Abstract
OBJECTIVE The first decision to be made in the case of community-acquired pneumonia (CAP) is whether hospitalization of the patient is mandatory. In this study, we aimed to investigate whether the addition of oxygenation parameters to CURB-65 has diagnostic value in predicting mortality in CAP. PATIENTS AND METHODS A total of 903 CAP patients were included in the study. Patients with a CURB-65 score of 0 and 1 were classified as Group 1 and patients with a CURB-65 score of 2 or more were classified as Group 2. The prediction of mortality through Pneumonia Severity Index (PSI), CURB-65 and CURBS-65/CURBP-65 with the addition of SaO2 and PaO2 values; hence the four different models, was compared among all patient groups. RESULTS As a result, 3.3% of the cases in Group 1 and 12.7% of the cases in Group 2 died. In both CURB-65 groups, it was noted that the frequency of patients with SaO2 <90% was significantly higher in the dead group than in the alive patient group (p=0.009 and p=0.001, respectively). In the univariate analysis, PaO2<60, and SaO2<90 were significantly associated with mortality. Model 2 (CURBS-65) and Model 3 (CURBP- 65) were examined, SaO2<90 (OR 2.08) was found to have an effect on death. In predicting mortality by the receiver operating characteristics (ROC) analysis, it was understood that the CURBS-65 score had a slightly higher area under the curve (AUC) value than CURB-65. CONCLUSIONS As a result, it has been shown that the use of CURBS-65 scoring instead of CURB-65 clinical scoring may be more useful in predicting mortality.

Abstract
Crimean-Congo haemorrhagic fever (CCHF) is a severe human infection which can lead to fatal consequences. Acute CCHF patients were previously shown to exhibit frequencies of regulatory T-cell (Treg) but lower Treg-mediated suppressive activities than the healthy counterparts. This study aims is to investigate the phosphorylation levels of Foxp3 protein (master regulator of Treg cells) in CCHF patients. Blood samples collected from 18 CCHF patients and nine healthy volunteers were used to isolate peripheral blood mononuclear cells (PBMCs). Total and phosphorylated Foxp3 expression levels in the isolated PBMC samples were monitored by western blot and quantified using ImageJ software. Total Foxp3 expression levels in CCHF patients displayed decreasing trend, but not significantly. In contrast, significantly lower expression levels of phosphorylated Foxp3 were reported in CCHF patients. Our results suggest a possible association between Foxp3 dephosphorylation and CCHF pathogenesis. Nevertheless, more studies are required to evaluate the effect of Foxp3 dephosphorylation on Treg function, which would not only help to enlighten the CCHF pathogenesis but also contribute to the development of effective treatment strategies.

Abstract
Leptospirosis can present with severe cases such as polymyositis, peripheral neuropathy, and rarely, Guillain-Barré Syndrome (GBS). This paper reports a case who presented with dysarthria and GBS. A female patient presented with complaints of weakness, dizziness, diarrhea, and dysarthric. Her assessments included muscle strength globally 4/5 and deep tendon reflexes as hypoactive. An electromyographic examination was performed with the increase of weakness in the lower extremities, which indicated findings compatible with GBS. Antibodies against Leptospira biflexa serovar Patoc 1 at 1/400 titer were detected in the microscopic agglutination test (MAT). Neurological involvement in leptospirosis cases can range from meningoencephalitis to GBS.

