Introduction: IgA-dominant infection-related glomerulonephritis (IgA-IRGN) is a unique form of IRGN, which needs to be distinguished from IgA nephropathy (IgAN), due to overlapping clinical and pathological features. The key factor in the pathogenesis of IgAN is galactose-deficient IgA1 (Gd-IgA1). However, the mechanism of glomerular IgA deposition in patients with IgA-IRGN is unclear. Therefore, we evaluated whether Gd-IgA1 could be a useful biomarker to distinguish between these 2 diseases. Methods: A case-control study was conducted to analyze the clinical and pathological characteristics of 12 patients with IgA-IRGN. The intensity and distribution of glomerular Gd-IgA1 (KM55) staining in renal biopsies were assessed. The control group consisted of 15 patients diagnosed with IgAN and an additional 17 patients with glomerulopathy involving IgA deposition. Results: The main clinical manifestations of patients with IgA-IRGN were nephrotic-range proteinuria, hematuria, acute renal injury, and hypocomplementemia. Active lesions were the leading pathological feature, while focal segmental sclerosis was rare. Half of the patients exhibited hump-shaped subepithelial deposits. Glomerular KM55 staining was negative in 7 patients, trace in 4 patients, and 2+ in 1 patient. The median intensity of KM55 staining in IgA-IRGN patients was 0 (range 0∼2+), which was significantly lower than that of primary IgAN patients (median 2+, range 1+∼3+). The receiver operating characteristic analysis demonstrated that the optimal cutoff level to identify these 2 diseases was 0.5+. Conclusions: Glomerular KM55 staining intensity might be helpful to distinguish IgA-IRGN from primary IgAN. Weak or negative staining may favor IgA-IRGN. In addition, integrated analysis including clinical data, pathological findings, and prognostic information would further improve the differential diagnosis.

The susceptibility to the development and progression of inflammatory periodontal diseases, which depends on genetic and external factors (smoking, stress, oral hygiene), varies widely. In the development of these diseases, an important role is played not only by the presence of periodontal pathogenic microorganisms, but also by the presence of congenital or acquired immunodeficiency, immunoregulatory defects. The immune system plays a key role in the physiological and pathological processes of periodontal tissues. In this regard, IL17, produced by CD4+ Th cells, which has both Pro-inflammatory and protective activity, is of particular interest in the pathogenesis of periodontitis. The aim of study was to identify the relationship between polymorphic loci of the IL-17A (rs2275913) and MMP-1 (rs1799750) genes and clinical manifestations of chronic periodontitis in petrochemical workers. Dental examination was performed in 92 ethylene oxide production workers with chronic periodontitis and 74 patients with chronic periodontitis who did not come into contact with chemical factors (control group). Genotyping of polymorphisms rs2275913 of the IL17A gene and rs1799750 of the MMP1 gene was performed by allele-specific real-time polymerase chain reaction (PCR). Hygienic assessment of the degree of air pollution of the working area with harmful substances was carried out by gas chromatography according to the guidelines for the determination of harmful substances in the air № 5098-89, № 3119-84. When comparing the results of studies of both groups, there were no statistically significant differences in the frequency distributions of allelic variants and genotypes of the IL-17A and MMP-1 genes. The AA/AG genotypes of the IL-17A gene were associated with an increased risk of severe disease compared to the GG genotype in workers in the main group (OR=6.1; 95% CI 1.33-28.5; p=0.021) and in the control group (OR=7.26; 95% CI 1.34-39.25; p=0.016). Carriers of the A allele in the control group increased the risk of severe chronic periodontitis by 2.4 times compared to carriers of the G allele (OR=2.41; 95% CI 1.19-4.87; p=0.014). During the dental examination of employees of the ethylene oxide plant, the clinical course of periodontal diseases was more severe in comparison with the control group, and the number of patients with severe periodontitis was twice as high. It was found that the AA/AG genotypes of the IL-17A gene and the carrier of the A allele are associated with increased susceptibility to the development of severe chronic periodontitis. The association between the MMP-1 gene polymorphism and the risk of severe forms of chronic periodontitis has not been established. A risk factor for the development of inflammatory periodontal diseases in employees of the petrochemical complex is a complex of harmful production factors.

