The aim of the pilot study of a group of adolescents with H. pylori infection was to study the preliminary data obtained on the rs602662 locus of the FUT2 gene and to establish its role in the realization of clinical manifestations of chronic gastritis, gastric ulcer and duodenal ulcer associated with H. pylori.Methods: The study included 91 patients. The study for the presence of the polymorphic locus rs602662 of the FUT2 gene was carried out by the standard TaqMan PCR method on a Real-Time CFX96 Touch amplifier. The duration of the study was 6 months.Results: The main group included 25 adolescents aged 16 to 17 years 11 months, the control group included 20 patients. Patients infected with H. pylori more often noticed symptoms of dyspepsia - in 36%, compared with the control group - 9.7%. The presence of a family history in the main group for associated diseases had a significant difference, χ2 = 4.97, p <0.05.To assess the contribution of the genotype of the rs602662 locus of the FUT2 gene to the risk of clinical manifestations in H. pylori infection, the main group was divided into subgroups. In the distribution of alleles in these groups, statistically significant differences were revealed.Allele “A” has a protective effect against the onset of clinical symptoms of dyspepsia. The odds ratio (OR) with the carriage of allele “A” (genotypes A / A and G / A versus G / G) to have clinical symptoms with a positive H. pylori status was 0.175 (CI = [0.049-0.625] chi2 = 7.79 p = 0.0053).Conclusion. As a result of the study, we were unable to identify a significant association of alleles and genotypes of the rs602662 locus of the FUT2 gene with clinical manifestations of H. pylori infection. At the same time, carriers of the A allele have a pronounced association with the absence of clinical symptoms in patients with a positive H. pylori infection status of 0.175 (C.I. = [0.049-0.625] chi2 = 7.79 p = 0.0053).

Background. The effective treatment of the hand-foot syndrome is a necessary component of the complex treatment of patients receiving antitumor therapy with multikinase inhibitors. Aims. The assessment of a new effective method for the treatment of palm-plantar syndrome in patients receiving multi-kinase inhibitors. Materials and methods. There are 27 patients received antitumor treatment with multi-kinase inhibitors and had clinical manifestations of the hand-foot syndrome (HFS) for observation. The main group (14 patients) used a combination of an alpha-lipoic acid at a dose of 600 mg per day per os and an ointment containing 0.005% calcipotriol and 0.05% betamethasone dipropionate 2 times a day. The control group, included 13 patients, used a combination with a cream containing 10% urea and ointment containing 0.05% betamethasone dipropionate. Results. After a week of treatment, the regression of the skin process was observed in both groups, but it was more evident in the main group: significant differences in severity of erythema, paresthesia, pain and burning sensation, the Dermatological Life Quality Index (DLQI) were observed at this stage of therapy (p < 0.05). After 2 weeks of therapy: a more positive trend in the main group in terms of erythema, paresthesia and burning, but the most significant difference is DLQI – 17.4 in the main group and 22.8 in the control group (p < 0.0001). At the end of the 3rd week of therapy: differences with the main characteristics of erythema, desquamation, paresthesia (p < 0.0008), pain (p < 0.0001), DLQI (p < 0.0001). At the end point of the study (after 4 weeks of therapy), significant differences were found in reducing the symptoms and the main parameters for evaluating the effectiveness of DLQI in patients of the main group with a reliability of p < 0.0001. The high correlation of DLQI was found with erythema, pain, burning, paresthesia and desquamation. Conclusions. The treatment of the hand-foot plantar syndrome combined using alpha-lipoic acid inside and topical therapy in the form of an ointment containing calcipotriol and betamethasone dipropionate, can be recommended for patients receiving targeted therapy with multi-kinaseinhibitors.

e17514 Background: Malignant pelvic tumors account for more than 25% of cancer incidence in Russia. Radiation therapy is the most common treatment for such patients; however, 10-15% of patients develop radiation-induced complications of the pelvic organs, and more effective treatments are required to manage these complications. Methods: The study included 30 patients with cervical cancer T3NхM0 after combination treatment. 7-10 months after combined radiation treatment (total radiation dose to the primary focus 80 Gy), patients developed erosive ulcerative radiation rectitis (RTOG grade 1 and 2). Patients were divided into 2 groups: main group (n = 15) – conservative treatment combined with LILEDR. Each course included 10 LILEDR sessions, the red spectrum λ = 640 nm on the cubital vein projection (exposure time 5 minutes, dose 6.86 J/cm2) and locally on the ulcerated zones (exposure time 3 minutes, dose 3.96 J/cm2). Patients received 2 LILEDR courses with a 1-month interval. The control group received only conservative therapy. Results: Main clinical manifestations of rectitis (tenesmus, bloody mucous discharge) disappeared in the main group already on the 3-4th day of the first course, epithelialization of ulcerative defects occurred in a shorter period of 7-10 days. Soft superficial scars not causing rectal stenosis formed at the site of the ulcer by the end of LILEDR courses. The control group showed long periods of the ulcer epithelialization up to 30 days, late remission and a lingering recurrent character of the disease. Conclusions: LILEDR in combination with the main conservative therapy allows rapid managing with the clinical symptoms of radiation rectitis and regression of disorders developed after the complex treatment, which improves the quality of life of patients and shortens the rehabilitation period.

