ABSTRACT

Introduction: Coronavirus disease 2019 (COVID-19) has been associated with high in-hospital mortality. Since the implementation of guidelines and improvement in the quality of cardiopulmonary resuscitation (CPR), the survival rate for non-COVID-19 patients has improved. There is, however, scarce data regarding in-hospital cardiac arrest outcomes in COVID-19 patients. This study aimed to investigate cardiac arrest outcomes in patients hospitalized for COVID-19. Method(s): Retrospective study of the data of 994 adult patients admitted to a single-center high acuity critical care COVID-19 unit between March 2020 and February 2022 with COVID-19 diagnosis. Patients who underwent CPR were identified. Resuscitation registers and demographic information were obtained. The primary outcome was survival to hospital discharge. Secondary assessments were the initial rhythm and duration of CPR. Descriptive statistics were utilized. Result(s): A total of 994 COVID-19 patients were included in the study. 129 (13%) had a cardiac arrest and underwent CPR. Two patients survived hospital discharge (1.6%). Of them, 91(70.5%) were male. Mean age was 68.6 (+/-13.5) years. Median BMI was 29.1 [25.8-35.7] Kg/m2. The most frequent comorbidity was hypertension in 59 patients (46.1%), followed by diabetes type 2 in 30 patients (23.4%), and there were 37 (28.9%) patients with no comorbidities. The median time from admission to cardiac arrest was 12[6-18.5] days, the most common rhythm at the time of cardiac arrest was asystole in 94 (72.9%) patients, followed by pulseless electrical activity in 25 (19.4%);Ventricular dysrhythmias occurred in 7 (5.5%)of the cases. Finally, the median duration of CPR was 20[13.7-29] minutes. Conclusion(s): Survival of COVID-19 patients after in-hospital cardiac arrest was dismal, despite the adequate implementation of resuscitation protocols. Many of these patients were overweight or obese with comorbid conditions. The most common presenting rhythm was a non-shockable rhythm.

ABSTRACT

INTRODUCTION: Increased mortality due to COVID-19 in the intensive care unit (ICU) raised questions about the best way and time to use invasive mechanical ventilation (IMV). The purpose of this study is to analyze effectiveness of IMV in COVID-19 patients. METHOD(S): We performed a retrospective analysis of adult patients admitted to our hospital with COVID-19 infection from May 2020 to December 2021. We reviewed the need of IMV in patients admitted to the ICU with APACHE II scores higher than 12.5. Outcomes from the IMV-receiving patients were compared to outcomes from patients on non-invasive mechanical ventilation (NIMV). The second analysis of IMV aimed to determine the best initiation time for IMV. Patients were divided into Group1: early intubation (IMV within the first 24hrs of admission) and Group2: late intubation (IMV later than 24hrs after admission). Primary outcomes included mortality and length of stay (LOS) in the ICU. Descriptive statistics, Mann-Whitney-U and Chi-square methods were used. RESULT(S): For the first part of the analysis, 82 patients were included. They were divided into 2 groups (IMV and NIMV) of 41 patients each. Median age in IMV group was 67 [51.5- 75.5] vs 64 [47.5-73.5]. 21 (51.2%) patients died in the IMV group vs 22 (53.7%) X2(1, N=82)=0.049, p=0.5. Median LOS in the IMV group was 10 [6-16] days vs 11 [5-19.5] days U(NIMV group=41, NNIMV group=41)=819, z=-0.2, p=0.84. For the second analysis, 68 patients were included. They were divided into 2 groups (Group1 and 2) of 34 patients each. Median age in group1 was 53.5 [25-90] vs 53.5 [37.75-65.25]. 19 (55.9%) patients in group1 were male vs. 26 (76.5%). The median APACHE II, SOFA and ICHIKADO scores on admission in group1 were 8 [6-10.5], 1.5 [1-2], 120 [110-165] points respectively vs 9.5 [6-16.5], 2 [1-4], 150 [132.5-200] points. 3 (8.8%) patients died in group1 vs 11 (32.4%) X2(1, N=68)=5.76,p=0.033. Median LOS in group1 was 4.5 [3-8.5] days vs 6 [3.75-10.5] days U(NGroup1=34, NGroup2=34)=450, z=-1.59, p=0.113. CONCLUSION(S): In COVID-19 patients admitted to the ICU with APACHE II score higher than 12.5, mortality and LOS were not significantly different in patients that received IMV vs those that received NIMV. Early intubation correlated with improved mortality, but not with length of ICU stay.

