Comparison of Fibroscan, Shear Wave Elastography, and Shear Wave Dispersion Measurements in Evaluating Fibrosis and Necroinflammation in Patients Who Underwent Liver Biopsy.

OBJECTIVE: Our aim was to predict these stages of hepatic fibrosis and necroinflammation using measurements from two-dimensional shear wave elastography (2D-SWE), transient elastography (Fibroscan, TE), and shear wave dispersion (SWD). MATERIALS AND METHODS: In this prospectively designed study, chronic liver patients with nonspecific etiology whose biopsy was performed for up to 1 week were included. Two-dimensional SWE, SWD, and TE measurements were performed. The METAVIR and F-ISHAK classification was used for histopathological evaluation. RESULTS: Two-dimensional SWE and TE were considered significant for detecting hepatic fibrosis. In distinguishing ≥F2, for 2D-SWE, area under the receiver operating characteristics (AUROC) was 0.86 (confidence interval [CI], 0.75-0.96) for the cutoff value of 8.05 kPa ( P = 0.003); for TE, AUROC was 0.79 (CI, 0.65-0.94) for the cutoff value of 10.4 kPa ( P < 0.001). No significance was found for TE in distinguishing ≥F3 ( P = 0.132). However, for 2D-SWE, a cutoff value of 10.45 kPa ( P < 0.001), with AUROC = 0.87 (CI, 0.78-0.97) was determined for ≥F3. Shear wave dispersion was able to determine the presence of necroinflammation ( P = 0.016) and a cutoff value of 15.25 (meter/second)/kiloHertz ([m/s]/kHz) ( P = 0.006) and AUROC of 0.71 (CI, 0.57-0.85) were calculated for distinguishing ≥A2. In addition, a cutoff value of 17.25 (m/s)/kHz ( P = 0.023) and AUROC = 0.72 (CI, 0.51-0.93) were found to detect severe necroinflammation. The cutoff value for SWD was 15.25 (m/s)/kHz ( P = 0.013) for detecting ≥A2 in the reversible stage of fibrosis (F0, F1, and F2), and AUROC = 0.72 (CI, 0.56-0.88). CONCLUSIONS: Two-dimensional SWE and TE measurements were significant in detecting the irreversible stage and the stage that should be treated in hepatic fibrosis noninvasively. Shear wave dispersion measurements were significant in detecting necroinflammation noninvasively.

Investigation of the Relationship Between Laparoscopic Sleeve Gastrectomy and Gastroesophageal Reflux Disease Using 24-hour Multichannel Intraluminal Impedance With pH Testing According to Current Consensus.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a popular weight loss procedure with potential effects on gastroesophageal reflux disease (GERD). However, research on the association between LSG and GERD using objective evaluation criteria, such as multichannel intraluminal impedance combined with pH testing (MII-pH), is limited. This study aimed to investigate the impact of LSG on GERD using MII-pH and current consensus guidelines. MATERIALS AND METHODS: It was conducted as a prospective clinical study on 33 patients who underwent LSG between January 2022 and August 2022. MII-pH and high-resolution manometry were performed preoperatively and 3 to 6 months postoperatively. GERD diagnosis was based on MII-pH results using the Lyon and Update Porto consensus guidelines. RESULTS: Postoperative MII-pH analysis revealed a significant increase in acid reflux time, acid exposure time, reflux index, esophageal clearance, total reflux time, and longest reflux period. Weak acid reflux episodes decreased, while Demeester score and alkaline reflux showed nonsignificant increases. Pathologic reflux significantly increased postoperatively based on MII-pH diagnosis. High-resolution manometry showed a significant increase in unsuccessful motility. CONCLUSION: Although the Demeester score calculation consists of 6 metrics, including acid exposure time, the acid exposure time is more specific in detecting pathologic reflux. Pathologic GERD increases significantly with LSG in the early period. Therefore, preoperative and postoperative endoscopy and MII-pH can provide valuable information regarding the need for closer follow-up after LSG.

Concomitant Crohn's Disease and Anti-Glutamic Acid Decarboxylase (GAD)-Associated Autoimmune Encephalitis: A Case Report.

