Hereditary chronic pancreatitis in a patient with type 1 diabetes mellitus
Abstract
In this case report, we present a young patient with type 1 diabetes who had hereditary chronic pancreatitis. We evaluated him for the cause of pancreatitis, but it was inconclusive and finally the genetic testing was done for him, which revealed heterozygous missense mutation in exon 3 of the PRSS1 gene (protease serine 1 gene) on chromosome 7. Hence, we were able to make the diagnosis of hereditary chronic pancreatitis. Chronic pancreatitis secondary to any cause can lead to permanent diabetes, which is typically difficult to control. However, in this case, the episodes of recurrent pancreatitis were present after the onset of type 1 diabetes as compared to the usual presentation of diabetes after the advancement of chronic pancreatitis.
