Despite the fact that the incidence of community-acquired pneumonia (CAP) among young people is significantly lower than among older patients, the frequency of hospitalizations for severe CAP among people under 45 years of age remains high. The effectiveness and duration of treatment directly depend on the rationally selected initial empirical antibacterial therapy (ABT).The aim of the study is to analyze the factors influencing the effectiveness of initial empiric antibacterial therapy for CAP in young people in multidisciplinary medical institutions.Materials and methods. The study was designed as a retrospective observational study; it analyzes 105 medical records of young patients with CAP admitted to one of the multidisciplinary hospitals in Moscow from 2017 to 2019.Results. The empiric ceftriaxone + azithromycin ABT regimen (70% of all prescriptions) was ineffective in 13.7% of cases; monotherapy with ceftriaxone (13% of all prescriptions) was ineffective in 57% cases. Severe CAP, acute respiratory failure, systemic inflammatory response syndrome, and exudative pleurisy were diagnosed with significantly higher frequency in the group of patients with ineffective initial empirical ABT. There was no predominance of any comorbid pathology and Charlson Comorbidity Index in groups where the initial ABT was changed and in groups without a change in initial ABT. The microbiological spectrum of CAP pathogens did not significantly differ in young patients between groups with a changed initial empirical ABT and a group without changing initial ABT.Conclusion. The reasons for the ineffectiveness of the initial empirical ABT could be such factors as: underestimation of the risk of the presence of multidrug-resistant pathogens; underestimation of the risk of viral genesis of CAP; underestimation of the severity of CAP, as well as the severity of CAP complications.
尽管年轻人中社区获得性肺炎(CAP)的发病率明显低于老年患者,但45岁以下人群因严重CAP住院的频率仍然很高。治疗的有效性和持续时间直接取决于合理选择初始经验性抗菌治疗(ABT)。本研究的目的是分析影响多学科医疗机构青年CAP初始经验性抗菌治疗效果的因素。材料和方法。本研究设计为回顾性观察性研究;该研究分析了莫斯科一家多学科医院2017年至2019年收治的105例年轻CAP患者的医疗记录。经验头孢曲松+阿奇霉素ABT方案(占所有处方的70%)在13.7%的病例中无效;头孢曲松单药治疗(占所有处方的13%)在57%的病例中无效。严重CAP,急性呼吸衰竭,全身炎症反应综合征,初始经验ABT改变组和未改变初始ABT组在任何共病病理和Charlson共病指数方面均无优势,初始经验ABT改变组和未改变初始ABT组年轻患者CAP病原菌的微生物谱无显著差异ABT.Conclusion。最初经验性ABT无效的原因可能是以下因素:低估了存在多药耐药病原体的风险;低估CAP病毒发生的风险;低估CAP的严重程度,以及CAP并发症的严重程度。

Creation of synergistic combinations of antifungal and antiseptic agents can be considered as one of the promising strategies for reducing the spread of drug resistance in pathogenic fungi.Aim. The aim of this work was to study the synergistic antifungal activity of amphotericin B (AMB) and antiseptic miramistin (MST) in their combined use to fight against drug-resistant Candida isolates. Material and methods. One AMB-resistant C.albicans strain (MIC 3.1 µg/ml), sensitive to MST, two isolates of C.albicans with different level of resistance to MST and AMB (MIC 1.6–6.3 µg/ml), and one MST-resistant C.lusitaniae isolate susceptible to AMB (MIC 0.4 µg/ml) were studied. Isolates’ susceptibility to AMB and MST alone was determined by broth microdilution method and time–kill assay, respectively. Individual anti-candida activity of test combinations of 0.001% MST with AMB in 10 or 50 µg/ml concentrations was studied using quantitative time–kill assay.Results. A significant decrease in the growth of all the isolates treated with both test combinations of MST and AMB in comparison with individual medication treatment was observed at each time interval studied (15–60 minutes). As part of the combination, MST exhibited significant synergy with AMB in sublethal concentration of 10 µg/ml against all the isolates. Treatment of the fungi with a combination of MST with AMB in 50 µg/ml concentration caused complete inactivation of all the isolates after 30 minutes. Under these conditions, AMB exhibited separate antifungal activity.Conclusion. These findings suggest the possible effective use of miramistin in combination with amphotericin B against multi-drug resistant isolates of the genus Candida.