Crohn's disease is an inflammatory, autoimmune disorder that predominantly affects the intestines but can also affect extraintestinal organs. Certain neurological conditions, such as autoimmune encephalitis, can develop along with this disease. In this case report, we present a case of anti-glutamic acid decarboxylase (GAD) antibody-associated autoimmune encephalitis that occurred shortly after the diagnosis of Crohn's disease and was unrelated to the treatment and nutritional deficiencies. After a significant weight loss (24 kg) and persistent diarrhea, the patient was diagnosed with Crohn's disease by colonoscopy and biopsy. Within two weeks after the diagnosis, he experienced altered consciousness and memory impairment, followed by a rapid deterioration in consciousness and respiratory distress, leading to intubation and admission to the intensive care unit. His brain MRI revealed asymmetrical diffuse cortical diffusion restrictions, hyperintense signals on fluid-attenuated inversion recovery (FLAIR) sequences, and diffuse pachymeningeal contrast enhancement involving both cingulate gyri, bilateral insular cortices, amygdalae, hippocampi, and the right precuneus. Analysis of cerebrospinal fluid (CSF) revealed a slight elevation of CSF proteins, and the patient tested positive for serum anti-GAD antibodies. The patient responded favorably to a seven-day course of intravenous methylprednisolone, five days of intravenous immunoglobulin (IVIG), and oral corticosteroids. Subsequent treatment consisted of monthly IVIG, azathioprine, and vedolizumab, resulting in no neurologic sequelae except mild amnesia. A follow-up MRI at three months showed a nearly complete disappearance of the lesions. This is the first reported case of anti-GAD-associated encephalitis occurring in the presence of Crohn's disease.

Is the Y90-radioembolization treatment effective on the intermediate-advanced stage of hepatocellular carcinoma and what is the albumin-bilirubin score's prediction factor for survival?

Background and Aim: Radioembolization (RE) is a one of the palliative treatments that have been used to down stage and/or increase the survival time in intermediate-advanced stages of HCC. We aimed to evaluate the clinical impact of RE and the clinical use of the albumin-bilirubin (ALBI) score as a predictor for survival in HCC patients. Materials and Methods: Fifty-nine unresectable hepatocellular carcinoma (HCC) patients were enrolled. RE was performed in 28 of them (group 1) and 31 patients were followed up in the natural course (NC) (group 2). Patients were classified according to the Child-Pugh score (only cirrhotic patients), Barcelona clinic liver cancer (BCLC) staging, and ALBI scores were also calculated. Results: All patients in Group 1 were cirrhotic and their BCLC stages were as follows: 60.7% stage B and 39.3% stage C. In Group 2, 83.9% of patients were cirrhotic and their BCLC stages were as follows: 9.7% stage B, 51.6% stage C, and 38.7% stage D. Mortality rates were 82% and 100% in Groups 1 and 2, respectively. The median overall survival (OS) was 13.5 months (95% CI: 10.4-16.6 months) and 4.5 months (95% CI: 3.5-5.5 months) in Groups 1 and 2, respectively (p=0.000). When RE was applied to patients with ALBI Grade 1 and 2, the median OS was statistically higher than in the NC group, respectively (p<0.001, p<0.001). Conclusion: RE is an effective treatment method at the advanced stages of HCC. The ALBI score is a more useful and practical than the other prognostic tools.

Small Bowel Video Capsule Endoscopy Guidance in Practice: Expert Opinion Report.

Capsule endoscopy, in clinical use since the 2000s, has disrupted the diagnosis of various small bowel diseases, especially obscuregastrointestinal bleeding. An overview of information on indications, contraindications, patient management, and patient preparationfor capsule endoscopy, which allows the evaluation of the entire gastrointestinal tract, will be helpful for both referrers and capsuleendoscopy. This review critically considers current evidence on the optimal clinical use of capsule endoscopy and addresses areas in the "gray zone."

The effects of IL28B rs12979860 and rs8099917 polymorphism on hepatitis B infection.