ABSTRACT

INTRODUCTION: The antiviral efficacy of remdesivir is still controversial. We aimed to evaluate the impact of remdesivir use in patients admitted to our intensive care unit (ICU) with COVID-19. METHOD(S): A retrospective study of adult patients admitted to our hospital with COVID-19 infection from March 2020 to September 2021 was performed. Patients were divided into 2 groups;Group1 received remdesivir while Group2 did not. The primary outcomes studied were mortality rate, length of stay (LOS) in the ICU and the need of invasive mechanical ventilation (IMV). Additional outcomes assessed were highest APACHE II during stay and inflammatory markers (Ferritin, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)). Descriptive statistics, Mann-Whitney-U and Chisquare methods were used. RESULT(S): 227 patients were included, median age was 57 years [46-68]. 122 (53.7%) were male. 113 patients were in Group1 vs 114 in Group2. Median age in Group1 is 58 years [45.75-68] vs 57 years [46.5-68] in Group2. In Group1, 64 (56.1%) were male vs 58 (51.3%). The median APACHE II score on admission for group1 was 8 [5-12] vs 9 [6-12]. The median SOFA score on admission for group1 was 2 [2-3] vs 2 [1-2.75]. The median ICHIKADO score on admission for group1 was 160 [120-200] vs 140 [110-180]. 24 (21.1%) patients died in group1 vs 21 (18.6%) in group2 x2(1, 227) = 0.218, p = 0.74. The median LOS of group1 was 7 [4-10] vs 7 [5-11] U(NGroup1=114, NGroup2=113)=6400, z=- 0.083, p=0.934. 16 (14%) patients in group1 needed IMV vs 22 (19.5%) in group 2, x2(1, 227) = 0.273, p = 0.291. The median of the highest APACHE II score in group1 was 10 [6- 17.5] vs 11 [7-15] U(NGroup1=114, NGroup2=112)=6163, z=-0.45, p=0.652. In group1, median ferritin, CRP and ESR were 486.6 [246.75-1184.5] ng/ml, 90.35 [39.48-135] mg/L, 85 [60-106.5] mm/hr, respectively vs. 493.3 [174.6- 1025.5] ng/ml, 69.6 [35.25-116.75] mg/L, 77 [47.5-110] mm/hr, U(NGroup1=114, NGroup2=107)=5614.5, z=- 1.022, p=0.307, U(NGroup1=56, NGroup2=34)=854, z=- 0.816, p=0.415, U(NGroup1=113, NGroup2=110)=5644.5, z=-1.185, p=0.236, respectively. CONCLUSION(S): There is no difference in mortality, severity scales nor inflammatory markers in patients that were treated with remdesivir compared to those who were not.

ABSTRACT

INTRODUCTION: Thrombocytopenia (TCP) can be caused by Epstein-Barr Virus (EBV), Cytomegalovirus (CMV), and Coronavirus Disease 2019 (COVID-19). This study aimed to evaluate the degree of TCP in COVID-19 patients with coinfection with EBV and/or CMV. METHOD(S): Retrospective study of adult patients admitted to our hospital with COVID-19 infection from March 2020 to February 2022 was conducted. Patients were divided into two groups. Group 1 (G1) had viral co-infection with EBV and/or CMV and group (G2) did not. These groups were analyzed based on the degree of TCP. Thrombocytopenia was classified into mild (100-150x103/uL), moderate (50- 99x103/uL), and severe (< 50x103/uL). Primary outcomes were mortality, need for ventilation (NFV), and length of stay (LOS). Descriptive statistics, crosstabulation, Chi-square, and Mann-Whitney tests were used. RESULT(S): Of 994 patients, 445 with a median age of 57 [45-68] years were tested for viral co-infection. 262 (58.9%) were male and 327 (73.5%) survived. There was a statistically significant association between co-infection and TCP, X2(3)= 22.335, p= <.001. Of 218 patients in G1, 98 (45.0%) had normal platelet count (NPC), 44 (20.2%) had mild TCP, 47 (21.6%) had moderate, and 29 (13.3%) had severe. Of 227 patients in G2, 132 (58.1%) had NPC, 59 (26.0%) had mild TCP, 26 (11.5%) had moderate, and 10 (4.4%) had severe. There was a statistically significant association between coinfection and mortality, X2(1)= 36.682, p= <.001. In G1, 86 (39.4%) died and 132 (60.6%) survived. In G2, 32 (14.1%) died and 195 (85.9%) survived. There was a significant difference in LOS between the groups, [U= 16935.50, p= <.001]. G1 had a median LOS of 12 [6-19] days and G2 had a median of 7 [4-11] days. There was no statistically significant association between co-infection and NFV, X2(1)= .033, p= .856. In G1, 34 (15.6%) patients were mechanically ventilated and 184 (84.4%) were not. In G2, 34 (15.0%) were ventilated and 193 (85.0%) were not. CONCLUSION(S): COVID-19 and viral co-infection with EBV and/or CMV is associated with the presence of thrombocytopenia, mortality, and longer LOS in hospitalized patients. The presence of co-infection is associated with moderate and severe TCP.

