Background: The expected ageing of the population and the increase in the number of patients with osteoporosis require a correct approach to identification of individuals with a high fracture risk, to their rational routing for the work-up and timely prescription of therapy. A preliminary analysis of characteristics of patients referred to specialized osteoporosis centers may help to optimize medical care for these patients. Aim: To analyze the profile of patients referred for densitometry and/or to an osteoporosis specialist at the Moscow Regional Osteoporosis Centre in order to optimize care for this patient population in the region. Materials and methods: The study was performed in the Moscow Regional Osteoporosis Centre located in Moscow Regional Research and Clinical Institute (MONIKI). We retrospectively analyzed medical files of all consecutive outpatients attending the center at their own or with a referral for densitometry and/or specialist consultation January 1 to December 31, 2019. Results: The study included 1940 patients aged 42 to 90 years, with 96.5% (n = 1873) being female, with the mean age of 65.4 8.5 years; males accounted for 3.5% (n = 67), their mean age was 65.6 9.0 years. Patients who had not previously been diagnosed with osteoporosis accounted for 63.8% (n = 1238), whereas 36.2% (n = 702) of the patients have been diagnosed earlier. 27.8% (n = 540) of all patients, were remarkable for the history of low-energy fractures. 88.1% of the patients were referred by endocrinologists or rheumatologists. The main purpose of the referral was to perform densitometry and get the prescription of treatment for osteoporosis (61%). The median FRAX-based risk of major fractures in the total group was 8.2 [6.9; 13.0] % (n = 1277), with the risk in women being significantly higher than in men (8.3 [7; 13] % vs. 4.6 [4.2; 7.7] %, respectively, p 0.001). When bone mineral density was assessed with the T-score (n = 1928), the result of +0.1 SD was found in 6.6% (n = 127), whereas 11.6% (n = 224), 44.4% (n = 856), 37.4% (n = 721) were judged as normal values, osteopenia, and osteoporosis, respectively. According to the specialist consultation in the Centre, a clinical diagnosis of osteoporosis was made in 53.2% of the cases (n = 1032), while 0.3% (n = 5) had another bone disease, 19.2% (n = 373) had no bone disease, and 27.3% (n = 530) had some other problems. The proportion the patients with indications for treatment for osteoporosis was 56% (n = 1089); 45% (n = 489) of them were recommended to initiate therapy, 36.7% (n = 400) continued with their previous medication and 18.3% (n = 200) needed a modification of their management. Conclusion: The study results have shown that patients are frequently referred for densitometry without enough grounds and with a low risk of fracture. This makes highly relevant the use of the FRAX algorithm as a screening tool for diagnosis and timely administration of treatment for osteoporosis not only by s
背景:随着人口老龄化的预期和骨质疏松症患者数量的增加,需要正确识别骨折高危人群,合理安排其随访和及时处方治疗。对转诊到专门骨质疏松症中心的患者的特征进行初步分析,可能有助于优化这些患者的医疗护理。目的:分析在莫斯科地区骨质疏松症中心进行密度测量和/或骨质疏松症专家转诊的患者概况,以优化该地区这类患者的护理。材料和方法:本研究在位于莫斯科地区研究和临床研究所(MONIKI)的莫斯科地区骨质疏松症中心进行。我们回顾性分析了2019年1月1日至12月31日期间所有自行或经转诊接受密度测量和/或专家咨询的连续门诊患者的医疗档案。结果:纳入患者1940例,年龄42 ~ 90岁,女性占96.5% (n = 1873),平均年龄65.4 ~ 8.5岁;男性占3.5% (n = 67),平均年龄65.6 9.0岁。未诊断为骨质疏松的患者占63.8% (n = 1238),而较早诊断的患者占36.2% (n = 702)。27.8% (n = 540)的患者有低能性骨折史。88.1%的患者是由内分泌科或风湿科医生转诊的。转诊的主要目的是进行密度测量和获得骨质疏松症治疗处方(61%)。全组主要骨折的中位frax风险为8.2 [6.9];13.0] % (n = 1277),女性的风险显著高于男性(8.3 [7;13 % vs. 4.6 [4.2;7.7%, p < 0.001)。用t评分法评估骨密度时(n = 1928), 6.6% (n = 127)的结果为+0.1 SD, 11.6% (n = 224)、44.4% (n = 856)、37.4% (n = 721)判断为正常值、骨质减少和骨质疏松。根据该中心的专家咨询,53.2%的病例(n = 1032)被临床诊断为骨质疏松症,0.3% (n = 5)患有其他骨病,19.2% (n = 373)没有骨病,27.3% (n = 530)有一些其他问题。有骨质疏松症治疗指征的患者占56% (n = 1089);45% (n = 489)的患者建议重新开始治疗,36.7% (n = 400)的患者继续治疗,18.3% (n = 200)的患者需要改变治疗方法。结论:研究结果表明,患者在没有足够理由的情况下经常被转诊进行密度测量,并且骨折的风险很低。这使得FRAX算法作为骨质疏松症诊断和及时治疗的筛查工具的使用高度相关,不仅是专家,而且是初级保健医生。