OBJECTIVE: The purpose of this study was to evaluate the relationship of IL28B rs12979860 and rs8099917 polymorphisms with the clinical, histological, and virological outcomes of patients with chronic hepatitis B (CHB) also the treatment responses of patients who received Nucleos(t)ide analogs (NAs) therapy. METHODS: This study included 152 CHB patients who were underwent liver parenchymal biopsy. The IL28B rs12979860 and rs8099917 polymorphism were genotyped using the TaqMan assay. RESULTS: The IL28B rs12979860 CC and IL28B rs8099917 TT were identified as the genotypes with the highest frequency in all patients. On the other hand, IL28B rs12979860 TT and IL28B rs8099917 GG were the genotypes with the lowest frequency. The frequency of IL28B rs8099917 TG genotype was significantly different between patients with hepatitis B, who has histologically defined liver cirrhosis and no-fibrosis (p=0.02). In addition, a statistically significant correlation was found between the presence of IL28B rs8099917 G allele and virological unresponsiveness to NAs treatments in CHB patients (p=0.028). CONCLUSION: The presence of the IL28B rs8099917 G allele in CHB patients might be associated with the risk of developing cirrhosis and virological unresponsiveness to NAs treatments.

Cell-free methylation of RASSF1 and CDKN2AIP genes in the diagnosis of hepatocellular carcinoma associated with hepatitis B virus cirrhosis.

Background and Aim: Chronic hepatitis B virus (HBV) infection is a major cause of hepatocellular carcinoma (HCC). Circulating cell-free DNA (cfDNA) methylation of tumor suppressor genes are emerging potential biomarkers in HCC. We aimed to evaluate the cfDNA methylation status of RASSF1 and CDKN2AIP genes in patients with liver cirrhosis (LC) with or without HCC caused by HBV. Materials and Methods: A total of 47 patients with HBV cirrhosis were included in the study. Patients were divided into two groups: HCC and LC (HCC+LC, n=22) and HBV cirrhosis only (LC, n=25). cfDNA was isolated from the plasma samples of the patients. Methylation analysis was performed for RASSF1 and CDKN2AIP genes. Results: Mean methylation percentage of CDKN2AIP gene was 0.001±0.004% in the HCC+LC group and 0.008±0.004 % in the LC only group. The mean methylation percentage of RASSF1 gene was 5.1±16.1% in the HCC+LC group and 9.7±25.9% in the LC only group. The methylation rate of CDKN2AIP was significantly lower in the HCC+LC group (p=0.027). A positive correlation was found with the absence of cfDNA methylation of CDKN2AIP gene in the presence of HCC (R=0.667, p=0.018). Conclusion: cfDNA methylation of CDKN2AIP and RASSF1 genes may provide important diagnostic information regarding the development of HCC in the setting of HBV cirrhosis.

Comparison of S gene mutations in patients with occult and chronic hepatitis B virus infection.

BACKGROUND AND AIM: This study aimed to detect mutations in the HBV S gene and evaluate their relationship to occult hepatitis B virus (HBV) infection (OBI). METHODS: The study included 32 patients with negative serum HBsAg and HBV DNA who underwent liver biopsy due to different clinical indications defined as the OBI group and 32 patients who underwent liver biopsy due to chronic hepatitis B (CHB) as the comparison group. The HBV S gene region was amplified by Nested PCR, and Sanger sequencing was performed. RESULTS: At least one amino acid (aa) mutation was detected in the major hydrophilic region (MHR) of the HBV S gene in 14/32 (43.75%) of the patients with OBI and 8/32 (25.0%) with CHB. The genotype of all patients with OBI and CHB was HBV/D. Although 9 (28.1%) of the cases with OBI had sub-genotype HBV/D3, none of the patients with CHB had sub-genotype HBV/D3. Unlike patients with CHB, L15*, D33N, Q51P, V63F, L91I, P108S, T115I, P120L, T125M, Q129H, T189I, L216F, P217L mutations were detected in the HBV S gene in OBI cases. Also, P127T aa polymorphism was frequently detected. Mutation frequency in the HBV S gene in the major hydrophilic region (MHR) was higher in patients with OBI with sub-genotypes HBV/D3 and D2 than those with HBV/D1 and those with serotype HBV/ayw3 compared to those with HBV/ayw2 (p < 0.05). CONCLUSIONS: Sub-genotypic-specific mutation patterns were seen in the "a" determinant region and T helper cell epitopes of HBsAg, especially in the C-terminus domain; this may be associated with OBI.

What is the clinical impact of occult HBV infections and anti-HBc positivity in patients with chronic hepatitis C?

