Assessment of liver function in COVID-19

Introduction: COVID-19 is an infectious disease caused by the SARS-CoV-2 virus that commonly involved the respiratory system. However, the virus can affect any organ in the body including the liver. Hepatic involvement in COVID-19 could be related to the direct cytopathic effect of the virus, an uncontrolled immune reaction, sepsis, or drug-induced liver injury. Background: The current study aims to evaluate the relevance of liver enzyme derangement in COVID-19. Methods: The sample size of 165 patients, tested positive for covid 19 and underwent liver enzyme testing. These patients were categorized into mild, severe, and critical diseases based on clinical evaluation, radiological findings, and biochemical parameters. Results: Of 165 patients selected 103 (62.4%) have mild disease, 40(24.2%) have severe and 12(7.2%) suffered from the critical disease. 48(29.1%) patients show deranged liver function. 83.3% of critical patients and 45% of severe patients show deranged liver function.9.09%of patients died due to severe COVID-19 infections showing moderately to severe liver function derangement. Conclusions: This study concludes that the severity of COVID-19 disease may increase due to chronic liver disease, particularly fatty liver. Atypical ALT and AST levels during hospitalization were indicative of liver injury and correlated with the severity of patients.

Clinical outcome in patients with COVID-19 and comparison to serum LDH and D-dimer levels

Background: D-dimer and LDH are crucial biomarkers, particularly in view of the fact that they have been strongly linked to COVID-19 infection and have been linked to worse consequences in people who have severe viral infections. Objectives: To determine how D-dimer and LDH correlated with clinical effects in COVID-19 patients who were hospitalised and how they forecasted the severity of COVID-19 patients. Material and Methods: This was cross-sectional research conducted relatively early in the second wave of the pandemic. A total of 110 patients diagnosed with COVID-19 and admitted to the ICU from January 2021 to June 2021, were included in the study. The clinical outcome was evaluated in terms of discharge and death among patients requiring various forms of assisted ventilation. Results: The average age of patients was 53.16 years (+or- 18.47 years). 35.5% of the patients were with comorbidities of which diabetes, hypertension, and COPD were around 80%. D-dimer was deranged in 2.7% of the subjects and LDH was deranged in 60% of the study subjects at the time of admission. Coming on to the outcome, all patients were put on assisted ventilation with 71.8% on NIV, 20% on HFNO, 1% on CPAP, and 7.2% on MV. During their hospital stays, 6 (5.45%) patients died and the remaining patients were discharged. A higher D-dimer value (> 1.5 g/ml) during the hospital stay was found to be statistically significant with assisted ventilation and deaths of the admitted study subjects. Conclusion: In our investigation, the biomarker D-dimer value was more associated than LDH with mortality in patients with COVID-19 infection.

Factors affecting admission to intensive care unit of COVID-19 patients in the Kingdom of Bahrain

Objective: Coronavirus disease-2019 (COVID-19) is a newly emerging infectious disease that has become a global pandemic. This study aimed to identify the risk factors at presentation to predict intensive care unit (ICU) admissions. Materials & Methods: This retrospective observational study recruited 188 confirmed laboratory COVID-19 patients who were hospitalized in Jidhafs Maternity Hospital (JMH) from 1st June to 5th July 2020. Univariate and multivariate analyses were used to Explore risk factors associated with the increased risk of ICU admission. Results: The study revealed that older age (>60 years old) (16[38.1%], P=0.044), male gender (30 [40.0%], P=0.000) were significantly associated with the increased risk of ICU admissions. The most prevalent symptoms in admission were myalgia (13[40.6%], P=0.035), fever (39[34.2%], P=0.002) and cough (37[31.4%], P=0.032). In addition, raised serum level of alanine amino-transferase (ALAT) (34.7% vs. 20.7%, P=0.033), D-dimers (30.7% vs 12.2%, P=0.012), lactate dehydrogenase (LDH) (31.6% vs 0.0%, P=0.025) and ferritin (37.7% vs 16.7%, P=0.011) found to be important predictor of ICU admission. Conclusion: The finding indicates that older age, male gender, with increased alanine transferase (ALT), increased lactate dehydrogenase (LDH), high D-dimer and high ferritin was associated with an increased risk of ICU admissions. Identification of such factors will help to detect people who are more likely to develop severe COVID-19 disease and will help physicians to determine if patients need regular health care or ICU admission.

