    The relationship between fibrosis and nodule structure and esophageal varices
    (2019) Cosar, Arif Mansur; Yakar, Tolga; Serin, Ender; Ozer, Birol; Kayaselcuk, Fazilet; 31290750
    Background/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.

    The importance of salivary cortisol in the diagnosis of adrenal insufficiency in cirrhosis
    (2016) Araz, Filiz; Soydas, Baris; Ozer, Birol; Serin, Ender; 27210784
    Background/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.
