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.

Aim. The study of anamnestic and clinical-morphological features of the malignant ovarian tumors (MOT) course in children.Material and methods. Clinical and anamnestic features of 47 cases of MOT in children who received special treatment in the Department of pediatric oncology of the SI “Republican Oncological Scientific Center” for 2005- 2018 were compared. To identify clinical morphological features patients were divided into two groups according to histotypes “teratoblastoma” (17 patients) and “dysgerminoma” (25 patients). The study used anamnestic, physical, clinical-laboratory, sonography, morphological, statistical methods.Results and discussion. As a result of the study, it was found that the main complaints at admission were pain and palpable formation in the abdomen, which had dimensions of up to 10 cm in 19 (40.4%) cases, and in 28 (59.6%) cases - more than 10 cm. Ultrasound examination revealed a tumor-like formation of a heterogeneous/cystic structure, with dense walls, multiple chambers, with inclusions, tuberous, reaching significant sizes of 40-400 mm. The average values of the AFP onco-marker were 155 U/ml, Ca-125 - 87 U/ml, which exceeded the reference values. Dysgerminoma was found in more than half of cases - 25 (53.2%). There were no statistically significant differences in clinical and anamnestic measures between the different histological variants.Conclusion. Comparative analysis of peculiarities of the clinical-morphological course of MOT in children depending on histological type showed no statistically significant differences.

Aim.To generalize the results of existing research studies carried out to investigate autoimmune hepatitis (AIH) in children, and the contemporary approaches to the diagnosis and therapy of the disease. Key points. According to the results of serological studies, two types of AIH can be distinguished in children. AIH of type 1 is diagnosed, when anti-smooth muscle autoantibodies (ASMA) and/or antinuclear autoantibodies (ANA) have been detected. AIH of type 2 AIH is diagnosed, when liver kidney microsomal autoantibodies (anti-LKM-1) and/ or anti-liver cytosolic autoantibodies (anti-LC-1) have been detected. Liver parenchymal inflammation responds well to a standard immunosuppressive therapy with prednisolone and azathioprine. Disease relapses are observed in about 40% of patients during treatment. It is expedient to treat children at least for 2–3 years before attempting to cancel the treatment, which decision should be considered only when the levels of transaminases have remained normal and IgG has been negative, or autoantibody titers have been low (1:20 using immunofluorescence method) for at least a year. Before attempting to cancel the therapy, liver biopsy and histological study should be repeated in order to exclude the possibility of residual inflammatory changes. For a small number of patients, who do not respond to standard treatment and those who suffer from frequent disease relapses, it is advisable to offer an alternative immunosuppressive treatment, the effectiveness of which is still ambiguous and poorly understood (including, in order of priority, mycophenolate mofetil, calcineurin inhibitors, rituximab, Inhibitor of tumor necrosis factor-alpha). In cases of refractoriness to therapy and the disease progression to liver cirrhosis and its decompensation, liver transplantation is justified. It is shown that AIH might relapse after liver transplantation. De novo AIH develops after liver transplantation as a result of non-autoimmune diseases; it is characterized by the presence of autoantibodies (ANA, ASMA and typical or atypical anti-LKM-1), and histologically characterized by a pattern similar to that of AIH. De novo AIH after liver transplantation responds well to a classical immunosuppressive therapy, but not to a standard antiretroviral therapy. In the review, we discuss issues associated with the clinical manifestations and diagnosis of AIH in children. Approaches to the treatment and long-term observation of such children are reviewed, including, i.e., those formulated by the main group of the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) members.Conclusion. Autoimmune hepatitis (AIH) in children has a progressive course with the outcome to liver cirrhosis. The presented review has summarized approaches to the diagnosis and selection of AIH therapy in children.

This study analyzed the potential of producingMelissa officinalisL. using stem cuttings. Four different hormones (IAA, IBA, NAA, and GA3) were applied to the cuttings, with and without buds, in two doses (1000 mg/L and 5000 mg/L), and after 60 days, 10 morphological characteristics of newly generated plants were detected, and a statistical analysis was carried out. The results of the study show that the cuttings with at least one bud must be used in order to produceM. officinalisusing stem cuttings. Even though the auxin group hormones (IAA, IBA, and NAA) do not have an apparent effect on rooting percentage, these hormones were detected to affect the morphological characteristics of the newly generated plants, especially root generation. GA3 application has a considerable effect on stem height.

In COVID-19, a percentage of patients develop severe disease, with high mortality, since has been necessary to study its characteristics to stop the progression of the disease. A retrospective study was carried out in a cohort of 150 adult patients attended at Manuel Fajardo Hospital in Villa Clara, Cuba, from March to June 2020. Demographic, clinical, laboratory, gasometric and radiological variables measured at hospital admission were analyzed, defining two groups of patients according to clinical evolution: severe and non-severe. For the comparison of the groups a bivariate analysis was performed, with the objective of determining those variables with a significant association to severity. Of the total number of patients, 26 (17.3%) evolved to severity and 124 (83.7%) evolved satisfactorily. Severe patients were characterized by advanced age (mean: 83 years) and comorbidities; the most significant being hypertension, diabetes mellitus, heart disease, chronic kidney disease and cancer (p< 0.0001). Polypnea and diarrhea were the clinical manifestations with the highest association with severity (p<0.0001), followed by fever (p=0.0157). The quick SOFA prognostic scale proved to be a useful instrument to evaluate patients at admission. Laboratory variables: neutrophils, lymphocytes, neutrophil/lymphocyte ratio, hemoglobin and lactate dehydrogenase were the most associated with severity (p<0.0001). Leukocytes, lactate, D-dimer, C-reactive protein, glycemia and calcium also showed significant results (p<0.05). Of the gasometric variables, arterial oxygen pressure and saturation were the most significantly associated with severity; as well as the presence of pulmonary infiltrates or consolidation in the chest X-ray (p<0.0001). The study allowed us to identify variables at hospital admission associated with progression to severe forms of the disease.

Abstract The clinical and para clinical manifestations of influenza in various patients have range from an autoimmune disease to a life-threatening respiratory infection. In addition, the severity of the disease is influenced by factors such as demographic factors, underlying diseases, and immune response. Therefore, in this study, we evaluated the clinical, laboratory and epidemiological characteristics of patients with this type of influenza in Babol (north of Iran). This study was conducted as a descriptive cross-sectional study from October 2015 to March 2016. Subsequently, in this study, records of 123 patients with clinical signs of the influenza-like disease who have undergone the clinical sign in hospitals affiliated to Babol University of Medical Sciences were reviewed. Of 123 patients admitted to a possible diagnosis of influenza, 58 patients (47.2%) were PCR positive for H1N1, while seventy nine (64.2%) participants were women and 21 (17.1%) had diabetes or underlying lung disease. Most of the involved age groups were of individuals above the age of 50. These were followed by the 21-35 years-old. Fever (78%), cough (65.9%), shivering (58.5%) and myalgia (56.1%) were the most common clinical symptoms. Increased levels of transaminases (43.1%), leukocytosis (35.8%) and thrombocytopenia (34.2%) were as well reported in patients as the most frequently reported para clinical findings. In the present study, the most usual clinical symptoms were fever, cough, chill, and myalgia, while gastrointestinal symptoms were also noticeably observed in patients. In an experimental study, a significant number of patients showed leukocytosis and thrombocytopenia and increased transaminases.