Effectiveness of atorvastatin in reducing inflammatory markers and hospitalization period in adults with COVID-19: a randomized clinical trial

Background and Objectives: Statins, which are primarily used for controlling blood cholesterol levels, have a well-known role in inhibiting the inflammatory process and reducing mortality rate of infectious diseases. This study aims to evaluate the effect of atorvastatin along with standard treatment protocol in hospitalized adults with COVID-19. Methods: This randomized controlled clinical trial was conducted on adults hospitalized due to COVID-19 infection at Shahid Beheshti Hospital in Qom, Iran from April to September 2020. They were randomly divided into groups of treatment (n=37, receiving atorvastatin 40 mg daily for 30 days plus standard treatment protocol) and control (n=37, receiving standard treatment protocol alone). The data were analyzed in SPSS v.22 software using chi-square, paired t-test, and ANOVA. P < 0.05 was statistically significant. Results: The CRP level in the atorvastatin-treated group decreased significantly such that there was a significant difference between the two groups after 30 days (P=0.01). There was no significant difference in Spo2 level on the discharge day. The length of hospitalization in the atorvastatin-treated group was significantly reduced compared to the control group (P < 0.05). Conclusion: The use of atorvastatin as an adjunctive treatment method, can significantly reduce the length of hospitalization and CRP level after 30 days in hospitalized patients.

Elevated platelet large cell-ratio levels as a demonstrative biomarker associated with severe COVID-19

Objective: To represent the effects of the severity of COVID-19 infection on platelet large cell ratio (PLC-R). Materials and Methods: A hundred eleven patients diagnosed with COVID-19 were included in this study. Positive results for SARS-CoV-2 based on a typical RT-PCR test performed on nasopharyngeal swabs were included in the study Groups. Patients with COVID-19 were divided into three Groups according to their chest CT features. Group 1 (45 patients) was defined as mild, Group 2 (34 patients) as moderate and Group 3 (32 patients) as severe. Complete blood count parameters including platelet volume indices (PVI) values, CRP, D-dimer and lipid profiles were analyzed in all study participants. The correlation between COVID-19 patient Groups and PLC-R values were demonstrated using SPSS and ANFC methods. Results: The significant impact of our study is that PLC-R was significantly higher in the severe COVID-19 patients than the moderate and mild patients. Spearman's rho correlation analysis showed that PLC-R and WBC levels increased, and Htc and Hb levels decreased with the severity of the disease. ROC analysis showed that PLC-R > 38.3% had 59.4% sensitivity and 68.4% specificity in predicting severe COVID-19 disease (AUC 0.672, %95 CI 0.560, 0.784;p=0.005, cut off=38.3). CRP, ferritin and D-dimer values of the patients in Group 3 were significantly higher than the patients in Group 1, and the iron values of the patients in Group 3 were significantly lower than the patients in Group 1. Conclusion: PLC-R values are useful for anticipating acute thrombotic events. Based on the results of our study, PLC-R values can be used as appropriate biomarkers to describe the severity of COVID-19 infection.

