Today, hepatitis B virus-associated acute liver failure remains the leading cause of liver failure (44% mortality in Asia and 41% in the United States). Studies show that among patients with hepatitis B-associated cirrhosis, acute liver failure develops in 10-20% of cases. Acute liver failure on chronic liver disease is a potentially reversible syndrome that occurs in patients with cirrhosis or chronic liver disease and is characterized by acute decompensation, organ failure, and high short-term mortality. Chronic hepatitis B virus infection is a leading cause of liver morbidity and mortality worldwide. When we talk about hepatitis B, there is a high risk of developing super infection hepatitis D, since hepatitis D remains infectious and can reactivate at very low titers that are not detected using modern analysis methods if HBsAg remains in the blood serum. The interaction of these viruses leads to accelerated progression of fibrosis and cirrhosis of the liver, which significantly increases the risk of developing acute liver failure against the background of chronic. In our case, a patient diagnosed with liver cirrhosis as a result of viral hepatitis B with delta agent, class C according to Child–Pugh–Turcotte, MELD-36 points, the patient developed a severe form of acute renal failure, which required emergency intervention, so he was not included in the waiting list for a transplant from a cadaveric donor. His wife became the donor, which is an example of living donation, which provides higher chances of successful recovery due to a shorter waiting time and a lower risk of graft rejection. Timely examination of the donor and recipient, as well as prompt liver transplantation, contributed to a favorable outcome of the disease.

IntroductionChronic obstructive pulmonary disease is a lung condition characterized by chronic respiratory symptoms (breathlessness, cough, and expectoration). In the advanced stages, patients often report to the Accident & Emergency department due to worsening of symptoms. Because of the repeated exposure to corticosteroids during the management of exacerbations, these patients are susceptible to super additional infections. Pulmonary aspergillosis can be divided into three main categories: invasive pulmonary aspergillosis, allergic bronchopulmonary aspergillosis and chronic pulmonary aspergillosis. Aspergillus overlap syndrome is defined as the presence of more than one form of Aspergillus in a single patient. However, coinfection with Klebsiella and pulmonary aspergillosis overlap syndrome is rare and poses a treatment challenge. As per a pub med search, no such case report has been reported in a case of chronic obstructive pulmonary disease.Case reportWe report the case of a 66-year-old male, Punjabi Hindu by ethnicity, who was a reformed smoker with a known case of COPD. He presented with a history of breathlessness (mMRC grade 4) associated with cough with expectoration and wheezing for 15 days and intermittent episodes of hemoptysis for more than 6 months. The examination revealed tachypnea and wheezing throughout the lung fields. He was initially managed with parenteral steroids and frequent nebulization with bronchodilators. On day 5 of hospitalization, the patient experienced worsening of symptoms and cardiac arrest; he was intubated and return of spontaneous circulation was achieved within 5 minutes of cardio pulmonary resuscitation. Tracheal aspirate and culture revealed Aspergillus fumigatus and Klebsiella pneumoniae respectively. He underwent chest CT, which showed features suggestive of allergic bronchopulmonary aspergillosis and invasive pulmonary aspergillosis. He was found to have elevated β-d-glucan, galactomannan, and aspergillus IgE and IgG. Severe pneumonia and pulmonary Aspergillus overlap syndrome were managed with antibiotics, steroids, and antifungals. Over the next 15–20 days, his general condition improved. He was discharged after 45 days of hospitalization and continued on oral corticosteroids, antifungals, and inhaled bronchodilators.ConclusionCoinfection with bacteria and fungi worsens the outcome. Clinicians should be aware of the polymicrobial manifestations and various drug interactions involved. Timely diagnosis aids in better management strategies and improved patient outcomes.