创建抗真菌剂和防腐剂的协同组合可以被认为是减少病原菌耐药传播的有前途的策略之一。本文旨在研究两性霉素B (AMB)和抗菌米米司汀(MST)联合使用对耐药念珠菌的协同抗真菌活性。材料和方法。对MST敏感的1株AMB耐药白色假丝酵母菌(MIC为3.1µg/ml)、2株对MST和AMB均有不同耐药程度的白色假丝酵母菌(MIC为1.6 ~ 6.3µg/ml)和1株对AMB敏感的MST耐药卢西塔菌(MIC为0.4µg/ml)进行了研究。分别用微量肉汤稀释法和时间杀伤法测定菌株对AMB和MST的敏感性。采用定量时间测定法研究了0.001% MST与AMB在10或50µg/ml浓度下的联合抗念珠菌活性。在研究的每个时间间隔(15-60分钟),与单独用药治疗相比,MST和AMB联合试验处理的所有分离株的生长均显著下降。作为组合的一部分,MST与AMB在10 μ g/ml的亚致死浓度下对所有分离株均表现出显著的协同作用。用50µg/ml浓度的MST和AMB联合处理真菌,30分钟后,所有菌株都完全失活。在此条件下,AMB分别表现出抗真菌活性。这些发现提示miramistin联合两性霉素B对念珠菌属多重耐药菌株可能有效。

Lipoglycopeptide antibiotics are semi-synthetic derivatives of glycopeptides and are characterized by a pronounced bactericidal activity against gram-positive pathogens. The aim of the study was comparative assessment of the sensitivity of gram-positive clinical isolates to lipoglycopeptide antibiotics (telavancin, dalbavancin, oritavancin). The following isolates were included in the work: methicillin-resistant Staphylococcus aureus (MRSA, n=780), methicillin-resistant coagulase-negative Staphylococcus spp. (MRCoNS, n=163), and vancomycin-resistant Enterococcus faecium (VREf, n=93). Serial dilutions were used to assess sensitivity with the addition of 0.002% polysorbate 80 to the medium. Lipoglycopeptides showed more pronounced antibacterial activity against MRSA compared to vancomycin, teicoplanin, and daptomycin, and had a MIC₅₀/MIC₉₀ (µg/ml): for telavancin — 0.06 /0.125, for dalbavancin — 0.016/0.06, and for oritavancin — 0.06/0.125. A trend towards an increase in the MIC of lipoglycopeptides and daptomycin was established in MRSA with the MIC of 2 µg/ml for vancomycin, the proportion of which was 13%. For MRCoNS, MIC₅₀ and MIC₉₀ of lipoglycopeptides did not exceed 0.06 µg/ml and 0.125 µg/ml, respectively. Oritavancin showed strong activity against VREf at MIC range of 0.03 µg/ml to 0.5 µg/ml, and at MIC₉₀ of 0.25 µg/ml. Thus, lipoglycopeptide antibiotics are a plausible alternative to vancomycin and daptomycin; they are characterized by pronounced activity and can be used to treat severe forms of staphylococcal infections.
