Different Food Preferences in Patients with Gastrointestinal Disorders.

Objective Gastrointestinal (GI) disorders such as functional dyspepsia (FD), irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), and inflammatory bowel disease (IBD) can exhibit overlapping GI symptoms, including abdominal pain and alterations in bowel habits. The symptoms of GI disorders are commonly considered to be triggered and exacerbated by fatty food intake. Therefore, this study aimed to compare the food preferences of patients with GI disorders. Methods Forty food images (including fatty and light foods) and 20 animal images were selected to evaluate food preferences. The preference score was assessed using a visual analog scale ranging from 1 to 100. GI symptoms were evaluated using the GI Symptom Rating Scale (GSRS), and correlations between the GSRS and preference scores were investigated. Results Overall, 22 healthy controls and 23, 29, 27, and 20 patients with FD, IBS, GERD, and IBD, respectively, were enrolled. The preference score for all foods in patients with FD was significantly lower than that in healthy controls and those with IBS, GERD, and IBD (52.9 vs. 66.5 vs. 68.5 vs. 69.1 vs. 70.7, p<0.01). The score of fatty foods was lower in patients with FD than in healthy controls and those with IBS, GERD, and IBD (43.8 vs. 72.3 vs. 77.5 vs. 77.4 vs. 80.7, p<0.01), whereas that of light foods and animal images was not different among the groups. No significant correlation was found between the preference score and symptom severity. Conclusions Patients with FD had a negative preference for foods, particularly fatty foods, independent of the severity of GI symptoms.

A Case of Idiopathic Peptic Ulcer Disease Treated Effectively with Trimebutine Maleat.

A 30-year-old man with idiopathic peptic ulcer disease (IPUD) experienced repeated recurrence of ulcerative bleeding despite treatment with lansoprazole and then vonoprazan. Further evaluation suggested that the cause of the ulcer was strong contractile movements of the antrum. This prompted the co-administration of trimebutine maleate (TM) and vonoprazan to relieve the stomach contractions. TM was effective in preventing the recurrence of ulcerative bleeding, and the patient has remained in remission for 4 years. This case highlights the potential efficacy of TM in treating IPUD and the importance of considering hypercontractility as the underlying cause in cases of IPUD.

Brain activity in response to food images in patients with irritable bowel syndrome and functional dyspepsia.

BACKGROUND: Functional dyspepsia (FD) and irritable bowel syndrome (IBS) are caused and exacerbated by consumption of fatty foods. However, no study has evaluated brain activity in response to food images in patients with disorders of gut-brain interaction (DGBI). This study aimed to compare food preference and brain activity when viewing food images between patients with DGBI and healthy controls. METHODS: FD and IBS were diagnosed using the ROME IV criteria. Food preference was assessed using a visual analog scale (VAS). Brain activity in the prefrontal cortex (PFC) in response to food images was investigated using functional near-infrared spectroscopy (fNIRS). RESULTS: Forty-one patients were enrolled, including 25 with DGBI. The mean VAS scores for all foods (controls vs. FD vs. IBS: 69.1 ± 3.3 vs. 54.8 ± 3.8 vs. 62.8 ± 3.7, p = 0.02), including fatty foods (78.1 ± 5.4 vs. 43.4 ± 6.3 vs. 64.7 ± 6.1, p < 0.01), were the lowest in patients with FD among all groups. Patients with FD had significantly higher brain activity in the left PFC than those with IBS and healthy controls (mean z-scores in controls vs. FD vs. IBS: - 0.077 ± 0.03 vs. 0.125 ± 0.04 vs. - 0.002 ± 0.03, p < 0.001). CONCLUSIONS: Patients with DGBI, particularly those with FD, disliked fatty foods. The brain activity in patients with DGBI differed from that in healthy controls. Increased activity in the PFC of patients with FD was confirmed.

Efficacy of endoscopic ultrasound-guided abscess drainage for non-pancreatic abscesses: A retrospective study.