Objectives: To investigate the psychometric properties of the reflux symptom index (RSI) as short screening approach for the diagnostic of laryngopharyngeal reflux (LPR) in patients with confirmed diagnosed regarding the 24-hour multichannel intraluminal impedance-pH monitoring (MII-pH). Methods: From January 2017 to December 2018, 56 patients with LPR symptoms and 71 healthy individuals (control group) were prospectively enrolled. The LPR diagnosis was confirmed through MII-pH results. All subjects (n = 127) fulfilled RSI and the Reflux Finding Score (RFS) was performed through flexible fiberoptic endoscopy. The sensitivity and the specificity of RSI was assessed by ROC (Receiver Operating Characteristic) analysis. Results: A total of 15 LPR patients (26.8%) of the clinical group met MII-pH diagnostic criteria. Among subjects classified as positive for MII- pH diagnoses, RSI and RFS mean scores were respectively 20 (SD ± 10.5) and 7.1 (SD ± 2.5), values not significantly different compared to the negative MII-pH group. The metric analysis of the items led to the realization of a binary recoding of the score. Both versions had similar psychometric properties, α was 0.840 for RSI original version and 0.836 for RSI binary version. High and comparable area under curve (AUC) values indicate a good ability of both scales to discriminate between individuals with and without LPR pathology diagnosis. Based on balanced sensitivity and specificity, the optimal cut-off scores for LPR pathology were ≥ 5 for RSI binary version and ≥ 15 for RSI original version. Both version overestimated LPR prevalence. The original version had more sensitivity and the RSI Binary version had more specificity. Conclusions: It would be necessary to think about modifying the original RSI in order to improve its sensitivity and specificity (RSI binary version, adding or changing some items), or to introduce new scores in order to better frame the probably affected of LPR patient.

Tic disorders (TD) are childhood-onset neurological disorders. Immune system dysregulation has been postulated to play a role in TD, and its mechanisms likely involve dysfunctional neural-immune cross-talk, which ultimately leads to altered maturation of the brain pathways that control different TD clinical manifestations and behavioral and emotional damages. Clinical studies have demonstrated an association between TD and allergies and overactive immune responses at a systemic level. In this study, the Yale Global Tic Severity Scale was taken as a global measure of tic severity. Compared with the control group, the group of children with TD plus allergic diseases displayed significantly increased Yale total scores (p<0.05), which suggests that children with TD plus allergic diseases have heavier tic symptoms. Both motor and vocal tic scores are higher in the group of children with TD plus allergy compared with the control group. We counted immune cell subpopulations using FACS. T lymphocyte subset comparison of CD3, CD4, CD8, and CD4:CD8 expression ratios revealed that the level of CD3, CD4, and CD4:CD8 in children with TD plus allergic diseases was significantly lower than those of children with TD without allergic diseases. These differences were statistically significant (p<0.05) and suggest that children with TD plus allergic diseases have imbalanced T lymphocyte subsets. We concluded that allergy increased the severity of TD through an imbalance in cellular immunity. Studies need to be done to show whether treatment of allergic symptoms leads to a decrease in TD manifestations.

Sports activities cause increased loads in elite athletes’ joints. Current scientific knowledge highlights the importance of applied mechanical loads on the physiology and pathophysiology of the articular cartilage. Thus, it is possible that sporting activity has a role in the development of osteoarthritis (OA), a painful and damaging joint disease. The aim of the present study was to investigate and record osteoarthritic alterations in the ankle and foot complex in former Greek soccer players and also compare them with those in the general population. The study sample consisted of 170 male, former elite soccer players, aged between 42 and 55 years (mean = 49.8 years, standard deviation [SD] = 7.4). A control group of 132 men, aged between 42 and 55 years (mean, 50.7 years, SD = 9.9), with no regular athletic activity were examined. The development of osteoarthritic alterations was recorded through a questionnaire and clinical and radiological examination. Radiographic analysis of the images in former athletes group showed not only more signs of cartilage degeneration in comparison with the control group (P < .05) but also similar clinical manifestations (pain and impaired mobility; P > .05). Osteophyte formation is a frequent disease among former soccer players—with variations on radiographic images—but it does not appear in their clinical picture. However, it is likely that both spurs and subchondral sclerosis (main findings) are preclinical manifestations of OA. Levels of Evidence: Prognostic, Level II

Our objective for this study was to discuss the usability of mean platelet volume, which is associated with numerous vascular pathologies, in the early diagnosis of acute mesenteric ischemia. Acute mesenteric ischemia is an uncommon, life-threatening clinical condition mostly seen in the elderly. Early diagnosis of acute mesenteric ischemia and correction of blood circulation before necrosis occurs are important factors affecting prognosis. A total of 95 patients who underwent emergency surgery for acute mesenteric ischemia and 90 healthy volunteers as control group were included in this study. Age, gender, hemoglobin values, white blood cell counts, mean platelet volume, and platelet counts are recorded for evaluation. The mean platelet volume values were significantly higher in patients with acute mesenteric ischemia than in the controls (9.4 ± 1.1 fL and 7.4 ± 1.4 fL, respectively; P &lt; 0.001). Receiver-operating characteristic analysis demonstrated a cutoff value of mean platelet volume as 8.1 fL (area under the curve, 0.862), a sensitivity of 83.2%, and a specificity of 80%. As a result, in the patients who are admitted to the hospital with acute nonspecific abdominal pain and suspected of having acute mesenteric ischemia, high mean platelet volume values in routine hemograms support the diagnosis of acute mesenteric ischemia.

