Benefit of Hemoadsorption Therapy in Patients Suffering Sepsis-Associated Acute Kidney Injury: A Case Series.

INTRODUCTION: Sepsis is defined as life-threatening organ dysfunction in result of the host's dysregulated response to infection and septic shock. Sepsis-associated kidney injury is usually defined as concurrent presence of acute kidney injury (AKI) and sepsis without other significant causative factors. METHOD: The current retrospective study was conducted to elucidate beneficial and side effects of CytoSorb®. A total of 17 patients were primarily treated with continuous renal replacement therapy in combination with CytoSorb. The demand for norepinephrine, mean arterial pressure, lactate, and procalcitonin (PCT) levels, as well as ICU length of stay, was measured. RESULT: The blood lactate levels decreased by 32.30% when comparing mean levels before and after treatment. All patients who survived (n = 14) had reduction in vasopressor demand to 68.96% of their initial dose before the start of treatment. Hospital survival was greater in patients who initially had higher vasopressor demand compared to their nonsurviving counterparts, but in whom vasopressor dosages were reduced significantly during their treatments. Mortality as predicted by APACHE II score in the overall patient population was 79.9%, whereas, the observed ICU mortality was 31%. The baseline PCT levels on patients received 1, 2, and 3 CytoSorbs were 27.08 ± 5.81 ng/mL, 13.28 ± 2.62 ng/mL, and 21.03 ± 6.56 ng/mL, respectively. Observed PCT levels at 24 h after the last treatment on patients received 1, 2, and 3 CytoSorb were 31.55 ± 15.70 ng/mL, 5.61 ± 1.77 ng/mL, and 8.11 ± 3.62 ng/mL, respectively. CONCLUSION: In conclusion, it seems that applying the CytoSorb in combination with CRRT in ICU septic patients with AKI, is related to a significant decrease in mortality, if the integrity and continuity of the treatment be kept, as much as possible. This study presented an effectively positive outcome with cytokine adsorber treatment as an adjuvant along with standard treatment in a high-risk mortality case of septic shock with organ failure.

Blood purification with CytoSorb in critically ill COVID-19 patients: A case series of 26 patients.

Severe forms of the coronavirus disease 2019 (COVID-19) can progress to sepsis-like complications accompanied by "cytokine storm" for which the most effective treatment has not yet been established. Our study describes the results of CytoSorb hemoadsorption in COVID-19 patients treated on the intensive care unit (ICU). In this retrospective study, 26 patients with COVID-19 and acute respiratory distress syndrome (ARDS) were treated with hemoadsorption therapy. Pre-, and post-treatment values (clinical and laboratory) were compared. Data are expressed as mean (confidence intervals, CI), or median [interquartile ranges, IQR], as appropriate. Patients received 2 hemoadsorption treatments. This resulted in a significant decrease in norepinephrine requirements, and inflammatory marker plasma concentrations (procalcitonin, C-reactive protein, ferritin) when comparing pre versus post treatment levels. The PaO2 /FiO2 and overall organ function (ie, Sequential Organ Failure Assessment-SOFA score) also improved significantly. Patients stayed on the ICU for 9 days and 21 of them survived. To the best of our knowledge, this is one of the largest case series to date reporting early experiences on extracorporeal hemoadsorption therapy in SARS-CoV-2 positive patients with hyperinflammation and moderate ARDS. Treatment proved to be effective, technically feasible and well-tolerated.

Effects of Morphine and Fentanyl on Patients with COVID-19.