Occult hepatitis B infection (OBI) is defined by the persistence of the hepatitis B virus (HBV) genome in the liver of individuals testing negative for hepatitis B surface antigen (HBsAg). Hepatitis B core antibody (anti-HBc) is the serological marker that indicates HBV exposure. The impact of anti-HBc and OBI on patients with chronic hepatitis C remains unclear. The aim of the present study was to determine the prevalence of anti-HBc and OBI and to evaluate their impact on the clinical and pathological outcomes of patients with chronic hepatitis C. The study included 59 HBsAg-negative chronic hepatitis C patients who underwent a liver parenchymal biopsy. The presence of HBV DNA was investigated using an in-house nested PCR method. OBI was detected in 16 (27.1%) of the 59 cases and also in 10 (62.5%) of 22 (37.3%) anti-HBc-positive patients. None of the patients had positive serum HBV DNA. OBI was associated with the presence of anti-HBV antibodies (P < 0.05). There was also an association between anti-HBc positivity and the activity grades and fibrosis stages of the liver and also a prevalence of liver steatosis (P < 0.05). Positive anti-HBc results may predict OBI and may also be associated with the progression of liver injury in HBsAg-negative patients with chronic hepatitis C. Therefore, it is suggested that patients with chronic hepatitis C should be screened for anti-HBc positivity, and anti-HBc-positive patients should be carefully evaluated for disease progression.

Is Having Inflammatory Bowel Disease a Risk Factor for Severe Acute Respiratory Syndrome Coronavirus 2?

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 virus was found to have effects not only in the lungs but also in many different organs. We aimed to evaluate the management of our patients with inflammatory bowel disease in this pandemic, the incidence of coronavirus disease 2019 in terms of clinical, medical treatment, and features of inflammatory bowel disease, and to investigate the effects of the severe acute respiratory syndrome coronavirus 2 on this particular group of patients. METHODS: During the coronavirus disease 2019 pandemic, 207 patients who had inflammatory bowel disease for at least 6 months were questioned for coronavirus disease 2019 at their outpatient clinic admissions, and their medical records were evaluated prospectively. RESULTS: Of the 207 patients, 146 had Crohn's disease. The mean disease duration was determined as 118.15 ± 72.85 months. Of the patients, 127 (61.4%) were using mesalazine, 110 (53.1%) azathioprine, and 148 (71.5%) biological agents. It was found that 66 (31.9%) patients changed their medications during the coronavirus disease 2019 pandemic. As a medication change, anti-Tumor Necrosis Factor (TNF) dose was observed to be omitted most frequently at a rate of 80%. Diarrhea was present in 20.8%, abdominal pain in 20.3%, nausea in 10.6%, anorexia in 13.5%, and weight loss in 15.9% of the patients. Twelve (5.79%) patients were diagnosed with coronavirus disease 2019. Lung involvement was present in 11 (91.7%) of the patients diagnosed with coronavirus disease 2019. Of the patients diagnosed and not diagnosed with coronavirus disease 2019, 75% vs. 71.6% were using biological agents (P = .80), respectively. Half of the patients diagnosed with coronavirus disease 2019 were active in terms of inflammatory bowel disease at the time of diagnosis, and 2 of these patients were severely active. CONCLUSION: The incidence of coronavirus disease 2019 infection in patients with inflammatory bowel disease was not different from the general population during the severe acute respiratory syndrome coronavirus 2 pandemic. Coronavirus disease 2019 infection does not progress with poor prognosis in patients with inflammatory bowel disease who receive immunosuppressive therapy including biological agents.

Is there any predictor for relapse after treatment withdrawal in autoimmune hepatitis patients in the real life?