High Sensitivity Troponin T

High-sensitivity troponin T (hsTnT) helps in identifying pulmonary embolism patients at low risk of an adverse outcome. In 682 normotensive pulmonary embolism patients we investigate whether an optimised hsTnT cut-off value and adjustment for age improve the identification of patients at elevated risk.Overall, 25 (3.7%) patients had an adverse 30-day outcome. The established hsTnT cut-off value of 14 pg·mL−1 retained its high prognostic value (OR (95% CI) 16.64 (2.24–123.74); p=0.006) compared with the cut-off value of 33 pg·mL−1 calculated by receiver operating characteristic analysis (7.14 (2.64–19.26); p<0.001). In elderly (aged ≥75 years) patients, an age-optimised hsTnT cut-off value of 45 pg·mL−1 but not the established cut-off value of 14 pg·mL−1 predicted an adverse outcome. An age-adjusted hsTnT cut-off value (≥14 pg·mL−1 for patients aged <75 years and ≥45 pg·mL−1 for patients aged ≥75 years) provided additive and independent prognostic information on top of the simplified pulmonary embolism severity index (sPESI) and echocardiography (OR 4.56 (1.30–16.01); p=0.018, C-index=0.77). A three-step approach based on the sPESI, hsTnT and echocardiography identified 16.6% of all patients as being at higher risk (12.4% adverse outcome).Risk assessment of normotensive pulmonary embolism patients was improved by the introduction of an age-adjusted hsTnT cut-off value. A three-step approach helped identify patients at higher risk of an adverse outcome who might benefit from advanced therapy.

Background:Fibromyalgia (FM) is a common rheumatic disease characterized by chronic widespread pain, sleep and mood disorders. A higher prevalence of FM in women compared with men is well known, although the specific differences in clinical manifestations related to gender are still poorly defined. Brain-Derived Neurotrophic Factor (BDNF) is an endogenous growth factor that gained attention for its potential as biomarker of several diseases, including FM and depression.Objectives:The aims of this study were to investigate gender-related difference among males and females affected by FM in clinical manifestations, depressive features and BDNF serum level, evaluating also the diagnostic potential of the latter.Methods:We consecutively enrolled adult patients affected by FM (ACR 2016) referring to our out-patient clinic. Each subject underwent clinical and answered to questionnaires for the severity of FM symptoms (Revised Fibromyalgia Impact Questionnaire, R-FIQ) and depressive symptoms (Beck Depression Inventory-II, BDI-II). We collected blood samples from a subgroup of patients of both sexes, matched for age, for BDNF serum level dosage through ELISA. BDNF levels were assessed also in a control group, matched for sex and age.Results:The cohort was composed by 201 FM patients (172 F, 29 M), mean age 49.13. Females showed higher values of R-FIQ total score (p=0,0005) as well the specific items of the R-FIQ for pain (p=0,013), fatigue (p=0,014), memory problems (p=0,007), tenderness to touch (p<0,0001), balance problems (p<0,0001) and sensitivity to environmental stimuli (p=0,012) when compared with males (fig. 1). There was no difference in BDI-II between males and females, but notably male patients reported a significantly higher frequency of coexisting depressive disorder (p=0,038) (fig. 2). Serum BDNF levels were evaluated in 40 FM patients and 40 healthy controls (HC) (F:M 1:1). BDNF levels were significantly lower in FM patients compared with HC (p<0,0001). Among FM patients, BDNF levels were lower in males compared with females (p<0,0001) (fig.3). BDNF did not correlate with any clinical and clinimetric parameter. BDNF showed a good diagnostic performance (AUC=0,89, CI95%=0,82-0,9630, p<0,0001) (fig. 4). At a cut-off value <6,47 ng/dl, BDNF showed a specificity of 75% and a sensibility of 92,31%,(CI 95%=79,68-97.35) for FM identification (LR=3,692).Conclusion:FM clinical manifestations are strongly dependant from gender. While females present a more severe disease and a higher burden of symptoms, mood disorders tend to be a major characteristic of males with FM. Reduced BDNF serum levels have been reported as typical of depressive disorders. Our findings of lower BDNF levels in male FM patients compared to females support this hypothesis. BDNF have potential as biomarker of the disease and should be validated in larger cohorts.References:[1]Sarzi-Puttini et al. Nature Reviews 2020[2]Colucci-D’Amato et al.