C-reactive protein lymphocyte index in COVID-19: a little-explored tool

Background: COVID-19 develops severe inflammatory responses that can lead to death. It is essential in a pandemic to have accessible instruments to estimate the prognosis of the disease. The lymphocyte-to-C-reactive protein ratio (LCR) is a predictive biomarker studied in oncology, which could have some advantages in COVID-19 patients in the early stages of the disease. Our objective was to estimate the risk of LCR < 100 and mortality in hospitalized patients with COVID-19. Methods: hospitalized patients with COVID-19 seen between March to October 2020 were included. The patients were grouped according to LCR < 100 and LCR > 100. A Cox regression model was performed to estimate the association between LCR < 100 and mortality. Results: we included 730 patients with COVID-19. The mean age at diagnosis was 49.9 years (SD 16.8) and 401 (55%) were men. Cox regression model showed an association between LCR < 100 and mortality (HR 6.2;95% CI 1.6 to 23.5;p 0.008), adjusting by age. severe pneumonia, intensive care requirements, and comorbidities. Conclusion: LPCR < 100 in the initial assessment of hospitalized patients with COVID-19 suggests a higher risk of mortality.

Exploring Potential Biomarkers and Molecular Mechanisms of Ischemic Cardiomyopathy and COVID-19 Comorbidity Based on Bioinformatics and Systems Biology.

Cardiovascular complications combined with COVID-19 (SARS-CoV-2) lead to a poor prognosis in patients. The common pathogenesis of ischemic cardiomyopathy (ICM) and COVID-19 is still unclear. Here, we explored potential molecular mechanisms and biomarkers for ICM and COVID-19. Common differentially expressed genes (DEGs) of ICM (GSE5406) and COVID-19 (GSE164805) were identified using GEO2R. We performed enrichment and protein-protein interaction analyses and screened key genes. To confirm the diagnostic performance for these hub genes, we used external datasets (GSE116250 and GSE211979) and plotted ROC curves. Transcription factor and microRNA regulatory networks were constructed for the validated hub genes. Finally, drug prediction and molecular docking validation were performed using cMAP. We identified 81 common DEGs, many of which were enriched in terms of their relation to angiogenesis. Three DEGs were identified as key hub genes (HSP90AA1, HSPA9, and SRSF1) in the protein-protein interaction analysis. These hub genes had high diagnostic performance in the four datasets (AUC > 0.7). Mir-16-5p and KLF9 transcription factor co-regulated these hub genes. The drugs vindesine and ON-01910 showed good binding performance to the hub genes. We identified HSP90AA1, HSPA9, and SRSF1 as markers for the co-pathogenesis of ICM and COVID-19, and showed that co-pathogenesis of ICM and COVID-19 may be related to angiogenesis. Vindesine and ON-01910 were predicted as potential therapeutic agents. Our findings will contribute to a deeper understanding of the comorbidity of ICM with COVID-19.

Cluster analysis of biochemical markers as predictor of COVID-19 severity

Numerous blood biomarkers are altered in COVID-19 patients;however, no early biochemical markers are currently being used in clinical practice to predict COVID-19 severity. COVID-19, the most recent pandemic, is caused by the SRS-CoV-2 coronavirus. The study was aimed to identify patient groups with a high and low risk of developing COVID-19 using a cluster analysis of several biomarkers. 137 women with confirmed SARS CoV-2 RNA testing were collected and analyzed for biochemical profiles. Two-dimensional automated hierarchy clustering of all biomarkers was applied, and patients were sorted into classes. Biochemistry marker variations (Ferritin, lactate dehydrogenase LDH, D-dimer, and C- reactive protein CRP) have split COVID-19 patients into two groups(severe cases and non-severe cases groups). Ferritin, lactate dehydrogenase LDH, D-dimer and CRP were markedly increased in COVID-19 patients in the first group (severe cases). Our findings imply that early measured levels of (Ferritin, lactate dehydrogenase LDH, D-dimer, and C- reactive protein CRP) are linked to a decreased probability of COVID-19 severity. Elevated levels of this biomarker may predict COVID severity development.

