RESUMO
OBJECTIVE To observe the efficacy and safety of ceftazidime and avibactam sodium （CAZ/AVI） in the treatment of carbapenem-resistant organism （CRO） infection. METHODS The information of patients with CRO infection admitted to the Second Affiliated Hospital of Soochow University from September 2019 to March 2022 was collected， and the patients were retrospectively divided into observation group （48 cases） and control group （48 cases） according to the treatment plan. The control group was given Polycolistin B sulfate for injection intravenously at a dose of 500 000 U every 12 hours； no dose adjustment was performed in patients with renal insufficiency or receiving continuous renal replacement therapy （CRRT）. The observation group was given continuous micropump of CAZ/AVI for injection intravenously at a dose of 2.5 g every 8 hours for 2 continous hours； among them， the patients with renal insufficiency received an adjusted dose based on creatinine clearance， and no dose adjustment was performed in patients receiving CRRT. The clinical efficacy and microbiological efficacy as well as body temperature， white blood cell （WBC）， C-reactive protein （CRP） and procalcitonin （PCT） before and after treatment were compared between 2 groups. The prognosis and the occurrence of adverse drug reactions were recorded. The factors influencing the clinical efficacy were screened by Logistic regression analysis. RESULTS The effective rate and microbial clearance rate of the observation group were significantly higher than the control group （P＜0.05）. After treatment， body temperature， PCT and CRP of 2 groups were significantly lower than before treatment， and CRP of the observation group was significantly lower than the control （No.SDFEYJLC2105） group （P＜0.05）. There was no statistically significant differencebetween the two groups in terms of rehabilitation discharge rate， the proportion of patients transferred to general wards，the proportion of dead patients， and the total incidence ofadverse drug reactions （P＞0.05）. CAZ/AVI and prolonging therapy duration were more likely to achieve clinical benefits （odds ratios of 1.146， 7.707，P＜0.05）， while lung infection and CRRT may be independent risk factors for treatment failure （odds ratios of 0.182， 0.236， P＜0.05）. CONCLUSIONS CAZ/AVI has good efficacy and safety in the treatment of CRO infection， the appropriate extension of antibacterial treatment time can achieve a higher clinical response rate， while lung infection or CRRT may lead to treatment failure.
RESUMO
Objective:To preliminarily discuss the difference of ovary anti-miillerian hormone ( AMH) when cyclophosphamide is used in different time during menstrual cycle .Methods:Totally 30 young female patients with average age of (36 ±6.39) diagnosed as glomerular disease were treated with cyclophosphamide .According to the medication time , the patients were divided into follicular phase group and secretory phase group based on the property of menstrual cycle .Follicular phase group was treated with cyclophospha-mide during the first day and the eighth day of menstrual cycle .Secretory phase group was treated with cyclophosphamide after ovulato-ry time, namely the 14th day-the 16th day of menstrual cycle.AMH was detected before the drug treatment and 1st, 3rd, 6th and 10th cycles after cyclophosphamide treatment in the two groups .Results: AMH in the five periods had no statistic difference between the groups (P>0.05).There was significant difference in AMH before the treatment and after one-month treatment in the same group(P<0.05).AMH in different age groups showed statistic difference (P<0.05).Conclusion:There is no significant difference in AMH when cyclophosphamide is administrated in different time of menstrual cycle .However , ovarian function is impaired just by low dose cyclophosphamide (0.8g) with the first administration and will be recovered slowly at least half a year after the drug withdrawal .
RESUMO
Objective@#To evaluate the effects of application of vancomycin in the early stage of patients with extremely severe burn, in order to provide reference to drug for anti-infection treatment in the early stage of patients with extremely severe burn.@*Methods@#Data of 15 patients of Kunshan explosion on August 2nd, 2014, admitted to the Department of Intensive Care in our hospital were retrospectively analyzed. The clinical efficacy of continuously intravenous dripping of vancomycin (combined with imipenem) in the early stage of burns (before and on post burn day 14) was analyzed. (1) The steady state plasma concentration of vancomycin was monitored respectively 30 min before the third, sixth, and tenth medication with direct chemiluminescent imaging method. (2) The distribution of Gram-positive bacteria of patients during hospitalization and their drug resistance to 14 antibiotics commonly used in clinic were analyzed. (3) Serum level of procalcitonin (PCT), white blood cell count, percentage of neutrophils before and after treatment, and efficacy grade of anti-infection treatment in the early stage of burns were analyzed. (4) Serum levels of aspartate transaminase (AST), alanine aminotransferase (ALT), creatinine before and after treatment, and the adverse effects during medication were analyzed. The WHONET 5.5 statistical software was used to analyze the distribution of Gram-positive bacteria in all the pathogens, and the status of drug resistance of Gram-positive bacteria to 14 antibiotics. Data were processed with Wilcoxon rank sum test.