Are neutrophil-to-lymphocyte ratios and large unstained cells different in hospitalized COVID-19 PCR-positive patients with and without diabetes mellitus?

OBJECTIVE: SARS-CoV-2 might present with multisystem involvement due to its entry into many cells with ACE2 receptors on their surfaces, such as heart, endothelial, and lung alveoli cells. Studies have indicated that COVID-19 infection causes a severe clinical presentation in diabetic patients due to dysregulation of the metabolic and immune systems. The hematological effects of COVID-19 and the relationship of lymphopenia with the severity of the disease have been reported previously. The parameter of percentage of large unstained cells (LUCs) reflects active lymphocytes and peroxidase-negative cells. The neutrophil-to-lymphocyte ratio (NLR) is another reliable marker of inflammation in cases of cardiac diseases, solid tumors, and sepsis. The present study aimed to evaluate whether the parameters of LUCs and NLR differed between diabetic and nondiabetic individuals with COVID-19. Associations with disease severity were also sought. MATERIALS AND METHODS: In our retrospective study, the data of 1,053 patients [230 diabetic patients (21.83%) and 823 nondiabetic patients (78.15%)] were reviewed. The white blood cell (WBC) count, neutrophil count, neutrophil%, lymphocyte count, lymphocyte%, LUC count, %LUCs, NLR, platelet count, hemoglobin level, HbA1c, history of diabetes, surveillance during hospitalization, and pulmonary infiltration status within the first 24 hours after admission to the hospital were analyzed from the records. RESULTS: When diabetic patients were compared with nondiabetics, the age [65 (20-90) vs. 42 (18-94) years], WBC count [6.72 (2.6-24.04) vs.  5.91 (1.35-52.68)], neutrophil count [4.29 (1.28-65) vs. 3.68 (0.02-50.47)], neutrophil% [67.53±12.3 vs.  64.08±13.28], NLR [3.35 (0.83-38.11) vs. 2.48 (0.01-68.58)], and LUC count [0.11 (0.03-0.98) vs. 0.1 (0.02-3.06)] of the diabetic group were found to be higher and these differences were statistically significant (p<0.001, p<0.001, p<0.001, p<0.001, p<0.001, and p=0.015, respectively). CONCLUSIONS: We determined that LUC counts and NLR values in COVID-19-positive patients with diabetes were statistically significantly higher compared to nondiabetic patients.

Coronavirus Disease-Induced Acute Myocarditis: Two Clinical Presentations with Different Electrocardiographic Findings

Background: In this report, we present two cases of coronavirus disease (COVID-19)-related acute myocarditis (AM) with different clinical presentations and electrocardiographic (ECG) findings. Case Report: The first case was a 33-year-old male patient who presented with chest pain to the emergency department (ED). The ECG result suggested an acute coronary syndrome (ACS). However, coronary angiography (CAG) results showed normal coronary arteries, and the cardiac magnetic resonance imaging findings were compatible with COVID-19-induced AM. The ECG revealed a normalization of the T-wave negativity in the anterolateral precordial leads. The second case was a 41-year-old female patient who presented with ST-elevation myocardial infarction (STEMI) to the ED. CAG revealed normal coronary arteries, and the reverse-transcription polymerase chain reaction test result for COVID-19 was positive. The patient was diagnosed as having COVID-19-induced AM. Conclusion: Our cases demonstrate that clinicians should be aware that some patients with COVID-19-induced AM can present with ECG findings mimicking ACS, including STEMI.