Abstract
Objective While the coronavirus disease 2019 (COVID-19) pandemic was continuing at full speed, patients with Crimean-Congo hemorrhagic fever (CCHF), which is endemic in our region, apply to the emergency department simultaneously. The presence of computed tomography (CT) lesions suggesting COVID-19 in some CCHF patients has brought to our mind the question of whether there is CCHF lung involvement even though respiratory symptoms are not at the forefront. Methods In this study, the findings of chest CT, demographic data and clinical symptoms of cases who had thorax tomography scan with suspicion of COVID-19 in the emergency department in the spring and summer of 2020 and were diagnosed with CCHF as a result of the evaluation and followed up in our clinic were compared with the findings of COVID-19 cases that were hospitalized and treated in the same period. Results Seventy-seven COVID-19 and 25 CCHF cases were included in the study. Myalgia, headache, diarrhea, nausea and vomiting were significantly higher in CCHF patients ( p<0.05). Cough was significantly more common in COVID-19 patients ( p=0.034). Ground-glass opacity (GGO) was the most common tomography finding in CCHF, and cases without lung involvement were significantly higher (p=0.001). GGO, consolidation, vascularization, atelectasis band, reverse halo, air-bubble, nodule were significantly high in COVID-19 patients. Conclusion During the epidemic period, no pathological finding was found in thoracic CT in most of the CCHF cases, and the presence of involvement in the lung tomography in cases with similar clinical and laboratory findings should primarily suggest the diagnosis of COVID-19.

Abstract
OBJECTIVE To evaluate the rate of pneumococcal pneumonia (PP) among patients with community-acquired pneumonia (CAP) in Turkey and to investigate and compare features of PP and non-PP CAP patients. MATERIAL AND METHODS This multicenter, non-interventional, prospective, observational study included adult CAP patients (age ≥ 18 years). Diagnosis of PP was based on the presence of at least 1 positive laboratory test result for Streptococcus pneumoniae (blood culture or sputum culture or urinary antigen test [UAT]) in patients with radiographic findings of pneumonia. RESULTS Four hundred sixty-five patients were diagnosed with CAP, of whom 59 (12.7%) had PP. The most common comorbidity was chronic obstructive pulmonary disease (30.1%). The mean age, smoking history, presence of chronic neurological disease, and CURB-65 score were significantly higher in PP patients, when compared to non-PP patients. In PP patients, 84.8% were diagnosed based ony on the UAT. The overall rate of PP patients among CAP was calculated as 22.8% considering the UAT sensitivity ratio of 63% (95% confidence interval: 45-81). The rate of intensive care treatment was higher in PP patients (P = .007). While no PP patients were vaccinated for pneumococcus, 3.8% of the non-PP patients were vaccinated (P = .235). Antibiotic use in the preceding 48 hours was higher in the non-PP group than in the PP group (31.8% vs. 11.1%, P = .002). The CURB-65 score and the rate of patients requiring inpatient treatment according to this score were higher in the PP group. CONCLUSION The facts that PP patients were older and required intensive care treatment more frequently as compared to non-PP patients underline the burden of PP.

Abstract
Background Studies have shown, ambient temperature can affect the transmission and survival of coronaviruses. This study aimed to determine whether the number of COVID-19 cases and 14-day fatality rates (FR) in Berlin are associated with temperature. Methods Within the scope of this study, a total of 240 days of Berlin belonging to the dates 28.08.20- 24.04.21 were examined. Daily highest temperature, lowest temperature, daily average temperature, number of daily cases, number of deaths were accessed free from the berlin.de and weather.com site. In addition, the incubation period of COVID-19 was assumed to be 14 days, and the fatality rates of 14 days and the average temperatures of these days were calculated. The relationship between the data was evaluated with the Spearman correlation test. Results When the 240 days are examined, the average daily temperature varies between -7.5- 23.5 °C, the fatality rates of 14 days vary between 0- 7,3%. The period with the highest fatality rate of 14 days is between 29.1.21-11.2.21 (FR = 7.3%) and the average temperature of this period (-1.8 °C) is the 14 days with the lowest average temperature. Very strongly negative relationship (r = -0.920; p < 0.001) was determined between FR and 14-day average temperature. It was noted that as the daily temperature decreased, the number of deaths per day (r = -0.695; p < 0.001) and the number of daily cases (r = -0.296; p < 0.001) increased. 1 °C decrease in temperature was associated with an increase in daily new deaths by 1.29 (B = -1.29, 95% CI: -1.55, -0.1.09; p < 0.001, Adj. R2 = 0.3). Conclusions Our analysis results showed that the number of COVID-19 daily cases and 14-day fatality rate increased with a low temperature in the Berlin sample. Key messages Temperature showed a negative correlation between COVID-19 fatality rate. Further evaluation may be required globally with more data to determine temperature and COVID-19 cases.