Background and Aim: Percutaneous drainage of intra-abdominal abscesses is often uncomfortable for the patient and may result in prolonged hospital stays. Recent studies have shown that endoscopic ultrasound-guided abscess drainage (EUS-AD) could effectively treat various abscesses and fluid collections. However, no indications or procedures have been established for EUS-AD treatments, and studies on its usefulness and safety are insufficient. The present study aimed to evaluate the efficacy and safety of EUS-AD for treating non-pancreatic abscesses. Methods: This retrospective study included 20 patients, aged ≥20 years, who underwent EUS-AD for an abscess or fluid accumulation in the abdomen or mediastinum, but not the pancreas. Patients were treated at the Kawasaki University General Medical Center between March 2013 and June 2021. All EUS-AD procedures were performed prior to a percutaneous drainage or surgical drainage. Results: Among the 20 patients who underwent an EUS-AD for abscess, 8 (40%) had liver abscesses, 6 (30%) had intraperitoneal abscesses, 3 had (15%) splenic abscesses, 1 (5%) had a mediastinal abscess, 1 (5%) had an iliopsoas abscess (n = 1, 5%), and 1 (5%) had an abdominal wall abscess. The technical success rate was 95% (n = 19/20). We inserted nasobiliary catheters in 4/20 patients (20%). The clinical success rate was 90% (n = 18/20). Two clinical failures required reintervention, and both were treated with percutaneous drainage. Adverse events were observed in 2/20 patients (10%). One patient experienced fever after the procedure, and the other experienced localized peritonitis. Conclusion: EUS-AD was effective and safe for abscess removal, particularly when approached from the upper gastrointestinal tract.

Soluble CD163 is a predictor of fibrosis and hepatocellular carcinoma development in nonalcoholic steatohepatitis.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease. The serum level of soluble CD163 (sCD163), a macrophage activation marker, is associated with liver tissue changes; however, its prognostic value is unknown. Here, we determined the utility of sCD163 as a marker for hepatocellular carcinoma (HCC) and prognostic marker for NAFLD. METHODS: This retrospective study obtained data regarding serum sCD163 levels, liver histology, and background factors associated with NAFLD in 287 patients (men/women, 140/147; average age, 53 ± 14 years) with NAFLD who underwent liver biopsy. Repeated liver biopsies of 287 patients with NAFLD (5.0 ± 2.7 years) were compared regarding serum sCD163 levels and liver tissue changes (stage, grade, steatosis, and NAFLD activity score). RESULTS: Serum sCD163 levels increased with the progression of liver fibrosis and inflammation (both P < 0.05) and were particularly helpful in distinguishing cases of Grade 4 fibrosis (P < 0.001). Levels of sCD163 significantly decreased in patients with NAFLD exhibiting alleviated fibrosis and inflammation (P < 0.05). We could also predict the development of HCC and associated mortality based on serum sCD163 levels at the time of NAFLD diagnosis. Serum sCD163 levels were higher in patients with HCC than in patients without HCC (1074 ± 379 ng/ml vs. 669 ± 261 ng/ml; P < 0.0001), and the same trend was observed for mortality. CONCLUSIONS: The serum sCD163 level reflects the progression of fibrosis and inflammation in liver tissues, showing much promise as a noninvasive biomarker for nonalcoholic steatohepatitis and NAFLD as well as a possible predictor of HCC development and patient prognosis.

Lean nonalcoholic fatty liver disease: Age-dependent differences in pathology, prognosis, and liver-related events.

