ABSTRACT
Aim: Although most patients with COVID-19 experience respiratory tract infections, severe reactions to the virus may cause coagulation abnormalities that mimic other systemic coagulopathies associated with severe infections, such as disseminated intravascular coagulation and thrombotic microangiopathy. Fluctuations in platelet markers, which are an indicator of the acute phase response for COVID-19, are of clinical importance. The aim of this study is to evaluate the relationship between disease severity and Platelet Mass Index (MPI) parameters in COVID-19 patients. Material(s) and Method(s): This retrospective observational study was conducted with patients who were diagnosed with COVID-19 in a tertiary hospital. The study was continued with the remaining 280 patients. All laboratory data were scanned retrospectively from patient files and hospital information system. Result(s): A very high positive correlation was found between PMI and PLT. The PMI value in women was significantly higher than in men. It was observed that PMI did not differ significantly in terms of mortality, intubation, CPAP and comorbidity. PMI vs. Pneumonia Ct Severity Score, biochemistry parameters (AST, CRP), hemogram parameters (WBC, HGB, HCT, MCV, LYM, MPV EO) and coagulation factors (aPTT and FIB) at various levels of positive/negative, weak and strong, and significant relationship was found. There was no significant relationship between hormone and D-dimer when compared with PMI. Discussion(s): Although platelet count alone does not provide information about the prognosis of the disease, PMI may guide the clinician as an indicator of lung damage in seriously ill patients.Copyright © 2022, Derman Medical Publishing.

ABSTRACT
Objectives: Varicella is common infectious disease mainly in childhood, usually is a mild, self-limited illness and complications are usually rare. The incubation period for this disease is generally 14- 16 days but may vary from 7 to 21 days. Varicella in the adults with comorbidities or immunosuppressed children may be severe and prolonged with complications. Method(s): A case report of a 6-year-old girl hospitalized for new-onset manifestations of disseminated vesicular exanthema, the manifestations of which occurred mainly on the chest, back, capillitium, oral cavity, and genital area. The child was suffering from abdominal, knee and lumbosacral pain at that time. The patient's history revealed that 10 days prior to the cutaneous manifestations, she had influenza with bronchopneumonia requiring oxygen therapy, steroids and antibiotics. Result(s): The condition progressed within 48 h, complicated by the development of multi-organ failure, coagulopathy with the development of disseminated intravascular coagulopathy over the course of antiviral, antibiotic and antifungal therapy. Laboratory parameters included high elevation of C-reactive protein, il-6, leukocytosis, neutrophilia and highly elevated liver enzymes. Varicella infection was confirmed by detection of herpes zoster virus - polymerase chain reaction (PCR) from vesicles. The patient received intravenous immunoglobulin therapy at a dose of 2 g/L and fresh frozen plasma, thrombocyte concentrate. The girl was intubated with analogization. Laboratory parameters subsequently revealed high anti CoV-2 positivity, high CoV-2 IgG positivity and negative CoV-2 IgM. The patient's condition did not preclude the course of multisystem inflammatory syndrome in children (MIS-C) corticosteroids were added to the treatment at a dose of 1 mg/kg weight. Patient's condition stabilized after 1 month. Discussion(s): Our case report presents an example of fulminant complicated life-threatening course of varicella. Even in common respiratory infections, we must think about the risk and consequences of coinfections and post-infectious complications such as in our case especially influenza and COVID-19.
ABSTRACT
The cavernous sinus is one of the dural venous sinuses which plays an important role in venous outflow from the brain and eye sockets and in the regulation of intracranial circulation. We report a case of septic cavernous sinus thrombosis in a female patient with COVID-19. The disease often results in alterations of blood rheology, thrombosis in different organs, and septic complications. This article aims to raise awareness of healthcare professionals about the characteristics of COVID-19 that might cause septic cavernous sinus thrombosis in patients with severe comorbidities. Laboratory testing revealed severe comorbidities, including diabetes mellitus and liver cirrhosis caused by hepatitis C. They manifested with an impaired protein production in the liver and coagulation disorders. Systemic effects of SARS-CoV-2 on the vascular endothelium aggravated preexisting coagulation disorders and led to hemorrhage into retrobulbar tissue and clinical signs of septic cavernous sinus thrombosis, including swelling of the eyelids, bilateral exophthalmos, and ophthalmoplegia, followed by necrosis of the facial skin.Copyright © 2022, Dynasty Publishing House.