Abstract
To describe the change in the epidemiology of health care-associated infections (HAI), resistance and predictors of fatality we conducted a nationwide study in 24 hospitals between 2015 and 2018. The 30-day fatality rate was 22% in 2015 and increased to 25% in 2018. In BSI, a significant increasing trend was observed for Candida and Enterococcus. The highest rate of 30-day fatality was detected among the patients with pneumonia (32%). In pneumonia, Pseudomonas infections increased in 2018. Colistin resistance increased and significantly associated with 30-day fatality in Pseudomonas infections. Among S. aureus methicillin, resistance increased from 31 to 41%.

Abstract
IntroductionCrimean-Congo haemorrhagic fever (CCHF) is a tick-borne disease in Africa, Asia, the Balkan peninsula, the south-east of Europe and the Middle East, with mortality rates of 3-30%. Transmission can also occur through contact with infected animals or humans.AimThis observational, prospective case series aimed to investigate detectable viral genomic RNA in whole-body fluids and antibody dynamics in consecutive daily samples of patients diagnosed with CCHF until discharge from hospital.MethodsWe tested 18 patients and 824 swabs and sera with RT-PCR and 125 serum samples serologically.ResultsThe longest duration until clearance of viral RNA was 18 days from serum collection and 18, 15, 13, 19 and 17 days, respectively, from nasal, oral, genital (urethral or vaginal) and faecal swab, and urine. In seven patients, viral load decreased in serum at the same time as it increased in urine or persisted at the same logarithmic values. Despite clearance in serum, viral RNA was detected in faeces and genital swabs in two and three patients, respectively. Viral clearance from body fluids occurred earlier than from serum in eight patients on ribavirin treatment. The shortest seroconversion time was 3 days after symptom onset for IgM and IgG. Seroconversion of IgG occurred until Day 14 of symptoms.ConclusionWe report persistence of viral RNA in urine, faeces and genital swabs despite serum clearance. This may indicate a need for extending isolation precautions, re-evaluating discharge criteria and transmission risk after discharge, and considering oral swabs as a less invasive diagnostic alternative.

Abstract
Background:Interstitial lung disease (ILD) is a common morbidity and mortalitiy reason for connective tissue disorders (CTD). Data related to treatment options in the literature is limitedObjectives:To describe the role of azathiopurine (AZA) in the first line treatment of connective tissue disease related interstitial lung disease CTD-ILD, comparing with cyclophosphamide (CYC)Methods:Between 2009 and 2019 all interstitial lung disease patients admitting rheumatology or pulmonology department were retrospectively evaluated. Among those patients,as an first line regimen treated with either azathiopurine or cyclophospamide were included. Primary end point was FVC percentage change at 6th month.Results:Among 328 CTD-ILD, 57 patients had AZA treat and 79 patients had CYC for the first line treatment. Patients treated with AZA tend to have limited disease and older age. CYC treatment had a mean of 2,41% increase in FVC but in AZA -1,44% decrease in FVC predicted (p:0,041) 5 major CTD groups were defined (systemic sclerosis (SSc), rheumatoid arthritis (RA), primer sjögren syndrome (pSS), dermatomyositis/ polimyositis (PM/DM), autoimmune features of intestitial lung disease (IPAF)). AZA had similar efficacy in, PM/DM and IPAF groups but worse outcome in SSc, RA and pSS compared to CYC.Conclusion:AZA treatment might be an option patients with limited disease extent and the diagnosis of PM/DM or IPAF.

