Item Continuous insulin therapy versus apheresis in patients with hypertriglyceridemia-associated pancreatitis(2022) Araz, Filiz; Bakiner, Okan Sefa; Bagir, Gulay Simsek; Soydas, Baris; Ozer, Birol; Kozanoglu, Ilknur; 0000-0003-0780-5680; 0000-0002-5268-1210; 33323759; AAJ-9184-2021; AAE-1241-2021Background The optimal treatment modality for lowering the triglyceride level in patients with hypertriglyceridemia (HTG)-associated acute pancreatitis is unknown. We evaluated the efficacy of continuous insulin infusion and apheresis procedures as triglyceride-lowering therapy. Materials and methods Clinical, demographic, and laboratory data were retrospectively evaluated for patients with HTG-associated pancreatitis who received continuous insulin infusion or apheresis in a single tertiary center. The endpoints were modality effectiveness and clinical outcomes. Results The study included 48 patients (mean age, 40.4 +/- 9.9 years). Apheresis and insulin infusion were performed in 19 and 29 patients, respectively, in the first 24 h of hospital admission. Apheresis procedures included therapeutic plasma exchange in 10 patients and double filtration plasmapheresis in nine patients. Baseline mean triglyceride level was higher in the apheresis group. The two groups were similar in terms of other baseline clinical and demographic characteristics. Seventeen patients (58.6%) in the insulin group and nine patients (47.4%) in the apheresis group exhibited Balthazar grades D-E. There was a rapid reduction (78.5%) in triglyceride level after the first session of apheresis. Insulin infusion resulted in a 44.4% reduction in mean triglyceride level in the first 24 h. The durations of fasting and hospital stay, and the rates of respiratory failure and hypotension, were similar between groups. More patients in the apheresis group experienced acute renal failure or altered mental status. Prognosis did not significantly differ between groups. Conclusion Although apheresis treatments are safe and effective, they provided no clear benefit over insulin infusion for HTG-associated pancreatitis.Item The relationship between fibrosis and nodule structure and esophageal varices(2019) Cosar, Arif Mansur; Yakar, Tolga; Serin, Ender; Ozer, Birol; Kayaselcuk, Fazilet; 31290750Background/Aims: The aim of the present study was to evaluate the histopathological findings of cirrhosis together with clinical and laboratory parameters, and to investigate their relationship with esophageal varices that are portal hypertension findings. Materials and Methods: A total of 67 (42 male and 25 female) patients who were diagnosed with cirrhosis were included in the study. The mean age of the patients was 51.6 +/- 19.0 (1-81) years. The biopsy specimens of the patients were graded in terms of fibrosis, nodularity, loss of portal area, central venous loss, inflammation, and steatosis. The spleen sizes were graded ultrasonographically, and the esophageal varices were graded endoscopically. Results: In the multivariate regression analysis, there was a correlation between the advanced disease stage (Child-Pugh score odds ratio (OR): 1.47, 95% confidence interval (CI): 1.018-2.121, p=0.040), presence of micronodularity (OR: 0.318, 95% CI: 0.120-0.842, p=0.021), grade of central venous loss (OR: 5.231, 95% CI: 1.132-24.176, p=0.034), and presence of esophageal varicose veins. Conclusion: Although thrombocytopenia and splenomegaly may predict the presence of large esophageal varices, cirrhosis histopathology is the main factor in the presence of varices.Item Population-based assessment of gastrointestinal symptoms and diseases: Cappadocia Cohort, Turkey(2019) Sezgin, Orhan; Akpinar, Hale; Ozer, Birol; Toruner, Murat; Bal, Kadir; Bor, Serhat; 31854305Background/Aims: The aim of this study was to determine the prevalence of symptoms and diseases of the lower and upper gastrointestinal system (GIS) in a population-based sample. Materials and Methods: The cross-sectional cohort study was conducted in Cappadocia cohort comprising the Gulsehir and Avanos districts. The "Gastrointestinal Symptom