Purpose. To study the effect of undifferentiated connective tissue dysplasia (UCTD) on the clinical features of the course of school myopia. Material and methods. The object of study – 120 children (240 eyes) aged 12–15 years with moderate axial myopia. In addition to standard examination methods, computer accommodography and measure of convergence were carried out. Two observation groups were formed: the main – 80 people (160 eyes) with clinical manifestations of UCTD, the control – 40 people (80 eyes) without clinical manifestations of UCTD. According to the severity of clinical manifestations of UCTD in the main group, 3 subgroups were distinguished: 1–A – 25 children (50 eyes) with a weak degree of UCTD, 1–B – 38 children (76 eyes) with a moderate degree of UCTD, 1–C – 17 children (34 eyes) with a pronounced degree of UCTD. Results. Locomotor syndrome prevails in the structure of UCTD in children of the main group. A comparative analysis of the frequency of peripheral retinal degeneration revealed that most often they are detected in children with myopia associated with UCTD. In children of the main observation group, weakness of accommodation prevails in the structure of accommodation disorders (p<0,05). In the general population of examined in 39 children (32,5%), the presence of esophoria of varying degrees of compensation was diagnosed. A statistically significant difference was revealed between the control group and the subgroup of children with myopia associated with a pronounced degree of UCTD. Conclusion. Phenotypic signs of locomotor syndrome prevails in the structure of UCTD. School myopia in children with UCTD is characterized by: an increase in the frequency of peripheral retinal degeneration in 2,9 times; an increase in the proportion of children with a weakness of accommodation – in 1,7 times and violations between accommodation and convergence – in 2,2 times, compared with children with myopia without UCTD.

AbstractObjectiveThis study aimed to examine nasal mucociliary clearance time in patients with Helicobacter pylori infection.MethodsFifty patients who were newly diagnosed with H pylori infection using gastric biopsy in the gastroenterology out-patient clinic, and 50 age- and gender-matched healthy adults who were admitted to the otorhinolaryngology out-patient clinic, were included in this study. After an otorhinolaryngological examination (anterior rhinoscopy and nasal endoscopic examination), the nasal mucociliary clearance time of each subject was calculated using the saccharine test.ResultsThe mean mucociliary clearance time was 06:29 ± 3:31 minutes (range, 00:55–15:19 minutes) in the control group and 10:12 ± 06:09 minutes (range, 01:28–32:00 minutes) in the study group. Comparisons of the two groups revealed a statistically significant difference (p = 0.002).ConclusionNasal mucociliary clearance time was significantly increased in patients with H pylori infection. The results suggest that H pylori infection may have an unfavourable effect on nasal mucociliary clearance.

Background: Amplification of inflammation in acute exacerbation of chronic obstructive pulmonary disease (COPD) increases inflammatory mediators and oxidative stress in the airways, pulmonary and systemic circulation that are characterized by increased plasma level of IL-6 and MDA, resulting in worsening of clinical symptoms. Xanthones in mangosteen pericarp have anti-inflammatory and antioxidant effects, potentially as an adjuntive therapy in acute exacerbations of COPD. Methods: The aim of this study was to determine the effect of mangosteen pericarp extract to clinical improvements, plasma level of IL-6 and MDA of acute exacerbation COPD patients. A clinical trial of experimental with pretest and posttest was conducted on 34 acute exacerbation of COPD patients in Dr. Moewardi Hospital Surakarta and Dr. Ario Wirawan Lung Hospital Salatiga from April until May 2016. The sample was taken by consecutive sampling. Subjects were divided by randomized double blind technique into the treatment group (n=17) received mangosteen pericarp extract 2x1100mg/day and control group (n = 17) received placebo. Clinical improvements were measured in CAT score and length of stay. CAT score, plasma level of IL-6 and MDA were measured on admission and at discharge. Length of stay based on the number of days of care in hospitals. Results: There was significant difference (p=0,011) towards decreased of IL-6 plasma level between treatment group (-2,17 ± 3,46 pg/ mL) and control group (+1,67 ± 6,81 pg/mL). There were no significant difference towards decreased of length of stay (p=0,34) between treatment group (4,12 ± 1,54 days) and control group (5,24 ± 2,49 days), towards decreased of CAT score (p=0,252) between treatment group (-19,18 ± 3,96) and control group (-18,24 ± 2,75), and towards decreased of MDA plasma level (p=0,986) between treatment group (+0,03 ± 0,36μmol/L) and control group (+0,35 ± 1,58). Conclusions: The addition of mangosteen pericarp extract 2x1100mg/day during hospitalization was significantly lowered plasma levels of IL-6, but were not significant in lowering the CAT score, shortening the length of stay, and reducing the increase in plasma level of MDA.