AIM: This study aimed to evaluate the age-specific characteristics, prognosis, and complications of patients with lean nonalcoholic fatty liver disease (NAFLD). METHODS: Background factors (age, sex, diabetes, dyslipidemia, hypertension, and PNPLA3 gene polymorphism), blood test results, liver histology findings, muscle mass, and grip strength were investigated in 782 patients with NAFLD who underwent liver biopsy. Prognosis and complications were compared among 549 patients with nonlean or lean NAFLD who were followed up for 6.5 years. Additionally, background factors, blood test results, liver histology findings, prognosis, and complications were compared according to age (≥60 years vs. <60 years) in patients with lean NAFLD. RESULTS: Lean NAFLD patients showed lower aspartate aminotransferase, alanine aminotransferase, homeostasis model assessment-insulin resistance, high-sensitivity C-reactive protein, ferritin, and leptin but higher adiponectin and hemoglobin A1c (HbA1c) levels than patients with nonlean NAFLD. Furthermore, lean NAFLD patients showed less liver fibrosis, inflammation, steatosis, and ballooning. Among lean NAFLD patients, those aged 60 years and older were more frequently female, showed higher rates of hypertension, diabetes, and dyslipidemia, had higher HbA1c and type IV collagen 7S levels, lower platelet count, higher liver fibrosis and inflammation grades, and lower muscle mass and grip strength. Lean NAFLD was associated with a worse prognosis in patients aged 60 years and over than in those younger than 60 years of age and with a higher incidence of liver-related disease, cerebrocardiovascular events, and nonliver cancer. CONCLUSIONS: Age is an important consideration in patients with lean NAFLD. Compared with nonlean NAFLD, lean NAFLD was associated with a worse prognosis and higher risk of complications in patients aged 60 years and older.

Two Cases of Acute Gastric Mucosal Lesions Due to Helicobacter pylori Infection Confirmed to be Transient Infection.

Two adult cases of acute gastric mucosal lesions (AGML) caused by Helicobacter pylori infection were confirmed by spontaneous eradication during the follow-up period. The clinical course of the initial infection by H. pylori in adults with AGML remains unclear, whether it is transient or progresses to a persistent infection. In these two reported cases, gastric biopsies at the time of the onset revealed the presence of H. pylori; however, serum H. pylori antibodies performed at the same time were negative. Retesting for H. pylori serum antibody, after six months in one and after two months in the other, was negative, confirming spontaneous eradication.

[Evacuation of tissue and blood biomarkers of progression to NASH cirrhosis by six liver biopsies: a case report].

We present a 56-year-old female patient diagnosed with stage 2/grade 3 non-alcoholic steatohepatitis (NASH) via liver biopsy. Over the next 14 years, six liver biopsies were performed, and the patient was followed up clinically. This was a valuable case wherein we were able to investigate the histology of the liver and the timing of changes in the AST/ALT ratio, platelets, albumin, FIB4-Index, and liver fibrosis markers.

Treatment of ectopic variceal bleeding at choledochojejunostomy by endoscopic glue injection therapy with cyanoacrylate: Report of three cases including long-term outcomes.

Ectopic varices around the choledochojejunostomy site after pancreatoduodenectomy are rare. Diagnosing ectopic varices is difficult but, if untreated or misdiagnosed, the resulting mortality is high. This report describes three cases of ectopic variceal bleeding at the choledochojejunostomy site that were improved by endoscopic glue injection therapy (EGIT) with cyanoacrylate (CA). Case 1 was a 68-year-old man admitted to the hospital with hematemesis and melena. Six years prior, the patient underwent a total pancreatectomy for intraductal papillary mucinous adenocarcinoma. We diagnosed ectopic variceal rupture at the choledochojejunostomy site and controlled bleeding by EGIT with alpha-CA (αCA). Two recurrences of bleeding were improved by EGIT. Case 2 was a 71-year-old man admitted to the hospital with melena. Two and a half years prior, the patient underwent pancreatoduodenectomy for pancreatic head adenocarcinoma. We found the red plug on the ectopic varices at the choledochojejunostomy site through endoscopic observation and performed EGIT with αCA. He had no recurrence. Case 3 was a 77-year-old woman admitted to the hospital with melena. Eleven years prior, the patient underwent pancreatoduodenectomy for chronic pancreatitis at the pancreatic head. We controlled ectopic variceal bleeding at the choledochojejunostomy site by EGIT with αCA. Seven years after EGIT, ectopic varices could not be identified with an endoscope and there was no recurrence of ectopic bleeding.

Afferent-Loop Syndrome Treated with Endoscopic Ultrasound-Guided Drainage of the Afferent Loop with a Plastic Stent.

