INTRODUCTION. Among systemic vasopathies in children, IgA vasculitis Henoch Schoenlein (HS) is the most common, according to various authors, kidney damage is noted in 25-80 % and usually determines the prognosis of the disease.THE AIM of the study was to analyze clinical, laboratory, immunological, morphological characteristics, features of the course and treatment of nephritis associated with IgA vasculitis HS in children, as well as factors affecting the prognosis.PATIENTS AND METHODS. The study included 31 patients with morphologically verified nephritis due to IgA vasculitis HS (18 – boys, 13 – girls) aged 3 to 17 years, who were monitored at the Nephrology Department of the "2nd Children's City Clinical Hospital" of the National Center for Pediatric Nephrology and Renal Replacement therapy in Minsk from 2010 to 2019 yrs.The following parameters were analyzed: the clinical variant of kidney damage, laboratory tests (including the study of BAFF, RANTES lymphocyte activation molecules, pro-inflammatory IL1β, caspase1, TNFα, growth factors VEGF, TGF), 24 hours monitoring and office blood pressure measurements, ECHO cardiography with indicescalculation, ultrasound of the carotid arteries with the thickness of intima-media complex, morphological changes in the renal tissue, as well as treatment regimens.RESULTS. The contribution of deGal-IgA1, markers of T and B lymphocytes activation, pro-inflammatory and profibrotic molecules in the development of the disease is shown. Arterial hypertension was registered in 42 % of children, signs of heart remodeling according to the calculated indices in 19,3 %. Decrease level of adiponectin, vitamin D, leptin, increase concentration of obestatin, Pro-BNP, hs-CRP, and TSAT indicator classify patients with nephritis due to IgA vasculitis HS at moderate risk for the developmentof cardio-vascular disorders, which suggests the need for timely correction.CONCLUSION. In most cases, nephritis with IgA vasculitis HS has a benign course with rare relapses and progression to the end stage of chronic kidney disease (6,5 %).

The COVID-19 pandemic has highlighted the need for improved airborne infectious disease monitoring capability. A key challenge is to develop a technology that captures pathogens for identification from ambient air. While pathogenic species vary significantly in size and shape, for effective airborne pathogen detection the target species must be selectively captured from aerosolized droplets. Captured pathogens must then be separated from the remaining aerosolized droplet content and characterized in real-time. While improvements have been made with clinical laboratory automated sorting in culture media based on morphological characteristics of cells, this application has not extended to aerosol samples containing bacteria, viruses, spores, or prions. This manuscript presents a strategy and a model for the development of an airborne pandemic early warning system using aerosol sampling.

Due to the absence of the pathognomonic diagnostic criteria and to the diversity of clinical, serological and morphological manifestations, the diagnostic of the autoimmune hepatitis (AIH) remains to be a difficult task, which might lead to the delay of the timely beginning of the immunosuppressive therapy (IST), which in turn affects the disease outcomes. Aim.To studying the clinical, biochemical, immunological and morphological markers in patients with seronegative (SN) and seropositive (SP) AIH and the qualities of their response to the IST. Materials and methods.This retrospective cohort study included 82 AIH patients over the course of the years 20142019. All patients were selected in accordance with the criteria of the simplified assessment system of the IAIHG. Clinical, laboratorial and morphological characteristics of the AIH were analyzed. Therapy response was evaluated by the level of the ALT and IgG in 612 months after the start of the IST. The study material underwent statistical analysis using methods of parametrical and nonparametrical analysis. Statistical analysis was performed in the Statistica 13.3 (developed by StatSoft Inc., USA). Results.67/82 (81.70%) of the patients studied were women, median age of 54 years old [38; 70]. Patients with the diagnosis of the possible AIH according to the IAIHG made 85.4% (70 people). Almost everyone 96% (79/82) had morphological features of the interface-hepatitis with the lymphocytic/plasmocytic infiltration; emperipolesis was discovered in 63% of patients (49/82), hepatocellular rosette in 23% (19/82). Patients with SN AIH comprised 36.5% (30/82), with SP 63.4% (52/82). Comparative analysis demonstrated that the clinical profile in patients with SN and SP AIH is the same, while the incidence of immuno-associated diseases is significantly higher in the group of seronegative AIH. The morphological profile in the two AIH groups is identical in both typical and atypical manifestations. The number of responders to IST was 63% (19/30) SN AIH vs 67% SP AIH (35/52), did not differ significantly (p=0.529).However, that the number of patients with liver cirrhosis in the SN AIH group was twice as big as the ones with SP: 37% vs 17% (p=0.089). Conclusions.A comparative analysis of clinical, laboratory, morphological and clinical manifestations in the SN and SP AIH groups did not detected statistically significant significant differences, which may indicate that SN and SP AIH are the faces of one disease. It is possible that AB cannot be identified within the known spectrum of antibodies, or antibodies have slow expression, or are suppressed by the immune system. In any case, suspicions of AIH, in the absence of antibodies, it is recommended that liver biopsy be performed for the timely diagnosis of AIH and IST. Сirrhosis was more often diagnosed in the group SN AIH, which may be due to a later diagnosis, and therefore to untimely IST. The found frequent association of SN AIH with other immune-associated diseases requires a carefully study of this problem. The variety of clinical manifestations of AIH requires further study, the identification of clinical phenotypes with certain feature. This can help in the future to timely identify potentially problematic patients and predict a response to IST.

