Abstract

Objectives A high incidence of pulmonary embolism (PE) is reported in patients with critical coronavirus disease 2019 (COVID‐19). Neutrophils may contribute to this through a process referred to as immunothrombosis. The aim of this study was to investigate the occurrence of neutrophil subpopulations in blood preceding the development of COVID‐19 associated PE. Methods We studied COVID‐19 patients admitted to the ICU of our tertiary hospital between 19‐03‐2020 and 17‐05‐2020. Point‐of‐care fully automated flow cytometry was performed prior to ICU admission, measuring the neutrophil activation/maturation markers CD10, CD11b, CD16 and CD62L. Neutrophil receptor expression was compared between patients who did or did not develop PE (as diagnosed on CT angiography) during or after their ICU stay. Results Among 25 eligible ICU patients, 22 subjects were included for analysis, of whom nine developed PE. The median (IQR) time between neutrophil phenotyping and PE occurrence was 9 (7‐12) days. A significant increase in the immune‐suppressive neutrophil phenotype CD16bright/CD62Ldim was observed on the day of ICU admission (P = 0.014) in patients developing PE compared to patients who did not. Conclusion The increase in this neutrophil phenotype indicates that the increased number of CD16bright/CD62Ldim neutrophils might be used as prognostic marker to predict those patients that will develop PE in critical COVID‐19 patients.

Abstract

Additional file 6: Supplementary Figure 5. Effect of CD16/CD62L-antibodies on neutrophil function. Neutrophil phagocytosis (a) and neutrophil phagosomal acidification (b) in five healthy controls after 60 minutes of incubation with S. Aureus bioparticles. Per patient, this analysis was performed three times in different conditions: 1) with 6 μL Hepes buffer, 2) with 6 μL CD16-BV785 and 3) with 6 μL CD62L-BV650. The Hepes buffer and antibody-fluorochrome combinations were added to the wells plate prior to initiation of the functional analyses to prevent a time delay between the different analyses. The Hepes buffer consisted of 20 mM Hepes, 132 mM NaCl, 6 mM KCl, 1.2 mM KH2PO4 and 1 mM MgSO4, supplemented with 5 mM glucose, 1 mM CaCl2, and 0.5% (w/v) human serum albumin. The CD16/CD62L-antibody-fluorochrome combinations were chosen because the fluorochromes are not excited by the 488 laser of the AQUIOS CL® “Load & Go” flow cytometer. A Friedman test was used to compare the three different conditions. No significant differences in neutrophil phagocytosis and neutrophil phagosomal acidification were found after the addition of CD16 and CD62L antibodies. Data are presented as individual values with mean (black line). MFI = median fluorescence intensity. PF520 = PromoFluor 520 LSS. S. Aureus = Staphylococcus Aureus. Ns = non-significant.

Abstract

Additional file 1: Supplementary Figure 1. Gating strategy for the determination of neutrophil phagocytosis and acidification. Granulocytes and lymphocytes can be distinguished on the forward scatter (FS)/side scatter (SS) (a). Neutrophils were identified by selecting granulocytes with CD16 expression (thereby excluding eosinophils) (b). Combined analysis of pHrodo® Green fluorescence and PF520 fluorescence allows for assessment of phagocytosis, expressed as a percentage of PF520-positive neutrophils (c), and neutrophil phagosomal acidification, expressed as the ratio pHrodo® Green fluorescence divided by PF520 fluorescence (d). PF520 = PromoFluor 520 LSS.

Abstract

Additional file 5: Supplementary Figure 4. Effect of temperature changes on neutrophil function. Neutrophil phagocytosis (a) and neutrophil phagosomal acidification (b) in five healthy controls at different temperatures. Blood from 5 healthy controls was analyzed after incubation for 60 minutes with double-labeled bioparticles on ice, in a water bath of 25°C and in a water bath of 37°C. Then, red blood cells were lysed using lysing reagent A and lysing reagent B from the AQUIOS CL® “Load & Go” flow cytometer and leukocyte analysis was performed using the BD FACSCanto™ II (BD Biosciences). Temperature conditions were compared using a Friedman test and a Mann-Whitney U Test with a Dunn's correction for multiple comparisons. Neutrophil phagocytosis and neutrophil acidification significantly differed at different temperatures (p = 0.0008 and p = 0.0394, respectively). Neutrophil phagocytosis increased as the temperature increased, and significant differences were found between samples that were kept on ice and samples that were kept in 37°C (p = 0.005). Such a temperature dependent trend was not observed for neutrophil acidification. However, significant differences were found between 25°C and 37°C (p = 0.034).

Abstract

Additional file 4: Supplementary Figure 3. Neutrophil phagosomal acidification per neutrophil subset. Neutrophil phagosomal acidification of CD16dim/CD62Lbright cells (), CD16bright/CD62Lbright cells () and CD16bright/ CD62Ldim cells () in all patients after 10, 20, 40 and 60 minutes of incubation with S. Aureus bioparticles. Neutrophil phagosomal acidification after 60 minutes was compared between subsets using a one-way ANOVA. Significant differences were found between subsets (p < 0.001). A follow-up comparison of the means was performed with a Tukey’s correction for multiple comparisons. CD16dim/CD62Lbright neutrophils were found to acidify significantly better than CD16bright/CD62Lbright neutrophils (p = 0.016) and then CD16bright/CD62Lbright neutrophils (p < 0.001).

Abstract

The amplitude of the innate immune response reflects the degree of physiological stress imposed by exercise load. An optimal balance of exercise intensity and duration is essential for a balanced immune system and reduces the risk of dysfunction of the immune system. Therefore, it is hypothesized that neutrophils, as key players in the innate immune system, can be used as biomarker in detecting overtraining. The aim was to monitor the state of the innate immune system by phenotyping neutrophils during consecutive bouts of prolonged exercise. Study subjects were recruited from a cohort of walkers participating in a walking event on 3 consecutive days. Participants with immune deficiencies were excluded. Questionnaires to determine the physiological status of the participants were completed. Analysis of neutrophil receptor expression was done by a point‐of‐care fully automated flow cytometer. A total of 45 participants were recruited, of whom 39 participants were included for data analysis. Study participants had a median age of 64 (58‐70) years. The absolute numbers CD16dim/CD62Lbright and CD16bright/CD62Ldim neutrophils were increased after the first 2 days of exercise followed by an adaptation/normalization after the third day. Participants with activated neutrophils (high CD11b expression) had an impaired physical feeling indicated by the participant on a lower visual analog scale compared to participants who did not have activated neutrophils (P = 0.017, P = 0.022). Consecutive days of prolonged exercise results in an initial systemic innate immune response, followed by normalization/adaptation. Increased neutrophil activation was associated with impaired physical feeling measured by a validated VAS score indicated by the participant. Fully automated point‐of‐care flow cytometry analysis of neutrophil phenotypes in a field laboratory might be a useful tool to monitor relevant differences in the systemic innate immune response in response to exercise.