Abstract
Background:Colchicine is the mainstay of treatment in FMF. However, in daily practice it is not easy to maintain effective colchicine doses in substantial number of patients, due to its side effects.Objectives:It was aimed to investigate prevalence and risk factors for colchicine side effects that limit optimal drug dosing and permanent discontinuation.Methods:All patients were recruited from “FMF in Central Anatolia” (FiCA) cohort, 915 adult subjects with minimum follow up time of 6 months and had compliance of treatment were included. Demographic and anthropometric data, FMF disease characteristics, disease severity, complications and treatment features were recorded on a web based registry. Prevalence of colchicine intolerance and characteristics of intolerant patients were analyzed.Results:Effective colchicine doses cannot be maintained in 172 (18.7%) subjects. Main side effects that limit optimal dosing were as follows; diarrhea in 99 (10.8%), elevation in transaminases in 54 (5.9%), leukopenia in 10 (%1.1), renal impairment in 14 (1.3%), myopathy in 5 (0.5%) and allergic skin reaction in two. Colchicine had to be permanently ceased in 18 (2%) patients because of serious toxicity. Male gender and obesity were found to be associated with liver toxicity and having normal body weight was associated with diarrhea. Chronic inflammation and proteinuria were more common in colchicine intolerant patients and they had reported more frequent attacks compared to those tolerating optimal doses.Conclusion:Colchicine intolerance is an important problem in daily clinical practice, mainly due to diarrhea and liver toxicity. Suboptimal colchicine dosing associated with complications.References:[1] Sönmez, H.E., E.D. Batu, and S.

Abstract
Background:Cyclophosphamide (CYC) had a good response rates when used as an induction regimen for the treatment of connective tissue related interstitial lung disease (CTD-ILD). But the safety profile of CYC necessitates the usage of a second line treatment for maintenanceObjectives:To compare the effect of mycophonetil (MMF) and azatiyopurin (AZA) for maintanance therapy following cyclophsphomide treatment in CTD-ILDMethods:Between 2009 and 2019 all interstitial lung disease patients admitting rheumatology or pulmonology department were retrospectively evaluated and patients treated with cyclophospamide as an induction regimen and having not progression were selected. Among those, as a second line regimen treated with MMF or AZA were included. Primary end point was treatment responses at 6th monthsResults:68 patients treated with CYC for the first line treatment. 46 patients treated with either MMF (n:22) or AZA (n:24) for the maintenance. Scleroderma patients were the largest group and consituted 63% of the population. MMF group had worse FVC values and more involvement in lung paranchyme at the begining of the treatment. In univariate analysis FVC (lt) values and lung involvement (%) on HRCT at the start of the treatment, and disease subtype were associated significantly with treatment responses.After adjusted with these factors, in multivariate analysis, AZA treatment was associated with the increased risk of progression (odds ratio 5,8, 95% CI 1,061-31,09) as compared with MMF treatmentConclusion:MMF had better results compared to AZA in the treatment of CTD-ILD,after the usage of CYC treatment.References:[1]Barnes, H., et al.,Cyclophosphamide for connective tissue disease-associated interstitial lung disease.Cochrane Database Syst Rev, 2018.1(1): p.

Abstract
Crimean-Congo hemorrhagic fever (CCHF) is fatal. Therefore, it is very important to use an inexpensive, easily accessible, quick and accurate screening index based on clinical signs and laboratory parameters to identify patients suspected of having CCHF. Laboratory test results on the day of hospitalization for 268 inpatients suspected of having CCHF were used to calculate the laboratory section of the Hitit Index, while 65 of these were also monitored daily during their hospital stay to develop the clinical section of the Hitit Index. Two-hundred CCHF-negative outpatients were also evaluated. One-hundred and forty-nine inpatients were CCHF-positive and 119 inpatients were CCHF-negative. The Hitit Index is 5.6 - (5.3*lymphocyte) - (0.02*fibrinogen) - (12*direct bilirubin) + (0.04*AST) + (0.32*hematocrit) - (0.5*neutrophil) - (0.07*CKD-EPI) - (0.001*CK) ± conjunctival hyperemia (+1.5 in conjunctival hyperemia presence and -1.5 in conjunctival hyperemia absence). In 65 inpatients monitored daily, Hitit Index results for CCHF-positive and negative inpatients were 6.10(1.90-12.30) and -5.35(-8.83- -1.95), while CCHF-negative outpatients were -10.99(-15.64- -6.95) (P < 0.001), respectively. On hospitalization day, just one inpatient was false-negative in 27 CCHF-positive inpatients, while four were false-positive among 38 CCHF-negative inpatients using the Hitit Index. After 24 h, just one inpatient was diagnosed falsely among 27 CCHF-positive and 38 CCHF-negative inpatients, and there was no change after 48 h. Management of patients living in endemic regions suspected of having CCHF could be achieved within minutes using the Hitit Index. Patients with Hitit Index less than zero can be monitored as outpatients, while patients with Hitit Index results above zero must be hospitalized in infectious diseases wards. This study was not registered since it was retrospective.