Atypical hemolytic uremic syndrome (aHUS) is a severe life-threatening disease associated with uncontrolled activation of alternative complement pathway. Obstetric aHUS, which develops in pregnant women and puerperas, is characterized by a particularly severe course with multiple organ failure, high death risk and end-stage renal disease. The prognosis of patients with obstetric aHUS has changed dramatically after the introduction of eculizumab, a monoclonal antibody to C5 complement component, into clinical practice. With timely initiation of the complement blocking therapy, the patients would not only survive, but also completely restore the function of the affected organs. Naturally, the question arises on the possibility of repeated pregnancies in women with previous obstetric aHUS and on the strategy of pregnancy management. The paper describes a clinical case of successful treatment with eculizumab for obstetric aHUS in the third trimester of the first pregnancy in a young and previously healthy woman, and the management of her second pregnancy. A 23-year old woman at 35-36 weeks of her first pregnancy developed the clinical picture of obstetric thrombotic microangiopathy, which was interpreted as a manifestation of severe preeclampsia and HELLP syndrome. However, after an emergency surgical delivery, the patient's condition continued to deteriorate despite the plasma exchange procedure. After exclusion of the other causes of thrombotic microangiopathy, aHUS was diagnosed and treatment with eculizumab was started, which resulted in complete recovery. No aHUS-associated mutations were identified. The complement inhibitor treatment was discontinued after 12 months. Four years after the first birth, the patient had a second pregnancy after preconception planning. During pregnancy, the patient was closely monitored for a timely identification of potential complications and had prevention of placental complications with acetylsalicylic acid and low molecular weight heparin. No aHUS recurrence and/or other complications were observed, and the patient did not require treatment with eculizumab during pregnancy. Elective caesarean section was performed at 39 week of gestation. A healthy boy was born with a bodyweight of 3370 g, a height of 50 cm, and Apgar score 8-9. In women with obstetric aHUS history, a favorable outcome of repeated pregnancies is possible, in some cases even without any prophylactic use of complement-blocking therapy, provided that with complete remission of aHUS has been achieved, with close monitoring during gestation and prevention of placenta-associated complications.
非典型溶血性尿毒症综合征(aHUS)是一种与替代补体途径激活失控相关的严重危及生命的疾病。产科aHUS发生于孕妇和产妇,其特点是病程特别严重,伴有多器官衰竭、高死亡风险和终末期肾病。eculizumab是一种针对C5补体成分的单克隆抗体,引入临床实践后,产科aHUS患者的预后发生了巨大变化。及时开始补体阻断治疗,不仅可以使患者存活,而且可以使受病器官的功能完全恢复。自然,问题出现在以前有产科aHUS的妇女重复怀孕的可能性和妊娠管理策略。本文描述了一个临床案例成功治疗与eculizumab产科aHUS在第三个月的第一次怀孕在一个年轻的和以前健康的妇女,并管理她的第二次怀孕。一名首次怀孕35-36周的23岁女性出现产科血栓性微血管病的临床表现,这被解释为严重先兆子痫和HELLP综合征的表现。然而,在紧急手术分娩后,患者的病情继续恶化,尽管进行了血浆交换手术。在排除血栓性微血管病变的其他原因后,诊断出aHUS并开始使用eculizumab治疗,最终完全康复。未发现ahus相关突变。补体抑制剂治疗在12个月后停止。第一次分娩后四年,患者在孕前计划后第二次怀孕。妊娠期间密切监测患者,及时发现潜在并发症,并应用乙酰水杨酸和低分子肝素预防胎盘并发症。未观察到aHUS复发和/或其他并发症,患者在妊娠期间不需要eculizumab治疗。妊娠39周行择期剖宫产。一个健康的男孩出生时体重为3370克,身高为50厘米,阿普加评分为8-9。在有产科aHUS病史的妇女中,重复妊娠的有利结果是可能的,在某些情况下,即使没有任何补体阻断治疗的预防性使用,只要aHUS完全缓解,在妊娠期间密切监测和预防胎盘相关并发症。

In the recent years, immune checkpoint inhibitors (ICPI) have been widely used for treatment of many malignant neoplasms. In the Russian Federation, several ICPIs have been approved and actively used, namely anti-CTLA-4 monoclonal antibody (ipilimumab), anti-PD-1 monoclonal antibodies (nivolumab, pembrolizumab, prolgolimab), and anti-PD-L1 monoclonal antibodies (atezolizumab, durvalumab). ICPIs may cause various endocrine immune-mediated adverse events, most commonly thyroid dysfunction and hypophysitis, which are at large associated with anti-tumor therapy with a certain subgroup of these agents. Predictors of endocrine immune-mediated adverse events remain unclear, and their optimal prevention, prediction and treatment have not been yet defined. The review contains the information accumulated in the literature on the mechanisms, biomarkers, specific characteristics of thyroid immune-mediated adverse events and describes the principles of treatment for these thyroid disorders. This information would be useful for practicing oncologists, endocrinologists, internists, family physicians, as well as for any other medical specialties.
