RESUMO

The COVID-19 outbreak is becoming a public health emergency. Data are limited on the clinical characteristics and causes of death. A retrospective analysis of COVID-19 deaths were performed for patients' clinical characteristics, laboratory results, and causes of death. In total, 56 patients (72.7%) of the decedents (male-female ratio 51:26, mean age 71 ± 13, mean survival time 17.4 ± 8.4 days) had comorbidities. Acute respiratory failure (ARF) and sepsis were the main causes of death. Increases in C-reactive protein (CRP), lactate dehydrogenase (LDH), D-dimer and lactic acid and decreases in lymphocytes were common laboratory results. Intergroup analysis showed that (1) most female decedents had cough and diabetes. (2) The proportion of young- and middle-aged deaths was higher than elderly deaths for males, while elderly decedents were more prone to myocardial injury and elevated CRP. (3) CRP and LDH increased and cluster of differentiation (CD) 4+ and CD8+ cells decreased significantly in patients with hypertension. The majority of COVID-19 decedents are male, especially elderly people with comorbidities. The main causes of death are ARF and sepsis. Most female decedents have cough and diabetes. Myocardial injury is common in elderly decedents. Patients with hypertension are prone to an increased inflammatory index, tissue hypoxia and cellular immune injury.

RESUMO

Severe acute respiratory syndrome coronavirus 2 is a novel cause of organ dysfunction in children, presenting as either coronavirus disease 2019 with sepsis and/or respiratory failure or a hyperinflammatory shock syndrome. Clinicians must now consider these diagnoses when evaluating children for septic shock and sepsis-associated organ dysfunction. The Surviving Sepsis Campaign International Guidelines for the Management of Septic Shock and Sepsis-associated Organ Dysfunction in Children provide an appropriate framework for the early recognition and initial resuscitation of children with sepsis or septic shock caused by all pathogens, including severe acute respiratory syndrome coronavirus 2. However, the potential benefits of select adjunctive therapies may differ from non-coronavirus disease 2019 sepsis.

RESUMO

BACKGROUND: Observational studies of the ongoing coronavirus disease 2019 (COVID-19) outbreak suggest that a 'cytokine storm' is involved in the pathogenesis of severe illness. However, the molecular mechanisms underlying the altered pathological inflammation in COVID-19 are largely unknown. We report here that toll-like receptor (TLR) 4-mediated inflammatory signaling molecules are upregulated in peripheral blood mononuclear cells (PBMCs) from COVID-19 patients, compared with healthy controls (HC). METHODS: A total of 48 subjects including 28 COVID-19 patients (8 severe/critical vs. 20 mild/moderate cases) admitted to Chungnam National University Hospital, and age/sex-matched 20 HC were enrolled in this study. PBMCs from the subjects were processed for nCounter Human Immunology gene expression assay to analyze the immune related transcriptome profiles. Recombinant proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) were used to stimulate the PBMCs and monocyte-derived macrophages, and real-time polymerase chain reaction was performed to quantify the mRNA expressions of the pro-inflammatory cytokines/chemokines. RESULTS: Among the most highly increased inflammatory mediators in severe/critically ill patients, S100A9, an alarmin and TLR4 ligand, was found as a noteworthy biomarker, because it inversely correlated with the serum albumin levels. We also observed that recombinant S2 and nucleocapsid proteins of SARS-CoV-2 significantly increased pro-inflammatory cytokines/chemokines and S100A9 in human primary PBMCs. CONCLUSION: These data support a link between TLR4 signaling and pathological inflammation during COVID-19 and contribute to develop therapeutic approaches through targeting TLR4-mediated inflammation.

