ABSTRACT

BACKGROUND/AIMS: The purpose of this study was to examine the roles of tumour necrosis factor-alpha (TNF-alpha), interleukin (IL)-6, IL-18, and alpha-fetoprotein (AFP) in patients with liver cirrhosis (LC) and hepatocellular carcinoma (HCC). METHODOLOGY: AFP and cytokine serum concentrations were determined via EIA or ELISA. RESULTS: In total, 81 patients were included, including 9 healthy controls, 36 LC patients, and 36 HCC patients. Significant differences in AFP, TNF-alpha, IL-6, and IL-18 between the three groups were noted (p < 0.001). AFP was lowest in the healthy subjects, intermediate in LC patients and highest in HCC patients (all p < 0.001). 11-6 and 11-18 concentrations were significantly higher in the HCC group than the other two groups. HCC and LC patients with AFP concentration > 7ng/ml had increased IL-18 concentrations compared to both the other groups p < 0.001). In contrast to previously published studies, TNF-alpha was highest in the healthy group, intermediate in the HCC group, and lowest in the LC group (p < 0.001). CONCLUSIONS: IL-18 may be a potential tumour marker in combination with IL-6 and AFP in the diagnosis of HCC, but further research including a larger population of patients is essential. Further research is warranted.

ABSTRACT

OBJECTIVE: To describe a case of fosinopril-induced severe cholestatic jaundice successfully treated with plasma exchange. CASE SUMMARY: A 78-year-old Taiwanese male presented with yellowish skin and generalized itching one month after starting fosinopril 10 mg once a day. Other drugs taken by the patient were excluded as the probable cause of jaundice. Diagnostic modalities, including abdominal ultrasound, computed tomography, and endoscopic retrograde cholangiopancreatography, revealed no evidence of biliary tract obstruction or intraabdominal tumor. According to the Council for International Organizations of Medical Science (CIOMS) scale, fosinopril was a highly probable cause of the patient's jaundice. Liver biopsy showed cholestasis without bile duct damage. Based on results of the CIOMS scale assessment and pathological characteristics of the liver, the diagnosis was highly probable that fosinopril had induced cholestatic jaundice in our patient. During hospitalization, the patient developed severe jaundice and liver failure, despite conservative treatment and withdrawal of fosinopril. He underwent a 5-day course of plasma exchange therapy, and the serum bilirubin level declined rapidly after treatment. His liver function returned to normal 2 months after treatment. DISCUSSION: Angiotensin-converting enzyme (ACE) inhibitor-induced hepatotoxicity is rare and only a few cases, with most involving captopril, have been reported in the English-language literature. Hepatotoxicity caused by fosinopril is extremely rare. Most ACE inhibitor-induced hepatotoxicity is mild and transient, but it can be fatal. Although orthotopic liver transplantation (OLT) is the standard method for treating drug-induced liver failure, plasma exchange therapy is an alternative therapeutic method or a bridge to OLT for treating liver failure. CONCLUSIONS: Plasma exchange therapy may play a valuable role in the treatment of fosinopril-induced cholestatic jaundice and liver failure. This intervention can be considered for temporary liver support until recovery or OLT.

ABSTRACT

Obscure gastrointestinal bleeding is a very rare entity which accounts for less than 5% of all gastrointestinal bleeding cases. Small bowel tumors are rare but a serious source of obscure gastrointestinal bleeding. Lipomas are the second most common benign tumors in the small bowel and can produce many complications, including gastrointestinal bleeding. Herein, we describe a case of obscure gastrointestinal bleeding caused by a small bowel tumor which was detected by capsule endoscopy and double-balloon enteroscopy preoperatively. Finally, the tumor was surgically confirmed to be a lipoma.

ABSTRACT

Mesenteric ischemia is an uncommon etiology of abdominal pain. Celiac axis compression syndrome is an extremely rare cause of mesenteric ischemia. The primary pathological mechanism is the external compression of the celiac trunk by median arcuate ligament. The clinical manifestation of celiac axis compression syndrome includes postprandial pain, diarrhea, and body weight loss. The diagnosis of this disease is usually difficult and depends on the angiography findings. For treatment, only percutaneous transluminal angioplasty and surgical intervention have been suggested in reviews in the literature. We, herein, report an unusual case of celiac axis compression syndrome and also review the literature pertaining to this disease.