ABSTRACT
Problem: Several large studies have demonstrated that COVID-19 pregnant individuals are at a significant risk for severe disease and adverse pregnancy outcomes. The mechanisms underlying these phenomena remain to be elucidated and are the focus of our project. Although fetal and placental infection is rare, placental abnormalities and adverse pregnancy outcomes associated with placental dysfunction in COVID-19 cases have been widely reported. In particular, placental thrombosis and lesions consistent with maternal vascular malperfusion (MVM) of the placenta are common in individuals with COVID-19. Since thrombotic complications have been associated with COVID-19, it is not surprising that pregnant individuals with COVID- 19 are at risk for placental thrombosis. Method of Study: Placentas were evaluated histologically. Extracellular vesicles were isolated by serial centrifugation. Result(s): Adverse pregnancy outcomes associated with these placental lesions, including hypertensive disorders of pregnancy (gestational hypertension and preeclampsia), small for gestational age (SGA, birthweight < 10th percentile for gestational age), and preterm birth (PTB, < 37 weeks) are significantly increased among pregnant individuals with COVID-19. Placental infection with SARSCoV- 2 is uncommon, but multiple inflammatory and metabolic factors are likely to affect the placenta, including circulating extracellular vesicles (EVs) derived from various organs that have been associated with COVID-19 pathology and disease severity.We have analyzed over 500 placentas from COVID-19 pregnancies and found marked changes in placental morphology, characterized by abnormal maternal and fetal vessels, intervillous thrombi, and fibrin deposition, even in the face of mild or asymptomatic disease. We detected increased levels of small EVs in maternal serum from COVID-19 cases compared to controls and increased levels of mitochondrial DNA in EVs from COVID-19 cases. In in vitro experiments, we found increased oxidative stress in uterine endothelial cells and primary trophoblasts. Syncytialization of trophoblast cells following exposure to EVs from pregnant COVID-19 patients was markedly reduced. RNAseq of trophoblast cells exposed to EVs from pregnant COVID-19 patients revealed disruption of multiple pathways related to mitochondria function, oxidative stress, coagulation defects, and inflammation. Timing of infection during pregnancy (first, second, and third trimester) altered EV size distribution, cargo content, and functional consequences of trophoblast EV exposure. Conclusion(s): Our studies show that COVID-19 infection during pregnancy has profound effects on placenta morphology and function. It remains to be determined what the long-term consequences are on the offspring.
ABSTRACT
The literature review showed the main scenarios of SARS-CoV-2-associated myocardial injury. On the basis of the analysis of literature it can be concluded that myocardial lesion is multi-factor at COVID-19. Possible scenarios include direct damage to myocardium, development of acute systemic inflammatory response and cytokine storm, effects of acute respiratory distress syndrome, coagulopathy and electrolyte imbalance associated with COVID-19, as well as the toxic effects of drugs used in SARS-CoV-2 treatment schemes. At the same time, a rather vague concept - <<acute damage of myocardium>> - is often used to describe symptoms and laboratory changes in literature. Given the multifactor of myocardial lesions in COVID-19, the clinician often faces a difficult situation - the need for a nosological interpretation of the clinical status of the patient. Knowledge and correct verification of the leading pathogenetic variant of a heart injury can simplify this task, narrow the scope of diagnostic monitoring and organize a personalized approach to therapy.Copyright © 2022 Sinergia Press.

