RESUMEN
OBJECTIVE: Ulcerative colitis is a chronic idiopathic disease that causes inflammation of the colon and rectum, progressing with relapses and remissions. Systemic inflammatory index (SII) and pan-immune inflammatory value (PIV) are newly developed biomarkers. There are many studies in the literature showing the relationship between SII and PIV with malignancies and inflammatory diseases. In this study we aimed to determine the relationship between SII and PIV with the activity of ulcerative colitis. MATERIALS AND METHODS: 146 Ulcerative colitis patients were retrospectively investigated by the time of diagnosis based on clinical, endoscopic and histolopathological findings. Patients and healthy individuals SII and PIV levels were calculated and compared with each other; and Mayo, DUBLIN, UCIES endoscopic subscores of patients were also obtained. Roc curve analysis were used to determine the cut-off value for PIV. RESULTS: SII (468.6 ± 203.5 vs. 823.1 ± 555.1; p < .001), PIV (288.2 ± 159.9 vs. 912.2 ± 924.1; p < .001), were statistically different between groups. PIV (OR: 1.157; (1.041-1.432), p = .036), was also observed to be the independent predictor of ulcerative colitis. The best cut off value of PIV in the prediction of ulcerative colitis was ≥ 506 with 89.6% sensitivity and 63.7% specificity (AUC = 0.812; 95% CI 0.763-0.854, p < .001). CONCLUSION: Based on the results of our study, we found that SII and PIV levels were significantly increased in ulcerative colitis patients at the time of diagnosis and were associated with disease severity in the endoscopic scores RACHMILEWITZ, UCEIS and DUBLIN scores, but not for MES score.

BACKGROUND: There is no consensus on the optimal drainage technique in the management of biliary anastomotic strictures occurring after right-lobe living-donor liver transplantation (RL LDLT). AIMS: To investigate whether there is a superiority between unilateral and bilateral drainage groups in terms of efficacy and safety of biliary drainage in RL LDLT patients undergoing double-biliary reconstruction. STUDY DESIGN: Retrospective Cohort Methods: Between January 2009 and August 2019, 1693 patients underwent RL LDLT. Of these, 182 patients who developed biliary anastomotic strictures out of the 306 patients who had double-biliary reconstruction, were included in the study. One hundred fifty-five patients with technical success were divided into 2 groups as unilateral (n=116) and bilateral (n=39) drainage groups. The groups were compared in terms of variable parameters such as clinical success, additional procedure, post-ERCP complication, procedures after clinical failure, hospital stay, mortality, and survival. RESULTS: The clinical success was higher in the bilateral group (70% vs. 82%, P = .201). In the initial and the follow-up periods, a total of 44 (38%) patients in the unilateral group were switched to the bilateral drainage group due to the increased need for stenting. The placement of a stent successfully solved the problem only in 28% (32/117) of the patients in the unilateral group, while this rate was 44% (17/39) in the bilateral group. The median follow-up time of both groups was 42 months, and was equal. The number of stent-free follow-up patients in the unilateral drainage group was less than that in the bilateral drainage group (4 and 7, respectively). CONCLUSION: An active attempt should be made for bilateral drainage in patients with biliary anastomotic stricture following RL LDLT. However, for patients in whom bilateral drainage is not possible, unilateral drainage may be recommended, with the placement of a maximum number of stents following primary biliary balloon dilatation, depending on the degree of stricture.