BACKGROUNDS AND AIMS: In autoimmune hepatitis, there are uncertainties about whether to discontinue the treatment, when the treatment should be discontinued, and the risks of relapse in the cases where remission is achieved with immunosuppressive therapy. In this study, patients with AIH, whose immunosuppressive treatments were discontinued, were evaluated for the rates of remission and the risk of relapse. MATERIALS AND METHODS: A total of 119 patients, who were diagnosed with AIH based on the AIHG scoring systems between 1990 and 2015, were evaluated. Patients were receiving standard azathioprine and steroid therapy. The treatment was discontinued in patients, who had been receiving treatment for at least 2 years, who had no clinical complaints, and whose aminotransferases were normal and when an increase occurred in AST values more than two times the normal after the treatment was interrupted, the case was considered as a relapse. RESULTS: Among the patients, 83%(n = 99) were women. When the patients were diagnosed with AIH, their mean age was 36 ± 16(8-79) years; 70.6%(n = 84) were type 1, 3.4%(n = 4) type 2, and 26%(n = 31) were autoantibody-negative AIH. At the time of discontinuation, liver biopsy was performed in 8 of the patients and minimal-mild abnormalities were detected. Patients whose treatment was discontinued received treatment for an average of 101 ± 75(range: 24-280, median: 68.5) months; and, they were followed up for an average of 19 (1-110) months during the period without medication. Relapse occurred in 67%(n = 12) of the patients with drug withdrawal. Relapse occurred within the first 12 months in 67% of these patients (n = 8) and developed with an acute hepatitis attack in 42%. None of the clinical, laboratory, and histological data were found to be effective on relapse. CONCLUSION: In patients with AIH, relapse occurs in two-thirds of patients within an average of 19 month after the discontinuation of the medication. Most relapses occur at the early period and they are accompanied by an acute hepatitis attack.

Metastases to the Stomach: Clinicopathologic Features of Metastases Mimicking Gastric Primaries.

OBJECTIVE: Metastatic involvement of the stomach is a rare event. Our aim in this study was to document the clinicopathological findings in patients with gastric metastases and find out if there are any potentially significant features to be used in the differential diagnosis. MATERIAL AND METHOD: Our cohort consisted of 17 histologically verified gastric metastasis cases. Clinical, endoscopic and microscopic features were retrospectively analyzed. RESULTS: The primary sites were the breast, skin, lungs, ovaries, colon, and gluteal soft tissue. Three patients were symptomatic because of the metastatic involvement of the stomach and 9 patients had concomitant metastasis in other sites. Invasive lobular breast carcinoma and malignant melanoma were the most common metastatic malignancies. The most common macroscopic appearance was the diffuse infiltrative type (Borrmann Type 4). Most of the metastatic lesions endoscopically mimicked primary gastric cancer. Furthermore, some of the metastatic lesions, particularly invasive lobular carcinoma of the breast and malignant melanoma, displayed histopathologic features similar to the primary gastric malignancies to a certain extent. CONCLUSION: The possibility of metastatic involvement of stomach must be kept in mind while dealing with a gastric mass lesion in a cancer patient, even though the clinical and endoscopic features suggest primary gastric cancer. Our study points out the importance of conveying the information about medical history and clinical findings of the patients for correct pathologic differential diagnosis.

Indications, effectiveness and safety of percutaneous endoscopic gastrostomy: A single center experience and literature review.

BACKGROUND AND OBJECTIVES: Percutaneous endoscopic gastrostomy (PEG) has been widely used since 1980 in enteral feeding of patients that are not able to be fed orally for a long time. The aim of this study is to evaluate the PEG indications, effectiveness and PEG related complications from a single center in Istanbul, Turkey. METHODS AND STUDY DESIGN: 265 patients with PEG who were followed up by the clinical nutrition team of a university hospital between 2010-2018 were evaluated retrospectively. Nutritional Risk Screening-2002 (NRS-2002) test, anthropometric measurements, bioelectrical impedance analysis and laboratory data were used to evaluate the patients' nutritional status. RESULTS: The most common indications for PEG were dementia (35.1%), amyotrophic lateral sclerosis (22.6%), stroke (15.8%), and cancer (14%). The mean body weight of the patients was increased after PEG (63.5±12.2 vs 62.0±12.7 kg). Mid upper arm circumference and calf circumference of the patients increased after PEG (27.5±2.5 vs 25.4±3.1 cm and 32.2±7.9 vs 29.6±5.9 cm, respectively). Serum albumin of the patients was increased significantly after PEG (3.34±0.69 g/dL to 3.64±0.65 g/dL) without any significant change in serum CRP. Subgroup analyses showed a significant increase in the mean serum albumin of patients with dementia after PEG (3.23±0.67 g/dL to 3.54±0.58 g/dL). Local insertion site infection occurred in 15 patients (5.6%) and only 3 patients had systemic inflammatory symptoms after local infection (1.1%). CONCLUSIONS: The results of our study showed that long-term enteral feeding with PEG is an effective and safe method that provides improvement in nutritional status.

