    Notes: Abstract Reduced exocrine pancreatic function has been observed in a high percentage of patients with type 1 diabetes in the past. There are only few data for type 2 diabetes available and they are contradictory. In this study we investigated exocrine pancreatic function in 105 controls and 114 with type 1 or type 2 diabetes mellitus by means of an indirect test (faecal elastase-1 concentration). This test has good sensitivity and specificity for moderate and severe pancreatic insufficiency as compared to the gold standard. Reduced faecal elastase-1 concentrations were found in 56.7% of type 1 patients, 35% of type 2 patients and 18.1% of the controls. Elastase-1 concentrations did not correlate with alcohol consumption, diabetes duration or diabetes therapy. The data found for type 1 patients correspond to those reported in earlier studies. The results for type 2 diabetics show that exocrine pancreatic function is also impaired in a high percentage in this group of patients. Pathogenic concepts to explain these findings as consequences of diabetes complications or insulin deficiency are still under debate. Observations from autopsies and the data of the controls in this study suggest that chronic pancreatitis might be a common problem. In consequence, diabetes secondary to exocrine disease could be much more frequent than believed so far.

    Notes: Abstract Post-endoscopic retrogradecholangiopancreatography (ERCP) pancreatitis has beensuggested as a model for acute pancreatitis (AP), whichallows evaluation of early alterations in the timecourse of the disease. The influence of the clinical courseon procalcitonin (PCT), serum amyloid A (SAA), andseveral proinflammatory and inhibitory cytokines wasevaluated in patients with AP following ERCP. Blood samples were prospectively collected frompatients undergoing ERCP. The incidence of ERCP-inducedpancreatic damage, defined as abdominal complaints, athreefold increase of serum lipase, and elevation of CRP from 〈10 to 〉20 mg/liter was 12.8%(12/94). Only mild clinical courses of acutepancreatitis were observed. PCT significantly increasedin subjects with post-ERCP pancreatitis after 24 hr. However, PCT levels did not exceed 0.5 ng/ml inany patient. Interleukin-1 receptor antagonist (IL-1RA)began to differ from baseline 2 hr after ERCP, followedby interleukin-6 (IL-6, 6 hr), solubilized tumor necrosis factor-α receptor II(sTNF-αRII, 24 hr) and SAA (24 hr). Interleukin 10(IL-10) showed marked interindividual variations with noobvious peak. Among all parameters evaluated, only peak values of IL-6 and IL-10 showedsignificant correlations with the reported pain score(r2 = 0.62/0.78), degree of ampullarirritation (r2 = NS/0.87), and the durationof ERCP (r2 = 0.58/0.76). No correlation was found with the volume of theinjected contrast agent. We conclude that IL-10 and IL-6appear to be useful to monitor patients after ERCP. Theabsence of any PCT elevation in the present study is in accordance with the clinical courseof the patients who suffered from mild pancreatic damagewithout systemic or infectious complications.
