Systemic Responses

Ichthyophthirius multifiliis is a major pathogen that causes a high mortality rate in trout farms. However, systemic responses to the pathogen and its interactions with multiple organs during the course of infection have not been well described. In this study, dual-organ transcriptomic responses in the liver and head kidney and hemato-serological indexes were profiled under I. multifiliis infection and recovery to investigate systemic immuno-physiological characteristics. Several strategies for massive transcriptomic interpretation, such as differentially expressed genes (DEGs), Poisson linear discriminant (PLDA), and weighted gene co-expression network analysis (WGCNA) models were used to investigate the featured genes/pathways while minimizing the disadvantages of individual methods. During the course of infection, 6,097 and 2,931 DEGs were identified in the head kidney and liver, respectively. Markers of protein processing in the endoplasmic reticulum, oxidative phosphorylation, and the proteasome were highly expressed. Likewise, simultaneous ferroptosis and cellular reconstruction was observed, which is strongly linked to multiple organ dysfunction. In contrast, pathways relevant to cellular replication were up-regulated in only the head kidney, while endocytosis- and phagosome-related pathways were notably expressed in the liver. Moreover, interestingly, most immune-relevant pathways (e.g., leukocyte trans-endothelial migration, Fc gamma R-mediated phagocytosis) were highly activated in the liver, but the same pathways in the head kidney were down-regulated. These conflicting results from different organs suggest that interpretation of co-expression among organs is crucial for profiling of systemic responses during infection. The dual-organ transcriptomics approaches presented in this study will greatly contribute to our understanding of multi-organ interactions under I. multifiliis infection from a broader perspective.

Sepsis is characterized by multiple-organ dysfunction caused by the dysregulated host response to infection. Until now, however, the role of the Wnt signaling has not been fully characterized in multiple organs during sepsis. This study assessed the suppressive effect of a Wnt signaling inhibitor, Wnt-C59, in the kidney, lung, and liver of lipopolysaccharide-induced endotoxemic mice, serving as an animal model of sepsis. We found that Wnt-C59 elevated the survival rate of these mice and decreased their plasma levels of proinflammatory cytokines and organ-damage biomarkers, such as BUN, ALT, and AST. The Wnt/β-catenin and NF-κB pathways were stimulated and proinflammatory cytokines were upregulated in the kidney, lung, and liver of endotoxemic mice. Wnt-C59, as a Wnt signaling inhibitor, inhibited the Wnt/β-catenin pathway, and its interaction with the NF-κB pathway, which resulted in the inhibition of NF-κB activity and proinflammatory cytokine expression. In multiple organs of endotoxemic mice, Wnt-C59 significantly reduced the β-catenin level and interaction with NF-κB. Our findings suggest that the anti-endotoxemic effect of Wnt-C59 is mediated via reducing the interaction between β-catenin and NF-κB, consequently suppressing the associated cytokine upregulation in multiple organs. Thus, Wnt-C59 may be useful for the suppression of the multiple-organ dysfunction during sepsis.

The article analyzes the mechanisms of the development and clinical manifestations of multi-organ dysfunction and multi-organ failure syndrome, which often accompany the severe COVID-19. Moreover, since multiple organ dysfunction during severe COVID-19 may be caused by a cytokine storm resulting from elevated inflammatory mediators, endothelial dysfunction, coagulation disorders, and inflammatory cell infiltration, further studies are needed to determine the exact mechanisms of pathogenesis. Since the involvement of multiple organs in the pathological process of the disease during coronavirus infection is an important and complex medical, mental, tactical, physical, emotional, and economic task for both clinicians and patients and their families, increasing knowledge of the pathological process can help improve outcomes and reduce morbidity and mortality. The review includes some results of our own experience in the treatment of severe cases of coronavirus disease.

Primary amyloidosis is a rare systemic disorder often associated with multiple organ dysfunction. The most common form, light chain amyloidosis, has an estimated age-adjusted incidence of 5.1–12.8 cases per million person-years. Spine involvement is extremely uncommon. We present the case of a young Asian man with newly diagnosed amyloidosis involving the lumbar spine among multiple organs with a pathological vertebral fracture that required urgent spine surgery. We believe this is the first reported case to discuss the perianaesthetic challenges in the management of lumbar spine amyloidosis.