Afferent-loop syndrome (ALS) is known as a rare complication of partial or total gastrectomy and also occurs after pancreatoduodenectomy. The symptoms of ALS vary with the location of the mechanical obstruction, and the choice of therapeutic method should reflect the patient's condition and disease state. Herein, we report the use of endoscopic ultrasound (EUS)-guided afferent loop drainage with a plastic stent and its reintervention for malignant ALS. An 80-year-old man was admitted to our hospital with abdominal pain. Thirty-two months before, the patient underwent left hepatectomy with choledochojejunostomy and Roux-en-Y reconstruction for hilar biliary adenocarcinoma. An abdominal CT scan showed a dilated afferent loop and a low-density lesion in the peritoneum that suggested recurrence of hilar biliary adenocarcinoma and malignant ALS due to mechanical obstruction of the afferent loop caused by peritoneal dissemination. The recurrence site did not include the choledochojejunostomy anastomosis and was far distal to it. We employed a convex EUS scope and directly punctured the afferent loop from the stomach. We inserted one double pig-tail stent, and the ALS immediately improved. Five months later, ALS recurred, and we exchanged a plastic stent through the fistula. After reintervention, ALS did not recur before the patient's death due to cancer progression.

Efficacy of primary drainage by endoscopic ultrasound-guided biliary drainage for unresectable pancreatic adenocarcinoma.

Background and Aim: Obstructive jaundice induced by pancreatic adenocarcinoma is typically treated with biliary drainage with endoscopic retrograde cholangiopancreatography (ERCP)-guided biliary drainage (ERCP-BD). Recently, endoscopic ultrasonography-guided biliary drainage (EUS-BD) was employed as an alternative method after ERCP-BD failed. We aimed to determine the efficacy and safety of EUS-BD for primary biliary drainage. Methods: Between December 2011 and February 2019, at Kawasaki General Medical Center, we retrospectively enrolled 33 patients who had undergone endoscopic biliary drainage with a metal stent, in a first attempt to relieve obstructive jaundice caused by unresectable pancreatic adenocarcinoma. We compared the technical and clinical outcomes between ERCP-BD and EUS-BD. Results: Twenty-three patients underwent ERCP-BD and 10 underwent EUS-BD. Both groups achieved 100% technical success. The clinical success rates were similar between the groups: 91% (21/23 patients) for ERCP-BD and 100% (10/10 patients) for EUS-BD (P = 0.48). Biliary obstruction recurred in 6/23 patients (26%) treated with ERCP-BD and 1/10 patients (10%) treated with EUS-BD (P = 0.40). Other adverse events occurred in 4/23 patients (17%) in the ERCP-BD group and 1/10 patients (10%) in the EUS-BD group (P = 0.99). Conclusion: We suggest that EUS-BD could be employed for primary biliary drainage in patients with obstructive jaundice caused by unresectable pancreatic adenocarcinoma.