近年来,免疫检查点抑制剂(immune checkpoint inhibitors, ICPI)被广泛应用于多种恶性肿瘤的治疗。在俄罗斯联邦,几种icpi已被批准并积极使用,即抗ctla -4单克隆抗体(ipilimumab),抗pd -1单克隆抗体(nivolumab, pembrolizumab, prolgolimab)和抗pd - l1单克隆抗体(atezolizumab, durvalumab)。icpi可引起各种内分泌免疫介导的不良事件,最常见的是甲状腺功能障碍和垂体炎,这在很大程度上与这些药物的某一亚群的抗肿瘤治疗有关。内分泌免疫介导的不良事件的预测因素尚不清楚,其最佳预防、预测和治疗尚未确定。这篇综述包含了关于甲状腺免疫介导不良事件的机制、生物标志物、特异性特征的文献积累信息,并描述了这些甲状腺疾病的治疗原则。这些信息对肿瘤学家、内分泌学家、内科医生、家庭医生以及其他医学专业都很有用。

Background. Subjective food perceptions in various aspects that could impact food choices and diet adherence by the Russian patients with type 2 diabetes mellitus (T2DM) have not been studied. Aim to assess food perceptions in T2DM patients in the reference group of dairy products and their potential influence on the nutritional structure. Aim: To assess food perceptions in T2DM patients in the reference group of dairy products and their potential influence on the nutritional structure. Materials and methods: This cross-sectional study included 300 consecutive out- and in-patients with T2DM (mean age standard deviation, 60,8 10,2 years, duration of diabetes 1 to 35 years). The patients underwent standard clinical and laboratory work-up and filled in the questionnaire on food perceptions of six dairy products (low fat cottage cheese, low fat milk, high fat milk, sour cream, cheese, and sweet cheese curds) in the following five aspects: impact on general health, impact on prevention of cardiovascular diseases, impact on glycemic control, taste and convenience of the use. These perception aspects were compared with the self-reported frequencies of the use of each product, patients demographic and clinical characteristics. Results: The patients considered low fat cottage cheese to be most healthy for their general health, with low fat milk and cheese ranking 2nd (р 0.0001 compared to low fat cottage cheese). Fat milk and sour cream were perceived as unhealthy (р 0.0001 compared to healthy products). Sweet cheese curds were perceived by the patients as the most unhealthy/harmful (р 0.0001 compared with each of the rest products). All other medical aspects of food perceptions (impact on cardiovascular prevention and diabetes control) moderately or strongly correlated between each other and with the perception for general health (Spearman's r from 0.42 to 0.72, all р 0.0001). Taste perceptions of all products, except sour cream, demonstrated moderate correlation with their perception in terms of convenience of the use (Spearman's r from 0.36 to 0.47, all р 0.0001). Male patients perceived low fat milk as more tasty and sour cream as more healthy, than female patients (р = 0.029 and 0.046, respectively). Female patients found sour cream more tasty (р = 0.019), and low fat cottage cheese and cheese as more healthy, than males (р = 0.009 and 0.014, respectively). The frequencies of the product use was associated with medical aspects of their perceptions: patients use to eat/drink low fat milk, low fat cottage cheese and cheese significantly more often, than high fat milk and sweet cheese curds (р 0.0001), whereas sour cream was in an intermediate position as per its frequency of the use. Low fat cottage cheese and cheese ranked first according to the proportion of their consumers (91.3 and 90.7% of the patients, respectively), low fat milk ranked second (82% of the patients), and sour cream third (75%), whereas most patients abstain from the use of fat
背景。俄罗斯2型糖尿病(T2DM)患者在不同方面的主观食物感知可能影响他们的食物选择和饮食依从性,目前还没有相关研究。目的评估参考组T2DM患者对乳制品的食物认知及其对营养结构的潜在影响。目的:评估参考组T2DM患者对乳制品的食物认知及其对营养结构的潜在影响。材料和方法:本横断面研究纳入300例连续住院和门诊T2DM患者(平均年龄标准差为60、8、10、2岁,糖尿病病程1 ~ 35年)。患者接受了标准的临床和实验室检查,并填写了对六种乳制品(低脂松软干酪、低脂牛奶、高脂牛奶、酸奶油、奶酪和甜奶酪凝乳)的食物认知问卷,内容包括对一般健康的影响、对预防心血管疾病的影响、对血糖控制的影响、口感和使用方便程度。将这些感知方面与自我报告的使用每种产品的频率、患者人口统计学和临床特征进行比较。结果:患者认为低脂农家奶酪对他们的整体健康最有益,低脂牛奶和奶酪排名第二(与低脂农家奶酪相比,为0.0001)。脂肪牛奶和酸奶油被认为是不健康的(与健康产品相比,0.0001)。甜奶酪凝乳被患者认为是最不健康/有害的(与其他产品相比为0.0001)。食物感知的所有其他医学方面(对心血管预防和糖尿病控制的影响)彼此之间以及与总体健康感知之间存在中度或强相关性(Spearman's r从0.42到0.72,均为0.0001)。除了酸奶油外,所有产品的味觉感知都与他们在使用方便性方面的感知表现出中度相关性(Spearman's r从0.36到0.47,均为0.0001)。男性患者比女性患者认为低脂牛奶更美味,酸奶油更健康(分别为0.029和0.046)。女性患者认为酸奶油更美味(= 0.019),低脂松软干酪和奶酪比男性更健康(分别= 0.009和0.014)。产品使用的频率与他们对医疗方面的看法有关:患者食用/饮用低脂牛奶、低脂松软干酪和奶酪的频率明显高于高脂牛奶和甜奶酪凝乳(0.0001),而酸奶油的使用频率处于中间位置。低脂白软干酪和奶酪的食用比例排名第一(分别占91.3%和90.7%),低脂牛奶排名第二(占82%),酸奶油排名第三(占75%),而大多数患者不使用脂肪牛奶和甜奶酪凝乳(分别占32%和32.3%)。参考产品的使用频率与它们的味道或使用的便利性的关系要小得多,与它们的成本/价格完全没有关系。结论:T2DM患者在一般健康、心血管系统、血糖控制等方面能够明显区分参照组产品(乳制品)。在大多数情况下,这些态度与他们的味觉感知无关。正是主观食物感知的医学方面对营养结构(实际使用)的影响比它们的味道或使用的便利性更大。这一事实可能成为在合理营养和饮食领域对患者进行教育的有利背景;然而,患者对食物营养成分及其对健康状况的实际影响的了解需要显著提高。方法。本横断面研究纳入了300例连续住院和门诊T2DM患者(平均年龄60,810岁,2岁,糖尿病病程1 - 35年)。患者接受了标准的临床和实验室检查,并填写了对六种乳制品(低脂松软干酪、低脂牛奶、高脂牛奶、酸奶油、奶酪和甜奶酪凝乳)的食物认知问卷,内容包括对一般健康的影响、对预防心血管疾病的影响、对血糖控制的影响、口感和使用方便程度。将这些感知方面与自我报告的使用每种产品的频率、患者人口统计学和临床特征进行比较。组间比较采用学生t检验、Mann-Whitney检验(取决于数据分布等)、卡方检验和方差分析。食物感知和食物使用频率之间的任何联系都是通过斯皮尔曼相关性来评估的。结果。