ABSTRACT
Objectives: It is well known that severe COVID-19 is associated with complex immunological and inflammatory dysregulation. Both these physiopathological events translate to a high risk of major thrombotic or hemorrhagic events. In patients treated with venovenous extracorporeal membrane oxygenation (VVECMO), membrane dysfunction might affect systemic oxygenation and limit its duration-expectancy. This study aimed to assess the possible causes of extracorporeal membrane failure in COVID-19 patients and its impact on outcome. Method(s): Retrospective, single-center, observational case-control study involving adult COVID-19 patients admitted to an ECMO referral centre in a tertiary university hospital. All patients required VVECMO for acute respiratory failure, including 48 cases who needed one or more extracorporeal membrane exchanges and 45 controls (no membrane exchange). These two groups were compared for demographic characteristics, severity of the disease using validated scores (SAPS II and SOFA), duration of ECMO run, coagulation assessment, cumulative anticoagulation dose, associated complications, and outcomes (ICU and hospital mortality). Result(s): Most patients were males (71.0%) and younger than 50 years (79.5%). Median ECMO run duration was significantly longer in the case group (35.0 vs 14.0 days, p <0.001), as well as ICU length-of-stay (45.5 vs 28 days, p <0.001). Membrane exchange tended to be associated with sepsis (56% vs 33%, p=0.037), major hemorrhage (58% vs 43%, p=0.022), heparin-induced thrombocytopenia (25% vs 9%, p=0.054), higher D-dimer title (17.36 ng/dL vs 7.5 ng/dL, p=0.07) and lower platelet counts (133.000/muL vs 154.000/muL). Median SAPS II (32.0 vs 33.0, p=0.20) and the mortality (27% vs 24%, p >0.99) were similar between these groups. Conclusion(s): In patients with SARS-CoV-2 pneumonia and severe hypoxemia treated with VVECMO support the emergence of infection, coagulopathy and inflammation were associated with high risk of membrane dysfunction. No impact on mortality could be confirmed from these data. Anticoagulation monitoring and dosing strategies should be reinforced to promote membrane protection.
ABSTRACT
The experience of managing patients with COVID-19 around the world has shown that, although respiratory symptoms predominate during the manifestation of infection, then many patients can develop serious damage to the cardiovascular system. However, coronary artery disease (CHD) remains the leading cause of death worldwide. The purpose of the review is to clarify the possible pathogenetic links between COVID-19 and acute coronary syndrome (ACS), taking into account which will help to optimize the management of patients with comorbid pathology. Among the body's responses to SARS-CoV-2 infection, which increase the likelihood of developing ACS, the role of systemic inflammation, the quintessence of which is a "cytokine storm" that can destabilize an atherosclerotic plaque is discussed. Coagulopathy, typical for patients with Covid-19, is based on immunothrombosis, caused by a complex interaction between neutrophilic extracellular traps and von Willebrandt factor in conditions of systemic inflammation. The implementation of a modern strategy for managing patients with ACS, focused on the priority of percutaneous interventions (PCI), during a pandemic is experiencing great difficulties due to the formation of time delays before the start of invasive procedures due to the epidemiological situation. Despite this, the current European, American and Russian recommendations for the management of infected patients with ACS confirm the inviolability of the position of PCI as the first choice for treating patients with ACS and the undesirability of replacing invasive treatment with thrombolysis.Copyright © 2023 Stolichnaya Izdatelskaya Kompaniya.

ABSTRACT
Langerhans cell histiocytosis (LCH) is an abnormal clonal proliferation of Langerhans cells. The prognosis varies depending on the form of the disease and organ damage. Any organs and systems can be involved in the pathological process in various combinations. A poor response to standard therapy and an unfavorable prognosis are characteristic of patients with a multisystem form of LCH and involvement of organs at risk. Skin lesions are a classic sign of LCH. Purpose - to describe the complexity and duration of diagnosis of LCH with multisystem damage in a boy aged 2 years and 2 months, infected with poliomyelitis and coronavirus. Clinical case. The first clinical manifestations of LCH in the child debuted with an eczematous-seborrheic rash on the scalp with spread to the limbs and trunk. The child was treated for toxicoderma, hemorrhagic vasculitis at the place of residence for 6 months. The boy lost 1.5 kg of body weight in 1 month. At the time of hospitalization, seborrheic-eczematous rashes on the skin with a hemorrhagic component, trophic-inflammatory changes in the nails of the hands, signs of protein-energy deficiency, stomatitis, gingivitis, hepatosplenomegaly, polyserositis, diabetes insipidus, osteolytic foci of the frontal bones were found. Results of the tests: anemia, thrombocytopenia, hypoproteinemia and hypoalbuminemia, coagulation disorders. The patient had the onset of lower flaccid paraparesis, muscle hypotonia. The boy was diagnosed with a number of infectious complications, including poliomyelitis (a derivative of vaccine poliovirus type 2), COVID-19. The child received LCH-III cytostatic therapy with a positive effect. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies.Copyright © 2023 Institute of Physics of the Russian Academy of Sciences. All rights reserved.
