RESUMEN

BACKGROUND & AIMS: Idiopathic chronic pancreatitis (ICP) is the second most common subtype of CP. In 1994, researchers reported the bimodal age at onset of ICP symptoms: early onset ICP (EO-ICP; median age, 19.2 y) and late-onset ICP (LO-ICP; median age, 56.2 y). Ages of onset and clinical features of ICP differed from those of alcohol-related CP (ACP). However, variants in PRSS1 had not yet been associated with ICP. We reexamined ages of onset of ICP in a large, North American cohort of patients, and investigated the effects of genetic factors and alcohol use in patients with EO-ICP, LO-ICP, and ACP. METHODS: We performed a cross-sectional analysis of patients with CP of European ancestry enrolled in the North American Pancreatitis Study 2, a prospective study of 1195 patients with CP from 26 centers in the United States from August 2000 through December 2014. We compared age at onset of symptoms for 130 patients with CP who were lifetime abstainers from alcohol (61 patients with early onset and 69 patients with late onset), 308 light to moderate alcohol drinkers with CP, and 225 patients with ACP and heavy to very heavy alcohol use. DNA from available patients was analyzed for variants associated with CP in SPINK1, CFTR, and CTRC. The Kruskal-Wallis test was used to compare continuous variables across groups and based on genetic variants. RESULTS: Median ages at onset of symptoms were 20 years for patients with EO-ICP and no alcohol use, 58 years for patients with LO-ICP and no alcohol use, 47 years for light to moderate alcohol drinkers with CP, and 44 years for patients with ACP. A higher proportion of patients with EO-ICP had constant pain (65%) than patients with LO-ICP (31%) (P = .04). A higher proportion of patients with ACP had pseudocysts (43%) than patients with EO-ICP (11%) (P = .001). A higher proportion of patients with EO-ICP had pathogenic variants in SPINK1, CFTR, or CTRC (49%) than patients with LO-ICP (23%), light to moderate alcohol drinking with CP (26%), or ACP (23%) (P = .001). Among patients with variants in SPINK1, those with EO-ICP had onset of symptoms at a median age of 12 years, and light to moderate alcohol drinkers with CP had an age at onset of 24 years. Among patients with variants in CFTR, light to moderate alcohol drinkers had an age at onset of symptoms of 41 years, but this variant did not affect age at onset of EO-ICP or ACP. CONCLUSIONS: We confirmed previously reported ages at onset of symptoms for EO-ICP and LO-ICP in a North American cohort. We found differences in clinical features among patients with EO-ICP, LO-ICP, and ACP. Almost half of patients with EO-ICP have genetic variants associated with CP, compared with approximately one quarter of patients with LO-CP or ACP. Genetic variants affect ages at onset of symptoms in some groups.

RESUMEN

DESCRIPTION: Pain in patients with chronic pancreatitis (CP) remains the primary clinical complaint and source of poor quality of life. However, clear guidance on evaluation and treatment is lacking. METHODS: Pancreatic Pain working groups reviewed information on pain mechanisms, clinical pain assessment and pain treatment in CP. Levels of evidence were assigned using the Oxford system, and consensus was based on GRADE. A consensus meeting was held during PancreasFest 2012 with substantial post-meeting discussion, debate, and manuscript refinement. RESULTS: Twelve discussion questions and proposed guidance statements were presented. Conference participates concluded: Disease Mechanism: Pain etiology is multifactorial, but data are lacking to effectively link symptoms with pathologic feature and molecular subtypes. Assessment of Pain: Pain should be assessed at each clinical visit, but evidence to support an optimal approach to assessing pain character, frequency and severity is lacking. MANAGEMENT: There was general agreement on the roles for endoscopic and surgical therapies, but less agreement on optimal patient selection for medical, psychological, endoscopic, surgical and other therapies. CONCLUSIONS: Progress is occurring in pain biology and treatment options, but pain in patients with CP remains a major problem that is inadequately understood, measured and managed. The growing body of information needs to be translated into more effective clinical care.

RESUMEN

Bacillus Calmette-Guerin (BCG) vaccine is traditionally used for vaccination against tuberculosis. BCG vaccine contains live attenuated strain of Mycobacterium bovis. Intravesical BCG is also effective in treatment of transitional cell carcinoma of the urinary bladder. Complications after intravesical BCG immunotherapy are extremely rare. We report an iliac muscle abscess due to M bovis that developed 4 years after intravesical BCG therapy for bladder cancer. Infection with M bovis, though rare, should be considered in patients with prior BCG therapy for bladder cancer.

