Official Title: Descriptive and Prognostic Study of Arbovirus Infections in France, Based on a Hospital Cohort of Children and Adults With Suspected Arbovirose.r

Brief Summary:

Arbovirus is term used to refer to a group of viruses that are transmitted by blood-feeding arthropods. The word arbovirus is an acronym (Arthropod-Borne virus). There are hundred which have been shown to cause disease in humans. The incubation period is short usually limited between 1 and 15 days. Among case in which symptoms do appear, the most common clinical features of infection are 4: algo-eruptive (dengue, chikungunya, Zika virus disease...), hemorrhagic fever (dengue, yellow fever, Crimean-Congo hemorrhagic fever), neurological (West Nile virus disease, Zika virus disease, Japanese encephalitis.) or arthritic afflictions, (Chikungunya, O'nyong nyong…).

Dengue is a mosquito-born viral disease caused by four different serotypes of dengue virus (DENV). Dengue fever (DF) is defined by the sudden onset of fever associated with non specific constitutional symptoms, recovery occurring spontaneously after three to seven days.

The infection can sometimes progress to dengue hemorrhagic fever (DHF), a disease characterized by a transient increase in vascular permeability provoking a plasma leakage syndrome. DHF can be complicated by shock and internal hemorrhage. Other rarer but potentially life-threatening complications include encephalitis, hepatitis, rhabdomyolysis, and myocarditis.

There is currently no way of predicting the outcome of DF or DHF, and the World Health Organisation (WHO) classification lacks sufficient sensitivity and specificity to recognize and guide the management of severe forms of dengue. The pathophysiology of these severe forms is also poorly known, but it involves both host characteristics (immunological facilitation in case of new infection by a different serotype, and genetic factors), and viral factors.

Principal objective To identify demographic, clinical, biological, virologic, immunologic and genetic factors associated with or predictive of severe complications of arbovirus infections (shock, internal bleeding, organ failure, death) in a cohort of children and adults with confirmed arbovirus infections, in France.

Secondary objective

To identify demographic, clinical, biological, virologic, immunologic and genetic factors predictive of altered quality of life after confirmed an acute arbovirus infection. Onset of specific complications:

  • Hemorrhagic fever (dengue :WHO criteria..)
  • Neurological disorders (West Nile virus infection, Zika virus infection, Japanese encephalitis…)
  • Chronic chikungunya (persistent musculoskeletal symptoms for more than three months after symptoms onset)

Current Primary Outcome: Occurrence, during follow-up (for 12 weeks following symptom onset), of shock, internal bleeding, failure of one or several organs or systems (brain, heart, lung, liver, kidney, clotting system), or death. [ Time Frame: 12 weeks ]

Original Primary Outcome: Same as current

Current Secondary Outcome: Onset of dengue hemorrhagic fever (WHO criteria). Changes in quality of life, measured with the EuroQol® questionnaire 3 and 12 weeks after the onset of dengue fever symptoms. [ Time Frame: 12 weeks ]

Original Secondary Outcome: Same as current
