RESUMO
Objective:To evaluate acute kidney injure ( AKI) induced by vancomycin in elderly patients by the determination of serum C ( Cys-C) , creatinine ( Cr) and urine kidney damage factor 1 ( KIM-1 ) in order to provide theoretical evidence for clinical pharmacists helping clinicians make individualized dosage regimen. Methods:A retrospective collection of 48 elderly patients admitted to ICU in our hospital from July 2016 to May 2017 treated with vancomycin for MRSA blood flow infection was carried out. The basic values of serum Cys-C, Cr and urine KIM-1 were determined before the treatment of vancomycin and 6, 12, 24h and 48h after the drug use. According to the AKI diagnostic criteria, the patients were divided into the AKI experimental group and the control group. The se-rum Cr, Cys-C and urine KIM-1 were compared between the groups after the drug use and the clinical diagnostic values of Cys-C and KIM-1 were assessed by the working characteristic curve ROC of the subjects. Results:Totally 32 cases (66. 67%) of patients were with AKI induced by vancomycin at 48h after the administration. Compared with that of the control group, the serum Cr, Cys-C and u-rine KIM-1 was significantly higher respectively at 48h, 24h and 12h after the drug use in the AKI experimental group, and the differ-ences between the groups were statistically significant(P<0. 05). Using serum Cys-C, Cr and urine KIM-1 as the AKI diagnosis, the number of AKI at 12h after the drug use had statistically significant difference (P<0. 05). The results of ROC curve analysis showed that the area under the KIM-1 curve of urine was 0. 797 with 95% confidence interval of 0. 647-0. 947), and the area under the serum Cys-c curve was 0. 582 with 95% confidence interval of 0. 364-0. 799. Conclusion: Compared with the traditional kidney damage markers Cr, serum Cys-C and urine KIM-1 can earlier predict renal function in elderly patients to provide reliable basis for early evalu-ation of renal function, which is helpful to the timely adjustment of vancomycin dosage regimen by clinicians assisted by clinical phar-macists for elderly patients.
RESUMO
Procalcitonin ( PCT) has closely related to the severity of senile pulmonary infection, and its dynamic detection can be used as the auxiliary diagnosis index for elderly severe pneumonia ( SP) . The effects of serum PCT dynamic detection in the early quick identification, diagnosis, disease course monitoring and prognosis evaluation for elderly SP were reviewed, and the effects and clinical significance of the detection in the optimization of antibiotic therapy were also summarized in the paper. The results showed the impor-tant value of PCT dynamic detection in the diagnosis of elderly SP and anti-infection therapy.