ABSTRACT

Primary Klebsiella pneumoniae liver abscess with metastatic complications is a globally emerging infectious disease and is the leading cause of liver abscess in Taiwan. Host immunity and bacterial virulence, especially of the capsular polysaccharide type, are important in determining clinical manifestations. Investigators retrospectively studied the K pneumoniae genotype and capsular serotype from patients with 37 strains of liver abscess; no correlation was noted with genotype, and many genetically different strains caused liver abscess. Although K pneumoniae is prevalent in patients with diabetes, it can attack healthy or alcoholic people as well. Additional studies are needed to explore the mechanisms of bacterial virulence and to optimize treatment strategies. Physicians should be alert to the illness and its complications.

ABSTRACT

Gallstone ileus is a rare disease and accounts for 1%-4% of all cases of mechanical intestinal obstruction. It usually occurs in the elderly with a female predominance and may result in a high mortality rate. Its diagnosis is difficult and early diagnosis could reduce the mortality. Surgery remains the mainstay of treatment. We report two cases of gallstone ileus. The first was a 78-year old woman who had a 2-d history of vomiting and epigastralgia. Plain abdominal film suggested small bowel obstruction clinically attributed to adhesions. Later on, gallstone ileus was diagnosed by abdominal computed tomography (CT) based on the presence of pneumobilia, bowel obstruction, and an ectopic stone within the jejunum. She underwent emergent laparotomy with a one-stage procedure of enterolithotomy, cholecystectomy and fistula repair. The second case was a 76-year old man with a 1-wk history of epigastralgia. Plain abdominal film showed two round calcified stones in the right upper quadrant. Fistulography confirmed the presence of a cholecystoduodenal fistula and gallstone ileus was also diagnosed by abdominal CT. We attempted to remove the stones endoscopically, but failed leading to an emergent laparotomy and the same one-stage procedure as for the first case. The postoperative courses of the two cases were uneventful. Inspired by these 2 cases we reviewed the literature on the cause, diagnosis and treatment of gallstone ileus.

ABSTRACT

AIM: To investigate the long-term role of a 3-d rabeprazole-based triple therapy in patients with Helicobacter pylori(H pylori)-infected active peptic ulcers. METHODS: We prospectively studied 115 consecutive patients with H pylori-infected active peptic ulcers. H pylori infection was confirmed if any two of H pylori DNA, histology, and rapid urease test were positive. Patients were assigned to either an open-labeled 3-d course of oral amoxicillin 1 000 mg b.i.d., clarithromycin 500 mg b.i.d., and rabeprazole 20 mg b.i.d., or 7-d course of oral amoxicillin 1 000 mg b.i.d., clarithromycin 500 mg b.i.d., and rabeprazole 20 mg b.i.d. Subsequently, all patients received oral rabeprazole 20 mg once daily until the 8th wk. Three months after therapy, all patients were followed-up endoscopically for the peptic ulcer, H pylori DNA, histology, and rapid urease test. One year after therapy, H pylori infection was tested using the 13C-urea breath test. RESULTS: The ulcer healing rates 3 mo after therapy were 81.0% vs 75.4% for the 3-d and 7-d groups [intention-to-treat (ITT) analysis, P = 0.47] respectively, and 90.4% vs 89.6% for the 3-d and 7-d groups [per-protocol (PP) analysis, P = 0.89] respectively. The eradication rates 3 mo after therapy were 75.9% vs 73.7% for the 3-d and 7-d groups (ITT, P = 0.79) respectively, and 84.6% vs 87.5% for the 3-d and 7-d groups (PP, P = 0.68) respectively. One year after therapy, seventy-five patients returned to receive the 13C-urea breath test, and the eradication rates were 78.4% vs 81.6% in 3-d and 7-d groups (PP, P = 0.73) respectively. CONCLUSION: Our study showed the eradication rates against H pylori infection 3 and 12 mo after triple therapy were not different between the 3-d and 7-d rabeprazole-based groups. Therefore, the 3-d rabeprazole-based triple therapy may be an alternative treatment for peptic ulcers with H pylori infection.

ABSTRACT

Gastric bleeding due to graft-vs-host-disease (GVHD) is rare after allogeneic hematopoietic stem cell transplantation, and the interrelationship between endoscopic and histologic assessment has not been well studied. Four patients with documented gastric bleeding due to GVHD were evaluated retrospectively. The endoscopic findings varied markedly and included mild mucosal edema with focal erythema, diffuse erythema with mucosal oozing, and diffuse polypoid indurations with multiple bleeding ulcerations. The histologic features of endoscopic biopsy specimens also varied from scattered apoptotic epithelial cells in one end to denudation of the epithelium with crypt necrosis in the other. The endoscopic findings could not accurately predict the histologic grading of GVHD. Nevertheless, gastric bleeding resolved in 3 patients with increasing intensity of immunosuppression. There was significant disparity between the endoscopic and histologic assessment of the severity of GVHD, and careful adjustment of immunosuppressive therapy might be warranted.

