Are There Differences in the Management of Acute Pancreatitis Cases Due to Severe Hypertriglyceridemia in Pregnant Women?

BACKGROUND The aim of this study was to determine the prognosis of severe disease and treatment approaches of both normal and pregnant, especially in patients with severe pancreatitis due to hypertriglyceridemia. MATERIAL AND METHODS We included 30 patients (20 females and 10 males) in this study whose follow-ups and treatments were performed after a diagnosis of hypertriglyceridemia-induced acute pancreatitis between January 2011 and May 2017. Patient personal information, such as age, sex, pre-treatment and post-treatment triglyceride levels, receipt of anti-hyperlipidemic treatments or plasmapheresis, and family history, were collected from hospital records and patient files. Patients with severe pancreatitis history, score, and prognosis were included to increase the value of our study. Mild and moderate cases were excluded. RESULTS The mean age of the patients was 35±6 years. Twenty-four patients (80%) received an anti-hyperlipidemic treatment before their pancreatitis attacks. Plasmapheresis was performed on 8 patients before their pancreatitis attacks. Eighteen patients (60%) had a family history suggesting familial hypertriglyceridemia. Twelve patients (40%) were pregnant. CONCLUSIONS The treatment of hypertriglyceridemia-induced acute pancreatitis was mostly confined to supportive, palliative treatments. However, plasmapheresis is a possible treatment option and should be used in the early stages of this disease. The response to medical treatment and support treatment was better in pregnant patients than in the other patient group, and pregnant patients did not require plasmapheresis.

An Overlooked Potentially Treatable Disorder: Idiopathic Mesenteric Panniculitis.

OBJECTIVE: The aim of this study was to determine the prevalence of mesenteric panniculitis (MP) and to describe its clinical characteristics, therapy, and outcome. SUBJECTS AND METHODS: This retrospective study was carried out among patients with MP based on computed tomography (CT) scans from January 2012 to December 2015. The CT images were reanalyzed by study radiologists to confirm the previous MP diagnosis. Patients were divided into 2 groups, i.e., idiopathic and secondary, based on the presence or absence of associated predisposing factors such as trauma, malignancy, autoimmune disorders, ischemia, or previous abdominal surgery. The clinical characteristics of the 2 groups, as well as treatments, were assessed. RESULTS: Among the 19,869 CT scans, 36 patients (0.18%) with MP were identified (i.e., 19 [53%] females and 17 [47%] males). The median age was 54 years (range 26 - 76). Twenty-four patients (67%) were categorized into the idiopathic group. Malignancy was the predisposing factor in 8 (22%) of those patients. Furthermore, abdominal pain was the cardinal symptom observed in 22 patients (92%) in the idiopathic group. In the idiopathic group, 15 patients (63%) were treated with antibiotics and 16 (67%) were treated with nonsteroidal anti-inflammatory drugs (NSAID). One unresponsive patient was treated with colchicine. Symptomatic relief was achieved in all of the treated patients. CONCLUSION: In this study, a symptomatic idiopathic subgroup of patients with MP did not have any associated disorder. The response to treatment with antibiotics and NSAID was effective in most of the patients. Based on these findings, anti-inflammatory treatments beyond NSAID and surgery should be reserved for patients who are unresponsive to antibiotics and NSAID.

Unusual presentation; seeding of tumor after biopsy for hepatocellular carcinoma.

Hepatocellular cancer is one of the most common and fatal cancer tumor worldwide. However, the obtained results are questionable in terms of medical treatment of hepatocellular cancer. The muscle, soft tissue and cutaneous metastases of hepatocellular cancer, for instance, are rare and may result from interventional procedures. Seeding of tumor along the biopsy needle upon percutaneous biopsy is a very rare phenomenon. We report a very rare case of a 79 -year- old man, known to be hepatitis C virus carrier with a metastatic tumor in abdominal wall caused by seeding of tumor after three years following a percutaneous biopsy procedure. Even years later, after a biopsy procedure for diagnostic purposes and may be soft tissue metastases. This complication is a very rare condition that should not be ignored but can be observed. The biopsy requirement should be questioned closely and avoided unnecessary biopsy procedures.

