Abstract
Uspjeh transplantacije krvotvornih matičnih stanica (TKM) procjenjuje se analizom statusa kimerizma odnosno, udjela primateljevih stanica u uzorku bolesnika nakon TKMS. Cilj istraživanja bio je usporediti dvije molekularne metode u praćenju kimerizma: metodu umnažanja kratkih uzastopnih ponavljanja DNA lančanom reakcijom (PCR-STR) i metodu lančane reakcije polimerazom u stvarnom vremenu (qPCR) u svrhu određivanja pouzdanosti, osjetljivosti i preciznosti metoda ovisno o omjeru primateljevih i davateljevih stanica u uzorku bolesnika nakon TKMS. Istraživanje je obuhvatilo 12 parova primatelj-davatelj te sveukupno 42 uzorka kimera u kojima je udio primateljevih stanica bio u rasponu od 10-90%. Od 21 analiziranog lokusa STR, najinformativnijima su se pokazali lokusi D13S797, D18S976 i D21S1442, dok je među 30 biljega qPCR za daljnu analizu su najčešće upotrebljavani biljezi KMR040 i KMR050. Raspon dobivenih vrijednosti za udio primateljevih stanica su u prosjeku bio je manji za lokuse STR nego raspon dobiven analizom biljega qPCR. Istraživanje je pokazalo da je metoda qPCR manje pouzdana od metode PCR-STR u određivanju udjela primateljevih stanica kod bolesnika s >10% udjela vlastitih stanica u uzorku nakon TKMS. Zaključno, metoda PCR-STR je bolji izbor za praćenje kimerizma kod bolesnika s visokim udjelom primateljevih stanica.
Abstract (english)
Success of hematopoietic stem cell transplantation (HSCT) is evaluated by chimerism analysis, which is based on determination of recipient and donor cells ratio in patient's sample after HSCT. Purpose of this study was to compare two molecular methods in chimerism monitoring: Short Tandem Repeat-Polymerase Chain Reaction (STR-PCR) and Real time-Polymerase Chain Reaction (qPCR), in order to determine their reliability, sensitivity and accuracy depending on ratio of recipients and donors cells in recipient’s sample after HSCT. This study included 12 recipient-donor pairs and altogether 42 post-HSCT samples in which recipient’s cell ratio was in the range of 10-90%. Out of 12 analysed STR loci the most informative ones were D13S797, D18S976 and D21S1442, while among 30 investigated qPCR markers, KMR040 and KMR050 were most frequently used for chimerism analysis. Range of values obtained for percentage of recipient cells was lower for STR loci in comparison to the one obtained by analysis of qPCR markers. The study showed that qPCR is less reliable then STR-PCR for chimerism monitoring for patients with >10% of their own cells in post HSCT sample. In conclusion, PCR-STR method is a better choice for chimerism status monitoring of those patients with a higher percentage of recipient cells.