Newly diagnosed diabetes in patients with COVID-19: in a tertiary care center in central India

Background: Diabetes mellitus (DM) is associated with adverse clinical outcomes and high mortality in patients with corona virus disease 2019 (COVID-19). The relationship between diabetes and COVID-19 is known to be bidirectional. Aim: To analyze the rate of new-onset diabetes in COVID-19 patients and asses the clinical outcomes of new-onset diabetes and hyperglycemia among COVID-19 patients Methods: This cross sectional study was enrolled individuals admitted with COVID-19 and newly diagnosed diabetes mellitus. (DM);based on laboratory diagnoses. Results: Analysis showed that 13.7% (84/610) of COVID-19 patients had newly diagnosed DM. Majority of the newly diagnosed diabetic patient was male (58.3%), most of them (33.3%) were 51-60 year age group. Higher incidence of DM was reported in urban population (54.8%). The significant risk factors of diabetes were found family history of diabetes, (53.6%) and obesity (72.6%). Hypertension was the most common (61.7%) comorbidity associated with the DM. Conclusions: Diabetes diagnosed at COVID-19 presentation is associated with lower glucose but higher inflammatory markers and ICU admission, suggesting stress hyperglycemia as a major physiologic mechanism.

Serum total bilirubin and aminotransferases in patients with COVID-19 in Nellore district of South Andhra Pradesh

BACKGROUND: Corona virus disease-19 (COVID -19) infection is an acute infectious disease caused by a newly discovered beta corona virus, severe acute respiratory syndrome corona virus 2 (SARS-CoV-2). While the primary target organ is the lungs, involvement of many other organs is often evident in patients with COVID-19. There is emerging evidence to suggest association of SARS-CoV-2 infection with development of many liver abnormalities. The purpose of this study was to evaluate the prevalence of abnormal liver parameters in COVID-19 patients and their variation in moderate and severe cases. METHODS: This is a retrospective study. All patients with COVID -19, between the ages 20-75 years, encountered between April and May 2021, were included for the study and compared with age-matched controls. Severity of infection was defined based on the presence of symptoms, oxygen saturation, need for respiratory and intensive care support. Liver parameters such as serum total bilirubin (TBIL), serum aminotransferases, alanine aminotransaminase (ALT) and aspartate aminotransaminase (AST) were analysed. Inflammatory markers such as C-reactive protein (CRP) and D-dimer were also included for assay. RESULTS: A total of 52 patients were encountered during the study period. Of these, 29% (15/52) required intensive care. Abnormal liver parameters were observed in 14 (27%) patients, and were significantly elevated compared to healthy controls. Liver dysfunction was markedly profound in severe infection than those with moderate disease. Higher levels of CRP and D-dimer were noted in severe patients of COVID-19. CONCLUSIONS: Mild liver abnormalities in the form of elevated ALT and AST are seen in COVID-19 patients suggesting mild or no liver injury. These abnormal parameters do not generally lead to significant liver function impairment/failure and no specific treatment is required.

Investigation of the relationship between C-reactive protein and lymphocyte counts in mortality and prognosis of patients with COVID 19

Introduction: Testing C-reactive protein with a decrease in blood lymphocytes can help in the rapid diagnosis of Covid-19 disease. Therefore, this study was performed to investigate the relationship between C-reactive protein levels and lymphopenia on mortality from Covid 19 disease. Methods: The present study is a cross-sectional analytical study that was performed on 179 patients with Covid-19 referred to Imam Hossein Hospital in Shahroud. Subjects with positive PCR test, presence of C-reactive protein and lymphocytes in the experiments, outpatient referral or hospitalization in normal wards, ICU, and CCU of the hospital were included in the study. Chi-square and independent t-tests were used for statistical analysis using SPSS software version 23. The significance level was considered 0.05. Results: 179 patients were included in the study, 51.4% of whom were male. The mortality rate in the lymphopenia group was 15.9%, which was higher than the group with normal lymphocytes, and the mean age of those who died of the disease was significantly higher than those who improved (P=0.01). The results also showed that the mean age in people with high CRP is higher (P=0.01). Conclusion: According to the present study and the higher mortality rate in patients with lymphopenia, lymphopenia can be suggested as an indicator of the prognosis of patients, and also CRP can be considered a factor for the risk of mortality in patients.