Abstract
Introduction Influenza subtypes vary by clinical, radiological, and prognostic courses and may go along with viral pneumonia. We aimed to identify clinical, radiological, and prognostic aspects of influenza epidemic during years 2016-2017. Materials and Methods Influenza cases reported to the Public Health Directorate in our city was assessed retrospectively. Clinical, radiological, and prognostic parameters were compared based on influenza subtypes. Result We analyzed samples from 197 cases with suspected influenza. Mean age of the subjects was 51.17 ± 26.74. We found influenza A/H1N1, influenza A/H3N2, and influenza B in 59 (30.0%), 29 (14.7%), and 3 (1.5%) cases, respectively. Comorbidity was present in 48 (24.4%) cases. Most common radiological finding was interstitial pattern. Seventy-one and 79 per cent of H1N1 and H3N2 cases were influenza pneumonia, respectively. The prevalence of overall mortality was 5.5% with a predominance in H1N1 over H3N2. Influenza vaccination had been performed in 6.8% and 3.4% of H1N1 and H3N2 cases, respectively. We detected no mortality in any vaccinated patient. We identified 6 pregnant women, 2 of which ended up with preterm birth, and another one with abortion. Conclusions Often manifested as lower respiratory tract infection, influenza may cause epidemics with increased mortality rate. Influenza should be suspected when interstitial pattern was seen on radiological images. H1N1 cases course worse. Since the prognosis is better in vaccinated patients, seasonal influenza vaccination among the community needs to be elevated. In addition, protective measures like vaccination should be taken in pregnancy to avoid preterm delivery or abortion.