These perception aspects were compared with the self-reported frequencies of the use of each product, patients demographic and clinical characteristics. \u0000Results: The patients considered low fat cottage cheese to be most healthy for their general health, with low fat milk and cheese ranking 2nd (р 0.0001 compared to low fat cottage cheese). Fat milk and sour cream were perceived as unhealthy (р 0.0001 compared to healthy products). Sweet cheese curds were perceived by the patients as the most unhealthy/harmful (р 0.0001 compared with each of the rest products). All other medical aspects of food perceptions (impact on cardiovascular prevention and diabetes control) moderately or strongly correlated between each other and with the perception for general health (Spearman's r from 0.42 to 0.72, all р 0.0001). Taste perceptions of all products, except sour cream, demonstrated moderate correlation with their perception in terms of convenience of the use (Spearman's r from 0.36 to 0.47, all р 0.0001). Male patients perceived low fat milk as more tasty and sour cream as more healthy, than female patients (р = 0.029 and 0.046, respectively). Female patients found sour cream more tasty (р = 0.019), and low fat cottage cheese and cheese as more healthy, than males (р = 0.009 and 0.014, respectively). The frequencies of the product use was associated with medical aspects of their perceptions: patients use to eat/drink low fat milk, low fat cottage cheese and cheese significantly more often, than high fat milk and sweet cheese curds (р 0.0001), whereas sour cream was in an intermediate position as per its frequency of the use. Low fat cottage cheese and cheese ranked first according to the proportion of their consumers (91.3 and 90.7% of the patients, respectively), low fat milk ranked second (82% of the patients), and sour cream third (75%), whereas most patients abstain from the use of fat","PeriodicalId":7638,"journal":{"name":"Almanac of Clinical Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72653883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Endothelial dysfunction is recognized as one of the early markers of cardiovascular disorders. It is supposed to be a potential predictor of cardiovascular complications in patients receiving adjuvant and neoadjuvant chemotherapy. Aim: To estimate the prevalence of endothelial dysfunction in solid cancer patients compared to that in individuals without any malignancies. Materials and methods: This observational study included 74 patients with solid malignancies, mostly gastrointestinal. Prior to polychemotherapy, all patients were examined for endothelial function of small and large arteries (AngioScan-01, Fiton, Russia) and peripheral artery stiffness (pulse wave contour analysis and occlusion test). The results were compared with those of the Russian population trials of endothelial dysfunction Meridian-RO (Ryazan region) and trial in the rural population of the Krasnodar region. Results: Compromised vasodilation and smaller arteries tone were found in 64.9% (48/74) of the cancer patients, while impaired vasodilation of larger muscular arteries was present in 94.6% (70/74) of the patients. According to the Meridian-RO trial in the Ryazan region, endothelial dysfunction had been found in 51.2% (n = 341) of women and 52.4% (n = 300) of men, whereas the Krasnodar regional population data had shown it in 68.4% (n = 353) of women and 71.7% (n = 253) of men. Conclusion: The prevalence of endothelial dysfunction in the patients with solid malignancies, who have not undergone any chemo- or radiation therapy, is significantly higher than in the population of comparable age, conventional cardiovascular risk factors, and comorbidities. No significant increase of vascular stiffness was identified.