ABSTRACT
Objectives: To describe our experience in ECMO for acute myocarditis Methods: Descriptive, retrospective study (2018-2022) of a cohort of 8 patients < 16 years with acute myocarditis who were assisted on ECMO. Result(s): 8 patients were collected, (6 females), with a mean age 7;8 years [range 0;1-13;8]. In 7/8, the reason for cannulation was hemodynamic instability refractory to medical treatment, with a mean inotropic score of 70 [range 10-122]. Sixty-two percent presented cardiorespiratory arrest prior to cannulation and 2 of them needed ECRP. The mean precannulation troponin level was 1498 ng/ml [range 89-6212]. Primary transport was performed in 4 patients. ECMO was peripheral veno-arterial in 100%, jugulo-carotid in 2/8 and femoro-femoral in 6/8. All patients underwent atrioseptostomy. They received treatment with levosimendan, immunoglobulins, corticoids and carnitine. In 4 acute infectious etiology was confirmed (parvovirus, influenza and SARSCoV2), another one was due to PIMS-TS and in 3 no etiology was found. Six patients underwent myocardial biopsy and 5 of them showed inflammatory infiltrates. The mean time on ECMO was 8 days [range 3-14], 2 of them requiring 2 ECMO courses. The mean length of PICU stay was 21 days [range 10-50]. Two were transferred to a heart transplant center. The main complications were arterial hypertension (88%), bleeding (63%), neurological (50%), arrhythmias (38%), coagulopathy (38%) and infectious (38%). One patient required renal replacement therapy. 1 patient died, 2 had moderate neurological sequels. Conclusion(s): ECMO is a therapeutic option in patients with fulminant myocarditis refractory to medical treatment and may help improve their prognosis.
ABSTRACT
Objective: Hypercoagulation and high incidence of thrombosis during COVID-19 is well established. However, there is a lack of data, how it changes over time. The main purpose of our study was to access different parts of hemostasis in few months after acute disease. Material and methods. Patients discharged from our hospital were invited for follow up examination in 2,3-3,8 (group 1 - 55 pts) or 4,6-5,7 months (group 2 - 45 pts) after admission. Control group (37 healthy adults) had been collected before pandemic started. Standard coagulation tests, aggregometry, thrombodynamics and fibrinolysis results were compared between groups. Result(s): D-dimer was significantly higher, and was APPT was significantly lower in group 2 compared to group 1, while fibrinogen, prothrombin levels didn't differ. Platelet aggregation induced by ASA, ADP, TRAP, spontaneous aggregation didn't differ significantly between groups. Thrombodynamics revealed hypocoagulation in both group 1 and group 2 compared to control: V, mum/min 27,3 (Interquartile range (IQR) 26,3;29,4) and 28,3 (IQR 26,5;30,1) vs. 32,6 (IQR 30,4;35,9) respectively;all p < 0,001. Clot size and density in both group 1 and group 2 were significantly lower than in control group. Fibrinolysis appeared to be enhanced in x2 compared to control and group 1. Lysis progression, %/min was higher: 3,5 (2,5;4,8) vs. 2,4 (1,6;3,5) and 2,6 (2,2;3,4) respectively, all p < 0,05. Lysis onset time in both group 1 and group 2 was significantly shorter compared to control. Conclusion(s): We revealed normalization of parameters of clot formation process in 2-6 months after COVID-19, while fibrinolysis remained still enhanced. Further study is required to investigate the clinical significance of these changes.Copyright © Creative Cardiology 2021.
