RESUMO
GOALS: To report the clinical profile and natural course in a large series of patients with hypertriglyceridemia (HTG) and acute pancreatitis (AP). BACKGROUND: The natural history of HTG-related pancreatitis is poorly defined. STUDY: Medical records of 121 patients with serum triglycerides (TG) levels of ≥500 mg/dL suffering 225 attacks of AP between January 2001 to August 2013 treated at the University of Pittsburgh Medical Center were retrospectively studied. Structured data were collected on initial presentation and long-term outcomes (mean follow-up 64.7±42.8 mo). AP severity was classified using Revised Atlanta Classification. RESULTS: Most patients were young-middle aged (mean 44±12.7 y), male (70%), white (78%), and had sentinel AP (63%). Peak serum TG recorded was ≥1000 mg/dL in 48%. At least 1 secondary risk factor (diabetes, high-risk drinking, obesity, offending medications) was present in the majority (78%). Sentinel AP attack varied in severity between mild (41%), moderate (26%), and severe (33%). Recurrent AP attacks occurred in 32%, often in patients with poorly controlled diabetes, alcoholism, and TG levels. A cumulative increase in prevalence of pancreatic and/or peripancreatic necrosis was observed, with 45% patients having it at some time during observation. Local complications were higher in patients with serum TG ≥1000 mg/dL. Chronic pancreatitis was noted in 16.5% patients (new-onset in 9%). CONCLUSIONS: Patients with HTG-related pancreatitis have a high prevalence of secondary risk factors. Frequent recurrences in them are usually due to poor control of secondary factors or TG. Serum TG ≥1000 mg/dL increases the risk of local complications. A subset can have or develop chronic pancreatitis.

GOALS: To explore the diagnostic challenges, management, and clinical outcomes of patients with isolated peripancreatic necrosis (PPN), with emphasis on the extent of involvement, and compare them to pancreatic necrosis (PN). BACKGROUND: PPN, a relatively new term, has been included as a separate entity in the Revised Atlanta Classification. STUDY: Clinical data of recruited acute pancreatitis patients were recorded prospectively. Contrast-enhanced computed tomographic scans were reviewed by expert radiologists blinded to clinical outcomes. RESULTS: In total, 271 of the 400 acute pancreatitis patients underwent contrast-enhanced computed tomography, of which 29 (11%) had PPN (14: limited; 15: extensive) and 124 (46%) PN (40: <30%, 16: 30% to 50%, 68: >50% of parenchyma). Patients with PPN were similar to PN in age (56 y), gender (55% male), and body mass index (29 kg/m(2)). Nutritional support was provided in 18 (62%) patients with PPN and 97 (78%) with PN (P=0.12). Drainage/debridement was required in 2 patients (7%) with PPN and 64 (53%) with parenchymal necrosis (P<0.001). Persistent organ failure rates did not differ significantly (34% vs. 51%, P=0.17), but hospital stay was shorter in patients with PPN (15 vs. 20 d, P=0.05). Limited PPN required no intervention and had similar persistent organ failure rates and hospitalization length with interstitial pancreatitis (both P≥0.12). Extensive PPN mainly developed in patients with persistent organ failure (60%) and rarely required drainage (2/15). CONCLUSIONS: PPN prevalence was lower than PN with a ratio of 1:4. PPN rarely required intervention. Utilizing the extent of involvement has the potential to classify PPN and PN with escalating clinical significance and guide management.

BACKGROUND: Anemia is a common manifestation of inflammatory bowel disease (IBD), but its prevalence in the United States is not well defined. Aim of this study was to determine the prevalence and characteristics of anemia in IBD patients who were followed in a US referral center. MATERIALS AND METHODS: Demographic, clinical, laboratory, and treatment data from a prospective, consented longitudinal IBD registry between the years 2009 and 2013 were analyzed. Disease activity was evaluated using Harvey-Bradshaw index in Crohn's disease (CD) and ulcerative colitis (UC) activity index in UC as well as C-reactive protein and erythrocyte sedimentation rate. Anemia was defined based on the World Health Organization criteria. RESULTS: A total of 1821 IBD patients (1077 with CD, 744 with UC, median age 43.8 y, 51.9% female) were included. The 5-year period prevalence of anemia in IBD patients was 50.1%, (CD: 53.3% vs. UC: 44.7%, P=0.001). In multivariate logistic regression analysis, anemia was associated with surgery for IBD [odds ratio (OR)=2.77; 95% confidence interval (CI), 2.21-3.48; P<0.0001], female gender (OR=1.29; 95% CI, 1.04-1.61; P=0.02), C-reactive protein (OR=1.26; 95% CI, 1.16-1.37; P<0.0001), erythrocyte sedimentation rate (OR=1.02; 95% CI, 1.01-1.03; P=0.0002), and use of biologics (OR=2.00; 95% CI, 1.58-2.52; P=0.0001) or immunomodulators (OR=1.51; 95% CI, 1.21-1.87; P=0.0003). Iron replacement therapy was administered to 46.8% of the anemic patients. CONCLUSION: Anemia has a high period prevalence in IBD patients followed at a tertiary center. Anemia is more common in CD than in UC, is associated with disease activity, and in current practice is undertreated.