Abstract Background Histological findings of kidney involvement have been rarely reported in pediatric patients with SARS-CoV-2 infection. Here, we describe clinical, laboratory, and histological findings of two pediatric cases with almost exclusive kidney involvement by SARS-CoV-2. Results A 10-year-old girl with IgA vasculitis nephritis underwent kidney biopsy, showing diffuse and segmental mesangial-proliferative glomerulonephritis, and steroid therapy was initiated. After the worsening of the clinical picture, including an atypical skin rash, she was diagnosed with SARS-CoV-2. The re-evaluation of initial biopsy showed cytoplasmatic blebs and virus-like particles in tubular cells at electron microscopy. Despite SARS-CoV-2 clearance and the intensification of immunosuppression, no improvement was observed. A second kidney biopsy showed a crescentic glomerulonephritis with sclerosis, while virus-like particles were no longer evident. The second patient was a 12-year-old girl with a 3-week history of weakness and weight loss. Rhinitis was reported the month before. No medications were being taken. Blood and urine analysis revealed elevated serum creatinine, hypouricemia, low molecular weight proteinuria, and glycosuria. A high SARS-CoV-2-IgG titre was detected. Kidney biopsy showed acute tubular-interstitial nephritis. Steroid therapy was started with a complete resolution of kidney involvement. Conclusion We can speculate that in both cases SARS-CoV-2 played a major role as inflammatory trigger of the kidney damage. Therefore, we suggest investigating the potential kidney damage by SARS-CoV-2 in children. Moreover, SARS-CoV-2 can be included among infectious agents responsible for pediatric acute tubular interstitial nephritis.

BACKGROUND. In the modern era, COVID-19 is the biggest problem facing doctors and scientists around the world. SARSCоV-2 is a multisystem infection that is not limited to lung damage and has the immuno-mediated effect of negative effects on organs and systems, including the kidneys. To date, there is no precise understanding of the pathogenesis of nephrological disorders in patients with COVID-19. Patients with chronic kidney disease (CKD) are a group of particularly high risk of CO-VID-19 infection and high mortality in the development of the disease.THE AIM: to evaluate the features of the course of a new coronavirus infection (COVID 19) in patients with acute kidney injury and terminal renal insufficiency.PATIENTS AND METHODS. The study of clinical, laboratory and instrumental parameters was carried out in 119 patients (67 men and 52 women) diagnosed with COVID-19. The average age of the patients was 63.1±1.7 years. All patients were divided into two groups: group 1 - patients with CKD and HD, group 2 - patients with newly diagnosed kidney damage against the background of coronavirus infection (COVID-19). Statistical data analysis was carried out using the software package "IBM SPSS Statistics 21.0" (USA) (Russified version).RESULTS. As a result of the study, it was found that in the clinical picture of COVID-19 patients suffering from CKD and undergoing hemodialysis, such a symptom as myalgia was noted 2 times more often, the percentage of saturation of arterial blood hemoglobin with oxygen (SaO2,%) was significantly lower compared to patients with newly diagnosed kidney damage on the background of infection. The duration of the temperature reaction during the disease was 5 times longer than in patients without CKD. Although the incidence of lung damage in patients of both groups was identical, mortality was significantly higher in the group of patients with CKD.CONCLUSION. In the patients examined by us, proteinuria, an increase in the level of nitrogenous metabolites, as well as D-dimers in both groups, are associated with increased mortality. Mortality in patients with CKD and HD was several times higher than in those without pathology of the urinary system. The severity of the patients' condition was primarily due to the symptoms of damage to the respiratory system, but the degree of renal dysfunction is undoubtedly an important prognostic value. Thus, monitoring the state of individual nephron structures in patients with CO-VID-19 is of great importance, and emergency nephroprotective measures may be crucial in the fight against cytokine storm.

