Soluble forms of ICAM-1 (sICAM-1) and VCAM-1 (sVCAM-1) have been reported from the supernatant of cytokine-activated endothelial cells, cancer cells and from sera of cancer patients. We measured sICAM-1 and sVCAM-1 from the serum of 20 healthy volunteers and 142 gastric cancer patients by ELISA assay. Ninety-five patients were operable and 47 patients were in-operable at the time of this study. Particularly in the 28 operable patients, we sampled both portal and peripheral blood simultaneously and measured the levels of the soluble forms of cell adhesion molecules (sCAMs). The sCAMs level and sero-positivity rate increased with cancer progression in order of the healthy controls, operable patients, and inoperable patients. In in-operable cancer, the sICAM-1 level increased more with liver metastasis. sICAM-1 and sVCAM-1 did not correlate with each other in either portal or peripheral blood. A total of 58.3% of patients with liver metastasis and 22.9% of patients without liver metastasis showed synchronous expression of both sCAMs (p = 0.03). Synchronous sero-positivity of sCAMs and alpha FP was higher with liver metastasis (p = 0.01). The median overall survival duration which co-expressed both sCAMs was 9 months. This showed a significant difference compared with the sICAMs non-expressing group, where the median survival was not reached until 24 months follow-up (p = 0.002). The synchronous expression of sCAMs was an independent risk factor in gastric cancer patients. We raise the possibility that synchronous sICAM-1 and sVCAM-1 elevation may be a useful monitor to determine tumor burden in gastric cancer.

We performed a bentiromide test in 25 patients with chronic pancreatitis and 7 normal controls to evaluate pancreatic exocrine function, and compared the test results of patients with their endoscopic retrograde pancreatography(ERP) findings. The cumulative 6-hour recovery rate of para-aminobenzoic acid(PABA) in the urine was significantly lower in patients with chronic pancreatitis(55.8 +/- 24.2%) than in controls(82.0 +/- 10.0%). Among 25 patients with chronic pancreatitis, however, 7 patients showed normal recovery rates of PABA. Pancreatograms of the patients represented 4 mild changes, 5 moderate changes, and 16 marked changes. The average 6-hour recovery rates of PABA of the groups were 56.9 +/- 21.6%, 78.4 +/- 10.5%, and 47.2 +/- 23.7%, respectively. Urinary PABA recovery rates were found subnormal as follows: 3(75%) in the mild changes group; 1(20%) in the moderate changes group; and 14(87.5%) in the marked changes group. We found hardly any correlation between the degree of functional impairment and the changes noted by ERP. These findings suggest that both the pancreatic function test and morphologic study are required to evaluate the degree of functional impairment in patients with chronic pancreatitis.

To determine the prevalence and clinical relevance of HGV infection in dialysis patients, we performed a cross-sectional study of 61 HD patients and 79 Continuous Ambulatory Peritoneal Dialysis (CAPD) patients. HGV-RNA was identified by reverse-transcription (RT) polymerase chain reaction (PCR) assay with primers from the 5'-untranslated region of the viral genome. The prevalence of HGV infection was similar in HD and CAPD patients (9.8% vs. 12.7%), while that of HCV infection was significantly higher in HD patients compared to CAPD patients (16.4% vs. 1.3%, p < 0.05). The mean age (49.2 +/- 13.4 vs. 46.7 +/- 13.0 years), male to female ratio (2.4:1 vs. 1.3:1), history of transfusion (62.3% vs. 49.4%), history of hepatitis (27.9% vs. 26.6%), mean ALT level during the previous 6 months (22.4 +/- 37.9 vs. 14.0 +/- 7.4 IU/L), and the prevalence of HBsAg (8.2% vs. 6.3%) showed no difference between HD and CAPD patients. In both HD and CAPD patients, the presence of HGV RNA was not related to age, sex, duration of dialysis, history of transfusion, history of hepatitis, or to the presence of HBV or HCV markers. There was no significant difference in the clinical and biochemical data between patients with isolated HGV infection (n = 12) and patients without viremia (n = 106). The clinical feature of patients coinfected with HGV and HBV (n = 2), or HGV and HCV (n = 2) seemed to be similar to those of patients with isolated HBV (n = 8) or HCV (n = 9) infection. In conclusion, the prevalence of HGV infection was not different between HD and CAPD patients, and HGV infections did not seem to be associated with clinically significant hepatitis. The routes of HGV transmission, other than transfusion or contamination during HD procedure, were suspected.

Serum gastrin and pepsinogen concentrations were measured in 51 children infected with Helicobacter pylori, to investigate the clinical significance and influence of CagA and VacA on serum concentrations of these peptides. CagA+ was 44/51 (86%) and VacA+ was 42/51 (82%). Type I (CagA+/VacA+) included 39/51 (76%), type II (CagA-/VacA-) was 4/51 (8%), and intermediate (CagA-/VacA+, CagA+/VacA-) was 8/51 (16%). There was no significant correlation between endoscopic diagnosis and the state of CagA/VacA. Serum gastrin concentrations were not significantly correlated with the state of CagA/VacA. Serum pepsinogen I and II concentrations were significantly higher in CagA+ than in CagA-, but there was no significant difference between VacA+ and VacA-, Serum pepsinogen I/II ratio was not significantly correlated with the state of CagA/VacA. There was no significant difference between serum concentrations of gastrin, pepsinogen I and H. pylori phenotypes. However, pepsinogen II concentration was significantly higher in type I than type II. Pepsinogen I/II ratio was significantly lower in type I and intermediate than in type II. These findings suggest that CagA positively and phenotype of H. pylori could play a role in the development of upper gastrointestinal diseases in children.

Acute gastroparesis in Duchennes muscular dystrophy.

Duchenne's muscular dystrophy (DMD) is an X-linked recessive disease. Clinical descriptions of the disorder focus principally on skeletal muscle degeneration. Another manifestation, which involves the gastrointestinal tract, may be fatal. But its prevalence remains undefined. We report here a case of acute gastroparesis associated with Duchenne's muscular dystrophy. In our case, the patient's symptoms were improved by prokinetic agents and timely decompression in life-threatening acute gastric dilatation.