BACKGROUND AND OBJECTIVES: Acute toxic hepatitis can result in a different clinical course from a completely curable disease to subacute hepatitis, chronic hepatitis, and fulminant hepatitis failure, which is quite mortal. For this purpose, therapeutic plasma exchange (TPE) can be used for improving treatment outcomes by reducing the harmful substances caused with and/or without liver function in acute toxic hepatitis. We aimed to evaluate treatment outcomes in severe acute toxic hepatitis patients who applied early TPE procedure. MATERIALS AND METHODS: A total of 335 patients who received TPE between 2010-2021 were retrospectively screened and 59 (male/female, 30/29; min/max-age, 22-84) patients with acute toxic hepatitis who underwent TPE in the first 24 h were included in the study. TPE was performed in patients who had high total bilirubin level (>10 mg/dL). Laboratory parameters of the patients before and after the TPE procedure, number of patients developed complications of acute toxic hepatitis and mortality rates were evaluated for effectiveness of TPE. RESULTS: Acute toxic hepatitis was associated with hepatotoxic drugs in 44 (74.5 %), herbal medication 6 (10.2 %), mushroom poisoning 6 (10.2 %) and with substance abuse 3 (5.1 %) in patients. When the patients were compared based on INR, liver function tests, ammonia, lactate and Model For End-Stage Liver Disease (MELD) score at baseline, 48 h after TPE (independently of TPE number) and before final state a statistically significant decrease was observed in all parameters (p < 0.05). Fifty three (90 %) of patients improved without complications, the remaining 6 (10 %) patients were diagnosed with fulminant hepatitis. All these remaining patients died before liver transplantation (LTx) could be performed. CONCLUSION: TPE is a safe, tolerable therapy option and early TPE may improve treatment outcomes in severe acute toxic hepatitis.

BACKGROUND/AIMS: Although living donor liver transplantation (LDLT) has been accepted as a primary treatment for adults with end-stage liver disease, concerns about donor health have been emerged. As LDLT is technically complex, it creates perioperative morbidity and mortality risk in donors. Biliary complications such as stricture and leakage are seen most frequently in donors after liver transplantation. While some of these complications get treated with conservative approach, endoscopic, surgical, and percutaneous interventions may be required in some others. We aimed to present endoscopic retrograde cholangiography (ERC) results in donors who developed biliary complications after LDLT. MATERIALS AND METHODS: Between June 2010 and January 2018, a total of 1521 donors (1291 right lobe grafts, 230 left lobe grafts) of patients who underwent LDLT, were retrospectively reviewed. 63 donors who underwent ERC due to biliary complication, were included in the study. RESULTS: Biliary stricture was found in 1.6% (25/1521), biliary leakage in 2.1% (33/1521), and stricture and leakage together in 0.3% (5/1521) donors. Our endoscopic success rates in patients with biliary leakage, biliary stricture, and stricture and leakage were 85% (28/33), 92% (23/25), and 80% (4/5), respectively. Surgical treatment was performed on 12.6% (8/63) donors who failed ERC. CONCLUSION: We found that ERC is a successful treatment for post-LDLT donors who have biliary complications.

This study was designed to identify and assess risk factors for portal vein thrombosis (PVT) in patients with cirrhosis. A total of 98 cirrhosis patients with PVT were identified and 101 cirrhosis patients without PVT were chosen as the control group in this retrospective study. Several variables were measured and the two groups PVT and non-PVT were compared statistically. PVT was identified in 98 patients (10%). Significant differences in hematocrit, international normalized ratio, albumin, bilirubin and glucose were determined between the groups (P<0.05). Out of the thrombophilic risk factors in the patients with PVT factor V Leiden was identified in 8.8%, prothrombin gene 6.6% and methylenetetrahydrofolate reductase 2.2%. There was no difference in survival time between groups (P>0.05).
RESUMEN
Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is an autosomal recessive disorder characterized by gastrointestinal dysmotility, cachexia, ptosis, peripheral neuropathy and leukoencephalopathy. The diagnosis is often not made until 5-10 years after the onset of symptoms. MNGIE is caused by mutations in thymidine phosphorylase gene TYMP. Here, we present a 19-year-old boy with MNGIE who had a chronic intestinal pseudo-obstruction, and we describe his family history. Genetic analysis revealed a novel homozygous c.765+1G>C intronic mutation which is expected to disrupt splicing of TYMP in the patient. Family screening revealed that the brother was also affected and the mother was a carrier. MNGIE should be considered and genetic testing instigated if individuals with cachexia have neuromuscular complaints or symptoms of chronic intestinal pseudo-obstruction.