Hypophysitis, secondary to programmed cell death 1 protein (PD1) and programmed cell death 1 ligand 1 (PDL1) inhibitors, were thought to be rare, with only a few studies describing more than one case with long-term follow-up. The aim of the present study was to describe the clinical, laboratory, and morphological characteristics of PD1/PDL1 inhibitor-induced hypophysitis, and its long-term course. This cohort study was conducted at the University Hospital of Lyon, France, with longitudinal follow-up of patients. Seventeen cases of PD1/PDL1 inhibitor-induced hypophysitis were included. The median time to onset of hypophysitis was 28 weeks (range: 10–46). At diagnosis, 16 patients complained of fatigue, 12 of nausea or loss of appetite, while headache was rare. We found no imaging pituitary abnormality. All patients presented adrenocorticotropic hormone (ACTH) deficiency; other pituitary deficiencies were less common (n = 7). At last follow-up (median: 13 months), ACTH deficiency persisted in all but one patient and one patient recovered from gonadotropic deficiency. PD1/PDL1 inhibitor-induced hypophysitis is a clinical entity different from those associated to cytotoxic T-lymphocyte antigen-4 (CTLA4) inhibitors, with less obvious clinical and radiological signs, and probably a different mechanism. The paucity of symptoms demonstrates the need for systematic hormonal follow-up for patients receiving PD1/PDL1 inhibitors.

Purpose of the study. The role of interventional methods of the treatment of acute infected necrotic pancreatitis depending on the morphological characteristics of the disease was determined. Material and methods. In present prospective cohort study, we included 96 patients with acute infected necrotizing pancreatitis. All patients were stratified according to morphologic features. Stepup approach with following steps of interventions was applied: percutaneous drainage of infected fluid collections, increasing of drainages diameter and number of it and open or minimally invasive necrosectomy. Clinical, laboratory, and instrumental monitoring were the defining indicators for the stopping of the treatment or for the passing to the next step of the treatment. Results. At the first step 7 of 96 patients with superficial focal necrosis, a necrosis index of 2 points and a category D were successfully treated. Other 89 patients were passed to the second step of treatment, of which 23 patients with superficial subtotal necrosis, necrosis index of 2 points and category E were successfully treated. Another 66 patients had undergone a third step of treatment. A multivariate regression analysis was conducted that allowed to identify predictive factors of inefficiency of using of percutaneous drainage interventions (stages I and II) as a final stage of treatment: transmural subtotal or total necrotizing pancreatitis (OR = 1,58; 95% CI 1,03–3,88; p = 0,033); Necrosis index of 4 or more points (OR = 3.19, 95% CI 1.57–8.37; p = 0,003); heterogeneous peripancreatic fluid collection (OR = 4,15, 95% CI 1,49–5.19; p = 0,001); The CT-index of severity of acute pancreatitis of 7 or more points (OR = 1,89, 95% CI: 1,03–3,43; p = 0,029). Conclusion. Step-up approach showed following results: 7,3% patients were treated at the first step, 24% – at the second step. Third step of treatment was applied in 68,7% of patients, of witch 12,5% was treated with laparoscopic necrosectomy. Predictors of ineffectiveness of ultrasound guided percutaneous drainage as the final treatment method are: necrosis index of 4 or more, heterogeneous paripancreatic fluid collections, subtotal and transmural necrotizing pancreatitis. Keywords: infected pancreatic necrosis, stepup approach, percutaneous catheter drainage, uncontrolled infection, necrosectomy.

During the almost 50 years since Streptococcus mutans was first suggested as a factor in the etiology of dental caries, a multitude of studies have confirmed the cariogenic potential of this organism. Streptococci have been isolated from human and animal caries on numerous occasions and, with few exceptions, they are not typable by the Lancefield technique but are relatively homogeneous in their biochemical reactions. An analysis of the guanine-cytosine (G-C) composition of the DNA from strains K-1-R, NCTC 10449, and FA-1 by one of us (ALC) revealed significant differences and DNA-DNA reassociation experiments indicated that genetic heterogeneity existed among the three strains. The present electron microscopic study had as its objective the elucidation of any distinguishing morphological characteristics which might further characterize the respective strains.
