title: [Chronic pancreatitis as a possible result of analgesic abuse].
abstract: Abuse of analgesics (AA) is a well known cause of chronic interstitial nephritis. Recently a noxious effect of AA on the pancreas has been suggested based upon case observations, and first evidence for association of AA with chronic pancreatitis was presented. In the present prospective clinical study 95 patients with chronic renal insufficiency, in 53 of them associated with AA, were investigated for evidence of chronic pancreatitis (e.g. history of pancreatitis, pancreatic calcifications, diabetes and exocrine function). The patients were divided into two groups: group A consisted of 53 patients with chronic nephropathy associated with AA, and control group B consisted of 42 patients with chronic nephropathy of other etiology. Pancreatic calcifications were observed in 5 cases of group A (10%), but in none of the patients of group B. Exocrine insufficiency was found in 2 of the 5 cases with pancreatic calcifications. Only one of the 5 patients had a history of pancreatitis in association with exocrine and endocrine insufficiency. Thus pancreatic calcifications, which are virtually pathognomonic for chronic pancreatitis, were found exclusively in the group with chronic nephropathy due to analgesic abuse. Chronic pancreatitis in this group of patients is likely to be overlooked because of the lack of clinical and laboratory evidence. The present data support our previous observations that AA may be an etiological factor in chronic calcifying pancreatitis. This first evidence for a drug-induced form of chronic pancreatitis is presented.
