Mit dem Auftreten des SARS-CoV-2 Virus im Jahr 2020 war der Informationsgewinn für vulnerable Patientengruppen essentiell. Ziel dieser Arbeit war es maternale Charakteristika und das klinische Bild SARS-CoV-2 positiver Frauen mit Notwendigkeit einer intensivmedizinischen Behandlung während der Schwangerschaft und postpartal darzustellen, und diese Kohorte mit den SARS-CoV-2 positiven Schwangeren ohne intensivmedizinischen Handlungsbedarf zu vergleichen. Die Daten stammten aus dem deutschen CRONOS-Register, einem prospektiven, multizentrischen Register für SARS-CoV-2 positive schwangere Frauen. Eingeschlossen wurden alle schwangeren und postpartalen Frauen, die während ihrer SARS-CoV-2 Infektion auf eine ITS aufgenommen wurden. Diese wurden hinsichtlich maternaler Charakteristika, Krankheitsverlauf, sowie Outcomes verglichen.
In 101 von 2650 Fällen (4%) der Patientinnen des CRONOS-Registers, kam es zu einer Aufnahme auf die ITS. Als invasivste Form der COVID-19 Behandlung war bei 6 Patientinnen nur eine Überwachung notwendig, 30 Patientinnen benötigten eine Sauerstoffinsufflation, 22 wurden nicht-invasiv beatmet, 28 erhielten eine invasive Beatmung und bei 15 Frauen wurde die Behandlung zur ECMO-Therapie eskaliert. Es wurden keine klinisch signifikanten Unterschiede zwischen Patientinnen gefunden, die unterschiedliche Behandlungsformen benötigten. Die Gruppe der ITS und Non-ITS Patientinnen unterschied sich statistisch signifikant beim Einfluss von Alter, BMI bei Einschluss und der Herkunft. Die Prävalenz der Frühgeburtlichkeit war unter den invasiv behandelten Patientinnen signifikant höher und auch im Vergleich der ITS mit den Non-ITS Patientinnen zeigte sich ein signifikanter Unterschied. Vier Frauen verstarben an COVID-19 und sechs Feten der ITS-Gruppe waren Totgeburten.
Diese Kohorte zeigt, dass schwere COVID-19 Erkrankung bei schwangeren Frauen und Wöchnerinnen selten sind. Die Frühgeburtenrate ist hoch und COVID-19 mit Notwendigkeit einer Atemunterstützung erhöht das Risiko für ein schlechtes maternales und neonatales Outcome. Unter anderem ein höheres Alter und BMI sind mit einem höheren Risiko für eine ITS-Aufnahme verbunden.
Background
Coronavirus disease 2019 (COVID-19) associated coagulopathy (CAC) leads to thromboembolic events in a high number of critically ill COVID-19 patients. However, specific diagnostic or therapeutic algorithms for CAC have not been established. In the current study, we analyzed coagulation abnormalities with point-of-care testing (POCT) and their relation to hemostatic complications in patients suffering from COVID-19 induced Acute Respiratory Distress Syndrome (ARDS). Our hypothesis was that specific diagnostic patterns can be identified in patients with COVID-19 induced ARDS at risk of thromboembolic complications utilizing POCT.
Methods
This is a single-center, retrospective observational study. Longitudinal data from 247 rotational thromboelastometries (Rotem®) and 165 impedance aggregometries (Multiplate®) were analysed in 18 patients consecutively admitted to the ICU with a COVID-19 induced ARDS between March 12th to June 30th, 2020.
Results
Median age was 61 years (IQR: 51–69). Median PaO2/FiO2 on admission was 122 mmHg (IQR: 87–189), indicating moderate to severe ARDS. Any form of hemostatic complication occurred in 78 % of the patients with deep vein/arm thrombosis in 39 %, pulmonary embolism in 22 %, and major bleeding in 17 %. In Rotem® elevated A10 and maximum clot firmness (MCF) indicated higher clot strength. The delta between EXTEM A10 minus FIBTEM A10 (ΔA10) > 30 mm, depicting the sole platelet-part of clot firmness, was associated with a higher risk of thromboembolic events (OD: 3.7; 95 %CI 1.3–10.3; p = 0.02). Multiplate® aggregometry showed hypoactive platelet function. There was no correlation between single Rotem® and Multiplate® parameters at intensive care unit (ICU) admission and thromboembolic or bleeding complications.
Conclusions
Rotem® and Multiplate® results indicate hypercoagulability and hypoactive platelet dysfunction in COVID-19 induced ARDS but were all in all poorly related to hemostatic complications..
(1) Background: Data on coronavirus 2 infection during pregnancy vary. We aimed to describe maternal characteristics and clinical presentation of SARS-CoV-2 positive women requiring intensive care treatment for COVID-19 during pregnancy and postpartum period based on data of a comprehensive German surveillance system in obstetric patients. (2) Methods: Data from COVID-19 Related Obstetric and Neonatal Outcome Study (CRONOS), a prospective multicenter registry for SARS-CoV-2 positive pregnant women, was analyzed with respect to ICU treatment. All women requiring intensive care treatment for COVID-19 were included and compared regarding maternal characteristics, course of disease, as well as maternal and neonatal outcomes. (3) Results: Of 2650 cases in CRONOS, 101 women (4%) had a documented ICU stay. Median maternal age was 33 (IQR, 30–36) years. COVID-19 was diagnosed at a median gestational age of 33 (IQR, 28–35) weeks. As the most invasive form of COVID-19 treatment interventions, patients received either continuous monitoring of vital signs without further treatment requirement (n = 6), insufflation of oxygen (n = 30), non-invasive ventilation (n = 22), invasive ventilation (n = 28), or escalation to extracorporeal membrane oxygenation (n = 15). No significant clinical differences were identified between patients receiving different forms of ventilatory support for COVID-19. Prevalence of preterm delivery was significantly higher in women receiving invasive respiratory treatments. Four women died of COVID-19 and six fetuses were stillborn. (4) Conclusions: Our cohort shows that progression of COVID-19 is rare in pregnant and postpartum women treated in the ICU. Preterm birth rate is high and COVID-19 requiring respiratory support increases the risk of poor maternal and neonatal outcome.