Врожденные пороки сердца (ВПС) являются ведущей патологией среди всех пороков и аномалий развития плода. Известно, что тератогенный эффект ксенобиотика будет максимально представлен при нарушенных иммунных взаимодействиях в системе мать-эмбрион . Неоднократно показано, что женский гомозиготный генотип HLA-G 3UTR 14-bp ins/ins ассоциирован с репродуктивными потерями. Цель исследования. Изучить распределение аллелей и генотипов генов биотрансформации ксенобиотиков у женщин, имеющих детей с ВПС, носительниц вариантных генотипов HLA-G 3UTR 14-bp ins/del. Материал и методы. Обследованы 103 женщины, у которых дети при рождении имели врожденный порок сердца без хромосомных заболеваний и родословной историей, а также 103 женщины (контрольная группа), родивших двух здоровых детей и более. Типирование полиморфных сайтов генов HLA-G 3UTR 14-bpins/del, GSTM1 (rs74837985), CYP1A1 (rs1048943) CYP1A2 (rs35694136, rs762551) GSTT1 (rs2266633, rs2266637, rs2234953) GSTP1 (rs6591256, rs1695, rs1871042, rs1793068), GATA 6 (rs10454095) проводили методом RT-PCR. Результаты. Показано, что у женщин основной группы, являющихся носительницами гомозиготного генотипа 14-bp ins/ins HLA-G 3UTR, статистически значимо чаще встречались гетерозиготные генотипы GSTP1 (rs6591256) A/G (р0,01 отношение шансов ОШ5,1, 2,5710,27), GSTP (rs1793068) G/T (р0,01 ОШ5,1, 2,5710,27), CYP1A2 (rs762551) A/C (р0,01 ОШ6,81, 3,3513,73) и гомозиготный минорный генотип GSTP1 (rs1871042) T/T (р0,001 ОШ7,32, 3,6214,76) по сравнению с группой контроля. В основной группе женщин G/G rs74837985 GSTM1 статистически значимо реже (р0,01 ОШ 0,20, 0,06-0,59) встречался у носительниц 14-bp ins/ins HLA-G 3UTR по сравнению с носительницами гетерозиготного генотипа 14-bp ins/del HLA-G 3UTR. Заключение. В ходе исследования установлено, что при одновременном носительстве мутантных аллелей HLA-G и генов системы транформации ксенобиотиков риски рождения детей с дефектом межжелудочковой перегородки выше, чем при носительстве изолированных мутаций.Congenital heart defects (CHD) are the leading pathologies among all congenital malformations and fetal development abnormalities. It is known that the teratogenic effect of xenobiotic will be maximally presented in the case of disturbed immune interactions in the mother-embryo system. It has been repeatedly shown that the female homozygous genotype HLA-G 3UTR 14-bp ins/ins is associated with reproductive losses. The purpose of this study was to study the distribution of alleles and genotypes of xenobiotic biotransformation genes in women with children with CHD, carriers of variant HLA-G 3UTR 14-bp ins/del genotypes. Material and method: It was examined 103 women whose children had a ventricular septal defect (VSD) without chromosomal diseases and a pedigree history at birth, and 103 women (control group) who gave birth to two or more healthy children. The typing of polymorphic sites of the genes HLA-G 3UTR 14-bp ins/del, GSTM1 (rs74837985), CYP1A1 (rs1048943) CYP1A2 (rs35694136, rs762551) GSTT1 (rs2266633, rs2266637, rs2234953) GSTP1 (rs6591256, rs1695, rs1871042, rs1793068), GATA 6 (rs10454095) was performed by the RT-PCR method. Mathematical processing was carried out using the application software STATISTICA 8.0 (StatSoftInc., USA) and SNPstats. Results: It was shown that the heterozygous genotypes GSTP1 (rs6591256) A / G (p0.01, OR5.1 (2.5710.27)), GSTP (rs1793068) G / T (p0.01, OR5.1 (2.5710.27)), CYP1A2 (rs762551) A/C (p0.01, OR6.81 (3.3513.73)) and the homozygous minor genotype GSTP1 (rs1871042) T/T (p0.001, OR7.32 (3.6214.76) ) were statistically significantly more frequent in the main group of women who are carriers of the homozygous genotype 14-bp ins/ins HLA-G 3UTR, in comparison with the control group. In the main group of women G/G rs74837985 GSTM1 statistically significantly less (p0.01, OR0.20 (0.060.59)) was found in carriers of 14-bp ins / ins HLA-G 3UTR, in comparison with carriers of the heterozygous genotype 14-bp ins/del HLA-G 3UTR. Conclusion: It was found that with the simultaneous carrier of the mutant alleles of HLA-G and the genes of the xenobiotics transformation system, the risk of having children with VSD is higher, compared with the carriage of isolated mutations.

