RESUMO
Background: Septic shock, defined as organ dysfunction caused by a dysregulated host response to infection, is a condition associated with high morbidity and mortality. One of the hallmarks of sepsis is the excessive release of cytokines and other inflammatory mediators that cause septic shock and multi-organ failure (MOF). New adsorbents are now available as adjuvant therapy aimed at modulating the cytokine "storm" in sepsis. They are thought to be useful if adopted early (within 8-24 hours of the diagnosis of septic shock) in patients who are unresponsive to standard therapy. Here we report our experience with CytoSorb. Method(s): From January 2021 to May 2022, 46 patients with septic shock were treated with continuous renal replacement therapy (CRRT) associated with hemoadsorption with CytoSorb. All cases presented organ failure including AKI. Surgical patients (n = 13) were treated with surgery, COVID patients (n = 15) and medical patients (n = 16) with medical therapy;all surgery cases were operated on before starting the haemadsorption and in some cases reoperation with the need to suspend the adsorption. The mean age was 69 +/- 17 years (SD). On admission the mean SAPSII score was 50 +/- 11 (SD). CRRT as hemodiafiltration (CVVHDF) was performed. All patients received at least one CytoSorb treatment and additional treatments (up to 21 filters in a Covid patient) according to our indication. The CytoSorb cartridge was installed in series to the high cut-off filter;blood flow rates were maintained between 120 and 150 mL/min while dialysis doses from 18 to 45 mL/kg/hour. CytoSorb was renewed every 24 hours. We evaluated the impact of CytoSorb on 30-day survival, haemodynamics and relevant outcomes. Result(s): The 30-day survival was 30%. During treatment with CytoSorb, patients had a hemodynamic stabilization with a significant improvement in MAP, a reduction in amines and a decrease in PCR and PCT (Figure 1). Mortality at 30 days among medical patients was almost comparable to that of COVID patients and higher than that of surgical patients (70%, 69% and 61%, respectively). It should be noted that almost half of the deceased patients arrived late in the hospital, thus leading to a late start of treatment. Conclusion(s): We confirm the efficacy and usefulness of the CytoSorb if adopted early in patients who do not respond to standard therapy. CytoSorb treatment was safe and well tolerated with no device-related adverse events during or after treatment sessions.
RESUMO
Patients on chronic dialysis have an increased risk for SARS CoV-2 virus disease and its complications because of multiple comorbidities and alterations in the immune response caused by renal disease. In this retrospective observational study we describe the clinical features and the evolution of SARS CoV-2-related disease in 19 patients of our Pesaro and Fano facilities, where incidence and mortality of the epidemic were among the highest in Italy. A total of 176 patients were undergoing chronic treatment, 153 hemodialysis and 23 peritoneal dialysis. The incidence of infection was 10,8%, with 84% needing hospitalization and mortality amounting to 53%. The most frequent onset symptom was fever (84,2%) and the most used therapy was an association of low molecular weight heparin and hydroxychloroquine (57,9%). Comparing the deceased and survivor populations we noticed significant differences in age and presence of cardiopathy for what concerns anamnestic data and in fatigue and dyspnea in terms of clinical presentation. LDH and CPK resulted highest among deceased patients, while the use of enoxaparin was more frequent in survivors. By observing contagions over time, we also noticed that most of the cases, and the ones with worse clinical condition and outcome, all occurred in the early stage of the epidemic and in particular within the first 20 days from the implementation and codification of the measures to prevent its spread, the only modifiable factor that had an unmistakable effect on the evolution of events.
RESUMO
OBJECTIVE: The Coronavirus Disease 2019 (COVID-19) pandemic mainly involves respiratory symptoms, though gastrointestinal (GI) symptoms are increasingly being recognized. In this context, the presence of comorbidities appears to be associated with adverse outcomes. However, the role of digestive manifestations is not yet well defined. The primary aim of this study was to assess the prevalence of GI symptoms and digestive comorbidities in a cohort of patients with COVID-19 compared to controls. The secondary aim was to determine the association of GI-symptoms and digestive comorbidities with clinical outcomes. PATIENTS AND METHODS: Inpatients with COVID-19 and controls with similar symptoms and/or radiological findings were enrolled. Symptoms at admission and throughout hospitalization were collected as they were comorbidities. The measured clinical outcomes were mortality, intensive care unit admission and cumulative endpoint. RESULTS: A total of 105 patients were included: 34 with COVID-19 and 71 controls. At admission, the prevalence of GI symptoms among COVID-19 patients was 8.8%. During hospitalization, the frequency of GI symptoms was higher in patients with COVID-19 than in controls (p=0.004). Among patients with COVID-19, the mortality and a cumulative endpoint rates of those with GI symptoms were both lower than for those without GI symptoms (p=0.016 and p=0.000, respectively). Finally, we found digestive comorbidities to be associated with a milder course of COVID-19 (p=0.039 for cumulative endpoint). CONCLUSIONS: Our results highlighted the non-negligible frequency of GI symptoms in patients with COVID-19, partly attributable to the therapies implemented. In addition, the presence of GI symptoms and digestive comorbidities is associated with better outcomes. Most likely, digestive comorbidities do not hinder the host's immune response against SARS-COV-2, and the occurrence of GI symptoms might be linked to a faster reduction of the viral load via the faecal route.
