Item Hepatitis A susceptibility parallels high COVID-19 mortality(2021) Sarialioglu, Faik; Belen, Fatma Burcu; Hayran, Kadir Mutlu; 0000-0002-8257-810X; 0000-0002-9278-6703; 32718125; AAL-7766-2021Background/aim: COVID-19 has become the biggest health problem of this century. It has been hypothesized that immunity against hepatitis A virus (HAV) may provide protection from COVID19. Materials and methods: As of 10 June 2020, the infection had spread to 213 countries, with 7.3 million people infected and 413,733 dead. This data was combined with the World Health Organization susceptibility classification on the worldwide prevalence of HAV, and the relationship between HAV susceptibility and COVID-19 mortality were analyzed. Results: When the data from 213 countries were analyzed, it was found that there was a significant increasing trend in COVID-19 mortality rates by HAV susceptibility (P <0.001). Using a cut-off of 200/million population, the mortality risk associated with living in a more susceptible country (medium/high) was 27.8 times higher (95% CI for OR: 3.6-213.2) Conclusion: The results of this study showed that, despite confounding factors in different countries, hepatitis A susceptibility of the population may have been correlated with COVID-19 mortality. This observation needs to be confirmed by further studies.Item The Relationship Between COVID-19 Severity and Bacillus Calmette-Guerin (BCG)/ Mycobacterium Tuberculosis Exposure History in Healthcare Workers: A Multi-Center Study(2021) Torun, Serife; Ozkaya, Sevket; Sen, Nazan; Kanat, Fikret; Karaman, Irem; Yosunkaya, Sebnem; Sengoren Dikis, Ozlem; Asan, Ali; Aydogan Eroglu, Selma; Semih Atal, Sefa; Ayten, Omer; Aksel, Nimet; Ermis, Hilal; Ozcelik, Neslihan; Demirelli, Meryem; Kara, Iskender; Sumer, Sua; Marakoglu, Kamile; Uzer, Fatih; Uyar, Yasin; Cicek, Tuba; Unsal, Zuhal E.; Vatansev, Husamettin; Botan Yildirim, Berna; Kuruoglu, Tuba; Atilla, Aynur; Ersoy, Yasemin; Kandemir, Bahar; Durduran, Yasemin; Goksin Cihan, Fatma; Demirbas, Nur; Yildirim, Fatma; Tatar, Dursun; Akcay, M. Sule; 0000-0002-6530-6153; 0000-0002-8697-4919; 34014806; ABF-1652-2021The COVID-19 pandemic has brought countries' health services into sharp focus. It was drawn to our group's attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.Item Predictive Factors of Mortality in Granulomatosis with Polyangiitis: A Single-Center Study(2021) Tufan, Muge Aydin; Tekkarismaz, Nihan; 0000-0002-2686-9762; 0000-0001-7631-7395; 34870176; AAJ-9057-2021; AAD-9088-2021Objectives: The aim of this study was to identify predictors of mortality in granulomatosis with polyangiitis (GPA) patients and to seek the ways of improving survival in GPA patients. Patients and methods: Between January 2005 and June 2020, a total of 60 patients (26 males, 34 females; median age: 49 years; range, 19 to 75 years) who were diagnosed with GPA were retrospectively analyzed. Demographic, clinical, laboratory, and radiological findings of all patients were recorded. Survival rates were analyzed using the Kaplan-Meier plot. Results: The median follow-up was 36 months, and 10 (16.7%) patients died during the study period. Univariate analysis showed that the prognostic values were attributed to high serum creatinine levels (>2.1 mg/dL; p=0.01), proteinuria (p=0.01), dialysis-requiring renal damage at the time of diagnosis (p=0.01) or at any time during follow-up (p=0.01), low lymphocyte levels (p=0.01), hypoalbuminemia (p=0.04), absence of upper respiratory tract involvement (p=0.01), presence of lung involvement with cavitary lesions (p=0.01), high Birmingham Vascular Activity Score (p=0.02), and history of serious infection (p=0.01). In the multivariate analysis, the presence of renal damage requiring dialysis at any time during follow-up (relative risk [95% confidence interval]: 21 [4.1-18.3]; p=0.01) was found to be an independent predictor of mortality. Immunosuppressive drugs exerted no effect on mortality, and the most common causes of death were infections (50%). Conclusion: The presence of dialysis-requiring renal damage is the most important risk factor for mortality in GPA patients. These patients should be followed more closely and carefully to improve survival.Item An epidemiological study to define the recent clinical characteristics and outcomes of infective endocarditis in southern Turkey(2021) Acibuca, Aynur; Yilmaz, Mustafa; Okar, Sefa; Kursun, Ebru; Acilar, Onur; Tekin, Abdullah; Demiroglu, Yusuf Ziya; Muderrisoglu, Ibrahim Haldun; 0000-0002-9866-2197; 0000-0002-5658-870X; 33830167; AAZ-9711-2021; ABD-7304-2021Introduction: The aim of this study was to characterise the recent features of patients with infective endocarditis (IE) at one referral centre in southern Turkey, in order to be able to identify the high-risk subgroup and revise preventative measures and management strategies. Methods: Medical records of patients 18 years and older, who had been diagnosed with IE according to the Duke criteria between January 2009 and October 2019, were retrospectively evaluated in a referral general hospital. Results: The total of 139 IE cases comprised 59.7% males and 40.3% females, with a mean age of 55 +/- 16 years. The most