Background: The severe acute respiratory syndrome coronavirus called the novel coronavirus caused the pandemic coronavirus disease 19 (COVID-19). All over the world, SARS-CoV-2 pneumonia is causing significant short-term morbidity and mortality, but the medium-term impact on lung function and quality of life of affected patients is still unknown. Aims: To assess clinical, laboratory, and radiological parameters of COVID-19 Patients and to correlate radiological findings and disease severity among patients. Methodology: In this retrospective observational study a total of 630 patients with radiologically confirmed pneumonia and COVID-19 RT PCR positive were included from a tertiary care centre in Pune, Maharashtra, following their voluntary informed consent. Patients underwent clinical, laboratory, and radiological investigations. Results: It was observed that the majority 174 (27.6%) were in the age group of 31 to 40 years and male predominance was observed compared to female. The majority of the patients 314 (49.8%) had mild, 232 (36.8%) were moderate and 84 (13.3%) had severe illness as per CT scores (HRCT Chest score). Mean BSL levels were 181 +or- 81.44, mean pulse rate was 94.03 +or- 14.93 bpm, mean respiratory rate was 22.84 +or- 3.71cpm, systolic blood pressure was 129.09 +or- 13.18 mmHg, diastolic blood pressure was 82.80 +or- 9.67 mmHg and mean temperature was 98.56 +or- 1.67 degrees F. The mean ferritin levels were 181 +or- 81.44, the mean LDH level was 94.03 +or- 14.93, mean HbA1C was 7.45 +or- 1.68. The mean NLR was 5.51 +or- 2.41, the mean WBC count was 7238.38 +or- 4942.23 and the mean hematocrit was 39.69 +or- 4.80. The mean D dimer level was 402.29 +or- 424.70, median levels were 260 (170-450). 503 (79.8%) had CRP levels more than 5 and 127 (20.2%) had levels less than 5. The mean duration of hospital stay was 9.18 days +or- 4.34 days. Majority 570 (90.5%) had fever, 493 (78.3%) had cough, 286 (45.4%) had breathlessness, 66 (10.5%) had sore throat. Other symptoms include vomiting, and loose motion in 17 (2.7%). Among 630 subjects included in the present study, the majority 584 (92.7%) have recovered/were discharged from the hospital and 46 (7.3%) succumbed to the illness. The mean SGOT and SGPT levels were 44.86+or- 31.29 and 43.60 +or- 31.25 respectively. Mean serum creatinine and BUN levels were 0.87+or- 0.80 and 13.96 +or- 9.46 respectively. The mean values of pulse rate, systolic blood pressure, diastolic blood pressure, respiratory rate and temperature showed an increasing trend across the grades of severity. Conclusion: We concluded that age, gender, blood sugar level, blood pressure, clinical symptoms, comorbidities, inflammatory biomarkers and CT severity score were independently associated with the severity and mortality based on our findings.

Can 4C score predict mortality due to COVID-19 pneumonia in Syria? An observational study

INTRODUCTION: The aim of this study was to investigate the patients treated for COVID -19 in pandemic hospitals in northwestern Syria. METHODS: The study evaluated all patients hospitalized for COVID -19 by the pandemic emergency departments of hospitals in northwestern Syria between July 1, 2020 and December 01, 2020. Demographic, clinical, laboratory, and imaging characteristics, 4C mortality index scores treatments, and progressions of all patients hospitalized for COVID -19 were retrospectively reviewed. RESULTS: A total of 991 patients admitted to hospitals in northwestern Syria by pandemic emergency services for treatment and follow-up were included. 114 patients from Afrin Hospital, 251 from Al-Bab Hospital, 527 from Azez Vatan Hospital, and 99 from Jarablus Hospital were included in the study. When comparing the mortality and hospitalization rates of the patients according to the 4C Mortality Score, it was found that the patients with high-risk score in Azez and Jarabulus hospitals and those with very high-risk score in El Bab hospital had significantly higher mortality and hospitalization rates in the ICU (p<0.05). DISCUSSION AND CONCLUSION: The data that can be obtained from studies evaluating the approach to the COVID -19 epidemic in this and similar regions are important for the development of health services in disadvantaged regions. We believe that our study will make an important contribution to the literature, as it is the first and only data reflecting hospitalized patients with COVID -19 in this region.

