title: Prevalence and clinical features of diabetes mellitus secondary to chronic pancreatitis in Japan; a study by questionnaire.
abstract: The prevalence and clinical features of diagnosed mellitus secondary to chronic pancreatitis (CP) were assessed from northern (Hokkaido) to southern (Okinawa) Japan by means of a questionnaire to elucidate whether WHO-classified malnutrition-related diabetes mellitus (MRDM) exists in Japan. Of a total 17,500 diabetic patients, only two (0.011%)-one fibrocalculous pancreatic diabetes (FCPD) and one protein-deficient pancreatic diabetes (PDPD) - exhibited MRDM characteristics. A total of 649 CP were collected and classified into 268 cases with chronic alcoholic pancreatitis (CAP), 150 cases with chronic calcified pancreatitis (CCP) and 231 cases with other CP. The prevalence of diabetes mellitus was found to be 50.7% in CAP, 72.7% in CCP and 22.8% in other CP. Among all diabetics, 56.6% was noninsulin-dependent (NIDDM) and 26.4% insulin-dependent (IDDM). IDDM was most frequent in CP. Satisfactory and less than satisfactory glycemic control was obtained in approximately three quarters of all subjects. Only one quarter showed poor glycemic control. Insulin treatment was frequent in CAP (52.2%) and CCP (61.7%), but less in other CP (27.5%). The prevalence of diabetic retinopathy was observed in 33.1% of all subjects, nephropathy 21.0% and neuropathy 36.3%, respectively. The prevalence of complications, including macroangiopathy tended to be higher in CAP and CCP (40.3 and 56.9%) than in other CP (31.4%).