encountered symptom was fever (55.4%) and the mitral valve (54%) was the most frequently involved. The most common causative micro-organisms were coagulase-negative staphylococci (30.2%). The in-hospital mortality rate was 30.2%, with congestive heart failure, chronic renal disease and chronic dialysis found to be significantly associated with in-hospital mortality. Conclusion: The study results demonstrate the recent epidemiological features of IE in southern Turkey that are important for clinicians to manage diagnostic and therapeutic processes successfully. Older age, the predominance of staphylococci and higher surgery rates are consistent with the changing trends of IE in some parts the world.Item Neutrophil to lymphocyte ratio, stroke severity and short term clinical outcomes in acute ischemic stroke(2021) Iyigundogdu, Ilkin; Derle, Eda; Kibaroglu, Seda; Can, Ufuk; 0000-0001-7860-040X; 0000-0002-3964-268X; AAJ-2053-2021; AAJ-2956-2021Background: Neutrophil to lymphocyte ratio is an easily evaluated systemic inflammation indicator. However, there are limited reports on neutrophil to lymphocyte ratio and functional outcome in ischemic stroke. In this study, we aimed to evaluate the association of neutrophil to lymphocyte ratio and stroke severity, short term functional outcomes and mortality in patients with acute ischemic stroke. Methods: The clinical data of patients who were > 18 age-old and hospitalized with acute ischemic stroke in Baskent University Hospital, Ankara, Turkey between January 2018 and May 2019 were studied retrospectively. Neutrophil to lymphocyte ratio were measured. The neutrophil to lymphocyte ratio and National Institute of Health Stroke Scale (NIHSS) score at admission, mortality during hospitalization and Modified Rankin Scale (mRS) score at discharge of the patients with acute ischemic stroke were correlated. Results: Among the acute ischemic stroke patients due to the exclusion criteria, the data of 134 patients were evaluated. Median age of the patients were 76 +/- 12.5 years and 82 patients (61.2%) were male. The median NIHSS scores of the patients at admission was 5 +/- 4.5. Mortality during the hospitalization was seen in 8 patients (6%). The median neutrophil to lymphocyte ratio value of the patients at admission were found to be 2.6 +/- 3.4. Neutrophil to lymphocyte ratio and NIHSS scores of the patients at admission, duration of the hospitalization, mRS scores at discharge and mortality during hospitalization were found to be positively correlated. Conclusion: Neutrophil to lymphocyte ratio is a simple and easily measured marker and can be used as a potential indicator for prognosis in acute ischemic stroke. However further prospective multicenter investigations are required to confirm the role of neutrophil to lymphocyte ratio for predicting the prognosis in acute ischemic stroke patients.Item Effects of personality traits on severity of sepsis(2021) Pehlivanlar Kucuk, Mehtap; Kucuk, Ahmet Oguzhan; Komurcu, Ozgur; Dikmen, Yalim; Kadioglu, Mustafa; Uzan, Cagdas Alp; Ergin Ozcan, Perihan; Orhun, Gunseli; Unal Akdemir, Neslihan; Eroglu, Ahmet; Ilyas, Yasir; Zeyneloglu, Pinar; Sahinturk, Helin; Dai Ozcengiz, Dilek; Firat, Ahmet; Aydin, Davut; Ozlu, Tevfik; Pehlivanlar, Aysegul; Kirakli, Cenk; Acar Cinleti, Burcu; Gok, Funda; Yosunkaya, Alper; Aktas, Murat; Ozturk, Cagatay Erman; Ulger, Fatma; 0000-0003-0159-4771; 34581156; AAJ-1419-2021Introduction: The aim of this study was to reveal the effect of the individual's lifestyle and personality traits on the disease process in patients with sepsis and to have clinical predictions about these patients. Materials and Methods: The study was planned as a multi-center, prospective, observational study after obtaining the approval of the local ethics committee. Patients were hospitalized in different intensive care units. Besides demographics and personal characteristics of patients, laboratory data, length of hospital and ICU stay, and mortality was recorded. Two hundred and fifty-nine patients were followed up in 11 different intensive care units. Mortality rates, morbidities, blood analyses, and personality traits were evaluated as primary outcomes. Results: Of the 259 patients followed up, mortality rates were significantly higher in men than in women (p=0.008). No significant difference was found between the patients' daily activity, tea and coffee consumption, reading habits, smoking habits, blood groups, atopy histories and mortality rates. Examining the personal traits, it was seen that 90 people had A-type personality structure and 51 (56.7%) of them died with higher mortality rate compared to type B (p=0.038). There was no difference between personalities, in concomitant ARDS occurrence, need for sedation and renal replacement therapies. Conclusion: Among individuals diagnosed with sepsis/septic shock, mortality increased significantly in patients with A-type personality trait compared to other personality traits. These results showed that personal traits may be useful in predicting the severity of disease and mortality in patients with sepsis/septic shock.Item Evaluation of Clinical Symptoms, Laboratory Findings, Radiological Characteristics, and Treatments