RESUMO

Recently, the stabilization of the endothelium has been explicitly identified as a therapeutic goal in coronavirus disease 2019 (COVID-19). Adrecizumab (HAM8101) is a first-in-class humanized monoclonal anti-Adrenomedullin (anti-ADM) antibody, targeting the sepsis- and inflammation-based vascular and capillary leakage. Within a "treatment on a named-patient basis" approach, Adrecizumab was administered to eight extreme-critically ill COVID-19 patients with acute respiratory distress syndrome (ARDS). The patients received a single dose of Adrecizumab, which was administered between 1 and 3 days after the initiation of mechanical ventilation. The SOFA (median 12.5) and SAPS-II (median 39) scores clearly documented the population at highest risk. Moreover, six of the patients suffered from acute renal failure, of whom five needed renal replacement therapy. The length of follow-up ranged between 13 and 27 days. Following the Adrecizumab administration, one patient in the low-dose group died at day 4 due to fulminant pulmonary embolism, while four were in stable condition, and three were discharged from the intensive care unit (ICU). Within 12 days, the SOFA score, as well as the disease severity score (range 0-16, mirroring critical resources in the ICU, with higher scores indicating more severe illness), decreased in five out of the seven surviving patients (in all high-dose patients). The PaO2/FiO2 increased within 12 days, while the inflammatory parameters C-reactive protein, procalcitonin, and interleukin-6 decreased. Importantly, the mortality was lower than expected and calculated by the SOFA score. In conclusion, in this preliminary uncontrolled case series of eight shock patients with life-threatening COVID-19 and ARDS, the administration of Adrecizumab was followed by a favorable outcome. Although the non-controlled design and the small sample size preclude any definitive statement about the potential efficacy of Adrecizumab in critically ill COVID-19 patients, the results of this case series are encouraging.

RESUMO

The world's most consequential pathogens occur in regions with the fewest diagnostic resources, leaving the true burden of these diseases largely under-represented. During a prospective observational study of sepsis in Takeo Province Cambodia, we enrolled 200 patients over an 18-month period. By coupling traditional diagnostic methods such as culture, serology, and PCR to Next Generation Sequencing (NGS) and advanced statistical analyses, we successfully identified a pathogenic cause in 46.5% of our cohort. In all, we detected 25 infectious agents in 93 patients, including severe threat pathogens such as Burkholderia pseudomallei and viral pathogens such as Dengue virus. Approximately half of our cohort remained undiagnosed; however, an independent panel of clinical adjudicators determined that 81% of those patients had infectious causes of their hospitalization, further underscoring the difficulty of diagnosing severe infections in resource-limited settings. We garnered greater insight as to the clinical features of severe infection in Cambodia through analysis of a robust set of clinical data.

RESUMO

Studies have obtained conflicting findings regarding the association between the interleukin-1ß (IL-1ß) +3954 C>T polymorphism and the risk of sepsis. To evaluate the association between the IL-1ß +3954 C>T polymorphism and sepsis risk in Chinese individuals, we conducted a study of 254 sepsis patients and 322 controls. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for genotyping. We found that the IL-1ß +3954 C>T polymorphism was associated with a reduced risk of sepsis. Subgroup analyses revealed that this significant association was more evident among nonsmokers, nondrinkers, individuals with body mass index <25, and individuals aged ≥60 years. The IL-1ß +3954 C>T polymorphism was also associated with the 28-day mortality rate and severity of sepsis. In summary, the IL-1ß +3954 C>T polymorphism confers a reduced risk of sepsis in Han Chinese. This polymorphism may serve as a marker that predicts patients' susceptibility to sepsis.

RESUMO

BACKGROUND: Decline in mitochondrial function occurs with aging and may increase mortality. We discuss mitochondrial contribution to Covid-19 sepsis, specifically the complex interaction of innate immune function, viral replication, hyper-inflammatory state, and HIF-α/Sirtuin pathways. METHODS: Articles from PubMed/Medline searches were reviewed using the combination of terms "SARS-CoV-2, Covid-19, sepsis, mitochondria, aging, and immunometabolism". RESULTS: Evidence indicates that mitochondria in senescent cells may be dysfunctional and unable to keep up with hypermetabolic demands associated with Covid-19 sepsis. Mitochondrial proteins may serve as damage-associated molecular pattern (DAMP) activating innate immunity. Disruption in normal oxidative phosphorylation pathways contributes to elevated ROS which activates sepsis cascade through HIF-α/Sirtuin pathway. Viral-mitochondrial interaction may be necessary for replication and increased viral load. Hypoxia and hyper-inflammatory state contribute to increased mortality associated with Covid-19 sepsis. CONCLUSIONS: Aging is associated with worse outcomes in sepsis. Modulating Sirtuin activity is emerging as therapeutic agent in sepsis. HIF-α, levels of mitochondrial DNA, and other mitochondrial DAMP molecules may also serve as useful biomarker and need to be investigated. These mechanisms should be explored specifically for Covid-19-related sepsis. Understanding newly discovered regulatory mechanisms may lead to the development of novel diagnostic and therapeutic targets.