Monocyte distribution width - new sepsis biomarker

Sepsis is a global health problem, annually over 45 million patients are diagnosed and over 11 million deaths are recorded. Activation of monocytes in sepsis by the pathogen agent or hypoxia brings about functional, morphological and phenotypic changes in these cells. Monocyte Distribution Width (MDW) is a new biomarker, defined as a measure of monocyte size heterogeneity and has been approved by the Food and Drug Administration for the early diagnosis of sepsis in the adult patient in the emergency department. In intensive care services, this biomarker can be used as a prognostic index in the follow-up of patients with sepsis. The indicator is a measure of the increased morphological variability of monocytes in response to infections, regardless of bacterial, viral or fungal etiology. This new marker also has increased values in the infection with COVID-19 and correlates positively with the severity of the disease.

A study of association of eosinophil count with severity and outcome in corona virus disease (COVID-19) in paediatric cases

Recently, COVID-19 has been investigated for questions pertaining to eosinophils. Eosinopenia, often known as a decrease in eosinophil levels, was identified as a characteristic feature associated with SARSCoV- 2 infection. However, in the past researchers have found conflicting evidence on the connection between eosinopenia and the severity of the disease. It is not quite obvious if these changes occurred as a consequence of the immunomodulation that the medication provided or of the disease process itself. In addition, additional study is required to shed light on the possible connection that exists between the eosinophil count and the development and severity of COVID-19. The current analysis was to report changes in the eosinophil count in symptomatic COVID- 19 patients and to link such changes with severity and prognosis. The purpose of the investigation was also to record variations in the eosinophil count.

Laboratory and clinical findings in hospitalized pregnant women with COVID-19 based on disease outcome during the outbreak of Delta variant in Ardabil (summer and autumn 2021)

Introduction: Due to the high risk of Covid-19 disease, especially delta variant in pregnant women, as well as the novelty of this epidemic in the world and the lack of similar studies in Iran and the region, it seems necessary to perform a study on mortality rate and laboratory and clinical findings of the disease in pregnant women. Therefore, this study was performed aimed to determine the laboratory and clinical findings in hospitalized pregnant women with Covid -19 based on disease outcome during the outbreak of Delta variant (summer and autumn 2021) in Ardabil province. Methods: In this cross-sectional and descriptive study, all pregnant women with Covid-19 admitted to the hospitals of Ardabil province in summer and autumn 2021 at the time of delta outbreak were included. Finally, 187 infected pregnant mothers were studied. Demographic information, clinical signs and laboratory findings were studied in all mothers. Data were analyzed by SPSS (version 24) and Fisher Exact test and Pearson Correlation. P<0.05 was considered statistically significant. Results: Of the 187 infected pregnant women, 8 mothers died. Comorbidity was observed in 41 pregnant women. The most common clinical finding was shortness of breath (Dyspnea) and cough, and the most common laboratory finding was lymphopenia. Comparing the cured and dead mothers according to laboratory findings using Fisher's exact test showed that the difference between ALT (p <0.05), lactate dehydrogenase (p <0.001), AST (p <0.001), BS (P <0.05), creatinine (p <0.05) and total bilirubin (p <0.05) were statistically significant between the two groups. Conclusion: Infection to delta variant of Covid-19 disease resulted in 187 hospitalizations and 8 deaths of pregnant mothers in Ardabil province. Shortness of breath (Dyspnea) and cough were the most common clinical findings and lymphopenia was the most common laboratory finding.

