ABSTRACT
OBJECTIVE@#To explore the correlation between peripheral blood cytomegalovirus (CMV) DNA level and cyclosporine A (CsA) plasma concentration among allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients who received immunosuppressant treatment, and to evaluate the potential clinical value.@*METHODS@#A total of 32 allo-HSCT patients were enrolled and their data were analyzed retrospectively. Ganciclovir was used to prevent CMV infection before the transplantation. Routine fluorescence PCR was admitted to test the blood CMV DNA level. The patients were divided into 2 groups: a CMV DNA positive group and a CMV DNA negative group. Enzyme multiplied immunoassay technique was adopted regularly to monitor the blood CsA concentration. The correlation between CMV DNA level and CsA concentration was analyzed.@*RESULTS@#The CMV infection rate in patients who received allo-HSCT was 53.13%. The blood CsA concentration in the CMV DNA positive group was significantly higher than that in the CMV DNA negative group (P<0.05). Through the ROC curve, the area under the curve on Day 1, 7, and 14 had statistical significance compared with 0.5, and the corresponding blood CsA concentration was 203.15, 215.55, and 302.65 ng/mL, respectively.@*CONCLUSION@#Immunosuppressive drug concentration can affect the dynamic changes of CMV DNA. High blood CsA concentration may be one of the reasons for CMV infection. Monitoring the blood CsA concentration may provide guidance for clinical treatment.

Objective To evaluate the application value of UF-1000i automated urine formed elements analyzer in the diagnosis of urinary tract infection. Methods 150 urine specimens were analyzed using the UF-1000i in parallel with detection of leukocyte, yeast-like fungus, and bacteria. These detection results were collected for evaluation of urinary tract infection and scatter grams were recorded. At the same time, these samples were cultured for bacterial identification, which results were compared with that of the UF-1000i. The clinical diagnose criteria of the UTI was performed as golden standard. As compare with results obtained with UF-1000i, the sensitivity and specificity of UF-1000i for diagnosis of urinary tract infection were evaluated, and the consistency were analyzed among scatter grams, bacterial culture and final diagnosis. Results The statistical results from 146 specimens showed that the positive rate of UF-1000i was 32. 9% (48/146), the positive rate of urine culture is 28. 8% (42/146). There was no significant statistical difference found (χ2 = 1.79 ,P = 0. 18 )and Kappa test showed a considerable consistency (K = 0. 775 6). The UF-1000i detection results showed the sensitivity 76. 0% ( 38/50 ), specificity 89. 6% ( 86/96 ), positive predictive value 79. 2% ( 38/48 ) and negative predictive value 87. 8% ( 86/98 ), respectively. The distribution of coccus and bacilli obtained from the UF-1000i testing was basically in accordance with the results of bacterial culture. Conclusion The "UTI-information" of UF-1000i is very important for the diagnosis of urinary tract infections.
