Systematic Analysis and Network Mapping of Disease Associations in Autoimmune Polyglandular Syndrome

J Clin Endocrinol MetabPublished Retrospective cohort study

Authors' conclusion

APS is more frequent than reported. Classifying APS requires a shift of perspective toward disease associations rather than disorder prevalence.

Study context

Population
Patients whose medical records were analysed; autoimmune origin proved in 3180, of whom 380 had autoimmune polyglandular syndrome (APS)380 with APS
Participants
7,559 patients
Outcome
APS frequency and component disorders
Methodological detailscomputational network analysis of disease associations
  • Computational network analysis of disease associations

Main finding

As reported in the abstract

APS among patients with proved autoimmune origin
380 (12%)
Distinct autoimmune disorders diagnosed
28
Combinations formed
113
Share of cases from the 10 most frequent combinations
51.3%

Observational data: associations, not effects.

Further findings

Age at APS onset by sex

APS started significantly earlier in men than in women

Association patterns

HT and GD were the main cornerstones of APS, sharing several comorbidities
Thyroid autoimmunity frequently linked to gastrointestinal and systemic manifestations; patterns substantially differed from T1D, Addison's disease or coeliac disease as first manifestations
