Abstract
BACKGROUND Fabry disease (FD) is a rare hereditary multisystem disease caused by variants of the GLA gene. Determination of GLA gene variants and identification of genotype-phenotype correlations allow us to explain the features of FD associated with predominant damage of one or another system, both in the classical and atypical forms of FD, as well as in cases with late manifestation and involvement of one of the systems. METHODS The study included 293 Russian patients with pathogenic variants of the GLA gene, which were identified as a result of various selective screening programs. Screening was carried out for 48,428 high-risk patients using a two-step diagnostic algorithm, including the determination of the concentration of the biomarker lyso-Gb3 as a first-tier test. Screening of atypical FD among patients with HCM was carried out via high-throughput sequencing in another 2427 patients. RESULTS 102 (0.20%) cases of FD were identified among unrelated patients as a result of the study of 50,855 patients. Molecular genetic testing allowed us to reveal the spectrum and frequencies of 104 different pathogenic variants of the GLA gene in 293 examined patients from 133 families. The spectrum and frequencies of clinical manifestations in patients with FD, including 20 pediatric patients, were described. Correlations between the concentration of the lyso-Gb3 biomarker and the type of pathogenic variants of the GLA gene have been established. Variants identified in patients with early stroke were described, and the association of certain variants with the development of stroke was established. CONCLUSIONS The results of a large-scale selective FD screening, as well as clinical and molecular genetic features, in a cohort of 293 Russian patients with FD are described.

Abstract
Successful therapy in a cohort with early onset Danon disease (DD) highlights the potential importance of earlier disease recognition. We present experience from the largest National Pediatric Center in Russia for cardiomyopathy patients. This report focuses on identification of early clinical features of DD in the pediatric population by detailed pedigree analysis and review of medical records. RESULTS: Nine patients (3 females) were identified with DD at the Russian National Medical Research Center of Children's Health ("National Pediatric Center") aged birth to 16 years. At presentation/evaluation: all patients had left ventricular hypertrophy (LVH), ECG features of Wolff-Parkinson-White (WPW), and an increase in hepatic enzymes (particularly lactate dehydrogenase (LDH)); three had marked increase in NT-proBNP; two had HCM with impaired LV function; one had LVH with LV noncompaction; five had arrhythmia with paroxysmal supraventricular and/or ventricular tachycardia. Two teenagers died at ages 16-17 from refractory heart failure and two underwent heart transplantation. All patients were found to have a pathogenic/likely pathogenic variant in the LAMP2 gene, six patients had no family history and a de novo evolvement was documented in 4/6 of those available for genetic tested. Retrospective review related to family background and earlier clinical evaluations revealed a definitive or highly suspicious family history of DD in 3, early clinical presentation with cardiac abnormalities (ECG, echo) in 3, and cerebral, hepatic and/or neuromuscular symptoms in 5. Abnormalities were detected 9,5 months to 5,8 years, median 3,5 years prior to referral to the National Pediatric Center. CONCLUSION: The earliest clinical manifestations of Danon disease occur in the first 12 years of life with symptoms of skeletal muscle and cerebral disease, raised hepatic enzymes, and evidence of cardiac disease on ECG/echo.