C-reactive protein (CRP) medium and severe symptoms levels of COVID-19

Coronavirus Disease 2019 (COVID-19) is a disease caused by SARS-CoV-2 and has caused a global pandemic. Patients with COVID-19 can experience symptoms such as fever, dry cough, headache, and shortness of breath which can lead to pneumonia. Excessive inflammation is considered a leading cause of critical illness and death in COVID-19 patients. C-Reactive Protein is a sensitive indicator as an early marker of infection and inflammation. This study presents an overview of the difference in the average CRP levels between patients with moderate and severe confirmed COVID-19 symptoms at UKI Hospital for June-September 2021. The study design was cross-sectional with descriptive and analytical data presentation obtained from medical record documents at UKI Hospital. The average CRP level of COVID-19 patients with moderate symptoms is 63,705 mg/L, totaling 139 patients. The average CRP level of COVID-19 patients with severe symptoms is 132,050 mg/L, totaling 57 patients. The results obtained from the Mann-Whitney test between groups of patients with moderate and severe COVID-19 showed a significant difference between CRP levels with moderate and severe symptoms with p <0.05.

Study of liver function test in COVID-19 patients and its correlation with inflammatory markers from Hubballi, Karnataka

BACKGROUND: Since its reporting in December 2019, SARC-COV-2 (COVID -19) has infected more than 230 million people over the world by colonising the respiratory tract, however very little is known about its effect on liver and how the liver injury affects disease prognosis. This study was done to assess the hepatic profile in SARC-COV-2 infection along with inflammatory markers. METHODS: This is a single centred prospective observational study. 400 patients with real time polymerase chain reaction (PCR) confirmed COVID 19 infection admitted in KIMS, Hubballi were taken for study. Patients with decompensated liver disease were excluded from the study. Clinical examination and laboratory investigations including liver function test (LFT), renal function test (RFT), complete blood count (CBC), chest X-ray, D-dimer, ferritin, lactate dehydrogenase (LDH), C reactive protein (CRP) was done for all the patients. RESULTS: Out of the 400 covid-19 positive patients admitted, 286 (71.5%) had abnormal liver enzymes. Significantly raised liver enzymes were seen in males. Raised liver enzymes and inflammatory markers were associated with poor outcome of the disease. Significant reduced albumin was associated with poor outcome of the disease. Significantly raised aspartate transaminase (AST), alanine transaminase (ALT) levels were associated with increased severity of the disease. (P = 0.009 and 0.029 respectively). Significant positive relation was found between liver profile and inflammatory markers. CONCLUSIONS: Majority of patients admitted with SARS-CoV-2 had deranged liver profile. Higher proportion of abnormal liver enzymes were seen in males. Degree of liver injury increases with increasing severity of the disease. Even though abnormal liver enzymes were positively associated with elevated inflammatory markers and severity of the disease, more studies are needed to study implications of liver injury in prognosis of SARS-CoV-2 infection.

Clinical significance of serum interleukin 6 in elderly patients infected with severe acute respiratory syndrome Coronavirus 2 Omicron variant and its correlation with underlying diseases