背景:内皮功能障碍被认为是心血管疾病的早期标志之一。它被认为是接受辅助和新辅助化疗的患者心血管并发症的潜在预测因子。目的:估计实体癌患者中内皮功能障碍的患病率,与没有任何恶性肿瘤的个体相比。材料和方法:这项观察性研究包括74例实体恶性肿瘤患者,主要是胃肠道。在多化疗前,所有患者均检查小动脉和大动脉内皮功能(AngioScan-01, Fiton, Russia)和外周动脉硬度(脉搏波轮廓分析和闭塞试验)。将结果与俄罗斯人群内皮功能障碍试验子午- ro(梁赞地区)和克拉斯诺达尔地区农村人群试验的结果进行比较。结果:64.9%(48/74)的癌症患者存在血管舒张受损和小动脉张力受损,94.6%(70/74)的癌症患者存在较大肌肉动脉血管舒张受损。根据梁赞地区的Meridian-RO试验,51.2% (n = 341)的女性和52.4% (n = 300)的男性发现了内皮功能障碍,而克拉斯诺达尔地区的人口数据显示,68.4% (n = 353)的女性和71.7% (n = 253)的男性发现了内皮功能障碍。结论:未接受任何化疗或放疗的实体恶性肿瘤患者内皮功能障碍的患病率明显高于同龄人群、传统心血管危险因素和合并症。没有发现血管僵硬度明显增加。

Background: There have been a big number of studies assessing the efficacy of delayed coronary artery stenting (DCAS) in the prevention of no-reflow microvasculature injury compared to the standard immediate coronary artery stenting (ICAS) in ST-segment elevation myocardial infarction (STEMI). However, the results of these studies are contradictory in a lot of ways. Aim: To summarize studies on the assessment of DCAS in the prevention of no-reflow compared to the standard ICAS. Materials and methods: We performed a systematic literature search in PubMed, Google Scholar, and eLIBRARY.RU databases. The analysis included 17 studies with a total sample of 3505 patients. The comparative analysis included angiography-based endpoints prevalence of no-reflow (thrombolysis in myocardial infarction, TIMI 3 and myocardial blush grade, MBG 2, corrected TIMI frame count, CTFC) and clinical endpoints of all-cause mortality, cardiovascular mortality, major adverse cardiac events (MACE), recurrent myocardial infarction and recurrent revascularization. In addition, the analysis included the assessment of ST-elevation resolution, left ventricular ejection fraction values in the delayed post-intervention period and between-group differences. Results: The no-reflow phenomenon was significantly less frequent in the DCAS groups for the following parameters: epicardial flow TIMI 3 (odds ratio (OR) 2.00; 95% confidence interval (CI) 1.492.69; p 0.00001; I = 16%), myocardial perfusion MBG 2 (OR 4.69; 95% CI 1.9811.14; p = 0.0005; I = 59%), CTFC (mean difference (MD) 10.29; 95% CI 0.9619.62; p = 0.03; I = 96%). The analysis of secondary endpoints showed that MACE were less frequent in the DCAS groups (OR 1.29; 95% CI 1.041.60; p = 0.02; I = 42%), the difference becoming more significant in the studies with high initial thrombotic burden (TTG 3) (OR 1.83; 95% CI 1.282.62; p = 0.0009; I = 41%). The most clinically significant decrease of the MACE rate was found in 5 studies (n = 656) with high initial thrombotic burden (TTG 3) and mean time to repeated intervention from 4 to 7 days (OR 3.15; 95% CI 1.865.32; p 0.0001; I = 0%). The reverse trend for a benefit in the ICAS group was observed in the studies with a high initial thrombotic burden (TTG 3) and mean time to recurrent intervention of 48 hours (OR 0.60; 95% CI 0.301.19; p = 0.14; I = 20%). The ICAS and DCAS groups did not differ in overall mortality (p = 0.31), cardiovascular mortality (p = 0.49), repeated revascularization (p = 0.66), and ST resolution of 70% (p = 0.65). In the DCAS groups, there was an obvious trend to lower incidence of recurrent myocardial infarction (OR 1.28; 95% CI 0.951.73; p = 0.10; I = 0%), as well as to higher myocardial mass during the deferred analysis of left ventricular ejection fraction (OR -0.79; 95% CI -1.61 -0.04; p = 0.06; I = 36%). Conclusion: Deferred coronary artery stenting is an effective method for prevention of no-reflow. In patients with extended coronary thrombosis (TTG