A study of outcome of diaphyseal fractures of radius and ulna in paediatric age group treated with titanium elastic nailing system. The current study is an attempt to find out the functional outcome, radiological union, and complications of paediatric diaphyseal radius and ulna fracture treated with titanium elastic nail. This is a prospective study of twenty-five patients of age group 6 years to 16 years diagnosed with a diaphyseal fracture of radius and ulna treated with percutaneous nailing with titanium elastic nails in Department of Orthopaedics, S Nijalingappa Medical College and HSK Hospital, Bagalkot between November 2019 to April 2022. Clinical, functional and radiological outcomes were assessed with Anderson et al criteria for 6 months. In terms of union and range of motion using Anderson et al criteria 20 patients had excellent results, 2 patients had satisfactory results and one patient had an unsatisfactory result. There were no cases of poor results. Five cases had complications like Nail prominence, elbow stiffness, olecranon bursitis and super skin infection. The radiological union was achieved in a mean time of 8.24±2.62 weeks. Complications resolved after implant removal. Titanium elastic nail system showed excellent results in terms of bony union, functional outcome with minimal complications which resolve after nail exit. Therefore, titanium elastic nail system should be considered as an effective alternative of conservative management for forearm fractures in pediatric age group.

In 2019 the World Health Organization (WHO) listed antimicrobial resistance among the top 10threats to global health. The Seraph® 100 Microbind® Affinity blood filter (Seraph® 100) has been in use since 2019 to eliminate pathogens from the bloodstream in addition to anti-infective pharmacotherapy. It is the first device used to rapidly and efficiently reduce the number of circulating bacteria and viruses. After abackground on the concept of extracorporeal pathogen removal in general, this review summarizes the preclinical and clinical data on the Seraph® 100 Affinity Blood Filter. The clinical effect of this treatment and potential therapeutic options are described. Structured PubMed review including references published up to February 2024. Case reports, uncontrolled observational studies and data from registries show widespread clinical use of the Seraph® 100 ranging from difficult to treat bacterial (super) infections to viral infections. The treatment can be done as stand-alone hemoperfusion or in combination with all forms of kidney replacement therapy as well as in extracorporeal membrane oxygenation. The use of the Seraph® 100 varies in terms of duration, concomitant therapy and clinical settings. Due to the absence of prospective controlled trials the clinical effect cannot be properly evaluated.

The literature on the association of Co-infection and Super infection in patients with SARS-COV2 infection is reviewed in this paper. Co-infection is defined by the Centers for Disease Control and Prevention in the United States as an infection that occurs in the human body when the person is already afflicted with multiple diseases. Super infection is another phrase used by the Centers for Sickness Control and Prevention to describe a disease caused by the same virus but with a different strain each time. Over a lengthy period of time, it has been seen that a patient's viral respiratory infection develops to bacterial infection, which can be fatal. However, the association between the two remains a mystery for the researchers. In the case of COVID-19 viruses, comparable results have been obtained. The extensive spectrum of Co-infections and Super infections in Corona patients has been documented in a number of articles.

Discovery and druggability evaluation of pyrrolamide-type GyrB/ParE inhibitor against drug-resistant bacterial infection

Background: Despite acute hepatitis E virus (HEV) infection is a self-limiting acute infection, it could be a cause of acute on top of chronic liver failure (ACLF) in patients with chronic liver disease. Thus, identification role of HEV superinfection in deterioration of liver cirrhosis with early treatment could save life of those patients. Aim: To determine the percentage and the role of HEV infection in order to detect outcomes of patients with ACLF, to find effect of HEV infection on liver, kidney functions and coagulation profile, and to find specific clinical or laboratory characteristics of these patients if present.

Infections by filamentous phages, which are usually nonlethal to the bacterial cells, influence bacterial fitness in various ways. While phage-encoded accessory genes, for example virulence genes, can be highly beneficial, the production of viral particles is energetically costly and often reduces bacterial growth. Consequently, if costs outweigh benefits, bacteria evolve resistance, which can shorten phage epidemics. Abiotic conditions are known to influence the net-fitness effect for infected bacteria. Their impact on the dynamics and trajectories of host resistance evolution, however, remains yet unknown. To address this, we experimentally evolved the bacterium Vibrio alginolyticus in the presence of a filamentous phage at three different salinity levels, that is (1) ambient, (2) 50% reduction and (3) fluctuations between reduced and ambient. In all three salinities, bacteria rapidly acquired resistance through super infection exclusion (SIE), whereby phage-infected cells acquired immunity at the cost of reduced growth. Over time, SIE was gradually replaced by evolutionary fitter surface receptor mutants (SRM). This replacement was significantly faster at ambient and fluctuating conditions compared with the low saline environment. Our experimentally parameterized mathematical model explains that suboptimal environmental conditions, in which bacterial growth is slower, slow down phage resistance evolution ultimately prolonging phage epidemics. Our results may explain the high prevalence of filamentous phages in natural environments where bacteria are frequently exposed to suboptimal conditions and constantly shifting selections regimes. Thus, our future ocean may favour the emergence of phage-born pathogenic bacteria and impose a greater risk for disease outbreaks, impacting not only marine animals but also humans.