Combination of type IV collagen 7S, albumin concentrations, and platelet count predicts prognosis of non-alcoholic fatty liver disease.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease and affects approximately 25% of the general global adult population. The prognosis of NAFLD patients with advanced liver fibrosis is known to be poor. It is difficult to assess disease progression in all patients with NAFLD; thus, it is necessary to identify patients who will show poor prognosis. AIM: To investigate the efficacy of non-invasive biomarkers for predicting disease progression in patients with NAFLD. METHODS: We investigated biomarkers associated with mortality in patients with NAFLD who visited the Kawasaki Medical School General Medical Center from 1996 to 2018 and underwent liver biopsy and had been followed-up for > 1 year. Cumulative overall mortality and liver-related events during follow-up were calculated using the Kaplan-Meier analysis and compared using log-rank testing. We calculated the odds ratio and performed receiver operating characteristic curve analysis with logistic regression analysis to determine the optimal cut-off value with the highest prognostic ability. RESULTS: We enrolled 489 patients who were followed-up for a period of 1-22.2 years. In total, 13 patients died (2.7% of total patients enrolled); 7 patients died due to liver-related causes. Poor prognosis was associated with liver fibrosis on histological examination but not with inflammation or steatosis. Blood biomarkers associated with mortality were platelet counts, albumin levels, and type IV collagen 7S levels. The optimal cutoff index for predicting total mortality was a platelet count of 15 × 104/µL, albumin level of 3.5 g/dL, and type IV collagen 7S level of 5 mg/dL. In particular, only one-factor patients with NAFLD presenting with platelet counts ≤ 15 × 104/µL, albumin levels ≤ 3.5 g/dL, or type IV collagen 7S ≥ 5 mg/dL showed 5-year, 10-year, and 15-year survival rates of 99.7%, 98.3%, and 94%, respectively. However, patients with two factors had lower 5-year and 10-year survival rates of 98% and 43%, respectively. Similarly, patients with all three factors showed the lowest 5-year and 10-year survival rates of 53% and 26%, respectively. CONCLUSION: A combination of the three non-invasive biomarkers is a useful predictor of NAFLD prognosis and can help identify patients with NAFLD who are at a high risk of all-cause mortality.

Disappearance of Gastric Hyperplastic Polyps after the Discontinuation of Proton Pump Inhibitor in a Patient with Liver Cirrhosis.

Here, we report on a rare case of gastric hyperplastic polyps which disappeared after the discontinuation of proton pump inhibitor (PPI). The patient was an 83-year-old woman with liver cirrhosis and portal hypertension, along with gastroesophageal reflux disease treated by PPI. An initial upper gastrointestinal endoscopy showed unique polypoid lesions in the greater curvature of the stomach. Biopsy specimens of the lesions were diagnosed as hyperplastic polyps and she was followed. One year later, a second endoscopy showed that the lesions had increased in number and size, and an endoscopic mucosal resection (EMR) was performed for the main polyps. The resected specimens indicated a proliferation of foveolar epithelium cells with an increase of capillary ectasia and parietal cell hyperplasia, which was thought to be induced by hypergastrinemia from the PPI. Three months after the EMR, she was admitted because of bleeding from the remaining polyps along with an increase in new polyps. After conservative treatment, PPI was stopped and rebamipide was used. One year and 6 months later, an endoscopy showed the complete disappearance of all gastric polyps.

Gastric Hyperplastic Polyps after Argon Plasma Coagulation for Gastric Antral Vascular Ectasia in Patients with Liver Cirrhosis: A Case Suggesting the "Gastrin Link Theory".

We herein report a case of gastric hyperplastic polyps after argon plasma coagulation (APC) for gastric antral vascular ectasia (GAVE) in the antrum of a 65-year-old man with liver cirrhosis and hypergastrinemia induced by long-term proton pump inhibitor (PPI) use. Two years after APC therapy, endoscopy demonstrated multiple gastric polyps in the antrum and angle. A gastric polyp biopsy indicated foveolar epithelium hyperplasia, which was diagnosed as gastric hyperplastic polyps. One year after switching to an H2 blocker antagonist, endoscopy revealed that the polyps and GAVE had disappeared, with normal gastrin levels suggesting that PPI-induced hypergastrinemia had caused gastric hyperplastic polyps after APC therapy, and the polyps had disappeared after discontinuing PPIs.

Progression from Nonalcoholic Fatty Liver to Nonalcoholic Steatohepatitis Cirrhosis Confirmed by Liver Histology after 14 Years.

A 44-year-old patient progressed from nonalcoholic fatty liver (NAFL) to nonalcoholic steatohepatitis (NASH) cirrhosis. She was diagnosed with NAFL via a liver biopsy. At 56 years old, she was diagnosed with NASH stage 3 via a second liver biopsy. One year later, she was diagnosed with NASH cirrhosis via a third liver biopsy. This is the first study to report the gradual deterioration of liver histology shown via three liver biopsies and fibrosis markers in a patient who progressed from NAFL to NASH cirrhosis. Following menopause, it is necessary to be aware of the rapid development of liver fibrosis.

