Megjegyzések:Objectives Angiotensin-converting enzyme 2 (ACE2) represents the primary receptor for SARS-CoV-2 to enter endothelial cells. Here we investigated circulating ACE2 activity to predict the severity and mortality of COVID-19. Methods Serum ACE2 activity was measured in COVID-19 (110 critically ill and 66 severely ill subjects at hospital admission and 106 follow-up samples) and in 32 non-COVID-19 severe sepsis patients. Associations between ACE2, inflammation-dependent biomarkers, pre-existing comorbidities, and clinical outcomes were studied. Results Initial ACE2 activity was significantly higher in critically ill COVID-19 patients (54.4 [36.7-90.8] mU/L) than in severe COVID-19 (34.5 [25.2-48.7] mU/L; P<0.0001) and non-COVID-19 sepsis patients (40.9 [21.4-65.7] mU/L; P=0.0260) regardless of comorbidities. Circulating ACE2 activity correlated with inflammatory biomarkers and was further elevated during the hospital stay in critically ill patients. Based on ROC-curve analysis and logistic regression test, baseline ACE2 independently indicated the severity of COVID-19 with an AUC value of 0.701 (95% CI [0.621-0.781], P<0.0001). Furthermore, non-survivors showed higher serum ACE2 activity vs. survivors at hospital admission (P<0.0001). Finally, high ACE2 activity (?45.4 mU/L) predicted a higher risk (65 vs. 37%) for 30-day mortality (Log-Rank P<0.0001). Conclusions Serum ACE2 activity correlates with COVID-19 severity and predicts mortality.

Cím:A dramatic rise in serum ACE2 activity in a critically ill COVID-19 patient / Nagy Béla, Fejes Zsolt, Szentkereszty Zoltán, Sütő Renáta, Várkonyi István, Ajzner Éva, Kappelmayer János, Papp Zoltán, Tóth Attila, Fagyas Miklós

Megjegyzések:Endothelial cells express surface angiotensin-converting enzyme 2 (ACE2), the main receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that promotes the infection of endothelial cells showing activation and damage. Bronchoalveolar lavage fluid from coronavirus disease-2019 (COVID-19) subjects showed a critical imbalance in the renin-angiotensin-aldosterone system with the upregulated expression of ACE2. Recently, intravenous recombinant ACE2 was reported as an effective therapy in severe COVID-19 by blocking the viral entry to target cells. Here, we present a case of a critically ill COVID-19 patient with acute respiratory distress syndrome where circulating ACE2 was first measured to monitor disease prognosis. ACE2 activity increased about 40-fold over the normal range and showed a distinct time course as compared to 2-3-fold higher levels of endothelium biomarkers. Although the level of soluble E-selectin followed the clinical status of our patient similar to ferritin and IL-6 levels, the dramatic rise in serum ACE2 activity may act as an endogenous nonspecific protective mechanism against SARS-CoV-2 infection that preceded the recovery of our patient.

Megjegyzések:Objectives: Elderly patients with hematologic malignancies face the highest risk of severe COVID-19 outcomes. The infection's impact on different age groups remains unstudied in detail. Methods: We analyzed elderly patients (age groups: 65-70, 71-75, 76-80, and >80 years old) with hematologic malignancies included in the EPICOVIDEHA registry between January 2020 and July 2022. Univariable and multivariable Cox regression models were conducted to identify factors influencing death in COVID-19 patients with hematological malignancy. Results: The study included data from 3,603 elderly patients (aged 65 or older) with hematological malignancy, with a majority being male (58.1%) and a significant proportion having comorbidities. The patients were divided into four age groups, and the analysis assessed COVID-19 outcomes, vaccination status, and other variables in relation to age and pandemic waves. The 90-day survival rate for patients with COVID-19 was 71.2%, with significant differences between groups. The pandemic waves had varying impacts, with the first wave affecting patients over 80 years old, the second being more severe in 65-70, and the third being the least severe in all age groups. Factors contributing to 90-day mortality included age, comorbidities, lymphopenia, active malignancy, acute leukemia, less than three vaccine doses, severe COVID-19, and using only corticosteroids as treatment. Conclusion: These data underscore the heterogeneity of elderly hematological patients, highlight the different impacts of COVID-19 waves and the pivotal importance of vaccination, and may help in planning future healthcare efforts. ? 2023 The Author(s)

Cím:Index of Stimulation and TNFα Measurements Used for laboratory Diagnosis of Latent Tuberculosis as a New Principle / Sipka Sándor, Papp Zsuzsánna, Kovács Ildikó, Horváti Kata, Bősze Szilvia, Hudecz Ferenc, Szilasi Mária
Dátum:2018
Megjegyzések:A new principle of a method for the laboratory diagnosis of latent Mycobacterium tuberculosis infection (LBTI) compared to the QuantiFERON (QFT) test is presented. The new elements, the calculation and introduction of an Index of Stimulation (IS) were based on the measurements of tumour necrosis-? (TNF-?) release in whole human blood stimulated by the peptides (TB-P) derived from Mycobacterium tuberculosis (Mtb) related proteins and Purified Protein Derivative (PPD). The amount of TNF-? was determined by ELISA. The calculation of IS values was carried by the formula: TNF?(pg/ml)TB-P/ TNF-?(pg/ml)PPD. The populations studied consisted of a) 15 healthcare workers dealing with Mtb- infected patients (HCWTB); b) 14 healthcare workers not being exposed to Mtb patients (HCW-C) as controls. The diagnosis of LTBI was established if IS was higher than 1.50. In the HCW-TB group the number of LTBI was 6/15 by the new method and 9/15 by QFT. Tested clinically, the number of false-positive results by QFT was 3/9. All members of HCW-C group were LTBI negative by both methods. This new assay did not result in any false positive reactions. Although these results are still preliminary data derived from few patients. However, the theoretical novelties in the principle of method: the calculation of IS from the TNF-?-TB-P/ TNF-? ?PPD values can mean a progress in the individual laboratory diagnosis of LTBI in further studies.