Abstract
INTRODUCTION Dystrophic epidermolysis bullosa (DEB) is one of the most severe forms of congenital epidermolysis bullosa and characterized by the formation of many surgical complications. Esophageal stenosis is a common complication of DEB and occurs in almost 76% of cases. Balloon dilatation (BD) under X-ray control is the main therapeutic technique, however conservative treatment is necessary to prevent restenosis. The use of the drug losartan is promising due to its antifibrotic effect through the suppression of transforming growth factor-β1 (TGF-β1). PURPOSE To evaluate the efficacy of losartan in the prevention of restenosis after BD of esophageal stenosis in children with DEB. MATERIALS AND METHODS The study included 19 children from 2 to 16 years old (mean age 9.2 ± 3.58 years) with DEB and X-ray confirmed esophageal stenosis. All children underwent BD. In the main group 9 children after BD have received losartan, in the control group of 10 children - only standard therapy. The observation period was 12 months. RESULTS In the main group, 1 child (11.1%) required repeated dilatation, in the control group - 4 children (40%). Indicators of nutritional deficiency (THINC scale) and the disease severity index (EBDASI) were significantly lower in the group of children treated with losartan. No undesirable actions of the drug were recorded. CONCLUSIONS In this study losartan showed its safety, contributed to a decrease in the restenosis frequency and an improvement in the nutritional status of children with DEB after BD. However, further studies are required to confirm its effectiveness. LEVEL OF EVIDENCE IV.

Abstract
INTRODUCTION Complete tracheal rings are a rare malformation that occurs in 1 out of 100,000 live births. It is rare, isolated tracheal or tracheobronchial anomaly developed due to abnormal cartilage growth with formation of complete ring and often resulting in airway stenosis. Slide tracheoplasty, as it was originally described by Tsang et al. and popularized by Grillo et al., overlaps stenotic segments of trachea, shortening trachea itself, thus, doubling the circumference and diameter of the stenotic area. MATERIALS AND METHODS We have performed slide tracheoplasty in 12 children during the period of 2019-2021 in thoracic surgery department of our center. Median age was 15 ± 21,1 months (2 months-6 years),median weight - 8,04 ± 4,75 kg (3-20,7 kg),tracheal lumen varied from 2.5 to 3.0 mm, stenosis length - from 40 to 70% of the trachea length. RESULTS Slide tracheoplasty was performed using central veno-arterial extracorporeal membrane oxygenation in 7 cases and using cardiopulmonary bypass in 5 cases. Concomitant heart disease was revealed in 5 children (pulmonary artery sling in 3 cases, ventricular septal defects - 1, aberrant subclavian artery -1). 5 children underwent one-stage correction of VSD: plastic VSD -1; left pulmonary artery reimplantation - 3; subclavian artery reimplantation - 1. All patients were on mechanical ventilation for 4,3 ± 2,78 days at postoperative period. Patients were discharged 16,3 ± 5,14 days after surgery. Satisfactory result of treatment in the form of respiratory failure relief was achieved in 10 patients. It was possible to increase the trachea lumen from 1.5 to 2 times in all cases. There were 2 (16,6%) fatal cases due to sepsis and multi-organ failure development. CONCLUSIONS Children with complete tracheal rings are very complicated patients with various comorbidities. Despite the advances in medicine, sometimes it is impossible to save lives of these children. The use of extracorporeal circulation (ECMO and bypass) allows us to safely perform reconstructive surgery on the trachea and save the child from respiratory failure manifestations. If needed, simultaneous correction of heart and tracheal defects is possible. Slide tracheoplasty allows to increase trachea lumen at least in 1.5-2 times. Mechanical ventilation is an unfavorable predictive factor for the outcomes of congenital tracheal stenosis management. LEVEL OF EVIDENCE III.

