肝移植术后血清降钙素原监测的临床意义

Objective To investigate the changes of procalcitonin (PCT) in patients after liver transplantation and explore their significance for diagnosis and differential diagnosis among bacterial infection, viral infection and acute rejection.Methods PCT was measured in serum of 25 liver trans-plant patients by immunofluorescence sandwich method and the patients were divided into the non-complication group, viral infection group, acute rejection group and bacterial infection group.Results The concentrations of PCT in the 1st, 2nd and 3rd day after transplantation were(24.50 ± 4.6)ng/ml, (21.40± 3.3)ng/ml and (12.25 ± 3.1)ng/ml, respectively and they presented a decreasing tendency.The concentrations of PCT in non-complication group, viral infection group and acute rejection group decreased gradually and were near the normal level of (0.51±0.11) ng/ml after 7～10 days.Moreo-ver, the concentrations of PCT in viral infection group and acute rejection group were (0.44 ± 0.16)ng/ml and(0.53±0.14)ng/ml when the patients were in fever.The concentration of PCT in the viral infection group were(15.70±5.1)ng/ml, which was significantly higher than that in other 3 groups (P<0.05) in the early days of fever.The statistical differences among the other three groups were not significant (P>0.05).Conclusion The concentration of PCT in serum is high in the 1st, 2nd and 3rd day then decreased gradually soon.The concentration of PCT is not high in viral infection or acute rejection while significantly high in bacterial infection, so it can be used to differentiate the bacterial infection from acute rejection and virus infection after liver transplantation.

肾移植患者血清中可溶性B7-H3水平的变化及其临床意义

Objective To detect the serum soluble B7-H3 (sB7-H3) in patients before and after renal transplantation, and to investigate the clinical significance. Methods The serum level of sB7-H3 in 34 patients were determined before and 3, 6, 12 months after renal transplantation. Besides, 11 health adults were elected as controls. These 34 patients were divided into two groups according to HLA and/or MICA antibodies using Luminex before operation. After transplantation, all the patients were divided into two groups according to their conditions; group Ⅰ with rejection; group S with stable renal function and no rejection. Results The serum level of sB7-H3 in all 34 patients before operation was significantly higher than health controls [(27. 10 ± 13. 61) μg/L,n = 34 vs (11.61 ±3.77) μg/L,n = 11 ,P ＜0. 01], and significantly higher in patients with antibodies than in those without before operation [(34. 96 ± 17. 37) (μ/L, n = 11 vs (23. 34 ± 9. 75) (μg/L, n = 23, P ＜ 0. 05]. There was no significant difference in the serum level of sB7-H3 between control group and S group after operation (P ＞0. 05). In group Ⅰ, the serum level of sB7-H3 was increased obviously when rejection occurred [(20. 63 ±4. 28) μg/L,n = 12; (18. 95 ±2.98) μg/L,n=6; (28.36 ±19. 83) μg/L,n = 10] , as compared with group S and control group (P＜0. 01), while at the time without rejection, there was no difference among them (P ＞0. 05). Conclusion Monitoring serum sB7-H3 after renal transplantation would be clinically useful in indicating therapeutic effect and outcome of the patients.