ABSTRACT

INTRODUCTION: Weight-related health problems typically arise in those with a BMI higher than 30. This study aimed to evaluate the effect of BMI on COVID-19 outcomes. METHOD(S): Retrospective cohort study was conducted on patients in our hospital with COVID-19 from March 2020 to February 2022. Admission BMI was categorized into six classifications: underweight (< 18.5 kg/m2), normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), obese class 1 (30-34.9 kg/m2), obese class 2 (35-39.9 kg/m2), and obese class 3 (>40 kg/m2). Primary outcomes were mortality, days hospitalized, and need for mechanical ventilation. Descriptive statistics, Chi-square, and Kruskal-Wallis tests were performed. RESULT(S): 986 individuals were included with a median age of 56 years [45-67]. Overall median BMI was 29.3 kg/m2 [27- 34.5 kg/m2]. 554 (56.2%) patients were males. Median BMI for females was 30.3 kg/m2 [26.4-35.4 kg/m2], and for males was 29.1 kg/m2 [25.8-33.9 kg/m2]). A total of 799 (81%) survived. Survival in underweight patients was 13 (86.7%), normal weight was 143 (81.7%), overweight was 267 (79%), obese class 1 was 191 (84.1%), obese class 2 was 98 (79%), and obese class 3 was 87 (81.3%), (chi2 (5) = 3.032, p = .695). When assessing need of mechanical ventilation, 159 (16.1%) of all patients needed ventilation. In each category: 3 (20%) underweight patients, 24 (13.7%) normal weight patients, 61 (18%) overweight patients, 33 (14.5%) obese class 1 patients, 22 (17.7%) obese class 2 patients, and 16 (15%) obese class 3 patients required ventilation (chi2 (5) = 2.613, p = .759). Analyzing days hospitalized, length of stay in each category was: underweight - 6 [5-12] days, normal weight - 7 [3-12] days, overweight - 6.5 [4-12] days, obese class 1 - 7 [4-12] days, obese class 2 - 7.5 [4-14] days, and obese class 3 - 7 [5-12] days (H (5) = 3.093, p =.686). CONCLUSION(S): In this cohort, BMI is not associated with higher mortality rates, longer hospitalization time, or need of mechanical ventilation among patients with COVID-19.

ABSTRACT

SESSION TITLE: Studies on COVID-19 Infections Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/18/2022 01:30 pm - 02:30 pm PURPOSE: Latent Epstein-Barr virus (EBV) and cytomegalovirus (CMV) are commonly reactivated in critically ill patients with severe infections. This study aimed to evaluate the proportion of reactivation of EBV and CMV and its impact on length of stay, need for ventilation, and Ichikado CT scores in patients with coronavirus disease 2019 (COVID-19). METHODS: A retrospective study was conducted comprising adult patients admitted to our hospital with COVID-19 infection from June 2021 to September 2021. Patients were divided into groups: virus-free, EBV-only, CMV-only, and EBV and CMV detected. Primary outcomes were length of stay, need for ventilation, and Ichikado CT score. Descriptive statistics, one-way ANOVA, Games-Howell, and Kruskal-Wallis tests were used. RESULTS: 189 patients were included with a median age of 51 years [41 – 66], 80 (42.3%) were female and 109 (57.7%) were male. CD4(+) counts were lower in all viral reactivation groups. EBV-only (157 cell/µl [93 – 279.2] ), CMV-only (82.5 cell/µl [65.5 – 323.7] ), both viruses (62.5 cell/µl [47.5 – 135.5]) and virus-free (221 cell/µl [117 – 318]), (H(3) = 12.029, p = < 0.01). A significant increase in the Ichikado CT score was seen in the viral reactivation groups. EBV 186.5 [43.6], CMV 177.5 [41.6], both-viruses group 204 [50.3] vs. virus-free 161 [45.8],( H(3) = 15.770, p = < 0.01). There was an increase in days of hospitalization when comparing the virus-free and the viral reactivation groups. EBV (9 days [5.5-15.5]), CMV (17 days [3-33]), both viruses (23 days [8-31]) vs. virus-free (5 days [3.5-9]), (H(3) = 15.487, p = < 0.01). Regarding the need for assisted ventilation, there was no difference between groups. 7 (9.1%) patients in the virus-free group, 29 (29.9%) patients in the EBV group, 2 (33.3%) patients in the CMV group, and 2 (22.2%) patients in the both-viruses group needed mechanical ventilation (X2 (3, N=189) = 11.699, p= 0.08). Additionally, a statistically significant decrease in albumin levels on admission was found in the EBV-only patients compared to the virus-free group, (3.4 g/dL [0.44] vs 3.75 g/dL [0.46], F(3,185) = 5.483, p = < 0.01). CONCLUSIONS: Viral reactivation is associated with lower CD4(+) count, an increase in length of stay, and higher Ichikado CT scores. CLINICAL IMPLICATIONS: EVB and CMV reactivation is associated with low CD4(+) counts and longer hospital stay.