Assessment of Liver Fibrosis with Diffusion-Weighted Magnetic Resonance Imaging Using Different b-values in Chronic Viral Hepatitis.

OBJECTIVE: To examine the effectiveness of apparent diffusion coefficient (ADC) values and to compare the reliability of different b-values in detecting and identifying significant liver fibrosis. SUBJECTS AND METHODS: There were 44 patients with chronic viral hepatitis (CVH) in the study group and 30 healthy participants in the control group. Diffusion-weighted magnetic resonance imaging (DWI) was performed before the liver biopsy in patients with CVH. The values of ADC were measured with 3 different b-values (100, 600, 1,000 s/mm2). In addition, liver fibrosis was classified using the modified Ishak scoring system. Liver fibrosis stages and ADC values were compared using areas under the receiver-operating characteristic (ROC) curve. RESULTS: The study group's mean ADC value was not statistically significantly different from the control group's mean ADC value at b = 100 s/mm2 (3.69 ± 0.5 × 10-3 vs. 3.7 ± 0.3 × 10-3 mm2/s) and b = 600 s/mm2 (2.40 ± 0.3 × 10-3 vs. 2.5 ± 0.5 × 10-3 mm2/s). However, the study group's mean ADC value (0.99 ± 0.3 × 10-3 mm2/s) was significantly lower than that of the control group (1.2 ± 0.1 × 10-3 mm2/s) at b = 1,000 s/mm2. With b = 1,000 s/mm2 and the cutoff ADC value of 0.0011 mm2/s for the diagnosis of liver fibrosis, the mean area under the ROC curve was 0.702 ± 0.07 (p = 0.0015). For b = 1,000 s/mm2 and the cutoff ADC value of 0.0011 mm2/s to diagnose significant liver fibrosis (Ishak score = 3), the mean area under the ROC curve was 0.759 ± 0.07 (p = 0.0001). CONCLUSION: Measurement of ADC values by DWI was effective in detecting liver fibrosis and accurately identifying significant liver fibrosis when a b-value of 1,000 s/mm2 was used.

Pistacia Terebinthus Coffee Protects against Thioacetamide-Induced Liver Injury in Rats.

AIM/BACKGROUND: Pistacia terebinthus is used as a coffee substitute in the East and Southern Anatolia regions of Turkey. It contains unsaturated fatty acids, tocopherols, polyphenols and carotenoids. P. terebinthus has anti-inflammatory and potential antioxidant activity. In this study we evaluated the protective effects of P. terebinthus coffee (PTC) on thioacetamide (TAA)-induced liver injury in rats. MATERIALS AND METHODS: Twenty-eight male Sprague-Dawley rats were equally randomized into four groups. Chronic liver injury was induced with TAA (100 mg/kg i.p. three times weekly). The first group of rats served as control and received only tap water (G1), and the remaining groups of rats received PTC, p.o (G2); TAA (G3); TAA plus PTC, p.o (G4), respectively. RESULTS: After 8 weeks, PTC intake significantly reduced fibrosis/inflammation scores (p PTC intake reduced transforming growth factor beta (TGF-ß) concentrations in the liver (p PTC intake. DISCUSSION AND CONCLUSION: PTC intake provided beneficial effects against TAA-induced liver injury in rats. PTC probably suppresses the proinflammatory cytokines through NF-κB signaling pathway.

Gastroesophageal reflux after per-oral endoscopic myotomy: Management literature.

In this editorial, we respond to a review article by Nabi et al, in which the authors discussed gastroesophageal reflux (GER) following peroral endoscopic myotomy (POEM). POEM is presently the primary therapeutic option for achalasia, which is both safe and effective. A few adverse effects were documented after POEM, including GER. The diagnostic criteria were not clear enough because approximately 60% of patients have a long acid exposure time, while only 10% experience reflux symptoms. Multiple predictors of high disease incidence have been identified, including old age, female sex, obesity, and a baseline lower esophageal sphincter pressure of less than 45 mmHg. Some technical steps during the procedure, such as a lengthy or full-thickness myotomy, may further enhance the risk. Proton pump inhibitors are currently the first line of treatment. Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method, such as peroral endoscopic fundoplication or transoral incisionless fundoplication. However, more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them.

Favourable effects of whey protein on acetic acid-induced ulcerative colitis in a rat model.

