ABSTRACT
Objective To understand the distribution and drug resistance of pathogenic bacteria in sputum culture of pneumonia, and to provide evidence for the rational application of clinical antibacterial drugs . Methods The clinical data of 475 patients with positive sputum bacterial culture admitted to department of respiratory medicine of Neijiang Hospital of Traditional Chinese Medicine from May 2020 to May 2023 were collected. The types and drug resistance of pathogenic bacteria isolated from sputum culture were statistically analyzed . Results A total of 539 strains of pathogenic bacteria were isolated from the sputum culture of 475 patients with pneumonia, including 344 strains (63.82%) of Gram-negative bacteria [mainly Klebsiella pneumoniae (79 strains, 14.66%)] and 195 strains (36.18%) of Gram-positive bacteria [mainly Streptococcus pneumoniae (70 strains, 12.99%)]. Klebsiella pneumoniae was highly sensitive to aztreonam, levofloxacin, amikacin, imipenem, and ertapenem, with the sensitivity rates of 94.67%, 92.41%, 94.87%, 96.00% and 98.67% respectively. Streptococcus pneumoniae was absolutely sensitive to teicoplanin, vancomycin and linezolid, and was highly sensitive to cefpirome, levofloxacin, imipenem and ertapenem, with the sensitivity rates of 94.29%, 91.43%, 97.14% and 98.48%. Conclusions The common pathogenic bacteria of patients with pneumonia in Neijiang Hospital of Traditional Chinese Medicine include Klebsiella pneumoniae and Streptococcus pneumoniae. Various pathogenic bacteria have different degrees of resistance to common antibacterial drugs. It is necessary to combine with the types and drug susceptibility results of pathogenic bacteria for the rational application of antibacterial drugs.
ABSTRACT
Objective:To compare the efficacy of different antibacterial drugs combined in the treatment of adult brucellosis patients.Methods:Using a prospective design, 60 adult brucellosis patients admitted to the Affiliated Hospital of Jining Medical University from January 2018 to December 2021 were selected as the study subjects. They were randomly divided into an observation group ( n = 30) and a control group ( n = 30) using a random number table method. The observation group was treated with rifampicin combined with minocycline, and the control group was given rifampicin combined with doxycycline. The course of treatment in both groups was 6 weeks. The efficacy and clinical symptom disappearance time between the two groups, as well as the blood white blood cell count (WBC), alanine aminotransferase (ALT) levels, and serum interferon-γ (IFN-γ), interleukin-4 (IL-4) and interleukin-10 (IL-10) levels before and after treatment, and the occurrence of adverse reactions were compared. Results:The total effective rate of the observation group (96.67%, 29/30) was higher than that of the control group (73.33%, 22/30), with a statistically significant difference (χ 2 = 4.71, P = 0.030). The disappearance time of joint pain, hyperhidrosis, gastrointestinal reactions, and fever in the observation group were shorter than those in the control group, and the differences were statistically significant ( P < 0.05). After treatment, the blood WBC and ALT levels in both groups decreased compared to before treatment ( P < 0.05). After treatment, the blood WBC and ALT levels in the observation group were lower than those in the control group ( P < 0.001). The levels of serum IFN-γ and IL-10 were both decreased after treatment compared to before treatment in two groups, while IL-4 level increased compared to before treatment ( P < 0.05). The levels of serum IFN-γ and IL-10 in the observation group were lower than those of the control group, while IL-4 level was higher than that of the control group ( P < 0.001). The incidence of adverse reactions in the observation group (13.33%, 4/30) was lower than that in the control group (36.67%, 11/30), and the difference was statistically significant (χ 2 = 4.36, P = 0.037). Conclusion:The combination of rifampicin and minocycline in the treatment of adult brucellosis patients has good efficacy and can reduce serum IFN-γ and IL-10 levels and increase IL-4 level with few adverse reactions.
ABSTRACT
The incidence of augmented renal clearance (ARC) in intensive care patients (ICU) is exceptionally high, and these patients are often co-morbid with infection. The occurrence of ARC will significantly increase the clearance rate of antibiotics, making it difficult for conventional doses to reach effective therapeutic concentrations and affect the patient's anti-infective treatment effect and prognosis. It can be seen that it is crucial to formulate a reasonable dosing regimen for ICU patients with ARC. Regrettably, few reports in China about the adjustment strategy of antibiotic dosing regimens for ARC patients. Therefore, this article reviews the domestic and foreign literature for reference to provide evidence for medical personnel to adjust the dose of antibacterial drugs for such patients.