ABSTRACT

SESSION TITLE: Biological Markers in Patients with COVID-19 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. 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-19 DISCLOSURES: No relevant relationships by David Akinwale No relevant relationships by Angelica Almaguer No relevant relationships by Sushen Bhalla No relevant relationships by Ailine Canete Cruz No relevant relationships by Ndiya Emeaba Speaker/Speaker's relationship with johnson and johnson Please note: approx year 2000 Added 03/31/2022 by Joseph Gathe, value=Honoraria clinical research relationship with gilead Please note: since 1990 Added 03/31/2022 by Joseph Gathe, value=Grant/Research clinical research relationship with ansun Please note: 2020 Added 03/31/2022 by Joseph Gathe, value=Grant/Research Support clinical research relationship with regeneron Please note: 2020 Added 03/31/2022 by Joseph Gathe, value=Grant/Research Support No relevant relationships by Jesus Salvador Gonzalez Lopez No relevant relationships by Najia Hussaini No relevant relationships by Claudia Ramirez No relevant relationships by Salim Surani No relevant relationships by Daryelle Varon No relevant relationships by Joseph Varon No relevant relationships by Mohamed Ziad

ABSTRACT

SESSION TITLE: Biological Markers in Patients with COVID-19 Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/18/2022 01:30 pm - 02:30 pm PURPOSE: Common markers of inflammation in COVID-19 include erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and ferritin. We aimed to find an association between creatine Phosphokinase (CPK) and other inflammatory markers and enzymes, and their effect on length of hospital stay, and the Ichikado CT scores. METHODS: Retrospective study of the data of 264 adult patients admitted to our hospital between June and September 2021, with COVID-19. Patients were divided into groups with CPK of greater or less than 200mg/dL. Each was assessed for its association with CRP, ESR, ferritin, and lactate dehydrogenase (LDH), length of hospital stay, and Ichikado CT score. Descriptive statistics, Mann Whitney-U were used to address statistical significance. RESULTS: 264 patients were included, median age was 51.95 years [41-63]. 143(53.2%) were male. The median highest CRP value in patients with CPK of <200 mg/dL was (55 mg/L [24-96.4] vs 97.4 mg/L [50.1-139]) in those with CPK of >200 mg/dL, (U=(131,118) =5097, z=-4.638, p<0.01). The median highest ESR with CPK of <200 mg/dL was (72 mm/hr [51.0-102.5] vs 89 mm/hr [60-109]) in those with CPK of >200 mg/dL, (U= (133,119) =6862.5, z=-1.820, p=0.069). The median highest ferritin value in those with CPK of <200 mg/dL was (388.5 ng/mL [187.1-804.4] vs 1046 ng/mL [462.1-1600]) in those with CPK of >200 mg/dL, (U=(132,118) =4156.5, z=6.3985, p<0.01). The median highest phosphate level in patients with CPK of <200 mg/dL was (3.6 mg/dL [3.3-4.2] vs 3.8 mg/dL [3.4-5.2]) in those with CPK of >200 mg/dL,(U=(133,119) =6487.5, z=-2.471, p=0.013). The median highest LDH level in patients with CPK of <200 mg/dL was (352 IU/L [271.5-459] vs 673.5 IU/L[411.7-980.2]) in those with CPK of >200 mg/dL, (U=(113,106) = 2201, z =-8.084, p<0.01). The median highest Ichikado CT score in patients with CPK of <200 mg/dL was (150[130-190] vs 190[140-222.5]) in those with CPK of >200 mg/dL,(U= (142,209) =5188, z=-4.482, p<0.01). The length of hospital stay in patients with CPK of<200 mg/dL was (5 days [3-8] vs 9 days [5-17]) in those with CPK of >200 mg/dL, (U=(144,120) = 5533, z =-5.049, p<0.01). CONCLUSIONS: CPK has a statistically significant association with CRP and ferritin levels but not ESR. Imaging disease severity at presentation (Ichikado CT score) was associated with higher CPK levels. CLINICAL IMPLICATIONS: CPK is another marker of disease severity in COVID-19.