Prognostic significance of N-Terminal Pro-BNP in patients with COVID-19 pneumonia without previous history of heart failure

Introduction: The objective of the present research was to evaluate the possible association between the N-terminal pro-brain type natriuretic peptide (NT-proBNP) levels and in-hospital mortality in coronavirus disease 2019 (COVID-19) pneumonia patients who did not have pre-existing heart failure (HF). Methods: A total of 137 consecutive patients without pre-existing HF and hospitalized due to COVID-19 pneumonia were enrolled into the current research. The main outcome of the research was the in-hospital death. The independent parameters linked with the in-hospital death were determined by multivariable analysis. Results: A total of 26 deaths with an in-hospital mortality rate of 18.9% was noted. Those who died were older with an increased frequency of comorbidities such as hypertension, chronic kidney disease, coronary artery disease, stroke and dementia. They had also increased white blood cell (WBC) counts and had elevated glucose, creatinine, troponin I, and NTpro- BNP levels but had decreased levels of hemoglobin. By multivariable analysis;age, NT-pro-BNP, WBC, troponin I, and creatinine levels were independently linked with the in-hospital mortality. After ROC evaluation, the ideal value of the NT-pro-BNP to predict the in-hospital mortality was found as 260 ng/L reflecting a sensitivity of 82% and a specificity of 93% (AUC:0.86;95% CI: 0.76-0.97). Conclusion: The current research clearly shows that the NT-proBNP levels are independently linked with the in-hospital mortality rates in subjects with COVID-19 pneumonia and without HF. Thus, we believe that this biomarker can be used as a valuable prognostic parameter in such cases.

Comparison of D-dimer level measured on the third day of hospitalization with D-dimer level in predicting in-hospital mortality in COVID-19 patients

Objective: The present study aimed to compare the value of D-dimer measured on the 3rd day of hospitalization with admission D-dimer level in predicting in-hospital mortality in coronavirus disease 2019 (COVID-19) cases. Method: In total, 231 patients with COVID-19 disease were included in the study. D-dimer levels were estimated using immunoturbidimetric assay with normal range of 0-500 μg/mL. In the current research, the primary outcome was the in-hospital mortality. Results: In the present research, 39 (16.8%) COVID-19 cases died during the index hospitalization. In a multivariable analysis;age, D-dimer (3rd day) (OR: 1.00, 95% CI: 1.00-1.00, p<0.001), WBC count, and creatinine were independent predictors of the in-hospital death for COVID-19 cases. The ideal value of D-dimer level on the 3rd day of hospitalization was 774 μq/mL (area under curve (AUC): 0.903, 95% CI: 0.836-0.968;p<0.01) with sensitivity of 83.2% and specificity of 83.6%. It was noted that D-dimer level on the 3rd day of hospitalization had a higher sensitivity (83.2% vs 67.6%, respectively) and AUC value than that of D-dimer level on admission (0.903 vs 0.799, respectively). Conclusion: The main finding in this investigation was that D-dimer elevation on the 3rd of hospitalization is more sensitive predictor of in-hospital mortality than D-dimer elevation on admission in COVID-19 patients. Even though further investigations are needed to forecast precise prognosis in patients with COVID-19 disease in terms of D-dimer levels, we believe that D-dimer levels on the 3rd day of hospitalization have an enhanced potential to be used as a prognostic marker in routine clinical practice.

COVID-19 AND COLORECTAL SURGERY: LESSONS LEARNED FROM FIRST CASES

Objective: This study aimed to examine the preoperative, perioperative, and postoperative colorectal surgery experience during the initial stage of the pandemic outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) later named COVID-19 disease in Turkey and to assess conditions and needs. Material and Method: Seven early cases of colorectal disease patients are described and lessons learned from these cases are reported. All patients' preoperative workup included two nasopharyngeal polymerase chain reaction (PCR) swabs for SARS-CoV-2 taken at a three-day interval preoperatively and a thorax computerized tomography scan taken on a preoperative day. Results: COVID-19 infection occurred before and after surgery despite all measures taken, including isolation. It became complicated to manage surgical complications such as stoma complication, surgical site infection, and small bowel obstruction. Nonetheless, while patients with underlying health conditions have a high mortality rate from COVID-19 infection, no death was observed in this small case series. Conclusion: Medical centers must be well organized to perform colorectal surgery under pandemic conditions. Patients may initially test negative or become positive for COVID-19 at any stage during this disease outbreak. Multidisciplinary teamwork with the infectious disease department and anesthetists can prevent mortality from COVID-19 infection during colorectal surgery and subsequent hospitalization.