BACKGROUND: Helicobacter pylori eradication therapy improves the healing of various gastro-duodenal diseases such as chronic gastritis and peptic ulcer, and also reduces gastric cancer incidence. Several studies have reported on risk factors other than antibiotic resistance related to Helicobacter pylori eradication failure. OBJECTIVES: In this study, we aimed to investigate whether or not the serum levels of 25-hydroxy-vitamin D (25(OH)D) influence eradication rates of H.pylori. MATERIAL AND METHODS: 220 patients diagnosed with H.pylori gastritis using endoscopic biopsy had their 25-OH vitamin D levels measured via the electrochemiluminescence method before beginning eradication therapy of H.pylori. Gastric biopsies obtained at endoscopy were examined for H.pylori strains and histopathologic findings. All patients were treated with bismuth-containing quadruple therapy for 14 days. H.pylori eradication was determined via the 14C-urea breath test performed 4 weeks after the end of therapy. Based on the 25-OH vitamin D levels, the patients were divided into 2 groups: group 1 (deficient) had a vitamin D level of <10 ng/mL, while group 2 (sufficient) had a vitamin D level of ≥10 ng/ mL. RESULTS: Eradication was successful in 170 (77.2%) patients and failed in 50 (22.7%) patients. The prevalence of 25(OH)D deficiency was 30.5%. Mean 25(OH)D levels were significantly lower in the eradication failure group compared to the successful treatment group (9.13 ±4.7 vs 19.03 ±8.13; p = 0.001). There were significantly more patients with deficient 25(OH)D levels in the failed treatment group compared to the successful treatment group (p = 0.001). CONCLUSIONS: Our findings suggest that 25-OH vitamin D deficiency may be considered a risk factor related to eradication failure of H.pylori, which may lead to a need for supplementation of vitamin D before eradication of H.pylori.

Background. There are no studies investigating the relationship between endothelial nitric oxide synthase (eNOS) gene polymorphisms and hepatorenal syndrome (HRS). Aim. The purpose of this study is to elucidate whether eNOS gene polymorphisms (G894T and T-786C) play a role in the development of type-2 HRS. Methods. This study was carried out in a group of 92 patients with cirrhosis (44 patients with type-2 HRS and 48 without HRS) and 50 healthy controls. Polymorphisms were determined by polymerase chain reaction (PCR) and melting curve analysis. Results. We did not find any significant difference in allele and genotype distributions of the eNOS -T-786C polymorphism among the groups (p = 0.440). However, the frequency of GT (40.9%) and TT (13.6%) genotypes and mutant allele T (34.1%) for the eNOS G894T polymorphism were significantly higher (p < 0.001 and p < 0.001, resp.) in the HRS group than in both the stable cirrhosis (14.6%, 4.2%, and 11.5%, resp.) and the control (22.0%, 2.0%, and 13.0%, resp.) groups. Conclusion. The occurrence of mutant genotypes (GT/TT) and mutant allele T in eNOS -G894T polymorphisms should be considered as a potential risk factor in cirrhotic patients with HRS.
RESUMEN
There is controversial data regarding the relationship between uric acid (UA) and coronary artery disease and cardiovascular events. Despite the deleterious effects of hyperuricemia on endothelial function, the effect of UA on myocardial ischemia has not been previously studied. We aimed to investigate the relationship between UA and myocardial ischemia that was identified using dobutamine stress echocardiography (DSE). In this retrospective study, the laboratory and DSE reports of 548 patients were reviewed. The patients were divided into two groups based on the presence of ischemia and further subdivided into three groups according to the extent of ischemia (none, ischemia in 1-3 segments, ischemia in >3 segments). Serum UA levels were compared. Determinants of ischemia were assessed using a regression model. UA was increased in patients with ischemia and was correlated with the number of ischemic segments (p < 0.001). A cutoff value of UA > 5 mg/dl had 63.9 % sensitivity, 62.0 % specificity, 42.5 % positive predictive value (PPV), and 79.6 % negative predictive value for ischemia. When the positive DSE exams were further sorted according to the UA cutoff, the PPV of DSE increased from 80.2 to 94.0 %. Uric acid (odds ratio 1.51; 95 % CI 1.14-1.99), diabetes mellitus, HDL and glomerular filtration rate were found to be independent determinants of myocardial ischemia in DSE. Increased UA is associated with both the presence and extent of DSE-identified myocardial ischemia. A UA cutoff may be a good method to improve the PPV of DSE.