BACKGROUND: Sustained inflammation has been observed in the majority of severe COVID-19 cases. The impact of choice of opioid on perioperative inflammatory processes has not been assessed in the clinical setting. MATERIALS AND METHODS: Patients with novel coronavirus (COVID-19) who referred to Masih Daneshvari and Noor-Afshar Hospitals in Tehran were included in the study after providing full explanations and obtaining written consent. Patients were then randomly divided into three groups: morphine, fentanyl and control. Patients in the morphine group received 3 mg of morphine intravenously every 6 hours for 5 days, whereas in the fentanyl group, 1.5 mcg / kg / h of fentanyl was infused for 2 hours on 5 consecutive days. The results were evaluated based on the design of the questionnaire and its completion using t-test and SPSS25 software. RESULTS: A total of 127 participants responded to the survey between 20 April and 20 June 2020, of whom 90 (70.86%) with the average age 65.2 years, provided complete data on variables included in the present analyses. 53 (58.33%) of all individuals were men and 37 (41.12%) were women. Accordingly, 22 (24.4%) patients had a history of hypertension. However, diabetes with 16 (17.77%) cases and kidney diseases with 12 (13.33%), were the next most common underlying diseases. Evaluation of patients' clinical, laboratory and inflammatory conditions at different time intervals in both fentanyl and morphine groups did not show significant changes between these groups and the patients in the control one. CONCLUSION: The results of this study did not show any significant change in the use of fentanyl and morphine compared to patients with COVID 19. This may be due to the use of these drugs in the viral phase of the disease. The use of morphine and fentanyl in the viral phase of COVID 19 disease do not show significant benefits.

Invasive candidiasis in critical care setting, updated recommendations from "Invasive Fungal Infections-Clinical Forum", Iran.

Invasive candidiasis (IC) bears a high risk of morbidity and mortality in the intensive care units (ICU). With the current advances in critical care and the use of wide-spectrum antibiotics, invasive fungal infections (IFIs) and IC in particular, have turned into a growing concern in the ICU. Further to blood cultures, some auxiliary laboratory tests and biomarkers are developed to enable an earlier detection of infection, however these test are neither consistently available nor validated in our setting. On the other hand, patients' clinical status and local epidemiology data may justify the empiric antifungal approach using the proper antifungal option. The clinical approach to the management of IC in febrile, non-neutropenic critically ill patients has been defined in available international guidelines; nevertheless such recommendations need to be customized when applied to our local practice. Over the past three years, Iranian experts from intensive care and infectious diseases disciplines have tried to draw a consensus on the management of IFI with a particular focus on IC in the ICU. The established IFI-clinical forum (IFI-CF), comprising the scientific leaders in the field, has recently come up with and updated recommendation on the same (June 2014). The purpose of this review is to put together literature insights and Iranian experts' opinion at the IFI-CF, to propose an updated practical overview on recommended approaches for the management of IC in the ICU.

Soluble triggering receptor expressed on myeloid cells 1 and the diagnosis of sepsis.

PURPOSE: Early diagnosis and assessment of the systemic inflammatory response to infection are difficult with usual markers (fever, leukocytosis, C-reactive protein [CRP]). Triggering receptor expressed on myeloid cells-1 (TREM-1) expression on phagocytes is up-regulated by microbial products. We studied the ability of soluble TREM-1 (sTREM-1) to identify patients with sepsis. MATERIALS AND METHODS: Plasma samples were obtained on intensive care unit admission from patients with systemic inflammatory response syndrome for sTREM-1 measurement. RESULTS: Soluble TREM-1, CRP concentrations and erythrocyte sedimentation rate (ESR) were higher in the sepsis group (n = 52) than in the non-infectious systemic inflammatory response syndrome group (n = 43; P = .00, .02, and .001, respectively). Soluble TREM-1, CRP concentrations, white blood cell count and ESR were higher in the sepsis group than in the non SIRS group (n = 37; P = .04, .00, .01, and .00, respectively). In a receiver-operating characteristic curve analysis, ESR, CRP and sTREM-1 had an area under the curve larger than 0.65 (P = .00), in distinguishing between septic and non-infectious SIRS patients. CRP, ESR, sTREM-1 had a sensitivity of 60%, 70% and 70% and a specificity of 60%, 69% and, 60% respectively in diagnosing infection in SIRS. CONCLUSION: C-reactive protein and ESR performed better than sTREM-1 and white blood cell count in diagnosing infection.