RESUMO

BACKGROUND: Listeriosis is a rare but severe foodborne infectious disease. Perinatal listeriosis is often associated with septicemia, central nervous system (CNS) infection, and serious adverse pregnancy outcomes (miscarriage and neonate death). Here we report the characteristics and outcomes of perinatal listeriosis cases treated over 6 years at Beijing Obstetrics and Gynecology Hospital (BOGH), the largest maternity hospital in China. METHODS: We retrospectively reviewed the records of laboratory-confirmed, pregnancy-associated listeriosis cases treated from January 1, 2013 to December 31, 2018. The clinical manifestations, laboratory results, perinatal complications and outcomes (post-natal follow-up of 6 months) were investigated. RESULTS: In BOGH, 12 perinatal listeriosis cases were diagnosed based on Listeria monocytogenes positive culture, including 10 single pregnancies and 2 twin pregnancies. The corresponding incidence of pregnancy-associated listeriosis was 13.7/100,000 deliveries. Among those cases, four pregnant women and four newborns had septicemia, and two of the neonates with septicemia also suffered CNS infection. All the maternal patients recovered. Two inevitable miscarriages and four fetal stillbirths occurred. Of the eight delivered newborns, six survived, and two died within 2 days from birth. None of the survivors had neurological sequelae during a 6-month follow-up. The overall feto-neonatal fatality rate was 57.1%; notably, this rate was 100% for infections occurring during the second trimester of pregnancy and only 14.3% for those occurring in the third trimester. CONCLUSIONS: Perinatal listeriosis is associated with high feto-neonatal mortality, and thus, a public health concern. Additional large-scale studies are needed to strengthen the epidemiological understanding of listeriosis in China.

RESUMO

The sepsis is considered as serious clinic-pathological condition related with high rate of morbidity and mortality in critical care settings. In the proposed study, the hydrazides derivatives N-(benzylidene)-2-((2-hydroxynaphthalen-1-yl)diazenyl)benzohydrazides (1-2) (NCHDH and NTHDH) were investigated against the LPS-induced sepsis in rodents. The NCHDH and NTHDH markedly improved the physiological sign and symptoms associated with the sepsis such as mortality, temperature, and clinical scoring compared to negative control group, which received only LPS (i.p.). The NCHDH and NTHDH also inhibited the production of the NO and MPO compared to the negative control. Furthermore, the treatment control improved the histological changes markedly of all the vital organs. Additionally, the Masson's trichrome and PAS (Periodic Acid Schiff) staining also showed improvement in the NCHDH and NTHDH treated group in contrast to LPS-induced group. The antioxidants were enhanced by the intervention of the NCHDH and NTHDH and the level of the MDA and POD were attenuated marginally compared to the LPS-induced group. The hematology study showed marked improvement and the reversal of the LPS-induced changes in blood composition compared to the negative control. The synthetic function of the liver and kidney were preserved in the NCHDH and NTHDH treated group compared to the LPS-induced group. The NCHDH and NTHDH markedly enhanced the Nrf2, HO-1 (Heme oxygenase-1), while attenuated the Keap1 and TRPV1 expression level as compared to LPS treated group. Furthermore, the NCHDH and NTHDH treatment showed marked increased in the mRNA expression level of the HSP70/90 proteins compared to the negative control.

RESUMO

COVID-19 is known for its magical infectivity, fast transmission and high death toll based on the large number of infected people. From the perspective of the clinical manifestation, autopsy examination and pathophysiology, the essence of COVID-19 should be viewed as a sepsis induced by viral infection, and has the essential characteristics as sepsis induced by other pathogens. Therefore, in addition to etiological and supportive treatment, immunomodulatory therapy is also appropriate to severe COVID-19. Although there is still a lack of consensus on immunotherapy for sepsis so far, relatively rich experiences have been accumulated in the past decades, which will help us in the treatment of severe COVID-19. This article will elaborate immunotherapy of sepsis, though it may not be consistent.