Abstract
Acinetobacter baumannii is a representative of the peak priority nosocomial pathogens capable of causing infections with high mortality and economic treatment costs. The purpose of our study was to determine a role of A. baumannii in blood-borne and central nervous system infections in children. We conducted a retrospective study of A. baumannii associated cases of bacteremia and CNS infection in children. A. baumannii strains were isolated from 17 children followed up with surgical pathology (congenital heart defects 24%, abdominal pathology 29%, severe combined trauma 29%) and with somatic diseases accompanied by antibacterial and/or glucocorticosteroid therapy 18%. The minimum inhibitory concentrations of antibiotics were determined by the broth microdilution method. Carbapenemase genes were detected by real time polymerase chain reaction. Biofilm formation genes were determined by PCR. Biofilms were grown using flat-bottomed polystyrene tablets, followed by coloring, fixation, elution and detection. Population diversity was assessed by the multilocus sequence typing. About a quarter of cases of bacteremia and central nervous system infection caused by A. baumannii had an unfavorable outcome. Resistance to carbapenems, aminoglycosides, fluoroquinolones was more than 70%. Carbapenemases of the OXA-23 (24%) and OXA-40 (41%) groups were identified. The study of biofilm production showed that A. baumannii isolates formed biofilms of varying intensity: weak biofilms (59%), moderate (35%) and strong (6%). During determining the sensitivity to meropenem for biofilm and planktonic forms of cultures, it was determined that the minimum inhibitory concentrations of meropenem were significantly higher for biofilms than for planktonic forms. The minimum inhibitory concentrations of meropenem for plankton cells ranged from 0.5 to 512 mg/l. While in biofilms the same microorganisms had in vitro minimum inhibitory concentrations of meropenem within 128 to 512 mg/l and higher. All isolates bore biofilm formation regulating genes: bfmR, bap and katE. The ompA gene was found in 94% strains, and the csuA/B gene was found in 88%. The population pattern of A. baumannii isolated from blood and cerebrospinal fluid of children was represented by nine different sequence types. Most of the isolates were represented by genotypes: ST944Oxf, ST1550Oxf, ST1104Oxf belonging to the international clonal line ICL6, and ST450Oxf, ST2063Oxf and ST1102Oxf of the international clonal line ICL2. Blood-borne and central nervous system infections associated with A. baumannii have a great importance in clinical practice. This microorganism is able to persist for a long time on biotic and abiotic surfaces, has a wide natural and acquired antibiotics resistance.

Abstract
Background There is a vast number of screening studies described in the literature from the beginning of the twenty-first century to the present day. Many of these studies are related to the estimation of Fabry disease (FD) morbidity among patients from high-risk groups, including adult patients with hypertrophic cardiomyopathy (HCM) and left ventricular hypertrophy (LVH). These studies show diverse detection frequencies (0–12%) depending on the methodology. Our study is the only example of large-scale selective FD screening based on the implementation of next-generation sequencing technology (NGS) as a first-level test to estimate FD morbidity in the Russian population over 18 years of age burdened with HCM. Methods The study included 1009 patients (578 males and 431 females), with a median age of 50 years, who were diagnosed with HCM according to current clinical guidelines. In the first stage of screening, all patients underwent molecular genetic testing (NGS method) of target regions. These regions included the coding sequences of 17 genes and mutations that can lead to the development of HCM. Lysosomal globotriaosylsphingosine (lyso-Gb3) concentrations and α-galactosidase A (α-gal A) enzyme activity were measured in the second stage of screening to reveal pathogenic or likely pathogenic variants in the GLA gene. Results We revealed 8 (0.8%) patients (3 (37.5%) males and 5 (62.5%) females) with an average age of 59 ± 13.3 years who had pathogenic, likely pathogenic variants and variants of uncertain significance (VUS) in the GLA gene (NM_000169.2) as a result of selective screening of 1009 Russian patients with HCM. FD was confirmed via biochemical tests in a male with the pathogenic variant c.902G > A, p.R301Q as well as in two females with likely pathogenic variants c.897C > A, p.D299E and c.1287_1288dup, p.*430Fext*?. These tests showed reduced enzymatic activity and increased substrate concentration. However, a female with the pathogenic variant c.416A > G, p.N139S and with normal enzymatic activity only had increased substrate concentrations. The revealed nucleotide variants and high values of biochemical indicators (lyso-Gb3) in these 4 patients allowed us to estimate the FD diagnosis among 1009 Russian patients with HCM. Mild extracardiac manifestations were observed in these four patients; however, both biochemical values within the reference range in females with the c.971T > G, p.L324W (VUS) variant. α-gal A activity and lyso-Gb3 concentrations were also within the normal range in two males with hemizygous variants, c.546T > C, p.D182D and c.640-794_640-791del (we regarded them as VUS), and in one female with the c.427G > A, p.A143T variant (with conflicting interpretations of pathogenicity). Conclusion The prevalence rate of FD among 1,009 adult Russian patients with HCM was 0.4%. We recommend FD screening among adult patients of both sexes with HCM and an undefined genetic cause via NGS method with subsequent analysis of α-gal A activity and lyso-Gb3 concentration in patients with pathogenic, likely pathogenic variants, and VUS. This strategy identifies patients with an atypical form of FD that is characterized by high residual activity of α-gal A, low concentrations of lyso-Gb3, and minor extracardiac manifestations.