Aim. To assess the effectiveness of the use of the antiviral drug enisamium iodide in the complex treatment of acute respiratory viral infections (ARVI) caused by various pathogens in routine clinical practice. Materials and methods. А prospective randomized study included 134 patients who were treated in the epidemic season of influenza and ARVI in 20182019. All patients were examined for the presence of influenza A and B viruses, respiratory syncytial virus, human metapneumovirus, parainfluenza virus, coronaviruses, rhinoviruses, adenoviruses in nasopharyngeal swabs by PCR. Patients of the main group received enisamium iodide along with symptomatic therapy, the control group received only symptomatic therapy. The primary parameter of the effectiveness of therapy was evaluated on the scale of the general severity of the manifestations of ARVI (Total Symptom Score TSS) from the 2nd to the 4th day and by the secondary criteria of effectiveness: assessment of the duration of ARVI, the severity of fever, the proportion of patients with normal body temperature, the duration of the main clinical symptoms of acute respiratory viral infections, the proportion of patients in whom complications requiring antibiotics were noted, the dynamics of interferon status on the 6th day. To conduct a statistical analysis, depending on the efficiency parameter, the ANCOVA method with a fixed group factor and an initial score on the TSS severity scale was used as covariates, a criterion for comparing quantitative indicators in two independent groups. Results. According to the results of the analysis of the primary efficacy parameter, the median (interquartile range) of the average score on the scale of the general severity of ARVI manifestations in the main group was 4.33 (3.675.83), in the comparison group 6.00 (4.677.25; p0.001). The duration of systemic and local manifestations of acute respiratory viral infections was statistically significantly less in the main group (p=0.002 and p=0.019, respectively). Prescription of additional therapy was required in 2 (2.9%) patients of the main group (patients taking enisamium iodide), compared with 8 (11.9%) patients in the control group. Serum levels of interferon  and interferon  on the last day of treatment were statistically significantly higher in patients of the main group compared with the control group (p0.001). Treatment (excellent) was evaluated by 42 (62.7%) patients, while in the control group only 17 (25.8%) patients gave similar ratings. Both patients (p0.001) and doctors (p0.002) rated therapy tolerance better in the study group. Conclusion. The results confirmed the safety and effectiveness of enisamium iodide as a treatment for ARVI and influenza. The antiviral, interferonogenic and anti-inflammatory properties of the drug are involved in the formation of an antiviral response and reduce the risk of complications, which makes it possible to reduce the number of symptomatic agents used.

Abstract Background Helicobacter pylori (H. pylori) infection is the most important risk factor for gastritis and peptic ulcer. However, factors other than H. pylori are involved in its pathogenesis. In the current study, we aimed to compare the clinical manifestations and endoscopic and histopathological findings of patients with and without H. pylori infection. Methods In this cross-sectional study, 233 patients with dyspepsia, referred for endoscopy, were examined regarding the presence of H. pylori infection. During an endoscopic exam, 5 biopsy specimens were taken from the stomach. The criteria for the presence of H. pylori infection was the presence and identification of bacteria in pathology. Two groups of H. pylori-positive and H. pylori-negative patients were compared regarding their demographic, endoscopic, and pathological findings. Results Of 233 patients, 154 (66.1%) were non-smokers, 201 (86.3%) were not alcohol users, and 153 (65.7%) used tap water. The most common symptom, reported in 157 (67.4%) patients, was epigastric pain. There was a significant difference between patients with and without H. pylori infection in terms of the educational status, occupational status, family history of gastrointestinal cancer, and some gastrointestinal symptoms. Also, there was a significant relationship between the endoscopic and pathological findings of patients with H. pylori. Conclusions The results of the present study revealed that H. pylori infection was not associated with sex, alcohol consumption, or non-steroidal anti-inflammatory drug use. The role of H. pylori in the pathophysiology of peptic ulcer was clarified. Also, there was a significant difference in the endoscopic and pathological findings of patients with H. pylori.
