It is known that the association with Down syndrome (DS) can affect the phenotypic expression of autoimmune thyroid diseases (AITDs), whilst is unknown whether the clustering of extra-thyroidal autoimmune diseases (ETADs) may also be atypical in DS children. The aim of this study was to investigate the clustering of ETADs in 832 children with AITDs divided in two groups with or without DS (A and B, respectively) and in four subgroups of patients aged either <6 or ≥6 years. The rate of children with ETADs was significantly higher in Group A; in particular, alopecia areata (p=0.00001) and vitiligo (p=0.00001) were found more often in Group A irrespective of age, whilst the distribution of T1 diabetes mellitus was not different in the two groups. Celiac disease prevalence was significantly higher in DS patients only in the older subgroup. The association with DS may be able to modify the clustering of ETADs in the children with AITDs by favoring the aggregation of some specific diseases such as alopecia areata and vitiligo

Abstract
It is known that the association with Down syndrome (DS) can affect the phenotypic expression of autoimmune thyroid diseases (AITDs), whilst is unknown whether the clustering of extra-thyroidal autoimmune diseases (ETADs) may also be atypical in DS children. The aim of this study was to investigate the clustering of ETADs in 832 children with AITDs divided in two groups with or without DS (A and B, respectively) and in four subgroups of patients aged either <6 or ≥6 years. The rate of children with ETADs was significantly higher in Group A; in particular, alopecia areata (p=0.00001) and vitiligo (p=0.00001) were found more often in Group A irrespective of age, whilst the distribution of T1 diabetes mellitus was not different in the two groups. Celiac disease prevalence was significantly higher in DS patients only in the older subgroup. The association with DS may be able to modify the clustering of ETADs in the children with AITDs by favoring the aggregation of some specific diseases such as alopecia areata and vitiligoI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