背景:在st段抬高型心肌梗死(STEMI)中,与标准即刻冠状动脉支架植入术(ICAS)相比,已有大量研究评估延迟冠状动脉支架植入术(DCAS)在预防无再流微血管损伤方面的疗效。然而,这些研究的结果在很多方面是相互矛盾的。目的:总结DCAS与标准ICAS在预防无回流方面的研究进展。材料和方法:我们在PubMed、Google Scholar和eLIBRARY进行了系统的文献检索。俄文数据库。该分析包括17项研究,总样本为3505名患者。比较分析包括基于血管造影的无血流再流流行率(心肌梗死溶栓、TIMI 3和心肌红肿分级、MBG 2、校正后的TIMI框架计数、CTFC)和全因死亡率、心血管死亡率、主要不良心脏事件(MACE)、复发性心肌梗死和复发性血管重建术的临床终点。此外,分析包括评估st段抬高分辨率,干预后延迟期间左室射血分数值和组间差异。结果:DCAS组心外膜血流TIMI 3(优势比(OR) 2.00;95%置信区间(CI) 1.492.69;p 0.00001;I = 16%),心肌灌注mbg2 (OR 4.69;95% ci 1.9811.14;P = 0.0005;I = 59%), CTFC (mean difference (MD) 10.29;95% ci 0.9619.62;P = 0.03;I = 96%)。次要终点分析显示,DCAS组MACE发生率较低(OR 1.29;95% ci 1.041.60;P = 0.02;I = 42%),在高初始血栓负担(ttg3)的研究中,差异变得更加显著(OR 1.83;95% ci 1.282.62;P = 0.0009;I = 41%)。5项研究(n = 656)发现MACE率的临床显著下降,这些研究的初始血栓负担(ttg3)高,重复干预的平均时间为4至7天(OR 3.15;95% ci 1.865.32;p 0.0001;I = 0%)。在高初始血栓负担(ttg3)和平均复发干预时间为48小时(OR 0.60;95% ci 0.301.19;P = 0.14;I = 20%)。ICAS组和DCAS组在总死亡率(p = 0.31)、心血管死亡率(p = 0.49)、反复血运重建术(p = 0.66)和ST分辨率70% (p = 0.65)方面均无差异。在DCAS组中,心肌梗死复发率有明显降低的趋势(OR 1.28;95% ci 0.951.73;P = 0.10;I = 0%),以及左室射血分数延迟分析时心肌质量升高(OR -0.79;95% ci -1.61 -0.04;P = 0.06;I = 36%)。结论:延期冠状动脉支架置入术是预防无血流循环的有效方法。在延伸性冠状动脉血栓形成(ttg3)和STEMI患者中,与立即置入术相比,DCAS技术与复发干预时间为4 ~ 7天的患者相比,降低了MACE的发生概率。

Targeted treatment with somatostatin analogues (SA) in acromegaly and neuroendocrine neoplasms may have some benefits compared to curative treatments, because these agents decrease excessive hormone secretion and exert a tumor-suppressive effect. Monotherapy and combination therapy with SA is well tolerated and bears no risk of debilitating iatrogenic complications. In acromegaly caused by somatotropin producing pituitary tumor, first generation SA are treatment of choice after non-radical adenomectomy, as well as in the cases when patients reject surgery. Treatment efficacy depends on the pathomorphological types of somatotropic tumors, which are different in their receptor phenotype, clinical scenario and proliferative activity. The first generation SA are successfully used for medical treatment of other pituitary tumors (thyrotropic, corticotropic, gonadotropic, lactotropic with resistance to dopamine agonists), as well as for adjuvant therapy of neuroendocrine and non-endocrine neoplasms and elimination of various gastrointestinal disorders. The anti-secretory and anti-tumor effects of SA have been proven for gastroenteropancreatic tumors (carcinoid syndrome, vipomas, gastrinomas, insulinomas, glucagonomas, somatostatinomas). Targeted selection of patients for treatment with first generation SA based on the receptor phenotypes of malignant cells would facilitate more rapid achievement of biochemical remission, improvement of quality of life and survival.
