Background/objectives: Exocrine pancreatic insufficiency (EPI) is an important complication of chronic pancreatitis (CP). Guidelines recommend to rule out EPI in CP, to detect those patients who would benefit from pancreatic enzyme replacement therapy. The aim of this study was to evaluate the prevalence of EPI in patients with CP without follow-up in the last 2 years and to describe their nutritional status and quality of life (QoL)., Methods: This was a cross-sectional, multicenter Spanish study. CP patients without follow-up by a gastroenterologist or surgeon in at least 2 years were included. EPI was defined as fecal elastase test <200mcg/g. For nutritional assessment, laboratory and anthropometric data were obtained. QoL was investigated using the EORTC QLQ-C30 questionnaire., Results: 64 patients (mean age 58.8±10.3 years, 85.9% men) from 10 centers were included. Median time since diagnosis of CP was 58.7 months [37.7-95.4]. Forty-one patients (64.1%) had EPI. Regarding nutritional status, the following differences were observed (EPI vs. Non-EPI): BMI (23.9±3.5kg/m 2 vs. 25.7±2.5, p=0.03); glucose (121 [96-189] mg/dL vs. 98 [90-116], p=0.006); HbA1c 6.6% [6.0-8.4] vs. 5.5 [5.3-6.0], p=0.0005); Vitamin A (0.44mg/L [0.35-0.57] vs. 0.53 [0.47-0.63], p=0.048) and Vitamin E (11.2±5.0μg/ml vs. 14.4±4.3, p=0.03). EPI group showed a worse EORTC QLQ-C30 score on physical (93.3 [66.7-100] vs. 100 [93.3-100], p=0.048) and cognitive function (100 [83.3-100] vs. 100 [100-100], p=0.04)., Conclusions: Prevalence of EPI is high in patients with CP without follow-up. EPI group had higher levels of glucose, lower levels of vitamins A and E and worse QoL., (Copyright © 2017 Elsevier España, S.L.U. All rights reserved.)

This article summarizes some of the recent and clinically relevant advances in chronic pancreatitis. These advances mainly concern the early diagnosis of the disease, the treatment of symptoms and complications, mainly pain and pancreatic exocrine insufficiency, and the diagnosis and therapy of autoimmune pancreatitis. The multimodal dynamic endoscopic ultrasound-guided secretin-stimulated evaluation of the pancreas provides relevant morphological and functional information for the diagnosis of chronic pancreatitis at early stages. Extracorporeal shock wave lithotripsy in patients with calcifying pancreatitis and endoscopic pancreatic stent placement are effective alternatives for pain therapy in patients with chronic pancreatitis. Presence of pancreatic exocrine insufficiency in patients with chronic pancreatitis is associated with a significantly increase of mortality rate. Despite that, pancreatic enzyme replacement therapy is not prescribed in the majority of patients with pancreatic exocrine insufficiency, or it is prescribed at a low dose. The newly developed and commercialized needles for endoscopic ultrasound-guided pancreatic biopsy are effective in retrieving appropriate tissue samples for the histological diagnosis of autoimmune pancreatitis. Maintenance therapy with azathioprine is effective and safe to prevent relapses in patients with autoimmune pancreatitis., (Copyright © 2015 Elsevier España, S.L.U. All rights reserved.)

The incidence of acute pancreatitis (AP) is increasing. AP is one of the gastrointestinal diseases that most frequently requires hospital admission in affected individuals. In the last few years, considerable scientific evidence has led to substantial changes in the medical and surgical treatment of this disease. New knowledge of the physiopathology of AP indicates that its severity is influenced by its systemic effects (organ failure), especially if the disease is persistent, and also by local complications (fluid collections or necrosis), especially if these become infected. Treatment should be personalized and depends on the patient's clinical status, the location of the necrosis, and disease stage., (Copyright © 2014 Elsevier España, S.L.U. and AEEH y AEG.

The most important advances in chronic pancreatitis concern its etiopathogenesis, nutritional aspects, and improvements in diagnostic techniques and some treatment options. In the etiopathogenesis of this disease, the importance of smoking and its association with alcohol have been confirmed. Exocrine pancreatic insufficiency (EPI) secondary to chronic pancreatitis is associated with bone metabolism alterations (osteopenia and osteoporosis), a reduction in liposoluble vitamins and alterations in essential amino acid levels. Endoscopic ultrasound has been confirmed as the most highly developed technique for the diagnosis of chronic pancreatitis, especially due to new image optimization technologies. Breath tests for the diagnosis of EPI continue to be developed (optimization of the C-13 mixed triglyceride test and the development of a new test based on C-13-labelled bicarbonate determination). Modest results in pain treatment have been achieved with the use of antioxidants, pancreatic enzymes and/or intravenous secretin. The association of chronic pancreatitis with pancreatic cancer requires strict follow-up, especially in patients with inflammatory masses in the context of chronic pancreatitis., (Copyright © 2012 Elsevier España, S.L.

A case of malabsorption of pancreatic etiology secondary to primary hyperparathyroidism (HPT) is reported. Normalization of calcemia was achieved with parathyroidectomy and oral administration of pancreatic enzymes was initiated. HPT is an infrequent cause of pancreatic inflammatory disease. Although its association is controversial, its inclusion among the causes of exocrine pancreatic failure allows correct diagnosis and therapeutic management with a favorable prognosis.