Introduction: In the present study, we aimed to examine the effects of the administration of whey protein through rectal enema to rats with acetic acid-induced ulcerative colitis on the pathways of nuclear-related factor-2 (Nrf-2), haem oxygenase-1 (HO-1), nuclear factor κB (NF-κB), active protein kinase-1 (AP-1), tumour necrotising factor-α (TNF-α), and cyclooxygenase-2 (COX-2), IL-6, IL-10. Material and methods: Twenty-eight rats were employed for the trial. Ulcerative colitis was induced through the use of acetic acid. The therapeutic doses of whey protein were administered rectally. Ulcerative colitis was subjected to histopathological examination and protein levels in colon tissue were measured with the Western blot method. Results: The significant increases observed in the levels of AP-1, COX-2, IL-6, IL-10, NF-κB, and TNF-α as markers of inflammation following the development of ulcerative colitis showed remarkable decreases along with the administration of whey protein (p < 0.05). On the other hand, we identified a decrease in the Nrf2-ARE signal pathway and HO-1 protein having protective roles in the colon inflammatory response along with the development of ulcerative colitis and activation of the Nrf2-HO-1 pathway by the whey protein. Conclusions: Whey protein modulates Nrf2/HO-1 and NF-kB pathways, thereby creating a therapeutic effect against colonic inflammation induced by acetic acid (AA) due to its anti-inflammatory effects.

Epigallocatechin gallate attenuates experimental non-alcoholic steatohepatitis induced by high fat diet.

BACKGROUND AND AIM: In the present study, we examined the preventive role of epigallocatechin gallate (EGCG) in an experimental non-alcoholic steatohepatitis model induced by a high fat diet. METHODS: The study included 21 male Sprague-Dawley rats, which were equally divided into three groups. The first group was fed on a standard rat diet, the second group on a high fat diet (HFD), and the third group on a HFD + EGCG. The study concluded after 6 weeks. Histopathological examination was performed. Plasma and tissue MDA levels, glucose, insulin, alanine aminotransferase (ALT), aspartate aminotransferase, gamma glutamyltransferase, alkaline phosphatase, triglyceride, and cholesterol levels were studied. Insulin resistance was calculated by the homeostasis model of insulin resistance method. RESULTS: Steatosis, inflammation, ballooning degeneration, and necrosis increased significantly in the HFD group, compared to the control group (P < 0.01). Steatosis and inflammation decreased in the HFD + EGCG group, in comparison to the HFD group (P < 0.05, for each). There was a significant decline in ALT (P < 0.01), triglyceride (P < 0.01), insulin (P < 0.05), and glucose (P < 0.05) levels in the HFD + EGCG group, when compared to the HFD group. Plasma and liver MDA levels in the HFD + EGCG group were lower than those of the HFD group; the difference was significant (P < 0.01 for each). Glutathione levels in the HFD + EGCG group was significantly higher those in the HFD group. CYP 2E1 and alpha-smooth muscle actin expression decreased in the HFD + EGCG group, in comparison to the HFD group (P < 0.01, P < 0.05, respectively). CONCLUSION: EGCG reduces the development of experimental non-alcoholic steatohepatitis induced by a high fat diet. It seems to exercise this effect through its effect on lipid metabolism and antioxidant characteristics.

Effect of unfiltered coffee on carbon tetrachloride-induced liver injury in rats.

To assess the role of unfiltered coffee upon carbon tetrachloride (CCl(4)) induced hepatotoxicity in rats. All rats were randomly divided into control group, CCl(4)-treated, unfiltered coffee-treated and CCl(4)/unfiltered coffee-treated. Hepatic damage was induced by repeated intraperitoneal injections of CCl(4) every other day. Unfiltered coffee was given as drinking fluid for 8 days starting the day before CCl(4) administration. Liver enzymes, plasma and liver tissue malondialdehyde were analyzed. Histopathological evaluation of liver sections was performed. Serum aminotransferase level significantly increased in CCl(4)/unfiltered coffee-treated group compared to CCl(4)-treated group, as well as, lipid peroxidation products in the plasma and liver tissue. In addition, histopathological findings including inflammation and necrosis were significantly confirmed these findings. Unfiltered coffee potentiates acute liver injury in rats with CCl(4)-induced hepatotoxicity.