与根治性治疗相比,用生长抑素类似物(SA)靶向治疗肢端肥大症和神经内分泌肿瘤可能有一些好处,因为这些药物可以减少过多的激素分泌并发挥肿瘤抑制作用。单药治疗和SA联合治疗耐受性良好,没有使人衰弱的医源性并发症的风险。在由促生长激素产生的垂体肿瘤引起的肢端肥大症中,第一代SA是在非根治性腺瘤切除术后以及患者拒绝手术的情况下的首选治疗方法。治疗效果取决于促生长肿瘤的病理形态类型,这些类型在受体表型、临床情况和增殖活性方面都有所不同。第一代SA已成功用于其他垂体肿瘤(促甲状腺、促皮质、促性腺、嗜乳且对多巴胺激动剂有抗性)的医学治疗,以及神经内分泌和非内分泌肿瘤的辅助治疗和各种胃肠疾病的消除。SA的抗分泌和抗肿瘤作用已被证实用于胃肠胰腺肿瘤(类癌综合征、恶性瘤、胃泌素瘤、胰岛素瘤、胰高血糖素瘤、生长抑素瘤)。根据恶性细胞的受体表型有针对性地选择第一代SA治疗的患者,将有助于更快地实现生化缓解,改善生活质量和生存率。

Background: Transcutaneous transhepatic endobiliary forceps biopsy is an accepted method for verification of extrahepatic cholangiocarcinoma, but its sensitivity ranges from zero to 94%. In the recent years, optical coherence tomography (OCT) has been actively used to diagnose malignancies. Aim: To assess diagnostic accuracy of the OCT-assisted intraductal forceps biopsy in patients with Klatskin tumor. Materials and methods: From 2013 to 2021, 161 patients with preliminary diagnosis of Klatskin tumor were seen in Russian Scientific Center of Radiology and Surgical Technologies named after Academician A.M. Granov. The retrospective study included 48 patients and 51 procedures of the forceps biopsy. In 14 (29%) patients of the main study group, the biopsy procedure was performed with OCT assistance, whereas the control group (34 patients, 71%) had their biopsies without the OCT. Results: All procedures were technically successful. In the main and in the control study groups, sensitivity was 92.3% versus 73.3% (p = 0.32) and specificity 100% versus 85.7% (p = 0.88), respectively. Malignant neoplasm of the biliary tract was found in 13 cases versus 23 in the control group, with the degree of the tumor differentiation being determined in 64.3% (n = 9), versus 48.7% (n = 18) (p = 0.89), respectively. There were no adverse events associated with OCT and biopsy sampling in the main study group. In the control group, 4/37 procedures (10.8%) were associated with hemobilia, which was successfully treated conservatively within 24 hours without any prolongation of the hospital stay. Conclusion: Our preliminary results indicate that antegrade endobiliary forceps biopsy is a safe and informative technique.

Background: Despite advanced in interventional and medical treatment, mortality after myocardial infarction (MI) remains high, which necessitates the search for predictors of poor outcome. An association between the gene CYP2C19 alleles with lower functional activity and the rates of cardiovascular events has been found. In a number of studies, negative impact of the *2 and *3 alleles of this polymorphic gene on the post-infarction course was shown. However, in most of these studies the patients were followed up from 3 months to 1 year. Aim: To evaluate the effect of CYP2C19 gene polymorphism (*2, *3) on the long-term prognosis in patients with a history of ST-segment elevation myocardial infarction (STEMI). Materials and methods: This open-label prospective two-center study included 145 patients aged 45 to 75 years with a history of STEMI. For 1 year from STEMI on, all the patients were taking medications recommended for outcome improvement, such as statins, clopidogrel as a component of dual antiplatelet therapy, beta-blockers, angiotensin converting enzyme inhibitors. The outcomes were assessed at 12 months by the endpoints of cardiovascular death and recurrent non-fatal MI, and at 5 years by the endpoints of overall mortality and recurrent non-fatal MI. Results: During one year of the follow up, 7 of 145 patients (4.8%) died from cardiovascular causes. Recurrent MI occurred in 8.3% (n = 12) of the patients. The carriers of *1*2 and *1*3 genotypes of the polymorphic CYP2C19 gene were 3.27-fold more likely to experience recurrent MI within 1 year, compared to the carriers of other genotypes (relative risk = 3.27 [95% confidence interval 1.03; 10.36], p = 0.03). After 5 years of the follow up, this association has disappeared. No influence of the assessed polymorphisms on overall and cardiovascular mortality was found (p 0.05). One hundred and seven (107) patients were followed up for 5 years; 14 (13.0%) of them died, other 15 patients (14.0%) had recurrent MIs. Conclusion: *2 and *3 alleles of the polymorphic CYP2C19 gene responsible for the metabolism of clopidogrel, are risk factors of an unfavorable 12-month outcome after STEMI. Subsequently, the influence of the CYP2C19 gene polymorphism on the outcomes evades and is not associated with a 5-year prognosis. To improve post-STEMI outcomes at 1 year, it is necessary to implement the earliest personalized approached to antiplatelet treatment based on the results of the CYP2C19 gene polymorphism analysis.
