BAE findings showed that FC was more accurate for predicting endoscopic remission in CD than C-reactive protein, albumin, white blood cell count, and platelet count. Even in small-bowel CD, FC may be a more reliable surrogate marker of endoscopic remission than serological biomarkers.
BackgroundThe relationship between fecal calprotectin (FC) and disease extent in ulcerative colitis (UC) has not been fully elucidated. The aim of this study was to clarify the correlation of FC with disease extent and severity in UC patients.MethodsUC patients scheduled to undergo an ileocolonoscopy were enrolled and fecal samples for FC measurement were collected prior to the procedure. A Mayo endoscopic subscore (MES) was determined for each of 5 colonic segments. To evaluate the association of FC with extent of affected mucosa as well as disease severity, we assessed the correlation of FC level with the sum of MES (S-MES) for the 5 colonic segments as compared to the maximum score of MES (M-MES).ResultsFC measurements in conjunction with findings from 136 complete colonoscopies in 102 UC patients were evaluated. FC level showed a stronger correlation with S-MES (correlation coefficient r = 0.86, p < 0.001) as compared to M-MES (r = 0.79, p < 0.001). In patients with an M-MES of 1, 2, and 3, FC level showed a significant correlation with S-MES (r = 0.67, p < 0.001; r = 0.70, p < 0.001; r = 0.47, p = 0.04, respectively). Our findings indicate that FC level is elevated in patients with greater areas of affected mucosa even in those with the same M-MES value.ConclusionsFC level was shown to be correlated with the extent of affected mucosa as well as severity in UC patients, thus it is useful for precise assessment of mucosal inflammation.
A 50-year-old male underwent abdominal computed tomography at a city hospital in Japan, which revealed a tumor 38 mm in diameter in the tail of the pancreas. Based on findings from endoscopic ultrasonography-guided fine needle aspiration using a 22-gauge needle with a side hole, the tumor was diagnosed as an invasive ductal carcinoma. The patient was referred to our hospital and underwent a distal pancreatectomy. Esophagogastroduodenoscopy performed as part of a medical checkup at another hospital 2 years later revealed a 20-mm-sized submucosal tumor in the posterior wall of the upper body of the stomach. Examination of a biopsy specimen obtained from the top of the lesion revealed adenocarcinoma. Partial resection of the stomach was performed and pathological findings showed an adenocarcinoma in all layers of the stomach wall, consistent with recurrence derived from needle tract seeding of the previously excised cancerous tumor from the pancreatic tail. Additional experimentation performed for confirmation with an agar model showed that agar on the deep side leaked to the shallow side following puncture with a needle with a side hole used with a slow-pull technique.
A 69-year old man came to our hospital complaining of abdominal pain. Contrast-enhanced computed tomography (CT) showed a 65-mm ruptured mass in Couinaud segment 5 of the liver. The mass was treated with emergent transcatheter arterial embolization (TAE), followed by partial hepatectomy. Microscopically, the mass was determined to be an angiosarcoma. Six months previously, enhanced CT had shown a 15-mm mass diagnosed as a cavernous hemangioma in the same region of the liver. Even when the enhancement pattern of a small hepatic mass resembles that of hemangioma, the mass should be reassessed within several months to exclude a diagnosis of hepatic angiosarcoma.
Sserotonin reuptake transporter expression is downregulated in healing colonic mucosa of UC patients and that suppression may be dependent on the presence of remaining low-grade colonic inflammation.
MFG-E8 promotes tumor growth regardless of the presence or absence of colonic inflammation, whereas colon tumor development is initiated by MFG-E8 under inflammatory conditions. These MFG-E8 functions may be dependent on integrin-mediated cellular signaling.
Background and study aims Recurrence of common bile duct stones (CBDS) in patients treated with endoscopic sphincterotomy (ES) can lead to deterioration in their quality of life. Although the pathology and related factors are unclear, we speculated that proton pump inhibiter (PPI) administration increases the risk of CBDS recurrence by altering the bacterial mixture in the bile duct.
Patients and methods The primary endpoint of this retrospective study was recurrence-free period. Several independent variables considered to have a relationship with CBDS recurrence including PPI use were analyzed using a COX proportional hazard model, with potential risk factors then evaluated by propensity score matching analysis.
Results A total of 219 patients were analyzed, with CBDS recurrence found in 44. Analysis of variables using a COX proportional hazard model demonstrated that use of PPIs and ursodeoxycholic acid (UDCA), as well as the presence of periampullary diverticula (PD) each had a hazard ratio (HR) value greater than 1 (HR 2.2, P = 0.007; HR 2.0, P = 0.02; HR 1.9, P = 0.07; respectively). Furthermore, propensity score matching analysis revealed that the mean recurrence-free period in the oral PPI cohort was significantly shorter as compared with the non-PPI cohort (1613 vs. 2587 days, P = 0.014). In contrast, neither UDCA administration nor PD presence was found to be a significant factor in that analysis (1557 vs. 1654 days, P = 0.508; 1169 vs. 2011 days, P = 0.121; respectively).
Conclusion Our results showed that oral PPI administration is a risk factor for CBDS recurrence in patients who undergo ES.