ABSTRACT

BACKGROUND/AIMS: Recurrent ulceration of the stomach occurs in some patients after surgery for peptic ulcer disease. The aim of this study is to evaluate the association of Helicobacter pylori infection with ulcer recurrence in patients after partial gastrectomy due to peptic ulcer disease. METHODOLOGY: A total of 186 patients after partial gastrectomy with Billroth I or Billroth II anastomosis presenting with dyspepsia or bleeding were included. An ulcer recurrence was documented by endoscopic examination. Biopsy specimens were taken from the remnant gastric bodies in all patients. H. pylori infection was diagnosed by either a positive biopsy urease test or the presence of the microorganism on histology. RESULTS: Eighty-three (44.6%) patients among the 186 patients had recurrent ulcers. H. pylori infection was found in 29 (36%) patients in the ulcer group and 42 (41%) patients in the non-ulcer group. The incidence of H. pylori infection did not differ significantly between the two groups (P>0.05). CONCLUSIONS: H. pylori infection may not play an important role in the pathogenesis of recurrent ulcer after partial gastrectomy. Other factors should be studied further.

ABSTRACT

BACKGROUND/AIMS: The aim of our study was to evaluate technetium-99m tetrofosmin SPECT (single photon emission computed tomography) of the chest as a potential non-invasive method to evaluate esophagitis among gastroesophageal reflux disease patients. METHODOLOGY: In this study, we used non-invasive radionuclide imaging technetium-99m tetrofosmin chest SPECT to detect and grade esophagitis in 60 patients with gastroesophageal reflux disease. RESULTS: Based on the endoscopic findings according to the Savary-Miller system, the sensitivity, specificity, and accuracy rates of technetium-99m tetrofosmin chest SPECT in detecting esophagitis were 95.2%, 72.2%, and 88.3%, respectively. The agreement between the endoscopic and technetium-99m tetrofosmin chest SPECT findings was evaluated and found to be good (kappa: 0.633, p < 0.001). CONCLUSIONS: Non-invasive technetium-99m tetrofosmin chest SPECT has excellent sensitivity and good accuracy as a screen for esophagitis among gastroesophageal reflux disease patients.

ABSTRACT

Ga-67 citrate scintigraphy has been routinely and extensively used to evaluate non-Hodgkin's lymphoma (NHL) for more than 20 years. Gastric lymphoma of mucosa-associated lymphoid tissue (MALT) is by far the most common extranodal primary NHL. Gastric MALT lymphoma can be classified as low-grade (LG) or high-grade (HG). Low-grade gastric MALT lymphoma can be cured by eradication of Helicobacter pylori; but radiotherapy and/or chemotherapy and/or surgery are the major methods of treatment for the HG gastric MALT lymphoma. However, it is difficult to differentiate these two groups by clinical parameters and endoscopic findings. The purpose of this study was to determine whether Ga-67 citrate scintigraphy can distinguish the LG gastric MALT lymphoma from the HG gastric MALT lymphoma. Twenty-one patients (11 men and 10 women ranging in age from 38 to 83 years) with histologically confirmed gastric MALT lymphoma were enrolled. Twelve patients had LG and nine patients had HG. All 21 patients underwent Ga-67 citrate scintigraphy before treatment. The results of Ga-67 citrate scintigraphy were classified as positive or negative. In the LG group, nine patients had negative results and three patients had positive results. In the HG group of nine patients, all patients had positive results. Among the three patients who had positive results in the LG group, the uptake of gastric MALT lymphoma was lower than that of the liver. The Ga-67 citrate scintigraphy is of good clinical value for the differentiation of the LG gastric MALT lymphoma and the HG gastric MALT lymphoma. We think that the major value of Ga-67 citrate scintigraphy will be in following the patients with HG gastric MALT lymphoma after treatment to assess response of therapy and to detect possible recurrence and perhaps in determining transformation from the LG to HG gastric MALT lymphoma. However, further investigation is needed to understand the relationship between the uptake of Ga-67 citrate in gastric MALT lymphoma and transformation.
