SESSION TITLE: Biological Markers in Patients with COVID-19 Abstract PostersSESSION TYPE: Original Investigation PostersPRESENTED ON: 10/18/2022 01:30 pm - 02:30 pmPURPOSE: Severe COVID19 patients present with low CD8(+) T cell counts. A reduced number of T-cells seems to be correlated with high serum IL-6 and IL-10 levels, and a marked inflammatory state. This study aimed to assess if low CD8(+) counts were associated with inflammation markers, length of stay, and Ichikado CT scores in COVID-19 patients.METHODS: A retrospective study of adult patients admitted to our hospital with COVID-19 infection from June 2021 to September 2021. CD8(+) count was obtained, and patients were divided into less than 150 cells/μl and more than 150 cells/μl. Ferritin, c-reactive protein (CRP), erythrocyte sedimentation rate (ESR), troponin, Lactate dehydrogenase (LDH), and d-Dimer values were also recorded. Primary outcomes were hospital length of stay (LOS), Ichikado CT score, and correlation of CD8(+) count and inflammatory markers. Descriptive statistics, and Mann-Whitney-U methods were utilized.RESULTS: 264 patients were included, median age was 50 years [41-61]. 143 (54.2%) patients were male. There was a statistically significant difference when assessing hospital LOS in patients with CD8(+) counts <150 cells/μl vs > 150 cells/μl (9 days [5-16] vs 5 days [4-9], U=(134, 84)=3742, z=-4.174, p<0.01). The Ichikado CT score was significantly different between groups (190 [150-220] vs [130-190], U=(128,80)=3394, z=-4.094, p<0.01). IL-6 and IL-10 values were higher in those patients with CD8(+) less than 150 μl, when compared to higher CD8(+) counts. IL-10 value was (23.8pg/ml [13.6-43.3] vs (6.6pg/ml [9.4-29.2]), U=(131,78)=3711.5, z=-3.305, p<0.01), and for IL-6 (23.8pg/ml [7.6-88.3] vs (11.9 [4.1-32.1]), U=(125,75)=3473.5, z=-3.064, P<0.01). Ferritin was increased in patients with CD8(+) counts lower than 150 cells/μl compared to more than 150 cells/μl (845.3ng/ml [381.6-1600] vs 480ng/ml [232.6-988.7], U=(133,83)=3939.5, z=-3.550, p=<0.01). Similarly, CRP (83mg/L [46.3-136.7] vs 60.2 mg/L [33.25-100.72], U=(134-82)=4208, z=-2.885, p=<0.01), d-Dimer (1.76mg/L [0.53-7] vs 0.64 mg/L [0.35-1.72], U= (134,84)=3635.5, z=-4.396, p<0.01), and LDH (555IU/L [361-849.2] vs 375.5IU/L [273.2-531.2], U=(122,72)=2740,z=-4.373,p<0.01). Troponin and ESR were not significantly different, median troponin (0.022ng/ml [0.011-0.039] vs 0.012ng/ml [0.007-0.032], U=(111,70)=3218, z=-1.944,P=0.052) and median ESR (78mm/hr [57.2-105] vs 76.5 mm/hr [55-108.7], U=(134,84)=5603, z=-0.055,P=0.95).CONCLUSIONS: CD8(+) counts below 150 cells/μl are associated with increased inflammatory markers, a longer hospital stay, and higher Ichikado CT scores.CLINICAL IMPLICATIONS: CD8(+) count below 150 cells/μl is other indicator of disease severity in COVID-19DISCLOSURES: No relevant relationships by David AkinwaleNo relevant relationships by Angelica AlmaguerNo relevant relationships by Sushen BhallaNo relevant relationships by Ailine Canete CruzNo relevant relationships by Ndiya EmeabaSpeaker/Speaker's relationship with johnson and johnson Please note: approx year 2000 Added 03/31/2022 by Joseph Gathe, value=Honorariaclinical research relationship with gilead Please note: since 1990 Added 03/31/2022 by Joseph Gathe, value=Grant/Researchclinical research relationship with ansun Please note: 2020 Added 03/31/2022 by Joseph Gathe, value=Grant/Research Supportclinical research relationship with regeneron Please note: 2020 Added 03/31/2022 by Joseph Gathe, value=Grant/Research SupportNo relevant relationships by Jesus Salvador Gonzalez LopezNo relevant relationships by Najia HussainiNo relevant relationships by Claudia RamirezNo relevant relationships by Salim SuraniNo relevant relationships by Daryelle VaronNo relevant relationships by Joseph VaronNo relevant relationships by Mohamed Ziad SESSION TITLE: Biological Markers in Patients with COVID-19 Abstract Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/18/2022 01:30 pm - 02:30 pm PURPOSE: Severe COVID19 patients present with low CD8(+) T cell counts.
