Pain and aetiological risk factors determine quality of life in patients with chronic pancreatitis, but a brick in the puzzle is missing.

BACKGROUND AND OBJECTIVES: Chronic pancreatitis (CP) is a debilitating fibro-inflammatory disease with a profound impact on patients' quality of life (QOL). We investigated determinants of QOL in a large cohort of CP patients. METHODS: This was a multicentre study including 517 patients with CP. All patients fulfilled the EORTC QLQ-C30 questionnaire. Questionnaire responses were compared to results obtained from a general reference population (n = 11,343). Demographic characteristics, risk factors (smoking and alcohol consumption), pain symptoms, disease phenotype (complications) and treatments were recorded. A multivariable regression model was used to identify factors independently associated with QOL scores. RESULTS: Included patients had a mean age of 56.3 ± 12.8 years, 355 (69%) were men and 309 (60%) had alcohol aetiology. Compared to the reference population, patients with CP had lower global health status (50.5 vs. 66.1; p < 0.001) as well as reduced scores for all functional scales (all p < 0.001). Additionally, CP patients reported a higher burden for all symptom items, with pain being the most prominent complaint (all p < 0.001). Constant pain (coefficient -11.3; p = 0.02), opioid based pain treatment (coefficient -19.7; p < 0.001) and alcoholic aetiology (coefficient -5.1; p = 0.03) were independently associated with lowered global health status. The final multivariable model explained 18% of the variance in global health status. CONCLUSIONS: Patients with CP have significantly lower QOL compared to a population-based reference population. Factors independently associated with a lowered QOL are constant pain, opioid based pain treatment and alcohol aetiology. However, these factors only explain a fraction of QOL and additional factors need identification.

Prospective evaluation of pain control and quality of life in patients with chronic pancreatitis following bilateral thoracoscopic splanchnicectomy.

BACKGROUND: Abdominal pain in chronic pancreatitis (CP) is the most common symptom with a highly unfavorable impact on the quality of life. It has been shown that bilateral thoracoscopic splanchnicectomy (BTS) may produce marked pain relief for the majority of patients. The aim of this study was to evaluate the effectiveness of BTS in pain control and quality-of-life improvement in patients with a severe form of CP. METHODS: Between April 2000 and April 2009, a total of 30 patients qualified for BTS due to CP-related pain. Their age ranged from 28 to 60 years. A 12-month follow-up period was planned for all the patients enrolled. To evaluate effectiveness of BTS, an 11-point Numeric Rating Scale (NRS) and the Quality of Life Questionnaire C-30 (QLQ-C30) in its basic form, developed by European Organization for Research and Treatment of Cancer, were used. An NRS value between 0 and 3 was considered a positive postoperative pain control result. RESULTS: The bilateral splanchnicectomy procedure was performed successfully in 27 of 30 qualified patients. A positive effect based on decreased pain (p < 0.05) at 12 months was achieved in 24 patients (80 %). The initial change in quality of life was not significant but it gradually improved with time (preop vs. 12 months QLQ-C30 score, p < 0.001). CONCLUSIONS: This study showed that BTS is safe and efficacious for pain alleviation in patients with severe CP. It may significantly increase the chances of a long-lasting, life-changing improvement in the quality of life.

Sex and age differences in alcoholic pancreatitis in Japan: a multicenter nationwide survey.

OBJECTIVE: The objective of this study was to clarify the alcohol-drinking habits in patients with alcoholic pancreatitis in Japan. METHODS: A questionnaire was made to ask about the alcohol consumption in patients with alcoholic pancreatitis treated between April 1, 2006, and March 31, 2009. The questionnaire was mailed to 1295 hospitals. RESULTS: Detailed information on the alcohol consumption was obtained in 396 patients with alcoholic acute pancreatitis (338 males and 58 females) and 670 patients with alcoholic chronic pancreatitis (609 males and 61 females). Female patients developed acute pancreatitis 6.8 years or were diagnosed as having chronic pancreatitis 9.7 years earlier compared with male patients. Duration of alcohol consumption was shorter, and cumulative amounts of alcohol consumption before the diagnosis of alcoholic pancreatitis were smaller in female patients than those in male patients. Male smokers developed acute or chronic pancreatitis at younger ages than did nonsmokers. Compared with those who achieved complete abstinence, continued drinking as before increased the risk of recurrence within 2.1 years to 7.1-fold. CONCLUSIONS: Female patients develop alcoholic pancreatitis at younger ages, with shorter duration and smaller cumulative amounts of alcohol consumption than compared with male patients. Male smokers developed alcoholic pancreatitis at younger ages than did nonsmokers. Continued alcohol drinking led to the recurrence of pancreatitis.

Alcohol-associated pancreatitis.

Only a small proportion of heavy drinking individuals develop pancreatitis. The environmental and host cofactors shown to have an association with alcoholic pancreatitis are smoking and race. The known genetic variations and polymorphisms do not seem to play an important role in alcoholic pancreatitis. Newer developments in the understanding of complex disorders allow clinicians to understand better the role of cofactors and interactions between known and yet unknown environmental and genetic factors in causing alcoholic pancreatitis.