RESUMEN

BACKGROUND: Hepatic venous pressure gradient (HVPG) measurement correlates with staging of liver fibrosis. Patients with nonalcoholic steatohepatitis (NASH) have a different pattern of fibrosis compared with hepatitis C virus (HCV) with possible alterations in pressures. AIM: The aim of this study was to compare portal pressures with the stage of fibrosis in NASH in comparison with other liver diseases. PATIENTS AND METHODS: Records of all patients who had undergone transjugular liver biopsy with pressure measurements between January 2001 and June 2013 were reviewed. Wedge hepatic venous pressure (WHVP) and HVPG were compared with stages of fibrosis in liver diseases of different etiologies. RESULTS: Among 142 patients included in this study, the liver disease etiology was as follows: HCV (26.6%) and NASH (24.6%), with the remaining (38.7%) grouped under other categories. The mean age of the patients was 51.2±11.5 years, with more men with HCV (73.1%) compared with NASH (51.4%) in terms of etiology (P=0.046). There were strong correlations between the stage of fibrosis with both the HVPG (r=0.64; P<0.0001) and the WHVP (r=0.63; P<0.0001) in NASH patients. Compared with HCV patients, NASH patients had a lower HVPG (3.4±2.4 vs. 7.5±11 mmHg/stage; P=0.01) with a coefficient estimate of -0.24 (P=0.017) and WHVP (9.6±5.5 vs. 14.6±15.2 mmHg/stage; P=0.03) for the stage of fibrosis. CONCLUSION: HVPG and WHVP measurements were strongly correlated with stages of fibrosis in NASH. Patients with NASH had lower HVPG and WHVP for each stage of fibrosis compared with HCV patients. This raises the concern of underestimation of pressures by HVPG in NASH etiology for the stage of disease or increased fibrosis despite lower pressures in them.

RESUMEN

OBJECTIVE: Historically, chronic pancreatitis (CP) was considered a disease of alcoholic males, but recent data suggest its etiology to be complex. To better understand CP in women, we compared data on women and men with CP in a large, prospectively ascertained multicenter US cohort. METHODS: Patients with CP enrolled in the NAPS2 Continuation and Validation study were studied. Information on demographics, etiology, risk factors, phenotype, and treatment(s) used was obtained from detailed questionnaires completed by the patients and physicians. RESULTS: Of 521 cases, 45% were women. Women were significantly (P < 0.05) less likely to have alcohol etiology (30% vs 58.5%) and more likely to have nonalcoholic etiologies (idiopathic, 32% vs 18%; obstructive, 12% vs 2.4%; genetic, 12.8% vs 7.3%). Demographics, pain experience, morphologic findings, exocrine and endocrine insufficiency, CP-related disability, and use of medical therapies were mostly similar in both sexes. Sphincterotomy (biliary, 33% vs 24%; pancreatic, 38% vs 28%; P < 0.05) was performed more frequently in women, whereas cyst/pseudocyst operations were more common in men (6.6 vs 2.6%, P = 0.02). CONCLUSIONS: Most CP cases in women are from nonalcoholic etiologies. In contrast to many other chronic diseases, clinical phenotype of CP is determined by the disease and is independent of sex.

RESUMEN

CONTEXT: Chylous ascites is the accumulation of milky chyle in the peritoneal cavity. Chylous ascites has been reported after surgeries like abdominal aortic aneurysm repair, radical gastrectomy, duodenectomy, nephrectomy and Wilm's tumor resection. Our literature search did not reveal any reports of chylous ascites after a gastric ulcer resection. We report about an elderly woman with a rare complication of chylous ascites after an emergent surgery for a perforated gastric ulcer. CASE REPORT: A 70-year-old woman developed sudden respiratory distress on 5(th) post-operative day after an elective C3-C7 cervical discectomy and fusion. Her past medical history was significant for cervical spondylosis. The Computed Tomography (CT) scan of the chest revealed air under the diaphragm suspicious for hollow viscus perforation. She underwent an emergent surgery for drainage of hematoma in the neck along with an emergent laparotomy to repair a large perforated gastric ulcer distal to the gastro-esophageal junction. The patient had worsening of abdominal distention on 4(th) post-operative day. The CT scan of abdomen showed fluid collection in the abdomen. The abdominal drain revealed large amount of serous milky fluid at the rate of 1500 ml per day. The fluid analysis showed that the triglyceride level was 170 mg/dl and cholesterol level was 15 mg/dl. The fluid cultures did not grow any organism. She responded to treatment with octreotide and a diet of medium chain triglyceride oil. CONCLUSION: Any obstruction or damage to the lymphatic channels results in chylous ascites. Lymphomas, metastatic malignancies, and abdominal surgeries commonly cause chylous ascites. Ascitic fluid triglyceride level greater than 110 mg/dl is diagnostic of chylous ascites. Chylous ascites is a rare complication of a peptic ulcer resection which can be managed effectively with octreotide.