Abstract
Background Tick-borne diseases are increasing all over the word, including Turkey. The aim of this study was to determine the bacterial and protozoan vector-borne pathogens in ticks infesting humans in the Corum province of Turkey. Methodology/Principal findings From March to November 2014 a total of 322 ticks were collected from patients who attended the local hospitals with tick bites. Ticks were screened by real time-PCR and PCR, and obtained amplicons were sequenced. The dedected tick was belonging to the genus Hyalomma, Haemaphysalis, Rhipicephalus, Dermacentor and Ixodes. A total of 17 microorganism species were identified in ticks. The most prevalent Rickettsia spp. were: R. aeschlimannii (19.5%), R. slovaca (4.5%), R. raoultii (2.2%), R. hoogstraalii (1.9%), R. sibirica subsp. mongolitimonae (1.2%), R. monacensis (0.31%), and Rickettsia spp. (1.2%). In addition, the following pathogens were identified: Borrelia afzelii (0.31%), Anaplasma spp. (0.31%), Ehrlichia spp. (0.93%), Babesia microti (0.93%), Babesia ovis (0.31%), Babesia occultans (3.4%), Theileria spp. (1.6%), Hepatozoon felis (0.31%), Hepatozoon canis (0.31%), and Hemolivia mauritanica (2.1%). All samples were negative for Francisella tularensis, Coxiella burnetii, Bartonella spp., Toxoplasma gondii and Leishmania spp. Conclusions/Significance Ticks in Corum carry a large variety of human and zoonotic pathogens that were detected not only in known vectors, but showed a wider vector diversity. There is an increase in the prevalence of ticks infected with the spotted fever group and lymphangitis-associated rickettsiosis, while Ehrlichia spp. and Anaplasma spp. were reported for the first time from this region. B. microti was detected for the first time in Hyalomma marginatum infesting humans. The detection of B. occultans, B. ovis, Hepatozoon spp., Theileria spp. and Hemolivia mauritanica indicate the importance of these ticks as vectors of pathogens of veterinary importance, therefore patients with a tick infestation should be followed for a variety of pathogens with medical importance. Ticks are important vectors for different kind of pathogens, both of medical and veterinary importance, while tick-borne diseases (TBDs) are increasing all over the world. In Turkey, many important human and zoonotic TBDs such as, Lyme borreliosis, rickettsiosis, anaplasmosis, ehrlichiosis, tularemia, bartonellosis, babesiosis, theileriosis, and hepatozoonosis have been reported. Nonetheless, there is lack of research-based information concerning the epidemiology, ecology, and vector diversity of these tick-borne pathogens. In this study, we aimed to investigate broad-range bacterial and protozoan vector-borne pathogens by PCR/RT-PCR and sequencing, those ticks infesting humans in the Corum province. Spotted fever group rickettsiae and lymphangitis-associated rickettsiae, Borrelia afzelii, Anaplasma spp., Ehrlichia spp. were detected. Babesia microti was detected in Hyalomma marginatum infesting humans. Interestingly zoonotic pathogens like Babesia ovis, Babesia occultans, Theileria spp, Hepatozoon felis, Hepatozoon canis, and Hemolivia mauritanica were also detected, showing the role of ticks for diseases also of veterinary importance. This study provides important data for understanding the epidemiology of tick-borne pathogens and it is hoped that these results will challenge clinicians and veterinarians to unify their efforts in the management of TBDs.

Abstract
Crimean-Congo hemorrhagic fever (CCHF) is a severe human infection caused by CCHF virus (CCHFV). Today, although the literature on CCHF pathogenesis is still limited, it is thought to be associated with immunosuppression in the early phase of infection followed by pro-inflammatory immune response that may lead to fatal outcomes. The aim of this study is to investigate the role of regulatory T-cells (Treg cells) in the pathogenesis of CCHFV. Peripheral blood mononuclear cell samples collected from 14 acute CCHF patients with mild disease course and 13 healthy subjects were included in this study. Treg expression and functional levels were analyzed by flow cytometry. Treg cells were identified as CD4+CD25 + CD127dim cells, and their functional levels were compared by measuring their ability to suppress CD69 and CD154 expression by activated T-cells. The flow cytometry analysis revealed that total T-cell and helper T-cell levels did not vary between the two groups. In contrast, CCHF patients displayed higher Treg cell levels but lower Treg suppressive activities when compared with control subjects. This is the first study on the involvement of Treg cells in CCHF pathogenesis. Our results indicate that even though Treg cell levels are elevated during acute phase of CCHF infection, not all generated Treg cells has immunosuppressive capacity, and therefore may not represent 'true' Treg cell population. Future studies on the intrinsic mechanisms responsible for the reduced Treg inhibitory activities are required for further enlightening the CCHF pathogenesis, especially in the acute phase of the disease.