What is the effective clinical use of small bowel capsule endoscopy in real life?

Capsule endoscopy is a noninvasive and easy method for evaluating the gastrointestinal tract. Since the wireless capsule endoscopy system was first developed, many new technical improvements have been made in order to gain maximum benefit from the procedure. However, at this stage, it remains a diagnostic modality, the main indication for its use being obscure gastrointestinal bleeding. Capsule endoscopy is only contraindicated in symptomatic intestinal obstruction. New indications for use and therapeutic options may become possible with the further development of nanotechnologies.

The effect of liver test abnormalities on the prognosis of COVID-19.

INTRODUCTION: COVID-19 caused by the SARS-CoV-2 continues to spread rapidly across the world. In our study, we aim to investigate the relationship between the liver enzymes on admission (AST, ALT, ALP, GGT) and severity of COVID-19. We evaluated course of disease, hospital stay, liver damage and mortality. MATERIALS AND METHODS: Our study included 614 patients who were hospitalized with the diagnosis of COVID-19 between 03.16.20 and 05.12.20. Patients with liver disease, hematological and solid organ malignancy with liver metastases were excluded, resulting in 554 patients who met our inclusion criteria. We retrospectively evaluated liver transaminase levels, AST/ALT ratio, cholestatic enzyme levels and R ratio during hospital admission and these were compared in terms of morbidity, mortality and clinical course. RESULTS: Mean age of 554 subjects were 66.21±15.45 years, 328 (59.2%) were men. The mean values of liver enzymes on admission were AST (36.2±33.6U/L), ALT (34.01±49.34U/L), ALP (78.8±46.86U/L), GGT (46.25±60.05U/L). Mortality rate and need for intensive care unit were statistically significant in subjects that had high ALT-AST levels during their admission to the hospital (p=0.001). According to the ROC analysis AST/ALT ratio was a good marker of mortality risk (AUC=0.713: p=0.001) and expected probability of intensive care unit admission (AUC=0.636: p=0.001). R ratio, which was used to evaluate prognosis, showed a poor prognosis rate of 26.5% in the cholestatic injury group, 36.1% in the mixed pattern group and 30% in the hepato-cellular injury group (p 0.001). CONCLUSIONS: ALT-AST elevation and AST/ALT ratio >1 was associated with more severe course and increased mortality in COVID-19.

Inflammatory bowel disease and mycobacteria: how much can we trust isoniazid prophylaxis during antitumor necrosis factor therapy?

OBJECTIVES: Isoniazid (INH) prophylaxis is recommended for the prevention of tuberculosis (TB) reactivation before or/and during initiation of treatment with tumour necrosis factor antagonists (anti-TNF agents). Nonetheless, the long-term effectiveness of chemoprophylaxis is not clear. In this study, we aimed to evaluate the characteristics of patients who developed TB reactivation in spite of INH prophylaxis associated with anti-TNF treatment. PATIENTS AND METHODS: In this retrospective study, medical records of 1263 patients with inflammatory bowel disease were reviewed. Baseline TB screening tests (purified protein derivative test and/or QuantiFERON-TB Gold test) were performed on all patients before initiation of anti-TNF therapy. Patients with purified protein derivative of more than 5 mm and/or a positive result of the QuantiFERON-TB Gold test received INH prophylaxis for 9 months. We analysed the data of patients diagnosed with TB reactivation during the anti-TNF treatment despite INH chemoprophylaxis. RESULTS: Overall, 175 patients underwent anti-TNF treatment. Sixty of these 175 patients had pretreatment testing showing latent TB infection and therefore were treated concomitantly with INH for 9 months in addition to their anti-TNF treatment. TB reactivation occurred in four of these 60 co-INH/anti-TNF treated patients. Active TB was diagnosed after 37.5±27 (range: 18-84) months of anti-TNF treatment. In two of the four patients that active TB was diagnosed, was also detected other Mycobacterium spp.: M. bovis in one patient and M. genavense in the other one. CONCLUSION: INH chemoprophylaxis may not prevent the reactivation of TB during anti-TNF therapy in the long-term. Patients should be carefully and periodically screened for TB reactivation during anti-TNF therapy.