RESUMO

Sepsis is one of the leading causes of mortality in intensive care units (ICU). The growing incidence rate of sepsis and its high mortality rate result are very important sociosanitary problems. Sepsis is a result of infection which can cause systemic inflammatory and organ failure. But the pathogenesis and the molecular mechanisms of sepsis is still not well understood. The aim of the present study was to identify the candidate key genes in the progression of sepsis.Microarray datasets GSE28750, GSE64457, and GSE95233 were downloaded from Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) were identified, and function enrichment analyses were performed. The protein-protein interaction network (PPI) was constructed and the module analysis was performed using STRING and Cytoscape. Furthermore, to verify the results of the bioinformatics analyses, the expression levels of selected DEGs were quantified by Reverse Transcription-Polymerase Chain Reaction (RT-PCR) in libobolysaccharide (LPS)-induced Human Umbilical Vein Endothelial Cells (HUVECs) to support the result of bioinformatics analysis.Thirteen hub genes were identified and biological process analysis revealed that these genes were mainly enriched in apoptotic process, inflammatory response, innate immune response. Hub genes with high degrees, including MAPK14, SLC2A3, STOM, and MMP8, were demonstrated to have an association with sepsis. Furthermore, RT-PCR results showed that SLC2A3 and MAPK14 were significantly upregulated in the HUVECs induced by LPS compared with controls.In conclusion, DEGs and hub genes identified in the present study help us understand the molecular mechanisms of sepsis, and provide candidate targets for diagnosis and treatment of sepsis.

RESUMO

Mycobacterium Chimaera is a microorganism that can cause nosocomial infections particularly in patients undergoing cardiac surgery. The specific case presented herein shows an original clinical presentation of the infection: sudden unilateral deafness as a result of septic embolization. Medico-legal experts appointed by the court in a civil liability dispute analyzed the case and submitted their expert opinion. This article analyzes the peculiar and innovative aspect of professional liability that can be attributed to the healthcare facility and the manufacturer of the equipment used in the operating room from a medical-legal point of view.

RESUMO

The COVID-19 pandemic is still raging across the world. Everyday thousands of infected people lost their lives. What is worse, there is no specific medicine and we do not know when the end of the pandemic will come. The nearest global pandemic is the 1918 influenza, which caused about 50 million deaths and partly terminate the World War Ⅰ. We believe that no matter the virus H1N1 for the 1918 influenza or 2019-nCoV for COVID-19, they are essentially the same and the final cause of death is sepsis. The definition and diagnostic/management criteria of sepsis have been modified several times but the mortality rate has not been improved until date. Over decades, researchers focus either on the immunosuppression or on the excessive inflammatory response following trauma or body exposure to harmful stimuli. But the immune response is very complex with various regulating factors involved in, such as neurotransmitter, endocrine hormone, etc. Sepsis is not a kind of disease, instead a misbalance of the body following infection, trauma or other harmful stimulation. Therefore we should re-think sepsis comprehensively with the concept of systemic biology, i.e. inflammationomics.

RESUMO

Enterocutaneous fistula (ECF) is the most serious postoperative life-threating complication of various abdominal surgical interventions. Treatment of patients with ECF is associated with life-threatening complications including sepsis and septic shock, intestinal failure and severe water-electrolyte disorders that causes high mortality rates (35-75% according to national authors and 6-33% according to foreign colleagues). This issue is especially relevant in the cases of enteroatmospheric fistulae and high ECF with loss of intestinal contents of more than 500 ml per day. In the absence of correct conservative therapy, this quickly results progression of sepsis and development of multiple organ failure. Surgery without complex preoperative preparation in this period may be fatal and lead to clinical aggravation and death of patient in early postoperative period. Each patient requires an individual approach. However, there are general principles of treatment too. This literature review describes the main aspects of conservative treatment of patients with enteric fistulae.

RESUMO

BACKGROUND: Profound healthcare challenges confront societies with an increase in prevalence of end-stage renal disease (ESRD), which is one of the leading causes of morbidity and mortality worldwide. Due to several facility and patient related factors, ESRD is significantly associated with increased morbidity and mortality attributed to infections. AIMS AND OBJECTIVE: The aim of this study was to assess systematically the characteristics of patients and risk factors associated with nosocomial infections among ESRD patients undergoing hemodialysis. METHODS: A systematic literature search was performed to identify eligible studies published during the period from inception to December 2018 pertaining to risk factors associated with nosocomial infections among hemodialysis patients. The relevant studies were generated through a computerized search on five databases (PubMed, EBSCOhost, Google Scholar, ScienceDirect and Scopus) using the Mesh Words: nosocomial infections, hospital acquired infections, healthcare associated infections, end stage renal disease, end stage renal failure, hemodialysis, and risk factors. The complete protocol has been registered under PROSPERO (CRD42019124099). RESULTS: Initially, 1411 articles were retrieved. Out of these, 24 were duplicates and hence were removed. Out of 1387 remaining articles, 1337 were removed based on irrelevant titles and/or abstracts. Subsequently, the full texts of 50 articles were reviewed and 41 studies were excluded at this stage due to lack of relevant information. Finally, nine articles were selected for this review. Longer hospital stay, longer duration on hemodialysis, multiple catheter sites, longer catheterization, age group, lower white blood cell count, history of blood transfusion, and diabetes were identified as the major risk factors for nosocomial infections among hemodialysis patients. CONCLUSION: The results of this review indicate an information gap and potential benefits of additional preventive measures to further reduce the risk of infections in hemodialysis population. Moreover, several patient-related and facility-related risk factors were consistently observed in the studies included in this review, which require optimal control measures.