Abstract
INTRODUCTION The information of discharge criteria in patients with Crimean-Congo Hemorrhagic Fever (CCHF) is limited. In this study, we aimed to determine the clinical and laboratory parameters used in discharging the patients by the experienced centers. MATERIALS AND METHODS The study was done in 9 reference centers of CCHF from May 1, 2015 to December 1, 2015 and included laboratory-confirmed patients with CCHF. The study was prospective, observational and non-interventional. RESULTS The study included 260 patients. Mean age was 51.3 ± 16.3 years; 158 (60.8%) were male. Mean hospital stay was 7 ± 2.6 days. The decision of discharging was taken considering clinical and laboratory findings. On discharge, no patients had fever or hemorrhage. The patients were followed-up clinically and a repeat CCHF PCR was not studied. All centers considered the following criteria for discharge: no fever and hemorrhage, improvement in clinical findings and laboratory studies. For all patients except one, platelet count was >50,000/mm(3) and had a tendency to increase. Prothrombin time and international normalized ratio (INR) were normal in 258 (99.6%) and 254 (98.1%) patients respectively. Alanine aminotransferase (ALT) was either normal or not higher than 10-fold and had a tendency to decrease in 259 (99.6%) patients. ALT and aspartate aminotransferase (AST) levels were not taken as discharge criteria with priority. During 30 days following the discharge, complication, relapse, or secondary transmission were not reported. CONCLUSIONS The discharging practice of the centers based on clinical and laboratory parameters seems safe considering no complications, relapses, or secondary infection thereafter. Current discharge practice of the centers composed of no fever and hemorrhage, improvement in clinical findings, platelet count of either >100,000/mm(3) or >50,000/mm(3) with a tendency to increase, and normal bleeding tests can be used as the criteria of discharge.

Abstract
INTRODUCTION We aimed to determine clinical, laboratory and demographical characteristics of tularemia on admission to Emergency Department (ED). MATERIAL AND METHODS Medical data of 317 patients admitted to ED and subsequently hospitalized with suspected tularemia between January 1, 2011, and May 31, 2015, were collected. Patients were divided into 2 groups according to microagglutination test results, as tularemia (+) and tularemia (-). RESULTS Of the 317 patients involved, 49 were found to be tularemia (+) and 268 were tularemia (-). Mean age of the tularemia (+) patients was found to be higher than that of tularemia (-) patients. When compared to tularemia (-) patients, a significant portion of patients in tularemia (+) patients were elderly, living in rural areas and had contact with rodents. When clinical and laboratory findings of the 2 groups were compared, any statistical significance could not be determined. CONCLUSION Tularemia is a disease of elderly people living in rural areas. Contact with rodents also increases risk of tularemia in suspected patients.

Abstract
Crimean-Congo hemorrhagic fever (CCHF) is a viral zoonotic disease that is transmitted primarily through contact with ticks. Nosocomial cases and outbreaks of CCHF have been reported from many countries. Health care workers (HCWs) are at risk of exposure to CCHF. In our study, we evaluated seven HCWs' exposure to confirmed CCHF patients' infected blood and body fluids and prophylactic efficacy of the ribavirin on nosocomial transmission of CCHF retrospectively. Between 2007 and 2013, 150 CCHF cases were admitted to our clinic. During the follow-up of these patients, four doctors and three nurses had contact with infected blood and body fluids through needle stick injury, contact of skin and mucosal surfaces, and probable aerosolization. All of the index cases' diagnoses of CCHF were confirmed during the contact. Ribavirin prophylaxis was administered within 0.5-1 h in six out of seven cases. All of these cases' CCHF virus PCR results were negative. One physician had no contact with infected blood or body fluid, so ribavirin prophylaxis was not administered. The physician developed CCHF and diagnosis was confirmed. Although efficacy of ribavirin for prophylaxis is not clear and very few data exist on prophylactic usage of ribavirin, lack of clinical manifestations in our cases that were given ribavirin compared with the developed clinical manifestations in the physician may be explained by the prophylactic efficacy of the ribavirin.

Abstract
The objective of this study was to investigate the relationship between serum total thiol level and total oxidant status (TOS) and thrombocytopenia among patients with Crimean-Congo hemorrhagic fever (CCHF). Eighty-three subjects and 56 controls were enrolled in the study. Thiol levels were measured with the DTNB method and TOS was measured with the Erel's method among subjects and controls. Thiol levels were lower in subjects than controls and TOS levels were higher in subjects than controls. There was a significant correlation between total thiol levels and platelet counts (r = 0.84, p < 0.0001) among subjects. Further investigations are needed into the link between total thiol level and TOS and the pathogenesis of hemorrhage in CCHF.