BACKGROUND/AIM: To determine whether macrophage migration inhibitory factor (MIF) and monocyte chemoattractant protein-1 (MCP-1) levels in patients with hepatitis B (HB) are different than in normal individuals and whether the HB surface antigen (HBs Ag) level and viral load are correlated with each other and with the two aforementioned parameters. MATERIALS AND METHODS: Sera were obtained from 52 chronic active HB (CAHB) patients and 33 healthy controls, and their MIF and MCP-1 levels were measured. Statistical analyses were performed. A value of P < 0.05 was considered statistically significant. RESULTS: The MIF and MCP-1 values of the control group were increased compared to those of the CAHB group. The MIF and MCP-1 levels were negatively correlated with HBs Ag levels and viral loads. The MIF and MCP-1 levels were positively correlated. The HBs Ag levels and the log10 of the viral loads were positively correlated. CONCLUSION: We conclude that the negative correlation of MIF and MCP-1 with viral load and HBs Ag levels may be due to T-cell deficiency, antinuclear antibody seropositivity, and/or inhibition of chemokine ligand 2 receptors by viral antigens. More studies with a greater number of subjects are needed to evaluate the potential role of MIF and MCP in CAHB.

OBJECTIVE: Gastric cancer is a worldwide aggressive tumor with a bad prognosis. The purpose of this study was to retrospectively investigate operative findings of 53 patients aged over 70 with gastric cancer who underwent laporoscopic operations in our clinic. MATERIAL AND METHODS: A retrospective review of all patients who underwent laporoscopic surgery for pathologically confirmed gastric cancer at our clinic between March 2008 and October 2010 was conducted. D1 resection (Level1 lymphadenectomy) was compared with D2 resection (Levels 1 and 2 lymphadenectomy). The two groups in which D1 and D2 Lymph node Dissection (LND) were applied were compared with respect to number of patients, sex, age, stage of disease, and score of American Society of Anesthesiologists (ASA). We analyzed surgical methods, the use of staplers, operative time, additional organ resections, hospital stay, postoperative complications and the need for re-operation, operative mortality, and the effects of prognostic factors on survival. RESULTS: The patient group consisted of 31 (58%) males and 22 (42%) females. Of the patients, 28 (52%) underwent D1 and 25 (48%) D2 LND. There was a significant difference between the two groups with regard to length of surgery (p < 0.01). The length of operation, blood loss, and transfusion requirement in the D2 group were significantly more than those in the D1 group. There was no mortality in cases that underwent additional organ resection. The survival times of cases with a ≤ 0.25 ratio of dissected number of lymph nodes to metastatic lymph nodes were significantly longer than those of other cases. The survival time of cases with perineural and vascular invasion was significantly shorter. The survival rates of Stage I patients was significantly higher than those of Stage III (p:0.002) and Stage IV (p:0.003) patients. CONCLUSIONS: Although extensive dissection had an increased morbidity, there was no significant statistical difference between the two procedures. Early complications should not be attributed only to the extent of LND. The important prognostic factors related to long-time survival are the stage of the tumor, perineural and perivascular invasion, and metastatic lymph nodes.
RESUMEN
PURPOSE: To evaluate the accuracy of cardiac computed tomography (CT) parameters and pulmonary artery (PA) obstruction (OS) scores in determining the echocardiographic right ventricular dysfunction (RVD) in hemodynamically stable patients with acute pulmonary embolism (PE). MATERIALS AND METHODS: A total of 120 patients with acute PE were included in the study. Right ventricle/left ventricle ratio (RV/LV); PA axial diameter; superior vena cava (SVC) axial diameter; and Ghanima, Miller, Qanadli, and Mastora obstruction scores were obtained using CT. RVD was assessed by echocardiography. The patients were divided into two groups based on the presence or absence of RVD. RESULTS: RV/LV ratio, SVC axial diameter, PA axial diameter, and Miller, Qanadli, and Mastora scores were significantly increased in the RVD group. Multivariate logistic regression analysis showed that RV/LV ratio [OR 6.36 (2.02-279.46 95 % CI), p = 0.01] and PA axial diameter [OR 5.02 (1.02-1.26 95 % CI), p = 0.03] were independent predictors of echocardiographic RVD. Predictive values of these parameters were improved when combined with other intragroup cutoff values. A cutoff value for the RV/LV ratio of >1.08 had 81.43 % sensitivity, 52.08 % specificity, 71.3 PPV, and 65.8 NPV for prediction of RVD. CONCLUSION: Tomographic axial diameters enable more accurate predictions of RVD than OS scores do.