ABSTRACT

SESSION TITLE: Biological Markers in Patients with COVID-19 Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/18/2022 01:30 pm - 02:30 pm PURPOSE: A significant reduction of CD4(+) cells and marked inflammatory activity in moderate and severe COVID-19 cases are seen, both associated with a poor prognosis. This study aimed to assess the association of low CD4(+) counts with inflammatory markers, length of stay, and ICKIKADO 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. CD4(+) count was obtained and patients were divided into two categories: less than 200 cells/μl and more than 200 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 scores, and correlation of CD4(+) count and inflammatory markers. Descriptive statistics, and Mann-Whitney-U methods were used. RESULTS: 264 patients were included, median age was 50 years [41-61]. 143(54.2%) were male. There was a statistically significant difference in LOS for patients with CD4(+) counts <200 cells/μl vs > 200 cells/μl CD4(+) (9 days [5-18]vs 6 days [4-9]), U=(111,107)=4330, z=-3.466, p <0.01). The Ichikado CT score was significantly different between groups (190[150-220]vs 160[128.7-192.5], U=(106,102)=3706.5, z=-3.923, p<0.01). IL-10 values and IL-6 values were higher in those patients with CD4(+) less than 200 cells/μl, as compared to higher CD4(+) counts. median IL-10 was (25.2 pg/ml [17-72.45 ] vs 15.7 pg/ml [9.4-26.8 ], U=(109,100)=3463, z=-4.550, p<0.01), and median IL-6 was (23 pg/ml [10.5-99] vs 12 pg/ml [3.77-39], U=(104, 96)=3444.5, z=-3.785, p<0.01). Ferritin was increased in patients with CD4(+) counts lower than 200 cells/μl when compared to counts more than 200 cells/μl (850.2 ng/mL [373.3-1600] vs 541.5 ng/mL [245.1-1034.6], U=(110,106) =4543.5, z=-2.813, p=<0.01). CRP had a similar pattern (82 mg/L[49.5-138.2] vs 60.8 mg/L[30-114.2]), U=(111,105)=4478, z=-2.940, p=<0.01), d-Dimer (2.2 mg/L[0.55-7.14] vs 0.7mg/L[0.37-1.75], U=(111,107)=3992.5, z=-4.180, p<0.01), LDH (630 IU/L[371-888] vs 381 IU/L[276-520.2], U=(102,92)=2631.5,z=-5.227, p<0.01) and troponin (0.024 ng/mL[0.012-0.048] vs 0.012 ng/mL[0.007-0.027], U=(91,90)=2925, z=-3.321,P<0.01). The only inflammatory marker that was not statistically significant different was ESR (86 mm/hr[60-110] vs 72 mm/hr[50-100], U(111-107)=5113, z=-1.773,P=0.076). CONCLUSIONS: CD4(+) counts below 200 cells/μl are associated with increased inflammatory markers, a longer hospital stay, and higher Ichikado CT scores. CLINICAL IMPLICATIONS: CD4(+) count below 200 cells/μl is other indicator of disease severity in COVID-19 DISCLOSURES: No relevant relationships by David Akinwale No relevant relationships by Angelica Almaguer No relevant relationships by Sushen Bhalla No relevant relationships by Ailine Canete Cruz No relevant relationships by Ndiya Emeaba Speaker/Speaker's relationship with johnson and johnson Please note: approx year 2000 Added 03/31/2022 by Joseph Gathe, value=Honoraria clinical research relationship with gilead Please note: since 1990 Added 03/31/2022 by Joseph Gathe, value=Grant/Research clinical research relationship with ansun Please note: 2020 Added 03/31/2022 by Joseph Gathe, value=Grant/Research Support clinical research relationship with regeneron Please note: 2020 Added 03/31/2022 by Joseph Gathe, value=Grant/Research Support No relevant relationships by Jesus Salvador Gonzalez Lopez No relevant relationships by Najia Hussaini No relevant relationships by Claudia Ramirez No relevant relationships by Salim Surani No relevant relationships by Daryelle Varon No relevant relationships by Joseph Varon No relevant relationships by Mohamed Ziad