Pharmacological Potential

The purpose of the study is to improve rehabilitation treatment of patients with chronic pancreatitis (CP) at inpatient stage by strengthening pharmacological potential of drug therapy due to inclusion of therapeutic physical factors (TPF) in therapeutic programs. Materials and methods. 159 patients with acute CP were observed. By simple randomization, 4 groups were formed: the control group (MG, 39 people) received standard drug therapy; 1st comparison group (GC1; 38 people) additionally received TPF; GC2 (40 people) in addition to treatment in GC1 had drinking mineral water «Slavyanovskaya»; in main group (42 people) in addition to the treatment in GC2 got preformed peloidotherapy on the cervical-collar zone. All the patients underwent the evaluation of clinical score and quality of life before and after medical rehabilitation. Results. In MG, clinical symptomatology leveling was by 78,2% (p<0,01), in GC1 — by 71,5% (p<0,01), GC2 — by 62,3% (p<0,01), CG — by 57,2% (p<0,01) on average immediately after the treatment, which was in a clear correlation with indicators of quality of life. In the long term (in 6 and 12 months), the advantage of combination therapy was noted with the same validity, the preservation of the achieved positive result was mostly noted in the MG: after 6 months the improvement in physical health compared to the initial values was noted by 34,4% (p<0,01), after 12 months — by 24,0% (p<0,05); mental — by 32,3% (p<0,01) and 22,5% (p<0,05), respectively. In both comparison groups, positive dynamics was 10–12% lower, and in the control group, after 6 months, there was only a tendency to improve quality of life indicators. Conclusion. The inclusion of TPF in the programs of the inpatient stage of medical rehabilitation of patients with chronic pancreatitis by strengthening the pharmacological potential of drug therapy contributes to the leveling of clinical manifestations (abdominal pain, dyspepsia and diarrhea), the result of which is an improvement in the quality of life of this category of patients.

Relevance. The paper demonstrates the need to implement modern diagnostic techniques for diagnosis of precancerous and cancerous lesions at early or preclinical stages. Additional diagnostic methods are necessary, e.g. tissue autofluorescence, which allows revealing insidious pathological risk zones, particularly precancerous and cancerous lesions, to evaluate the condition of the oral tissues in patients with chronic oral mucosa disorders, especially caused by trauma. Purpose – to assess trauma-specific effectiveness of autofluorescence spectroscopy (AFS) in risk group patients with chronic trauma of the oral mucosa to reveal early malignization signs.Materials and methods. 25 subjects were selected for the study and divided into 2 groups: main group – 20 patients with different manifestations of chronic oral mucosa trauma; control group – 5 subjects without visible clinical manifestations and without oral trauma factors. Autofluorescence spectroscopy was performed in both groups using AFS-400 stomatoscope.Results. The received data demonstrated that the change in autofluorescence doesn’t allow drawing final conclusions on the presence or absence of chronic oral trauma malignization signs.Conclusion. AFS-400 stomatoscope may be effective in differentiating between healthy and damaged tissues, but there is no solid evidence that the change in fluorescence shade can help differentiate between various types of damaged tissues. Autofluorescence spectroscopy should be considered as an additional method for examination of patients with chronic oral mucosa trauma to reveal early malignization signs.

The coronavirus disease COVID-19 is characterized by high mortality and the lack of effective etiotropic therapy. Activation of oxidative stress may be one of the links in the pathogenesis of organ damage of this infection. Objective. To assess the ability of Mexidol® to influence the rate of clinical improvement in pneumonia caused by the SARSCoV-2 virus in hospitalized patients with the novel coronavirus disease COVID-19 and concomitant discirculatory encephalopathy. 62 patients over the age of 18 years with confirmed new coronavirus disease COVID-19 according to computed tomography (CT) of the lungs (stages CT1, CT2, CT3) and PCR of a swab from the nasopharynx and oropharynx for SARS-CoV-2 virus RNA were included. After randomization patients of group 1 received an infusion of Mexidol® at a dose of 1000 mg/day, patients of group 2 – an infusion of isotonic sodium chloride solution for 7 days. Compared with the control group, the patients receiving Mexidol® therapy showed a significantly more pronounced decrease in body temperature, a tendency towards a decrease in the severity of shortness of breath. In the Mexidol® group, the concentration of superoxidedismutase did not change, while in the control group there was a tendency to its decrease, C-reactive protein decreased 2.2 times more than in the control group (p = 0.09). There was a tendency for a more rapid decrease in ferritin in the active intervention group. Mexidol® therapy can have a positive effect on the clinical manifestations and severity of laboratory-inflammatory syndrome in patients with the new coronavirus disease COVID-19. Key words: coronavirus disease COVID-19, oxidative stress, Mexidol