of Adult Patients with Severe COVID-19 Pneumonia(2021) Kurekci, Yesim; Gumus, Hatice Hale; Ezirmik, Elif; 0000-0001-9071-9606; AAJ-2108-2021Introduction: In this study, it was aimed to retrospectively evaluate the clinical course, laboratory findings and radiological features of patients with severe Coronavirus disease-2019 (COVID-19) pneumonia in a 200-bed secondary state hospital. Materials and Methods: Male and non-pregnant female patients older than 18 years who were hospitalized with the diagnosis of COVID-19 pneumonia between 01.04.2020-01.07.2020 were included in our study. Severe pneumonia was defined as the presence of tachypnea (>30 breaths/ min) and/or hypoxia (SpO2 <90% room air) and/or bilateral diffuse ground-glass infiltrations. Conformity of continuous data to normal distribution was evaluated with Kolmogorov-Smirnov and Shapiro-Wilk tests. In the analysis of the relationship between laboratory parameters and mortality, independent groups t-test was used for parametric data and Mann-Whitney U test was used for non-parametric data. Results: Sixty two (60.8%) of the patients were male, with a mean age of 60.2 +/- 16.1 years (n=102). Of the study group 76.5% had at least one or more comorbid diseases. The most common comorbidities were hypertension (60.3%), diabetes mellitus (42.3%) and coronary artery disease (26.9%). The most common symptoms observed in patients at the time of admission were cough (n=63, 61.8%), dyspnea (n=57, 55.9%), fever (n=33, 32.4%) and malaise (n=22, 21.6%). Severe acute respiratory syndrome-Coronavirus-2 polymerase chain reaction test was positive in 68% (n=70) of the patients. Blood culture was taken from 42.3% of the patients who were admitted with the complaint of fever and there was no detected culture growth. During the hospitalization period, the rate of patients who received any of the antibiotic treatments including azithromycin, clarithromycin, moxifloxacin was 90.2% and 66.7% (n=68) of them were treated with azithromycin. Of the patients 42.2% (n=43) required treatment in the intensive care unit. A favorable clinical response was observed in 74.5% (n=77) of the patients and nine of these patients were discharged with partial recovery and recommendation for home oxygen support therapy. The mortality rate was 24.5% (n=25). The mean of lactate dehydrogenase level and the mean urea level were higher in the group with mortality (p <= 0.001). Conclusion: Despite the low rates of bacterial coinfection and/or secondary bacterial infection in COVID-19, frequently given antibiotic treatments contribute to the problem of antimicrobial resistance, creating a serious public health problem and causing an economic burden. Large-scale randomized controlled trials are required for treatment protocols of which potential benefits have not yet been proven.Item Prognostic value of MELD-XI score in patients referring to the emergency department with acute ST elevation myocardial infarction(2020) Celik, Olgun; Ciftci, Orcun; Mudderisoglu, Ibrahim Haldun; 0000-0001-8926-9142; 0000-0002-7190-5443; W-5233-2018; AAD-5477-2021Objective: We aimed to evaluate Model for End-stage Liver Disease excluding international normalized ratio (MELD-XI) score for prediction of 30-day in-hospital mortality in a cohort of patients with ST elevation myocardial infarction. Methods: The medical records of a total of 256 patients admitted with ST elevation myocardial infarction to the emergency department between January 2015 and January 2019 were retrospectively reviewed. A total of 111 patients were found eligible for the study. MELD-XI score was analyzed and compared on the basis of survival status. Results: A total of 111 patients with a mean age of 62.5 +/- 2.55 years were included in the study. In total, 81% (n = 90) of the patients were male and 19% (n = 21) were female. The mean MELD-XI score of the patients was 10.1 +/- 1.1. A total of 12 patients (12.9%) died within 30 days after hospitalization. The median MELD-XI score of the patients who died in the hospital was significantly higher than the patients survived (11.0 (10.5-11.6) vs 9.5 (9.4-13.8); p < 0.01). However, Gensini score was not significantly different between the surviving and deceased patients (p > 0.05). MELD-XI score was significantly correlated to left ventricular ejection fraction (r = -232, p < 0.01), and both parameters and age were significant independent predictors of in-hospital mortality (odds ratio: 1.73, 95% confidence interval: 1.25-2.39, p < 0.05; odds ratio: 0.89, 95% confidence interval: 0.81-0.99, p < 0.05; and odds ratio: 1.07, 95% confidence interval: 0.99-1.15, p < 0.05, respectively). A MELD-XI cut-off point of 10 had a sensitivity of 100% and a specificity of 78.8% for in-hospital mortality (area under receiver operating characteristics curve: 0.92, 95% confidence interval: 0.87-0.97, p < 0.05). A survival analysis based on a MELD-XI threshold of 10 revealed that the patients in the high-MELD-XI group had a significantly worse in-hospital survival (log rank test p < 0.001). Conclusion: MELD-XI score is a useful tool for in-hospital mortality prediction in patients referring to emergency medicine with acute ST elevation myocardial infarction.