BACKGROUND: Acute pulmonary embolism (PE) is a serious clinical condition characterised by a high mortality rate. Previous studies showed that leukocytosis was associated with recurrences of venous thromboemboli, major bleeding and increased mortality. The aim of the present study was to investigate the prognostic value of neutrophil to lymphocyte ratio (NLR) in patients with acute PE during short term follow-up. METHOD: A total of 640 patients were screened by I26 code of ICD-9 and 359 patients were included as cases of confirmed acute PE. Admission blood counts and clinical data were obtained from medical charts. The predictors of 30-day mortality were examined. RESULTS: Fifty-one out of 359 patients (14.2%) included in the study died during 30 days follow-up. In multivariate Cox regression analysis systolic blood pressure (HR:0.97 (0.94-0.99 CI95%), p=0.019), diabetes mellitus (HR:3.3 (1.30-8.39 CI95%), p=0.012), CK-MB(HR:1.03 (1.01-1.06 CI95%), p=0.024) and NLR (HR:1.03 (1.01-1.06 CI95%), p=0.008) were predictors of 30-day mortality. An optimal cut-off value of NLR was determined as 9.2 by using ROC curve. Hazards ratio of NLR>9.2 was found to be 3.60 (1.44-9.18 CI95%, p=0.006). NLR>9.2 had a sensitivity, specificity, negative predictive value, and positive predictive value of 68.6%, 80.5%, 93.9% and 36.5%, respectively. CONCLUSION: NLR on hospital admission may be a predictor of 30-day mortality in acute PE. Since complete blood count is a part of the routine laboratory investigation in the most hospitalised patients use and preliminary promising results of this study, NLR should be investigated in future prospective randomised trials regarding prognostic value in acute PE.

OBJECTIVES: Although elevated red blood cell distribution width (RDW) is associated with adverse outcomes in patients with cardiovascular disease, its role in demonstrating the presence and extent of myocardial ischemia for coronary artery disease is not known. The purpose of this study is to investigate the relationship between RDW and myocardial ischemia by using dobutamine stress echocardiography (DSE). METHODS: A total of 917 patients were included in this prospective study. A complete blood analysis was performed for RDW before DSE. According to DSE results, patients were divided into two groups: DSE negative and DSE positive. According to the number of ischemic segments in DSE, patients were divided into three groups: no-ischemic segment, 1-3 ischemic segments, and ≥4 ischemic segments. In addition, coronary angiography results of DSE-positive groups were assessed in respect of RDW. RESULTS: The RDW of the DSE-positive group (n=277) was higher than for the DSE-negative group (n=640) (13.5±1.5 vs. 12.7±1.3%, P<0.001, respectively). Elevated RDW values were also related to higher number of ischemic segments (no-ischemic segment group: 12.7±1.3, 1-3 ischemic segments group: 13.2±1.5, and ≥4 ischemic segments group: 14.2±1.3, P<0.001). A receiver operating curve analysis showed a cut-off value of RDW greater than 13.5% for predicting myocardial ischemia (sensitivity: 57.0%, specificity: 77.8%, positive predictive value: 52.7%, negative predictive value: 80.7%). In addition, positive predictive value of DSE was increased from 82.4 to 94.2% for detecting coronary artery disease by coronary angiography, when RDW (>13.5%) was used. CONCLUSION: RDW is related to the presence and extent of myocardial ischemia in DSE. A high RDW increases the diagnostic accuracy of DSE.