@*Results@#(1) Twenty-nine times of steady state plasma concentration monitoring were performed in the patients in total, with the steady state plasma concentration of vancomycin from 4.3 to 42.1 μg/mL. In the monitoring before third, sixth, and tenth medication, the percentages of result reaching the standard were respectively 1, 3/14, and 2/7. (2) A total of 79 Gram-positive bacteria were isolated, including 49 (62.03%) strains of Staphylococcus aureus, 9 (11.39%) strains of Staphylococcus haemolyticus, 7 (8.86%) strains of Staphylococcus epidermidis, 12 (15.19%) strains of Enterococcus faecium, and 2 (2.53%) strains of Enterococcus faecalis. The above-mentioned Staphylococcus strains were with high drug resistance to antibiotics including penicillins, erythromycin, ciprofloxacin, and low drug resistance to linezolid, teicoplanin, and nitrofurantoin. The above-mentioned Enterococcus strains were with high drug resistance to antibiotics including erythromycin, ciprofloxacin, gentamicin, and low drug resistance to linezolid and teicoplanin. The above-mentioned Staphylococcus strains were all sensitive to vancomycin. Two strains of vancomycin-resistant Enterococcus were detected in the above-mentioned Enterococcus strains. (3) Serum level of PCT, white blood cell count, percentage of neutrophils of patients were (8.1±7.5) ng/mL, (24±10)×109/L, and 0.898±0.029 before treatment, which were significantly higher than (3.0±2.8) ng/mL, (12±5)×109/L, and 0.867±0.016 after treatment (with Z values respectively -2.103, -3.237, and -3.068, P<0.05 or P<0.01). After the early treatment, excellence, progess, and invalid results were achieved in 7, 5, and 3 patients, with the effective percentage of 4/5 in clinic. (4) There were no statistically significant differences in serum levels of AST, ALT, and creatinine of patients between before and after treatment (with Z values respectively-0.057, -1.508, and -1.363, P values above 0.05). Only one patient had liver and renal dysfunction during treatment.@*Conclusions@#The positive and reasonable use of vancomycin can remove most of the Gram-positive bacteria, and control the development of sepsis combined with imipenem in the early stage of patients with extremely severe burn. However, the dose of vancomycin should be individualized and the steady state plasma concentration should be monitored to maintain the blood concentration within the safe and effective range, so as to improve the rational use of vancomycin.
RESUMO
OBJECTIVE:To analyze the blood concentration monitoring data of 4 commonly used antiepileptic drugs(AEDs, sodium phenytoin,carbamazepine,sodium valproic acid,oxcarbazepine)in order to provide reference for rational use of drugs in the clinic. METHODS:415 patients underwent 4 AEDs blood concentration monitoring were selected from our hospital during 2014-2015,and the results of blood concentration monitoring were analyzed statistically. RESULTS:There were 680 cases of AE-Ds blood concentration monitoring in total. The main objects of serum concentration monitoring were young and middle-aged(range from 19 to 60),involving 449 cases in total(66.03%). 360 cases were in the normal range(52.94%). Among 361 patients receiving single drug therapy,the rates of serum concentration in the normal range were 80.77%for carbamazepine,which was higher than oth-er 3 AEDs(30.00% for sodium phenytoin,47.40% for sodium valproic acid and 40.38% for oxcarbazepine),with statistical signifi-cance(P<0.05). Among 54 patients receiving combination therapy,the serum concentration monitoring data of 67.65%patients treat-ed with double-combination therapy and 100%patients treated with triple-combination therapy deviated from normal range. CONCLU-SIONS:The rate of AEDs blood concentration reaching the normal range are in low level in our hospital. It’s necessary to strengthen medication education for patients to improve the compliance of patients;clinical efficacy of AEDs is evaluated on the basis of blood concentration monitoring and clinical symptom,and combination therapy should be avoided as much as possible.
RESUMO
Objective The value of using partial spleen embolization (PSE) in the treatment of hyper-splenism. Methods Using mixed antibiotic 60% meglucamine diatrizoate, we injected tiny gelatinsponges as embolus to 34 cases of hypersplenism for making spleen artery embolization between 1989 and 2001. Results In the 34 cases of hypersplenism who used PSE, the 26 cases had gained CR(76.5%)and the 6 cases had gained PR(17.6%). The overall effective rate was 94.1%. Tracing the 26 cases who had gained CR, there were 7 cases relapsed. And the recurrence rate was 26.9%. Conclusion The using areas of PSE are wide. And the curative effect is exact. PSE can completely replace the operation of splenectomy with mastering skill and attending complication.
RESUMO
Objective To study the clinical value of 3 methods of bronchial artery embolization for the treatment of massive hemoptysis, and to observe healing effect and complication after different methods and embolic materials. Methods Selective bronchial artery embolization was performed in 93 patients with massive hemoptysis, among them 26 were embolized with simple gelfoam particles, 30 patients with sandwich bronchial artery embolization, and 37 patients with fourfold sandwich bronchial artery embolization. All patients were followed up for six to twenty-four months. Results The recent efficiency rates of three groups were as follows: simple gelfoam particles 92%(24/36), sandwich bronchial artery embolization 100%(30/30), fourfold sandwich bronchial artery embolization 100%(37/37). There was recrudescence in patients with treatment of simple gelfoam particles and sandwich bronchial artery embolization, but no recrudescence was found in patients treated with fourfold sandwich bronchial artery embolization. Conclusion Fourfold sandwich bronchial artery emblization is one of simple and highly effective methods with minimal trauma in treating massive hemoptysis.