Questionnaire" was applied to persons over the age of 18 years. Results: The GI Symptom Questionnaire was applied to 3369 subjects, and height and body weight were measured in 2797 consenting subjects. Of the participants, 61% were female and the mean patient age was 50 +/- 15 years. At least one GI symptom was present in 70.6% of the cohort. The most common upper GI symptoms were gastric bloating (31.0%) and heartburn (29.1%). The most common lower GI symptom was abnormal defecation (33.5). The prevalence of upper GIS and lower GIS diseases was 32.7% and 12.9%, respectively, and the prevalence of togetherness of upper and lower GIS diseases was 9.9%. Prevalence of GIS disease was approximately 3 times higher in females (p<0.001). All of the upper and lower GI symptoms and the prevalence of upper GIS disease increased in line with Body mass index (BMI). Conclusion: This first population-based, cross-sectional cohort study revealed that the prevalence of GIS diseases is critically high for optimal public health. Special attention must be paid to these diseases while planning health policies and reimbursements.Item Viral hepatitis screening guideline before biological drug use in rheumatic patients(2016) Karadag, Omer; Kasifoglu, Timucin; Ozer, Birol; Kaymakoglu, Sabahattin; Kus, Yesim; Inanc, Murat; Keser, Gokhan; Kiraz, Sedat; 27708965Biological drugs (tumor necrosis factor inhibitors, rituximab, tocilizumab, abatacept, and tofacitinib) are important treatment alternatives in rheumatology, particularly for resistant patients. However, they may cause hepatitis B virus (HBV) and hepatitis C virus (HCV) reactivation; for instance, HBV reactivation may occur in a patient who is an inactive hepatitis B surface antigen (HBsAg) carrier or who has resolved HBV infection. Therefore, the screening of patients before biological treatment and the application of a prophylactic treatment, particularly with respect to latent HBV infections, are recommended when necessary. This guideline covers pre-treatment screening and follow-up recommendations, if required, with respect to viral hepatitides in rheumatology patients who are planned to be given biological drugs. Although this guideline is prepared for biological disease-modifying antirheumatic drugs (DMARDs), it is recommended to be used also for target-oriented DMARDS and medium-high dose corticosteroids (>7.5 mg prednisolone/day equivalent). It should be considered that the reactivation risk is higher when more than one immunosuppressive drug is used.Item The importance of salivary cortisol in the diagnosis of adrenal insufficiency in cirrhosis(2016) Araz, Filiz; Soydas, Baris; Ozer, Birol; Serin, Ender; 27210784Background/Aims: Reports on adrenal insufficiency (AI) are unexpectedly high in cirrhosis, and the diagnosis of this condition remains a challenge. We aimed to define the prevalence rate of AI in stable cirrhotic patients and determine the correlations of free cortisol and salivary cortisol with total cortisol. Materials and Methods: Between January 2011 and September 2011, 110 consecutive cirrhotic patients without any infection or hemodynamic instability were enrolled. Baseline total and salivary cortisol levels were measured. The free cortisol level was calculated according to the Coolens' formula. Post-stimulation total and salivary cortisol levels were measured, and the free cortisol level was recalculated. Results: The mean age of the patients was 62.1 +/- 11.4 years. There were 54 males (49.1%). The mean Child-Turcotte-Pugh (CTP) score was 7.2 +/- 2.3. Twenty-two (20%) patients were at the CTP-C level. AI was present in 23 (20.9%) and 17 (15.5%) of all patients according to the total and free cortisol criteria, respectively. For basal and stimulated levels, salivary cortisol rather than total cortisol correlates well with free cortisol. Conclusion: The diagnosis of AI on the basis of total cortisol measurement overestimates the prevalence of AI in cirrhosis. Salivary cortisol, which correlates well with free cortisol, is a promising alternative for the diagnosis of AI in cirrhotic patients.
