“…There is an association between T1D and the development of other autoimmune diseases (AIDs), where coeliac disease (CD), thyroid disease, Addison´s disease and vitiligo are the most known, but there are also descriptions of an increased frequency of multiple sclerosis and juvenile idiopathic arthritis (104)(105)(106)(107)(108)(109)(110)(111). The excess risk of AIDs in T1D can be partly attributable to genetic susceptibility and the expression of certain HLA alleles as well as immunological imbalances such as an imbalance in B and T lymphocytes, an increased tendency to react against certain antigens or a poor ability to develop tolerance to autoantigens (107,112,113).…”