Changing epidemiology of chronic hepatitis C: patients are older and at a more advanced stage at the time of diagnosis.

INTRODUCTION AND AIM: Over the years, there has been a change in the profile of patients with chronic hepatitis C (CHC). In recent years, more patients with CHC have presented to the clinics at the cirrhotic stage, with decompensated liver disease, and with hepatocellular carcinoma. The aim of this study was to investigate the changing epidemiological, clinical, and virological characteristics of CHC patients. PATIENTS AND METHODS: A total of 313 CHC patients were included in this study. The patients were classified into group 1 (1996-2001) and group 2 (2011-2016). Epidemiological, clinical, and virological differences were investigated between two periods. RESULTS: Overall, 44.7% (n = 140) of the patients were in group 1. The sex distribution between the two groups was similar. The patients in group 2 was older than those in group 1 (54 ± 15 vs. 45 ± 12 years, retrospectively, P < 0.001). Whereas 19.8% of the patients in group 1 were treatment-experienced, this rate was found to be 35.5% in group 2 (P = 0.01). Patients who presented in the first period had fewer comorbidities compared with group 2 (P < 0.001). More patients in group 2 had liver cirrhosis than group 1 (45.1 vs. 18.6%, respectively, P < 0.001). Among the patients with cirrhosis, the rate of decompensation was higher in group 2 (46.7 vs. 23.3%, P = 0.03). The presence of hepatocellular carcinoma was significantly higher in group 2 than group 1 (12.8 vs. 3.6%, respectively, P = 0.004). CONCLUSION: In recent years, CHC patients have presented to hospitals with advanced stage of liver disease; these patients are older and have more comorbidities.

Low recurrence rate of hepatocellular carcinoma following ledipasvir and sofosbuvir treatment in a real-world chronic hepatitis C patients cohort.

The aims of the present study were to evaluate the efficacy and tolerability of ledipasvir/sofosbuvir (LDV/SOF) with or without ribavirin in the treatment of chronic hepatitis C (CHC) in patients with advanced liver disease and to analyse whether the use of LDV/SOF treatment is associated with a new occurrence of hepatocellular carcinoma (HCC) during and after LDV/SOF treatment. The Turkish Early Access Program provided LDV/SOF treatment to a total of 200 eligible CHC patients with advanced liver disease. The median follow-up period was 22 months. All patients were Caucasian, 84% were infected with genotype 1b, and 24% had a liver transplantation before treatment. The sustained virological response (SVR12) was 86.0% with ITT analysis. SVR12 was similar among patients with Child-Pugh classes A, B and C disease and transplant recipients. From baseline to SVR12, serum ALT level and MELD score were significantly improved (P < 0.001). LDV/SOF treatment was generally well tolerated. Only one patient developed a new diagnosed HCC. Seventeen of the 35 patients, who had a history of previous HCC, developed HCC recurrence during the LDV/SOF treatment or by a median follow-up of 6 months after treatment. HCC recurrence was less commonly observed in patients who received curative treatment for HCC compared with those patients who received noncurative treatment (P = 0.007). In conclusion, LDV/SOF with or without ribavirin is an effective and tolerable treatment in CHC patients with advanced liver disease. Eradication is associated with improvements in liver function and a reduced risk of developing a new occurrence of HCC.

Brucellosis as the Cause of Non-Viral Bacterial Hepatitis: A Case Report.

BACKGROUND: Brucellosis can lead to different clinical pictures such as hepatomegaly, granulomatous liver disease, hepatic abscess, and it can cause mild hepatic transaminase elevation in the laboratory investigations. CASE REPORT: We found out that the etiologic agent was Brucella in our two cases admitted with acute hepatitis presentation in the investigations conducted. Liver transaminases were as follows for case 1 and case 2; AST: 306/187U/L, ALT: 368/312U/L, ALP: 355/264U/L, GGT: 116/197U/L, LDH: 887/549U/L, respectively. Sacroiliitis also accompanied the clinical picture in our first case. Our patients showed clinical and laboratory improvement with rifampicin, doxycycline, (additional streptomycin for 21 days in the patient with sacroiliitis) treatment. CONCLUSION: Brucellosis which may manifest as a clinical picture regarding numerous medical branches should be considered in case of acute hepatitis, especially in endemic regions, along with viral hepatitis.
