ABSTRACT

In order to provide inspirations and suggestions for the development of medical examination methods in the future, this essay applies SWOT analysis to probe into the strengths (S), weaknesses (W), opportunities (O) and threats (T) of current online assessment method, matches any two of them for analysis, and therefore puts forward four strategies accordingly from the perspective of SO, WO, ST and WT.

ABSTRACT

Objective:Objective To explore the clinical values of next-generation sequencing (NGS) in bacterial 16S rRNA region and fungal ITS region for diagnosing and treating urinary tract infection (UTI) in renal transplant recipients.Methods:A total of 90 mid-stream clean-catch urine samples were collected from renal transplant recipients who were diagnosed with UTI at Hospital from January 2017 to December 2019. Each sample was equally divided and tested via NGS method and traditional urine culture separately. The results of pathogen test and detection rate were analyzed and compared.Results:And 21/90 sample were considered to be contaminated due to the identification of three or more kinds of microorganisms by culture. And among the remaining 69 samples, 36 (52.17%) cases tested positive by 16S rRNA sequencing, 25 (36.23%) positive by urine bacterial culture; meanwhile, 34(49.28%) tested positive by ITS sequencing and 4(5.80%) positive by urine fungal culture.Conclusions:The detection rate of both bacteria and fungi in NGS microorganism testing is higher than that in traditional urine culture ( P< 0.05). For renal transplant recipients with UTI, NGS microorganism testing is an effective supplement for traditional urine culture. Improving the detection rate and accuracy of etiology may enable an optimization of individualized treatment.

ABSTRACT

OBJECTIVE@#To analyze the characteristics of BK polymavirus (BKV) infection and the optimal time window for intervention in kidney transplant recipients (KTRs).@*METHODS@#We retrospectively analyzed the clinical data and treatment regimens in 226 KTRs in our center between January, 2013 and January, 2018. Among the recipients, 157 had a urine BKV load ≥1.0×10 copy/mL after transplantation, and 69 had a urine BKV load below 1.0×10 copy/mL (control group).@*RESULTS@#Among the 157 KTRs, 60 (38.2%) recipients were positive for urine BKV, 66 (42.0%) had BKV viruria, and 31(19.7%) had BKV viremia. The incidence of positive urine occult blood was significantly higher in BKV-positive recipients than in the control group ( < 0.05). The change of urine BKV load was linearly related to that of Tacrolimus trough blood level (=0.351, < 0.05). In urine BKV positive group, the average estimated glomerular filtration rate (eGFR) was below the baseline level (60 mL·min·1.73 m) upon diagnosis of BKV infection reactivation, and recovered the normal level after intervention. In patients with BKV viruria and viremia, the average eGFR failed to return to the baseline level in spite of improvement of the renal function after intervention.@*CONCLUSIONS@#Positive urine occult blood after transplantation may be associated with BKV infection reactivation in some of the KTRs. BKV infection is sensitive to changes of plasma concentration of immunosuppressive agents. Early intervention of BKV replication in KTRs with appropriate dose reduction for immunosuppression can help to control virus replication and stabilize the allograft function.