Abstract
Lipopolysaccharide (LPS), a fragment of the bacterial cell wall, specifically interacting with protein complexes on the cell surface, can induce the production of pro-inflammatory and apoptotic signaling molecules, leading to the damage and death of brain cells. Similar effects have been noted in stroke and traumatic brain injury, when the leading factor of death is glutamate (Glu) excitotoxicity too. But being an amphiphilic molecule with a significant hydrophobic moiety and a large hydrophilic region, LPS can also non-specifically bind to the plasma membrane, altering its properties. In the present work, we studied the effect of LPS from Escherichia coli alone and in combination with the hyperstimulation of Glu-receptors on the functional state of mitochondria and Ca2+ homeostasis, oxygen consumption and the cell survival in primary cultures from the rats brain cerebellum and cortex. In both types of cultures, LPS (0.1–10 μg/ml) did not change the intracellular free Ca2+ concentration ([Ca2+]i) in resting neurons but slowed down the median of the decrease in [Ca2+]i on 14% and recovery of the mitochondrial potential (ΔΨm) after Glu removal. LPS did not affect the basal oxygen consumption rate (OCR) of cortical neurons; however, it did decrease the acute OCR during Glu and LPS coapplication. Evaluation of the cell culture survival using vital dyes and the MTT assay showed that LPS (10 μg/ml) and Glu (33 μM) reduced jointly and separately the proportion of live cortical neurons, but there was no synergism or additive action. LPS-effects was dependent on the type of culture, that may be related to both the properties of neurons and the different ratio between neurons and glial cells in cultures. The rapid manifestation of these effects may be the consequence of the direct effect of LPS on the rheological properties of the cell membrane.

Abstract
OBJECTIVES/HYPOTHESIS This study aimed to evaluate the olfactory status in children with laboratory confirmed SARS-CoV-2 using subjective and psychophysical methods. STUDY DESIGN Prospective clinical cross-sectional study. METHODS This is a prospective clinical cross-sectional study of 79 children with COVID-19. The 21st item of SNOT-22 questionnaire and odor identification test were used for smell assessment. Children were examined twice during the hospitalization, and a telephone survey was conducted 60 days after hospital discharge. RESULTS Immediately after confirmation of COVID-19, smell impairment was detected in 86.1% of children by means of the Identification test and in 68.4% of children by means of the survey (P = .010). After 5 days survey revealed a statistically significant decrease in the number of patients with hyposmia (41 out of 79, 51.9%). On the first visit, the mean Identification test score corresponded to "hyposmia" (9.5 ± 2.7), while on the second visit, the average value was 13.1 ± 1.9, which corresponded to "normosmia." According to the telephone survey, recovery of the olfactory function occurred within 10 days in 37 of 52 patients (71.2%), 11 to 29 days - in 12 children (23.1%), and later than 30 days - in three cases (5.7%). CONCLUSIONS In the pediatric population, olfactory dysfunction is an early and common symptom of COVID-19. There is a trend to quick recovery of olfactory function in children with COVID-19. The overwhelming majority of patients (94.3%) had no subjective olfactory complaints by the end of the first month. LEVEL OF EVIDENCE 4 Laryngoscope, 131:E2475-E2480, 2021.
