Publication Open Access Miliary Tuberculosis Induced Acute Liver Failure(HINDAWI LTD, 2015) BİLGİN, HÜSEYİN; Toptas, Tayfur; Ilhan, Birkan; Bilgin, Huseyin; Dincses, Elif; Ozdogan, Osman; Kaygusuz-Atagunduz, Isik; Odabasi, Zekaver; Korten, Volkan; Firatli-Tuglular, TulinHepatobiliary tuberculosis is uncommon even in endemic countries. It is associated with a high mortality and is even diagnosed early in the disease course. Acute liver failure (ALF) caused by tuberculosis bacilli has been reported in only a few reports. All previous cases have been diagnosed by postmortem examination. Time to antituberculosis treatment is very critical. In case of suggestive findings on clinical and radiologic examination, antituberculosis treatment should be initiated immediately. Drug use can be a challenge in patients with ALF. However, as long as the other possible causes of ALF can be excluded and hepatotoxic drugs were avoided during the early course of treatment, such a highly fatal presentation of tuberculosis can be treated safely. Here, we report a case of acute liver failure as a presentation of miliary tuberculosis. He was treated successfully with antituberculosis treatment.Publication Open Access Crimean-Congo Hemorrhagic Fever in Turkey(2004-08) KORTEN, VOLKAN; Karti, S.

METHODS A prospective clinical study in 4 different tertiary hospitals between 2008 and 2010 was conducted. Four hundred men with sterile urine who were to undergo a TRUSbx because of the suspicion of prostate cancer were included and followed for 14 days after biopsy. Rectal swab culture specimens were acquired immediately before the procedure. Demographic data, prophylaxis choice, quinolone or any other antibiotic consumption within the past 2 months, history of prostatitis, repeat biopsy, intensive care unit admission, hospitalization, urethral catheterization, diabetes mellitus (DM), and steroid usage were recorded. RESULTS ESBL carriage was detected in 19% of patients and quinolone use within the last 2 months; other antibiotic use within the last 2 months and DM were found to be significantly associated (P < .05). Symptomatic urinary tract infection (UTI) on the third day after biopsy was seen in 9% of patients and was associated with fluoroquinolone (FQ) consumption before biopsy. Although ESBL-PE carriage was associated with post-biopsy UTI symptoms, it was not found to be associated with post-biopsy symptomatic UTI. Urosepsis was seen in 2 patients (0.5%) after biopsy, and both the patients were ESBL-PE carriers. CONCLUSION The presence of ESBL-PE was associated with DM and FQ consumption before biopsy. ESBL-PE carriage was associated with a high rate of post-biopsy UTI symptoms requiring further elucidation; however, it was not associated with microbiologically proven infections. FQ consumption before TRUSbx was also associated with post-biopsy infections.

Some patients develop features of macrophage activation syndrome (MAS). Elevated levels of IL-6 were reported to be associated with severe disease, and anti-IL-6R tocilizumab has been shown to be effective in some patients. This retrospective multicenter case-control study aimed to evaluate the efficacy of tocilizumab in hospitalized COVID-19 patients, who received standard of care with or without tocilizumab. Primary outcome was the progression to intubation or death. PSMATCH (SAS) procedure was used to achieve exact propensity score (PS) matching. Data from 1289 patients were collected, and study population was reduced to 1073 based on inclusion-exclusion criteria. The composite outcome was observed more frequently in tocilizumab-users, but there was a significant imbalance between arms in all critical parameters. Primary analyses were carried out in 348 patients (174 in each arm) after exact PS matching according to gender, ferritin, and procalcitonin. Logistic regression models revealed that tocilizumab significantly reduced the intubation or death (OR 0.40, p = 0.0017). When intubation is considered alone, tocilizumab-users had > 60% reduction in odds of intubation. Multiple imputation approach, which increased the size of the matched patients up to 506, provided no significant difference between arms despite a similar trend for intubation alone group. Analysis of this retrospective cohort showed more frequent intubation or death in tocilizumab-users, but PS-matched analyses revealed significant results for supporting tocilizumab use overall in a subset of patients matched according to gender, ferritin and procalcitonin levels.Publication Open Access STREPTOCOCCUS BOVIS ENDOCARDITIS ASSOCIATED WITH RECTAL CARCINOMA AND ITS NEUROLOGICAL COMPLICATIONS CASE REPORT AND LITERATURE