Fatty Liver, and Not Visceral Fat, Is More Associated with Liver Fibrosis and Diabetes in Non-Obese Japanese Individuals: A Cross-Sectional Study.

Asians are known to be more likely than Westerners to develop fatty liver and lifestyle-related diseases in spite of their weight. However, the relationship between fat accumulation and lifestyle-related diseases in non-obese Asians is unknown. Therefore, this study aimed to analyze visceral fat and hepatic fat in participants with a normal body mass index (BMI) and examine their characteristics during a medical checkup. This cross-sectional study was conducted on 663 of 1142 patients who underwent abdominal ultrasonography and who had an alcohol intake (converted to ethanol) of <30 g/day for males and <20 g/day for females and a BMI of <25 kg/m2 during a health checkup. Participants were classified into four groups: group A, visceral fat accumulation (VFA) (-) and fatty liver (FL) (-) (n = 549); group B, VFA (+) and FL (-) (n = 32); group C, VFA (-) and FL (+) (n = 58); and group D, VFA (+) and FL (+) (n = 24). The frequencies of lifestyle-related disease complications, liver function tests, and liver fibrosis were evaluated among the four groups. Compared with group A (control), groups B, C, and D had a higher number of males, BMI, abdominal circumference, ALT, AST, γ-GTP, triglyceride, uric acid, fasting blood sugar levels, and incidence of hyperlipidemia. Groups C and D had higher ALT, HbA1c, cholinesterase, and triglyceride levels, FIB4 index, and the number of patients with diabetes mellitus (DM) than groups A and B; however, there was no difference between groups A and B. FL is a risk factor of DM and liver fibrosis in non-obese Japanese individuals; however, VFA only is not a risk factor of DM and liver fibrosis.

High Prevalence of Autoimmune Gastritis in Patients with Nonalcoholic Steatohepatitis.

Objective To evaluate the prevalence of autoimmune gastritis in patients with histologically proven nonalcoholic steatohepatitis (NASH). Methods A total of 33 patients with NASH and 143 patients with chronic liver disease (66, 24, 22, 10, 1, and 21 patients with hepatitis C, hepatitis B, autoimmune hepatitis/primary biliary cholangitis, non-B/non-C hepatitis, fatty liver, and alcoholic disease, respectively) who underwent upper gastrointestinal endoscopy between January 2013 and August 2016 were retrospectively assessed to determine the prevalence of autoimmune gastritis. The clinical characteristics of these patients with NASH and autoimmune gastritis were examined, and the clinical characteristic and biomarkers were compared between patients with NASH with and without autoimmune gastritis. Results Six of the 33 patients with NASH (19.4%) were diagnosed with autoimmune gastritis. The prevalence of autoimmune gastritis was higher in patients with NASH than in those with other chronic liver diseases [4/143 (2.8%), p=0.002]. All six patients with NASH and autoimmune gastritis exhibited high serum gastrin levels; five of the patients were positive for anti-parietal cell antibodies, and one was negative for anti-parietal cell antibodies but positive for intrinsic factor antibody. Furthermore, 1 patient presented with iron-deficiency anemia (hemoglobin <11 g/dL), but none developed pernicious anemia. Endocrine cell micronests were found in four patients. Patients with NASH and autoimmune gastritis tended to be older with lower ferritin levels than the other patients. Conclusion The prevalence of NASH with concomitant autoimmune gastritis was high, highlighting the need for upper endoscopy for the diagnosis of autoimmune gastritis and gastric malignancies.

Hypoinsulinemic hypoglycemia triggered by liver injury in elderly subjects with low body weight: case reports.