The treatment with antibody of TNF-alpha reduces the inflammation, necrosis and fibrosis in the non-alcoholic steatohepatitis induced by methionine- and choline-deficient diet.

To assess the effects of anti-TNF-alpha antibody (infliximab) in experimental steatohepatitis induced by methionine- and choline-deficient (MCD) diet. The study included thirty rats. One group received normal rat food, and two groups received MCD diet. The treatment group received a single dose intra-peritoneal infliximab (4 mg/kg), at week 8. MCD diet increased levels of AST, ALT, TNF-alpha, TGF-beta(1), tissue and plasma MDA (p < 0.05 for each). Moreover, it led to steatosis, ballooning degeneration, inflammation, fibrosis and increased actin expression, histopathologically (p < 0.05 for each). In this experimental steatohepatitis anti-TNF-alpha antibody decreased the levels of AST, ALT, TGF-beta(1) and plasma and tissue MDA (p < 0.05 for each). Moreover, inflammation, necrosis, actin expression and fibrosis decreased in anti-TNF-alpha group compared to placebo group (p < 0.05 for each). This study indicates that anti-TNF-alpha antibody is effective on necrosis, inflammation and fibrosis in the experimental model of non-alcoholic steatohepatitis, induced by MCD diet.

Hepatoprotective effect of infliximab, an anti-TNF-alpha agent, on carbon tetrachloride-induced hepatic fibrosis.

To assess the effect of infliximab, an anti-tumor necrosis factor (TNF)-alpha agent, on the carbon tetrachloride (CCl(4))-induced hepatic fibrosis in rats. Rats were randomized into three groups (n=9). The control group received only intraperitoneal (i.p.) olive oil. Hepatic fibrosis was induced by repeated i.p. injections of 1.5 ml/kg CCl(4) (1:3 mixture with olive oil) for 5 weeks in the remaining two groups which were also injected subcutaneous saline or 2 mg/kg infliximab. Infliximab reduced the levels of aspartate aminotransferase and alanine aminotransferase (p<0.05 for both). The scores of hepatic necrosis, inflammation and fibrosis, and expression of alpha-smooth muscle actin were lower in the infliximab-treated group than the CCI(4)-treated group (p<0.01, p<0.001, p<0.01, p<0.001, respectively). However, there was no significant difference in terms of liver tissue and plasma malondialdehyde, and serum TNF-alpha levels, while infliximab relatively reduced the level of transforming growth factor-beta(1) (373.0+/-153.1 vs. 280.8+/-127.1 pg/ml). Treatment with infliximab attenuated the necro-inflammation and fibrogenesis in the CCI(4)-induced hepatic fibrosis, and thus it might be effective as a therapeutic anti-fibrotic agent.

Hematological Indices in Portal Hypertension: Cirrhosis versus Noncirrhotic Portal Hypertension.

Portal hypertension (PHT) leads to several alterations on hematological indices (HI). The aim of the study is to investigate the differences in HI between cirrhotic subjects and subjects who have noncirrhotic PHT (NCPHT). This retrospective study included 328 patients with PHT (239 cirrhosis and 89 NCPHT). Demographic and clinical features, endoscopic and radiological findings, and HI including neutrophil to lymphocyte ratio (NLR) at the time of PHT diagnosis were recorded. Severity of cirrhosis was assessed according to the Child⁻Turcotte⁻Pugh (CTP) classification and Model for End-Stage Liver Disease (MELD) scores. Hematological abnormalities were found in 92.5% of cirrhotic patients and in 55.1% of patients with NCPHT (p < 0.001). While thrombocytopenia was the most common HI in patients with cirrhosis, anemia was the most prevalent HI in NCPHT group. In the cirrhotic group, the NLR was the only parameter to differentiate each CTP group from two others. The NLR value increased with the severity of cirrhosis (2.28 ± 0.14 in CTP-A, 2.85 ± 0.19 in CTP-B and 3.26 ± 0.37 in CTP-C). The AUROC of NLR was 0.692 for differentiating compensated cirrhotic patients from decompensated. Hematological abnormalities are more prevalent and more severe in cirrhotic patients compared to patients with NCPHT. NLR may be used to assess the severity of cirrhosis.