REVIEW(2006-04-15) KORTEN, VOLKAN; Abul, Yasin; Odabasi, Zekaver; Kodalli, Nihat; Oktay, Ahmet; Korten, VolkanPublication Open Access Liver stiffness is associated with disease severity and worse clinical scenarios in coronavirus disease 2019: A prospective transient elastography study(WILEY, 2021-09) KORTEN, VOLKAN; Demirtas, Coskun Ozer; Keklikkiran, Caglayan; Ergenc, Ilkay; Sengel, Buket Erturk; Eskidemir, Gunes; Cinel, Ismail; Odabasi, Zekaver; Korten, Volkan; Yilmaz, YusufBackground Pre-existing chronic liver disease is currently considered a poor prognostic factor for coronavirus disease 2019 (COVID-19). The present study aimed to investigate the association of liver stiffness measurement (LSM) with disease severity and clinical course of COVID-19. Methods We prospectively recruited consecutive hospitalised adult patients with COVID-19 in a 3-month period. Demographic, laboratory, clinical and vibration-controlled transient elastography (VCTE) features were recorded at entry, and all patients were prospectively followed-up. Severe liver fibrosis was defined as an LSM value higher than 9.6 kPA. Multivariate logistic regression analysis was performed to reveal factors associated with disease severity and outcomes. Results Out of 98 eligible patients with COVID-19, 12 (12.2%) had severe liver fibrosis. Patients with severe liver fibrosis had higher baseline disease severity (P = .022), more commonly required oxygen treatment at entry (P = .010), and had intensive-care unit (ICU) requirements during the 6 (1-39)-day median follow-up time (P = .017). The presence of severe liver fibrosis was independently associated with disease severity (odds ratio (OR): 7.685, 95% confidence interval (CI): 1.435-41.162, P = .017) and ICU requirement (OR: 46.656, 95% CI: 2.144-1015.090, P = .014). LSM was correlated with alanine aminotransferase levels (P = .005, r: 0.283), but not with other markers of acute hepatic injury or inflammation. Conclusion Initial VCTE application might help physicians identify patients who are more likely to have severe illness or worse clinical outcomes, in addition to other well-established clinical and laboratory factors. Further multicentre prospective studies are warranted to validate our results.Publication Open Access Impact of tocilizumab on clinical outcomes in severe COVID-19 patients and risk of secondary infection: A case-control study(MARMARA UNIV, FAC MEDICINE, 2021-05-25) ERTÜRK ŞENGEL, BUKET; Sengel, Buket Erturk; Ozel, Serra; Gul, Fethi; Ilgin, Can; Tigen, Elif Tukenmez; Altunal, Luftiye Nilsun; Kabadayi, Feyyaz; Sili, Uluhan; Aydin, Mehtap; Odabasi, Zekaver; Cinel, Ismail; Korten, VolkanObjective: This study aimed to identify the effect of tocilizumab (TCZ) on clinical outcomes in severe COVID-19 patients. Material and Methods: We included hospitalized COVID-19 patients with an initial WHO scale >= 4. We matched the patients with baseline characteristics by using propensity scores. Then, we selected patients with C-reactive protein levels above 30 and showing an upward trend. We assessed the effect of TCZ in patients on clinical outcomes by using Mann - Whitney U and Chi-square tests. Results: Of 200 patients who had an initial WHO scale >= 4, 42 (21%) were given it? in addition to standard of care (SOC). Twenty-five patients (50%) needed mechanical ventilation (MV) in the TCZ group, compared with 35 (21%) of 158 patients with SOC (p<0.01). Nineteen (45%) and 37 (23%) patients died in 30 days in these groups, respectively (p <0.01). The secondary infection rate was significantly higher in the TCZ group (p=0.004). However, no difference was observed in all these parameters in the propensity score-matched cohort (14 patients in ICZ and 14 in the SOC group) (p=0.45, 0.45, 1.0 respectively). Conclusions: Tocilizumab does not provide a beneficial effect on MV requirement and mortality in severe COVID-19, and it does not increase the risk of secondary bacterial infection.Publication Metadata only Outcomes of Fecal Carriage of Extended-spectrum b-Lactamase After Transrectal Ultrasound-guided Biopsy of the Prostate COMMENT Reply(ELSEVIER SCIENCE INC, 2014) ERTÜRK ŞENGEL, BUKET; Tigen, Elif Tukenmez; Tandogdu, Zafer; Ergonul, Onder; Altinkanat, Gulsen; Gunaydin, Bilal; Ozgen, Mahir; Sariguzel, Nevin; Sengel, Buket Erturk; Odabasi, Zekaver; Cek, Mete; Tokuc, Resit; Turkeri, Levent; Mulazimoglu, Lutfiye; Korten, VolkanPublication Open Access Application of CALL score for prediction of progression risk in patients with COVID‐19 at university hospital in Turkey(2021-10) ILGIN, CAN; Erturk Sengel, Buket; Tukenmez Tigen, Elif; Ilgin, Can; Basari, Tugce; Bedir, Merve; Odabasi, Zekaver; Korten, Volkan