ABSTRACT
Objective:To evaluate the effectiveness of the information management system on the clinical application of special-grade antimicrobial.Methods:Using the established knowledge database, a computer program was designed and developed, which was embedded in the electronic medical record to intervene the clinical use of the special-grade antimicrobial since 2015. The basic information of all discharged patients from the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2013 to December 2020 were extracted from the HIS system, including the medical orders for antibiotics and the drug storehouse dispensing data.The trend analysis was carried out on the changes of the use rates and antibiotic use density (AUD) of the special-grade antimicrobials in the whole hospital and intensive care units (ICU). The data were processed and analyzed using SPSS 24.0.Results:From 2013 to 2015, except for meropenem and amphotericin B, the usage rate of all special-grade antimicrobials in the whole hospital showed an upward trend ( P<0.05). The proportion of special-grade antimicrobials used in the hospital increased year by year ( χ2=7 804.081, P<0.01). The total usage rate of special-grade antimicrobials in ICU showed an upward trend year by year ( χ2=67.028, P<0.01). Since the implementation of the special-grade antimicrobial information management system in 2015, the total use rate of special-grade antimicrobials in the hospital, the use rate of various antibiotics except linezolid, amphotericin B and posaconazole, and the proportion of special-grade antimicrobials used in the hospital have all shown a downward trend year by year ( P<0.01). The total usage rate and total AUD of special-grade antimicrobials in ICU showed a decreasing trend year by year ( χ2=343.514, P<0.01, β=-0.963, P=0.002). Conclusion:The information management system for special-grade antimicrobial can effectively reduce the utilization rate and AUD of most special-grade antibiotics in hospitalized patients including ICU, and has a good clinical application value in antimicrobial stewardship.
ABSTRACT
This article reviews the status quo of new antimicrobial agents that have been approved or undergoing phase Ⅱ/Ⅲ clinical trials in last five years at home and abroad, including new β-lactamase inhibitors and their compound preparations, oxazolidinones, tetracyclines, aminoglycosides, glycopeptides, quinolones, new antifungal agents, cyclic lipopeptides and new anti-mycobacterial agents. The antibacterial activities, main mechanisms of drug resistance, and progress of clinical studies of 27 new drugs were introduced to provide a reference for their clinical application.
ABSTRACT
OBJECTIVE：To provi de reference for classification ，selection and management of antibacterial drugs in medical institutions. METHODS ：The adjustment of antibacterial drug list in 2019 edition of National Basic Medical Insurance ，Work Injury Insurance and Maternity Insurance （called“New List ”for short ）was introduced. The politic reference of selection and adjustment of antibacterial drugs and the principle of classification selection in medical institutions were sort out. The challenges which may bring to pharmaceutical administration and clinical use in medical institutions were investigated. RESULTS & CONCLUSIONS： Three new varieties of the antibacterial drugs in the New List have been added ，including Doxycycline injection，Faropenem granules and Metronidazole oral regular-release preparations. Nine product specifications were excluded ，such as Tetracycline oral regular-release preparations ，Dirithromycin oral regular-release preparations ，etc. The limitation of indications and/or indications of 19 regulations was modified ，and some antibacterial requirements were limited to patients with clear evidence of drug sensitivity test or severe infection. When classifying and selecting antibacterial drugs ，medical institutions should take the existing policy documents as the basis ，strictly implement the relevant provisions of antibacterial drug management ，give priority to meeting various national prescription sets and drug list varieties ，select drugs with sufficient evidence-based treatment basis ，drug quality and safety ，and take into account the convenience and economy of drug use ，supply guarantee service capacity of drug production and circulation enterprises and local situation of pathogenic bacteria resistance. The adjustment of New List also brings challenges to use and management of antibacterial drugs in medical institutions. For example ，New List emphasizes“limited drug sensitivity evidence ”for many antibacterial specifications. But if the clinicians choose drugs mechanically according to the drug sensitivity results and ignores the experience treatment in anti-infection treatment ，another type of “abuse”may be abused ；in addition，the indications of myxomycetin B and colistin （sulfate myxomycetin ）are completely different ，which also deserves further study.