ABSTRACT
Up to 70% of patients hospitalized for COVID-19 need respiratory support, up to 10% need high-flow oxygen therapy, non-invasive and invasive ventilation. However, standard methods of respiratory support are ineffective in 0.4-0.5% of patients. In case of potentially reversible critical refractory respiratory failure that patients may require ECMO. Management of patients with extremely severe COVID-19 associates with numerous clinical challenges, including critical illness, multiple organ dysfunction, blood coagulation disorders, requiring prolonged ICU stay and care, use of multiple pharmacotherapies including immunosuppressive drugs. Pharmacological suppression of immunity is associated with a significant increase in the risk of secondary bacterial and fungal infections. Currently, data on epidemiology of secondary infections in patients with COVID-19 undergoing ECMO is limited. Aim. To study the prevalence and etiology of secondary infections associated with positive blood cultures in patients with extremely severe COVID-19 requiring ECMO. Materials and methods. A single-center retrospective non-interventional epidemiological study including 125 patients with extremely severe COVID-19 treated with ECMO in April 2020 to December 2021. Results. Out of 700 blood culture tests performed in 125 patients during the study, 250 tests were positive confirming bacteremia/fungemia. Isolated pathogens varied depending on the duration of ECMO: gram-positive bacteria (primarily coagulase-negative staphylococci) dominated from the initiation of ECMO support;increased duration of ECMO associated with an increasing the proportion of pathogens common in ICU (Klebsiella pneumoniae and/or Acinetobacter baumannii with extensively drug resistant and pan-drug resistant phenotypes, and vancomycin-resistant Enterococcus faecium). When ECMO lasted more than 7-14 days, opportunistic pathogens (Candida species, Stenotrophomonas maltophilia, Providencia stuartii, non-diphtheria corynebacteria, Burkholderia species and others) prevailed as etiological agents. Conclusion. Longer duration of ECMO resulted in increasing the rates of infectious complications. In patients undergoing ECMO for more than 14 days, the microbiological landscape becomes extremely diverse, which hampers choosing an empirical antimicrobial therapy. Since potential pathogens causing secondary infections in patients during ECMO are difficult to predict, rapid identification of rare opportunistic pathogens and their sensitivity profile, followed by targeted administration of antimicrobials, seems most beneficial.Copyright © 2023, V.A.

ABSTRACT
Introduction: TBX1 haploinsufficiency is an inborn error of immunity with the phenotype of DiGeorge Syndrome. DiGeorge Syndrome has variable immunodeficiency associated with grade of thymic hypoplasia ranging from mild with no infections to severe requiring thymus implant. Enterovirus is an example of an opportunistic infection that can be fatal in these patients. Case Presentation: A 1 year old girl with TBX1 haploinsufficiency complicated by Tetralogy of Fallot, pulmonary atresia, high arched palate, and vesicovaginal fistula presented for elective cardiac repair surgery from another country due to failure to thrive and cyanosis. She had no prior infectious history but was on sulfamethoxazole-trimethoprim for prophylaxis. She was asymptomatic with a negative COVID test but no other infectious studies performed. Immediately postoperatively, she was febrile and nasal respiratory viral panel was positive for rhinovirus/enterovirus with increased procalcitonin and leukocytosis with left shift. She decompensated with multi-organ failure and cardiac arrest on postoperative day two. She was cannulated to veno-arterial extracorporeal membrane oxygenation (ECMO). Pre-operatively, she had a normal absolute lymphocyte count. No thymus tissue was observed in surgery. She had profound CD3 lymphopenia to 130 cells/cmm when critically ill. Enteroviral meningitis was suspected as no infectious, cardiac, or other pathology could be identified causing decompensation. Enteroviral serum polymerase chain reaction (PCR) test was negative while lumbar puncture deferred due to clinical status. She was treated with immunoglobulin. Offlabel investigational drug pocapavir was considered but deferred to patient's irreversible neurological status. The patient was disconnected from ECMO and expired. Discussion(s): Though we cannot confirm that this patient had enteroviral meningitis, invasive enteroviral infections are associated with elevated transaminases, coagulopathy, and seizures all present in our patient. There has also been reported negative serum enteroviral PCR but positive CSF enteroviral PCR in an immunodeficient patient. Additionally, this case highlights the importance of immunologic evaluation in patients with DiGeorge Syndrome and questions if asymptomatic viral screening for viruses like enterovirus should be considered pre-operatively in patients with inborn errors of immunity. This case highlights potential treatment options for invasive enteroviral infections in patients with inborn errors of immunity: high dose immunoglobulin, fluoxetine, and pocapavir.Copyright © 2023 Elsevier Inc.
