RESUMO

Összefoglaló. Bevezetés: A SARS-CoV-2 koronavírus okozta COVID-19 általános egészségügyi és gazdasági krízist idézett elo. Célkituzés: A megfigyeléses vizsgálat célja a BNT162b2 mRNS-Pfizer-BioNTech-vakcina hatásosságának, biztonságosságának és immunogenitásának igazolása a Budai Irgalmasrendi Kórház dolgozóin. Módszer: A vakcina adása után elemeztük a COVID-19-fertozés elofordulását, az oltások utáni reakciókat, valamint a "spike" (S-) protein és a nukleokapszid (N)-protein elleni ellenanyag szintjének változását. Eredmények: A felmérésben részt vevo 295 dolgozó közül az oltást megelozoen 36 dolgozó esett át COVID-19-fertozésen (COVID-19-pozitív csoport). A második oltás után a megfigyelési idoszak három hónapjában COVID-19-fertozés nem alakult ki a felmérésben részt vevo oltott dolgozók körében. Az oltási reakciók enyhék voltak. A COVID-19-pozitív csoportban az N-antitestek medián küszöbértékindexe az elso vakcina után 4 héttel mérve szignifikánsan magasabb volt (28,37), mint a COVID-19-negatív (0,085) csoportban (p<0,0001). Az elso vakcina után 4 héttel az S-antitestek medián értéke (8015 U/ml) a COVID-19-pozitív csoportban szignifikánsan magasabb volt (p<0,0001), mint a COVID-19-negatív csoportban (23,18 U/ml). A COVID-19-negatív csoport S-antitest-középértéke a második vakcina után szignifikáns (p<0,0001), mintegy 500×-os emelkedést mutatott (23,18 U/ml rol 1173 U/ml-re). Egy vakcina hatásosságát a fertozések terjedésének megakadályozása igazolja. Következtetések: A második vakcina utáni megfigyelési idoszakban új COVID-19-fertozés nem volt az oltott dolgozók körében. A fertozésen át nem esett COVID-19-negatív egyének esetén az S-antitest emelkedése mérsékelt az elso oltás után, míg a második oltás után lényegesen emelkedik. A COVID-19-fertozésen átesett egyének csoportjában már az elso vakcina is jelentos S-antitest-termelodést vált ki. Orv Hetil. 2021; 162(39): 1551-1557. INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic caused global public health and economic crises. OBJECTIVE: The aim of this observation study was to estimate the effectiveness, safety and elicited immune response of the BNT162b2 mRNA Pfizer-BioNTech vaccine in healthcare workers of the Buda Hospital of the Hospitaller Order of St. John of God. METHOD: After vaccination, the infection rate, adverse events and the kinetics of anti-SARS-CoV-2 spike (S) protein and anti-SARS-CoV-2 nucleocapsid (N) protein antibodies were evaluated. RESULTS: Before vaccination, from the 295 healthcare workers 36 recovered from prior COVID-19 infection (COVID-19-positive group). After the second vaccination, there was no COVID-19 infection during the three-month follow-up period. The adverse events were mild. In the COVID-19-positive group, the median cut-off index of anti-N antibodies measured at 4 weeks after the first vaccination were significantly (p<0.0001) higher (28.37) than in the COVID-19-negative group (0.085). After the first vaccine, the median titer of anti-S antibodies was significantly higher (p<0.0001) in the COVID-19-positive group (8015 U/ml) compared to the COVID-19-negative group (23.18 U/ml). In the COVID-19-negative group, the median titer of anti-S antibodies increased significantly (p<0.0001) after the second vaccine (from 23.18 U/ml to 1173 U/ml), showing an increase of 500×. CONCLUSIONS: After the second vaccination, there was no COVID-19 infection during the follow-up. In the COVID-19-negative group, the anti-S antibody titer is moderate after the first vaccination and increases significantly after the second vaccine. In the COVID-19-positive group, the first vaccine induces significant anti-S antibody production. Orv Hetil. 2021; 162(39): 1551-1557.

RESUMO

BACKGROUND: Ventilatory inefficiency (high volume of expired air/volume of carbon dioxide eliminated [Ve/Vco2] slope), and impaired exercise tolerance (low peak volume of oxygen consumption) obtained from cardiopulmonary exercise testing (CPX) strongly predict mortality in heart failure (HF) patients; however, other CPX variables may also contain prognostic information. Therefore, the purpose of this study was to determine the prognostic power of the aggregate of CPX data. METHODS: The study prospectively monitored 390 patients referred for cardiac transplantation evaluation for 10 years for events (death, urgent transplant, left ventricular assist devices). Cox regression was used to analyze 18 CPX variables to identify the best survival model. RESULTS: Ve/Vco2 slope was the most powerful mortality predictor, and only resting systolic blood pressure (SBP) added additional independent prognostic power when expressed at its threshold effect value as SBP ≤ 100 mm Hg. Patients with low SBP had a greater risk than those who were within the next higher quartile of Ve/Vco2 slope with SBP > 100 mm Hg. A very high-risk cohort included 9% of the population that had a Ve/Vco2 slope > 41 and SBP ≤ 100 mm Hg and an associated 2-year event rate of 67%; conversely, a low-risk cohort had a Ve/Vco2 slope ≤ 30 and SBP >100 mm Hg and associated 2-, 5-, and 10-year event rates of 5%, 12%, and 30%, respectively. CONCLUSIONS: Ve/Vco2 slope was the best individual predictive CPX variable and its interpretation was significantly altered by the presence of hypotension. An algorithm combining these CPX variables identifies a HF population at very high risk of early death and warranting advanced therapies.
