Details and patient eligibility

About

Infections are proposed risk factors for type 1 diabetes in children. The investigators will examine whether a diagnosis of infectious disease also confers an increased risk of latent autoimmune diabetes in adults.

Full description

The investigators will use data from a population-based Swedish case-control study (ESTRID) with incident cases of LADA (n=597) and matched controls (n=2386). History of infectious disease are ascertained through national and regional patient registers. The investigators will estimate adjusted odds ratios (OR) with 95% CI for ≥1 respiratory (any/upper/lower), gastrointestinal, herpetic, other or any infectious disease episode, or separately, for 1 and ≥2 infectious disease episodes, within 0-1, 1-3, 3-5 and 5-10 years before LADA diagnosis/matching. Stratified analyses will be performed based on HLA risk genotypes and GADA levels.
