidenced when users improved their skills with the EpHLA software (Table 3). The EpHLA program does not need a computer with any special configuration in order to

run. An adequate efficiency can be obtained when running on low-performance machines. During its validation, the EpHLA software was used in Core 2 Duo machines with 2 GB of RAM. In these machines the response for each input applied to the EpHLA software was as fast as observed with the HLAMatchmaker algorithm run on an Excel spreadsheet (a few milliseconds). Thus, the Galeterone EpHLA software may perform all necessary operations on standard computers. In spite of the ability of the HLAMatchmaker algorithm to improve the allocation

of solid organs for highly sensitized patients [15], the widespread use of this tool is limited by the manually demanding and time consuming intermediate steps. To solve this problem, we have developed a new software called EpHLA, which fully automates the functional steps of the HLAMatchmaker algorithm [16]. The present study has shown that the EpHLA software facilitates the identification of AMMs in a considerably shorter time while maintaining the same level of accuracy when using the conventional HLAMatchmaker algorithm. Since the EpHLA program is saving time and it is easy to use, we predict that it will have a significant impact on the applicability of epitope-based histocompatibility matches of donors for sensitized recipients. The EpHLA program is also very useful to interpret antibody-mediated rejections by identifying immunogenic epitopes. For these reasons, the speed of generating results and their accuracy have gained great importance [19].
