Introduction In this study, we aimed to investigate and compare the prognostic impacts of C-reactive protein (CRP), white blood cell (WBC) count, neutrophil (NEU)-to-lymphocyte (LYM) ratio (NLR), platelet-to-lymphocyte ratio (PLR), Red Cell Distribution Width (RDW) biomarkers in laboratory-confirmed COVID-19 cases as well as to explore the most useful diagnostic biomarkers and optimal cutoff values in COVID-19 patients. Methods A total of 233 patients were admitted to Emergency Department (ED) of XXXXXX University Hospital during two months (March–April 2020) and underwent Sars CoV-2 PCR (Polymerase Chain Reaction), complete blood count (CBC), and CRP tests in sequence due to complaints of COVID-19. The laboratory results and demographic findings were collected from the public health management system retrospectively. The patients with positive Sars CoV-2 PCR test along with hospitalization data were also recorded. Results The CRP ( p = 0.0001), lactate dehydrogenase (LDH) ( p = 0.038), PLR ( p = 0.0001) and NLR ( p = 0.001) remained significantly higher in the patients with positive Sars CoV-2 PCR test result. By contrast, eosinophil ( p = 0.0001), lymphocyte ( p = 0.0001), platelet levels ( p = 0.0001) were calculated as significantly higher in negative Sars CoV-2 patients. Conclusion In the light of the obtained results, the CRP, LDH, PLR and NLR levels remained significantly higher in COVID-19 positive patients, while eosinophil, lymphocyte, and platelet levels were significantly elevated in COVID-19 negative patients.

Introduction: Patients diagnosed with COVID-19 have presented to emergency departments (EDs) worldwide with a wide range of symptoms. In this study we reported the clinical, laboratory and radiological features of the cases diagnosed with COVID-19. Methods: This is a single-center, retrospective, descriptive, and observational study. The patients who have admitted to ED between March 11 and May 31, 2020 and diagnosed COVID-19 infection. Results: 130 (73 male and 57 female) patients with COVID-19 polymerase chain reaction (PCR) positive test were included in the study. The average age of the study group was calculated as 52.63 ± 17.95 year. While 15.4% of the patients were asymptomatic, the most common symptom was identified as cough (46.2%), followed by dyspnea (23.1%), fever (17.7%). The computed tomography (CT) severity scores proved significantly higher in the patients with hypertension and coronary artery disease (CAD) than in those without these diseases (p = 0.010 and p = 0.042, respectively). The moderate positive correlation between serum ferritin level and CT severity score is another finding worth noting (rho = 0.530 and p = 0.0001). In a similar vein, the high level of Ddimer in the CT-positive group and its positive moderate correlation with CT severity (rho = 0.375 and p = 0.0001). Conclusion:In our study, serum ferritin and D-dimer levels were observed to be high in the CT-positive group and have moderate positive correlation with CT severity. We thus argue that D-dimer and ferritin levels measured at the time of admission to the ED can be taken into consideration to predict radiological severity.

Objective: We aimed to evaluate the demographic, clinical, laboratory and electrophysiological findings of patients with inpatient Guillain-Barré syndrome in our clinics and to investigate the effect of these parameters on the prognosis of the disease. Materials and Methods: Between January 2014 and April 2018, file records of patients admitted to our clinics with the diagnosis of Guillain-Barré syndrome were retrospectively reviewed. Demographic characteristics, clinical, laboratory and electrophysiological findings of the patients at the time of admission were recorded. Patients were clinically graded according to the Hughes classification at the time of admission and on the 3 rd month after discharge. Results: In the study, 25 of the 51 patients were male (49%) and 26 were female (51%) and the mean age was 54.21±17.32 years. According to clinical and electrophysiologic diagnosis, 34 patients (66.7%) had acute inflammatory demyelinating polyradiculoneuropathy, 9 patients (17.6%) had acute motor axonal neuropathy, 6 patients (11.8%) had acute motor sensory axonal neuropathy and 2 patients (3.9%) had Miller Fisher syndrome. According to Hughes scoring on the 3 rd month after discharge, 31 patients (60.8%) had in good prognosis (Hughes score ≤2) and 20 patients (39.2%) had in poor prognosis group (Hughes score >2). In the comparison between the two groups according to clinical, demographic, and laboratory parameters, older age (≥50), high Hughes score at admission, weakness in extremities as first complaint, the presence of complications, need for mechanical ventilation and presence of gastroenteritis as a leading infection were evaluated as prognostic factors. Conclusion: The most common variant of Guillain-Barré syndrome in our study was acute inflammatory demyelinating polyradiculoneuropathy. Older age (≥50), high Hughes score at admission, weakness in extremities as the first symptom, presence of complications, need for mechanical ventilation, and presence of gastroenteritis as a precursor infection were poor prognostic factors.