脂糖肽抗生素是糖肽的半合成衍生物,其特点是对革兰氏阳性病原体具有明显的杀菌活性。本研究的目的是比较评估革兰氏阳性临床分离株对脂糖肽类抗生素(特拉万星、达尔巴万星、奥立万星)的敏感性。包括耐甲氧西林金黄色葡萄球菌(MRSA, n=780)、耐甲氧西林凝固酶阴性葡萄球菌(MRCoNS, n=163)和耐万古霉素屎肠球菌(VREf, n=93)。在培养基中加入0.002%聚山梨酯80,用连续稀释法评估灵敏度。与万古霉素、替柯planin和达托霉素相比,脂糖肽对MRSA的抗菌活性更明显,MIC₅₀/MIC₉₀(µg/ml):对特拉万辛- 0.06/0.125,对达尔巴万辛- 0.016/0.06,对奥利塔万辛- 0.06/0.125。在MRSA中,脂糖肽和达托霉素的MIC呈增加趋势,万古霉素的MIC为2µg/ml,占13%。对于mrcon,脂糖肽的MIC₅0和MIC₉0分别不超过0.06µg/ml和0.125µg/ml。Oritavancin在MIC范围为0.03µg/ml至0.5µg/ml, MIC为0.25µg/ml时显示出较强的抗VREf活性。因此,脂糖肽类抗生素是万古霉素和达托霉素的合理替代品;它们的特点是明显的活性,可用于治疗严重形式的葡萄球菌感染。

Medicinal probiotic Sporobacterin is based on the Bacillus subtilis 534 strain, which has been shown to have antimicrobial activity against many bacteria, both the collection strains and the antibiotic-resistant forms of clinical isolates of pathogenic bacteria and fungi. Considering this strain as an antibiotic producer, a step-by-step mutagenic treatment was carried out in order to obtain a variant that consistently exhibits a certain high-level antibiotic activity. A mutant variant was obtained during the three stages of mutagenic treatment and selection; it effectively suppresses the growth of pathogenic staphylococci, including methicillin-resistant staphylococcus (MRSA).
药用益生菌Sporobacterin是基于枯草芽孢杆菌534菌株,它已被证明对许多细菌具有抗菌活性,包括收集菌株和临床分离的致病菌和真菌的抗生素耐药形式。考虑到这种菌株是一种抗生素生产者,为了获得一种始终表现出某种高水平抗生素活性的变体,我们进行了一步一步的诱变治疗。经过诱变处理和选择三个阶段,获得了一个突变体;它能有效抑制致病性葡萄球菌的生长,包括耐甲氧西林葡萄球菌(MRSA)。

Interferons (IFN) have antiviral activity against many viruses, including the SARS-CoV-2. A combination of IFN-a2b and the antioxidant taurine is widely used in the Russian Federation, and its antiviral activity has not been studied before. The aim of this study was to determine the antiviral activity of interferon drugs, in combination with taurine and without it. The study included cytotoxicity and antiviral activity assays of IFN-a2b preparations, when stored according to the instructions at 2–8°C, and after 1 month storage at temperature 20–26 ° C in a pre-opened state. The combination of IFN alpha-2b with taurine has a higher antiviral activity compared to IFN alpha-2b mono-preparation by more than 25% at a «low» and 85% at a «high» multiplicity of infection. Selectivity index for combinations of IFN-a2b (50,000 IU/dose) + taurine (1 mg/ml) and IFN-a2b (10,000 IU/ml) + taurine (0.8 mg/ml) was more than 600 units, whereas for the IFN-a2b (10,000 IU/ml) it was 200 units. The antiviral activity does not change after one month at room temperature. The combination of interferon with taurine at high concentrations was less toxic than interferon. The results obtained demonstrate practicability of interferon alpha-2b and taurine combination use for treatment and prevention of COVID-19.
干扰素(IFN)对包括SARS-CoV-2在内的许多病毒具有抗病毒活性。IFN-a2b与抗氧化剂牛磺酸的组合在俄罗斯联邦广泛使用,其抗病毒活性之前尚未研究过。这项研究的目的是确定干扰素药物的抗病毒活性,联合牛磺酸和不联合牛磺酸。本研究包括IFN-a2b制剂在2-8°C条件下的细胞毒性和抗病毒活性测定,以及在20-26°C条件下的预打开状态下1个月的细胞毒性和抗病毒活性测定。IFN α -2b与牛磺酸联合使用具有更高的抗病毒活性,在“低”感染多重性下比单独使用IFN α -2b的抗病毒活性高25%,在“高”感染多重性下比单独使用IFN α -2b的抗病毒活性高85%。IFN-a2b (50,000 IU/剂量)+牛磺酸(1mg /ml)和IFN-a2b (10,000 IU/ml) +牛磺酸(0.8 mg/ml)组合的选择性指数均大于600单位,IFN-a2b (10,000 IU/ml)的选择性指数为200单位。在室温下放置一个月后,抗病毒活性没有变化。干扰素与高浓度牛磺酸联合使用毒性较干扰素小。结果表明干扰素-2b与牛磺酸联合应用治疗和预防COVID-19的可行性。
