Quality of life in patients with chronic pancreatitis.

INTRODUCTION: Health-related quality of life is becoming a major issue in the evaluation of any therapeutic intervention in patients with chronic or hard to cure diseases. AIMS: To assess the quality of life in patients with chronic pancreatitis, the majority of whom have had the disease for a long time, and to evaluate which factors linked to the disease are able to influence the quality of life. SUBJECTS AND METHODS: A total of 190 consecutive patients (157 males, 33 females; mean age 58.6+/-12.7 years, range 18-92 years) with proven chronic pancreatitis were enrolled. The SF-36 questionnaire was used for assessing the health-related quality of life. RESULTS: The z-scores of the eight domains of the patients with chronic pancreatitis were significantly negative indicating an overall impairment of the quality of life when compared to the Italian normative sample. Pancreatic pain was the unique clinical variable able to significantly impair all eight domains of the SF-36, while Wirsung dilation and diabetes were negatively related to some physical and mental domains. The body mass index was the unique variable positively related with some SF-36 domains. CONCLUSIONS: Pain may be considered the most important factor affecting the quality of life of chronic pancreatitis patients; moreover, alimentary and metabolic factors deserve more attention in improving the quality of life of these subjects.

Serum trypsinogen activation peptide in the assessment of the diagnosis and severity of acute pancreatic damage: a pilot study using a new determination technique.

OBJECTIVES: To evaluate the clinical value of a new direct and competitive immunoassay for trypsinogen activation peptide (TAP) determination in acute pancreatitis (AP). METHODS: The subjects were 34 patients with AP (22 mild, 12 severe), 12 patients with nonpancreatic acute abdominal pain (AA), 11 healthy subjects (HS), and 16 consecutive patients who underwent therapeutic ERCP (ERCP). Serum TAP, amylase, and lipase levels were determined in AP, AA, and HS at their initial observation; the AP patients were also studied for 6 consecutive days after admission. In the ERCP patients, serum TAP, amylase, and lipase levels, as well as urine TAP and amylase levels, were determined before and 6 hours after endoscopy. RESULTS: Serum TAP levels on admission were 0.35 +/- 1.60 OD (mean +/- SD) in AP patients and 0.005 +/- 0.001 OD in AA patients, while HS patients had no detectable serum TAP levels. ERCP patients had no detectable serum TAP levels before and 6 hours after the ERCP, whereas urine TAP concentrations were 1.72 +/- 3.43 OD and 0.75 +/- 1.49 OD before and 6 hours after the execution of the endoscopy, respectively (P = 0.249). The sensitivities and specificities of serum TAP, amylase, and lipase levels in discriminating between AP and AA were 23.5% and 91.7%, 94.1% and 100%, and 97.1% and 100%, respectively, while those used in the assessment of the severity of AP were 29.9% and 73.5%, 38.8% and 81.2%, and 28.4% and 83.6%, respectively. CONCLUSION: TAP is of limited value in assessing the diagnosis and the severity of acute pancreatic damage.