Is ischemia-modified albumin a reliable tool for the assessment of acute pancreatitis?

PURPOSE: Oxidative stress has been implicated in several disorders, including acute pancreatitis (AP). Ischemia-modified albumin (IMA), which reflects the ability to bind cobalt, has been found to be elevated in conditions of oxidative stress and tissue hypoxia. This study examined IMA and adjusted IMA levels in patients with AP, and examined the associations of IMA and adjusted IMA levels to the severity of AP. PATIENTS AND METHODS: A total of 42 consecutive patients with AP and 43 age- and sex-matched control subjects were enrolled. Serum samples were obtained from patients with AP on admission as well as 48-72 hours after hospitalization, and from the controls, at the time of enrollment. Adjusted IMA was calculated by multiplying the IMA value of each patient with the ratio of the patient's albumin value and the median albumin value of the study population. The severity of AP was assessed according to the modified Atlanta classification, and the patients were divided into 2 groups: mild AP and severe AP. RESULTS: The serum IMA and adjusted IMA values of patients with AP on admission and those of the controls did not differ (p=0.86 and p=0.99, respectively). The second measurements of IMA and adjusted IMA in the AP group were higher than the first measurements of both the AP group and controls (for all, p<0.01). Among the IMA measurements, only adjusted IMA on admission had the ability to predict the severity of AP. Severe AP was correlated with albumin, and the area under the curve of adjusted IMA values on admission was 0.746 for differentiating patients with severe AP from mild AP with statistical significance (p=0.005). CONCLUSION: It was shown that IMA and adjusted IMA levels rise with the progression of AP. Lower levels of adjusted IMA predict the severity of AP. Further studies with serial measurements of IMA are warranted to explore the indicative role of IMA in the course of AP.

An unusual case of hematemesis and epistaxis caused by a pheochromocytoma.

Pheochromocytoma is a rare catecholamine-secreting neoplasm that is the cause of hypertension in <0.2% of patients with hypertension. We encountered an unusual case of pheochromocytoma involving hematemesis and epistaxis episodes with accompanying hypertensive attacks. Venous ectasia was detected in the esophagus. Abdominal magnetic resonance imaging revealed an adenoma in the left adrenal region. The present case illustrates that pheochromocytoma can mimic different clinical conditions.

Anti-HDV seroprevalance among patients with previous HBV infection.

OBJECTIVE: This prospective study aimed to determine the prevalence of anti-HDV seropositivity among subjects who had previous hepatitis B virus (HBV) infection. METHODS: Subjects who were admitted to the gastroenterology inpatient clinic of our hospital between August 2016 and July 2017 were screened for previous HBV infection. The subjects who had HBV serology compatible with resolved HBV infection were recruited in the study, and the seroprevalance of anti-HDV was studied. Participants answered a short questionnaire regarding their family history of chronic hepatitis B (CHB) and chronic hepatitis D (CHD) infection and risk factors for transmission. Subjects who were anti-HDV positive were recalled for a control visit, and HBV-DNA and HDV-RNA were assayed in the blood samples of the responders. RESULTS: Among 554 subjects who had previous HBV infection, 53 (9.6%) were anti-HDV positive. The mean age was 63.1±15.4 years in the anti-HDV-positive group and 65.9±15.6 years in the anti-HDV-negative group (p=0.19). The most common risk factor for both groups was dental procedures (89% vs 80%, p=0.33). Anti-Hbc IgG, anti-Hbs, and anti-HBeAg seropositivity did not differ between the anti-HDV-positive and -negative groups (for all, p>0.05). Although HDV-RNA was not detectable in all studied samples, only one subject had detectable HBV-DNA in the anti-HDV-positive group. CONCLUSION: This study highlighted the prevalence of anti-HDV among subjects who had resolved HBV infection. Long-term follow-up studies, including after the resolution of both infections, are needed to explore HBV-HDV interactions and the behavioral patterns of these viruses.

A Neglected Issue in Ulcerative Colitis: Mesenteric Lymph Nodes.