背景:尽管介入治疗和医学治疗取得了进展,但心肌梗死(MI)后的死亡率仍然很高,这就需要寻找不良预后的预测因素。功能活性较低的基因CYP2C19等位基因与心血管事件发生率之间存在关联。在许多研究中,该多态基因的*2和*3等位基因对梗死后病程有负面影响。然而,在这些研究中,大多数患者的随访时间为3个月至1年。目的:探讨CYP2C19基因多态性(*2,*3)对st段抬高型心肌梗死(STEMI)患者长期预后的影响。材料和方法:这项开放标签前瞻性双中心研究纳入145例年龄在45 - 75岁之间有STEMI病史的患者。从STEMI开始的1年时间里,所有患者都服用了改善预后的推荐药物,如他汀类药物、氯吡格雷作为双重抗血小板治疗的组成部分、受体阻滞剂、血管紧张素转换酶抑制剂。12个月时以心血管死亡和复发性非致死性心肌梗死为终点,5年时以总死亡率和复发性非致死性心肌梗死为终点。结果:在1年的随访中,145例患者中有7例(4.8%)死于心血管原因。8.3% (n = 12)的患者发生心肌梗死复发。多态CYP2C19基因*1*2和*1*3基因型携带者1年内心肌梗死复发的可能性是其他基因型携带者的3.27倍(相对危险度= 3.27[95%可信区间1.03;10.36], p = 0.03)。经过5年的随访,这种联系消失了。未发现评估的多态性对总体死亡率和心血管死亡率有影响(p 0.05)。107例患者随访5年;死亡14例(13.0%),复发15例(14.0%)。结论:参与氯吡格雷代谢的多态CYP2C19基因*2和*3等位基因是STEMI术后12个月预后不良的危险因素。随后,CYP2C19基因多态性对预后的影响被回避,并且与5年预后无关。为了改善stemi后1年的预后,有必要根据CYP2C19基因多态性分析的结果,实施最早的个性化抗血小板治疗。

Coronavirus infection (COVID-19) is usually characterized by respiratory symptoms, but can have a wide range of clinical manifestations. The growing interest is focusing on the short-term and long-term immune-mediated sequelae triggered by the COVID-19. One of these complications is post-infectious arthritis, classified by some authors as reactive. This paper summarizes and analyzes 25 clinical cases of COVID-19-associated acute arthritis that have been published from January 2020 to November 2021. The mean age of the patients was 46 14 years, with the disease being more prevalent in men than in women. Joint lesions were mono- or polyarticular, with predominant involvement of the joints of the lower extremities. HLA-B27 antigen was determined in 13 of 25 patients and was found in 30% of cases. Like many other viral diseases, the severe acute respiratory syndrome 2 caused by coronavirus can act as a causative agent or a trigger in the development of inflammatory arthritis in predisposed individuals. The post-infectious arthritis should be differentiated from diseases that can manifest with a similar clinical presentation, which requires a complex of laboratory and instrumental studies. Non-steroidal anti-inflammatory drugs and glucocorticosteroids are successfully used in the treatment. The number of cases of post-COVID-19-arthritis is increasing, which urges further studies of its pathophysiology, diagnosis and treatment regimens.
冠状病毒感染(COVID-19)通常以呼吸道症状为特征,但可具有广泛的临床表现。人们越来越关注COVID-19引发的短期和长期免疫介导的后遗症。其中一种并发症是感染后关节炎,被一些作者归类为反应性关节炎。本文对2020年1月至2021年11月发表的25例新冠肺炎相关急性关节炎临床病例进行总结分析。患者的平均年龄为46,14岁,男性比女性更普遍。关节病变为单关节或多关节,主要累及下肢关节。25例患者中有13例检测到HLA-B27抗原,30%的患者检出。像许多其他病毒性疾病一样,由冠状病毒引起的严重急性呼吸系统综合征可以作为易感人群炎症性关节炎发展的病原体或触发因素。感染后关节炎应与具有相似临床表现的疾病区分开来,这需要复杂的实验室和仪器研究。非甾体抗炎药和糖皮质激素已成功用于治疗。新型冠状病毒肺炎后关节炎病例不断增加,迫切需要对其病理生理、诊断和治疗方案进行进一步研究。
