Popis: Surgical procedure has immense impact on the immune balance. However, little is known about perioperative changes in T regulatory and Th17 lymphocyte subpopulations in patients undergoing colorectal resection. Patients with resectable colon cancer were enrolled in the study. Blood samples were obtained on two occasions, i.e. before the procedure and two days after the surgery. We also recruited a control group of young, healthy individuals. Lymphocyte subpopulations were analyzed with the use of flow cytometry. Investigated subpopulations consisted of total lymphocyte count, CD4+, CD8+, T regulatory Foxp3+ (Tregs), Th17 lymphocytes and white blood cell (WBC) count. There were significant differences in immune cell levels before and after the surgery. Reduction was recorded in the CD4+, CD8+, Tregs and total lymphocyte counts (p=0.002, p=0.01, p=0.008 and p=0.001, respectively). Increase was observed in total WBC and Th17 cells, however, Th17 lymphocytes did not reach statistical significance (p=0.01 and p=0.5, respectively). In conclusion, surgical intervention caused changes in all lymphocyte subpopulations investigated in patients undergoing surgery for colorectal cancer. However, it seemed to be an effect of perioperative trauma. Further studies are needed to investigate the impact of surgical intervention on lymphocyte subpopulations.
Kirurški zahvat ima golem učinak na ravnotežu imunog sustava. Međutim, malo se zna o perioperacijskim promjenama u subpopulacijama T regulatornih i Th17 limfocita u bolesnika podvrgnutih resekciji kolorektuma. U istraživanje su bili uključeni bolesnici s resektabilnim karcinomom kolona. Uzorci krvi prikupljeni su dva puta: prije zahvata i dva dana nakon operacije. Uključena je bila i kontrolna skupina sastavljena od mladih i zdravih osoba. Subpopulacije limfocita analizirane su protočnom citometrijom. Istraživane su sljedeće subpopulacije: ukupan broj limfocita, CD4+, CD8+, T regulatorni Foxp3+ (Tregs), Th17 i bijela krvna slika. Utvrđene su značajne razlike u razinama imuno stanica prije i nakon operacije. Snižene razine zabilježene su za CD4+, CD8+, Tregs i ukupni broj limfocita (p=0,002, p=0,01, p=0,008 odnosno p=0,001). Povišenje je zapaženo za bijelu krvnu sliku i Th17 stanice, međutim, Th17 limfociti nisu postigli statističku značajnost (p=0,01 odnosno p=0,5). Zaključujemo da je kirurški zahvat uzrokovao promjene u svim istraživanim subpopulacijama limfocita kod bolesnika podvrgnutih operaciji kolorektalnog karcinoma. Međutim, čini se da je to bio učinak perioperacijske traume. Potrebna su daljnja istraživanja kako bi se ispitao utjecaj kirurškog zahvata na subpopulacije limfocita.