Background: Although primarily a respiratory illness, COVID-19 involves multiple organs when the disease is severe or critical. Hence, we conducted this study to evaluate the incidence of multiple organ dysfunction in COVID-19 patients and its implications on survival. Methods: A retrospective analysis of laboratory-confirmed COVID-19 patients presenting to our center in Dubai, UAE between April 2020 and July 2020. Data was collected from the electronic medical records and analyzed to evaluate multiple organ damage observed during hospital admission. Findings: Five-hundred patients were studied. Overall mean age was 49.5 years (range 13-94), 76% males, 33% diabetics, 31% hypertensives. 97/500 (19.4%) had evidence of single organ damage; 37/500 (7.4%) had two organ damage; and 105/500 (21%) had more than two organ damage. Acute respiratory distress syndrome was the most prevalent organ damage,153/500 (30.6%); followed by acute cardiac injury, 120/500 (24%); acute kidney injury 107/500 (21.4%); acute liver injury 96/500 (19.2%); septic shock 93/500 (18.6%); disseminated intravascular coagulation 27/500 (5.4%), and heart failure 17/500 (3.4%). We found that in-hospital survival reduced as the number of organs involved increased; only 20% patients survived who had more than 2 organ damage. Also, the chances of survival reduced considerably once other organs were involved in addition to the acute respiratory distress syndrome (91.6% survival in ARDS alone vs. 28.6% survival in ARDS with acute kidney injury vs. 10.4% survival in ARDS with shock/acute cardiac injury/acute kidney injury). Conclusion: Multiple organ dysfunction is common in COVID-19 as 21% had evidence of more than two organ damage in our study. The survival in COVID-19 reduces significantly once multiple organs are involved. Early monitoring and recognition of multiple organ dysfunction is necessary to prevent adverse outcomes and improve survival.

OBJECTIVETraumatic brain injury (TBI) is a major cause of morbidity and mortality. Multiple organ dysfunction syndrome (MODS) occurs frequently after TBI and independently worsens outcome. The present study aimed to identify potential admission characteristics associated with post-TBI MODS.METHODSThe authors performed a secondary analysis of a recent randomized clinical trial studying the effects of erythropoietin and blood transfusion threshold on neurological recovery after TBI. Admission clinical, demographic, laboratory, and imaging parameters were used in a multivariable Cox regression analysis to identify independent risk factors for MODS following TBI, defined as maximum total Sequential Organ Failure Assessment (SOFA) score > 7 within 10 days of TBI.RESULTSTwo hundred patients were initially recruited and 166 were included in the final analysis. Respiratory dysfunction was the most common nonneurological organ system dysfunction, occurring in 62% of the patients. International Mission for Prognosis and Analysis of Clinical Trials (IMPACT) probability of poor outcome at admission was significantly associated with MODS following TBI (odds ratio [OR] 8.88, 95% confidence interval [CI] 1.94–42.68, p < 0.05). However, more commonly used measures of TBI severity, such as the Glasgow Coma Scale, Injury Severity Scale, and Marshall classification, were not associated with post-TBI MODS. In addition, initial plasma concentrations of interleukin (IL)–6, IL-8, and IL-10 were significantly associated with the development of MODS (OR 1.47, 95% CI 1.20–1.80, p < 0.001 for IL-6; OR 1.26, 95% CI 1.01–1.58, p = 0.042 for IL-8; OR 1.77, 95% CI 1.24–2.53, p = 0.002 for IL-10) as well as individual organ dysfunction (SOFA component score ≥ 1). Finally, MODS following TBI was significantly associated with mortality (OR 5.95, 95% CI 2.18–19.14, p = 0.001), and SOFA score was significantly associated with poor outcome at 6 months (Glasgow Outcome Scale score < 4) when analyzed as a continuous variable (OR 1.21, 95% CI 1.06–1.40, p = 0.006).CONCLUSIONSAdmission IMPACT probability of poor outcome and initial plasma concentrations of IL-6, IL-8, and IL-10 were associated with MODS following TBI.

There has been a global outbreak of the coronavirus disease 2019 (COVID-19) since December 2019. Here, we describe the case of a 49-year-old male undergoing maintenance hemodialysis (HD) who got infected with COVID-19 and our experience in performing HD for him. The patient’s symptoms and lung imaging changes were atypical. However, his lymphocyte range decreased upon admission and the polymerase chain reaction of the pharyngeal swab for the ­COVID-19 nucleic acid was positive. The patient developed respiratory failure and required mechanical ventilation 8 days after admission. In the end, he died from multiple organ dysfunction syndrome. The difficulties in diagnosis, infection control, and treatment of COVID-19 in maintenance HD patients are discussed in this report.