RESUMO

In February 2018, one 54-year-old male patient with severe scald complicated with pneumonia and sepsis was transferred to Qingdao Municipal Hospital from other hospital. Drugs including cephalosporin, vancomycin, and imipenem/cilastatin combined with ciprofloxacin were used successively for anti-infective treatment, with no obvious effect. Multiple bacterial culture results of sputum, blood, and wound exudate showed infection of extensively drug resistant Pseudomonas aeruginosa. On the 4th day of admission, the anti-infective treatment plan was adjusted, and plasma, red blood cell, and albumin were supplemented and nutritional support and symptomatic treatment were performed. At the same time, medication and drug-related adverse reaction were monitored. After treatment for more than 10 days, infection of the patient was effectively controlled and the condition gradually improved. The case suggests that severely burned patients are prone to have serious and fatal systemic infection, irregular use of antibiotics increases the risk of infection of extensively drug resistant bacteria, clear anti-infection idea and effective application of antibacterial drug can help to improve the success rate of infection treatment and are of important value in improving the prognosis of patients with severe burn.

RESUMO

Sodium-glucose co-transporter 2 (SGLT2) inhibitors exhibit impressive cardio-renal benefits in patients with a high cardiovascular risk. Genital yeast infections are important side effects of this class of drugs. We report a case of Candida glabrata sepsis secondary to a Candida infection of the urostomy of a patient on SGLT2 inhibitor therapy. In urostomy patients, one should critically evaluate the risk of mycotic infections against the cardiovascular and glycaemic benefits of SGLT2 inhibition. Urostomy patients without a high cardiovascular risk should not be treated with SGLT2 inhibitors.

RESUMO

PURPOSE: To compare pregnancy outcomes in women with pPROM and a cervical cerclage in whom the cerclage was removed within 24 h and those in whom the cerclage was retained in situ. METHODS: A two-center retrospective cohort study of women with a singleton gestation with pPROM at < 340/7 weeks of gestation in the presence of cervical cerclage (January 1, 2012-July 30, 2016). Maternal and perinatal outcomes were compared between women in whom cerclage was removed within 24 h from pPROM and those in whom cerclage was retained until the onset of delivery. The primary outcome was time from pPROM to delivery. RESULTS: Seventy women met inclusion criteria. Cerclage was left in situ in 47 (67.1%) and removed in 23 (32.9%) women. Women in the cerclage retention group had a higher pPROM-to-delivery interval (7.0 ± 7.2 vs. 6.0 ± 10.9 days, p = 0.03), and were more likely to have a latency period > 48 h (87.2% vs. 65.2%, p = 0.03; aOR 3.9, 95% CI 3.1-4.9) or > 7 days (29.8% vs. 8.7%, p = 0.04; aOR 7.0, 95% CI 2.5-19.6) compared with women in whom cerclage was removed. Furthermore, chorioamnionitis rate was lower in the cerclage retention group compared to cerclage removal group (aOR 0.7, 95% CI 0.5-1.0). There were no differences between the groups in early neonatal sepsis, severe brain injury, or composite neonatal outcome. CONCLUSION: In women with pPROM and cervical cerclage, retention of cerclage may be associated with a longer latency period, and a lower chorioamnionitis rate, without an associated increase in the risk of neonatal infectious morbidity. Presentation information: The abstract of this study was presented as a poster at the 38th SMFM (Society of Maternal and Fetal Medicine) annual meeting, February 2018, Dallas, Texas, USA.