Hepatitis A super infection can cause severe or even fatal illness in patients with chronic liver disease. Here, we describe a ten-year-old boy who was admitted for acute hepatitis A virus infection but later on he was diagnosed with Wilson disease. Wilson disease was diagnosed on the basis of low ceruloplasmin, high urinary copper excretion, and the presence of K-F ring. Hepatitis A was diagnosed by the presence of antibody in the blood. This case report suggests that acute hepatitis A virus infection may play a role in acute decompensation in diagnosed or undiagnosed chronic liver disease.

Viral Hepatitis causing approximately 1.4 million deaths every year. HBV is a partially double stranded DNA virus and belongs to the family Hepadnaviridae. HDV is a sub satellite virus which infects patients that are already infected by HBV because it depends on HBV surface antigen for its replication. HDV causes super infection with different complexities as compared to sole HBV infection.To compare viral load of HBV and HDV to check possible influence on each others replication.A cross-sectional analytical study was conducted on 907 samples. HBV DNA was detected and quantified by Abbott HBV Quantification kit and HDV RNA was detected and amplified by RoboGene®. Screening of HDV RNA and HBV DNA by PCR and results were analyzed using SPSS. Out of 907 patients, 33% were HBV/HDV co-infected, 35% were HBV, 18% were infected with HDV & 14% were HBV/HDV negative.Out of these, 75.7% were males and 24.3% were females. The patients were divided into three age groups: 5-20 years, 21-40 years & 41-80 years. Overall levels of HBV DNA PCR < 1000 IU/ml was found in 74% HBV/HDV co-infected patients as compared to 30.8% HBV mono infected. This study indicates that the absence or the low viral load of HBV in HDV positive patients might be due to possible subdue of HBV by HDV in HBV/HDV co-infected patients.Age group of 20-40 years and male gender is comparatively at high risk for these viral infections.

Gastrointestinal endoparasite is an infection that causes a decrease in the productivity level of sheep so that it detriments to the farmers. The purpose of this study was to compare the type, the prevalence and the intensity of endoparasites in each age group. Samples were taken as many as 7 fresh feces from each group of lamb, virgin, and adult from a total of 21 sheeps. Fecal samples were examined and prepared using the E.P.M Mc Master Protocol while endoparasites were identified under microscopical examination. The results showed 5 species of gastrointestinal endoparasites, i.e Eimeria sp., Dicrocoelium sp., Haemonchus sp., Strongyloides sp., and Capillaria sp. Eimeria sp. showed a prevalence of 85.7% in commonly category and intensity of 2216.6 or super infection category. Haemonchus sp. had a prevalence of 85% (common), an intensity of 671.4 (very severe), and the Strongyloides sp. had a prevalence of 85% (common) and an intensity of 200 (very severe). The lambs were found to be infected by Eimeria sp. with a prevalence of 100% (common) and an intensity of 2871.4 (super infection). Haemonchus sp. had a prevalence of 100% (common) and an intensity of 1200 (super infection), Strongyloides sp. had a prevalence of 71% (usual) and an intensity of 860 (very severe) and the Dicrocoelium sp. had a prevalence of 14% (often) and an intensity of 400 (very severe). The adult sheeps were found to had Eimeria sp. with a prevalence of 100% (common) and an intensity of 371.4 (very severe). The Haemonchus sp. had a prevalence of 14% (often) and an intensity of 200 (very severe). Strongyloides sp. had a prevalence of 57% (frequent) and an intensity of 200 (very severe) and the Capillaria sp. had a prevalence of 14% (often) and an intensity of 100 (severe). The prevalence and intensity of endoparasites in sheeps at Arjuna Farm was classified as very high.