Data evaluating the presence and characteristics of mesenteric lymph nodes (LNs) in patients with ulcerative colitis (UC) are scarce. The aim of this study is to determine the presence and characteristics of LNs in UC. The LN characteristics in computed tomography (CT), including LN dimension and attenuation, were evaluated retrospectively in 100 patients with UC (61 active and 39 inactive cases). Clinical characteristics and laboratory parameters, including CBC, biochemical analysis, erythrocyte sedimentation rate (ESR), and C reactive protein (CRP) were also compared. Mesenteric LNs were evident in all patients with UC. The attenuation and dimension of mesenteric LNs did not differ between active and inactive patients with UC. No correlation was found among patients with UC in terms of LN dimension, attenuation, ESR, CRP, leucocyte, and albumin (all with p > 0.05). The current study suggested that inflammation results in the development of mesenteric LN in UC, similar to Crohn’s disease and other inflammatory disorders.

Protective role of genistein in acute liver damage induced by carbon tetrachloride.

AIM: In the present study, we investigated the protective effect of genistein in experimental acute liver damage induced by CCl4. METHOD: Forty rats were equally allocated to 5 groups. The first group was designated as the control group (group 1). The second group was injected with intraperitoneal CCl4 for 3 days (group 2). The third group was injected with subcutaneous 1 mg/kg genistein for 4 days starting one day before CCl4 injection. The fourth group was injected with intraperitoneal CCl4 for 7 days. The fifth group was injected with subcutaneous 1 mg/kg genistein for 8 days starting one day before CCl4 injection. Plasma and liver tissue malondialdehyde (MDA) and liver glutathione levels, as well as AST and ALT levels were studied. A histopathological examination was conducted. RESULTS: Liver tissue MDA levels were found significantly lower in group 3, in comparison to group 2 (P < .05). Liver tissue MDA level in group 5 was significantly lower than that in group 4 (P < .001). Liver tissue glutathione levels were higher in group 5 and 3, relative to groups 4 and 2, respectively (P > .05 for each). Inflammation and focal necrosis decreased in group 3, in comparison to group 2 (P < .001 for each). Inflammation and focal necrosis in group 5 was lower than that in group 4 (P < .001). Actin expression decreased significantly in group 5, relative to group 4 (P < .05). CONCLUSION: Genistein has anti-inflammatory and antinecrotic effects on experimental liver damage caused by CCl4. Genistein reduces liver damage by preventing lipid peroxidation and strengthening antioxidant systems.

Portal hypertension due to Echinococcus alveolaris: a case report.

Infection of the liver with Echinococcus alveolaris (EA) contemplates with a fatal course though it is a rare condition. We present herein a patient with upper gastrointestinal bleeding due to portal hypertension caused by the involvement of the liver with EA.

Fasciola hepatica case with hemobilia.

Fasciola hepatica (FH) can lead to important hepatobiliary diseases. Here we present a case of hemobilia associated with biliary FH, which is quite a rare case. The 41-year-old patient, who underwent common bile duct exploration due to hemobilia, was found to have arterial bleeding associated with ulcer caused by a dead parasite in the common bile duct. Hemobilia is a very rare complication associated with FH. When searching for the cause of hemobilia, FH should be considered.

Treatment of Delta Hepatitis: Today and in the Future - A review.

Hepatitis delta virus (HDV) is a defective satellite virus and propagates in the presence of Hepatitis B virus (HBV) surface antigen (HBsAg). Approximately 5% of the people who infected with HBV are also infected with HDV. Chronic hepatitis caused by delta is the most severe form of chronic viral hepatitis including accelerated fibrosis, liver decompensation and development of hepatocellular carcinoma. Interferon-based therapies still remain the only treatment option of the hepatitis delta. The beneficiary effects of the interferon-based therapies, however, stop frequently with termination of the given therapy and relapse rate is very high. Accordingly, the efficiency rate of this treatment does not exceed 30%. On the other hand, serious side effects of interferons are another troublesome leading to withdrawal of the therapy. The main goal of the current treatments is clearance of HBsAg. There is no available drug acting directly against the HDV. New therapies interacting with HDV life cycle are under investigation. While prenylation inhibitors act on merely HDV, viral entry inhibitors and HBsAg release inhibitors would be used in the treatment of both HBV and HDV. We hope that in the future, the use of novel therapies and HBV vaccination provide to clinicians to cope with this troublesome agent.
