Study summary

It is not known whether there is a different clinical profile of dengue in patients with immune system dysfunction. Preliminary data and previous literature suggest that autoimmune diseases, and in particular their treatment, may favour the evolution to severe forms of dengue.

Our research hypothesis is that the clinico-biological presentation of dengue might be different in case of autoimmune disease, either on the side of overactivation (autoimmune and auto inflammatory diseases without treatment) or immunodepression (autoimmune and auto inflammatory diseases under immunosuppressive treatment).

Study population

Patients with systemic autoimmune disease who have contracted a proven episode of dengue in 2020-21. Only patients followed up at the University Hospital of La Reunion or the Centre Hospitalier Ouest Reunion (CHOR), with or without immunosuppressive treatment will be selected.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≥18 years
  • Patient with or autoinflammatory disease
  • Confirmed diagnosis of dengue (in 2020 or 2021): serological test, antigenic test or PCR test to confirm the diagnosis according to current criteria

Exclusion criteria

Exclusion Criteria:

  • minor
  • opposition to the re-use of data
  • patient not followed in Reunion
  • protected adult (guardianship or curatorship) or under legal protection
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