Gastrointestinal parasitic infections can cause horses to experience diarrhea, weight loss, weakened physical condition and even death. This horse disease is a great danger that can reduce horse performance.The research on the description of gastrointestinal endoparasites in Sumba horses (Equus caballus) at Citra Pesona Ladangku animal park, Pancur Batu, Deli Serdang, North Sumatra. The aim of the study was to determine the type of endoparasites, prevalence and the intensity of parasite attacks. The sample testing was carried out at the Parasitology Laboratory, Medan Veterinary Center using the EPG Mc. Masters method. The results showed that from 18 Sumba horses examined, 6 types of endoparasites were found, namely Strongylus sp., Trichonema sp., Dictyocaulus arnfieldi, Strongyloides sp., Triodontophorus sp. and Ascaris sp. The prevalence of Strongylus sp. was 86% in the usual category and the intensity attack was 1.530 in the Super infection category, Dictyocaulus arnfieldi was 53% in the frequent category and the intensity attack was 1.161 in the Super infection category, Trichonema sp. was 38% in the common category, and the intensity attack 300 categorized in the very severe category, Strongyloides sp. was 22% in the often category and the intensity was 430 in the very severe category, Triodontophorus sp. was 16% in the often category and the intensity was 500 in the very severe category and Ascaris sp. had prevalence 14% in the often category and the intensity was 100 in the severe category. The gastrointestinal parasitic infections in Sumba horses need special attention.

Pathogens vary strikingly in their virulence and the selection they impose on their hosts. While the evolution of different virulence levels is well studied, the evolution of host resistance in response to different virulence levels is less understood and, at present, mainly based on observations and theoretical predictions with few experimental tests. Increased virulence can increase selection for host resistance evolution if the benefits of avoiding infection outweigh resistance costs. To test this, we experimentally evolved the bacterium Vibrio alginolyticus in the presence of two variants of a filamentous phage that differ in their virulence. The bacterial host exhibited two alternative defence strategies: (1) super infection exclusion (SIE), whereby phage-infected cells were immune to subsequent infection at the cost of reduced growth, and (2) surface receptor mutations (SRM), providing resistance to infection by preventing phage attachment. While SIE emerged rapidly against both phages, SRM evolved faster against the high- than the low-virulence phage. Using a mathematical model of our system, we show that increasing virulence strengthens selection for SRM owing to the higher costs of infection suffered by SIE immune hosts. Thus, by accelerating the evolution of host resistance, more virulent phages caused shorter epidemics.

Mucormycosisis an opportunistic fungal disease which affects immunocompromised hosts including patients with haematologic malignancies and poorly controlled diabetes mellitus. Mucorales grow invasively and are associated with high mortality even if promptly diagnosed. Viral infection like influenza can cause severe pneumonia and is associated with pulmonary aspergillosis. Here we report three separate cases of Mucorales super infection in critically-ill patients with influenza infection, one of them histologically confirmed. Two patients also had influenza-associated pulmonary aspergillosis. Two patients had fatal clinical outcome despite intensive care. The simultaneous detection of these two rare mold infections in patients with severe influenza is highly remarkable and calls for increased awareness.

ObjectiveChronic HBV/HDV infections are a major cause of liver cancer. Current treatments can only rarely eliminate HBV and HDV. Our previously developed preS1-HDAg immunotherapy could induce neutralising antibodies to HBV...

Background: In December 2019, the new corona virus initially appeared in Wuhan, China, and has since spread to other nations around the world. On January 30, 2020, the World Health Organization believes that the new CoV-19 outbreak will be declared a public health emergency of international concern (PHEIC) by the World Health Organization. The mortality rate of this viral infection varies widely around the world, from 2% in Pakistan to 14.4% in Italy. In the early stages of the disease, lympopenia, raised transminase, proteinuria, increased LDH, and C-reactive protein levels are all common laboratory results. Patients treated with Covid have had severe pneumonia, ARDS, heart defects, sepsis and septic shock, and respiratory tract super infection, among other problems. Methodology: The Gynecology unit of the Saidu Group of Teaching Hospitals conducted this retrospective observational research study. Biochemical and radiological parameters of medical history, test findings, symptoms, pregnancy, and neonatal outcomes were noted in a pre-constructed data collection form. The study excluded patients who was treated in an outpatient setting. Results: There were a total of 121 patients, with a mean age of 27 and a standard deviation of 5, with a range of 19-40 years. Pregnant women reported their first pregnancy in 48.3% of cases (primigravida). 51.3 percent of SARS-Cov-2 patients were in their third trimester, whereas 34.7 percent were between 35 and 40 weeks of pregnancy. Pregnancy-induced hypertension (PIH) (16 instances), hypothyroidism (14 cases), and gestational diabetes (GDM) (9 cases) are the most common problems. More than half of the patients (53%) are asymptomatic. Cough (22 percent) and fever (11 percent) are the most common symptoms (11 percent ). As seen in table 1, the incidence of multiple organ failure was 2%. Lympopenia was a prevalent ailment (84 percent ). Bilateral invasion was discovered in a CT scan of 24 subjects. Conclusion: According to our findings, COVID-19 has a deleterious impact on the foetus. Although pregnant women do not appear to be more susceptible to COVID-19 complications than non-pregnant adults, previous research has suggested that pregnant women may be more at risk for negative pregnancy outcomes such as preterm birth, foetal pain and respiration, symptoms, and LBW in a newborn baby. Keywords: Corona virus, COVID-19, pregnancy, outcome.