Objective: To investigate the clinical significance of serum interleukin 6 (IL-6) in elderly patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) omicron variant and its correlation with underlying diseases. Methods: A total of 22 elderly patients (> 80 years old) infected with omicron variant, who were admitted to Department of Infectious Diseases, The First Affiliated Hospital of Naval Medical University (Second Military Medical University) from Apr. to Jun. 2022 and tested positive for SARS-CoV-2 RNA, were included. The level of serum IL-6 was measured by flow cytometry, and the level of serum C reactive protein (CRP) was measured by immunonephelometry. Patients were divided into pneumonia group (16 cases) and non-pneumonia group (6 cases) according to the imaging examination results, and were divided into severe group (severe and critical type, 5 cases) and non-severe group (mild and normal type, 17 cases) according to the condition. Binary logistic regression model and receiver operating characteristic (ROC) curve were used to analyze the correlation between serum IL-6 and CRP levels and the severity of the disease and whether it would progress to pneumonia. Meanwhile, the relationships between underlying diseases and serum IL-6 level were explored. Results: Among the 22 patients, 6 were mild, 11 were normal, 3 were severe, and 2 were critical. The baseline serum IL-6 level in the pneumonia group was significantly higher than that in the non-pneumonia group ([20.16+or-12.36] pg/mL vs [5.42+or-1.57] pg/mL, P=0.009), and there was no significant difference in baseline serum CRP level between the 2 groups (P > 0.05). There were no significant differences in baseline serum IL-6 or CRP levels between the severe group and the non-severe group (both P > 0.05). Logistic regression analysis showed that the baseline serum IL-6 and CRP might be related to pneumonia after infection with omicron variant (odds ratio [OR]=2.407, 95% confidence interval [CI] 0.915-6.328;OR=1.030, 95% CI 0.952-1.114). ROC curve analysis showed that the area under curve values of serum IL-6 and CRP in predicting the progression to pneumonia were 0.969 (95% CI 0.900-1.000) and 0.656 (95% CI 0.380-0.932), respectively, with statistical significance (Z=2.154, P=0.030). There were no significant differences in the baseline serum IL-6 level or proportions of severe patients or pneumonia patients among patients with or without hypertension, diabetes mellitus, coronary heart disease, chronic kidney disease or chronic obstructive pulmonary disease (all P > 0.05). The baseline serum IL-6 levels of the omicron variant infected elderly patients with 1, 2, and 3 or more underlying diseases were 12.50 (9.15, 21.75), 23.55 (9.63, 50.10), and 10.90 (5.20, 18.88) pg/mL, respectively, with no statistical significance (P > 0.05). Conclusion: For omicron variant infected patients, serum IL-6 level is significantly increased in patients with pneumonia manifestations and is correlated with disease progression. Serum IL-6 level is of great guiding significance to judge disease progression and evaluate efficacy and prognosis of elderly coronavirus disease 2019 patients.

Carcinoembryonic antigen (CEA) and other surrogate inflammatory biomarkers in COVID-19

It has been two years since the global outbreak of the highly contagious and deadly corona virus disease (COVID-19) caused by SARS-CoV-2 first emerged in China. Since then, various diagnostic, prognostic and treatment strategies undertaken to address the pandemic have been dynamically evolving. Predictive and prognostic role of various biomarkers in COVID-19 has been a subject of intense exploration. We aimed to determine the association of Carcinoembryonic antigen (CEA) and various surrogate inflammatory biomarkers with the severity of COVID-19 disease. This retrospective cohort study was carried out on 98 patients admitted in Jaypee Hospital, Noida with COVID-19 disease. Information regarding demographics, laboratory parameters and clinical history was collected from Hospital Information System. Serum levels of CEA and other biomarkers such as Neutrophil-lymphocyte ratio (NLR), C-reactive protein (CRP), Interleukin-6 (IL-6), Ferritin, and Procalcitonin (PCT) were assessed. Correlation analyses were performed between the parameters and acute respiratory distress syndrome (ARDS) stages. Logistic regression and ROC curve analysis were performed to assess the various parameters for distinguishing COVID-19 patients requiring ICU admission. Mean hospital stay, NLR, CEA, IL-6, CRP, Ferritin (P < 0.0001) and PCT (P = 0.01) were significantly higher in ICU patients when compared to general ward patients. NLR, median serum CEA, IL-6, and CRP levels were significantly higher in non-survivor compared to the survivors (P < 0.0001, 0.0341 and 0.0092). CEA correlated well with disease severity based upon ARDS classification and was a better marker to differentiate patient according to ARDS stages (ARDS 0 vs 2 P = 0.0006;0 vs 3 P < 0.0001;ARDS 1 vs 2 P = 0.0183;1 vs 3 P = 0.0006). The area under the Receiver operating characteristic (ROC) curve for CEA was 0.7467 (95% CI- 0.64885- 0.84459) which revealed the potential of CEA as a biomarker to distinguish COVID-19 patients requiring ICU admission. CEA can be used to predict the severity of COVID-19 associated ARDS as well as patients requiring ICU admission. Along with routine inflammatory biomarkers (NLR, CRP, IL-6, PCT, and ferritin), CEA should be used for early identification of critical COVID-19 positive patients and for assessing prognosis.