Hypoglycemia is induced by many causes, especially over-dose of insulin or oral hypoglycemic agents in diabetic subjects. In such a case, hyperinsulinemic hypoglycemia is usually observed. On the other hand, it is important to classify secondary hypoglycemia and hypoinsulinemic hypoglycemia. Liver injury-induced hypoglycemia is one of the causes of hypoinsulinemic hypoglycemia but rarely observed in clinical practice. Herein, we experienced similar 2 cases of non-diabetic hypoinsulinemic hypoglycemia. Both of them were elderly subjects with low body weight. Furthermore, it is likely that hypoinsulinemic hypoglycemia in both subjects was triggered by severe liver injury, at least in part, due to possible limited liver glycogen store. In elderly subjects with low body weight and/or malnutrition, metabolism in the liver is reduced and glycogen accumulation is decreased. Such alteration brings out acute and marked liver injury, which finally leads to the onset of severe hypoglycemia. It is known that not only liver injury but also multiple organ failure could be induced due to extreme emaciation in subjects. It is likely that in elderly subjects with low body weight and/or malnutrition, multiple organ failure including liver failure could be induced due to the similar reason. Therefore, we should be very careful of such subjects in order to avoid the development of multiple organ failure which leads to life-threatening situations. In conclusion, we should keep in mind the possibility of hypoinsulinemic hypoglycemia when we examine severe liver injury, especially in elderly or starving subjects with low body weight and limited liver glycogen stores. LEARNING POINTS: It is important to classify secondary hypoglycemia and hypoinsulinemic hypoglycemia.Liver injury-induced hypoglycemia is one of the causes of hypoinsulinemic hypoglycemia but rarely observed in everyday clinical practice.Herein, we reported similar 2 cases of hypoinsulinemic hypoglycemia without diabetes presumably triggered by severe liver injury.In both cases, hypoglycemia was improved by glucose infusion, although their liver injury was not improved.We should keep in mind the possibility of hypoinsulinemic hypoglycemia when we examine severe liver injury, especially in elderly subjects with low body weight.

Ceftriaxone-associated pancreatitis captured on serial computed tomography scans.

A 74-year-old man was treated with ceftriaxone for 5 days and subsequently experienced epigastric pain. Computed tomography (CT) was performed 7 and 3 days before epigastralgia. Although the first CT image revealed no radiographic signs in his biliary system, the second CT image revealed dense radiopaque material in the gallbladder lumen. The third CT image, taken at symptom onset, showed high density in the common bile duct and enlargement of the pancreatic head. This is a very rare case of pseudolithiasis involving the common bile duct, as captured on a series of CT images.

Correlation between serum cytokeratin-18 and the progression or regression of non-alcoholic fatty liver disease.

BACKGROUND: Diagnosis of non-alcoholic fatty liver disease (NAFLD) is limited by the need for liver biopsies. Serum cytokeratin 18 (CK-18) levels have been investigated as potential biomarkers for the presence of NAFLD and non-alcoholic steatohepatitis (NASH). Herein, we assessed the correlation between CK-18 levels and NAFLD progression. MATERIAL AND METHODS: Serum CK-18 levels were estimated using the M30 antibody enzyme-linked immunosorbent assay in 147 patients diagnosed with NAFLD. In 72 patients, disease progression was evaluated by repeated liver biopsy, which was conducted after 4.3 ± 2.6 years. The relationship between the CK-18 levels and liver histological findings was assessed. RESULTS: The CK-18 levels were useful for identifying NAFLD patients with NAFLD activity scores (NAS) ≥ 5 (NAS ≥ 5 vs. ≤ 4: 675.1 U/L vs. 348.7 U/L; p < 0.0001). A cut-off value of 375 U/L was calculated using the receiver operating characteristic curve approach, with a specificity and sensitivity of 81.5 and 65%, respectively, for the diagnosis of NASH. Among the 72 patients who underwent repeated liver biopsy, 11 patients with a progressed NAS also had significantly increased serum CK-18 levels (p < 0.01); in 30 patients with an improved NAS, there was a significant improvement in the mean CK-18 levels (p < 0.0001). The 31 patients with static NAS had static CK-18 levels. CONCLUSIONS: In conclusion, serum CK-18 levels can predict NAS ≥ 5 in NAFLD patients. In NAFLD patients, serum CK-18 levels reflect NAS values and correlate with histological changes, and they appear to be useful indicators of progression and improvement.