Introduction: The COVID-19 pandemic has challenged global health with novel pathogenesis that is both severe and poorly understood. Several mechanisms have been proposed to explain the severity and complexity of the clinical illness including cytokine storm release, thromboembolic microangiopathy, direct cytotoxicity, and post-viral bacterial super infection. Cases: The patients in this case series were all admitted to the intensive care unit with respiratory failure from COVID-19 requiring invasive mechanical ventilation. They were all started on anticoagulation. All three patients developed acute kidney injuries. The first patient had hypertensive emergency at the time of the bleed. The second and third patient both had supratherapeutic heparin levels at the time of the bleed. Methods: We followed patients aged 18 years and above who were admitted to the ICU for COVID-19 during April and May 2020. We then followed those who required therapeutic anticoagulation for any indication and evaluated the ones that developed ICH. Results: Out of the 79 patients admitted to the ICU for COVID-19 related illness during April and May 2020, 31 were placed on therapeutic anticoagulation (intermediate or full-dose) for indications that included hypercoagulable state, ACS, atrial fibrillation, and deep vein thrombosis. 25% of patients on anticoagulation developed bleeding for which the anticoagulation had to be stopped. Three out of these 31 patients developed ICH while on anticoagulation, accounting for 3.8% of our ICU population with COVID-19 Discussion: Activation of coagulation pathways during cytokine storms can result in systemic thromboembolism, in both venous and arterial circulations posing risk of ischemic infarctions to any organ. Supratherapeutic heparin levels and acute kidney injuries are common in COVID-19 patients. The ideal candidates for anticoagulation, the recommended agent and dose, and duration of treatment remain unclear. Conclusion: The benefits of anticoagulation should be weighed against the potential risk of bleeding.

Mortality risk and antibiotic use for COVID-19 in hospitalized patients over 80

BackgroundThe rate of bacterial and fungal super-infections (SI) in inpatients with COVID-19 is unknown. In this study, we aimed to identify and describe patients that developed secondary infections while hospitalized with COVID-19.MethodsWe performed a retrospective chart review on patients admitted to our health system between March and May 2020 with confirmed COVID-19 by nasopharyngeal PCR. We reviewed patients with positive cultures from urine, blood, sputum, and sterile sites. Patients with positive cultures had cases reviewed to determine if they represented a true infection, defined by CDC criteria. SIs were defined as infections that occurred at least 48 hours or longer after the initial positive SARS-CoV-2 test. Additional data was collected on patient demographics, COVID-related therapies, types of infections, and outcomes.Results902 patients were admitted with COVID-19 during our study period. Of these, 52 patients (5.8%) developed a total of 82 SIs. Tables 1 and 2 describe patient and infection characteristics. Patients identified as having a SI were admitted for a median of 30 days; 56% had mortality, and 39% of remaining patients were readmitted within 90 days. Table 1. Patient CharacteristicsTable 2. Super-infectionsConclusionOverall, the rate of SIs in patients admitted with COVID-19 is low. These patients had a long length of stay, which may be either a cause of SI or an effect. Further analysis with matched COVID-positive control patients who do not develop SIs is needed to evaluate the risk of development of SIs in relation to presenting respiratory status, COVID-related therapies, and other patient-specific factors.DisclosuresJason C.