BACKGROUND: Epicardial fat thickness (EFT), an indicator of visceral obesity, and leptin are 2 novel markers for studying the obstructive sleep apnea (OSA) population. This study aimed to investigate the effects of gender on leptin levels and EFT, and the relation with OSA severity. METHODS: A total of 149 patients with OSA (female/male 55/94 and mean age 50.8 ± 9.2 years) and 50 control patients (female/male 24/26 and mean age 48.9 ± 8.8 years) were included in the study. The study population was divided into 4 groups according to apnea/hypopnea index (AHI) as control (AHI <5), the mild OSA (AHI 5-14), the moderate OSA (AHI 15-29), and the severe OSA (AHI ≥30). EFT was obtained from parasternal long-axis and parasternal short-axis echocardiographic images. RESULTS: Leptin levels among females were significantly higher than among males (10.5 [7.8] vs. 5.4 [4.5] ng/mL, P = 0.001, respectively). Among women, leptin levels were significantly higher in the severe OSA group compared to the control group (9.8 [9.0] vs. 15.5 [10.1] ng/mL, P = 0.05, respectively). Conversely, no relation was observed between OSA severity and the leptin levels among men. EFT was not significantly different between the 2 genders (P > 0.05). EFT was thicker in the severe OSA group than in the control and mild OSA groups among women, whereas EFT was not changed according to OSA severity among males (P > 0.05). CONCLUSION: Leptin and EFT may be a valuable parameter in the evaluation of OSA severity in women than in men.

BACKGROUND: Atrial fibrillation (AF) is the most common sustained cardiac rhythm disturbance encountered in clinical practice and is associated with impaired quality of life. Data from the previous studies have shown that sleep quality (SQ), as a component of life quality, may also deteriorate in patients with AF. However, it remains unclear; we do not know whether SQ improves after sinus rhythm is maintained. Therefore, we aimed to examine the relationship between SQ and AF, as well as the effects of sinus rhythm restoration with direct current cardioversion (DCC) on SQ among patients with persistent AF. METHODS: One hundred fifty-three patients with a diagnosis of nonvalvular AF and 150 age-matched control subjects with sinus rhythm were recruited. SQ was assessed using the Pittsburgh Sleep Quality Index (PSQI). The study was designed with two stages. First, the difference in SQ between AF patients and age-matched controls was examined. Patients with global PSQI scores greater than 5 were defined as "poor sleepers." Thus, a higher global PSQI score indicated worsened SQ. Predictors of poor SQ were also analyzed using a regression model. Second, the effect of rhythm control on SQ was studied in patients with AF who were eligible for DCC. Of the 65 patients with persistent AF, 54 patients with successful cardioversion were followed for 6 months. The remaining 11 patients, whose cardioversion was unsuccessful, were not followed. After 6 months of follow-up, the PSQI scores of patients with sinus rhythm maintenance (n = 39) and patients with AF recurrence (n = 15) were reassessed. Changes in global PSQI scores (baseline vs after 6 months) were analyzed. RESULTS: The PSQI scores were significantly higher in the AF group compared to the control group (9.4 ± 4.6 vs 5.8 ± 4.1, P = 0.001, respectively). The prevalence of poor sleepers was significantly higher in the AF group (76%) than in the control group (45%) (P < 0.001 by the χ(2) test). Multivariate logistic regression analysis showed that AF (odds ratio [OR]: 3.36, 95% confidence interval [CI]: 2.00-5.55), age (OR: 1.02, 95% CI: 1.00-1.04), and diabetes mellitus (OR:1.79, 95% CI: 1.03-3.14) were independent predictors of poor SQ. In the second stage, the effect of rhythm control on the SQ of the 54 patients with successful DCC was analyzed. PSQI scores improved significantly between baseline and the 6 months in sinus rhythm maintenance group (8.7 ± 4.1 vs 7.2 ± 3.8, P < 0.001, respectively). However, in the AF recurrence group, the change in global PSQI scores between baseline and the sixth month was not statistically significant (9.8 ± 4.5 vs 9.2 ± 4.2, P = 0.56, respectively). CONCLUSION: Patients with AF have shorter sleep duration and poor SQ. Maintenance of sinus rhythm after DCC may have a favorable effect on the SQ of patients with AF. Nevertheless, AF is an independent predictor of poor SQ.

Electrolyte disorders can alter cardiac ionic currents and depending on the changes can promote proarrhythmic effects. Potassium (K(+)) is the most common intracellular cation related to arrhythmic disorders. Hyperkalemia is mainly seen in the setting of impaired renal function. Severe hyperkalemia may lead to rhythm disorders. Herein, we report a patient with accelerated idioventricular rhythm (AIVR) due to hyperkalemia, which was successfully treated with glucose-insulin (GI) infusion.
