In two previous editorials, I’ve explored some evidence linking type 2 diabetes mellitus (T2DM) to the cytotoxicity of islet amyloid polypeptide aggregates deposited in pancreas and I’ve expressed a strong wish and call to focus on the full of potentials amyloid research as well as on drug development of amyloid antagonists. In this short commentary, I’m trying to search deeper on the relationship between both diseases and whether T2DM can be a consequence of pancreatic amyloidosis [1,2].

Primary amyloidosis was shown to be particularly difficult to diagnose because its signs and symptoms are subtle and because of the absence of specific imaging or laboratory tests, except histopathology [3]. Meanwhile, secondary amyloidosis has been shown to complicate chronic inflammatory autoimmune diseases [4] and chronic diseases such as autoimmune disease and T2DM have also been suggested to be potential factors for AA amyloidosis [5]. Thus, a reciprocal interaction may be also involved; several cases of insulin-derived localized amyloidosis have been reported like those mentioned in [6,7] and a case of primary systemic amyloidosis with the history of T2DM for nine years has also been recently described [8]. Further, Inflammation is known to be closely involved in the pathogenesis of T2DM, and reactive amyloidosis occurs in the presence of chronic inflammation and renal AA amyloidosis was shown to be prevalent in T2DM [9].

I finish this short commentary by referring to one of the first articles published seven years ago and pointed to this important debate; I’ll repeat the authors call for a substantial more work to elucidate the association and/or causation between both diseases; I totally agree with what they’ve written: “keeping an open mind on the nature of the cytotoxic insult has implications for therapeutic developments and clinical care in type 2 diabetes” [10].