ABSTRACT
Introduction: Children requiring venoarterial (VA) extracorporeal membrane oxygenation for long durations may have increased risk of complications compared to venovenous (VV) ECMO. The purpose of this study was to evaluate the feasibility and safety of conversion from VA to VV ECMO. Method(s): This is a retrospective review of all children requiring VA ECMO who underwent conversion to VV ECMO at a single institution, from 2015- 2022. Indications for and methods of conversion were examined as well as adverse events including re-operation, ischemic complications, renal failure, and mortality. Descriptive statistics were calculated. Result(s): Of 422 pediatric patients on initial VA ECMO, only three children (0.7%) underwent conversion from VA to VV support, ages 10-19: for hypoxic respiratory failure due to COVID19, for cardiac dysfunction following orthotopic heart transplant, and for sepsis with associated left ventricular dysfunction. The indications for conversion were bleeding from cannulation site (n=2, 66%) and an anticipated prolonged ECMO run (n=1, 33%). For all three patients, the method of conversion was cutdown with femoral arterial repair followed by placement of additional jugular venous cannulas (n=2, 66%) or insertion of a singular jugular bicaval venous cannula with removal of the femoral cannulas (n=1, 33%). The median time on VA ECMO prior to conversion was 8 days (range 4-54 days). All 3 patients were managed with renal replacement therapy with 1 patient (33%) progressing to long term dialysis. There were no significant ischemic limb complications although one (33%) patient developed a femoral artery pseudoaneurysm that required re-operation. Two of the three patients (66%) were able to be decannulated at a median of 23.5 days (range 8-39 days) following conversion to VV ECMO and survived to discharge. The other patient was unable to be decannulated after successful conversion and care was withdrawn. Conclusion(s): Based on this small pilot study, conversion to VV ECMO from initial femoral VA ECMO cannulation is safe and feasible. Indications for conversion include coagulopathy and need for extended ECMO run after recovery of cardiac function.
ABSTRACT
BACKGROUND: COVID-19 as a pandemic has caused an alarming increase in mortality and morbidity. Viral-induced morphologic changes in the peripheral blood cells are well characterized in certain infections and can direct diagnostic workup to ensure timely therapeutic intervention. This study describes the morphological changes of blood cells in various stages of COVID disease. MATERIALS AND METHODS: A total of thousand COVID-positive patients admitted in the tertiary care center were taken for the study. They were classified as mild, moderate, and severe based on the clinical criteria suggested by World Health Organization. Peripheral smears of the patients were analyzed, and the morphological changes in various blood cells were correlated with the disease stage and coagulation parameters. RESULT(S): The study demonstrated significant morphological changes in the blood cells of COVID patients during the course of disease progression and during the onset of COVID-associated coagulopathy. Leukocytosis, neutrophilia, and toxic changes in neutrophils were seen in the severe stage of the disease and in COVID coagulopathy suggesting these are important indicators of disease severity. Activated lymphocyte was found to be the most common morphological presentation seen in all patients irrespective of the disease stage, whereas plasmacytoid lymphocytes were an important finding in severe-stage disease. Schistocytes an important finding in any other coagulopathy was present only in 1% of cases of COVID coagulopathy. CONCLUSION(S): The study demonstrated significant morphological changes in the blood cells of COVID-positive patients during the course of disease progression. Comprehensive daily complete blood count and peripheral smear examination should be undertaken in patients hospitalized with COVID-19 to predict potential clinical deterioration and signs of disease progression. These morphological changes in peripheral smear can be used as one of the factors indicating disease progression which can formulate for further evaluation. Since follow-up and post-COVID morphological examination were not done, additional research in this aspect can shed light on the clinical categorization of COVID patients based on the morphological findings.Copyright © 2023 Journal of Applied Hematology Published by Wolters Kluwer - Medknow.
ABSTRACT
Introduction: Ivermectin is an antiparasitic medication that is primarily metabolized by the liver. During the COVID-19 pandemic, researchers demonstrated that Ivermectin successfully inhibited the replication of SARS-COV-2 in vivo, but current research has failed to demonstrate clinical benefit for treatment of COVID-19. Despite this, misinformation campaigns have misled patients to ingest Ivermectin at concentrations meant for domestic animals. Here, we present a case of acute liver failure secondary to the use of Ivermectin. Case Description/Methods: A 61-year-old man with medical history of ischemic cardiomyopathy with last echocardiogram showing ejection fraction at 21%, atrial fibrillation on warfarin for oral anticoagulation, and previously treated Hepatitis C presented with generalized weakness and yellowish discoloration of the skin worsening over the last two weeks. The patient denied significant alcohol use, acetaminophen use, or illicit drugs. He admitted to injecting himself with two doses of weight-based horse ivermectin, for COVID prophylaxis, two weeks prior to his presentation. Physical exam was pertinent for scleral icterus and hepatomegaly with no abdominal tenderness. Initial labs revealed elevated liver chemistries in a mixed pattern (Figure 1). Acute hepatitis panel, HSV, and CMV were negative. Hepatitis C antibodies were positive, but the patient was in sustained virologic response. Full workup for chronic liver disease was unremarkable. Ultrasound revealed hepatosplenomegaly with patent portal and hepatic vasculature. Subsequently, the patient developed hepatic encephalopathy along with his coagulopathy, raising concern for acute hepatic failure. The patient was transferred to the ICU and started on NAcetylcysteine, rifaximin, and supportive care. The patient recovered well and fortunately did not require liver transplant. Discussion(s): While the FDA recommends against the use of Ivermectin for COVID-19, many continue to inappropriately consume it. Ivermectin-induced liver failure is a rare but deadly side effect. Given our patient's rapid onset of symptoms post-self injection of Ivermectin, his liver injury was presumed to be related to Ivermectin. The drug interaction between Ivermectin and warfarin had worsened the patients coagulopathy. Physicians should be aware of the ways Ivermectin overdose may clinically present to avoid delayed treatment. This case demonstrates the detriments of perpetuation of medical misinformation to care.
ABSTRACT
The Novel Coronavirus Disease (COVID-19) is characterized by a variety of clinical manifestations, including a predominant lesion of the respiratory system with the possible development of distress syndrome, the development of multiple organ failure. COVID-19 can cause depression, anxiety, and other emotional disorders, which may interfere with subsequent physical recovery. The aim - clinical analysis of emotional disorders in patients with the Novel Coronavirus Infection (COVID-19). Material and methods. A retrospective analysis of electronic medical records of 124 patients admitted to the infectious diseases department of Chelyabinsk City Clinical Hospital No. 8 in 2020-2021 was carried out. The methods of clinical and psychological research (including clinical conversation, observation and testing using the "Hospital Scale of Anxiety and Depression" HADS and the "Symptom Check List" SCL-90-R) were used to identify the features of the emotional states of patients with COVID-19. Statistical analysis was performed using the statistical package <<Statistica 6.0>>. The Spearman rank correlation coefficient was used. Results. Typical complaints upon admission to the hospital are fever, cough, general weakness, loss of smell and taste, runny nose. The majority of patients showed elevated levels of C-reactive protein and protein of the acute phase of inflammation - ferritin, an increase in the D-dimer by more than 2.5 times compared with the average standard values, a decrease in the value of the prothrombin index (mean value 88.7+/-6.4%) indicate coagulopathy as a manifestation of hyperinflammation that develops in COVID-19. More than half of patients (52.08+/-9.42%) experienced psychological distress of moderate and high severity: an increased level of distress was recorded in 42.78+/-9.33% of the examined patients, a high level of distress was found in 9.30+/-5.48% of patients. Direct correlations of varying degrees of strength between general somatic distress and indicators of anxiety, depression, psychopathological manifestations (obsessive-compulsiveness and interpersonal sensitivity) and mental distress were identified. Revealed negative emotional experiences in patients with COVID-19 can cause adverse effects on the course and prognosis of the disease, reduce adherence to treatment, negatively affect the social functioning and quality of life of patients.Copyright © Infectious Diseases: News, Opinions, Training 2022.

ABSTRACT
Introduction: COVID-19 coagulopathy is associated with poor prognosis and a state of coexisting 'hypercoagulopathy' (HyperC) and hypofibrinolysis, only detected by viscoelastic tests (VET). VET technology has been useful in areas where conventional tests are inadequate, such as screening for HyperC, thrombotic risk assessment and systemic anticoagulants' effect. We aim to characterize the evolution profile of coagulopathy in patients with COVID-19 infection during their intensive care unit (ICU) stay. Method(s): Consecutive recruitment of adult COVID-19 patients admitted to our hospital's ICU, during a 6 months period. Patients with thrombosis in the previous 3 months, pregnancy, under hormone therapy, and congenital coagulopathies were excluded. VET were executed every 5 days, at discharge and in complications and all of them were under low weight molecular heparin (LMWH) therapy. Group 1 (G1), n = 24-less than 10 days in ICU and group 2 (G2), n = 16-more than 10 days in ICU. In G1 there was 1 death (day 3) and in G2 there were 5 deaths (between days 15 and 42). We focused current analysis on VET-Rotem parameters (see Fig. 1). Result(s): Prognostic scores APACHE II, SAPS II and SOFA were higher in G2, but surprisingly G1 patients are more obese. G2 patients had shorter aPTT and lower platelets. The variables CT-HepTem and MCF Extem-MCF-Fib-Tem present a greater difference between groups, but no statistical significance. We observed an initial correlation between basophils number (which is lower) on CT Intem and CT Hep-Tem, lost as progression to cure, probably due to cytoplasm heparin granules. As expected, VET were in accordance with HyperC: short CTs, increased MCFs, and decreased lysis. Conclusion(s): We expected to guide/adjust LMWH dosage, using Rotem profiles, however these were not corrected by LMWH, used transversally, and remained unchanged in all patients during their stay in ICU.
ABSTRACT
COVID-19 is routinely associated with coagulopathy and complications associated with thrombosis. However, the difference between the coagulopathy, which is associated with COVID-19 and the coagulopathy, which is due to different causes, is that the "COVID-19 associated coagulopathy" shows raised levels of D-Dimer and that of fibrinogen. However, it shows quite some abnormalities in the levels of prothrombin time and also in the platelet count. "Venous thromboembolism" and arterial thrombosis is frequently seen in COVID-19 associated coagulopathy as opposed to "disseminated intravascular coagulopathy". Patients suffering from COVID-19 have many have multiple factors in common for thromboembolism which is associated with "Adult respiratory distress syndrome" from different etiologies like generalized inflammation and being unambulatory. "Cytokine storm" is the hallmark of COVID-19 associated coagulopathy which is distinguished by high levels of IL-6,1, tumour necrosis factor and other cytokines. The clinical features of COVID-19 associated coagulopathy overlap that of some syndromes like antiphos-pholipid syndrome and thrombotic microangiopathy. Studies have shown that patients diagnosed with disseminated intravascular coagulation have a poor prognosis compared to the one's that don't get diagnosed with DIC. The advancement of the condition from coagulopathy in the vasculature of the lungs to DIC in patients who have tested positive for COVID-19 shows that the patient's dysfunction associated with coagulation has evolved from local to generalized state. Investigating the coagulopathies will help in understanding the mechanism of COVID-19 associated coagulopathy.Copyright © International Journal of Research in Pharmaceutical Sciences.
ABSTRACT
Coronaviruses are a large family of single-stranded ARN viruses that infect a wide variety of animals, including humans. The SARS-CoV-2 virus, which is responsible for the disease called COVID-19, has infected 27,249,308 people and caused 890,971 deaths worldwide until September 7, 2020. Considering the genetic similarities between SARS-CoV-2 and the epidemic coronaviruses SARS-CoV and MERS, presumably they share tropisms for specific cell lines and systemic conditions. The clinical and paraclinical characteristics of this new virus have been described in detail at the pulmonary level, although there is increasing evidence that it is a multisystemic agent. In the present work, we describe the extrapulmonary manifestations of COVID-19 reported to date, including hematological, cardiovascular, neurological, renal, muscular, ophthalmological, endocrine-metabolic, gastrointestinal, hepatobiliary, cutaneous and in special populations: pediatric (including multisystemic inflammatory syndrome) and pregnant women. It is essential to know the systemic complications of SARS-CoV-2 infection when managing these patients, given the potential risk to life of the most serious manifestations. Therefore, it is advisable to consider them in a targeted manner and provide timely treatment as far as possible.Copyright © 2022 Comunicaciones Cientificas Mexicanas S.A. de C.V..
